Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for high and low voltage switchgear, specifically a reinforcement device for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is an important piece of equipment in power systems, mainly used for power distribution, control, and protection. During actual installation and use, switchgear typically needs to be fixed in a designated location to ensure operational stability.

[0003] Currently, most common switchgear reinforcement methods on the market involve directly connecting the cabinet to the ground or support with bolts. This method has the following drawbacks: traditional reinforcement structures are mostly fixed-size designs, unable to be adjusted for different switchgear specifications. When replacing or upgrading the switchgear, the reinforcement structure must be replaced, increasing operating costs and operational difficulty. Furthermore, fixing only with bottom bolts leaves the cabinet's side walls without effective support, making it prone to tilting and shaking under external impacts or ground vibrations, potentially leading to poor contact of internal electrical components and affecting the normal operation of the power system. Traditional reinforcement methods require manual tightening of bolts one by one, resulting in low installation efficiency, and subsequent maintenance or disassembly also requires significant time. Therefore, those skilled in the art have proposed a reinforcement device for high and low voltage switchgear to address the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforcement device for high and low voltage switchgear to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A reinforcement device for high and low voltage switchgear includes a support base and a support disc. The support disc is fixedly connected to the top surface of the support base. A lower reinforcement component and an upper reinforcement component are connected to the support base. The lower reinforcement component is used to fix the four corners of the cabinet at the bottom, and the upper reinforcement component is used to fix the side wall of the cabinet and can be adjusted at any height.

[0006] As a further embodiment of the present invention: the lower reinforcement component includes a mounting groove, a bidirectional threaded rod, a lower threaded plate, a drive motor, a transmission wheel, and a transmission belt. The support base has a mounting groove inside, and two sets of parallel bidirectional threaded rods are rotatably connected in the mounting groove. One end of the bidirectional threaded rod extends to the outside of the support base and is fixedly connected to a transmission wheel. The transmission wheels are connected to each other by a transmission belt. One set of transmission wheels is fixedly connected to the output shaft of the drive motor. A lower threaded plate is threadedly connected to one side of the same threaded section of the bidirectional threaded rod.

[0007] As a further embodiment of the present invention: the lower reinforcement component also includes a first sliding vertical rod, a first sliding groove, a sliding plate and a sliding guide rail. The first sliding vertical rod is fixedly connected to both the front and rear sides of the top surface of the lower threaded plate. The first sliding groove is opened on both the front and rear sides of the top surface of the support base and is fixedly connected to the sliding guide rail. The upper end of the first sliding vertical rod located on the same side passes through the first sliding groove and is fixedly connected to the sliding plate. The sliding plate is slidably connected to the sliding guide rail.

[0008] As a further embodiment of the present invention: the lower reinforcement component also includes a reinforcement box, a double-headed cylinder, a second sliding vertical rod, a second sliding groove, and a right-angle plate. The top surface of each sliding plate is fixedly connected to the reinforcement box, and the double-headed cylinder is fixedly connected inside each reinforcement box. The ends of the two piston rods of the double-headed cylinder are fixedly connected to the second sliding vertical rod. The top surface of the reinforcement box is provided with a second sliding groove. The upper end of the second sliding vertical rod passes through the second sliding groove and is fixedly connected to a right-angle plate arranged symmetrically. The inner side of the right-angle plate is adapted to the outer wall of the four corners below the cabinet.

[0009] As a further embodiment of the present invention: the upper reinforcement component includes a reinforcement screw, a reinforcement slide rod, an upper threaded plate and a limiting block. The two front corners of the top surface of the support base are rotatably connected to the reinforcement screw, and the two rear corners of the top surface of the support base are fixedly connected to the reinforcement slide rod. The upper threaded plate is threadedly connected to the reinforcement screw, and the upper threaded plate is simultaneously slidably connected to the reinforcement slide rod located on the same side. The upper end of the reinforcement screw is fixedly connected to the limiting block.

[0010] As a further embodiment of the present invention: the upper reinforcement component also includes a dual-axis motor, a drive crossbar, a first bevel gear and a second bevel gear. The dual-axis motor is fixedly connected to the top surface of the support base. The two output shafts of the dual-axis motor are fixedly connected to the drive crossbar. The front end of the drive crossbar is fixedly connected to the first bevel gear. The second bevel gear is fixedly connected to the reinforcement screw. The first bevel gear and the second bevel gear located on the same side mesh with each other.

