Title:
BLADE STRUCTURE AND WIND DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/145065
Kind Code:
A1
Abstract:
A blade structure comprises at least a blade (20, 20B, 20C) having a frame (21, 21B, 21C), at least a one-way cover plate (30, 30B, 30C) and a limit mechanism. The one-way cover plate (30, 30B, 30C) is pivotally disposed on the frame (21, 21B, 21C), and the limit mechanism is disposed between the frame (21, 21B, 21C) and the one-way cover plate (30, 30B, 30C) for controlling the one-way cover plate (30, 30B, 30C) to be opened or closed relative to the frame (21, 21B, 21C). A synchronous baffle (50, 50B, 50C, 50D, 50E) is disposed on the frame (21, 21B, 21C). When the one-way cover plate (30, 30B, 30C) is located on the windward position, the one-way cover plate (30, 30B, 30C) is closed upon the frame (21, 21B, 21C) because of the limitation of the limit mechanism. When the one-way cover plate (30, 30B, 30C) is located on the non-windward position, the one-way cover plate (30, 30B, 30C) can be synchronously opened by the synchronous baffle (50, 50B, 50C, 50D, 50E). A wind driving device is also provided. The blade structure is pushed by wind power to generate mechanical energy which can drive a power generator (80) of the wind driving device. The blade structure can effectively improve the utilization of wind energy and protect the whole wind driving device from being damaged by strong wind.
