Technical Field

[0001] The utility model relates to the field of pipeline dredging, in particular to a pipeline dredging device. Background Art

[0002] During the use of pipelines, since they are rarely maintained, a large amount of impurities usually adhere to the inner wall of the pipeline after a period of time, causing blockage of the pipeline, especially for sewage pipes in residential areas. Once blocked, it causes great inconvenience to life.

[0003] At present, electric spring-type dredging devices or water pressure-type dredging devices are usually used for vertical sewage pipes in residential areas. Among them, the spring of the electric spring-type dredging device is easy to break and is difficult to clean when the power is far away from the working surface, resulting in many faults. The water pressure-type dredging device is not easy to operate and cannot cope with complex situations. If there is a serious blockage or the obstruction on the pipe wall is hard, it is difficult to effectively dredge. Utility Model Content
