[0031] In some examples, a cleaning brush mounting assembly 5 is provided inside the fixing plate 406, and the cleaning brush mounting assembly 5 includes a mounting plate 501, both ends of the mounting plate 501 are provided with a slide groove 503, a spring 504 is provided in the slide groove 503, and a clamping block 502 is provided at the end of the spring 504 away from the mounting plate 501, the clamping block 502 is slidably connected to the slide groove 503, and both ends of the spring 504 are fixedly connected to the clamping block 502 and the mounting plate 501, and a cleaning brush 506 is provided on the lower surface of the mounting plate 501, and protective plates 505 are provided at both ends of the cleaning brush 506, and the protective plates 505 are fixedly connected to the mounting plate 501. The cleaning brush fixing assembly 4 and the cleaning brush mounting assembly 5 cooperate to facilitate the user to quickly replace the cleaning brush 506.

[0032] In some examples, fixing holes 101 are provided at the four corners of the first backplate 1, a second backplate 6 is provided at the end of the first backplate 1 away from the first hydraulic rod 2, and protrusions 601 are provided at the four corners of the second backplate 6.

[0033] In a specific application scenario, first, the protrusion 601 on the second back plate 6 passes through the first back plate 1, and the second bolt 602 is tightened to install the second back plate 6 on the first back plate 1, so that the device is installed on the cleaning vehicle. When in use, the first hydraulic rod 2 is extended to make the cleaning brush 506 close to the ground, and then the distance between the cleaning vehicle and the curb is observed. After the cleaning brush 506 is close to the curb by the second hydraulic rod 3, the motor 401 is turned on, and the first connecting shaft 404 is driven by the motor 401 to rotate. At this time, the first connecting shaft 404 drives the second connecting shaft 405 to rotate, so that the cleaning brush 506 rotates to clean the road surface.

After cleaning is completed, the motor 401 is turned off, and the first hydraulic rod 2 is retracted to drive one end of the second hydraulic rod 3 to be lifted, so that the cleaning brush 506 is away from the road surface. When disassembly is required, the second bolt 602 can be screwed out of the protrusion 601 and the first back plate 1 can be removed.

[0034] By adopting the above technical solution: not only can the second back plate 6 be installed on the first back plate 1 to make the device easy to disassemble, but the cleaning brush 506 can be lifted upward after cleaning by the extension and retraction of the first hydraulic rod 2 to avoid unnecessary wear and tear, and the cleaning brush fixing component 4 and the cleaning brush installation component 5 can be coordinated to facilitate the user to quickly replace the cleaning brush 506.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
