Abstract
The utility model discloses a kind of piping displacement sensor based on Fibre Optical Sensor, it is characterised in that：It includes base, optical fiber, fibre clip and gangbar；The fibre clip is floated and is arranged on the base；Described gangbar one end is fixedly connected in the fibre clip, and the other end is connected with pipeline；The optical fiber enters from fibre clip side, is drawn after being wound a ring or multiple ring in the fibre clip from the opposite side of the fibre clip.The utility model is linked together pipeline and fibre clip by a gangbar, when pipeline produces displacement, the movement of gangbar is driven, the movement of gangbar make it that fibre clip generates displacement again, pressure is generated to winding optical fiber therein, generate optical fiber micro-bend, the bending can be measured by general OTDR optical time domain reflectometers, so as to measure the displacement of pipeline.This Sensor Design is simple, it is possible to achieve over long distances, in real time monitoring, while in measurement range, it is not necessary to power.
Description
Technical field
The utility model belongs to technical field of optical fiber sensing, and more particularly to a kind of piping displacement based on Fibre Optical Sensor is passed
Sensor.
Background technology
In existing urban duct, displacement measurement of the pipeline based on support is also mainly manually patrolled, it is difficult to accomplish in real time
Monitoring.Also there is the device using electric displacement sensor remote monitoring piping displacement in the prior art, but electric displacement sensor is difficult
In installation, the popularization for the electric transducer that the power supply of long range is also limited.Also have in the prior art using fiber-optic grating sensor come
The technical scheme of remote monitoring oil pipe, but many (FBG) demodulators are needed in the case of long range measurements, while optical fiber grating sensing
The encapsulation of device is also difficult point.
The content of the invention
The utility model purpose be for existing sensor defect provide one kind can over long distances, real-time monitoring tubular
The piping displacement sensor based on Fibre Optical Sensor of the displacement in road.
The utility model to achieve the above object, is adopted the following technical scheme that：
A kind of piping displacement sensor based on Fibre Optical Sensor, it is characterised in that：It include base, optical fiber, fibre clip and
Gangbar；The fibre clip is floated and is arranged on the base；Described gangbar one end is fixedly connected in the fibre clip, separately
One end is connected with pipeline；The optical fiber enters from fibre clip side, from institute after being wound a ring or multiple ring in the fibre clip
The opposite side for stating fibre clip is drawn.
It is further characterized by：The fibre clip has the jig arm of many radial settings, the jig arm outboard end
Set fluted, the optical fiber is embedded in the groove；Jig arm groove corresponding with the jig arm quantity is provided with the base,
The jig arm is absorbed in the jig arm groove, and the optical fiber is arranged on fibre clip described in the upper surface float support of the base.
It is preferred that：The jig arm is the six roots of sensation, is uniformly distributed.
The jig arm well width is more than the jig arm width, and the jig arm slot length is more than the jig arm length.
The base, optical fiber, fibre clip and gangbar overall package are in a closed housing, and the housing is provided with
Optical fiber is imported and exported and gangbar outlet.
The utility model is linked together pipeline and fibre clip by a gangbar, when pipeline produces displacement, band
The movement of gangbar is moved, the movement of gangbar make it that fibre clip generates displacement, pressure is generated to winding optical fiber therein again
Power, generates optical fiber micro-bend, the bending can be measured by general OTDR optical time domain reflectometers, so as to measure pipeline
Displacement.
Compared with prior art, the beneficial effects of the invention are as follows the Sensor Design is simple, it is possible to achieve over long distances, in real time
Monitoring, while in measurement range, it is not necessary to power.

Described one end of gangbar 4 is fixedly connected in the fibre clip 3, and the other end is connected with pipeline；The optical fiber 2 from
The side of fibre clip 3 enters, and is drawn after being wound a ring or multiple ring in the fibre clip 3 from the opposite side of the fibre clip 3.
The base 1, optical fiber 2, fibre clip 3 and the overall package of gangbar 4 are in a closed housing, and the housing is set
Optical fiber is equipped with to import and export and gangbar outlet.
The utility model is installed as shown in Fig. 2 base can be fixed on support of pipelines by screw in compression, and pipeline is in itself
It is connected with gangbar.Pipeline is simultaneously mobile relative to the mobile gangbar that can cause piping displacement sensor of its support of pipelines,
The movement of gangbar, can cause fibre clip to be moved to a direction, pressure is generated to the optical fiber in same direction, so as to make
It is being the size and location of detectable optical fiber micro-bending by common OTDR optical time domain reflectometers into the micro-bend of optical fiber, so that
It was found that displacement and direction of displacement situation of the pipeline relative to support of pipelines.
