Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with shock absorption function. Background Technology

[0002] Transformers generate a lot of vibration during use or transportation. The transformer contains a large number of precision components. When these components are subjected to large vibrations, they may become loose, affecting their efficiency. Existing transformers usually use elastic or magnetic vibration damping to reduce vibration. After the vibration is reduced, the amplitude of the transformer's vibration is reduced, but the reaction force will still cause the transformer to shake, resulting in increased wear and reduced service life.

[0003] Patent CN202022223823.4 discloses a transformer housing with shock absorption function. The first shock absorption mechanism of this patent can absorb shock when the transformer shakes in four directions: front, back, left, and right. Compared with the existing transformer housing with only vertical shock absorption function, the shock absorption effect is better and the service life is longer. The second shock absorption mechanism can play an auxiliary role in shock absorption, further improving the shock absorption effect, thereby reducing the noise generated by the transformer during operation and avoiding damage caused by vehicle shaking during the transportation of the transformer. Although this patent solves the above problems, there are still problems with the slow shock absorption process, which cannot stop the transformer from moving quickly and causes severe wear on the transformer. Therefore, it is necessary to design a transformer with shock absorption function that can quickly stop the transformer from moving, reduce transformer wear, and play a better protective role. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer with shock absorption function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a transformer with vibration damping function, comprising a transformer body, a protective inner shell fixedly connected to the outer surface of the transformer body, sliding seats fixedly connected to the upper and lower sides of the protective inner shell, a horizontal sliding rod slidably connected to the inner surface of the sliding seat, a protective outer shell fixedly connected to both ends of the horizontal sliding rod, a vertical sliding rod fixedly connected to the upper and lower sides of the inner wall of the protective outer shell, a sliding shaft slidably connected to the outer surface of the vertical sliding rod, an X-shaped elbow connecting rod hinged to the outer side of the sliding shaft, energy dissipation devices for reducing excess energy during vibration and extending the service life of the vibration damping structure provided on both sides of the transformer body, and energy dissipation devices for preventing the transformer from vibrating excessively when the vibration amplitude is too large. The tilting support device has an X-shaped toggle link hinged to the inner side of the protective structure on the side away from the sliding shaft. Springs are installed between the two ends of the sliding seat and the two sides of the inner wall of the protective shell. Two sliding shafts are slidably connected to the upper and lower sides of the vertical sliding rod, and a tension spring is installed between the two sliding shafts. When the protective shell and the transformer body are affected by external factors and vibrate, the vibration force is first transmitted to the inner protective shell, and then transmitted from the inner protective shell to the sliding seat. The vibration force causes the sliding seat to slide left and right on the horizontal sliding rod and compress the spring, causing the X-shaped toggle link to close. During the closing process of the X-shaped toggle link, it drives the upper and lower sliding shafts to slide to the upper and lower ends of the vertical sliding rod, so that the two sliding shafts move away from each other. At this time, the two sliding shafts pull the tension spring, thereby forming tension on both sides of the inner protective shell.

[0006] According to the above technical solution, the energy dissipation device includes a push shaft, a lead screw, and a connecting block. The push shaft is fixedly connected to both sides of the inner protective frame. The lead screw is movably connected to the inner surface of the push shaft. The connecting block is fixedly connected to the outer surface of the push shaft. The energy dissipation device also includes a connector, an expansion rod, a friction arc plate, a friction sleeve, and a limiting plate. The connector is hinged to both sides of the connecting block. The expansion rod is hinged to the end of the connector away from the connecting block. The friction arc plate is fixedly connected to the side of the expansion rod away from the push shaft. The friction sleeve is fixedly connected to both sides of the inner wall of the protective shell. The limiting plate is fixedly connected to both sides of the inner wall of the protective shell. The lead screw rotatably passes through both sides of the protective shell. The lead screw is rotatably connected to the inner surface of the limiting plate. The limiting plate is fixedly connected to the inner wall of the friction sleeve. A sliding groove is provided on the inner side of the expansion rod, and the end of the expansion rod away from the push shaft is slidably connected to the inner surface of the sliding groove. The lead screw is non-self-locking. When the transformer body and the protective inner shell sway left and right, it drives the push shaft to move left and right. When the push shaft moves left and right, the friction lead screw moves and contacts the limit plate. When the push shaft moves and contacts the limit plate, the end of the connecting piece that is hinged to the connecting block moves with the push shaft. Since one end of the expansion rod is in contact with the inner wall of the protective shell, when the end of the connecting piece that is hinged to the connecting block moves closer to the inner wall of the protective shell, its other end will push the expansion rod outward, so that the expansion rod slides open in the sliding groove. During the process of the expansion rod opening, it drives the friction arc plate to open. Finally, the friction arc plate contacts the inner wall of the friction sleeve and becomes tensioned. At this time, the push shaft moves in the opposite direction, which will generate friction between the friction arc plate and the friction sleeve.

