Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a switchgear busbar support device. Background Technology

[0002] A switch cabinet is an electrical device. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some switch cabinets also have high-voltage and low-voltage compartments and are equipped with high-voltage busbars. When fixing and supporting the busbars, a switch cabinet busbar support device is required.

[0003] In existing technologies, the support devices for busbar support and fixation require workers to repeatedly insert and connect the closing plates one by one. While this method can effectively support the busbar, the repeated insertion and connection of closing plates is time-consuming and labor-intensive, reducing the support efficiency of the busbar and increasing the workload of workers. Moreover, since the specifications of the closing plates are fixed, a support device of one specification can only effectively support a busbar of that specification, reducing the overall flexibility of the device. Furthermore, when adjusting the tilt angle of the busbar, existing support devices require workers to use special tools to repeatedly rotate the limit pins, which also increases the workload of workers, reduces the efficiency of busbar angle adjustment, and diminishes the overall practicality of the device.

[0004] Comparing this invention with patent application number CN220934622U, this utility model relates to the field of switchgear technology, and more particularly to a busbar support device for switchgear. Its technical solution includes a back plate and a fixing clip, with an installation ring fixedly installed on the front of the back plate. This utility model, through various structural combinations, allows the device to install and fix the busbar by snapping it in, improving the speed of busbar installation inside the device. It also provides buffering and shock absorption for the fixed busbar, reducing damage caused by external vibrations. Furthermore, the device allows for adjustment of the busbar fixing angle, facilitating adjustments and control by operators according to the busbar routing requirements. This increases the functionality of the device in supporting busbar installation and reduces limitations.

[0005] The above solution can effectively support and fix the busbar. However, when supporting the busbar, the staff still need to repeatedly insert and connect the closing plates one by one. In addition, the closing plates in the above solution are still of fixed specifications. Moreover, when adjusting the tilt angle of the busbar, the staff still need to use special tools to repeatedly rotate the limit pins, which fails to solve the problems mentioned in the background art.

[0006] Based on this, a switchgear busbar support device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-7As shown, a switchgear busbar support device includes a mounting plate 1. Adjustable plates 4 are evenly spaced on the front surface of the mounting plate 1. Rear plates 5 are located directly in front of each of the adjustable plates 4. Front plates 6 are located directly in front of each of the rear plates 5. Fixing frames 19 are fixedly connected to the right side surfaces of each of the rear plates 5. Insert plates 14 are fixedly connected to the right side surfaces of each of the front plates 6 via L-shaped plates 13. Guide grooves for the insertion plates 14 to move are formed on the front surface of each of the fixing frames 19. The device also includes:

[0036] An angle adjustment component is located inside the adjustment plate 4 and is used to adjust the tilt angle of the rear plate 5 and the front plate 6.

[0037] A fixing and restraining assembly is provided on the left side surface of the rear plate 5 and is used to close the front plate 6 and the rear plate 5.

[0038] The disassembled component is located on the right side surface of the fixed frame 19 and is used to cancel the fixing effect between the front plate 6 and the rear plate 5.

[0039] In this embodiment, when the busbar needs to be supported and fixed, simply place the busbar between the rear plate 5 and the front plate 6, and then close the rear plate 5 and the front plate 6 using the fixing and binding assembly. At this time, the front plate 6 will drive the insert plate 14 to move synchronously. When the insert plate 14 is inserted into the inside of the fixing frame 19, the fixing frame 19 and the insert plate 14 are then fixed. At this time, the busbar can be effectively fixed and supported by the cooperation between the front plate 6 and the rear plate 5, without the need for workers to repeatedly insert and connect the closing plates one by one. This effectively improves the support efficiency of the busbar and reduces the workload of the workers. When the busbar needs to be removed, simply dismantle the... By removing the components, the fixing effect between the insert plate 14 and the fixed frame 19 can be easily and effectively removed, thereby effectively separating the front plate 6 and the rear plate 5. This makes it easier for workers to remove the busbar. When it is necessary to adjust the installation angle of the busbar, the tilt angle of the front plate 6 and the rear plate 5 can be easily and effectively adjusted by using the angle adjustment component. This allows for effective adjustment of the installation angle of the busbar without the need for workers to use special tools to repeatedly rotate the limit pin. This effectively improves the efficiency of adjusting the installation angle of the busbar, reduces the workload of workers, and enhances the overall practicality and flexibility of the device.

