Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides two technical solutions:

[0028] Figures 1 - 6 The first implementation manner is shown: an installation structure of an oil-immersed transformer, including a transformer body 1, wedge-shaped plates 11 are symmetrically installed at the bottom of the transformer body 1, and an installation mechanism is arranged below the transformer body 1. The installation mechanism includes:

[0029] A support assembly 2 is arranged at the bottom of the transformer body 1. The support assembly 2 includes a support plate 21;

[0030] A fixing assembly 3 is arranged on the top of the support plate 21. The fixing assembly 3 includes four fixing blocks 31. The four fixing blocks 31 are evenly distributed into two groups and are symmetrically installed on the top of the support plate 21 from left to right. A rectangular hole 32 is formed on the outer surface of the fixing block 31, and a wedge-shaped block 36 is movably arranged inside the rectangular hole 32;

[0031] A loosening assembly 4 is provided. The number of the loosening assemblies 4 is set to two groups and is symmetrically arranged on the top of the support plate 21 from left to right. The loosening assembly 4 includes a first rotating shaft 41, wheel frames 42 are symmetrically and fixedly installed on the outer wall of the first rotating shaft 41, and rollers 43 are rotatably installed inside the wheel frames 42.

[0032] A plurality of lifting rings 13 are installed on the top of the transformer body 1, and tapered columns 12 are symmetrically installed at the bottom of the wedge-shaped plates 11. The plurality of lifting rings 13 on the top of the transformer body 1 facilitate installation and handling and can flexibly adjust the position. The tapered columns 12 symmetrically installed at the bottom of the wedge-shaped plates 11 can accurately position the installation and enhance the connection stability.

[0033] A tapered hole 22 matching the tapered column 12 is formed on the top of the support assembly 2. Two movable rods 23 are installed at positions close to the left and right sides of the bottom of the support plate 21, and a first arc-shaped fixing frame 24 is installed between the two movable rods 23. A second arc-shaped fixing frame 25 is installed on one side of the first arc-shaped fixing frame 24 through bolts and studs. Anti-slip pads 26 are arranged on the inner sides of the first arc-shaped fixing frame 24 and the second arc-shaped fixing frame 25. The movable rods 23 at the bottom of the support plate 21 are connected to the first arc-shaped fixing frame 24, which is convenient for adjusting the position to adapt to different electric poles. The first arc-shaped fixing frame 24 and the second arc-shaped fixing frame 25 can hold the electric pole, and the bolt and stud connection is convenient for installation and disassembly. The anti-slip pads 26 on the inner side increase the friction with the electric pole and improve the overall stability of the support frame.

[0034] On the outer side surface of the fixed block 31, a first round hole 33 is provided. Inside the first round hole 33, there is a spring 34, and one end of the spring 34 is fixedly connected to the inner side wall of the first round hole 33 facing inwards. The fixing assembly 3 further includes two connecting plates 35, and the two connecting plates 35 are symmetrically arranged left and right and are fixedly connected to the outer side surface of the wedge-shaped block 36. On the inner side surface of the connecting plate 35 facing inwards, second round holes 37 are symmetrically provided. The outer side inner wall of the second round hole 37 is fixedly connected to the other end of the spring 34. The spring 34 can exert a pulling force on the connecting plate 35. When the connecting plate 35 is not subjected to an external force, it always fits against the fixed block 31.

[0035] Figures 1 - 6 The second implementation manner is shown. The main difference from the first implementation manner is that two first rotating shafts 41 are respectively rotatably arranged between the opposite side surfaces of two groups of fixed blocks 31. Near the middle position on the outer wall of the first rotating shaft 41, a connecting plate 44 is fixedly connected, and the connecting plate 44 extends outwards. At the top of the connecting plate 44, a handle 45 is fixedly connected. When it is necessary to disassemble and repair the transformer body 1, the handle 45 can be operated to drive the connecting plate 44 and the first rotating shaft 41 to rotate, driving the roller 43 to squeeze the connecting plate 35, forcing the connecting plate 35 to move outwards, so that the wedge-shaped block 36 is disengaged from the wedge-shaped plate 11, facilitating the disassembly of the transformer body 1 and providing a convenient operation method for the repair work.

[0036] The releasing assembly 4 further includes two second rotating shafts 46. The two second rotating shafts 46 are symmetrically installed left and right on the top of the support plate 21. A baffle 47 is rotatably provided on the outer wall of the second rotating shaft 46. By rotating the baffle 47, the handle 45 can be blocked to prevent the handle 45 from rebounding.

[0037] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] When in use, the support assembly 2 is first installed between two electric poles. Before this, the second arc-shaped fixing frame 25 is not connected to the first arc-shaped fixing frame 24. The first arc-shaped fixing frames 24 on both sides are in contact with the electric poles, and under the action of the overall weight of the support frame, downward pressure is applied to the two first arc-shaped fixing frames 24, forcing the two first arc-shaped fixing frames 24 to fit tightly with the electric poles. Afterwards, the second arc-shaped fixing frame 25 is installed on the first arc-shaped fixing frame 24 by bolts and studs to hold the electric poles, thereby improving the overall stability of the support frame. After that, the lifting ring 13 on the transformer body 1 is fixed to the lifting arm of the crane through a rope, and the transformer body 1 is lifted to a suitable height, and the approximate position of the transformer body 1 is adjusted so that the conical column 12 and the conical hole 22 are roughly aligned, and then the transformer body 1 is lowered. When the transformer body 1 moves downward, the inclined surface on the wedge plate 11 will first contact the inclined surface on the fixing block 31, which is used to ensure the centering of the transformer body 1 in the left and right directions, and facilitate the insertion of the conical column 12 into the conical hole 22. As the transformer body 1 is continuously When the wedge plate 11 descends, the inclined surface on the wedge plate 11 contacts the inclined surface on the wedge block 36 and generates an extrusion force, forcing the wedge block 36 and the connecting plate 35 to move outward. When the wedge plate 11 passes over the wedge block 36, the wedge block 36 is reset under the action of the tension of the spring 34. At this time, the bottom of the wedge block 36 fits the top of the wedge plate 11 and limits it. At the same time, the conical column 12 is also fully inserted into the conical hole 22. At this time, the installation is completed. The installation process is simple and efficient, and there is no need to install multiple sets of bolts. When it needs to be disassembled for maintenance, just press the handle At this time, the first rotating shaft 41 drives the wheel frame 42 to make a circular motion outward, and squeezes the connecting plate 35 through the roller 43, forcing the connecting plate 35 to move outward, thereby causing the wedge block 36 to move outward until the handle 45 is pressed into the groove on the support assembly 2, and then the baffle 47 is moved to block the handle 45 to prevent the handle 45 from rebounding, so as to facilitate the wedge block 36 to detach from the wedge plate 11. When the wedge block 36 moves outward, the wedge plate 11 is limited and fixed again, thereby facilitating the disassembly and maintenance of the transformer body 1.
