[0002] Pipeline cleaning refers to the cleaning of the pipeline to restore the surface of the material inside the pipeline. After cleaning, a dense chemical passivation film is formed on the clean metal surface, which can effectively prevent the re-generation of dirt and effectively protect the equipment from corrosion or other chemical damage, effectively ensuring the safety of the equipment and extending the service life of the equipment.

[0003] For example, the patent number is CN111632967A, a pipeline cleaning robot, the invention can freely and quickly adjust the gap between the two arc-shaped stainless steel cleaning scrapers according to the diameter of the inner wall of the pipeline, so as to meet the needs of rapid cleaning of the dirt on the inner wall of the pipeline.
