[0014] Beneficial effects

[0015] This utility model provides an installation structure for oil-immersed transformers. Compared with the prior art, it has the following advantages:

[0016] Firstly, this utility model uses a rotating bidirectional screw to retract two sets of limiting brackets along the sliding groove, thereby clamping the support block on both sides. This eliminates the need for complex fixing tools when installing oil-immersed transformers, simplifying the installation process, improving installation efficiency, preventing displacement of the transformer body due to vibration or external force, and thus improving installation stability. It can also adapt to the installation needs of oil-immersed transformer bodies of different models and sizes, improving the versatility and flexibility of the installation structure. Then, the clamping block retracts along the sliding groove inside the limiting bracket, thereby clamping the front and rear side walls of the support block, enhancing the stability of the oil-immersed transformer on the mounting base, and further reducing displacement caused by vibration or external force.

[0017] Secondly, this invention is used when the limiting bracket approaches the support block on the body of the oil-immersed transformer. The locking block is compressed on the fixed bracket by the spring and the telescopic sleeve. Then, when the limiting bracket is clamped against the support block, the locking block is released, allowing it to engage with the locking block on the side wall of the support block. This ensures a further locking effect after clamping and installing the transformer, providing a reliable locking force, enhancing the stability of the clamping and installation, reducing the risk of displacement or loosening caused by vibration, external force or other factors, and preventing potential safety accidents caused by insecure installation.

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution: an installation structure for an oil-immersed transformer, including a mounting base 1, on which an installation mechanism for the transformer equipment is provided, the installation mechanism including:

[0027] The clamping assembly includes a slide groove 3 opened on the upper surface of the mounting base 1. A limiting bracket 302 connected by a threaded assembly is provided inside the slide groove 3. A slide groove 4 is opened inside the limiting bracket 302. A clamping block 401 connected by a pushing assembly is provided inside the slide groove 4.

[0028] The locking assembly includes an oil-immersed transformer body 2 mounted on a mounting base 1, a support block 201 fixed to the lower end of the oil-immersed transformer body 2, a locking block 202 fixed to the side wall of the support block 201, a fixing bracket 6 fixed on a limiting bracket 302, and a connecting block 602 connected to the inner wall of the fixing bracket 6 via an elastic component. The connecting block 602 and the locking block 202 are engaged.

[0029] In a preferred embodiment, the threaded assembly includes a bidirectional screw 301 rotatably connected inside the slide groove 3, and a lower protrusion of the limiting bracket 302 slidably connected inside the slide groove 3. The lower protrusion of the limiting bracket 302 is threadedly connected to the bidirectional screw 301. When the oil-immersed transformer body 2 is placed on the mounting base 1 via the support block 201, rotating the bidirectional screw 301 causes the two sets of limiting brackets 302 to retract along the slide groove 3, thereby limiting and clamping the support block 201. This eliminates the need for complex fixing tools when installing the oil-immersed transformer body 2, simplifying the installation process, improving installation efficiency, preventing displacement of the transformer body due to vibration or external force, thus improving installation stability, and adapting to the installation requirements of oil-immersed transformer bodies 2 of different models and sizes, thereby improving the versatility and flexibility of the installation structure.

[0030] In a preferred embodiment, the jacking assembly includes an electric push rod 5 fixed to the side wall of the limiting bracket 302. A push block 501 is fixed to the telescopic end of the electric push rod 5. Movable rods 502 are provided on both sides of the push block 501 and are rotatably connected by a rotating shaft. A clamping block 401 is located inside the sliding groove 4. One end of the clamping block 401 is rotatably connected to the other end of the movable rod 502 through a rotating shaft. When the limiting bracket 302 is attached to both sides of the support block 201 to install the transformer, the electric push rod 5 extends and retracts the push block 501. The movable rod 502 rotates at both ends through the rotating shaft with the push block 501 and one end of the clamping block 401, causing the angle of the movable rod 502 to change. This causes the clamping block 401 to retract along the sliding groove 4 inside the limiting bracket 302, thereby clamping and installing the front and rear side walls of the support block 201. This enhances the stability of the oil-immersed transformer on the mounting base 1 and further reduces displacement caused by vibration or external force.

[0031] In a preferred embodiment, the elastic component includes a spring 601 fixed to the inner wall of the fixed bracket 6, a locking block 602 fixedly connected to the other end of the spring 601, and a telescopic sleeve 7 provided on the inner ring of the spring 601. The two ends of the telescopic sleeve 7 are fixedly connected to the locking block 602 and the fixed bracket 6, respectively. Before the limiting bracket 302 approaches the support block 201 on the oil-immersed transformer body 2, the locking block 602 is compressed on the fixed bracket 6 by the spring 601 and the telescopic sleeve 7. Then, when the limiting bracket 302 is clamped against the support block 201, the locking block 602 is released, and the locking block 602 engages with the locking block 202 on the side wall of the support block 201. This ensures a further locking effect after clamping and installing the transformer, provides a reliable locking force, enhances the stability of the clamping and installation, reduces displacement caused by vibration, external force or other factors, and prevents potential safety accidents caused by insecure installation.

[0032] In a preferred embodiment, a guide rod 801 is fixed to the side wall of the locking block 602. A pull rod 8 is fixed to one side wall of the guide rod 801 and the pull rod 8 is slidably connected to the fixed bracket 6. A connecting rod 802 is fixed to the other side wall of the guide rod 801. A positioning block 803 is fixed to one side wall of the limiting bracket 302 and the positioning block 803. The connecting rod 802 is slidably connected to the positioning block 803. When the spring 601 is compressed, the guide rod 801 is pulled by the pull rod 8, so that the locking block 602, which is fixedly connected to one end of the guide rod 801, is compressed along the spring 601. The guide rod 801 and the connecting rod 802 are fixedly connected. When pulled, the connecting rod 802 slides synchronously along the positioning block 803 to engage the locking member on the other side.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, firstly, when the oil-immersed transformer body 2 is placed on the mounting base 1 via the support block 201, the bidirectional screw 301 is rotated to cause the two sets of limiting brackets 302 to retract along the sliding groove 3, thereby limiting and clamping the support block 201. This simplifies the installation process by eliminating the need for complex fixing tools. Then, when the limiting brackets 302 are attached to both sides of the support block 201 to install the transformer, the electric push rod 5 extends and retracts the push block 501. The movable rod 502 rotates at both ends via the rotating shaft with one end of the push block 501 and the clamping block 401, causing the angle of the movable rod 502 to change. This causes the clamping block 401 to retract along the sliding groove 4 inside the limiting bracket 302, thereby clamping and installing the front and rear side walls of the support block 201, thus enhancing the stability of the oil-immersed transformer on the mounting base 1.

[0035] Pulling the guide rod 801 by the pull rod 8, before the limiting bracket 302 approaches the support block 201 on the oil-immersed transformer body 2, the locking block 602 is compressed on the fixed bracket 6 by the spring 601 and the telescopic sleeve 7. Then, when the limiting bracket 302 is clamped to the support block 201, the locking block 602 is released, so that the locking block 602 engages with the locking block 202 on the side wall of the support block 201, ensuring a further locking effect after clamping and installing the transformer, providing a reliable locking force, and enhancing the stability of the clamping and installation.
