本發明係關於一種利用自然界所產生之風、海水之漲落、波浪、河流之流動等流體之流動或其他再生能源來發電的發電系統，尤佳適合於一種利用平均性低之再生能源、且利用在能源之持續性有其難處之環境下之再生能源的發電系統，及將該等之再生能源暫儲存為位能或彈性能、而將該等之能源作為適宜於發電之能源饋送至發電機之發電系統用位能儲存裝置以及發電系統用彈性能儲存裝置。The present invention relates to a power generation system for generating electricity by using the flow of fluids such as wind, seawater fluctuations, waves, river flows, and other renewable energy generated in nature, and is particularly suitable for a renewable energy source with low averageness, and Power generation system using renewable energy in an environment where energy continuity has its difficulties, and temporarily storing the renewable energy as potential energy or elastic energy, and feeding the energy to the power generation as an energy suitable for power generation Potential energy storage device for electric motor power generation system and elastic energy storage device for power generation system.

一般而言利用再生能源之發電系統係在儘可能持續性獲得高的能源之環境中使用。例如，在風力發電中，朝可期待有強風之海岸或海上、或者山頂、山腰等之設置係主流。再者，其能源接納機構(葉片)配置於數十米之高處。又，在波力發電中，雖實用例甚少，但是若觀察迄今為止已嘗試開發之例，則可知在波浪高為高之海面之設置成為主流。而且，該等幾乎皆為大型設備。 言及再生能源之地域生產、地域消費可謂源遠流長。因此，作為民生品之實用性之中型、小型之設備，且在一般環境之市區之風力發電或在海灣之波力發電等之實現備受期待。然而，現狀係限於極其輔助性之設備，而尚未實現具有作為替代之電力產生機器之能力的設備。其最大之理由係緣於所設置之環境。 若以風力發電為例，則可知東京都內之高樓之屋頂的年間平均風速為3 m左右。無風之日多，能源之持續性亦差。在販賣的民生用之風力發電機之中，有號稱具有2000 kWh之發電能力的產品，此係以風速15 m之強風時為前提之能力，在都市中一年亦無幾次強風。若實際上在如東京都內之年間平均風速3 m(前述風速之5分之1)之環境下使用如此之產品，則會產生如下之各種問題，而發電力降低至前述風速之20分之1的100 kWh左右。 1. 在微風時，會產生因系統之機械性負載，例如葉片(翅片)等之重量、馬達軸之轉矩等而導致葉片不旋轉此般能源接納部之閾值之問題。 2. 即便達到葉片(翅片)轉動之風速，但會產生若發電機之馬達達不到直至發電為止的旋轉速度則不能形成可利用之電力此般發電系統之閾值之問題。 3. 即便達到可發電之旋轉速度，但會產生因系統內之負載導致之電力損耗而造成接納能源被消費此般發電效率之問題。 4. 即便風力使葉片旋轉而產生充分之電力並儲存於電池等之蓄電裝置，但會產生若無風而不發電之時間長期持續則在電池內會自然放電此般因發電之非持續性導致之電池等蓄電裝置之蓄電性能之問題。 另一方面，在以波浪之上下運動(波浪高)為能源之波力發電中，相對於海上之年平均數米之波浪高，作為民生用的實用設置環境之海之海灣等係年平均為數10釐米之波浪高，若將波浪高改換為風速則毫無疑問會產生與風力發電完全相同之問題。 為了解決如此之問題，提議有利用可以低速發電之多極發電馬達或電力之電腦控制而進行之電池充電器等，但現狀係均收效甚微卻價格高昂，在相對費用效果之點上不被採用。自如此之情形而言，業界追求一種可供民生用之小型、中型之即便在再生能源環境差之民生環境中亦可實用之發電系統。 在日本特開2008-75640號公報中，揭示有意欲利用將本質性能源作為周圍環境之熱之藉由熱力學循環之重複而動作的所謂「飲水鳥」之原理的動力產生裝置，但其係利用溫度差者，若在再生能源環境差之民生環境中使用則不能謂之為有效之裝置。 在日本特開2014-101879號公報中，揭示有改良上掛式水車的利用水等之荷重物之位能之荷重利用裝置，但其係利用水流之高低差者，若在再生能源環境差之民生環境中使用則不能謂之為有效之裝置。 在日本專利5524409號公報中，揭示有利用風、潮流、海流、河流等之可再生能源，經由傳動裝置，將旋轉軸之旋轉傳遞至發電機而生成電力，並將該電力供給電力系統之再生能源型發電裝置。然而，該裝置若在再生能源環境差之民生環境中使用亦不能謂之為有效之裝置。 在日本特開平10-131841號公報中，揭示有一種力學能源儲存式發電裝置，其具備：力學能源儲存機構，其藉由利用外力使彈性體變形而儲存外部能源且將所儲存之外部能源以大致一定之功率輸出；發電機構，其將利用前述力學能源儲存機構輸出之外部能源轉換為電力；及整流機構，其將利用前述發電機構轉換之電力予以整流；作為彈性體係例示有盤簧、螺簧、板簧、橡膠、形狀記憶合金等。 在該發明中，使力學能源儲存至儲存機構之外力係人力，例如，記載有藉由利用手指捏住轉動旋鈕使其轉動，藉而盤簧被捲入動力輸入軸，而外部能源被儲存至盤簧。 在日本特開2002-84726號公報中，揭示有一種卡片型發電機，其特徵在於係將利用其本身被移動而產生之動能轉換為電能者，並將發電機構內置於形成為卡片型之殼體，且該發電機構具備：機械能轉換機構，其接受前述動能而轉換為機械性之能源；機械能儲存機構，其儲存該機械能轉換機構所轉換之機械能；及發電機構，其被自該機械能儲存機構輸出之機械能驅動而產生電力。而且，作為機械能儲存機構，例示有藉由旋轉錘之旋轉而變形，利用該變形來儲存前述機械能之彈性體(例如盤簧)。並且，所利用之動能係藉由攜帶者之步行等而產生之動能，雖係間接性但為人力。 在日本特開2003-278216號公報中，揭示有用於朝自動噴水裝置供給電能之電源裝置，其構成為具備：力學能源儲存機構，其將水之動能(流經通水路中之水之動能)暫時地作為力學能源而儲存；發電機構，其將前述力學能源朝電能轉換；及蓄電機構，其儲存利用前述發電機構獲得之電能；且作為力學能源儲存機構例示有儲存力學能源的盤簧或橡膠、彈簧等之彈性體。而且，所使用之動能係流經通水路中之水之動能。 在日本特開2004-260896公報中，揭示有利用小齒輪之旋轉使發電機構來發電之發電機，其具備：齒條，其在一方向上具有長邊方向；小齒輪，其藉由相對於齒條之相對移動而轉動；及發電機構，其利用小齒輪之旋轉力而發電；且若被賦予具有一方向之成分之運動力，則齒條與小齒輪沿一方向進行相對移動，利用該相對移動而小齒輪旋轉。而且，於齒條及小齒輪之至少任一者上，設置有反力賦予機構(彈性體)，其對該任一者之相對移動方向賦予相反方向之反力，作為彈性體例示有螺簧、板簧、橡膠等。Generally speaking, a power generation system using renewable energy is used in an environment where the highest energy source is obtained as continuously as possible. For example, in wind power generation, installation on the coast or sea where a strong wind can be expected, or on the top of a mountain or a mountainside is the mainstream. Furthermore, its energy receiving mechanism (blade) is arranged at a height of tens of meters. In wave power generation, although there are few practical examples, if you look at the examples that have been tried so far, it can be seen that the installation on the sea surface where the wave height is high has become the mainstream. Moreover, these are almost all large-scale equipment. Speaking of regional production and regional consumption of renewable energy, it can be said to have a long history. Therefore, as a practical medium-sized and small-scale device for people's livelihood, the realization of wind power generation in the urban area of the general environment or wave power generation in the bay is expected. However, the status quo is limited to extremely auxiliary equipment, and equipment having the ability to substitute electric power generating machines has not yet been realized. The biggest reason is the environment. If wind power is taken as an example, it can be seen that the annual average wind speed of the roofs of tall buildings in Tokyo is about 3 m. There are many days without wind, and the sustainability of energy is also poor. Among the wind power generators sold for people's livelihood, there are products with a claimed power generation capacity of 2000 kWh. This is based on the premise of strong wind speeds of 15 m, and there are no strong winds in the city several times a year. If such a product is actually used in an environment with an average annual wind speed of 3 m (1/5 of the aforementioned wind speed) in Tokyo, the following problems will occur, and the power generation will be reduced to 20 times of the aforementioned wind speed. About 100 kWh. 1. In the breeze, the threshold of the energy receiving part such as the blade does not rotate due to the mechanical load of the system, such as the weight of the blade (fin) and the torque of the motor shaft, will occur. 2. Even if the wind speed at which the blades (fins) rotate is reached, there will be a problem that if the generator's motor cannot reach the rotation speed until power generation, the threshold of a power generation system such as available power cannot be formed. 3. Even if the rotating speed capable of generating electricity is reached, the problem of generation efficiency such as receiving energy is consumed due to the power loss caused by the load in the system. 4. Even if the wind rotates the blades to generate sufficient power and store it in a power storage device such as a battery, it will naturally discharge in the battery if the power generation time without wind continues for a long period of time. This is caused by the non-continuity of power generation. Problems with the power storage performance of power storage devices such as batteries. On the other hand, in wave power generation that uses waves moving up and down (wave height) as the energy source, the average annual number of waves, such as the sea height of the sea, which is a practical setting environment for the people's livelihood, is equal to the annual average number of meters. A wave height of 10 centimeters. If the wave height is changed to wind speed, it will undoubtedly cause exactly the same problem as wind power generation. In order to solve such a problem, it is proposed to use a multi-pole generator motor capable of low-speed power generation or a battery charger for computer control of electric power. However, the current situation is that the results are very small but the price is high, which is not affected by the relative cost effect. use. From this point of view, the industry is pursuing a small, medium-sized power generation system that can be used for people's livelihood, even in a livelihood environment where the renewable energy environment is poor. Japanese Patent Application Laid-Open No. 2008-75640 discloses a power generating device that uses the principle of a "drinking bird" that intends to use the essential energy as the heat of the surrounding environment to operate by repetition of thermodynamic cycles. If the temperature is poor, it cannot be regarded as an effective device if it is used in a livelihood environment where the renewable energy environment is poor. Japanese Patent Application Laid-Open No. 2014-101879 discloses a load utilization device that improves the potential energy of a load such as a water tank using a load, but it is a person who uses the difference in the level of water flow. It cannot be regarded as an effective device when used in the people's livelihood environment. Japanese Patent No. 5524409 discloses the use of renewable energy sources such as wind, currents, currents, rivers, etc., to transmit the rotation of a rotating shaft to a generator via a transmission device to generate electricity, and to supply the electricity to the regeneration of the power system. Energy-based power plant. However, the device cannot be regarded as an effective device if it is used in a livelihood environment where the environment of renewable energy is poor. Japanese Patent Application Laid-Open No. 10-131841 discloses a mechanical energy storage type power generation device including a mechanical energy storage mechanism that stores external energy by deforming an elastic body using an external force and uses the stored external energy to Approximately a certain power output; a power generation mechanism that converts external energy output from the aforementioned mechanical energy storage mechanism into electricity; and a rectification mechanism that rectifies the power converted by the aforementioned power generation mechanism; as an elastic system, coil springs, spiral screws, etc. are exemplified. Spring, leaf spring, rubber, shape memory alloy, etc. In this invention, the mechanical energy is stored outside the storage mechanism, and the force is human. For example, it is recorded that the rotary knob is rotated by pinching the rotary knob with a finger, whereby the coil spring is drawn into the power input shaft, and the external energy is stored to Coil spring. Japanese Patent Application Laid-Open No. 2002-84726 discloses a card-type generator, which is characterized in that it converts kinetic energy generated by its own movement into electrical energy, and the power generation mechanism is built into a card-shaped case And the power generation mechanism includes: a mechanical energy conversion mechanism that receives the foregoing kinetic energy and converts it into mechanical energy; a mechanical energy storage mechanism that stores the mechanical energy converted by the mechanical energy conversion mechanism; and a power generation mechanism that is The mechanical energy output from the mechanical energy storage mechanism is driven to generate electricity. An example of the mechanical energy storage mechanism is an elastic body (for example, a coil spring) that is deformed by the rotation of a rotary hammer and uses the deformation to store the mechanical energy. In addition, the kinetic energy used is kinetic energy generated by the carrier's walking and the like, and although it is indirect, it is human.

Moreover, the kinetic energy used is the kinetic energy of water flowing through the water channel.

