Desilting device for emergency treatment of damage of sewage pipeline

Abstract

The invention discloses a desilting device for emergency treatment of damage of a sewage pipeline. The desilting device comprises a box body, a left-right through channel cavity is formed in the box body, and a power annular cavity is formed in the box body. According to the desilting device, sludge on the inner wall of the sewage pipeline can be removed through self-feeding in the sewage pipeline, smoothness of the sewage pipeline is facilitated, and meanwhile, the better dredging effect can be provided in a reciprocating rotating dredging manner; in addition, according to the device, a damage point of the sewage pipeline is judged according to the difference of water flow pressure in front of and behind the damage point of the sewage pipeline, and the sewage pipeline is directionally guided in front of the damage point, so that sewage can smoothly flow through a channel of the device without flowing through the damaged position of the pipeline, continuous leakage of the sewage is effectively avoided, and an emergency temporary response scheme is provided for pipeline damage; and meanwhile, a positioning device can be carried through the device, the damaged position of the sewagepipeline is effectively positioned, and a worker can repair the damaged pipeline in time.

Description

technical field [0001] The invention relates to the field of dredging of sewage pipelines, in particular to a dredging device for emergency treatment of damaged sewage pipelines. Background technique [0002] Sewage pipes are an essential part of the municipal system. Its function is to collect people's domestic sewage, and usually transport the sewage to sewage treatment plants to meet discharge standards before being discharged into water bodies or recycled. [0003] During the long-term use of the sewage pipeline, the inner wall of the pipeline will inevitably absorb a lot of silt. The long-term accumulation of silt will reduce the actual working area of ​​the pipeline, cause pipeline blockage, and reduce the efficiency of sewage transportation. The existing dredging method is often manual cleaning of the pipeline. Suction and dredging inside is inefficient and extremely time-consuming and labor-intensive. In addition, if the pipeline is damaged and leaked, because most o...

AI Technical Summary

Problems solved by technology

[0005] The accumulation of silt in sewage pipes for a long time will reduce the actual working area of ​​the pipes, and the existing desilting methods are inefficient. If there is damage and leakage inside the pipes, it will not be easy to detect in a short time, resulting in a large amount of sewage leakage and polluting the environment.
