Abstract
The utility model discloses a non-metal strain sensing optical cable, which comprises a cable core, wherein the cable core is composed of an optical unit and strengthening cores, a plurality of strengthening cores are tightly stranded at the periphery of the optical unit, the periphery of the strengthening core is coated by a copolymer, the optical unit is composed of an optical fiber and the copolymer coated at the periphery of the optical fiber, and the periphery of the cable core is coated by a sheath. The non-metal strain sensing optical cable has the advantages that a force condition or the extent of damage of an object, for example, a dam, a bridge and the like, is detected through the optical cable, the work efficiency is high, thereby conforming to requirements in the prior art.
Description
Technical field
The utility model relates to straining sensing optical cable, relates in particular to a kind of nonmetal straining sensing optical cable.
Background technology
For for straining sensing optical cable, the basic design principles of its structure be allow outside some or certain is several sensitive and pass in real time the optical fiber in cable by heat transfer agent.Therefore, strain sensing cable mainly adopts locking structure technology, conventionally adopts tightly packaged fiber and in cable, do not have Yu Changhuo to have a certain amount of negative remaining long.This cable is placed in the object that will monitor, in the time that cable is subject to external force with object, there is a strain in cable, due to optical fiber and cable be one fit closely, so optical fiber also produces strain, strain information is passed to outer monitoring equipment by optical fiber, by the stressed size of big or small perceptual object or the extent of damage of strain.When straining sensing optical cable of the prior art uses, sensitivity is not high, and work efficiency is low, does not meet demand of the prior art.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
Utility model content
The utility model provides a kind of nonmetal straining sensing optical cable.
The technical solution adopted in the utility model is:
A kind of nonmetal straining sensing optical cable, comprise cable core, described cable core is made up of light unit and strengthening core, the peripheral closely stranded some strengthening cores in described smooth unit, described strengthening core periphery is coated with multipolymer, described smooth unit is made up of optical fiber and the multipolymer that is coated on optical fiber periphery, and described cable core periphery is coated with sheath.
Described strengthening core is aramid fiber reinforcing optical cable reinforced core.
Described multipolymer is ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer.
Described sheath material is tygon.
The utility model has the advantages that: detect object receiving force situation or the extent of damage by this optical cable, such as dam, pontic etc., work efficiency is high, meets demand of the prior art.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, strengthening core, 2, multipolymer, 3, optical fiber, 4, sheath.
Embodiment
As shown in Figure 1, the nonmetal straining sensing optical cable of one of the present utility model, comprise cable core, described cable core is made up of light unit and strengthening core 1, the peripheral closely stranded some strengthening cores 1 in described smooth unit, described strengthening core 1 periphery is coated with multipolymer 2, described smooth unit is made up of optical fiber 3 and the multipolymer 2 that is coated on optical fiber 3 peripheries, described cable core periphery is coated with sheath 4, described strengthening core 1 is aramid fiber reinforcing optical cable reinforced core, described multipolymer 2 is ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer, described sheath 4 materials are tygon, detect object receiving force situation or the extent of damage by this optical cable, such as dam, pontic etc., work efficiency is high, meet demand of the prior art.
Adopt squash type at optical fiber 3 outer cladding multipolymers 2 by optical fiber hard-pressed bale extrusion equipment, and ensure that optical fiber 3 overlays are combined closely with multipolymer 2 adhesions, the outer employing squash type of strengthening core 1 extrusion way is coated last layer copolymerization 2, then by the S cage winch that can accurately control tension force, strengthening core 1 is closely stranded in to light unit with specific pitch and forms cable core around, because making stranded rear smooth unit, the control of tension force obtains more than zero long or quantitative negative remaining length, last cable core is through the coated one deck oversheath 4 of extruding machine, by the control of temperature and the speed of a motor vehicle and the temperature of coated sheath 4, cable core is heated, make the multipolymer adhesion outside each element, multipolymer and oversheath adhesion are tight, optical cable becomes a tight association, each interelement does not produce slippage.In the time that optical cable is subject to external force, optical fiber is along with strain together, and optical fiber passes to strain information the system of tracking, can reach monitoring object receiving force or impaired state.
Claims (4)
1. a nonmetal straining sensing optical cable, comprise cable core, it is characterized in that: described cable core is made up of light unit and strengthening core, the peripheral closely stranded some strengthening cores in described smooth unit, described strengthening core periphery is coated with multipolymer, described smooth unit is made up of optical fiber and the multipolymer that is coated on optical fiber periphery, and described cable core periphery is coated with sheath.
2. the nonmetal straining sensing optical cable of one according to claim 1, is characterized in that: described strengthening core is aramid fiber reinforcing optical cable reinforced core.
3. the nonmetal straining sensing optical cable of one according to claim 1, is characterized in that: described multipolymer is ethylene-acrylic acid copolymer or ethylene-methacrylic acid copolymer.
