TECHNICAL FIELD
[0001] The application relates to the field of switch cabinet bases, in particular to a high-voltage switch cabinet installation base and a high-voltage switch cabinet installation method. BACKGROUND
[0002] The high-voltage switch cabinet is a device used in power generation, power transmission, power distribution, power conversion and consumption to perform functions such as switching, control or protection. In order to improve the stability of the high-voltage switch cabinet installation, a high-voltage switch cabinet installation base is usually required.
[0003] The existing patent (publication number: CN112864871A) discloses a high-voltage switch cabinet installation base and the switch cabinet, which comprises an installation base. The lower part of the installation base is buried below the ground. The inventor found that the following problems in the prior art have not been well solved in the process of implementing the scheme: 1. After the installation of the base of the high-voltage switch cabinet, only the vibration in the up-down direction of the high-voltage switch cabinet can be damped. Since there are small earthquakes in some areas from time to time, the base will shake in multiple directions at this time, which is easy to cause the high-voltage switch cabinet to overturn with the base, has poor stability, and has safety hazards.

[0014] The end of the rack away from the compression spring is designed as an arc-shaped surface, and the two transmission sleeves are symmetrically arranged at the same level.
[0015] Preferably, the pressure plate has a waist-shaped groove in the middle, and the inner top surface of the base is fixedly connected with a sliding pin that matches the waist-shaped groove;
[0016] The length of the waist-shaped groove is the same as the diameter of the turntable.
[0017] Preferably, the limiting mechanism includes guide grooves, and two guide grooves are provided. The two guide grooves are symmetrically opened on the inner bottom surface of the base. A trapezoidal limiting block is slidably connected between the two guide grooves. The side wall of the trapezoidal limiting block overlaps with one side of the adjusting mechanism, and the top of the trapezoidal limiting block overlaps with the bottom of the supporting mechanism.
[0018] The trapezoidal limiting block has guide rods fixedly connected symmetrically to its side wall. One end of the guide rod is movably inserted into the inside of the base. The side wall of the base has a circular hole, and the inner wall of the circular hole is fixedly connected to an electric push rod that cooperates with the trapezoidal limiting block.
[0019] Preferably, the bottom of the trapezoidal limiting block is rotatably connected to a roller, and the bottom surface of the roller overlaps with the inner bottom surface of the guide groove.
[0020] Preferably, the support mechanism includes a groove, which is formed at the bottom of the support base, and a support plate is movably connected inside the groove. The two sides of the bottom of the support plate respectively overlap the tops of the two limiting mechanisms.
[0021] The support plate has a guide hole in the middle, and a shock absorber rod is movably inserted into the guide hole. The bottom of the shock absorber rod is fixedly connected to the inner bottom surface of the base, and a ring is rotatably connected to the top of the shock absorber rod.

[0022] Preferably, arc-shaped limiting strips are fixedly connected to all four sides of the sidewall of the support plate, the sidewall of the arc-shaped limiting strip overlaps with the inner wall of the groove, and nineteen shock-absorbing rods are equidistantly distributed on both the front and rear sides of the support plate.
[0023] The bottom of the support plate is rotatably connected to a steel ball, and the bottom of the steel ball overlaps the top of the limiting mechanism.
[0024] A method for using a high-voltage switchgear mounting base includes the following steps:
[0025] S1. When in use, first place the switch cabinet body on top of the support base for installation and fixation, and at the same time fix the base on the ground. At this time, the bottom of the support base overlaps the top of multiple shock-absorbing rods and balls. Then, start the electric push rods on both sides of the base to extend the electric push rods and press against the two trapezoidal limit blocks to move relative to each other. As the trapezoidal limit blocks move, the two sides of the support plate slide on the inclined surfaces of the two trapezoidal limit blocks respectively. Then the support plate moves up into the groove, and the two trapezoidal limit blocks overlap on both sides of the bottom of the support plate to support and limit the bottom of the support base. Then start the electric telescopic rod to retract.
[0026] S2. When the ground vibrates, the base begins to shake. The positioning ring is always in the middle of the movable groove under the four spring telescopic rods. The support tube shakes synchronously with the base and presses the transmission sleeve and rack against the inner wall of the positioning ring. When the rack is pressed into the transmission groove, the rack meshes with the sprocket. At this time, the sprocket rotates the transmission rod and the turntable.
