Description

Technical Field

[0001] The present invention relates to the technical field of transformer earthquake resistance, and specifically relates to an earthquake-resistant support structure and method for a dry-type transformer. Background Art

[0002] The earthquake-resistant support structure and method for a dry-type transformer are mainly to enhance the stability and safety of the transformer under extreme conditions such as earthquakes.

[0003] The patent with the patent publication number CN213242164U relates to a dry-type transformer with an earthquake-resistant support structure, including a dry-type transformer body and a base; a fixing plate is fixedly connected to the bottom end of the dry-type transformer; a first groove is opened on the base; the fixing plate is connected to the inner side wall of the bottom end of the first groove through an earthquake-resistant mechanism; a group of second grooves are opened on the inner side wall of the bottom end of the first groove; the earthquake-resistant mechanism includes a push rod and a shock-absorbing spring; the top end of the shock-absorbing spring is fixedly connected to the bottom end of the fixing plate, and its bottom end is fixedly connected to the inner side wall of the bottom end of the first groove. This patent provides a dry-type transformer with an earthquake-resistant support structure to solve the problem that usually a dry-type transformer needs to be installed on a support base, but the earthquake resistance performance of the base is poor, resulting in the loosening of the internal coil of the dry-type transformer when it is shaken, leading to the safety problem of using the dry-type transformer and increasing the risk coefficient.

[0004] In the above patent, the problem that usually a dry-type transformer needs to be installed on a support base, but the earthquake resistance performance of the base is poor, resulting in the loosening of the internal coil of the dry-type transformer when it is shaken, leading to the safety problem of using the dry-type transformer and increasing the risk coefficient is solved. However, when the dry-type transformer encounters a strong shaking amplitude, due to the excessive weight of the transformer itself, the inertia during shaking will increase, resulting in too strong kinetic energy when the transformer shakes towards the bottom, causing damage and higher maintenance costs. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an earthquake-resistant support structure and method for a dry-type transformer, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An earthquake-resistant support structure for a dry-type transformer includes a transformer body, a flat plate is fixedly installed at the bottom of the transformer body, a protective shell is slidably installed at the bottom of the flat plate, and a protective device, a buffer device and a stabilizing device are arranged inside the protective shell;

[0007] Among them, the protection device includes: a bottom plate, a top plate, a first shock-absorbing spring, a damper, a first clamping plate, a second clamping plate, a second shock-absorbing spring, a slider, an inclined plane block, an arc-shaped panel, a transmission plate, a reset telescopic rod and a connecting plate. The bottom plate is fixedly installed at the bottom of the inner wall of the protective shell, the top plate is fixedly installed at the bottom of the flat plate, the first shock-absorbing spring is arranged between the bottom plate and the top plate, the damper is arranged between the top plate and the bottom plate, the first clamping plate is fixedly installed at the bottom of the flat plate, a sliding groove is formed on the surface of the protective shell, the slider is slidably installed on the inner wall of the sliding groove, the second clamping plate is fixedly installed at the top of the slider, the second shock-absorbing spring is arranged between the first clamping plate and the second clamping plate, the inclined plane block is fixedly installed on the inner wall of the sliding groove, the arc-shaped panel is fixedly installed on the side of the second clamping plate close to the damper, the transmission plate is slidably installed on the surface of the inner wall of the protective shell, the reset telescopic rod is fixedly installed on the side of the top plate close to the sliding groove, one end of the connecting plate is fixedly installed at the fixed end of the reset telescopic rod, and the other end of the connecting plate is slidably installed on the inner wall of the protective shell. After the slider moves upward and no longer contacts the sliding groove, after the slider no longer contacts the sliding groove, the second clamping plate is driven to move upward by the second shock-absorbing spring, so that the second shock-absorbing spring no longer fixes and dampens the transformer body.

[0008] According to the above technical solution, the slider contacts the inclined plane block, and a first spring is arranged between the transmission plate and the protective shell, and the transmission plate is driven to reset by the first spring.

