Description

Technical Field

[0001] The present invention relates to the technical field of busbar fixing, and particularly relates to a busbar fixing structure and a power distribution cabinet. Background Art

[0002] A busbar is one of the main devices for distributing electric power in a power system. It is usually used to transmit electric energy from a power source to different loads or electrical equipment. It is a conductive metal bar, tube or bar-shaped structure with strong conductivity and small impedance. It is commonly found in distribution boards, distribution rooms, electrical substations, etc. and is usually composed of 1-5 metal plates arranged in a row.

[0003] In the authorized patent with the authorized announcement number CN220692555U, there is disclosed a prefabricated switchgear busbar device, which includes multiple groups of busbar assemblies, a cabinet body and at least two busbar limiting devices. Among them, multiple groups of the busbar assemblies are arranged horizontally and parallel to each other. Each group of the busbar assemblies includes at least two busbars and at least one copper bar. Among them, every two busbars in the same group are connected to a copper bar by bolts; each of the busbar limiting devices is preset with multiple groups of mounting holes. Among them, the busbars of multiple different busbar assemblies are respectively installed in one busbar limiting device, and the different busbars of the same group of busbar assemblies are installed in different busbar limiting devices; each of the busbars includes at least two horizontally aligned and parallel busbar members; each of the busbar limiting devices is preset with multiple mounting holes for the busbar members to pass through and be installed; each of the busbar limiting devices is fixedly connected to the top of the cabinet body: by respectively passing the busbar members of two busbars in the same group through the mounting holes of two busbar limiting devices, and then fixedly connecting the busbar limiting devices to the cabinet body, the quick installation of the busbar and the busbar limiting device is realized, and the quick connection of multiple groups of busbar assemblies is completed. Among them, the use of bolt connectors is reduced, and the installation efficiency is improved.

[0004] However, there are still the following problems in this solution. In order to ensure that different groups of busbars can be inserted and fixed during installation, the distance between each busbar in the same group is usually the same as the thickness of the busbar. However, in the above solution, the size and distance of the mounting holes of the busbar limiting device are fixed, which results in that this solution can only be applicable to the fixing of busbars with a fixed thickness size and cannot be applicable to the fixing between busbars of different models.

Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] As Figures 1 to 12 shown, the busbar fixing structure of the present invention includes a bracket 1, a mounting seat 20, a partition assembly 30, an adjusting member 40, a pushing assembly 50, and a lifting assembly 60.

[0037] Referring to Figures 4 - 6 , the bracket 1 is composed of two symmetrically arranged cross plates 10 up and down. The bottom of the cross plate 10 is provided with a placement groove 11. An empty groove 12 and a top groove 13 are provided inside the cross plate 10 along its length direction, and the empty groove 12 communicates with the placement groove 11, and the top groove 13 is located above the empty groove 12.

[0038] Referring to Figures 4 - 5 , a plurality of mounting seats 20 are all arranged in the empty groove 12 and are located on one side of the placement groove 11. A through groove 21 is provided in the middle of each mounting seat 20. An elastic member 22 is provided between adjacent mounting seats 20 for elastic support between adjacent mounting seats 20. In this solution, the elastic member 22 is specifically a spring. A limiting groove 23 is provided inside the mounting seat 20 along its height direction to facilitate the installation of the adjusting member 40. The top of the mounting seat 20 is fixedly installed with a sliding seat 24, and the sliding seat 24 is slidably assembled inside the top groove 13 to facilitate the movement of the mounting seat 20 in the empty groove 12.

[0039] Referring to Figure 5 , Figure 7 ,Figure 8 and Figure 9 , the separating component 30 includes a suspension plate 31 and a partition plate 32. The suspension plate 31 is fixedly installed at the bottom of the mounting seat 20 and extends into the placement groove 11. The partition plate 32 is inclined and rotatably assembled at the bottom end of the suspension plate 31, and can support and separate adjacent busbars at both ends of the partition plate 32. By rotating the partition plate 32 on the suspension plate 31 to adjust the inclination angle of the partition plate 32, the horizontal distance between the upper and lower ends of the partition plate 32 can be changed, that is, the separation distance between adjacent two busbars can be adjusted, so as to adapt to the support of busbars with different thicknesses. A chute 321 is opened inside the partition plate 32, and a side groove 322 is opened on the side wall of the chute 321.

[0040] Reference Figure 7 , the adjusting member 40 includes a cross bar 41 and a push rod 42. The cross bar 41 is slidably assembled inside the limit groove 23, the push rod 42 is slidably arranged on the cross bar 41, and the bottom end of the push rod 42 is slidably arranged in the chute 321. By sliding the cross bar 41 up and down inside the limit groove 23 to drive the push rod 42 to lift and lower, the bottom end of the push rod 42 moves in the chute 321, and then drives the partition plate 32 to rotate on the suspension plate 31 to adjust the inclination angle of the partition plate 32 and change the separation distance between the two busbars.

[0041] Reference Figure 6 , Figure 7 and Figure 11 , a cross groove 411 is opened inside the cross bar 41, a convex block 421 is fixedly connected to the top end of the push rod 42, and the convex block 421 is slidably assembled in the cross groove 411, so that the cross bar 41 can support the push rod 42 through the convex block 421, and the push rod 42 can slide in the cross bar 41 through the convex block 421, which is convenient for the mounting seat 20 to drive the push rod 42 to move synchronously during movement. A side shaft 422 is rotatably assembled at the bottom end of the push rod 42, and one end of the side shaft 422 away from the push rod 42 extends into the side groove 322. By the movement of the side shaft 422 in the side groove 322, the push rod 42 can drive the partition plate 32 to rotate during lifting and lowering. A base 412 is fixedly installed at the bottom of the cross bar 41, an adjusting bolt 413 is threadedly connected inside the base 412, and the adjusting bolt 413 is rotatably assembled in the cross plate 10. By rotating the adjusting bolt 413 to push the base 412 to lift and lower, the cross bar 41 can be driven to lift and lower.

