Technical Field

[0001] The invention relates to a wind power generation device based on airflow distribution technology, belonging to the field of wind power generation. Background Art

[0002] Wind is a clean energy with great potential. The process of converting the kinetic energy of wind into electrical energy is wind power generation. Wind power generation is very environmentally friendly. At present, with the vigorous development of clean energy, the application of wind energy has become increasingly important. The Chinese patent with application number 202210273330.2 discloses "a wind power generation device, the wind power generation device includes a wind wheel mechanism and a dual-shaft generator; the wind wheel mechanism includes a front wind wheel and a rear wind wheel; a first rotor and a second rotor are respectively arranged at both ends of the dual-shaft generator, the front wind wheel is connected to the first rotor through a first rotating shaft, and the rear wind wheel is connected to the second rotor through a second rotating shaft; the front wind wheel includes a plurality of front blades; wherein the front blade includes an inner blade span, a middle blade span and an outer blade span connected in sequence, and the maximum chord length of the middle blade span is less than the maximum chord length of the outer blade span so as to guide the fluid to flow to the rear wind wheel. The wind power generation device of the present invention has the advantages of high power generation efficiency, compact layout and land saving."

[0003] The above technical scheme only solves the problems of low power generation efficiency, large footprint and instability of existing wind power generation devices. At present, vehicles using clean energy, such as electric vehicles, will be subject to air resistance when traveling at high speeds. When the car is traveling at high speeds, a large amount of wind energy can be utilized, and wind power generation can be used to charge and power small electrical equipment to increase energy conservation and emission reduction. However, existing cars often cannot make good use of wind energy for wind power generation. On the one hand, the power generation efficiency of wind power generation equipment is not high, and the car cannot distribute and utilize the generated air flow well when traveling at high speed. On the other hand, when using wind power generation equipment, the process of converting wind energy into mechanical energy and then into electrical energy is often accompanied by the conversion of heat energy. The equipment will generate a lot of heat after working for a long time, causing the equipment temperature to rise, affecting the normal operation of the wind power generation equipment.
