Description

Technical Field

[0001] The utility model relates to the field of wind power generation, in particular to a wind power generation device. Background Technique

[0002] The principle of wind power generation is that the wind drives the rotation of the windmill blades, converts the kinetic energy of the wind into mechanical energy, then uses a speed increaser to increase the rotation speed to the rated speed of the generator, and further drives the generator to generate electricity. According to windmill technology, a breeze speed of about three meters per second (i.e., the degree of a gentle breeze) can start generating electricity.

[0003] In most existing wind power generation devices, the orientation of the fan blades is fixed. When the wind does not blow vertically towards the fan blades, the rotation speed of the fan blades is relatively slow, which reduces the utilization rate of wind energy and results in a decrease in wind power generation.
