The present invention relates to a variable windmill wing wind power generator having a power generation efficiency increasing means, which includes: an installation unit; a vertical rotating shaft; a bearing; '['-shaped holders; a plurality of inner wing installation units; support rods; a plurality of outer wing installation units; support rings; vertical support rods; support bars; a plurality of diagonal support bars connected between the upper and lower outer wing installation units within the same group; ladders; windmill wings; support units; a power generating means; a windmill wing fixing means; and a fixing means driving device. According to the present invention, the wind power generator can fold the windmill wings in the wind receiving direction and unfold the windmill wings when they are rotated by 180° from the wind receiving direction so as to minimize a resistance force exerted on a rotary force of a windmill shaft, thus increasing the power generation efficiency. The wind power generator according to the present invention can simplify the manufacturing process by the simple structure and be installed in a plural number in various places regardless of the installation location, thus maximizing the amount of power generation per unit area, achieving the industrial purpose, and generating electricity in the environment-friendly fashion without causing pollution such as greenhouse gas. Also, the wind power generator according to the present invention can be installed in strong as a group with up/down multi-stages, stop easily the rotation operation of the windmill wings according to need, and reach easily a troubleshooter at the position of corresponding windmill wing which needs to repair, thus performing a follow-up control of maintenance conveniently. |
