Abstract
The utility model aims to provide a coal mine water-proof flame-retardant braided shielding control cable which is efficiently suitable for water environment with high humidity in a coal mine, and can not be damaged when generating gas explosion. The coal mine water-proof flame-retardant braided shielding control cable is characterized in that 1, a power cable is formed by twisting at least two single core cable, 2, each single core cable is sequentially formed by a conductor and an insulating layer from inside to outside, and 3, a water blocking packing layer, an inner sheath, a water blocking belt, a woven shielding layer and an outer sheath are sequentially arranged outside the twisted cable from inside to outside. Eighty theoretically possible schemes are selected, and after hundreds of experiments, the experiment effects of the theoretically possible schemes are not ideal except that of the scheme of the pattern claim VI which includes wearing out the outer sheath and damaging the shielding layer, after steeping 30 days in coal water with the temperature of 50 DEG C and then performing gas explosion experiment, the cable still can be controlled with the best effect, can be effectively suitable for water environment with high humidity in a coal mine, and can not be damaged when generating gas explosion.
Description
Technical field
The utility model belongs to the control cable field, specifically is exactly colliery water proof fire retardant braid shielded control cable.
Background technology
The exploitation fast development of mineral resources such as coal, underground work deepens continuously, increase day by day in inflammable and explosive complex environment and the abominable place of waiting, cause mining electric automatization equipment degree to improve constantly, security system function is continually strengthened, and the popularization and the utilization that particularly have the Automatic monitoring systems equipment of high-tech content get more and more.Common mining signal cable more and more can not satisfy the requirement of high rate data transmission signal under worse colliery environment.
Environment in the coal mine, be a kind of special adverse circumstances, substantially be under water environment, and high humidity, if taking place, gas explosion damages cable, will be because of the cable bad expansion that causes damage, and present control cable is various, the material of the outer coated winding of conductor and the mode that these materials are arranged from the inside to surface successively are multifarious, but the control cable that effectively is fit to adverse circumstances in the coal mine does not also have.
Summary of the invention
The purpose of this utility model is to provide the water environment that effectively is fit in the coal mine, and high humidity is if the colliery water proof fire retardant braid shielded control cable that gas explosion does not damage takes place.
The utility model is achieved in that colliery water proof fire retardant braid shielded control cable, it is characterized in that:
1. described power cable is by at least two stranded forming of single-core cable;
2. every single-core cable is made of conductor, insulating barrier from the inside to surface successively
3. the twisted cable outside is made of the packed layer that blocks water, inner sheath, waterstop, woven shield and external sheath layer from the inside to surface successively.
Described colliery water proof fire retardant braid shielded control cable is characterized in that: described twisted cable is four stranded forming of single-core cable.
Described colliery water proof fire retardant braid shielded control cable, it is characterized in that: described conductor is a copper free wire.
Described colliery water proof fire retardant braid shielded control cable, it is characterized in that: the described packed layer that blocks water is a waterproofing rope.
Described colliery water proof fire retardant braid shielded control cable, it is characterized in that: described inner sheath and external sheath layer are high flame retardant polyvinyl chlorides.
Described colliery water proof fire retardant braid shielded control cable is characterized in that: described woven shield is a count greater than 80% copper free wire.
The material of the outer coated winding of conductor and the mode that these materials are arranged from the inside to surface successively, reach thousands of kinds through permutation and combination, feasible more than 80 kind of scheme on the Choice Theory, find through 100 test of many times, the test effect of the most feasible several schemes is unsatisfactory in theory, the scheme of having only claim 6, worn out and the damage screen with the oversheath many places, soaked in 50 ℃ of coal water 30 days, then carry out the gas explosion test after, this cable still can be implemented control, effect is best, can effectively be fit to the water environment in the coal mine, the requirement that gas explosion does not damage takes place in high humidity.
