After multiple cleanings, the brushes on the cleaning roller 2 can be replaced to ensure that the cleaning is clean; the two moving blocks 1 are respectively located on both sides of the solar photovoltaic panel 3; the two moving blocks 1 are hollow inside and have no obstruction at the bottom, and are provided with a roller 4 extending from the bottom; the cleaning roller 2 extends into the inside of the moving block 1, and the roller 4 is fixed on the cleaning roller 2; a cleaning air pipe 5 is also provided between the two moving blocks 1; the cleaning air pipe 5 is located at the lower side of the cleaning roller 2; one end of the cleaning roller 2 is connected to an air pump 6; the air pump 6 is fixed on one of the moving blocks 1; a plurality of evenly distributed air nozzles 7 are provided on the cleaning air pipe 5; the air nozzle 7 The direction of the jet is toward the obliquely downward direction of the cleaning air pipe 5 moving downward, which is used to jet the surface of the solar photovoltaic panel 3 for cleaning; the solar photovoltaic panel 3 is provided with a slide groove 8 on both sides; the rollers 4 are respectively located in the slide grooves 8 on both sides; the slide groove 8 is provided with a limit baffle 9 at both ends; a sensor 10 is provided at the limit baffle 9 in the slide groove 8, which is used to sense the movement of the roller 4 into position; a drive motor 11 is provided on the side of one of the moving blocks 1; the rotating end of the drive motor 11 passes through the moving block 1 and is welded to the cleaning roller 2 inside, which is used to drive the cleaning roller 2 to rotate; the cleaning device also includes a control terminal 12; the control terminal 12 is arranged on one of the moving blocks 1; the air pump 6, the sensor 10 and the drive motor 11 are all connected to the control terminal 12; the control terminal 12 is provided with a start button 13; the control terminal 12 is provided with a program for controlling the rotation of the drive motor 11 and the jet of the air pump 6.

[0027] The working principle of the present invention is:

[0028] When it is necessary to clean the surface of the solar photovoltaic panel 3, press the start button 13. At this time, the control terminal 12 will control the driving motor 11 to rotate and the air pump 6 to spray. The driving motor 11 drives the cleaning roller 2 to rotate, and drives the roller 4 to rotate at the same time. The roller 4 moves from top to bottom in the slide 8. In this process, the air nozzle 7 continuously sprays gas to wash the surface of the solar photovoltaic panel 3. At the same time, the cleaning roller 2 at the rear continuously adheres to the surface of the solar photovoltaic panel 3 to clean the dust and stains on the surface. When the roller 4 moves to the end, it will be blocked and stopped by the limit baffle 9. At the same time, the sensor 10 senses that the roller 4 moves into place and sends a signal to the control terminal 12. The control terminal 12 sends a control signal to the driving motor 11. After receiving the signal, the driving motor 11 reverses and drives the cleaning device to return to the top of the solar photovoltaic panel 3 along the original path, and is blocked and stopped by the limit baffle 9 at the top. At this time, turn off the start button 13, the cleaning device stops running, and the cleaning is completed. If it is considered that the cleaning is not clean, the cleaning device can be started again for cleaning.
