Description

Technical Field

[0001] This utility model relates to the field of acoustic emission detection technology, specifically to an acoustic emission sensor support and fixing device. Background Technology

[0002] Acoustic emission sensors are a crucial component of acoustic emission detection systems and a significant factor influencing the overall system performance. Acoustic emission sensors are made based on the principle that the physical properties of certain materials (such as semiconductors, ceramics, piezoelectric crystals, strongly magnetic materials, and superconductors) change in response to external measurands. They utilize numerous effects (including physical, chemical, and biological effects) and physical phenomena, such as the piezoresistive, humidity-sensitive, thermosensitive, photosensitive, magnetic-sensitive, and gas-sensitive effects of materials, to convert measured quantities such as strain, humidity, temperature, displacement, magnetic fields, and gas into electrical quantities.

[0003] Existing acoustic emission sensor mounting devices use magnetic bases as adsorption mechanisms to fix the sensor to the detection surface of ferromagnetic materials. For non-ferromagnetic materials, magnets cannot achieve the desired adsorption. Currently, there are no dedicated mounting supports, and workers typically use belts, tape, or elastic ropes to secure the sensor by binding it tightly around the surface. This method is not only time-consuming and labor-intensive but also prone to loosening, preventing the probe from adhering firmly to the detection surface and affecting detection results.

It solves the core problem of fixing sensors on non-ferromagnetic materials, achieving functions such as stable support, continuous good contact, and flexible adjustment. This effectively improves the detection efficiency and reliability of acoustic emission detection, especially on non-ferromagnetic material equipment.

Under the action of the first spring 105, the locking block 104 and the locking hole 201 cooperate to achieve fixation. When unlocking, it is only necessary to pull the locking block 104 section.
