Description

流体駆動装置、及び発電装置Fluid drive device and power generation device
　本発明は、流体駆動装置、及び発電装置に関する。詳しくは、水力等の自然エネルギーを効率的に電気エネルギーに変換して発電効率を高めることができる流体駆動装置、及び発電装置に係るものである。 The present invention relates to a fluid drive device and a power generation device. More specifically, the present invention relates to a fluid drive device capable of efficiently converting natural energy such as hydraulic power into electric energy to increase power generation efficiency, and a power generation device.
　近年、化石燃料の枯渇に加えて地球温暖化等の地球環境問題が深刻化していることから、自然エネルギーを利用した発電装置、及び発電方法が注目されている。特に、ＣＯ２の排出権問題やＲＰＳ（Ｒｅｎｅｗａｂｌｅ　Ｐｏｒｔｆｏｌｉｏ　Ｓｔａｎｄａｒｄ）制度の導入により、今後さらにその重要性が増すことが予想される。 In recent years, in addition to the depletion of fossil fuels, global environmental problems such as global warming have become more serious, and accordingly, power generation apparatuses and power generation methods using natural energy have been attracting attention. In particular, the introduction of the emission rights issues CO 2 and RPS (Renewable Portfolio Standard) system, is expected to increase even more its importance in the future.
　例えば、自然エネルギー源である太陽光を利用する太陽光発電装置は、その設置が容易であるとともに発電コストも比較的安いことから、住宅や農業ハウスの屋根発電からメガソーラー発電所のような大規模設備までその普及が急速に進んでいる。 For example, photovoltaic power generators that use sunlight, a natural energy source, are easy to install and have relatively low power generation costs. It is rapidly spreading to large-scale facilities.
　また、従来の固定式の太陽光発電装置に加えて、設置工事等が不要であり、運搬や設置場所の変更を容易に行える携帯型の太陽光発電装置も注目されている。例えば特許文献１には、電源のない野外等の任意の場所に設置して利用することができる携帯型の太陽光発電装置が開示されている。 携 帯 In addition to the conventional fixed-type photovoltaic power generation devices, portable photovoltaic power generation devices that do not require installation work and can be easily transported and changed the installation location are also attracting attention. For example, Patent Literature 1 discloses a portable photovoltaic power generator that can be installed and used in an arbitrary place such as an outdoor without a power supply.
　具体的には、電気的に接続した多数のシート状、又はフィルム上の太陽光発電シートを収納ケース内に引き伸ばし自在に収納した状態で持ち運び可能とし、使用者は任意の場所にて収納ケースから太陽光発電シートを引き出すことで、電源のない野外においても太陽光を効率的に利用して発電することで電気機器を利用することが可能となっている。 Specifically, a large number of electrically connected sheets or a photovoltaic sheet on a film can be carried in a state where the sheets can be stretched and stored in the storage case, and the user can remove the storage case at any place. By pulling out the photovoltaic power generation sheet, it is possible to use electric equipment even in the outdoors where there is no power supply, by efficiently using the sunlight to generate power.
　また、風力や水力といった流体を作業体として駆動装置を駆動させることで発電機を発電させる流体駆動装置も数多く提案されている。例えば特許文献２には、河川や農業用水路等の水路に設置して、自然エネルギー源としての水を利用する水力発電装置が開示されている。 流体 Furthermore, a number of fluid drive devices for generating electric power by driving a drive device using a fluid such as wind power or hydraulic power as a work body have been proposed. For example, Patent Literature 2 discloses a hydroelectric power generation device that is installed in a waterway such as a river or an agricultural waterway and uses water as a natural energy source.
　具体的には、対向配置された２枚の円盤部と、円盤部の中心軸部から放射状に等間隔で取り付けられたパドル部からなる本体部を備え、水中のパドル部が水流圧を受けることにより、パドル部が接続される水軸が得られる回転力を利用して発電装置を駆動する構成となっている。 More specifically, the main body is composed of two disk portions disposed opposite to each other and a paddle portion radially attached from the center axis portion of the disk portion at equal intervals, and the paddle portion in water is subjected to water pressure. Thus, the power generator is driven by using the rotational force obtained by the water shaft to which the paddle portion is connected.

　しかしながら、前記した特許文献１に開示の太陽光発電装置においては、発電量が天候や日射量に左右されてしまい、特に晴れた日の昼間の日射量が比較的大きな時間帯でしか安定的な発電ができないという課題がある。 However, in the solar power generation device disclosed in Patent Document 1 described above, the amount of power generation depends on the weather and the amount of solar radiation, and is stable only in a relatively large time period during a sunny daytime when the amount of solar radiation is relatively large. There is a problem that power cannot be generated.
　一方、前記した特許文献２に開示の水力発電装置が設置される河川や農業用水路等では、季節ごとに所定の流量が維持されるように水量調整がされるため、継続的に一定の流量を確保することが可能である。そのため、太陽光発電装置のように日射量等の外部要因により発電量が不安定となることがなく、一年を通して安定的な発電が可能である。 On the other hand, in a river or an agricultural waterway in which the hydroelectric power generation device disclosed in Patent Document 2 is installed, the water flow is adjusted so that a predetermined flow is maintained every season. It is possible to secure. Therefore, the amount of power generation does not become unstable due to external factors such as the amount of solar radiation unlike the solar power generation device, and stable power generation can be performed throughout the year.
　しかしながら、特許文献２に開示の水力発電装置は、その直径が最大で約１．４ｍ程度と大型であり、例えば水深の浅い河川や、流速の遅い河川に設置した場合に、パドル部が水車を回転させるだけの十分な水圧を受けることができず、目論見通りの発電量が得られないことが懸念される。 However, the hydroelectric generator disclosed in Patent Document 2 has a large diameter of about 1.4 m at the maximum, and for example, when installed in a river with a shallow water depth or a river with a low flow velocity, the paddle section turns the water turbine. There is a concern that it is not possible to receive sufficient water pressure to rotate it, and it is not possible to obtain the expected power generation.
　本発明は、以上の点に鑑みて創案されたものであり、水力等の自然エネルギーを効率的に電気エネルギーに変換して発電効率を高めることができる流体駆動装置、及び発電装置を提供することを目的とする。 The present invention has been made in view of the above points, and provides a fluid drive device and a power generation device capable of efficiently converting natural energy such as hydraulic power into electric energy to increase power generation efficiency. With the goal.
　前記の目的を達成するために、本発明の流体駆動装置は、水平軸線に対して略平行な第１の回転軸を軸心部に含む第１の回転体、前記第１の回転軸と略平行な回転軸である第２の回転軸を軸心部に含み前記第１の回転体と所定の間隔で離間して設置される第２の回転体、前記第１の回転体から前記第２の回転体に向かう往路側から前記第２の回転体から前記第１の回転体に向かう復路側に向けて周回可能なように前記第１の回転体と前記第２の回転体に架設された無端状のベルト体、作動流体の流体圧を受圧する受圧面を含み前記ベルト体の回転方向に沿って所定の間隔で設けられた抵抗部材、を有する本体部と、前記ベルト体の往路側に位置する前記抵抗部材が露出可能な開口部が形成され、前記本体部の一部を被覆する断面略Ｕ字状のカバー部とを備える。 In order to achieve the above object, a fluid driving device according to the present invention includes a first rotating body including a first rotating shaft substantially parallel to a horizontal axis in an axial center portion, and a first rotating body substantially parallel to the first rotating shaft. A second rotating body that includes a second rotating shaft that is a parallel rotating shaft in an axis portion and is installed at a predetermined distance from the first rotating body; The first rotator and the second rotator are provided so as to be able to orbit from the second rotator to the return path toward the first rotator from the outward path toward the rotator. An endless belt body, a main body portion including a pressure receiving surface for receiving a fluid pressure of a working fluid, and a resistance member provided at predetermined intervals along a rotation direction of the belt body, and a forward side of the belt body. An opening for exposing the resisting member located is formed, and has a substantially U-shaped cross section covering a part of the main body. And a bar portion.
