The rotating shaft four 39 will drive multiple groups of knocking plates 41 to intermittently knock the filter screen 36. Since one side of the filter screen 36 is connected to the sewage filtering box 33 through a support spring 38, when the filter screen 36 is intermittently knocked, it will cooperate with the support spring 38 to produce a vibration effect, quickly discharging the impurities at the top of the filter screen 36 from the sewage discharge port 45, preventing the filter holes of the filter screen 36 from being blocked. The filtered water flows back to the water storage tank 5 through the connecting pipe 35 for storage and is ready for the next use. By setting up the sewage recycling component, the rainwater accumulated on the top of the photovoltaic panel and the wastewater generated during the flushing process can be recycled and reused, saving water resources. Among them, the rotating shaft four and the knocking plate in the sewage recycling component can automatically intermittently knock the filter screen with the inflow of sewage to make it vibrate, preventing the filter holes of the filter screen from being blocked and affecting the sewage filtering efficiency.

[0027] In summary, by means of the above technical solutions of the present invention, the water guiding clip can automatically drain and discharge the rainwater and sediments on the top of the photovoltaic panel without manual operation, saving time and effort. By setting up the water storage tank, the installation pipe, the nozzle and the reciprocating mechanism, the dust and impurities adhering to the top of the photovoltaic panel can be repeatedly flushed, so that the dust and impurities are separated from the surface of the photovoltaic panel, further improving the dust cleaning efficiency of the photovoltaic panel.