That is, in the case where the extraction of renewable energy and the generation of electricity are processed in the same time series, the efficiency of power conversion is determined by the level of renewable energy and the conversion efficiency of the generator motor. The input of low renewable energy will cause the aforementioned problems. Obviously not. In addition, since there is no countermeasure to the sustainability of energy, natural discharge of power storage devices such as batteries cannot be avoided. Therefore, the present inventors have actively researched a mechanism that takes out the renewable energy and generates electricity in different time series, temporarily stores the renewable energy before generating electricity, and generates electricity after storing a certain amount of renewable energy. As a result, considering the accumulation of kinetic energy by a storage device equipped with a renewable energy source before the generator, the small kinetic energy and intermittent kinetic energy can be converted into large continuous kinetic energy and can be supplied to the generator. It was found that the environmental problems such as the low and intermittent generation of renewable energy sources, which are obstacles to the realization of renewable energy sources for civilian use, such as the wave power generation in the Gulf, can be overcome. That is, the present invention has been completed in view of the above circumstances, and provides a method for storing renewable energy temporarily before generating electricity by not taking out the renewable energy and generating electricity in the same time series, and storing the renewable energy as After a specific amount of power generation is effective, power generation is performed, thereby providing small and medium-sized power generation systems that can be practically used in people's livelihood environments with poor renewable energy environments, and potential energy storage devices applied to the power generation systems, and Elastic energy storage device.

儲存裝置3與發電裝置4由第2軸7連接。儲存裝置3之細節將於後文描述，利用經由第1軸5傳遞之第1動力而儲存位能，利用所儲存之位能產生第2動力。第2動力以第2軸7之旋轉運動而傳遞至發電裝置4。 發電裝置4將第2動力轉換為電力。作為發電裝置4之具體之構成可採用各種構成。作為一例，如圖1所示之發電裝置4具備：調速機41、發電部42、蓄電部43、及送電部44。 第2軸7係連接於調速機41及發電部42。調速機41將第2軸7之旋轉速度調整為適宜於發電之速度範圍內。作為調速機41，可使用例如離心調速機等。發電部42基於第2軸7之旋轉運動而產生電力。作為如此之發電部42之構成，可採用周知之各種構成。蓄電部43包含將在發電部42產生之電力蓄電之電池。送電部44將儲存於蓄電部43之電力以特定之電壓及電流供給至送電線。送電線既可為已存之送電網之一部分，亦可為在工場、高樓、或人居建物等之特定之建築物中在用途上特殊化而設置者。 儲存裝置3具備重物30，藉由利用第1動力使重物30朝反重力方向上升，而儲存與重物30之重量及上升之距離相應之位能。進而，儲存裝置3藉由使重物30朝重力方向下降，而利用所儲存之位能產生第2動力。如此般，儲存裝置3利用重物30之上下運動(升降運動、或朝重力方向之往復運動)而進行位能之儲存與利用。只要係發揮如此之機能者即可，儲存裝置3之構造並不被特別限定。 在圖1之例中，儲存裝置3具備：一對支柱32、第3軸33、軸構件34、捲繞器35、滑車36、及線體37。第3軸33其兩端由一對支柱32可轉動地軸支。軸構件34位於較第3軸33高之位置，其兩端由一對支柱32支持。捲繞器35係安裝於第3軸33，伴隨著第3軸33之旋轉而旋轉。滑車36由軸構件34可轉動地軸支。線體37其一端連接於捲繞器35，另一端連接於重物30。再者，線體37係掛於滑車36。作為線體37，可適宜地使用例如單線、複綫、或撚線之索或鏈條等。 在如此之構成中，若第3軸33朝某方向旋轉，則捲繞器35捲繞線體37而重物30上升。又，若重物30利用自身重量而下降，則捲繞於捲繞器35之線體37被放出，第3軸33朝相反之方向旋轉。以下，將捲繞線體37時之捲繞器35之旋轉方向稱為捲繞方向，將放出線體37時之捲繞器35之旋轉方向稱為放出方向。 儲存裝置3進一步包含：第1齒輪系38與第2齒輪系39。第1齒輪系38在線體37捲繞時，將第1軸5(軸5B)之旋轉運動傳遞至第3軸33。第2齒輪系39在線體37放出時，將第3軸33之旋轉運動傳遞至第2軸7。 在圖1之例中，第1齒輪系38包含彼此嚙合之齒輪38A、38B(第1齒輪)。齒輪38A安裝於第1軸5(軸5B)，以軸5B為軸而旋轉。齒輪38B安裝於第3軸33，以第3軸33為軸而旋轉。齒輪38A較齒輪38B為小徑。 而另一方面，第2齒輪系39包含彼此嚙合之齒輪39A、39B(第2齒輪)。齒輪39A安裝於第2軸7，以第2軸7為軸而旋轉。齒輪39B安裝於第3軸33，以第3軸33為軸而旋轉。齒輪39A較齒輪39B為小徑。 在本實施方式中，第2動力較第1動力大。又，第2動力至少超過發電裝置4之負載。此處，動力係例如每單位時間之工作量，相關於旋轉體而言可作為與轉矩和旋轉速度之積成比例之值而定義。 又，第1動力係基於不穩定之再生能源而產生者，根據再生能源之大小而變動。因此，可存在有第1動力暫時地較第2動力大之情形。在本實施方式中，所謂「第2動力較第1動力大」，並非係排除如此之暫時性第1動力超過第2動力之情形，而意圖為第1動力之時間上之平均值較第2動力小。 儲存裝置3進一步具備：控制裝置50、第1感測器51、及第2感測器52。第1感測器51配置於與重物30上下運動之區域接近之高處。第2感測器52配置於與重物30上下運動之區域接近之低處。第1感測器51在第1基準位置(後述之P1)中檢測出重物30。第2感測器52在較第1基準位置更靠重力方向之下方之第2基準位置(後述之P2)中檢測出重物30。 在本實施方式中，齒輪38A、39A具有可切換驅動方向與空轉方向之雙向性之離合器機構(後述之CL1、CL2)。該離合器機構係利用例如電磁性之控制來切換驅動方向與空轉方向者，係由控制裝置50控制。控制裝置50基於第1感測器51及第2感測器52之檢測信號，控制齒輪38A、39A之離合器機構。 圖2係概略性地顯示第1齒輪系38及第2齒輪系39的圖。由齒輪38A具備之第1離合器機構CL1、與齒輪39A具備之第2離合器機構CL2構成切換機構53。切換機構53切換第1狀態與第2狀態，前述第1狀態容許捲繞器35之朝捲繞方向之旋轉且不容許捲繞器35之朝放出方向之旋轉，前述第2狀態容許捲繞器35之朝放出方向之旋轉。 第1離合器機構CL1係可切換驅動方向與空轉方向之雙向性之離合器機構。亦即，齒輪38A作為雙向性離合器齒輪而發揮機能。驅動方向係在第1軸5與齒輪38B之間傳遞動力之齒輪38A之旋轉方向，空轉方向係在第1軸5與齒輪38B之間不傳遞動力之齒輪38A之旋轉方向。 而另一方面，第2離合器機構CL2雖然具有驅動方向與空轉方向，但是為無法切換該等方向之單向性之離合器機構。亦即，齒輪39A作為單向性離合器齒輪發揮機能。惟，作為第2離合器機構CL2，亦可使用雙向性之離合器機構。 在圖2中以實線表示之箭頭，表示位能儲存時之各齒輪之旋轉方向。而另一方面，以虛線表示之箭頭表示位能利用時之各齒輪之旋轉方向。 第1軸5在位能儲存時與利用時之任一者皆朝相同方向旋轉。在位能儲存時，以齒輪38A接受第1軸5之旋轉而朝實線箭頭之方向旋轉之方式，設定第1離合器機構CL1之驅動方向與空轉方向。接受該齒輪38A之旋轉，齒輪38B、第3軸33、齒輪39B、及齒輪39A朝以實線箭頭所示之方向旋轉。此時，以齒輪39A空轉，第2軸7不旋轉之方式，設定第2離合器機構CL2之驅動方向與旋轉方向。捲繞器35與第3軸33一起朝捲繞方向旋轉而線體37被捲繞，重物30上升。 在使用位能時，伴隨著重物30之下降，捲繞器35朝放出方向旋轉，第3軸33朝以虛線箭頭所示之方向旋轉。接受該第3軸33之旋轉，齒輪38B及齒輪39B朝以虛線箭頭所示之方向旋轉，藉此齒輪39A及齒輪39A亦朝以虛線箭頭所示之方向旋轉。 在位能利用時，利用控制裝置50之控制，第1離合器機構CL1之驅動方向與空轉方向逆轉。因此，由於齒輪38A空轉，故齒輪38A之旋轉不被傳遞至第1軸5。而另一方面，由於齒輪39A之旋轉與第2離合器機構CL2之驅動方向係一致，故接受齒輪39A之旋轉而第2軸7旋轉。接受第2軸7之旋轉(第2動力)，發電裝置4可發電。 又，在位能儲存時，有必要防止重物30之下降。在本實施方式中，利用第1軸5之負載(接納裝置2及變速機6之負載)、與第2軸7之負載(發電裝置4之負載)防止重物30之下降。亦即，在位能儲存時即便重物30意欲下降，此時之齒輪38A及齒輪39A之旋轉方向任一者皆與驅動方向一致。因此，第1軸5及第2軸7之負載同時作用，而可防止重物30之下降。 又，此處係顯示利用第1軸5及第2軸7之負載來防止重物30之下降之例，但亦可藉由設置其他之機構，來防止能源儲存時之重物30之下降。 繼之，針對儲存裝置3之動作使用圖3至圖5進行說明。 在位能儲存時，儲存裝置3被設定為上述之第1狀態。此時，利用經由第1軸5傳遞之第1動力，第1齒輪系38使第2軸33朝捲繞方向旋轉。相伴於此，捲繞器35捲繞線體37，如圖3所示般重物30上升。相應於重物30之上升距離之位能被儲存於儲存裝置3。 不久，如圖4所示般若重物30到達第1基準位置P1，則第1感測器51檢測出重物30。此時，第1感測器51將檢測信號輸出至控制裝置50。控制裝置50接受來自第1感測器51之檢測信號之輸入，控制切換機構53(主要是第1離合器機構CL1)，而將儲存裝置3切換至上述之第2狀態。 又，在第1基準位置P1中，重物30亦可位於再也無法上升之上止點。例如，可藉由配置規製重物30之上升之構件，來決定該上止點。在上止點處，重物30停止，相伴於此第3軸33及各齒輪亦停止。 若切換至第2狀態，則如圖5所示般，重物30利用自身重量而下降。亦即，捲繞器35及第3軸33朝放出方向旋轉。第3軸33之朝放出方向之旋轉經由第2齒輪系39被傳遞至第2軸7，而第2軸7旋轉。接受第2軸7之旋轉運動、亦即第2動力，發電裝置4產生電力。 其後，若重物30到達第2基準位置P2，則第2感測器52檢測出重物30。此時，第2感測器52將檢測信號輸出至控制裝置50。控制裝置50接受來自第2感測器52之檢測信號之輸入，控制切換機構53(主要是第1離合器機構CL1)，而將第2狀態切換至第1狀態。藉此，儲存裝置3再次利用第1動力儲存位能。 又，在第2基準位置P2中，重物30亦可位於再也無法下降之下止點。例如，可藉由配置規製重物30之下降之構件，來決定該下止點。或者是，線體37自捲繞器35全部放出時之重物30之位置可為下止點。在下止點處，重物30停止，相伴於此第3軸33及各齒輪亦停止。 如以上所述般，本實施方式之發電系統1反覆進行位能之儲存與利用。 自再生能源獲得之第1動力為不穩定，而未必經常獲得適宜於發電之值，亦存在有時會停止之情形。在先前之發電系統中，在來自接納裝置之動力低於發電裝置之負載之情形等時，存在有發電裝置不動作，而無法獲得電力之情形。在該情形下，接納裝置所產生之動力會浪費。 相對於此，在本實施方式之發電系統1中，即便在接納裝置2所產生之第1動力為小之情形下，亦可有效地活用該第1動力來發電。亦即，來自接納裝置2之第1動力暫時地在儲存裝置3中作為位能而被儲存。而後，若位能被充分地儲存，則儲存裝置3利用該位能產生超過發電裝置4之負載之第2動力。該第2動力由於相當於重物30利用自身重量下降時之能源，故極為穩定。 除此以外，亦可自本實施方式獲得已述之各種效果。 (第2實施方式) 針對第2實施方式進行說明。對於與第1實施方式相同或類似之要件賦予相同之符號，主要針對與第1實施方式之相異點予以敘述。 圖6係顯示本實施方式之發電系統1之概略性構成的圖。該發電系統1在儲存裝置3之構成方面與圖1所示者相異。亦即，儲存裝置3具備n個(n為2以上之整數)重物30、與n個滑車36。在圖6之例中n=3，儲存裝置3具備重物30A、30B、30C與滑車36A、36B、36C。惟，n亦可為其他值。 再者，在圖6之例中，線體37之一端連接於捲繞器35，另一端連接於終端器8。線體37係掛於滑車36A、36B、36C。滑車36A、36B、36C及終端器8係例如重力方向之高度為相同。 在重物30A、30B、30C之上表面，安裝有可轉動之滾軸9。於各滾軸9掛有線體37，藉此重物30A、30B、30C連接於線體37。 在如此之構成中，若利用第1動力使捲繞器35朝捲繞方向旋轉，則線體37被捲繞器35捲繞而重物30A、30B、30C朝重力方向上升。藉此，相應於重物30A、30B、30C之重量與重物30A、30B、30C上升之距離的位能被儲存。 而另一方面，若重物30A、30B、30C利用自身重量而朝重力方向下降，則捲繞器35朝放出方向旋轉，線體37自捲繞器35被放出，而第3軸33旋轉。第3軸33之朝放出方向之旋轉經由第2齒輪系39被傳遞至第2軸7，而第2軸7旋轉。接受第2軸7之旋轉運動、亦即第2動力，發電裝置4產生電力。 又，雖未在圖6中顯示，但儲存裝置3與第1實施方式相同地具備第1感測器51、第2感測器52、及控制裝置50。第1感測器51及第2感測器52只要檢測出例如重物30A、30B、30C之任一者即可。 在本實施方式之構成中，可使複數個重物30分散地儲存位能。因此，即便減小重物30之上升距離，亦可儲存充分之位能。 假設，在圖6之例中，在重物30A、30B、30C各者之重量與圖1所示之重物30之重量為相同之情形下，儲存相同位能時之上升距離在圖6之例中為圖1之1/3即可。 其他，可自本實施方式獲得各種適宜之效果。 可對以上所說明之第1及第2實施方式之構成施加各種變形。例如，在各實施方式中所揭示之構成可適宜地組合。在不脫離發明之要旨之範圍內而變化之方式，均包含於申請專利範圍所記載之發明及其均等之範圍內。 例如，儲存裝置3亦可具備引導重物30之上下運動之構件。若設置如此之構件，則可穩定地使重物30上下運動。 可行的是，儲存裝置3具備將來自接納裝置2之第1動力保持原樣傳遞至發電裝置4的機構，而可切換該機構與儲存位能之機構。該情形下，在例如吹有強風時等再生能源充分強之情形下，可利用第1動力來發電。 控制裝置50切換第1狀態與第2狀態之控制方式並不限定於上述者。例如，可行的是，在第1感測器51檢測出重物30而切換至第2狀態之後，在經過一定時間時切換至第1狀態。在該情形下，無需第2感測器52。又，可行的是，在第2感測器52檢測出重物30而切換至第1狀態之後，在經過一定時間時切換至第2狀態。在該情形下，無需第1感測器51。此外，亦可以每一定時間切換第1狀態與第2狀態。在此情形下，無需第1感測器51及第2感測器52此二者。另外，可行的是，計數捲繞器35等之旋轉數，根據該計數值而切換第1狀態與第2狀態。可採用其他各種之控制方式。 (第3實施方式) 圖7係顯示第3實施方式之發電系統201之概略性構成的圖。該發電系統201具備：再生能源接納裝置202(以下稱為接納裝置202)、儲存裝置203、及發電裝置204。 接納裝置202接納再生能源而產生第1動力。再生能源可利用例如，風力、海等之水面上下運動之力即波力、水壩之放水或河川中水流動之力即水力等利用流體之流動而產生之各種能源。又，作為再生能源，亦可利用潮汐之力即潮力、或利用地熱而產生之水蒸氣等。再生能源亦有被稱為可再生能源之情形。該等再生能源接納裝置本身，本領域技術人員例如可自日本特開2015-17614號公報及日本特開2015-17622號公報等知悉。又，本發明之再生能源接納裝置當然並不限定於日本特開2015-17614號公報及日本特開2015-17622號公報所記載之裝置。 接納裝置202與儲存裝置203由第1軸205連接。在圖7之例中，接納裝置2所產生之第1動力經由第1軸205傳遞至儲存裝置3。 細節將在第4至第6實施方式中於後文描述，接納裝置202作為接納再生能源而產生第1動力之機構可採用各種機構。例如在再生能源為風力之情形下，接納裝置202具備：葉片，其接納風力而旋轉；及動力產生機構，其伴隨著該葉片之旋轉而使第1軸205旋轉。又，在再生能源為波力之情形下，接納裝置202具備：浮體，其與水面一起上下運動；及動力產生機構，其伴隨著該浮體之上下運動而使第1軸205旋轉。此外，在再生能源為水力之情形下，接納裝置202具備：水輪機，其接納水力而旋轉；及動力產生機構，其伴隨著該水輪機之旋轉而使第1軸205旋轉。 上述動力產生機構之構成並非係特別地限定者。例如，在風力或水力之情形下，可包含將葉片或水輪機之旋轉運動傳遞至第1軸205之齒輪系。又，在波力之情形下，可包含：齒條，其伴隨著浮體之上下運動而往復運動；及齒輪系，其嚙合於該齒條並伴隨著齒條之往復運動而旋轉而使第1軸205旋轉。 葉片或水輪機之旋轉運動及浮體之上下運動在轉換為纜線之往復運動之後，可轉換為第1軸205之旋轉運動。作為上述纜線，例如，可採用下述構造，即：包含中空之外部纜線與通過該外部纜線之內部之內部纜線，且內部纜線在外部纜線之內部往復運動。藉由使外部纜線及內部纜線具有柔軟性，即便在使內部纜線之往復運動轉換為旋轉運動之機構設置於遠離葉片、水輪機、或浮體之設置位置的位置，亦可將兩者容易地連接。 在圖7之例中，在接納裝置202與儲存裝置203之間介設有變速機206。再者，第1軸205包含：軸205A，其連接接納裝置202與變速機206；及軸205B，其連接變速機206與儲存裝置203。在該構成中，軸205A利用接納裝置202之第1動力而旋轉。變速機206使軸205A之旋轉速度變速(增速或減速)，而使軸205B以變速後之旋轉速度旋轉。變速機206之增速比或減速比可考量以接納裝置2可獲得之旋轉數及轉矩，或儲存裝置3所需之旋轉數及轉矩等而適宜地設定。 儲存裝置203與發電裝置204由第2軸207連接。儲存裝置203之細節將於後文描述，利用經由第1軸205傳遞之第1動力儲存彈性能，利用所儲存之彈性能產生第2動力。第2動力以第2軸207之旋轉運動而傳遞至發電裝置204。 發電裝置204將第2動力轉換為電力。作為發電裝置204之具體之構成可採用各種構成。作為一例，如圖7所示之發電裝置204具備：調速機241、發電部242、蓄電部243、及送電部244。 第2軸207係連接於調速機241及發電部242。調速機241將第2軸207之旋轉速度調整為適宜於發電之速度範圍內。作為調速機241，可使用例如離心調速機等。發電部242基於第2軸207之旋轉運動而產生電力。作為如此之發電部242之構成，可採用周知之各種構成。蓄電部243包含將在發電部242產生之電力蓄電之電池。送電部244將儲存於蓄電部243之電力以特定之電壓及電流供給至送電線。送電線既可為已存之送電網之一部分，亦可為在工場、高樓、或人居建物等之特定之建築物中在用途上特殊化而設置者。 儲存裝置203具備彈性體，藉由利用第1動力使彈性體彈性變形而儲存與彈性體之彈性係數及變形量相對應之彈性能。進而，在彈性體解除彈性變形時，儲存裝置203利用儲存於彈性體之彈性能產生第2動力。如此般，儲存裝置203藉由彈性體之彈性變形與其解除來進行彈性能之儲存與利用。只要係發揮如此之機能者即可，儲存裝置203之構造並不被特別限定。 在本實施方式中，第2動力較第1動力大。又，第2動力至少超過發電裝置204之負載。此處，動力係例如每單位時間之工作量，相關於旋轉體而言可作為與轉矩和旋轉速度之積成比例之值而定義。 又，第1動力係基於不穩定之再生能源而產生者，根據再生能源之大小而變動。因此，可存在有第1動力暫時地較第2動力大之情形。在本實施方式中，所謂「第2動力較第1動力大」，並非係排除如此之暫時性第1動力超過第2動力之情形，而意圖為第1動力之時間上之平均值較第2動力小。 圖8及圖9係顯示儲存裝置203之一構成例的圖。該例中之儲存裝置203如圖8所示般，具備：凸輪230、第3軸231、第1齒輪系232、及第2齒輪系233。再者，儲存裝置203如圖9所示般具備：彈性體234、軌道235、擋止件236、及滑件237。 第1齒輪系232將第1軸205(軸205B)之旋轉運動傳遞至第3軸231。第2齒輪系233將第3軸231之旋轉運動傳遞至第2軸207。 在圖8之例中，第1齒輪系232包含彼此嚙合之齒輪232A、232B(第1齒輪)。齒輪232A安裝於第1軸205(軸205B)，以軸205B為軸而旋轉。齒輪232B安裝於第3軸231，以第3軸231為軸而旋轉。齒輪232A較齒輪232B為小徑。齒輪232A具有例如單向性之離合器機構，在軸205B利用第1動力朝某方向旋轉時將該旋轉傳遞至齒輪232B，在朝其他方向旋轉時為空轉。 而另一方面，第2齒輪系233包含彼此嚙合之齒輪233A、233B(第2齒輪)。齒輪233A安裝於第2軸207，以第2軸207為軸而旋轉。齒輪233B安裝於第3軸231，以第3軸231為軸而旋轉。齒輪233A較齒輪233B為小徑。 凸輪230安裝於第3軸231，以第3軸231為軸而旋轉。例如，凸輪230係曲面之圓周面與第3軸231之距離根據旋轉角度而變化之圓板凸輪。 彈性體234包含由例如帶狀之構件構成之環體238。環體238可在半徑方向上彈性變形。環體238可以例如彈簧用鋼材等之金屬材料或橡膠等而形成。在圖9之例中，彈性體234包含5個環體238。惟，彈性體234所含之環體238之數目可為4個以下，亦可為6個以上。環體238在例如未彈性變形之自然狀態下為正圓形。惟，環體238在自然狀態下亦可為橢圓形或多角形狀等之其他形狀。又，環體238之具體之材料、壁厚、圓周方向之寬度、及直徑等，可考量所要求之彈性力、設置空間、及製造成本等而適宜地決定。 彈性體234替代環體238亦可包含例如U字型之構件、V字型之構件、或將2個U字型之構件結合之環狀之構件。該等之構件與環體238相同地，可以鋼材等之金屬材料而形成。 各環體238介以滑件237安裝於軌道235。滑件237沿軌道235滑動自如。各環體238沿軌道235直線狀地並排。相鄰之環體238之外周面係彼此接觸。例如，藉由在軌道235與滑件237之接觸部配置滾軸或滾珠，而可減小因摩擦導致之損耗。如此之滾軸或滾珠可設置於軌道235及滑件237之任一者。 凸輪230之外周面係與圖9之左端之環體238之外周面接觸。圖9之右端之環體238之外周面係與擋止件236接觸。擋止件236、軌道235、及第3軸231之位置關係係固定，不因凸輪230之旋轉而變化。 繼之，針對儲存裝置203之動作使用圖9至圖12進行說明。 若軸205B利用第1動力旋轉，則齒輪232A、232B、第3軸231、凸輪230、齒輪233A、233B、第2軸207旋轉。此時，相應於凸輪230之旋轉角度，各環體238反覆進行彈性變形(彈性能之儲存)與其解除(彈性能之利用)。 圖10顯示彈性能儲存時的狀態。在凸輪230之外周面接觸於環體238之位置與第3軸231之間之距離增加之期間，凸輪230將各環體238朝向擋止件236按壓。藉此，各環體238朝圖中之以箭頭所示之方向彈性變形而儲存彈性能。 又，在彈性能儲存時，彈性體234按壓凸輪230之力較軸205B之負載(接納裝置202及變速機206之負載)、與第2軸207之負載(發電裝置204之負載)之合計更小。因此，凸輪230不會逆向旋轉。或，可行的是，以在彈性能儲存時凸輪230不逆向旋轉之方式將另外之機構設置於儲存裝置203。 不久，如圖11所示般，若凸輪230之外周面接觸於環體238之位置與第3軸231之間之距離達到最大距離，則彈性能之儲存量成為最大。 圖12係顯示彈性能利用時之狀態。在凸輪230之外周面接觸於環體238之位置與第3軸231之間之距離減少之期間，由於各環體238之彈性變形解除，故凸輪230被朝圖中之以箭頭所示之方向按壓。