Abstract

A wind electricity generator with dwindled then widened spout comprises tower base, blower fixed on the top of the base and a dynamo drove by the blower. The blower is coaxially fixed to the spout in the dwindled part. The inlet area A1 of the spout is relative large, and along the wind direction, the area of laryngeal part A2 is the smallest, after the laryngeal, the area is enlarged to outlet area A3. With dwindled design, the wind speed is accelerated, so maximizing the utility of wind, decrease the blower's size and lowing down the cost.

Description

Technical field: [0001] The invention relates to a wind power generation device, in particular to a wind power generation device with scaling type energy collection and speed-up. technical background [0002] Wind energy is the fastest-growing clean energy among renewable energy sources, and it is also the most promising power generation method for large-scale development and commercialization. During the 10 years from 1993 to 2003, the annual growth rate of wind power generation in the world reached 29.7%. By the end of 2003, the global installed capacity of wind power reached 40.3 million kilowatts, and wind power generation accounted for 0.5% of the world's total electricity. Among them, the total installed capacity in Europe is 28.71 million kilowatts, accounting for 73% of the world's installed wind power capacity. In 2003, the cumulative installed capacity of wind power in Germany reached 14.61 million kilowatts, accounting for more than 1 / 3 of the world's total. In...
