Description

Technical Field

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

[0002] The seismic support structure and method of dry-type transformers are mainly intended to enhance the stability and safety of the transformer under extreme conditions such as earthquakes.

[0003] The patent with patent announcement number CN213242164U relates to a dry-type transformer with a seismic support structure, including a dry-type transformer body and a base; a fixed plate is fixedly connected to the bottom end of the dry-type transformer; a first groove is opened on the base; the fixed plate is connected to the inner side wall of the bottom end of the first groove through a seismic resistance mechanism; a group of second grooves are opened on the inner side wall of the bottom end of the first groove; the seismic resistance 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 fixed plate, and the bottom end is fixedly connected to the inner side wall of the bottom end of the first groove. The patent provides a dry-type transformer with a seismic support structure to solve the problem that the dry-type transformer usually needs to be installed on a supporting base, but the seismic resistance of the base is poor, resulting in the loosening of the internal coil of the dry-type transformer when it is shocked, resulting in safety problems in the use of the dry-type transformer and increasing the risk factor.

[0004] The above patent solves the problem that dry-type transformers usually need to be installed on a supporting base, but the base has poor seismic resistance, which causes the internal coil of the dry-type transformer to loosen when it is shaken, resulting in safety issues in the use of the dry-type transformer and increasing the risk factor. However, when the dry-type transformer encounters a strong vibration, the excessive weight of the transformer itself will increase its inertia during shaking, resulting in excessive kinetic energy when the transformer shakes to the bottom, causing damage and high maintenance costs. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a seismic support structure and method for a dry-type transformer, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-seismic support structure of a dry-type transformer, comprising 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; The protective device comprises: a bottom plate, a top plate, a shock absorbing spring 1, a damper, a clamping plate 1, a clamping plate 2, a shock absorbing spring 2, a slider, a slope block, a curved plate, a transmission plate, a resetting telescopic rod and a connecting plate, wherein the bottom plate is fixedly mounted on the bottom of the inner wall of the protective shell, the top plate is fixedly mounted on the bottom of the flat plate, the shock absorbing spring 1 is arranged between the bottom plate and the top plate, the damper is arranged between the top plate and the bottom plate, the clamping plate 1 is fixedly mounted on the bottom of the flat plate, a sliding groove is provided on the surface of the protective shell, the slider is slidably mounted on the inner wall of the sliding groove, the clamping plate 2 is fixedly mounted on the top of the slider, and the shock absorbing spring 2 is arranged on the clamping plate. The inclined block is fixedly mounted on the inner wall of the sliding groove between the first plate and the second plate, the arc plate is fixedly mounted on the side of the second plate close to the damper, the transmission plate is slidably mounted on the inner wall surface of the protective shell, the reset telescopic rod is fixedly mounted on the side of the top plate close to the sliding groove, one end of the connecting plate is fixedly mounted on the fixed end of the reset telescopic rod, and the other end of the connecting plate is slidably mounted on the inner wall of the protective shell. After the slider moves to the top, it no longer contacts the sliding groove. After the slider no longer contacts the sliding groove, the second plate is driven to move to the top by the second shock-absorbing spring, so that the second shock-absorbing spring no longer fixes and dampens the transformer body.

[0007] According to the above technical solution, the sliding block contacts the inclined plane block, and a No. 1 spring is arranged between the transmission plate and the protective shell, and the transmission plate is driven to reset by the No. 1 spring.

[0008] According to the above technical solution, the buffer device includes: a hollow box, a friction block, an elastic telescopic rod, a limit plate and a brake pad. The hollow box is fixedly mounted on the bottom of the inner wall of the protective shell, the friction block is fixedly mounted on the side of the first clamping plate away from the second clamping plate, the elastic telescopic rod is fixedly mounted on the bottom of the inner wall of the hollow box, the limit plate is fixedly mounted on the top of the free end of the elastic telescopic rod, and the brake pad is slidably mounted on the inner wall of the hollow box. After the friction block contacts the brake pad, the friction force between the friction block and the brake pad increases. After the friction force between the friction block and the brake pad increases, the speed of the friction block when moving toward the bottom is reduced, so that the speed of the transformer body when moving toward the bottom is reduced.

