Abstract

This invention provides a vertical axis wind turbine which comprises a support set disposed on the ground and having a support pole, a rotation set disposed on the support set and having a spiral disc and a plurality of blade sets, a resilient set disposed on the rotation set and linked with the blade sets, and a frame pivoted with the top of the support pole, which can sustain the driving force of wind to drive the rotation of the rotation set and the support pole when the blade sets on the spiral disc are opened, thereby using the wind power to push the support pole and drive a gear member and the corresponding power conversion set for converting the wind power into mechanical power; when the wind is too strong or the rotary speed of the rotation set is too fast, the support set rotatably and downwardly drives the resilient set, such that the blade sets are moved downward by the resilient set and closed, during which the closed blade sets sustain the minimal wind driving force and accordingly minimal rotary speed, thereby protecting the wind power device from bearing an excessive wind force which causes wear and tear or damage.