亦即，儲存於彈性體234之彈性能被利用。 此時，凸輪230除了因第1動力而旋轉外，還利用被彈性體234按壓之力而旋轉。伴隨著如此之凸輪230之旋轉而產生之動力相當於上述之第2動力。該第2動力經由第2軸207被傳遞至發電裝置204，發電裝置204發電。其後，若凸輪230之外周面接觸於環體238之位置與第3軸231之間之距離達到最低距離，則再次開始彈性能之儲存。 又，在彈性能儲存時第2軸207亦旋轉，但由於旋轉速度及轉矩小，故發電裝置204不發電。或即便發電，亦僅產生極小之電力。一般而言，所產生之電力愈大則發電裝置之負載愈大。因此，在彈性能儲存時之發電裝置204之負載變為極小。 自其他之觀點而言，以在彈性能儲存時彈性體234彈性變形且發電裝置204不發電之方式決定變速機206之變速比。 亦即，使軸205B旋轉之轉矩N1，較利用發電裝置204進行發電所需之轉矩N2小(N1＜N2)。或，經由軸205B被傳遞之第1動力W1較利用發電裝置204進行發電所需之第3動力W3小，且與利用儲存裝置203進行彈性能之儲存所需之第4動力W4等同或為其以上(W4≦W1＜W3)。又，在彈性能利用時於儲存裝置203產生之第2動力W2係與第3動力W3等同或為其以上(W3≦W2)。 如以上所述般，本實施方式之發電系統201反覆進行彈性能之儲存與利用。自再生能源獲得之第1動力係不穩定，而未必經常獲得適宜於發電之值，而存在有時會停止之情形。在先前之發電系統中，在來自接納裝置之動力低於發電裝置之負載之情形等時，存在有發電裝置不動作，而無法獲得電力之情形。在該情形下，接納裝置所產生之動力會浪費。 相對於此，在本實施方式之發電系統201中，即便在接納裝置202產生之第1動力為小之情形下，亦可有效地活用該第1動力來發電。亦即，來自接納裝置202之第1動力暫時在儲存裝置203中作為彈性能而被儲存。而後，若彈性能被充分地儲存，則儲存裝置203利用該彈性能產生超過發電裝置204之負載之第2動力。該第2動力由於相當於彈性體234釋放彈性變形時之能源，故極為穩定。 除此以外，亦可自本實施方式獲得已述之各種效果。 (第4實施方式) 針對第4實施方式進行說明。在本實施方式中，揭示第3實施方式之接納裝置202之具體例。對於與第3實施方式相同或類似之要件賦予相同之符號，主要針對與第3實施方式之相異點予以敘述。 圖13係顯示第4實施方式之發電系統201之主要部分構成的圖。此處，係例示第3實施方式之接納裝置202接受波力而產生第1動力之構成。接納裝置202具備：浮體220、齒條221、及齒輪222。 浮體220漂浮於例如海或湖等之水面WF。浮體220根據波浪所導致之水面WF之位置變化而上下運動。齒條221係固定於浮體220。齒條221具有在浮體220之上下運動之方向上直線狀地並排之刃列221a。齒輪222係嚙合於刃列221a。齒輪222可以軸205A為軸而旋轉。 伴隨著浮體220之上下運動，齒條221上下運動。齒輪222具備例如單向性之離合器機構，將齒條221之上升時之旋轉傳遞至軸205A，而不將齒條221之下降時之旋轉傳遞至軸205A。該情形下，齒條221之上升時之軸205A之旋轉運動相當於第1動力。與此相反，齒輪222亦可將齒條221之下降時之旋轉傳遞至軸205A。該情形下，齒條221之下降時之軸205A之旋轉運動相當於第1動力。進而作為其他例，可行的是，藉由使用複數個齒輪，將齒條221之上升時與下降時之二者之旋轉傳遞至軸205A。該情形下，齒條221之上升時及下降時之二者之軸205A之旋轉運動相當於第1動力。 又，在圖13中，係顯示浮體220與齒條221被固定之例。然而，浮體220與齒條221亦可由上述之內部纜線及外部纜線連接。該情形下，浮體220及儲存裝置203等之設置位置之自由度提高。 (第5實施方式) 針對第5實施方式進行說明。在本實施方式中，揭示第3實施方式之接納裝置202之又一具體例。對於與第3實施方式相同或類似之要件賦予相同之符號，主要針對與第3實施方式之相異點予以敘述。 圖14係顯示第5實施方式之發電系統201之主要部分構成的圖。此處，係例示第3實施方式之接納裝置202接受風力而產生第1動力之構成。接納裝置202具備葉片223。儲存裝置203、發電裝置204、及變速機206係收容於由支柱300支持於高處之吊艙301內。發電裝置204之一部分、例如蓄電部243或送電部244亦可設置於吊艙301之外部。在圖14之例中，彈性體234之各環體238及擋止件係在上下方向(重力方向，支柱300之延伸方向)並排。 葉片223可以軸205A為軸而旋轉。在該構成中，在葉片223接納風而旋轉時，軸205A旋轉。該軸205A之旋轉運動相當於第1動力。 又，在圖14中，顯示葉片223之旋轉運動直接傳遞至軸205A之例。然而，亦可在葉片223與軸205A之間介設上述之內部纜線及外部纜線。該情形下，設置例如將葉片223之旋轉運動轉換為內部纜線之往復運動之機構與將內部纜線之往復運動轉換為軸205A之旋轉運動之機構。若係如此之構成，則儲存裝置203及發電裝置204可配置於吊艙301之外部。 (第6實施方式) 針對第6實施方式進行說明。在本實施方式中，揭示第3實施方式之接納裝置202之另一具體例。對於與第3實施方式相同或類似之要件賦予相同之符號，主要針對與第3實施方式之相異點予以敘述。 圖15係顯示第6實施方式之發電系統201之主要部分構成的圖。此處，係例示第3實施方式之接納裝置202接受在河川等中流動之水的水力而產生第1動力之構成。接納裝置202具備下方浸入在河川等流動之流水R的水輪機224。水輪機224接受流水R之力，並以軸205A為軸而旋轉。該軸205A之旋轉運動相當於第1動力。 又，在圖15中，顯示水輪機224之旋轉運動直接傳遞至軸205A之例。然而，亦可在水輪機224與軸205A之間介設上述之內部纜線及外部纜線。該情形下，設置例如將水輪機224之旋轉運動轉換為內部纜線之往復運動之機構與將內部纜線之往復運動轉換為軸205A之旋轉運動之機構。若係如此之構成，則水輪機224及儲存裝置203等之設置位置之自由度提高。 (第7實施方式) 針對第7實施方式進行說明。在本實施方式中，揭示儲存裝置203之其他例。對於與第3實施方式相同或類似之要件賦予相同之符號，主要針對與第3實施方式之相異點予以敘述。 圖16係顯示第7實施方式之儲存裝置203之概略性構成的圖。該儲存裝置203具備：齒輪330(第1齒輪)、齒輪331(第2齒輪)、齒輪332(第3齒輪)、齒條333、可動構件334、感測器335、及控制裝置336。再者，儲存裝置203與第3實施方式相同地具備：軌道235、擋止件236、彈性體234、及滑件237。在圖16之例中，彈性體234包含3個環體238。惟，環體238之數目及形狀並無特別限定。 齒輪330可以軸205B為軸而旋轉。齒輪331可以第2軸207為軸而旋轉。齒輪332可以軸337為軸而旋轉。 齒條333具有直線狀地排列之刃列333a。可動構件334係連接於齒條333之一端。再者，可動構件334係與配置於圖中之左端之環體238之外周面接觸。 齒輪332係與齒輪330、齒輪331、及刃列333a嚙合。伴隨著齒輪332之旋轉，齒條333及可動構件334朝靠近擋止件236之方向與遠離擋止件236之方向往復運動。 在本實施方式中，齒輪330具有可切換驅動方向與空轉方向之雙向性之第1離合器機構CL1。該第1離合器機構CL1係利用例如電磁性控制來切換驅動方向與空轉方向者，係由控制裝置336來控制。 例如，感測器335檢測出齒條333或可動構件334達到第1基準位置及第2基準位置。第1基準位置係例如賦予齒條333之標記M1與感測器335正對之位置。第2基準位置係例如賦予齒條333之標記M2與感測器335正對之位置。感測器335在檢測出標記M1、M2時輸出檢測信號。例如，感測器335係光學性地檢測標記M1、M2之光學感測器。感測器335亦可為磁性地檢測標記M1、M2之磁性感測器等其他種類之感測器。 控制裝置336基於感測器335之檢測信號控制第1離合器機構CL1。亦即，齒輪330作為雙向性離合器齒輪發揮機能。在第1離合器機構CL1中，驅動方向係在軸205B與齒輪332之間傳遞動力之齒輪330之旋轉方向，空轉方向係在軸205B與齒輪332之間不傳遞動力之齒輪330之旋轉方向。 又，在本實施方式中，齒輪331具有驅動方向與空轉方向，但是具有無法切換該等方向之單向性之第2離合器機構CL2。亦即，齒輪331作為單向性離合器齒輪發揮機能。惟，作為第2離合器機構CL2，亦可使用雙向性之離合器機構。第2離合器機構CL2中，驅動方向係在第2軸207與齒輪332之間傳遞動力之齒輪331之旋轉方向，空轉方向係在第2軸7與齒輪332之間不傳遞動力之齒輪331之旋轉方向。 第1離合器機構CL1與第2離合器機構CL2構成切換機構340。切換機構340係切換容許彈性體234之彈性變形之第1狀態、與釋放彈性體234之彈性變形之第2狀態。 在圖16中以實線所示之箭頭表示彈性能儲存時之各齒輪之旋轉方向。另一方面，以虛線表示之箭頭顯示彈性能利用時之各齒輪之旋轉方向。 軸205B在彈性能儲存時與利用時之任一者皆朝相同方向旋轉。在彈性能儲存時，以齒輪330接受軸205B之旋轉而朝實線箭頭之方向旋轉之方式，設定第1離合器機構CL1之驅動方向與空轉方向。接受該齒輪330之旋轉，齒輪332、齒輪331、及齒輪331朝以實線箭頭所示之方向旋轉。此時，以齒輪331空轉，第2軸207不旋轉之方式，設定第2離合器機構CL2之驅動方向與旋轉方向。伴隨著齒輪332之旋轉，齒條333及可動構件334朝向擋止件236移動。進而，被可動構件334按壓而各環體238彈性變形。 在彈性能利用時，可動構件334及齒條333被彈性體234朝遠離擋止件236之方向按壓，藉此齒輪332朝以虛線箭頭所示之方向旋轉。接受該齒輪332之旋轉，齒輪330及齒輪331朝以虛線箭頭所示之方向旋轉。 在彈性能利用時，利用控制裝置336之控制，第1離合器機構CL1之驅動方向與空轉方向逆轉。因此，由於齒輪330空轉，故齒輪330之旋轉不傳遞至軸205B。而另一方面，由於齒輪331之旋轉與第2離合器機構CL2之驅動方向係一致，故接受齒輪331之旋轉而第2軸207旋轉。接受第2軸207之旋轉(第2動力)，發電裝置204可發電。 又，在彈性能儲存時，有必要防止彈性體234之彈性變形之釋放。在本實施方式中，利用軸205B之負載(接納裝置202及變速機206之負載)、與第2軸207之負載(發電裝置204之負載)防止彈性體234之彈性變形之釋放。亦即，在彈性能儲存時即便彈性體234意欲將可動構件334及齒條333朝遠離擋止件236之方向按壓，此時之齒輪330及齒輪331之旋轉方向任一者皆與驅動方向一致。因此，軸205B及第2軸207之負載同時作用，而可防止可動構件334及齒條333之移動。 又，此處係顯示利用軸205B及第2軸207之負載來防止彈性體234之彈性變形之釋放之例，但亦可藉由設置其他之機構，來防止能源儲存時之彈性變形之釋放。 繼之，針對儲存裝置203之動作使用圖16至圖19進行說明。 在彈性能儲存時，儲存裝置203被設定為上述之第1狀態。此時，如圖17所示般，齒輪330、332利用經由軸205B被傳遞之第1動力而旋轉，齒條333及可動構件334朝向擋止件236移動。相伴於此，各環體238彈性變形，相應於該彈性變形之彈性能被儲存於儲存裝置203。 不久，如圖18所示般若感測器335正對標記M1，則感測器335輸出檢測信號。控制裝置336接受來自感測器335之檢測信號之輸入，控制切換機構340(主要是第1離合器機構CL1)，而將儲存裝置203切換至上述之第2狀態。 若切換至第2狀態，則如圖19所示般，藉由彈性體234之彈性變形之釋放而可動構件334及齒條333被按壓，可動構件334及齒條333朝遠離擋止件236之方向移動。接受此時之齒輪332之旋轉而齒輪331旋轉，進而齒輪331之旋轉被傳遞至第2軸207，而第2軸207旋轉。接受第2軸207之旋轉運動、亦即第2動力，發電裝置204產生電力。 其後，如圖16所示般，若感測器335正對標記M2，則感測器335輸出檢測信號。控制裝置336接受來自感測器335之檢測信號之輸入，控制切換機構340(主要是第1離合器機構CL1)，而將儲存裝置203切換至上述之第1狀態。藉此，儲存裝置203再次利用第1動力儲存彈性能。 如以上所述般，在本實施方式之發電系統201中亦然，反覆進行彈性能之儲存與利用。本實施方式所揭示之儲存裝置203之構成可應用於第4至第6實施方式之任一者。 對以上所說明之第3至第7實施方式之構成可施加各種變化。例如，在各實施方式中所揭示之構成可適宜地組合。在不脫離發明之要旨之範圍內而變化之方式，均包含於申請專利範圍所記載之發明及其均等之範圍內。 例如，在各實施方式中，揭示儲存裝置203藉由壓縮彈性體234而儲存彈性能之例。然而，儲存裝置203既可藉由伸長彈性體234儲存彈性能，亦可連續地進行壓縮與伸長來儲存。 可行的是，儲存裝置203具備將來自接納裝置202之第1動力保持原樣傳遞至發電裝置204的機構，而可切換該機構與儲存彈性能之機構。該情形下，在例如吹有強風時等再生能源充分強之情形下，可利用第1動力來發電。 在第7實施方式中，控制裝置336切換第1狀態與第2狀態之控制方式並不限定於上述者。例如，可行的是，在感測器335檢測出標記M1而切換至第2狀態之後，在經過一定時間時切換至第1狀態。在該情形下，無需標記M2之檢測。又，可行的是，在感測器335檢測出標記M2而切換至第1狀態之後，在經過一定時間時切換至第2狀態。在該情形下，無需標記M1之檢測。此外，亦可以每一定時間切換第1狀態與第2狀態。在該情形下，無需感測器335。另外，可行的是，計數齒輪332等之旋轉數，根據該計數值而切換第1狀態與第2狀態。可採用其他各種之控制方式。 儲存裝置203中使彈性體234彈性變形之方式並不限定於使用凸輪230或齒條333者。例如，亦可利用滾珠螺桿機構，其包含伴隨著軸205B之旋轉而旋轉之螺桿、與經由滾珠旋入該螺桿之螺帽。亦即，在該滾珠螺桿機構中，若伴隨著螺帽之移動使彈性體234壓縮或伸長，則可使彈性體34彈性變形。 [產業上之可利用性] 根據本發明，在利用先前之再生能源之發電系統存在之眾多問題之中，至少可解決因能源接納部之動作開始閾值之問題、發電系統之閾值之問題、發電效率之問題、發電之非持續性而導致之電池等之蓄電裝置之蓄電性能之問題。 根據本發明，可以比較簡單之構成提高發電效率，而可實現廉價且高效率之發電系統。此事實毫無疑問在提高系統之性能且對民生用之風力發電及波力發電方面作出巨大貢獻。 進而，本發明之位能儲存裝置或彈性能儲存裝置除了與再生能源接納裝置之組合之外，亦可與人力或起重車此般外部動力組合，而作為偏僻地域用、緊急用之發電裝置使用。亦即，在如叢林之中之偏僻地域，可藉由替代再生能源、將人力合力藉而儲存位能或彈性能並使其發電，在緊急時，可藉由利用如起重車之外部之力提升裝置之重物，而施加位能或彈性能，藉而提供長時間之穩定之發電。 換言之，在本說明書所記載之發明中，與申請專利範圍所記載之發明一起皆包含：「具備儲存裝置與發電裝置之發電系統，前述儲存裝置係利用外部動力之第1動力儲存位能或彈性能，且利用所儲存之位能或彈性能產生較前述第1動力大之第2動力者，前述發電裝置係將前述第2動力轉換為電力者」、及「發電系統用位能儲存裝置或彈性能儲存裝置，其係利用外部動力即第1動力儲存位能或彈性能，並利用所儲存之位能或彈性能產生較前述第1動力大之第2動力，且將其用於發電者」。For several implementations, The description will be made with reference to the drawings.  In the first and second embodiments, The invention discloses a power generation system having a storage device capable of storing potential energy. In the third to seventh embodiments, The invention discloses a power generation system having a storage device for storing elastic energy.  (First Embodiment) FIG. 1 is a diagram showing a schematic configuration of a power generation system 1 according to a first embodiment. The power generation system 1 includes: Renewable energy receiving device 2 (hereinafter referred to as receiving device 2), Storage device 3. And power generation device 4.  The receiving device 2 receives the renewable energy and generates a first power. Renewable energy sources such as wind power, The force of the water moving up and down the surface is the wave force, The power of dam flood discharge or river flow is the various energy sources such as hydraulic power generated by the flow of fluid. also, As a renewable energy, You can also use the power of the tide Or use water vapor generated by geothermal. Renewable energy is also referred to as renewable energy. The renewable energy receiving devices themselves, Those skilled in the art can know from, for example, Japanese Patent Laid-Open No. 2015-17614 and Japanese Patent Laid-Open No. 2015-17622. also, The renewable energy receiving device of the present invention is of course not limited to the devices described in Japanese Patent Application Laid-Open No. 2015-17614 and Japanese Patent Application Laid-Open No. 2015-17622.  The receiving device 2 and the storage device 3 are connected by a first shaft 5. In the example of Figure 1, The first power generated by the receiving device 2 is transmitted to the storage device 3 through the first shaft 5.  As the mechanism that receives the renewable energy and generates the first power, the receiving device 2 can adopt various mechanisms. For example, when the renewable energy is wind power, The receiving device 2 has: blade, It receives wind and rotates; And power generation mechanism, It rotates the first shaft 5 with the rotation of the blade. also, When renewable energy is wave power, The receiving device 2 has: Floating body, It moves up and down with the water surface; And power generation mechanism, It rotates the first shaft 5 along with the up and down movement of the floating body. In addition, Where renewable energy is hydro, The receiving device 2 has: Water turbine, It receives water and rotates; And power generation mechanism, It rotates the first shaft 5 with the rotation of the water turbine.  The configuration of the power generation mechanism is not particularly limited. E.g, In the case of wind or water, It may include a gear train transmitting a rotary motion of a blade or a turbine to the first shaft 5. also, In the case of wave force, May include racks, It reciprocates with the up and down movement of the floating body; And gear trains, It engages with the rack and rotates with the reciprocating motion of the rack to rotate the first shaft 5.  After the rotary motion of the blade or the turbine and the up and down motion of the floating body are converted into the reciprocating motion of the cable, It can be converted into the rotary motion of the first axis 5. As the above cable, E.g, The following constructions can be used, which is: Including a hollow external cable and an internal cable passing through the interior of the external cable, And the inner cable reciprocates inside the outer cable. By making the outer and inner cables flexible, Even if the mechanism that converts the reciprocating motion of the internal cable into a rotary motion is installed away from the blade, Water turbine, Or the position of the floating body, The two can also be easily connected.  In the example of Figure 1, A transmission 6 is interposed between the receiving device 2 and the storage device 3. Furthermore, The first axis 5 contains: Axis 5A, It connects the receiving device 2 and the transmission 6; And shaft 5B, It connects the transmission 6 and the storage device 3. In this constitution, The shaft 5A is rotated by the first power of the receiving device 2. The speed changer 6 changes the speed of the shaft 5A (increasing or decreasing), The shaft 5B is rotated at the rotation speed after the speed change. The speed increase ratio or speed reduction ratio of the transmission 6 may be considered to accept the number of rotations and torque that the device 2 can obtain, Or, the number of rotations and torque required for the storage device 3 are appropriately set.  