[0040] In one embodiment, such as Figure 3 and Figure 7As shown, the angle adjustment assembly includes a rotating rod 26 rotatably connected to the middle of the inner wall of the rear side of the adjustment plate 4. The other end of the rotating rod 26 extends to the outside of the adjustment plate 4 and is fixedly connected to the middle of the rear surface of the rear plate 5. A rotating gear 27 is fixedly connected to the outside of the rotating rod 26. The upper surface of the adjustment plate 4 is symmetrically provided with guide grooves for the movement of connecting rods 29. A pull ring is fixedly connected to the top of each pair of connecting rods 29, and a locking plate 28 is fixedly connected to the bottom of each pair of connecting rods 29. A locking groove for engaging the rotating gear 27 is provided at the bottom of the locking plate 28. A return spring 30 is sleeved on the outside of the connecting rod 29. The return spring 30 abuts against the locking plate 28 and the adjustment plate 4. When it is necessary to adjust the installation angle of the busbar, simply pull the pull ring first. The connecting rod 29 moves synchronously, and the connecting rod 29 then moves the clamping plate 28 synchronously. During the movement of the clamping plate 28, the return spring 30 is squeezed. When the clamping plate 28 disengages from the outside of the rotating gear 27, the rear plate 5 is rotated. At this time, the rear plate 5 drives the rotating rod 26 to rotate synchronously, and the rotating rod 26 drives the rotating gear 27 to rotate synchronously. When the rear plate 5 rotates to the appropriate angle, the pull ring is released. At this time, the return spring 30 is reset, and the clamping plate 28 moves synchronously to reset. When the slot at the bottom of the clamping plate 28 engages with the outside of the rotating gear 27, the rotating gear 27 can be locked. At this time, the tilt angle of the rear plate 5 and the front plate 6 can be adjusted, thereby adjusting the installation angle of the busbar.

[0041] In one embodiment, such as Figure 2 and Figure 4As shown, the fixing and restraining assembly includes connecting frames 8 symmetrically arranged on the left side surface of the rear plate 5. A fixing rod 9 is fixedly connected inside the connecting frame 8, and a spiral spring 10 is fixedly connected to the outside of the fixing rod 9. A rotating sleeve 11 is fixedly connected to the other end of the spiral spring 10, and an outer plate 12 is fixedly connected to the outside of the rotating sleeve 11. The other side of each pair of outer plates 12 is fixedly connected to the left side surface of multiple front plates 6. Insulating fixing pads 7 are adhered to opposite sides of both the front plates 6 and the rear plate 5. When the busbar needs to be supported and fixed, simply move the front plate 6. The front plate 6 will then move the outer plates 12 synchronously, and the outer plates 12 will then rotate the rotating sleeves 11 synchronously. During the rotation of the rotating sleeves 11, the... When the spiral spring 10 is stretched, the front plate 6 will also drive the insert plate 14 to move synchronously. When the insert plate 14 is inserted into the inside of the fixed frame 19, the insert plate 14 and the fixed frame 19 are fixed. At this time, the front plate 6 and the rear plate 5 can be fixed. Thus, the busbar can be effectively supported and fixed through the cooperation between the front plate 6, the rear plate 5 and the insulating fixing pad 7. When the busbar needs to be removed, simply remove the fixing between the insert plate 14 and the fixed frame 19. At this time, the spiral spring 10 will reset and drive the rotating sleeve 11 to rotate synchronously. The rotating sleeve 11 will then drive the front plate 6 to move synchronously. At this time, the front plate 6 can be opened, which makes it easier for the staff to disassemble and install the busbar.

[0042] In one embodiment, such as Figures 1-3 As shown, the insulating fixing pad 7 is made of rubber. The rubber material can not only effectively protect the busbar, but also effectively improve the fixing and support effect of the busbar.

[0043] In one embodiment, such as Figure 2 and Figure 5As shown, an inner plate 15 is fixedly connected to the middle of the inner wall of the insert plate 14. A first telescopic rod 16 is fixedly connected to both the upper and lower surfaces of the inner plate 15. An arc-shaped locking block 17 is fixedly connected to the telescopic end of the first telescopic rod 16. A contact spring 18 is sleeved on the outside of the first telescopic rod 16, and the contact spring 18 abuts against the arc-shaped locking block 17 and the inner plate 15. Guide grooves for the arc-shaped locking block 17 to move are provided on the upper and lower surfaces of both the insert plate 14 and the fixing frame 19. When it is necessary to fix the front plate 6 and the rear plate 5 together, simply insert the insert plate 14 into the interior of the fixing frame 19. At this time, the insert plate 14 will move... The arc-shaped locking block 17 moves synchronously. When the arc-shaped locking block 17 enters the interior of the fixed frame 19, it will be squeezed. At this time, the arc-shaped locking block 17 will squeeze the first telescopic rod 16 and the abutment spring 18 synchronously. When the insert plate 14 drives the arc-shaped locking block 17 to move into the guide grooves on the upper and lower surfaces of the fixed frame 19, the abutment spring 18 resets and drives the arc-shaped locking block 17 to move synchronously. When the arc-shaped locking block 17 is inserted into the guide grooves on the upper and lower surfaces of the fixed frame 19, the insert plate 14 and the fixed frame 19 can be fixed. At this time, the front plate 6 and the rear plate 5 can be fixed.

