Description

Technical Field

[0001] The present disclosure relates to the technical field of sensors, and particularly to a sensor positioning device. Background Art

[0002] The acoustic emission signals propagating in a solid medium contain characteristic information of the acoustic emission source. To utilize this information to reflect the material properties or the development state of defects, it is necessary to receive such acoustic emission signals on the solid surface. Receiving, processing, analyzing, and displaying the acoustic emission signals is the process of processing the acoustic emission signals. Therefore, the accuracy of receiving the acoustic emission signals will affect the success rate of the test, and further affect the exploration of the crack propagation law of the specimen. Therefore, the accuracy rate of receiving the acoustic emission signals will affect the quality of the acoustic emission test. In the existing acoustic emission tests, when conducting acoustic emission tests on rocks, concrete, etc., there is no special fixing device for the used acoustic emission sensors. Mostly, tape or rubber bands are used to fix the acoustic emission sensors, and butter or vaseline is applied on the acoustic emission sensors and the rock specimens to achieve contact between the specimen and the acoustic emission. The above measures cannot ensure good coupling between the acoustic emission sensor and the surface of the rock specimen. During the test process, the rock specimen expands radially under pressure, and fixing devices such as tape are likely to cause strong restraint on the acoustic emission receiver, and even cause certain damage. Fixing devices such as rubber bands are likely to cause the sliding of the acoustic emission sensor, affecting the positioning effect of the test and causing the interruption of the test and affecting the test process. At the same time, for the above two fixing methods, it is difficult to ensure the consistency of the force on the acoustic emission sensor, resulting in errors in the signals received by the sensor, affecting the analysis and judgment of the test results.

[0003] In summary, the existing technology lacks an effective fixing device for the acoustic emission sensor to achieve stable reception of the acoustic emission signals, and the existing technology cannot break through the size limitation of the test specimen. Summary of the Invention

Specifically, the diameter adjusting device 3 comprises a second slider 31 and a connecting rod 32. The second slider 31 is used for sliding engagement with the extension 22, so that the second slider 31 moves along the diameter direction of the base 1.
