Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the enlarged diagram of fire extinguishing component of the invention.
Specific embodiment
As shown in Figure 1, this fire-resisting cable, including cable serving, cable serving include first shell 3 and second shell
Body 6, first shell 3 and second shell 6 form a circular cable serving structure；
There is an installation cavity inside cable serving, a cable core 7, the outer wall two sides of cable core 7 are installed in installation cavity
The air bag cushion 2 of one domes of each package, the centre of air bag cushion 2 have an air storing cavity 1, gas storage in air storing cavity 1, air bag cushion 2
Arc convex one end contacted with cable serving inner wall, the inner end of air bag cushion 2 is outside an arc-shaped concave, with cable core
Wall gluing is fixed, and first shell 3 and the open end of second shell 6 are assembled mutually, and open end is provided with a fire extinguishing component.
As shown in Fig. 2, fire extinguishing component includes the more than one shrinkage pool 4 being provided on 6 end face of second shell, each shrinkage pool
Extinguishing chemical is filled in 4, shrinkage pool 4 is open at one end with respect to first shell 3, and open end is sealed by first shell 3, and shrinkage pool 4 is built-in
Enter a sealing piston 5, sealing piston 5 is set to the lowermost end of shrinkage pool 4, an outboard end insertion piece pull of setting for sealing piston 5
Bar 8, the other end of pumping rod 8 are inserted in inside the first open end, and pumping rod 8 is the metal or plastic bar of a hard.
Due in its natural state when, shrinkage pool outboard end with first shell by being sealed, therefore internal extinguishing chemical sealing, works as cable core
When heat is very high, so that air bag cushion expands, and then the first, second shell is opened, so that sealing piston moves in shrinkage pool, in turn
The extinguishing chemical inside shrinkage pool is pulled out using sealing piston, the extinguishing chemical of pull-out can fall on cable core, effectively play fire-retardant
Effect.Since cable serving is opened, cable core is directly contacted with air, and then can increase radiating rate, reaches quick
Cooling.
In the present embodiment, an elastic component 9 is arranged with respect to shrinkage pool bottom surface side in the inner end of sealing piston, and elastic component 9 uses
A piece elastic webbing, elastic webbing one end are embedded in gluing in sealing piston and seal, and it is solid that the other end is embedded in gluing inside shrinkage pool bottom surface
Fixed, the effect of elastic webbing is elastic force can be utilized, so that the first, second shell reintegrates into one after ejection
Circular enclosed construction.
In the present embodiment, extinguishing chemical uses fire-fighting powder, and the main component of dry powder fire extinguishing agent is sodium bicarbonate and a small amount of
Anti-blushing agent magnesium stearate and talcum powder.The present invention uses a kind of common dry-chemical fire extinguishing of crime, when there is ignition point in cable core,
Temperature potential must be very high, and the dry powder being drawn out at this time can effectively realize fire extinguishing, or prevent fire source from spreading.
Wherein, the end face of second shell 6 is provided with a positioning convex portion 11, and it is recessed that the end face of first shell 3 is provided with a positioning
Portion, the positioning of positioning convex portion 11 are incorporated in location indentations.First shell 3 and second shell 6 are that mutual assembly positions, in temperature
Ining succession when very high can separate, therefore split type structure enables to the two to separate and is connected with outside air, realize quick
Cooling.
The beneficial effects of the present invention are: the one, present invention uses a kind of very simple structure, when cable temperature raising is too fast
When, air bag cushion expansion with the naked eye can be observed intuitively, if cable temperature is excessively high so that entire cable serving is opened；
Two, since cable serving is opened, internal cable core can be contacted directly with air, can be increased in this way
It is powered on the heat dissipation performance of cable core；
Three, it is spliced due to cable serving using the first, second shell, after cable heated opens, so that the
The fire-fighting powder of two enclosure interiors can be pulled out by sealing piston, and then the outside of cable core is covered on using dry powder, prevent cable
Core is lighted.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
