Technical Field
[0001] The utility model relates to the technical field of transformer acoustic fingerprint monitoring, in particular to a vibration isolation bracket for installing a transformer acoustic fingerprint monitoring device. Background Art
[0002] With the progress of society and the development of economy, electricity has become an indispensable part of people's daily life. As an important part of the stable operation of the power system, the safe and stable operation of the transformer itself is crucial. During the operation of the transformer, the internal iron core, winding and other structures will vibrate and generate mechanical waves. The generated vibration and sound signals contain a large amount of equipment status information, that is, acoustic fingerprints, referred to as acoustic patterns for short. Since the vibration signal of the transformer has stronger anti-interference ability than the sound signal, current research on the status monitoring of transformers mostly uses acoustic pattern monitoring devices for research. When the transformer shows abnormal conditions, the acoustic pattern will also change accordingly. Combining artificial intelligence means such as deep learning, the status of the transformer can be effectively judged according to the acoustic pattern information.
[0003] During the operation of the transformer, a bracket is used to fix and install the acoustic pattern monitoring device at the required position. However, during actual monitoring, it is found that the vibration generated by the transformer during operation will be transmitted along the ground to the fixed bracket of the acoustic pattern monitoring device. Affected by the vibration, the fixed bracket resonates with the transformer, resulting in inaccurate monitoring results of the acoustic pattern monitoring device. Currently, the method of suspending the acoustic pattern monitoring device is used to eliminate the influence of resonance, but suspension will cause the acoustic pattern monitoring device to be unstable and does not meet the requirements of the monitoring distance.

[0028] The following describes the specific implementation of the utility model in conjunction with the accompanying drawings and embodiments:
[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which the present utility model can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present utility model without affecting the effects and purposes that can be achieved by the present utility model.
[0030] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present utility model. Changes or adjustments to their relative relationships shall be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.
[0031] like Figures 1 to 7 As shown, it shows a specific implementation of the utility model: the vibration isolation bracket for installing a transformer voiceprint monitoring device disclosed in the utility model includes a first bracket 1, a second bracket 2, a vibration isolation mechanism 3, and a device fixed base 4. The lower end of the first bracket 1 is a conical structure, and its upper end is cylindrical, and the upper end and the lower end are integrally formed. The vibration isolation mechanism 3 is located above the first bracket 1, and the bottom of the vibration isolation mechanism 3 is connected to the top position of the first bracket 1. The second bracket 2 is located above the vibration isolation mechanism 3, and the top of the vibration isolation mechanism 3 is connected to the bottom position of the second bracket 2. The device fixed base 4 is installed on the top of the second bracket 2, and the voiceprint monitoring device 5 is installed above the device fixed base 4 by bolts.
[0032] In the present utility model, Figure 1As shown in the figure, an anti-vibration mechanism 3 is adopted between the first bracket 1 and the second bracket 2 of the voiceprint monitoring device 5 to isolate the vibration generated by the operation of the transformer from being transmitted to the first bracket 1 from the ground, avoiding the resonance phenomenon of the second bracket 2 where the voiceprint monitoring device 5 is installed due to the vibration of the transformer, eliminating the influence of noise on the monitoring results of the voiceprint monitoring device 5, ensuring the accuracy of the monitoring results, thus facilitating the analysis of relevant noise data and ensuring the stable operation of the transformer.
[0033] In the present utility model, as Figure 1 shown, the lower end of the first bracket 1 is a conical structure, which is convenient for inserting the first bracket 1 into the ground beside the transformer for fixation. When the transformer is an oil-immersed transformer, the height of the first bracket 1 is higher than the height of the pebbles below the transformer. At the same time, fixing rods can be installed around the first bracket 1 to fix the first bracket 1 against tipping using the structural principle of triangle stability, so as to ensure that the transformer is stably fixed on the ground and avoid affecting the monitoring results of the voiceprint monitoring device 5.
[0034] The anti-vibration mechanism 3 includes a first anti-vibration pad 31, a wedge-shaped anti-vibration seat 32, a spring anti-vibration component 33, and a second anti-vibration pad 34. The bottom of the first anti-vibration pad 31 is connected to the top of the first bracket 1, the top of the first anti-vibration pad 31 is connected to the wedge-shaped anti-vibration seat 32, the top of the wedge-shaped anti-vibration seat 32 is connected to the spring anti-vibration component 33, the top of the spring anti-vibration component 33 is connected to the second anti-vibration pad 34, and the top of the second anti-vibration pad 34 is connected to the bottom of the second bracket 2.
[0035] In the present utility model, as Figure 2 shown, the anti-vibration mechanism 3 eliminates most of the vibrations from the ground through the first anti-vibration pad 31, eliminates the remaining vibrations through the spring anti-vibration component 33 and the wedge-shaped anti-vibration seat 32, and finally comprehensively isolates the vibration of the first bracket 1 from the ground through the second anti-vibration pad 34, avoiding the vibration of the second bracket 2 installed above the anti-vibration mechanism 3, thereby eliminating the resonance of the second bracket 2 where the voiceprint monitoring device 5 is installed and ensuring the accuracy of the noise collected by the voiceprint monitoring device 5.
