Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a transformer oil tank structure. Background Technology

[0002] In the field of power equipment, transformers are an important component, and the design and performance of their oil tank structure are crucial. In the current transformer oil tank structure, the transformer is generally embedded inside the oil tank for fixation. Most fixation methods are through bolt tightening. This traditional installation method can, to a certain extent, achieve the connection between the transformer and the oil tank and ensure the stability of the transformer during operation.

[0003] In existing technologies, the lack of an effective connection limiting structure during installation makes it difficult to accurately align the mounting holes on the transformer top plate with the screw holes on the oil tank. This not only increases the difficulty and time cost of installation and reduces installation efficiency, but also, when bolts are tightened due to inaccurate alignment, uneven bolt stress may occur, affecting the firmness of the connection and posing a safety hazard during transformer operation. Furthermore, repeatedly adjusting the positions of the mounting holes and screw holes may damage them, further reducing the service life and reliability of the equipment. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a transformer tank structure that improves installation efficiency and prevents oil leakage. This solves the problems of difficulty in aligning the mounting holes on the top plate with the screw holes in the tank, unstable connection, easy oil leakage, and impact on equipment lifespan and reliability during the installation of traditional transformer tank structures.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a transformer tank structure, wherein a transformer top plate is fixedly installed on the top of the tank body by bolts, a pressing frame is fixedly installed on the bottom of the transformer top plate, a sealing groove is provided on the bottom of the transformer body, a transformer body is fixedly installed on the bottom of the transformer top plate, a snap-fit ​​groove is provided on the outer side of the transformer body, two support bases are fixedly installed on the bottom of the transformer body, a T-shaped sliding groove is provided on the inner side of the tank body, a limit rod is fixedly installed on the inner bottom surface of the T-shaped sliding groove, four connection limit components for improving installation efficiency are symmetrically arranged inside the tank body, the T-shaped sliding groove is used in conjunction with the connection limit components, a sealing component is provided inside the tank body, and the pressing frame is used in conjunction with the sealing component.

[0007] As a preferred technical solution of this utility model, the connecting limiting component further includes a connecting base. The connecting base is movably installed inside the trapezoidal mounting groove via a round rod. An L-shaped support plate is fixedly installed at one end of the connecting base. A semi-circular protrusion is fixedly installed on one side of the L-shaped support plate. The semi-circular protrusion is used in conjunction with a snap-fit ​​groove. A second return spring is fixedly installed on one side of the inclined surface of the trapezoidal mounting groove. The other end of the second return spring is fixedly installed on the side of the L-shaped support plate near the connecting base.

[0008] As a preferred embodiment of the present invention, the sealing assembly includes a rectangular groove, a rectangular frame plate is movably installed inside the rectangular groove, a sealing gasket is fixedly installed on the top of the rectangular frame plate, the sealing gasket is used in conjunction with the sealing groove, and four first mounting slots are symmetrically opened on the bottom surface of the rectangular groove.

[0010] As a preferred technical solution of this utility model, the L-shaped support plate is initially positioned at the top of the T-shaped slide groove and is flipped outwards. At this time, both the first return spring and the second return spring are in their initial state.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model solves the problem of difficult alignment between the transformer top plate mounting hole and the oil tank screw hole during installation by connecting a limiting component. The T-block, limiting rod, and first reset spring work together to ensure stable movement of the T-block. The connecting base, L-shaped support plate, and semi-circular protrusion can quickly engage with the transformer body's locking groove, assisting in precise alignment between the mounting hole and the screw hole and improving installation efficiency.

[0013] When the pressing frame is pressed down, the control lever is pushed, and the third reset spring causes the push rod to lift the rectangular frame plate, so that the sealing gasket fits tightly, effectively preventing oil leakage in the tank, ensuring the safe and stable operation of the transformer, and reducing maintenance costs.

[0024] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0025] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 9 The present invention will be further described below.

