[0037] Working principle: when using the solar photovoltaic panel cleaning device, the external water pipe is connected with the water tank 2 through the water inlet 22, so that water can enter the inside of the water tank 2, the water in the inside of the water tank 2 can enter the inside of the water spraying cabin 11, the water in the inside of the water spraying cabin 11 can be sprayed out through the water spraying nozzle 15, when wiping, the two linkage rings 25 are located in the inside of the two connecting circular blocks 33, the main shaft 14 can be rotated clockwise through the clockwise rotation of the output shaft of the driving motor 6, the inner moving ring 39 can be rotated clockwise through the clockwise rotation of the main shaft 14, the top rod 43 can be rotated clockwise through the clockwise rotation of the inner moving ring 39, the top rod 43 abutting against one end of the inner side wall of the limiting ring 17 moves along the stepped structure of the inner side wall of the limiting ring 17, so that the limiting ring 17 cannot rotate with the main shaft 14, and the main shaft 14 can drive the driving gear 21 to rotate clockwise, the two driven gears 32 can be driven to rotate clockwise through the driving gear 21 and the chain 24, the two driven shafts 44 can be rotated clockwise through the clockwise rotation of the two driven gears 32, the two connecting circular blocks 33 can be rotated clockwise through the clockwise rotation of the two driven shafts 44, when the connecting circular blocks 33 rotate clockwise, the centrifugal force makes the sleeve rod extend from the inside of the first mounting groove 34, the sleeve rod drives the clamping block 37 to extend from the inside of the first mounting groove 34, in the process of rotation, the clamping block 37 is clamped to the outside of the inner groove 27, so as to drive the linkage ring 25 to rotate, the mounting pipe 31 can be rotated through the rotation of the linkage ring 25, the first rotating shaft 4 can be rotated through the rotation of the mounting pipe 31, the second roller 20 and the first roller 3 can be rotated through the rotation of the two first rotating shafts 4, the water sprayed out of the water spraying nozzle 15 reaches the surface of the solar photovoltaic panel, the surface of the solar photovoltaic panel is quickly wiped through the rotation of the first roller 3, so that the dust on the surface of the solar photovoltaic panel is removed.

[0038] When the dust on the surface of the solar photovoltaic panel is wiped, water marks will be left on the surface. By driving the output shaft of the motor 6 to rotate counterclockwise, the output shaft of the motor 6 can rotate counterclockwise, which can drive the main shaft 14 to rotate counterclockwise. By rotating the main shaft 14 counterclockwise, the top rod 43 can be driven to rotate counterclockwise. When the top rod 43 rotates counterclockwise, one end of the top rod 43 will abut against the stepped structure of the inner wall of the limiting ring 17, so that the top rod 43 rotates counterclockwise with the limiting ring 17. By rotating the second connecting plate 16 counterclockwise, the second connecting plate 16 can be driven to rotate counterclockwise, and by rotating the second connecting plate 16 counterclockwise, the two first rotating shafts 4 can be driven to rotate counterclockwise around the main shaft 14. By rotating the two first rotating shafts 4 counterclockwise, the second roller 20 and the first roller 3 can be driven to rotate counterclockwise. The two first rotating shafts 4 can also be driven to rotate counterclockwise around the main shaft 14, and the two mounting pipes 31 can be driven to rotate counterclockwise around the main shaft 14. By rotating the two mounting pipes 31 counterclockwise around the main shaft 14, the two linkage rings 25 can be driven to rotate counterclockwise around the main shaft 14. When the outer wall of the linkage ring 25 contacts the inclined surface of the trapezoidal protrusion 23 during rotation, the reaction force of the trapezoidal protrusion 23 on the linkage ring 25 causes the linkage ring 25 to move towards the first rotating shaft 4, so that the linkage ring 25 drives the two extension rods 28 to move towards the first rotating shaft 4, thereby driving the movable circular plate 26 to move towards the first rotating shaft 4, and compressing the reset spring 29 inside the mounting pipe 31, so that the reset spring 29 is deformed.

[0039] When the linkage ring 25 moves towards the first rotating shaft 4, the linkage ring 25 can be separated from the outside of the connecting circular block 33. When the two first rotating shafts 4 rotate one hundred and eighty degrees around the main shaft 14, the positions of the two linkage rings 25 correspond to the positions of the two connecting circular blocks 33 respectively, so that the positions of the first roller 3 and the second roller 20 are exchanged. The first roller 3 is located inside the heating cover 8, and the second roller 20 is located below the first roller 3. At this time, by driving the second roller 20 and the first roller 3 to rotate clockwise through the driving motor 6, the water marks on the surface of the solar photovoltaic panel can be wiped clean when the dry second roller 20 rotates and contacts the solar photovoltaic panel. The rotating first roller 3 shakes off the water marks on the surface, and the heating plate 9 inside the heating cover 8 heats the damp first roller 3, so that the first roller 3 becomes dry. Then, by repeating the above steps, the next solar photovoltaic panel can be wiped clean, so that the present application not only can wipe the dust on the surface of the solar photovoltaic panel, but also can clean the water marks on the surface of the solar photovoltaic panel.
