Description

Technical Field

[0001] The utility model relates to the field of dredging devices, in particular to a dredging device for urban water conservancy projects. Background Technique

[0002] In the construction of urban water conservancy projects, the laying of domestic sewage pipes is particularly important. In order to maintain the stability of domestic sewage dredging, it is necessary to regularly dredge such domestic pipes.

[0003] The existing dredging methods mostly adopt direct flushing or a combination of flushing and brushing. Among them, the combination of flushing and brushing can more efficiently achieve the dredging of water conservancy pipes. Most of these devices use a fixed frame to set up the brushing mechanism and the flushing mechanism. At the same time, a support mechanism is set on the outer wall of the fixed frame for traction or automatic walking. For the traction walking setting, multiple groups of support mechanisms will be set to surround the outer wall of the frame. Most of the existing support mechanisms are composed of moving wheels and fixed support frames, and the fixed support frames are connected by hinges. When walking in the pipe, the rotation angle needs to be set in advance. However, in the actual cleaning process of the pipe, the situation inside the pipe wall is complex, and the inner diameter of the pipe wall will be inconsistent due to the accumulation of sundries. The existing pre-adjusted support mechanism cannot meet the changing walking support, which will cause blockage during the cleaning process. Therefore, a dredging device for urban water conservancy projects is proposed. Content of the Utility Model
