Abstract
The utility model discloses a pipeline strain fiber sensor monitoring device based on a high elasticity characteristic of rubber. The device comprises a rubber sleeve pipe, a fiber, and a photoelectric conversion signal interface. The fiber is annularly embedded in the rubber sleeve pipe in a spiral manner. The end part of the fiber is connected to the photoelectric conversion signal interface. The rubber sleeve pipe is firmly attached to the outwall of the pipeline through an adhesive. The outer side of the rubber sleeve pipe is covered by an anticorrosive layer. Compared with other devices, the monitoring device is advantaged by being simple in structure, convenient in material obtaining process, efficient in installation, essential in explosion resistance, low in invested cost, and relatively simple in demodulation signal, and then detection efficiency is improved.
Description
Technical field
The utility model is a kind of pipeline strain monitoring device, can be shifted for various pipes, the strain monitoring of local deformation, crackle, is specifically related to a kind of pipeline strain Fibre Optical Sensor monitoring device based on rubber high resiliency characteristic.
Background technology
In use, due to the impact of the unfavorable factors such as effect, fatigue effect, corrosion and the material aging of environmental load, structure will inevitably produce damage accumulation to all kinds of oil and gas pipes and drag decays, thereby cause the generation of calamitous burst accident.The field of oil and gas pipes accident direct relation national economy, casualties, economic loss and the social influence that accident causes is all very huge.Pipe-line ess-strain situation complexity.In the time of pipeline discontinuity, pipeline stress balance state is destroyed, and local deformation can occur pipeline, produces corresponding displacement, flexing or creep, and then unstable fracture.The technology existing at present, generally has detection resolution low, and signal transmission and demodulated complex, be subject to the features such as complex environment impact.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and a kind of pipeline strain Fibre Optical Sensor monitoring device based on rubber high resiliency characteristic is provided.
A kind of pipeline strain Fibre Optical Sensor monitoring device based on rubber high resiliency characteristic of the utility model, comprises gum sleeve, optical fiber and photosignal translation interface; Optical fiber is embedded in gum sleeve by spiral way annular, and the end of optical fiber is connected to photosignal translation interface, adopts adhesive that gum sleeve is tightly pasted on pipeline outer wall, and lays anticorrosive coat in gum sleeve outside.
The pitch of described optical fiber 2 is 30cm-50cm.
Described gum sleeve: the material of gum sleeve is that a class has elastomeric macromolecular material, is also called as elastic body.Be subject to less external force effect under there is very large deformability, length growth rate can reach 500 to 1000%.
The advantages such as the utility model device is compared to be had simple in structurely with other devices, draws materials conveniently, and it is convenient to install, and essence is explosion-proof, and input cost is low, and restituted signal is relatively simple have improved detection efficiency simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is paving mode figure of the present utility model.
In figure, 1, gum sleeve, 2, optical fiber, 3, anticorrosive coat, 4, photosignal translation interface, 5, pipeline.
Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
As shown in Figure 1, 2, a kind of pipeline strain Fibre Optical Sensor monitoring device based on rubber high resiliency characteristic, comprises gum sleeve 1, optical fiber 2 and photosignal translation interface 4; Optical fiber 2 is embedded in gum sleeve 1 by spiral way annular, the pitch of optical fiber 2 is 30cm, the end of optical fiber 2 is connected to photosignal translation interface 4, adopts adhesive that gum sleeve 1 is tightly pasted on pipeline 5 outer walls, and lays anticorrosive coat 3 in gum sleeve 1 outside.
Optical fiber adopts 50/125um multi-mode communication optical fiber, and adhesive is " cyanoacrylate (502) " adhesive.
When pipeline is shifted, when local deformation, can produce corresponding displacement stress, flexing or creep, the effect of power is passed to the gum sleeve being wrapped in outside pipeline, make gum sleeve that corresponding deformation occur, high resiliency characteristic based on rubber, under less External Force Acting, produce larger deformation, the deformation that rubber produces acts on again the optical fiber of imbedding rubber, when optic fibre force is inhomogeneous, fiber axis produces small irregular curved, by the variation of the light conducting power in optical fiber, the light intensity of passing through in optical fiber can be weak, transform by photosignal, detect displacement or pressure size.Interface unit 4 is the interface of photosignal conversion, and the distance between two interface units, determines as required.
