摘　　要：提出并设计了一种基于冲击式空气透平的波浪能摩擦纳米发电机,将其应用于振荡水柱波浪能转换装置中,能够将低频的海洋波浪能高效转换为电能。详细阐述了该发电机的结构与工作原理,搭建了两个实验平台,分别进行了电极参数优化实验和电学输出性能实验。实验结果表明,利用聚四氟乙烯作为电极的介电材料,其电学输出性能最优,聚四氟乙烯的厚度越大,电学性能输出越好。当发电机电极角度逐渐减小时,短路电流呈上升趋势。设计并制造了冲击式波浪能摩擦纳米发电机,进行了单风向半物理仿真实验。研究了不同风速下的电学输出性能,并进行了电容充电实验。通过电路设计驱动点亮了33盏LED。验证了冲击式波浪能摩擦纳米发电机的可靠性以及对小型传感器供能的潜力。An impulse air turbine based wave energy triboelectric nanogenerator(impulse wave energy TENG,IW-TENG)is proposed and designed to be applied in an oscillating water column wave energy conversion device,which can efficiently convert low frequency ocean wave energy into electrical energy.The structure and working principle of IW-TENG were elaborated,and two experimental platforms were built to carry out electrode parameter optimization experiments and electrical output performance experiments respectively.The experimental results indicate that using PTFE as the dielectric material of the electrode,the electrical output performance is optimal,and the larger the thickness of PTFE,the better the electrical output performance.When the electrode angle of the generator gradually decreases,the short-circuit current tends to rise.IW-TENG was designed and manufactured to conduct a single-wind direction semi-physical simulation experiment to study the electrical output performance under different wind speeds and conduct a capacitor charging experiment.The circuit design was driven to light up 33 LEDs.The reliability of IW-TENG and its potential to supply energy to small sensors are verified.
