Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a fire protection power supply and distribution bus duct. Background Art

[0002] Busbar ducts are enclosed conductive systems used for transmitting and distributing high currents. They are widely used in industrial and commercial locations, such as factories, commercial centers, high-rise buildings, generator rooms, data centers, and lighting systems. They are primarily used in low-voltage power transmission trunk projects and can carry high currents of hundreds or even thousands of amperes to meet a variety of power needs.

[0003] In order to avoid the impact of fire, a fireproof cover is often installed on the outside of the bus duct to isolate the fire source, so that the bus duct and its internal components can be protected. However, fire will also generate a large amount of heat. Even if a fireproof cover is installed on the outside of the bus duct, the heat will be transferred to the bus duct and its internal components through the fireproof cover, which will affect the normal use of related components. In addition, the existing fireproof cover is often fixed to the outside of the bus duct by bolts. When the bus duct and its internal components need to be operated, multiple sets of bolts need to be unscrewed to achieve the removal of the fireproof cover, which affects the maintenance efficiency of the bus duct. To this end, a fire-fighting power supply and distribution bus duct is proposed as an improvement. Utility Model Content

[0007] The upper and lower guard plates are each provided with an installation cavity, wherein a cooling pipe network filled with cooling water is provided in the installation cavity, and the upper and lower guard plates are each provided with an insulation cavity, and the lower guard plate is rotatably connected to a fireproof cover covering the outside of the socket;

[0008] The lower end of the upper guard plate and the upper end of the lower guard plate are both fixedly connected with an insertion strip, and a locking groove is provided on the insertion strip. The upper end of the upper guard plate and the lower end of the lower guard plate are both provided with a slot, and a dial plate is provided in the slot. The bottom end of the dial plate is fixedly connected with a locking block, and a spring is provided between the dial plate and the inner wall of the slot.

[0009] Preferably, from any of the above schemes, the upper guard plate and the lower guard plate both adopt an L-shaped structure, and the thermal insulation pad also adopts an L-shaped structure and is fixedly connected to the inner walls of the upper guard plate and the lower guard plate.

[0010] Preferably, any of the above solutions has a plurality of sockets which are evenly arranged along the length of the bus duct.

[0011] Using this technical solution, bus ducts are used in low-voltage power transmission trunk projects and can carry high currents of hundreds or even thousands of amperes to meet a variety of power needs. Upper and lower guard plates surround the bus duct, protecting it and isolating it from external fire sources, preventing fires from affecting the bus duct and its internal components. Thermal insulation pads are installed between the bus duct and the upper and lower guard plates. These pads effectively isolate the heat on both sides, preventing external heat from excessively affecting the bus duct's operating state. Sockets allow power cords for external appliances to be connected to the bus duct, providing power to these appliances.

[0012] Preferably, from any of the above solutions, the installation cavity and the heat insulation cavity both adopt an L-shaped structure, and the cooling pipe network is fixedly connected in the installation cavity.

[0013] Preferably, any of the above solutions is that the heat insulation cavity is arranged inside the installation cavity, and the top end of the fireproof cover is rotatably connected to the lower guard plate via a rotating shaft.

[0014] The above technical solution: The installation cavity provides space for the cooling pipe network, which is filled with cooling water. Cooling water has a high heat absorption ratio and can absorb a large amount of heat. In the event of an external fire, the heat transferred to the upper and lower guard plates can be absorbed by the cooling water, thereby reducing the heat transferred to the insulation pad. The cooling pipe network can be fixed in the installation cavity by gluing or other means to prevent displacement of the cooling pipe network. The fireproof cover covers the outside of the socket, isolating it from external fire sources and preventing them from affecting the socket.

[0015] Preferably, any of the above solutions has the insertion strips adopting a rectangular structure, the slots adopting a Z-shaped structure, and there are a plurality of the insertion strips and slots, which are evenly arranged along the length direction of the upper guard plate and the lower guard plate.

[0017] Using this technical solution, inserts and slots connect the upper and lower guard plates. A lever and a locking block lock the inserts, locking the upper and lower guard plates together. A spring elastically supports the lever, allowing it to move horizontally to a certain degree in response to external forces, facilitating removal of the upper and lower guard plates when needed. Multiple inserts and slots are evenly spaced along the length of the upper and lower guard plates to ensure locking at all points.

[0018] The utility model comprises a mounting cavity, a cooling pipe network, an insulation cavity, an insert, a locking groove, a slot, a paddle, a locking block, a spring, and other components. In the event of an external fire, heat transferred to the upper and lower guard plates can be largely absorbed by the cooling water, thereby reducing the amount of heat transferred to the insulation pad. The insulation cavity further isolates external heat, improving the protective effect. The insulation pad effectively isolates heat from both sides, preventing external heat from excessively affecting the working state of the bus duct. When the upper and lower guard plates need to be removed, the paddle is moved to disengage the locking block from the locking groove. The insert can then be pulled out of the slot, making removal more convenient and effectively improving the maintenance efficiency of the bus duct. The cooling pipe network can be fixedly connected to the mounting cavity by gluing or other means to prevent displacement of the cooling pipe network. A fireproof cover covers the outside of the socket, isolating it from external fire sources and preventing them from affecting the socket. Several inserts and slots are evenly arranged along the length of the upper and lower guard plates to ensure the locking effect at all points of the upper and lower guard plates.