The storage device 3 and the power generation device 4 are connected by a second shaft 7. The details of the storage device 3 will be described later, Potential energy is stored using the first power transmitted through the first shaft 5, Using the stored position can generate a second power. The second power is transmitted to the power generating device 4 by the rotational motion of the second shaft 7.  The power generation device 4 converts the second power into electric power. Various specific configurations can be adopted as the specific configuration of the power generating device 4. As an example, The power generating device 4 shown in FIG. 1 includes: Speed governor 41, Power generation section 42, Power storage unit 43, And power transmission unit 44.  The second shaft 7 is connected to the speed governor 41 and the power generation section 42. The governor 41 adjusts the rotation speed of the second shaft 7 to a speed range suitable for power generation. As a governor 41, For example, a centrifugal governor can be used. The power generation unit 42 generates electric power based on the rotational movement of the second shaft 7. As a configuration of such a power generation section 42, Various well-known structures can be adopted. The power storage unit 43 includes a battery that stores power generated by the power generation unit 42. The power transmission unit 44 supplies the power stored in the power storage unit 43 to the power transmission line at a specific voltage and current. The transmission line can be part of the existing transmission grid, Can also be in the workshop, Tall buildings, It is set up in a special building such as a residential building or the like for its purpose.  The storage device 3 includes a weight 30, By using the first power to raise the weight 30 in the anti-gravity direction, The potential energy corresponding to the weight of the weight 30 and the rising distance is stored. and then, The storage device 3 lowers the weight 30 in the direction of gravity, And using the stored position can generate a second power. So so The storage device 3 uses the weight 30 to move up and down (elevating movement, (Or reciprocating in the direction of gravity) for storage and utilization of potential energy. As long as it is such a function, The structure of the storage device 3 is not particularly limited.  In the example of Figure 1, The storage device 3 includes: A pair of pillars 32, 3rd axis 33, Shaft member 34, Winder 35, Block 36, 和 线 体 37。 And the line body 37. The third shaft 33 is rotatably supported at both ends by a pair of pillars 32. The shaft member 34 is located higher than the third shaft 33, Its ends are supported by a pair of pillars 32. The winder 35 is mounted on the third shaft 33, It rotates in accordance with the rotation of the third shaft 33. The pulley 36 is rotatably supported by a shaft member 34. One end of the wire body 37 is connected to the winder 35, The other end is connected to the weight 30. Furthermore, The thread body 37 is hung on the pulley 36. As the thread body 37, Appropriately used, such as single line, Double line, Or twisted cables or chains.  In such a constitution, If the third axis 33 rotates in a certain direction, Then, the winder 35 winds the wire body 37 and the weight 30 rises. also, If the weight 30 is lowered by its own weight, The wire body 37 wound around the winder 35 is released, The third shaft 33 rotates in the opposite direction. the following, The rotation direction of the winder 35 when winding the wire body 37 is referred to as a winding direction. The direction of rotation of the winder 35 when the thread body 37 is released is referred to as a release direction.  The storage device 3 further includes: The first gear train 38 and the second gear train 39. When the first gear train 38 is wound on the wire body 37, The rotation of the first shaft 5 (shaft 5B) is transmitted to the third shaft 33. When the second gear train 39 is released from the wire body 37, The rotation of the third shaft 33 is transmitted to the second shaft 7.  In the example of Figure 1, The first gear train 38 includes gears 38A, 38B (first gear). Gear 38A is mounted on the first shaft 5 (shaft 5B), Rotate around the shaft 5B. Gear 38B is mounted on the third shaft 33, The third shaft 33 is rotated as an axis. Gear 38A has a smaller diameter than gear 38B.  On the other hand, The second gear train 39 includes gears 39A, 39B (second gear). Gear 39A is mounted on the second shaft 7, Rotates around the second shaft 7. Gear 39B is mounted on the third shaft 33, The third shaft 33 is rotated as an axis. Gear 39A has a smaller diameter than gear 39B.  In this embodiment, The second power is greater than the first power. also, The second power exceeds at least the load of the power generating device 4. Here, Powertrain such as the workload per unit time, For a rotating body, it can be defined as a value proportional to the product of torque and rotation speed.  also, The first power system is generated based on unstable renewable energy, It varies according to the amount of renewable energy. therefore, There may be a case where the first power is temporarily larger than the second power. In this embodiment, The so-called "second power is greater than the first power", It is not to exclude such temporary situations where the first power exceeds the second power, The time average value intended for the first power is smaller than the second power.  The storage device 3 further includes: Control device 50, First sensor 51, And the second sensor 52. The first sensor 51 is disposed at a height close to a region where the weight 30 moves up and down. The second sensor 52 is disposed at a low position close to an area where the weight 30 moves up and down. The first sensor 51 detects a weight 30 at a first reference position (P1 described later). The second sensor 52 detects the weight 30 at a second reference position (P2 described later) which is located below the gravity direction than the first reference position.  In this embodiment, Gear 38A, 39A has a bidirectional clutch mechanism that can switch the driving direction and the idling direction (CL1 described later) CL2). This clutch mechanism uses, for example, electromagnetic control to switch the driving direction and the idling direction. It is controlled by the control device 50. The control device 50 is based on the detection signals of the first sensor 51 and the second sensor 52, Control gear 38A, 39A clutch mechanism.  FIG. 2 is a diagram schematically showing a first gear train 38 and a second gear train 39. First clutch mechanism CL1 provided by gear 38A The second clutch mechanism CL2 provided with the gear 39A constitutes a switching mechanism 53. The switching mechanism 53 switches the first state and the second state, The aforementioned first state allows rotation of the winder 35 in the winding direction and does not allow rotation of the winder 35 in the release direction, The aforementioned second state allows the winder 35 to rotate in the release direction.  The first clutch mechanism CL1 is a clutch mechanism that can switch the bidirectionality between the driving direction and the idling direction. that is, The gear 38A functions as a bidirectional clutch gear. The driving direction is the rotation direction of the gear 38A that transmits power between the first shaft 5 and the gear 38B. The idling direction is a rotation direction of the gear 38A that does not transmit power between the first shaft 5 and the gear 38B.  On the other hand, Although the second clutch mechanism CL2 has a driving direction and an idling direction, However, it is a unidirectional clutch mechanism that cannot switch between these directions. that is, The gear 39A functions as a one-way clutch gear. but, As the second clutch mechanism CL2, A two-way clutch mechanism can also be used.  The arrows shown by solid lines in Figure 2, It indicates the rotation direction of each gear when the bit can be stored. On the other hand, The arrow indicated by the dotted line indicates the rotation direction of each gear when the bit is available.  The first shaft 5 rotates in the same direction during storage and use. When stored in place, When the gear 38A receives the rotation of the first shaft 5 and rotates in the direction of a solid line arrow, The driving direction and the idling direction of the first clutch mechanism CL1 are set. Accept the rotation of the gear 38A, Gear 38B, 3rd axis 33, Gear 39B, The and gear 39A rotates in a direction indicated by a solid arrow. at this time, Idling with gear 39A, The second axis 7 does not rotate, The driving direction and the rotation direction of the second clutch mechanism CL2 are set. The winder 35 rotates in the winding direction together with the third shaft 33 and the wire body 37 is wound. The weight 30 rises.  When using bit energy, With the drop of weight 30, The winder 35 rotates in the release direction, The third shaft 33 rotates in a direction indicated by a dotted arrow. Accept the rotation of the third axis 33, Gear 38B and gear 39B rotate in the directions shown by the dotted arrows, As a result, the gear 39A and the gear 39A are also rotated in the directions indicated by the dotted arrows.  When available in place, With the control of the control device 50, The driving direction and the idling direction of the first clutch mechanism CL1 are reversed. therefore, Since gear 38A is idling, Therefore, the rotation of the gear 38A is not transmitted to the first shaft 5. On the other hand, Since the rotation of the gear 39A is consistent with the driving direction of the second clutch mechanism CL2, Therefore, upon receiving the rotation of the gear 39A, the second shaft 7 rotates. Accept the rotation of the second shaft 7 (second power), The power generating device 4 can generate power.  also, When stored in place, It is necessary to prevent the weight 30 from falling. In this embodiment, Using the load of the first shaft 5 (the load of the receiving device 2 and the transmission 6), The load with the second shaft 7 (the load of the power generating device 4) prevents the weight 30 from falling. that is, Even if the weight 30 is intended to be lowered when stored in place, At this time, the rotation direction of the gear 38A and the gear 39A is consistent with the driving direction. therefore, The loads of the first shaft 5 and the second shaft 7 act simultaneously, This prevents the weight 30 from falling.  also, Here is an example showing the use of the load of the first shaft 5 and the second shaft 7 to prevent the weight 30 from falling, But by setting up other institutions, To prevent the weight 30 from falling during energy storage.  Then, The operation of the storage device 3 will be described with reference to FIGS. 3 to 5.  When stored in place, The storage device 3 is set to the first state described above. at this time, With the first power transmitted through the first shaft 5, The first gear train 38 rotates the second shaft 33 in the winding direction. Accompanied by this, The winder 35 winds the wire body 37, The weight 30 rises as shown in FIG. 3. The position corresponding to the rising distance of the weight 30 can be stored in the storage device 3.  