Walking robot for pipeline gas detection

Abstract

The invention discloses a walking robot for pipeline gas detection, and relates to the technical field of gas detection. The walking robot comprises a supporting assembly and a walking assembly, wherein the supporting assembly is composed of a plurality of annular supports arranged at equal intervals; a plurality of mounting seats are uniformly fixed on the annular supports; the corresponding mounting seats on the two adjacent annular supports are connected and fixed through connecting rods; each connecting rod is slidably sleeved with a sliding block; a second hinged support is arranged on the upper surface of the sliding block; the connecting rod is sleeved with a spring; the walking assembly comprises supporting legs and supporting rods; one end of each supporting leg is hinged to the mounting seat; and a rolling wheel is rotationally mounted at the other end of the supporting leg. The supporting rods are pushed through elastic force of the springs to support the supporting legs, the rolling wheels on the supporting legs are tightly attached to the inner wall of the pipeline, the rolling wheels are controlled by a motor to enable the walking robot to walk in the pipeline, the gas concentration in the pipeline is detected through an infrared methane sensor, the size of the robot can be freely adjusted according to the diameter of the pipeline, and water accumulation and obstacles in the pipeline are prevented from influencing the advancing of the robot.

Description

technical field [0001] The invention belongs to the technical field of gas detection, in particular to a walking robot for pipeline gas detection. Background technique [0002] During the operation of long-distance oil and gas pipelines, they are usually corroded from both internal and external environments. Internal corrosion is mainly caused by the combined action of the transport medium, liquid accumulation in the pipe, dirt, and internal stress in the pipeline; external corrosion is usually caused by coating damage, failure, etc. produce. Internal corrosion is generally dealt with by means of condition management and adding corrosion inhibitors. In recent years, with the strengthening of pipeline operation management by pipeline owners and the strict requirements for transport media, in recent years, with the widespread popularization and application of computer technology, domestic The external detection technology has been developed rapidly, and the pipeline detection...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a walking robot for pipeline gas detection. By placing the walking robot in the pipeline that needs to be detected, the supporting legs are pushed up by the spring force to push the support rods, so that the rollers on the supporting legs are close to the inner wall of the pipeline. , the motor controls the roller to make the walking robot walk in the pipeline and the gas concentration in the pipeline is detected by the infrared methane sensor, which solves the problem that the existing pipeline exploration equipment cannot adjust the size of the equipment, and it is easy to overturn and the exploration is difficult.
