[0023] A slot is provided inside the top end of the side frame 13 , and the gear 8 is engaged with the rack 14 to facilitate the displacement of the movable base plate 6 .

[0024] The bottom end of the nylon brush 11 is in contact with the top end of the photovoltaic panel 12 , so the top end of the photovoltaic panel 12 can be cleaned.

[0025] A square hole is formed inside one opposite end of the movable base plate 6 to allow the movable base plate 6 to slide on the central base plate 3 .

[0026] Working principle: When in use, first fix the photovoltaic panel 12 on the external photovoltaic bracket so that the photovoltaic panel 12 can be supported to work. When the surface of the photovoltaic panel 12 needs to be cleaned, the movable base plate 6 can be moved as a whole to the top of the photovoltaic panel 12, and then the card key 9 is slid and inserted into the card slot inside the top of the side frame 13. Subsequently, when the card key 9 is inserted into the inside of the side frame 13, the gear 8 can be engaged with the rack 14, and then the drive motor 7 is started, so that when the gear 8 rotates on the rack 14, the movable base plate 6 can be driven to move as a whole, and the bottom end of the nylon brush 11 is in contact with the top of the photovoltaic panel 12, so that The nylon brush 11 can remove the dust attached to the photovoltaic panel 12.

At the same time, by turning on the drive motor 7 to drive the gear 8 to rotate clockwise or counterclockwise, the movable base plate 6 can drive the nylon brush 11 to move back and forth on the photovoltaic panel 12, thereby removing the dust from the photovoltaic panel 12. When the movable base plate 6 needs to be installed on photovoltaic panels 12 of different sizes, the positioning bolt 4 can be screwed and rotated to loosen the positioning bolt 4 and the center base plate 3. Subsequently, the movable base plate 6 can be slid on the central base plate 3 until the card key 9 is aligned with the card slot inside the top of the side frame 13, and then the card key 9 is slid and inserted into the card slot inside the side frame 13, so that the sliding distance of the movable base plate 6 can be determined. Subsequently, the positioning bolt 4 can be screwed and rotated to the central base plate 3 to be tightened, so that the movable base plate 6 can be restricted and fixed to prevent the movable base plate 6 from sliding again on the central base plate 3. While the movable base plate 6 is sliding and adjusted, the length of the nylon brush 11 is the same as the length of the two movable base plates 6, so that the nylon brush 11 can be used to adjust the movable base plate 6 during the sliding adjustment. 11 is always located on the top of the photovoltaic panel 12, thereby preventing the local area of ​​the top of the photovoltaic panel 12 from being uncovered, so that the movable base plate 6 can be adapted to be installed on photovoltaic panels 12 of different sizes. When the device is in use, the two movable base plates 6 can be slidably connected on the central base plate 3, so that the card key 9 can be aligned with the side frame 13 on photovoltaic panels 12 of different widths. At the same time, by screwing and rotating the positioning bolt 4 and fastening it to the central base plate 3, the movable base plate 6 can be restricted and fixed to prevent the movable base plate 6 from sliding again, thereby completing the purpose of sliding regulation of the nylon brush 11 and completing the work.
