Abstract
The utility model discloses a pre -buried stress temperature sensing optical cable in RTP pipe, including fiber optic assembly, stretching resistant element and oversheath, its characterized in that: still including the light unit, the light unit is including pine sleeve pipe and tight coated fibers I, the transversal rounded rectangle structure of personally submitting of oversheath. The light unit adopts pine sleeve pipe and I structure of built -in tight coated fibers, and tight coated fibers's I diameter be 0.6mm, and the structural design of this kind one tight one pine sensing accurately arrives external stress and temperature, makes the whole external diameter of optical cable reduce moreover, and it is pre -buried to be more convenient for.
Description
Technical field
The utility model is related to a kind of stress and temperature sensing optical cable, relates in particular to a kind of reinforced thermoplastics
Multiple tube（Abbreviation RTP）In pre-buried stress temperature sensing optical cable, the state in real-time monitoring RTP road, so as to ensure pipeline
Safety.Belong to nonmetal flexible pipeline intelligent monitoring technical field.
Background technology
World's oil pipeline resource is extremely enriched, and the contention of countries on petroleum resource is also growing more intense.Petroleum gas is opened
Adopt industry past major part and adopt steel pipe market, most distinct issues are exactly the leakage of the oil that corrosive pipeline is caused or natural gas.
The long range monitoring of pipeline is pressed close to pipeline and is laid in the same direction using ordinary optical cable, and construction requirement is higher, and there is forecast not in time, calmly
Position low precision, the shortcomings of rate of false alarm is high.
More employing RTPs of newly-built Oil and Natural Gas Transportation Pipeline at this stage, RTP is compound for reinforced thermoplastics
Pipe, it is commonly used in the conveying of oil field petroleum gas at sea, but the real-time monitoring of pipeline becomes a difficult point, therefore can
Optical cable for sensing carried out in the production process of RTP pre-buried.However, also do not have a disclosure satisfy that RTP is pre-buried at present
Optical cable.
Utility model content
Technical problem to be solved in the utility model is to put forward a kind of little size, high temperature resistant, easily separated, lateral pressure resistant, tension
The stress temperature sensing optical cable stretched.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
Pre-buried stress temperature sensing optical cable in a kind of RTP, including optical fiber component, tensile elements, light unit and oversheath,
The light unit includes Loose tube and tightly packaged fiber I, the rounded rectangular configuration in cross section of the oversheath.
The first scheme, the optical fiber component is made up of two tightly packaged fibers II, the tensile elements, two tightly packaged fibers
II and light unit it is in the same plane.
Another program, the optical fiber component is made up of two colored optical fibers, and two colored optical fibers are disposed side by side on anti-
Draw between element and light unit.
Further, it is provided with the tearing port being easily peeled off on the oversheath.
Further, a diameter of 0.6mm of the tightly packaged fiber I.
Further, the Loose tube is PBT Loose tubes.
Further, the tensile elements are FRP tensile elements.
The utility model has the advantages that：
1）The cross section of oversheath is round rectangle structure（That is flat）So that the stress of sensing optical fiber is heated feedback letter
It is number more accurately and steady, while also beneficial to the pre-buried laying of optical cable.
2）Light unit is using Loose tube and the structure of built-in tightly packaged fiber I, a diameter of 0.6mm of tightly packaged fiber I, and this one is tight
The structure design of one pine can not only be precisely sensed extraneous stress and temperature, and the entire outer diameter of optical cable is reduced,
It is more convenient for pre-buried.
3）Protected using PBT Loose tubes, with lightweight, external diameter it is little, intensity is high, the effect that block-water performance is good.
4）Tensile elements adopt FRP material, with good transmission performance and environmental performance, and whole optical cable without
Electricity, has the advantages that essential explosion-proof, lightning protection, anticorrosion, electromagnetism interference, can in hostile environment trouble free service.

Element 4, light unit and oversheath 2, light unit includes PBT Loose tubes 3 and tightly packaged fiber I 5, and the cross section of oversheath 2 is rounded
Rectangular configuration.Light unit is placed between two tightly packaged fibers II 1, and FRP tensile elements 4 are placed in one tightly packaged fiber II 1
By side.Accurate and real-time is sensed in order to further improve, by FRP tensile elements 4, two tightly packaged fibers II 1 and light units
It is disposed on the same plane.In order to reduce the overall dimensions of optical cable, the size of the employing 0.6mm of tightly packaged fiber I.
Embodiment 2
As shown in Fig. 2 the optical fiber component of the present embodiment is made up of two colored optical fibers 6, two colored optical fibers 6 are arranged side by side
Between FRP tensile elements 4 and light unit, and the tearing port 7 being easily peeled off is provided with oversheath 2.Other structures are with real
Apply example 1.
Uninterrupted all-pass road detection in whole 24 hours can be carried out using optical cable for sensing of the present utility model, to operation maintenance
Work brings technical revolution change.Can be widely applied to the reservoir parameter detection of petroleum gas down-hole（Including temperature
Degree, pressure）, understanding of the Koolaj-Es Foldgazbanyaszati Vallalat to reservoir is greatly enriched, it is easy to optimize exploitation of oil-gas field and maintenance.