　ここで、流体駆動装置の本体部が、水平軸線に対して略平行な第１の回転軸を軸心部に含む第１の回転体を有することにより、後述するベルト体の回転運動に伴って、第１の回転体を回転させることができる。 Here, the main body of the fluid drive device has the first rotating body including the first rotating shaft substantially parallel to the horizontal axis in the axial center portion, so that the first rotating body is accompanied by the rotating motion of the belt body described later. , The first rotating body can be rotated.
　また本体部が、第１の回転軸と略平行な回転軸である第２の回転軸を軸心部に含み第１の回転体と所定の間隔で離間して設置される第２の回転体を有することにより、ベルト体の回転運動に伴って回転する第１の回転体に従動するように、第２の回転体を回転させることができる。 A second rotating body whose main body includes a second rotating shaft that is a rotating shaft substantially parallel to the first rotating shaft in the shaft center portion and is installed at a predetermined distance from the first rotating body. , The second rotating body can be rotated so as to be driven by the first rotating body that rotates with the rotational movement of the belt body.
　また本体部が、第１の回転体から第２の回転体に向かう往路側から第２の回転体から第１の回転体に向かう復路側に向けて周回可能なように第１の回転体と第２の回転体に架設された無端状のベルト体を有することにより、ベルト体からの駆動力を、第１の回転体、及び第２の回転体に伝達することができる。 In addition, the first rotating body and the first rotating body are configured so that the main body can rotate from a forward path from the first rotating body to the second rotating body toward a backward path from the second rotating body to the first rotating body. By having the endless belt member provided on the second rotating member, the driving force from the belt member can be transmitted to the first rotating member and the second rotating member.
　また本体部が、作動流体の流体圧を受圧する受圧面を含みベルト体の回転方向に沿って所定の間隔で設けられた抵抗部材を有することにより、作動流体からの作動圧を抵抗部材の受圧面で効率的に受圧させることができる。このとき、ベルト体を作動流体の流れ方向に沿って駆動させることができるため、前記した通り、作動流体の上流側に位置する第１の回転体から駆動を開始し、それに伴い作動流体の下流側に位置する第２の回転体が従動回転する。これにより、例えば第１の回転体の第１の回転軸、又は第２の回転体の第２の回転軸の何れか一方に発電機を接続することにより、第１の回転体の回転力、又は第２の回転体の回転力を発電機に伝達することで、発電機を効率的に発電させることができる。 Further, the main body portion includes a pressure receiving surface for receiving the fluid pressure of the working fluid, and has a resistance member provided at predetermined intervals along the rotation direction of the belt body, so that the working pressure from the working fluid is received by the resistance member. Pressure can be efficiently received. At this time, since the belt body can be driven along the flow direction of the working fluid, as described above, the driving starts from the first rotating body located on the upstream side of the working fluid, and accordingly, the downstream of the working fluid is started. The second rotating body located on the side rotates following. Thereby, for example, by connecting the generator to one of the first rotating shaft of the first rotating body or the second rotating shaft of the second rotating body, the rotational force of the first rotating body, Alternatively, by transmitting the torque of the second rotating body to the generator, the generator can be efficiently generated.
　また流体駆動装置が、ベルト体の往路側に位置する抵抗部材が露出可能な開口部が形成され、本体部の一部を被覆する断面略Ｕ字状のカバー部を備える場合には、本体部の大半の範囲がカバー部により被覆されるため、流体駆動装置を作動流体中に設置した場合でも、作動流体中に浮遊するゴミ等の異物から本体部を保護することができる。また、ベルト体の往路側に位置する抵抗部材にのみ作動流体が作用するため、ベルト体を効率的に回転させることができる。 In the case where the fluid driving device is provided with an opening capable of exposing the resistance member located on the outward path side of the belt body and includes a cover having a substantially U-shaped cross section that covers a part of the main body, Of the main body can be protected from foreign matter such as dust floating in the working fluid even when the fluid driving device is installed in the working fluid. Further, since the working fluid acts only on the resistance member located on the outward path side of the belt, the belt can be efficiently rotated.
　また、抵抗部材は、常態において起立位置となるように付勢されるバネ部材を含む基端軸を介してベルト体に設置されている場合には、作動流体中に設置された抵抗部材は常態においてベルト体に対して起立位置となるため、作動流体の流体圧を十分に受けることができ、ベルト体を効率的に回転させることができる。 Further, when the resistance member is installed on the belt body via a base shaft including a spring member which is urged to be in a standing position in a normal state, the resistance member installed in the working fluid is in a normal state. In this case, the belt body is in the standing position with respect to the belt body, so that the fluid pressure of the working fluid can be sufficiently received, and the belt body can be efficiently rotated.
　また、抵抗部材は、ベルト体に対して略垂直な起立位置と略平行な倒伏位置のそれぞれに起伏可能であることにより、例えば、作動流体の流れ方向と一致するベルト体の往路側においては起立位置とすることで、作動流体による流体圧を受圧面で十分に受圧できる。一方で、作動流体の流れ方向とは逆向きであるベルト体の復路側においては倒伏位置とすることで、ベルト体の回転を妨げる方向の作動流体の流体圧を受圧しないようにすることができる。これにより、作動流体の流れ方向に沿ってベルト体を効率的に回転させることができる。 In addition, the resistance member can be raised and lowered at a standing position substantially perpendicular to the belt body and a falling position substantially parallel to the belt body, so that, for example, the resistance member stands on the outward path side of the belt body that coincides with the flow direction of the working fluid. By setting the position, the fluid pressure by the working fluid can be sufficiently received on the pressure receiving surface. On the other hand, it is possible to avoid receiving the fluid pressure of the working fluid in the direction that hinders the rotation of the belt body by setting the falling position on the return path side of the belt body opposite to the flow direction of the working fluid. . Thereby, the belt body can be efficiently rotated along the flow direction of the working fluid.
　また、抵抗部材は、ベルト体の復路側に位置する抵抗部材の先端が、カバー部の底面と接触しながら第２の回転体の方向に向けて倒伏する場合には、ベルト体の復路側に位置する抵抗部材を起立位置から倒伏位置とすることができるため、作動流体による回転抵抗を弱め、ベルト体を効率的に回転させることができる。 In addition, the resistance member is located on the return path side of the belt body when the tip of the resistance member located on the return path side of the belt body falls down toward the second rotating body while contacting the bottom surface of the cover portion. Since the located resistance member can be shifted from the standing position to the falling position, the rotation resistance due to the working fluid is reduced, and the belt body can be rotated efficiently.
　また、第１の回転軸と第２の回転軸を結ぶ仮想直線は水平軸線に対して鉛直上方に向けて所定の角度を有する場合には、流体の流れ方向に対してベルト体の往路側に位置する抵抗部材が一定の迎角を有し、抵抗部材に作用する流体圧を大きくすることができるため、ベルト体を効率的に回転させることができる。 Further, when the virtual straight line connecting the first rotation axis and the second rotation axis has a predetermined angle vertically upward with respect to the horizontal axis, it is located on the outward path side of the belt body with respect to the flow direction of the fluid. Since the located resistance member has a fixed angle of attack and can increase the fluid pressure acting on the resistance member, the belt body can be rotated efficiently.