[0007] According to the above technical solution, the supporting device includes a supporting block, a supporting plate, and a hook. The supporting block is fixedly connected to both sides of the protective shell. The supporting plate is hinged to the end of the supporting block away from the protective shell. The hook is fixedly connected to the end of the lead screw that passes through the protective shell. The supporting device also includes a hanging plate, a telescopic rod, and a slider. The hanging plate is fixedly connected to the side of the supporting plate near the hook. The telescopic rod is hinged to both sides of the protective shell. The slider is hinged to the bottom end of the telescopic rod. A second sliding groove is formed on the inner side of the supporting plate, and the slider is slidably connected to the inner surface of the second sliding groove. A torsion spring is provided at the hinge point between the support plate and the support block. The telescopic rod is self-locking. When the push shaft moves left and right on the surface of the lead screw, it causes the lead screw to rotate slightly. When the vibration force is too large and the movement of the push shaft is too large, the rotation amplitude of the lead screw becomes relatively larger. At this time, the lead screw can drive the hook to rotate and disengage from the hanging plate. When the hanging plate loses the lock of the hook, the torsion spring between the support plate and the support block causes the support plate to rotate and reset to be flush with the ground. During the rotation of the support plate, the telescopic rod is pulled to extend due to gravity. When the telescopic rod reaches its extension limit, its internal self-locking mechanism locks the two end rods.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0009] This invention, by setting up a vertical sliding rod, a sliding shaft, and an X-shaped elbow connecting rod, allows the sliding seat to slide left and right on the horizontal sliding rod and compress the spring. After the spring absorbs the shock, the force of the vibration is reduced, thus avoiding damage to the transformer body. The two sliding shafts pull the tension spring, thereby forming tension on both sides of the protective inner shell. The tension causes the transformer body and the protective inner shell to stop quickly, reducing wear and providing better protection for the transformer body.

[0010] This invention, by incorporating a connecting block, connecting piece, expansion rod, friction arc plate, friction sleeve, and limiting plate, allows the friction screw to be rubbed when the push shaft moves left and right. This friction enables the vibration force to be evenly reduced and heat to be generated, thus dissipating the force as heat. This prevents all the force from concentrating on the spring, causing the spring to do work frequently and ultimately reducing its lifespan. The friction force generated between the friction arc plate and the friction sleeve, after being enhanced, can generate heat more quickly, reducing the vibration force and promoting the protective effect of the force on the spring, further improving the lifespan of the spring.

