The invention discloses a self-guided multi-degree-of-freedom wave energy power generation device. The self-guided multi-degree-of-freedom wave energy power generation device comprises a support module and a power generation module; the support module is of a multi-box truss structure; the power generation module comprises a self-guided hydraulic PTO device and a magnetic induction power generation device; in the self-guided hydraulic PTO power generation device, two stand columns are driven by waves to pitch in different directions, and the stand columns swing back and forth to make a hydraulic generator generate power; and in the magnetic induction power generation device, double floats heave along the peripheries of the stand columns under the action of waves and drive magnetic rods toreciprocate up and down in the stand columns, and magnetic induction lines generated by the displacement of an electromagnetic field are cut by electromagnetic coils to generate electric energy. According to the self-guided multi-degree-of-freedom wave energy power generation device, a self-guided multi-degree-of-freedom wave energy capture system based on the combined motion of pitching and heaving is established, the defect that a traditional device only captures wave energy in one direction is overcome, the comprehensive utilization of wave energy in any direction is realized, and the waveenergy capture efficiency is greatly improved; and the self-guided multi-degree-of-freedom wave energy power generation device can be widely applied to existing marine engineering structures.
本发明公开了一种自导向式多自由度波浪能发电装置,包括支撑模块和发电模块;所述支撑模块采用多箱体桁架式结构;所述发电模块包括自导向液压PTO装置和磁感应发电装置;自导向液压PTO发电装置通过波浪带动两个立柱在不同方向产生纵摇,立柱往复摆动,使液压发电机发电;磁感应发电装置在波浪作用下双浮子沿立柱外周垂荡运动,带动磁棒在立柱内上下往复运动,电磁场发生位移产生的磁感线被电磁线圈切割而产生电能。本发明建立了基于纵摇和垂荡联合运动的自导向多自由度波浪能俘获系统,改变了传统装置仅俘获一个方向的波浪能缺点,实现了对任意方向波浪能的综合利用,大大提高了波浪能俘获效率;可广泛运用到现存的海洋工程结构中。
