そして、水上に設置されるフロートタイプの太陽光発電装置において、太陽光発電パネル背面の吸熱板に接続された放熱板をフロートから水中に入れることで、太陽光発電パネルを冷却するものが、特許文献２に提案されている。
また、フロート下の水をフロート中央部の穴から吸引して噴出させることによりフロート上の太陽光発電パネルに流下させることで、太陽光発電パネルを冷却するものが、特許文献３に提案されている。 In addition, since a large area is required for the installation of large-scale mega solar, the number of installations on the water is increasing.
Then, in the float type photovoltaic power generation device installed on the water, the one that cools the photovoltaic power generation panel by putting the heat radiating plate connected to the heat absorbing plate on the back of the photovoltaic power generation panel into the water from the float is patented. It is proposed in Document 2.
Further, Patent Document 3 proposes a method of cooling a photovoltaic power generation panel by sucking water under the float from a hole in the center of the float and ejecting it to flow down the photovoltaic power generation panel on the float. There is.

しかしながら、特許文献１のような太陽用発電パネル表面への散水方式や、特許文献２のような太陽光発電パネル背面の吸熱板に接続された放熱板をフロートから水中に入れる冷却構造や、特許文献３のようなフロート下の水をフロート中央部の穴から吸引して噴出させることによりフロート上の太陽光発電パネルに流下させる冷却方式では、冷却性能が不十分であった。 However, a method of sprinkling water on the surface of a photovoltaic power generation panel as in Patent Document 1, a cooling structure in which a heat radiation plate connected to a heat absorbing plate on the back surface of the photovoltaic power generation panel as in Patent Document 2 is put into water from a float, and a patent. The cooling performance was insufficient in the cooling method as in Document 3 in which the water under the float was sucked from the hole in the center of the float and ejected to flow down to the photovoltaic power generation panel on the float.

以下、図を参照して本発明を実施するための形態を詳細に説明する。
（実施形態１）
図１及び図２は本発明を適用した水上太陽光発電システムの一実施形態の概略構成を示すもので、１は架台、２は太陽光発電パネル、３は冷却水通路、４はポンプ、５は貯水タンク、６は発電用水車、７は発電機、８・９はクラッチ、１０は動力伝達装置である。 Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
1 and 2 show a schematic configuration of an embodiment of a floating photovoltaic power generation system to which the present invention is applied, where 1 is a stand, 2 is a photovoltaic power generation panel, 3 is a cooling water passage, 4 is a pump, and 5 is. Is a water storage tank, 6 is a water turbine for power generation, 7 is a generator, 8 and 9 are clutches, and 10 is a power transmission device.

図示のように、池、湖、海等の水上の架台１の上には、太陽光発電パネル２が斜めに設置されている。架台１は、図示しないが、水底に着く足付きのものである。
この太陽光発電パネル２は、多数の太陽電池モジュールを縦横方向に並べて一体化した大面積のもので、その受光面を太陽の方向に向けて斜めに設置されており、受光面の背面の全面に沿ってハウジングにより囲まれた冷却水通路３が形成されている。
この冷却水通路３には、太陽光発電パネル２の背面に取り付けられた図略の吸熱板に繋げた縦方向に沿った強度確保用リブを兼ねた図略の放熱板が横方向に間隔を開けて並べられている。 As shown in the figure, the photovoltaic power generation panel 2 is diagonally installed on the gantry 1 on the water such as a pond, a lake, or the sea. Although not shown, the gantry 1 has feet that reach the bottom of the water.
The photovoltaic cell panel 2 has a large area in which a large number of solar cell modules are arranged in the vertical and horizontal directions and integrated, and the light receiving surface thereof is installed diagonally toward the sun, and the entire back surface of the light receiving surface is installed. A cooling water passage 3 surrounded by a housing is formed along the above.
In the cooling water passage 3, a heat radiating plate of the drawing which is connected to a heat absorbing plate of the drawing attached to the back surface of the photovoltaic power generation panel 2 and which also serves as a rib for ensuring strength along the vertical direction is spaced laterally. It is open and lined up.

