Background technology
Because most of collieries resource of China is in deep under ground, therefore in order to exploit these colliery resources, just need be on underground hundreds of rice reaches operation in the coal seam of km.Along with the development of automatic and mechanical infotech, except needs lay a large amount of power cables goes into the well along the coal mine shaft of the long distance of great depth, also need lay the communication line that is used for information transmission, comprise lightguide cable link.
Yet existing traditional optical cable has following technical matters:
Since the physical strength of optical fiber very a little less than, optical fiber is damaged easily.Therefore, conventional communications optical cable all adopts metal heavy armo(u)ring protection scheme.This scheme is to be cost to increase the optical cable deadweight, reaches the purpose of protection optical fiber.But when the coal mine shaft vertical run of the long distance of the great depth of km on the edge was used for the communications optical cable circuit of information transmission, heavy optical cable deadweight was except bringing to site operation the great difficulty, also owing to can reduce the serviceable life of deadweight effect optical cable.
Therefore, along with the development of coal mine machinery automated informationization technology, need a kind of mine vertical run optical cable of high strength light structure.
The utility model content
The technical matters that the utility model will solve provides a kind of mine vertical run optical cable, and it has high strength, from the characteristics of heavy and light, fire-retardant and electrostatic prevention.The communication and the sensing optic cable that lay apart from coal mine shaft with the great depth length that satisfy to go up km.Also be applicable to simultaneously the long distances of other great depths inflammable and explosive environment vertical vertical shaft communication and sensing optic cable lay application.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of mine vertical run optical cable, this optical cable comprise optical fiber, wrap up the first aramid fiber layer of this optical fiber, the flexible pipe of the optical cable inner sheath of the said first aramid fiber layer of parcel, the said optical cable inner sheath of parcel, be wrapped in the outer braiding webmaster of this corrugated hose, wrap up the second aramid fiber layer of this braiding webmaster and be wrapped in this second aramid fiber layer cable outer sheath outward.
Preferably, said flexible pipe is miniature corrugated hose.
Preferably, said braiding webmaster is a stainless steel wire braiding webmaster.
Preferably, said cable outer sheath adopts lightweight electrostatic prevention low-density flame retardant type pvc material.
The utility model is compared with the existing conventional optical cable, has high strength, from heavy and light, fire-retardant and electrostatic prevention characteristics.
The utility model patent is applicable to communication and the sensing optic cable that the great depth length of km is laid apart from coal mine shaft.Also be applicable to simultaneously the long distances of other great depths inflammable and explosive environment vertical vertical shaft communication and sensing optic cable lay application.Can alleviate the working strength and the technical difficulty of coal mine shaft laying optical cable greatly, significantly help improving the development degree of coal mine machinery automated informationization.
