Description

本発明は、水流や海流等の流体のエネルギーを利用して発電を行う発電装置に関するものである。   The present invention relates to a power generation apparatus that generates power using the energy of a fluid such as a water current or an ocean current.

近年、世界規模でのエネルギー需要の急速な増大に伴い、これまでもっぱら依存していた石油やＬＮＧ等の化石燃料や原子力等のエネルギー源の代替あるいは新たに加えるエネルギー源として、枯渇や公害の虞のない自然エネルギーを利用しようとする様々な研究開発が積極的に進められている。   In recent years, with the rapid increase in energy demand on a global scale, there is a risk of depletion and pollution as an alternative or newly added energy source such as fossil fuels such as oil and LNG, nuclear power, etc. Various research and development efforts are being made to use natural energy without energy.

このような自然エネルギーとしては、太陽光、潮流、風力等が利用可能であるが、いずれも時間や季節によって変動するという欠点を有している。これに対して、特に我が国においては、面積が小さい反面、周囲が海に囲まれているとともに、多くの河川を有しているために、時間や季節に関係なく、しかも無限であってエネルギー密度の高い海流や川の流れを利用した発電が可能となれば、有力なエネルギー源として活用することが可能になる。   As such natural energy, sunlight, tidal current, wind power, and the like can be used, but all have the disadvantage of fluctuating with time and season. On the other hand, especially in Japan, the area is small, but it is surrounded by the sea and has many rivers, so it has an infinite energy density regardless of time or season. If power generation using high currents and river flows becomes possible, it can be used as a powerful energy source.

この種の流体のエネルギーを利用した発電装置の内、例えば、海流を利用した発電装置としては、下記特許文献１において開示されたものが知られている。   Among power generation devices that use the energy of this type of fluid, for example, a power generation device that uses ocean currents is disclosed in Patent Document 1 below.

特開平７−２５９０６４号公報Japanese Patent Laid-Open No. 7-259064

It is.

上記課題を解決するため、請求項１に記載の本発明に係る発電装置は、一端部に流体の流入口が形成されるとともに他端部に排出口が形成された筒状の第１の導管と、この導管内に軸線を一致させて設けられ、縮径部が上記流入口側に配置され、かつ拡径部が上記排出口側に配置されることにより外周面と上記第１の導管の内周面との間に上記流入口から上記排出口に向けて漸次断面積が小さくなる流体の流路を形成する円錐状または切頭円錐状の内壁部と、上記流路内に上記軸線に対して傾斜して設けられることにより、当該流路内に導入された流体に円周方向の流れを形成させる複数枚の案内ブレードと、上記排出口に臨む位置に回転板が上記軸線廻りに回転自在に設けられるとともに、当該回転板の排出口と対向する面に、上記流体の流れを受けて回転させるための複数の翼が上記軸線を中心とする円周方向に間隔をおいて配置された回転部材と、この回転部材の回転により発電を行う発電手段とを備えてなることを特徴とするものである。   In order to solve the above problem, the power generator according to the present invention described in claim 1 is a cylindrical first conduit having a fluid inlet at one end and a discharge at the other end. And an axial line within the conduit, the reduced diameter portion is disposed on the inlet side, and the enlarged diameter portion is disposed on the outlet side, whereby the outer peripheral surface and the first conduit are A conical or frustoconical inner wall that forms a fluid flow path that gradually decreases in cross-sectional area from the inlet to the discharge opening between the inner peripheral surface and the axial line in the flow path By being provided with an inclination, a plurality of guide blades that form a flow in the circumferential direction in the fluid introduced into the flow path, and a rotating plate that rotates around the axis at a position facing the discharge port The surface of the rotating plate facing the discharge port of the rotating plate is provided freely. A plurality of wings for receiving and rotating the rotation member are provided with a rotating member arranged at intervals in a circumferential direction centering on the axis, and a power generation means for generating power by the rotation of the rotating member. It is characterized by.

