Technical field
The utility model relates to a kind of unsteady flow guide type vertical axis aerogenerator, relates in particular to a kind of blade and possesses turning power, and be applied to the unsteady flow guide type vertical axis aerogenerator of vertical axis aerogenerator.
Background technique
Existing wind-driven generator is according to the structural design difference of holding axle, can be divided into horizontal axis wind-driven generator (Horizontal Axis Wind Turbine, HAWT) with vertical axis aerogenerator (Vertical Axis Wind Turbine, VAWT).The main shaft of horizontal axis wind-driven generator is parallel with wind direction, and the main shaft of vertical axis aerogenerator is then vertical with wind direction.
The advantage of existing horizontal axis wind-driven generator is that generating efficiency is higher, therefore most commercial use and as the large-scale wind driven generator of coastal area, Taiwan all be the employing horizontal axis wind-driven generator.But, because the fan structure of horizontal axis wind-driven generator must could turn round towards the wind direction source, pursue the wind direction source so need to rely on installing wind-guiding empennage, also because so, blade need constantly be adjusted the position along with wind direction, causes horizontal axis wind-driven generator to be vulnerable to the influence of landform and atural object.
In comparison, existing vertical axis aerogenerator need not to adjust direction along with change of the wind, and various wind directions all can turn round, and the condition restriction of therefore installing environment is less.Existing vertical axis aerogenerator mainly adopts the Savonius rotors (Savonius) of S type blade, and the active force that produces on blade with the wind by wind-force impels blade rotation greater than the principle of the active force that produces on the contrary wind blade.Yet because against the wind blade can produce resistance to the rotation of blade with the wind, so rotating speed is relatively slow, generating efficiency is lower.
Existing technology has following shortcoming:
1. existing horizontal axis wind-driven generator, blade need constantly be adjusted the position along with wind direction, therefore is vulnerable to the influence of landform and atural object;
2. existing vertical axis aerogenerator, because blade can produce resistance to the rotation of blade with the wind against the wind, so rotating speed is relatively slow, generating efficiency is lower.