soon, As shown in FIG. 4, if the weight 30 reaches the first reference position P1, Then, the first sensor 51 detects the weight 30. at this time, The first sensor 51 outputs a detection signal to the control device 50. The control device 50 receives an input of a detection signal from the first sensor 51, Control switching mechanism 53 (mainly the first clutch mechanism CL1), The storage device 3 is switched to the second state described above.  also, In the first reference position P1, The weight 30 can also be located at a top dead center where it can no longer rise. E.g, It is possible to regulate the ascending member of the weight 30 by configuring, To determine the top dead center. At top dead center, Weight 30 stops, With this, the third shaft 33 and the gears also stop.  If you switch to the second state, As shown in Figure 5, The weight 30 is lowered by its own weight. that is, The winder 35 and the third shaft 33 rotate in the release direction. The rotation of the third shaft 33 in the releasing direction is transmitted to the second shaft 7 through the second gear train 39, The second shaft 7 rotates. Accept the rotation of the second axis 7, Which is the second power, The power generation device 4 generates electric power.  Since then, When the weight 30 reaches the second reference position P2, Then, the second sensor 52 detects the weight 30. at this time, The second sensor 52 outputs a detection signal to the control device 50. The control device 50 receives an input of a detection signal from the second sensor 52, Control switching mechanism 53 (mainly the first clutch mechanism CL1), The second state is switched to the first state. With this, The storage device 3 uses the first power reserve potential again.  also, In the second reference position P2, The weight 30 can also be located at a bottom dead point where it can no longer be lowered. E.g, It is possible to arrange the lowering member of the weight 30 by configuring, To determine the bottom dead center. or, The position of the weight 30 when the thread body 37 is fully released from the winder 35 may be the bottom dead center. At bottom dead center, Weight 30 stops, With this, the third shaft 33 and the gears also stop.  As mentioned above, The power generation system 1 of this embodiment repeatedly stores and uses potential energy.  The first power obtained from renewable energy is unstable, It is not always possible to obtain values suitable for power generation, There are situations where it sometimes stops. In previous generation systems, When the power from the receiving device is lower than the load of the power generating device, etc., There is no power generating device, And no access to electricity. In that case, The power generated by the receiving device is wasted.  In contrast, In the power generation system 1 of this embodiment, Even when the first power generated by the receiving device 2 is small, This first power can also be effectively used to generate electricity. that is, The first power from the receiving device 2 is temporarily stored as potential energy in the storage device 3. then, If the bits can be fully stored, Then the storage device 3 uses the bit energy to generate a second power exceeding the load of the power generating device 4. This second power is equivalent to the energy used when the weight 30 decreases by its own weight, It is extremely stable.  In addition, Various effects described above can also be obtained from this embodiment.  (Second Embodiment) A second embodiment will be described. Elements that are the same as or similar to those in the first embodiment are given the same symbols, The differences from the first embodiment will be mainly described.  FIG. 6 is a diagram showing a schematic configuration of the power generation system 1 according to the present embodiment. This power generation system 1 differs from that shown in FIG. 1 in the configuration of the storage device 3. that is, The storage device 3 includes n weights (n is an integer of 2 or more) 30, With n tackles 36. In the example of FIG. 6, n = 3, The storage device 3 includes a weight 30A, 30B, 30C and 36A, 36B, 36C. but, n can also be other values.  Furthermore, In the example of Figure 6, One end of the wire body 37 is connected to the winder 35, The other end is connected to the terminator 8. The thread body 37 is hung on a pulley 36A, 36B, 36C. 36A, 36B, The 36C and the terminator 8 have the same height in the direction of gravity, for example.  30A in weight, 30B, Above 30C, A rotatable roller 9 is installed. A wire body 37 is attached to each of the rollers 9, With this weight 30A, 30B, 30C is connected to the thread body 37.  In such a constitution, If the winder 35 is rotated in the winding direction by the first power, The wire body 37 is wound by the winder 35 and the weight 30A, 30B, 30C rises in the direction of gravity. With this, Corresponds to heavy object 30A, 30B, 30C weight and weight 30A, 30B, Bits with a 30C rise distance can be stored.  On the other hand, If the weight is 30A, 30B, 30C uses its own weight to descend in the direction of gravity. The winder 35 rotates in the release direction, The thread body 37 is released from the winder 35, The third shaft 33 rotates. The rotation of the third shaft 33 in the releasing direction is transmitted to the second shaft 7 through the second gear train 39, The second shaft 7 rotates. Accept the rotation of the second axis 7, Which is the second power, The power generation device 4 generates electric power.  also, Although not shown in Figure 6, However, the storage device 3 includes a first sensor 51, as in the first embodiment. Second sensor 52, 和 控制 装置 50。 And the control device 50. As long as the first sensor 51 and the second sensor 52 detect, for example, a heavy object 30A, 30B, Any one of 30C is sufficient.  In the configuration of this embodiment, The plurality of weights 30 can be distributed to store potential energy. therefore, Even if the rising distance of the weight 30 is reduced, It can also store sufficient potential energy.  Suppose, In the example of Figure 6, 30A in weight, 30B, When the weight of each of 30C is the same as the weight of the weight 30 shown in FIG. 1, The rising distance when the same potential energy is stored may be 1/3 of FIG. 1 in the example of FIG. 6.  other, Various suitable effects can be obtained from this embodiment.  Various modifications can be made to the configurations of the first and second embodiments described above. E.g, The configurations disclosed in the respective embodiments can be appropriately combined. Ways that change without departing from the gist of the invention, All are included in the inventions described in the scope of patent applications and their equivalents.  E.g, The storage device 3 may be provided with a member that guides the weight 30 to move up and down. If such a component is provided, Then, the weight 30 can be moved up and down stably.  It works, The storage device 3 includes a mechanism for transmitting the first power from the receiving device 2 to the power generating device 4 as it is, The mechanism can be switched between the mechanism and the storage mechanism. In this case, When renewable energy is sufficiently strong, such as when strong wind is blowing, The first power can be used to generate electricity.  The control method of the control device 50 for switching between the first state and the second state is not limited to the above. E.g, It works, After the first sensor 51 detects the weight 30 and switches to the second state, It switches to the first state when a certain period of time has elapsed. In that case, The second sensor 52 is not required. also, It works, After the second sensor 52 detects the weight 30 and switches to the first state, It switches to the second state when a certain period of time has elapsed. In that case, The first sensor 51 is not required. In addition, The first state and the second state may be switched at regular intervals. In this case, Both the first sensor 51 and the second sensor 52 are unnecessary. In addition, It works, Counting the number of rotations of the winder 35, etc. The first state and the second state are switched according to the count value. Various other control methods can be used.  (Third Embodiment) Fig. 7 is a diagram showing a schematic configuration of a power generation system 201 according to a third embodiment. The power generation system 201 includes: Renewable energy receiving device 202 (hereinafter referred to as receiving device 202), Storage device 203, And power generation device 204.  The receiving device 202 receives the renewable energy and generates a first power. Renewable energy can be used, for example, Wind, The force of the water moving up and down the surface is the wave force, The power of water flowing from a dam or the flow of water in a river is various energy sources such as hydraulic power generated by the flow of fluid. also, As a renewable energy, You can also use the power of the tide Or use water vapor generated by geothermal. Renewable energy is also referred to as renewable energy. The renewable energy receiving devices themselves, Those skilled in the art can know from, for example, Japanese Patent Laid-Open No. 2015-17614 and Japanese Patent Laid-Open No. 2015-17622. also, The renewable energy receiving device of the present invention is of course not limited to the devices described in Japanese Patent Application Laid-Open No. 2015-17614 and Japanese Patent Application Laid-Open No. 2015-17622.  The receiving device 202 and the storage device 203 are connected by a first shaft 205. In the example of Figure 7, The first power generated by the receiving device 2 is transmitted to the storage device 3 through the first shaft 205.  Details will be described later in the fourth to sixth embodiments, As the mechanism that receives the renewable energy and generates the first power, the receiving device 202 can adopt various mechanisms. For example, when the renewable energy is wind power, The receiving device 202 has: blade, It receives wind and rotates; And power generation mechanism, It rotates the first shaft 205 with the rotation of the blade. also, When renewable energy is wave power, The receiving device 202 has: Floating body, It moves up and down with the water surface; And power generation mechanism, The first shaft 205 rotates with the up and down movement of the floating body. In addition, Where renewable energy is hydro, The receiving device 202 has: Water turbine, It receives water and rotates; And power generation mechanism, It rotates the first shaft 205 with the rotation of the water turbine.  The constitution of the power generating mechanism is not particularly limited. E.g, In the case of wind or water, It may include a gear train transmitting a rotary motion of a blade or a turbine to the first shaft 205. also, In the case of wave force, Can include: rack, It reciprocates with the up and down movement of the floating body; And gear trains, It engages with the rack and rotates with the reciprocating motion of the rack to rotate the first shaft 205.  