Petroleum pipeline cleaning and detecting robot

Abstract

The invention discloses a petroleum pipeline cleaning and detecting robot. The petroleum pipeline cleaning and detecting robot comprises a walking mechanism, a cleaning and detecting mechanism and a control mechanism; the walking mechanism is provided with an axis motor, through forward and reverse rotation of the motor, lead screws are driven to rotate, then lead screw slide blocks and slide rodsare made to move to the two sides or to the middle, and the height of a transverse beam and the height of wheels are changed to achieve diameter varying, so that different pipe diameters are adaptedto; the control mechanism is provided with a control module and gear sets which are covered with a shell, the control module of the control mechanism comprises a power source, a motor and a single-chip microcomputer, and the control mechanism is furthermore connected to the walking mechanism through a support, and conducts information interaction with the axis motor of the walking mechanism and pressure sensors at the legs; the cleaning and detecting mechanism covers the outer side of the control mechanism, and through the arrangement of a runner, a replaceable tool, a brush and a detection instrument are carried. The overall structure of the petroleum pipeline cleaning and detecting robot is annular, the influence of the robot on the flow of fluid of a pipeline caused when the robot worksin the pipeline can be effectively lowered, the efficiency of cleaning and detecting the pipeline is improved, and the petroleum pipeline cleaning and detecting robot has the advantages of being reasonable in structure, high in working efficiency and strong in 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.
