During the testing process, it is usually necessary to arrange multiple probes and move the probes repeatedly to find a suitable testing position. In the prior art, the probes of the acoustic emission instrument are generally coupled and fixed to the outer surface of the pressure vessel by magnetic attraction, tape binding, spring clips or fastening bolts, but cannot meet the needs of quickly disassembling and assembling the mobile probe on non-magnetic materials.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example

[0022] like Figure 1-4 As shown, in this embodiment, a probe arrangement device for an acoustic emission detector is mainly disclosed, which is suitable for the rapid fixing and disassembly and movement of a probe 3 when the acoustic emission detector detects non-ferromagnetic equipment. Its main structure includes a tooling module 1, a suction cup 2 and a probe 3 are installed at the bottom of the tooling module 1, the tooling module 1 is provided with an air pipe interface 4 for connecting to a vacuum pump 7, and a connecting hole 5 connecting the air pipe interface 4 and the suction cup 2 is provided inside the tooling module 1. Specifically, the vacuum pump 7 is connected to the suction cup 2 through the air pipe interface 4 and the connecting hole 5, and negative pressure is continuously generated, so that the suction cup 2 is stably adsorbed on the surface of the device to be detected, and it should be ensured that the probe 3 is always in contact with the surface of the device to be detected. When the probe 3 needs to be moved, the vacuum pump 7 stops working and the suction cup 2 is sucked. When the negative pressure in the disk 2 is weakened, the probe 3 can be removed, and quick disassembly and movement can be achieved, which improves the efficiency of arranging the probe 3 and finding a suitable monitoring position, avoids the risk of the probe 3 falling due to weakened adsorption force, and improves the stability of detection. It should be noted that the air pipe interface 4 can be arranged on the side or top of the tooling module 1. The arrangement device does not have high requirements on the roughness and cleanliness of the equipment surface. The continuous output of the vacuum pump 7 can distribute the probe 3 on the surface of the non-ferromagnetic equipment for a long time. The suction cup 2 can adopt a rubber vacuum suction cup 2. A plurality of suction cups 2 can be arranged evenly at the bottom of the tooling module 1. The number of suction cups 2 is set according to the size of the probe 3 to ensure that the probe 3 can stably contact the surface of the equipment to be tested.

[0023] Furthermore, in a specific implementation, the connecting hole 5 provided in the embodiment of the utility model includes through holes 51 that are mutually cross-connected on a horizontal plane and vertical holes 52 that are arranged vertically. The ends of the through holes 51 are sealed with plugging parts 53. The through holes 51 are connected to the trachea interface 4, and the suction cup 2 is connected to the through holes 51 through the vertical holes 52. It should be noted that in order to facilitate the processing of the connecting holes 5 inside the tooling module 1, the connecting holes 5 can be in the form of through holes 51 that are mutually vertically cross-connected and penetrate the tooling module 1, and are connected to the through holes 51 through the vertical holes 52 at the bottom of the suction cup 2. At the same time, the end of the through hole 51 is blocked by the plugging part 53 to form a ventilation channel connecting the vacuum pump 7 and the suction cup 2. Specifically, the plugging part 53 can be a pipe plug, a bolt or a cover plate to prevent cross-gas pressure relief. The specific structure of the pipe plug, the bolt or the cover plate and the sealing method with the end of the through hole 51 are well known to those skilled in the art and will not be repeated here.

[0024] Furthermore, in a specific implementation, a mounting groove 11 is provided at the bottom of the above-mentioned tooling module 1 provided in an embodiment of the utility model, and a spring 6 connected to the probe 3 is fixed at the bottom of the mounting groove 11, and the end of the probe 3 extends out of the mounting groove 11. It should be noted that in the natural state of the spring 6, the height of the lower end of the probe 3 extending out of the mounting groove 11 is greater than the natural thickness of the suction cup 2, so that when the suction cup 2 is adsorbed on the surface of the equipment, the probe 3 is always subjected to the pressure of the spring 6 to maintain a certain pressing force and contact with the surface of the detection equipment, thereby ensuring the coupling effect and stability of the probe 3; in addition, a wiring groove 12 for avoiding the data line of the probe 3 is also provided at the bottom of the tooling module 1, and the mounting groove 11 is connected to the side wall of the tooling module 1 through the wiring groove 12, and the probe 3 is installed in the mounting groove 11, and the data line connected to the probe 3 for transmitting detection data passes through the wiring groove 12 from the side wall of the tooling module 1.

[0025] Furthermore, in a specific implementation, the tooling module 1 provided in the embodiment of the utility model is made of organic glass or plastic, which has good corrosion resistance and wear resistance, and prolongs the service life.

[0026] like Figure 5 As shown, in the present embodiment, a probe arrangement system for an acoustic emission detector is also disclosed, including a vacuum pump 7, a gas diverter 8 and a signal collector 9. The vacuum pump 7 is connected to the gas diverter 8 by air circuit, and a plurality of branch pipes of the gas diverter 8 are respectively connected to the air pipe interfaces 4 of a plurality of tooling modules 1. The signal collector 9 is connected to the probe 3 via a data cable, and the signal collector 9 is electrically connected to a computer for data analysis and processing. The vacuum pump 7, the gas diverter 8 and the signal collector 9 all adopt the existing technology and will not be described in detail. The arrangement system can quickly arrange a plurality of probes 3 and monitor a plurality of positions of the equipment at the same time.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