　また、カバー部は船型に形成されている場合には、カバー部に作用する作動流体による抵抗力を弱め、作動流体によるカバー部の破損等を防止することができる。 When the cover is formed in a hull form, the resistance of the cover to the working fluid acting on the cover can be reduced to prevent the cover from being damaged by the working fluid.
　また、第１の回転軸、及び第２の回転軸にはカバー部の側面を貫通するシャフト部を有し、シャフト部の両端には鉛直下方に延出する支柱を含む基台を有する場合には、本体部とカバー部が一体化されるとともに、基台部により流体駆動装置を安定した状態で設置面に設置することができる。 Further, in the case where the first rotating shaft and the second rotating shaft have a shaft portion penetrating the side surface of the cover portion, and both ends of the shaft portion have a base including a column extending vertically downward. The body and the cover are integrated, and the fluid drive device can be installed on the installation surface in a stable state by the base.
　また、ベルト体の往路側は、復路側に対して鉛直上方に位置し、カバー部は、鉛直上方に向けて開口部が形成されている場合には、例えば流体駆動装置を水位の低い水路等に設置する場合においても、カバー部の一部、又は全体を設置面に埋設することで、往路側に位置する抵抗部材を浸水させることができる。従って、往路側に位置する抵抗部材が作動流体の流体圧を受圧することで流体駆動装置を駆動することができる。 In addition, when the forward path side of the belt body is located vertically above the backward path side, and the cover portion is formed with an opening facing vertically upward, for example, the fluid drive device may be connected to a low water level channel or the like. Also, in the case where the resistance member is installed on the outbound path side, it is possible to immerse a part or the whole of the cover portion on the installation surface. Therefore, the fluid driving device can be driven by the resistance member located on the outward path receiving the fluid pressure of the working fluid.
　また、ベルト体の往路側は、復路側に対して鉛直下方に位置し、カバー部は、鉛直下方に向けて開口部が形成されている場合には、抵抗部材が鉛直下方に向けて外部に露出するため、例えば水位の低い水路等であっても抵抗部材を容易に浸水させることができる。従って、往路側に位置する抵抗部材が作動流体の流体圧を受圧することで流体駆動装置を駆動することができる。 In addition, the forward path side of the belt body is located vertically below the return path side, and when the cover has an opening formed vertically downward, the resistance member is outwardly directed vertically downward. Because of the exposure, the resistance member can be easily flooded, for example, even in a water channel having a low water level. Therefore, the fluid driving device can be driven by the resistance member located on the outward path receiving the fluid pressure of the working fluid.
　前記の目的を達成するために、本発明の発電装置は、水平軸線に対して略平行な第１の回転軸を軸心部に含む第１の回転体、前記第１の回転軸と略平行な回転軸である第２の回転軸を軸心部に含み前記第１の回転体と所定の間隔で離間して設置される第２の回転体、前記第１の回転体から前記第２の回転体に向かう往路側から前記第２の回転体から前記第１の回転体に向かう復路側に向けて周回可能なように前記第１の回転体と前記第２の回転体に架設された無端状のベルト体、該ベルト体の回転方向に沿って所定の間隔で設けられるとともに作動流体の流体圧を受ける略板状体からなる抵抗部材、を有する本体部と、前記第１の回転軸、前記第２の回転軸の何れか一方にシャフト部を介して接続された発電機と、前記ベルト体の往路側に位置する前記抵抗部材が露出可能な開口部が形成され、前記本体部の一部を収納可能な断面略Ｕ字状のカバー部とを備える。 In order to achieve the above object, a power generator according to the present invention includes a first rotating body including a first rotating shaft substantially parallel to a horizontal axis in an axial portion thereof, substantially parallel to the first rotating shaft. A second rotating body including a second rotating shaft, which is a simple rotating shaft, in an axial center portion and being spaced apart from the first rotating body at a predetermined interval, the second rotating body being separated from the first rotating body by the second rotating body; An endless bridge between the first rotating body and the second rotating body so that the first rotating body and the second rotating body can circulate from a forward path toward the rotating body toward a backward path toward the first rotating body from the second rotating body. A main body portion having a belt-shaped body, a resistance member formed of a substantially plate-shaped body provided at predetermined intervals along the rotation direction of the belt body and receiving the fluid pressure of the working fluid; and the first rotation shaft; A generator connected to one of the second rotation shafts via a shaft portion, and a generator connected to a forward path side of the belt body. The resistive member location is formed an opening which can be exposed, and a main body portion substantially U-shaped cross section of the cover portion capable of housing a part of.
　ここで、流体駆動装置の本体部が、水平軸線に対して略平行な第１の回転軸を軸心部に含む第１の回転体を有することにより、後述するベルト体の回転運動に伴って、第１の回転体を回転させることができる。 Here, the main body of the fluid drive device has the first rotating body including the first rotating shaft substantially parallel to the horizontal axis in the axial center portion, so that the first rotating body is accompanied by the rotating motion of the belt body described later. , The first rotating body can be rotated.
　また本体部が、第１の回転軸と略平行な回転軸である第２の回転軸を軸心部に含み第１の回転体と所定の間隔で離間して設置される第２の回転体を有することにより、ベルト体の回転運動に伴って回転する第１の回転体に従動するように、第２の回転体を回転させることができる。 A second rotating body whose main body includes a second rotating shaft that is a rotating shaft substantially parallel to the first rotating shaft in the shaft center portion and is installed at a predetermined distance from the first rotating body. , The second rotating body can be rotated so as to be driven by the first rotating body that rotates with the rotational movement of the belt body.
　また本体部が、第１の回転体から第２の回転体に向かう往路側から第２の回転体から第１の回転体に向かう復路側に向けて周回可能なように第１の回転体と第２の回転体に架設された無端状のベルト体を有することにより、第１の回転体の駆動力を、ベルト体を介して第２の回転体に伝達することができる。そのため、第１の回転体の駆動にともない、第２の回転体を従動させることができる。 In addition, the first rotating body and the first rotating body are configured so that the main body can rotate from a forward path from the first rotating body to the second rotating body toward a backward path from the second rotating body to the first rotating body. By having the endless belt mounted on the second rotator, the driving force of the first rotator can be transmitted to the second rotator via the belt. Therefore, the second rotating body can be driven by the driving of the first rotating body.
　また本体部が、ベルト体の回転方向に沿って所定の間隔で設けられるとともに作動流体の流体圧を受ける略板状体からなる抵抗部材を有することにより、作動流体からの作動圧を効率的に受圧させることができる。このとき、ベルト体を作動流体の流れ方向に沿って駆動させることができるため、前記した通り、作動流体の上流側に位置する第１の回転体から駆動を開始し、それに伴い作動流体の下流側に位置する第２の回転体が従動される。これにより、例えば第１の回転体の第１の回転軸、又は第２の回転体の第２の回転軸の何れか一方に発電機を接続することにより、効率的に発電させることができる。 In addition, the main body portion is provided at predetermined intervals along the rotation direction of the belt body and has a resistance member formed of a substantially plate-shaped body that receives the fluid pressure of the working fluid, so that the working pressure from the working fluid can be efficiently reduced. Can be pressured. At this time, since the belt body can be driven along the flow direction of the working fluid, as described above, the driving starts from the first rotating body located on the upstream side of the working fluid, and accordingly, the downstream of the working fluid is started. The second rotating body located on the side is driven. Thus, for example, by connecting the generator to either the first rotating shaft of the first rotating body or the second rotating shaft of the second rotating body, power can be efficiently generated.
