A seismic-resistant transformer with a support and reinforcement structure

Abstract

This invention discloses a shock-resistant transformer with a support and reinforcement structure, comprising a transformer body located between two utility pole bodies. The two utility pole bodies are arranged opposite each other, and annular positioning frames are fixedly installed on the surface of each utility pole body. Each of the two annular positioning frames has a buffer load-bearing frame fixedly connected to its opposite side via a fixing plate. This invention relates to the field of transformer technology. This shock-resistant transformer with a support and reinforcement structure utilizes annular positioning frames to install buffer load-bearing frames on the surface of the utility pole body, and a load-bearing crossbeam is provided between the two buffer load-bearing frames. Rubber blocks are used for insulation, in conjunction with springs. These structural features allow the springs to isolate the concave pressure port from the buffer load-bearing frames. When the utility pole body is impacted and shaken, the buffer crossbeam and the buffer load-bearing frame first compress the rubber blocks, which possess high elasticity and insulation properties.

Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to an earthquake-resistant transformer with a support and reinforcement structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] In real life, most transformers are installed in residential areas to supply power to communities and homes. To improve safety and protection, transformers are typically mounted on utility poles using brackets. While current mounting components and methods effectively secure the transformer, they still have significant drawbacks in practical use, such as:

[0004] When installing a transformer and a utility pole, it is usually necessary to use brackets and bolt assemblies for rigid installation. This can cause the transformer to vibrate when operating at high power. When the transformer vibrates, it will collide with the bracket, causing the bracket to resonate and generate noise. Furthermore, because the transformer and the utility pole are rigidly connected, the impact of the utility pole will be directly transmitted to the transformer.

[0005] Therefore, a seismic-resistant transformer with a support and reinforcement structure is now designed to address this type of defect. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a seismic-resistant transformer with a support and reinforcement structure, which solves the problem of low seismic resistance in existing transformers.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seismic-resistant transformer with a support and reinforcement structure, comprising a transformer body located between two utility pole bodies, the two utility pole bodies being arranged opposite to each other, annular positioning frames being fixedly installed on the surface of each utility pole body, and buffer load-bearing frames being fixedly connected to opposite sides of each of the two annular positioning frames via fixing plates, and plug-in bottom boxes being fixedly connected to the front and rear sides of the bottom of the buffer load-bearing frames via openings, and rectangular sockets for use with the plug-in bottom boxes being provided on the front and rear sides of the top of the buffer load-bearing frames, and rubber blocks for use with the rectangular sockets being provided on the inner side of the plug-in bottom boxes.

[0008] Preferably, a load-bearing crossbeam is slidably installed between the inner sides of the two buffer load-bearing frames, and a backstop crossbeam is fixedly connected to both ends of the load-bearing crossbeam and located on the inner side of the buffer load-bearing frame. The front and rear parts of the two backstop crossbeams on opposite sides are provided with concave pressure holes for use with rubber blocks.

[0009] Preferably, the front and rear parts of the two blocking cross seats on opposite sides are fixedly connected to springs by fixing blocks, and the end of the spring away from the blocking cross seat is fixedly connected to the inner wall of the buffer load-bearing frame.

[0010] Preferably, the front and rear sides of the load-bearing crossbeam are fixedly connected to load-bearing recesses by fixing blocks. One side of the load-bearing recess is provided with a connecting transverse groove that extends to the other side. Both sides of the surface of the load-bearing crossbeam are provided with cross guide grooves that extend to the rear. The front and rear sides of the bottom of the inner cavity of the load-bearing recess are provided with first threaded grooves, and the first threaded grooves extend through the connecting transverse grooves and extend to the bottom of the load-bearing recess.

[0011] Preferably, a sliding plate is slidably installed on the inner side of the cross guide groove, and an anti-collision frame is fixedly installed on the top of the sliding plate by a bracket. The front and rear parts of the anti-collision frame are both fixedly connected to vertical connecting rods by fixing seats.