[0026] A transformer tank structure includes a tank body 1, a transformer top plate 2 fixedly mounted on the top of the tank body 1 by bolts, a pressing frame 3 fixedly mounted on the bottom of the transformer top plate 2, a sealing groove 4 formed at the bottom of the transformer top plate 2, a transformer body 5 fixedly mounted on the bottom of the transformer top plate 2, a snap-fit ​​groove 6 formed on the outer side of the transformer body 5, two support bases fixedly mounted on the bottom of the transformer body 5, T-shaped sliding grooves 7 formed on the inner side of the tank body 1, a limit rod 8 fixedly mounted on the inner bottom surface of the T-shaped sliding grooves 7, four connection limit components symmetrically arranged inside the tank body 1 to improve installation efficiency, the T-shaped sliding grooves 7 working in conjunction with the connection limit components, a sealing component inside the tank body 1, and the pressing frame 3 working in conjunction with the sealing component.

[0027] In this implementation scheme, by setting up the tank body 1, space and location are provided for the installation of all other components, enclosing the internal transformer body 5 and various components, protecting them from external environmental interference and damage, and ensuring the stable operation of the transformer body 5. The transformer top plate 2 is fixedly connected to the top of the tank body 1 by bolts, playing a key role in sealing the top of the tank, preventing dust, debris and other external pollutants from entering the tank, maintaining a clean environment inside the tank, and protecting the internal components. The pressing frame 3 cooperates with the sealing component to achieve the sealing function of the tank. When pressure is applied to the pressing frame 3, it pushes the sealing component to move, and the sealing groove 4 fits tightly with the sealing gasket 23 in the sealing component, and the two fit together to form a seal. The structure effectively prevents oil leakage from the tank. The transformer body 5, as the core component of the transformer, undertakes important functions such as voltage transformation and power transmission. During the installation of the transformer body 5, the semi-circular protrusion 14 is inserted into the snap-fit ​​groove 6. This matching method can quickly and accurately determine the position of the transformer body 5 in the tank, reducing the number of times the transformer position needs to be adjusted during installation. The T-shaped slide 7 provides a precise sliding track for the T-shaped block 10 in the connecting limit assembly. The limit rod 8 restricts the movement direction and range of the T-shaped block 10. The connecting limit assembly solves the problem of difficult alignment between the mounting hole of the transformer top plate 2 and the screw hole of the tank during installation, improving installation efficiency. The sealing assembly prevents oil leakage from the tank.

[0028] Specifically, the connecting limiting component includes a T-shaped block 10, which is movably installed inside the T-shaped slide 7. A round hole is provided at the top of the T-shaped block 10, through which the limiting rod 8 passes. A first return spring 9 is fixedly installed at the bottom of the T-shaped block 10, and the other end of the first return spring 9 is fixedly installed to the inner bottom surface of the T-shaped slide 7. A trapezoidal mounting groove 11 is provided at one end of the T-shaped block 10.

[0029] In this embodiment, by setting a T-shaped block 10, the movement within the T-shaped slide 7 achieves the cooperation between the connecting limiting component and the T-shaped slide 7. The cooperation between the top round hole and the limiting rod 8 ensures the accuracy of its movement direction and avoids deviation during installation. The first return spring 9 connects the bottom of the T-shaped block 10 to the inner bottom surface of the T-shaped slide 7. When no external force is applied, it keeps the T-shaped block 10 in its initial position, providing a stable starting state for each installation operation. When the T-shaped block 10 is subjected to external force and moves downward, the first return spring 9 is compressed. After the external force disappears, the first return spring 9 will push the T-shaped block 10 to the top of the T-shaped slide 7, ensuring that the connecting limiting component can be reused and improving installation efficiency. The trapezoidal mounting groove 11 provides a stable installation space and movement guide for the connecting base 12.

[0030] Specifically, the connecting limit assembly also includes a connecting base 12, which is movably installed inside the trapezoidal mounting groove 11 via a round rod. An L-shaped support plate 13 is fixedly installed at one end of the connecting base 12, and a semi-circular protrusion 14 is fixedly installed on one side of the L-shaped support plate 13. The semi-circular protrusion 14 is used in conjunction with the snap-fit ​​groove 6. A second return spring 15 is fixedly installed on one side of the inclined surface of the trapezoidal mounting groove 11, and the other end of the second return spring 15 is fixedly installed on the side of the L-shaped support plate 13 near the connecting base 12.

