The optical fiber is directly used as a sensor and needs to be based on a temperature measuring optical cable, the outermost layer of the existing temperature measuring optical cable technology is generally provided with a layer of non-metal sheath for protection, the heat conducting performance of general non-metal materials is poor, the rapid conduction of temperature is not facilitated, the timeliness of temperature conduction is delayed, the applicability is poor in the occasion where rapid temperature measurement is needed, and the rapid sensing of the temperature is not facilitated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide one kind and be applied to and need carry out the optical cable that temperature measurement used on continuous length, the optical cable structure is small and exquisite, and light in weight has better resistance lateral pressure and stretching resistance, is applicable to the very high occasion of resistance lateral pressure and stretching resistance.
The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides a strenghthened type temperature measurement optical cable, includes bare fiber, armor, weaving layer and protective sheath, has laid a plurality of bare fibers in armoring layer, the weaving layer parcel be in the skin of armor sets up one deck or multilayer protective sheath outside the weaving layer, wherein can increase the tight jacket layer of one deck outside every bare fiber and form tight-buffered optical fiber.
Moreover, the bare fiber may be a single mode fiber or a multimode fiber.
Moreover, the armor layer is a metal pipe structure, and the metal pipe can be one of a stainless steel hose, a stainless steel welded pipe, a stainless steel welded corrugated pipe, a copper welded pipe or a copper corrugated welded pipe.
And the braided layer is one of a galvanized thin steel wire, an aluminum-clad thin steel wire, a copper-clad thin steel wire or a stainless steel wire.
Furthermore, the woven layer may be provided as one or more layers.
And the protective outer sleeve is formed by twisting and armoring one of stainless steel wires, galvanized steel wires, aluminum-clad steel wires or copper-clad steel wires.
The utility model has the advantages that:
the utility model has the advantages of being scientific and reasonable in design, moreover, the steam generator is simple in structure, for improving prior art's defect, the sheath that no longer uses non-metallic material at outmost at the optical cable is as the protection, but use metallic material as protection and tensile member, there is not non-metallic material except optic fibre and protective layer in the whole optical cable material, and metallic material's temperature conductivity can be much better than non-metallic material's temperature conductivity, therefore the temperature conduction is quick, and is timely, can guarantee the quick reaction to temperature measurement, in time know the temperature distribution of whole circuit, better anti lateral pressure and stretching resistance have again simultaneously, the higher occasion of anti lateral pressure and stretching resistance requirement can be suitable for.
The utility model discloses use the thin steel wire of certain thickness's zinc-plated or the thin steel wire of aluminium package or the thin steel wire of copper clad or nonrust steel wire to weave the formation weaving layer in the outside of tubular metal resonator, with the tensile ability of further improvement optical cable, use one deck or multilayer rust steel wire or zinc-plated steel wire or aluminium package steel wire or copper clad steel wire to strand the armor in the outside of weaving layer, form the overcoat, in order to further improve the tensile ability and the anti side pressure ability of optical cable, produce and research and development a strenghthened type temperature measurement optical cable, be used for the occasion that requires high to optical cable tensile ability and anti side pressure ability.
