Background technique
Optical fiber cable for mine is coal mine flame-retardant communication cable or fire resistant optical communication cable for coal mine, due to the limit of underground particular surroundings
System needs optical cable to have good waterproof and rodent-proof characteristic, although at present mining is most of all to have waterproof and anti-rat,
But water-proof function is weak, still haves the defects that poor waterproof properties, and for protection against rodents, all there are many armours for most of optical cable
Layer is filled, but will increase the weight of optical cable, and present optical cable, when torsion, internal core can be due to internal pressure
And external lateral pressure damages, resistance to torsion capacity is poor.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of optical fiber cable for mine, which has protection against rodents and good anti-
Water function, and internal core is middle font, has good resistance to torsion capacity.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of optical fiber cable for mine, including core, and several cores are placed in nitrile rubber protective sleeve layer, nitrile rubber shield
Jacket layer is middle font, and several nitrile rubber protective sleeve layers constitute core body, and belting layer, nitrile rubber shield is arranged in the outside of online core
The cable cream that blocks water is filled between jacket layer and belting layer, is passed through polypropylene rope between adjacent nitrile rubber protective sleeve layer and is filled, core packet
Cable core is included, casing layer is set in the outside of cable core, waterproof layer is set in the outside of casing layer, painting is provided on the outside of waterproof layer
Inner restrictive coating is arranged in the outside of coat in coating, and PE restrictive coating, the outside setting of belting layer is arranged in the outside of inner restrictive coating
Metal net belt is provided with the external sheath layer of fluorescent powder on the outside of metal net belt.
A further improvement of the present invention is that: it is filled between core and nitrile rubber protective sleeve layer using several gum fillers,
The diameter of gum filler is-mm.
A further improvement of the present invention is that: waterproof layer is entwined by several layers of aramid fiber polyester yarn.
A further improvement of the present invention is that: coat includes base cloth layer, and upper and lower in base cloth layer is provided with water sucting belt
Layer, base cloth layer are polyester non-woven fabric base cloth layer, and water suction belt is bitumen layer.
A further improvement of the present invention is that: uniformly reinforcer is arranged in insertion in PE restrictive coating.
A further improvement of the present invention is that: belting layer is plastic-coated crawler belt belting layer.
The beneficial effects of the present invention are: the nitrile rubber protective sleeve layer on the outside of core of the present invention is middle font structure, have good
The ability of good resistance to torsion, and polypropylene rope connects between nitrile rubber protective sleeve layer, there is the ability of good rebound and recovery,
To the space of the good twisting of nitrile rubber protective sleeve, it is good that the waterproof layer and coat of the outside setting of cable core have optical cable
Good waterproof performance, and nitrile rubber protective sleeve inner utilization gum filler is filled, and anti-rat is compiled by one layer of metal
Knitmesh is realized, alleviates the weight of optical cable, and can also reach corresponding anti-rat.
The configuration of the present invention is simple, design are rationally novel, and easy to operate, cost of manufacture is cheap, can effectively realize optical cable
Waterproof, anti-rat, and make optical cable that there is good torsion and resilience.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram of coat of the present invention.
Specific embodiment
