Abstract

A vertical water wheel, in which potential energy of water is converted into rotary motion. A generator must be operated at a certain revolution speed in order to produce electric power. Since a conventional vertical water wheel is constructed such that vanes are fixed to outer peripheral wheels of the water wheel and a diameter of the water wheel is preset, it has a constructional drawback that its revolution speed is affected by a water flow velocity. In contrast, the present invention provides a slide vane vertical water wheel comprising lengthy slide vanes (5) slidably mounted to outer peripheral wheels (2). Further, the slide vane vertical water wheel, of which vanes are slidable, is provided with a control mechanism and a speed governing mechanism, so that the water wheel itself senses a change of water flow velocity to regulate a slide amount of the slide vanes (5) in accordance with change values, whereby a diameter of the water wheel is modified and an intended revolution speed of the water wheel is constantly maintained. In this manner, the present invention provides, as power for generators, a slide vane vertical water wheel, which maintains its constant revolution speed independently of a change in water flow velocity.

スライド羽根立て形水車 技術分野 Technical field of sliding bladed water turbine
この発明は、 水の位置エネルギーを回転運動に変換する、 立て形水車 についてなされたものである。 背景技術  The present invention has been made for a vertical turbine that converts the potential energy of water into rotational motion. Background art
電気を発電するには、 発電機をある一定の回転数に維持して運転する のが絶対条件である。 ところが、 従来の立て形水車は、 回転数が水の流速に左右される欠点 があるので、 粉挽きなどの単なる動力としては問題ないが、 発電装置の 動力としては本来不向きであった。 しカゝし、 導水路や導水管で流速が管理された水によって回転させた水 車を、 自家用程度の小規模な発電装置の動力としている例もあるが、 現在では、 高圧の水や蒸気を利用して高出力が得られる高性能のタ一ビ ン型式水車が、 大規模な多くの発電施設で活躍している。  In order to generate electricity, it is absolutely necessary to operate the generator at a certain speed. However, the conventional vertical turbine has the disadvantage that the number of revolutions depends on the flow velocity of the water, so there is no problem with simple power such as milling, but it was originally unsuitable as power for the power generator. In some cases, water turbines that are rotated by water whose flow velocity is controlled by headraces and water pipes are used as power for small-scale power generators for private use. High-performance turbine-type turbines that can obtain high output by utilizing water are used in many large-scale power generation facilities.
このように、 高性能なタービン型式水車が主流の現代社会では、 立て 形水車の存在は忘れ去られようとしている。 これに対し、 本発明は、 地球を守る、 環境に優しい発電装置の動力と して、 立て形水車を現代に蘇えらせるのを目的とする。  Thus, in the modern society where high-performance turbine-type turbines are the mainstream, the existence of vertical turbines is being forgotten. On the other hand, the present invention aims to revive a vertical water turbine in modern times as a power source for an environmentally friendly power generator that protects the earth.
発明の開示 回転体の回転比は、 回転体の径で設定されるので、 水車の径を変えれ ば、 水車の回転比も変わる。 そこで、 本発明は、 従来は、 立て形水車の構成構造にしっかりと固定 されて取り付けられている水車の羽根部を、 立て形水車本体において、 スライド自在の羽根部とすることにより、 立て形水車自からが、 水車の 径を調整できる構造とするものである。 DISCLOSURE OF THE INVENTION Since the rotation ratio of the rotating body is set by the diameter of the rotating body, if the diameter of the turbine is changed, the rotation ratio of the turbine is also changed. In view of the above, the present invention provides a vertical water turbine, in which the blades of a water turbine fixed and attached to the structure of a vertical water turbine are slidable in the vertical water turbine main body. The structure is such that the diameter of the turbine can be adjusted by itself.
このように、 本発明は、 水の流速変化による立て形水車の回転比の変 動を、立て形水車自らが羽根部の伸縮により径を変えて調整し、もって、 立て形水車の回転比を一定値に維持できるようにしたものである。 Thus, according to the present invention, the change in the rotation ratio of the vertical turbine due to the change in the flow rate of water is adjusted by changing the diameter of the vertical turbine itself by the expansion and contraction of the blades, whereby the rotation ratio of the vertical turbine is adjusted. It is designed to be able to maintain a constant value.

これをもって、 歯車リンク方式からなる、 スライド羽根立て形水車の コントロール機構としたもので、 回転軸スライド案内円板 2 8の位置を 制御することで、 スライド羽根の径位置をコントロールする。  With this, the control mechanism of the slide blade standing type water turbine of the gear link type is used. By controlling the position of the rotary shaft slide guide disk 28, the diameter position of the slide blade is controlled.