[0009] According to the above technical solution, the buffer device includes: a hollow box, a friction block, an elastic telescopic rod, a limiting plate and a brake lining. The hollow box is fixedly installed at the bottom of the inner wall of the protective shell, the friction block is fixedly installed on the side of the first clamping plate away from the second clamping plate, the elastic telescopic rod is fixedly installed at the bottom of the inner wall of the hollow box, the limiting plate is fixedly installed at the top of the free end of the elastic telescopic rod, the brake lining is slidably installed on the inner wall of the hollow box. When the friction block contacts the brake lining, the friction force between the friction block and the brake lining increases. After the friction force between the friction block and the brake lining increases, the speed of the friction block moving downward decreases, so that the speed of the transformer body moving downward decreases.

[0010] According to the above technical solution, a second spring is arranged between the brake lining and the hollow box, the brake lining contacts the limiting plate, and the brake lining is driven to reset by the second spring.

[0011] According to the above technical solution, the buffer device further includes: a fixing plate, an L-shaped plate, a reset plate, a rotating plate and a blocking plate. The fixing plate is fixedly installed on the inner wall of the hollow box. The L-shaped plate is rotatably installed between the fixing plates. The reset plate is fixedly installed on the side of the friction block close to the hollow box. The rotating plate is rotatably installed at one end of the reset plate close to the hollow box. The blocking plate is fixedly installed at the bottom of the reset plate. After the rotating plate cannot rotate downward, it will drive the L-shaped plate to rotate. The rotation of the L-shaped plate will drive the brake pad to move towards the friction block. After the brake pad moves, it will drive the limiting plate to move upward through the elastic telescopic rod to reset. The upward movement of the limiting plate will re-limit the brake pad.

[0012] According to the above technical solution, a first torsion spring is arranged between the L-shaped plate and the fixing plate. The rotating plate contacts the L-shaped plate, and the first torsion spring drives the L-shaped plate to reset.

[0013] According to the above technical solution, the stabilizing device includes: a vertical plate, a limiting ring, a square groove, a circular groove, a connecting rod, a tapered rod and an elastic plate. The vertical plate is fixedly installed at the bottom of the inner wall of the protective shell. The limiting ring is fixedly installed on the surface of the vertical plate. The square groove is opened on the side of the hollow box close to the vertical plate. The circular groove is opened at the bottom of the protective shell. The connecting rod is slidably installed in the inner wall of the square groove. One end of the connecting rod is fixedly installed on the surface of the limiting plate. The tapered rod is fixedly installed at the other end of the connecting rod. The elastic plate is rotatably installed on the circumferential surface of the tapered rod. After the elastic plate loses its limit, it is reset by the second torsion spring and drives the elastic plate to rotate in a direction away from the tapered rod. After the elastic plate rotates, it will contact the ground.

[0014] According to the above technical solution, a second torsion spring is arranged between the elastic plate and the tapered rod. The elastic plate contacts the limiting ring, and the second torsion spring drives the elastic plate to reset.

[0015] A method for using an earthquake-resistant support structure of a dry-type transformer includes the following steps;

[0016] Step 1: When the transformer body itself shakes, the kinetic energy between the bottom plate and the top plate is absorbed and released by the first shock-absorbing spring;

[0017] Step 2: When the transformer body shakes left and right, the movement of the transformer body will drive the first clamping plate to move. The movement of the first clamping plate will drive the second shock-absorbing spring to stretch. The second shock-absorbing spring absorbs and releases kinetic energy;

[0018] Step 3: The damper is used to reduce the amplitude of the left and right shaking of the transformer body, reduce the shaking amplitude of the transformer body itself, so as to enhance the stability and safety of the transformer body under extreme conditions such as earthquakes.

[0019] The present invention provides an earthquake-resistant support structure and method for a dry-type transformer. It has the following beneficial effects:

[0020] (1) In this invention, the amplitude of the left - right swaying of the transformer body is reduced by a damper, and the swaying amplitude of the transformer body itself is decreased, so as to enhance the stability and safety of the transformer body under extreme conditions such as earthquakes. By driving the second clamping plate to move upward through the second shock - absorbing spring, the second shock - absorbing spring no longer fixes and dampens the transformer body. When the vibration of the transformer body is too strong, the transformer body will move downward, and the downward movement of the transformer body will lower the overall center of gravity of the device, improving the overall stability of the device.