[0009] According to the above technical solution, a No. 2 spring is arranged between the brake pad and the hollow box, the brake pad is in contact with the limit plate, and the No. 2 spring drives the brake pad to reset.

[0010] According to the above technical solution, the buffer device also includes: a fixed plate, an L-shaped plate, a reset plate, a rotating plate and a blocking plate. The fixed plate is fixedly installed on the inner wall of the hollow box, the L-shaped plate is rotatably installed between the fixed plates, the reset plate is fixedly installed on a side of the friction block close to the hollow box, the rotating plate is rotatably installed on an end of the reset plate close to the hollow box, and the blocking plate is fixedly installed on the bottom of the reset plate. When the rotating plate cannot rotate to the bottom, it will drive the L-shaped plate to rotate. The rotation of the L-shaped plate will drive the brake pad to move in the direction of the friction block. After the brake pad moves, it is reset by the elastic telescopic rod to drive the limit plate to move to the top. The movement of the limit plate to the top will re-limit the brake pad.

[0011] According to the above technical solution, a No. 1 torsion spring is arranged between the L-shaped plate and the fixed plate, and the rotating plate contacts the L-shaped plate, and the No. 1 torsion spring drives the L-shaped plate to reset.

[0012] 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 conical rod and a spring plate. The vertical plate is fixedly installed on 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 arranged on one side of the hollow box close to the vertical plate, the circular groove is arranged on the bottom of the protective shell, the connecting rod is slidably installed on the inner wall of the square groove, one end of the connecting rod is fixedly installed on the surface of the limiting plate, the conical rod is fixedly installed on the other end of the connecting rod, and the spring plate is rotatably installed on the circumferential surface of the conical rod. After the spring plate loses its limit, the spring plate is driven to rotate in a direction away from the conical rod by the No. 2 torsion spring reset, and the spring plate will contact the ground after rotation.

[0013] According to the above technical solution, a No. 2 torsion spring is arranged between the spring plate and the conical rod, the spring plate is in contact with the limiting ring, and the No. 2 torsion spring drives the spring plate to reset.

[0014] A method for using a seismic support structure of a dry-type transformer comprises the following steps: 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 shock absorbing spring 1; Step 2: When the transformer body is shaken left and right, the movement of the transformer body will drive the movement of the clamping plate 1, and the movement of the clamping plate 1 will drive the shock-absorbing spring 2 to stretch, and the shock-absorbing spring 2 absorbs kinetic energy and releases it; Step 3: Use the damper to reduce the left and right shaking amplitude of the transformer body, reduce the shaking amplitude of the transformer body itself, and enhance the stability and safety of the transformer body under extreme conditions such as earthquakes.

[0015] The present invention provides a seismic support structure and method for a dry-type transformer, which has the following beneficial effects: (1) This invention reduces the left-right swaying amplitude of the transformer body through a damper, thereby reducing the swaying amplitude of the transformer body itself, thereby enhancing the stability and safety of the transformer body under extreme conditions such as earthquakes. The second clamping plate is driven to move toward the top by the second shock-absorbing spring, so that the second shock-absorbing spring no longer fixes and dampens the transformer body. When the transformer body vibrates too strongly, the transformer body will move toward the bottom. The movement of the transformer body toward the bottom will lower the overall center of gravity of the device and improve the overall stability of the device.

[0016] (2) The invention reduces the speed of the friction block when it moves toward the bottom by increasing the friction force between the friction block and the brake pad, thereby reducing the speed of the transformer body when it moves toward the bottom, thereby preventing the transformer body from colliding with the protective shell and being damaged when it moves toward the bottom due to the large inertia caused by the large weight of the transformer body itself. The brake pad is re-positioned by moving the limit plate toward the top, so that when the device completes buffering, the transformer body moves toward the top to drive the device to reset, thereby reducing the work input during maintenance of the device and reducing maintenance costs.

[0017] (3) In the present invention, the conical rod moves toward the bottom and is inserted into the ground. The insertion of the conical rod into the ground improves the overall stability of the device. The No. 2 torsion spring is reset to drive the spring plate to rotate in the direction away from the conical rod. After the spring plate rotates, it will contact the ground, increasing the contact area between the conical rod and the ground, further improving the stability of the device.