そして、架台１の下には、ポンプ４を水中に設置する一方、太陽光発電パネル２の上部に設けた冷却水入口に断熱性の貯水タンク５を設けている。
この貯水タンク５に、ポンプ４で揚水して貯水し、すなわち、太陽光発電パネル２を冷却するための水を貯めておく。貯水タンク５ヘの水は、架台１下方で直射日光が当たらない冷たい水をポンプ４で揚水する。 Then, under the gantry 1, the pump 4 is installed underwater, while the heat-insulating water storage tank 5 is provided at the cooling water inlet provided above the photovoltaic power generation panel 2.
In the water storage tank 5, water is pumped up and stored, that is, water for cooling the photovoltaic power generation panel 2 is stored. As for the water to the water storage tank 5, cold water that is not exposed to direct sunlight is pumped by the pump 4 below the gantry 1.

また、冷却水通路３の太陽光電池パネル２下部に位置する冷却水出口には、ペルトン水車による発電用水車６を取り付ける。この発電用水車６は、図２に示したように、冷却水通路３の太陽光電池パネル２の下辺部に沿って開口する冷却水出口に沿って軸線方向を配置する。
なお、冷却水出口には図略の絞りを設けて、その絞りで発生するジェット水流がペルトン水車のバケットに当たって、発電用水車６が効率よく回転するように構成する。 Further, a water turbine 6 for power generation by a Pelton turbine is attached to a cooling water outlet located at the lower part of the solar cell panel 2 of the cooling water passage 3. As shown in FIG. 2, the water turbine 6 is arranged in the axial direction along the cooling water outlet that opens along the lower side of the solar cell panel 2 of the cooling water passage 3.
A throttle (not shown) is provided at the cooling water outlet so that the jet water flow generated by the throttle hits the bucket of the Pelton turbine and the water turbine 6 for power generation rotates efficiently.

さらに、発電用水車６の軸部の一端（図２では左端）に発電機７を接続し、発電用水車６と発電機７との間にクラッチ８を設ける。 Further, a generator 7 is connected to one end (left end in FIG. 2) of the shaft portion of the water turbine 6 for power generation, and a clutch 8 is provided between the water turbine 6 for power generation and the generator 7.

また、発電用水車６の軸部の他端（図２では右端）とポンプ４の間にクラッチ９及び動力伝達装置１０を設ける。
すなわち、動力伝達装置１０は、図示例では、ポンプ４を回転駆動させるベルトプーリ機構で、その入力軸と発電用水車６との間にクラッチ９を設ける。 Further, a clutch 9 and a power transmission device 10 are provided between the other end of the shaft portion of the water turbine 6 for power generation (the right end in FIG. 2) and the pump 4.
That is, in the illustrated example, the power transmission device 10 is a belt pulley mechanism that rotationally drives the pump 4, and a clutch 9 is provided between the input shaft and the water turbine 6 for power generation.

以上において、架台１上の太陽光発電パネル２の高さを１０ｍ以上とする。
従って、冷却水通路３には１０ｍ以上の水頭差が生じる。 In the above, the height of the photovoltaic power generation panel 2 on the gantry 1 is 10 m or more.
Therefore, a head difference of 10 m or more occurs in the cooling water passage 3.

