Description

TECHNICAL FIELD

[0001] The utility model relates to an intelligent pipeline cleaning trolley. BACKGROUND

[0002] Pipeline cleaning is an important part of urban environmental governance, and moving trolley (robot) is a common technical means for pipeline cleaning.

[0003] In the related art, the dredging mechanism of the pipeline cleaning trolley is fixed to the front end or the side end of the trolley. During the movement of the trolley, the dredging mechanism actively or passively performs dredging work according to the physical structure, which can better remove the silt on the route. However, since the silt and other substances in the pipeline may be attached to the walls of the pipeline in all directions, the conventional dredging application structure of the trolley is often fixed to one side of the trolley, which can only clean the silt and other substances in different directions by local turning or even wall climbing of the trolley, which requires high mobility of the trolley and is difficult to achieve complete cleaning.

[0004] In summary, it is urgent to find an intelligent pipeline cleaning trolley with full-direction pipeline dredging capability, simple structure, low cost and suitable for industrial application. UTILITY MODEL CONTENT