[0031] In this embodiment, by setting a connecting base 12, a round rod moves within the trapezoidal mounting groove 11, providing a flexible rotational connection for the L-shaped support plate 13. This allows the L-shaped support plate 13 to change its angle according to installation requirements, ensuring that the semi-circular protrusion 14 can smoothly engage with the snap-fit ​​groove 6 on the transformer body 5. This plays a crucial transitional and connecting role during the installation of the transformer body 5, ensuring the overall functionality of the connection limiting assembly. When installing the transformer body 5, the L-shaped support plate 13 first contacts the bottom of the transformer body 5. The connecting base 12 rotates around its axis, causing the semi-circular protrusion 14 to approach the snap-fit ​​groove 6. When the L-shaped support plate 13 rotates to the appropriate position, the semi-circular protrusion 14 inserts into the snap-fit ​​groove 6, thereby initially positioning and supporting the transformer body 5. After insertion, the L-shaped support plate 13 fits against the bottom side of the transformer body 5, further restricting the displacement of the transformer body 5 and improving the stability of the installation. During the rotation of the L-shaped support plate 13, the semi-circular protrusion 14 inserts into the snap-fit ​​groove 6, which can quickly determine the position of the transformer body 5 in the oil tank, reducing the time for adjusting the position of the transformer body 5 during installation and improving installation efficiency. The second return spring 15 is installed between one side of the inclined surface of the trapezoidal mounting groove 11 and the side of the L-shaped support plate 13 near the connecting base 12. During the rotation of the L-shaped support plate 13, the second return spring 15 is stretched and stores elastic potential energy. After the transformer body 5 is disassembled, the second return spring 15 can make the L-shaped support plate 13 quickly return to its initial outward flipped state, which is convenient for the next installation operation.

[0032] Specifically, the sealing assembly includes a rectangular groove 16, a rectangular frame plate 22 is movably installed inside the rectangular groove 16, a sealing gasket 23 is fixedly installed on the top of the rectangular frame plate 22, the sealing gasket 23 is used in conjunction with the sealing groove 4, and four first mounting slots 17 are symmetrically opened on the bottom surface inside the rectangular groove 16. A push rod 18 is movably installed inside the first mounting slot 17, and the top of the push rod 18 is fixedly installed to the bottom of the rectangular frame plate 22.

[0033] In this embodiment, a rectangular groove 16 is provided to provide installation space and a moving track for the rectangular frame plate 22. The rectangular frame plate 22 can move stably up and down inside it. The rectangular frame plate 22 serves as the carrier of the sealing gasket 23. Under the push of the push rod 18, the sealing gasket 23 moves up and down. The sealing gasket 23 is in direct contact with the sealing groove 4. Utilizing its good elasticity and sealing performance, it fits tightly against the sealing groove 4 under the push of the rectangular frame plate 22, effectively preventing oil leakage from the oil tank. The first mounting groove 17 provides a stable moving space for the push rod 18, ensuring that the push rod 18 can only move up and down in the specified direction, thereby accurately pushing the rectangular frame plate 22 and ensuring the stability and reliability of the sealing assembly. This allows the sealing action to be accurately achieved. The top of the push rod 18 is fixedly connected to the bottom of the rectangular frame plate 22, converting the external force into the power to push the rectangular frame plate 22, which in turn drives the rectangular frame plate 22 and the sealing gasket 23 to move up and down, realizing the functions of sealing and releasing the seal.

[0034] Specifically, the sealing assembly also includes a second mounting groove 20, which is located inside the oil tank body 1 on one side. The second mounting groove 20 is connected to the first mounting groove 17. A control rod 19 is movably mounted inside the second mounting groove 20 via a round rod. A third return spring 21 is fixedly mounted on one side of the control rod 19. The third return spring 21 is fixedly mounted to the bottom surface of the inside of the first mounting groove 17.

[0035] In this embodiment, the second mounting groove 20 provides space for the control rod 19 to be installed and moved, and also serves as a channel connecting the first mounting groove 17. This allows the movement of the control rod 19 to indirectly affect the action of the push rod 18 through the connection with the first mounting groove 17, thereby controlling the sealing and unsealing states of the sealing assembly. When the pressing frame 3 is pressed down, the control rod 19 is subjected to external force and moves within the second mounting groove 20, which in turn pushes the push rod 18 upward, causing the rectangular frame plate 22 and the sealing gasket 23 to move upward, thus achieving the sealing function. When the pressing frame 3 releases pressure, the control rod 19 returns to its original position under the action of the third return spring 21, and the push rod 18 and the rectangular frame plate 22 will descend under the action of gravity, releasing the sealing state and facilitating maintenance and other operations. The third return spring 21...

