Title:
FAN BLADE STURCTURE AND WIND-DRIVEN DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/145044
Kind Code:
A1
Abstract:
A fan blade structure includes at least a fan blade (20, 20B), and the fan blade includes a frame (21, 21B), at least a unidirectional board (30, 30B) and a location-limited means. The unidirectional board is pivotally disposed on the frame, and the location-limited means is disposed between the frame and the unidirectional board for controlling opening or closing of the unidirectional board relative to the frame. A synchronous baffle (50, 50B, 50C) is disposed on the frame. When the unidirectional board is located on the windward position, the unidirectional board is closed upon the frame because of limiting of the location-limited means. When the unidirectional board is located on the leeward position, the unidirectional board can be synchronously opened by the synchronous baffle. And a generator (80) of a wind-driven device can be driven by the machinery energy which is generated while the fan blade structure is pushed by the wind. The fan blade structure of the invention can effectively improve utilization rate of wind energy and prevent the whole wind-driven device from being damaged by strong wind.
