Detailed Implementation

[0021] This utility model provides, for example Figures 1-6 An automatic power-off protection busbar trunking system is shown, comprising a housing 1, on which conductive copper busbars 2 are disposed. Multiple conductive copper busbars 2 are provided, each including a first section 4, a second section 5, and a sliding sleeve 6. The first section 4 is fixedly disposed at one end of the housing 1, the second section 5 is fixedly disposed at the other end of the housing 1, and the sliding sleeve 6 is slidably disposed at the connection between the first section 4 and the second section 5. (Refer to...) Figure 5 When the sliding sleeve 6 slides towards the first row of segments 4, the sliding sleeve 6 disengages from the second row of segments 5, causing the first row of segments 4 and the second row of segments 5 to lose connection, thereby achieving the effect of automatic power cut-off, which is convenient for power cut-off in the event of fire, maintenance, etc.

[0022] By setting up structures such as the first row section 4, the second row section 5, and the sliding sleeve 6, the sliding sleeve 6 can achieve the effect of automatic power cut-off, which is convenient for power cut-off in case of fire, maintenance, etc., and improves the utilization efficiency of the bus trunking.

[0023] To prevent mutual interference between adjacent conductive copper busbars 2, an insulating sleeve 7 is fixedly connected to the outside of the sliding sleeve 6, and a connecting rod 8 is fixedly connected between each adjacent insulating sleeve 7. The insulating sleeve 7 and connecting rod 8 are set to prevent mutual interference between adjacent conductive copper busbars 2, and the multiple sliding sleeves 6 form a whole, which can be controlled synchronously.

[0024] A side groove 3 is formed on one outer wall of the housing 1, and a sliding channel 13 is formed on the inner wall of the side groove 3. The sliding channel 13 communicates with the interior of the housing 1. A slider 14 is slidably disposed inside the sliding channel 13, and the slider 14 is fixedly connected to the corresponding insulating sleeve 7. When the slider 14 slides inside the sliding channel 13, it drives the insulating sleeve 7 fixedly connected to the slider 14 to move. Thus, with the cooperation of multiple insulating sleeves 7 and connecting rod 8, multiple sliding sleeves 6 move synchronously. When the sliding sleeve 6 slides towards the first row 4, the sliding sleeve 6 disengages from the second row 5, so that the connection between the first row 4 and the second row 5 is lost.

[0025] A support block 16 is fixedly connected to the inner wall of the side groove 3, and an electric push rod 15 is fixedly connected to the support block 16. The slider 14 is fixedly connected to the telescopic end of the electric push rod 15. Specifically, the electric push rod 15 drives the slider 14 to slide inside the sliding channel 13.

[0026] A sliding plate 10 is provided inside the side channel 3, which fits against the inner wall of the side channel 3 and is fixedly connected to the slider 14. Multiple second through slots 12 are provided on the sliding plate 10. A first through slot 11 is provided on the inner wall of the side channel 3, and the first through slot 11 communicates with the interior of the housing 1. Multiple first through slots 11 are provided, and each first through slot 11 corresponds to a different second through slot 12. During normal operation of the busbar trunking, the multiple first through slots 11 and multiple second through slots 12 are connected, facilitating heat dissipation of the conductive copper busbar 2.

[0027] In actual use, a filter screen or other structure (not shown in the figure) can be installed inside the first channel 11 to prevent impurities from entering the interior of the housing 1.

[0028] When the busbar trunking is not needed, the multiple first through slots 11 and multiple second through slots 12 are staggered one-to-one, and the wall of the slide plate 10 closes the first through slots 11 to ensure that the interior of the housing 1 is sealed.

[0029] Specifically, the telescopic end of the control electric push rod 15 is retracted, causing the slider 14 to slide inside the sliding channel 13, so that the multiple first through slots 11 and multiple second through slots 12 are staggered one by one, and the wall of the slide plate 10 closes the first through slots 11.

[0030] To improve the stability of the sliding plate 10, a sliding groove 17 is provided at the bottom of the side groove 3. A sliding rod 9 is slidably arranged inside the sliding groove 17. The sliding rod 9 is fixedly connected to the sliding plate 10. When the sliding plate 10 slides against the inner wall of the side groove 3, it will drive the sliding rod 9 to slide inside the sliding groove 17, thereby improving the stability of the sliding plate 10.
