Abstract

The invention relates to a detecting device for detecting the deformation of the oil and gas transmission pipeline, which is applied to the nondestructive detection of the oil and gas transmission pipeline. The detecting device comprises a main body, a guide leather cup, a measuring leather cup, a sensor stay bar, a leather cup tightening spring, a linear displacement sensor, a driving leather cup, an odometer wheels direct supporting arm, an odometer wheel, an odometer wheels oblique supporting arm and a measuring leather cup retaining ring. The main body is provided with an information storehouse and a battery storehouse. The leather cup tightening spring and the linear displacement sensor are uniformly arranged on the main body excircle. The detecting device of the invention can complete the deformation detection of the pipeline, and determine the deformation position of the pipeline, namely the detecting device is driven via pressure difference (oil, water or gas) and runs in the pipeline; the measuring leather cup clings the pipe wall and changes with the pipe wall; the change information is stored in a storage; two odometers on the detecting device measure the travel distance, and the odometer information is also stored in the storage; when the detecting device runs out of the pipeline, the information is taken out to process comprehensive analysis and calculation so as to realize the detection of the pipeline.

Description

technical field [0001] The invention relates to a detection device for detecting the deformation of an oil and gas transmission pipeline, which is applied to the non-destructive detection of the oil and gas transmission pipeline. Background technique [0002] In the development of offshore oil and gas resources, our country has formed a crisscross submarine oil network. After the onshore and offshore oil and gas transmission pipelines are put into operation, they have been subjected to geological changes, medium corrosion, ocean currents and other factors for a long time, and are prone to defects such as deformation, corrosion and cracks. It is necessary to find these defects in time to prevent oil and gas leakage. Defect detection requires very small pipeline deformation. Therefore, before the pipeline defect detection, if the deformation detection in the pipeline is not carried out, it is very easy to cause the pipeline defect detection instrument to be stuck in the pipe s...