The upper guard plate 2 and the lower guard plate 3 are each provided with an insulation cavity 8. The lower guard plate 3 is rotatably connected to a fireproof cover 9 covering the outside of the socket 5.

[0028] The lower end of the upper guard plate 2 and the upper end of the lower guard plate 3 are fixedly connected with an insertion strip 11, and a locking groove 12 is provided on the insertion strip 11. The upper end of the upper guard plate 2 and the lower end of the lower guard plate 3 are both provided with a slot 10, and a dial plate 13 is provided in the slot 10.

[0029] Example 1: The upper guard plate 2 and the lower guard plate 3 both adopt an L-shaped structure, and the thermal insulation pad 4 also adopts an L-shaped structure and is fixedly connected to the inner walls of the upper guard plate 2 and the lower guard plate 3. There are several sockets 5 and they are evenly arranged along the length of the bus duct 1. The bus duct 1 is used for low-voltage power transmission trunk line engineering projects and can carry high currents of hundreds of amperes or even thousands of amperes to meet various power needs. The upper guard plate 2 and the lower guard plate 3 surround the outside of the bus duct 1 to protect the bus duct 1 and isolate it from external fire sources to prevent fire from affecting the bus duct 1 and its internal components. A thermal insulation pad 4 is provided between the bus duct 1 and the upper guard plate 2 and the lower guard plate 3. The thermal insulation pad 4 can effectively isolate the heat on both sides to prevent external heat from excessively affecting the working state of the bus duct 1. The socket 5 can be used for connecting the power cord of external electrical appliances to the bus duct 1 to supply power to the external electrical appliances.

[0030] Example 2: The installation cavity 6 and the insulation cavity 8 both adopt an L-shaped structure, and the cooling pipe network 7 is fixedly connected to the installation cavity 6. The insulation cavity 8 is arranged on the inner side of the installation cavity 6, and the top of the fireproof cover 9 is rotatably connected to the lower guard plate 3 through a rotating shaft. The installation cavity 6 provides an installation space for the cooling pipe network 7. The interior of the cooling pipe network 7 is filled with cooling water. The cooling water has a large heat absorption ratio and can absorb a large amount of heat.

A sealing plate is fixedly connected to the top of the selector plate 13, blocking the outer side of the insert 10. The insert 11, in conjunction with the slot 10 and other components, connects the upper and lower guard plates 2 and 3. The selector plate 13, in conjunction with the locking block 14, locks the insert 11, thereby locking the upper and lower guard plates 2 and 3 together. The spring 15 elastically supports the selector plate 13, allowing it to move horizontally to a certain extent when subjected to external forces, facilitating removal of the upper and lower guard plates 2 and 3 when needed. The multiple inserts 11 and slots 10 are evenly spaced along the length of the upper and lower guard plates 2 and 3, ensuring a secure locking effect at all points on the upper and lower guard plates 2 and 3.

[0032] The working principle of this utility model is as follows:

[0033] S1. When a fire occurs outside, the heat transferred to the upper guard plate 2 and the lower guard plate 3 can be largely absorbed by the cooling water, thereby reducing the heat transferred to the thermal insulation pad 4;

[0034] S2, the heat insulation cavity 8 can further isolate the external heat and improve the protection effect. The heat insulation pad 4 can effectively isolate the heat on both sides to prevent the external heat from excessively affecting the working state of the bus duct 1;

[0035] S3. When the upper guard plate 2 and the lower guard plate 3 need to be disassembled, the dial plate 13 is moved to drive the locking block 14 to disengage from the locking groove 12, and then the inserting strip 11 can be pulled out from the slot 10 to achieve disassembly.

[0036] In summary, the fire-fighting power supply and distribution bus duct of the present invention is provided with components such as the installation cavity 6, the cooling pipe network 7, the insulation cavity 8, the insert 11, the locking groove 12, the slot 10, the dial plate 13, the locking block 14, and the spring 15. When a fire occurs outside, the heat conducted to the upper guard plate 2 and the lower guard plate 3 can be absorbed by the cooling water in large quantities, thereby reducing the heat transferred to the insulation pad 4. The insulation cavity 8 can further isolate the external heat and improve the protection effect. The insulation pad 4 can effectively isolate the heat on both sides to prevent the external heat from excessively affecting the working state of the bus duct 1. When it is necessary to remove the upper guard plate 2 and the lower guard plate 3, the dial plate 13 is moved to drive the locking block 14 out of the locking groove 12, and then the insert 11 can be pulled out of the slot 10 to achieve disassembly, which makes disassembly more convenient and can effectively improve the maintenance efficiency of the bus duct.

[0037] The fire-fighting power distribution busbar and cooling network 7 are securely connected within the mounting cavity 6 via gluing or other means to prevent displacement of the cooling network 7. A fireproof cover 9 extends over the exterior of the socket 5, isolating it from external fire sources and preventing them from affecting the socket 5.
