The invention discloses a wave energy power generation device which comprises an underwater floating body, an energy conversion unit installed in the underwater floating body and a center floating body fixed to the upper end of the underwater floating body, the outer wall of the center floating body is sleeved with a main floater, and the main floater is connected with the energy conversion unit through a pressure cylinder. At least two anchoring units are arranged on the peripheral side of the underwater floating body, a plurality of auxiliary floater units are symmetrically distributed on the peripheral side of the main floater, and the auxiliary floater units are in rigid connection with the main floater. The device has the advantages that the auxiliary floater units which are rigidly connected are arranged on the periphery of the main floater, the contact area between the device and the sea surface is increased through the auxiliary floater units, the overall water blocking effect of the device is enhanced, the freedom degree of the main floater in the five directions of swaying, surging, yawing, rolling and pitching can be effectively restrained, and the service life of the device is prolonged. The device can be autonomously maintained in an initial floating state and keep heaving single-degree-of-freedom wave energy capturing movement, and the capturing efficiency of the wave energy is improved.

    本发明公开一种波浪能发电装置,包括水下浮体、安装在水下浮体内部的能量转换单元,以及固定在水下浮体上端的中心浮体,中心浮体的外壁套设有主浮子,主浮子通过压力缸与能量转换单元连接,水下浮体的周侧至少设置有两组锚泊单元,主浮子的周侧对称分布有若干副浮子单元,且副浮子单元与主浮子为刚接。本发明的有益效果是:通过在主浮子的周侧设置圆周分布有刚接的若干副浮子单元,该副浮子单元增加了装置与海面之间的接触面积,增强装置整体的阻水效应,能够有效抑制主浮子在横荡、纵荡、艏摇、横摇和纵摇等五个方向的自由度,装置可自主维持在初始浮态,保持做垂荡单自由度的波浪能俘获运动,提高波浪能的俘获效率。
