Description

Technical Field

[0002] The blades of traditional vertical-axis Q-type horizontal-axis wind turbines on the market are made of thin-plate aluminum alloy, and the fan blades are generally 4 to 6 blades. When assembling the fan, the tooth end of the fan blade is inserted into the tooth of the fan disc, and then bent. The disadvantages of the fan assembled in this way are: due to the simple way of fixing the fan blades, the wind turbine is very likely to have blades fall apart and cause damage to the fan under extreme wind speed conditions. Secondly, in high-altitude, cold and ultraviolet areas, after years of operation of wind turbines, the strength of thin-plate aluminum alloy blades decreases significantly. Due to the centrifugal force of the fan blades, the fan blades fall off. At the same time, most of them are single-layer fan blade structures, and the wind energy utilization rate is not high.

The first fixing portion 413 and the second fixing portion 414 are both integrally formed structures with the downwind blade 4 and the upwind blade 6, thereby improving the overall mechanical strength of the downwind blade 4 and the upper wind blade 6.

[0028] First, the first fixing portion 413 and the second fixing portion 414 on both sides of the lower wind blade 4 are respectively passed through the lower mounting tooth openings 11 on the lower disk 1 and the middle disk 10, and then the first fixing portion 413 and the second fixing portion 414 are bent through the operating port 411 so that the first fixing portion 413 and the second fixing portion 414 are respectively fitted with the surfaces of the lower disk 1 and the middle disk 10, and then the first fixing portion 413 and the second fixing portion 414 fix the lower wind blade 4 between the middle disk 10 and the lower disk 1.
