Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated transformer substations, in particular to a high-voltage prefabricated transformer substation with a stable transport structure. Background Art

[0002] Prefabricated substation is also called "box-type transformer" or "prefabricated substation". Prefabricated substation realizes electrical connection through cables or busbars. All high and low voltage distribution devices and transformers are conventional standard products. Prefabricated substation has the advantages of small size, small footprint, light weight and low cost. Most of the existing prefabricated substations are installed outdoors and need to be connected for lifting.

[0003] However, the existing substations do not have a buffer structure, so they are prone to shaking during transportation, making the substations unstable during transportation. At the same time, violent shaking will also affect the internal electrical components. Therefore, the utility model proposes a high-voltage prefabricated substation with a stable transportation structure to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes a high-voltage prefabricated substation with a stable transfer structure. The high-voltage prefabricated substation with a stable transfer structure is equipped with a transfer seat and a detachable buffer on the transfer seat. When the substation is transferred, the buffer on the transfer seat can protect the substation body.

The fixed rod is fixedly connected to the outer wall of the assembly seat. A moving ring is slidably installed on the fixed rod. One end of the fixed rod is fixed with a limiting plate. A second spring is fixed between the limiting plate and the moving ring. The second spring is sleeved on the fixed rod. A support rod is provided at the top of the moving ring, and the upper end of the support rod is hinged to the stress plate.

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-5 As shown, this embodiment proposes a high-voltage prefabricated substation with a stable transfer structure, including a substation body 1 and a top plate 2. A transfer seat 3 is provided at the bottom of the substation body 1, and mounting grooves 4 are symmetrically provided on the side walls of the transfer seat 3. Buffers are clamped on the mounting grooves 4, and a top plate 2 is fixed on the top of the substation body 1;

[0022] The buffer member includes a load-bearing plate 5, an assembly seat 6, a first buffer component and a second buffer component. The load-bearing plate 5 is fitted with the side wall of the substation body 1, and the assembly seat 6 is installed on the mounting groove 4. The lower end of the load-bearing plate 5 is connected to the inner wall of the assembly seat 6 through the first buffer member, and the outer wall of the assembly seat 6 is provided with a second buffer component, and the second buffer component is hinged to the upper end of the load-bearing plate 5.

[0023] This device is provided with a transfer seat 3 and a detachable buffer part on the transfer seat 3. When the substation is transferred, the buffer part on the transfer seat 3 can protect the substation body 1, and the shaking generated when the substation body 1 moves can be buffered to reduce its shaking amplitude and ensure stability during transfer. After the transfer is completed, the assembly seat 6 can be removed from the installation groove 4, so as to facilitate the lifting and installation of the substation body 1.

[0024] Both sides of the assembly seat 6 are provided with card slots 7, and the assembly seat 6 is mounted in the installation slot 4 through the card slots 7. By carding the card slots 7 of the assembly seat 6 into the installation slot 4 from top to bottom, the assembly seat 6 can be quickly installed and disassembled more conveniently.

[0025] The first buffer assembly includes a sleeve 8, a pressing plate 9, a first spring 10 and a connecting rod 11. One end of the sleeve 8 is fixedly connected to the inner wall of the assembly seat 6. A pressing plate 9 is slidably installed in the sleeve 8. A first spring 10 is provided between the pressing plate 9 and the inner wall of the sleeve. One side of the pressing plate 9 is fixed with a connecting rod 11. One end of the connecting rod 11 is fixedly connected to the stress plate 5. When the substation body 1 shakes during transportation, the stress plate 5 moves along with the substation body 1, thereby pressing the connecting rod 11 to push the pressing plate 9 to move inwardly of the sleeve 8, thereby compressing the first spring 10 to contract. Through the elastic potential energy of the first spring 10, the shaking amplitude of the substation body 1 is reduced, and the substation body 1 is stabilized by reducing the shaking amplitude, thereby protecting the substation body 1.

[0026] The second buffer assembly includes a fixed rod 12, a second spring 13, a limit plate 14, a moving ring 15 and a support rod 16. The fixed rod 12 is fixedly connected to the outer wall of the assembly seat 6. A moving ring 15 is slidably installed on the fixed rod 12. One end of the fixed rod 12 is fixed with a limit plate 14. A second spring 13 is fixed between the limit plate 14 and the moving ring 15. The second spring 13 is sleeved on the fixed rod 12. A support rod 16 is provided at the top of the moving ring 15. The upper end of the support rod 16 is hinged to the stress plate 5.

[0027] When the substation body 1 shakes during transportation, the stress plate 5 moves along with the substation body 1, thereby pressing the support rod 16 and the support ring to move on the fixed rod 12, and at the same time the second spring 13 contracts. Through the elastic potential energy of the second spring 13 cooperating with the first spring 10, the vibration amplitude of the substation body 1 is greatly reduced, and the stability of the substation body 1 during transportation is greatly increased.

[0028] The stress plate 5 includes a first frame 17, a second frame 18, a third frame 19 and a fixing screw 20. The first frame 17, the second frame 18 and the third frame 19 are all in a U shape. The second frame 18 is arranged in the first frame 17. The third frame 19 is arranged in the second frame 18. Fixing screws 20 are provided at the upper ends of the first frame 17 and the second frame 18.

[0029] By moving up the second frame 18 and the third frame 19 and fixing them respectively through the fixing screws 20, the length of the stress plate 5 can be adjusted, thereby increasing the contact area with the substation body 1 and further enhancing the protection of the substation body 1.

[0030] The length of the second frame 18 is longer than that of the first frame 17, and the length of the third frame 19 is longer than that of the second frame 18.

[0031] A semicircular cavity 21 is provided at the four corners of the top of the top plate 2. A semicircular lifting ring 22 is rotatably installed in the semicircular cavity 21. The semicircular lifting ring 22 is stored in the semicircular cavity 21 to prevent the semicircular lifting ring 22 from being corroded by rainwater. At the same time, the substation body 1 can be conveniently lifted through the semicircular lifting ring 22.

[0032] When the high-voltage prefabricated substation with a stable transport structure is transported, when the substation body 1 shakes during transportation, the force plate 5 moves with the substation body 1, thereby compressing the connecting rod 11 to push the pressure plate 9 to move inwardly of the sleeve 8, thereby compressing the first spring 10 to contract, and at the same time, the force plate 5 compresses the support rod 16 and the support ring to move on the fixed rod 12, compressing the second spring 13 to contract, and through the elastic potential energy of the first spring 10 and the second spring 13, the shaking amplitude of the substation body 1 is slowed down, and the substation body 1 is stabilized by reducing the shaking amplitude of the substation body 1, thereby protecting the substation body 1.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