[0044] In one embodiment, such as Figure 2 and Figure 6 As shown, the disassembly assembly includes a support plate 20 fixedly connected to the middle of the right side surface of the fixed frame 19. A second telescopic rod 21 is fixedly connected to both the upper and lower surfaces of the support plate 20. A pressing plate 22 is fixedly connected to the telescopic end of the second telescopic rod 21. A compression spring 23 is sleeved on the outside of the second telescopic rod 21, and the compression spring 23 abuts against the pressing plate 22 and the support plate 20. A pressing plate 24 for pressing the arc-shaped locking block 17 is fixedly connected to the opposite side of every two pressing plates 22. When it is necessary to cancel the fixing effect between the insert plate 14 and the fixed frame 19, simply press the pressing plate 22 first. During the process, the pressing plate 22 will simultaneously squeeze the second telescopic rod 21 and the compression spring 23. The pressing plate 22 will also drive the squeezing plate 24 to move synchronously. When the squeezing plate 24 squeezes the arc-shaped locking block 17 into the guide groove on the upper and lower surfaces of the fixed frame 19, the fixing between the insert plate 14 and the fixed frame 19 can be removed. At this time, the front plate 6 can be opened, which makes it easier for the staff to disassemble and assemble the busbar. After the front plate 6 is opened, the pressing plate 22 is released. At this time, the compression spring 23 returns to its original position, which will drive the pressing plate 22 and the squeezing plate 24 to move synchronously to their original positions.

[0045] In one embodiment, such as Figures 1-3As shown, each of the multiple second telescopic rods 21 is fitted with a bellows cover 25. The two ends of the bellows cover 25 are fixedly connected to the opposite side of the pressing plate 22 and the support plate 20, respectively. By setting the bellows cover 25, the second telescopic rods 21 and the compression springs 23 can be effectively protected from dust, thereby effectively extending the service life of the second telescopic rods 21 and the compression springs 23, without affecting the normal use of the second telescopic rods 21 and the compression springs 23.

[0046] In one embodiment, such as Figures 1-3 As shown, the left and right surfaces of the mounting plate 1 are fixedly connected to the connecting plate 2. The two connecting plates 2 are symmetrically provided with threaded holes for the locking bolts 3 to move. When the device needs to be fixedly installed, the connecting plate 2 can be fixedly installed to a suitable position inside the switch cabinet by using the locking bolts 3. At this time, the device can be fixedly installed, which makes it convenient for the staff to use the device.

[0047] The above embodiment discloses a busbar support device for a switchgear. When the busbar needs to be supported and fixed, simply place the busbar between the rear plate 5 and the front plate 6, then press the front plate 6. At this time, the front plate 6 will drive the insertion plate 14 to move synchronously. Then, the arc-shaped locking block 17 fixes the insertion plate 14 to the fixing frame 19, thus closing the rear plate 5 and the front plate 6. The busbar can be effectively fixed and supported through the cooperation between the front plate 6, the rear plate 5, and the insulating fixing pad 7, without the need for workers to repeatedly insert and connect the closing plates one by one. This effectively improves the support efficiency of the busbar and reduces the workload of the workers. When the busbar needs to be removed, simply press the pressing plate 22. At this time, the pressing plate 22 will drive the squeezing... The plate 24 moves synchronously. When the pressing plate 24 presses the arc-shaped card block 17 into the guide groove that is separated from the upper and lower surfaces of the fixed frame 19, the fixing effect between the insert plate 14 and the fixed frame 19 can be conveniently and effectively canceled. This effectively separates the front plate 6 and the rear plate 5, making it easier for workers to remove the busbar. When it is necessary to adjust the installation angle of the busbar, simply pull the pull ring to conveniently and effectively adjust the tilt angle of the front plate 6 and the rear plate 5. This effectively adjusts the installation angle of the busbar without the need for workers to use special tools to repeatedly rotate the limit pin. This effectively improves the adjustment efficiency of the busbar installation angle, reduces the workload of workers, and enhances the overall practicality and flexibility of the device.

[0048] 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.
