[0015] The present invention provides an anhydrous cleaning device for a solar panel through improvement. Compared with the prior art, it has the following improvements and advantages: First: Through the setting of the cleaning unit in the present invention, the motor drives the driving shaft and the turntable to rotate. The rotation of the turntable drives the fixed cylinder to perform circular rotation. The rotation of the fixed cylinder drives the strip-shaped rod and the cleaning brush to move reciprocally. The reciprocal movement of the cleaning brush can clean the surface of the solar panel. Start the fan, so that the dust suction hood sucks dust through the dust suction holes and the dust suction port, and the dust enters the collection box through the hose, the fixed pipe and the fan, realizing the cleaning of the dust on the surface of the solar panel.

[0016] Second: Through the setting of the adjusting unit in the present invention, the electric telescopic rod drives the sliding block to move obliquely downward on the fixed frame. The movement of the sliding block drives the sliding column to move outward through the second connecting rod, so that the two fixed blocks on the sliding column and the two fixed blocks on the sliding tube approach each other. Furthermore, the fixed blocks drive the two arc-shaped plates to move through the first connecting rod until the two arc-shaped plates are attached to the inner wall of the rotating roller. The cleaning brush reciprocates to drive the fixed frame to reciprocate. The movement of the fixed frame drives the sliding tube, the sliding column and the arc-shaped plates to reciprocate, so that the arc-shaped plates rub against the rotating roller, thereby generating static electricity on the rotating roller. When the rotating roller rotates on the surface of the solar panel, dust and impurities on the surface of the solar panel are adsorbed.

[0017] Third: Through the setting of the extrusion unit in the present invention, the driving shaft rotates to drive the L-shaped rod to perform circular rotation, so that the L-shaped rod presses the fixed strip downward once every rotation. The movement of the fixed strip drives the L-shaped movable rod to move downward, so that the L-shaped movable rod presses the bevel block to drive the comb-shaped plate to move horizontally. The movement of the comb-shaped plate can increase the aperture of the dust suction hole, and thus can suck in fluff and sand and dust, so as not to cause blockage of the dust suction hole. The cleaning of the solar panel is realized by means of sweeping and dust suction and static electricity dust suction, and the aperture of the dust suction hole can be adjusted, improving the cleaning effect of the solar panel.

[0018] Fourth: In the present invention, the movement of the sliding block drives the L-shaped pressing rod to move downward. The movement of the L-shaped pressing rod presses the strip-shaped plate to move downward. The movement of the strip-shaped plate drives the movable column and the V-shaped scraping plate to move downward. The movement of the movable column drives the connecting spring to stretch and undergo elastic deformation, so that the V-shaped scraping plate contacts the rotating roller. The air suction port can suck away and collect the dust and impurities adsorbed by the rotating roller; at the same time, the movement of the strip-shaped plate drives the extrusion rod to move downward. The movement of the extrusion rod drives the metal elastic sheet to bend downward, so that the metal elastic sheet and the metal ring are disconnected, and thus the grounding wire is disconnected.

[0019] Fifth: In the present invention, the servo motor drives the threaded rod to rotate. The rotation of the threaded rod drives the sliding frame and the dust suction cover to move on the slide rail. The movement of the dust suction cover drives the protective cloth to be pulled out from the winding drum. The movement of the dust suction cover can clean the solar panel, and the protective cloth can cover the area that has been cleaned to prevent the swept dust from falling on the solar panel.

The movement of the fixing strip 35 drives the L-shaped movable rod 34 to move downward, so that the L-shaped movable rod 34 presses the bevel block 33 to drive the comb tooth plate 32 to move horizontally. The movement of the comb tooth plate 32 can increase the aperture of the dust suction hole 27, and then the lint and dust can be sucked in, so that the dust suction hole 27 will not be blocked.

[0026] Further, the dust suction unit includes a fan 61 fixedly connected to one end of one of the slide rails 11. A fixed pipe 6 is fixedly connected to one of the slide rails 11.

