Rotor blade deicing device, wind energy plant and method for operating a rotor blade deicing device

摘要

The invention relates to a rotor blade deicing device, a wind energy plant (2) and method for operating a rotor blade deicing device. The wind energy plant (2) comprises a rotor (4), at whose rotor hub (6) at least one rotor blade (8) is rotatably mounted. A part of the rotor blade deicing device, in particular a fan (20) and / or a heating device (18), are fixedly connected to the rotor hub (6). The first and the second channel (22, 30) of the air-guiding system (16) are guided coaxially with one another in a connecting region and are stationary with the rotor hub (6) in a first section (46) and stationary with the rotor blade in a second section (52) (8) formed. The connection of the sections (46, 52) via a rotary feedthrough (40), which is constructed of two coaxial with each other out flexible hoses (60, 62).
