[0016] Example: Please see Figures 1-13 This utility model provides a technical solution: a high-efficiency cleaning mechanism for photovoltaic panel components, including a photovoltaic support frame 1, a water storage tank 4 and a cleaning pump 5. A photovoltaic panel 2 is arranged on the inner side of the photovoltaic support frame 1, a horizontal moving mechanism is arranged above the photovoltaic support frame 1, and a cleaning mechanism 6 is arranged on the horizontal moving mechanism. The cleaning mechanism 6 includes a horizontal plate 11, a rotating conveyor belt 22, and a drive motor 18. The drive motor 18 is fixed to the upper end of the horizontal plate 11. A drive wheel 21 and a driven wheel 20 are arranged below the horizontal plate 11. The output end of the drive motor 18 passes through the horizontal plate 11 and is fixedly connected to the upper end of the drive wheel 21. The upper end of the driven wheel 20 is rotatably connected to the upper end of the horizontal plate 11. The drive wheel 21 and the driven wheel 20 are connected by transmission through the rotating conveyor belt 22. Several cleaning mechanisms 19 are arranged on the outer wall of the rotating conveyor belt 22. Cleaning pipes 13 are arranged on both the left and right sides of the horizontal plate 11. The cleaning mechanism 19 is located between two cleaning pipes 13. A cleaning mechanism 19 is arranged on the upper part of the horizontal plate 11. There is a connecting pipe 17, and several water spray holes 15 are opened on the lower side wall of the cleaning pipe 13. The two cleaning pipes 13 are connected through the connecting pipe 17. The input end of the cleaning pump 5 is connected to the water storage tank 4, and the output end of the cleaning pump 5 is connected to the connecting pipe 17. When cleaning the surface of the photovoltaic panel 2, the water in the water storage tank 4 is introduced into the cleaning pipe 13 through the connecting pipe 17 by the cleaning pump 5, and sprayed onto the surface of the photovoltaic panel 2 through the water spray holes 15 on the side wall of the cleaning pipe 13. At the same time, the moving motor 7 in the transverse moving mechanism drives the moving screw 10 to rotate, thereby driving the moving block 8, the cleaning mechanism 6 and the sweeping mechanism 19 to move to the right to perform the cleaning operation of the photovoltaic panel 2. The cleaning mechanism 19 includes a drive gear 24, a fixed plate 23, a cleaning plate 27, and a sliding rod 26. The fixed plate 23 is fixed on the outer wall of the rotating conveyor belt 22. The lower end of the drive gear 24 is fixedly connected to a rotating cylinder 25. The lower end of the rotating cylinder 25 passes through the fixed plate 23 and extends below the fixed plate 23.

The upper end of the abutment spring 29 is fixedly connected to the upper inner wall of the rotating cylinder 25. The lower end of the cleaning brush 28 contacts the upper surface of the photovoltaic panel 2. Under the action of the abutment spring 29, the cleaning brush 28 can always abut against the upper surface of the photovoltaic panel 2, so as to avoid the photovoltaic panel 2 being unable to be effectively cleaned due to the wear of the cleaning brush 28. A rotating track 12 is fixedly connected to the lower end of the horizontal plate 11. The outer sides of the rotating track 12 are fixedly connected to the adjacent side walls of the two cleaning pipes 13 on the left and right sides respectively. Several drive grooves 16 are opened on the inner side wall of the rotating track 12. The drive gear 24 meshes with the drive grooves 16. While the drive motor 18 drives the rotating conveyor belt 22 and the cleaning mechanism 19 to rotate, the drive gear 24 and the drive grooves 16 can drive the rotating cylinder 25, the sliding rod 26, the cleaning plate 27 and the cleaning brush 28 to rotate. Compared with the traditional unidirectional cleaning roller, the cleaning brush 28 of this device rotates synchronously during the revolution, which can clean the stains on the surface of the photovoltaic panel 2 from multiple angles and greatly improve the cleaning efficiency of the photovoltaic panel 2. Two cleaning pipes 13 are fixedly connected to rubber scrapers 14 at their far ends. The lower end of the rubber scraper 14 abuts against the upper end of the photovoltaic panel 2. When cleaning the photovoltaic panel 2, the rubber scraper 14 on the front side of the moving direction cleans the debris accumulated on the surface of the photovoltaic panel 2, and the rubber scraper 14 on the rear side of the moving direction can scrape off the water film remaining on the surface of the photovoltaic panel 2 after cleaning to prevent secondary dust accumulation. The lateral movement mechanism includes two auxiliary plates 3, two moving blocks 8, two limiting slide rods 9, and a moving screw 10. The two auxiliary plates 3 are fixed to the left and right ends of the upper surface of the photovoltaic support frame 1, respectively. The left ends of the two limiting slide rods 9 are fixedly connected to the right side wall of the left auxiliary plate 3. The right ends of the two limiting slide rods 9 pass through the two moving blocks 8 and are fixedly connected to the left side wall of the right auxiliary plate 3, respectively. The lower end of the moving block 8 abuts against the upper end of the photovoltaic support frame 1. A moving motor 7 is fixedly connected to the left end of the left auxiliary plate 3. The output end of the moving motor 7 passes through the left auxiliary plate 3 and is fixedly connected to the left end of the moving screw 10. The right end of the moving screw 10 passes through the rear moving block 8 and is rotatably connected to the left end of the right auxiliary plate 3. The moving screw 10 is threadedly connected to the rear moving block 8. The upper ends of the two moving blocks 8 are fixedly connected to the lower end of the horizontal plate 11. The lateral movement mechanism enables the cleaning mechanism 6 to move in the left and right directions.

[0017] Working principle: During use, the cleaning pump 5 introduces water from the water storage tank 4 into the cleaning pipe 13 through the connecting pipe 17, and sprays it onto the surface of the photovoltaic panel 2 through the spray holes 15 on the side wall of the cleaning pipe 13. At the same time, the moving motor 7 in the transverse moving mechanism drives the moving screw 10 to rotate, which in turn drives the moving block 8, the cleaning mechanism 6, and the sweeping mechanism 19 to move to the right. During the movement, the rubber scraper 14 on the right side performs preliminary cleaning of the debris on the surface of the photovoltaic panel 2. At the same time, the drive motor 18 drives the drive wheel 21 to rotate, which in turn drives the driven wheel 20 to rotate the rotating conveyor belt 22. As the rotating conveyor belt 22 rotates, several sweeping mechanisms 19 move along the rotating conveyor belt 22. The conveyor belt 22 rotates and moves to clean the surface of the photovoltaic panel 2. Simultaneously, several cleaning mechanisms 19 rotate, driving gears 24 and drive grooves 16 to rotate, which in turn drives the rotating cylinder 25, sliding rod 26, cleaning plate 27, and cleaning brush 28 to rotate. Compared to traditional unidirectional cleaning rollers, the cleaning brush 28 of this device rotates synchronously during its revolution, enabling multi-angle cleaning of dirt on the surface of the photovoltaic panel 2, greatly improving the cleaning efficiency. After the cleaning mechanism 19 completes the cleaning of the photovoltaic panel 2 surface, the left-side rubber scraper 14 removes any remaining water film on the surface, preventing secondary dust accumulation. After cleaning is complete, the drive motor 18 and cleaning pump 5 are turned off, and the cleaning mechanism 6 is moved to its initial position using a lateral movement mechanism.
