According to the cleaning status, if the rotary brush device of the present invention is to be properly attached to the guardrail or wall to be cleaned, then the translation device is responsible for it, specifically: pull the second brush inward Three handles 62, through the third oil pipe 66, the oil inlet of the oil inlet and outlet interface 70 is fed into the oil, and the moving oil cylinder 53 is just displaced to the left. At this time, the tripod 39 also slides synchronously to the left along the guide rod 4, and because the whole adjusting device is hingedly connected with the tripod 39, therefore, when the tripod 39 moves to the left, the tripod 39 carries the moving device -displacement towards the left, also because the whole rotary brush device is hingedly connected with the adjusting device, therefore, the rotary brush device is also displaced synchronously to the left. Conversely, if the third handle 62 is pushed outwards, then the reverse movement to the right occurs, until the bristles 17 of the rotary brush device contact the surface of the object to be cleaned. At the same time, the water flow introduced from the water inlet pipe 5 is sprayed onto the bristles 17 of the hairbrush 18 by the nozzle 23. Since the fourth handle 63 is turned inward at this time, a pair of fourth oil pipes 67 form a drive oil pump motor 9 to work. The hydraulic oil circuit of the hydraulic oil circuit makes the central shaft 22 rotate under the work of the oil pump motor 9, and the brush 17 scrubs the guardrail or the wall surface. During the whole scrubbing process, the cleaning vehicle 58 is in the slowly advancing state.

When the height of the rotary brush device is to be adjusted, for example, when the rotary brush device is in a high position, the first handle 60 is pulled inward, and the right end port of the oil inlet and outlet port 68 is connected through the first oil pipe 64 (as shown in FIG. 1 ). position), the lifting cylinder 27 will move to the right, push the connecting rod 28, make the connecting rod 28 upturned, and drive the brush holder 7 to move up; on the contrary, when the first handle 60 is pushed outward, the oil inlet and outlet ports will The left end interface of 68 enters oil, and lifting oil cylinder 27 just displaces to the left, and connecting rod 28 is dropped. The positions and states of the rotary brush device shown by the upturning and downward movement of the connecting rod 28 are respectively disclosed by Fig. 4 and Fig. 5 . Therefore, the rotary brushing device of the present invention can be adapted to brushing guardrails and parapet walls of different heights, especially tunnel walls.

When the inclination of the rotary brush device is to be adjusted, the second handle 61 is pulled inward by the driver or the sanitation worker, and the left end interface of the oil inlet and outlet interface 69 (shown in FIG. Show the position as an example) into the oil, the inclined oil cylinder 15 just shifts to the left and rotates an angle, because the brush holder 7 of the rotary brush device is hinged with the inclined oil cylinder 15, so the upper end of the brush holder 7 is driven to deviate slightly to the left, An oblique angle is produced between the brush 18 and the guardrail or parapet wall or tunnel wall to be cleaned, and vice versa. This adjustment can make the brush 18 suitable for cleaning the special-shaped surface, especially as mentioned above, the cross-sectional shape of the highway guardrail is usually wavy or 3-shaped, so adjusting the rotary brush device can show a good cleaning effect.