One of the sliding frames 13 is screwed onto the threaded rod 14. Through the setting of the servo motor 12, starting the servo motor 12 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 drives the sliding frame 13 and the dust suction hood 15 to move on the slide rail 11. The movement of the dust suction hood 15 drives the protective cloth 17 to be pulled out from the winding drum 16. The movement of the dust suction hood 15 can clean the solar panel.

[0033] Specific implementation steps: Start the servo motor 12 to drive the threaded rod 14 to rotate. The rotation of the threaded rod 14 drives the sliding frame 13 and the dust suction hood 15 to move on the slide rail 11. The movement of the dust suction hood 15 drives the protective cloth 17 to be pulled out from the winding cylinder 16. At the same time, start the motor 23 and the electric telescopic rod 49. The electric telescopic rod 49 drives the sliding block 410 to move obliquely downward on the fixed frame 48. The movement of the sliding block 410 drives the sliding column 42 to move outward through the second connecting rod 411. The movement of the sliding column 42 drives the compression spring 47 to be compressed and elastically deformed, so that the two fixing blocks 43 on the sliding column 42 and the two fixing blocks 43 on the sliding tube 41 approach each other. Furthermore, the fixing blocks 43 drive the two arc-shaped plates 46 to move through the first connecting rod 44 until the two arc-shaped plates 46 are attached to the inner wall of the rotating roller 4. At the same time, the movement of the sliding block 410 drives the L-shaped pressing rod 54 to move downward. The movement of the L-shaped pressing rod 54 squeezes the strip-shaped plate 53 to move downward. The movement of the strip-shaped plate 53 drives the movable column 5 and the V-shaped scraper 51 to move downward. The movement of the movable column 5 drives the connecting spring 52 to be stretched and elastically deformed, so that the V-shaped scraper 51 contacts the rotating roller 4. The movement of the strip-shaped plate 53 drives the pressing rod 55 to move downward. The movement of the pressing rod 55 drives the metal elastic sheet 57 to bend downward, so that the metal elastic sheet 57 and the metal ring 58 are disconnected, and then the grounding wire 59 is disconnected. The motor 23 drives the drive shaft 24 and the turntable 25 to rotate. The rotation of the turntable 25 drives the fixed cylinder 26 to rotate in a circle. The rotation of the fixed cylinder 26 drives the strip-shaped rod 22 and the cleaning brush 21 to move reciprocally. The reciprocal movement of the cleaning brush 21 can clean the surface of the solar panel. Start the blower 61, so that the dust suction hood 15 sucks dust through the dust suction holes 27 and the dust suction port. The dust enters the collection box 66 through the hose 63, the fixed pipe 6 and the blower 61. The reciprocal movement of the cleaning brush 21 drives the fixed frame 48 to move reciprocally. The movement of the fixed frame 48 drives the sliding tube 41, the sliding column 42 and the arc-shaped plate 46 to move reciprocally, so that the arc-shaped plate 46 rubs against the rotating roller 4, and then the rotating roller 4 generates static electricity. When the rotating roller 4 rotates on the surface of the solar panel, it can adsorb the dust and impurities on the surface of the solar panel. Under the action of the V-shaped scraper 51, the V-shaped scraper 51 can scrape the material on the rotating roller 4. When the air suction port sucks air, it can suck away and collect the dust and impurities adsorbed by the rotating roller 4. The rotation of the drive shaft 24 drives the L-shaped rod 37 to rotate in a circle, so that the L-shaped rod 37 presses the fixed strip 35 downward once every rotation. The movement of the fixed strip 35 drives the L-shaped movable rod 34 to move downward. The movement of the L-shaped movable rod 34 drives the reset spring 36 to be compressed and elastically deformed, so that the L-shaped movable rod 34 presses the hypotenuse block 33 to drive the comb-shaped plate 32 to move horizontally. The movement of the comb-shaped plate 32 can increase the aperture of the dust suction hole 27, and then can suck in the fluff and sand and dust, so as not to cause the blockage of the dust suction hole 27. It realizes the cleaning of the solar panel by means of cleaning and dust suction and electrostatic dust suction, and can adjust the aperture of the dust suction hole 27, improving the cleaning effect of the solar panel.
