Description
Technical field
The utility model relates to optical cable, the Novel optical cable of particularly a kind of mine safety transmission.
Background technology
The space situations of the relative closure such as railway tunnel, subway, track traffic, skyscraper, oil depot, mine, more and more wider application optical fiber cable do to transmit optical fiber communication, monitoring and controlling system, particularly firefighting monitoring system, the optical cable adopted after fire occurs can very fast burn injury, cause the thrashing that optical fiber cable transmits, for this reason, flame-proof cable starts to be applied to this type systematic.Optical cable is in the market Traditional center tubular type optical fibre band optical cable, sheath half is made up of plastics or other waterproof, fire prevention, smokeless material, such optical cable bore is little, be adapted at applying in Metropolitan Area Network (MAN) and Access Network, but fire performance does not reach the standard about buildings prescribed material, when running into fire, cannot satisfy the demand.
Chinese Patent Application No.: 201220256392.4 disclose a kind of flame-retardant Polyvinylchloride fluorescence cable, it is characterized in that: its outermost layer adopts fluorescent polyvinyl chloride layer, flame-proof polyvinyl chloride oversheath is provided with in fluorescent polyvinyl chloride layer, glass fibre lapping layer is provided with in flame-proof polyvinyl chloride oversheath, at least one group of flame-proof polyvinyl chloride insulation course is provided with in glass fibre lapping layer, be provided with quartz fibre band lapping layer in flame-proof polyvinyl chloride insulation course, in quartz fibre band lapping layer, be provided with conductor.This cable can stop when breaking out of fire or hinders the burning of flame and within the scope of conductor melting point, ensure cable continuous firing and can continue to send fluorescence in the place of night or dark.This utility model has done technological improvement at cable at protective sleeve, but it only has one deck fire retardant matter as fire-proof function, and fire retardant matter is destroyed, and cable or optical cable will directly be destroyed.
Chinese Patent Application No.: 201120451666.0 disclose a kind of metalloid core pipe Full-dry optical cable, comprise cable core and sheath, non-metal reinforcement member is surrounded with outside cable core, oversheath has been extruded outside non-metal reinforcement member, non-metal reinforcing band is by complex root fiber and gluingly form a vertical bag shoestring, the xsect of vertical bag shoestring is rectangular, coating hot-melt adhesive coating on the surface of the side of vertical bag shoestring.Such structure fire resistance and fire performance cannot meet requirement when unexpected situation occurs.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the Novel optical cable of the mine safety transmission that a kind of fire performance is strong, intensity is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel optical cable of mine safety transmission, it comprises oversheath, inner sheath and composite band, inner sheath is arranged in oversheath, composite band is arranged in inner sheath, several Loose tube and reinforcement are installed in composite band, described reinforcement is made up of glass fiber reinforced plastics, composite band, the cable cream that blocks water is filled with in gap between Loose tube and reinforcement, some optical fiber are installed in Loose tube, gap-fill between Loose tube and optical fiber has fine cream, described oversheath and Loose tube are made by fire proofing.
Some described optical fiber are that SZ type is stranded.
Described composite band is composite steel-plastic belt.
Several described Loose tube are evenly distributed on around reinforcement.
The utility model has the following advantages:
1. the oversheath of this optical cable and Loose tube make by using fire proofing, multi-layer fire-retarded protection can be realized, this optical cable is made to be subject to damage or after being subject to fire damage, Loose tube still can protect optical fiber to be subject to influence of fire and to cause Signal transmissions to interrupt when oversheath;
2. this optical cable can prevent optical cable owing to making moist in Minepit environment thus causing serviceable life of the aging raising optical cable such as Loose tube and reinforcement by filling the cable cream that blocks water;
3. this optical cable is by using the reinforcement made of glass fiber reinforced plastics, the intensity of this optical cable can be increased, improve its tension, anti-pressure ability, and due to glass fiber reinforced plastics quality light, optical cable can not be allowed obviously to increase weight, facilitate the transport of optical cable and lay;
4. by making optical fiber be that SZ type is stranded, the strength of joint of optical fiber can be improved, and can effectively prevent optical fiber loose, facilitate optical fiber to load in Loose tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Novel optical cable of a kind of mine safety transmission.
In figure, 1-oversheath, 2-inner sheath, 3-composite band, 4-blocks water cable cream, 5-reinforcement, 6-Loose tube, the fine cream of 7-, 8-optical fiber.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of Novel optical cable of mine safety transmission, it comprises oversheath 1, inner sheath 2 and composite band 3, inner sheath 2 is arranged in oversheath 1, composite band 3 is arranged in inner sheath 2, in the present embodiment, described composite band 3 is composite steel-plastic belt, several Loose tube 6 and reinforcement 5 are installed in composite band 3, in the present embodiment, several described Loose tube 6 are evenly distributed on around reinforcement 5, described reinforcement 5 is made up of glass fiber reinforced plastics, because glass fiber reinforced plastics has lightweight, specific strength is high, corrosion-resistant, electrical insulation capability is good, heat transfer is slow, thermal insulation is good, resistance to instantaneous superhigh temperature performance is good, easily painted and can through characteristics such as electromagnetic waves, using glass fiber reinforced plastics to be used as reinforcement can not allow optical cable obviously increase weight, facilitate the transport of optical cable and lay, and the tension of optical cable can be improved, compressive strength, optical cable is made not to be vulnerable to physical damage, composite band 3, the cable cream 4 that blocks water is filled with in gap between Loose tube 6 and reinforcement 5, some optical fiber 8 are installed in Loose tube 6, in the present embodiment, described some optical fiber 8 are stranded in SZ type, gap-fill between Loose tube 6 and optical fiber 8 has fine cream 7, described oversheath 1 and Loose tube 6 are made by fire proofing, with this, Double-layer flame-retardant layer is set, strengthen the anti-flaming function of optical cable.
