Description

Technical Field

[0001] This utility model relates to the field of busbar assembly technology, and more specifically, to a busbar assembly for a 110kV power distribution device. Background Technology

[0002] In power systems, busbars connect various current-carrying branch circuits in the distribution equipment, playing a role in collecting, distributing, and transmitting electrical energy. Busbar mounting brackets, used to fix these busbars, have thus emerged. Currently, the traditional assembly method for busbar mounting brackets in the industry involves bolts and screws, requiring bolt holes to be drilled on the inner wall of the low-voltage switchgear. This makes it difficult to adjust the installation position of the busbar mounting brackets later, necessitating re-drilling holes in the low-voltage switchgear to change the installation position. This is time-consuming, labor-intensive, and also involves damage to the low-voltage switchgear.

[0003] The common 110kV power distribution equipment uses a busbar joint frame, which can only fix the busbars, but lacks the function of quick disassembly of the busbars. In actual application, the busbars need to be fixed by slotting through the busbar clamps. As a result, the busbars have to be pulled out one by one when disassembling because they are too long. This process is not only cumbersome to operate, but also prolongs the time, ultimately causing problems that reduce maintenance and repair efficiency.

[0004] In summary, to improve the disassembly efficiency of busbars, it is necessary to solve the problem of having to pull them out one by one due to their excessive length, so that all busbars fixed on the busbar clamps can be disassembled simultaneously and quickly. Utility Model Content

[0005] The present invention provides a busbar joint structure for a 110kV power distribution device. The problem to be solved is that the busbars need to be fixed by slotting through the busbar clamps, which means that the busbars must be pulled out one by one during disassembly due to their excessive length.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a busbar joint frame for a 110kV power distribution device, comprising a transverse frame, a busbar limiting block provided on the surface of the transverse frame, a plurality of busbar limiting grooves provided at the upper end of the busbar limiting block, a rotating groove provided at the upper end of the busbar limiting block, a plurality of engaging grooves provided at the upper end of the busbar limiting block, a rotating shaft installed inside the rotating groove, a limiting engaging plate installed on the outer side of the rotating shaft, the limiting engaging plate engaging into the interior of the plurality of engaging grooves, a locking mechanism provided on the busbar limiting block, a locking plate provided on the locking mechanism, the locking plate engaging with the limiting engaging plate, and a length extension mechanism provided on the transverse frame.

[0007] In a preferred embodiment, the output end of the locking mechanism is connected to the locking plate. The locking mechanism is used to limit the position of the locking plate. The locking mechanism includes a sliding component and a reset component. The sliding component is used to limit the position of the locking plate. The output end of the reset component is connected to the locking plate. The reset component is used to control the horizontal displacement of the locking plate.

[0008] In a preferred embodiment, the sliding assembly includes a sliding groove formed inside the busbar limiting block and a plug-in groove formed on the surface of the busbar limiting block. The locking plate is slidably connected to the sliding groove, and the plug-in end of the locking plate is inserted into the interior of the plug-in groove.

[0009] In a preferred embodiment, the reset assembly includes a spring installed inside the sliding groove, a push rod installed on the upper end of the locking plate, and a strip groove formed on the upper end of the busbar limiting block. The push rod is slidably connected to the strip groove, and the end of the spring near the locking plate is connected thereto.

[0010] In a preferred embodiment, the length extension mechanism is used to extend the overall length of the frame. The length extension mechanism includes an extension component and an adsorption component. The output end of the extension component is connected to the adsorption component. The extension component is used to extend the overall length of the frame, and the adsorption component is used to adsorb onto the inner wall of the cabinet.

[0011] In a preferred embodiment, the extension assembly includes a circular groove formed inside the transverse frame, a partition plate installed inside the circular groove, lead screws symmetrically installed on both sides of the partition plate, and a sleeve installed inside the circular groove, the sleeve being threadedly connected to the lead screw.

[0012] In a preferred embodiment, the adsorption assembly includes a hexagonal nut mounted on the end of the sleeve away from the partition plate and a suction cup mounted on the side of the hexagonal nut away from the sleeve.

[0013] In a preferred embodiment, the surface of the transverse frame is provided with multiple adjustment holes, and the surface of the busbar limiting block is provided with two fixing holes.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model, by setting a flip-out limiting locking plate and a spring locking structure, allows all busbars to be released simultaneously by simply pulling the push rod, making it easy to remove longer busbars as a whole. This completely eliminates the tedious operation of pulling them out one by one. This design makes maintenance faster and easier, and significantly improves overall operational efficiency.

