Problems solved by technology

[0005] After searching the prior art documents, it was found that "Autonomous System for Oil Pipeline Inspection" (pipeline detection automation system) published by Jun Okamoto Jr et al. on pages 731-743 of the 9th issue of "mechatronics" (mechanical electronics) in 1999, the paper proposes The probe ring carries 16 detection probes in the pipeline and rotates while moving for dynamic detection. The disadvantages are: the structure is more complicated, it is not easy to control, the data collection is not comprehensive enough, and the continuous working time is short

Abstract

A pipeline data collecting and storing detecting device of the technical field of pipeline detection includes a detecting device, a data collecting and storing device, an active connecting device and supporting wheels. The detecting device includes a detecting device housing, a plurality of detecting holes arranged on the side walls of the detecting device housing, a plurality of ultrasonic probes arranged inside of the detecting device housing and the head parts of the ultrasonic probes penetrate the detecting holes correspondingly; and a plurality of supporting wheels arranged on the detecting device housing. The data collecting and storing device includes a collecting device housing, a collecting sealing cabin arranged inside the collecting device housing, a control module arranged inside the collecting sealing cabin and the control module is electrically connected with the ultrasonic probes; a plurality of supporting wheels arranged on the collecting device housing. The active connecting device is connected to the front part of the housing of the data collecting and storing device and the back part of the detecting device housing. The embodiment of the invention has the advantages of simple structure, comprehensive detecting and long continuous working time, which can detect in a long distance.

Description

technical field [0001] The invention relates to a device in the technical field of detection, in particular to a detection device for collecting and storing pipeline data using an ultrasonic detection method. Background technique [0002] Submarine oil and gas pipelines are safe, convenient and efficient means of transportation for offshore oil and gas resources. In the 1990s, my country already had more than 20,000 kilometers of long-distance oil and gas pipelines, and quite a few of them have been in service for 20 years. Pipelines will be aged, corroded or deformed after long-term operation, so it is necessary to regularly inspect the pipelines in order to overhaul or repair the pipelines in a planned and targeted manner. However, due to the complex and changeable seabed environment, it has brought great difficulties to the detection of pipelines. These overage pipelines have not been effectively tested so far, which has brought great hidden dangers to safe production. O...
