Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a fire-resistant and waterproof busbar structure. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all sectors has increased rapidly, especially with the appearance of high-rise buildings and large factory workshops. Traditional cables can no longer meet the requirements of high-current transmission systems. Busbar trunking, with its high efficiency, flexibility and safety, has gradually become a substitute for wires and cables and has been widely used in indoor low-voltage power transmission trunk line projects. With the continuous growth of electricity consumption in my country and the continuous progress of power technology, the busbar trunking market will usher in a broader development space. In the future, busbar trunking will develop towards a more intelligent, green and efficient direction, providing strong support for the upgrading of the power system.

[0003] Busbar trunking, as a key component in modern power distribution systems, plays an irreplaceable role in power transmission and distribution due to its high efficiency, flexibility, and safety. However, in current practical applications, some busbar trunking systems have poor waterproofing and fire resistance. If the fire resistance of the busbar trunking does not meet the standards, this safety hazard will persist for a long time and may cause a fire at any time due to external factors such as high temperature or short circuit. Water entering the busbar trunking will cause a decrease in its insulation performance, increasing the risk of short circuits. The insulation layer of the busbar trunking that has been exposed to moisture for a long time is prone to aging, further reducing its insulation performance and increasing the probability of electrical faults. Utility Model Content

[0004] The purpose of this invention is to provide a fire-resistant and waterproof busbar structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-resistant and waterproof busbar structure, including a first outer shell, and further comprising:

[0006] The second outer shell is installed at one end of the first outer shell. The inner wall of the first outer shell is equipped with two sets of support frames. The inner walls of the two sets of support frames are fixed with mounting rods. The outer side of the mounting rods is provided with mounting blocks. The inner wall of the mounting blocks is equipped with conductive bars. The two sides of the conductive bars are provided with heat insulation plates.

[0007] A first protective shell is fixed to one end of a first outer shell, and a second protective shell is inserted into the outer side of the first protective shell. A connector strip is fixed to one end of the first protective shell, and a connector groove is provided on the inner wall of the second protective shell.

[0008] Preferably, the inner wall of the first protective shell is provided with a fixing rod for fixing the first protective shell and the second protective shell, and connecting plates are fixed on both sides of the second protective shell.

[0009] Preferably, a fixing frame is installed on the outer side of the first housing, and a protective plate is rotatably connected to the outer side of the fixing frame.

[0010] Preferably, the inner walls of both the first and second outer shells are fixed with four sealing strips, and the inner wall of the protective plate is rotatably connected with a first bolt, with the outer side of the first bolt threadedly connected to the inner wall of the second outer shell.

[0011] Preferably, the top of both the first and second outer shells is fixed with a fixing block, and the inner wall of the fixing block is threaded with two sets of second bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, by setting up a support frame and mounting rod, allows the conductive busbar to be easily moved away from the outer casing in the event of a fire, thereby preventing the heat source of the outer casing from being conducted to the conductive busbar. The heat insulation plate can isolate the heated outer casing from the conductive busbar, preventing damage to the two sides of the conductive busbar with larger contact surfaces with air after the outer casing heats up. The plug strip and plug slot are used together to seal the connection of the busbar trunking, thereby preventing the insulation layer of the conductive busbar at the interface from aging due to moisture.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a fire-resistant and waterproof busbar structure includes a first outer shell 1, a second outer shell 2 installed at one end of the first outer shell 1, two sets of support frames 3 installed on the inner wall of the first outer shell 1, mounting rods 4 fixed on the inner walls of the two sets of support frames 3, mounting blocks 5 provided on the outer side of the mounting rods 4, conductive bars 6 installed on the inner wall of the mounting blocks 5, and heat insulation plates 7 provided on both sides of the conductive bars 6.

[0025] The first outer shell 1 and the second outer shell 2 can provide simple protection for the conductive busbar 6, preventing foreign objects from damaging it and isolating it from open flames. The support frame 3, the mounting rod 4, and the mounting block 5 work together to support and limit the conductive busbar 6, preventing it from tilting and suspending it in the air, thereby reducing heat conduction from the outer shell to the conductive busbar 6 in the event of a fire. The heat insulation board 7 is existing technology, manufactured using inorganic refractory nanopowder technology. By setting up a series of barriers with a spacing smaller than the mean free path of gas molecules, it forms a near-vacuum state of pores, thereby preventing the thermal movement of gas molecules. Therefore, this case will not elaborate further.

[0026] A first protective shell 8 is fixed to one end of the first outer shell 1, a second protective shell 9 is inserted into the outside of the first protective shell 8, a connector strip 10 is fixed to one end of the first protective shell 8, and a connector groove 11 is opened on the inner wall of the second protective shell 9.

