Abstract

The invention discloses a signal transmission line for gobs of coal mines. The signal transmission line comprises a conductor and a shielding layer; an insulating layer made of polyester resin materials covers the outside of the conductor; the shielding layer comprises an inner layer and an outer layer, the inner layer is a tin foil layer, and the outer layer is a metal braided layer; the tin foil layer covers the outside of the insulating layer; flame-retardant rubber covers the outside of the metal braided layer which is the outer layer of the shielding layer; an asbestos layer and an indium steel wire sequentially cover the outside of the flame-retardant rubber from the inside to the outside; the diameter of the indium steel wire ranges from 0.8mm to 1.2mm. The signal transmission line has the advantages that the signal transmission line is high-temperature-resistant; signal loss can be reduced owing to the shielding layer, and the signal transmission reliability of the signal transmission line is improved; the flame-retardant rubber and the asbestos layer can realize heat-insulation and flame-retardant effects, and accordingly heat-resistant and anti-explosion properties of the signal transmission line are improved; the signal transmission line is sufficiently strong and is tough to a certain degree owing to the indium steel wire wound on the outermost layer of the signal transmission line, the signal transmission line is not easy to rust in high-temperature and humid environments, accordingly, the environmental adaptability of the signal transmission line is improved, and the service life of the signal transmission line is prolonged.

Description

The signal transmssion line that uses in a kind of coal mine gob
Technical field
The present invention relates to a kind of transmission line, the signal transmssion line that uses in especially a kind of coal mine gob.
Background technology
Behind the seam mining, the working face rear forms the goaf, As time goes on, can there be potential safety hazard in the goaf, gathers such as pernicious gases such as gas, the spontaneous combustion of coal seam that goaf high temperature causes, or even gas explosion etc., thereby in the goaf relevant watch-dog must be arranged.The signal transmssion line of these equipment is in the goaf in the adverse circumstances such as humidity, high temperature always, avoids damaging in order to protect transmission line, guarantees the reliability of transmission line, needs take effective safeguard measure to transmission line.
Traditional guard method to transmission line generally is that transmission line is placed steel pipe, although this method can make transmission line injury-free, and can not be crooked.Under coal mine; the various device that many other purposes are also arranged near the tunnel working face and the goaf; the magnetic field that these equipment produce, radio frequency, static etc. can produce device signal transmission in the goaf and disturb; cause effectiveness low, poor reliability, thereby existing signal transmssion line does not have the function of autoprotection; but place steel pipe; owing to being subjected to the impact of magnetic field, radio frequency, static etc., causing effectiveness low, poor reliability.
Summary of the invention
In order to protect the transmission line in the goaf to avoid damaging, guarantee that the reliability of signal transmission the invention provides the signal transmssion line that uses in a kind of coal mine gob.
The technical solution adopted in the present invention is: the signal transmssion line that uses in a kind of coal mine gob, comprise wire, screen, and the outside of wire is coated on the insulating barrier of polyester resin material;
Screen two-layerly is made of inside and outside, and internal layer is the tinfoil paper layer, outerly is wire sheathing; The tinfoil paper layer is coated on the outside of insulating barrier;
The outside of the outer field wire sheathing of screen is coated with fire-retardant rubber; The outside of fire-retardant rubber is coated with asbestos layer and indium steel wire from inside to outside successively; The indium gauge of wire is 0.8mm～1.2mm.
Beneficial effect of the present invention:
The present invention is coated on the insulating barrier of wire outside, can be high temperature resistant; Screen can reduce the loss of signal, improves the reliability of signal transmission of the present invention; Fire-retardant rubber and asbestos layer can play the effect of heat-insulating flame-retardant, improve heat-resisting and explosion-proof performance of the present invention; Be wound in outermost indium steel wire and make the existing enough intensity of the present invention, certain toughness is arranged again, and in the high temperature wet environment, be difficult for getting rusty, improved adaptive capacity to environment of the present invention and useful life.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is generalized section of the present invention.
Among the figure: 1, wire; 2, insulating barrier; 3, screen; 4, fire-retardant rubber; 5, asbestos layer; 6, indium steel wire; 31, tinfoil paper layer; 32, wire sheathing.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the present invention includes wire 1, insulating barrier 2, screen 3, fire-retardant rubber 4, asbestos layer 5, indium steel wire 6.Wire 1 is used for signal transmission.
Insulating barrier 2 is coated on the outside of wire 1, and its material is polyester resin, can be high temperature resistant, have good fire resistance, the infringement of avoiding to greatest extent high temperature that wire is caused.
Screen 3 two-layerly is made of inside and outside, and internal layer is tinfoil paper layer 31, outerly is wire sheathing 32.Tinfoil paper layer 31 is coated on the outside of insulating barrier 2, can resist preferably electromagnetic interference, reduces the loss in the signals transmission.Wire sheathing 32 can be resisted electromagnetic interference to large extent.Tinfoil paper layer 31 in the screen 3 forms dual shield with wire sheathing 32, thereby effectively reduces the interference such as magnetic field, static, has improved the stability of signal transmission.
Fire-retardant rubber 4 is coated on the outside of screen 3 outer field wire sheathings 32, and its material is mining flame-retardant rubber, has good fire resistance, and the control transmission line is because of high-temp combustion.
Asbestos layer 5 is coated on fire-retardant rubber 4 outsides, its material is asbestos, in order to improve tensile strength of the present invention, chemically-resistant and thermal etching, prolonged the life-span of the present invention in the adverse circumstances of goaf, provide relatively stable, safe operational environment for inner various piece to greatest extent.
Indium steel wire 6 is wound in the outside of asbestos layer 5, and its diameter is 0.8mm～1.2mm.Indium steel wire 6 makes the existing enough intensity of the present invention, certain toughness is arranged again, and be difficult for getting rusty in the high temperature wet environment, makes to greatest extent inner various piece avoid wearing and tearing, for the invention provides physical protection.
In sum, a kind of transmission line for the goaf provided by the invention is compared with transmission line in the past, and this use is novel to have the following advantages:
By above-mentioned technical characterictic, insulating barrier 2, fire-retardant rubber 4, asbestos layer 5 can be heat insulation, fire-retardant, high temperature resistant; Screen 3 can reduce the loss of signal, improves the reliability of signal transmission of the present invention; Indium steel wire 6 makes the existing enough intensity of the present invention, certain toughness is arranged again, and be difficult for getting rusty in the high temperature wet environment, for the invention provides physical protection, has improved adaptive capacity to environment of the present invention and useful life.
The above, it only is preferred embodiment of the present invention, be not the restriction to the technology of the present invention scope, therefore simple modification, equivalent variations and modification that all foundations technical spirit of the present invention is done above-described embodiment all still belong in the novel technical scope of this use.
