Background

For petrochemical storage factories, a conveying pipeline is a carrier for connecting a storage tank and a tank car, and the storage tank and a wharf ship, and after materials are conveyed in the pipeline for a period of time, a certain scaling layer is easily formed on the inner wall of the pipeline, so that the inner diameter of the pipeline is gradually reduced, and the transmission quantity of the materials is reduced.

In order to protect the quality of materials, reduce friction resistance and prolong the service life of pipelines, the pipelines must be cleaned regularly. The traditional cleaning mode is that cleaning balls matched with the inner wall of a pipe fitting are introduced into a housekeeper to carry out line cleaning operation, and pressure fluid such as nitrogen or water is filled to drive a soft propeller to propel along a pipeline so as to clean materials. However, in the cleaning mode, the spherical surface of the cleaning ball is used for scraping the inner wall of the pipe fitting so as to achieve the purpose of cleaning, but the cleaning ball is easily resisted by the hard protruding scale block, the problem that the cleaning ball is blocked frequently occurs during cleaning, and in the case, the fluid with higher pressure is generally introduced to wash away the scale block or force the cleaning ball to extrude the scale block, but the fluid with higher pressure easily causes damage to the structure of the pipe fitting, and meanwhile, the cost is increased. Meanwhile, when the inner wall of the dirt block or the pipe fitting is locally and suddenly enlarged, the whole cleaning ball cannot well scrape dirt inside the pipe fitting, and the cleaning is not clean.

In view of the above problems that the cleaning ball is easy to be jammed and the cleaning is insufficient, some enterprises design automatic cleaning robots, and the robots automatically move in the pipe to clean the pipe, but the robots are complex in structure and high in manufacturing cost, and the environment in the pipe easily forces the whole cleaning robot to be out of order, which results in cleaning efficiency.
