Description

Technical Field

[0001] This application relates to the field of high voltage switchgear technology, and in particular to a compact high voltage switchgear quick assembly structure. Background Technology

[0002] High-voltage switchgear, also known as high-voltage switch cabinets, is a core piece of equipment in a power system used for receiving and distributing electrical energy, and for controlling, protecting, and monitoring high-voltage circuits. It reliably connects or disconnects high-voltage electrical equipment such as lines, transformers, and motors according to the needs of the power grid operation, and can quickly clear faults to prevent large-scale power outages, thus playing a vital role. Currently, the design of high-voltage switchgear tends towards modularity and compactness to improve space utilization and installation efficiency.

[0003] A compact high-voltage switchgear exists in the prior art, comprising an upper cabinet and a lower cabinet. The top of the lower cabinet is fitted onto the bottom of the upper cabinet and slidably connected to it in a vertical direction. Both the top side wall of the lower cabinet and the side wall of the upper cabinet have several holes. Several fixing bolts are also provided on the lower cabinet, each passing through one of the holes in both the lower and upper cabinets to secure and assemble them. In use, the upper and lower cabinets are slid together to adjust their overall height, and then each fixing bolt is installed to complete the assembly of the upper and lower cabinets.

[0004] Regarding the aforementioned technologies, the existing technology requires several fixing bolts to secure the upper and lower cabinets. This necessitates maintaining the installation height of the upper cabinet during assembly, allowing the upper cabinet to be secured only after some fixing bolts are installed. Furthermore, each fixing bolt must be installed, thus reducing the assembly efficiency between the upper and lower cabinets. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the assembly efficiency between the upper and lower cabinets, this application provides a compact rapid assembly structure for high-voltage switchgear.

[0006] This application provides a compact high-voltage switchgear quick assembly structure, which adopts the following technical solution: A compact high-voltage switchgear quick assembly structure includes a fixing mechanism, which comprises a fixing frame and a insertion frame. The fixing frame is mounted on and connected to an upper cabinet, and a plurality of fixing slots are provided on the side wall of the fixing frame. The insertion frame is mounted on a lower cabinet and slidably connected to the lower cabinet, with the sliding direction being different from the sliding direction between the upper and lower cabinets. The insertion frame is used to fix the upper and lower cabinets by being inserted into the fixing slots.

[0007] By adopting the above technical solution, compared with the prior art, where workers need to maintain the installation height of the upper cabinet, and can only release the upper cabinet after some fixing bolts are installed, and each fixing bolt needs to be installed to achieve the assembly between the upper and lower cabinets, thus reducing the assembly efficiency between the upper and lower cabinets, this application, through the setting of the fixing mechanism, allows the insertion bracket to be inserted into the fixing slot at the corresponding height on the fixing frame during the sliding process of the upper and lower cabinets, so as to initially fix the upper and lower cabinets together. This eliminates the need for workers to manually maintain the height of the upper cabinet and reduces the number of fixing bolts required, effectively facilitating the assembly between the upper and lower cabinets, thereby increasing the assembly efficiency of the high-voltage switchgear and realizing the rapid assembly of the high-voltage switchgear.

[0008] Preferably, the lower cabinet is also provided with a support frame, and the inner sidewalls of both the lower cabinet and the upper cabinet are provided with sliding grooves. The two ends of the support frame are respectively inserted into the sliding grooves on the lower cabinet and the upper cabinet, and are slidably connected to the inner wall of the sliding groove.

[0009] By adopting the above technical solution and setting up the support frame, after the upper and lower cabinets are initially fixed by the fixing frame and the insertion frame, the staff can insert the two ends of the support frame into the sliding grooves on the lower and upper cabinets respectively, thereby reinforcing the side walls of the upper and lower cabinets and ensuring the stability of the connection between the upper and lower cabinets.

