With the rapid development of economy, the consumption speed of energy is also increasing, the shortage of energy becomes a problem which is becoming more and more serious day by day, wind energy is more and more paid attention to by people as a renewable energy source, at present, wind energy is mainly converted into mechanical energy through a windmill and then converted into electric energy through a generator to be utilized, and the windmill can also be directly used as a power mechanism of other devices.

The existing wind driven generator generally can not be driven by a windmill to drive a generator rotor to rotate to generate electricity, in a natural environment, wind often changes irregularly, not only the wind direction changes from time to time, but also the wind magnitude does not change, because the windmill on the wind driven generator is huge, blades on the windmill are narrow, when the wind power is small or breeze, because the windmill can not be driven by enough wind power, the generator rotor is difficult to drive to rotate, the wind power generation is limited, and the requirements of continuous power generation and continuous power supply can not be met. Meanwhile, because wind power is insufficient and cannot be operated, the generator can only be idle, so that resource waste is caused, equipment is rusted and damaged due to long-term stagnation, the windmill needs to keep the same rotating direction, and otherwise voltage instability is caused.

in the above solution, as shown in fig. 3, in the simple model of the present invention, when the plane where the axis of the hinge shaft 51 and the axis of the base shaft 10 are located is perpendicular to the wind direction, the plate surface of the wind vane plate 50 on one side in the wind direction is perpendicular to the wind direction and faces the wind, and the plate surface of the wind vane plate 50 on the other side is parallel to the wind direction and faces the wind, because the pressure of the wind is the same, the larger the wind force applied to the wind face is, and because the windward areas of the wind vane plates on the two sides are different, the wind force applied to the wind vane plates can naturally rotate the windmill. The revolution of the vane plate 50 is accompanied by rotation, and when the vane plate 50 revolves 180 degrees, the vane plate 50 rotates 90 degrees, namely the revolution angle of the vane plate 50: the rotation angle of the vane plate 50 is 2: 1, ensuring that the state of the vane plate 50 at each position is the same when the vane plate revolves to the position, so that the windmill can continuously and stably work, setting a radial line which is consistent with the wind direction on the base shaft 10 as a datum line, and setting the windward end of the datum line as a datum point, so that the datum line is parallel to the direction of the wind vane, when the wind direction changes, the wind vane 20 rotates, and the direction adjusting mechanism drives the base shaft 10 to rotate, so that the datum line is parallel to the direction of the wind vane 20 again and the datum point faces the wind. Since the base shaft 10 rotates following the wind vane 20, that is, the vane 50 revolves relatively to the wind vane 20 is essentially revolved relatively to the base shaft 10. The windward side of the windmill is large, the whole windmill can be pushed to rotate by utilizing wind power to the maximum extent, the windmill can still rotate under breeze, the utilization rate of wind energy is further improved, and meanwhile, the base shaft 10 can rotate along with the wind direction, so that the windmill can stably rotate in any wind direction, and the windmill can rotate along with the wind power and keep unchanged steering.