[0021] (2) In this invention, when the friction force between the friction block and the brake lining increases, the speed of the friction block moving downward is reduced, so that the speed of the transformer body moving downward is decreased. This prevents the large inertia caused by the large self - weight of the transformer body when moving downward, which may lead to the transformer body colliding with and damaging the protective shell. When the limiting plate moves upward, it will re - limit the brake lining. When the device completes buffering, the upward movement of the transformer body will drive the device to reset, reducing the work input during device maintenance and lowering the maintenance cost.

[0022] (3) In this invention, when the conical rod moves downward, it will insert into the ground. The insertion of the conical rod into the ground improves the overall stability of the device. When the second torsion spring resets and drives the elastic plate to rotate away from the conical rod, the elastic plate will contact the ground after rotation, increasing the contact area between the conical rod and the ground and further improving the stability of the device.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 5, an embodiment of the present invention is: an anti-seismic support structure for a dry-type transformer, including a transformer body 1. A flat plate 2 is fixedly installed at the bottom of the transformer body 1. A protective shell 3 is slidably installed at the bottom of the flat plate 2. A protective device is arranged inside the protective shell 3. The protective device includes: a bottom plate 41, a top plate 42, a first shock-absorbing spring 43, a damper 44, a first clamping plate 45, a second clamping plate 46, a second shock-absorbing spring 47, a slider 48, an inclined plane block 49, an arc-shaped panel 410, a transmission plate 411, a reset telescopic rod 412 and a connecting plate 413. The bottom plate 41 is fixedly installed at the bottom inner wall of the protective shell 3. The top plate 42 is fixedly installed at the bottom of the flat plate 2. The first shock-absorbing spring 43 is arranged between the bottom plate 41 and the top plate 42. The damper 44 is arranged between the top plate 42 and the bottom plate 41. The first clamping plate 45 is fixedly installed at the bottom of the flat plate 2. A sliding groove is formed on the surface of the protective shell 3. The slider 48 is slidably installed on the inner wall of the sliding groove. The second clamping plate 46 is fixedly installed at the top of the slider 48. The second shock-absorbing spring 47 is arranged between the first clamping plate 45 and the second clamping plate 46, reducing the swaying amplitude of the transformer body 1 itself, so as to enhance the stability and safety of the transformer body 1 under extreme conditions such as earthquakes. The inclined plane block 49 is fixedly installed on the inner wall of the sliding groove. The arc-shaped panel 410 is fixedly installed on the side of the second clamping plate 46 close to the damper 44. The transmission plate 411 is slidably installed on the inner wall surface of the protective shell 3. The reset telescopic rod 412 is fixedly installed on the side of the top plate 42 close to the sliding groove. One end of the connecting plate 413 is fixedly installed at the fixed end of the reset telescopic rod 412. The other end of the connecting plate 413 is slidably installed on the inner wall of the protective shell 3, so that when the vibration of the transformer body 1 is too strong, the transformer body 1 will move downward. The downward movement of the transformer body 1 will lower the overall center of gravity of the device and improve the overall stability of the device.

[0033] The slider 48 contacts the inclined plane block 49. A first spring is arranged between the transmission plate 411 and the protective shell 3, and the transmission plate 411 is driven to reset by the first spring.

[0034] A usage method of an anti-seismic support structure for a dry-type transformer includes the following steps:

[0035] Step 1: When the transformer body 1 shakes by itself, the kinetic energy between the bottom plate 41 and the top plate 42 is absorbed and released by the first shock-absorbing spring 43;

[0036] Step 2: When the transformer body 1 sways left and right, the movement of the transformer body 1 will drive the first clamping plate 45 to move. The movement of the first clamping plate 45 will drive the second shock-absorbing spring 47 to stretch, and the second shock-absorbing spring 47 absorbs and releases the kinetic energy;

[0037] Step 3: The swaying amplitude of the transformer body 1 is reduced by the damper 44, reducing the swaying amplitude of the transformer body 1 itself, so as to enhance the stability and safety of the transformer body 1 under extreme conditions such as earthquakes.

