Design and Study of Multi-Source Energy Harvester for Bird Repelling in Transmission Towers
Birds nest,roost or fly on transmission towers,which can lead to contact with transmission equipment,increasing the risk of short circuits,fires and power outages.In order to solve the problems of single power supply mode and poor reliability of bird repelling devices,a multi-source energy harvester was designed,and the triboelectric nanogenerator and solar cell were integrated.The triboelectric nanogenerator with double-layer friction structure was used to improve the utilization rate of wind energy,and the solar cell was combined to realize the collection of wind and light energy on the transmission tower.The experiment result shows that the peak power of the outer power generation structure is 4 500 μW,the peak power of the inner power generation structure is 400 μW,and the double-layer friction structure improves the power generation efficiency by nearly 10％.The maximum open circuit voltage of the solar cell is 11.2 V and the maximum short circuit current is 40 mA at the light intensity of 20 W/dm2 of xenon lamp.At the same time,a dual-channel power management circuit is designed based on the LTC3588 chip,and the energy collected by the the triboelectric nanogenerator and solar cell is stored and managed to provide stable 3.3 V voltage for electrical equipment.The multi-source energy harvester is used to drive the calculator and buzzer,which provides a new idea for the power supply and sensing system of bird repelling.
