AI Technical Summary

Technical Problem

Coalbed methane transmission pipelines are prone to blockage due to coal dust and debris after long-term use, and existing technologies are difficult to use effectively to clean them.

Method used

A pipeline cleaning device for coalbed methane was designed, which uses components such as multi-stage telescopic rods, gear motors, and cleaning brushes. The cleaning brushes are brought into contact with the inner wall of the pipeline by manual or electric means, and the transmission connection structure and movable installation structure are used to ensure that the cleaning brushes are always in contact with the inner wall, combined with rotation cleaning.

Benefits of technology

It enables efficient cleaning of coalbed methane transmission pipelines, avoids pipeline blockage, and extends service life.
