Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to a patrol ultrasonic wall thickness detection system. Background Technique

[0002] The ultrasonic wall thickness detection technology has important applications in the safety monitoring of industrial equipment. Especially for highly corrosive environments in fields such as petrochemical and energy, it is crucial to timely grasp the wall thickness changes of pipelines and pressure vessels to ensure production safety. The traditional detection method mainly relies on manually holding an ultrasonic instrument for single-point thickness measurement. The operator needs to detect tens of thousands of measurement points one by one, which takes a long time for each single point and requires frequent application of coupling agent to ensure measurement accuracy. In the prior art, the installation method of ultrasonic thickness measurement sensors mostly adopts temporary coupling agent application combined with manual fixation. This structural design causes gaps to easily occur between the sensor and the pipe wall due to temperature changes or mechanical vibrations, and it is necessary to regularly maintain and reapply the coupling agent, which not only increases labor costs but also causes measurement errors due to uneven application of the coupling agent. At the same time, the existing interface units are scattered in layout, and there is no unified correspondence between the detection channels and the sensor positions. During patrol inspection, it is necessary to repeatedly confirm the measurement point information, further reducing the detection efficiency. The above structural defects make it difficult for the existing ultrasonic wall thickness detection system to balance the requirements of low cost, high precision, and long-term maintenance-free operation, becoming a technical bottleneck restricting the timeliness of industrial equipment health management.
