Description

Technical Field

[0001] The present invention relates to the technical field of culvert dredging, and in particular to a culvert dredging device and system for urban drainage culverts. Background Art

[0002] With the acceleration of my country's urbanization process, the problem of urban sewage treatment has received more and more attention. Most of the existing sewage treatment pipelines do not separate the drainage pipes according to the source of water. Instead, a combined drainage system is adopted in which rainwater and sewage share a drainage pipe. In the existing technology, a large amount of silt and garbage will accumulate in urban drainage culverts after long-term use, causing the culverts to be blocked, affecting the normal drainage of the culverts.

[0003] When the existing dredging device is used to dredge the culvert, the garbage is easily entangled on the surface of the stirring shaft, which makes it difficult to rotate the stirring shaft and affects the dredging efficiency. In addition, if the garbage is not cleaned in time after being entangled on the surface of the stirring shaft, it will be too entangled and difficult to clean. Summary of the Invention
