Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The utility model provides a submarine cable nondestructive test device, as shown in FIG. 1, the device can carry out nondestructive test to the cable by oneself at the seabed, and detection efficiency is high, and convenient operation does not influence submarine cable's normal use.
The nondestructive testing device for submarine cables shown in fig. 1 comprises an oil cylinder 3 with a through hole 1 formed in the center and capable of being sleeved on a cable 2, a driving motor 4 arranged at one end of the oil cylinder 3, and a cleaning wheel 6 driven by the driving motor 4 and a transmission mechanism 5 to rotate, wherein the cleaning wheel 6 is sleeved on the cable 2, a tool bit is arranged outwards, and a polishing layer is arranged on the inner wall of the cleaning wheel 6.
As shown in fig. 2 and 3, the other end of the oil cylinder 3 is provided with a pump 7, a lighting lamp 8, an optical probe 9 and a power supply and controller 10, the outer wall of the oil cylinder 3 is wrapped with an oil bag 11, and the oil cylinder 3 and the oil bag 11 are connected through the pump 7. Four groups of illuminating lamps 8 and optical probes 9 are arranged and are uniformly distributed along the radial direction of the through hole 1 in the center of the oil cylinder 3.
The power supply provides electric energy for other parts in the device, and the controller is in signal connection with the driving motor 4, the pump 7, the illuminating lamp 8 and the optical probe 9. The controller is internally provided with a storage chip which can store detected data and provide data support for the overhaul of the submarine cable.
The utility model provides a submarine cable nondestructive test device passes through driving motor 4, drive mechanism 5 drives clearance wheel 6 and clears up the debris on cable 2 surfaces, the wool layer of clearance wheel 6 inner walls can polish cable 2, expose cable 2 surfaces, under illumination of light 8, optical probe 9 gathers the chart sequence in surveyed the region, phase information through every pixel of software analysis corresponds the heat wave signal, utilize phase information to construct and detect the characteristic image, differentiate defect position and size on the cable under water through the difference information among the analysis characteristic image.
