4000m深海科考重型ROV成套系统设计及应用

Design and Application of a 4000 m Work-class ROV System for Deep-sea Scientific Exploration

以深海生态无人科学考察4000m以上的作业水深、150马力@50Hz作业功率、具备多样性科考工具搭载能力及远程操控等功能为设计目标,文章给出了一种科考级重型ROV成套系统的设计方案。其采用了ROV本体轻量化高功率密度、5级海况下自排缆双冗余驱动收放、便捷分布式紧凑型水面远距离供电控制及组合式作业工具等设计技术,可实现ROV本体4000 m飞行、安全布放回收及无人深海科考作业等功能,且部分部件可推广应用于6000m平台。最后,基于油压补偿推进器、灯控箱、工具阀箱及水下电子舱等关键自制零部件,研制了ROV成套系统工程产品;并通过单体部件级、子系统级及整机系统级测试,以及首次海试和9天8个潜次的深海生态科考任务,取得了大量科考样本和数据,有效检验了该ROV系统的作业能力及可靠性。

Targeting deep-sea ecological unmanned scientific research in operation waters exceeding 4000 meters with operating power of 150 HP@50 Hz,the capability to carry diverse scientific research tools,and remote control functionalities,this paper proposes a design solution for a complete scientific work-class ROV system.The system employs design techniques of lightweight,high power-density ROV body,self-discharging double redundancy drive under Sea State 5 for cable deployment and recovery,conveniently-distributed and compact surface remote power supply controls,and combined operation tools.These innovations allow for 4000 meter ROV flight,safe deployment,retrieval,and unmanned deep-sea scientific tasks,with some components even extendable to utilization in a 6000 meter platform.Eventually,the engineering product version of the complete ROV system was engineered by incorporating key self-made components such as hydraulic compensation propellers,control light boxes,tool valve boxes,and underwater electronic pods.The system is subject to component-level,subsystem-level,and complete system-level tests,coupled with the first sea trial,and a rigorous nine-day,eight-dive deep-sea ecological research mission,gathering abundant scientific samples and data,thereby effectively validating the operation capability and reliability of this complete ROV system.