また、請求項２に記載の発明は、請求項１に記載の発明において、上記回転部材が、上記内壁部の上記拡径部の直径と同径に形成されて当該内壁部と上記軸線方向に対向する第１の回転板と、この第１の回転板と間隔をおいて上記軸線方向の下流側に配置されるとともに上記第１の回転板よりも大径に形成された第２の回転板とを備え、上記第１および第２の回転板間に上記翼が配置され、かつ上記第２の回転板の外周に案内壁が立設されることにより、上記当該案内壁の先端と上記第１の回転板の外周縁との間に、上記排出口から排出された上記流体を上記翼へと導く開口部が形成されていることを特徴とするものである。   According to a second aspect of the present invention, in the first aspect of the present invention, the rotating member is formed to have the same diameter as the diameter of the enlarged-diameter portion of the inner wall portion, and the inner wall portion and the axial direction are formed. An opposing first rotating plate, and a second rotating plate that is disposed on the downstream side in the axial direction with a distance from the first rotating plate and that has a larger diameter than the first rotating plate The wings are arranged between the first and second rotating plates, and a guide wall is erected on the outer periphery of the second rotating plate, whereby the tip of the guide wall and the first An opening for guiding the fluid discharged from the discharge port to the wing is formed between the outer peripheral edge of one rotating plate.

さらに、請求項３に記載の発明は、請求項２に記載の発明において、上記第１の導管の外周に、互いの軸線を一致させ、かつ径方向に間隔をおいて第２の導管が設けられることにより、上記第１および第２の導管間に上記流体の外周流路が形成され、かつ当該外周流路内に、上記案内ブレードと同じ方向に傾斜する複数の外周案内ブレードが配置されるとともに、上記回転部材の第２の回転板は、上記開口が上記流路および外周流路の排出口に臨む外径寸法に形成されていることを特徴とするものである。   Furthermore, in the invention described in claim 3, in the invention described in claim 2, a second conduit is provided on the outer periphery of the first conduit so that the axes thereof coincide with each other and are spaced apart in the radial direction. Accordingly, an outer peripheral flow path of the fluid is formed between the first and second conduits, and a plurality of outer peripheral guide blades that are inclined in the same direction as the guide blade are disposed in the outer peripheral flow path. In addition, the second rotating plate of the rotating member is characterized in that the opening is formed to have an outer diameter that faces the outlet of the channel and the outer peripheral channel.

請求項１〜３のいずれかに記載の発明によれば、第１の導管の流入口を川の流れ方向や海流の上流側に位置させ、かつ軸線方向を上記流れに沿って配置することにより、上記流体が流入口から漸次断面積が小さくなる流路内を排出口側に向けて流れる過程において、ベルヌーイの定理から明らかなように、次第に流速を増すとともに、案内ブレードによって円周方向への旋回流を形成しつつ、最終的に上記排出口から回転部材側へと排出される。   According to the invention described in any one of claims 1 to 3, the inlet of the first conduit is located on the upstream side of the river flow direction or the ocean current, and the axial direction is arranged along the flow. In the process in which the fluid gradually flows from the inlet to the outlet through the flow path where the cross-sectional area gradually decreases, the flow velocity gradually increases and the guide blades move in the circumferential direction, as is apparent from Bernoulli's theorem. While forming a swirl flow, it is finally discharged from the discharge port to the rotating member side.

すると、この流体は、回転部材の回転板上に設けられた翼に衝突し、これにより回転板が軸線廻りに高速回転することにより、発電手段による発電が行われる。
このように、上記発電装置によれば、川の流れや海流等の流体の流れによる自然エネルギーを利用して効率的に発電することが可能になる。 Then, the fluid collides with a blade provided on the rotating plate of the rotating member, and the rotating plate rotates at high speed around the axis, thereby generating power by the power generating means.
As described above, according to the power generation device, it is possible to efficiently generate power using natural energy generated by a fluid flow such as a river flow or an ocean current.

この際に、請求項２に記載の発明によれば、上記排出口から排出された上記流体が、回転部材の開口から、第１および第２の回転板および円周方向に隣接する翼によって画成される空間内に案内されるために、上記流体のエネルギーをより一層効率的に回転部材の回転エネルギーに変換することができる。   In this case, according to the second aspect of the present invention, the fluid discharged from the discharge port is defined by the first and second rotating plates and the circumferentially adjacent blades from the opening of the rotating member. Since the fluid is guided into the formed space, the energy of the fluid can be more efficiently converted into the rotational energy of the rotating member.

