Sensor.
Background technology
Liquid leakage is the big chronic disease in engineering, for conductive liquids such as water, can be placed using the cable being powered
In monitored area, when occurring fluid seepage, the liquid conduction leaked out causes resistance of cable etc. to produce change, passes through meter
Calculate variable quantity, it is possible to detect the position leaked.
Crude oil and petroleum-type liquid fuel do not have electric conductivity, and belong to inflammable explosive article, are carried out using electric induction mode
The technical scheme of measurement is defective in itself.The detection method of traditional crude oil leakage, mainly there is following several：
Observation：By methods such as artificial visual, ultrasonic listening, infrared photographies, to crude oil leakage point, the oil leaked out
Mark etc. is observed, and searches out leak position.This method simple, intuitive, but detection efficiency is low, working strength big, by people employee
Make state influence big, and be difficult that effectively concealment part is observed.
Magnetic Flux Leakage Inspecting：To metal pipe-wall magnetize after, leak produce leakage magnetic flux, by detecting instrument obtain magnetic flux come
Know the degree of injury of tube wall.But magnetic leakage signal or sensor can be influenceed by pressure, place environment of pipeline etc. in itself, lack sensitive
Degree, easily produces and fails to judge, judges by accident.
Suction wave-discharge method：When occurring crude oil leakage, because of fluid media (medium) loss, leakage point produces localized liquid immediately
Reduce, the instantaneous pressure reduction of appearance is propagated to the upstream and downstream of leakage point by fluid media (medium) as pressure wave source, passes through monitoring
Suction wave and flow are judged and positioned to pipe leakage.Suction wave-discharge method implementation method is simple, but in actual environment
Central Plains oil pressure, flow have fluctuation, and result of calculation has error, while crude oil flow slowly or is not flowed, and leakage point
Smaller occasion testing result is undesirable.
In addition, the change such as vibration, pressure wave, temperature for being produced also by measurement leak position liquid injection, indirectly right
Crude oil leakage is detected, although can be played a role in specific occasion, but measurement accuracy rate is not high, wideless using scope.With
The development of optical fiber technology, fiber optic sensor system has obtained certain application, fibre optical sensor system in terms of crude oil leakage detection
Important device in system makes fibre-optical sensing device, and existing fibre-optical sensing device mainly has：
Optical fiber prism sensing device：Prism is connected on optical fiber, when gear prism bases contact different types of liquid, its
Transmission loss is different, and light intensity can also produce change.The change of light intensity is received by measuring, monitors whether occur crude oil leakage.
Plastic overmold silica fibre sensor device：Covering is penetrated into when crude oil and optical fiber contact, causes clad refractive
Rate changes so that the light effusion optical fiber in optical fiber, causes the transmission loss of optical fiber to raise, light intensity changes.Connect by measurement
The change of light intensity is received, monitors whether occur crude oil leakage.
Although above-mentioned optical fiber sensor device is because passive feature, crude oil and petroleum-type liquid fuel are suitably applied in
Leakage monitoring occasion, but it is complicated, inconvenience is installed in practical matter.Simultaneously as site environment is more severe, there is oil
The particles such as mist, dust, easily stain prism surface, damage plastic envelope, and then influence the measurement accuracy of sensor.
Utility model content
It is complicated in order to solve optical fiber sensor device, in practical matter install inconvenience, easily stain prism surface,
Plastic envelope is damaged, and then influences the technical problem of the measurement accuracy of sensor, the utility model provides a kind of simple in construction,
It is easy for installation in practical matter, prism surface will not be stained, plastic envelope will not be damaged, the measurement accuracy of sensor is high