[0010] Preferably, the fixing mechanism further includes a reset member and a fixing component. The reset member is used to allow the insertion bracket to be inserted into the corresponding fixing groove by its own elasticity. One end of the insertion bracket inserted into the fixing groove is set to be hemispherical so as to abut against the inner wall of the corresponding fixing groove. The fixing component is used to drive the insertion bracket to slide so that the insertion bracket is inserted deep into the corresponding fixing groove.

[0011] By adopting the above technical solution, the reset component and the fixing component are designed so that the reset component can use its own elasticity to allow the hemispherical end of the insertion frame to be inserted into the fixing groove at the corresponding height, thereby achieving initial locking between the upper and lower cabinets. At the same time, the presence of the fixing component can drive the fixing frame to slide after the upper and lower cabinets are initially locked, so that the fixing frame is inserted deep into the fixing groove. This causes the inner wall of the fixing groove to no longer abut against the hemispherical end wall, but against the top wall of the fixing frame, thereby achieving further locking between the upper and lower cabinets and reducing the probability of accidental slippage between the upper and lower cabinets.

[0012] Preferably, the fixing component includes a sliding frame and a transmission frame. The sliding frame is slidably connected to the lower cabinet and the sliding direction is the same as the sliding direction of the support frame. The sliding frame is located on the sliding path of the support frame. One end of the transmission frame is rotatably connected to the sliding frame and the other end is rotatably connected to the insertion frame.

[0013] By adopting the above technical solution and setting the fixing component, the support frame can abut against the sliding frame during the sliding process in the corresponding sliding groove, thereby pushing the sliding frame to slide. The sliding frame then drives the fixing frame to slide through the transmission frame, so that the end of the fixing frame continues to be inserted into the corresponding fixing groove, thereby realizing the driving of the fixing frame to slide. At the same time, the operator can drive the fixing frame during the insertion of the support frame, which effectively facilitates the operator's operation and increases the assembly efficiency.

[0014] Preferably, the lower cabinet is also provided with a locking mechanism, which includes a locking frame and an elastic element. The locking frame is slidably connected to the lower cabinet and its sliding direction is different from that of the support frame. The elastic element is used to allow the locking frame to be continuously inserted into the corresponding support frame through its own elastic force.

[0015] By adopting the above technical solution and setting the locking mechanism, the locking frame can be continuously inserted into the support frame under the elastic force of the elastic element, thereby locking the support frame, effectively reducing the probability of the support frame shifting unexpectedly, ensuring the support effect of the support frame, and thus achieving reinforcement between the upper cabinet and the lower cabinet.

[0016] Preferably, the locking mechanism further includes a limiting component, which includes a limiting frame and a linkage. One end of the limiting frame is rotatably connected to the lower cabinet, and the other end is located on the side of the locking frame near the support frame and abuts against the locking frame to prevent the locking frame from being inserted into the support frame. The support frame drives the limiting frame to rotate through the linkage.

[0017] By adopting the above technical solution and setting the limiting component, the limiting frame can abut against the side of the locking frame near the support frame, thereby limiting the locking frame. During the insertion of the support frame, the limiting frame can be rotated by the linkage component. After the support frame is inserted at the end, the limiting frame can release the limiting of the locking frame, allowing the locking frame to be automatically inserted into the support frame under the elastic force of the elastic component, thus achieving automatic locking of the support frame without the need for manual locking by the staff, effectively ensuring the smooth locking of the support frame.

[0018] Preferably, the locking mechanism further includes a retaining assembly, which includes a retaining frame and a retaining member. The retaining frame is located on the side of the locking frame away from the support frame and on the sliding path of the locking frame. The retaining member is used to allow the retaining frame to be inserted into the locking frame by its own elasticity.

[0019] By adopting the above technical solution and setting the retaining component, when the support frame needs to be unlocked, the staff can manually push the locking frame away from the support frame. After the locking frame is completely detached from the support frame, the retaining frame can be inserted into the locking frame under the elastic force of the retaining component, locking the locking frame in this state. This keeps the locking frame detached from the support frame, facilitating the disassembly of the support frame and effectively simplifying the disassembly of the support frame for the staff.

