Manufacturing method of retractable fan blade with electric heating anti-icing function

The invention discloses a retractable fan blade with an electric heating anti-icing function, which belongs to the technical field of wind power generation. The invention includes a primary telescopic blade, a secondary telescopic blade, a main blade, an electric heating area, a thin-film solar cell, and a motor; Electric heating anti-icing; the first-level telescopic blades are slidably installed in the second-level telescopic blades, and the second-level telescopic blades are slidably installed in the main blades. The invention drives the first-level telescopic blade to slide in the inner cavity of the second-level telescopic blade through the electric motor, and drives the second-level telescopic blade to slide in the inner cavity of the main blade when it reaches a limited position, thereby changing the overall length of the blade to adapt to strong winds and protect against loads The larger blade tip is protected from damage. Protect the tip of the blade with a large load from damage. Protect the tip of the blade with a large load from damage.
