Technical Field
[0001] The present application relates to the technical field of signal detection devices, and in particular to an acoustic vibration detection device with a dustproof function. Background Art
[0002] GIS (gas insulated switchgear) has been widely used in various power grid systems due to its strong systematization, high integration, small footprint, and good reliability. However, there is a big contradiction between the current safety monitoring level of GIS and the rapid development of the power grid system. With the increase in the density of the power system, the failure rate of GIS is increasing.
[0003] Under the action of electromagnetic stress and mechanical vibration, or due to changes in inherent mechanical properties, the defective position in the GIS will produce abnormal vibrations and emit abnormal vibrations and sounds that are different from those during normal operation of the equipment. Therefore, these signals can be used as the basis for defect location and diagnosis. This method is a non-contact detection method that is independent of the equipment and is not affected by the electromagnetic environment.
[0004] However, there are some problems in the use of existing acoustic vibration detection devices. Due to the operation of internal electrical components, the device generates a lot of heat, so high heat dissipation performance is required. The heat dissipation holes of existing acoustic vibration detection devices are large and are easily infiltrated by impurities such as dust. Utility Model Content

[0020] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.
[0021] See also Figures 1 to 4 , the present application provides an acoustic vibration detection device with dustproof function, comprising:
[0022] A detection device body 1 is provided with a heat dissipation hole 3 on the side of the detection device body 1, a fixing component 2 is arranged inside the outer shell of the detection device body 1, a dustproof net 4 is fixedly installed inside the heat dissipation hole 3 through the fixing component 2, a plug-in slot 7 is provided on one side of the heat dissipation hole 3, a plug-in rod 8 is integrally connected to one side of the dustproof net 4, and the plug-in rod 8 is fixedly plugged into the plug-in slot 7.
[0023] In the present application, the detection device body 1 is a conventional acoustic vibration detection device, which is used to realize the related functions of acoustic vibration detection. In order to ensure that the detection device body 1 can maintain good heat dissipation performance during long-term operation and avoid damage or failure caused by overheating, a heat dissipation hole 3 is opened on the side of the detection device body 1.
[0024] The heat dissipation hole 3 is a special structure, and its function is to effectively conduct the heat inside the detection device body 1 to the outside, thereby reducing the operating temperature of the device. In order to improve the heat dissipation effect, a fixing component 2 is provided inside the shell of the detection device body 1. These fixing components 2 can be metal brackets, screws or other fasteners, which tightly connect the heat dissipation hole 3 with the internal structure of the detection device body 1 to ensure that the heat can be smoothly conducted from the inside to the outside.
[0025] In order to prevent dust and other impurities from entering the detection device body 1 and affecting the normal operation of the device, a dustproof net 4 is fixedly installed inside the heat dissipation hole 3 through a fixing component 2. The dustproof net 4 is a material with good air permeability and dustproof performance, which can effectively prevent external dust and impurities from entering the detection device body 1, while ensuring that heat can be smoothly conducted from the heat dissipation hole 3 to the outside.
[0026] In order to facilitate the installation and replacement of the dust screen 4, a plug-in slot 7 is provided on one side of the heat dissipation hole 3. The plug-in slot 7 is a specially designed groove, and its shape and size match the plug-in rod 8 on the dust screen 4. When the dust screen 4 needs to be installed or replaced, the plug-in rod 8 only needs to be inserted into the plug-in slot 7 to achieve a tight connection between the dust screen 4 and the detection device body 1.
[0027] The detection device body 1 achieves good heat dissipation and dustproof performance by setting structures such as heat dissipation holes 3, fixing components 2, dustproof net 4, plug-in slots 7 and plug-in rods 8, thereby ensuring the stability and reliability of the equipment during long-term operation.
[0028] A mounting flange 5 is integrally provided at the bottom of the detection device body 1 , and an insulating mounting plate 6 is fixedly installed at the bottom of the mounting flange 5 . The insulating mounting plate 6 is coaxially arranged with the mounting flange 5 .
[0029] The bottom of the detection device body 1 is integrally provided with a mounting flange 5. The mounting flange 5 is designed to facilitate the fixed connection between the detection device body 1 and an external device or structure. It is assembled with the external device or structure through fasteners such as bolts and nuts, thereby achieving stable installation of the detection device body 1.
[0030] An insulating mounting plate 6 is fixedly mounted on the bottom of the mounting flange 5. The function of the insulating mounting plate 6 is to ensure that the detection device body 1 is electrically isolated from the outside world to prevent safety hazards caused by short circuits or other electrical failures. At the same time, the insulating mounting plate 6 can also improve the stability of the entire device and extend its service life.
[0031] It is worth noting that the insulating mounting plate 6 and the mounting flange 5 are coaxially arranged. This means that no matter from which direction they are viewed, they are located on the same center line. This design helps to maintain the overall balance of the detection device body 1 and avoid tilting or shaking during use.