　また、第１の回転軸、第２の回転軸の何れか一方にシャフト部を介して接続された発電機を備えることにより、流体圧により回転した第１の回転体、又は第２の回転体の回転力を、シャフト部を介して発電機に伝達することができる。 In addition, by providing a generator connected to one of the first rotating shaft and the second rotating shaft via a shaft portion, the first rotating body or the second rotating body rotated by fluid pressure Can be transmitted to the generator via the shaft portion.
　また流体駆動装置が、ベルト体の往路側に位置する抵抗部材が露出可能な開口部が形成され、本体部の一部を収納可能なカバー部を備える場合には、本体部の大半の範囲がカバー部により被覆されるため、流体駆動装置が作動流体中に設置された際に、作動流体中に浮遊するゴミ等の異物から本体部を保護することができる。また、ベルト体の往路側に位置する抵抗部材にのみ作動流体が受圧されるため、作動流体によるベルト体を効率的に回転させることができる。 When the fluid driving device has an opening for exposing the resistance member located on the outward path side of the belt body and includes a cover that can store a part of the main body, most of the range of the main body is limited. Since the fluid driving device is installed in the working fluid, the main body can be protected from foreign matters such as dust floating in the working fluid when the fluid driving device is installed in the working fluid. Further, since the working fluid is received only by the resistance member located on the outward path side of the belt, the belt can be efficiently rotated by the working fluid.
　また、第２の回転体よりも径の小さい第１の回転体にシャフト部を介して発電機が接続されている場合には、発電機が接続された第１の回転体を第２の回転体よりも相対的に高速で回転させることができるため、効率的に発電が可能となる。 When a generator is connected to the first rotating body having a smaller diameter than the second rotating body via a shaft portion, the first rotating body to which the generator is connected is connected to the second rotating body. Since it can be rotated at a relatively higher speed than the body, power can be efficiently generated.

In each of the drawings, for convenience of explanation, in a state where the power generation device is installed, a direction going upward from the bottom surface of the power generation device is represented by an upward direction, a direction opposite to the upward direction is represented by a downward direction, an upward direction, and a downward direction. The vertical direction is defined as the vertical direction, and the direction substantially perpendicular to the vertical direction is defined as the horizontal direction.
　［第１の実施形態］
　まず、本発明を適用した第１の実施形態に係る発電装置１ａの全体構成について、図１乃至図３を用いて説明する。発電装置１ａは、主に河川や水路等の水中Ｈに設置し、水圧から得たエネルギーを駆動力に変換して発電機２を作動させて発電するものであり、主に流体駆動装置３と、この流体駆動装置３にシャフト部３１５を介して接続された発電機２、発電機２の出力を図示しない蓄電装置等に出力する出力軸５からから構成されている。なお、各図中の矢印Ｆは水の流れ方向を示す。 [First Embodiment]
First, an overall configuration of a power generator 1a according to a first embodiment to which the present invention is applied will be described with reference to FIGS. The power generation device 1a is installed mainly in underwater H such as a river or a water channel, converts energy obtained from water pressure into driving force to operate the generator 2, and generates power. The fluid drive device 3 includes a power generator 2 connected to the fluid drive device 3 via a shaft 315, and an output shaft 5 for outputting the output of the power generator 2 to a power storage device (not shown). In addition, the arrow F in each figure shows the flow direction of water.
　ここで、必ずしも、発電装置１ａは作動流体として水を利用した水力発電機である必要はない。例えば大気中に設置し、風圧から得たエネルギーを駆動力に変換して発電機２を作動させる風力発電機として使用することも可能である。なお、以後の本発明の実施形態においては、説明の便宜上、水流を利用した水力発電機に係るものについて説明する。 Here, the power generator 1a does not necessarily need to be a hydroelectric generator using water as a working fluid. For example, it can be installed in the atmosphere and used as a wind power generator that operates the generator 2 by converting energy obtained from wind pressure into driving force. In the following embodiments of the present invention, for convenience of description, a description will be given of a hydraulic power generator using a water flow.
　流体駆動装置３は水圧から得たエネルギーを駆動力に変換して発電機２に伝える本体部３１と、本体部３１の一部を被覆するカバー部３２から構成されている。 The fluid driving device 3 includes a main body 31 that converts energy obtained from water pressure into driving force and transmits the driving force to the generator 2, and a cover 32 that covers a part of the main body 31.
　本体部３１は、第１の回転体３１１、第２の回転体３１２、第１の回転体３１１と第２の回転体３１２に架設される無端状のベルト体３１３、及びベルト体３１３の外周面に所定の間隔で設置された抵抗部材３１４から構成されている。 The main body 31 includes a first rotating body 311, a second rotating body 312, an endless belt body 313 bridged between the first rotating body 311 and the second rotating body 312, and an outer peripheral surface of the belt body 313. And a resistance member 314 provided at a predetermined interval.
　略同一の大きさである第１の回転体３１１と第２の回転体３１２は、発電装置１ａを水底である設置面Ｇに設置した状態において、その回転軸が設置面Ｇに対して略平行で、かつ第１の回転体３１１の回転軸と第２の回転体３１２の回転軸が略平行となるように所定の間隔だけ離間して配置されている。 The first rotating body 311 and the second rotating body 312 having substantially the same size have their rotation axes substantially parallel to the installation surface G in a state where the power generator 1a is installed on the installation surface G which is a water bottom. And the rotation axis of the first rotation body 311 and the rotation axis of the second rotation body 312 are spaced apart from each other by a predetermined distance so as to be substantially parallel to each other.
　ここで、必ずしも、回転体として第１の回転体３１１、及び第２の回転体３１２からのみ構成されている必要はない。例えば、使用するベルト体３１３の長さに応じて第１の回転体３１１と第２の回転体３１２の間に図示しない第３の回転体、或いはそれ以上の回転体を複数設置してもよい。 Here, it is not always necessary that the first rotating body 311 and the second rotating body 312 only include the rotating body. For example, a third rotating body (not shown) or a plurality of rotating bodies (not shown) may be provided between the first rotating body 311 and the second rotating body 312 according to the length of the belt body 313 to be used. .
　また、必ずしも、第１の回転体３１１と第２の回転体３１２は略同一の大きさである必要はない。例えば、第１の回転体３１１を第２の回転体３１２に対して小径としたり、第２の回転体３１２を第１の回転体３１１に対して小径とするように、第１の回転体３１１と第２の回転体３１２を異なる大きさに設定することもできる。即ち、第１の回転体３１１と第２の回転体３１２の一方を小径とすることで、小径とした回転体の回転数を相対的に高めることができる。従って、小径とした回転体にシャフト部３１５を介して発電機２を接続することで、より効率的に発電機２を駆動させることができる。 In addition, the first rotating body 311 and the second rotating body 312 do not necessarily have to be approximately the same size. For example, the first rotating body 311 has a smaller diameter than the second rotating body 312 or the first rotating body 311 has a smaller diameter than the first rotating body 311. And the second rotating body 312 can be set to different sizes. That is, by making one of the first rotating body 311 and the second rotating body 312 a small diameter, the rotation speed of the small rotating body can be relatively increased. Therefore, by connecting the generator 2 to the small-diameter rotating body via the shaft portion 315, the generator 2 can be driven more efficiently.
