The invention relates to the technical field of an
underwater vehicle, and specifically relates to an
umbilical cable photoelectric separator. The
umbilical cable photoelectric separator of an
underwater vehicle comprises a seal housing, an oil charge valve, an
exhaust valve, a hydraulic position spring, a
fiber interface, a cable interface and an
umbilical cable fixing structure, wherein the
fiber interface and the cable interface are watertight connectors; when the
underwater vehicle works, the
exhaust valve is opened; the oil charge valve is connected with an oil tube, and fills the seal housing with oil according to the practical
water depth and the position of the hydraulic position spring; after completion of oil filing, the seal housing is arranged at the reserved position of the
underwater vehicle, and the umbilical cable fixing structure is fixed; and a
fiber and a power supply cable of the
underwater vehicle are respectively connected with the fiber interface and the cable interface. The umbilical cable photoelectric separator of an
underwater vehicle solves the problem that when the umbilical cable of a current cable-controlled underwater vehicle directly performs photoelectric separation from the
tail of the cable, the fiber is easy to damage and the safety is lower and usage and maintenance is not convenient, and can satisfy various working
water depth requirementsby adjusting the internal
oil pressure.
