A new eccentric vane tidal power generation device is designed. Firstly, the basic component of the device is briefly introduced. Secondly, the size of each part of the blades is determined. Thirdly, the structure de- sign of the tidal power generation device is completed. Finally, the working process of device is explained. Hydro- dynamic model of the blades of tidal power generation device is established, and computer simulation are obtained using fluid dynamics analysis by ANSYS software. According to the theory of fluid dynamics, mechanical design knowledge and the results of ANSYS simulation, the power and power factor of device are computed. Through theo- retical derivation, the power and power factor of the power generation device are calculated in the flow speed of 2, 3,5,7 m/s. The results show that the power factor is the highest when incoming flow velocity reaches 5 m/s.
