Multi-element combined wind power generation device capable of achieving intelligent control over expansion and shrinkage

Abstract

The invention provides a multi-element combined wind power generation device capable of achieving the intelligent control over expansion and shrinkage. The multi-element combined wind power generationdevice capable of achieving the intelligent control over expansion and shrinkage can capture any wind speed resources and achieve all-weather power generation and is characterized in that a sphericalwind wheel internally provided with a blade expansion structure which is composed of upper blade and lower blade connecting shafts, a lower slider, an intelligent expansion sensor, an upper slider, blade expansion push rod, slider pins and an intelligent shrinkage sensor. Because an intelligent expansion and shrinkage control blade structure controls blades to expand or shrink along the change ofthe wind speed, the multi-element combined wind power generation device capable of achieving the intelligent control over expansion and shrinkage is a unique global wind power generation technology which is not affected by wind speed, not limited by wind direction and not limited by regions in use.

Description

technical field [0001] The invention relates to an intelligently controlled tensioning and closing wind energy multi-element synthesis power generation device. Background technique [0002] At present, as the cleanest and most mature wind energy, it is difficult to connect to the grid, resulting in curtailment of wind power, especially the inability to effectively utilize various wind resources. If the speed of wind turbines is higher or lower than the rated speed, wind energy will not be able to be used; that is, wind power generation The blades of the machine stopped rotating and could not continue to generate electricity. The common problem of the existing vertical and horizontal wind turbines in the market is that the output power is low, and they cannot make full use of various wind speeds. Either the wind is too large to be used, or the wind is too small to be used, thus losing 80 % more than wind resources. Contents of the invention [0003] The purpose of the pre...

The common problem of existing vertical and horizontal wind turbines in the market is that the output power is low, and they cannot make full use of various wind speeds of different sizes. Either the wind is too large to be used, or the wind is too small to be used, thus losing 80 More than % wind resource
