Embodiment 1

[0057] Embodiment 1: Strengthen the airfoil inflatable skeleton structure blade (as shown in Figure 2)

[0058] The reinforced airfoil inflatable skeleton structure blades have the same basic structure as the symmetrical airfoil inflatable skeleton structure blades shown in Figure 1, and their inflatable skeleton structures 1 are all formed by bonding or welding the inflatable skeletons, and can be made symmetrical Airfoil inflatable skeleton structure blades, and asymmetric airfoil inflatable skeleton structure blades; can be made into rigid inflatable skeleton structure blades, and can also be made into flexible inflatable skeleton structure blades; the difference is that to strengthen the inflatable skeleton structure Connection strength, between the two inflatable skeletons, add a double-arc-shaped reinforcing bracket 8 to increase the bonding or welding area between the inflatable skeletons, and strengthen the mechanical strength of the inflatable skeleton structure 1 . O...

Embodiment 2

[0060] Embodiment 2: Ray airfoil inflatable skeleton structure blade (as shown in Figure 3)

[0061] The ray airfoil inflatable skeleton structure blade, its inflatable skeleton is a bit like the structure of the asymmetrical large feather skeleton of the wing when the bird spreads its wings, and they are also the ray distribution. At one end of the head of the ray airfoil inflatable skeleton structure 1, the inflatable skeletons can be bonded or welded together to form an overall inflatable skeleton structure to fix the structural position of each inflatable skeleton in the ray airfoil inflatable skeleton structure. Since the ray structure of the inflatable skeleton is closer to the tip of the blade, the distance between the skeletons is greater, and the area of ​​the blade supported by each inflatable skeleton is also larger. The structural strength of each inflatable skeleton depends on its own strength. It is supported by the overall structure at one end of the head of the...

Embodiment 3

[0065] Embodiment 3: dragonfly airfoil inflatable skeleton structure blade (as shown in Figure 4)

[0066] The dragonfly airfoil-shaped air-skeleton structure blade refers to a thin blade with the same structure as a dragonfly wing. The dragonfly wing-shaped inflatable skeleton structure blade is a flexible inflatable skeleton structure blade made of composite film materials. Of course, the rigid air-filled frame structure blade can also be made of rigid composite thin materials.

[0067] The inflatable skeleton structure 1 of the blade is not composed of straight inflatable skeletons, but an interrelated network inflatable skeleton structure. If the inflatable skeleton structure 1 is simulated, the skeleton structure is relatively complicated, but due to the use of glue printing It is not difficult to produce dragonfly airfoil inflatable skeleton structure blades, so the inflatable skeleton structure 1 of dragonfly airfoil inflatable skeleton structure blade, the inflatable sk...

Abstract

An inflation frame structure vane relates to a mechanical engineering, in particular to a wind power generator. The inflation frame vane consists of an inflation frame structure 1, a vane skin 2, a supporter liner 3, a vane supporter 4 and a vane shaft 5. The inflation frame in the inflation frame structure 1 is filled with compressed air and the inflation frame is expanded and erects; the radial tensile stress and axial tensile stress are produced in the inflation frame; the inflation frame structure 1 produces powerful mechanical strength on the action of resultant force of the radial tensile stress and the axial tensile stress, in order to support the vane skin to form a long, large and light inflation frame structure vane with high strength. The inflation frame structure vane is divided into two classes: a rigid inflation frame structure vane and a flexible inflation frame structure vane. Figure 1 shows the basic structure diagram of the symmetrical wing-typed inflation frame structure vane.

Description

Technical field [0001] The invention relates to mechanical engineering, in particular to a wind power generator. Background technique [0002] In the prior art, the blades of wind power generators are made of glass fiber composite materials or carbon fiber composite materials. Although carbon fiber has high strength and light weight, it does not show carbon due to the beam structure. Due to the advantages of high tensile strength of fiber materials, the blades are still cumbersome, especially the power of modern wind turbines is increasing. In order to meet the needs of modern high-power wind turbines, the length of the blades and the wind receiving area are increasing. The structure of the blade is also becoming more and more complex, the technical difficulty of manufacturing the blade is increasing, the weight of the blade is also becoming heavier, and the manufacturing cost of the blade is also increasing. Contents of the invention [0003] In order to overcome the def...
