Abstract

The invention provides a nondestructive detecting device and a detecting system which are applicable to the detection field. The device comprises a ultrasonic detecting unit, an electromagnetic detecting unit and a control unit, wherein the ultrasonic detecting unit is used for detecting defects inside an detected piece by adopting ultrasonic waves; the electromagnetic detecting unit is used for detecting defects of the surface and/or the near surface of the detected piece and stress concentration states; and the control unit is used for receiving selective information input by a user, and gating the ultrasonic detecting unit or the electromagnetic detecting unit according to the selective information, so as to output data detected by the ultrasonic detecting unit or the electromagnetic detecting unit. In the invention, through the integration of the ultrasonic detecting unit and the electromagnetic detecting unit, the nondestructive detecting device has the advantages of convenient carrying, low cost, small occupied space as well as simple detection and implementation.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a nondestructive detection device and a detection system. Background technique [0002] The non-destructive testing of nuclear power plants plays an important role in ensuring the safe operation of nuclear power plants. The existing non-destructive testing of nuclear power plants uses ultrasonic, eddy current, magnetic memory, magnetic flux leakage and other non-destructive testing methods to test related test parts of nuclear power plants. [0003] Existing nuclear power plant non-destructive testing equipment only has a single testing method. When implementing multi-method testing on a specific inspected piece in order to achieve a complete evaluation of the quality of the inspected piece, it is necessary to carry multiple testing equipment, occupying a lot of on-site space, and complex disassembly and wiring. [0004] To sum up, the existing non-destructive testing device ha...
