[0013] The beneficial effects of this utility model are:

[0014] This invention restricts the movement of the photovoltaic panel and controls the cleaning components on the dust removal mechanism to move along the surface of the photovoltaic panel, thereby achieving the purpose of cleaning the photovoltaic panel. This avoids the situation in the prior art where the dust removal roller and the conveyor belt come into contact when the photovoltaic panel moves to contact the dust removal roller, effectively improving the feasibility of the photovoltaic panel cleaning work and providing a guarantee for the normal operation of the photovoltaic panel cleaning work.

[0015] In this invention, an electric telescopic rod is installed between the U-shaped connecting plate and the workbench, and the electric telescopic rod is electrically connected to a distance sensor. This allows the device to detect the distance between the cleaning component and the photovoltaic panel, and control the electric telescopic rod to adjust the height of the U-shaped connecting plate in a timely manner. This ensures that the cleaning component can maintain contact with photovoltaic panels of different specifications, thereby enabling the device to meet the cleaning needs of photovoltaic panels of different specifications and further improving the practicality of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5A dust removal device for photovoltaic panels used in photovoltaic power generation includes a workbench 1, a conveying mechanism 2 on the workbench 1, a photovoltaic panel 3 placed on the conveying mechanism 2, a dust removal mechanism 4 on the workbench 1, and a U-shaped connecting plate 41 on the workbench 1. The U-shaped connecting plate 41 is inserted into the workbench 1, and its opening is located above the workbench 1. A servo motor 42 is connected to the outside of the U-shaped connecting plate 41. A threaded rod 43 is connected to the output shaft of the servo motor 42. The two ends of the threaded rod 43 are rotatably connected to the opening of the U-shaped connecting plate 41. A moving plate 44 is threadedly connected to the threaded rod 43, and a cleaning component 45 is connected to the bottom of the moving plate 44.

[0026] When in use, the device transports the photovoltaic panel 3 to the coverage area of ​​the dust removal mechanism 4 via the conveying mechanism 2. During dust removal, the conveying mechanism 2 is paused, and the servo motor 42 rotates, driving the threaded rod 43 to rotate synchronously. This drives the moving plate 44, which is threaded onto it, to move synchronously. The moving plate 44 then moves the cleaning component 45 from one side of the photovoltaic panel 3 to the other side. During the movement, the cleaning component 45 contacts the surface of the photovoltaic panel 3, thereby achieving the purpose of cleaning the photovoltaic panel 3. After cleaning is completed, the servo motor 42 rotates in the opposite direction, thereby controlling the moving plate 44 to drive the cleaning component 45 back to the initial position for the next round of cleaning.

[0027] Specifically, in this embodiment, a limiting rod 46 is provided on the U-shaped connecting plate 41, and the moving plate 44 is slidably connected to the limiting rod 46, so that the moving plate 44 can be slidably connected to the limiting rod 46, thereby controlling the moving direction of the moving plate 44 through the limiting rod 46, thereby ensuring that the moving plate 44 always moves in a direction perpendicular to the photovoltaic panel 3.

[0028] Specifically, in this embodiment, a protective cover plate 47 is provided on the U-shaped connecting plate 41. The protective cover plate 47 is located above the threaded rod 43, so that the protective cover plate 47 can cover the threaded rod 43, thereby preventing workers from accidentally touching and getting injured when the threaded rod 43 rotates, and preventing foreign objects from contacting the threaded rod 43 and affecting the normal operation of the device.

[0029] Specifically, in this embodiment, the cleaning component 45 includes a device plate 451 connected to the bottom of the movable plate 44. A scraper 452 and a cleaning sponge 453 are movably connected to the bottom of the device plate 451, so that when the cleaning component 45 cleans the photovoltaic panel 3, the scraper 452 first performs preliminary cleaning of the dust on the surface of the photovoltaic panel 3, and then the cleaning sponge 453 cleans it again, thereby improving the cleaning quality of the photovoltaic panel 3. Furthermore, the connection method in which the scraper 452 and the cleaning sponge 453 are movably connected to the device plate 451 facilitates the replacement and maintenance of the scraper 452 and the cleaning sponge 453.

[0030] Specifically, in this embodiment, a dust suction component 5 is provided on the side of the workbench 1 away from the cleaning component 45, and a dust collection box 6 is detachably connected to the bottom of the workbench 1. The outlet of the dust suction component 5 is connected to the dust collection box 6 through a negative pressure fan, so that the dust cleaned by the cleaning component 45 to the other side of the photovoltaic panel 3 can be sucked up by the dust suction component 5 and transported into the dust collection box 6, thereby achieving the purpose of uniformly cleaning the dust and avoiding the situation of dust overflowing and causing dust to be raised.

[0031] Specifically, in this embodiment, an electric telescopic rod 7 is provided at the bottom of the workbench 1. The moving end of the electric telescopic rod 7 is connected to the U-shaped connecting plate 41. A distance sensor 8 and a control module 9 are provided on the workbench 1. The distance sensor 8 and the electric telescopic rod 7 are both electrically connected to the control module 9. The distance sensor 8 detects the distance between the bottom of the cleaning component 45 and the top of the photovoltaic panel 3. When the distance value between the two does not match the set value, the control module 9 sends a command to the electric telescopic rod 7. The distance of the U-shaped connecting plate 41 is adjusted by the operation of the electric telescopic rod 7, so that the cleaning component 45 can contact the surface of the photovoltaic panel 3 of different thicknesses, thereby meeting the cleaning needs of photovoltaic panels 3 of different specifications and further improving the practicality of the device.

[0032] Specifically, in this embodiment, a vision camera 10 is provided on the protective cover plate 47. The vision camera 10 and the conveying mechanism 2 are both electrically connected to the control module 9. The vision camera 10 can monitor the position of the photovoltaic panel 3 on the workbench 1. When it is detected that the photovoltaic panel 3 conveying mechanism 2 conveys the photovoltaic panel 3 to the coverage area of ​​the dust removal mechanism 4, a signal is sent to the control module 9 to control the operation of the conveying mechanism 2, so that the operation of the conveying mechanism 2 can be adapted to the cleaning requirements of the photovoltaic panel 3, thereby improving the cleaning speed.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