以上の水上太陽光発電システムの運用時において、太陽光発電パネル２の温度が上昇して所定値に達した場合には、太陽光発電パネル２の背面全面に取り付けられた冷却水通路３に貯水タンク５の水を流下させることで、太陽光発電パネル２の背面全面を冷却する。
ここで、初期のポンプ４の駆動は、太陽光発電パネル２で発電された電力を利用して行う。すなわち、太陽光発電パネル２の冷却が必要な時は、太陽光発電パネル２が発電状態にあるので、破線で示したように、その余剰電力を用いてポンプ４を駆動する。この時、クラッチ９を切っておく。 When the temperature of the photovoltaic power generation panel 2 rises and reaches a predetermined value during the operation of the above floating photovoltaic power generation system, water is stored in the cooling water passage 3 attached to the entire back surface of the photovoltaic power generation panel 2. By letting the water in the tank 5 flow down, the entire back surface of the photovoltaic power generation panel 2 is cooled.
Here, the initial drive of the pump 4 is performed by using the electric power generated by the photovoltaic power generation panel 2. That is, when the photovoltaic power generation panel 2 needs to be cooled, since the photovoltaic power generation panel 2 is in the power generation state, the pump 4 is driven by using the surplus power as shown by the broken line. At this time, the clutch 9 is disengaged.

そして、ポンプ４で揚水された貯水タンク５から太陽光発電パネル２の背面全面の冷却水通路３を流下して発電用水車６が回転すると、クラッチ９を接続状態にして、発電用水車６の回転によりクラッチ９及び動力伝達装置１０を経てポンプ４を駆動する。
すなわち、太陽光発電パネル２の背面全面の冷却水通路３を流下してきた水の運動エネルギーを発電用水車６で吸収し、その発電用水車６の回転力をポンプ４の動力として利用することで、他からのエネルギーをほとんど必要とせずに揚水を行う。 Then, when the water turbine 6 rotates by flowing down the cooling water passage 3 on the entire back surface of the photovoltaic power generation panel 2 from the water storage tank 5 pumped by the pump 4, the clutch 9 is engaged and the water turbine 6 of the power generation is connected. The rotation drives the pump 4 via the clutch 9 and the power transmission device 10.
That is, the kinetic energy of the water flowing down the cooling water passage 3 on the entire back surface of the photovoltaic power generation panel 2 is absorbed by the water turbine 6 for power generation, and the rotational force of the water turbine 6 for power generation is used as the power for the pump 4. , Pumps water with little need for energy from others.

なお、エネルギーが僅かに足らない場合には、太陽光発電パネル２の余剰電力でポンプ４を駆動して揚水を行う。
このように、太陽光発電パネル２の余剰電力を水の位置エネルギーとして蓄え、冷却水通路３に流して下部の発電用水車６で発電することもできる。これにより、蓄電設備を持たずに、発電量の平滑化も可能である。 If the energy is slightly insufficient, the pump 4 is driven by the surplus power of the photovoltaic power generation panel 2 to pump water.
In this way, the surplus electricity of the photovoltaic power generation panel 2 can be stored as potential energy of water, flowed through the cooling water passage 3, and generated by the water turbine 6 at the lower part. As a result, it is possible to smooth the amount of power generation without having a power storage facility.

以上、実施形態の水上太陽光発電システムによれば、太陽光発電パネル２の背面全面に設けた冷却水通路３に、その上部の入口に設置した貯水タンク５から冷却水を流すことで、水上の太陽光発電パネル２に対する十分な冷却性能を具備することができる。
従って、水上の太陽光発電パネル２による発電効率を高めることができる。 As described above, according to the water-based photovoltaic power generation system of the embodiment, the cooling water is flowed from the water storage tank 5 installed at the upper inlet of the cooling water passage 3 provided on the entire back surface of the photovoltaic power generation panel 2 to the water. It is possible to provide sufficient cooling performance for the photovoltaic power generation panel 2.
Therefore, it is possible to increase the power generation efficiency of the photovoltaic power generation panel 2 on the water.

そして、冷却水通路３の出口に配置した発電用水車６を、太陽光電池パネル２冷却後の水で回転させて、接続状態のクラッチ８を経て発電機７で発電して、売電に供することができる。 Then, the water turbine 6 for power generation arranged at the outlet of the cooling water passage 3 is rotated by the water after cooling the solar cell panel 2, and the generator 7 generates power through the clutch 8 in the connected state to sell the power. Can be done.

