Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically a low-noise transformer based on a shock-absorbing spring assembly. Background Technology

[0002] In power systems, transformers are key power conversion devices, and the noise generated during their operation has always been a major concern. During the operation of a transformer, factors such as the interaction of internal electromagnetic forces and the operation of the cooling system can generate vibrations and noise, which can not only cause noise pollution to the surrounding environment and interfere with the normal lives of residents, but may also affect the service life and operational stability of the transformer itself.

[0003] Currently, existing transformer vibration reduction and noise reduction technologies mostly employ single vibration reduction structures, such as simple spring or rubber vibration dampers. These methods have limited vibration reduction effects, are difficult to cope with the complex and variable vibration conditions during transformer operation, and lack real-time monitoring and precise control mechanisms. They cannot adjust the vibration reduction system according to the actual operating conditions of the transformer. At the same time, friction between components also generates additional noise, further affecting the noise reduction effect. This makes it difficult to meet the requirements of modern power equipment for low noise and high stability. Therefore, there is an urgent need for a new type of vibration reduction and noise reduction structure to effectively reduce transformer operating noise and improve its operating performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a low-noise transformer based on a shock-absorbing spring assembly.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-noise transformer based on a shock-absorbing spring assembly, including a transformer and a transformer bracket. The transformer bracket is fixed to the bottom end of the transformer. A shock-absorbing connector is threaded to the bottom end of the transformer bracket. A pressure sensor is fixed between the shock-absorbing connector and the transformer bracket. A multi-angle connector is fixed to the bottom end of the shock-absorbing connector. A spring is fixed to the bottom end of the multi-angle connector. A shock-absorbing support is fixed to the bottom end of the spring. An auxiliary shock-absorbing component is provided inside the shock-absorbing support. A transformer mounting base is fixed to the bottom end of the shock-absorbing support.

[0006] Furthermore, a strip-shaped mounting groove is provided at the top of the shock-absorbing connector, the strip-shaped mounting groove is connected to the pressure sensor, and an annular gasket is fixed at the top of the shock-absorbing connector.

[0007] Furthermore, the multi-angle connector includes a spherical connector, which is fixed to the bottom end of the shock-absorbing connector. A pressure plate is rotatably connected to the outer wall of the spherical connector, and the bottom end of the pressure plate is fixedly connected to a spring.

[0008] Furthermore, a spherical groove is provided inside the top of the pressure plate, and the spherical groove is rotatably connected to the spherical connector. A damping pad is provided inside the spherical groove.

[0009] Furthermore, the auxiliary shock absorption component includes an air pump body, which is fixed inside the shock absorption support, and an airbag is fixed to the top of the shock absorption support.

[0010] Furthermore, an inflation tube is fixed to the top of the inflation pump body, and the inflation tube passes through the shock-absorbing support and connects to the airbag.

[0011] Furthermore, the shock-absorbing support has a groove inside, and the edge of the groove fits into the air pump body. The air pump body is fixedly connected to the shock-absorbing support by bolts.

[0012] The beneficial effects of this utility model are:

[0013] Vibration damping effect: The spring and the airbag in the auxiliary vibration damping component work together. The spring uses a high-elasticity alloy material to initially absorb vibration, and the airbag forms elastic support by adjusting the inflation volume through the inflation pump. The two work together to effectively absorb and disperse the vibration energy generated by the transformer operation, greatly improving the vibration damping effect.

[0014] Noise reduction effect: The ring-shaped gasket buffers the pressure between the transformer bracket and the shock-absorbing connector, reducing friction noise. The damping gasket in the multi-angle connector suppresses the relative rotation between the spherical connector and the pressure plate, reducing the noise generated by vibration transmission, thus reducing the operating noise of the transformer from multiple sources.

[0015] Precise control: High-precision strain gauge pressure sensors monitor changes in transformer operating pressure in real time. The control system precisely adjusts the inflation volume of the air pump to each corner airbag based on the pressure data, so that the damping support force at each corner is balanced. This ensures that the four corners can achieve a consistent damping effect under vibrations of different directions and intensities, thus guaranteeing stable operation of the transformer.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] See Figures 1-4 This is a schematic diagram of the structure of this utility model, which is a low-noise transformer based on a shock-absorbing spring assembly. It includes a transformer 1 and a transformer support 2. The transformer support 2 is fixed to the bottom end of the transformer 1. The bottom end of the transformer support 2 is threadedly connected to a shock-absorbing connector 3. A pressure sensor 4 is fixed between the shock-absorbing connector 3 and the transformer support 2. The pressure sensor 4 is a high-precision strain gauge sensor, which has the characteristics of high sensitivity and fast response speed. It can monitor the pressure changes generated during the operation of the transformer in real time, so as to accurately control the shock absorption system.

