[0023] Embodiment 1: A high-voltage cable fixing structure for a busbar cabinet, as Figures 1-4As shown in the figure, it includes a support cabinet body 1 and guide cylinders 2 fixedly arranged on both sides of the support cabinet body 1. The guide cylinders 2 extend out of the inner and outer sides of the support cabinet body 1. A connecting cable 3 is inserted into the guide cylinders 2, and the connecting cable 3 extends into the support cabinet body 1. A limit support ring 5 is arranged on the outer side of the support cabinet body 1 and is located inside the support cabinet body 1. A limit auxiliary ring 7 is rotatably arranged on one side of the limit support ring 5. The connecting cable 3 is located between the limit support ring 5 and the limit auxiliary ring 7. The limit auxiliary ring 7 is inserted into a clamping support groove 9 through an arc-shaped clamping block 8. The arc-shaped clamping block 8 is fixedly arranged at one end of the limit auxiliary ring 7, and the clamping support groove 9 is opened at one end of the limit support ring 5. The outer side of the arc-shaped clamping block 8 is meshed with a rotating gear 10. When the device operates, under the support of multiple guide cylinders 2 on the support cabinet body 1, the connecting cable 3 is inserted and limited, so that it moves between the limit support ring 5 and the limit auxiliary ring 7. Then, by rotating the rotating gear 10, the limit auxiliary ring 7 and the arc-shaped clamping block 8 on one side are driven to move into the clamping support groove 9, achieving the effect of shrinking and fastening the middle connecting cable 3, ensuring the stability of the position of the connecting cable 3 during connection and use. And by setting the racks on the outer side of the limit auxiliary ring 7 and the racks on the outer side of the rotating gear 10 to a longer specification, it is ensured that there is a certain depth of insertion when the rotating gear 10 meshes with the limit auxiliary ring 7, so as to ensure that the limit auxiliary ring 7 can continue to maintain the meshing effect with the rotating gear 10 after contraction, and at the same time, the limit stability effect after the limit auxiliary ring 7 is contracted can be ensured, so that the device can achieve the corresponding fastening and limiting effects according to cables of different diameters.
[0024] As Figures 1-4 shown, a fixed support frame 4 is fixedly connected to the side of the limit support ring 5 away from the limit auxiliary ring 7. The fixed support frame 4 is fixedly arranged inside the support cabinet body 1. A rotating support rod 11 is rotatably arranged inside the fixed support frame 4. The rotating support rod 11 extends out of one side of the fixed support frame 4. The rotating gear 10 is inserted into the rotating support rod 11. Under the support of the support cabinet body 1 for the fixed support frame 4, the stability of the limit support ring 5 during support use is ensured, and under the rotating support of the fixed support frame 4 for the rotating support rod 11, the stability of the rotation adjustment of the rotating gear 10 is improved.
[0025] As Figures 1-4 shown, the limit support ring 5 is rotatably connected to the limit auxiliary ring 7 through a rotating support frame 6. The rotating support frame 6 is fixedly connected to the limit support ring 5. Under the rotating connection of the rotating support frame 6 and the limit auxiliary ring 7, it is ensured that the limit auxiliary ring 7 can move in a shrinking manner under the support of the limit support ring 5, thereby improving the stability during its shrinking and fastening.
[0026] Embodiment 2: A fixed structure for high-voltage cables of a busbar cabinet, as Figures 1-4As shown in the figure, a number of meshing support grooves 12 are provided on the outer side of the rotating support rod 11. The meshing support grooves 12 are meshingly connected with a meshing support frame 13. The meshing support frame 13 is fixedly connected with a rotating adjustment ring 15. The rotating adjustment ring 15 is rotatably connected with a rotating support bolt 14. The rotating support bolt 14 is fixedly arranged on one side of the fixed support frame 4. By rotating the rotating adjustment ring 15 under the limit support of the rotating support bolt 14, the meshing support frame 13 on one side drives the rotating support rod 11 to rotate under the meshing of the meshing support grooves 12, so as to achieve the effect of rotating and adjusting the rotating support rod 11. And by setting a certain gap at the junction of the rotating adjustment ring 15 and the rotating support bolt 14, it is ensured that the rotating adjustment ring 15 can move a certain distance under the limit of the rotating support bolt 14, so as to improve the effect of the meshing support frame 13 on one side rotating repeatedly with the meshing support grooves 12.
[0027] As Figures 1-4 shown in the figure, a limit support block 16 is arranged above the rotating support rod 11. The limit support block 16 is fixedly arranged on one side of the fixed support frame 4. A number of insertion limit blocks 17 are inserted at the upper end of the limit support block 16. The insertion limit blocks 17 extend out of the lower end of the limit support block 16. The insertion limit blocks 17 are inserted into the meshing support grooves 12. By pressing the insertion limit blocks 17 under the support of the limit support block 16, the insertion limit blocks 17 are inserted into the meshing support grooves 12, so as to achieve the effect of clamping and limiting the rotating support rod 11. And by arranging a plurality of connecting strips on the outer side of the insertion limit blocks 17, the insertion limit blocks 17 have a certain buffering and positioning effect when inserted into the limit support block 16, ensuring that the insertion limit blocks 17 will not move under the action of their own gravity.
[0028] Working principle: Through the support of a number of guide cylinders 2 on the support cabinet 1, the connecting cable 3 is inserted and limited, so that it moves between the limit support ring 5 and the limit auxiliary ring 7. Then, by rotating the rotating gear 10, the limit auxiliary ring 7 and the arc-shaped clamping block 8 on one side are driven to move into the clamping support groove 9, so as to achieve the effect of contracting and fastening the connecting cable 3 in the middle, ensuring the stability of the position of the connecting cable 3 when it is connected and used. And by setting the racks on the outer side of the limit auxiliary ring 7 and the racks on the outer side of the rotating gear 10 to be of a longer specification, it is ensured that when the rotating gear 10 meshes with the limit auxiliary ring 7, there is a certain depth of insertion, so as to ensure that the limit auxiliary ring 7 can continue to maintain the meshing effect with the rotating gear 10 after contraction, and at the same time, the limit stability effect after the limit auxiliary ring 7 is contracted can be ensured, so that the device can carry out corresponding fastening and limiting effects according to cables of different diameters.
