Description

Technical Field

[0001] The utility model relates to a fire-retardant busbar trunking for fire fighting. Background Art

[0002] In the power system, the busbar trunking is an important power transmission device. However, since there are a large number of wires and electrical components inside the busbar trunking, once a fire breaks out, the fire is likely to spread rapidly, posing a serious threat to people's lives and property safety.

[0003] In order to improve the fire prevention performance of the busbar trunking, some busbar trunking products with fire prevention functions have emerged on the market. These products usually achieve the fire prevention function by setting fire prevention materials inside the busbar trunking or installing fire extinguishing devices. However, these products have some deficiencies. For example, the fire prevention performance of some fire prevention materials is not ideal and is prone to failure in a fire; some fire extinguishing devices require manual operation and cannot be started in time when a fire breaks out, resulting in the fire not being effectively controlled, unable to quickly cut off the circuit, unable to seal the busbar trunking to a certain extent to prevent the spread of the fire. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and to provide a fire-retardant busbar trunking for fire fighting that can automatically spray fire retardant. Another purpose of the utility model is to provide a fire-retardant busbar trunking for fire fighting that can automatically cut off the circuit in case of fire. Still another purpose of the utility model is to provide a fire-retardant busbar trunking for fire fighting that can automatically seal in case of fire. These purposes of the utility model are achieved as follows:

[0005] A fire-retardant busbar trunking for fire fighting includes a main body and a fire extinguishing unit. A chamber is provided inside the main body. The fire extinguishing unit is arranged on the upper side of the main body. Tracks are provided inside the main body along the sides of the main body. There are two tracks and they are respectively arranged on both sides of the main body. The tracks have downward bends. A cooperating part that cooperates with the track is provided on the track. The cooperating part is connected to a sliding piece. The width of the sliding piece is greater than the width of the chamber. A propulsion cylinder is provided at one end of the track. There are two propulsion cylinders and they are symmetrically arranged inside the chamber. An installation part that cooperates with the propulsion cylinder is provided inside the propulsion cylinder. One side of the installation part is connected to the sliding piece. A blade part is provided on one side of the sliding piece close to the bend. The other end of the installation part is connected to an elastic member. The installation part is also connected to a fixing member. The fixing member includes a buckling part. The buckling part is in a C-shaped structure. The buckling parts are clamped and fixed by relying on the C-shaped structure.

[0006] In order to better achieve the automatic fire extinguishing effect, the material of the valve is tin.

[0007] In order to obtain a stronger rebounding force, the elastic member is a spring, and the material of the elastic member is metal.

[0008] To prevent a single fire extinguishing unit from failing, two such fire extinguishing units are provided.

[0009] To prevent the fixing part from breaking due to temperature influence, the fixing member is made of stainless steel and the fastening part is made of tin.

[0010] For a better fastening effect and to prevent the fastening from being too tight or too loose and affecting the cutting, the axes between the propulsion cylinders are parallel to each other.

[0011] To better balance the requirements of sealing, fire prevention and flexibility, the sliding piece is made of metal foil.

[0012] Advantageous effects: It can quickly spray fire retardant during a fire, effectively inhibit the spread of fire, improve the fire extinguishing efficiency. Quick fire extinguishing can reduce the damage to the busbar trunking and surrounding equipment caused by the fire, reduce property losses, and timely fire extinguishing helps to reduce the long-distance line losses caused by the fire.

[0013] Automatically cutting off the line can prevent the fire from spreading to other areas through the wires, reduce the occurrence probability of more electrical accidents, ensure the safety of personnel and equipment. Through the sealing of the sliding piece, the effect of the fire retardant is strengthened, the oxygen circulation is reduced, which helps to better extinguish the fire and prevent the spread of the fire.

[0018] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0019] In this embodiment:

[0020] Please refer to Figures 1-3, A flame-retardant busway for fire protection, comprising a main body 1 and a fire extinguishing unit 2. A chamber 4 is provided inside the main body 1. The fire extinguishing unit 2 is arranged on the upper side of the main body 1. The fire extinguishing unit 2 includes a valve. The valve is made of a metal with a melting point between 200 and 400 degrees Celsius. Inside the main body 1, there are tracks 3 arranged along the sides of the main body 1. There are two tracks 3 and they are respectively arranged on both sides of the main body 1. The tracks 3 have downward bends. A mating portion 6 that mates with the track 3 is provided on the track 3. The mating portion 6 is connected to a sliding piece 5. The width of the sliding piece 5 is greater than the width of the chamber 4. One end of the track 3 is provided with a propulsion cylinder 9. There are two propulsion cylinders 9 and they are symmetrically arranged inside the chamber 4. An installation portion 11 that mates with the propulsion cylinder 9 is provided inside the propulsion cylinder 9. One side of the installation portion 11 is connected to the sliding piece 5. A blade portion 7 is provided on one side of the sliding piece 5 close to the bend. The other end of the installation portion 11 is connected to an elastic member 10. The installation portion 11 is also connected to a fixing member 13. The fixing member 13 includes a fastening portion 12. The fastening portion 12 has a C-shaped structure. The fastening portions 12 are clamped and fixed by relying on the C-shaped structure.

[0021] The valve is made of tin. The elastic member 10 is made of metal. There are two fire extinguishing units 2. The fixing member 13 is made of stainless steel. The fastening portion 12 is made of tin. The axes between the propulsion cylinders 9 are parallel to each other. The sliding piece 5 is made of metal foil, such as aluminum foil.

[0022] The following is the operating principle:

[0023] When a fire occurs, the temperature inside this device will rise under the influence of the flame. When the temperature rises to a certain extent, the structure of the fastening portion 12 will become soft, resulting in its loosening. Then, the sliding piece 5 will cut off the circuit 8 under the push of the elastic member 10. At the same time, the valves of the two fire extinguishing units 2 arranged on the upper part of the main body 1 will also become soft due to the temperature and finally burst due to pressure, releasing the fire retardant. When one of the fire extinguishing units 2 fails, there is another one as a backup, enhancing the reliability.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
