Description

Technical Field

[0001] This application relates to the field of distribution cabinets, and more specifically, to a suspended high-voltage distribution cabinet. Background Technology

[0002] Suspended high-voltage switchgear is an electrical device suitable for 10kV and below high-voltage power distribution systems. Its cabinet is suspended from a wall or frame via brackets or rails, featuring a compact structure and small footprint. Internally, it integrates core components such as high-voltage circuit breakers, disconnect switches, and instrument transformers. It is primarily used for high-voltage circuit on / off control, overload and short-circuit protection, and power distribution, and is widely used in power distribution terminals or branch circuits in industrial and mining enterprises, high-rise buildings, and other locations.

[0003] Chinese patent application number 201921229532.7 discloses a suspended distribution cabinet, including a cabinet body and a cabinet suspension device disposed on the rear side of the cabinet body. The cabinet suspension device includes a mounting base and a hanging frame mounted on the mounting base. The mounting base includes a mounting plate and a hanging rod fixed on the mounting plate, the extension direction of the hanging rod being the same as the extension direction of the mounting plate. The hanging frame includes a hanging body in the shape of channel steel or angle steel and one or more downwardly bent hooks disposed on the upper part of the hanging body. The hanging body has several mounting holes that pass through the hanging body in the front-to-back direction. In use, the mounting base is first fixed to the wall, the hanging frame is fixed to the rear panel of the distribution cabinet, and then a single person can lift the distribution cabinet and hang the hanging frame on the hanging rod to achieve the suspended installation of the distribution cabinet. This utility model is simple to operate, convenient to install, and reliable to fix.

[0004] The above solution has the following shortcomings: When in use, the mounting base and the hanging bracket are fixed in advance, and then the distribution cabinet is lifted by manpower to hang the hanging bracket on the hanging rod. However, when the distribution cabinet is installed in a high position, the maintenance personnel need to use ladders and other tools to climb to the high position to operate, which poses a certain safety risk and reduces the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a suspended high-voltage distribution cabinet, which aims to improve the safety risks associated with working at heights and reduce the practicality of the device.

[0006] This application provides a suspended high-voltage switchgear, including a high-voltage switchgear cabinet. A support component is provided on the rear side of the high-voltage switchgear cabinet to guide it. A conductive connecting frame is installed on the back of the high-voltage switchgear cabinet. The conductive connecting frame is slidably connected to the inside of the support component. An installation plate is provided inside the support component. A traction mechanism is threaded on the back of the installation plate. The traction mechanism is used to pull the conductive connecting frame to move up and down. The traction mechanism includes a steel wire rope for connecting the conductive connecting frame and a winding box for winding the steel wire rope.

[0007] In one specific implementation, a take-up shaft is rotatably connected inside the take-up box, and a drive motor for driving the take-up shaft to rotate is mounted on the side of the take-up box.

[0008] In the above implementation process, by setting up a drive motor, the winding shaft inside the winding box can wind up the steel wire rope, thereby achieving the purpose of adjusting the vertical displacement.

[0009] In one specific implementation, a locking mechanism for locking the position of the conductive connecting frame is also installed on the back of the mounting plate. The locking mechanism includes an adjusting motor installed on the back of the mounting plate, wherein the output end of the adjusting motor is disposed on an adjusting shaft, and a first limiting block is welded to the surface of the adjusting shaft. The locking mechanism also includes a cylinder installed on the back of the mounting plate, wherein a telescopic rod is movable on one side of the cylinder, and a support plate is installed at the extended end of the telescopic rod.

[0010] In the above implementation process, by setting a locking mechanism, the transmission connection frame can be stably locked when suspended at the highest point, thereby improving the stability of the suspension and preventing loosening and falling during long-term suspension.

[0011] In one specific implementation, a corner bracket is welded to the back of the high-voltage distribution cabinet, wherein the high-voltage distribution cabinet is threaded onto the surface of the conductive connection frame via the corner bracket. A wire rope connecting block and a second limiting block for abutting and limiting against the first limiting block are provided on the back of the conductive connection frame, and conductive rollers are rotatably connected to the side of the conductive connection frame.

[0012] In the above implementation process, by setting up corner brackets and transmission rollers, the transmission connection frame can be installed and connected to the high-voltage distribution cabinet and the load-bearing components, which facilitates subsequent disassembly and maintenance and improves convenience.

[0013] In one specific implementation, the inner side of the bearing component is provided with a slide rail for guiding the movement of the rollers.

[0014] In the above implementation process, by setting up a slide rail, the transmission connection frame can be moved up and down by the transmission rollers.

[0015] In one specific implementation, a control switch for controlling the drive motor, the regulating motor, and the cylinder is fixedly connected inside the side wall of the bearing assembly.