[0032] The outer shell of the detection device body 1 is provided with a through slot, and the top and bottom of the dustproof net 4 are connected with a fixing cylinder 9 which is clamped with the fixing component 2 .
[0033] In addition, a through slot is provided on the outer shell of the detection device body 1. The function of this through slot is to allow the dust screen 4 to be embedded in the detection device body 1 and to be engaged with the fixing component 2. This not only realizes the installation of the dust screen 4, but also ensures the cleanliness and safe operation of the inside of the detection device body 1.
[0034] Specifically, the top and bottom of the dust screen 4 are connected with fixed cylinders 9 that are snap-fitted with the fixing assembly 2. These fixed cylinders 9 are used to firmly fix the dust screen 4 on the detection device body 1 to prevent it from loosening or falling off. At the same time, since the fixed cylinders 9 and the fixing assembly 2 are snap-fitted, when the dust screen 4 needs to be replaced, it can be easily removed by simply turning the fixing assembly 2, which is very convenient.
[0035] The fixing assembly 2 includes a rotating shaft 21 rotatably connected to the inner shell of the detection device body 1, and the outer circumferences of the two rotating shafts 21 are fixedly installed with clamping blocks 22, and the outer circumferences of the two rotating shafts 21 are fixedly installed with gears 23 located above the clamping blocks 22. The two gears 23 are meshed, and the outer circumference of one rotating shaft 21 is fixedly installed with a ratchet 24 located above the gear 23.
[0036] The outer circumferential surface of the clamping block 22 is provided with evenly distributed arc grooves, and the arc grooves of the two clamping blocks 22 are symmetrically arranged. The radius of the arc groove provided by the clamping block 22 is the same as the radius of the fixed cylinder 9. By setting the fixing component 2, the plug-in rod 8 on one side of the dustproof net 4 is plugged into the plug-in groove 7, and then the fixed round rod is slid into the interior of the shell through the through groove provided in the shell of the detection device body 1, and at the same time, the clamping block 22 is rotated, thereby driving the rotating shaft 21 to rotate and making the two rotating shafts 21 and the rotating block rotate synchronously through two meshing gears 23, and the fixed cylinder 9 is fixed in the arc grooves of the two clamping blocks 22, and the pawl 26 is tightly clamped with the ratchet 24 to prevent the rotating shaft 21 from rotating in the opposite direction, causing the dustproof net 4 to loosen. When the detection device body 1 is working, the dustproof net 4 has a dustproof effect while dissipating heat.
[0037] A slider 25 is slidably connected to the inside of the outer shell of the detection device body 1, and a pawl 26 is integrally connected to one side of the slider 25. One side of the pawl 26 is clamped with the ratchet 24, and a clamping spring 27 is provided on the other side of the slider 25. One end of the clamping spring 27 is in tight contact with the slider 25, and the other side of the clamping spring 27 is in tight contact with the outer shell of the detection device body 1.
[0038] A dial button 28 is integrally connected to the front of the slider 25, and the dial button 28 is located outside the outer shell of the detection device body 1. The dial button 28 is integrally connected to the slider 25 through a connecting block that is slidably connected to the outer shell of the detection device body 1. By setting the dial button 28, when the dust screen 4 needs to be replaced, the dial button 28 is toggled to make the slider 25 slide and drive the pawl 26 to move, so that the pawl 26 and the ratchet 24 are loosened, and the dust screen 4 is pulled, so that the fixed cylinder 9 slides out from between the two clamping blocks 22, which is convenient for taking out the dust screen 4 for replacement.
[0039] Working principle: Plug the plug-in rod 8 on one side of the dustproof net 4 into the plug-in slot 7, and then slide the fixed cylinder 9 into the interior of the shell through the through slot opened in the shell of the detection device body 1, and at the same time make the clamping block 22 rotate, thereby driving the rotating shaft 21 to rotate and making the two rotating shafts 21 and the rotating block rotate synchronously through the two meshing gears 23, and fix the fixed cylinder 9 in the arc-shaped grooves of the two clamping blocks 22, and the pawl 26 and the ratchet 24 are tightly clamped to prevent the rotating shaft 21 from rotating in the opposite direction, causing the dustproof net 4 to loosen. When the detection device body 1 is working, the dustproof net 4 plays a dust-proof effect while dissipating heat. When the dustproof net 4 needs to be replaced, turn the dial button 28 to make the slider 25 slide and drive the pawl 26 to move, so that the pawl 26 and the ratchet 24 are loosened, and the dustproof net 4 is pulled, so that the fixed cylinder 9 slides out from between the two clamping blocks 22, which is convenient for taking out the dustproof net 4 for replacement.

That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure.