[0038] During the operation of this embodiment: when the transformer body 1 shakes itself, the kinetic energy between the bottom plate 41 and the top plate 42 is absorbed and released by the first shock-absorbing spring 43. When the transformer body 1 shakes left and right, the movement of the transformer body 1 will drive the movement of the first clamping plate 45, and the movement of the first clamping plate 45 will drive the stretching of the second shock-absorbing spring 47. The second shock-absorbing spring 47 absorbs and releases kinetic energy, and the damper 44 reduces the amplitude of the left and right shaking of the transformer body 1, reducing the shaking amplitude of the transformer body 1 itself, so as to enhance the stability and safety of the transformer body 1 under extreme conditions such as earthquakes. When the shaking amplitude of the transformer body 1 is too large, the downward movement of the transformer body 1 will drive the downward movement of the top plate 42. The downward movement of the top plate 42 will drive the downward movement of the reset telescopic rod 412. The downward movement of the reset telescopic rod 412 will drive the downward movement of the connecting plate 413. The downward movement of the connecting plate 413 will contact the transmission plate 411. The downward movement of the connecting plate 413 will drive the downward movement of the transmission plate 411. The downward movement of the transmission plate 411 will contact the arc-shaped panel 410. The downward movement of the transmission plate 411 will drive the transmission plate 411 to move to both sides. The movement of the transmission plate 411 to both sides will drive the second clamping plate 46 to move to both sides. The movement of the second clamping plate 46 to both sides will drive the slider 48 to move to both sides. The movement of the slider 48 to both sides will contact the inclined block 49. The movement of the slider 48 will be affected by the inclined block 49 and move upward. After the slider 48 moves upward, it will no longer contact the sliding groove. After the slider 48 no longer contacts the sliding groove, the second shock-absorbing spring 47 drives the second clamping plate 46 to move upward, so that the second shock-absorbing spring 47 no longer fixes and dampens the transformer body 1. When the vibration of the transformer body 1 is too strong, the transformer body 1 will move downward, and the downward movement of the transformer body 1 will lower the overall center of gravity of the device and improve the overall stability of the device.

[0039] Please refer to Figures 1 - 7 Based on the above embodiment, in another embodiment of the present invention, a buffer device and a stabilizing device are provided inside the protective shell 3. Among them, the buffer device includes: a hollow box 51, a friction block 52, an elastic telescopic rod 53, a limiting plate 54 and a brake lining 55. The hollow box 51 is fixedly installed at the bottom of the inner wall of the protective shell 3. The friction block 52 is fixedly installed on the side of the first clamping plate 45 away from the second clamping plate 46. The elastic telescopic rod 53 is fixedly installed at the bottom of the inner wall of the hollow box 51. The limiting plate 54 is fixedly installed at the top of the free end of the elastic telescopic rod 53. The brake lining 55 is slidably installed on the inner wall of the hollow box 51 to prevent the inertia from being too large when the weight of the transformer body 1 itself is large and it moves downward, resulting in the transformer body 1 colliding with the protective shell 3 and being damaged when moving downward.

[0040] A second spring is provided between the brake lining 55 and the hollow box 51. The brake lining 55 contacts the limiting plate 54, and the second spring drives the brake lining 55 to reset.

[0041] The buffer device further includes: a fixing plate 56, an L-shaped plate 57, a reset plate 58, a rotating plate 59, and a blocking plate 510. The fixing plate 56 is fixedly installed on the inner wall of the hollow box 51. The L-shaped plate 57 is rotatably installed between the fixing plates 56. The reset plate 58 is fixedly installed on the side of the friction block 52 close to the hollow box 51. The rotating plate 59 is rotatably installed at one end of the reset plate 58 close to the hollow box 51. The blocking plate 510 is fixedly installed at the bottom of the reset plate 58. When the device completes buffering, the upward movement of the transformer body 1 will drive the device to reset, reducing the work input during device maintenance and lowering the maintenance cost.

