HORIZONTAL-AXIS WIND DRIVEN GENERATOR PROVIDED WITH PADDLE-SHAPED BLADE AND DRUM-SHAPED EXTENDABLE WIND WHEEL

Document Type and Number:

WIPO Patent Application WO/2015/123924

Kind Code:

A1

Abstract:

A horizontal-axis wind driven generator comprises a tower (9), a fan main shaft (7), a generator (8), and a drum-shaped extendable wind wheel (20). The drum-shaped extendable wind wheel (20) comprises a paddle-shaped blade (4), a blade shaft (13), a front frame, a middle frame, a rear frame, an arc connection rod, and an adjustment apparatus. An inner frame (10) of the front frame, an inner frame (5) of the middle frame, and an inner frame of the rear frame are sequentially assembled on the front section of the fan main shaft (7). The inner frame (5) of the middle frame and the fan main shaft (7) are fixed in place using bolts. The front frame and the rear frame are slidably fitted to the fan main shaft (7). The paddle-shaped blade (4) is assembled on the middle frame. Slide blocks (15) on end portions of the paddle-shaped blade (4) are separately fitted to slideways (18) of the front frame and the rear frame. The adjustment apparatus drives the slide blocks (15) on the end portions of the paddle-shaped blade (4) to adjust the windward angle of the paddle-shaped blade (4). The horizontal-axis wind driven generator improves output power and the wind capture efficiency of a fan, and reduces unit cost of power generation and reduces repair and maintenance costs, so that the horizontal-axis wind driven generator has a wide application range of wind speeds.