The inclined block 49 is fixedly installed on the inner wall of the sliding groove, the arc 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 on the fixed end of the reset telescopic rod 412, and 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 to the bottom, and the movement of the transformer body 1 to the bottom will lower the overall center of gravity of the device and improve the overall stability of the device.

[0022] The slider 48 contacts the inclined surface block 49 , and a No. 1 spring is arranged between the transmission plate 411 and the protective shell 3 , and the transmission plate 411 is driven to reset by the No. 1 spring.

[0023] A method for using a seismic support structure of a dry-type transformer comprises the following steps: Step 1: When the transformer body 1 itself shakes, the kinetic energy between the bottom plate 41 and the top plate 42 is absorbed and released by the shock absorbing spring 1 43; Step 2: When the transformer body 1 is shaken left and right, the movement of the transformer body 1 drives the clamping plate 1 45 to move, and the movement of the clamping plate 1 45 drives the shock absorbing spring 2 47 to stretch, and the shock absorbing spring 2 47 absorbs kinetic energy and releases it; Step 3: The amplitude of the left-right shaking of the transformer body 1 is reduced by the damper 44, and the shaking amplitude of the transformer body 1 itself is reduced, so as to enhance the stability and safety of the transformer body 1 under extreme conditions such as earthquakes.

[0024] When the present embodiment is working: when the transformer body 1 itself shakes, the kinetic energy between the bottom plate 41 and the top plate 42 is absorbed and released through the shock-absorbing spring 1 43; when the transformer body 1 shakes left and right, the movement of the transformer body 1 will drive the clamping plate 1 45 to move; the movement of the clamping plate 1 45 will drive the shock-absorbing spring 2 47 to stretch; the shock-absorbing spring 2 47 absorbs the kinetic energy and releases it; the amplitude of the left and right shaking of the transformer body 1 is reduced by the damper 44, and the shaking amplitude of the transformer body 1 itself is reduced, so as to enhance the stability and safety of the transformer body 1 under extreme conditions such as earthquakes; when the amplitude of the shaking of the transformer body 1 is too large, the movement of the transformer body 1 toward the bottom will drive the top plate 42 to move toward the bottom; the movement of the top plate 42 toward the bottom will drive the reset telescopic rod 412 to move toward the bottom; the movement of the reset telescopic rod 412 toward the bottom will drive the connecting plate 413 to move toward the bottom; the movement of the connecting plate 413 toward the bottom will contact the transmission plate 411, and the connecting plate The movement of 413 toward the bottom will drive the transmission plate 411 to move toward the bottom, and the movement of the transmission plate 411 toward the bottom will contact the arc panel 410. The movement of the transmission plate 411 toward the bottom 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 surface block 49. The movement of the slider 48 will be affected by the inclined surface block 49 and move toward the top. After the slider 48 moves toward the top, it no longer contacts the sliding groove. After the slider 48 no longer contacts the sliding groove, the second clamping plate 46 is driven to move toward the top by the second shock-absorbing spring 47, so that the second shock-absorbing spring 47 no longer fixes and dampens the transformer body 1, so that when the vibration of the transformer body 1 is too strong, the transformer body 1 will move toward the bottom. The movement of the transformer body 1 to the bottom will lower the overall center of gravity of the device and improve the overall stability of the device.

[0025] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a buffer device and a stabilizing device are arranged inside the protective shell 3, wherein the buffer device comprises: a hollow box 51, a friction block 52, an elastic telescopic rod 53, a limit plate 54 and a brake pad 55, the hollow box 51 is fixedly mounted on the bottom of the inner wall of the protective shell 3, the friction block 52 is fixedly mounted on the side of the clamping plate 1 45 away from the clamping plate 2 46, the elastic telescopic rod 53 is fixedly mounted on the bottom of the inner wall of the hollow box 51, the limit plate 54 is fixedly mounted on the top of the free end of the elastic telescopic rod 53, and the brake pad 55 is slidably mounted on the inner wall of the hollow box 51 to prevent the transformer body 1 from having a large weight and a large inertia when moving toward the bottom, resulting in the transformer body 1 colliding with the protective shell 3 when moving toward the bottom and being damaged.

[0026] A second spring is provided between the brake pad 55 and the hollow box 51 . The brake pad 55 contacts the limit plate 54 , and the brake pad 55 is reset by the second spring.

