Abstract

The invention relates to a rotation jet flow type pipe cleaning device used for pipeline cleaning, detecting, pipeline coating and other pipeline construction. According to the technical scheme, a front end cover and a rear end cover are arranged at the two ends of a cylinder, packing cups are arranged at the two ends of the cylinder, overflowing holes are formed in the edges of the packing cups, a rotation sleeve is arranged in the front end cover and driven by a motor, a rotary disc and a conical sleeve are arranged at the front end of the rotation sleeve, brush heads are arranged on the periphery of the rotary disc, and a storage battery is arranged in the cylinder and connected with the motor. A conical sleeve and scraper blades are arranged at the front end of the rotation jet flow type pipe cleaning device, accumulated objects at the front end can be crushed, media jetted from the rear end and fine solid-phase particles are conveniently mixed to flow forwards, and the pipe cleaning device is not prone to being jammed.

Description

technical field [0001] The invention relates to a rotary jet type pipe pig, which is used for pipeline construction such as pipeline pigging, detection and pipeline coating. Background technique [0002] After the 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 after a period of operation ...
