摘　　要：点吸收式波浪能发电装置安装成本高、生存能力差,设计了伸缩卷索式双浮体波浪能发电装置。该装置上下浮体由伸缩卷索连接,将浮体间的多个自由度相对运动转化为电能。装置安装时不需要海底施工,同时浮体的分舱设计可以提高装置的海上生存能力和可靠性。考虑到我国部分海域的波浪特征,制作了比例尺为1∶16的模型样机,并在武汉理工大学双试验段综合性水槽进行试验。分析结果发现:在波浪周期为1.0 s、外接电阻为125Ω时,装置的发电效率最大为12.49%。试验结果可为点吸收式波浪能发电装置的设计制造提供一定参考。Due to the problems of high cost of installation and poor survivability of the traditional point absorber, a two-body floating point absorber with retractable power take-off is proposed in this paper. The upper and lower floating bodies of the device are connected by retractable cable, which can convert the relative motions of multiple degrees of freedom between the floating bodies into electricity. Subsea construction are not required during installation of the device,and the subdivision design of the floating body improves the survivability and reliability. Considering the characteristics of waves in China, a 1∶16 model was constructed and tested in a comprehensive wave flume at Wuhan University of Technology. The analysis results show that efficiency of device is up to 12.49% in wave of period 1.0 s and external resistance of 125 Ω. The experimental results confirm the feasibility of new device and provide some guidelines for the development of point absorbers.
