[0033] In this embodiment: a water pump 4 is installed to draw water from the water tank 3 into the connecting water pipe 9. The S-shaped connecting water pipe 9, which is laid over a large area, allows the water to continuously cool the bottom of the photovoltaic panel body 6 as it flows through the pipe. A connecting pipe 7 is installed to distribute the water flow to various outlet pipes 10. Finally, the water is sprayed out through the nozzle 12 to spray the surface of the photovoltaic panel body 6. A corrugated pipe 11 is installed to provide some flexibility, which makes it easy to adjust the tilt angle of the nozzle 12. The nozzle 12 can not only wash the dust off the photovoltaic panel surface, but also achieve the purpose of cooling. A water collection tank 2 is installed so that the sprayed water will flow down the tilted photovoltaic panel body 6 into the water collection tank 2. After being filtered by the drain pipe 17 and the water re-enters the water tank 3, it will be continuously guided by the water pump 4 to the connecting water pipe 9, achieving the effect of recycling and continuous cooling.

[0034] The filter fitting 5 includes a filter tube 13 and a filter cotton 14. The filter cotton 14 is sleeved inside the filter fitting 5, and a filter screen 15 is provided above the filter cotton 14. The bottom of the filter tube 13 extends into the water tank 3.

[0035] In this embodiment, by setting filter cotton 14 and filter screen 15 inside the filter tube 13, some small impurities can be isolated to avoid the problem of impurities clogging the water pipe, and the circulating water flow can be cleaner and the cleaning can be more thorough.

[0036] An isolation net 16 is fitted on the top of the water collection tank 2, and a drain pipe 17 is installed through the bottom of the water collection tank 2. The drain pipe 17 is threadedly connected to the filter pipe 13.

[0037] In this embodiment: by setting up an isolation net 16, some larger impurities such as leaves can be isolated from the water collection tank 2. The drain pipe 17 is threadedly connected to the filter pipe 13. The drain pipe 17 is made of flexible material, which can separate the drain pipe 17 from the filter pipe 13 to facilitate the maintenance of the filter pipe 5.

[0038] The bottom of the photovoltaic panel body 6 contacts the top of the connecting water pipe 9. Both sides of the connecting water pipe 9 are fixedly connected to the inner wall of the photovoltaic panel bracket 1. The other end of the connecting water pipe 9 passes through the photovoltaic panel bracket 1 and is fixedly connected to the water pump 4.

[0039] In this embodiment: by setting the bottom of the photovoltaic panel body 6 to contact the top of the connecting water pipe 9, the bottom of the photovoltaic panel body 6 can receive the low temperature generated by the water flow inside the connecting water pipe 9, so as to achieve the purpose of cooling the photovoltaic panel body 6. By fixing both sides of the connecting water pipe 9 to the inner wall of the photovoltaic panel bracket 1, the connecting water pipe 9 can have a certain degree of support.

[0040] The other end of the water tank 3 is provided with a water inlet, and a plug is provided inside the water inlet. The bottom of the water tank 3 is provided with a partition, and the partition is fixedly connected to the photovoltaic panel bracket 1.

[0043] In this embodiment, mounting plates and bolts are provided to facilitate the installation and disassembly of the photovoltaic panel body 6 and the photovoltaic panel bracket 1.

[0044] The implementation principle of a cooling device for photovoltaic panels according to this application is as follows: When it is necessary to cool the photovoltaic panel body 6, the water pump 4 first guides the water in the water tank 3 to the S-shaped connecting water pipe 9 laid over a large area. During the flow of water in the connecting water pipe 9, the bottom of the photovoltaic panel body 6 can be continuously cooled. At the same time, the connecting water pipe 9 guides the water flow to the connecting pipe 7 again, and the water flow from the connecting pipe 7 is divided to each water outlet pipe 10. Finally, the water is sprayed out by the nozzle 12 to spray the surface of the photovoltaic panel body 6, which can not only wash away the dust on the surface of the photovoltaic panel body 6, but also achieve the purpose of cooling. After spraying Water flows continuously down the inclined photovoltaic panel body 6 into the water collection tank 2. The isolation net 16 at the top of the water collection tank 2 can intercept larger impurities such as leaves washed off the surface of the photovoltaic panel body 6. The intercepted wastewater will then enter the filter pipe 5 through the drain pipe 17. In the filter pipe 5, some small impurities will be separated again by the filter screen 15 and filter cotton 14 to avoid the problem of impurities clogging the water pipe. This also makes the water flow that circulates to wash the photovoltaic panel body 6 cleaner and more thorough. The water that re-enters the water tank 3 will be continuously guided by the water pump 4 to the connecting water pipe 9 to achieve the effect of recycling and continuous heat dissipation.
