Conveniently positioning type pipeline cleaning robot

Abstract

The invention relates to the technical field of pipeline cleaning technology, in particular to a conveniently positioning type pipeline cleaning robot. Axial linear motor telescoping is used to driveopening and closing of a scraping assembly through a connecting rod bracket, the cleaning work of inner walls of pipelines of different diameters is adapted, and the applicability is high; a driving motor is used to drive fan blades to rotate, through guiding by a blade cover and by utilizing in-pipe fluid to generate a propulsion force, movement of the robot is realized; the driving motor rotates, meanwhile, a cleaning assembly is driven to rotate through power transmission, so that the pipeline inner wall is cleaned, and the effect is high; the scraping assembly adopts detachable assembly tofacilitate the installation and replacement; spring rods are used as the supporting part to adapt to the pipeline support in pipelines of different diameters, and rollers are matched for moving; anda radial linear motor is used to drive a pressure plate to move, the robot is propped up when the driving assembly stops, the robot is positioned in the pipeline, and the robot shifting due to self flowing of in-pipe fluid is avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a convenient positioning type pipeline cleaning robot. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] Pipelines are commonly used transportation carriers. Pipelines play a very important role in current production and life. They can not only play the role of energy transmission, but also the main way ...

Problems solved by technology

[0004] However, as we all know, after long-term use of the pipeline, dirt will remain on the inner wall more or less, which will affect the normal use; however, there are currently many automatic pipeline cleaning devices, especially for the cleaning of the outer wall of the pipeline, such as wrap-around and three-wheel cleaning devices , this is because it is more difficult to clean the inner wall of the pipe than the outer wall

At present, the cleaning of the inner wall of the pipeline is mainly realized by the rotation of the circular brush, but since the device needs to move in the pipeline, the contact friction between the circular brush and the pipeline wall should not be too large, otherwise it will hinder the movement of the device in the pipeline, which in turn will cause cleaning The cleaning effect is not ideal when cleaning the inner wall

[0005] Therefore, the existing cleaning of the inner wall of the pipeline is mostly manual cleaning or replacement. The former has a large manual workload, and the latter has a high replacement cost.

[0006] And in practice, there is generally fluid in the pipeline, and the pipeline needs to be cleaned online, but most of the cleaning robots in the prior art only consider cleaning the pipeline alone, so generally only equipped with a driving component, simply think that the driving component stops Turning, the device will stop immediately, and the positioning of the inverted device in the pipeline has not been considered. In fact, if a motor is used to drive the roller drive assembly, not only the structure is biased, but also after the motor stops, most of the device will be pushed by the fluid, resulting in The position is shifted, affecting the cleaning work
