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.
