Design and research of energy supplement system for ocean buoy

Abstract

Aiming at the problem of energy supplements for ocean buoys, an energy supplement system for ocean buoys is designed. The buoy shakes under the action of waves, and the energy supplement system located in the buoy collects ocean kinetic energy and converts it into stable electric energy for buoy power supplement or storage. The working principle, design schemes, and structural composition of the ocean buoy energy supplement system are determined. According to the motion principle of the shaking pendulum, the system torque equation is established. AQWA is used to simulate the motion characteristics of the floater under the first level of regular and irregular waves, and the roll angle displacement of the floater is taken as the input of the simulation model. The joint simulation of Adams and AMESim is used to build the electromechanical coupling simulation model of the system, which verifies the rationality of the design scheme. The results show that 3.3 V and 1 A DC can be generated under the action of first-order regular wave and irregular wave, and stable power output can be achieved to supplement the buoy or charge the battery.
