摘要
海洋波浪能是一种清洁的海洋可再生能源,受到了广泛关注。设计和制作了一种摆臂浮子式波浪能实验装置,并在船模拖曳水池进行实验,以研究该装置的运动和能量转换性能。摆臂浮子式波浪能实验装置由两个浮子、两个摆臂以及机械传动装置和发电机组成,装置固定于拖车之上。通过水池实验测量不同工况下浮子的垂向运动加速度和发电机的输出电压,分析波高和周期对浮子运动的影响,计算装置在不同波浪条件下的能量转换效率。从实验结果可知,在波浪作用下,装置的垂荡运动性能较好,具有较高的能量转换效率。
Ocean wave energy is a clean marine renewable energy, which has received widespread attention. A wave energy device with swing arms and floaters was designed and produced. To study the movement and energy conversion performance of the device,model experiment was carried out in the tank. The device was composed of two floaters, two swing arms, mechanical transmission device and generators. The device was fixed on a trailer. Through experiments under different working conditions, the vertical acceleration of floaters and output voltage of the generator were measured. Finally, the influence of wave height and period on floaters＇ movement was analyzed, and the wave energy conversion efficiency was computed. Experimental results show that under action of the wave, the heaving motion performance is satisfactory, and the device has high energy conversion efficiency.
