Problems solved by technology

However, due to the small diameter of small-diameter equipment, it is difficult to arrange contact probes; similarly, due to the limitation of pipe diameter, too many probes and cables cannot be arranged; in addition, for some small pipes with relatively thick walls, the water immersion method also requires There is sufficient water sound path distance, so it is difficult to obtain good detection results by using the detection method of the existing technology

Abstract

The invention belongs to the technical field of water immersion ultrasonic non-destructive testing on the inner surface of small-bore tubular equipment in a nuclear power station and relates to an ultrasonic wave angle adjustment device in water immersion ultrasonic testing. The ultrasonic wave angle adjustment device comprises water immersion probes (2 and 4), and the ultrasonic wave angle adjustment device in the water immersion ultrasonic testing is used for adjusting the angles of ultrasonic waves generated by the water immersion probes (2 and 4); the ultrasonic wave angle adjustment device also comprises a mounting base (1), a reflecting mirror (6), a motor (7) and a reflecting mirror base (9), wherein the water immersion probes (2 and 4) and the reflecting mirror base (9) are fixed on the mounting base (1) and are arranged at appointed intervals, the reflecting mirror (6) is rotationally arranged on the reflecting mirror base (9) and faces the water immersion probes (2 and 4), the reflecting mirror (6) is connected with the stator of the motor (7), and the reflecting mirror base (9) is connected with the rotor of the motor (7). According to the ultrasonic wave angle adjustment device in the water immersion ultrasonic testing, the two water immersion probes are adopted, the locating water immersion probe and the quantifying water immersion probe are switched as required by scanning, and the ultrasonic incident angle can be adjusted remotely.

Description

technical field [0001] The invention belongs to the technical field of water immersion ultrasonic nondestructive testing on the inner surface of tubular equipment with small inner diameter in nuclear power plants. Background technique [0002] There are many small-diameter tubular equipment in nuclear power plants. According to the requirements of the ASME code, regular testing of the welds of some of the small tubular equipment is required. For equipment installed in water, water immersion ultrasonic non-destructive testing is required. [0003] For the above-mentioned equipment, some tubular equipment cannot be inspected on the outer wall due to its location, and can only be inspected from the inside. At present, the detection method usually adopted for pipe structure is contact ultrasonic detection. However, due to the small diameter of small-diameter equipment, it is difficult to arrange contact probes; similarly, due to the limitation of pipe diameter, too many probes ...
