Problems solved by technology

[0005] However, the existing wall fixing devices for acoustic emission sensors are generally directly fixed by bolts, and the internal acoustic emission sensors are prone to shaking, and the stability is relatively poor
[0006] Therefore, in order to solve this problem, it is necessary to develop and design an acoustic emission sensor wall fixing device, which solves the problem of poor stability of the existing acoustic emission sensor wall fixing device

Embodiment 1

[0029] see Figure 1 to Figure 2 , a wall fixing device for an acoustic emission sensor, comprising an acoustic emission sensor body 3, a threaded rod 15, a stud 19, a limiting plate one 5 and a limiting plate two 18, the acoustic emission sensor body 3 is embedded in the mounting shell 1 Inside, the installation shell 1 plays a protective role and can prevent it from being damaged by impact

[0030] The limiting plate one 5 is slidably connected in the slide rail 11 embedded in the inner wall of the installation housing 1 through the slide bar 13, the limiting plate one 5 plays the role of limiting, and can prevent the acoustic emission sensor body 3 from being placed in the installation housing 1. Shaking from side to side, it has the characteristics of good stability. The end of the slide bar 13 is connected to the top of the connecting rod 10 through the pivot pin 12, and the bottom of the connecting rod 10 is connected to the gear 9 through the pivot pin 18. The connectin...

Embodiment 2

[0036] see Figure 1 to Figure 4 , a wall fixing device for an acoustic emission sensor, further comprising a limiting plate 2 18, the bottom of the limiting plate 18 is fixedly connected with a fixing pin 21, and the fixing pin 21 is embedded in a through hole provided on the surface of the buffer block 2 17 Inside, the side wall of the fixing pin 21 is sleeved with a damping spring 1 22, and the limiting plate 1 5 is connected to the buffer block 1 4 through the shock absorbing spring 2 23, and the buffer block 1 4 and the buffer block 2 17 can prevent acoustic emission The sensor body 3 is worn and plays a protective role. The shock absorbing spring 1 22 can weaken the longitudinal force of the AE sensor body 3 from the limit plate 18 in the process of violent shaking, and the shock absorbing spring 2 23 can weaken the force in the violent shaking process. During the process, the acoustic emission sensor body 3 is subjected to a lateral force from the limiting plate-5, whic...

Description

technical field [0001] The invention belongs to the technical field of acoustic emission sensor installation, and in particular relates to a wall fixing device for an acoustic emission sensor. Background technique [0002] The acoustic emission sensor is an important part of the acoustic emission detection system and an important factor affecting the overall performance of the system. The unreasonable design of the acoustic emission sensor may cause a large difference between the received signal and the desired acoustic emission signal, which directly affects the authenticity of the collected data and the results of data processing. In acoustic emission detection, most of them use resonance Acoustic emission sensors and broadband response acoustic emission sensors. [0003] Acoustic emission sensors are made using the principle that the physical properties of certain substances (such as semiconductors, ceramics, piezoelectric crystals, ferromagnets and superconductors, etc....
