Vibration control device suitable for ocean buoy

The invention relates to the technical field of ocean engineering, and discloses a vibration control device suitable for an ocean buoy. The mass block is suspended in the floater shell, a cavity is formed in the mass block, and two conductive metal sheets are arranged on the bottom surface of the cavity; one end of each spring is connected with the mass block, and the other end of each spring is connected to the inner wall of the floater shell; the particle damping group comprises a plurality of damping particles, and the plurality of damping particles are all placed on the conductive metal sheet; the energy utilization end is electrically connected with the conductive metal sheet; when the damping particles move relatively on the conductive metal sheet, current is generated and conducted to the energy utilization end. The vibration suppression effect can be provided in multiple directions in the plane, the vibration suppression device is suitable for vibration suppression of the ocean buoy, the particle damp
