Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. Figures 1-3 The present application provides an embodiment: a convenient-to-install dry-type transformer, comprising a first I-shaped steel 1, the first I-shaped steel 1 is preferably made of high-quality carbon structural steel, which has high strength and good toughness, and can provide a stable support foundation for the entire device, the first I-shaped steel 1 is fixedly connected with a first fixed plate 2 at the top, the first I-shaped steel 1 is provided with a voltage transformation device 4 on the side wall, the voltage transformation device 4 is fixedly connected with a limiting column 33 at the top, the voltage transformation device 4 is fixedly connected with a first connecting plate 5 at the top, the first connecting plate 5 is fixedly connected with a second I-shaped steel 3 on the side wall, a hollow groove 18 is formed in the first I-shaped steel 1, a buckle assembly is arranged on the side wall of the voltage transformation device 4, and the buckle assembly is used for convenient installation;

[0028] Specifically, when using a convenient installation type dry-type transformer, its unique installation mechanism plays a key role. First, the operator manually rotates the rotating disc 12, which begins to rotate after being subjected to force. In the rotating process, the first fixed column 15 connected therewith also rotates synchronously. At the same time, the second spring 16 connected to the outer wall of the first fixed column 15 begins to shrink due to the force generated by the rotation of the first fixed column 15. With the shrinkage of the second spring 16, the second fixed column 17 originally wrapped therein is also displaced and gradually separated from the inside of the matching hollow groove 18. Through this series of consecutive mechanical actions, the original fixed restriction is successfully removed, so that the dry-type transformer is no longer restricted by the traditional complex connection method during installation, thereby greatly simplifying the installation process, significantly improving the installation efficiency, and ultimately achieving the ideal effect of quick installation, providing strong support and guarantee for the rapid construction and stable operation of the entire power system.

[0029] Reference Figure 1 , Figure 4 and Figure 5The bottom of the voltage transformation device 4 is provided with a support plate 8, which is made of aluminum alloy, has high strength and light weight, can effectively support the voltage transformation device 4 and is convenient to move and install, the inside of the support plate 8 is rotationally connected with a first rotating column 19, the first rotating column 19 is made of alloy structural steel material and has good comprehensive mechanical properties after being quenched and tempered, meets the rotating connection requirement, the outer wall of the first rotating column 19 is rotationally connected with a first rotating plate 20, one side of the first rotating plate 20 is fixedly connected with a second rotating column 21, the outer wall of the second rotating column 21 is fixedly connected with a second rotating plate 22, the second rotating plate 22 is made of aluminum alloy material, has light weight and is convenient to process, the side wall of the second rotating plate 22 is rotationally connected with a third rotating plate 23, the side wall of the third rotating plate 23 is rotationally connected with a first moving wheel 24, the first moving wheel 24 is made of rubber outer polyurethane material, the rubber provides good shock absorption and grip, and the polyurethane ensures certain strength and wear resistance, the top of the support plate 8 is fixedly connected with a first hollow plate 7, the first hollow plate 7 is made of polyvinyl chloride engineering plastic material, has good insulation and certain structural strength, the inner wall of the first hollow plate 7 is fixedly connected with a second connecting plate 29, the side wall of the second connecting plate 29 is rotationally connected with a third connecting plate 30, the side wall of the first hollow plate 7 is fixedly connected with a second fixed plate 25, the top of the third connecting plate 30 is fixedly connected with a hydraulic cylinder 26, the top of the hydraulic cylinder 26 is fixedly connected with a second moving plate 31, the second moving plate 31 is made of aluminum alloy material, the side wall of the second moving plate 31 is rotationally connected with a first moving plate 27, the top of the first moving plate 27 is fixedly connected with a handle 6, the top of the third connecting plate 30 is provided with a third spring 28, one end of the third spring 28 is fixedly connected to the top of the third connecting plate 30, the other end of the third spring 28 is fixedly connected to the bottom of the first moving plate 27, and the output end of the hydraulic cylinder 26 is fixedly connected with a second moving wheel 32.

