[0023] Specifically, in this structure, the staff will directly remove the cleaning sponge 7 or waterproof cloth that needs to be replaced from the surface of the first Velcro 6 and the second Velcro 29 to avoid damage to one cleaning surface and the need to replace the entire cleaning surface.

[0024] In a specific embodiment, as shown in the attached Figure 2As shown, two fixed blocks 9 are fixedly connected to the bottom of the main frame 1, a rotating shaft 10 is rotatably connected between the two fixed blocks 9, a T-shaped connecting block 11 is fixedly connected to the surface of the rotating shaft 10, and the rotating shaft 10 is bolted to the fixed blocks 9 to facilitate angle adjustment.

[0025] Specifically, in this structure, the staff first loosens the bolts, then rotates the T-shaped connecting block 11 to a suitable angle according to the angle of the photovoltaic module, and then tightens the bolts.

[0026] In a specific embodiment, as shown in the attached Figure 4 As shown, an adjustment structure is provided at the bottom of the T-shaped connecting block 11, and the adjustment includes a telescopic tube 12 fixedly connected to the bottom of the rotating shaft 10, a hand-held tube 13 is slidably connected to the outside of the telescopic tube 12, a threaded extrusion tube 14 is fixedly connected to one end of the hand-held tube 13, a sleeve 15 is slidably connected to the surface of the telescopic tube 12, a non-slip hose 16 is installed on the surface of the sleeve 15, the sleeve 15 is threadedly connected to the threaded extrusion tube 14, an L-shaped square rod 17 is fixedly connected to the surface of the sleeve 15, a T-shaped circular groove 18 is provided on the surface of the hand-held tube 13, a plurality of sliders 19 are slidably connected to the inside of the T-shaped circular groove 18, and an L-shaped square rod 20 is fixedly connected to one side of the plurality of sliders 19, a slide groove 21 is provided on the outer wall of the L-shaped square rod 20, and the slide groove 21 is slidably connected to the L-shaped square rod 17 to facilitate the adjustment of the tool length.

[0027] Specifically, in this structure, the worker rotates the sleeve 15, and after the sleeve 15 is detached from the threaded extrusion tube 14, the worker pulls out or retracts the telescopic tube 12 according to factors such as the length of his own arm, and then rotates the sleeve 15 in the opposite direction to connect with the threaded extrusion tube 14 to fix the telescopic tube 12.

[0028] In a specific embodiment, as shown in the attached Figure 2 As shown, two circular holes 22 are provided on both sides of the main frame 1, and two cylindrical holes 23 are provided on both sides of the movable frame 3, and the two circular holes 22 and the two cylindrical holes 23 are symmetrical to each other, a first spring 24 is fixedly connected inside the cylindrical hole 23, a sliding circular plate 25 is fixedly connected at one end of the first spring 24, the sliding circular plate 25 is slidably connected to the cylindrical hole 23, a cylinder 26 is fixedly connected to the top of the sliding circular plate 25, and a ball 27 is installed on the top of the cylinder 26 to facilitate the connection between the movable frame 3 and the main frame 1.

[0029] Specifically, in this structure, the staff presses the ball 27 away from the first partition 2, and then pulls the movable frame 3. The ball 27 at the other end of the movable frame 3 slides inside the main frame 1. After the ball 27 moves to the position of the circular hole 22, it is subjected to the elastic force of the first spring 24 and the sliding circular plate 25 and the cylinder 26 and pops out from the cylindrical hole 23, thereby fixing the movable frame 3 to the main frame 1.

[0031] Working principle of the present invention: When cleaning large-area photovoltaic modules, the staff first adjusts the structure according to their own height, arm length, etc. The staff first lifts the tool, then rotates the sleeve 15 of the main frame 1 downward, and the anti-skid hose 16 prevents the staff from slipping. After the sleeve 15 is separated from the threaded extrusion tube 14, it is restricted by the L-shaped square rod 17 to prevent the sleeve 15 from slipping when the tool length is extended. The staff pulls out or pulls back the telescopic tube 12 according to the tool length they need, and then rotates the sleeve 15 in the opposite direction to fix the telescopic tube 12. At the same time, when facing photovoltaic modules at different angles, the T-shaped connecting block 11 on the rotating shaft 10 can be rotated, and then bolted to adapt to the angle of the photovoltaic module, and the cleaning agent is sprayed on the photovoltaic module. Then, the second Velcro 29 on one side of the main frame 1 is fixed. The cleaning sponge 7 is attached to the photovoltaic component, and the photovoltaic component is cleaned by pushing the hand-held tube 13 up and down, and then the hand-held tube 13 is rotated to attach the absorbent cloth 8 on the second Velcro 29 on the other side of the main frame 1 to the photovoltaic component for scraping and cleaning. When the area of ​​the photovoltaic component is large, the ball 27 on the top of the main frame 1 is pressed to pull the moving frame 3 out of the main frame 1, and the second spring 28 inside the moving frame 3 applies elastic force to the T-shaped sliding plate 5 to push the T-shaped sliding plate 5 out. At the same time, due to the limiting effect of the moving frame 3, the T-shaped sliding plate 5 and the moving frame 3 maintain the same horizontal plane, and the first Velcro 6 on the surface of the T-shaped sliding plate 5 is also adhered with the cleaning sponge 7 and the absorbent cloth 8, and the cleaning sponge 7 and the absorbent cloth 8 are located on the same plane as the cleaning sponge 7 and the absorbent cloth 8 on the surface of the main frame 1, thereby increasing the cleaning area.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
