Vertical axis wind turbine

The utility model discloses a vertical axis wind driven generator, which relates to the technical field of wind driven generators, and comprises a control tower, a generator and a rotary vane mechanism, the rotary vane mechanism comprises a lower baffle plate, an upper baffle plate and blades, and can prevent wind from being discharged from the upper and lower ends of the blades, so that the wind can better push the rotary vane mechanism to rotate, and the utilization efficiency of wind energy is improved; besides, the wind meter feeds back the detected wind speed, wind direction and other information to the Internet of Things control equipment, so that background workers can know the current working condition of wind power generation in real time, the posture of the fan can be remotely controlled in real time, and the motor is controlled to drive the wind guide pipe to rotate through the wind direction information detected by the wind meter; and a pipe opening, located at the outer end of the air cavity, of