[0042] Reference Figure 6 and Figure 7, the pushing component 50 includes a push plate 51 and a limit block 52. There are two push plates 51 symmetrically distributed at both ends of the placement groove 11, and the two push plates 51 are respectively in close contact with the mounting seats 20 at both ends of the placement groove 11. The limit block 52 is fixedly installed on the top of the push plate 51, and the top end of the limit block 52 is slidably assembled inside the top groove 13. By sliding the limit block 52 along the top groove 13, the push plate 51 is moved within the empty groove 12, causing the two push plates 51 to approach each other and then push the two mounting seats 20 at the ends, making the mounting seats 20 at both ends of the placement groove 11 move towards the middle, so that several mounting seats 20 in the middle are pushed and moved by the elastic member 22, and multiple partition plates 32 push the busbars towards the middle to complete the clamping and positioning of the busbars. A first lead screw 53 rotatably assembled on the cross plate 10 is arranged in the empty groove 12. Two sets of threads with opposite helix directions are provided on the first lead screw 53, and the two push plates 51 are respectively threadedly connected to the two sets of threads of the first lead screw 53. A knob is arranged at the end of the first lead screw 53. The first lead screw 53 passes through the through groove 21 on the mounting seat 20, and the diameter of the through groove 21 is larger than the diameter of the first lead screw 53, so that there is no contact between the first lead screw 53 and the mounting seat 20. When the first lead screw 53 is rotated, the two push plates 51 can be pushed to move synchronously in opposite directions, approaching each other or moving away from each other, and then the distance between adjacent mounting seats 20 can be adjusted to increase or decrease synchronously.

[0043] Reference Figure 6 , the lifting component 60 includes a rotating seat 61, a second lead screw 62 and a threaded barrel 63. The rotating seat 61 is rotatably assembled on one of the cross plates 10. The second lead screw 62 is fixedly installed on the rotating seat 61. The threaded barrel 63 is fixedly installed on the other cross plate 10 and is threadedly connected to the outside of the second lead screw 62. By driving the second lead screw 62 to rotate through the rotating seat 61, the second lead screw 62 can push the threaded barrel 63 to move, and the distance between the two cross plates 10 can be adjusted to facilitate adapting to busbars of different widths.

[0044] Reference Figures 1 - 3 , the power distribution cabinet of the present invention includes a cabinet body 2 and a mounting frame 70. The mounting frame 70 is fixedly installed inside the cabinet body 2. A sliding table 71 is slidably assembled in the mounting frame 70, and the cross plate 10 is fixedly installed on the sliding table 71. The sliding table 71 can support the cross plate 10 and adjust the height of the cross plate 10 as the sliding table 71 slides. A vertical groove 72 is formed in the side wall of the mounting frame 70. A lead screw 73 is fixedly installed on the side wall of the sliding table 71, and the lead screw 73 passes through the vertical groove 72. A locking nut 74 is threadedly connected to the outside of the lead screw 73, and the locking nut 74 abuts against the side wall of the mounting frame 70, thereby locking the position of the sliding table 71 and keeping the bracket 1 at a fixed height.

[0045] Working principle: The slide table 71 slides within the mounting frame 70 to adjust the bracket 1 to an appropriate height. Then, the screw rod 73 cooperates with the locking nut 74 to lock and fix the position of the bracket 1. Place the end of the busbar between two adjacent partitions 32. Drive the second lead screw 62 to rotate by the rotating seat 61, so that the second lead screw 62 pushes the threaded cylinder 63 to move, making the two cross plates 10 close to the upper and lower sides of the busbar. Rotate the adjusting bolt 413 to push the base 412 to descend, so that the cross bar 41 descends within the empty slot 12. The push rod 42 pushes the partition 32 to rotate on the hanging plate 31, adjusts the inclination angle of the partition 32, changes the horizontal distance between the upper and lower ends of the partition 32, adjusts the separation distance between two adjacent busbars, and makes it consistent with the thickness of the busbar. Then rotate the first lead screw 53, and through the two groups of reverse threads on its outer part, push the two push plates 51 to approach each other, so that the push plates 51 push the mounting seats 20 at both ends of the placement groove 11 to move closer to the middle, making the several mounting seats 20 in the middle push and move with the elastic members 22, and making multiple partitions 32 push the busbars to move closer to the middle to complete the clamping and fixing of the busbars. Use parts such as bolts and anchor bolts to reinforce between multiple busbars.

[0046] In the present invention, the adjacent busbars are separated by the partition 32. As the inclination angle of the partition 32 is adjusted, the separation distance between the adjacent busbars can be quickly adjusted, so that the bracket 1 can better adapt to the equidistant separation of busbars with different thicknesses, enhancing the versatility of the equipment. And by driving the partition 32 to gather by the mounting seat 20, after the busbars are separated by the partition 32, the busbars can be quickly clamped and positioned, improving the convenience of fixing the busbars, and then improving the installation efficiency of the busbars.

[0047] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
