They are power generation devices that can convert absorbed solar energy into electrical energy. However, since photovoltaic modules need to receive sunlight, they are usually installed in open air and relatively open environments. In actual use, they are easily covered by pollutants such as dust, which in turn affects the conversion efficiency of photovoltaic modules. Although cleaning is currently being carried out, it is basically done through manual cleaning or external dust removal equipment. The cleaning process is complicated and the cleaning efficiency is not high. Summary of the invention

[0036] It is worth mentioning that Figure 1 As shown, the photovoltaic panel 1 is tilted during cleaning, and at this time, the lower end of the photovoltaic panel 1 is just located above the water wheel 7.

[0037] Preferably, Figure 1 and Figure 5 As shown, the waterwheel 7 is provided with a plurality of baffles 71 along its rotation direction.

[0038] Preferably, Figure 1 and Figure 3 As shown, a water pump 69 is installed in the water tank 6, and the water pump 69 is rotatably connected to the screw rod 25 to drive the water pump 69 to work when the screw rod 25 rotates. The output end of the water pump 69 is connected to the water inlet channel 31 through a pipeline.

[0039] Working principle:

[0040] When the photovoltaic panel 1 needs to be cleaned, the motor 24 is started to drive the screw rod 25 to move, and then the water pump 69 starts to work, and the water in the water tank 6 is transmitted to the water inlet channel 31 of the water outlet roller 3 through the pipeline, and sprayed to the surface of the photovoltaic panel 1 through the water outlet. While the water pump 69 is working, the moving column 22 moves along the axial direction of the screw rod 25, and drives the first connecting rod 51 and the second connecting rod 52 to move along the photovoltaic panel 1. In this process, due to the force of the tension spring 9, the friction roller 81 is close to the photovoltaic panel 1, so when the second connecting rod 52 moves, the friction roller 81 and the driving pulley 82 rotate, and the driving pulley 82 drives the driven pulley 83 to rotate through the belt 84, thereby driving the brush roller 4 to rotate to clean the photovoltaic panel 1. The surface is scrubbed to keep the photovoltaic panel 1 clean, and the wastewater flowing along the photovoltaic panel 1 enters the waterwheel 7, which is driven by the force of water potential to start rotating the waterwheel 7, thereby driving the convex column 72 to rotate eccentrically and slide in the long groove 641, so that the third connecting rod 64 swings and drives the fourth connecting rod 65 to move. Under the action of the guide plate 67 and the spring 68, the fourth connecting rod 65 drives the filter plate 62 to move in the sliding cavity 66, thereby shaking the filtered impurities to both sides of the filter plate 62 to avoid clogging of the filter plate 62, thereby realizing the cleaning of the photovoltaic panel 1 and the filtering treatment of the wastewater after cleaning, thereby improving the recycling of water resources; and the setting of the drain port 61 is that when it is opened, the water in the water tank 6 can be discharged to replace it with new clean water.
