Automatic cleaning device for natural gas pipeline

Abstract

The invention discloses an automatic cleaning device for a natural gas pipeline. The cleaning device comprises a device shell and a rubber cup coaxially and fixedly installed outside the device shell; the device shell is composed of a moving assembly cavity, a collecting bin, a rotating part and a gas injection part from left to right; a telescopic moving assembly is movably installed in the moving assembly cavity, a collecting bin is coaxially and fixedly connected to one side of the moving assembly cavity, a fixing cover is fixedly installed in the collecting bin, fan blades are coaxially and rotationally installed in the fixing cover, a rotating shaft is installed on a coaxial fixing rod of the fan blades, a shaft body of the rotating shaft is rotationally connected with a motor through a chain, the motor is fixedly installed on the inner wall of one side of the collecting bin, and a lithium battery is fixedly installed in the collecting bin; a rotating part is coaxially and rotationally installed at the end, away from the moving assembly cavity, of the collecting bin through a sealing bearing, a circular through opening penetrates through the side wall, away from the collecting bin, of the rotating part, a plurality of supporting columns are fixedly installed on the inner wall of the through opening, and fixing rings are fixedly installed at the ends of the supporting columns.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline cleaning, in particular to an automatic cleaning device for natural gas pipelines. Background technique [0002] With the acceleration of urbanization in China and the start of the West-East Gas Transmission Project, large-scale pipeline systems are widely used due to their excellent work efficiency and small footprint, and a large number of oil and gas pipelines in China are distributed in the population In densely populated areas, many natural gas pipelines will form impurities such as rust, welding slag, dust, sand, and insulation materials during the processing and use of natural gas pipelines. This phenomenon seriously affects the normal use of natural gas pipelines, resulting in reduced transmission efficiency and pipeline blockages. In this regard, the authorized Chinese invention with the publication number CN107931278B discloses an automatic cleaning device for natural gas pi...

Problems solved by technology

[0003] Although this invention has high working efficiency, its structure is relatively complicated and its manufacturing cost is high, so it is not suitable for widespread promotion. At the same time, it is guided by two moving wheels, and the guiding effect is poor during cleaning. Impurities cleaned by the fixed brush still remain in the pipeline. It is easy for impurities to continue to stick to the inner wall of the pipeline after rolling, so we propose an automatic cleaning device for natural gas pipelines to solve the above problems
