The invention relates to the field of renewable energy power generation, and discloses a low-frequency and frequency-adjustable float-type wave power generation device. The low-frequency and frequency-adjustable float-type wave power generation device comprises a dual-mass vibrator device, wherein the dual-mass vibrator device comprises a first mass body, a second mass body, a connecting rod, a rotating shaft, a coupling and a generator; the generator is connected with the rotating shaft through the coupling; the connecting rod perpendicular to the rotating shaft is arranged on the rotating shaft in a penetrating manner; the two ends of the connecting rod are movably connected with the first mass body and the second mass body respectively; and the distances between the first mass body andthe rotating shaft and between the second mass body and the rotating shaft can be adjusted. The low-frequency and frequency-adjustable float-type wave power generation device adopts a dual-mass vibrator form, so that the required structural space is also obviously reduced while extremely low-frequency self-vibration is realized; a frequency tuning factor is considered, and the relative positions of the two mass bodies can be adjusted in real time to realize frequency modulation, so that resonance is realized and the output power is further improved; and the low-frequency and frequency-adjustable float-type wave power generation device has important application prospects in the aspects of maritime systems, new energy power supply and the like. 本发明涉及可再生能源发电领域，公开了一种低频且频率可调的浮子式波浪发电装置，包括双质量振子装置，包括第一质量体、第二质量体、连接杆、旋转轴、联轴器以及发电机，其中，所述发电机通过联轴器连接所述旋转轴，所述旋转轴上贯穿设有与之垂直的所述连接杆，所述连接杆的两端分别活动连接有所述第一质量体和第二质量体，所述第一质量体、第二质量体与所述旋转轴之间的距离均可以调节。本发明采用双质量振子形式，实现极低频自振的同时还显著缩小了所需的结构空间；并考虑了频率调谐因素，能通过实时调节两个质量体的相对位置以调频，实现共振进而提高输出功率；本装置在海事系统及新能源供电等方面具有重要的应用前景。
