Background technology
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 is, it is necessary to which optical cable has good waterproof and rodent-proof characteristic, although it is current it is mining it is most of all there is waterproof and anti-rat,
But water-proof function is weak, the defect that still there are poor waterproof properties, and for protection against rodents, most optical cable has a variety of armours
Layer is filled, but the weight of optical cable can be increased, and present optical cable, when reversing, internal core can be due to internal pressure
And outside lateral pressure causes to damage, resistance to torsion capacity is poor.
The content of the invention
In order to solve the above problems, the invention provides a kind of optical fiber cable for mine, the optical cable has protection against rodents and good anti-
Water function, and internal core is middle font, with 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 body, and several core bodys are placed in nitrile rubber protective sleeve layer, nitrile rubber protective sleeve layer
For middle font, several nitrile rubber protective sleeve layers constitute core body, and the outside of online core body sets belting layer, nitrile rubber protective sleeve layer
Fill and filled between the cable cream that blocks water, adjacent nitrile rubber protective sleeve layer by polypropylene rope between belting layer, core body includes cable
Core, casing layer is set in the outside of cable core, sets waterproof layer in the outside of casing layer, coating is provided with the outside of waterproof layer
Layer, inner restrictive coating is set in the outside of coat, and PE restrictive coatings are set in the outside of inner restrictive coating, and the outside of belting layer sets gold
Belong to the external sheath layer that fluorescent material is provided with the outside of mesh grid belt, metal net belt.
Further improvement of the present invention is：Using the filling of several gum fillers between core body and nitrile rubber protective sleeve layer,
A diameter of-mm of gum filler.
Further improvement of the present invention is：Waterproof layer is entwined by several layers of aramid fiber polyester yarn.
Further improvement of the present invention is：Coat includes base cloth layer, and water sucting belt is provided with up and down in base cloth layer
Layer, base cloth layer is polyester non-woven fabric base cloth layer, and water suction belt is bitumen layer.
Further improvement of the present invention is：Uniform insertion sets reinforcer in PE restrictive coatings.
Further improvement of the present invention is：Belting layer is plastic-coated crawler belt belting layer.
The beneficial effects of the invention are as follows：Nitrile rubber protective sleeve layer on the outside of core body of the present invention is middle font structure, with good
Polypropylene rope is connected between the ability of good resistance to torsion, and nitrile rubber protective sleeve layer, there is good resilience and the ability recovered,
To the space of the twisting of nitrile rubber protective sleeve well, the waterproof layer and coat of the outside setting of cable core all cause optical cable has good
Good water resistance, and the filling of nitrile rubber protective sleeve inner utilization gum filler, anti-rat is compiled by layer of metal
Knitmesh is realized, alleviates the weight of optical cable, and can also reach corresponding anti-rat.
Present invention novelty simple in construction, reasonable in design, easy to operate, cost of manufacture is cheap, can effectively realize optical cable
Waterproof, anti-rat, and cause optical cable that there is good torsion and resilience.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of coat of the present invention.
