Indretning til maskinel rengøring af et vindkraftenergianlægs rotorblad under drift

摘要

The cleaning device (9) is automatically pressed into contact with the rotor blade (4) of the wind turbine rotor during rotation of the latter by the force of gravity or centrifugal forces, so that a cleaning element (14), e.g. a scraper (10), engages the rotor blade front edge (7), a guide (11) supporting the cleaning element over the length of the rotor blade. A flow element (13) may control the movement and/or application pressure of the cleaning element.
