Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In this embodiment, the reinforcement mechanism 2 includes a vertical tube 21, the bottom end of the vertical tube 21 is welded and fixed to the upper surface of the base 1, and the surface of the vertical tube 21 is welded with reinforcement plates 22 on both sides. The interior of the vertical tube 21 is rotatably connected to a threaded rod 23 through a bearing, and the surface of the threaded rod 23 is threadedly connected to a top reinforcement plate 24. The top of the threaded rod 23 is welded with a first bevel gear 25, and the surface of the first bevel gear 25 is provided with a power device 8. The lower surface of the top reinforcement plate 24 is in contact with the upper surface of the transformer body 7.

[0033] The transformer body 7 can be reinforced by the reinforcement plates 22 on both sides to improve its stability during operation. At the same time, the distance between the transformer body 7 and the base 1 can be reduced by the top reinforcement plate 24, thereby ensuring the balance of the transformer body 7 and preventing it from shaking during operation.

[0034] Furthermore, the power device 8 includes a second bevel gear 81, the surface of the second bevel gear 81 is meshed with the surface of the first bevel gear 25, a second rotating rod 82 is welded inside the second bevel gear 81, both ends of the second rotating rod 82 are rotatably connected to the inside of the power box 83, a turbine 84 is welded to the middle of the surface of the second rotating rod 82, a vortex rod 85 is meshed with the surface of the turbine 84, the rear end of the vortex rod 85 passes through the rear of the power box 83 and extends to the outside of the power box 83, and the inner wall of the power box 83 is in contact with the surface of the top reinforcement plate 24.

[0035] By rotating the worm rod 85, the rotation of the turbine 84 can be controlled, thereby rotating the second rotating rod 82, so that the first bevel gear 25 can be controlled to rotate through the second bevel gear 81, thereby realizing the movement of the top reinforcement plate 24 on the surface of the threaded rod 23, which can increase the tension of the transformer body 7 itself.

[0036] Furthermore, the buffer mechanism 3 includes a buffer box 31, two connecting blocks 32 are welded to the bottom wall inside the buffer box 31, a first telescopic rod 33 is welded to the upper surface of the connecting block 32, a cross plate 34 is welded to the top end of the first telescopic rod 33, a first spring 35 is welded to the upper surface of the cross plate 34, a connecting plate 36 is welded to the top end of the first spring 35, the upper surface of the connecting plate 36 is welded and fixed to the lower surface of the transformer body 7, a buffer device 9 is arranged on one side of the connecting block 32, the cross bar 5 is welded to the upper surface of the cross plate 34, and the shock absorbing mechanism 4 is arranged on the upper surface of the cross plate 34 and is located on the left side of the cross bar 5.

[0037] The vibration directly generated by the fan 6 can be weakened by the first spring 35, and then the operation of the buffer device 9 can be controlled by the cross plate 34. At the same time, the vibration force borne by the buffer device 9 can be dispersed by the first telescopic rod 33, thereby reducing the stress degree of the buffer device 9.

[0038] In addition, the buffer device 9 includes a second telescopic rod 91, the right end of the second telescopic rod 91 is welded and fixed to one side of the connecting block 32, a first clamping block 92 is welded to the right side of the surface of the second telescopic rod 91, a second spring 93 is welded to the left side of the first clamping block 92 and is located outside the second telescopic rod 91, a second clamping block 94 is welded to the left end of the second spring 93, and the left end of the second telescopic rod 91 is rotatably connected to a triangular plate 95, the surface of the triangular plate 95 is rotatably connected to the inner wall of the buffer box 31 through a first rotating rod 96, and the surface of the triangular plate 95 is slidably connected to the lower surface of the cross plate 34.

[0039] The rotation of the triangular plate 95 can be controlled by the transverse plate 34 , so that the force transmitted from the triangular plate 95 is consumed by the second telescopic rod 91 and the second spring 93 , so as to reduce the vibration force generated by the fan 6 .

[0040] In addition, the shock absorbing mechanism 4 includes a soft rubber plate 41, the lower surface of the soft rubber plate 41 is fixedly connected to the upper surface of the cross bar 5, and the two sides of the soft rubber plate 41 are slidably connected with vertical rods 42, and the top of the vertical rod 42 is welded with a slide rod 43. The middle part of the surface of the slide rod 43 is sleeved with a first return spring 44, and the first rebound device 10 and the second rebound device 11 are respectively provided at both ends of the first return spring 44. The first rebound device 10 is located on the left side of the first return spring 44, and the second rebound device 11 is located on the right side of the first return spring 44.

