Pipe cleaner adopting revolving brush

Abstract

The invention discloses a pipe cleaner adopting a revolving brush, and the pipe cleaner is used for pipe cleaning of petroleum and natural gas pipelines. The pipe cleaner adopting the revolving brush consists of a pipe cleaner main body, a cleaning brush and a rotary mechanism, wherein a rotary shaft is mounted in the middle of the pipe cleaner main body; the cleaning brush is mounted at the front end of the pipe cleaner main body, and is connected to the front end of the rotary shaft; and the rotary mechanism is mounted at the rear end of the pipe cleaner main body, and is connected to the rear end of the rotary shaft. The end surface of a pressing wheel on the rotary mechanism and a pipeline axis have certain included angle; when the pipe cleaner moves, the pressing wheel 2 spirally moves in the pipeline, so that the rotary mechanism is driven to rotate; and the rotary mechanism drives the cleaning brush 12 to rotate through the rotary shaft 9. The cleaning brush rotates while moving forwards along with the pipe cleaner, and spirally moves in the pipeline to form a longer cleaning path, so that the pipe cleaning is more complete. Meanwhile, the cleaning brush rotates for stirring cleaned-down attachments, so that the cleaned-down attachment particles are smaller, are mixed with a fluid more sufficiently, and flow out along with the fluid easier.

Description

technical field [0001] The invention relates to the field of fluid transport pipelines, in particular to the technical field of oil and natural gas pipeline pigging, and relates to a rotating brush pig. Background technique [0002] After oil and natural gas pipelines have been in operation for a period of time, a large amount of wax, sediment, precipitates, dirt and other attachments will adhere to the inner wall of the pipeline, or rust spots will appear. These attachments will affect the conveying capacity of the pipeline, and in severe cases, they will block the pipeline and even cause accidents. Therefore, the pipeline must be regularly pigged. In addition, due to galvanic corrosion, fatigue damage, fluid erosion, defects in the pipeline itself and damage from third-party construction, coupled with the impact of natural disasters such as mountain torrents, mudslides, and earthquakes, corrosion perforation and mechanical cracks will inevitably appear in the pipeline aft...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to propose a rotating brush pig for the existing pigs with poor pigging effect and low pigging efficiency. Rotate while running to form a longer cleaning path in the pipeline, and the cleaning brush rotates to stir the cleaned attachments, making the cleaned attachments smaller and easier to discharge with the fluid in the pipeline