[0023] The bottom end of the shock-absorbing connector 3 is fixed with a multi-angle connector, the bottom end of which is fixed with a spring 7, and the bottom end of the spring 7 is fixed with a shock-absorbing support 8, which can better absorb and disperse vibration energy for the spring support. The shock-absorbing support 8 is equipped with an auxiliary shock-absorbing component inside, and the bottom end of the shock-absorbing support 8 is fixed with a transformer mounting base 11. The surface of the transformer mounting base 11 has multiple mounting holes to facilitate fixing to the mounting foundation and ensure the stability of the transformer during operation.

[0024] The top of the shock-absorbing connector 3 is provided with a strip-shaped mounting groove, which is connected to the pressure sensor 4 and can fit perfectly with the pressure sensor 4 to ensure the firmness and stability of the sensor installation. The top of the shock-absorbing connector 3 is fixed with an annular gasket, which is made of wear-resistant and corrosion-resistant rubber material, which can effectively buffer the pressure between the transformer bracket 2 and the shock-absorbing connector 3, and reduce friction and noise.

[0025] The multi-angle connector includes a spherical connector 5, which is fixed to the bottom end of the shock-absorbing connector 3. A pressure plate 6 is rotatably connected to the outer wall of the spherical connector 5. The bottom end of the pressure plate 6 is fixedly connected to a spring 7. A spherical groove is provided inside the top end of the pressure plate 6, and the spherical groove is rotatably connected to the spherical connector 5. A damping pad is provided inside the spherical groove. The damping pad has good damping characteristics and can effectively suppress the relative rotation between the spherical connector 5 and the pressure plate 6, reduce vibration transmission, and reduce noise caused by friction.

[0026] The auxiliary shock absorption component includes an air pump body 10, which is fixed inside the shock absorption support 8. The air pump body 10 uses a miniature high-efficiency air pump, which is small in size, light in weight, low in energy consumption and low in noise. It can automatically adjust the inflation volume of the airbag 9 according to the instructions of the control system. The top of the shock absorption support 8 is fixed with an airbag 9, which is made of highly elastic and airtight rubber material. It has good flexibility and pressure resistance and can form an effective elastic support after inflation, further enhancing the shock absorption effect. The top of the air pump body 10 is fixed with an inflation tube, which passes through the shock absorption support 8 and connects to the airbag 9.

[0027] The shock-absorbing support 8 has a groove inside, and the edge of the groove fits into the air pump body 10, which can provide good installation space and fixed support for the air pump body 10. The air pump body 10 is fixedly connected to the shock-absorbing support 8 by bolts. The bolts are made of high-strength stainless steel, which has good corrosion resistance and ensures the firmness and stability of the air pump body 10 installation.

[0028] When using this utility model:

[0029] When installing a low-noise transformer based on a shock-absorbing spring assembly, the transformer is first fixed to the mounting base through multiple mounting holes on the surface of the transformer mounting base 11, providing stable bottom support for the transformer. Next, the transformer 1 is fixed to the transformer bracket 2, and then the shock-absorbing connector 3 is installed at the bottom of the transformer bracket 2 by means of threaded connection. At the same time, the pressure sensor 4 is embedded in the strip-shaped mounting groove at the top of the shock-absorbing connector 3, and the two fit perfectly. The annular gasket is placed between the transformer bracket 2 and the shock-absorbing connector 3 to effectively buffer pressure and reduce friction and noise.

[0030] The spherical connector 5 in the multi-angle connector is fixed to the bottom of the shock-absorbing connector 3. It is rotatably connected to the pressure plate 6 through the spherical groove. The damping pad in the groove suppresses the relative rotation between the two, reducing vibration transmission and noise. The bottom of the pressure plate 6 is connected to the spring 7. The bottom of the spring 7 is connected to the shock-absorbing support 8. The spring 7 uses its own high elasticity alloy material to initially absorb the vibration generated by the operation of the transformer.

[0031] The auxiliary damping components inside the damping support 8 play an important role. The air pump body 10, as a miniature high-efficiency air pump, adjusts the inflation volume of the airbag 9 through the inflation tube according to the control system command. After inflation, it forms an elastic support, which works in conjunction with the spring 7 to further enhance the damping effect. The pressure sensor 4 monitors the pressure changes at each corner during the operation of the transformer in real time. According to the pressure data, the control system precisely adjusts the inflation volume of the air pump body 10 to each corner airbag 9 to make the damping support force at each corner balanced. At the same time, through the synergistic effect of the multi-angle connector, the spring 7 and the damping support 8, it ensures that the four corners can achieve a consistent damping effect when facing vibrations of different directions and intensities, ultimately effectively reducing the operating noise of the transformer and maintaining its stable operation.
