Abstract

The invention provides a pipeline detection robot based on probe detection, belonging to the technical field of pipeline leakage detection. The pipeline detection robot comprises a machine body, a pressure balancing contraction air bag, a switching interface, a hose, a storage battery, a travel mechanism and a rubber cup. The pipeline detection robot detects a leakage point on the inner wall of a pipeline through a probe of a leakage point detection device, records a displacement through a mileage wheel when the detection device works, and balances an internal and external pressure difference of the leakage point detection device through the pressure balancing contraction air bag. The pipeline detection robot disclosed by the invention does not require power, has a simple structure and strong practicability, and can be widely applied to detection of petroleum and nature gas pipelines.

Description

technical field [0001] The invention belongs to the technical field of pipeline leakage detection, in particular to a pipeline detection robot based on probe detection. Background technique [0002] As we all know, the main means of transportation of oil or natural gas is pipeline transportation. With the rapid development of the pipeline transportation industry, there are more and more pipelines, and the transportation distance is getting farther and farther. [0003] As the use time continues to increase, the pipe wall will inevitably have defects caused by various reasons, such as human-induced leaks in the pipe; cracks in the pipe caused by external force; leaks caused by corrosion of the pipe when electrochemical reactions occur. Such defects may be extremely small or exist for a long time, making it difficult for general inspection systems to find them. The fluids transported in the pipeline are dangerous and polluting, such as oil and natural gas. Once a leakage acci...
