Description
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.