[0027] S3. When the rack moves to its limit position, the turntable rotates half a turn synchronously with the guide pin. The guide pin moves the waist-shaped strip from one side of the turntable to the other side, causing the waist-shaped strip to move the pressure plate towards the corresponding trapezoidal limit block. At the same time, the diamond plate rotates with the movement of the connecting rod and the waist-shaped strip, keeping the two pressure plates in a synchronous opposite-south state. This causes the trapezoidal limit block to be pressed and release its support on the support plate. The support plate slides down along the surface of the shock absorber rod and releases its support and limit on the support seat. At this time, the middle position of the bottom of the support seat only contacts the ball bearing at the top of the shock absorber rod. When the base shakes, the support seat will not shake synchronously due to the small contact area between the ball bearing and the support seat. At this time, the switch cabinet body will not produce violent shaking.
[0028] S4. After the earthquake ends, the base stops shaking. At this time, the spring telescopic rod presses the positioning ring back to the middle position of the movable groove, and the compressed spring pushes the rack back to its original position, causing the spur gear, transmission rod and turntable to reverse and push the waist-shaped strip and pressure plate back to their original positions. Then, the two electric push rods are activated to press the trapezoidal limit block to move relative to each other, causing the support plate to move up and cooperate with the trapezoidal limit block to support the middle position of the bottom of the support base.
[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0030] In this invention, through the coordinated use of components such as the support plate, trapezoidal limiting block, and shock absorber, during an earthquake, the base, along with the support tube and transmission sleeve, shakes, causing the rack to press against the inner wall of the positioning ring. At this time, the rack meshes with the spur gear. Under the action of the adjustment mechanism, the pressure plate moves and presses against the trapezoidal limiting block, the bottom of the support plate is released from restriction and moves downward. At this time, the support seat is released from the limiting state and engages with the ball bearings at the top of the shock absorber, so that the base will not cause violent shaking of the support seat during the shaking process, thus improving the stability of the switch cabinet body on top of the support seat.
[0031] In this invention, by using components such as diamond-shaped plates, connecting rods, and waist-shaped strips in combination, when the two pressure plates move with the two waist-shaped strips respectively, the two waist-shaped strips can achieve synchronous movement through the cooperation of the connecting rods and diamond-shaped plates, ensuring that the two trapezoidal limit blocks can move synchronously to release the support plate and improve the use effect.
[0032] In this invention, through the coordinated use of components such as spring telescopic rods, movable grooves, and positioning rings, after the earthquake stops, the four spring telescopic rods inside the movable groove can press the positioning ring to reset, causing the positioning ring to move to the axial position of the movable groove, thus achieving an automatic adjustment effect and facilitating the next use.

Detailed Implementation
[0043] 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.
[0044] Please see Figures 1 to 9This invention provides a technical solution: a high-voltage switchgear mounting base 1, including a base 1, a support seat 2 movably connected to the top of the base 1, and a switchgear body 3 fixedly mounted on the top of the support seat 2. It should be noted that: after the high-voltage switchgear body is placed on top of the support seat 2, it is installed and fixed by the fixing bolts around the support seat 2 and the threaded connection between the support seat 2 and the side wall of the high-voltage switchgear; the base 1 is also fixed to the ground by anchor bolts; steel balls are rotatably connected to the bottom of the support seat 2 around its perimeter, with the bottom of the steel balls resting on the top of the base 1. When the support seat 2 is released from its restrained state, the support seat 2 and the base 1 are in rolling friction contact, preventing the base 1 from violently shaking along with the support seat 2.
[0045] An adjustment mechanism 4 is movably connected to the lower part of the inner wall of the base 1. Two symmetrical movable connection limit mechanisms 5 are made to the inner wall of the base 1. The side walls of the two limit mechanisms 5 overlap with the two sides of the adjustment mechanism 4 respectively.
[0046] The inner bottom surface of the base 1 is provided with a support mechanism 6. The surface of the support mechanism 6 overlaps with the top of the limiting mechanism 5, and the top of the support mechanism 6 overlaps with the bottom of the support base 2.
