针对波浪能高效安全利用以及海洋生态环境保护问题,设计一种新型垂直振荡波浪能发电装置。该装置作为一种浅水固定式装置,布置在近岸40 m水深处。仿水葫芦外形的浮子在波浪的作用下进行垂荡运动,采集的往复直线动能通过装置内部的齿轮齿条传动机构转换为旋转动能,再通过电能转换系统将其转换成稳定的电能,实现从波浪能到电能的转换过程,做到波浪能高效安全的利用。分析振荡浮子式波浪能发电装置的工作原理并进行结构设计。基于浮子的运动特性,建立系统内部的数学模型。运用AQWA软件模拟浮子在四级规则波作用下的运动响应,将仿真结果作为输入进行后续联合仿真。运用Recurdyn软件与AMEsim软件搭建机电系统联合仿真模型,对设计方案进行验证。结果表明：在四级规则波浪作用下,发电装置各系统能稳定工作,捕获的平均功率为9.5 kW,充满1组总容量为150 Ah的蓄电池需要48 min。
Abstract
Aiming at the efficient and safe utilization of wave energy and the protection of marine ecological environment, a new type of vertical oscillation wave energy generation device is designed. As a shallow water fixed device, the device is arranged at a depth of 40 meters near the shore. The buoy with the shape of water hyacinth heaves under the action of waves. The collected reciprocating linear kinetic energy is converted into rotational kinetic energy through the rack and pinion transmission mechanism inside the device, and then converted into stable electric energy through the electric energy conversion system to realize, so as to realize the conversion process from wave energy to electric energy, so as to make efficient and safe use of wave energy. The working principle of oscillating buoy wave energy generation device is analyzed and its structure is designed. Based on the motion characteristics of the float, the mathematical model of the system is established. The AQWA software is used to simulate the motion response of the float under the action of four regular waves, and the simulation results are used as input for subsequent joint simulation. Recurdyn software and AMEsim software are used to build a joint simulation model of electromechanical system to verify the design scheme. The results show that under the action of four-level regular waves, each system of the power generation device can work stably. The average power captured is 2.5 kW, and the total capacity of 150 Ah battery pack takes 48 minutes to fill.
