Description

Technical Field

[0001] This utility model relates to the system integration of energy storage substations, specifically a lifting support for the transformer inside an energy storage box-type substation. Background Technology

[0002] An energy storage substation system integrates a transformer, high-voltage power distribution equipment, low-voltage switchgear, inverter system, control unit, and a high-protection-level enclosure. The transformer, a device that uses the principle of electromagnetic induction to change AC voltage, primarily consists of a primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. When connecting the transformer to the low-voltage switchgear, size differences can make copper busbar installation inconvenient, preventing direct connection between the transformer and the low-voltage switchgear. Adjusting the transformer's height is necessary, but manually lifting it is too strenuous and difficult to control.

[0003] Based on this, a lifting support for the transformer inside an energy storage transformer substation is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, a lifting support for an internal transformer of an energy storage transformer includes a protective box 1. A box door 11 is rotatably connected to the front of the protective box 1. A low-voltage cabinet 12 is installed on the inner wall of the protective box 1. A horizontal busbar 13 is symmetrically fixedly connected to the outer wall of the low-voltage cabinet 12. A telescopic rod 17 is fixedly connected to the bottom end of the horizontal busbar 13. A transformer 18 is fixedly connected to the bottom end of the telescopic rod 17. A first mounting plate 14, a second mounting plate 15, and a third mounting plate 16 are sequentially fixedly connected to the bottom end of the horizontal busbar 13. A connecting block 19 is symmetrically fixedly connected to the rear end of the first mounting plate 14. A drive mechanism 2 is installed on the outer wall of the first mounting plate 14. A lifting mechanism 3 is installed on the outer wall of the second mounting plate 15.

[0024] In this embodiment, the lifting mechanism 3 is driven by the driving mechanism 2, so that the lifting mechanism 3 drives the transformer 18 to adjust its height. This facilitates the subsequent connection of the copper busbar on the horizontal busbar 13 to the transformer 18. Furthermore, the self-locking action of the driving mechanism 2 can prevent the lifting mechanism 3 from becoming unstable due to the weight of the transformer 18.

[0025] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the drive mechanism 2 includes a turntable 21. A rotating rod 22 is fixedly connected to the top of the turntable 21. The outer wall of the rotating rod 22 is rotatably connected to the inner wall of the connecting block 19. A worm gear 23 is fixedly connected to the outer wall of the rotating rod 22. A worm wheel 24 meshes with the outer wall of the worm gear 23. A first rotating shaft 25 is fixedly connected to the axis of the worm wheel 24. The outer wall of the first rotating shaft 25 is rotatably connected to the inner wall of the first mounting plate 14. Rotating the turntable 21 causes the rotating rod 22 to rotate, which in turn drives the worm gear 23. The worm gear 23 drives the worm wheel 24 to rotate, and the worm wheel 24 drives the first rotating shaft 25 and the first gear 26 to rotate.

[0026] In an optional embodiment, such as Figure 2 and Figure 3 As shown, a first gear 26 is fixedly connected to the outer wall of the first rotating shaft 25, a second gear 27 meshes with the bottom of the first gear 26, a second rotating shaft 28 is fixedly connected to the axis of the second gear 27, the outer wall of the second rotating shaft 28 is rotatably connected to the inner wall of the first mounting plate 14, and a third gear 29 is fixedly connected to the outer wall of the second rotating shaft 28. The first gear 26 is driven to rotate by the first rotating shaft 25, the first gear 26 drives the second gear 27 to rotate, and the second gear 27 drives the second rotating shaft 28 and the third gear 29 to rotate. The third gear 29 drives the fourth gear 31.

[0027] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the lifting mechanism 3 includes a fourth gear 31. The outer wall of the fourth gear 31 is rotatably connected to the outer wall of the second mounting plate 15. The outer wall of the fourth gear 31 meshes with a fifth gear 32. A third rotating shaft 33 is fixedly connected to the axis of the fifth gear 32. The outer wall of the third rotating shaft 33 is rotatably connected to the inner wall of the third mounting plate 16. A sixth gear 34 is symmetrically fixedly connected to the outer wall of the third rotating shaft 33. A toothed plate 35 meshes with the outer wall of the sixth gear 34. The bottom end of the toothed plate 35 is fixedly connected to the top end of the transformer 18. The fourth gear 31 is driven by the driving mechanism 2. The fourth gear 31 drives the fifth gear 32. The fifth gear 32 drives the third rotating shaft 33 and the sixth gear 34 to rotate, so that the sixth gear 34 drives the toothed plate 35 to move upward. This causes the toothed plate 35 to drive the transformer 18 to move upward synchronously, causing the telescopic rod 17 to retract. When the transformer 18 is at a suitable height, the copper busbar on the horizontal busbar 13 can be installed with the transformer 18, thus solving the problem of difficult installation of the copper busbar due to the height difference on site.

[0028] In an optional embodiment, such as Figure 2 and Figure 4 As shown, a guide block 36 is fixedly connected to the outer wall of the toothed plate 35, and a guide rail 37 is in contact with the outer wall of the toothed plate 35. The top end of the guide rail 37 is fixedly connected to the bottom end of the horizontal busbar 13. The outer wall of the guide block 36 is slidably connected to the groove opened on the outer wall of the guide rail 37. When the toothed plate 35 moves upward, it drives the guide block 36 to slide in the groove opened on the outer wall of the guide rail 37. The guide block 36 limits and guides the toothed plate 35, so that the toothed plate 35 will not deviate when it moves, making it more stable.

[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the guide block 36 is T-shaped, and the groove on the outer wall of the guide rail 37 is adapted to the guide block 36. The shape of the guide block 36 prevents it from falling out when it slides in the groove on the outer wall of the guide rail 37, and can limit the sliding direction.

[0030] The above embodiment discloses a lifting support for the transformer inside an energy storage transformer substation. During the installation of the transformer 18, when the height of the transformer 18 needs to be adjusted, the turntable 21 is rotated, causing the turntable 21 to drive the rotating rod 22 to rotate. The rotating rod 22 drives the worm gear 23, which in turn drives the worm wheel 24 to rotate. The worm wheel 24 drives the first rotating shaft 25 and the first gear 26 to rotate. The first gear 26 drives the second gear 27 to rotate, causing the second gear 27 to drive the second rotating shaft 28 and the third gear 29 to rotate. The third gear 29 drives the fourth gear 31, which in turn drives the fifth gear 32. The fifth gear 32 drives the third rotating shaft 33 and the sixth gear 34 to rotate, causing the sixth gear 34 to drive the toothed plate 35 to move upwards. The toothed plate 35 then drives the guide block 36 to move on the outer wall of the guide rail 37. The sliding groove allows the toothed plate 35 to move the transformer 18 upwards synchronously, causing the telescopic rod 17 to retract. Once the transformer 18 is at the appropriate height, the copper busbar on the horizontal busbar 13 can be installed with the transformer 18, thus solving the problem of difficult copper busbar installation due to height differences on site. Moreover, once the height of the transformer 18 is determined, the worm gear 23 and worm wheel 24's self-locking inherent characteristics prevent the transformer 18 from sliding down, making height adjustment easier. In summary, the lifting mechanism 3 is driven by the drive mechanism 2, which in turn drives the transformer 18 to adjust its height, facilitating the subsequent connection of the copper busbar on the horizontal busbar 13 with the transformer 18. Furthermore, the self-locking action of the drive mechanism 2 prevents the lifting mechanism 3 from becoming unstable due to the weight of the transformer 18.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
