摘　　要：针对海上浮标、领航灯等远海设施供电难的问题,设计了一种新的摆式波浪发电装置。为提高装置的可靠性和寿命,采用封装在箱体内与海水完全隔离的设计方案。创建了机械式能量转换装置以简化波浪能转换器并提高波浪能利用效率。详细叙述了摆式波浪能发电装置的设计方案,并建立了摆锤的数学模型以及结合线性波动中二维深水进行波理论计算,计算了装置的整机理论效率,同时对关键零件的疲劳寿命进行了分析和预测。实验结果表明,当箱体晃动周期为3 s、倾角为15°时,波浪发电机的平均输出功率为10 W左右,输出电压为14 V。研究证明,该波浪能发电装置的设计是可行的。Aiming at solving the power supply of offshore electrical facilities, a novel pendulum wave energy converter was proposed. The converter was sealed in a box and isolated entirely from sea water to obtain high reliability and long life. In order to improve the efficiency of the converter and simplify the whole system, a mechanical power transmission system was developed. The converter design was introduced in detail, and the mathematic model of the pendulum motion was established, as well as the theoretical efficiency of the converter was calculated, which combined two-dimensional deep-water linear-wave fluctuation theory, meanwhile the key part＇s fatigue life was analyzed and predicted. The experiment results show that, when wave period is 3 s, and the tilt angle of the converter box is 15° , the average power output of the converter is about 10 W, and the voltage can reach 14 V. The research proves that the wave energy converter design is feasible.