[0020] Preferably, the locking mechanism further includes an unlocking component, which includes an unlocking frame, a driving frame, and a driving member. The unlocking frame is slidably connected to the lower cabinet body. One end of the driving frame is rotatably connected to the unlocking frame, and the other end is rotatably connected to the retaining frame. The retaining frame drives the unlocking frame to slide through the driving member.

[0021] By adopting the above technical solution and configuring the unlocking component, as the support frame slides outward, causing the sliding frame to drive the limiting frame to rotate back, the limiting frame can drive the unlocking frame to slide through the driving component. This allows the unlocking frame to drive the fixing frame to gradually disengage from the locking frame through the driving frame, thereby unlocking the locking frame. After unlocking, the locking frame can smoothly slide towards the support frame, effectively achieving automatic reset of the support frame and facilitating operation by staff.

[0022] Preferably, the driving component includes a driving rod, one end of which is connected to the limiting frame, and the other end is located on the side of the limiting frame away from the sliding frame. The unlocking frame is located on the displacement path of the end of the driving rod away from the limiting frame.

[0023] By adopting the above technical solution and setting the driving rod, the limiting frame can drive the driving rod to rotate together during the rotation of the limiting frame back, so that the driving rod gradually abuts against the unlocking frame, thereby pushing the unlocking frame to slide and driving the unlocking frame. This effectively realizes the automatic reset of the support frame and also facilitates the operation of the staff.

[0024] Preferably, the linkage component includes a linkage frame, one end of which is rotatably connected to the sliding frame, and the other end is rotatably connected to the limiting frame, and the rotatable connection point is different from the rotatable connection point of the limiting frame itself.

[0025] By adopting the above technical solution and setting the linkage frame, the sliding frame can drive the limiting frame to rotate through the linkage frame, thereby realizing the linkage between the sliding frame and the limiting frame, and further realizing the linkage between the support frame and the limiting frame. This effectively facilitates the operation of the staff and improves the assembly efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The setting of the fixing mechanism allows the insertion bracket to be inserted into the fixing slot at the corresponding height on the fixing frame during the sliding process of the upper and lower cabinets, so as to initially fix the upper and lower cabinets together. This eliminates the need for workers to manually maintain the height of the upper cabinet and reduces the number of fixing bolts required. It effectively facilitates the assembly of the upper and lower cabinets by workers, thereby increasing the assembly efficiency of the high-voltage switchgear and realizing the rapid assembly of the high-voltage switchgear. The reset component and fixing component are designed so that the reset component can use its own elasticity to allow the hemispherical end of the insertion frame to be inserted into the fixing groove at the corresponding height, thereby achieving initial locking between the upper and lower cabinets. At the same time, the presence of the fixing component can drive the fixing frame to slide after the upper and lower cabinets are initially locked, so that the fixing frame is inserted deep into the fixing groove. This causes the inner wall of the fixing groove to no longer abut against the hemispherical end wall, but against the top wall of the fixing frame, thereby achieving further locking between the upper and lower cabinets and reducing the probability of accidental slippage between the upper and lower cabinets. The limiting component allows the limiting frame to abut against the side of the locking frame closest to the support frame, thus limiting the locking frame. During the insertion of the support frame, the limiting frame can be rotated via the linkage, allowing it to release its restriction on the locking frame after the support frame is inserted at the end. This enables the locking frame to automatically insert into the support frame under the elastic force of the elastic element, achieving automatic locking of the support frame without the need for manual locking by personnel, effectively ensuring smooth locking of the support frame.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a compact, rapid assembly structure for high-voltage switchgear. (Refer to...) Figure 1 The compact high-voltage switchgear quick assembly structure includes a fixing mechanism 1, which comprises a fixing frame 11 and a insertion frame 12. The fixing frame 11 is mounted on and connected to the upper cabinet. Several fixing slots 111 are also provided on the side wall of the fixing frame 11. The insertion frame 12 is mounted on the lower cabinet and slidably connected to it, with its sliding direction different from the sliding direction between the upper and lower cabinets. The insertion frame 12 is used to fix the upper and lower cabinets together by being inserted into the fixing slots 111.