[0030] Specifically, when operating the installation-convenient dry-type transformer related device to realize the quick moving function, first, the handle 6 needs to be manually pulled, and after the handle 6 is stressed, it starts to rotate around a specific axis. The power generated by the rotation is transmitted to the first moving plate 27 at the bottom through the mechanical structure, driving the first moving plate 27 to rotate synchronously. In the rotating process of the first moving plate 27, the third spring 28 connected thereto starts to contract due to the pulling force and other forces, and the elastic potential energy of the spring is gradually accumulated. At the same time, the rotation of the first moving plate 27 also produces a pressing action on the hydraulic oil, so that the hydraulic oil is accurately injected into the hydraulic cylinder 26. With the injection of the hydraulic oil, the pressure inside the hydraulic cylinder 26 changes, and the output end drives the second moving wheel 32 to move up and down according to the pressure change law. When the second moving wheel 32 moves up and down, there is a specific connection and transmission relationship between it and the first rotating column 19, which drives the first rotating column 19 to rotate, and then promotes the first rotating plate 20 to rotate around the corresponding axis point. The rotation of the first rotating plate 20 also transmits power to the second rotating plate 22 at the bottom, so that the second rotating plate 22 moves with it. Finally, through the third rotating plate 23, the first moving wheel 24 is driven to move up and down. Through this series of complex and orderly mechanical transmission and linkage process, the height adjustment and position transformation of the entire device are realized, and the quick moving effect is successfully achieved, greatly improving the mobility and adaptability of the dry-type transformer in different installation scenes, and laying a solid foundation for efficient and convenient installation operation.

[0031] Referring to Figure 2 The shock absorption assembly includes a hollow column 9, which can be made of high-strength aluminum alloy material. It has the advantages of light weight, high strength, and good corrosion resistance, etc. It can reduce the overall weight while ensuring the structural strength. The outer wall of the hollow column 9 is fixedly connected inside the first fixed plate 2. The first spring 10 is arranged inside the hollow column 9. One end of the first spring 10 is fixedly connected inside the hollow column 9, and the other end of the first spring 10 is fixedly connected to the side wall of the top head 11. The top head 11 can be made of polyurethane rubber material. Polyurethane rubber has high strength, wear resistance and good elastic buffering performance.

[0032] Specifically, when installing the installation-convenient dry-type transformer, the transformer device 4 is first pulled steadily to gradually abut against the side wall of the limiting column 33, and in this process, the limiting column 33 effectively limits the lateral displacement of the transformer device 4 due to its stable structure and specific position, thereby accurately achieving the key effect of limiting the transformer device 4 and ensuring the positional accuracy and stability of the transformer device 4 in the installation plane. Then, the first spring 10 inside the hollow column 9 is used to further optimize the installation process. When the transformer device 4 continuously moves in the predetermined direction, the top head 11 of the side wall will first contact the first spring 10 and generate an interaction force. As the transformer device 4 continuously advances, the pressure exerted by the top head 11 on the first spring 10 gradually increases, causing the first spring 10 to shrink under stress. This shrinkage can cleverly absorb and buffer the impact force and excess kinetic energy generated by the transformer device 4 during movement, effectively preventing the transformer device 4 from being damaged due to collision or sudden stop, successfully achieving the effect of relieving the transformer device 4 and providing reliable protection for the safe and stable installation of the transformer device 4, greatly improving the stability and reliability of the entire dry-type transformer installation process.

[0033] Working principle: when using an installation-convenient dry-type transformer, first rotate the rotating disc 12, and the force of the rotating disc 12 drives the first fixed column 15 to rotate. The first fixed column 15 drives the second spring 16 on the outer wall to shrink while rotating, and then the shrinkage of the second spring 16 drives the second fixed column 17 inside to disengage from the inside of the hollow groove 18, achieving the effect of quick installation. When installing, pull the transformer device 4 to abut against the side wall of the limiting column 33, achieving the effect of limiting the transformer device 4. Then, the first spring 10 inside the hollow column 9 is used, and when the transformer device 4 moves, the top head 11 of the side wall is pressed against the first spring 10 on the side wall, achieving the effect of relieving the transformer device 4. Next, pull the handle 6, and the rotation of the handle 6 drives the first moving plate 27 at the bottom to rotate. The rotation of the first moving plate 27 drives the third spring 28 at the bottom to shrink. In addition, the rotation of the first moving plate 27 injects hydraulic oil into the inside of the hydraulic cylinder 26. Then, the output end of the hydraulic cylinder 26 drives the second moving wheel 32 to move up and down, and when the second moving wheel 32 moves up and down, it drives the first rotating plate 20 to rotate through the first rotating column 19. The rotation of the first rotating plate 20 drives the second rotating plate 22 at the bottom to rotate, causing the third rotating plate 23 to drive the first moving wheel 24 to move up and down, achieving the effect of quick movement.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
