Abstract
The invention discloses a novel mining-used temperature-sensitive cable comprising a fireproof insulation layer and thermistor wires. The fireproof insulation layer is internally provided with a metal braided shielding layer. The fireproof insulation layer is externally provided with an outer layer protective jacket. The fireproof insulation layer comprises a fire insulation layer which is made of a high-temperature-resistant elastomer plastic material. The high-temperature-resistant elastomer plastic material is in ceramic shape during burning. The fireproof insulation layer utilizes a composite material formed by rubber and polyvinyl chloride. The novel mining-used temperature-sensitive cable provided in the invention has the advantages of being long in service life, good in reliability, moistureproof and corrosionproof and the like, and the probability of fire hazard false alarm is effectively reduced.
Description
Technical field
The present invention relates to a kind of mining cable, relate in particular to a kind of new type mining temperature sensing cable.
Background technology
In field of communication transmission, cable is a kind of very important transmission medium, is widely used in signal transmission technology field.At present, a lot of places are as located fire-fighting requirement very strict in colliery, oil field etc., need fire alarm detecting devices very reliably, conventional temperature sensing fire alarm, general using temperature sensing cable as the existing temperature sensing cable in source of signals collecting by two or two strands of wires, be coated one deck temperature-sensitive insulating material thereon, overlapping last layer oversheath forms again, exist the easy erosions such as oversheath seal is poor, steam, corrosive gas to enter, make on wire megohmite insulant easily aging, useful life is short, and the shortcomings such as false alarm, poor reliability easily occur.
Summary of the invention
Technical problem to be solved by this invention is: a kind of good seal performance is provided, responds to new type mining temperature sensing cable sensitive, long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A new type mining temperature sensing cable, comprises refractory insulating layer, thermal resistor wire, is provided with metal knitted screen in described refractory insulating layer, and described refractory insulating layer is provided with outer layer protective sleeve outward; Described refractory insulating layer comprises the refuge floor that adopts high temperature resistant elastomer plastic material, and described high temperature resistant elastomer plastic material will be the high temperature resistant elastomer plastic material of ceramic-like while being burning; The composite material that described refractory insulating layer adopts rubber and polyvinyl chloride to form.
Described metal knitted screen is the metallic shield net of being made by metal wire knitted.
Described metal knitted screen is wrapped in the outside of thermal resistor wire, and signal hop is by mutual stranded the forming of 4 wires, and the filler that blocks water of need annotating in its gap.
Described outer layer protective sleeve is the nylon layer of being made by nylon yarn braiding.
Compared with prior art, the beneficial effect that the present invention has is:
A kind of new type mining temperature sensing cable of the present invention has the advantages such as long service life, good reliability, protection against the tide, anticorrosion, has effectively reduced the probability of fire wrong report.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of new type mining temperature sensing cable of the present invention.
In figure, be labeled as: thermal resistor wire 1, the filler 2 that blocks water, metal knitted screen 3, refractory insulating layer 4, outer layer protective sleeve 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Refer to Fig. 1, a kind of new type mining temperature sensing cable, comprises refractory insulating layer 4, thermal resistor wire 1, is provided with metal knitted screen 3 in described refractory insulating layer 4, the outer outer layer protective sleeve 5 that is provided with of described refractory insulating layer 4; Described refractory insulating layer 4 comprises the refuge floor that adopts high temperature resistant elastomer plastic material, and described high temperature resistant elastomer plastic material will be the high temperature resistant elastomer plastic material of ceramic-like while being burning; The composite material that described refractory insulating layer 4 adopts rubber and polyvinyl chloride to form.Described metal knitted screen 3 is metallic shield nets of being made by metal wire knitted; Described metal knitted screen 3 is wrapped in the outside of thermal resistor wire 1, and signal hop is by mutual stranded the forming of 4 wires, and the filler 2 that blocks water of need annotating in its gap; Described outer layer protective sleeve 5 is nylon layers of being made by nylon yarn braiding.
The present invention can select thermo-sensitive material as required, and when reaching melt temperature, thermo-sensitive material can melt, the elastic metallic yarn of parcel contacts thermal resistor wire, resistance value changes, and decoding signals can this variation of perception, when reaching predefined temperature parameter, reports to the police.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