[0034] Reference Figure 1 and Figure 2 The lower cabinet has an opening at its top, allowing the bottom of the upper cabinet to be inserted into it and abut against the inner wall of the opening, thus enabling sliding between the upper and lower cabinets. The fixing frame 11 is fixedly connected to the inner wall of the upper cabinet by welding or bolts. In this embodiment, each fixing groove 111 is formed on the side wall of the fixing frame 11 along the length of the lower cabinet, and all grooves are through-holes, with several fixing grooves 111 evenly distributed vertically.

[0035] Reference Figure 1 and Figure 3 In this embodiment, two insertion brackets 12 are provided, located on opposite sides of the fixed frame 11. Each insertion bracket 12 is slidably connected to the inner wall of the lower cabinet via a sliding groove 3, and the sliding direction is set to the length direction of the lower cabinet. The ends of the two insertion brackets 12 that are close to each other are both hemispherical, so that when the fixed frame 11 moves downward, it can abut against the inner wall of the sliding groove 3, thereby pushing the insertion bracket 12 to slide and make room, which facilitates the control of the height of the upper cabinet.

[0036] Reference Figure 1 and Figure 3 The fixing mechanism 1 also includes a reset member 13 and a fixing component 14. In this embodiment, there are two reset members 13 and two fixing components 14, each corresponding to a insertion bracket 12. In this embodiment, each reset member 13 is a pressure spring, and each pressure spring is sleeved on the corresponding insertion bracket 12. One end of each spring abuts against the side of the corresponding insertion bracket 12 away from the fixing bracket 11, and the other end abuts against the inner wall of the lower cabinet, so that the hemispherical end of the insertion bracket 12 abuts against the inner wall of the slide groove 3 through its own elasticity.

[0037] Reference Figure 1 and Figure 2 The lower cabinet has support frames 2 on both inner walls along its length. Both the lower and upper cabinets have sliding grooves 3 on their inner walls along their length, extending along the width of the lower cabinet to reach the depth of the opening in either cabinet. The upper cabinet has several sliding grooves 3 on its inner wall, distributed along its height.

[0038] Reference Figure 2 One end of the support frame 2 is inserted into the corresponding slide groove 3 of the upper cabinet located above the lower cabinet, and the other end is inserted into the corresponding slide groove 3 of the lower cabinet. Both ends are slidably connected to the inner wall of the corresponding slide groove 3, and the sliding direction is the width direction of the lower cabinet, thereby reinforcing the upper and lower cabinets. In this embodiment, both ends of the support frame 2 are designed as dovetails. The bottom wall of the top of the support frame 2 abuts against the top of the lower cabinet, thereby supporting the upper cabinet through abutment and ensuring the stability of the upper cabinet.

[0039] Reference Figure 1 and Figure 3Each fixed component 14 includes a sliding frame 141 and a transmission frame 142. Each sliding frame 141 is slidably connected to the lower cabinet via a slide rail, and the sliding direction is the same as the sliding direction of the corresponding support frame 2. Each sliding frame 141 is located on the side of the corresponding support frame 2 closest to the fixed frame 11, and is located on the sliding path of the corresponding support frame 2. One end of each transmission frame 142 is rotatably connected to the corresponding sliding frame 141 via a pin, and the other end is rotatably connected to the corresponding insertion frame 12 via a pin, so that after the support frame 2 abuts against the sliding frame 141, it can push the sliding frame 141 to slide, thereby causing the sliding frame 141 to drive the insertion frame 12 to move and approach another insertion frame 12 through the transmission frame 142, so that the hemispherical end on the insertion frame 12 completely moves into the corresponding fixed groove 111, changing the abutment position between the insertion frame 12 and the inner wall of the fixed frame 11.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The lower cabinet is also equipped with two locking mechanisms 4, each corresponding to one of the two support frames 2. Each locking mechanism 4 includes a locking frame 41, an elastic element 42, and a limiting component 43. The locking frame 41 is slidably connected to the lower cabinet via a slide groove 3, and the sliding direction is the height direction of the lower cabinet. Several locking rods extend upward from the top of the locking frame 41 to be inserted into the bottom of the support frame 2.