[0047] In this embodiment, as Figures 1 to 9 As shown, the adjustment mechanism 4 includes two movable slots 401, which are symmetrically located at the bottom of the base 1. Spring telescopic rods 402 are fixedly connected to the inner walls of each movable slot 401, and positioning rings 403 overlap between the four spring telescopic rods 402. It should be noted that the end of the spring telescopic rod 402 near the positioning ring 403 is designed with an arc surface to reduce friction between the spring telescopic rod 402 and the positioning ring 403. Furthermore, the elasticity of the spring telescopic rod 402 is greater than that of the compression spring 411. When the support tube 405, carrying the rack 410, presses against the inner wall of the positioning ring 403, the compression spring 411 is compressed and contracts first. Only after the compression spring 411 has contracted to its limit position does the positioning ring 403 sway synchronously with the base 1.
[0048] The inner top surface of the movable groove 401 has an installation groove 404. A support tube 405 is fixedly connected to the inner wall of the installation groove 404. A transmission sleeve 406 is symmetrically fixedly sleeved on the lower part of the support tube 405. A transmission rod 407 is rotatably connected to the middle part of the support tube 405. A spur gear 408 is symmetrically fixedly sleeved on the lower part of the transmission rod 407. The two spur gears 408 are rotatably connected inside the two transmission sleeves 406 respectively. It should be noted that the transmission sleeve 406 has a through hole that mates with the transmission rod 407. A support bearing is fixedly connected to the upper part of the inner wall of the support tube 405. The transmission rod 407 is fixedly connected to the inner ring of the support bearing, ensuring that the transmission rod 407 rotates stably between the support tube 405 and the two transmission sleeves 406.
[0049] The inner wall of the transmission sleeve 406 is symmetrically provided with transmission grooves 409. A rack 410, which engages with the positioning ring 403, is slidably connected inside the transmission groove 409. The side wall of the rack 410 meshes with the side wall of the adjacent spur gear 408. A compression spring 411 is fixedly connected between one end of the rack 410 and the inner wall of the transmission groove 409. It should be noted that the racks 410 on the upper and lower transmission sleeves 406 are staggered and arranged in a cross shape. When the base 1, carrying the support tube 405, moves in any direction along with the transmission sleeve 406 and the rack 410, it can press against the corresponding positioning ring 403. At this time, the rack 410 is pressed into the transmission groove 409 and meshes with the spur gear 408.
[0050] The top of the transmission rod 407 is fixedly connected to the turntable 412 through the mounting groove 404. The top of the turntable 412 is fixedly connected to the guide pin 413. The middle of the guide pin 413 is slidably connected to the waist-shaped strip 414. It should be noted that the waist-shaped strip 414 has a strip groove in the middle, and the guide pin 413 is slidably connected inside the strip groove.
[0051] A support rod 415 is fixedly connected to the middle of the inner bottom surface of the base 1. A pad 416 is fixedly connected to the top of the support rod 415. A rhomboid plate 417 is rotatably connected to the middle of the support rod 415. Connecting rods 418 are hinged to both ends of the rhomboid plate 417. The two connecting rods 418 are respectively hinged to the side walls of the two waist-shaped strips 414. It should be noted that the pad 416 is designed to support the support plate 602 after it falls. When the left turntable 412 rotates counterclockwise with the corresponding transmission rod 407, and the right turntable 412 rotates clockwise with the corresponding transmission rod 407, the two pressure plates 419 move in opposite directions and press against the two trapezoidal limit blocks 502 respectively. During this process, through the cooperation of the rhomboid plate 417 and the two connecting rods 418, the movement of the two pressure plates 419 can be synchronized, ensuring that the trapezoidal limit blocks 502 release their support from the support plate 602 at the same time, thus improving the stability of use.
[0052] A pressure plate 419 is fixedly connected to the side of the waist-shaped strip 414 away from the connecting rod 418, and the side wall of the pressure plate 419 overlaps with the side wall of the adjacent limiting mechanism 5. It should be noted that the side wall of the pressure plate 419 overlaps with the side wall of the adjacent trapezoidal limiting block 502.
