Abstract

The invention discloses a wind turbine generator capable of resisting strong wind. The wind turbine generator is characterized in that a fan impeller and a tower frame are specially designed, so that the performance of the wind turbine generator of still normally working in the strong wind environment is guaranteed. The wind turbine generator comprises an impeller, a hub, a machine room and a tower frame; the impeller is installed on the side surface of the hub; one end surface of the hub is connected with one side surface of the machine room; the top end of the tower frame is connected with the bottom surface of the machine room; the impeller is provided with an impeller mounting seat, an impeller connecting hole and impeller mounting seat holes; and the hub is in a triangular cone shape and is provided with a hub mounting flange and hub impeller mounting holes. As the impeller is installed at a certain inclination, larger bending stress cannot be applied to the impeller when the wind power is too large, and thus the action of resisting the strong wind is reached. The designed wind turbine generator realizes the effect of still working in the strong wind environment, has the characteristics of high power generation efficiency, good stability, long service life and the like and is suitable for practical application and popularization.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generator capable of resisting strong winds. Background technique [0002] During the operation of the wind turbine, when the wind speed exceeds the cut-out wind speed of the wind turbine, the bending stress on the blades of the wind turbine will reach the limit state. At the same time, the high wind speed will cause the internal gears of the wind turbine gearbox to run too fast. If the wind turbine keeps running at an overspeed for a long time, the heat in the gearbox cannot be dissipated in time, which will cause the gears in the gearbox to glue together. The alternator of the generator will also burn out due to prolonged overloading. Therefore, in order to protect the wind turbine from damage, the feathering brake of the wind turbine is required to stop the wind turbine at a high wind speed to achieve the purpose of protecting the wind turbine, whic...
