Ultrasonic inspection of petroleum pipeline and inspecting robot

Abstract

A ultrasonic wave detection device of petroleum pipeline is prepared as setting ultrasonic probe at front end of robot body, arranging a rubber disc at tail end of robot, forming robot body by front unit and back unit as the two being connected by universal couple, applying driven wheels as traveling mechanism of robot and setting these wheels on front unit and back unit separately. Its dynamic-detecting method is also disclosed.

Description

technical field [0001] The invention relates to an ultrasonic detection method of an oil pipeline and a detection robot. Background technique [0002] The working space of the pipeline robot is a variety of complex and closed pipelines, including horizontal straight pipes, bent pipes at various angles, slope pipes, vertical pipes, and variable diameter pipe interfaces, etc., and its running distance is generally longer. Therefore, the mechanical structure of the robot must be flexible and reliable, and have a large traction force. In order to have versatility and adapt to pipeline inspections with different radii, the robot should have an adjustable radius. [0003] At present, the driving methods of the oil pipeline inspection robots that have been developed mainly include active and driven. The active type can control the movement speed of the robot, but it consumes a lot of energy, so the method of connecting cables is generally used. Powering the robot and transmitting...

AI Technical Summary

Problems solved by technology

The robot can record the detection results into the memory through the single-chip microcomputer, and the energy consumption is very low, which solves the problem of long-distance working of the pipeline inspection robot