[0053] In this embodiment, as Figures 1 to 9 As shown, sliders are fixedly connected to both the top and bottom of the rack 410, and symmetrical grooves are provided on the inner wall of the transmission groove 409. The two sliders are slidably connected inside the two grooves respectively. It should be noted that when the rack 410 slides from one end of the transmission groove 409 to the other end, the spur gear 408 rotates the turntable 412 half a turn through the transmission rod 407.
[0054] The end of the rack 410 away from the compression spring 411 is designed as an arc-shaped surface, symmetrically arranged with the two horizontal transmission sleeves 406. It should be noted that: with this symmetrical arrangement, when the rack 410 inside the left transmission sleeve 406 meshes with the corresponding sprocket 408, the transmission rod 407 rotates counterclockwise; while when the rack 410 inside the right transmission sleeve 406 meshes with the corresponding sprocket 408, the transmission rod 407 rotates clockwise.
[0055] In this embodiment, as Figures 1 to 9 As shown, a waist-shaped groove is provided in the middle of the pressure plate 419, and a sliding pin that mates with the waist-shaped groove is fixedly connected to the inner top surface of the base 1. It should be noted that the stability of the movement of the pressure plate 419 and the waist-shaped strip 414 is improved by the cooperation of the sliding pin with the waist-shaped groove.
[0056] The length of the waist-shaped groove is the same as the diameter of the turntable 412. It should be noted that the diameter of the turntable 412 is set to 1.2 times the moving distance of the trapezoidal limit block 502 to avoid interference.
[0057] In this embodiment, as Figures 1 to 9 As shown, the limiting mechanism 5 includes two guide grooves 501, which are symmetrically arranged on the inner bottom surface of the base 1. A trapezoidal limiting block 502 is slidably connected between the two guide grooves 501. The side wall of the trapezoidal limiting block 502 overlaps with one side of the adjusting mechanism 4, and the top of the trapezoidal limiting block 502 overlaps with the bottom of the support mechanism 6. It should be noted that the top of the trapezoidal limiting block 502 overlaps with the bottom of the support plate 602, thus supporting the support plate 602.
[0058] A guide rod 503 is symmetrically fixedly connected to the side wall of the trapezoidal limiting block 502. One end of the guide rod 503 is movably inserted into the interior of the base 1. A circular hole 504 is provided on the side wall of the base 1, and an electric push rod 505 that cooperates with the trapezoidal limiting block 502 is fixedly connected to the inner wall of the circular hole 504. It should be noted that a guide groove is provided on the side wall of the base 1, and the guide rod 503 is movably inserted into the interior of the guide groove. The guide rod 503 is designed to improve the stability of the movement of the trapezoidal limiting block 502.
[0059] In this embodiment, as Figures 1 to 9 As shown, a roller is rotatably connected to the bottom of the trapezoidal limiting block 502, and the bottom surface of the roller overlaps with the inner bottom surface of the guide groove 501. It should be noted that this reduces the frictional resistance of the trapezoidal limiting block 502 during movement.
[0060] In this embodiment, as Figures 1 to 9As shown, the support mechanism 6 includes a groove 601, which is formed at the bottom of the support base 2. A support plate 602 is movably connected inside the groove 601, and the two sides of the bottom of the support plate 602 respectively overlap the tops of the two limiting mechanisms 5. It should be noted that when the support plate 602 is supported and restricted inside the groove 601 by the trapezoidal limiting plate 502, the support base 2 is in a limited state through the groove 601 at the bottom and the support plate 602 with the cooperation of the shock-absorbing rod 604. At this time, the support base 2 will not swing on the top of the base 1.
[0061] A guide hole 603 is provided in the middle of the support plate 602. A shock absorber rod 604 is movably inserted into the guide hole 603. The bottom of the shock absorber rod 604 is fixedly connected to the inner bottom surface of the base 1. A ring 605 is rotatably connected to the top of the shock absorber rod 604. A ball bearing 606 is rotatably connected to the top of the ring 605. The top of the ball bearing 606 overlaps the bottom of the support base 2. It should be noted that a connecting bearing is fixedly sleeved on the top of the shock absorber rod 604, and the bottom of the ring 605 is fixedly connected to the outer ring of the connecting bearing. The shock absorber rod 604 is existing technology and will not be described in detail. The top surface of the ball bearing 606 is flush with the top surface of the support plate 602.