[0036] Specifically, the L-shaped support plate 13 is initially positioned at the top of the T-shaped slide groove 7, with its orientation flipped outwards. At this time, both the first return spring 9 and the second return spring 15 are in their initial states.

[0037] In this embodiment, by setting an L-shaped support plate 13, initially flipped outwards, it can easily contact and interact with the bottom of the transformer body 5 during installation. During installation, the bottom of the transformer body 5 pushes the L-shaped support plate 13 to rotate around the connecting base 12, causing the semi-circular protrusion 14 to engage with the snap-fit ​​groove 6 of the transformer body 5, achieving rapid positioning and initial fixation, improving installation efficiency. When the transformer body 5 is installed, the L-shaped support plate 13 drives the T-shaped block 10 to move downwards, compressing the first return spring 9. This is achieved when the transformer body 5 is disassembled. Afterwards, the first return spring 9 will push the T-shaped block 10 back to its initial position, thereby causing the L-shaped support plate 13 to return to the top of the T-shaped slide 7, preparing for the next installation. This ensures that the connection limit assembly can be reused, improving the convenience and efficiency of operation. When the transformer body 5 pushes the L-shaped support plate 13 to rotate, the second return spring 15 is stretched, storing elastic potential energy, allowing the L-shaped support plate 13 to fit tightly against the bottom side of the transformer body 5, enhancing the fixing effect. When disassembling the transformer body 5, it can quickly restore the L-shaped support plate 13 to its initial outward flipped state, facilitating subsequent operations.

[0038] In summary: When using this utility model, the L-shaped support plate 13 is positioned at the top of the T-shaped slide groove 7, in an outward-flipped state. At this time, both the first return spring 9 and the second return spring 15 are initially in an uncompressed or unstretched state. The transformer body 5 is slowly placed into the oil tank body 1, causing its bottom to gradually approach the L-shaped support plate 13. When the bottom of the transformer body 5 contacts the L-shaped support plate 13, it pushes the L-shaped support plate 13 to rotate around the connecting base 12. The connecting base 12 rotates flexibly within the trapezoidal mounting groove 11 via a round rod. The L-shaped support plate 13 provides support and space for rotation. As the L-shaped support plate 13 rotates, the second return spring 15 is stretched, storing elastic potential energy. The semi-circular protrusion 14 on the L-shaped support plate 13 gradually approaches the snap-fit ​​groove 6 on the outside of the transformer body 5. At the same time, the L-shaped support plate 13 drives the connecting base 12 and the T-shaped block 10 to move downward in the T-shaped slide groove 7. The first return spring 9 is compressed. When the L-shaped support plate 13 rotates to the appropriate angle, the semi-circular protrusion 14 is precisely inserted into the snap-fit ​​groove 6, realizing the snap-fit ​​of the transformer body 5. During the initial positioning, the L-shaped support plate 13 fits against the bottom side of the transformer body 5, further restricting its displacement and enhancing installation stability. During the placement of the transformer body 5, the pressing frame 3 moves into the interior of the tank body 1 along with the transformer top plate 2. The pressing frame 3 pushes the control rod 19 to move in the second mounting groove 20. The control rod 19, through the communication structure with the first mounting groove 17, pushes the push rod 18 to move upward in the first mounting groove 17. The top of the push rod 18 is fixed to the bottom of the rectangular frame plate 22, causing the rectangular frame plate 22 and the sealing gasket 23 to move upward. When the transformer top plate 2 is in contact with the top of the tank body 1, the sealing gasket 23 will rise to fit tightly with the sealing groove 4 at the bottom of the transformer top plate 2, forming a sealing structure, effectively preventing oil leakage in the tank and completing the tank sealing work. After the transformer body 5 is positioned and the tank is sealed, bolts are used to fix the transformer top plate 2 to the top of the tank body 1, and nuts are tightened to make the transformer top plate 2 firmly installed on the tank body 1.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
