Wind power generator for street light

Abstract

The present invention relates to a wind power generator for street light comprising: a post member installed vertically; a central fixed shaft member installed horizontally on an upper portion of the post member; a first blade member rotatably installed around the central fixed shaft member and including a first blade rotated by wind on one side thereof; a second blade member rotatably installed around the first blade member and including a second blade rotated by wind on one side thereof; a cone member having an inclined shape at a specific angle so that wind smoothly moves toward the first blade member and the second blade member, and a power generation module rotated by the first blade member and the second blade member to generate power. According to the present invention, the first blade member and the second blade member can supply sufficient torque required for the rotation of the power generation module and can increase power generation time by driving the power generation module with the double blades. In addition, it is possible to minimize the installation space and reduce the size of the wind power generator by installing the first rotating shaft and the second rotating shaft in a double layer structure.
