[0024] The working principle of the present invention is as follows: when in use, the cleaning mechanism is started, and the moving direction and moving path are controlled by the sanitation electric vehicle body 1, so that the road on the path can be cleaned. When the cleaning force needs to be adjusted, the adjusting threaded rod 5 is rotated by the knob, and the adjusting threaded rod 5 rotates, and it will be threadedly engaged with the threaded through hole 4, and then relatively move with the threaded through hole 4, so that under the guidance of the two No. 1 guide rods 7, the bearing plate 6 and the multiple cleaning brushes 18 are driven to move, and the cleaning force is controlled by controlling the distance between the multiple cleaning brushes 18 and the ground. The closer the cleaning brushes 18 are to the ground, the greater the cleaning force; After completing the above, the cleaning range can be adjusted according to actual needs. The cleaning brushes in the two cleaning components can be individually controlled by their corresponding control components. Here, a control component and a cleaning component are taken as an example. When adjustment is needed, the two-way threaded rod 9 is rotated by turning the handle. The two-way threaded rod 9 rotates, and the two nuts 10 are restricted by the guide plate 12 and the second guide rod 11. The two nuts 10 will be threadedly engaged with the two-way threaded rod 9, so that the two nuts 10 move toward each other, approach each other or move away from each other, and then the two cleaning brushes 18 are driven to move toward each other through the No. 1 fixing plate 13 and the No. 2 fixing plate 14. The cleaning range of the sanitation electric vehicle body 1 is adjusted by adjusting the distance between the two cleaning brushes 18. Through the cooperation of multiple cleaning brushes 18, the road surface to be cleaned can be covered to the greatest extent, which is beneficial to improving the cleaning effect and cleaning efficiency. After completing the above, start The two motors 15 are driven to operate the cleaning assembly. Taking a cleaning assembly as an example, the motor 15 drives the No. 1 rotating shaft 16 to rotate, thereby driving the No. 1 bevel gear 19 to rotate, and the No. 2 bevel gear 22 and the slide bar 21 are driven to rotate through the meshing transmission. The slide bar 21 rotates, and under the restriction of the two limit sliders 24 and the limit slide groove 23, the sleeve 20 is driven to rotate, and then the No. 3 bevel gear 25 is driven to rotate, and the No. 4 bevel gear 26 and the No. 2 rotating shaft 17 are driven to rotate through the meshing transmission. The No. 1 rotating shaft 16 and the No. 2 rotating shaft 17 rotate, and the respective cleaning brushes 18 are driven to rotate to realize the cleaning function. When the distance between the two cleaning brushes 18 changes, the slide bar 21 drives the two limit sliders 24 to slide in the limit slide groove 23. The rotation of the slide bar 21 will still drive the sleeve 20 to rotate, and the transmission state will not change, which is more in line with actual usage scenarios and usage requirements.
