Abstract
The invention discloses an optical cable used for a strain sensing test for deep sea, and is characterized in that light-guide fiber is taken as a strain testing unit, a layer of UV (Ultra Violet) anti-skid curing material layer is coated on the light-guide fiber, a silicone scream jacket is coated on the UV anti-skid curing material layer, and a seamless embossing stainless steel band is longitudinally coated on the silicone scream jacket. The optical cable has the advantages that an embossing stainless steel pipe is taken as a jacket of a strain cable, so that the problem of hydrolysis resistance and seawater corrosion resistance can be solved, the bending performance and the side pressure resistance of the strain cable can be improved through an embossing structure, and meanwhile, friction is improved through a concave-convex structure, and the external force is effectively transferred to an optical fiber; the silicone scream jacket is applied in the optical cable, so that ageing resistance of the optical cable is improved, and meanwhile, the external force is effectively transferred to a fiber core part; the UV anti-skid curing material is utilized on the surface of the optical fiber, so that the optical fiber and the silicone scream are effectively stuck without slippage, thus the optical cable can be used in the waterproof, alkali-resisting and corrosion-resistant deep seat environment.
Description
Technical field
The present invention relates to a kind of optical cable, particularly relate to a kind of deep-sea strain sensing test optical cable.
Background technology
Fiber strain sensing technology extends with optic fibre force to produce the measuring technology that shape becomes background, and main points are when optical cable bears external force, and power can effectively be delivered on optical fiber.Therefore, require, without slippage between optical fiber and protective sleeve, synchronously to extend deformation; existing straining sensing optical cable because structure is simple, material from as plastic material, so be not suitable under water; quoting in special briny environment, the strain testing of many river courses and submarine platform all cannot realize.
Therefore be badly in need of a kind of novel deep sea strain sensing test optical cable, solve this problem existed in existing product.
Summary of the invention
The object of the invention is to overcome the application of existing strain optical cable not under hydrolysis and high side pressure environment, strain optical cable is able under water and adaptable a kind of deep-sea strain sensing test optical cable under deep-marine-environment.
The technical solution used in the present invention is:
A kind of deep-sea strain sensing test optical cable, this optical cable by light transmitting fiber as strain testing unit, described light transmitting fiber is externally coated with one deck UV antiskid curing material layer, be surrounded by silicon cream sheath outside described UV antiskid curing material layer, described silicon cream sheath outside is vertical is surrounded by seamless embossing stainless steel band.
UV antiskid curing material layer by mass percent be the silica gel of 75-85%, the solid gum of mass percent to be the EVA of 10-20% and mass percent be 4-6% forms.
Advantage of the present invention is: adopt embossing stainless-steel tube as the sheath of strain optical cable, to solve hydrolysis and marine corrosion, embossing structure can improve bendability and the lateral pressure resistant character of strain optical cable, and concaveconvex structure can improve friction force, effectively by the transmission of external force to optical fiber simultaneously; Inner adopt silicon cream sheath, improve the resistance to ag(e)ing of strain optical cable, simultaneously can effectively by external force to core segment transmission; Optical fiber surface utilizes antiskid UV curing materials, can realize optical fiber and not produce slippage with the effectively bonding of silicon cream material, and this optical cable can be used under water-fast, alkaline-resisting, corrosion resistant deep-marine-environment.
