Abstract
The utility model relates to a miniature temperature measurement optical cable, including bare fiber, armor and weaving layer, laid a plurality of bare fibers in armoring layer, weaving layer parcel be in the skin of armor, wherein can increase the tight jacket layer of one deck and form tight jacket optic fibre outside every bare fiber. 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, in time, 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.
Description
Technical Field
The utility model belongs to optical cable processing field relates to the temperature measurement optical cable, especially a miniature temperature measurement optical cable.
Background
The optical fiber sensing technology is a new sensing technology accompanied with the development of optical fiber and optical fiber communication technology, which is the fastest high-tech application technology internationally developed since the middle of the 70 th century.
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 miniature temperature measurement optical cable, includes bare fiber, armor and weaving layer, has laid a plurality of bare fibers in armoring layer, the weaving layer parcel be in the skin of armor, wherein can increase the tight jacket layer of one deck outside every bare fiber and form tight jacket optic fibre.
The bare fiber can be a single mode fiber or a multimode fiber.
The armor layer is of 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.
The woven 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.
The woven layer may be provided as one or more layers.
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.
Drawings
Fig. 1 is a schematic cross-sectional view of the optical cable of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A miniature temperature measuring optical cable is shown in figure 1, the center of the miniature temperature measuring optical cable is provided with one to a plurality of bare optical fibers 4, if necessary, a tight-sleeve layer 3 can be added outside the bare optical fibers to form tight-sleeve optical fibers as primary protection for the optical fibers, and the type of the optical fibers can be single-mode optical fibers or multimode optical fibers.
The armor layer 2 is made of a metal tube, which can be made of various materials or processes, such as a stainless steel hose, a stainless steel welded tube, or a stainless steel welded corrugated tube, so as to improve the flexibility of the metal tube, or a copper welded tube or a copper corrugated tube.
The metal tube is externally woven with a certain thickness of galvanized thin steel wire or aluminum-clad thin steel wire or copper-clad thin steel wire or stainless steel wire to form a braided layer 1, so as to further improve the tensile capacity of the optical cable. If necessary, the braided layer can be added for many times to improve the tensile strength.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
