An anti-
icing wind power blade, consisted of a wind
turbine blade, wherein the wind
turbine blade is provided with an anti-
icing heating device, and wherein the anti-
icing heating device consists of an
air heating system and an
electric heating system, wherein the two systems are independent from each other, without mutual interference, and heat the wind
turbine blade separately or simultaneously. The
air heating system and the
electric heating system are both located inside the wind
turbine blade, wherein the
air heating system comprises an air heating control cabinet and an air heating device, and the
electric heating system comprises an electric heating control cabinet and an electric
heating element, the wind
turbine blade is divided into a
front edge and a back edge by a
front edge web plate and a back edge web plate, wherein the air heating device is disposed in the back edge and the electric
heating element is disposed on the outer surface of the
front edge of the blade, and the air heating control cabinet and the electric heating control cabinet are disposed at the blade root. The current invention has an air
heating system and an electric
heating system. When the electric
heating system malfunctions, the air heating system can automatically start and heat. As a result, the usage does not need to be stopped during repair, and the usage efficiency is increased, and is more appropriate for use in severe environment.
