Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction devices, in particular to a transformer noise reduction device. Background Art

[0002] In recent years, with the continuous improvement of people's living standards, the electricity consumption of residents has increased rapidly, and the number of power transformers in residential areas has increased year by year. Power transformers are a kind of infrastructure in the power system. Due to the limitations of their working principles, transformers will generate certain noise during operation, which will seriously affect the daily life of residents around the transformers.

[0003] After searching, Chinese patent announcement number: CN216353747U discloses a transformer noise reduction device, including a box body, a box cover is provided on the upper sliding sleeve of the box body, and a group of compression rubber springs are symmetrically provided on both sides of the box body. The utility model provides a compression rubber spring and a flexible spiral compression spring as the main shock-absorbing and noise-reducing components, and provides a rigid spiral compression spring as a supplementary shock-absorbing and noise-reducing component when external vibration occurs, so that the noise reduction performance of the device is better. Through the setting of the bushing spring, while playing the role of shock-absorbing and noise-reducing, the box body and the box cover are prevented from being deflected, causing the flexible spiral compression spring to bend and be damaged. With the setting of the sliding frame, the slider and the slide groove, dust and rain are not easy to enter the device to corrode the internal components, so that the noise reduction device is not easy to be damaged, can have a long service life, and does not need frequent maintenance and replacement of parts. The above device does not have a clear noise reduction mechanism. If the noise generated by the transformer is not reduced, the noise in the environment will continue to exist, which will cause interference and discomfort to the surrounding environment or personnel. There is no shock-absorbing mechanism, so the vibration and impact generated during the operation of the transformer will cause damage to the equipment structure, causing these vibrations to be directly transmitted to the supporting structure around the equipment, increasing the stress and fatigue of the structure, and damaging or shortening its life. Therefore, a transformer noise reduction device is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a transformer noise reduction device, which aims to improve the existing technology that the noise reduction mechanism can effectively reduce the noise level generated by the transformer, and by reducing the noise level, it helps to improve the impact of the transformer on the surrounding environment, and through the shock-absorbing mechanism, it can effectively slow down or absorb the vibration and impact caused by the operation of the transformer, prevent these vibrations from being transmitted to the surrounding structures and foundations through the equipment, and reduce the problems of equipment fatigue and damage.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a transformer noise reduction device, comprising a connecting seat and a base, a shock-absorbing component is arranged at the lower part of the connecting seat, a pulling component is arranged at the lower part of the connecting seat, an inner sound insulation box is fixedly connected to the top of the connecting seat, an outer sound insulation box is fixedly connected to the top of the connecting seat, a sound insulation door is slidably connected to one side of the outer sound insulation box, a handle is fixedly connected to the top of the sound insulation door, sound insulation cotton is fixedly connected to the inside of the inner sound insulation box, a sound insulation board is fixedly connected to the inside of the inner sound insulation box, and a transformer is fixedly connected to the top of the connecting seat.

[0006] Furthermore, the shock absorbing assembly includes a spring 1, and the spring 1 is fixedly connected to the bottom of the connecting seat, and a movable rod is slidably connected to the inner side of the spring 1.

[0007] Furthermore, the pulling assembly includes a fixed block, which is fixedly connected to the bottom of the connecting seat, a pull rod is slidably connected to the opposite side of the fixed block, a moving block is slidably connected to the opposite side of the pull rod, a spring 2 is fixedly connected to the opposite side of the moving block, and a sliding rod is slidably connected to the inner side of the moving block.

[0008] Furthermore, a slide groove is provided on one side of the external sound insulation box and the connecting seat.

[0009] Furthermore, the bottom of the movable rod is fixedly connected with a base.

[0010] Furthermore, an air outlet pipe is fixedly connected to one side of the external sound insulation box, and a second filter is fixedly connected to one side of the air outlet pipe.

[0011] Furthermore, an air inlet pipe is fixedly connected to one side of the external sound insulation box, a filter screen is fixedly connected to one end of the air inlet pipe, and a protective plate is fixedly connected to one end of the air inlet pipe.

[0012] Furthermore, one end of the air inlet pipe is fixedly connected to a fan.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the inner soundproof box, the outer soundproof box and the soundproof door form a noise reduction mechanism. The inner soundproof box and the outer soundproof box are provided with the same soundproof board and soundproof cotton. The soundproof board can effectively prevent the propagation of sound. When the sound wave reaches the soundproof board, its energy is partially reflected and partially absorbed. The soundproof cotton can reduce the reflection of the sound wave, reduce the noise level, improve the acoustic environment, reduce echo and resonance, and the soundproof door can effectively prevent the sound from passing through the door to the environment to avoid noise interference. Through the above, the noise level generated by the transformer can be effectively reduced. By reducing the noise level, it is helpful to improve the impact of the transformer on the surrounding environment.

[0015] 2. In the utility model, the shock absorbing assembly and the pulling assembly constitute a shock absorbing mechanism, which causes the spring 1 to be pressed down by the structure on the connecting seat through vibration, so that the spring 1 performs the first shock absorption, and the movable rod also descends to ensure that the spring 1 will not be distorted. The downward pressure generated at this time causes the multiple fixed blocks to pull the multiple pull rods to both sides, and the multiple moving blocks are pulled to both sides through the multiple pull rods. The pulled multiple moving blocks cause the two connected springs 2 to be pulled on the sliding rod so that the springs 2 are stretched, thereby performing secondary shock absorption through the expansion and contraction force of the springs 2. Through the above, it is achieved that the vibration and impact caused by the operation of the transformer can be effectively reduced or absorbed, and these vibrations can be prevented from being transmitted to the surrounding structures and foundations through the equipment, thereby reducing equipment fatigue and damage.

The sound insulation board 9 can effectively prevent the propagation of sound. When the sound wave reaches the sound insulation board 9, its energy is partially reflected and partially absorbed. The sound insulation cotton 8 can reduce the reflection of the sound wave, reduce the noise level, improve the acoustic environment, reduce echo and resonance, and the sound insulation door 1 can effectively prevent the sound from passing through the door to the environment to avoid noise interference. Pulling the handle 2 can lift the sound insulation door 1 on the slide 3.
