Large-wind sail vertical rotation type wind power generation tower

Abstract

The invention relates to a large-wind sail vertical rotation type wind power generation tower, and solves the problems of the existing wind driven generator, such as difficult effective matching between wind wheels and a generator and low wind wheel power. The large-wind sail vertical rotation type wind power generation tower comprises impellers composed of an upright shaft and a wind sail blade,and wind control shells arranged outside the impellers. The large-wind sail vertical rotation type wind power generation tower is characterized in that multiple impellers and wind control shells are arranged and are mounted in multiple frames respectively and installed together vertically; the upright shafts of all impellers are connected with each other; and the upright shaft of the downmost impeller is connected with the main shaft of a variable-power generator, thus forming the large-wind sail vertical rotation type wind power generation tower. The invention has the advantages that as the variable-power generator is connected with the upright shafts of the impellers, the problem of difficult effective matching between the generator and the impellers is solved, and the impellers can be matched with the generator under any wind force, thereby reducing dependence on wind and improving the wind wheel power and the generating efficiency.

Description

technical field [0001] The invention belongs to a wind power generating device, in particular to a large sail vertical spinning wind power generating tower. Background technique [0002] At present, the world's energy resources are increasingly tense, and wind energy, as a clean energy source, has attracted more and more attention. Existing wind power generators are mainly composed of wind rotors, tower barrels and generators. The wind wheel is composed of three or more blades, the blades are fixed on the hub disk, and the hub disk is installed on the tower barrel. Due to the small wind-receiving area of ​​the blades of this kind of wind rotor, each blade is very long and has a large volume, so the tower barrel is very high. The tower barrel of a high-power wind turbine is even as high as more than 100 meters, with a diameter of several meters. , and the tower barrel is rotating, requiring a giant bearing with a diameter of several meters to support it. The problems that ...
