Abstract

The invention belongs to the technical field of pipeline detection, and discloses an interior detection device of a pipeline; the device comprises a moving carrier which moves in a pipeline along with fluid in the pipeline or moves through an advancing mechanism and at least two groups of probe detection assemblies; and the axis of the moving carrier is parallel to the axis of the pipeline during moving; each probe detection assembly is sequentially arranged on the outer side of the moving carrier along the axis of the moving carrier; each probe detection assembly comprises a plurality of detection parts which are arranged around the axis of the moving carrier, each detection part is provided with an elastic detection end made of an elastic material, a detection probe is arranged in each elastic detection end, and the elastic movement direction of the elastic detection ends is the radial direction. According to the probe detection assembly, the state that the probe detection assembly abuts against and is attached to the inner wall of the pipeline can be kept all the time during detection, and then the signal quality and the detection accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and in particular relates to an in-pipeline detection device. Background technique [0002] Pipeline integrity is an important factor related to the safety of oil and gas transportation. Pipeline owners are very concerned about this. Failure of pipeline integrity due to pipeline corrosion or oil drilling and other damage methods will lead to major economic losses, environmental and social impacts; therefore, it is necessary to Regularly inspect the pipeline to find failures such as corrosion, deformation and leakage of the pipeline. [0003] Regarding the internal quality inspection of pipelines, the commonly used detection technologies include magnetic flux leakage (MFL), EMAT, piezoelectric ultrasonic, etc., and the most widely used is the magnetic flux leakage detection technology. Existing in-pipe detection devices are generally divided into multiple sections, and each section per...