なお、 図面は省略するが、 多軸油圧シリンダー 1 6でスライドされる スライド羽根立て形水車のコントロールは、 第 2 2図で示したコント口 ール機構から、 大径歯車 2 1を除去し、 リンクされたリンクロープ 2 9 の両端を、 直接、 多軸油圧シリンダー 1 6の入力レバーに直結するもの である。 さらに、 リンクロープ 2 9の位置変化点には、 随意、 適宜な案内口一 ラを配するものとする。 Although illustration is omitted, the control of the slide vane-type turbine driven by the multi-shaft hydraulic cylinder 16 removes the large-diameter gear 21 from the control mechanism shown in Fig. 22. Both ends of the linked link rope 29 are directly connected to the input lever of the multi-axis hydraulic cylinder 16. In addition, at the point where the position of the link rope 29 changes, an appropriate guideway is optionally arranged.
次ぎに、 本発明による、 コントロール機構を設けたスライド羽根立て 形水車に、 調速機構を設けるのを説明する。  Next, a description will be given of the provision of a speed control mechanism in a slide vane type water turbine provided with a control mechanism according to the present invention.
第 2 3図で示すように、 回転軸スライ ド案内円板 2 8を、 两側から挟 むローラ 3 4を設けた挟持アーム 3 5を、 回転軸スライド案内円板 2 8 の円板部を挟持させて位置し、 As shown in Fig. 23, the holding arm 35 provided with the roller 34 holding the rotary shaft slide guide disk 28 from the 两 side, and the disk portion of the rotary shaft slide guide disk 28 It is located to be pinched,
そして、 調速装置 3 0を、 回転軸 6に設けた、 調速装置駆動歯車 3 6 にリンクして装着し、  Then, the speed control device 30 is attached by linking to the speed control device drive gear 36 provided on the rotating shaft 6,
その調速装置 3 0に、 リンク出力を増幅させる油圧シリンダ一3 1を 、 調速装置の出力レバー 3 3と、 油圧シリンダ一入力レバ一 3 2でリン クして取り付け、 さらに、 油圧シリンダー 3 1と、 挟持アーム 3 5とを 連結する。  A hydraulic cylinder 31 that amplifies the link output is attached to the governor 30 by linking it with an output lever 33 of the governor and a hydraulic cylinder input lever 3 2. 1 and the holding arm 35 are connected.
これをもって、 スライド羽根立て形水車の調速機構としたもので、 調 速装置 3 0は、 水車の回転数で分銅部の上下値を決めるので、 その分銅 部の有効利用範囲の中間値の位置で、 意図する回転数が得られるように リンク設定しておけば、 設定した水車の回転数に変動が生じた場合、 分 銅部の変値に応じて、 即、 スライ ド羽根の径値が調整され、 結果、 水車 の回転数は、 常に当初の設定値に維持されるものである。  This is the speed control mechanism for the slide vane type water turbine, and the speed control device 30 determines the upper and lower values of the weight part based on the rotation speed of the water turbine. If the link speed is set so that the intended speed can be obtained, if the set speed of the turbine fluctuates, the diameter value of the slide blade immediately changes according to the variable value of the weight. As a result, the turbine speed is always maintained at the original setting.
なお、 調速機構に供される油圧シリンダー 3 1は、 調速機構及びコン トロール機構のリンク出力増幅のための捕助として設置されたものであ るから、 モータ等を利用した他のシステムによる増幅装置に代替されて も一向に構わない。 さらに、 調速装置 3 0も、 電子機器からなる流速センサーやリモート コントロール装置に代替されてもかまわないし、 又、 ハンドルなどを手 で回す、 手動方式で調速入力されても一向に構わない。 Since the hydraulic cylinder 31 used for the speed control mechanism is installed as an aid for amplifying the link output of the speed control mechanism and the control mechanism, it is necessary to use another system using a motor or the like. It does not matter if it is replaced with an amplification device. Further, the speed control device 30 may be replaced with a flow rate sensor or a remote control device formed of an electronic device, or the speed control may be input manually by turning a handle or the like.
