Abstract
A wind turbine includes a nacelle that houses a dynamo and a vane wheel coupled to an end of the dynamo. The nacelle is movably mounted to a post. The nacelle has a body forming a circumferentially extending curved slot that has a front portion forming a reducing section and a rear portion forming an expanding section. The vane wheel has a hub at a center thereof and including a plurality of blades radially extending therefrom. Each blade has an end forming a down wash. With the curved design of the nacelle body, the rising angle of airflow exiting the nacelle is improved and with the down wash, the occurrence of tip vortex is suppressed, whereby the utilization efficiency of wind energy in the wind generation operations is improved.
Claims7
A wind turbine, comprising:
- a nacelle, which comprises a nose and a body, the nacelle body forming a circumferentially extending curved slot, which comprises a front portion that forms a reducing section and a rear portion that forms an expanding section, a valley being defined between the reducing section and the expanding section;
- a dynamo, which is received in the nacelle and comprises shaft, which is rotatable to generate electrical power;
- and
- a vane wheel, which is coupled to the shaft and comprises a hub, the hub having a circumference from which a plurality blades radially extends, each blade having an end forming a down wash, the vane wheel and the shaft of the dynamo forming a driving coupling therebetween.