[0041] Reference Figure 1 and Figure 4 In this embodiment, the elastic element 42 is configured as a pressure spring. Each pressure spring is sleeved on the bottom of the locking frame 41, and the top end of each spring abuts against the corresponding locking frame 41, and the bottom end abuts against the lower cabinet. The locking frame 41 is continuously inserted into the corresponding support frame 2 by its own elasticity, so as to lock the support frame 2.

[0042] Reference Figure 3 and Figure 4 Each limiting component 43 includes a limiting frame 431 and a linkage 432. The top of each limiting frame 431 is rotatably connected to the lower cabinet via a pin, and the bottom extends downward. When the locking frame 41 is not inserted into the support frame 2, its end is located on the side of the corresponding locking frame 41 close to the support frame 2 and is located on the sliding path of the corresponding support frame 2. When the locking frame 41 is inserted into the support frame 2, the bottom of the limiting frame 431 is located on the side of the locking frame 41 close to the fixed frame 11.

[0043] Reference Figure 3 and Figure 4Each linkage component 432 includes a linkage frame 4321. One end of each linkage frame 4321 is rotatably connected to the corresponding sliding frame 141 via a pin, and the other end is rotatably connected to the corresponding limiting frame 431 via a pin. The rotatable connection point is different from the rotatable connection point of the limiting frame 431 itself.

[0044] Reference Figure 1 , Figure 3 and Figure 4 In the initial state, when the support frame 2 is not inserted into the slide groove 3, the sliding frame 141 is located on the side of its sliding path away from the fixed frame 11. At this time, the bottom end of the limiting frame 431 is above the locking frame 41 and abuts against the locking frame 41, thus preventing the locking frame 41 from continuing to slide. When the support frame 2 is inserted into the slide groove 3 and slides, the support frame 2 gradually approaches the sliding frame 141. When the support frame 2 abuts against the sliding frame 141, thereby pushing the sliding frame 141 to slide, the sliding frame 141, through the transmission frame 142, drives the insertion frame 12 to be further inserted into the fixed groove 111.

[0045] During this process, the sliding frame 141 drives the limiting frame 431 to rotate via the linkage frame 4321, causing the bottom of the limiting frame 431 to gradually rotate downwards and approach the end of the locking frame 41. When the support frame 2 slides to the end of its sliding path, the sliding frame 141 is located at the end of its sliding path closest to the fixed frame 11. At this time, the bottom of the limiting frame 431 just disengages from the locking frame 41, thus engaging the limiting action on the locking frame 41. This allows the locking frame 41 to be inserted into the support frame 2 under the elastic force of the elastic member 42, locking the support frame 2.

[0046] Reference Figure 1 , Figure 3 and Figure 4 Each locking mechanism 4 further includes a retaining component 44 and an unlocking component 45. Each retaining component 44 includes a retaining frame 441 and a retaining element 442. Each retaining frame 441 is located on the side of the corresponding locking frame 41 away from the support frame 2, that is, below the corresponding locking frame 41. Each retaining frame 441 is slidably connected to the lower cabinet, and the sliding direction is perpendicular to the sliding direction of the locking frame 41.

[0047] Reference Figure 3 and Figure 4 Each retaining bracket 441 has an arc-shaped guide surface at its top end, so that when the retaining bracket 11 slides downward, it can abut against the guide surface of the retaining bracket 441, pushing the retaining bracket 441 to slide and make way for the locking bracket 41. Each locking bracket 41 has an opening on its side wall, so that when it slides downward, the retaining bracket 441 can be inserted to lock the locking bracket 41.

