Abstract

The invention relates to vertical type blades for wind power generation. An assembly board disposed separately is formed on a blade frame, and a blade main body is pivoted between two separate assembly boards. Furthermore, a stopping piece is provided between the assembly boards and the blade main bodies, and the stopping piece is disposed on a leeward side of the assembly board relatively to the blade main body. Thereby the blade main body pivoted on the blade frame can transform its state of opening or closing according to the wind orientation for the windward side or leeward side of the blade frame. When wind blows to the windward side, the blade main body will be blocked by the stopping piece to be positioned and be in the state of closing such that wind power can be completely received by the blade and the blade can be pushed accordingly. When wind blows to the leeward side, the blade main body is in the state of opining to avoid bearing the resistance generated by wind power. Accordingly, it can efficiently prevent wind power from effecting on the windward side and the leeward side simultaneously to cause thrust offset, so as to significantly improve the efficiency of wind power generation.