[0011] This invention, by incorporating a support plate, hooks, hanging plates, telescopic rods, and sliders, increases the support area of ​​the device after the support plate is extended, making the device more stable. When the protective shell is about to tip over due to an impact from other objects, it is stopped by the telescopic rod, thus preventing it from falling over and improving the safety of the device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1-7 One embodiment of the present invention is as follows: A transformer with shock absorption function includes a transformer body 1. A protective inner shell 2 is fixedly connected to the outer surface of the transformer body 1. Sliding seats 21 are fixedly connected to the upper and lower sides of the protective inner shell 2. A horizontal sliding rod 22 is slidably connected to the inner surface of the sliding seat 21. A protective outer shell 23 is fixedly connected to both ends of the horizontal sliding rod 22. A vertical sliding rod 24 is fixedly connected to the upper and lower sides of the inner wall of the protective outer shell 23. A sliding shaft 25 is slidably connected to the outer surface of the vertical sliding rod 24. An X-shaped elbow connecting rod 26 is hinged to the outer side of the sliding shaft 25. The sliding seat 21 slides left and right on the horizontal sliding rod 22 and compresses the spring. After the spring absorbs the shock, the vibration force is reduced, thus preventing damage to the transformer body 1. Energy dissipation devices 3 are provided on both sides of the main body 1 to reduce excess energy during vibration and extend the service life of the vibration damping structure. Support devices 4 are provided on both sides of the protective shell 23 to prevent the transformer from tipping over when the vibration amplitude is too large. The side of the X-shaped elbow connecting rod 26 away from the sliding shaft 25 is hinged to the inner side of the protection. Springs are provided between the two ends of the sliding seat 21 and the inner walls of the protective shell 23. Two sliding shafts 25 are slidably connected to the upper and lower sides of the vertical sliding rod 24, and a tension spring is provided between the two sliding shafts 25. The two sliding shafts 25 pull the tension spring, thereby forming tension on both sides of the protective inner shell 2. The tension makes the transformer body 1 and the protective inner shell 2 stop quickly, reducing wear and providing better protection for the transformer body 1.

[0024] Working principle: When the protective outer shell 23 and the transformer body 1 are affected by external factors and vibrate, the vibration force is first transmitted to the inner protective shell 2, and then from the inner protective shell 2 to the sliding seat 21. The vibration force causes the sliding seat 21 to slide left and right on the horizontal sliding rod 22 and squeeze the spring. After the spring absorbs the shock, it reduces the vibration force and avoids damage to the transformer body 1. When the transformer body 1 and the inner protective shell 2 are affected by vibration and sway left and right, they will squeeze the X-shaped elbow connecting rod 26, causing the X-shaped elbow connecting rod 26 to close together. During the closing process of the X-shaped elbow connecting rod 26, it drives the upper and lower sliding shafts 25 to slide towards the upper and lower ends of the vertical sliding rod 24, so that the two sliding shafts 25 move away from each other. At this time, the two sliding shafts 25 pull the tension spring, thereby forming tension on both sides of the inner protective shell 2. The tension causes the transformer body 1 and the inner protective shell 2 to stop quickly and reduce wear, thus providing better protection for the transformer body 1.

[0025] Please see Figure 1-7 Based on the above embodiments, another embodiment of the present invention includes an energy dissipation device 3. The energy dissipation device 3 includes a push shaft 31, a lead screw 32, and a connecting block 33. The push shaft 31 is fixedly connected to both sides of the protective inner frame, the lead screw 32 is movably connected to the inner surface of the push shaft 31, and the connecting block 33 is fixedly connected to the outer surface of the push shaft 31. When the push shaft 31 moves left and right, it rubs against the lead screw 32. The friction can evenly reduce the force of vibration and generate heat, so that the force is dissipated as heat, avoiding all the force being concentrated on the spring, causing the spring to do work frequently and ultimately reducing the service life of the spring. The energy dissipation device 3 also includes a connecting piece 34, an expansion rod 35, a friction arc plate 36, a friction sleeve 37, and a limiting plate 38. The connecting piece 34 is hinged to both sides of the connecting block 33, and the expansion rod 35 is hinged to the connecting piece 36. 4. At the end away from the connecting block 33, the friction arc plate 36 and the expansion rod 35 are fixedly connected on the side away from the push shaft 31. The friction sleeve 37 is fixedly connected to both sides of the inner wall of the protective shell 23. The limiting plate 38 is fixedly connected to both sides of the inner wall of the protective shell. The lead screw 32 rotates through both sides of the protective shell. The lead screw 32 is rotatably connected to the inner surface of the limiting plate 38. The limiting plate 38 is fixedly connected to the inner wall of the friction sleeve 37. A sliding groove is opened on the inner side of the limiting plate 38, and the end of the expansion rod 35 away from the push shaft 31 is slidably connected to the inner surface of the sliding groove. The lead screw 32 is non-self-locking. Friction is generated between the friction arc plate 36 and the friction sleeve 37. After the friction is enhanced, heat can be generated more quickly to reduce the vibration, promote the protective effect of the force on the spring, and further improve the service life of the spring.

