ENERGY ACCUMULATION DEVICE IN EFFICIENT POWER GENERATION SYSTEM IN HORIZONTAL/VERTICAL TYPE WIND POWER GENERATION

摘要

PPROBLEM TO BE SOLVED: To provide a wind power generation device equipped with a device accumulating energy at a time of strong wind with a flat spring shape power spring of a simple structure added, considering an actual situation that globe warming progresses more and more and needs for resource saving and energy saving is getting larger recently and that wind power generation device has been developed from the past as a effective usage of natural energy but that stable output can not be easily obtained according to change of wind direction and wind power. PSOLUTION: The blade 1 rotates the plate shape power spring 3 for accumulating energy around a shaft 1 (9) in regular direction at a time of strong wind power and gradually winds up the same. When wind direction changes or wind power gets small, energy of power spring accumulated at a time of strong wind power is gradually discharged. Stable rotation speed is maintained with effect of flywheel 5 installed on a rear stage accompanied by. As a result, stable output effect can be maintained. PCOPYRIGHT: (C)2007,JPO&INPIT
