The blade sweeping warning system of the vertical wind turbine comprises an ultrasonic sensor, a single chip microcomputer, a controller, an alarm device and the like, wherein the ultrasonic sensor is installed on the tower of the vertical wind power generator, and detects between the blade and the tower cylinder. The distance and output distance data signal; the single chip is used to receive the distance data signal output by the ultrasonic sensor and calculate the distance data value according to the distance data signal, and output the data value signal when the distance data value is less than the first early warning value.
The controller in the blade sweeping warning system of the vertical wind turbine receives the data value signal output by the single chip microcomputer and outputs a control signal; the alarm device is connected to the controller through the control line and receives the control signal to issue different alarm signals. The blade sweeping warning system can monitor the distance between the blade and the tower in real time and alarm in time to effectively avoid collision between the blade and the tower, thereby improving the safety of the wind turbine.
In addition to the blade sweeping warning system in the vertical wind turbine, lightning protection measures should be provided to shield, mechanically, hoist and zinc oxide electrical, overvoltage in the fan, transmission, electrical and electronic systems of the fan. Protectors, grounding devices, artificially reduce the damage caused by lightning strikes to an acceptable level.
