Abstract

The invention provides a horizontal-axis wind generating set with foldable wind wheels and a using method. The horizontal-axis wind generating set with the foldable wind wheels comprises an inner and outer double wind wheel and an annular cabin, wherein the inner and outer double wind wheel comprises an outer wind wheel and an inner wind wheel, and the outer wind wheel is mounted on the outer side of the annular cabin and is arranged in the manner of a foldable structure; the inner wind wheel is mounted on the inner side of the annular cabin; the annular cabin comprises a mechanical transmission system and a direct-driven generator, and the direct-driven generator is provided with rotors, and the axes are arranged in the vertical direction; and the inner and outer double wind wheel is in kinematic mechanical connection with the direct-driven generator, and wind energy is converted into electric energy. When the horizontal-axis wind generating set with the foldable wind wheels encounters extreme disastrous weather conditions, the outer wind wheel is folded, the wind wheel swept area is reduced, and safety of the wind generating set is protected. According to research and development of the device, the structural characteristics of the horizontal-axis wind generating set are fully utilized, components and the connection form are systematically optimized, the manufacturing and mounting cost is controlled, and meanwhile the capability of the horizontal-axis wind generating set for coping with disastrous weather conditions is effectively improved.

Description

technical field [0001] The invention relates to a wind rotor of a wind power generating set, in particular to a horizontal axis wind generating set of a foldable wind rotor and a use method thereof. Background technique [0002] As an important part of renewable energy, wind energy is an important scientific research direction for the green and healthy development of the human living environment in the new century how to use it efficiently. With the popularization of wind power generation, efficient wind power generation equipment and convenient power storage and transmission methods are all research hotspots in the industry. According to the characteristics of my country's regional resources, it is an important goal for the development of the renewable energy industry in the near future to vigorously develop offshore wind power, thereby affecting the composition and proportion of the energy structure of developed coastal cities. However, the situation in China's sea area i...
