The end of the connecting shaft 405 is engaged with a connecting sleeve 407, and the connecting sleeve 407 is rotatably connected to the slide 403. A second motor 408 is installed on the slide 403, and the output shaft of the second motor 408 is fixedly connected to the connecting sleeve 407, and the connecting shaft 405 passes through the cleaning roller brush 406.

[0025] As a technical optimization solution of the utility model, the end of the cross-section of the slide 403 is an L-shaped structure, the middle part of the cross-section of the slide 403 is a T-shaped structure, and a battery box 5 is installed on the slide 403. A battery 6 is arranged inside the battery box 5, so that the second motor 408 can be powered by the battery 6.

[0026] As a technical optimization solution of the utility model, the cross bar 8 is rotatably connected to two first rollers 9, and the cross bar 8 is rotatably connected to two second rollers 10, so that the cross bar 8 can be easily moved on the solar panel.

[0027] As a technical optimization solution of the utility model, a connecting pipe 11 is fixedly connected to the slide 403, and a plurality of nozzles 12 are installed on the connecting pipe 11, so that the solar panel can be flushed through the nozzles 12, so that it can be cleaned more thoroughly.

[0028] As a technical optimization solution of the utility model, the fixed structure 3 includes a first screw rod 302, which is rotatably connected to the fixed frame 2, and a stop block 303 is threadedly connected to the first screw rod 302. The stop block 303 is slidably connected to the fixed frame 2, and the stop block 303 abuts against the long rod 1. The end of the first screw rod 302 is fixedly connected to a rotating rod 301, and the cross-section of the stop block 303 is a T-shaped structure, so that the fixed frame 2 can be fixed, and the long rod 1 can be fixed by cooperating with the cross bar 8 through the fixed frame 2.

[0029] As a technical optimization scheme of the utility model, a locking structure 7 is provided on the slide 403, and the locking structure 7 includes a locking block 701.

A reset spring 702 is provided inside the slide 403, and one end of the reset spring 702 abuts against the locking block 701, and the other end of the reset spring 702 abuts against the slide 403. One end of the cross-section of the locking block 701 is a T-shaped structure, and the other end of the cross-section of the locking block 701 is a trapezoidal structure, so that the cleaning roller brush 406 can be quickly disassembled, thereby facilitating the replacement of the cleaning roller brush 406.

[0030] When the utility model is in use, first connect the water pipe to the connecting pipe 11. When the solar panel needs to be cleaned, the cross bar 8 can be placed on the surface of the solar panel. At this time, the two second rollers 10 will contact with the surface of the solar panel, and then the long rod 1 can be pushed. The long rod 1 drives the cross bar 8 to move. During the movement of the cross bar 8, the two second rollers 10 will roll between the surface of the solar panel, thereby reducing the resistance encountered when pushing the cross bar 8. When the cross bar 8 moves to one side of the solar panel, it will fall under the action of gravity, thereby causing the two first rollers 9 to contact with the solar panel, and at the same time, the side of the cross bar 8 will conflict with the side of the solar panel, and then the fixing frame 2 will conflict with the other side of the solar panel. When the fixing frame 2 contacts with the other side of the solar panel, the first screw rod 302 can be rotated by the rotating rod 301, and the first screw rod 302 threadedly drives the stop block 303 to move toward the long rod 1. When the stop block 303 and the long rod 1 are tightly pressed against each other, the rotating rod 301 is stopped, and the fixing frame 2 cannot slide on the long rod 1, thereby fixing the long rod 1. When the long rod 1 is fixed, the first motor 401 can be started, and the output shaft of the first motor 401 rotates to drive the second screw rod 402 to rotate, and the second screw rod 402 threadedly slides the slide 403 on the long rod 1. The movement of the slide 403 will drive the cleaning roller brush 406 to move together. At this time, the second motor 408 can be started, and the output shaft of the second motor 408 rotates to drive the connecting sleeve 407 The rotation of the connecting sleeve 407 drives the connecting shaft 405 to rotate, and the rotation of the connecting shaft 405 drives the cleaning roller brush 406 to rotate, so that the cleaning roller brush 406 can rotate during the movement. As the cleaning roller brush 406 rotates, the bristles on the cleaning roller brush 406 will clean the surface of the solar panel. At the same time, during the cleaning process, water can be sprayed through multiple nozzles 12 to flush the surface of the solar panel, so that it can be cleaned more thoroughly. By controlling the rotation of the second screw rod 402, the slide 403 can make a reciprocating motion on the long rod 1. The reciprocating motion of the slide 403 on the long rod 1 will cause the cleaning roller brush 406 to move back and forth. During the reciprocating motion, the cleaning roller brush 406 will flush the solar panel. The solar panel is automatically cleaned, thereby avoiding the need to manually move the cleaning roller 406, effectively improving the cleaning efficiency. When one area is cleaned, the position of the long rod 1 can be changed to clean another area. When all areas are cleaned, the cleaning work of the solar panel is completed. When the cleaning roller 406 needs to be replaced, the block 701 can be pulled, and the reset spring 702 will shrink. When the end of the block 701 is not engaged with the connecting ring 404, the connecting ring 404 can be removed from the slide 403. The connecting ring 404 will drive the connecting shaft 405 to move during the movement. As the connecting shaft 405 moves, the connecting shaft 405 will be separated from the connecting sleeve 407 and the cleaning roller 406 in turn.When the connecting shaft 405 and the cleaning roller brush 406 are disengaged, the cleaning roller brush 406 will fall off the slide 403, thereby realizing the rapid disassembly of the cleaning roller brush 406 and facilitating the replacement of the cleaning roller brush 406.
