Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power generation technology, and in particular to a micro-wind power generation device with a multi-blade array layout. BACKGROUND

[0002] Wind power generation refers to converting the kinetic energy of wind into electric energy. Wind energy is a clean and renewable energy source. At present, wind blades are rotated by wind power to drive a generator to work, thereby realizing wind power generation. However, some wind power generators have high requirements for wind power. The kinetic energy of low-speed micro-wind is insufficient to drive the wind power generator to work. In order to improve the utilization of wind power, a micro-wind power generation device with a multi-blade array layout is proposed.

[0003] In the prior art, most micro-wind power generation devices use more blades to increase the windward area of the blades, so that the micro-wind can also drive the generator to rotate. In such wind power generators, the blades are mostly V-shaped. Although such shaped blades can provide a large force when facing the wind, the wind force will still act on the blades when the wind is reversed, resulting in a decrease in the rotating force and speed of the shaft components, an increase in wind power energy loss, and thus a high requirement for wind power in existing micro-wind power generation.
