Abstract

The invention discloses a double-blade vertical-axis wind power generation device and its working method. , the main support frame, and the auxiliary support frame; the main shaft blade and the auxiliary shaft blade rotate under the wind force. During the rotation, the gear transmission box increases its rotation speed, thereby prompting the generator to generate electricity; the electromagnetic brake generates electricity When the generator speed is too high, electromagnetic braking is performed on the generator to reduce the generator speed. The double-blade vertical-axis wind power generation device of the present invention utilizes the performance of wind energy to generate electricity, effectively utilizes new energy, adopts a vertical structure, and can generate electricity under light wind conditions, and the double-blade structure effectively improves power generation efficiency.

Description

technical field [0001] The invention belongs to the field of wind energy application, and in particular relates to a double blade vertical axis wind power generation device. Background technique [0002] Wind is a new energy source with great potential. People may remember that in the early eighteenth century, a violent gale swept across Britain and France, destroying 400 wind mills, 800 houses, 100 churches, 4 More than 100 sailboats were injured, thousands of people were injured, and 250,000 trees were uprooted. As far as the tree pulling is concerned, the wind generates 10 million horsepower (7.5 million kilowatts) in a few seconds. It has been estimated that there are about 10 billion kilowatts of wind power resources available on the earth for power generation, which is almost 10 times that of hydropower generation in the world today. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a yea...
