Pipeline detection robot

Abstract

The invention discloses a pipeline detection robot which is arranged in a fluid conveying pipeline and comprises a mobile carrier, and a power module, a primary control module, a positioning module and a pipeline detection module arranged on the mobile carrier. The power module, the primary control module and the positioning module are arranged on the mobile carrier; the power module, the positioning module and the pipeline detection module are electrically connected with the primary control module; the positioning module is used for positioning a geographic space position of the mobile carrier; and the pipeline detection module is connected with the mobile carrier and is used for detecting whether the state along the pipeline is abnormal or not. The pipeline detection robot is simple in structure and convenient to use; and the robot only needs to be put in the pipeline after being started, so that the robot moves in the pipeline along a material flowing direction, the pipeline state at a current position point is detected through the carried pipeline detection module, and in addition, the positioning module can jointly provide the state distribution information along the pipelineaccording to the combination of positioning information and a result detected by the pipeline detection module at the same time.

Description

technical field [0001] The invention relates to a robot, in particular to a pipeline detection robot. Background technique [0002] The submarine oil and gas pipeline is the lifeline of oil and gas transportation. Due to the advantages of large transportation volume, stable and reliable operation, high transmission efficiency, relatively low cost, and less affected by climatic conditions, it has always been the best choice for oil and gas transportation. choose. However, with the increase of the operating life of the pipeline, the variety and complexity of the operating conditions, and the impact of the submarine geological environment and the erosion of the submarine current, it is inevitable that the pipeline will be displaced, deformed, corroded, leaked, suspended and form a free span, etc. A series of problems; and after the submarine pipeline is suspended, there will be accompanying pipeline vibration, resulting in fatigue damage, accelerated corrosion and crack propag...

AI Technical Summary

Problems solved by technology

[0004] 1. The cost of testing is high, time-consuming and labor-intensive. The main reason is that a large number of sea vessels and high-tech equipment need to be used;

[0005] 2. There are personnel risks and limited by factors such as sea conditions and environmental conditions. Traditional testing often cannot be arranged in a timely manner according to needs. Factors to be considered include availability of personnel, equipment and support ships, weather conditions, sea conditions, mobilization and demobilization preparations, and Planning, etc., especially after a storm or typhoon, the inspection before resumption of production cannot be completed quickly, which will affect production;

[0006] 3. Many instruments and equipment are used, which increases the risk of personnel and equipment, such as equipment loss or personnel injury accidents, etc.

In addition to the reliability shortcomings of false positives and negative negatives, especially the detection and precise location of tiny leaks are far from meeting the requirements of practical applications.

There is a sonic ball detection technology that also uses similar leakage noise detection, but it can only detect leakage alone, resulting in high detection costs and limited applications