[0027] The combined use of the first protective shell 8 and the second protective shell 9 can conveniently protect the interface of the conductive bus 6, preventing moisture and open flame from damaging the interface of the conductive bus 6. The combined use of the plug strip 10 and the plug groove 11 can conveniently prevent moisture from damaging the insulation layer, thereby reducing the insulation performance and increasing the probability of electrical faults. The plug strip 10 and the plug groove 11 should be made of rubber and need to be tightly fitted.

[0028] The inner wall of the first protective shell 8 is provided with a fixing rod 12 for fixing the first protective shell 8 and the second protective shell 9. Both sides of the second protective shell 9 are fixed with connecting plates 13.

[0029] The fixing rod 12 and the connecting plate 13 can prevent the connection between the first protective shell 8 and the second protective shell 9 from becoming loose, and at the same time improve the sealing performance of the plug strip 10 and the plug groove 11, thereby reducing the probability of electrical failure.

[0030] A fixing frame 14 is installed on the outer side of the first outer shell 1, and a protective plate 15 is rotatably connected to the outer side of the fixing frame 14.

[0031] The fixing frame 14 and the protective plate 15 are rotatably connected, so the protective plate 15 can be opened and closed easily when needed. The protective plate 15 and the sealing strip 16 are both made of rubber. The setting of the protective plate 15 further improves the moisture resistance at the interface, thereby further reducing the probability of electrical failure. Similarly, the double protection can reduce heat conduction, thereby further improving the fire resistance at the interface.

[0032] Four sealing strips 16 are fixed to the inner walls of both the first outer shell 1 and the second outer shell 2. The inner wall of the protective plate 15 is rotatably connected to the first bolt 17, and the outer side of the first bolt 17 is threadedly connected to the inner wall of the second outer shell 2.

[0033] The first bolt 17 can fix the protective plate 15, thereby improving the sealing performance at the joint between the protective plate 15 and the sealing strip 16, and further improving the waterproof performance at the interface.

[0034] The top of both the first outer shell 1 and the second outer shell 2 are fixed with a fixing block 18, and the inner wall of the fixing block 18 is threaded with two sets of second bolts 19.

[0035] The use of the fixing block 18 and the second bolt 19 together can facilitate the connection between the first outer shell 1 and the second outer shell 2, thereby improving the robustness of the interface and preventing the internal conductive busbar 6 from being damaged by external forces or foreign objects.

[0036] Fixing bolts 20 are installed on the outer side of the mounting rod 4, and the number of fixing bolts 20 corresponds one-to-one with the number of mounting blocks 5. Support blocks 21 are fixed on the inner wall of the mounting rod 4, and the outer side of the fixing bolts 20 is threadedly connected to the inner wall of the support blocks 21.

[0037] The use of fixing bolt 20 and support block 21 can provide a fulcrum for the installation of mounting block 5, thereby facilitating the vertical placement of conductive busbar 6 in the air, reducing the impact of heat conduction from the outer casing on conductive busbar 6 in the event of a fire, and thus improving the heat resistance of conductive busbar 6.

[0038] The inner wall of the support frame 3 is fixed with a connecting rod 22 for installing the heat insulation board 7.

[0039] The connecting rod 22 facilitates the installation of the heat insulation plate 7, thereby further reducing the heat conduction from the outer shell to the conductive busbar 6 and improving the heat resistance of the conductive busbar 6.

[0040] Working principle: First, connect the two interfaces. Then, align the connector strip 10 of the first outer shell 1 with the connector slot 11 of the second outer shell 2. Push either outer shell to push the connector strip 10 into the connector slot 11, completing the first step of waterproofing. Then, fix the fixing rod 12 to the connecting plate 13 to prevent loosening at the interface. After fixing, rotate the protective plates 15 on both sides of the first outer shell 1. At this time, the protective plates 15 rotate around the fixing frame 14 until they are in contact with the sealing strip 16. Then, rotate the first bolt 17. The rotation of the first bolt 17 drives the protective plate 15 to rotate, thereby further improving the waterproofing. To improve the sealing of the joint between the protective plate 15 and the sealing strip 16, the second bolt 19 is rotated. The second bolt 19 further reinforces the interface between the first outer shell 1 and the second outer shell 2, thus completing the waterproofing and moisture-proofing. In the event of a fire, the open flame raises the temperature of the outer shell. Since the conductive busbar 6 is not in direct contact with the outer shell, heat conduction is reduced, thus improving the fire resistance of the conductive busbar 6. In addition, the heat insulation plate 7 can reduce the heating rate on both sides of the conductive busbar 6, thereby preventing the temperature on both sides of the conductive busbar 6 with the largest contact area with air from rising too quickly. This allows the staff sufficient time to extinguish the fire.
