Pipeline robot and pipe cleaning method thereof

Abstract

The invention discloses a pipeline robot and a pipeline cleaning method thereof. The pipeline robot comprises a front pipeline cleaning main body and a rear pipeline cleaning main body, the front cleaning pipe main body comprises a jet device, a scraping device and a driving device which are mounted on the front cleaning pipe main body; the post-cleaning pipe main body comprises a solution storage device; the front pigging pipe body and the rear pigging pipe body are both made of polyurethane foam materials and are installed with a to-be-cleaned pipeline in an interference fit mode. According to the pipeline robot, the high-pressure jet device is additionally arranged in the front cleaning pipe body, 360-degree dead-angle-free high-pressure jet can be achieved in the advancing process of the pipeline robot, and a good dirt removal effect can be achieved in cooperation with various cleaning auxiliaries; a main body of the pipeline robot is made of polyurethane foam, most dirt in the pipeline can be squeezed and scraped off by means of the characteristics of light weight, good sealing performance, good compressibility, good flexibility and the like of the polyurethane foam, solid impurities on the wall of the pipeline are further removed by means of a hard brush and a leather cup, and the cleaning effect is outstanding.

Description

technical field [0001] The invention relates to the field of intelligent pigging, in particular to a pipeline robot and a pigging method thereof. Background technique [0002] At present, oil and gas pipelines play an increasingly important role in daily life. With the increase of pipelines, the growth of pipeline age and the increase of transportation pressure, oil and gas pipelines will have pipeline scaling and impurities adhesion after long-term operation, which will cause a series of pipeline failure problems. These pipeline failures can greatly affect their transportation efficiency and even cause blockage and corrosion of the pipeline. According to statistics, the accident rate of pipelines caused by corrosion and blockage is as high as 38.2%, and the loss caused by the decline of transportation efficiency caused by pipeline leakage and corrosion and scaling cannot be ignored. It can be seen that regular and effective cleaning of pipelines is a thorny problem that e...

Problems solved by technology

[0003] At present, the biggest problem in pipeline cleaning is that the pigging effect is not obvious in certain environments, especially for pipelines with large drop or relatively large terrain fluctuations, this problem is more serious

At the same time, for pigging quality control, the current standards are relatively simple, and the pigging standards formulated by various countries are more or less human-influenced, and it is difficult to achieve a unified evaluation
