A kind of wind power generation device

Abstract

The invention relates to a wind power generation device which is provided with an integrated generation device. The wind power generation device comprises a fixed center shaft and a fan blade rotary drum. A center sleeve is arranged in the middle of the fan blade rotary drum. A plurality of blades used for collecting wind power are arranged outside the center sleeve. The fan blade rotary drum is movably sleeved on the fixed center shaft through the center sleeve in a spaced mode so that the fan blade rotary drum can freely rotate relative to the fixed center shaft. The fixed center shaft and the center sleeve are all made of permeability magnetic materials. Permanent magnets are arranged on one wall face, corresponding to the outer wall of the fixed center shaft, of the inner wall of the center sleeve. Winding coils corresponding to the permanent magnets are arranged on the other wall face, corresponding to the inner wall of the center sleeve, of the outer wall of the fixed center shaft. The wind power generation device is more compact in structure through adoption of a perpendicular axial wind power generation system of a novel motor, enables cost to be reduced through adoption of the integrated design, and has the advantages of being high in structural rigidity, better in heat dissipation effects, long in service life, fewer in the number of parts, and simple in structure.

[0002] With the development of science and technology and the development of new energy sources, various wind power generation devices are more and more widely used. The existing wind power generation devices include fan type power generation devices and rotary drum type power generation devices. The structure is composed of the central shaft of the blade rotor to drive the generator (such as Figure 1-2 shown), Figure 1-2 What is shown is a drum-type power generation device using a traditional generator. This power generation device has the following disadvantages: First, the traditional generator and the wind blade drum are two parts, and the wind power generation device formed after the two are assembled has many parts. The cost is high; secondly, the traditional generator has low efficiency and poor cooling effect; thirdly, the traditional wind power generation device has poor anti-typhoon performance, and the position of the connecting shaft between the traditional generator and the wind blade rotor is prone to breakage accidents when encountering a typhoon; other Fourth, the traditional permanent magnet generator has a cogging effect, so the starting force is relatively large, so it cannot work at low wind speeds, and requires high wind speeds to drive the work
