Abstract
The utility model discloses a kind of optical protective cover of resistance to environment high strength, comprise back-up coat, reinforcement, pressure release layer, insulation course, back-up coat is positioned at optical protective cover innermost layer, back-up coat wraps fiber body, wrapped up by some reinforcements outside back-up coat, be enclosed with pressure release layer outside reinforcement, outside pressure release layer, be enclosed with insulation course; The utility model has advantage that is corrosion-resistant, compressive resistance.
Description
Technical field
The utility model relates to cable, specifically a kind of optical protective cover of resistance to environment high strength.
Background technology
The optical fiber that current China underground for probing measurement equipment is used, all needs to protect optical fiber.Present stage, mostly the safeguard measure to light be, at optical fiber additional stainless steel spiral wire sleeve pipe, to protect optical fiber injury-free.There are following two point defects in this design: 1, stainless steel spiral wire sleeve pipe uses in down-hole all the year round, and resistance to environment is bad, easily the damages such as corrosion occurs; 2, optical fiber is throughout the year in underground activities, and the pressure of underground and other environmental factors can affect the use of optical fiber, and stainless steel spiral wire sleeve pipe can not effectively address this problem.
Utility model content
The purpose of this utility model is to provide a kind of optical protective cover of resistance to environment high strength, has advantage that is corrosion-resistant, compressive resistance.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: a kind of optical protective cover of resistance to environment high strength, comprise back-up coat, reinforcement, pressure release layer, insulation course, back-up coat is positioned at optical protective cover innermost layer, back-up coat wraps fiber body, wrapped up by some reinforcements outside back-up coat, outside reinforcement, be enclosed with pressure release layer, outside pressure release layer, be enclosed with insulation course.
Back-up coat is worked out by high strength aramid fiber yarn.
Reinforcement is made up of fibre-reinforced plastics.
Pressure release layer is made up of waterproof material, and pressure release layer inner hollow, hollow space is filled with lubricating oil.
Insulation course is made up of teflon.
In the utility model, sheath innermost layer is provided with back-up coat, can increase sheath intensity, guarantees that sheath can not fracture in pulling process; Back-up coat skin is provided with some reinforcements, makes sheath be provided with good anti-extrusion ability and mechanical property; Be provided with pressure release layer outside reinforcement, pressure release layer has good anti-pressure ability, and optical fiber can be protected from the impact of ambient pressure; Sheath outermost is provided with insulation course, and insulation course is made up of teflon, and this material environmental resistance is good, has the features such as corrosion-resistant, fire-retardant, can work in high temperature, wet environment all the year round.
The beneficial effects of the utility model: this cable has advantage that is corrosion-resistant, compressive resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, back-up coat; 2, reinforcement; 3, pressure release layer; 4, insulation course.
