Electric anti-icing heating device of composite material propeller blade

The invention discloses an electric anti-icing heating device of a composite material propeller blade. An inner rubber layer matched with a front edge boundary line on the surface of the front edge ofa blade body and containing grooves reserved in the two sides of the blade body is tightly bonded in the containing grooves. The glass cloth wrapped and tightly bonded with the electric heating filmis tightly bonded on the inner rubber layer; the outer rubber layer of which the edge is slightly greater than that of the accommodating groove is integrally and densely bonded outside the inner rubber layer, the glass cloth and the electric heating film; one end of the wire joint circular ring is connected with a binding post on the paddle rectifying disc; one end of the metal wire penetrates through a conductive metal sleeve wrapped in the T-shaped end of the wire connector, and the T-shaped end, the metal wire and the conductive metal sleeve are welded and fixed after being connected in a pressing mode.
