[0030] The terraced agricultural-photovoltaic complementary photovoltaic panel cleaning system of the embodiment of the utility model is implemented by placing a water tank 21 on a terrace located on the upper layer of the bracket 1, raising the water tank 21 to a certain height, and spraying water along the water slope to clean the photovoltaic panel 11. The height potential energy of the water can be used to increase the pressure of the water in the cleaning pipe 22 to achieve the effect of quickly cleaning the photovoltaic panel 11, and the operation is convenient.

[0031] The terraced agricultural-photovoltaic complementary photovoltaic panel cleaning system of the embodiment of the utility model can quickly clean the dust on the photovoltaic panel 11, improve the cleaning efficiency, and ensure the power generation efficiency of the photovoltaic panel 11.

[0032] In some embodiments, Figure 2 As shown, the cleaning assembly 2 includes a nozzle 25, which corresponds one-to-one to the cleaning holes on the cleaning pipe 22 and is sealed to the cleaning holes.

[0033] By providing the nozzle 25 , the spray water pressure at the cleaning hole position is increased, and the spray area of ​​the water body is increased to increase the cleaning area of ​​the photovoltaic panel 11 that can be covered by a single cleaning hole, thereby ensuring the cleaning effect of the photovoltaic panel 11 .

[0034] In some embodiments, Figure 3 As shown, the cleaning component 2 includes a drainage pipe 24, which is arranged corresponding to the water tank 21 and is arranged in the water tank 21. A transfer box 3 is arranged between the water tank 21 and the cleaning pipe 22. The transfer box 3 is connected to the drainage pipe 24. The transfer box 3 is used to temporarily store water to form a water bridge between the drainage pipe 24 and the cleaning pipe 22.

[0035] A transfer box 3 is provided, and the transfer box 3 can temporarily store the water in the water storage tank 21, so that the water level in the transfer box 3 is higher than the height of the position where the cleaning pipe 22 is connected to the transfer box 3 and the height of the position where the drainage pipe 24 is connected to the transfer box 3, so as to form a water bridge between the drainage pipe 24 and the cleaning pipe 22, and the drainage pipe 24, the transfer box 3 and the cleaning pipe 22 together form a siphon structure; when the water level in the water storage tank 21 is higher than the height of the position where the drainage pipe 24 is connected to the transfer box 3, the first switch valve 23 is opened, and the cleaning pipe 22 can operate normally. When the cleaning operation is completed, the first switch valve 23 is closed, and the water level in the water storage tank 21 is When the height is lower than the position where the drainage pipe 24 is connected to the transfer box 3, since the first switch valve 23 is closed, under the action of atmospheric pressure, there is still water in the drainage pipe 24, and the water bridge between the drainage pipe 24 and the cleaning pipe 22 still exists. When the first switch valve 23 is opened again at this water level, the cleaning pipe 22 discharges the water in the transfer box 3 and generates negative pressure in the transfer box 3. Under the action of atmospheric pressure, the water in the water storage tank 21 continues to be sucked into the transfer box 3, and the water pressure in the cleaning pipe 22 is increased. Through the siphon principle, the dust on the photovoltaic panel 11 is quickly cleaned, thereby improving the cleaning efficiency.

[0036] In some embodiments, Figure 3 As shown, the drainage pipe 24 is L-shaped, one end of the drainage pipe 24 is connected to the side wall of the water storage tank 21 and communicated with the transfer box 3, and the other end of the drainage pipe 24 extends into the water body in the water storage tank 21.

[0037] By setting the drainage pipe 24 to be L-shaped, the distance between the end of the drainage pipe 24 and the bottom wall of the water tank 21 can be reduced. When the water level in the water tank 21 is constant, the volume of water in the water tank 21 that can be used through the drainage pipe 24 is increased.

[0038] In some embodiments, Figure 3 As shown, the height of the position where the cleaning pipe 22 is connected to the transfer box 3 is not higher than the height of the position where the drainage pipe 24 is connected to the transfer box 3.

[0039] The height at which the cleaning pipe 22 is connected to the transfer box 3 is not higher than the height at which the drainage pipe 24 is connected to the transfer box 3 , forming a level liquid height difference, which facilitates the cleaning pipe 22 to discharge the water in the transfer box 3 .

[0040] In some embodiments, Figure 3 As shown, a regulating pipe 4 is provided on the transfer box 3, and the height of the position where the regulating pipe 4 is connected to the transfer box 3 is higher than the height of the position where the cleaning pipe 22 is connected to the transfer box 3, the other end of the regulating pipe 4 is connected to the cleaning pipe 22, and the position where the regulating pipe 4 is connected to the cleaning pipe 22 is located on the side of the first switch valve 23 on the cleaning pipe 22 away from the transfer box 3, and a second switch valve 41 is provided on the regulating pipe 4.

[0041] The transfer box 3 is provided with a regulating pipe 4. When the water is replenished in the transfer box 3, the second switch valve 41 can be opened to ensure that the air pressure in the transfer box 3 is consistent with the atmospheric pressure. When the water reaches the height of the position where the regulating pipe 4 is connected to the transfer box 3, the water level in the transfer box 3 is determined, and the second switch valve 41 is closed to ensure that when the water level in the water storage tank 21 is lower than the height of the position where the drainage pipe 24 is connected to the transfer box 3, when the cleaning pipe 22 performs a spraying operation to clean the solar panels, a negative pressure can be generated in the transfer box 3, and the normal cleaning operation of the cleaning pipe 22 is ensured through the siphon effect.

[0042] In some embodiments, Figure 3 As shown, the height of the position where the regulating tube 4 is connected to the transfer box 3 is higher than the height of the position where the drainage tube 24 is connected to the transfer box 3.

[0043] The height of the position where the regulating pipe 4 is connected to the transfer box 3 is higher than the height of the position where the drainage pipe 24 is connected to the transfer box 3. When the water in the transfer box 3 is replenished, it is convenient to ensure that the water level in the transfer box 3 is higher than the height of the position where the drainage pipe 24 is connected to the transfer box 3, and to ensure that when the water level in the water storage tank 21 is lower than the height of the position where the drainage pipe 24 is connected to the transfer box 3, the normal cleaning operation of the cleaning pipe 22 is ensured.

[0044] In some embodiments, Figure 1 As shown, a water collection trough 12 for collecting rainwater is provided on the bracket 1. The water collection trough 12 is connected to the water storage tank 21 on the corresponding platform through a guide pipe 13.

[0045] By providing the water collecting tank 12, rainwater on the photovoltaic panel 11 can be collected, reducing the use of water resources when cleaning the photovoltaic panel 11, which is more in line with green and environmentally friendly production requirements.

[0046] In some embodiments, a filter is provided on the guide tube 13, and the filter is used to absorb and filter dust in rainwater.

[0047] By providing a filter, impurities in the rainwater are prevented from clogging the cleaning holes, etc., thereby ensuring that the cleaning pipe 22 performs normal cleaning operations on the photovoltaic panel 11 .