[0011] As a further embodiment of the present invention: the upper reinforcement assembly also includes a reinforcement cylinder, a connecting plate, a connecting spring, a connecting telescopic rod and a reinforcement plate. The outer side of the upper threaded plate is fixedly connected to the reinforcement cylinder. The piston rod end of the reinforcement cylinder passes through the upper threaded plate and is fixedly connected to the connecting plate. Several sets of connecting springs and connecting telescopic rods are fixedly connected to the side of the connecting plate. The other end of the connecting springs and connecting telescopic rods is fixedly connected to the reinforcement plate.

[0012] Compared with existing technologies, the advantages of this invention are as follows: The lower reinforcement component of this device can drive the right-angle plate to move laterally via a bidirectional threaded rod, adapting to switch cabinets of different widths; the upper reinforcement component can drive the upper threaded plate to move up and down via a dual-axis motor, adapting to switch cabinets of different heights, eliminating the need to replace the reinforcement structure due to changes in cabinet specifications, thus reducing operating costs. The lower reinforcement component fixes the four corners of the cabinet bottom, while the upper reinforcement component fixes the side walls of the cabinet, forming a double-fixation structure that effectively improves the cabinet's resistance to impact and vibration, preventing tilting or shaking. The reinforcement action is achieved through automated components such as drive motors, dual-axis motors, and cylinders, eliminating the need for manual adjustment, significantly improving installation and disassembly efficiency, and reducing the labor intensity of operators. The right-angle plate fits snugly against the cabinet, further enhancing the fixing effect. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0022] Please see Figure 1-4 A reinforcement device for high and low voltage switchgear includes a support base 1 and a support disc 2. The support disc 2 is fixedly connected to the top surface of the support base 1. A lower reinforcement component 3 and an upper reinforcement component 4 are connected to the support base 1. The lower reinforcement component 3 is used to fix the four corners of the cabinet at the bottom, and the upper reinforcement component 4 is used to fix the side wall of the cabinet and can be adjusted at any height.

[0023] The lower reinforcement component 3 includes a mounting groove 301, a bidirectional threaded rod 302, a lower threaded plate 303, a drive motor 304, a transmission wheel 305, and a transmission belt 306. The support base 1 has a mounting groove 301 inside. Two sets of parallel bidirectional threaded rods 302 are rotatably connected in the mounting groove 301. One end of the bidirectional threaded rod 302 extends to the outside of the support base 1 and is fixedly connected to the transmission wheel 305. The transmission wheels 305 are connected to each other by the transmission belt 306. One set of transmission wheels 305 is fixedly connected to the output shaft of the drive motor 304. The lower threaded plate 303 is threadedly connected to one side of the same threaded section of the bidirectional threaded rod 302.

[0024] The lower reinforcement component 3 also includes a first sliding vertical rod 307, a first sliding groove 308, a sliding plate 309, and a sliding guide rail 310. The first sliding vertical rod 307 is fixedly connected to both the front and rear sides of the top surface of the lower threaded plate 303. The first sliding groove 308 is opened on both the front and rear sides of the top surface of the support base 1 and is fixedly connected to the sliding guide rail 310. The upper end of the first sliding vertical rod 307 located on the same side passes through the first sliding groove 308 and is fixedly connected to the sliding plate 309. The sliding plate 309 is slidably connected to the sliding guide rail 310.

[0025] The lower reinforcement component 3 also includes a reinforcement box 311, a double-headed cylinder 312, a second sliding vertical rod 313, a second sliding groove 314, and a right-angle plate 315. The top surface of the sliding plate 309 is fixedly connected to the reinforcement box 311. The double-headed cylinder 312 is fixedly connected inside the reinforcement box 311. The two piston rod ends of the double-headed cylinder 312 are fixedly connected to the second sliding vertical rod 313. The top surface of the reinforcement box 311 is provided with a second sliding groove 314. The upper end of the second sliding vertical rod 313 passes through the second sliding groove 314 and is fixedly connected to a right-angle plate 315 arranged symmetrically. The inner side of the right-angle plate 315 is adapted to the outer wall of the four corners below the cabinet.