産業上の利用可能性  Industrial applicability
従来の羽根が固定された立て形水車を、 発電装置の動力に利用する場 合は、 発電機の回転数を一定にするため、 発電装置に変速機を装着しな ければならない、 しかし、 高出力で回転中の水車と、 高負荷の回転力を 必要とする発電機の間で機能する変速機は、 変速のための水車の出力抑 制が許されない状態で変速するので、 技術的に非常に困難な要素が多々 存在するのと、 変速機を構成する素材の耐久性等の問題で頻繁な運転ト ラブルが懸念され、 結果、 従来の立て形水車は、 変速機を要しない小規 模な自家用程度の発電装置に利用されているにすぎなかった。 If a conventional vertical turbine with fixed blades is used to power the generator, a transmission must be fitted to the generator to keep the generator rotating at a constant speed. A transmission functioning between a turbine rotating at output and a generator that requires high-load rotational force shifts gears in a state where output control of the turbine for shifting is not allowed, so it is technically very difficult. There are many factors that are difficult to implement, and there are concerns about frequent driving problems due to problems such as the durability of the materials that make up the transmission.As a result, the conventional vertical turbine has a small size that does not require a transmission It was only used for power generators for private use.
これに対し、 本発明は、 上記したように、 立て形水車の羽根をスライ ド自在とし、 なおかつ、 コントロール機構と、 調速機構を設けた、 変速 機の機能を水車に持たせた、 スライド羽根立て形水車としたものである 力 ら、 水の流速がどのように変化しても、 調速機構とコントロール機構 のリンクよつて、他のいかなる構造部位にも無理な負担をかける事無く、 スムーズに、スライド羽根 5のスライド調整がなされて水車径を変更し、 結果、予め設定された水車の回転数は、常に一定値に維持されるので、 中規模の発電装置の動力として、なんの懸念も無く供されるものである。  On the other hand, as described above, according to the present invention, a slide blade in which the function of a transmission having a control mechanism and a speed control mechanism is provided to a water turbine is provided, as described above. No matter how the flow velocity of the water changes, the power is smooth, without imposing an unreasonable burden on any other structural parts by the link between the governing mechanism and the control mechanism. In addition, the slide blades 5 are adjusted to slide to change the diameter of the turbine, and as a result, the preset rotation speed of the turbine is always maintained at a constant value. It is provided without any.
このように、 本発明は、 従来の立て形水車を、 スライド羽根立て形水 車として、 中規模の発電装置の動力とするのを最大の狙いとしてなさ れたものである。 ところで、 延々と流れ下る世界各地の河川の水は、 水が流れているか ぎり、 その流域のどの地点においても位置エネルギーを有しているが、 現在、 その多くの河川の無限の位置エネルギーのほとんどは、 有効に活 用されることなく海に吸収され消滅している。 As described above, the present invention has been made with the greatest aim of using a conventional vertical turbine as a slide blade vertical turbine and powering a medium-scale power generator. By the way, as long as water flows, the water of rivers flowing endlessly around the world has potential energy at any point in its basin, but at present most of the infinite potential energy of many rivers Are absorbed and lost by the sea without being used effectively.
本発明は、 その、 これまで無作為に見過ごされていた膨大な水の位置 エネルギーを、 自ら回転数の調整が出来るスライド羽根立て形水車で、 電気エネルギーとして得るのを狙いとするもので、 世界各地の、 より多 くの河川の、 より多くの地点に、 その地点地点の地理に応じた、 大小の スライド羽根立て形水車からなる発電装置を設置して一斉に発電すれ ば、 一施設当たりの発電規模は小さくても、 計り知れない膨大な量の電 気が得られるものである。  The present invention aims to obtain, as electric energy, the huge potential energy of water, which was previously overlooked at random, by using a sliding bladed water turbine whose rotation speed can be adjusted by itself. If power generation equipment consisting of large and small slide bladed turbines according to the geography of the point is installed at more points in more rivers in various places, and power is generated simultaneously, Even though the power generation scale is small, an enormous amount of electricity that cannot be measured is obtained.
このように、 これまでただ無作為に放置してきた膨大な水の位置エネ ルギーを、 膨大な電気エネルギーとして得ることが出来るので、 これま で、 やむなく頼っている化石燃料による発電や、 原子力による発電を大 きく抑制することができるので、 現在、 地球的問題となっている環境破 壊防止と、 人類の将来的化石資源の節約に大いに貢献するとともに、 低 開発国の経済発展と生活向上にも大きく寄与するものである。  In this way, the huge amount of water energy that has been neglected until now can be obtained as a huge amount of electric energy, and power generation using fossil fuels and nuclear power generation that have been unavoidably relied on so far have been used. Greatly contribute to the prevention of environmental destruction, which is now a global problem, and to the saving of fossil resources in the future for humankind, as well as the economic development and livelihood improvement of underdeveloped countries. It will greatly contribute.