　ベルト体３１３は無端状で多層構造のゴム部材から構成され、第１の回転体３１１と第２の回転体３１２の間に架け渡され、図３（ａ）において紙面に向かって反時計回り、即ち第１の回転体３１１から第２の回転体３１２に向かう往路側Ａ、第２の回転体３１２から第１の回転体３１１に向かう復路側Ｂに向けて周回可能なように回転力を伝達する。なお、ベルト体３１３の内周面と第１の回転体３１１、及び第２の回転体３１２の外周面には凹凸部が形成され、噛合い可能なように構成されていてもよい。 The belt body 313 is formed of a rubber member having an endless multi-layered structure, and is bridged between the first rotating body 311 and the second rotating body 312. In FIG. That is, the rotational force is transmitted so as to be able to circulate from the first rotator 311 toward the second rotator 312 on the outward path A and from the second rotator 312 on the return path B toward the first rotator 311. I do. In addition, the inner peripheral surface of the belt body 313 and the outer peripheral surfaces of the first rotating body 311 and the second rotating body 312 may be formed with irregularities so that they can mesh with each other.
　ここで、必ずしも、第１の回転体３１１、第２の回転体３１２の外周面に形成された凹凸部と、ベルト体の内周面に形成された凹凸部とが噛合うように構成されている必要はなく、噛合い面のない第１の回転体３１１、第２の回転体３１２、及びベルト体３１３を使用してもよい。但し、第１の回転体３１１、第２の回転体３１２、及びベルト体３１３が凹凸部からなる噛合い面を構成することにより、第１の回転体３１１と第２の回転体３１２に対するベルト体３１３の滑りを無くし、ベルト体３１３の回転力を第１の回転体３１１と第２の回転体３１２に対して損失なく伝達することができるため、発電機２の発電効率を高めることができる。 Here, it is not always necessary that the uneven portion formed on the outer peripheral surface of the first rotating body 311 and the second rotating body 312 and the uneven portion formed on the inner peripheral surface of the belt body mesh with each other. The first rotating body 311, the second rotating body 312, and the belt body 313 having no meshing surface need not be provided. However, when the first rotating body 311, the second rotating body 312, and the belt body 313 form a meshing surface including an uneven portion, the belt body for the first rotating body 311 and the second rotating body 312 is formed. Since the slip of the belt 313 can be eliminated, and the rotational force of the belt 313 can be transmitted to the first rotating body 311 and the second rotating body 312 without loss, the power generation efficiency of the generator 2 can be increased.
　また、必ずしも、ベルト体３１３は多層構造のゴム部材から構成されている必要はない。例えば、その他の合成樹脂材や金属製のチェーンベルトから構成されていてもよい。 ベ ル ト In addition, the belt body 313 does not necessarily need to be formed of a rubber member having a multilayer structure. For example, it may be composed of another synthetic resin material or a metal chain belt.
　抵抗部材３１４は、略板状体であって、ベルト体３１３の外周面上にベルト体３１３の円周方向に沿って所定の間隔ごと複数設けられている。抵抗部材３１４は、図３（ｂ）に示すように、ベルト体３１３の外周に直接取り付けられた基部３１４ａと、基端がコイルバネ３１４ｃを介して基部３１４ａに取り付けられた受圧部３１４ｂから構成されている。 The resistance member 314 is a substantially plate-like body, and is provided on the outer peripheral surface of the belt body 313 at a plurality of predetermined intervals along the circumferential direction of the belt body 313. As shown in FIG. 3B, the resistance member 314 includes a base 314a directly attached to the outer periphery of the belt body 313, and a pressure receiving part 314b whose base end is attached to the base 314a via a coil spring 314c. I have.
　コイルバネ３１４ｃは、一端が受圧部３１４ｂに、他端が基部３１４ａに係止され、受圧部３１４ｂと基部３１４ａのそれぞれに付勢力が付与されている。これにより、通常状態において受圧部３１４ｂはベルト体３１３に対して鉛直方向に立設する起立位置となるとともに、外力が加えられることにより起立位置からベルト体３１３に対して略平行位置である倒伏位置に可動自在となるように構成されている。 The coil spring 314c has one end locked to the pressure receiving portion 314b and the other end locked to the base 314a, and a biasing force is applied to each of the pressure receiving portion 314b and the base 314a. Thus, in the normal state, the pressure receiving portion 314b becomes a standing position that stands vertically with respect to the belt body 313, and a falling position that is substantially parallel to the belt body 313 from the standing position when an external force is applied. It is configured to be freely movable.
　ここで、必ずしも、抵抗部材３１４は板状体から構成されている必要はない。例えば、図４に示すように抵抗部材３１４として、水流に向かって開口部３１４ｄが形成されたメッシュ状の袋体３１４ｅからなり、ベルト体３１３の往路側Ａに位置する状態において、水圧を受けた際に起立位置に跳ね上がり、ベルト体３１３の復路側Ｂに位置する際には、水圧により倒伏位置となるように構成されていてもよい。 Here, the resistance member 314 does not necessarily need to be formed of a plate. For example, as shown in FIG. 4, the resistance member 314 is formed of a mesh-shaped bag body 314 e having an opening 314 d formed toward the water flow, and receives a water pressure in a state where the resistance member 314 is located on the outward path side A of the belt body 313. At this time, when the belt body 313 jumps up to the upright position and is located on the return path side B of the belt body 313, the belt body 313 may be configured to be in the lying position by water pressure.
　また、必ずしも、受圧部３１４ｂはコイルバネ３１４ｃにより基部３１４ａに対して起立位置となる方向に付勢されている必要はなく、設置する水中の状況に応じて適宜変更することができる。例えば、水流の流れが速く、水圧が比較的大きな水中Ｈに設置する場合には、受圧部３１４ｂはコイルバネ３１４ｃにより倒伏位置となる方向に付勢されており、抵抗部材３１４がベルト体３１３の往路側Ａに位置する状態において、水圧を受けることにより起立位置となるように構成されていてもよい。 圧 Also, the pressure receiving portion 314b does not necessarily need to be urged by the coil spring 314c in the direction in which the pressure receiving portion 314b stands up relative to the base portion 314a, and can be appropriately changed according to the condition of the installed water. For example, when the water flow is fast and the water pressure is relatively high, the pressure receiving portion 314b is urged by the coil spring 314c in the direction of the falling position, and the resistance member 314 is moved outward of the belt body 313. In the state located on the side A, it may be configured to be in the upright position by receiving water pressure.
　カバー部３２は、先端部分が傾斜した略船型であるとともに、上面側に開口部３２１が形成され、下面側に底部３２２を有する断面略Ｕ字状であって、少なくともベルト体３１３の往路側Ａに位置する抵抗部材３１４が、カバー部３２の外部に露出するように本体部３１の一部を被覆するものとなっている。 The cover portion 32 has a substantially U-shaped cross section having a top portion with an opening 321 formed on the upper surface side and a bottom portion 322 on the lower surface side, and at least a forward A side of the belt body 313. Is formed to cover a part of the main body 31 so as to be exposed to the outside of the cover 32.
　これにより、ベルト体３１３の往路側Ａに位置する抵抗部材３１４は、ベルト体３１３の回転方向の水圧を受けてベルト体３１３を円滑に回転させることができる。一方、復路側Ｂに位置する抵抗部材３１４は、水圧を直接的に受圧することがないため、ベルト体３１３の回転が妨げられず、ベルト体３１３の回転効率、及び発電機２の発電効率を高めることができる。 Accordingly, the resistance member 314 located on the outward path side A of the belt body 313 can receive the water pressure in the rotation direction of the belt body 313 and smoothly rotate the belt body 313. On the other hand, since the resistance member 314 located on the return side B does not directly receive the water pressure, the rotation of the belt body 313 is not hindered, and the rotation efficiency of the belt body 313 and the power generation efficiency of the generator 2 are reduced. Can be enhanced.
