Description

A kind of optical cable infiltration detection device
Technical field
This utility model relates to optical cable detection technique field, especially a kind of optical cable infiltration detection device.
Background technology
In prior art, optical cable infiltration detection device includes that the various penstocks on pressurize water column, horizontal water tank, branch's water pipe and water valve, base are connected to block adapter.The water peak of optical fiber can be caused to decay after optical cable infiltration, after water penetration optical cable, meeting corrosion the optical cable that fractures, optical cable needs when dispatching from the factory to carry out optical cable infiltration test, ensureing that optical cable 100% will not seep water, existing detection device is not easy to observe tank pressure situation of change, simultaneously complex operation.
Utility model content
The purpose of this utility model is the problems referred to above existed for existing technology, provide a kind of optical cable infiltration detection device, this utility model device solves tank pressure change inconvenience metering and the problem of complex operation, make variation in water pressure can control in the range of ± 2g by pressure tester, only need to operate on the controller, simple and efficient to handle.
To this end, the technical solution that this utility model is taked is:
A kind of optical cable infiltration detection device, including water tank, press water supply station, fiber cable joint device, pressure tester, controller, water tank is respectively provided with press water supply station and fiber cable joint device in both sides, the compression pump of press water supply station is connected on water tank by supply channel, the signal piping of fiber cable joint device is connected on water tank, supply channel is provided with electrodynamic valve, signal piping is provided with electric flow valve, water tank bottom is provided with pressure tester, and electrodynamic valve, electric flow valve and pressure tester connect on the controller.
As further preferably, described pressure tester is differential pressure transmitter.
As further preferably, described controller is provided with alarm.
Having the beneficial effects that of technique scheme:
This utility model device is provided with pressure tester at water tank bottom, i.e. differential pressure transmitter, when opening electric flow valve, if there is infiltration in optical cable, occurring in water tank beyond pressure differential resetting value, controller provides warning warning, and accuracy in detection and simple operation to optical cable are the most excellent, in prior art, pressurize water column valid analysing range is at least at more than 3g, and trigger valve operation is loaded down with trivial details simultaneously;This utility model apparatus structure is simple, reduces detection labor intensity.

Detailed description of the invention
For making feature of the present utility model and advantage clearer, it is described below in conjunction with specific embodiment.
As shown in Figure 1, a kind of optical cable infiltration detection device, including water tank 1, press water supply station 2, fiber cable joint device 3, pressure tester 4, controller 5, water tank 1 is respectively provided with press water supply station 2 and fiber cable joint device 3 in both sides, the compression pump 201 of press water supply station 2 is connected on water tank 1 by supply channel 202, the signal piping 301 of fiber cable joint device 3 is connected on water tank 1, supply channel 202 is provided with electrodynamic valve 203, signal piping 301 is provided with electric flow valve 302, pressure tester 4 it is provided with bottom water tank 1, electrodynamic valve 203, electric flow valve 302 and pressure tester 4 are connected on controller 5.
In the present embodiment, described pressure tester 4 is differential pressure transmitter, the small pressure reduction change of water tank 1 can be fed back, solve pressurize water column and observe inaccurate problem, expand optical cable infiltration detection range, accuracy of detection can reach ± 2g within, even if small water seepage hole occurs, also can accurately detect, meet higher infiltration testing requirement.
In the present embodiment, described controller 5 is provided with alarm, and fiber cable joint device 3 and optical cable junction exist water surplus, when the metering of electric flow valve 302 and the metering of pressure tester 4 are beyond setting difference, alarm provides warning warning, and prompting current detection optical cable exists seepage problem.
During use, controller 5 is opened electrodynamic valve, the hydraulic pressure in water tank 1 is made to reach to detect in range hydraulic pressure, optical cable is fixed on fiber cable joint device 3, controller 5 starts electric flow valve 302, connection space surplus filled up by water tank 1, i.e. beyond setting difference, controller 5 is reported to the police, close electric flow valve 302, warning warning is not given without departing from setting difference controller, after pressurize 5s ~ 10s, it is automatically switched off electric flow valve 302, complete when time detection, pressure tester 4 makes zero with the difference of electric flow valve 302 simultaneously, when water tank 1 hydraulic pressure can not meet testing requirement, it is again turned on electrodynamic valve 203, repeat above-mentioned detection circulation.
In addition to the implementation, this utility model can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within protection domain of the present utility model.
