[0002] An energy-saving transformer is a transformer specifically designed to improve energy utilization efficiency. It adopts a series of technologies and design optimizations to reduce the losses and energy waste of the transformer itself. Energy-saving transformers usually have higher efficiency, lower no-load losses and load losses, thus playing the role of energy conservation and environmental protection in the power system.

[0003] After retrieval, the Chinese patent document publication number: CN216212710U, discloses a highly energy-saving transformer convenient for maintenance. The staff first opens the connecting mechanism, then rotates the four rectangular covers around the two mounting frames respectively to expose the wiring structure on the upper part of the transformer body. At this time, the staff repairs it, and then rotates the four rectangular covers to cover it again, thus facilitating the staff to repair the wiring at the top of the transformer and improving the work efficiency. And when repairing, the sliding rod on the surface of the sliding connecting frame can be used to open the telescopic storage board, and then it is fixed by the fixing mechanism. After completion, the staff can place the maintenance tools on its surface, which is convenient to take during maintenance.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: an energy-saving transformer convenient for maintenance, including an outer box 1. The outer box 2 is usually made of metal and can face complex outdoor weather conditions. The inner bottom wall of the outer box 1 is fixedly connected with a base 2. The base 2 is the basic part of the transformer and provides support for the transformer. Cross cavities 3 are opened on both the left and right sides inside the base 2. A support rod 4 is slidably connected inside the cross cavity 3. The support rod 4 can slide inside the vertical cavity. A first limiting rod 5 is fixedly connected to the bottom of the support rod 4. A first spring 7 is sleeved outside the first limiting rod 5. A movable ring 8 is slidably connected to the outside of the first limiting rod 5. A limiting rod head 9 is fixedly connected to the bottom of the first limiting rod 5. Movable baffles 12 are slidably connected to both the left and right sides inside the cross cavity 3. A second limiting rod 10 is fixedly connected to the inside of the movable baffle 12. A second spring 11 is sleeved outside the second limiting rod 10. Fixed baffles 13 are slidably connected to the far sides of the outside of the second limiting rod 10. When the limiting rod head 9 driven by the first limiting rod 5 slides to the bottom of the second limiting rod 10, the semicircular design allows the plane of the limiting rod head to be engaged with the second limiting rod 10 to fix the transformer. The top of the support rod 4 is fixedly connected with a transformer 6. The support rod 4 and the transformer 6 are fixedly connected as a whole, and the detachable type is more portable. Fixed blocks 14 are fixedly connected to both the left and right sides inside the outer box 1. A telescopic assembly is arranged on the front side of the fixed block 14. The telescopic assembly is usually electrically driven, improving the portability of use.

[0032] Refer to Figure 2 , one end of the first spring 7 is fixedly connected to the bottom of the support rod 4, and the other end of the first spring 7 is fixedly connected to the top of the movable ring 8. One end of each of the two second springs 11 is fixedly connected to the adjacent sides of the two fixed baffles 13 respectively, and the other end of each of the two second springs 11 is fixedly connected to the far sides of the two movable baffles 12 respectively. The spring is usually made of metal, which can make the compressed spring have better elasticity and ductility.

[0033] Refer to Figure 2 , Figure 3 , Figure 4, the outside of the fixed baffle 13 is fixedly connected to the inside of the cross cavity 3. It is fixed inside the cavity by the fixed baffle 13, so that the spring 10 is limited when compressed, and the compression process is completed. The telescopic assembly includes an electric push rod 15. The bottom end of the electric push rod 15 is rotatably connected to the front side of the fixed block 14. The electric push rod can rotate up and down to meet better telescopic requirements. The driving end of the electric push rod 15 is fixedly connected to a first connecting plate 16. The inside of the first connecting plate 16 is rotatably connected to a second connecting plate 17. The inside of the second connecting plate 17 is rotatably connected to a third connecting plate 18. One of the connecting plates 19 is rotatably connected to the front side of the third connecting plate 18. Through these metal connecting plates, the telescopic assembly is made more stable. One of the two connecting plates 19 is rotatably connected to the adjacent side of the other, and a staircase plate 21 is rotatably connected to the front parts of the left and right sides of the staircase plate 21. The staircase plate 21 is usually made of wood and can be retracted into the outer box 1 when not in use, avoiding corrosion due to long-term exposure and reducing economic costs. Three fixing rods 20 are fixedly connected to the inside of the outer box 1. The outside of one of the fixing rods 20 is rotatably connected to the inside of the two second connecting plates 17, and the outside of the other two fixing rods 20 is fixedly connected to the inside of one of the staircase plates 21. The metal fixing rods provide support for the staircase plate. The top of the adjacent ends of the second limiting rod 10 is in contact with the bottom of the movable ring 8, and the bottom of the adjacent ends of the second limiting rod 10 is in contact with the top of the limiting rod head 9. The outside of the movable ring 8 is slidably connected to the inside of the cross cavity 3, and the outside of the limiting rod head 9 is slidably connected to the inside of the cross cavity 3. When the second limiting rod 10 and the limiting rod head 9 are engaged, the transformer 6 will be fixed, enabling the transformer to work more stably.

[0034] Working principle: First, open the door of the outer box 1, place the transformer 6 on the cross cavity 3 of the base 2 through the support rod 4 at the bottom, apply downward pressure, drive the limit rod one 5, the movable ring 8, and the limit rod head 9 at the bottom of the support rod 4 to slide inside the cross cavity 3. When the limit rod head 9 contacts the horizontal limit rod two 10, it will squeeze the limit rod two 10 to slide inside the fixed baffle, thereby driving the movable baffle 13 on the limit rod two 10 to slide to the left and right sides, applying a force to the spring two 11 sleeved on the limit rod two 10. When the limit rod head 9 slides past the limit rod two 10, the limit rod two 10 is pushed by the reaction force of the spring two 11 to slide towards the middle and get stuck between the limit rod head 9 and the movable ring 8 to complete the fixation. When it needs to be taken out, press the transformer 6 and apply downward pressure again. At this time, since the lower part of the movable ring 8 is limited, it will slide to the bottom of the support rod 4, and then squeeze the limit rod two 10 again through the downward pressure, so that the limit rod two 10 is stuck on the upper part of the movable ring 8. Due to the arc design of the movable ring, it can also slide to contact and fit with the limit rod head 9, so it can slide upward to realize the separation of the support rod 4 and the base 2, achieving the functions of simple installation and disassembly, meeting the maintenance applicability of the transformer 6 with different degrees of damage, and the portability of replacing the transformer.

[0035] Open the door of the outer box 1, turn on the switch of the electric push rod 15. The driving end of the electric push rod 15 drives the connecting plate one 16 to move backward, thereby driving the connecting plate two 17 to rotate around the fixed rod 20. The other end of the connecting plate two 17 rotates downward, and then drives the connecting plate three 18 to push forward, and the connecting plate 19 moves forward. Therefore, the stair plate 21 between the two connecting plates 19 moves forward and downward to unfold. The stair plate 21 at the bottommost supports on the ground, providing convenience for the workers repairing the transformer at a high place, improving the maintenance safety and the applicability of the device.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
