Title:
FLAPPING TYPE WIND POWER GENERATOR
Document Type and Number:
Japanese Patent JP2012092728
Kind Code:
A
Abstract:

To provide a flapping type wind power generator that is prevented from falling into a mechanical equilibrium point (dead point) in a mechanical transmission part which surely reverses a pitch angle being an attack angle of blades against wind at an upper end position and a lower end position of flapping to thereby transmit flapping to a power generation part, and that is prevented from stopping the flapping operation as a result.

The flapping type wind power generator includes: as a pitch angle reversal keeping means, magnets which are attached to a blade base part and a blade tip part and repel each other or attract each other, and/or wind cups effectively reversing the blades at the upper end position of the blade flapping; and polar magnets which are arranged at a part of a transmission means and a part of a support means and repel each other as an avoiding means for operation stop of the flapping at the mechanical equilibrium point.