[0048] Reference Figure 4 In this embodiment, the retaining member 442 is configured as a pressure spring, which is sleeved on the corresponding retaining frame 441, with one end abutting against the corresponding retaining frame 441 and the other end abutting against the lower cabinet, so that the retaining frame 441 can be continuously inserted into the locking frame 41 through its own elastic force.

[0049] Reference Figure 3 and Figure 4 Each unlocking component 45 includes an unlocking frame 451, a driving frame 452, and a driving element 453. Each unlocking frame 451 is slidably connected to the lower cabinet via a sliding groove 3, and its sliding direction is parallel to the sliding direction of the corresponding sliding frame 141. Each driving element 453 includes a driving rod 4531, the top of which is fixedly connected to the corresponding limiting frame 431, and the bottom of which extends downward and is located on the side of the corresponding unlocking frame 451 near the fixed frame 11. One end of each driving frame 452 is rotatably connected to the corresponding unlocking frame 451 via a pin, and the other end is rotatably connected to the corresponding fixing frame 441 via a pin.

[0050] Reference Figure 1 , Figure 3 and Figure 4 In the initial state, when the locking frame 41 is above the retaining frame 441, the unlocking frame 451 is located on the side of its sliding path away from the locking frame 41. When the operator slides the locking frame 41 downwards, so that the retaining frame 441 is inserted into the locking frame 41, when the sliding frame 141 slides away from the retaining frame 11, the sliding frame 141 drives the limiting frame 431 to rotate through the linkage frame 4321, so that the limiting frame 431 drives the driving rod 4531 to rotate together and gradually approach the unlocking frame 451.

[0051] When the driving rod 4531 abuts against the unlocking frame 451, the driving rod 4531 pushes the unlocking frame 451 to slide, thereby causing the unlocking frame 451 to drive the retaining frame 441 to slide and gradually disengage from the locking frame 41 through the driving frame 452. When the retaining frame 441 is completely disengaged from the locking frame 41, the locking frame 41 moves upward under the elastic force of the elastic member 42 and abuts against the bottom of the limiting frame 431.

[0052] Reference Figure 1 In this embodiment of the application, the upper cabinet is also provided with an upper cabinet door, and the lower cabinet is also provided with a lower cabinet door. The upper cabinet door is rotatably connected to the upper cabinet via a pin, and the lower cabinet door is rotatably connected to the lower cabinet via a pin. The bottom of the upper cabinet is inserted into the top opening of the lower cabinet door and is slidably connected to the lower cabinet door. The sliding direction is vertical to accommodate the sliding between the upper and lower cabinets.

[0053] The implementation principle of the compact high-voltage switchgear quick assembly structure in this application embodiment is as follows: When it is necessary to assemble the upper cabinet and the lower cabinet, the bottom of the upper cabinet is inserted into the top opening of the lower cabinet, and the upper cabinet door is inserted into the top opening of the lower cabinet door. After the upper cabinet slides to the specified height, the fixing bracket 11 is initially inserted into the corresponding fixing groove 111 under the elastic force of the reset member 13. Subsequently, the end of the support bracket 2 is inserted into the corresponding sliding groove 3 on the upper and lower cabinets, and the support bracket 2 is slid.

[0054] When the support frame 2 abuts against the sliding frame 141, thereby pushing the sliding frame 141 to slide, the sliding frame 141, through the transmission frame 142, drives the insertion frame 12 to be further inserted into the fixing groove 111. During this process, the sliding frame 141 drives the limiting frame 431 to rotate through the linkage frame 4321, thereby causing the bottom of the limiting frame 431 to gradually rotate downward and gradually approach the end of the locking frame 41.

[0055] When the support frame 2 slides to the end of its sliding path, the sliding frame 141 is located at the end of its sliding path closest to the fixed frame 11. At this time, the bottom of the limiting frame 431 just disengages from the locking frame 41, thereby contacting the limiting of the locking frame 41, so that the locking frame 41 can be inserted into the support frame 2 under the elastic force of the elastic member 42, locking the support frame 2 and realizing the assembly between the upper cabinet and the lower cabinet.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
