The fire-retardant cable in the prior art generally adopts a fire-retardant cable or a fire-resistant cable, and the fire-retardant cable generally only adds a fire retardant into an insulating material and a protective layer material, so that the insulating material and the protective layer material can still burn, bear fire can still be burnt by the fire-retardant cable once a fire breaks out, breakdown and other faults can also happen to the cable during operation to cause the fire, and the fire cannot be effectively flame-retardant and fire-proof.
Therefore, it is necessary to develop a cable with high elasticity, good pressure resistance and good fire-proof effect to solve the above problems.
Disclosure of Invention
The utility model provides a resistance to compression high elasticity cable to improve the crushing resistance and the fire prevention effect of cable.
In order to achieve the purpose, the scheme provides a compression-resistant high-elasticity cable which comprises a wire core, an insulating layer and an armor layer, wherein the wire core, the insulating layer and the armor layer are sequentially arranged from inside to outside, and a buffer layer is arranged between the insulating layer and the armor layer; the nitrogen-containing gas-liquid separator also comprises a support frame, wherein the support frame is a hollow pipe and is internally provided with nitrogen; the fire-extinguishing support is characterized in that a sealing cover is arranged at the outermost end of the support frame, two ends of the sealing cover are in sealing connection with the armor layer, a fire-igniting rod penetrates through the sealing cover, and the ignition point of the fire-igniting rod is lower than the ignition points of the sealing cover and the armor layer.
The utility model discloses a principle and beneficial effect lie in: the support frame plays good supporting role, ensures the stability of whole cable, and the setting of buffer layer, then the compressive strength of effectual increase cable. Be equipped with nitrogen gas in the support frame, cooperating the ignition pole, in case the conflagration breaks out, for the armor, then the ignition pole can take lead the burning, then makes the nitrogen gas blowout in the support frame, plays good fire prevention effect, strives for the time for the rescue personnel. After the fire disaster is over, nitrogen can be continuously added into the support frame, and then a new ignition rod is installed. Compare with traditional cable, this scheme utilization buffer layer has still played good fire prevention effect when having guaranteed the high elasticity of cable.
Further, the sealing cover is I-shaped. The H-shaped sealing cover can be matched with the armor layer to play a good sealing role. Preferably, the lower end of the sealing cover is also arranged to be arc-shaped, so that the supporting frame can be better sealed.
Further, the support frame comprises a central pipe and three branch pipes, wherein the branch pipes are uniformly distributed along the circumference of the central pipe and are communicated with the central pipe. The support frame can contain a lot of nitrogen, single-point combustion is realized, nitrogen at other cables is supplied together, and the fireproof effect is better. In addition, the stability of this structure is also very good.
Further, the buffer layer is a glass fiber buffer layer. The glass fiber buffer layer has good insulation and good buffer effect.
Furthermore, the insulating layer is a polyether-ether-ketone insulating layer, and the insulating property is excellent.
Furthermore, the armor layer is a polytetrafluoroethylene armor layer, and has excellent chemical stability, corrosion resistance, sealing property, high lubrication non-sticking property, electric insulation property, good ageing resistance and good use effect.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the cable comprises a core wire 10, an insulating layer 11, a buffer layer 20, a support frame 30, a sealing cover 31, a fuse rod 32 and an armor layer 40.
As shown in FIG. 1, the cross section of the cable with high elasticity and resistance to pressure in the scheme is basically circular. The most center of the cable is a central tube, 3 branch tubes are communicated with the central tube, and the angle between the branch tubes is 120 degrees. The armor 40 is a polytetrafluoroethylene armor 40 and has a fire resistant coating on its outer surface.
Armor 40 cooperates with support frame 30, divides the cable into three regions, all is equipped with a set of heart yearn unit in every region to fill through glass fiber buffer layer 20. Each group of core wire units comprises three core wires 10 and an insulating layer 11 coated on the surface of each core wire 10, and the insulating layer 11 is a polyether-ether-ketone insulating layer 11 with excellent insulating property.
The outermost ends of the respective branch pipes of the support frame 30 are provided with sealing caps 31. The whole sealing cover 31 is in an I shape, and the clamping grooves at the two ends of the sealing cover are just matched with the armor layer 40, so that the armor layer 40 is clamped on the sealing cover 31 to realize sealing. Corresponding gaskets should also be provided to increase the sealing when necessary. The lower end of the sealing cap 31 is in the form of an arc which can be fitted to the branch pipe to seal it.
In addition, a through hole is formed in the middle of the sealing cover 31, and a fire rod 32 is installed in the through hole. The ignition bar 32 is made of a relatively low ignition point material (the ignition point must be lower than that of the armor 40), such as wood or the fuse of a fireworks firecracker is also possible. Of course, the ignition bar 32 is generally coated with a layer of paraffin or the like to prevent air leakage. Similarly, in order to increase the sealing performance, the ignition rod 32 may be formed in a shape of a tool, and the structure thereof may be referred to that of the sealing cover 31.
In this scheme, support frame 30 plays good supporting role, ensures the stability of whole cable, and the setting of buffer layer 20, then the compressive strength of effectual increase cable. Be equipped with nitrogen gas in support frame 30, cooperating the ignition pole 32, in case the conflagration breaks out, for armor 40, then ignition pole 32 can take the lead the burning, then makes the nitrogen gas blowout in the support frame 30, plays good fire prevention effect, strives for the time for the rescue personnel. After the fire is over, the nitrogen can be continuously added into the support frame 30, and then a new ignition rod 32 is installed. Compare with traditional cable, this scheme utilization buffer layer 20 has still played good fire prevention effect when having guaranteed the high elasticity of cable.
