[0030] Reference Figure 1-Figure 3 The present invention provides an embodiment of a high-efficiency water-based photovoltaic module cleaning device, comprising a water pump 8 for extracting and utilizing river water. A mesh plate 7 is fixedly connected to the bottom of the water pump 8, which supports the water pump 8. The mesh plate 7 is provided with a plurality of small holes inside, allowing the cleaned sewage to pass smoothly through the mesh plate 7 and accumulate at the bottom of the hull 1. The mesh plate 7 is slidably connected to the inner wall of the hull 1, increasing the mobility of the mesh plate 7 and facilitating the cleaning of bottom stains on the hull 1. A water pipe 9 is detachably connected to the top of the water pump 8, and the other end of the water pipe 9 is detachably connected to the inner wall of the nozzle 17, working together to transfer river water. The input end of the water pump 8 is fixedly connected to a suction pipe 2, and the outside of the suction pipe 2 is fixedly connected to a filter assembly for filtering the extracted river water.

[0031] The left end of the water pump 8 is closely attached to the inner wall of the hull 1. A sewage discharge pipe 13 is fixedly connected to the right end of the hull 1 for discharging the sewage accumulated inside the hull 1. A chute is provided at the bottom of the fixing plate 12. A sliding plate 11 is slidably connected to the middle of the fixing plate 12, enabling the sliding plate 11 to slide on the fixing plate 12. The top of the sliding plate 11 is fixedly connected to a water sprinkling tank 10, enabling the water sprinkling tank 10 to slide synchronously. A motor 20 is installed at the rear end of the water sprinkling tank 10, and the driving end of the motor 20 is fixedly connected to a middle bearing column 21.

[0032] The rotation of the motor 20 can drive the rotation of the middle bearing column 21. A driving gear 18 is fixedly connected to the rear end of the middle bearing column 21. The rotation of the middle bearing column 21 drives the rotation of the driving gear 18. A driven gear 19 is rotatably connected to the inner wall at the rear end of the water sprinkling tank 10. The driving gear 18 is meshed with the driven gear 19. The rotation of the driving gear 18 drives the rotation of the driven gear 19. A fixing plate 12 is fixedly connected to the rear end of the hull 1. A plurality of gear openings are provided at the front end of the top of the fixing plate 12. The plurality of gear openings are meshed with the driven gear 19. The rotation of the driven gear 19 enables the water sprinkling tank 10 to move along the fixing plate 12, driving the expansion of the lateral cleaning area of the spray head 17.

[0033] A bevel gear one 14 is fixedly connected to the rear end of the middle bearing column 21. The rotation of the middle bearing column 21 drives the rotation of the bevel gear one 14. The left end of the bevel gear one 14 is meshed with a bevel gear two 15. The rotation of the bevel gear one 14 drives the rotation of the bevel gear two 15. Rotating columns 16 are rotatably connected to the inner walls on the left and right sides of the water sprinkling tank 10. A bevel gear two 15 is fixedly connected to the outside of the rotating column 16. A spray head 17 is fixedly connected to the outside of the rotating column 16. The rotation of the bevel gear two 15 drives the rotation of the rotating column 16. The rotation of the rotating column 16 drives the rotation of the spray head 17, realizing the expansion of the longitudinal cleaning area of the spray head 17. A plurality of small holes are provided on the outside of the spray head 17, increasing the flushing area, improving the utilization rate of water, and reducing the number of repeated flushes.

[0034] Refer to Figure 2 As shown in the figure, the filtering assembly includes a filtering box 3. A box cover 4 is rotatably connected to the top of the filtering box 3, facilitating the opening and closing of the box cover 4 to take out the filter plate 6 inside the filtering box 3. A notch is provided inside the box cover 4, which together with the rotating rod 5 constitutes a structure that can lock the filter plate 6 inside the filtering box 3. The filter plate 6 is detachably connected inside the filtering box 3, facilitating the disassembly and replacement of the filter plate 6. A rotating rod 5 is threadedly connected to the top of the filter plate 6. When the rotation of the rotating rod 5 matches the notch inside the box cover 4, the box cover 4 is unlocked, and the filter plate 6 can be taken out. Otherwise, the box cover 4 is locked and fixed.

[0035] Working Principle: In daily use, starting pump 8 allows river water to enter filter box 3 through suction pipe 2. After being filtered by filter plate 6, the river water flows through water pipe 9 and then passes through nozzle 17 to clean the photovoltaic panels. This filtered river water serves as a clean water source, making it more convenient to draw water. Starting motor 20 drives driving gear 18 to rotate. Driving gear 18 meshes with driven gear 19, driving driven gear 19 to rotate. Driven gear 19 rotates in contact with the gear opening on fixed plate 12, allowing sprinkler box 10 to move back and forth on fixed plate 12, making the watering and cleaning work more efficient. The rotation of driving gear 18 drives the rotation of bevel gear 14 at its front end. Bevel gear 14 meshes with bevel gear 2 15 on the side. The rotation of bevel gear 14 drives bevel gear 2 15 to rotate. Bevel gear 2 15 and nozzle 17 are both fixed to rotating column 16. Therefore, the rotation of bevel gear 2 15 drives nozzle 17 to rotate and spray, allowing a wider area of solar photovoltaic panels to be cleaned. After cleaning, the sewage falls into the hull 1 through the photovoltaic panels or through the small holes in the mesh plate 7. When the sewage accumulates to a certain level, the sewage pipe 13 can be opened to discharge the sewage together, protecting the river water from pollution. After a period of filtration, the filter plate 6 can be removed and replaced to remove the deactivated activated carbon and larger impurities on the front filter screen.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