After the rotary motion of the blade or the turbine and the up and down motion of the floating body are converted into the reciprocating motion of the cable, It can be converted into a rotary motion of the first axis 205. As the above cable, E.g, The following constructions can be used, which is: Including a hollow external cable and an internal cable passing through the interior of the external cable, And the inner cable reciprocates inside the outer cable. By making the outer and inner cables flexible, Even if the mechanism that converts the reciprocating motion of the internal cable into a rotary motion is installed away from the blade, Water turbine, Or the position of the floating body, The two can also be easily connected.  In the example of Figure 7, A transmission 206 is interposed between the receiving device 202 and the storage device 203. Furthermore, The first axis 205 contains: Shaft 205A, It connects the receiving device 202 and the transmission 206; And shaft 205B, It connects the transmission 206 and the storage device 203. In this constitution, The shaft 205A is rotated by the first power of the receiving device 202. The speed changer 206 changes the speed of the shaft 205A (increasing or decreasing), The shaft 205B is rotated at the rotation speed after the speed change. The speed increase ratio or speed reduction ratio of the transmission 206 may be considered to accept the number of rotations and torque available from the device 2, Or, the number of rotations and torque required for the storage device 3 are appropriately set.  The storage device 203 and the power generation device 204 are connected by a second shaft 207. Details of the storage device 203 will be described later. Utilizing the first power reserve elastic energy transmitted through the first shaft 205, Use the stored elastic energy to generate a second power. The second power is transmitted to the power generation device 204 by a rotational motion of the second shaft 207.  The power generation device 204 converts the second power into electric power. Various specific configurations can be adopted as the specific configuration of the power generating device 204. As an example, The power generation device 204 shown in FIG. 7 includes: Speed governor 241, Power generation section 242, Power storage unit 243, And power transmission unit 244.  The second shaft 207 is connected to the speed governor 241 and the power generation section 242. The governor 241 adjusts the rotation speed of the second shaft 207 to a speed range suitable for power generation. As a governor 241, For example, a centrifugal governor can be used. The power generation unit 242 generates electric power based on the rotational movement of the second shaft 207. As a structure of such a power generation section 242, Various well-known structures can be adopted. The power storage unit 243 includes a battery that stores power generated by the power generation unit 242. The power transmission unit 244 supplies the power stored in the power storage unit 243 to the power transmission line at a specific voltage and current. The transmission line can be part of the existing transmission grid, Can also be in the workshop, Tall buildings, It is set up in a special building such as a residential building or the like for its purpose.  The storage device 203 includes an elastic body, By using the first power to elastically deform the elastic body, elastic energy corresponding to the elastic coefficient and deformation amount of the elastic body is stored. and then, When the elastic body is released from elastic deformation, The storage device 203 uses the elastic energy stored in the elastic body to generate a second power. So so The storage device 203 performs storage and utilization of elastic energy by elastic deformation and release of the elastic body. As long as it is such a function, The structure of the storage device 203 is not particularly limited.  In this embodiment, The second power is greater than the first power. also, The second power exceeds at least the load of the power generating device 204. Here, Powertrain such as the workload per unit time, For a rotating body, it can be defined as a value proportional to the product of torque and rotation speed.  also, The first power system is generated based on unstable renewable energy, It varies according to the amount of renewable energy. therefore, There may be a case where the first power is temporarily larger than the second power. In this embodiment, The so-called "second power is greater than the first power", It is not to exclude such temporary situations where the first power exceeds the second power, The time average value intended for the first power is smaller than the second power.  8 and 9 are diagrams showing a configuration example of the storage device 203. The storage device 203 in this example is shown in FIG. 8. have: Cam 230, 3rd axis 231, 1st gear train 232, And second gear train 233. Furthermore, As shown in FIG. 9, the storage device 203 includes: Elastomer 234, Track 235, Stopper 236, And slide 237.  The first gear train 232 transmits the rotational movement of the first shaft 205 (shaft 205B) to the third shaft 231. The second gear train 233 transmits the rotational movement of the third shaft 231 to the second shaft 207.  In the example of Figure 8, The first gear train 232 includes gears 232A, 232B (first gear). Gear 232A is mounted on the first shaft 205 (shaft 205B), It rotates around the shaft 205B. Gear 232B is mounted on the third shaft 231, The third axis 231 is rotated as an axis. Gear 232A has a smaller diameter than gear 232B. The gear 232A has, for example, a one-way clutch mechanism, When the shaft 205B is rotated in a certain direction by the first power, the rotation is transmitted to the gear 232B, It is idling when rotating in other directions.  On the other hand, The second gear train 233 includes gears 233A, 233B (second gear). Gear 233A is mounted on the second shaft 207, It rotates about the 2nd shaft 207 as an axis | shaft. Gear 233B is mounted on the third shaft 231, The third axis 231 is rotated as an axis. Gear 233A has a smaller diameter than gear 233B.  The cam 230 is mounted on the third shaft 231, The third axis 231 is rotated as an axis. E.g, The cam 230 is a circular plate cam whose distance between the circumferential surface of the curved surface and the third shaft 231 changes according to the rotation angle.  The elastic body 234 includes a ring body 238 made of, for example, a belt-shaped member. The ring body 238 can be elastically deformed in a radial direction. The ring body 238 may be formed of a metal material such as a steel material for spring, rubber, or the like. In the example of Figure 9, The elastic body 234 includes five ring bodies 238. but, The number of the ring bodies 238 contained in the elastomer 234 may be 4 or less. It may be 6 or more. The ring body 238 is perfectly circular in a natural state that is not elastically deformed, for example. but, The ring body 238 may have other shapes such as an oval shape or a polygonal shape in a natural state. also, The specific material of the ring body 238, Wall thickness, Width in the circumferential direction, And diameter, etc. Consider the required elasticity, Setting space, And manufacturing costs.  The elastic body 234 instead of the ring body 238 may also include, for example, a U-shaped member, V-shaped components, Or a ring-shaped member that combines two U-shaped members. These components are the same as the ring body 238, It can be formed of a metal material such as steel.  Each ring body 238 is mounted on the rail 235 via a slider 237. The slider 237 slides freely along the rail 235. The ring bodies 238 are aligned side by side along the rail 235. The outer peripheral surfaces of adjacent ring bodies 238 are in contact with each other. E.g, By arranging a roller or a ball at the contact portion between the rail 235 and the slider 237, And can reduce the loss caused by friction. Such a roller or a ball may be provided on any one of the rail 235 and the slider 237.  The outer peripheral surface of the cam 230 is in contact with the outer peripheral surface of the ring body 238 at the left end in FIG. 9. The outer peripheral surface of the ring body 238 at the right end in FIG. 9 is in contact with the stopper 236. Stopper 236, Track 235, The positional relationship with the third axis 231 is fixed, It does not change due to the rotation of the cam 230.  Then, The operation of the storage device 203 will be described with reference to FIGS. 9 to 12.  If the shaft 205B is rotated by the first power, Then gear 232A, 232B, 3rd axis 231, Cam 230, Gear 233A, 233B, The second shaft 207 rotates. at this time, Corresponding to the rotation angle of the cam 230, Each ring body 238 repeatedly undergoes elastic deformation (storage of elastic energy) and its release (utilization of elastic energy).  FIG. 10 shows a state when elastic energy is stored. While the distance between the position where the outer peripheral surface of the cam 230 contacts the ring body 238 and the third shaft 231 increases, The cam 230 presses each ring body 238 toward the stopper 236. With this, Each ring body 238 is elastically deformed in a direction indicated by an arrow in the figure to store elastic energy.  also, When elastic energy is stored, The force of the elastic body 234 pressing the cam 230 is smaller than the load of the shaft 205B (the load of the receiving device 202 and the transmission 206), The total with the load of the second shaft 207 (the load of the power generating device 204) is smaller. therefore, The cam 230 does not rotate in the reverse direction. or, It works, Another mechanism is provided in the storage device 203 so that the cam 230 does not rotate in the reverse direction when the elastic energy is stored.  soon, As shown in Figure 11, If the distance between the position where the outer peripheral surface of the cam 230 contacts the ring body 238 and the third shaft 231 reaches the maximum distance, Then the storage capacity of elastic energy becomes maximum.  FIG. 12 shows a state when elastic energy is used. While the distance between the position where the outer peripheral surface of the cam 230 contacts the ring body 238 and the third shaft 231 decreases, Since the elastic deformation of each ring body 238 is released, Therefore, the cam 230 is pressed in the direction indicated by the arrow in the figure. that is, The elastic energy stored in the elastic body 234 is utilized.  at this time, The cam 230 is rotated by the first power, It is also rotated by the force pressed by the elastic body 234. The power generated by the rotation of the cam 230 corresponds to the second power described above. This second power is transmitted to the power generating device 204 via the second shaft 207, The power generation device 204 generates power. Since then, If the distance between the position where the outer peripheral surface of the cam 230 contacts the ring body 238 and the third shaft 231 reaches the minimum distance, Then the elastic energy storage starts again.  