Description
Technical field
The present invention relates to optical cable technology field more particularly to a kind of highly sensitive sensor fibre unit and its manufacturing methods.
Background technique
Optical fiber in the prior art is mostly used as transmission medium to use, if using as sensing, optical fiber needs sensitiveer
Perceive extraneous vibration, pulling force, lateral pressure, temperature change etc..Optical fiber is as transmission medium in use, optical fiber is required to be not susceptible to
The interference of external environment, so highly sensitive sensing light unit requires to be different with the fiber unit in traditional optical cable.
Summary of the invention
For vibration, pulling force, lateral pressure, the temperature change etc. for keeping the sensitive perception of optical cable extraneous, the purpose of the present invention is be
A kind of highly sensitive sensor fibre unit is provided.
Correspondingly, another object of the present invention is to be to provide a kind of manufacturer of highly sensitive sensor fibre unit
Method.
To achieve the above object, the invention is realized by the following technical scheme: a kind of highly sensitive sensor fibre unit, including
Strengthening core, optical fiber, stainless steel sleeve pipe, the strengthening core is twisted outside multifiber, and the optical fiber is fixed by adhesive, described
The composite material that blocks water, stainless steel sleeve pipe are successively coated with outside optical fiber.
Further, the strengthening core is copper wire, steel wire or nonmetallic materials pole.
Further, the composite material that blocks water is the rear cured composite material that blocks water.
Further, the adhesive is resin or curing binder material.
A kind of manufacturing method of highly sensitive sensor fibre unit, comprising the following steps:
A. optical fiber processing: bare fibre is coloured or is extruded according to demand hard-pressed bale layer, distinguished between optical fiber using color；
B. optical fiber is twisted: multifiber being stranded in strengthening core periphery, adhesive coating makes optical fiber and strengthening core while twisted
It is fixed, form fiber optic bundle；
C. make stainless steel sleeve pipe: stainless steel band is molded to form round tube, and intermediate gap is welded using Laser Welding or argon
Arc welding is at stainless steel sleeve pipe；
D. fill: rear cured block water composite material and fiber optic bundle are packed into stainless steel sleeve pipe by the applying nozzle of injection pump
In, after placing a period of time, the composite material that blocks water inside stainless steel sleeve pipe solidifies, and production is completed.
Further, in the step d, the applying nozzle of injection pump will cross the welding of stainless steel sleeve pipe in filling
Point.
Beneficial effects of the present invention: highly sensitive sensor fibre unit optical fiber of the invention being capable of the extraneous vibration of sensitive perception
Dynamic, pulling force, lateral pressure, temperature change etc..And simple production process, manufacturing schedule is fast, has biggish economic benefit and society
It can benefit.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein: 1, strengthening core, 2, optical fiber, 3, adhesive, 4, block water composite material, 5, stainless steel sleeve pipe.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
As shown in Figure 1, a kind of highly sensitive sensor fibre unit, including strengthening core 1, optical fiber 2, stainless steel sleeve pipe 5, strengthening core
Twisted outside 1 to have multifiber 2, optical fiber 2 is fixed by adhesive 3, and block water composite material 4, stainless steel are successively coated with outside optical fiber 2
Casing 5.Wherein, strengthening core 1 is copper wire, steel wire or nonmetallic materials pole.The composite material 4 that blocks water be it is rear it is cured block water it is compound
Material.Adhesive 3 is resin or curing binder material.
A kind of manufacturing method of highly sensitive sensor fibre unit, comprising the following steps:
A. optical fiber processing: bare fibre 2 is coloured or extruded hard-pressed bale layer according to demand, is distinguished between optical fiber 2 using color；
B. optical fiber is twisted: multifiber 2 being stranded in 1 periphery of strengthening core, adhesive coating 3 makes optical fiber 2 and adds while twisted
Strong core 1 is fixed, forms fiber optic bundle；
C. make stainless steel sleeve pipe: stainless steel band is molded to form round tube, and intermediate gap is welded using Laser Welding or argon
Arc welding is at stainless steel sleeve pipe 5；
D. fill: 2 beam of optical fiber uses active unwrapping wire, and tension accurately controls to keep fiber optic bundle constant tension, rear cured
It blocks water composite material 4 and 2 beam of optical fiber is packed into stainless steel sleeve pipe 5 by the applying nozzle of injection pump, after placing a period of time,
The solidification of composite material 4 that blocks water inside stainless steel sleeve pipe 5, production are completed.
Wherein, in step d, the applying nozzle of injection pump will cross the pad of stainless steel sleeve pipe 5 in filling.It can
Optical fiber 2 and the rear cured composite material 4 that blocks water is protected not to be influenced by pad high temperature, and can will be necessary with the very high rate that is filled with
It is rear it is cured block water composite material 4 inject stainless steel sleeve pipe 5 in.
So that the elasticity of optical fiber is more preferable, strengthening core is copper wire, steel wire or nonmetallic materials pole, intensity for the setting of strengthening core
Height, tensile property are strong, help to improve intensity, the pull resistance of optical fiber twisted outside strengthening core.Optical fiber passes through adhesive and reinforcement
An entirety is adhesively fixed into core, the composite material that blocks water, not vulnerable to the interference of external environment, and can the extraneous vibration of sensitive perception
Dynamic, pulling force, lateral pressure, temperature change etc..The composite material that blocks water outside optical fiber is the rear cured composite material that blocks water, and can guarantee light
It is filled with rate when fibre is packed into stainless steel sleeve pipe, and optical fiber surface can be made to be isolated from the outside, to improve the mechanical fatigue of optical fiber
Loss and the loss of hydrogen molecule increase.Outermost stainless steel sleeve pipe improves the pull resistance and wearability of optical fiber, extends light
Fine service life,
All member bonds are at an entirety in highly sensitive sensor fibre unit of the invention, not vulnerable to the interference of external environment,
And it can sensitive perception extraneous vibration, pulling force, lateral pressure, temperature change etc..It can be used as individual sensing cable to use, it is also possible to
In the optical cable for needing to sense.And simple production process, manufacturing schedule is fast, has biggish economic benefit and social benefit.