[0016] This invention allows for free extension and retraction of the frame length by simultaneously rotating the sleeves on both sides. Combined with suction cups, it can firmly adhere to the inner wall of power distribution cabinets of different sizes, eliminating the need for drilling and damaging the cabinet, thus improving installation adaptability.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 5 A busbar assembly frame for a 110kV power distribution device includes a transverse frame 1. A busbar limiting block 11 is provided on the surface of the transverse frame 1. Multiple busbar limiting grooves 12 are formed at the upper end of the busbar limiting block 11. A rotating groove 13 is formed at the upper end of the busbar limiting block 11. Multiple engaging grooves 14 are formed at the upper end of the busbar limiting block 11. A rotating shaft 15 is installed inside the rotating groove 13. A limiting engaging plate 16 is installed on the outer side of the rotating shaft 15. The limiting engaging plate 16 engages with the multiple engaging grooves 14. A locking mechanism is provided on the busbar limiting block 11. A locking plate 17 is provided on the locking mechanism. The locking plate 17 engages with the limiting engaging plate 16. A length extension mechanism is provided on the transverse frame 1.

[0025] It should be noted that the busbar limiting groove 12 is used to accommodate and initially position the busbar. The limiting locking plate 16 rotates around the rotating shaft 15, and its edge can be inserted into or disengaged from each locking groove 14. When the limiting locking plate 16 is inserted into the locking groove 14, its main body is located in front of the busbar limiting groove 12, thereby restricting the busbar placed in the busbar limiting groove 12 to be in the groove and preventing it from coming out forward. The locking mechanism is used to lock the limiting locking plate 16 in the state of being inserted into the locking groove 14 when it is necessary to fix the busbar, and to release the lock when it is necessary to disassemble the busbar, allowing the limiting locking plate 16 to rotate and lift.

[0026] It is worth noting that the key to this structural design is that by simply operating the locking mechanism to release the lock on the limiting plate 16, the limiting plate 16 can be rotated upwards to open, so that it is completely separated from the front space of the busbar limiting groove 12 and the locking groove 14. In this way, all the busbars covered by the limiting plate 16 can be simultaneously and horizontally removed or inserted from their respective busbar limiting grooves 12. Unlike traditional through-type structures, it is not necessary to pull the long busbars out one by one along the axial direction or insert them into multiple fixing points. This greatly simplifies the batch installation and disassembly of the busbars and significantly improves maintenance and repair efficiency.

[0027] Refer to the instruction manual appendix Figures 1 to 5 The output end of the locking mechanism is connected to the locking plate 17. The locking mechanism is used to limit the position of the limiting locking plate 16. The locking mechanism includes a sliding component and a reset component. The sliding component is used to limit the position of the locking plate 17. The output end of the reset component is connected to the locking plate 17. The reset component is used to control the horizontal displacement of the locking plate 17.

[0028] It should be noted that the horizontal movement of the locking plate 17 is the direct action by which it engages or disengages with the limiting engagement plate 16. The locking plate 17 moves under the guidance of the sliding assembly, while the reset assembly provides the power for its movement so that it automatically returns to the locked position.

[0029] Refer to the instruction manual appendix Figure 5 The sliding assembly includes a sliding groove 211 inside the busbar limiting block 11 and a plug-in groove 212 on the surface of the busbar limiting block 11. The locking plate 17 is slidably connected to the sliding groove 211, and the plug-in end of the locking plate 17 is inserted into the interior of the plug-in groove 212.

[0030] It should be noted that the sliding groove 211 provides a precise linear motion track for the locking plate 17, ensuring its smooth and directional movement. The insertion groove 212 is located at the end of the movement path of the locking plate 17. When the insertion end of the locking plate 17 is inserted into this groove, its position is precisely fixed, thereby ensuring that its engagement with the limiting locking plate 16 is firm and reliable, effectively preventing accidental unlocking due to vibration or other reasons.

[0031] Refer to the instruction manual appendix Figure 5 The reset assembly includes a spring 221 installed inside the sliding groove 211, a push rod 222 installed on the upper end of the locking plate 17, and a strip groove 223 opened on the upper end of the busbar limiting block 11. The push rod 222 is slidably connected to the strip groove 223, and the end of the spring 221 near the locking plate 17 is connected to it.

[0032] It should be noted that the spring 221 is usually in a stretched state, and its elastic force tends to push the locking plate 17 to the position where its plug end is inserted into the plug slot 212. The push rod 222 is fixed on the locking plate 17 and extends through the strip groove 223 to the outside of the busbar limiting block 11. By applying a force in the opposite direction to the elastic force to the push rod 222, the elastic force can be overcome, and the locking plate 17 can be moved along the sliding groove 211, so that its plug end is removed from the plug slot 212. After the push rod 222 is released, the elastic force of the spring 221 automatically pushes the locking plate 17 back to its original position and inserts it into the plug slot 212, restoring the locked state. The strip groove 223 provides space and guidance for the movement of the push rod 222.

[0033] Refer to the instruction manual appendix Figures 1 to 4 The length extension mechanism is used to extend the overall length of the frame. The length extension mechanism includes an extension component and an adsorption component. The output end of the extension component is connected to the adsorption component. The extension component is used to extend the overall length of the frame, and the adsorption component is used to adsorb onto the inner wall of the cabinet.

