A horizontal axis wind generator set with a foldable wind rotor and a method of using the same

Abstract

The present invention provides a foldable wind rotor horizontal axis wind power generator set and its use method. The foldable wind rotor horizontal axis wind power generator set includes inner and outer double wind rotors and an annular nacelle, wherein the inner and outer double wind turbines The wheel includes an outer wind wheel and an inner wind wheel, the outer wind wheel is installed on the outside of the annular nacelle, and is arranged in a foldable structure; the inner wind wheel is installed on the inner side of the annular nacelle; the annular nacelle includes a mechanical transmission system . A direct-drive generator, wherein the rotor axis of the direct-drive generator is arranged along the vertical direction; the inner and outer double wind wheels are kinematically connected to the direct-drive generator to convert wind energy into electrical energy. When the horizontal-axis wind turbine generator set of the foldable wind rotor encounters extreme disastrous weather conditions, the outer wind rotor is folded to reduce the swept area of ​​the wind rotor and protect the safety of the wind turbine generator set. The research and development of this device makes full use of the structural characteristics of the horizontal axis wind turbine, systematically optimizes the components and connection forms, and effectively improves the ability of the horizontal axis wind turbine to cope with disastrous weather conditions while controlling the cost of manufacturing and installation.

Description

technical field [0001] The invention relates to a wind turbine of a wind turbine, in particular to a horizontal axis wind turbine of a foldable wind turbine and a method of using the same. Background technique [0002] As an important part of renewable energy, how to use wind energy efficiently is an important scientific research direction for the green and healthy development of human living environment in the new century. With the popularity 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, vigorously developing offshore wind power, thereby affecting the composition and proportion of energy structure in developed coastal cities, is an important goal for the development of the renewable energy industry in the recent period. However, the situation in China's waters is different from that in Eu...

Problems solved by technology

However, the self-weight of large-scale wind turbines can reach hundreds of tons or even thousands of tons, and a single component can also weigh more than ten tons or even tens of tons. The actuation system that can control its attitude change is itself a design problem. The overall center of gravity has shifted, requiring an update to its foundation design, and the construction cost has increased significantly
