[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A transformer for easy oil replacement includes a housing 1, a bracket 2, a cooling pipe 3, a terminal block 4, an oil conservator 5, and an oil filling hole 6. The surface of the oil conservator 5 is fixedly connected to a mounting pipe 7, a threaded pipe 16, and a mounting block 20. A ring plate 8 is mounted on the surface of the mounting pipe 7. A movable ring 9 is slidably connected to the surface of the mounting pipe 7. A fixing block 10 is fixedly connected to the surface of the movable ring 9. A movable rod 11 is movably connected to the surface of the movable ring 9. A rotating hole 12 is formed on the surface of the fixing block 10. A rotating block 13 is fixedly connected to the surface of the movable rod 11. Rubber pads 14 are fixedly connected to the surfaces of the movable rod 11 and the movable ring 9. A support spring 15 is sleeved on the surface of the mounting pipe 7. The surface of the threaded tube 16 is fitted with a mounting cover 17, and a rope 18 is movably connected to the surface of the mounting cover 17. The surface of the rope 18 has a through hole 19. The surface of the mounting tube 7 has a screw hole 21. The surface of the ring plate 8 has an insertion hole 22 and a groove 23. A screw 24 is inserted and connected to the surface of the insertion hole 22. The housing 1, bracket 2, heat dissipation pipe 3, terminal block 4, oil tank 5, and oil filling hole 6 constitute the main body of the transformer. The transformer oil is injected into the oil tank 5 through the oil filling hole 6 and then enters the housing 1. When changing the transformer oil, it needs to be drained through the drain hole on the housing 1, and the replacement oil is poured in through the oil filling hole 6 after the transformer oil is drained.

[0025] Furthermore, the inner diameter of the mounting pipe 7 is the same as the diameter of the oil injection hole 6, the inner diameter of the ring plate 8 is the same as the inner diameter of the mounting pipe 7, the inner diameter of the movable ring 9 is the same as the outer diameter of the mounting pipe 7, and the outer diameter of the movable ring 9 is smaller than the outer diameter of the ring plate 8. Two sets of fixed blocks 10 and rotating blocks 13 are provided. The diameter of the oil injection hole 6, the inner diameter of the mounting pipe 7, and the inner diameter of the ring plate 8 are the same, which makes it easier for transformer oil to enter the oil tank 5. Under the action of the ring plate 8, the movable ring 9 can be limited along the direction of the mounting pipe 7, and the movable rod 11 can be rotated and limited. The movable rod 11, the rubber pad 14 and the mounting pipe 7 can be connected through the movable ring 9, and the unfolding and retraction of the rubber pad 14 can be made more convenient.

[0026] Furthermore, two sets of fixed blocks 10 and rotating blocks 13 are installed on both sides of the movable rod 11. The two sides of the movable rod 11 are attached to the surface of the fixed blocks 10. The diameter of the rotating hole 12 is the same as the diameter of the rotating block 13. The rotating block 13 is rotatably connected to the surface of the rotating hole 12. The rubber pad 14 is abutted against the surface of the ring plate 8. With the connection of the rotating hole 12 and the rotating block 13, the movable rod 11 and the movable ring 9 can be connected, and the movable rod 11 can rotate around the rotating block 13. The movable rod 11 is provided with four sets and installed on the four sides of the movable ring 9 and the rubber pad 14. The rubber pad 14 has a certain elasticity and can play a role in preventing oil immersion.

[0027] Furthermore, one end of the support spring 15 abuts against the surface of the oil conservator 5, and the other end of the support spring 15 abuts against the surface of the movable rod 11. The inner surface of the mounting cover 17 abuts against the surfaces of the ring plate 8 and the rubber pad 14, and the outer surface of the mounting cover 17 is threadedly connected to the inner surface of the threaded tube 16. The support spring 15 can apply a supporting force to the surface of the movable rod 11, so that the movable rod 11 always tends to rotate towards the ring plate 8, and can make the rubber pad 14 and the ring plate 8 abut against each other, so that when the transformer oil is poured in, it will not leak along the gap between the rubber pad 14 and the ring plate 8. Under the action of the mounting cover 17, the inner side of the ring plate 8 can be covered, thereby sealing the oil filling hole 6. The mounting cover 17 can also limit the position of the stored rubber pad 14.

[0028] Furthermore, one end of the rope 18 is installed on the surface of the oil reservoir 5, and the other end of the rope 18 is installed on the surface of the mounting cover 17. The rope 18 is rotatably connected to the surface of the mounting block 20 through the through hole 19. The rope 18 can connect the oil reservoir 5 and the mounting cover 17 to prevent the mounting cover 17 from being placed randomly after being removed, which would make it difficult to find.

[0029] Furthermore, two sets of through holes 19 and mounting blocks 20 are provided. The two sets of through holes 19 are opened at both ends of the rope 18. One set of mounting blocks 20 is fixedly connected to the surface of the oil tank 5, and the other set of mounting blocks 20 is fixedly connected to the surface of the mounting cover 17. Four sets of screw holes 21, insertion holes 22 and grooves 23 are provided. The mounting blocks 20 can be installed through the through holes 19. The cross-section of the mounting block 20 is "T" shaped and consists of two parts. One part has the same diameter as the diameter of the through hole 19, while the other part has a larger diameter than the diameter of the through hole 19 and fits against the surface of the rope 18.

[0030] Furthermore, four sets of screw holes 21 are provided at the four ends of the mounting tube 7, and four sets of insertion holes 22 and grooves 23 are provided at the four ends of the ring plate 8. The diameter of the groove 23 is larger than the diameter of the insertion hole 22. One end of the screw 24 is threaded to the surface of the screw hole 21, and the other end of the screw 24 is abutted to the surface of the groove 23. Under the action of the screw hole 21, insertion hole 22 and groove 23, the screw 24 can be installed, and under the connection of the screw 24 and the screw hole 21, the ring plate 8 can be disassembled and assembled.

[0031] Working principle: When changing transformer oil, first drain the oil from the drain port, then rotate the mounting cover 17 so that it moves inside the threaded tube 16 through the thread, and drive the mounting block 20 connected to it to rotate in the through hole 19. After the mounting cover 17 is removed, it is connected to the oil conservator 5 through the rope 18. At this time, the movable rod 11 rotates towards the ring plate 8 with the rotating block 13 as the center under the supporting force of the support spring 15, so as to drive the rubber pad 14 to open towards the ring plate 8. The movable ring 9 slides on the mounting tube 7, and the rotating block 13 rotates in the rotating hole 12. When the movable rod 11 and the rubber pad 14 are in the unfolded state, the four sets of movable rods 11 stop moving after forming a certain angle, and the rubber pad 14 is back against the surface of the ring plate 8. Then the operator can pour the transformer oil into the inside of the ring plate 8 and the mounting tube 7 and enter the oil conservator 5 through the oil filling hole 6 to realize the replenishment and replacement of transformer oil.

[0032] When the rubber pad 14 ages and becomes damaged after long-term use, first use a Phillips screwdriver to turn the screw 24 so that it moves through the thread in the screw hole 21 and cancels the engagement with the groove 23. Then remove the screw 24 to cancel the insertion effect with the insertion hole 22. At this time, remove the ring plate 8 from the surface of the mounting tube 7. After the movable rod 11 and the rubber pad 14 lose their limit, they should also be removed from the mounting tube 7 and replaced.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