also, When the elastic energy is stored, the second shaft 207 also rotates, However, due to the low rotation speed and torque, Therefore, the power generating device 204 does not generate power. Or even generating electricity, It also generates very little electricity. Generally speaking, The greater the power generated, the greater the load on the power generation device. therefore, The load of the power generation device 204 during elastic energy storage becomes extremely small.  From other perspectives, The speed ratio of the transmission 206 is determined in such a manner that the elastic body 234 is elastically deformed and the power generation device 204 does not generate electricity when the elastic energy is stored.  that is, Torque N1 to rotate shaft 205B, The torque N2 is smaller than the torque N2 required for power generation by the power generation device 204 (N1 <N2). or, The first power W1 transmitted through the shaft 205B is smaller than the third power W3 required for power generation by the power generation device 204. It is equal to or more than the fourth power W4 required for elastic energy storage using the storage device 203 (W4 ≦ W1 <W3). also, The second power W2 generated by the storage device 203 when the elastic energy is used is equal to or greater than the third power W3 (W3 ≦ W2).  As mentioned above, The power generation system 201 of this embodiment repeatedly stores and uses elastic energy. The first powertrain obtained from renewable energy is unstable, It is not always possible to obtain values suitable for power generation, There are situations where it sometimes stops. In previous generation systems, When the power from the receiving device is lower than the load of the power generating device, etc., There is no power generating device, And no access to electricity. In that case, The power generated by the receiving device is wasted.  In contrast, In the power generation system 201 of this embodiment, Even when the first power generated by the receiving device 202 is small, This first power can also be effectively used to generate electricity. that is, The first power from the receiving device 202 is temporarily stored as elastic energy in the storage device 203. then, If the elastic energy is adequately stored, Then, the storage device 203 uses the elastic energy to generate a second power exceeding the load of the power generating device 204. This second power is equivalent to the energy when the elastic body 234 releases elastic deformation, It is extremely stable.  In addition, Various effects described above can also be obtained from this embodiment.  (Fourth Embodiment) A fourth embodiment will be described. In this embodiment, A specific example of the receiving device 202 according to the third embodiment will be described. Elements that are the same as or similar to those in the third embodiment are given the same symbols, The differences from the third embodiment will be mainly described.  FIG. 13 is a diagram showing a configuration of a main part of a power generation system 201 according to the fourth embodiment. Here, This is an example of a configuration in which the receiving device 202 of the third embodiment receives a wave force and generates a first power. The receiving device 202 has: Floating body 220, Rack 221, And gear 222.  The floating body 220 floats on a water surface WF such as a sea or a lake. The floating body 220 moves up and down according to the position change of the water surface WF caused by the waves. The rack 221 is fixed to the floating body 220. The rack 221 includes a blade row 221 a that is aligned side by side in a direction that the floating body 220 moves up and down. The gear 222 is meshed with the blade row 221a. The gear 222 can rotate on the shaft 205A.  With the movement of the floating body 220 up and down, The rack 221 moves up and down. The gear 222 includes, for example, a one-way clutch mechanism, The rotation of the rack 221 when it is raised is transmitted to the shaft 205A, The rotation when the rack 221 is lowered is not transmitted to the shaft 205A. In this case, The rotational movement of the shaft 205A when the rack 221 is raised corresponds to the first power. opposite of this, The gear 222 can also transmit the rotation when the rack 221 is lowered to the shaft 205A. In this case, The rotation motion of the shaft 205A when the rack 221 is lowered corresponds to the first power. As another example, It works, By using multiple gears, The rotation of the rack 221 when it is raised and when it is lowered is transmitted to the shaft 205A. In this case, The rotational movement of the shaft 205A during the ascent and descent of the rack 221 corresponds to the first power.  also, In Figure 13, An example in which the floating body 220 and the rack 221 are fixed is shown. however, The floating body 220 and the rack 221 may also be connected by the internal cables and external cables described above. In this case, The degree of freedom of the installation positions of the floating body 220 and the storage device 203 is improved.  (Fifth Embodiment) A fifth embodiment will be described. In this embodiment, Another specific example of the receiving device 202 according to the third embodiment is disclosed. Elements that are the same as or similar to those in the third embodiment are given the same symbols, The differences from the third embodiment will be mainly described.  FIG. 14 is a diagram showing a configuration of a main part of a power generation system 201 according to a fifth embodiment. Here, The receiving device 202 according to the third embodiment is exemplified by a configuration in which the first power is generated by receiving wind power. The receiving device 202 includes a blade 223. Storage device 203, Power generation device 204, The transmission 206 is housed in a pod 301 supported at a high place by a pillar 300. Part of the power generating device 204, For example, the power storage unit 243 or the power transmission unit 244 may be provided outside the pod 301. In the example of Figure 14, Each ring body 238 and the stopper of the elastic body 234 are in the vertical direction (the direction of gravity, The extension directions of the pillars 300) are side by side.  The blade 223 can rotate around the shaft 205A. In this constitution, When the blade 223 rotates while receiving the wind, The shaft 205A rotates. The rotational movement of the shaft 205A corresponds to the first power.  also, In Figure 14, An example in which the rotational movement of the blade 223 is directly transmitted to the shaft 205A is shown. however, The above-mentioned internal cable and external cable may be interposed between the blade 223 and the shaft 205A. In this case, For example, a mechanism for converting the rotary motion of the blade 223 into a reciprocating motion of the internal cable and a mechanism for converting the reciprocating motion of the internal cable into a rotational motion of the shaft 205A are provided. If so, Then, the storage device 203 and the power generation device 204 may be disposed outside the pod 301.  (Sixth Embodiment) A sixth embodiment will be described. In this embodiment, Another specific example of the receiving device 202 according to the third embodiment is disclosed. Elements that are the same as or similar to those in the third embodiment are given the same symbols, The differences from the third embodiment will be mainly described.  FIG. 15 is a diagram showing a configuration of a main part of a power generation system 201 according to a sixth embodiment. Here, The receiving device 202 of the third embodiment is exemplified by a configuration in which the first power is generated by receiving the hydraulic power of water flowing in a river or the like. The receiving device 202 includes a water turbine 224 which is immersed in flowing water R flowing in a river or the like below. The water turbine 224 receives the force of flowing water R, It rotates around the shaft 205A. The rotational movement of the shaft 205A corresponds to the first power.  also, In Figure 15, An example in which the rotary motion of the water turbine 224 is directly transmitted to the shaft 205A is shown. however, The above-mentioned internal cables and external cables may be provided between the water turbine 224 and the shaft 205A. In this case, For example, a mechanism that converts the rotary motion of the water turbine 224 into the reciprocating motion of the internal cable and a mechanism that converts the reciprocating motion of the internal cable into the rotational motion of the shaft 205A are provided. If so, Then, the degree of freedom of the installation positions of the water turbine 224 and the storage device 203 is increased.  (Seventh Embodiment) A seventh embodiment will be described. In this embodiment, Another example of the storage device 203 is disclosed. Elements that are the same as or similar to those in the third embodiment are given the same symbols, The differences from the third embodiment will be mainly described.  FIG. 16 is a diagram showing a schematic configuration of a storage device 203 according to the seventh embodiment. The storage device 203 includes: Gear 330 (first gear), Gear 331 (second gear), Gear 332 (third gear), Rack 333, Movable member 334, Sensor 335, And control device 336. Furthermore, The storage device 203 includes the same as the third embodiment: Track 235, Stopper 236, Elastomer 234, And slide 237. In the example of Figure 16, The elastic body 234 includes three ring bodies 238. but, The number and shape of the ring bodies 238 are not particularly limited.  The gear 330 can rotate on the shaft 205B. The gear 331 can rotate on the second shaft 207 as an axis. The gear 332 can rotate on a shaft 337.  The rack 333 has a blade row 333a arranged linearly. The movable member 334 is connected to one end of the rack 333. Furthermore, The movable member 334 is in contact with the outer peripheral surface of the ring body 238 arranged at the left end in the figure.  Gear 332 and Gear 330, Gear 331, And the blade row 333a meshes. With the rotation of gear 332, The rack 333 and the movable member 334 reciprocate in a direction approaching the stopper 236 and a direction away from the stopper 236.  In this embodiment, The gear 330 has a first clutch mechanism CL1 that can switch the bidirectionality between the driving direction and the idling direction. The first clutch mechanism CL1 is one that switches the driving direction and the idling direction by, for example, electromagnetic control. It is controlled by the control device 336.  E.g, The sensor 335 detects that the rack 333 or the movable member 334 has reached the first reference position and the second reference position. The first reference position is, for example, a position where the mark M1 given to the rack 333 and the sensor 335 face each other. The second reference position is, for example, a position where the mark M2 given to the rack 333 and the sensor 335 face each other. The sensor 335 detects a mark M1, A detection signal is output at M2. E.g, The sensor 335 detects the marks M1 optically. Optical sensor of M2. The sensor 335 may also detect the marks M1 magnetically. M2 magnetic sensor and other types of sensors.  