Problems solved by technology

[0002] The blades of the existing wind-driven generators are single-piece fixed, and the size of the blades of the wind-driven motor cannot be designed according to local conditions. For example, the root of the "wind wheel of a wind-driven generator" disclosed in Chinese patent 00257134.x is connected to the main fan. The leaf is designed as a combination of three or five pieces, which has a small windward surface, low efficiency, and low power generation, and can only be used in specific environments and wind forces.
You can't use one machine for multiple purposes, but one machine with multiple functions

Embodiment Construction

[0015] The flange plate 3 is socketed with the steel bar leaf diameter 2 extending outward from the center of the circle, and the leaf diameter 2 equally divides the circumference, and the leaf diameter 2 expands to the maximum diameter of the leaf sleeve frame. Concentric circles with different sizes and diameters of the leaf cover frame 4 are flexibly connected with the leaf diameter 2 according to the extension of the center of the circle, and the width of the adjacent leaf cover frame 4 is the length of the blade 1, and the aluminum blade 1 is from a small diameter to a large diameter. Gradually extending trapezoidal shape, the multi-leaf 1 is flatly laid in the fan-shaped surface formed by the two-leaf cover frames 4 at the same angle and in the same direction between the two-leaf cover frames 4 .

[0016] Blade diameter 2 length adjustments can also be assembled and spliced.

[0017] The blade diameter 2 and the blade 1 can also be made of other metal materials.

Abstract

The invention relates to a fan blade of a generator. Aiming at the defects of singular blades, low efficiency and low generating power in a traditional wind driven generator, a flange plate is in cup joint with blade diameters outwards extending from the circle center; the circumference is equally divided by the blade diameters; blade sleeve frames are movably connected with the blade diameters; and blades are flatly laid in fan-shaped surface formed by adjacent blade sleeve frames. The lengths of the blade diameters can be extended according to the designed magnitude of the generating capacity of the wind driven generator; the blade sleeve frames are increased or decreased to increase or decrease windward sides; one machine achieves multiple purposes, so that the efficiency is high; the starting air speed is lowered; air wheels are liable to be produced; and the assembly, the extension and the disassembly are convenient.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind blade of the generator. Background technique [0002] The blades of the existing wind-driven generators are single-piece fixed, and the size of the blades of the wind-driven motor cannot be designed according to local conditions. For example, the root of the "wind wheel of a wind-driven generator" disclosed in Chinese patent 00257134.x is connected to the main fan. The leaf is designed as a combination of three or five pieces, which has a small windward surface, low efficiency, and low power generation, and can only be suitable for specific environments and wind power. One machine cannot be used for multiple purposes, but one machine can be used for multiple functions. Contents of the invention [0003] The present invention aims at the existing deficiencies, and provides a wind blade of a generator with high efficiency, large windward surface, and the design can be changed...
