Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a fire-resistant bus duct device. Background Art

[0002] Bus duct is a device used for power transmission and distribution, commonly used in commercial buildings and industrial facilities. The main function of bus duct is to provide an efficient and reliable power transmission channel.

[0003] A Chinese patent with the public number CN219436593U discloses a fire-resistant bus duct device, which belongs to the field of bus duct technology. The bus duct shells of the two bus duct components of the fire-resistant bus duct device are respectively fixedly connected to the two ends of the connector shell of the connector component, so that the fire-resistant bus duct device forms a whole, and the two bus duct components and the connector component are fire-proofed, thereby ensuring that the bus duct component can play an effective fire-proofing effect in the event of a fire.

[0004] However, the fire-resistant bus duct device of the above scheme is more troublesome to assemble the various components during use, which is inconvenient for maintenance and inspection. In addition, under high-load operation, there is still a problem of insufficient heat dissipation, which leads to overheating and thus affects the safety of the equipment. Therefore, a fire-resistant bus duct device is proposed to solve the above problems. Utility Model Content

[0005] Based on the existing fire-resistant bus duct device, it is relatively troublesome to assemble various components during use, and there is still a technical problem of insufficient heat dissipation under high load operation. The utility model proposes a fire-resistant bus duct device.

[0006] The utility model proposes a fire-resistant bus duct device, which includes a bus duct body and a bus duct connector. The outside of the bus duct body and the bus duct connector are both provided with a protective device, and the protective device includes a clip and a fixing block. The fixation of the clip and the fixing block protects the bus duct body and the bus duct connector.

[0007] Preferably, the protection device further comprises a protective shell, and a side plate is fixedly mounted on the outer surface of the protective shell.

[0008] Through the above technical solution, by installing side panels on the protective shell to fix the protective shell, the protective shell is fixed to the outside of the bus trough body and the bus trough connector. The bus trough body and the bus trough connector can be directly placed in the protective shell, and their sides can be protected, thereby protecting the bus trough body and the bus trough connector.

[0009] Preferably, the outer surface of the protective shell is hinged with a shell cover through a pin shaft, the inner wall of one end of the shell cover is slidably inserted into the outer surface of the buckle, the outer surface of the protective shell is fixedly connected to one end of the fixed block, and a card hole is provided on the outer surface of the fixed block, and the inner wall of the card hole is slidably inserted into the outer surface of the buckle.

[0010] Through the above technical solution, the protective shell is easily installed on the outside of the bus trough by hingedly connecting the shell cover. By installing a clip at one end of the shell cover, the clip is slidably plugged into the fixed block on the protective shell, so that the protective shell can be easily disassembled, thereby improving the efficiency of maintenance, inspection and replacement of internal components.

[0011] Preferably, a heat sink is fixedly mounted on the upper surface of the bus trough body, and the heat sink is located inside the protective shell.

[0012] Through the above technical solution, by installing heat sinks on the upper surface of the bus trough body, the bus trough body can be kept within a safe operating temperature range. The problem of dust and dirt accumulation caused by the exposure of the heat sink inside the protective shell affecting its heat dissipation performance is reduced, thereby reducing the risk of failure due to overheating.

[0013] Preferably, the material of the protective shell is Q235 plate, the outer surface of the protective shell is coated with epoxy resin, and the gap between the protective shell and the busbar trough body is filled with fireproof cotton.

[0014] Through the above technical solution, by using Q235 plates, Q235 plates have good wear resistance. Compared with other high-strength steels, the production cost of Q235 is low and it is suitable for large-scale applications. Epoxy resin is coated on the outer surface of the protective shell. Epoxy resin is used as a fire-retardant coating for fire protection. By filling the gap between the protective shell and the busbar duct with fire-retardant cotton, it can further prevent the spread of flames and delay the temperature rise, thereby protecting the internal electrical equipment from the threat of fire.

[0015] Preferably, conductive copper bars are fixedly connected to both sides of the bus duct body, the outer surfaces of the conductive copper bars are wrapped with rock wool, and the outer surfaces of the conductive copper bars are slidably plugged into the outer surfaces of the bus duct connectors.

[0016] Through the above technical solution, by wrapping the outer surface of the conductive copper busbar with rock wool, the conductive copper busbar can be effectively isolated from the surrounding environment, preventing the risk of short circuit and electric shock, and effectively stopping the spread of flames, providing additional safety protection. Especially in high temperature or fire conditions, it can delay the temperature rise and protect the equipment from damage. The conductive copper busbar and the bus duct connector are slidably plugged in, thereby facilitating the installation and removal between the conductive copper busbar and the bus duct connector, reducing the complexity of maintenance.