[0062] In this embodiment, as Figures 1 to 9 As shown, arc-shaped limiting strips are fixedly connected to all four sides of the sidewall of the support plate 602. The sidewall of the arc-shaped limiting strip overlaps with the inner wall of the groove 601. Nineteen damping rods 604 are evenly distributed on both the front and rear sides of the support plate 602. It should be noted that the number of guide holes 603 and damping rods 604 are the same and correspond one-to-one. The arc-shaped limiting strips facilitate the positioning of the support plate 602 and the groove 601, making it easy for the support plate 602 to enter the groove 601. The number of damping rods 604 can be reasonably set according to actual needs. When the support plate 602 releases its support for the support seat 2, the multiple damping rods 604 can reduce the vertical sway of the support seat 2 during an earthquake.
[0063] A steel ball is rotatably connected to the bottom of the support plate 602, and the bottom of the steel ball overlaps the top of the limiting mechanism 5. It should be noted that the steel ball overlaps the top of the trapezoidal limiting block, and the steel ball is designed to reduce the frictional resistance between the trapezoidal limiting block 502 and the support plate 602 when the trapezoidal limiting block 502 moves.
[0064] In this embodiment, as Figures 1 to 9 As shown, a method for using a high-voltage switchgear mounting base includes the following steps:
[0065] S1. When in use, first place the switch cabinet 3 body on top of the support base 2 for installation and fixation, and at the same time fix the base 1 on the ground. At this time, the bottom of the support base 2 overlaps the top of multiple shock-absorbing rods 604 and ball bearings 606. Then, start the electric push rods 505 on both sides of the base 1, so that the electric push rods 505 extend and press against the two trapezoidal limit blocks 502 to move relative to each other. As the trapezoidal limit blocks 502 move, the two sides of the support plate 602 slide on the inclined surfaces of the two trapezoidal limit blocks 502 respectively. Then, the support plate 602 moves up into the groove 601, and the two trapezoidal limit blocks 502 overlap on both sides of the bottom of the support plate 602 respectively, supporting and limiting the bottom of the support base 2. Then start the electric telescopic rod to retract.
[0066] S2. When the ground vibrates, the base 1 begins to shake. The positioning ring 403 is always in the middle position of the movable groove 401 under the four spring telescopic rods 402. The support tube 405 shakes synchronously with the base 1 and causes the transmission sleeve 406 and the rack 410 to be pressed against the inner wall of the positioning ring 403. When the rack 410 is pressed into the transmission groove 409, the rack 410 meshes with the spur gear 408. At this time, the spur gear 408 causes the transmission rod 407 and the turntable 412 to rotate.
[0067] S3. When the rack 410 moves to its limit position, the turntable 412 rotates half a turn synchronously with the guide pin 413. The guide pin 413 moves the waist-shaped strip 414 from one side of the turntable 412 to the other side, so that the waist-shaped strip 414 moves the pressure plate 419 towards the corresponding trapezoidal limit block 502. At the same time, the diamond plate 417 rotates with the movement of the connecting rod 418 and the waist-shaped strip 414, so that the two pressure plates 419 keep moving synchronously in opposite directions. This causes the trapezoidal limit block 502 to be pressed and release the support plate 602. The support plate 602 slides down along the surface of the shock absorber 604 and releases the support and limit on the support seat 2. At this time, the middle position of the bottom of the support seat 2 only contacts the ball 606 at the top of the shock absorber 604. When the base 1 shakes, the support seat 2 will not shake synchronously because the contact area between the ball 606 and the support seat 2 is small. At this time, the switch cabinet body 3 will not shake violently.
[0068] S4. After the earthquake ends, the base 1 stops shaking. At this time, the spring telescopic rod 402 presses against the positioning ring 403 and resets to the middle position of the movable groove 401. The compression spring 411 resets the rack 410, causing the spur gear 408, transmission rod 407 and turntable 412 to reverse and reset the waist-shaped strip 414 and pressure plate 419. Then, the two electric push rods 505 are activated to press against the trapezoidal limit block 502 and move relative to each other, causing the support plate 602 to move upward and cooperate with the trapezoidal limit block 502 to support the middle position of the bottom of the support base 2.
[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
