High-speed rotating brush pipe cleaner

Abstract

A high-speed rotating brush pipe cleaner is used for cleaning petroleum and natural gas pipelines. The high-speed rotating brush pipe cleaner is composed of a pipe cleaner supporting body, a cleaning brush, a rotating mechanism and a planetary gear transmission, wherein the rotating mechanism is installed at the rear end of the pipe cleaner supporting body; the cleaning brush is installed at the front end of the pipe cleaner supporting body; the planetary gear transmission is installed in the pipe cleaner supporting body; the rotating mechanism, a rotating shaft, the planetary gear transmission and the cleaning brush are sequentially connected. When the pipe cleaner runs, the rotating mechanism is driven to rotate, the cleaning brush is driven to rotate at a high speed after rotation of the rotating mechanism is transmitted to the planetary gear transmission through the rotating shaft, and therefore the cleaning brush can form a longer cleaning path in a pipeline; meanwhile, the cleaning brush rotates at a high speed so that attachments which are cleared away can be stirred, attachment particles which are cleared away are finer and fully mixed with fluid, and the attachment particles which are cleared away can be discharged along with the fluid more easily.

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 high-speed rotary 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 pip...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to propose a high-speed rotating brush pig for the existing pigs with poor pigging effect and low pigging efficiency. It rotates at a high speed while running inside, forming a longer cleaning path in the pipeline, and the cleaning brush rotates at a high speed to stir the cleaned attachments, making the cleaned attachments smaller and easier to discharge with the fluid in the pipeline