さらに、請求項３に記載の発明によれば、第１の導管を第２の導管によって囲繞することにより、第１の導管内の流路の外周に、第１および第２の導管間の外周流路が形成されているために、第１の導管内の流路において流速が高められた流体の流れを、外周流路から排出される流体の流れによって案内することにより、外方の拡散させることなく回転部材へと導くことができ、一段と発電効率を向上させることができる。   According to the third aspect of the present invention, the first conduit is surrounded by the second conduit, so that the outer periphery of the flow path in the first conduit is connected to the outer periphery of the first and second conduits. Since the flow path is formed, the flow of the fluid whose flow velocity is increased in the flow path in the first conduit is guided by the flow of the fluid discharged from the outer peripheral flow path, and is diffused outward. Without being led to the rotating member, and the power generation efficiency can be further improved.

Thereby, the outer peripheral flow channel Fo is also divided into a plurality of (six in the figure) sections in the circumferential direction.

そして、第１の導管１の排出口１ｂ側の端部から軸線方向に延出する第２の導管４内には、回転部材６が上記軸線廻りに回転自在に設けられている。
この回転部材６は、間隔をおいて対向するとともに、第１および第２の導管１、４と軸線を一致させて回転自在に設けられた円板状の第１の回転板７および第２の回転板８と、これら第１および第２の回転板７、８間に設けられた複数枚（図では８枚）の翼９とから概略構成されたものである。 And in the 2nd conduit | pipe 4 extended in the axial direction from the edge part by the side of the discharge port 1b of the 1st conduit | pipe 1, the rotation member 6 is provided rotatably around the said axis line.

The rotary plate 8 and a plurality of (eight in the figure) blades 9 provided between the first and second rotary plates 7 and 8 are schematically configured.

この第１の回転板７は、内壁部２における拡径部２ｂの端面と略同径に形成されており、当該端面と僅かの間隔をおいて対向するように配置されている。他方、第２の回転板８は、第２の導管４の内壁よりも幾分小さな外形寸法に形成されており、当該第２の導管４の端部に配置されている。これにより、第２の導管４の内周面と第２の回転板８の外周面との間には、幅狭円環状の海水の排水流路ｆが形成されている。   The first rotating plate 7 is formed to have substantially the same diameter as the end surface of the enlarged diameter portion 2b in the inner wall portion 2, and is arranged to face the end surface with a slight gap. On the other hand, the second rotating plate 8 is formed to have a slightly smaller outer dimension than the inner wall of the second conduit 4, and is disposed at the end of the second conduit 4. Thus, a narrow annular seawater drainage flow path f is formed between the inner peripheral surface of the second conduit 4 and the outer peripheral surface of the second rotating plate 8.

さらに、翼９は、その板面が第１および第２の回転板７、８の半径方向に沿うように設けられている。そして、翼９間に位置する第２の回転板８の外周には、円周方向に向けて案内壁１０が立設されている。これにより、案内壁１０の先端と第１の回転板７の外周縁との間には、排出口１ａ、４ａから排出された海水の流れを翼９間へと導く開口部１１が形成されている。また、回転部材６の第２の回転板８の中心軸（図示を略す。）が、図示されない発電機に連結されている。   Further, the blade 9 is provided such that its plate surface is along the radial direction of the first and second rotating plates 7 and 8.

これにより、流速を増して排出口１ｂから排出された海水は、外周流路ｆから排出される海水の流れによって案内されることにより、外方へ拡散することなく、回転部材６の開口部１１内へと導かれる。そして、回転部材６の第１および第２の回転板７、８間に設けられた翼９に衝突し、これにより第１および第２の回転板７、８が軸線廻りに高速回転することにより、発電手段による発電が行われる。   As a result, the seawater discharged from the discharge port 1b at an increased flow velocity is guided by the flow of seawater discharged from the outer peripheral flow path f, so that the opening 11 of the rotating member 6 does not diffuse outward. Led in. And it collides with the wing | blade 9 provided between the 1st and 2nd rotary plates 7 and 8 of the rotation member 6, and, thereby, the 1st and 2nd rotary plates 7 and 8 rotate at high speed around an axis line.
