Abstract

Aiming at the efficient and safe utilization of wave energy and the protection of marine ecological environment, a new type of vertical oscillation wave energy generation device is designed. As a shallow water fixed device, the device is arranged at a depth of 40 meters near the shore. The buoy with the shape of water hyacinth heaves under the action of waves. The collected reciprocating linear kinetic energy is converted into rotational kinetic energy through the rack and pinion transmission mechanism inside the device, and then converted into stable electric energy through the electric energy conversion system to realize, so as to realize the conversion process from wave energy to electric energy, so as to make efficient and safe use of wave energy. The working principle of oscillating buoy wave energy generation device is analyzed and its structure is designed. Based on the motion characteristics of the float, the mathematical model of the system is established. The AQWA software is used to simulate the motion response of the float under the action of four regular waves, and the simulation results are used as input for subsequent joint simulation. Recurdyn software and AMEsim software are used to build a joint simulation model of electromechanical system to verify the design scheme. The results show that under the action of four-level regular waves, each system of the power generation device can work stably. The average power captured is 2.5 kW, and the total capacity of 150 Ah battery pack takes 48 minutes to fill.
