[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5 As shown, a mounting base for a transformer comprises two supporting brackets 1, wherein the bottom surface of the supporting bracket 1 is fixedly connected to two symmetrically arranged fixing plates 2, fixing holes 12 are provided on the surfaces of the fixing plates 2 and the supporting bracket 1, fixing rods 3 are slidably connected in the fixing holes 12, a connecting plate 4 is fixedly connected to the bottom end of the fixing rod 3, a pressure spring 5 is fixedly connected to the bottom surface of the connecting plate 4, a bottom end of the pressure spring 5 is fixedly connected to a bottom plate 6, mounting holes 7 are provided at the four corners of the bottom plate 6, a fixing block 14 is fixedly connected to the top end of the fixing rod 3, two symmetrically arranged balancing components are fixedly connected to the surface of the bottom plate 6, and the connecting plate 4 is located between the two balancing components.

[0023] like Figure 1 As shown, a transformer mounting base in the utility model is similar to the existing transformer base structure, such as a transformer mounting base disclosed in the patent publication number CN220041535U. The main improvement of the utility model is to improve the shock absorption effect of the mounting base. Figures 1 to 5As shown, when a transformer mounting base in the utility model is in use, when the transformer vibrates during operation due to changes in internal electromagnetic force or other reasons, the pressure spring 5 can consume part of the vibration energy during compression and recovery, thereby greatly reducing the impact load caused by the vibration, avoiding the vibration from being directly transmitted to the bottom plate 6 and the ground, thereby effectively reducing the vibration impact on the transformer, protecting the internal components of the transformer, extending its service life, and ensuring the working efficiency and stability of the transformer; the staff can use bolts to fix the bottom plate 6 to the ground using the mounting holes 7.

[0024] By arranging a damping mechanism consisting of a fixing plate 2, a fixing rod 3, a connecting plate 4 and a pressure spring 5 between the supporting bracket 1 and the bottom plate 6, and utilizing the pressure spring 5, the transformer is always kept running in a suitable damping state, effectively avoiding damage caused by long-term resonance or large-amplitude vibration, improving the service life of the transformer, and ensuring the working efficiency and stability of the transformer.

[0025] like Figures 2 to 4 As shown, the balancing assembly includes a fixing frame 8, a connecting rod 10 and a nut 11. The cross section of the fixing frame 8 is an inverted U-shaped setting. The bottom end of the fixing frame 8 is fixedly connected to the bottom plate 6. Two connecting rods 10 are fixedly connected to the bottom surface of the fixing plate 2. A connecting hole 9 corresponding to the position of the connecting rod 10 is opened on the surface of the fixing frame 8. One end of the connecting rod 10 passes through the connecting hole 9 and is threadedly connected with a nut 11.

[0026] Specifically, through the cooperation between the fixing frame 8 and the connecting rod 10, it can be ensured that the pressure spring 5 moves in a straight line during the compression and recovery process without deflection or misalignment, thereby ensuring the stability and durability of the shock-absorbing effect of the pressure spring 5; the balancing component can also help maintain the overall horizontal posture of the mounting base. When the transformer load is uneven or the foundation is uneven, the nut 11 is turned to adjust the protruding length of the connecting rod 10 in the connecting hole 9, and the position of the connecting rod 10 on the fixing frame 8 is adjusted. The base plate 6 can be adapted to different terrain conditions to achieve the best shock-absorbing balance effect, thereby improving the overall working stability and safety of the transformer in various complex environments.

[0027] like Figure 4 As shown, two pressure springs 5 ​​are fixedly connected between the connecting plate 4 and the bottom plate 6, and connecting blocks 13 are fixedly connected to both ends of the pressure springs 5, and the connecting blocks 13 are fixedly connected to the bottom surface of the connecting plate 4 and the surface of the bottom plate 6 respectively.

[0028] Specifically, by providing two pressure springs 5, double-layer shock absorption can be achieved. Compared with a single spring design, the double spring structure can more effectively suppress the spread of vibration and provide a more balanced and lasting shock absorption effect. The design of the double pressure spring 5 is also conducive to improving the redundancy and reliability of the entire mounting base. In the event that one spring may fail due to fatigue, the other spring can still continue to provide the necessary shock absorption support, thereby ensuring that the transformer always operates in a good shock absorption environment during its service life, effectively reducing various potential faults caused by vibration, extending the service life of the transformer and its internal components, and ensuring the stability and safety of the power system.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a protective cover is provided on the outer wall of the pressure spring 5, and the upper and lower sides of the protective cover are fixedly connected to the connecting plate 4 and the bottom plate 6 respectively.

[0030] Specifically, the design of the protective cover can effectively isolate the adverse effects of the external environment on the pressure spring 5, such as dust, moisture, chemicals, etc., and prevent the pressure spring 5 from rusting and corroding, thereby extending the service life of the pressure spring 5 and ensuring that it can maintain a good working condition in various environments.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the protective cover is an accordion cover 15 .

[0032] Specifically, the protective cover adopts an accordion cover 15 design. Since the accordion cover 15 has good flexibility, wear resistance and weather resistance, its unique pleated structure design allows it to be freely folded and unfolded during the expansion and contraction of the pressure spring 5, which can not only ensure the comprehensive wrapping and protection of the pressure spring 5, but also avoid obstruction to the spring movement; the accordion cover 15 is usually made of multiple layers of corrosion-resistant materials, which can effectively prevent moisture, dust and other harmful substances from invading the interior of the pressure spring 5 in harsh environments, and can also resist a certain degree of physical wear and impact, thereby greatly improving the service life of the pressure spring 5 and the stability of the shock absorption effect.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, a magnetic ring 16 is fixedly connected to the bottom side of the accordion cover 15 , and a connecting groove 17 corresponding to the position of the magnetic ring 16 is opened on the surface of the bottom plate 6 .

[0034] Specifically, the adsorption effect between the magnetic ring 16 and the bottom plate 6 can provide a seal for the bottom of the accordion cover 15, and can also facilitate the maintenance of the pressure spring 5 by the staff; the magnetic ring 16 is adsorbed in the connecting groove 17 by magnetic force. This design is convenient and fast, and can achieve a stable connection without the need for additional complex mechanical structures, and is easy to disassemble and maintain.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
