Various types of conveying pipelines face various corrosion and scaling problems according to different internal media, and the internal cleaning is usually required to be carried out regularly. Especially, the inner wall of the underground oil pipe can be scaled and waxed after long-time operation, and the problems of corrosion are accompanied. After the underground pipe column is taken out, the inner surface and the outer surface of the underground pipe column need to be cleaned, and then detection and testing are carried out. Because the length-diameter ratio of the underground pipe column is larger, the inner hole of the pipeline is smaller, and the conventional manual cleaning is more complicated. At present, a downhole tubular column, particularly an underground oil pipe is taken out, and a steel wire ball and foam ball cleaning mode is mainly adopted. The steel wire ball and the foam ball are plugged into the pipeline in a conventional cleaning mode, and are pushed to pass through the inner cavity of the pipeline by water containing a cleaning agent, so that the cleaning effect can be achieved by repeated operation; or the thin rod is stretched into the pipeline and dragged back and forth to clean and scrape the inner wall of the pipeline, but the pipeline is long, so that the construction is very inconvenient.

The inside fixed mounting of pipeline has the pipeline inner wall, and the fixed surface of pipeline inner wall installs elastic element, and elastic element's top fixed mounting has the (mixing) shaft, and the even fixed mounting in surface of (mixing) shaft has stirring vane, and the outer wall fixed mounting of pipeline has the heat preservation, and the surface of heat preservation is run through and extends to in the bottom of (mixing) shaft, and the bottom fixedly connected with conical gear of (mixing) shaft is from the axle center of driving wheel. This petroleum pipeline is with wasing pull throughs, through setting up the washing pull throughs, the second motor drives the main shaft and rotates, and the main shaft drives clean brush holder and rotates, reaches the effect of more convenient washing pull throughs, and first washing connecting rod and second wash the angle modulation between connecting rod and the main shaft, reach the effect that is applicable to different internal diameter pipelines and makes the washing brush holder more closely laminate the pipeline inner wall, have solved the problem that the pipeline is blockked up by oil or iron rust. This technical scheme is fixed the (mixing) shaft to the pipeline radially, can only stir and clean pipeline local position, and can not be used for the inside of whole tubular column clean.
Patent CN208853397U discloses a cleaning device for the inner wall of oil pipeline capable of freely bending. Including brush board, brush hair, first removal wheel, swivel becket, ball bearing, first spring, first flexible interior pole, first flexible outer pole, the first in command, the fixed plate, the polishing piece, the casing, including a motor, an end cap, a controller, and a cover plate, the piston rod, the electricity jar, the second handle, the flexible outer pole of second, the flexible interior pole of second, base, the flexible outer pole of third, the second spring, the flexible interior pole of third, the wheel is removed to the second, swivel becket, the dead lever, the flexible interior pole of fourth, the flexible outer pole of third spring and fourth. The utility model has the advantages that: through mutually supporting between first flexible outer pole, first flexible interior pole and the first spring, make the adjustable size of cleaning device, can clean the defeated oil pipe of different bores, be connected through the cardan shaft between dead lever and the dead lever, make the dead lever rotation angle by oneself, install the brush on the dead lever, can sweep out the dirt in the lump when taking cleaning device out. This technical scheme adopts pipeline robot's mode, carries out the inside cleanness of pipeline, but because the restriction of structure, this type cleaning robot can only be applicable to the pipeline of big pipe diameter, and the pipeline of tubular column type in the pit is inside clean not to be adapted.
Based on the technical background, the more convenient and reliable pipeline internal cleaning device has practical significance and application prospect, and the innovation and research of the related technology have great application value.
