NOVELTY - The utility model claims a wind power generation blade de-icing system, comprising: a control cabinet one, a control cabinet two, a graphene heating film, a film and an air pump; the control cabinet I and the control cabinet II are installed on the blade root; the control cabinet I and the control cabinet II are independently arranged; the control cabinet I is electrically connected with the graphene heating film; the graphene heating film is distributed on the inner wall of the blade shell from the blade root to the blade tip in the length direction of the blade; forming a spiral line around the blade; the starting point of the line is the blade root position; the end point is the blade tip position; film is set on the tip part of the blade; the film and the blade form a cavity; the blade tip position is provided with at least one vent hole; the air pump is connected with the vent hole through the vent pipe; the cavity is ventilated, and the air pump is electrically connected with the control cabinet. The utility model can effectively prevent the blade surface from icing problem, ensure the wind generating set normally safe operation and normal power generation in the environment of easy icing.
