An oil pipeline cleaning and detection robot

Abstract

An oil pipeline cleaning and testing robot, including a traveling mechanism, a cleaning and detecting mechanism, and a control mechanism; wherein the traveling mechanism is provided with an axial motor, which drives the screw to rotate through the forward and reverse rotation of the motor, and then makes the slider of the screw and the slider move to both sides or Intermediate displacement, changing the height of the beam and the height of the wheel to achieve variable diameter to adapt to different pipe diameters; the control mechanism is equipped with a control module and a gear set wrapped in a shell, and its control module includes a power supply, a motor and a single-chip microcomputer. on the walking mechanism, and interact with the axis motor of the walking mechanism and the pressure sensor of the leg; the cleaning and detection mechanism is wrapped outside the control mechanism, and the replaceable cutter, brush and detection instrument are carried by setting the runner; the overall structure of the invention is a circle The ring shape can effectively reduce the influence of the robot on the fluid flow of the pipeline when it is working on the pipeline, and improve the efficiency of pipeline cleaning and detection. It has the advantages of reasonable structure, efficient work and strong practicability.

Description

technical field [0001] The invention relates to a robot, in particular to an oil pipeline cleaning and detection robot. Background technique [0002] As an important method of long-distance oil transportation, pipeline transportation has greatly reduced the cost of oil transportation, but there are also many problems in pipeline transportation, the most prominent one is the problem of pipeline maintenance. As a high-viscosity fluid containing crude oil, natural gas, water and other media, petroleum can easily cause pipeline blockage, thereby increasing the resistance of pipeline transportation, but some components will still precipitate wax, causing pipeline blockage, and complicated The composition will cause electrochemical corrosion of the pipeline, ranging from pipeline leakage to severe pipeline burst, polluting the environment. Therefore, regular cleaning and inspection of oil transportation pipelines is necessary. [0003] Since oil transportation pipelines are buri...

Problems solved by technology

As we all know, the closer the fluid in the pipeline is to the center of the pipeline, the faster the flow velocity is. However, the main structure of the general pipeline cleaning robot is cylindrical. When working, the main structure is in the center of the pipeline, which will hinder the flow of fluid and cause the resistance in the pipeline to increase.