[0041] The first return spring 44 can expand the first rebound device 10 and the second rebound device 11 inwardly, and can also be reset by the first return spring 44 to achieve the purpose of continuous shock absorption of the shock absorbing mechanism 4 .

[0042] It is worth noting that the first rebound device 10 includes a movable plate 101, the surface of the movable plate 101 is slidably connected to the surface of the sliding rod 43, two rotating cross frames 102 are welded on the left side of the movable plate 101, a tension spring 103 is welded and fixed between the two rotating cross frames 102, a push plate 104 is welded on the left ends of the two rotating cross frames 102, the inside of the push plate 104 is slidably connected to the surface of the sliding rod 43, two push rods 105 are welded on the left side of the push plate 104, a rebound plate 106 is fixedly connected to the left ends of the two push rods 105, a second reset spring 107 is fixedly connected to the left side of the rebound plate 106, a vertical plate 108 is welded to the left end of the second reset spring 107, a shock-absorbing plate 109 is welded to the upper surface of the rotating cross frame 102, and a dispersion device 12 is arranged on the left side of the vertical plate 108.

[0043] By rotating the cross frame 102 to expand and contract, the push plate 104 and the movable plate 101 can be controlled to move to both sides, so that the applied force is converted to both sides, so that neither the vibration force generated by the fan 6 nor the external force will have an impact on the transformer body 7, and the transformer body 7 can run smoothly, ensuring the stability of the transformer body 7. The rebound plate 106 is made of beryllium bronze.

[0044] It is worth noting that the internal structures of the first rebound device 10 and the second rebound device 11 are the same. The dispersion device 12 includes a first rotating rod 121. The right side of the first rotating rod 121 is rotatably connected to the second rotating rod 122. The right side of the second rotating rod 122 is rotatably connected to the left side of the vertical plate 108. A third return spring 123 is welded to the lower surface of the first rotating rod 121. The bottom end of the third return spring 123 is welded and fixed to the upper surface of the second rotating rod 122. The upper surface of the first rotating rod 121 is welded and fixed to the lower surface of the transformer body 7. The lower surface of the second rotating rod 122 is welded and fixed to the upper surface of the base 1.

[0045] The first rotating rod 121 and the second rotating rod 122 arranged at the top and bottom ends of the third reset spring 123 in the dispersion device 12 can disperse the vibration generated on both sides of the transformer body 7 from the dispersion device 12, thereby increasing the stability of the transformer body 7 and preventing the vibration generated by it from affecting the performance of the transformer product.

[0046] It is worth mentioning that there are two shock absorbing mechanisms 4, and the two shock absorbing mechanisms 4 are symmetrically distributed with the center line of the transformer body 7 as the symmetry axis. The two shock absorbing mechanisms 4 can increase the balance stability of the transformer body 7 and prevent the left and right sides of the transformer body 7 from being on the same horizontal line during operation, thereby affecting the service life and operational reliability of the transformer body 7.

[0047] When the dry-type transformer body bracing structure of the present invention is in use, the vibration of the fan 6 will cause the connecting plate 36 to vibrate up and down, and the movement of the connecting plate 36 will cause the first spring 35 to move up and down, and the first spring 35 will cause the cross plate 34 to move up and down. When the cross plate 34 vibrates, the first rotating rod 96 will rotate inward, thereby causing the second telescopic rod 91 to be telescoped. While the second telescopic rod 91 is telescoped, the second spring 93 can increase the resistance and reduce the telescopic distance of the second telescopic rod 91.

[0048] When the cross plate 34 moves downward, the extension and retraction of the first telescopic rod 33 will also be controlled to disperse the impact force of the cross plate 34, and the cross bar 5 welded on the surface of the cross plate 34 will make the fan 6 suspended, and the vibration generated by the fan 6 will be eliminated by the buffer mechanism 3 and the shock absorbing mechanism 4. The soft rubber plate 41 fixedly connected to the cross bar 5 will push the rotating cross frame 102 upward when vibrating, thereby causing the moving plate 101 and the pushing plate 104 to slide to both sides, and when the moving plate 101 slides inward, the force will be dispersed by the first return spring 44, and the pushing plate 104 will transfer the force to the rebound plate 106 through the push rod 105, so that the rebound plate 106 offsets the force through its own elasticity, and at the same time, the push rod 105 will move inward through the second return spring 107, thereby resetting the rotating cross frame 102.

[0049] Through the rotational connection between the first rotating rod 121 and the second rotating rod 122, the downward force on both sides of the transformer body 7 can be offset by the third reset spring 123 in the dispersion device 12, thereby increasing stability. At the same time, the reinforcement mechanism 2 can increase the firmness of the transformer body 7, thereby increasing its service life.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