[0026] Working principle: When the transformer body 1 and the protective inner shell 2 sway left and right, they drive the push shaft 31 to move left and right. When the push shaft 31 moves left and right, it rubs against the lead screw 32. Friction can evenly reduce the force of vibration and generate heat, so that the force is converted into heat and dissipated. This avoids all the force being concentrated on the spring, causing the spring to do work frequently and ultimately reducing the spring's service life. When the push shaft 31 moves and contacts the limit plate 38, the end of the connecting piece 34 that is hinged to the connecting block 33 moves with the push shaft 31. Also, because one end of the expansion rod 35 is in contact with the inner wall of the protective shell 23, when the connecting piece 34 and the connecting block 33 move together, the spring will move. When one end of the connecting block 33 is hinged toward the inner wall of the protective shell 23, the other end pushes the expansion rod 35 outward, causing the expansion rod 35 to slide open in the first slide groove. During the opening of the expansion rod 35, the friction arc plate 36 opens, and finally the friction arc plate 36 comes into contact with the inner wall of the friction sleeve 37, becoming a tensioned state. At this time, the push shaft 31 moves in the opposite direction, which will generate friction between the friction arc plate 36 and the friction sleeve 37. After the friction is enhanced, heat can be generated more quickly to reduce the shock, promote the protective effect of the force on the spring, and further improve the service life of the spring.

[0027] Please see Figure 1-7 Based on the above embodiments, another embodiment of the present invention includes a support device 4, which includes a support block 41, a support plate 42, and a hook 43. The support block 41 is fixedly connected to both sides of the protective shell 23, the support plate 42 is hinged to the end of the support block 41 away from the protective shell 23, and the hook 43 is fixedly connected to the end of the lead screw 32 that passes through the protective shell. After the support plate 42 is unfolded, it increases the support area of ​​the device, making the device more stable. The support device 4 also includes a hanging plate 44, a telescopic rod 45, and a sliding plate 46. Block 46 and hanging plate 44 are fixedly connected to the side of support plate 42 near hook 43. Telescopic rod 45 is hinged to both sides of protective shell 23. Slider 46 is hinged to the bottom of telescopic rod 45. A second sliding groove is opened on the inner side of support plate 42, and slider 46 is slidably connected to the inner surface of sliding groove 2. A torsion spring is provided at the hinge point between support plate 42 and support block 41. Telescopic rod 45 is self-locking. When protective shell 23 is about to fall due to impact from other external objects, it is stopped by telescopic rod 45, thus preventing it from falling and improving the safety of the device.

[0028] Working principle: When the push shaft 31 moves left and right on the surface of the lead screw 32, it causes the lead screw 32 to rotate slightly. When the vibration force is too large, causing the push shaft 31 to move too much, the lead screw 32 rotates more. At this time, the lead screw 32 can drive the hook 43 to rotate and disengage from the hanging plate 44. When the hanging plate 44 is no longer locked by the hook 43, the torsion spring between the support plate 42 and the support block 41 drives the support plate 42 to rotate and reset to be flush with the ground. During the rotation of the support plate 42, the telescopic rod 45 is pulled to extend due to gravity. When the telescopic rod 45 reaches its extension limit, its internal self-locking mechanism locks the two end rods. After the support plate 42 is unfolded, it increases the support area of ​​the device, making the device more stable. When the protective shell 23 is about to tip over due to the impact of other foreign objects, it is stopped by the telescopic rod 45, thus preventing it from falling and improving the safety of the device.