[0036] Specifically, the first anti-vibration pad 31 and the second anti-vibration pad 34 have the same structure, both being V-shaped structures. The tip of the V-shaped structure of the first anti-vibration pad 31 is connected to the top of the first bracket 1, and the tip of the V-shaped structure of the second anti-vibration pad 34 is connected to the bottom end of the second bracket 2.
[0037] Specifically, the first anti-vibration pad 31 and the second anti-vibration pad 34 are made of rubber.
[0038] In the present utility model, as Figure 2 、 Figure 3As shown, the V-shaped structure has its V-shaped tip decomposing the vibration transmitted from the ground, which can effectively reduce the impact of vibration.
[0039] Specifically, the wedge-shaped vibration isolation seat 32 includes a wedge-shaped damping block 321 and a wedge-shaped base 322. The exterior of the wedge-shaped base 322 is a cylindrical structure, with a wedge-shaped groove formed thereon. The size of the wedge-shaped groove is adapted to the size of the wedge-shaped damping block 321.
[0040] Specifically, the distance between the cross-section on the wedge-shaped groove and the cross-section of the wedge-shaped damping block 321 is 5 mm, and the wedge-shaped damping block 321 is 5 mm higher than the wedge-shaped base 322.
[0041] Specifically, the wedge-shaped damping block 321 is made of rubber.
[0042] In the present utility model, as Figure 2 shown, the wedge-shaped damping block 321 is located below the wedge-shaped base 322, 5 mm higher than it and having a gap distance therewith. When subjected to vibration, the rubber wedge-shaped damping block 321 undergoes elastic deformation to reduce the impact of vibration.
[0043] Specifically, the spring vibration isolation assembly 33 includes four sets of spring damping vibration reduction mechanisms with the same structure. They are evenly distributed and respectively connected to the top of the wedge-shaped vibration isolation seat 32, including a telescopic cylinder 331, a blocking disk 332, a connecting rod 333, and a telescopic spring 334. The top of the telescopic cylinder 331 is connected below the second vibration isolation pad 34. The diameter of the blocking disk 332 is the same as the inner diameter of the telescopic cylinder 331. The telescopic cylinder 331 contains damping liquid inside, and the blocking disk 332 is located below the damping liquid. A through hole with the same diameter as the connecting rod 333 is formed at the middle position of the blocking disk 332. One end of the connecting rod 333 is connected to the top of the wedge-shaped vibration isolation seat 32, and the other end passes through the blocking disk 332 and contacts the damping liquid. The telescopic spring 334 is sleeved on the connecting rod 333, with one end connected to the top of the wedge-shaped vibration isolation seat 32 and the other end connected to the bottom end of the blocking disk 332.
[0044] In the present utility model, as Figure 2 、 Figure 4 shown, after the vibration isolation by the wedge-shaped vibration isolation seat 32, the telescopic spring 334 of the spring vibration isolation assembly 33 will be compressed or stretched under the influence of vibration, so that the blocking disk 332 moves. Under the action of the damping liquid, it moves slowly, eliminating most of the impact of vibration. Using four sets of spring damping vibration reduction mechanisms with the same structure can comprehensively isolate and eliminate all parts of the vibration transmitted to the first bracket 1, ensuring the reliability of the vibration isolation result.
[0045] Specifically, the interior of the second bracket 2 is a hollow structure, with its top and bottom being solid structures. There is a first cable passing hole 21 opened above the hollow structure at the bottom, and a second cable passing hole 22 opened at the middle position of the top end.
[0046] In the present utility model, as Figure 3 , Figure 7 shown, the design of the first cable passing hole 21 and the second cable passing hole 22 facilitates the placement of the connecting wire of the voiceprint monitoring device 5, enhancing the practicality during use.
[0047] Specifically, the device fixing base 4 includes a fixed groove frame 41 and a rotating groove frame 42. The fixed groove frame 41 is fixed at the top end of the second bracket 2, and is provided with a rotation positioning groove 411 and a fixing hole 412. The rotating groove frame 42 is rotatably connected within the fixed groove frame 41, and is provided with a first fixing hole 421 and a second fixing hole 422. The first fixing hole 421 and the fixing hole 412 are rotatably connected together by a bolt, and the second fixing hole 422 moves within the rotation positioning groove 411 and is fixed by a bolt.
[0048] In the present utility model, as Figure 5 , Figure 6 , Figure 7 shown, by fixedly installing the voiceprint monitoring device 5 above the rotating groove frame 42, the first fixing hole 421 and the fixing hole 412 are rotatably connected together by a bolt to fix the position of the rotating groove frame 42, and the position of the second fixing hole 422 within the rotation positioning groove 411 is adjusted to an appropriate angle and fixed, realizing adjustment at different angles to ensure the stable and effective operation of the voiceprint monitoring device 5.
