Pressure-balanced photoelectric separation device for main submarine base stations

Abstract

The invention relates to the technical field of submarine observation equipment, in particular to a pressure-balanced photoelectric separation device for main submarine base stations. The device includes a submarine cable, an armored steel wire fixing mechanism, a cable core sealing protection mechanism and an oil-filled tank body mechanism. The submarine cable includes an armored steel wire (1) and a submarine cable core (12). The submarine cable core (12) is wrapped with a PE insulating layer, and a copper conductor (13) and an optical fiber unit (16) are arranged inside the submarine cablecore (12). The armored steel wire fixing mechanism is in butt joint with the cable core sealing protection mechanism, and the cable core sealing protection mechanism is in butt joint with the oil-filled tank body mechanism. The submarine cable is inserted into the armored steel wire fixing mechanism, and passes through the cable core sealing protection mechanism to the inside of the oil-filled tank body mechanism. The copper conductor (13) is connected through electrical leading with an electrical cable cabin-penetrating part (15) arranged at the end of the oil-filled tank body mechanism. Theoptical fiber unit (16) is directly welded to an optical cable cabin-penetrating part (18). The problem that a submarine cable core creeps into a photoelectric separation cabin under the pressure of deep water is solved.

Description

Technical field [0001] The invention belongs to the technical field of seabed observation equipment and seabed observation network, and specifically relates to a pressure balance type seabed main base station photoelectric separation device. Background technique [0002] The submarine observation network is a marine observation network formed by connecting shore-based equipment, photoelectric composite cables, and submarine main base stations. The submarine main base station is an important device for power conversion, data convergence, transmission and control. The photoelectric separation device used to connect the submarine cable is an important component of the submarine main base station. It mainly separates the high-voltage electrical copper conductor from the signal fiber. Connect the power conversion unit and the data convergence transmission and control unit respectively. The photoelectric separation device is generally fixed on the base of the submarine main base stati...

AI Technical Summary

Problems solved by technology

In this structure, when the submarine cable enters the optoelectronic separation cabin, only the outer armor is fixed; however, the cable core and the cabin are in a relatively free state. Static pressure will cause the cable core to creep into the photoelectric separation chamber, eventually causing displacement or deformation of the O-shaped or V-shaped sealing ring, resulting in the failure of the seal where the cable core passes through the photoelectric separation chamber, and then insulation failure. performance cannot meet the long-term work requirements of the photoelectric separation device in deep water conditions