[0012] Preferably, the bottom end of the vertical connecting rod is fixedly connected to an L-shaped insert plate that mates with the docking horizontal groove via a fixing block. The front and rear sides of the top of the L-shaped insert plate are provided with second threaded grooves that mate with the first threaded groove, and the first threaded groove and the second threaded groove overlap.

[0013] Preferably, the lower parts of the two anti-collision frames on opposite sides are fixedly connected by brackets to arc-shaped pressure frames that cooperate with the rubber blocks. The front and rear sides of the bottom of the arc-shaped pressure frames are rotatably connected to rollers through openings, and several rollers are provided.

[0014] Preferably, the bottom of the transformer body is fixedly connected to a strip seat by a bracket, and four strip seats are provided. The strip seats are located inside the mating transverse groove, and the inner side of the strip seats is threadedly connected to a threaded bolt that cooperates with the first threaded groove and the second threaded groove.

[0015] This invention provides a seismic-resistant transformer with a support and reinforcement structure. Compared with existing technologies, it has the following advantages:

[0016] (1) The earthquake-resistant transformer with a support and reinforcement structure has a buffer load-bearing frame installed on the surface of the utility pole body using a ring positioning frame, and a load-bearing crossbeam frame set between the two buffer load-bearing frames. Rubber blocks are used for isolation, and springs are used in conjunction with the structure. The springs can isolate the concave pressure hole from the buffer load-bearing frame. When the utility pole body is impacted and shaken, the blocking crossbeam and the buffer load-bearing frame will first squeeze the rubber block. The rubber block has high elasticity and isolation properties, so the rubber block will absorb most of the impact force and will not be directly transmitted to the transformer body, thereby effectively improving the earthquake resistance of the transformer body.

[0017] (2) The anti-vibration transformer with a bracket reinforcement structure has two anti-collision guard frames installed on the inner side of the cross guide groove using a sliding plate, and is used in conjunction with an arc-shaped pressure frame, an L-shaped insert plate and a threaded bolt. The two anti-collision guard frames can clamp and restrain the transformer body, ensuring that the components will not resonate when the transformer body vibrates. At the same time, the arc-shaped pressure frame can also limit and fix the rubber block, ensuring the stability of the equipment during daily use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 The present invention provides a technical solution: a shock-resistant transformer with a support and reinforcement structure, including a transformer body 2 located between two utility pole bodies 1. The two utility pole bodies 1 are arranged opposite to each other. A ring positioning frame 3 is fixedly installed on the surface of the utility pole body 1. A buffer load-bearing frame 4 is fixedly connected to the opposite side of the two ring positioning frames 3 through a fixing plate. A plug-in bottom box 5 is fixedly connected to the front and rear sides of the bottom of the buffer load-bearing frame 4 through openings. A rectangular plug 6 is provided on the front and rear sides of the top of the buffer load-bearing frame 4 to cooperate with the plug-in bottom box 5. A rubber block 7 is provided on the inner side of the plug-in bottom box 5 to cooperate with the rectangular plug 6.

[0029] Furthermore, a load-bearing crossbeam 8 is slidably installed between the inner sides of the two buffer load-bearing frames 4. At both ends of the load-bearing crossbeam 8 and located inside the buffer load-bearing frame 4, a retaining crossbeam 9 is fixedly connected. The front and rear parts of the opposite side of the two retaining crossbeams 9 are provided with concave pressure holes 10 that cooperate with the rubber block 7. The front and rear parts of the opposite side of the two retaining crossbeams 9 are fixedly connected with springs 11 by fixing blocks, and the end of the spring 11 away from the retaining crossbeam 9 is fixedly connected to the inner wall of the buffer load-bearing frame 4.