[0027] The buffer device also includes: a fixed plate 56, an L-shaped plate 57, a reset plate 58, a rotating plate 59 and a blocking plate 510. The fixed plate 56 is fixedly installed on the inner wall of the hollow box 51, the L-shaped plate 57 is rotatably installed between the fixed plates 56, the reset plate 58 is fixedly installed on a side of the friction block 52 close to the hollow box 51, the rotating plate 59 is rotatably installed on one end of the reset plate 58 close to the hollow box 51, and the blocking plate 510 is fixedly installed on the bottom of the reset plate 58, so that when the device completes buffering, the transformer body 1 moves toward the top to drive the device to reset, thereby reducing the work input of the device during maintenance and reducing the maintenance cost.

[0028] A torsion spring No. 1 is arranged between the L-shaped plate 57 and the fixed plate 56. The rotating plate 59 contacts the L-shaped plate 57, and the L-shaped plate 57 is driven to reset by the torsion spring No. 1.

[0029] 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 conical rod 66 and a spring plate 67. The vertical plate 61 is fixedly installed on 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 arranged on a side of the hollow box 51 close to the vertical plate 61, the circular groove 64 is arranged on 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, and the conical rod 66 is fixedly installed on the other end of the connecting rod 65. The overall stability of the device is improved by inserting the conical rod 66 into the ground. The spring plate 67 is rotatably installed on the circumferential surface of the conical rod 66 to increase the contact area between the conical rod 66 and the ground, thereby further improving the stability of the device.

[0030] A second torsion spring is provided between the spring plate 67 and the conical rod 66 . The spring plate 67 contacts the limiting ring 62 , and the spring plate 67 is driven to reset by the second torsion spring.

[0031] When the present embodiment is working, the movement of the clamping plate 45 toward the bottom will drive the friction block 52 toward the bottom, and the movement of the friction block 52 toward the bottom will contact the brake pad 55. After the friction block 52 contacts the brake pad 55, the friction force between the friction block 52 and the brake pad 55 will increase. After the friction force between the friction block 52 and the brake pad 55 increases, the speed of the friction block 52 when moving toward the bottom is reduced, so that the speed of the transformer body 1 when moving toward the bottom is reduced, so as to prevent the transformer body 1 from colliding with the protective shell 3 when moving toward the bottom due to the large weight of the transformer body 1 itself. The friction block 52 moves toward the top and drives the reset plate 58 to move toward the top. The reset plate 58 moves toward the top The movement of the top will drive the rotating plate 59 to move toward the top, and the rotating plate 59 moving toward the top will contact with the L-shaped plate 57. After the rotating plate 59 contacts with the L-shaped plate 57, it is blocked by the blocking plate 510, so that the rotating plate 59 cannot rotate toward the bottom. After the rotating plate 59 cannot rotate toward the bottom, it will drive the L-shaped plate 57 to rotate. The rotation of the L-shaped plate 57 will drive the brake pad 55 to move in the direction of the friction block 52. After the brake pad 55 moves, it will reset through the elastic telescopic rod 53 and drive the limit plate 54 to move toward the top. The movement of the limit plate 54 toward the top will re-limit the brake pad 55, so that when the device completes buffering, the movement of the transformer body 1 toward the top will drive the device to reset, thereby reducing the work input of the device during maintenance and reducing the maintenance cost.

[0032] The movement of the limit plate 54 toward the bottom will drive the connecting rod 65 toward the bottom, and the movement of the connecting rod 65 toward the bottom will drive the tapered rod 66 toward the bottom. After the tapered rod 66 moves toward the bottom, it will pass through the circular groove 64. The tapered rod 66 moves toward the bottom and is inserted into the ground. The overall stability of the device is improved by inserting the tapered rod 66 into the ground. The movement of the tapered rod 66 toward the bottom will drive the spring plate 67 to move toward the bottom. After the spring plate 67 moves to the bottom, it no longer contacts the limit ring 62. After the spring plate 67 no longer contacts the limit ring 62, the limit ring 62 no longer limits the spring plate 67. After the spring plate 67 loses its limit, the No. 2 torsion spring is used to reset and drive the spring plate 67 to rotate in the direction away from the tapered rod 66. After the spring plate 67 rotates, it will contact the ground, thereby increasing the contact area between the tapered rod 66 and the ground, further improving the stability of the device.
