Furthermore, in the case of rainy weather, it was difficult to secure sufficient fresh water due to the amount of electricity generated.

This system automatically controls the amount of water produced by the seawater desalination equipment to achieve the intended purpose.
〔発明の実施例〕
以下図示した実施例に基づいて本発明の詳細な説明する
。[Embodiments of the Invention] The present invention will be described in detail below based on the illustrated embodiments.
図において１は太陽電池モジュールであり、１０は海水
淡水化装置である。In the figure, 1 is a solar cell module, and 10 is a seawater desalination device.
太陽電池モジュール１は太陽電池架台２上に取付けられ
電気的には電圧、電流の関係から適当に直並列接続され
、そして図示はしていないが海水淡水化装置］０に電力
を供給している。太陽電池架台２は太陽との対向関係、
すなわち太陽電池出力増大のため緯度と同程度の傾斜を
有するように形成されている。The solar cell module 1 is mounted on a solar cell mount 2, electrically connected in series and parallel as appropriate due to voltage and current relationships, and supplies power to a seawater desalination device (not shown). . The solar cell mount 2 faces the sun,
That is, in order to increase the output of the solar cell, it is formed to have an inclination comparable to the latitude.
太陽電池の受光面周辺、すなわち太陽電池架台２の傾斜
下方部には雨樋３が設けられ、雨樋の端部は導水管５を
介して貯水槽４に結合されている。A rain gutter 3 is provided around the light-receiving surface of the solar cell, that is, at the lower inclined portion of the solar cell mount 2, and an end of the rain gutter is connected to a water tank 4 via a water conduit 5.
導水管５の途中に設けられている６は雨量計で、この雨
量計の電気信号は増巾器７を介して造水量指令装置８の
指令値に合わされる。A rain gauge 6 is provided in the middle of the water pipe 5, and an electric signal from this rain gauge is adjusted to a command value of a water production amount command device 8 via an amplifier 7.
この合わされた信号は造水量制御器９に与えられるよう
になっている。尚雨樋３、導通管５、貯水槽４にて集水
装置が形成され、１１は造水量の制御装置を示す。This combined signal is given to the water production amount controller 9. A water collection device is formed by the rain gutter 3, the conductive pipe 5, and the water storage tank 4, and 11 indicates a control device for the amount of water produced.
このような構成で、雨天時に太陽電池モジュール１の面
に降った雨水は、傾斜面下方に移動し傾斜面下方に取け
られた雨樋３に集められる。雨樋３の端部には導水管５
が取付けられているから、雨樋３により集められた雨水
はこの導水管５を通り貯水槽４に貯えられる。With such a configuration, rainwater that falls on the surface of the solar cell module 1 during rainy weather moves below the slope and is collected in the rain gutter 3 provided below the slope. A water pipe 5 is installed at the end of the rain gutter 3.
is installed, rainwater collected by the rain gutter 3 passes through the water pipe 5 and is stored in the water tank 4.
このようにして太陽電池表面に降水した雨水は貯水槽４
に貯えられるが、この場合導水路５の途中に雨量計６が

より補正を受け、造水量制御器９への信号が変化し海水
淡水装置の淡水造水量が制御される。以上により降雨量
によって海水淡水装置の造水量が制御される。The rainwater that has fallen on the surface of the solar cells in this way is collected in a water storage tank 4.
In this case, a rain gauge 6 is installed in the middle of the headrace waterway 5, and an electric signal proportional to the amount of rain is extracted by this rain gauge. This electrical signal is amplified to an appropriate magnitude through an amplifier 7 and added to the command value of the water production amount commanding device 8 according to the relationship shown in the figure, that is, the amount of water produced is subtracted. As a result, the water production amount command value is corrected by the rainfall signal from the amplifier 7', the signal to the water production amount controller 9 changes, and the fresh water production amount of the seawater freshwater apparatus is controlled. As described above, the amount of fresh water produced by the seawater freshwater device is controlled depending on the amount of rainfall.
このようにこの構成であると、雨天時太陽電池出力が低
下した場合においても淡水を確保することが可能であり
、さらに降雨量によって海水淡水化装置の造水量を制御
することができるので淡水化のための消費電力の低下を
計ることができ蓄電池の容量を低減することができる。With this configuration, it is possible to secure fresh water even when the solar battery output decreases during rainy days, and furthermore, the amount of water produced by the seawater desalination equipment can be controlled depending on the amount of rainfall, so the desalination It is possible to measure the reduction in power consumption and reduce the capacity of the storage battery.

雨水を利用することにより約１５％前後淡水が多く得ら
れることがわかる。Now let's calculate the amount of rain that falls on the solar cell surface when this solar cell module is used to configure a power source with a maximum output of 25 kW. If the solar cell installation angle is 30' and the area of the solar cell where rain falls is A, then the power is 0W. Considering a land with an annual rainfall of 1800 mn, the average amount of rain falling on the solar cell surface per day is 1,8 m x 217 rrf X -= 1,
1 rrr/day for 365 days, and an average of 1.1 r&/day of fresh water can be obtained from the solar cell surface. By the way, the amount of solar radiation is 3400Kca.
Q/A solar cell with a maximum output of 25kW and 100
In the case of an electrodialysis seawater desalination system equipped with a 0Ah-110V storage battery, the average daily amount of fresh water produced is estimated to be 7 to 8 po/day. It can be seen from this that by using rainwater that falls on the solar cell surface, approximately 15% more fresh water can be obtained.
また雨水により得られた淡水量だけ海水淡水装置
置の造水量を減少するとすれば約１５％の電力量の節約
となる。Furthermore, if the amount of fresh water generated by the seawater freshwater device is reduced by the amount of fresh water obtained from rainwater, the amount of electricity will be saved by about 15%.

及び海水・淡水の水路系は省略しである。In the top view, the power system for solar cells, storage batteries, and seawater desalination equipment, and the seawater/freshwater waterway system are omitted.

蓄電池の容量を低減することができる。As explained above, the present invention provides a water collection device around the light-receiving surface of a solar cell, and also provides a seawater desalination device with a control device that operates according to the amount of water in the water collection device. Since the amount of water produced by the seawater desalination equipment is automatically controlled, it is possible to secure a sufficient amount of fresh water even when the solar battery output decreases during rainy days. Since it can be controlled, the power consumption for desalination can be reduced, and the capacity of storage batteries can be reduced.
