Embodiment 1

[0030] This embodiment provides a flexible inflatable wind power generation blade. The flexible inflatable wind power generation blade includes: an outer layer of a flexible film and an inner layer of a variable-gauge spacer fabric, and the inner layer of the variable-gauge spacer fabric is stretched The shape presented in the straight state is the shape of a wind power generation blade, and the inner layer of the variable-gauge spacer fabric uses high-strength and easy-to-bend high-performance fibers as the spacer filaments during preparation, so that the prepared wind power generation blades are naturally The upper and lower layers of the fabric can be in a bonded state; the outer layer of the flexible film is formed by coating the outer surface of the variable-gauge spacer fabric with a resin that has both sealing and adhesive properties, and an inflation port is reserved during coating.

[0031] Such as Figure 1 to Figure 4 As shown, the flexible inflatable wind power bla...

Abstract

The invention discloses a flexible inflatable wind power generation blade and a preparation method thereof, belonging to the technical field of wind power generation. The flexible inflatable wind power generation blade includes: a flexible membrane outer layer and a variable-gauge spacer fabric inner layer, the outer shape of the variable-gauge spacer fabric inner layer is the shape of a wind power generation blade, and the flexible membrane outer layer is connected to the variable-gauge spacer fabric. The variable-gauge spacer fabric is bonded to form a flexible inflatable wind power generation blade. The flexible inflatable wind power generation blade can be curled arbitrarily before inflating, which is convenient for transportation. With a certain shape and rigidity, it completely replaces the existing wind power blades made of hard materials. Therefore, the flexible inflatable wind power blade has the advantages of energy saving, high efficiency, convenient operation, strong applicability, and is conducive to the transportation and loading and unloading of wind power blades.

Description

technical field [0001] The invention relates to a flexible inflatable wind power generation blade and a preparation method thereof, belonging to the technical field of wind power generation. Background technique [0002] As a clean renewable energy, wind energy contains huge energy, and the global wind energy resources can be developed as a clean renewable energy; at the same time, clean renewable wind energy has attracted more and more attention from 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 prospect of wind power generation in the future will be better and better. Traditional wind power blades are all made of hard materials, which are large in size and heavy in weight; although there are already lightweight wind power blades made of fabric composite resin, the wind power blades are still made of hard materials, which are bulky and difficult to transport. Difficult to assembl...