The control device 336 controls the first clutch mechanism CL1 based on a detection signal from the sensor 335. that is, The gear 330 functions as a bidirectional clutch gear. In the first clutch mechanism CL1, The driving direction is the rotation direction of the gear 330 that transmits power between the shaft 205B and the gear 332. The idling direction is the rotation direction of the gear 330 that does not transmit power between the shaft 205B and the gear 332.  also, In this embodiment, The gear 331 has a driving direction and an idling direction, However, the second clutch mechanism CL2 has a unidirectional property that cannot switch between these directions. that is, The gear 331 functions as a one-way clutch gear. but, As the second clutch mechanism CL2, A two-way clutch mechanism can also be used. In the second clutch mechanism CL2, The driving direction is the rotation direction of the gear 331 that transmits power between the second shaft 207 and the gear 332. The idling direction is a rotation direction of the gear 331 which does not transmit power between the second shaft 7 and the gear 332.  The first clutch mechanism CL1 and the second clutch mechanism CL2 constitute a switching mechanism 340. The switching mechanism 340 switches the first state that allows the elastic deformation of the elastic body 234, The second state of elastic deformation with the release elastic body 234.  The arrows shown by the solid lines in FIG. 16 indicate the rotation directions of the gears when the elastic energy is stored. on the other hand, The arrows indicated by the dotted lines show the rotation directions of the gears when the elastic energy is used.  The shaft 205B rotates in the same direction during the storage of elastic energy and during use. When elastic energy is stored, In a manner that the gear 330 receives the rotation of the shaft 205B and rotates in the direction of the solid arrow, The driving direction and the idling direction of the first clutch mechanism CL1 are set. Accept the rotation of the gear 330, Gear 332, Gear 331, The and gear 331 rotates in a direction indicated by a solid arrow. at this time, Idling with gear 331, The second axis 207 does not rotate, The driving direction and the rotation direction of the second clutch mechanism CL2 are set. With the rotation of gear 332, The rack 333 and the movable member 334 move toward the stopper 236. and then, Each ring body 238 is elastically deformed by being pressed by the movable member 334.  When using elastic energy, The movable member 334 and the rack 333 are pressed by the elastic body 234 in a direction away from the stopper 236, As a result, the gear 332 rotates in a direction indicated by a dotted arrow. Accept the rotation of the gear 332, The gear 330 and the gear 331 rotate in a direction indicated by a dotted arrow.  When using elastic energy, Utilizing the control of the control device 336, The driving direction and the idling direction of the first clutch mechanism CL1 are reversed. therefore, Since gear 330 is idling, Therefore, the rotation of the gear 330 is not transmitted to the shaft 205B. On the other hand, Since the rotation of the gear 331 coincides with the driving direction of the second clutch mechanism CL2, Therefore, upon receiving the rotation of the gear 331, the second shaft 207 rotates. Accept the rotation of the second shaft 207 (second power), The power generating device 204 can generate power.  also, When elastic energy is stored, It is necessary to prevent the elastic deformation of the elastic body 234 from being released. In this embodiment, The load of the shaft 205B (the load of the receiving device 202 and the transmission 206), The load on the second shaft 207 (the load on the power generating device 204) prevents the elastic body 234 from being released from the elastic deformation. that is, Even when the elastic body 234 intends to press the movable member 334 and the rack 333 away from the stopper 236 when the elastic energy is stored, At this time, any of the rotation directions of the gear 330 and the gear 331 coincides with the driving direction. therefore, The loads of the shaft 205B and the second shaft 207 act simultaneously, The movement of the movable member 334 and the rack 333 can be prevented.  also, Here is an example of preventing the elastic body 234 from being released by the load of the shaft 205B and the second shaft 207, But by setting up other institutions, To prevent the release of elastic deformation during energy storage.  Then, The operation of the storage device 203 will be described with reference to FIGS. 16 to 19.  When elastic energy is stored, The storage device 203 is set to the first state described above. at this time, As shown in Figure 17, Gear 330, 332 rotates with the first power transmitted through the shaft 205B, The rack 333 and the movable member 334 move toward the stopper 236. Accompanied by this, Each ring body 238 is elastically deformed, The elastic energy corresponding to the elastic deformation is stored in the storage device 203.  soon, As shown in FIG. 18, if the sensor 335 faces the mark M1, Then, the sensor 335 outputs a detection signal. The control device 336 receives an input of a detection signal from the sensor 335, Control switching mechanism 340 (mainly the first clutch mechanism CL1), The storage device 203 is switched to the second state described above.  If you switch to the second state, As shown in Figure 19, The movable member 334 and the rack 333 are pressed by the release of the elastic deformation of the elastic body 234, The movable member 334 and the rack 333 move in a direction away from the stopper 236. Accepting the rotation of gear 332 and gear 331 at this time, Further, the rotation of the gear 331 is transmitted to the second shaft 207, The second shaft 207 rotates. Accept the rotation of the second axis 207, Which is the second power, The power generation device 204 generates electric power.  Since then, As shown in Figure 16, If the sensor 335 is facing the mark M2, Then, the sensor 335 outputs a detection signal. The control device 336 receives an input of a detection signal from the sensor 335, Control switching mechanism 340 (mainly the first clutch mechanism CL1), The storage device 203 is switched to the first state described above. With this, The storage device 203 uses the first power reserve elastic energy again.  As mentioned above, The same is true in the power generation system 201 of this embodiment, Repeated storage and utilization of elastic energy. The configuration of the storage device 203 disclosed in this embodiment can be applied to any of the fourth to sixth embodiments.  Various changes can be made to the configurations of the third to seventh embodiments described above. E.g, The configurations disclosed in the respective embodiments can be appropriately combined. Ways that change without departing from the gist of the invention, All are included in the inventions described in the scope of patent applications and their equivalents.  E.g, In various embodiments, An example in which the storage device 203 stores elastic energy by compressing the elastic body 234 is disclosed. however, The storage device 203 can store elastic energy by extending the elastic body 234, It can also be continuously compressed and stretched for storage.  It works, The storage device 203 includes a mechanism for transmitting the first power from the receiving device 202 to the power generating device 204 as it is, The mechanism can be switched between the mechanism and the elastic energy storage mechanism. In this case, When renewable energy is sufficiently strong, such as when strong wind is blowing, The first power can be used to generate electricity.  In the seventh embodiment, The control method of the control device 336 for switching between the first state and the second state is not limited to the above. E.g, It works, After the sensor 335 detects the mark M1 and switches to the second state, It switches to the first state when a certain period of time has elapsed. In that case, No need to mark M2 for detection. also, It works, After the sensor 335 detects the mark M2 and switches to the first state, It switches to the second state when a certain period of time has elapsed. In that case, It is not necessary to mark the detection of M1. In addition, The first state and the second state may be switched at regular intervals. In that case, No sensor 335 is required. In addition, It works, Counting the number of rotations of gears 332, etc. The first state and the second state are switched according to the count value. Various other control methods can be used.  The method of elastically deforming the elastic body 234 in the storage device 203 is not limited to those using the cam 230 or the rack 333. E.g, You can also use the ball screw mechanism, It includes a screw that rotates with the rotation of the shaft 205B, And the nut screwed into the screw via a ball. that is, In this ball screw mechanism, If the elastic body 234 compresses or expands with the movement of the nut, The elastic body 34 can be elastically deformed.  [Industrial Applicability] According to the present invention, Among the many problems with previous generation systems using renewable energy, At least it can solve the problem of threshold value due to the operation of the energy receiving department, Problems with thresholds of power generation systems, The problem of power generation efficiency, The problem of the power storage performance of power storage devices such as batteries caused by the non-sustainable power generation.  According to the invention, Can be relatively simple to improve power generation efficiency, It is possible to realize a low-cost and high-efficiency power generation system. This fact undoubtedly makes a huge contribution to improving the performance of the system and contributing to wind power and wave power for civilian life.  and then, In addition to the combination of the potential energy storage device or the elastic energy storage device of the present invention with a renewable energy receiving device, It can also be combined with external power such as manpower or crane trucks, For remote areas, Used for emergency power generation devices. that is, In a remote area like a jungle, By replacing renewable energy, By combining manpower to store potential or elastic energy and generate electricity, In an emergency, The weight of the device can be lifted by using external forces such as a crane, While applying potential energy or elastic energy, This provides long-term stable power generation.  In other words, In the invention described in this specification, Together with the inventions described in the scope of the patent application, they include: "Power generation system with storage device and power generation device, The aforementioned storage device is the first power reserve energy or elastic energy using external power, And use the stored potential energy or elastic energy to generate a second power greater than the first power, The power generation device is a person that converts the second power to electricity ", And "Positive energy storage devices or elastic energy storage devices for power generation systems, It uses external power, which is the first power reserve energy or elastic energy.