　さらに、水の流れにより運ばれるゴミ等の異物が第１の回転体３１１や第２の回転体３１２に付着したり、或いは絡まったりすることを防止し、第１の回転体３１１、及び第２の回転体３１２の回転効率を高めることができる。 Further, foreign substances such as dust carried by the flow of water are prevented from adhering to or entangled with the first rotating body 311 and the second rotating body 312, and the first rotating body 311 and the second rotating body 311 are prevented from being entangled. The rotation efficiency of the rotator 312 can be increased.
　ここで、必ずしも、カバー部３２は略船型である必要はない。例えば、半楕円形状、流線形状等、どのような形状であってもよい。但し、発明者が検討した結果、カバー部３２の形状として略船型とすることにより、カバー部３２に作用する抵抗力を弱め、水流によるカバー部３２の破損等を防止することができた。 Here, the cover 32 does not necessarily have to be substantially boat-shaped. For example, any shape such as a semi-elliptical shape and a streamline shape may be used. However, as a result of the study by the inventor, the resistance acting on the cover 32 was reduced by making the shape of the cover 32 substantially boat-shaped, and damage to the cover 32 due to the water flow could be prevented.
　また、必ずしも、カバー部３２は断面略Ｕ字状である必要はない。例えば水流を直接受ける本体部３１の前面側のみを被覆するような構成、或いは本体部３１の前後面のみを被覆するような形状であってもよい。 カ バ ー Also, the cover part 32 does not necessarily need to have a substantially U-shaped cross section. For example, a configuration that covers only the front side of the main body 31 that directly receives the water flow, or a shape that covers only the front and rear surfaces of the main body 31 may be used.
　カバー部３２の底部３２２とベルト体３１３の復路側Ｂは略近接する位置関係となっている。即ち、図３に示すように、ベルト体３１３が周回し、往路側Ａに位置する抵抗部材３１４が復路側Ｂに移動すると、ベルト体３１３に対して起立位置である抵抗部材３１４は、その先端部がカバー部３２の底部３２２と接触しながら、コイルバネ３１４ｃにより倒伏位置に折り畳まれるように構成されている。なお、理解しやすいため、図３中においてカバー部３２の図示は省略している。 (4) The bottom portion 322 of the cover 32 and the return path B of the belt body 313 are in a substantially close positional relationship. That is, as shown in FIG. 3, when the belt member 313 goes around and the resistance member 314 located on the forward path A moves to the return path B, the resistance member 314 which is in the standing position with respect to the belt member 313 has its tip end. The portion is configured to be folded to the lying position by the coil spring 314c while contacting the bottom portion 322 of the cover portion 32. The illustration of the cover 32 is omitted in FIG. 3 for easy understanding.
　ここで、必ずしも、抵抗部材３１４はベルト体３１３の復路側Ｂにおいてカバー部３２の底部３２２と接触して倒伏位置となるように構成されている必要はない。例えば、ベルト体３１３の復路側Ｂに位置するカバー部３２の底部３２２と、起立位置にある抵抗部材３１４の先端が十分な間隔が形成されており、ベルト体３１３の復路側Ｂに位置する抵抗部材３１４が起立位置を維持するように構成されていてもよい。このような場合もで、ベルト体３１３の復路側Ｂに位置する抵抗部材３１４は、カバー部３２により水圧が直接作用しないため、ベルト体３１３の回転が妨げられることもない。 Here, the resistance member 314 does not necessarily need to be configured to contact the bottom portion 322 of the cover portion 32 on the return path side B of the belt body 313 to be in the lying position. For example, a sufficient interval is formed between the bottom 322 of the cover portion 32 located on the return path B of the belt body 313 and the tip of the resistance member 314 in the upright position, and the resistance located on the return path B of the belt body 313 is increased. The member 314 may be configured to maintain the upright position. Even in such a case, since the water pressure is not directly applied to the resistance member 314 located on the backward path side B of the belt body 313 by the cover portion 32, the rotation of the belt body 313 is not hindered.
　カバー部３２の側面には、第１の回転体３１１、及び第２の回転体３１２の回転軸に略対応する位置に小径の孔部（符号を付さない）が形成されている。この孔部には、第１の回転体３１１、及び第２の回転体３１２のそれぞれの回転軸に貫通されたシャフト部３１５が挿通され、シャフト部３１５の先端には鉛直方向に延在する支柱４１を含む基台４を有している。シャフト部３１５と支柱４１はボルト、ナット等の公知の固定手段により固定されており、これにより本体部３１とカバー部３２は一体化されている。 小 On the side surface of the cover 32, a small-diameter hole (not denoted) is formed at a position substantially corresponding to the rotation axis of the first rotating body 311 and the second rotating body 312. The shaft portion 315 penetrated through the respective rotating shafts of the first rotating body 311 and the second rotating body 312 is inserted into the hole, and a column extending in the vertical direction is provided at the tip of the shaft portion 315. It has a base 4 including 41. The shaft portion 315 and the support 41 are fixed by known fixing means such as bolts and nuts, so that the main body 31 and the cover 32 are integrated.
　ここで、必ずしも、支柱４１を含む基台４を有している必要はない。但し、基台４を有することにより、発電装置１ａを水中Ｈに設置する際に、設置面Ｇに対して安定的に設置することができるとともに、基台４の一部を設置面Ｇに埋設することで、比較的水位の浅い水中Ｈにも設置が可能となる。 Here, it is not always necessary to have the base 4 including the column 41. However, by having the base 4, when the power generator 1 a is installed in the water H, it can be stably installed on the installation surface G, and a part of the base 4 is embedded in the installation surface G. By doing so, it is possible to set up even in the water H having a relatively shallow water level.
　また、必ずしも、第１の回転体３１１、及び第２の回転体３１２の回転軸から突出するシャフト部３１５が、カバー部３２に形成された孔部に挿通されて本体部３１とカバー部３２が一体化される必要はない。例えば、図５に示すように、第１の回転体３１１、及び第２の回転体３１２の回転軸から突出する短尺のシャフト部３１５に支柱４２が接続され、カバー部３２の底部３２２にボルト、ナット等の公知の固定手段により取り付けられるように構成してもよい。 Also, the shaft 315 protruding from the rotation axis of the first rotating body 311 and the second rotating body 312 is necessarily inserted into the hole formed in the cover 32 so that the main body 31 and the cover 32 are It need not be integrated. For example, as shown in FIG. 5, the column 42 is connected to a short shaft portion 315 protruding from the rotation axis of the first rotating body 311 and the second rotating body 312, and a bolt is attached to the bottom 322 of the cover 32. You may comprise so that it may be attached by well-known fixing means, such as a nut.
　なお、図５に示すような形態の場合、支柱４１をカバー部３２の底部３２２に一体化させて取り付けるように構成してもよい。 In the case of the form shown in FIG. 5, the column 41 may be integrated with and attached to the bottom 322 of the cover 32.
　発電機２は、第１の回転体３１１、又は第２の回転体３１２から突出するシャフト部３１５に接続されている。このように構成することで、第１の回転体３１１、又は第２の回転体３１２と一体に回転するシャフト部３１５の回転力が発電機２に伝達され、発電機２による発電が開始されるようになっている。 The generator 2 is connected to a shaft 315 protruding from the first rotating body 311 or the second rotating body 312. With this configuration, the rotating force of the shaft portion 315 that rotates integrally with the first rotating body 311 or the second rotating body 312 is transmitted to the generator 2, and power generation by the generator 2 is started. It has become.
　次に、本発明の実施形態に係る発電装置１ａの作動について説明する。 Next, the operation of the power generator 1a according to the embodiment of the present invention will be described.
