Title:
PIPELINE NONDESTRUCTIVE TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/015675
Kind Code:
A1
Abstract:
A pipeline nondestructive testing device, which relates to the technical field of nondestructive testing. The pipeline nondestructive testing device comprises a moving carrier (1), which moves in a pipeline along with a fluid in the pipeline or moves by means of a traveling mechanism; and a probe detection assembly (2), wherein the probe detection assembly (2) comprises a detection component mounted on the moving carrier (1), the detection component is provided with a detection end, and a detection probe (24) is encapsulated in the detection end. A data processing unit, a first signal conditioning unit, and a second signal conditioning unit are further comprised. The detection probe (24) comprises an excitation coil, a receiving coil, and a passive resonance coil, and the passive resonance coil is located between the excitation coil and the receiving coil. A magnetization treatment device does not need to be additionally introduced during testing, such that the volume of a system is greatly reduced, thereby reducing the requirement of a testing system for the cleanliness of the interior of a pipeline, improving the pipeline passing ability of the testing system, and greatly reducing the cost overheads of the system.
