Design And Research Of Four-float Oscillating Flapping Wing Wave Energy Generation Device

As a new energy with high energy density,wide distribution,clean and renewable,wave energy has great potential and value for development and utilization.Single float wave energy power generation device has small unit capacity,high power generation cost,and cannot fully capture wave energy per unit area.In order to achieve efficient acquisition and stable power output of wave energy,a design scheme of a four-float oscillating flapping-wing wave power generation device with a float radius of 2.5 m is proposed on the basis of the research project of the National Natural Science Foundation of China "Research on adaptive acquisition mechanism and dynamic conversion characteristics of oscillating flapping-wing wave energy".Based on the principle of flapping-wing sinking and pitching,a four-float oscillating flapping-wing acquisition mechanism is created,and its structural parameters are optimized.Based on the multi-cavity hydraulic cylinder conversion system,a multi-cavity hydraulic cylinder conversion and merging system is created.Due to the unstable output of electric energy of the generator,it is impossible to store energy directly,thus creating an electric energy conversion and energy storage system of a four-float oscillating flapping wave power generation device.Determine the composition and working principle of the four-float oscillating flapping-wing wave power generation device,as well as the parameters of the acquisition mechanism,hydraulic conversion and merging system,electric energy conversion and energy storage system.Set up the acquisition mechanism of four-float oscillating flappingwing wave power generation device with AQWA and simulate the angular displacement response of its flapping-wing,using AMESim to build a simulation platform for four-float oscillating flapping wave power generation device,set up a test platform for simulating oscillating flapping-wing wave power generation device,and simulate regular waves for test and simulation research.The results show that the four-float oscillating flapping wing wave power generation system can work stably under the action of waves of the third and fourth levels,the average input power of the battery pack is 46.5 kW and 56.5 kW respectively,charging the battery pack with a total capacity of 300 Ah from 0% to 100% requires 1.42 hours and 1.17 hours,respectively;All performances of the test platform meet the requirements and can operate stably,the experiment verifies the rationality and feasibility of the power generation principle of the four-float oscillating flapping wing wave energy generator,and the research results lay a theoretical foundation for the development and research of array wave power generation device.