　水路や川等の水中Ｈに設置された発電装置１ａは、先ず、ベルト体３１３に対して起立位置にあり、カバー部３２から露出しているベルト体３１３の往路側Ａに位置する抵抗部材３１４の受圧部３１４ｂにおいて水流による水圧を受ける。 The power generating device 1a installed in the underwater H such as a waterway or a river is in a standing position with respect to the belt body 313, and the resistance member 314 located on the outward path side A of the belt body 313 exposed from the cover portion 32. At the pressure receiving portion 314b.
　抵抗部材３１４の受圧部３１４ｂが水圧を受けることにより、ベルト体３１３が回転を開始し、それに伴い、第１の回転体３１１が回転し始める。 ベ ル ト When the pressure receiving portion 314b of the resistance member 314 receives the water pressure, the belt body 313 starts rotating, and accordingly, the first rotating body 311 starts rotating.
　次に、ベルト体３１３による回転力が第１の回転体３１１から第２の回転体３１２に伝達され、第１の回転体３１１の駆動に従動するように第２の回転体３１２が回転する。 Next, the rotational force of the belt 313 is transmitted from the first rotator 311 to the second rotator 312, and the second rotator 312 rotates so as to follow the driving of the first rotator 311.
　ベルト体３１３の回転に伴い、ベルト体３１３の外周に設置された抵抗部材３１４がベルト体３１３の往路側Ａから復路側Ｂへと順次移動していく。このとき、前述した通り、ベルト体３１３の復路側Ｂに移動した抵抗部材３１４は、抵抗部材３１４の先端がカバー部３２の底部３２２と接触しながら起立位置から第２の回転体３１２側へと倒伏する。 抵抗 With the rotation of the belt 313, the resistance member 314 installed on the outer periphery of the belt 313 sequentially moves from the forward side A to the backward side B of the belt 313. At this time, as described above, the resistance member 314 that has moved to the return path side B of the belt body 313 moves from the standing position to the second rotating body 312 side while the tip of the resistance member 314 contacts the bottom 322 of the cover 32. To fall down.
　ベルト体３１３の回転数が上がるにつれて、第１の回転体３１１、及び第２の回転体３１２の回転数も徐々に上昇する。その際、例えば発電機２が第１の回転体３１１に接続されたシャフト部３１５に接続されている場合には、第１の回転体３１１の回転軸に接続されたシャフト部３１５の回転力が発電機２に伝達され、発電機２による発電が行われる。 に つ れ て As the number of rotations of the belt body 313 increases, the number of rotations of the first rotator 311 and the second rotator 312 also gradually increases. At this time, for example, when the generator 2 is connected to the shaft 315 connected to the first rotating body 311, the torque of the shaft 315 connected to the rotating shaft of the first rotating body 311 is reduced. The power is transmitted to the generator 2 and power is generated by the generator 2.
　［第２の実施形態］
　次に本発明の第２の実施形態に係る発電装置１ｂについて、図６に基づいて説明する。なお、第１の実施形態と重複する部分については同一符号を付すとともに、重複する説明については省略する。 [Second embodiment]
Next, a power generator 1b according to a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
　図６に示すように、第２の実施形態に係る発電装置１ｂは、流体駆動装置３が水中Ｈから水面Ｌの上方に向かって所定の傾斜角（例えば略４５度）を有するように設置面Ｇに設置されている。具体的には、第１の回転体３１１を支持するアンカー支柱４１よりも、第２の回転体３１２を支持するアンカー支柱４１が相対的に長く、第１の回転体３１１が水中Ｈに、第２の回転体３１２が水面Ｌの上方にそれぞれ位置するように設置面Ｇに設置されている。 As shown in FIG. 6, the power generation device 1b according to the second embodiment has an installation surface such that the fluid driving device 3 has a predetermined inclination angle (for example, approximately 45 degrees) from the underwater H to above the water surface L. It is installed in G. Specifically, the anchor strut 41 that supports the second rotating body 312 is relatively longer than the anchor strut 41 that supports the first rotating body 311, and the first rotating body 311 is underwater H, The two rotating bodies 312 are installed on the installation surface G so as to be located above the water surface L, respectively.
　このとき、流体駆動装置３は水流に対して略４５度の角度で傾斜して設置され、ベルト体３１３は、往路側Ａにおいて水中Ｈから水面Ｌに向かう方向、復路側Ｂにおいて水面Ｌの上方から水中Ｈに向かう方向に周回する。 At this time, the fluid driving device 3 is installed at an angle of approximately 45 degrees with respect to the water flow, and the belt body 313 is directed from the underwater H to the water surface L on the outward path A, and above the water surface L on the return path B. Orbiting in the direction toward underwater H from.
　また、カバー部３２は、復路側Ｂの全体と、水面Ｌよりも上方であって水中Ｈから露出する往路側Ａの一部の範囲を被覆するように構成されている。 {Circle around (2)} The cover portion 32 is configured to cover the whole of the return path B and a part of the forward path A which is above the water surface L and is exposed from the underwater H.
　このように構成することで、ベルト体３１３の往路側Ａの位置において起立位置にある抵抗部材３１４は、水流に対して一定の迎角を有することになる。従って、受圧部３１４ｂで水圧を受圧した抵抗部材３１４には、ベルト体３１３の周回方向への力が作用することになり、ベルト体３１３をより効率的に回転させることができる。 構成 With this configuration, the resistance member 314 in the standing position at the position of the outward path A of the belt body 313 has a constant angle of attack with respect to the water flow. Therefore, a force in the circumferential direction of the belt body 313 acts on the resistance member 314 that has received the water pressure by the pressure receiving portion 314b, and the belt body 313 can be rotated more efficiently.
　このときカバー部３２は、ベルト体３１３の往路側Ａの一部を被覆するように構成されているため、水面Ｌから出た抵抗部材３１４はカバー部３２と接触することで倒伏位置となり、ベルト体３１３の周回に際しての抵抗を低減することが可能となっている。 At this time, since the cover portion 32 is configured to cover a part of the outward path side A of the belt body 313, the resistance member 314 coming out of the water surface L comes into contact with the cover portion 32 to be in the falling position, and It is possible to reduce the resistance when the body 313 goes around.
　ここで、必ずしも、カバー部３２はベルト体３１３の往路側Ａの一部を被覆するように構成されている必要はない。復路側Ｂのみを被覆するように構成されていてもよい。但し、抵抗部材３１４に作用する抵抗を低減して、ベルト体３１３を効率的に回転させるという観点では、カバー部３２はベルト体３１３の往路側Ａの一部を被覆するように構成されていることが好ましい。 Here, the cover portion 32 does not necessarily need to be configured to cover a part of the forward side A of the belt body 313. It may be configured to cover only the return side B. However, from the viewpoint of reducing the resistance acting on the resistance member 314 and efficiently rotating the belt body 313, the cover part 32 is configured to cover a part of the outward path side A of the belt body 313. Is preferred.
