Description

Technical Field

[0001] The utility model relates to the technical field of pipeline desilting, and more particularly to a petroleum pipeline desilting robot. Background Art

[0002] During use, paraffin, colloids, condensed oil, sand, and other impurities accumulate on the inner walls of oil pipelines. This can reduce the pipe diameter, reduce the conveying capacity, increase friction, increase system energy consumption, and reduce conveying quality. Therefore, regular desilting of oil pipelines is crucial. Desilting robots are often used for this purpose.

[0003] When existing dredging robots dredge the inside of oil pipelines, they generally use blades to break up the stains adhering to the inner wall of the pipeline. During the cleaning process, generally only one set of blades is used for cleaning, and the cleaning range is relatively small, resulting in low dredging efficiency for the pipeline. The position of the robot needs to be frequently adjusted for dredging, and the operation is cumbersome and inconvenient. At the same time, after the existing dredging robots break up the stains, they lack a mechanism to collect the stains. The stains deposited in the pipeline are prone to re-accumulation, resulting in incomplete dredging of the pipeline.

[0004] In view of this, we propose an oil pipeline desilting robot. Utility Model Content