[0016] In the above implementation process, it is convenient for staff to control the raising and lowering of the device by controlling the switch, and to lock the suspended state after the device is raised.

[0017] In one specific implementation, the surface of the mounting plate is provided with two sets of through holes, wherein the first limiting block extends into the inside of one set of through holes when locked, and the first limiting block is flush with the back of the mounting plate when unlocked, and the steel wire rope passes through the other set of through holes to the front of the mounting plate.

[0018] In the above implementation process, two sets of through holes are provided to facilitate the wire rope to be inserted to the front to pull the transmission connection frame, and also to facilitate locking and unlocking, thereby improving the usage effect.

[0019] In one specific implementation, when the first limiting block is in the locked state, the bottom surface of the first limiting block is flush with the top surface of the tray.

[0020] In the above implementation process, by making the bottom surface of the limiting block flush with the top surface of the support plate, the first limiting block can be auxiliaryly supported by the support plate when it is in the locked state, thus preventing the locked state from loosening.

[0021] In one specific implementation, the top and bottom sides of the load-bearing component are welded with fixing plates, wherein the surfaces of the fixing plates are provided with bolt holes for fixing to the ground and the wall.

[0022] In the above implementation process, fixing plates are provided on both the top and bottom sides to facilitate the fixed support of the load-bearing components and improve the stability of the device.

[0023] In one specific implementation, the outer surface of the control switch is fitted with a lockable cover.

[0024] In the above implementation process, the control switch is locked and protected by a lockable cover to prevent unauthorized operation.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: By cooperating with the drive motor of the traction mechanism and the wire rope, the electric lifting of the high-voltage distribution cabinet can be realized, replacing the traditional high-altitude operation mode of manually climbing ladders. During maintenance, there is no need for personnel to climb high. They only need to adjust the height of the cabinet to a safe working position by controlling the switch, which greatly reduces the safety hazards such as falls from heights. At the same time, it simplifies the maintenance process. Through the double support design of the first limit block and the support plate in the locking mechanism, a stable lock can be formed when the cabinet is suspended, avoiding the risk of loosening or falling caused by long-term suspension.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figure 1-8This application provides a suspended high-voltage distribution cabinet, including a high-voltage distribution cabinet 1. A load-bearing component 2 is provided on the rear side of the high-voltage distribution cabinet 1 for guiding it. Fixing plates are welded to the top and bottom sides of the load-bearing component 2. The surfaces of the fixing plates are provided with bolt holes for fixing to the ground and wall. Through the fixing plates on the top and bottom sides, the load-bearing component 2 can be firmly anchored to the wall and ground with expansion bolts, forming a symmetrical double support structure. This evenly distributes the weight of the high-voltage distribution cabinet 1 to the wall foundation, effectively avoiding loosening caused by excessive force at a single point and improving the overall installation stability of the device. A slide rail 21 is provided on the inner side of the load-bearing component 2 for guiding the movement of the transmission roller 63. By setting the slide rail 21, high-precision guidance can be provided for the vertical movement of the transmission connecting frame 6, reducing the friction coefficient between the transmission roller 63 and the slide rail 21, ensuring that the transmission connecting frame 6 remains stable during movement, and avoiding lateral jamming or displacement.

[0031] A control switch 22 for controlling the drive motor 41, the adjustment motor 51, and the cylinder 54 is fixedly connected to the inner side wall of the support component 2. The control switch 22 integrates operation buttons for raising, lowering, locking, and unlocking. Each button is marked with a different color and function text. The control switch 22 allows for intuitive and convenient control of the device's raising and lowering actions, as well as locking the suspended state after raising. A lockable cover plate is installed on the outer surface of the control switch 22. The edge of the cover plate is connected to the support component 2 via a hinge, and the control switch 22 is locked and protected by a lock to prevent unauthorized personnel from touching or maliciously operating it, ensuring the safety of equipment operation.

[0032] A conductive connecting frame 6 is installed on the back of the high-voltage distribution cabinet 1. The conductive connecting frame 6 is slidably connected to the inside of the load-bearing component 2. An angle bracket is welded to the back of the high-voltage distribution cabinet 1. The high-voltage distribution cabinet 1 is threadedly installed to the conductive connecting frame 6 via the angle bracket. This detachable connection method facilitates the individual disassembly, assembly, maintenance, and repair of the high-voltage distribution cabinet 1. A wire rope connecting block 61 and a second limiting block 62 for abutting and limiting the first limiting block 53 are provided on the back of the conductive connecting frame 6. A conductive roller 63 is rotatably connected to the side of the conductive connecting frame 6. The conductive roller 63 uses a deep groove ball bearing as its core component, with a polyurethane rubber layer wrapped around the outer ring, which ensures the flexibility of rotation and reduces noise during movement. Through the setting of the angle bracket and the conductive roller 63, a flexible connection between the conductive connecting frame 6 and the high-voltage distribution cabinet 1 and the load-bearing component 2 is achieved, which facilitates subsequent disassembly, assembly, and maintenance work and improves the ease of operation.

