Technical Field

The utility model relates to the technical field of pipelines, in particular to a cleaning mechanism for in-situ repair of the inner wall of a trenchless pipeline.

Background Art

A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high pressure part of the pipeline to the low pressure part. It can also be conveyed by the fluid's own pressure or gravity12. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. During the long-term use of pipelines, impurities such as silt and dirt will adhere to the inner wall of the pipeline. If the inner wall of the pipeline is cleaned, cleaning the pipeline can avoid large flow surface losses to a certain extent, thereby improving the water flow capacity.
