Abstract

The invention belongs to the technical field of pipeline detection and discloses a posture mileage measuring device for a detector in a pipeline. The posture mileage measuring device comprises a posture mileage data processing plate, a posture measuring unit and a mileage measuring unit, wherein the mileage measuring unit is fixedly connected with the posture measuring unit; the posture measuringunit comprises a sealed posture cylinder and a posture module which is positioned inside the posture cylinder; the mileage measuring unit comprises a mileage framework and a plurality of mileage components which are rotationally connected with the mileage framework; the posture cylinder is fixedly connected with the mileage framework; the plurality of the mileage components are arranged in the circumferential direction of the mileage framework; the posture module and the mileage components are respectively connected with the posture mileage data processing plate. By adopting the posture mileage measuring device, the problems that in the prior art posture mileage data are hard to read and poor in operability are solved; modularization of a pipeline defect positioning function is achieved; the posture mileage measuring device is applicable to detectors in pipelines of multiple types, is applicable to pipelines of different apertures and has the characteristic of universalization; in addition, a specific window from which data are read is formed, and thus the posture mileage measuring device is good in operability.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and relates to a generalizable gesture mileage measuring device for a detector in a pipeline. Background technique [0002] Pipeline transportation is currently the most effective way to transport oil and natural gas. With the increase of operating life, pipelines will be damaged under the action of external forces such as corrosion and erosion, which will reduce the safety of transportation. In severe cases, accidents such as leakage and pipe burst may occur. In order to ensure the safety of pipeline transportation, it is necessary to regularly use in-pipeline detectors to detect pipelines and take maintenance measures. Most in-pipeline detectors are multi-section structures, including detection sections, power supply sections, and data sections. Defects are detected and identified. Defect detection methods can be divided into ultrasonic detection, laser detection, magnetic flux leaka...
