[0020] When in use, the device can be transferred using the universal wheels 6. After the cleaning component of the device is moved to fit the wall, starting the cleaning component can automatically clean the wall. Starting the driving mechanism can drive the lifting bracket 3 to move up and down on the surface of the supporting component. The lifting bracket 3 drives the cleaning component to move up and down in fit with the wall, so that the wall can be automatically and efficiently cleaned. Starting the spraying component can spray the water in the water tank 4 onto the wall that needs to be cleaned, which is beneficial for the cleaning component to scrub the wall.

[0021] The supporting assembly includes multiple groups of fixing blocks 7 welded on the side of the fixing bracket 2, and a fixing rod 8 passing through the lifting bracket 3 is installed between the two corresponding groups of fixing blocks 7. The lifting bracket 3 can slide up and down on the surface of the fixing rod 8, which can provide a stable moving track for the lifting bracket 3.

[0022] Among them, two groups of cleaning components are symmetrically installed on the lifting bracket 3, which is beneficial to expand the cleaning area and improve efficiency. Specifically, the cleaning component includes a servo motor 9 fixedly installed on the lifting bracket 3, and a first cleaning disc 10 is installed at the end of the output shaft of the servo motor 9. The side of the lifting bracket 3 is rotatably installed with a first rotating rod 12 connected to the second cleaning disc 11. The first rotating rod 12 and the output shaft of the servo motor 9 are connected by a transmission component.

In this structure, since a flexible water baffle is provided, the sewage splashing outward on the left and right sides will be blocked by the flexible water baffle to prevent the sewage from splashing outward. At the same time, since the servo motor located on the left rotates counterclockwise and the servo motor located on the right rotates clockwise, the servo motors in the same group of cleaning components rotate in the same direction as the first rotating rod. In this way, when the two groups of cleaning components are working, the sewage located at the upper end will splash toward the sewage trough, and most of the sewage will be discharged downward from the sewage trough. Therefore, the discharge direction of the sewage generated by the cleaning disc can be better controlled to prevent the sewage from splashing everywhere.

At the same time, the first cleaning disc can block part of the sewage thrown out by the second cleaning disc, so that the sewage can be better controlled to splash outward.

[0025] Start the servo motor 9, which drives the first cleaning disc 10 to rotate. The servo motor 9 also drives the driving wheel 13 to rotate. The driving wheel 13 drives the driven wheel 14 and the first rotating rod 12 to rotate. The first rotating rod 12 drives the second cleaning disc 11 to rotate.