[0030] Furthermore, the front and rear sides of the load-bearing beam frame 8 are fixedly connected to the load-bearing recess 12 by fixing blocks. One side of the load-bearing recess 12 is provided with a connecting transverse groove 13 that extends to the other side. Both sides of the surface of the load-bearing beam frame 8 are provided with cross guide grooves 14 that extend to the rear. The front and rear sides of the bottom of the inner cavity of the load-bearing recess 12 are provided with first threaded grooves 15, and the first threaded grooves 15 extend through the connecting transverse grooves 13 and extend to the bottom of the load-bearing recess 12. A sliding plate 16 is slidably installed on the inner side of the cross guide groove 14. The top of the sliding plate 16 is fixedly installed with a collision protection frame 18 by a bracket. The inner side of the collision protection frame 18 is wrapped with a rubber layer. The front and rear of the collision protection frame 18 are fixedly connected with vertical connecting rods 21 by fixing seats.

[0031] The bottom end of the vertical connecting rod 21 is fixedly connected to an L-shaped insert plate 19 that is used to cooperate with the docking horizontal groove 13. The front and rear sides of the top of the L-shaped insert plate 19 are provided with second threaded grooves 20 that are used to cooperate with the first threaded groove 15, and the first threaded groove 15 and the second threaded groove 20 overlap.

[0032] Among them, the lower part of the two anti-collision guard frames 18 on opposite sides is fixedly connected to the arc-shaped pressure frame 22 for use with rubber block 7 by the bracket. The front and rear sides of the bottom of the arc-shaped pressure frame 22 are rotatably connected to the roller 23 through openings, and there are several rollers 23. The bottom of the transformer body 2 is fixedly connected to the strip seat 24 by the bracket, and there are four strip seats 24. The strip seat 24 is located inside the docking transverse groove 13. The inner side of the strip seat 24 is threadedly connected to the threaded bolt 25 for use with the first threaded groove 15 and the second threaded groove 20.

[0033] Before use, first use bolt assemblies to install two annular positioning brackets 3 onto the surface of the opposite utility pole body 1. Then, the operator pushes the load-bearing crossbeam 8 left and right so that the concave pressure port 10 is aligned with the plug-in bottom box 5. Then, the rubber block 7 is inserted into the inside of the plug-in bottom box 5 through the rectangular plug 6. At this time, the rubber block 7 is also located inside the concave pressure port 10. Then, the transformer body 2 is installed on the top of the load-bearing crossbeam 8. First, the strip seat 24 is placed inside the docking groove 13. Then, the operator pushes the two anti-collision guard frames 18 to close towards each other under the guidance of the cross guide groove 14 and the sliding plate 16 until the two anti-collision guard frames 18 close the transformer body 2. At the same time, the L-shaped plug 19 is also inserted into the inside of the docking groove 13. At this time, the first threaded groove 15 and the second threaded groove 20 are aligned and coincident with the strip seat 24. Then, the threaded bolt 25 is inserted into the inside of the strip seat 24 and the L-shaped plug 19 is connected to the load-bearing crossbeam 8 through the threaded connection. When the recessed frame 12 is connected, the installation of the transformer body 2 is completed. At the same time, when the two anti-collision guard frames 18 move, the arc-shaped pressure frame 22 and the roller pressure wheel 23 will press on the top of the rubber block 7 to limit the rubber block 7. In daily use, the two anti-collision guard frames 18 protect the transformer body 2. The compression of the anti-collision guard frames 18 can fit with the transformer body 2, ensuring that the transformer body 2 can reduce the impact force between itself and the structure and reduce noise during normal use. At the same time, if the utility pole body 1 connected to the ground vibrates, the inner wall of the anti-recession cross seat 9 and the buffer load-bearing frame 4 is isolated by the rubber block 7. When the buffer load-bearing frame 4 vibrates laterally with the utility pole body 1, it will only squeeze the rubber block 7 and will not directly contact the anti-recession cross seat 9. At the same time, the rubber block 7 can directly offset most of the vibration force, reduce the impact on the transformer body 2, and improve the seismic resistance of the transformer body 2.
