Abstract

The invention relates to a novel plugging releasing and pipeline cleaning device which comprises a body, a first-level cup, a second-level cup, a motor shell, a rotating body and a scraper. The first-level cup and the second-level cup are embedded in grooves in the outer portion of the body, a valve seat is arranged between the body and the motor shell, and a compression spring is arranged between the valve seat and the motor shell. A valve deck is screwed to the rear end of the body, and a screw rod is arranged in stator rubber and connected with an input shaft through threads. One end of an output shaft is arranged in a positioning plate, and the other end of the output shaft is connected with a cover plate through threads. The output shaft and the input shaft are connected through a universal joint, the positioning plate is arranged inside the front end of the motor shell, and the rotating body is arranged outside the front end of the motor shell. A limiting end cover is screwed to the front end of the motor shell, and the scraper is arranged between the rotating body and a baffle and connected with the rotating body through a tension spring. By means of the novel plugging releasing and pipeline cleaning device, multi-level cleaning can be achieved on the wall of an oil conveying pipeline, adjustment is convenient, and controllability is high; pipeline cleaning and plugging releasing are achieved through the mutual act of the scraper and jet fluid, the pipeline cleaning effect is good, and the plugging releasing capability is high.

Description

technical field [0001] The invention relates to a novel blockage-removing pig, which is a device used for cleaning oil pipeline dirt during crude oil pipeline gathering and transportation, and belongs to the technical field of petroleum oil pipeline gathering and transportation. Background technique [0002] Pipeline transportation has become the first choice for oil and gas transportation due to its safety, speed, efficiency, and low transportation costs. Pipeline transportation of oil and gas plays an extremely important role in the entire process of oil and gas production and development, refining, processing, storage and sales. However, due to the long-term service and long-distance crude oil transportation of the oil pipeline, there will be scales in the pipeline to varying degrees, which will affect the transportation effect, cause the pressure and flow of pipeline transportation to fluctuate, cause shock and vibration to the pipeline, or cause damage to the pipeline. ...