[0017] The beneficial effects of the present invention are:

[0018] 1. The bus trough body and the bus trough connector are protected by providing a protective device. The side panels are installed on the protective shell to fix the protective shell. The protective shell is fixed to the outside of the bus trough body and the bus trough connector. The bus trough body and the bus trough connector can be directly placed in the protective shell while their sides are protected, thereby protecting the bus trough body and the bus trough connector. The shell cover is hinged to facilitate the installation of the protective shell on the outside of the bus trough body. A buckle is installed at one end of the shell cover, and the buckle is slidably plugged into the fixed block on the protective shell, so that the protective shell can be easily disassembled, thereby improving the efficiency of maintenance, inspection and replacement of internal components, and solving the technical problem of the existing fire-resistant bus trough device that it is more troublesome to assemble various components during use.

[0019] 2. By setting up heat sinks, the bus duct body is kept within a safe operating temperature range. The heat sink located inside the protective shell reduces the problem of dust and dirt accumulated due to exposure of the heat sink affecting its heat dissipation performance, thereby reducing the risk of failure due to overheating. It solves the technical problem of insufficient heat dissipation during use of existing fire-resistant bus duct devices, which affects the safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The outside of the bus duct body 1 and the bus duct connector 2 are both provided with a protective device, which includes a clip 3 and a fixing block 4. The fixation of the clip 3 and the fixing block 4 protects the bus duct body 1 and the bus duct connector 2.

[0027] In order to protect the bus trough body 1 and the bus trough connector 2, the protection device also includes a protective shell 5, and the outer surface of the protective shell 5 is fixedly installed with a side panel 6.

The bus trough body 1 and the bus trough connector 2 can be directly placed in the protective shell 5, and their sides can be protected, thereby protecting the bus trough body 1 and the bus trough connector 2.

[0028] In order to facilitate the disassembly of the protective shell 5, the outer surface of the protective shell 5 is hinged with a shell cover 7 through a pin shaft, and the inner wall of one end of the shell cover 7 is slidably inserted into the outer surface of the buckle 3. The outer surface of the protective shell 5 is fixedly connected to the fixed block 4, and a card hole 8 is provided on the outer surface of the fixed block 4. The inner wall of the card hole 8 is slidably inserted into the outer surface of the buckle 3. By hingedly connecting the shell cover 7, the protective shell 5 is conveniently installed on the outside of the bus trough 1. By installing the buckle 3 at one end of the shell cover 7, the buckle 3 is slidably inserted into the fixed block 4 on the protective shell 5, so that the protective shell 5 can be easily disassembled, thereby improving the efficiency of repairing, inspecting and replacing internal components.

[0029] By setting up a protective device, the bus trough body 1 and the bus trough connector 2 are protected. By installing a side panel 6 on the protective shell 5 to fix the protective shell 5, the protective shell 5 is fixed to the outside of the bus trough body 1 and the bus trough connector 2. The bus trough body 1 and the bus trough connector 2 can be directly placed in the protective shell 5, and their sides can be protected, thereby protecting the bus trough body 1 and the bus trough connector 2. The shell cover 7 is hinged to facilitate the installation of the protective shell 5 on the outside of the bus trough body 1. By installing a buckle 3 at one end of the shell cover 7, the buckle 3 is slidably plugged into the fixed block 4 on the protective shell 5, so that the protective shell 5 can be easily disassembled, thereby improving the efficiency of maintenance, inspection and replacement of internal components, and solving the technical problem of the existing fire-resistant bus trough device that it is more troublesome to assemble various components during use.

[0030] In order to reduce the risk of failure of the bus trough body 1 due to overheating, a heat sink 9 is fixedly installed on the upper surface of the bus trough body 1, and the heat sink 9 is located inside the protective shell 5. By installing the heat sink 9 on the upper surface of the bus trough body 1, the bus trough body 1 can be kept within a safe operating temperature range.

This solves the technical problem of the existing fire-resistant bus duct device that insufficient heat dissipation will occur during use, affecting the safety of the equipment.

[0032] In order to reduce production costs, the material of the protective shell 5 is Q235 plate, and the outer surface of the protective shell 5 is coated with epoxy resin. The gap between the protective shell 5 and the bus trough body 1 is filled with fireproof cotton 10. By using Q235 plate, Q235 plate has good wear resistance. Compared with other high-strength steels, and the production cost of Q235 is low, it is suitable for large-scale application. Epoxy resin is coated on the outer surface of the protective shell 5. Epoxy resin is used as a fireproof coating for fire protection. By filling the gap between the protective shell 5 and the bus trough body 1 with fireproof cotton 10, the spread of flames can be further prevented, and the temperature rise can be delayed, thereby protecting the internal electrical equipment from the threat of fire.

Especially in high temperature or fire conditions, it can delay temperature rise and protect equipment from damage. The conductive copper busbar 11 is slidably plugged into the bus duct connector 2, thereby facilitating the installation and disassembly between the conductive copper busbar 11 and the bus duct connector 2, reducing the complexity of maintenance.

[0034] Working principle: Slide the buckle 3 on the shell cover 7 hinged on the protective shell 5 into the card hole 8 of the fixed block 4 to protect the bus trough body 1 and the bus trough connector 2, and can be quickly installed and disassembled.
