Abstract

The utility model provides a kind of seabed liquid transporting flexible pipe, includes bellows, cushion, back-up coat, thermal insulation layer, waterproof thermal insulation layer and waterproof layer successively from the inside to the outside;The cushion is close on the bellows, and the back-up coat is close on the cushion;Wherein, fibre optic temperature sensor is provided between the thermal insulation layer and the waterproof thermal insulation layer, the fibre optic temperature sensor is spiral and is continuously wrapped in the periphery of the thermal insulation layer.Thus, cushion is filled by being attached at bellows the space the ripple on bellows, so as to be easy to the stable of back-up coat to install;And flexible pipe inner corrugated pipe can be monitored in real time by fibre optic temperature sensor and whether thermal insulation layer leaks, and can further be protected by waterproof thermal insulation layer and waterproof layer, prevent leakage.

Description

A kind of seabed liquid transporting flexible pipe
Technical field
The utility model is related to seabed liquid transporting flexible pipe, for will the cryogen such as liquefied natural gas from sea Floating marine facility be transported to oil tanker etc., and for detecting the situation of this soft tube fluid leakage.
Background technology
Traditionally, should when the oil for originating from seabed is loaded onto from marine floating facility to be stored on Tanker-Transport Floating facility and oil tanker are linked together by using floating hose, and the oil or the like need to be conveyed by flexible pipe.So And current flexible pipe easily causes leakage and flexibility is not enough, it is impossible to meet the transport of subsea cryogenic fluid.
Utility model content
The defect that flexible pipe is easily leaked in transport in order to overcome prior art subsea cryogenic fluid, it is proposed that one kind can be real When monitoring flexible pipe hydrodynamic and place fluid leakage seabed liquid transporting flexible pipe.
To achieve these goals, the technical scheme that the utility model is used is:
A kind of seabed liquid transporting flexible pipe, includes bellows, cushion, back-up coat, thermal insulation layer, no successively from the inside to the outside Permeable thermal insulation layer and waterproof layer;The cushion is close on the bellows, and the back-up coat is close to the cushion On;Wherein, fibre optic temperature sensor, the optical fiber sensing are provided between the thermal insulation layer and the waterproof thermal insulation layer Device is spiral and is continuously wrapped in the periphery of the thermal insulation layer.
Further, the fibre optic temperature sensor includes metal tube and the optics being inserted into inside the metal tube is fine Dimension.
Further, the optical fiber is than the metal pipe range so that optical fiber with bellows or The integrally bending of flexible pipe and bend.
Further, the fibre optic temperature sensor is equidistantly wrapped on the thermal insulation layer periphery, and the spacing is 100- 200 mm.Once generation fluid is leaked, then fibre optic temperature sensor will sense the change of environment temperature, so as to effectively fixed The position of position leakage.
Further, the end of fibre optic temperature sensor is connected with light source, optical branching device, amplifier and measurement apparatus.
Further, the back-up coat is that stainless steel band is wrapped in formation on the cushion, and stainless steel band formation first With the second winding layer, first and second winding layer intersects overlapping, and the coiling direction phase of the first and second winding layers Instead.
The winding spacing of further described stainless steel band is more than the width of the stainless steel band.Increase while cost-effective The dynamics of strong back-up coat.
Using technical solutions of the utility model, the position of soft tube fluid leakage, and anti-fluid stopping simultaneously can be effectively monitored Outside body leak flexible pipe.
Brief description of the drawings
Fig. 1 is hose construction schematic diagram in the utility model specific embodiment;
Fig. 2 is the sectional view of fibre optic temperature sensor in the utility model specific embodiment.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other It can just be mutually combined.
As shown in Figure 1, a kind of seabed liquid transporting flexible pipe 10, includes bellows 1, cushion 2, adds successively from the inside to the outside Gu layer 3, thermal insulation layer 4, waterproof thermal insulation layer 5 and waterproof layer 6;Cushion 2 is close on bellows 1, and back-up coat 3 is close to slow Rush on layer 2;Wherein, fibre optic temperature sensor 7, fibre optic temperature sensor 7 are provided between thermal insulation layer 4 and waterproof thermal insulation layer 4 Periphery that is spiral and being continuously wrapped in thermal insulation layer 4.Thus, cushion 2 is by being attached at bellows 1, on bellows 1 Space between ripple is filled, so as to be easy to the stable of back-up coat 3 to install;And can be with by fibre optic temperature sensor 7 Whether the monitoring inner corrugated pipe 1 of flexible pipe 10 and thermal insulation layer 4 leak in real time, and can pass through waterproof thermal insulation layer 5 and waterproof Layer 6 is further protected, prevent leakage.
In the utility model specific embodiment, fibre optic temperature sensor 7 includes metal tube 71 and is inserted into metal tube 71 Internal optical fiber 72.Preferably, optical fiber 72 is longer than metal tube 71, so that optical fiber 72 is with ripple The integrally bending of pipe 1 or flexible pipe 10 and bend.
In the utility model specific embodiment, fibre optic temperature sensor 7 is equidistantly wrapped on the periphery of thermal insulation layer 4, excellent Selection of land, spacing is 100-200 mm.Once generation fluid is leaked, then fibre optic temperature sensor will sense the change of environment temperature Change, so as to the position of effectively positioning leakage.
In the utility model specific embodiment, the end of fibre optic temperature sensor 7 is connected with light source, optical branching device, amplification Device and measurement apparatus(It is not shown here).
In the utility model specific embodiment, back-up coat 3 winds for stainless steel band 31 and formed on the buffer layer 2, and not Become rusty the first winding layer 311 of formation of steel band 31 and the second winding layer 312, and the first winding layer 311 and the second winding layer 312 intersect It is overlapping, and the coiling direction of the first winding layer 311 and the second winding layer 312 is opposite.
In the utility model specific embodiment, the winding spacing of stainless steel band 31 is more than the width of stainless steel band 31.Save Strengthen the dynamics of back-up coat while cost.
Using technical solutions of the utility model, the position of soft tube fluid leakage, and anti-fluid stopping simultaneously can be effectively monitored Outside body leak flexible pipe.
The utility model preferably embodiment is these are only, but protection domain of the present utility model is not limited to This, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this Within the protection domain of utility model.
