Embodiment

[0015] As Figure 1 and Figure 2A device for cleaning depressions, comprising a main beam 1, a planetary conveyor belt frame 2 is installed on the main beam 1, a support gasket height adjustment bolt 3 is installed on the planetary conveyor belt frame 2, there are two support gasket height adjustment bolts 3, the support gasket height adjustment bolt 3 is connected to an adjustment bolt fixing plate 4, a support gasket 5 is arranged above the adjustment bolt fixing plate 4, the support gasket 5 is connected to the top of a long brush hanging beam 6, a pulley 7 is placed on the support gasket 5, the pulley 7 is fixed to both sides of the rear of the bottom of a special-shaped structure water tank 8 and can roll along the upper surface of the support gasket 5, the middle of the bottom of the special-shaped structure water tank 8 is rotationally connected to a support plate 10 through a connecting plate 9, one end of a small tension spring 11 is connected to the middle of the support plate 10, the front end is connected to one end of a water tank cushion block assembly 12, the other end of the water tank cushion block assembly 12 is connected to the bottom of the special-shaped structure water tank 8, a front corner 13 is arranged below the front side of the special-shaped structure water tank 8, and a rear corner 14 is arranged above the rear side, the water tank cushion block assembly 12 is slidably connected to the support plate 10, the water tank cushion block assembly 12 can slide up and down in the support plate 10, there are two groups of the connecting plate 9, the support plate 10, the water tank cushion block assembly 12 and the small tension spring 11, and they are symmetrically installed about the middle line of the special-shaped structure water tank 8, the other end of the small tension spring 11 is connected to a small tension spring fixing bolt 15, the small tension spring fixing bolt 15 is connected to a small tension spring fixing plate 16, the small tension spring fixing plate 16 is fixed to the main beam 1, the middle of the long brush hanging beam 6 is movably connected to an electric lifting double tension spring assembly 18 through a connecting block 17, the bottom is connected to a long brush 19, the electric lifting double tension spring assembly 18 is fixed to the main beam 1 through an electric lifting double tension spring assembly frame 20, the long brush 19 is connected to a driving device, the driving device includes a transmission motor 21, the transmission motor 21 is connected to a driving pulley 22 through a transmission main shaft 26, the driving pulley 22 is connected to a driven pulley 24 through a belt 23, the driven pulley 24 is installed at both ends of the long brush 19, a brush cover 25 is covered above the long brush 19, and the transmission motor 21 is fixed to the main beam 1.

[0016] The process flow and working principle of the present invention are as follows: When the garbage sweeper is in a stationary state (the ground contact distance of the long sweeping brush 19 has been adjusted to a reasonable height by the electric lifting double spring assembly 18 pushing the long sweeping brush suspension beam 6), the front corner 13 of the special-shaped water tank 8 is full of water, and the rear corner 14 is empty. The special-shaped water tank 8 is supported by the support plate 10. When the drive motor 21 operates, it drives the driving pulley 22 to rotate through the drive main shaft 26, and the driving pulley 22 drives the driven pulley 24 and the long sweeping brush 19 to work through the belt 23. When the garbage sweeper travels to a steep or sloping area, the water at the front corner 13 flows to the rear corner 14, causing the rear corner 14 to move downward under gravity. The pulley 7 moves downward along the support gasket 5, pressing down the long sweeping brush 19 to maintain the cleaning effect. Moreover, the long sweeping brush 19 can move left and right. When cleaning in a concave area, after the low-lying area has the weight of water flow, the long sweeping brush 19 automatically tilts towards the road depression, achieving the expected cleaning effect.
