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 installation of large-scale mega solar requires a large area, installation on the water is increasing.
And in the float type solar power generation device installed on the water, the one that cools the solar power generation panel by putting the heat dissipation plate connected to the heat absorption plate on the back of the solar power generation panel into the water from the float is patented It is proposed in Document 2.
Further, Patent Document 3 proposes cooling the photovoltaic power generation panel by causing the water under the float to be sucked and ejected from the hole in the center of the float to flow down to the photovoltaic power generation panel on the float. Yes.

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。 DESCRIPTION OF EMBODIMENTS 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 solar power generation system to which the present invention is applied. 1 is a stand, 2 is a solar power generation panel, 3 is a cooling water passage, 4 is a pump, 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, a photovoltaic power generation panel 2 is installed obliquely on a water base 1 such as a pond, a lake, or the sea. Although not shown, the gantry 1 has a foot that reaches the bottom of the water.
This photovoltaic power generation panel 2 has a large area in which a large number of solar cell modules are integrated in the vertical and horizontal directions, and its light receiving surface is installed obliquely toward the sun, and the entire back surface of the light receiving surface. A cooling water passage 3 surrounded by the housing is formed along the line.
In this cooling water passage 3, a heat sink (not shown) that also serves as a strength securing rib along the vertical direction connected to a heat sink (not shown) attached to the back surface of the photovoltaic power generation panel 2 is spaced laterally. 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。 Under the gantry 1, a pump 4 is installed in water, and a heat insulating water storage tank 5 is provided at a cooling water inlet provided in an upper part of the photovoltaic power generation panel 2.
In this water storage tank 5, water is pumped and stored, that is, water for cooling the photovoltaic power generation panel 2 is stored. The water in the water storage tank 5 is pumped by cold water that is not exposed to direct sunlight 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 battery panel 2 in the cooling water passage 3. As shown in FIG. 2, the power generation water turbine 6 is arranged in the axial direction along the cooling water outlet that opens along the lower side of the solar battery panel 2 of the cooling water passage 3.
In addition, 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 power generation turbine 6 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 power generation water turbine 6, and a clutch 8 is provided between the power generation water turbine 6 and the power 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 (right end in FIG. 2) of the shaft portion of the power generation water turbine 6 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 power generation water turbine 6.

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 set to 10 m or more.
Accordingly, a water head difference of 10 m or more is generated 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。 During operation of the above-described water solar power generation system, when the temperature of the solar power generation panel 2 rises and reaches a predetermined value, water is stored in the cooling water passage 3 attached to the entire rear surface of the solar power generation panel 2. By allowing the water in the tank 5 to flow down, the entire back surface of the photovoltaic power generation panel 2 is cooled.
Here, the driving of the initial pump 4 is performed using the electric power generated by the photovoltaic power generation panel 2. That is, when the solar power generation panel 2 needs to be cooled, since the solar power generation panel 2 is in a power generation state, the pump 4 is driven using the surplus power as indicated by a 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 power generation water turbine 6 rotates by flowing down the cooling water passage 3 on the entire rear surface of the photovoltaic power generation panel 2 from the water storage tank 5 pumped by the pump 4, the clutch 9 is brought into a connected state, and the power generation water turbine 6 The pump 4 is driven through the clutch 9 and the power transmission device 10 by the rotation.
That is, the kinetic energy of the water flowing down the cooling water passage 3 on the entire rear surface of the photovoltaic power generation panel 2 is absorbed by the power generation water turbine 6, and the rotational force of the power generation water turbine 6 is used as the power of the pump 4. Pumping 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。 In addition, when energy is slightly short, the pump 4 is driven with the surplus electric power of the photovoltaic power generation panel 2, and water is pumped.
In this way, surplus power of the photovoltaic power generation panel 2 can be stored as potential energy of water, and can be passed through the cooling water passage 3 to generate power with the lower power generation turbine 6. As a result, the amount of power generation can be smoothed 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 floating solar power generation system of the embodiment, the cooling water flows from the water storage tank 5 installed at the upper entrance to the cooling water passage 3 provided on the entire rear surface of the solar power generation panel 2. The solar panel 2 can have sufficient cooling performance.
Therefore, the power generation efficiency by the solar power generation panel 2 on the water can be increased.

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。   And the water turbine 6 for electric power generation arrange | positioned at the exit of the cooling water channel | path 3 is rotated with the water after photovoltaic cell panel 2 cooling, and it produces electric power with the generator 7 through the clutch 8 of a connection state, and uses for electric power sale. Can do.

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 generation turbine 6, and the power generation turbine 6 by the cross flow turbine is opened along the lower side of the solar battery panel 2 in the cooling water passage 3. The axial direction is arranged along the inside of the water outlet.
Inside the cooling water outlet, a guide vane 11 is provided at a position immediately before the power generation water turbine 6 so as to apply water only to the side where the blade of the crossflow turbine is pushed and to increase the flow velocity.
In this way, the guide vane 11 is provided inside the cooling water outlet, and the jet water flow generated by the guide vane 11 hits the vane of the cross-flow turbine so that the power generation water turbine 6 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 axial direction is arranged along the inside of the cooling water outlet that opens the water turbine 6 for power generation by the crossflow water turbine along the lower side portion of the solar battery panel 2 of the cooling water passage 3, and the position immediately before the water turbine 6 for power generation. In addition, the same effect as that of the first embodiment can also be exhibited by a configuration in which water is applied only to the side where the blades of the crossflow turbine are pressed and the guide blades 11 are provided to increase the flow velocity.
