[0002] With the continuous development of society, more and more manufacturers and enterprises usually use pipeline to carry out liquid transmission in order to be more convenient for liquid delivery, important resources such as petroleum need to be transported by oil pipeline due to the reason of mining geographical position, and in this process, deposits are often accumulated in the inner wall of the pipeline, which not only affects the quality of petroleum, reduces the conveying efficiency, but also affects the service life of the pipeline, produces safety hazards, therefore, the thorough cleaning of the deposits in the pipeline is very necessary, taking the oil pipeline as an example, there are three methods to handle the deposits in the oil pipeline at present, manual cleaning, chemical cleaning and high-pressure water jet cleaning. The manual cleaning method is simple and easy to operate, but can only be used for small volume liquid delivery pipeline, and the cleaning efficiency is low, time-consuming and laborious, and there is a certain safety hazard, which is easy to cause harm to the cleaning workers. The chemical cleaning method is to dissolve or decompose the deposits in the oil pipeline by using acid, alkali and other chemical agents, and the cleaning efficiency is high, but the concentration of the chemical agent needs to be controlled, otherwise it will cause corrosion to the inner wall of the oil pipeline. The high-pressure water jet cleaning method is to flush the deposits in the oil pipeline clean by using high-pressure jet, which can protect the oil pipeline and ensure the safety of the environment and workers, but it needs to invest high equipment cost. The above-mentioned cases refer to the cleaning method of the oil pipeline, but can also be used as the cleaning method of the liquid delivery pipeline, and the problems encountered in cleaning the liquid delivery pipeline are almost the same as those in cleaning the oil pipeline. To solve the problems encountered in cleaning the liquid delivery pipeline, a liquid delivery pipeline deposit self -walking cleaning device is proposed, in addition, the existing cleaning device is a fixed structure, which is not convenient for cleaning operation of different sizes of pipeline, therefore, it is necessary to provide a cleaning device that is convenient for cleaning operation of different sizes and enhances the universality.