　［第３の実施形態］
　次に第３の実施形態に係る発電装置１ｃについて、図７に基づいて説明する。なお、第１の実施形態と重複する部分については同一符号を付すとともに、重複する説明については省略する。 [Third Embodiment]
Next, a power generator 1c according to a third embodiment will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
　図７に示すように、第３の実施形態に係る発電装置１ｃは、流体駆動装置３のカバー部３２の上面に形成された開口部３２１の周囲（側面の上縁）に、水流を整流する整流板６が設けられている。整流板６は水流の上流側に向けて開口するように構成されているため、水流を抵抗部材３１４に向かうように整流させることができる。従って、より多くの水流を抵抗部材３１４の受圧部３１４ｂに指向させることができるため、抵抗部材３１４の受圧部３１４ｂでより多くの水圧を受けることができ、ベルト体３１３を効率的に回転させることが可能となっている。 As shown in FIG. 7, the power generation device 1c according to the third embodiment rectifies the water flow around the opening 321 (the upper edge of the side surface) formed on the upper surface of the cover 32 of the fluid driving device 3. A current plate 6 is provided. Since the current plate 6 is configured to open toward the upstream side of the water flow, the water flow can be rectified toward the resistance member 314. Therefore, since more water flow can be directed to the pressure receiving portion 314b of the resistance member 314, more water pressure can be received by the pressure receiving portion 314b of the resistance member 314, and the belt body 313 can be rotated efficiently. Is possible.
　ここで、必ずしも、整流板６はカバー部３２の上面に形成された開口部３２１の周囲に取り付ける必要はない。例えば、カバー部３２の先端側に取り付けるように構成してもよい。 Here, it is not always necessary to attach the current plate 6 around the opening 321 formed on the upper surface of the cover 32. For example, you may comprise so that it may be attached to the front-end | tip side of the cover part 32.
　［第４の実施形態］
　次に第４の実施形態に係る発電装置１ｄについて、図８に基づいて説明する。なお、第１の実施形態と重複する部分については同一符号を付すとともに、重複する説明については省略する。 [Fourth embodiment]
Next, a power generator 1d according to a fourth embodiment will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
　第４の実施形態に係る発電装置１ｄは、第１の実施形態に係る発電装置１ａに対して流体駆動装置３のベルト体３１３の往路側Ａ、復路側Ｂの位置が上下反転し、カバー部３２の開口部３２１が鉛直下方に向けて開口するように形成されている点で異なる。即ち、第４の実施形態に係る流体駆動装置３のベルト体３１３は、図８の紙面に向かって時計回りの方向に回転するため、ベルト体３１３の往路側Ａは復路側Ｂに対して鉛直下方側に位置する。そして、カバー部３２は、ベルト体３１３の復路側Ｂに位置する抵抗部材３１４を覆うように、鉛直下方に向けて開口部３２１が形成されるように構成されている。 The power generation device 1d according to the fourth embodiment is different from the power generation device 1a according to the first embodiment in that the positions of the forward path A and the return path B of the belt body 313 of the fluid driving device 3 are turned upside down, and 32 in that the opening 321 is formed so as to open vertically downward. That is, since the belt body 313 of the fluid drive device 3 according to the fourth embodiment rotates clockwise in the direction of the paper of FIG. 8, the forward side A of the belt body 313 is perpendicular to the backward side B. It is located on the lower side. The cover portion 32 is configured such that an opening 321 is formed vertically downward so as to cover the resistance member 314 located on the return path side B of the belt body 313.
　第４の実施形態に係る発電装置１ｄによれば、ベルト体３１３が回転駆動するためには、少なくともベルト体３１３の往路側Ａに位置する抵抗部材３１４が水中Ｈに浸水すればよいため、例えば水位の低い水路等への設置も容易に行うことが可能となる。 According to the power generation device 1d according to the fourth embodiment, in order for the belt member 313 to be driven to rotate, at least the resistance member 314 located on the outward path side A of the belt member 313 may be submerged in the water H. It can be easily installed in a water channel with a low water level.
　また、水面よりも外部に露出する復路側Ｂに位置する抵抗部材３１４はカバー部３２で被覆されるため、水の流れにより運ばれるゴミ等の異物が第１の回転体３１１や第２の回転体３１２に付着したり、絡まったりすることを防止し、第１の回転体３１１、及び第２の回転体３１２の回転効率を高めることができる。 In addition, since the resistance member 314 located on the return path side B exposed to the outside from the water surface is covered with the cover portion 32, foreign substances such as dust carried by the flow of water can be removed by the first rotating body 311 or the second rotating body. It is possible to prevent the first rotating body 311 and the second rotating body 312 from being attached to or entangled with the body 312 and to increase the rotation efficiency.
　［第５の実施形態］
　次に第５の実施形態に係る発電装置１ｅについて、図９に基づいて説明する。なお、第１の実施形態と重複する部分については同一符号を付すとともに、重複する説明については省略する。 [Fifth Embodiment]
Next, a power generator 1e according to a fifth embodiment will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.
　第５の実施形態に係る発電装置１ｅは、図９に示すように、流体駆動装置３が水面Ｌの上方から水中Ｈに向かって所定の傾斜角（例えば略４５度）を有するように設置面Ｇに設置されている。具体的には、第１の回転体３１１を支持するアンカー支柱４１よりも、第２の回転体３１２を支持するアンカー支柱４１が相対的に短く、第１の回転体３１１が水面Ｌよりも上方、第２の回転体３１２が水中Ｈにそれぞれ位置するように地面Ｇに設置されている。 As shown in FIG. 9, the power generation device 1e according to the fifth embodiment has an installation surface such that the fluid driving device 3 has a predetermined inclination angle (for example, approximately 45 degrees) from above the water surface L toward the water H. It is installed in G. Specifically, the anchor support 41 supporting the second rotary body 312 is relatively shorter than the anchor support 41 supporting the first rotary body 311, and the first rotary body 311 is located above the water surface L. , The second rotating body 312 is installed on the ground G so as to be located in the water H.
　このとき、流体駆動装置３は水流に対して略４５度の角度で傾斜して設置され、ベルト体３１３は、往路側Ａにおいて水面Ｌの上方から水中Ｈに向かう方向、復路側Ｂにおいて水中Ｈから水面Ｌの上方に向かう方向に周回する。 At this time, the fluid driving device 3 is installed so as to be inclined at an angle of approximately 45 degrees with respect to the water flow, and the belt body 313 is directed toward the water H from above the water surface L on the outward path A and underwater H on the return path B. From the water surface L upward.
　また、カバー部３２は、水面Ｌよりも上方に突出する往路側Ａ、及び復路側Ｂの一部の範囲を被覆するように構成されている。 {Circle around (2)} The cover part 32 is configured to cover a partial range of the forward path A and the backward path B that protrude above the water surface L.
　このように構成することで、ベルト体３１３の往路側Ａの位置において起立位置にある抵抗部材３１４は、水流に対して一定の迎角を有することになる。従って、受圧部３１４ｂで水圧を受圧した抵抗部材３１４には、ベルト体３１３の周回方向への力が作用することになり、ベルト体３１３をより効率的に回転させることができる。 With this configuration, the resistance member 314 in the standing position at the position of the outward path A of the belt body 313 has a constant angle of attack with respect to the water flow. Therefore, a force in the circumferential direction of the belt body 313 acts on the resistance member 314 that has received the water pressure by the pressure receiving portion 314b, and the belt body 313 can be rotated more efficiently.
　ここで、必ずしも、カバー部３２は、水面Ｌよりも上方に突出する往路側Ａ、及び復路側Ｂの一部を被覆するように構成されている必要はない。例えば、復路側Ｂの全体を被覆するように構成されていてもよい。 Here, the cover part 32 does not necessarily need to be configured to cover a part of the forward path A and the return path B that project above the water surface L. For example, it may be configured so as to cover the entire return path B.
　以上のように、本発明を適用した流体駆動装置、及び発電装置は、水力等の自然エネルギーを効率的に電気エネルギーに変換して発電効率を高めることができるものとなっている。 As described above, the fluid drive device and the power generation device to which the present invention is applied can efficiently convert natural energy such as hydraulic power into electric energy to increase power generation efficiency.
