Abstract

The invention discloses a flexible defect detection device for a pipeline inner wall and a working method thereof, and belongs to the technical field of pipeline inner wall defect detection. The device comprises a body, an image recognition device, an electromagnetic ultrasonic detection device, a control and processing module, a flexible power mechanism and a power supply device, the image recognition device, the electromagnetic ultrasonic detection device, the flexible power mechanism and the power supply device are respectively connected with the control and processing module; the plurality of flexible power mechanisms are annularly arranged on the side part of the body; and during use, the ends of all the rollers make contact with the inner wall of the pipeline. According to the invention, human eyes are replaced, the detection efficiency is improved, and errors are reduced; the device can obtain enough support in a pipeline and stably advance; and according to the method, defects in the pipeline can be efficiently identified, efficient continuous operation can be carried out in the variable-diameter pipeline, the method does not depend on the skill level and experience of an operator, and the method has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of pipeline inner wall defect detection, and in particular relates to a flexible defect detection device for the inner wall of a pipeline and a working method thereof. Background technique [0002] Pipeline is a device used to transport gas, liquid or fluid with solid particles. It is mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The rapid growth of energy demand has promoted the rapid development of pipeline engineering construction. By the end of 2010, the total length of global pipeline trunk lines exceeded 2 million kilometers. [0003] After long-term operation, the problem of pipeline disease has become increasingly prominent. The defect of the inner wall of the pipeline is a kind of rail damage that often occurs in the process of pipeline transportation ...
