Small Wave Power System Variable Angle Guiding Device And Its Performance Analysis

With the development of traditional energy, it is imminent in the deterioration of environment pollution and green energy problem. Wave is used as the most ideal and can be one of the most promising green energy. Improving the wave energy power generation device and the utilization efficiency of wave energy has been concerned by many countries.Using the wave energy power generation system and putting forward a kind of variable angle type wave power device to improve the utilization rate of wave energy on expanding the scope of wave velocity. Studying on the polymer flow and protecting the impeller overload performance under high velocity. Based on continuity equation and Bernoulli’s energy equation, considering the energy loss in the waves that flowing into the inside of the dome. It has flexible change of wave impact at high waves flow velocity.Based on the similar movement principle of turbine, selecting a impact impeller as variable angle core components in the dome with the working principle of the similarity principle. Determine some related parameters of the mechanical impeller and analyze the exercise of mechanical impeller forms. About the waves on the fluid flow in the impeller rotating impact area of the change of value, set up a relative velocity triangle. Analysis the impact current role on the impeller torque, moment of momentum in the impeller output relations is obtained.According to the impeller and the relationship between the wave velocity, analyzing the loss of energy in impeller device, and calculating the action of the wave power generation performance under the east of Chinese sea in level III. As the flow rate increasing, the impeller in conventional dome is under the condition with load operation. Variable angle dome impact the area of contraction, and get wave energy utilization along with the change of import flow.Finally establishing and selecting model from three aspects: the diversion ratio of mouth axle, the shape of dome, the initial point. Accumulation and analyzing some different shape domes in external effects wave, choose the initial opening angle and the most efficiency one, using some different of wave energy rate.
