Umbilical cable photoelectric separator of underwater vehicle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to an umbilical cable photoelectric separation device. Background technique [0002] The umbilical cable is a key component of the cable-controlled underwater vehicle, which provides energy for the vehicle and realizes real-time communication between the vehicle and surface equipment. It includes power supply cables and communication optical fibers. After the umbilical cable is connected to the aircraft, photoelectric separation is required to separate the power supply cable and communication optical fiber to connect with the energy system and communication system of the aircraft, so as to realize continuous and uninterrupted supply of high-voltage electric energy and real-time communication. In general umbilical cables, the cables and communication optical fibers are separated directly at the end of the cables or through connectors. This separation method has potential ...

AI Technical Summary

Problems solved by technology

Generally, the umbilical cable is used to directly separate the cable from the communication optical fiber at the end of the cable or through the connector. This separation method has potential safety hazards for high-voltage power supply, and it is easy to cause damage to the optical fiber during long-term use. At the same time, this method limits the communication between the umbilical cable and The connection method of the aircraft, that is, from the tail, is inconvenient for installation and maintenance