[0033] The support component 2 has an internal mounting plate 3 with two sets of through holes on its surface. The first set of through holes is used for the insertion of the first limiting block 53. In the locked state, the first limiting block 53 extends into the inside of the through holes, ensuring that the limiting block can be accurately inserted and form an effective limit. In the unlocked state, the first limiting block 53 is flush with the back of the mounting plate 3, avoiding mechanical obstruction to the movement of the transmission connecting frame 6. The wire rope 44 passes through the other set of through holes to the front of the mounting plate 3. The edges of the other set of through holes are rounded to prevent the wire rope 44 from being worn by sharp edges during winding and unwinding. By setting two sets of through holes, it is not only convenient for the wire rope 44 to be smoothly inserted to the front to pull the transmission connecting frame 6, but also provides a reasonable structural space for locking and unlocking operations, effectively improving the use effect of the device.

[0034] A traction mechanism 4 is threaded onto the back of the mounting plate 3. The traction mechanism 4 is used to pull the transmission connecting frame 6 to move up and down. The traction mechanism 4 includes a steel wire rope 44 for connecting the transmission connecting frame 6 and a winding box 42 for winding the steel wire rope 44. A winding shaft 43 is rotatably connected inside the winding box 42. A drive motor 41 for driving the winding shaft 43 to rotate is installed on the side of the winding box 42. By driving the winding shaft 43 to rotate through the drive motor 41, the winding box 42 can wind or release the steel wire rope 44, thereby achieving the purpose of adjusting the up and down displacement of the transmission connecting frame 6, replacing the traditional manual lifting method and reducing labor intensity.

[0035] The back of the mounting plate 3 is also equipped with a locking mechanism 5 for locking the position of the conductive connecting frame 6. The locking mechanism 5 includes an adjusting motor 51 installed on the back of the mounting plate 3. The output end of the adjusting motor 51 is provided with an adjusting shaft 52. A first limit block 53 is welded to the surface of the adjusting shaft 52. The locking mechanism 5 also includes a cylinder 54 installed on the back of the mounting plate 3. A telescopic rod 55 is movable on one side of the cylinder 54. A support plate 56 is installed at the extension end of the telescopic rod 55.

[0036] When the first limiting block 53 is in the locked state, the bottom surface of the first limiting block 53 is flush with the top surface of the support plate 56. This structural design allows the first limiting block 53 to be supported by the support plate 56 when locked, transferring the vertical load borne by the first limiting block 53 to the cylinder 54, forming a closed-loop force transmission. This prevents the first limiting block 53 from deforming or being damaged due to the adjustment shaft 52 bearing the force alone, effectively preventing the locking state from loosening. By setting the locking mechanism 5, the transmission connecting frame 6 can be stably locked when it moves to the highest suspension position, significantly improving the stability of the suspension and structurally preventing loosening and falling during long-term suspension, thus ensuring the safety of equipment operation.

[0037] The working principle of this suspended high-voltage distribution cabinet is as follows: First, it is fixed to the wall or ground through the bolt holes of the top and bottom fixing plates of the bearing component 2. The high-voltage distribution cabinet 1 is connected to the conduction connection frame 6 by a corner bracket. When the height needs to be adjusted, the operator operates the drive motor 41 through the control switch 22, which drives the winding shaft 43 in the winding box 42 to rotate, winding and unwinding the steel wire rope 44, which drives the conduction connection frame 6 to move up and down along the slide rail 21. After reaching the suspension position, the control switch 22 triggers the locking mechanism 5, and the adjustment motor 51 drives the adjustment. The shaft 52 rotates, causing the first limiting block 53 to pass through the through hole of the mounting plate 3 and abut against the second limiting block 62. At the same time, the cylinder 54 pushes the telescopic rod 55 to extend, so that the support plate 56 is flush with the bottom surface of the first limiting block 53 to form support, thus completing the double locking. When unlocking, the control switch 22 is operated in the opposite direction, the adjusting motor 51 drives the first limiting block 53 to retract, the cylinder 54 pulls the support plate 56 to reset, and the drive motor 41 releases the wire rope 44 to lower the high-voltage distribution cabinet 1 to the maintenance height. The lockable cover plate always protects the control switch 22 to prevent misoperation.

[0038] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
