Research On Wave Energy Power Generation Device Applied To Navigation Mark

This paper mainly studies the wave energy devices that provide energy for the navigation mark.The system is designed by the simulation results.To achieve the self-sufficiency of the beacon light energy.Firstly,this paper makes a related analysis of the advantages and disadvantages of the traditional navigational aid energy and the navigation aid energy commonly used at the present stage,and proposes the advantages of wave energy for the navigation aids.Then,it analyzes the deficiencies of the commonly used wave navigation aids technology at the present stage and combines them.The mature technology of wave energy generation at home and abroad will pave the way for the study of wave power generation devices in this paper.,and design of wave energy beacon at last.Second,The force analysis of the floater moving in the wave According to the potential flow theory,we solve the additional mass,additional damping and wave excitation force of the vibration buoy.Based on the force of the buoy,establish the boundary equation and the kinematic equation with energy output load,and solve the dynamic equation.Third,In the case of different wave periods,the added mass is solved by hydrodynamic calculation software WAMIT,and the resonance size of floating body and wave is obtained based on the resonance formula.,and then analyze the probability distribution of certain areas,draw different shapes floating body size parameters of resonance cycle.Fourth,the hydrodynamic performance and the motion response of the navigational device with different shape float are simulated.The main calculation method using hydrodynamic numerical simulation software WAMIT and the Runge Kutta analysis of floating body movement,added mass,the different shapes of the floating body damping,wave force,the influence trend and cycle,displacement,amplitude,average power conversion,conversion rate by cycle and hydraulic damping effect trend.To prepare for the type selection of the follow-up buoy floater.Finally,the design of wave energy navigation aids is designed.Based on the above conclusions,vertical cylindrical floater is selected as the buoy for navigation aids,and relevant parameter selection and design for hydraulic system,motor and so on are made.
