Intelligent speed-control blade type pipe cleaner

Abstract

The invention relates to an intelligent speed-control blade type pipe cleaner which is mainly composed of a plurality of steel blades, a plurality of mileage wheels, a mandrel, a motor, a single-chipmicrocomputer, a drainage device and other components. A plurality of steel blades are designed, a plurality of blade layers are arranged around the mandrel, the blade layers are closely attached to apipe wall for scraping and cleaning a pipe under the preset pressure of springs, and blockage can be avoided through the retraction capacity of the blades under resistance; meanwhile, the mileage wheels are arranged around the mandrel and record displacement, the displacement is converted into speed signals through a speed sensor, the speed signals are transmitted to the single-chip microcomputer, the single-chip microcomputer controls the motor to act, the motor controls a drainage baffle to rotate, and therefore the front-back pressure difference of the pipe cleaner is adjusted, and the speed is reduced. Compared with an existing conventional pipe cleaner, the intelligent speed-control blade type pipe cleaner is lower in price, it is ensured that the pipe cleaning efficiency is higher,and the pipe explosion caused when the pipe cleaner gets stuck and the pipe cleaning speed is too high is effectively avoided.

Description

technical field [0001] The invention relates to an intelligent speed-controlled vane-type pipe pig, and relates to the field of oil and gas gathering and transportation. Background technique [0002] At present, long-distance natural gas transportation relies on pipeline transportation. The pigging process is an important process to maintain the safety of the pipeline and ensure the smooth passage of the transport medium. In the process of actually cleaning the pipeline, the most common engineering problem is that the pig is easy to get stuck in the pipeline , There are many reasons for the blockage of the pig in the process of advancing. First of all, the excessive interference of the cleaning cup, the tearing of the cup, and the poor sealing of the cup lead to pressure leakage; secondly, the annulus of the inner wall of the pipeline is not a standard smooth surface in actual working conditions, and there are burrs and pits Such defects hinder the operation of the pig; at ...
