Abstract

The invention belongs to the technical field of nuclear power, and particularly relates to an ultrasonic scanning device. According to an annular chain structure disclosed by the invention, phased array probes with different sizes and specifications can be conveniently mounted, so that the ultrasonic probe is better attached to the outer side wall of a to-be-detected pipeline in the detection process, the movement track is stable, the detection efficiency and the reliability of a detection result are greatly improved, the length of the chain can be adjusted by increasing or decreasing the number of the connecting blocks of the chain, and the chain is flexibly suitable for pipelines with different diameters and especially suitable for ultrasonic scanning of small-diameter pipes. Besides, as the roller connected with the encoder and other rollers rotate synchronously, the angular displacement data generated by the encoder can be used for reflecting the circumferential position corresponding to the ultrasonic scanning data, and positioning and analysis of the ultrasonic scanning result are facilitated. Human errors are reduced, and defect positioning is accurate.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to an ultrasonic scanning device. Background technique [0002] Small-diameter thin-walled pipes are the parts and locations most likely to generate defects and leaks in the operation of nuclear power plants. Conventional small-diameter pipe inspections usually use methods such as radiographic inspection and conventional ultrasonic inspection. Due to its own characteristics, radiographic inspection will produce ionizing radiation during radiographic inspection, which will cause harm to the human body and the surrounding environment and the inspection cycle will be long. During the inspection, the inspection area needs to be cleared and isolated, and it cannot be operated at the same time as other inspection and maintenance work, which will closely affect the overhaul The progress of radiographic testing has low detection sensitivity for area-type defects. Although...
