SMALL WIND POWERED GENERATOR

摘要

A small aero-generator is provided to prevent damage of rotary airfoil unit caused by an object which flows in because of strong wind. A small aero-generator comprises a body(10) wherein upper plate and lower plates with plural primary wind inlet ports and lateral plates with secondary wind inlet and outlet are formed; a support plate(20) which is fastened to the outer side of the lateral plate; plural wind concentrating member(30) which is hemispherical on the support plate; a rotary airfoil unit consisting of a rotary shaft and plural airfoils which are fastened to the rotary shaft; and a power generator(50) which converts the torque transmitted from the rotary shaft to the electric energy. The wind concentrating member is connected to plural primary or secondary wind inlet ports through the inlet tube. The rotary airfoil unit is installed inside the lateral plate. The power generator is connected to the rotary shaft.
