Title: OFFSHORE WIND TURBINE AND BLADE DAMAGE PREVENTION DEVICE AND METHOD
Abstract:
A blade damage prevention device (200) for a wind turbine, comprising: a pressure sensor (210) which is provided on the surface of a blade (100), being configured to capture the surface pressure applied to the blade (100); a signal analyzer (220) which is electrically connected to the pressure sensor (210), being configured to receive the surface pressure and when the surface pressure satisfies a preset condition, to generate a triggering signal; a controller (230) which is electrically connected to the signal analyzer (220), being configured to generate a vibration signal after receiving the triggering signal, the vibration signal comprising a vibration frequency; and a vibrator (240) which is provided in the blade (100), being electrically connected to the controller (230) and configured to generate vibrations at the vibration frequency according to the vibration signal. Further provided are a blade damage prevention method and an offshore wind turbine having the blade damage prevention device.
