Description

Technical Field

[0001] This utility model relates to the field of acoustic emission sensor technology, and specifically to a rapid installation device for acoustic emission sensors. Background Technology

[0002] Acoustic emission testing (AE) technology, as a key non-destructive testing method, is widely used in the health monitoring of mechanical structures (such as pressure vessels, bridge cables, and wind turbine blades). Its core principle is to capture stress wave signals released by internal material damage through sensors. The installation quality of the sensor directly affects the reliability and accuracy of signal acquisition, especially in complex working conditions such as outdoor, high-altitude, and high-temperature environments, where sensors are easily affected by external environmental interference, leading to inaccurate signals. Traditional fixing methods have significant technical bottlenecks. Currently, acoustic emission sensor installation devices face three major challenges: the difficulty in balancing the need for rapid installation with adaptability to complex surfaces; the inability to dynamically adjust pressure according to working conditions, resulting in large fluctuations in signal quality; and the tendency of traditional fixing methods to damage equipment surfaces or require frequent replacement of consumables (such as tape). Existing installation methods mostly use tape or clamps to fix the acoustic emission sensor to the object being measured. However, tape fixation is prone to detachment, and the tape on the acoustic emission sensor needs to be cleaned after each use. Clamp fixation is only suitable for small objects and easily fixed structural parts, and is not convenient for the installation of acoustic emission sensors. Utility Model Content

[0018] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0020] An embodiment of the rapid installation device for an acoustic emission sensor according to this utility model is as follows: Figures 1-3 As shown, the device includes a mounting bracket 1, which comprises a mounting base plate 2 and a rectangular frame 3. The mounting base plate 2 is used to attach to the object being measured. The mounting base plate 2 has grooves, each containing a magnet 19. In this embodiment, there are two grooves and two magnets at both ends of the mounting base plate. The magnets 19 are neodymium magnets. The mounting base plate 2 also has four screw holes 4. By using the magnet and screw method described above, the mounting device of this invention can be applied to various objects being measured. For objects that can be attracted by a magnet, screws are not required; the mounting bracket is directly and firmly attached to the object by the magnet. When dealing with non-magnetic objects, such as concrete or composite materials, the mounting bracket can be directly fixed to the object by screws.

[0021] The mounting bracket 4 is threaded with an adjusting screw 5, specifically, the adjusting screw 5 is mounted on the rectangular frame 3. The mounting device also includes a pressing component, which presses and fixes the acoustic emission sensor to the mounting base plate via the adjusting screw. A locking nut 7 is provided on the adjusting screw 5 to prevent loosening. In this embodiment, the pressing component includes a protective cover 8 with an opening facing the mounting base plate 2. A spring (not shown in the figure) is installed inside the protective cover. A second pressure plate 11, a pressing block 12, a first pressure plate 13, and a bottom protrusion 14 are sequentially and movably arranged between the spring and the mounting base plate inside the protective cover 8. A pressure sensor is positioned between the second pressure plate 11 and the pressing block 12, and the acoustic emission sensor is placed between the pressing block 12 and the first pressure plate 13. A spring presses against the second pressure plate, which clamps and fixes the pressure sensor with the top pressure block. The top pressure block and the second pressure plate clamp and fix the acoustic emission sensor. The second pressure plate fits against the bottom protrusion 14, which can seal against the lower inner side of the protective cover 8. This arrangement provides the protective cover with a certain degree of waterproof and dustproof function, protecting the internal pressure sensor and acoustic emission sensor. To facilitate cable routing and avoidance of the protective cover, cable grooves 17 are provided on the peripheral sides of the top pressure block, the first pressure plate, and the bottom protrusion, for the insertion of the pressure sensor cable and the acoustic emission sensor cable. Radial protrusions 15 are provided on the peripheral side of the top pressure block 12, and slots 16 are provided on the side wall of the protective cover for the radial protrusions to engage, facilitating the positioning and installation of the top pressure block.

[0022] In this embodiment, the first pressure plate 13 is a composite plate. Specifically, the first pressure plate includes a silicone layer and a metal mesh layer. The silicone layer can fill the microscopic unevenness of the surface to ensure the acoustic coupling efficiency, and the metal mesh suppresses signal distortion caused by high-frequency vibration (>500Hz). The second pressure plate 13 has the same structure and material as the first pressure plate 11. An anti-rotation structure is provided between the protective cover 8 and the mounting base plate 2 to prevent the protective cover from rotating with the adjusting screw. A protective cover edge plate 9 is provided on the outer wall of the protective cover 8. The anti-rotation structure includes at least two guide posts 18 provided on the mounting base plate and guide holes 10 provided on the protective cover edge plate 9. The guide holes 10 correspond one-to-one with the guide posts 18 and guide the vertical movement. This arrangement ensures that the protective cover will not rotate with the adjusting screw during the tightening process.

[0023] When using the acoustic emission sensor, the magnets and screw holes on the mounting plate allow it to be used on most objects, including magnetic materials and non-magnetic materials such as concrete and composite materials. Place the acoustic emission sensor between the top pressure block and the first pressure plate, and the pressure sensor between the second pressure plate and the top pressure block. Place the second pressure plate, pressure sensor, top pressure block, acoustic emission sensor, first pressure plate, and bottom protrusion together inside the protective cover. Tighten the adjusting screw to press down on the protective cover, causing it to move downwards. An internal spring compresses the second pressure plate, transmitting pressure downwards. The pressure sensor can be connected to a pressure gauge to display the pressure value in real time. The pressure readings from the pressure sensor allow adjustment of the pressure applied to the acoustic emission sensor during installation, ensuring proper installation.
