The main function of pipelines is to transport liquid, gas or mixture from one place to another, so as to meet the transportation needs of different substances. In industrial production, pipelines can be widely used in heating and cooling systems, air conditioning systems and other equipment.

[0003] When manufacturing companies perform regular maintenance on production equipment, they often need to inspect and maintain the pipes connecting the various devices. Since some pipes are in contact with acidic and corrosive compounds for a long time, dirt and sediment are easily generated on the inner wall of the pipe. Therefore, cleaning the dirt on the inner wall of the pipe becomes an indispensable part of the pipe maintenance operation. At present, when cleaning the inner wall of the pipe, the operator needs to enter or lie on one side of the pipe as a whole and clean the inner wall with a brush. The above-mentioned prior art requires operators to exert a lot of labor in the pipeline maintenance operation, the operation time is long and the efficiency is low. At the same time, the notch along the pipe edge of the pipe is easy to scratch the operator, resulting in potential safety hazards. Utility Model Content