[0042] A first torsion spring is arranged between the L-shaped plate 57 and the fixing plate 56. The rotating plate 59 contacts the L-shaped plate 57, and the first torsion spring drives the L-shaped plate 57 to reset.

[0043] The stabilizing device includes: a vertical plate 61, a limiting ring 62, a square groove 63, a circular groove 64, a connecting rod 65, a tapered rod 66, and a spring plate 67. The vertical plate 61 is fixedly installed at the bottom of the inner wall of the protective shell 3. The limiting ring 62 is fixedly installed on the surface of the vertical plate 61. The square groove 63 is opened on the side of the hollow box 51 close to the vertical plate 61. The circular groove 64 is opened at the bottom of the protective shell 3. The connecting rod 65 is slidably installed on the inner wall of the square groove 63. One end of the connecting rod 65 is fixedly installed on the surface of the limiting plate 54. The tapered rod 66 is fixedly installed at the other end of the connecting rod 65. The overall stability of the device is improved by inserting the tapered rod 66 into the ground. The spring plate 67 is rotatably installed on the circumferential surface of the tapered rod 66, increasing the contact area between the tapered rod 66 and the ground and further improving the stability of the device.

[0044] A second torsion spring is arranged between the spring plate 67 and the tapered rod 66. The spring plate 67 contacts the limiting ring 62, and the second torsion spring drives the spring plate 67 to reset.

[0045] During the operation of this embodiment: When the first clamping plate 45 moves downward, it will drive the friction block 52 to move downward. When the friction block 52 moves downward, it will contact the brake lining 55. After the friction block 52 contacts the brake lining 55, the frictional force between the friction block 52 and the brake lining 55 will increase. After the frictional force between the friction block 52 and the brake lining 55 increases, the speed of the friction block 52 moving downward will decrease, so that the speed of the transformer body 1 moving downward will decrease, preventing the large inertia of the transformer body 1 moving downward due to its large own weight, resulting in the transformer body 1 colliding with the protective shell 3 and being damaged when moving downward. When the friction block 52 moves upward, it will drive the reset plate 58 to move upward. When the reset plate 58 moves upward, it will drive the rotating plate 59 to move upward. When the rotating plate 59 moves upward, it will contact the L-shaped plate 57. After the rotating plate 59 contacts the L-shaped plate 57, it will be blocked by the blocking plate 510, so that the rotating plate 59 cannot rotate downward. After the rotating plate 59 cannot rotate downward, it will drive the L-shaped plate 57 to rotate. When the L-shaped plate 57 rotates, it will drive the brake lining 55 to move in the direction of the friction block 52. After the brake lining 55 moves, it will drive the limit plate 54 to move upward through the reset of the elastic telescopic rod 53. When the limit plate 54 moves upward, it will re-limit the brake lining 55, so that when the device completes buffering, the upward movement of the transformer body 1 will drive the device to reset, reducing the work input during the maintenance of the device and lowering the maintenance cost.

[0046] When the limit plate 54 moves downward, it will drive the connecting rod 65 to move downward. When the connecting rod 65 moves downward, it will drive the tapered rod 66 to move downward. After the tapered rod 66 moves downward, it will pass through the circular groove 64. When the tapered rod 66 moves downward, it will be inserted into the ground. By inserting the tapered rod 66 into the ground, the overall stability of the device is improved. When the tapered rod 66 moves downward, it will drive the elastic plate 67 to move downward. After the elastic plate 67 moves downward, it will no longer contact the limit ring 62. After the elastic plate 67 no longer contacts the limit ring 62, the limit ring 62 will no longer limit the elastic plate 67. After the elastic plate 67 loses its limit, it will be reset by the second torsion spring and drive the elastic plate 67 to rotate away from the tapered rod 66. After the elastic plate 67 rotates, it will contact the ground, increasing the contact area between the tapered rod 66 and the ground and further improving the stability of the device.
