Further, the adhesive is a resin or a cured adhesive material.
The utility model has the advantages that: the utility model discloses a high sensitive sensing optical fiber unit optic fibre can external vibration, pulling force, lateral pressure of sensitive perception, temperature variation etc. And the production process is simple, the production schedule is fast, and the method has great economic benefit and social benefit.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the optical fiber module comprises a reinforced core, 2, an optical fiber, 3, an adhesive, 4, a water-blocking composite material and 5, a stainless steel sleeve.
Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1, a high-sensitivity sensing optical fiber unit comprises a reinforced core 1, optical fibers 2 and a stainless steel sleeve 5, wherein the reinforced core 1 is externally twisted with a plurality of optical fibers 2, the optical fibers 2 are fixed by an adhesive 3, and the optical fibers 2 are sequentially coated with a water-blocking composite material 4 and the stainless steel sleeve 5. Wherein, the reinforced core 1 is a copper wire, a steel wire or a round bar made of non-metal materials. The water-blocking composite material 4 is a post-cured water-blocking composite material. The adhesive 3 is a resin or a cured adhesive material.
A method for manufacturing a high-sensitivity sensing optical fiber unit comprises the following steps:
a. And (3) optical fiber treatment: coloring or extruding a tight cladding on the bare optical fiber 2 according to requirements, and distinguishing the optical fibers 2 by colors;
b. Optical fiber stranding: stranding a plurality of optical fibers 2 at the periphery of the reinforced core 1, and coating an adhesive 3 to fix the optical fibers 2 and the reinforced core 1 while stranding to form an optical fiber bundle;
c. Manufacturing a stainless steel sleeve: the stainless steel band is formed into a round tube by a mould, and a middle gap is welded into a stainless steel sleeve 5 by laser welding or argon arc welding;
d. Filling: and actively paying off the optical fiber 2 bundle, wherein the tension can be accurately controlled so as to keep the tension of the optical fiber bundle constant, filling the post-cured water-blocking composite material 4 and the optical fiber 2 bundle into the stainless steel sleeve 5 through a filling nozzle of an injection pump, standing for a period of time, curing the water-blocking composite material 4 in the stainless steel sleeve 5, and completing production.
In step d, the filling nozzle of the injection pump is required to go over the welding point of the stainless steel sleeve 5 during filling. The optical fiber 2 and the post-cured water-blocking composite material 4 can be protected from the high temperature of the welding point, and the necessary post-cured water-blocking composite material 4 can be injected into the stainless steel sleeve 5 at a high filling rate.
The setting of reinforcer makes the elasticity of optic fibre better, and the reinforcer is copper line, copper wire or non-metallic material pole, and intensity is high, tensile strength is strong, helps improving the intensity, the tensile strength of the optic fibre of the outer transposition of reinforcer. The optical fiber is bonded and fixed into a whole by the adhesive, the reinforced core and the water-blocking composite material, is not easily interfered by the external environment, and can sensitively sense the external vibration, the pulling force, the lateral pressure, the temperature change and the like. The water-blocking composite material outside the optical fiber is a post-cured water-blocking composite material, so that the filling rate of the optical fiber when the optical fiber is filled into the stainless steel sleeve can be ensured, and the surface of the optical fiber can be isolated from the outside, so that the mechanical fatigue loss of the optical fiber and the loss increase of hydrogen molecules are improved. The stainless steel sleeve on the outermost layer improves the tensile property and the wear resistance of the optical fiber, prolongs the service life of the optical fiber,
The utility model discloses an all components bond into a whole among the high sensitive sensing optical fiber unit, are difficult for receiving external environment's interference, and can the external vibration of sensitive perception, pulling force, lateral pressure, temperature variation etc.. The sensor cable can be used as a separate sensing cable and can also be used in an optical cable needing sensing. And the production process is simple, the production schedule is fast, and the method has great economic benefit and social benefit.
