Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic flaw detection, and in particular to a two-dimensional mobile ultrasonic flaw detection and positioning device. Background Art

[0002] Ultrasonic flaw detection is a technology that uses the acoustic properties of materials and changes in internal structures to affect the propagation of ultrasonic waves when they propagate in the material being tested. By detecting the degree of influence and condition of ultrasonic waves, the performance and structural changes of materials can be understood. When ultrasonic waves encounter the interface between two different media or materials of different densities, they will be refracted or reflected at the interface. Using this characteristic, ultrasonic waves can be emitted to the workpiece being tested, and the receiving probe can receive the ultrasonic waves reflected from the defects or bottom surface or the transmitted waves after passing through the workpiece being tested, so as to detect whether there are defects in spare parts, and locate, quantify and characterize the defects.

[0003] However, after use, it is not convenient to clean the ultrasonic probe of the mobile ultrasonic flaw detection and positioning device in the prior art, which causes the surface of the ultrasonic probe to be easily contaminated with coupling agent, making it inconvenient to use next time. In addition, the existing ultrasonic flaw detection mechanism is not convenient to clean the surface of the material to be tested, resulting in that the dirt on the surface of the material to be tested may hinder the coupling agent from fully contacting the surface of the object to be tested, resulting in poor coupling effect, affecting the propagation efficiency of the ultrasonic wave, causing part of the ultrasonic wave energy to be reflected or scattered at the interface between the dirt and the coupling agent, thereby reducing the accuracy of the detection. In addition, it is difficult for the mobile ultrasonic flaw detection and positioning device in the prior art to evenly apply the coupling agent to the surface of the object to be tested when in use. The uneven thickness of the coupling agent can easily cause the instability of the ultrasonic signal, which increases the signal fluctuation during the detection process and makes it difficult to obtain a stable detection result. In addition, the mobile ultrasonic flaw detection and positioning device in the prior art is not convenient for positioning the ultrasonic flaw detection device when it is moving, and it is difficult to ensure that the ultrasonic flaw detection device maintains stable and directional movement when moving, causing the ultrasonic flaw detection device to easily deviate from the original trajectory when moving, thereby affecting normal detection.