[0026] The switch cabinet to be reinforced is hoisted and placed on the support disc 2 of the support base 1. The drive motor 304 is started, which drives the two bidirectional threaded rods 302 to rotate synchronously through the transmission wheel 305 and the transmission belt 306. Since the lower threaded plates 303 connected to the threads on the bidirectional threaded rods 302 are located in the same direction of the thread, the synchronous rotation of the two rods will drive the four lower threaded plates 303 to move towards or away from each other in pairs. This will drive the four sliding plates 309 to move along the sliding guide rail 310 through the first sliding vertical rod 307 until the reinforcement boxes 311 on the sliding plates 309 move to the outer positions of the four corners below the cabinet. Then, the double-headed cylinders 312 in the four reinforcement boxes 311 are started at the same time, which drives the second sliding vertical rod 313 to move towards the middle along the second sliding groove 314, thereby driving the two sets of right-angle plates 315 to move closer to each other. When the inner side of the right-angle plate 315 is tightly attached to the outer wall of the four corners below the cabinet, the double-headed cylinders 312 are closed. At this point, the right-angle plate 315 clamps and fixes the four corners of the cabinet at the bottom, and together with the support disc 2, it supports the center of the bottom of the cabinet, thus achieving full fixation of the bottom of the cabinet. Example

[0027] This embodiment adds the following improvements based on Embodiment 1: The upper reinforcement component 4 includes a reinforcement screw 401, a reinforcement slide rod 402, an upper threaded plate 403, and a limiting block 404. The two front corners of the top surface of the support base 1 are rotatably connected to the reinforcement screw 401, and the two rear corners of the top surface of the support base 1 are fixedly connected to the reinforcement slide rod 402. The upper threaded plate 403 is threadedly connected to the reinforcement screw 401, and the upper threaded plate 403 is slidably connected to the reinforcement slide rod 402 located on the same side. The upper end of the reinforcement screw 401 is fixedly connected to the limiting block 404.

[0028] The upper reinforcement component 4 also includes a dual-axis motor 405, a drive crossbar 406, a first bevel gear 407 and a second bevel gear 408. The dual-axis motor 405 is fixedly connected to the top surface of the support base 1. The two output shafts of the dual-axis motor 405 are fixedly connected to the drive crossbar 406. The front end of the drive crossbar 406 is fixedly connected to the first bevel gear 407. The second bevel gear 408 is fixedly connected to the reinforcement screw 401. The first bevel gear 407 and the second bevel gear 408, which are located on the same side, mesh with each other.

[0029] Based on the height of the high and low voltage switchgear, the dual-axis motor 405 is started. The two output shafts of the dual-axis motor 405 drive the drive crossbar 406 to rotate, which in turn drives the first bevel gear 407 at its front end to rotate. Since the first bevel gear 407 meshes with the second bevel gear 408, the first bevel gear 407 drives the second bevel gear 408 to rotate, which in turn drives the reinforcing screw 401 to rotate. The upper threaded plate 403 is threadedly connected to the reinforcing screw 401. Under the restriction of the reinforcing slide rod 402, the upper threaded plate 403 cannot adjust the rotation direction of the dual-axis motor 405 with the reinforcing screw 401 to move up or down along the reinforcing screw 401 and the reinforcing slide rod 402 until the upper threaded plate 403 moves to a suitable reinforcing height on the side wall of the cabinet. It can only move up and down along the axial direction of the reinforcing screw 401 and the length direction of the reinforcing slide rod 402.

[0030] The upper reinforcement assembly 4 also includes a reinforcement cylinder 409, a connecting plate 410, a connecting spring 411, a connecting telescopic rod 412, and a reinforcement plate 413. The reinforcement cylinder 409 is fixedly connected to the outer side of the upper threaded plate 403. The piston rod end of the reinforcement cylinder 409 passes through the upper threaded plate 403 and is fixedly connected to the connecting plate 410. Several sets of connecting springs 411 and connecting telescopic rods 412 are fixedly connected to the side of the connecting plate 410. The other end of the connecting springs 411 and connecting telescopic rods 412 is fixedly connected to the reinforcement plate 413.

[0031] When the reinforcing cylinder 409 is activated, its piston rod extends, pushing the connecting plate 410 towards the side wall of the cabinet. The connecting plate 410 then moves the connecting spring 411, the connecting telescopic rod 412, and the reinforcing plate 413 synchronously. Once the reinforcing plate 413 contacts the side wall of the cabinet, the reinforcing cylinder 409 continues to push the connecting plate 410. At this point, the connecting spring 411 is compressed, generating an elastic reaction force. This ensures a secure fixation while preventing excessive pressure from damaging the cabinet.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
