In addition, the traditional three-blade wind turbine will generate a huge blowing and overturning torque when a storm blows, and it is easy to be blown and damaged by the storm. At the same time, there are problems such as low wind power utilization, large starting dead angle and reversing dead angle, difficulty in manufacturing, transportation, installation and maintenance, and low power generation efficiency.

It can also be adapted to wind power generation on land, plains, mountains, deserts, islands, offshore wind power and floating offshore wind power generation equipment and wind power generation operations installed on ships. The multi-layer combined wind-collecting vertical wind power generation system adopts a multi-layer combined structure, which solves the problems of difficult manufacturing, transportation, installation and maintenance. At the same time, its wind power generation operation wind area is large, which improves the wind utilization rate and power generation efficiency, thereby improving the adaptability of various wind environments, and increasing the wind power installed capacity and power generation.

Furthermore, due to the wind collecting effect of the windward surface of the wind collecting plate, a vacuum and siphon effect is generated on the leeward surface of the wind collecting plate, which accelerates the airflow on the left and right sides of the fan to be blown into the fan, causing the airflow inside the fan to produce an accelerated rotation effect and flow out at a high speed at the air discharge port; because the airflow is accelerated and pressurized in the wind collecting protection system, the high-speed airflow is accelerated to flow out of the air discharge port, so that the subsequent wind force is continuously accelerated to blow into the fan to continue to increase the wind speed and air pressure, so that the fan blades increase the driving torque and improve the rotational torque, and maintain the continuity and stability of the rotational torque. The present invention enables the wind collecting protection system to always face the positive wind direction, obtain the maximum wind collection volume and the maximum wind force continuous rotation driving torque, so that the wind power generation system can exert the maximum power generation efficiency.
