Abstract

The invention relates to a vertical axis wind turbine which is mainly used for wind power utilization. In existing vertical axis wind turbines, various kinds of structures for installing and supporting blades are complex and heavy, so that the wind power utilization efficiency and economical performance are affected, and the structures are not likely to be realized in large wind turbines. The vertical axis wind turbine comprises a tower, a motor, a blade mounting disk, cross beams, blades, outer inhaul cables, inner inhaul cables, a supporting rod and cross beam inhaul cables. The blade mounting and supporting structure is simplified through the inhaul cables, and the economical performance and the wind power utilization efficiency are improved.
