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.

A follow-up regulating windmill comprises a base shaft 10 which is vertically arranged, a rotating sleeve 30 which is used as a power output shaft is sleeved on the base shaft 10, a rotating frame 40 is fixedly arranged on the circumferential direction of the rotating sleeve 30, a vane plate 50 is hinged on the rotating frame 40, the axial direction of a hinge shaft 51 of the vane plate 50 is parallel to the axial direction of the base shaft 10, at least two vane plates 50 are uniformly arranged at intervals in the circumferential direction of the rotating sleeve 30, the vane plate 50 rotates around the axial core 51 of the hinge shaft when the vane plate 50 revolves around the axial core of the base shaft 10, the revolving direction of the vane plate 50 is the same as or opposite to the rotating direction of the vane plate 50, a steering mechanism drives the base shaft 10 to perform attitude regulation rotation following the wind direction according to the wind direction, the attitude regulation rotation meets the following adaptive relation, when the plane where the axial core 51 of the hinge shaft and the axial core of the rotating sleeve 30 is vertical to the wind direction, the plate surface of one side vane, when the vane plate 50 revolves 180 degrees along with the rotary sleeve 30, the vane plate 50 rotates 90 degrees to make the plate surface parallel to the wind direction.

In the above solution, as shown in fig. 6, 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.

The same-core fixed base chain wheel 11 is arranged on the base shaft 10, the same-core fixed driven chain wheel 52 is arranged on the hinge shaft 51 of the wind vane plate 50, the base chain wheel 11 is connected with the driven chain wheel 52 through a chain 60, and the transmission ratio between the base chain wheel 11 and the driven chain wheel 52 is 2: 1. thus, when the vane plate 50 revolves 180 ° relative to the base shaft 10, the driven sprocket 52 of the vane plate 50 revolves 180 ° around the core of the base sprocket 11 of the base shaft 10, which corresponds to the base sprocket 11 rotating 180 ° relative to the chain 60, the driven sprocket 52 rotates 90 ° with it, and the vane plate 50 rotates 90 ° because the driven sprocket 52 is fixed concentrically with the hinge shaft 51 of the vane plate 50. The linkage mechanisms such as the chain 60 and the like in the scheme can be arranged above the vane plate 50 and below the vane plate 50, the linkage of revolution and rotation of the vane plate 50 is completed through a mechanical structure, the linkage is simple and convenient, errors are not prone to occurring, and complicated wiring is omitted for electric control.

Tension pulleys 70 are provided outside the chain 60 between the adjacent driven sprockets 52 and between the base sprocket 11 and the driven sprocket 52. The tensioner 70 prevents the chain 60 from loosening and falling off.

The wind vane 20 is arranged at the upper end of the base shaft 10, a proximity switch is arranged between the base shaft 10 and the wind vane 20, and the worm gear mechanism 80 drives the base shaft 10 to rotate so that the proximity switch reaches a set position relative to the wind vane 20. Therefore, the base shaft 10 and the wind vane 20 rotate synchronously, the turbine and worm mechanism 80 forms a certain rotation limit on the base shaft 10 to prevent the rotation of the rotating sleeve 30 from driving the base shaft 10, and the turbine and worm mechanism 80 can be arranged at the lower end of the base shaft 10 and is convenient to overhaul and arrange circuits.

The rotating frame 40 comprises a mounting seat 41 fixedly arranged at the upper part and the lower part of the rotating sleeve 30, the mounting seat 41 is cylindrical with external flanges at the upper end and the lower end, one end of the I-shaped beam 42 is connected with the flanges at the upper end and the lower end of the mounting seat 41 through bolts, the other end of the I-shaped beam is horizontally suspended, and the wind vane plate 50 is hinged between the suspended ends of the I-shaped beam 32 and the lower I-shaped beam. All parts on the windmill are in the shapes of straight rods, plates and the like with simple structures, so that the transportation and the assembly are convenient.

The vane plate 50 includes an outer frame 53 hinged on the rotating frame 40, and canvas 54 is stretched and tensioned in the outer frame 53 through a rope. The lighter weight of the canvas 54 reduces the overall weight of the windmill for wind propulsion, while allowing direct replacement of the canvas when damaged without replacing the entire vane plate 50.

The vane plates 50 are arranged in multiple layers in the axial direction of the base shaft 10. The wind blades 50 arranged in multiple layers can further increase the windward side.
