为了实现海上电子围栏中红外对射装置的自供能,同时降低供电成本和简化安装,设计了一种基于固-液摩擦纳米发电机的海洋红外对射自供能发电胶囊。对摩擦纳米发电机发电胶囊(PC-TENG)进行仿真电学分析与0.02~2.00 Hz工况下的实验,验证了PC-TENG可以将波浪能转换为电能。仿真模拟的最大电势为3.2 V,基于去离子水的PC-TENG最大短路电流和开路电压分别为27.38μA和2.84 V。为了提高装置的实用性和输出性能,采用更接近海水的摩尔分数4%的氯化钠溶液作为液体摩擦材料进行对比实验,最大短路电流和开路电压分别为21.62μA和2.08 V,验证了使用海水作为液体摩擦材料的可行性。最后,进行了耐久性测试,基于去离子水的PC-TENG短路电流和开路电压分别衰减了5.5%~6%和3%~4%,基于摩尔分数4%的氯化钠溶液的PC-TENG短路电流和开路电压均衰减了6%~7%,验证了发电的耐久性,为海上电子围栏供能提供了新的参考和思路。

To realize self-powered of infrared intruder detection devices in marine electronic fence,reduce power supply cost and simplify installation,a marine infrared intruder detection self-powered power capsule based on solid-liquid triboelectric nano-generator was designed.The electrical analysis of the power capsule of triboelectric nano-generator(PC-TENG)was simulated and the experiment was carried out under the condition of 0.02-2.00 Hz,verifying that the PCTENG can convert wave energy into electric energy.The simulated maximum potential is 3.2 V,and the maximum short circuit current and open circuit voltage of the PC-TENG based on deionized water are 27.38μA and 2.84 V,respectively.To improve the practicability and output performances of the device,sodium chloride solution with a mole fraction of 4%closer to seawater was used as the liquid friction material for comparative experiments.The maximum short circuit current and open circuit voltage are 21.62μA and 2.08 V respectively,which verifies the feasibility of seawater as liquid friction material.Finally,durability tests were carried out.The short circuit current and open circuit voltage of the PC-TENG based on deionized water decrease by 5.5%-6%and 3%-4%respectively,and the short circuit current and open circuit voltage of the PC-TENG based on sodium chloride solution with a mole fraction of 4%decrease by 6%-7%,which verifies the durability of the power generation.It provides new reference and idea for the energy supply of maritime electronic fence.
