Flexible inflatable type wind turbine blade and manufacturing method thereof

Abstract

The invention discloses a flexible inflatable type wind turbine blade and a manufacturing method thereof, which belong to the technical field of wind power generation. The flexible inflatable type wind turbine blade comprises a flexible film outer layer and a variable-clearance spacer fabric inner layer, wherein the outer shape of the variable-clearance spacer fabric inner layer is the shape of the wind turbine blade; the flexible film outer layer and the variable-clearance spacer fabric inner layer are bonded to form the flexible inflatable type wind turbine blade; before being inflated, theflexible inflatable type wind turbine blade can be curled freely, and is conveniently transported; and after being inflated, the wind turbine blade has certain shape and rigidity in the presence of spacer filaments or spacer yarns, and an existing wind turbine blade of a hard material can be completely replaced, so that the flexible inflatable type wind turbine blade has the advantages of being energy-saving, efficient, convenient in operation, strong in applicability, and beneficial for transportation, loading and unloading of the wind turbine blade.

Description

Technical field [0001] The invention relates to a flexible inflatable wind power generation blade and a preparation method thereof, and belongs to the technical field of wind power generation. Background technique [0002] Wind energy, as a clean renewable energy source, contains huge amounts of energy. Global wind energy resources can be developed as a clean renewable energy source. At the same time, clean renewable wind energy is increasingly being valued by countries all over the world. With the development of the world economy, the wind energy market has also developed rapidly; there is no doubt that the prospects for wind power generation in the future will get better and better. Traditional wind power blades are made of hard materials, large in size and heavy in mass; although there are already lightweight wind power blades made of fabric composite resin, the wind power blades are still hard materials, which are bulky and difficult to transport. Difficulty in disassembly a...
