Description

Technical Field

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

[0002] Modern high-rise buildings and large workshops require enormous amounts of electrical energy. To handle the hundreds or even thousands of amperes of current required to handle this massive load, reliable transmission equipment is essential, and busbar systems are an excellent choice. Busbar trunking systems are highly efficient distribution devices, particularly suited to the economical and efficient wiring needs of increasingly tall buildings and large-scale factories. Currently, busbar trunking systems, both domestically and internationally, typically utilize steel or copper-aluminum composite casings. These are not only bulky and prone to corrosion, but also aesthetically pleasing, with poor heat dissipation and inconvenient installation and maintenance. Furthermore, traditional busbar trunking has poor fire protection and resistance, making it easily ignited by fire, leading to power outages and significantly hindering fire rescue efforts.

[0003] Currently, a Chinese utility model with the publication number CN218482629U discloses a fire-resistant bus duct, comprising a housing, a fire-resistant assembly disposed on the housing, a buffer mechanism disposed within the housing, a bus duct body disposed on the buffer mechanism, the fire-resistant assembly comprising a flame-retardant layer disposed on the housing, a fire-resistant layer disposed on the flame-retardant layer, and a fireproof layer disposed on the fireproof layer. The utility model improves the fire resistance and fireproofing capabilities of the fire-resistant bus duct by including the fire-resistant assembly, and provides a buffer mechanism to provide a buffering capacity for the bus duct body, preventing damage to the bus duct body from collisions.

[0004] The fire retardancy of the bus duct is average and cannot provide better fire protection performance for the bus duct. At the same time, in the buffering of the bus duct, the spring tends to increase the movement potential energy of the bus duct, and the buffering protection is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a fire-resistant and flame-retardant bus duct, which has the advantages of improving the fire resistance of the bus duct and at the same time providing a buffering and protective function for the bus duct.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a fire-retardant bus duct, comprising a bus duct body, wherein the surfaces of the bus duct body are respectively provided with shell part 1 and shell part 2, the top and bottom of the bus duct body are bolted with connecting plates, one side of the connecting plate is fixedly installed with a mounting block, one end of the mounting block is rotatably connected to a connecting rod through a bearing, one end of the connecting rod is rotatably connected to a slider through a bearing, a damper is provided on one side of the slider, a spring 1 is sleeved on the surface of the damper, a socket is provided on one side of the shell part 2, the interior of the socket is filled with a plug, a movable plate is fixedly installed on one end of the plug, and spring 2 fixedly connected to the interior of the shell part 1 is fixedly installed on both ends of one side of the movable plate.

[0007] The above technical solution is adopted: when using the bus duct, the bus duct surface is preferentially installed with housing member 1 and housing member 2, and bolts are used in conjunction with mounting plate 1 for installation and use. Mounting plate 1 is used to install and fasten housing member 1 and housing member 2, while mounting plate 2 is used to fasten housing member 1 and housing member 2 and the adjacent housing member 1 and housing member 2. The connecting plate is used to support and fix the bus duct body. When external vibration causes housing member 1 and housing member 2 to shake, the movement of the mounting block can cause the angle of the connecting rod to change. The connecting rod will push the slider, and the damper and spring 1 will cooperate with the force of the slider movement to buffer, thereby preventing the buffer from affecting the bus duct, improving the protection effect of the bus duct, and preventing the bus duct from shaking and causing unstable connections at the joints. In addition, in the event of a fire indoors, the fire-retardant coating will increase the flame retardancy of the surfaces of housing member 1 and housing member 2. At the same time, at the initial stage of installation of the bus duct, inert gas is poured into the shell part 1 and the shell part 2, and the external gas input pipe is inserted into the socket and presses against the plug, so that the plug is separated from the inside of the socket, and the plug and the movable plate move. The guide rod cooperates with the movement of the movable plate to guide, and the limit block prevents the movable plate from slipping on the surface of the guide rod. At the same time, the spring 2 extends. At this time, inert gas is input into the shell part 1 and the shell part 2 through the external pipe. In subsequent fires, the inert gas makes the bus duct flame retardant, thereby improving the protection effect of the bus duct.

[0008] The present invention is further configured such that the interiors of the housing member 1 and the housing member 2 are both provided with sliding grooves for cooperating with the sliding of the slider.

[0009] The above technical solution is adopted: the sliding groove is used in conjunction with the slider for sliding.

[0015] Adopt the above technical solution: use bolts to cooperate with the mounting plate 1 for installation and use.

[0016] The present invention is further configured such that positioning rods are fixedly mounted on both sides of the top of the first shell member, and positioning holes for plugging in with the positioning rods are provided on both sides of the bottom of the second shell member.

[0017] By adopting the above technical solution, the positioning installation between the shell part 1 and the shell part 2 can be ensured through the mutual cooperation between the positioning rod and the positioning hole.

[0018] The utility model is further configured such that the interior of the spring 2 is sleeved with a guide rod fixedly connected to the interior of the shell part 1, one end of the guide rod passes through one side of the movable plate and is fixedly installed with a limit block, and the surfaces of the shell part 1 and the shell part 2 are both adhered with a fire-retardant coating.

[0019] The above technical solution is adopted: the guide rod is used to guide the movement of the shift plate, the limit block prevents the shift plate from slipping on the surface of the guide rod, and the fire-retardant coating will increase the flame retardancy of the surface of shell part 1 and shell part 2.

[0020] The present invention is further configured such that sealing strips are fixedly adhered to the opposing surfaces of the shell component 1 and the shell component 2, and sealing rings are fixedly adhered to both ends of the shell component 1 and the shell component 2.

[0021] The above technical solution is adopted: the sealing strip is used to ensure the sealing of both sides of the shell part 1 and the shell part 2, while the sealing ring is used to ensure the sealing of the shell part 1 and the two ends of the shell part.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. In the use of the bus duct of the present invention, it is preferred to install the housing part 1 and the housing part 2 on the surface of the bus duct, and use the bolts in conjunction with the mounting plate 1 for installation. The connecting plate is supported and fixed in conjunction with the bus duct body. When external vibrations cause the housing part 1 and the housing part 2 to shake, the movement of the mounting block can cause the angle of the connecting rod to change. The connecting rod will push the slider, and the damper and spring 1 will cooperate with the force of the slider to buffer. This can prevent the buffer from affecting the bus duct, improve the protection effect of the bus duct, and prevent the bus duct from shaking and causing unstable connections at the joints.

[0024] 2. In the event of a fire indoors, the fire-retardant coating of the present invention increases the flame retardancy of the surfaces of the first and second shells. At the same time, inert gas is injected into the first and second shells during the initial installation of the bus duct. An external gas input pipe is inserted into the socket and presses against the plug, causing the plug to disengage from the socket. The plug and the shift plate move, and the second spring extends. At this point, inert gas is introduced into the first and second shells through the external pipe. In subsequent fires, the inert gas imparts flame retardancy to the bus duct, enhancing its protective effect. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, inert gas is injected into housing parts 1 2 and 2 3 during the initial installation of the bus duct. The external gas input pipe is inserted into the socket 18 and presses against the plug 19, causing the plug 19 to disengage from the socket 18. The plug 19 and the movable plate 20 move, and the guide rod 21 cooperates with the movement of the movable plate 20 to guide it. The limit block 23 prevents the movable plate 20 from slipping on the surface of the guide rod 21. At the same time, the spring 2 22 extends.
