针对海洋监测潜标系统的供电需求,研发设计一种元器件少、结构简单、适用于潜标的水下波浪能俘获系统。相对于使用液压系统的波浪能发电装置,此系统具有工质环保的特点。该系统由液囊、主体、基础和能量传输4部分组成,工质采用水。在实验室造波水槽中对该系统的特性进行模型试验研究,发现该系统适合在长周期和大波高的波浪下工作,试验中功率最大工况为波高0.20 m,周期3.4 s,功率可达5.2 W,效率最大工况为波高0.08 m,周期3.1 s,效率可达25%,且系统的功率和效率会随液囊在水下深度的增大而快速下降。
Abstract
In order to meet the power supply needs of marine monitoring submersible systems, an underwater wave energy capture system with few components and a simple structure is developed and designed for use in submersible beacons, and the system is environmentally friendly in terms of the working mass compared to wave energy generation devices using hydraulic systems. The system consists of a liquid capsule, a main body, a foundation and an energy transfer system, using water as the working mass. The system was tested in a laboratory wave tank and found to be suitable for long periods and large wave heights, with a maximum power of 0.20 m, 3.4 s and 5.2 W and a maximum efficiency of 0.08 m, 3.1 s and 25%. The power and efficiency of the system decreases rapidly as the depth of the bladder increases, providing a reference for subsequent practical applications.
