Description

一种海底光电复合缆深海终端分离装置Submarine photoelectric composite cable deep-sea terminal separation device 技术领域Technical field

当前在海洋科学研究、海底资源开发、水下环境监测等领域中，长时间实时远程观测水下环境的需要越来越强烈，由于电缆通信***难以实现远距离、大容量的数据传输，因此需要采用以光电复合通信海缆作为信号传输介质的光纤通信***。为实现岸端基站与水下设备之间的实时数据传输和电能传输，必须通过水下光电分离器将光电复合海缆中的通信光纤和供电导体在水下进行分离后接入主接驳盒中，进而再通过水密电缆将主接驳盒与次级接驳盒进行连接。设计的海底光电分离器一般要求易于安装、应用在不同海洋工程装备上的兼容性好、长时间运行时稳定性好。At present, in the fields of marine scientific research, seabed resource development, and underwater environment monitoring, the need for long-term real-time remote observation of the underwater environment is becoming increasingly strong. Because cable communication systems are difficult to achieve long-distance, large-capacity data transmission, An optical fiber communication system using a photoelectric composite communication submarine cable as a signal transmission medium is used. In order to realize the real-time data transmission and power transmission between the shore-side base station and the underwater equipment, the communication optical fiber and power supply conductor in the photoelectric composite submarine cable must be separated into the main junction box through the underwater photoelectric separator. In the meantime, the main junction box and the secondary junction box are connected by a watertight cable. Designed submarine photoelectric separators generally require easy installation, good compatibility in different marine engineering equipment, and good stability during long-term operation.

In addition, the commonly used photoelectric composite cable in the industry The self-locking method of pressure armor requires special operating tooling, and it is easy to damage the outer armor wire of the photoelectric composite cable, which needs to be improved.