（実施形態２）
図３及び図４は実施形態２の水上太陽光発電システムの概略構成を示すもので、前述した実施形態１と同様、２は太陽光発電パネル、３は冷却水通路、４はポンプ、６は発電用水車、７は発電機、８・９はクラッチ、１０は動力伝達装置であって、１１は案内羽根である。 (Embodiment 2)
3 and 4 show a schematic configuration of the water solar power generation system of the second embodiment. Similar to the first embodiment, 2 is a photovoltaic power generation panel, 3 is a cooling water passage, 4 is a pump, and 6 is. A water turbine for power generation, 7 is a generator, 8 and 9 are clutches, 10 is a power transmission device, and 11 is a guide blade.

図示のように、実施形態２では、発電用水車６としてクロスフロー水車を用いて、このクロスフロー水車による発電用水車６を冷却水通路３の太陽光電池パネル２の下辺部に沿って開口する冷却水出口の内部に沿って軸線方向を配置したものである。
そして、その冷却水出口内部には、発電用水車６の直前位置に、そのクロスフロー水車の羽根を押す側のみに水を当て、且つ流速を上げる案内羽根１１を設けている。
このように、冷却水出口内部に案内羽根１１を設けて、その案内羽根１１で発生するジェット水流がクロスフロー水車の羽根に当たって、発電用水車６が効率よく回転するように構成する。 As shown in the figure, in the second embodiment, a cross-flow turbine is used as the power turbine 6, and the power turbine 6 by the cross-flow turbine is cooled by opening along the lower side of the solar cell panel 2 of the cooling water passage 3. The axial direction is arranged along the inside of the water outlet.
Inside the cooling water outlet, a guide blade 11 is provided at a position immediately before the power generation turbine 6 so that water is applied only to the side pushing the blade of the cross-flow turbine and the flow velocity is increased.
In this way, the guide blades 11 are provided inside the cooling water outlet so that the jet water flow generated by the guide blades 11 hits the blades of the cross-flow turbine and the water turbine 6 for power generation rotates efficiently.

以上、クロスフロー水車による発電用水車６を冷却水通路３の太陽光電池パネル２の下辺部に沿って開口する冷却水出口の内部に沿って軸線方向を配置して、発電用水車６の直前位置に、そのクロスフロー水車の羽根を押す側のみに水を当て、且つ流速を上げる案内羽根１１を設けた構成によっても、前述した実施形態１と同様の作用効果を発揮できる。 As described above, the water turbine 6 for power generation by the cross-flow turbine is arranged in the axial direction along the inside of the cooling water outlet that opens along the lower side of the solar cell panel 2 of the cooling water passage 3, and the position immediately before the turbine 6 for power generation. A configuration in which water is applied only to the side that pushes the blades of the cross-flow turbine and the guide blades 11 for increasing the flow velocity are provided can also exert the same effects as those in the first embodiment.

（変形例）
図５は変形例を示すもので、前述した実施形態２のクロスフロー水車による発電用水車６に変えて、図示のように、前述した実施形態１と同様のペルトン水車による発電用水車６としたものである。 (Modification example)
FIG. 5 shows a modified example. Instead of the water turbine 6 for power generation by the cross-flow turbine of the second embodiment described above, the water turbine 6 for power generation by the Pelton turbine similar to the above-described first embodiment is used as shown in the figure. It is a thing.

すなわち、ペルトン水車による発電用水車６を冷却水通路３の太陽光電池パネル２の下辺部に沿って開口する冷却水出口の内部に沿って軸線方向を配置して、発電用水車６の直前位置に、そのペルトン水車のバケットを押す側のみに水を当て、且つ流速を上げる案内羽根１１を設けた構成としてもよい。 That is, the water turbine 6 for power generation by the Pelton turbine is arranged in the axial direction along the inside of the cooling water outlet that opens along the lower side of the solar cell panel 2 of the cooling water passage 3, and is located immediately before the turbine 6 for power generation. , The guide blade 11 may be provided so that water is applied only to the side pushing the bucket of the Pelton turbine and the flow velocity is increased.
