The specific use mode and function of the embodiment are as follows:
when the vertical axis fan 1 is driven by natural wind to rotate, the generator 3 outputs electric energy, the electric energy after rectification and mixing enters a storage battery for storage, meanwhile, the electric energy generated by the high-efficiency photovoltaic panel 201 in the presence of sunlight is also input into the storage battery for storage after rectification and mixing, the stored electric energy can be directly supplied for a direct current electric appliance to work or used for driving an inverter to output power frequency commercial power, if the wind-light complementary power station is a large and medium-sized wind-light complementary power station, the electric energy after frequency conversion and voltage regulation can be sent into a power grid for use, as;
when natural wind acts on the vertical axis fan 1, the cylindrical wind wheel 101 and the flying wing-shaped blades 102 both obtain natural wind energy to drive the vertical axis fan 1 to rotate to do work, and the flying wing-shaped blades 102 can generate a gain effect beneficial to the vertical axis fan 1 while rotating to do work by using wind resistance, such as influencing the aerodynamic characteristics of airflow flowing to the fan, generating lift force, layering airflow, forcing the change of turbulence in the airflow and the like. The lift force reduces the friction force, the formed laminar flow and the changed turbulent flow are beneficial to the vertical axis fan 1 to obtain more wind energy, therefore, the vertical axis fan 1 can rotate at an increased speed, the output mechanical energy is naturally increased, and therefore, under the condition that the same land area and the same occupied space are the same, the beneficial wind receiving area and the output power density of the vertical axis fan 1 in the device are both larger than those of other types of wind machines, and the starting wind speed is low and the sensitivity is high;
when no natural wind exists, the vertical axis fan 1 is not moved, the flying wing-shaped blade 102 is in a vertical state with the ground, as shown in fig. 9, when natural wind acts on the vertical axis fan 1, the included angle between the flying wing-shaped blade 102 and the ground changes within a certain range, as shown in the flying wing-shaped blade 102 at the upper side of fig. 10, at this time, the flying wing-shaped blade 102 increases the kinetic energy obtained by the vertical axis fan 1 to rotate and accelerate, when the natural wind speed approaches or exceeds the maximum value that the vertical axis fan 1 can bear, the flying wing-shaped blade 102 is in a state as shown in the flying wing-shaped blade 102 at the lower side of fig. 10, the resistance of the flying wing-shaped blade 102 is obviously raised, the beneficial gain effect is greatly weakened, the kinetic energy obtained by the vertical axis fan 1 is greatly reduced to be in a deceleration state, at this time, although the kinetic energy obtained by the cylindrical wind wheel 101 is increased, but the kinetic energy increased by the cylindrical wind wheel 101 is not enough to make up the kinetic, in order to compensate for the reduction of the total kinetic energy of the vertical axis fan 1, the flying wing-shaped blades 102 can automatically change the angle to allow part of the gain effect to appear, and in such a circulating manner, the kinetic energy acquired by the whole vertical axis fan 1 can be maintained in a dynamic balance state, the rotating speed of the vertical axis fan 1 can be stabilized within a designed maximum value, and the stall phenomenon cannot occur, so that the purpose of automatically protecting the vertical axis fan 1 is achieved.