[0034] It should be noted that this mechanism enables the busbar assembly to adapt to distribution cabinets of different widths. By operating the extension component, the length of the frame extending from both ends of the main body of the horizontal frame 1 can be adjusted. The adsorption component uses negative pressure adsorption force to fix both ends of the frame to the inner wall of the cabinet, avoiding drilling holes in the cabinet for installation and achieving non-damaging and adjustable installation.

[0035] It is worth noting that the adjustable length and magnetic fixation greatly improve the flexibility and convenience of installation while protecting the integrity of the cabinet.

[0036] Refer to the instruction manual appendix Figure 3 The extension assembly includes a circular groove 311 formed inside the transverse frame 1, a partition plate 312 installed inside the circular groove 311, a lead screw 313 symmetrically installed on both sides of the partition plate 312, and a sleeve 314 installed inside the circular groove 311. The sleeve 314 is threadedly connected to the lead screw 313.

[0037] It should be noted that the circular groove 311 provides space for the installation and movement of the extension components. The partition plate 312 is fixed inside the circular groove 311, dividing the space into two parts. Two lead screws 313 are fixed on both sides of the partition plate 312 respectively. The sleeve 314 is fitted onto the two lead screws 313. When the sleeve 314 is rotated, since the lead screws 313 are fixed by the partition plate 312 and cannot move axially, the sleeve 314 itself will move along the axial direction of the lead screws 313. Because the threads of the two lead screws 313 are set in the same direction, rotating the sleeve 314 will cause them to move simultaneously to both ends or simultaneously to the center, thereby driving the adsorption components connected to both ends to extend and retract synchronously, realizing the adjustment of the overall length of the frame.

[0038] Refer to the instruction manual appendix Figure 4 The adsorption assembly includes a hexagonal nut 321 installed on the end of the sleeve 314 away from the partition plate 312 and a suction cup 322 installed on the side of the hexagonal nut 321 away from the sleeve 314.

[0039] It should be noted that one end of the hexagonal nut 321 is connected to the sleeve 314, and the other end is used to install the suction cup 322. The suction cup 322 can fit tightly against the inner wall of the cabinet. By pressing the suction cup 322, the air inside is expelled, forming a negative pressure, which generates an adsorption force to fix the frame to the cabinet. The design of the hexagonal nut 321 makes it easy to use tools to tighten it to adjust the extension length of the sleeve 314.

[0040] Refer to the instruction manual appendix Figures 4 to 5 The surface of the transverse frame 1 has multiple adjustment holes 18, and the surface of the busbar limiting block 11 has two fixing holes 19.

[0041] It should be noted that multiple adjustment holes 18 are arranged along the length of the transverse frame 1. The fixing holes 19 of the busbar limiting block 11 are used to insert fasteners such as bolts and screws. When installing the busbar limiting block 11, it is placed in a suitable position on the transverse frame 1 according to the arrangement requirements of the busbar, so that the fixing holes 19 are aligned with the corresponding adjustment holes 18, and then fixed with fasteners. In this way, the position of the busbar limiting block 11 can be flexibly adjusted within the length range of the transverse frame 1.

[0042] Working principle: When installing busbars, first place each busbar into the corresponding busbar limiting groove 12 on the busbar limiting block 11. Then, rotate the limiting engagement plate 16 downwards, causing it to rotate around the rotating shaft 15 until the edge of the limiting engagement plate 16 engages with the interior of the multiple engagement grooves 14. At this time, the limiting engagement plate 16 covers the front of the busbar limiting groove 12, preventing the busbars from coming out. Then, release the push rod 222. Under the action of the spring 221, the locking plate 17 slides horizontally along the sliding groove 211, inserts into the insertion groove 212, and engages with the limiting engagement plate 16 to achieve a firm lock. When disassembling, pull the push rod 222. The push rod 222 slides along the strip groove 223 and drives the locking plate 17 to overcome the spring 221 and exit the insertion groove 212, releasing the lock. When the limiting locking plate 16 is locked, it can be rotated upward to open and disengage from the locking groove 14 and the busbar limiting groove 12 area. All busbars can then be removed horizontally forward simultaneously without needing to be pulled out axially one by one. When the width of the distribution cabinet changes, the inner wall of the sleeve 314 engages with the screw 313 symmetrically installed on both sides of the partition plate 312 by rotating the sleeve 314. The rotation of the sleeve 314 drives it to move along the axis of the screw 313, which in turn moves the adsorption component connected to its end, thereby expanding or contracting the overall length of the frame. After adjusting to the required length, the suction cup 322 at the end of the adsorption component is pressed against the inner wall of the distribution cabinet, and air is discharged to form a negative pressure adsorption fixation. The hexagonal nut 321 facilitates tool operation of the sleeve 314.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
