Abstract

This paper proposes a vertical axis power generation device based on tidal energy for sensor used for information collection, the energy supply bottlenecks solving, and the sensor working efficiency improvement. The underwater operation test of the prototype system is carried out for finding the relation between the output power and the blade deflection angle and the blade speed ratio. This paper discusses how to improve the efficiency of energy conversion by modifying the parameters of prototype, which can provide a reliable guidance method for the next practical application. Experimental results show that the device can meet the energy demand of sensor networks.
