Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to an explosion-proof bus duct. Background Art

[0002] The bus duct is a closed metal device composed of copper and aluminum busbars. It has the advantages of small size, compact structure, large transmission current, easy installation and simple maintenance. It is mainly used to transmit electricity, especially in the power distribution system of large buildings, high-rise buildings, factories, hospitals, airports and other places, to transmit electric energy from the low-voltage distribution room to each floor and each area. The bus duct can effectively solve the problems of short transmission distance, small current capacity and susceptibility to environmental influences in traditional cable power transmission, and improve the efficiency and stability of power transmission. The working principle of the bus duct is to use the conductive loop formed by the overlap of copper and aluminum busbars to transmit electric energy from the power source to each electrical equipment. It adopts air insulation and all-copper or aluminum structure, and can operate normally in harsh environments such as high temperature, low temperature, humidity and dirt to ensure stable transmission of electricity.

[0003] During use, the existing explosion-proof bus duct has a relatively thin overall structure and low structural stability, resulting in poor explosion-proof performance, making it difficult to withstand external impacts, having low protection capabilities for internal conductors, and being difficult to dissipate heat, resulting in poor air circulation inside the bus box, which leads to the possibility of explosion or fire due to excessive internal temperature. When a fire occurs outside, it is very easy for flames to enter the bus box when a bus box with heat dissipation holes is provided, thereby reducing the fireproof performance of the bus duct. In addition, when installing the bus box, the interface is not convenient for quick connection and disassembly, which reduces the efficiency of installation. Utility Model Content

[0023] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the reinforcement member 22 includes a reinforcement rib 222 fixed to the outside of the protective shell 21, a frame 221 arranged on the outside of the protective shell 21, and a bolt 223 threadedly connected to the frame 221 and the inside of the reinforcement rib 222; the ventilation member 23 includes a fixing plate 231 arranged on one side of the protective shell 21, and a ventilation hole 232 and a slide groove 238 opened on one side of the fixing plate 231; the ventilation member 23 also includes a rotating shaft 234 fixed to one side of the fixing plate 231, a partition 233 rotating on the outside of the rotating shaft 234, and a torsion spring 235 fixed to one side of the partition 233; the ventilation member 23 also includes a wax block 236 arranged at one end of the torsion spring 235, and a guide block 237 fixed to one side of the partition 233;

[0024] It should be noted that the protective shell 21 is an integrated design, which helps to improve the overall strength. By setting the reinforcement 22, the overall strength of the protective shell 21 is further improved, thereby improving the explosion-proof performance. By setting the ventilation holes 232, the heat dissipation capacity of the conductor 24 in the protective shell 21 is improved, and the possibility of explosion or fire caused by excessive internal temperature due to poor air circulation inside the protective shell 21 is reduced. By setting the partition 233 and the torsion spring 235, it is convenient for the wax block 236 to melt when a fire occurs outside. After the torsion spring 235 loses its limit, the rebound force generated by it drives the partition 233 to rotate along the rotating shaft 234 and is fixed to the partition 233. The guide block 237 on one side follows the sliding, and while sliding along the slide groove 238, the stability of the partition 233 during rotation is improved. The slide groove 238 is semicircular. When the guide block 237 is rotated 180 degrees and presses against the bottom of the slide groove 238, the partition 233 stops rotating. At this time, the partition 233 covers the outside of the ventilation hole 232, isolating the connection between the inside of the protective shell 21 and the outside world, so that the fire cannot enter the inside of the protective shell 21, thereby enhancing the fireproof performance of the bus duct. By setting the sealing groove 25, it is convenient to connect the protective shell 21 with the connecting box 31. The sealing gasket 38 fixed on one side of the connecting box 31 presses against the inner side of the sealing groove 25 to seal the interface.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, the connecting member 33 includes a sliding button 331 sliding inside the first connecting block 32, a push rod 332 fixed to one side of the sliding button 331, and a first spring 333 sleeved on the outside of the push rod 332; the connecting member 33 also includes a sliding block 334 fixed to one end of the push rod 332, a fixing block 335 arranged on one side of the sliding block 334, and a clamping block 336 fixed to one side of the first connecting block 32; the limiting member 35 includes a limiting hole 351 and a clamping groove 355 opened inside the second connecting block 34, a sliding rod 352 sliding inside the limiting hole 351, a second spring 353 sleeved on the outside of the sliding rod 352, and a limiting block 354 fixed to one end of the sliding rod 352;

[0026] It should be noted that: by setting the sliding button 331, it is convenient to push the push rod 332 to slide and thus drive the slider 334 to move forward. By setting the first spring 333, it is convenient to return the push rod 332 to its original position through elastic force after moving forward. By setting the fixing block 335, it is convenient to fix the first connecting block 32 and the second connecting block 34 when the limit block 354 limits it. By setting the second spring 353 and the limiting hole 351, it is convenient for the slider 334 to move forward along the arc of the surface of the limit block 354, and the limit blocks 354 on both sides are squeezed backward, so that the fixing block 335 is out of the locked state, thereby realizing the quick connection and disassembly between the protective shell 21 and the connecting box 31, thereby improving the installation efficiency. By setting the guide block 36 and the guide groove 37, it is convenient to provide guidance for both sides during installation and connection, guide the connection, ensure that the sealing gasket 38 is stuck in the sealing groove 25, and at the same time strengthen the structural strength of the connection.

[0027] Working principle: During installation, first align the guide block 36 with the guide groove 37 for preliminary connection, then the card block 336 is inserted into the card groove 355, and after the fixed block 335 enters the second connecting block 34, it moves upward along the curvature of the surface of the limit block 354, and the limit block 354 is squeezed to slide backward. After the fixed block 335 reaches the top of the limit block 354, the second spring 353 pushes the limit block 354 to reset through inertia and is stuck at the bottom of the fixed block 335, thereby limiting it. When disassembly is required, first push the slide button 331 upward, and the push rod 332 slides to drive the slider 334 to move forward. When the slider 334 moves forward along the curvature of the surface of the limit block 354, the limit blocks 354 on both sides are squeezed backward, thereby causing the fixed block 335 to be out of the locked state. , thereby realizing quick connection and disassembly between the protective shell 21 and the connection box 31, improving the efficiency of installation. When a fire occurs in the external environment, the wax block 236 is melted by heat, and after the torsion spring 235 loses its limit, the rebound force generated by it drives the partition 233 to rotate along the rotating shaft 234, and the guide block 237 fixed on one side of the partition 233 follows and slides, while sliding along the slide groove 238, improving the stability of the partition 233 during rotation. The slide groove 238 is semicircular. When the guide block 237 is rotated 180 degrees and abuts against the bottom of the slide groove 238, the partition 233 stops rotating. At this time, the partition 233 covers the outside of the ventilation hole 232, isolating the connection between the inside of the protective shell 21 and the outside world, so that the fire cannot enter the inside of the protective shell 21, thereby enhancing the fireproof performance of the bus duct.
