Design and Research on Energy Saving Zero Speed Fixed Depth Control System of Underwater Operation Platform

介绍了一种节能型零速定深控制系统,可用于水下作业平台的水下定深悬停作业工况。该控制系统采用压缩空气辅助做功的“泵排自注”工作原理,通过对作业平台内部的专用液舱实施速度可控的自流注水和利用小功率排水泵进行排水,从而改变作业平台的水下重力和浮力平衡关系,实现其水下零速期间的深度稳定控制,并能实现节能和降噪目标。重点说明了该控制系统的工作原理、技术方案及陆上验证试验。

An energy-saving zero speed fixed depth control system is introduced. It can be used for underwater fixed depth hovering operation condition of underwater operation platform. The control system adopts the working principle of pump drainage and artesian water injection with compressed air assisted work. Through the implementation of artesian water injection with controllable speed for the special tank inside the operation platform and the use of low-power drainage pump for drainage,the balance relationship between underwater gravity and buoyancy of the operation platform changes. So,the zero speed depth stability control is realized for the operation platform during underwater,and the goals of energy saving and noise reduction can also be achieved. The working principle and technical scheme of the control system and the verification testing on land are highlighted.
