[0002] The solar photovoltaic panel cleaning device is a device used to clean the surface of solar photovoltaic panels. Its function is to keep the surface of solar photovoltaic panels clean, mainly by removing dust, sand, leaves, dirt and other impurities on the surface of photovoltaic panels through cleaning fluid and brushing, so as to maintain the light absorption capacity of the photovoltaic panel surface and improve the power generation efficiency of solar photovoltaic panels. At the same time, cleaning also helps to extend the service life of photovoltaic panels, ensuring that solar photovoltaic panels can efficiently absorb sunlight and convert it into electrical energy.

[0003] In the prior art, for example, a solar photovoltaic panel cleaning device provided by Chinese patent publication number CN219805025U uses a handle to drag a connection box to move on the surface of the photovoltaic panel, and uses an automatically rotating cleaning brush cylinder to clean the surface of the photovoltaic panel without excessive pressure. The external cleaning liquid is sprayed out through the spray hole on the spray pipe by a water pump, and there is no need to apply the cleaning liquid to the cleaning device, so cleaning is more convenient. However, the above technical solution still has the following problems:

[0004] The applicant believes that by cleaning the surface of the photovoltaic panel with a cleaning brush, dust can be removed without applying heavy pressure to the photovoltaic panel. However, when the photovoltaic panel is placed outdoors, stubborn debris is likely to remain on the surface of the photovoltaic panel due to the accumulation of impurities outdoors, while ordinary brushes can only clean the dust on the surface of the photovoltaic panel, but cannot handle the stubborn debris, resulting in unclean cleaning of the surface of the photovoltaic panel, affecting the effect of the photovoltaic panel in converting electrical energy. Utility Model Content

The brush 9 is used to clean the surface of the photovoltaic panel, and a motor 7 is fixedly installed at one end of one of the brackets 6, and the output end of the motor 7 is fixedly connected to the rotating shaft 8. By starting the motor 7, the motor 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the brush 9 to rotate, so as to realize the surface cleaning of the photovoltaic panel; a liquid storage shell 10 is arranged at the top of the bracket 6, and the liquid storage shell 10 faces the brush 9. A spray hole 11 is opened on one side, and a connecting pipe 5 is fixedly installed on the other side of the liquid storage shell 10. The connecting pipe 5 is connected to an external water pump. The external water tank is pumped out by the external water pump and sprayed toward the brush 9 from the spray hole 11, so that the surface of the photovoltaic panel can be cleaned in cooperation with the brush 9; a pulling rod 2 is rotatably connected to one side of the shell 1. By holding the pulling rod 2, the shell 1 can be driven to move along the surface of the photovoltaic panel. The brush 9 arranged in the shell 1 cleans the surface of the photovoltaic panel, which reduces the difficulty of cleaning the photovoltaic panel; a roller can be arranged on the open side of the shell 1 to reduce the friction between the shell 1 and the photovoltaic panel.

[0026] As an implementation method in this embodiment, Figure 1-Figure 4As shown, the outer part of the rotating shaft 8 is rotatably connected with an adjusting shell 13, and the two ends of the adjusting shell 13 are respectively located on both sides of the brush 9. The adjusting shell 13 is connected to the rotating shaft 8 through a bearing, and a shovel plate 14 is arranged on one side of the adjusting shell 13. The side of the adjusting shell 13 away from the shovel plate 14 is rotatably connected with a lever 3, and a hole for the lever 3 to move is provided on the shell 1; by adjusting the lever 3, the lever 3 drives the adjusting shell 13 to rotate about the axis of the rotating shaft 8, and the adjusting shell 13 drives the shovel plate 14 to rotate until it is close to the photovoltaic panel. After the brush 9 brushes the photovoltaic panel, the shovel plate 14 scrapes the debris remaining on the surface of the photovoltaic panel, so as to achieve cleaning. The adjustment of the lever 3 can drive the shovel plate 14 to press the surface of the photovoltaic panel to remove different debris.

[0027] As an implementation method in this embodiment, Figure 2-Figure 4 As shown, the adjustment shell 13 includes an integrally formed bottom shell 16 and a connecting piece 18, the connecting piece 18 is rotatably connected to the rotating shaft 8, the bearing is arranged between the rotating shaft 8 and the connecting piece 18, and the shovel plate 14 is arranged on one side of the bottom shell 16. In order to improve the close contact effect between the shovel plate 14 and the photovoltaic panel, an arc portion 17 is arranged on the bottom shell 16. When the arc portion 17 is pressurized, the bottom shell 16 gradually bends and makes the shovel plate 14 open outward, so that the shovel plate 14 and the photovoltaic panel are in contact, which is convenient for the shovel plate 14 to remove impurities on the surface of the photovoltaic panel; the middle part of the shovel plate 14 is arched, and in the initial state, the brush 9 and the shovel plate 14 are in contact with each other, and the debris on the surface of the brush 9 will fall into the material trough arranged in the bottom shell 16 along with the shovel plate 14, and a plurality of liquid holes 15 are opened in the material trough of the bottom shell 16, wherein the material trough is used to store impurities, and the liquid holes 15 are convenient for discharging water in the material trough.

[0028] As an implementation method in this embodiment, Figure 1-Figure 4 As shown, the bracket 6 is V-shaped, and a connecting frame 12 is fixedly connected between the two brackets 6. When the lever 3 drives the shovel plate 14 to rotate, the arc portion 17 contacts the connecting frame 12, causing the arc portion 17 to deform after being compressed, and the bottom end of the bottom shell 16 bends outward and drives the shovel plate 14 to contact the surface of the photovoltaic panel; in order to increase the height between the brush 9 and the photovoltaic panel, the top of the liquid storage shell 10 passes through the shell 1 through a bolt, and an adjusting cap 4 is provided. By adjusting the distance that the adjusting cap 4 is screwed into the bolt, the height of the brush 9 can be adjusted through the bracket 6, and the vertical plane part of the bracket 6 is slidably connected to the inner wall of the shell 1. When the height of the bracket 6 is adjusted by the adjusting cap 4, one side of the bracket 6 contacts the shell 1 and slides relative to the shell 1, thereby improving the stability of the bracket 6 during movement.

[0029] The working principle of the utility model is as follows: when in use, the pulling rod 2 is held by hand and the shell 1 is driven to move relative to the photovoltaic panel, the spray hole 11 sprays water on the brush 9, the lever 3 is adjusted, and the lever 3 drives the bottom shell 16 to rotate about the rotating shaft 8, the arc portion 17 contacts the connecting frame 12, causing the arc portion 17 to deform after being compressed, and the bottom end of the bottom shell 16 bends outward and drives the shovel plate 14 to contact the surface of the photovoltaic panel, so that the shovel plate 14 can remove impurities on the surface of the photovoltaic panel, thereby improving the effect of removing the surface of the photovoltaic panel. At the same time, the pressing force of the shovel plate 14 on the photovoltaic panel can be adjusted by the lever 3 to better remove debris.

[0030] When the lever 3 is released, the arc portion 17 will lean against the side wall of the connecting frame 12, and the bottom shell 16 will not move toward the photovoltaic panel. The connecting frame 12 limits the bottom shell 16 through the arc portion 17. The brush 9 contacts the shovel plate 14, and the debris on the surface of the brush 9 will fall into the material trough set in the bottom shell 16 along with the shovel plate 14. A plurality of liquid holes 15 are provided in the material trough of the bottom shell 16, wherein the material trough is used to store impurities, and the liquid holes 15 facilitate the discharge of water in the material trough.
