First step, controller 2 is according to current wind direction, can the adjusting device all the time with the wind direction perpendicular, controller 2 control rotating electrical machines 11 rotates, directly drive gear 12 when rotating electrical machines 11 is rotatory and rotate, because the interact of dynamics, again because a ring gear 10 and bracing piece 1 fixed connection, so drive connecting rod 8 when gear 12 is indirect when rotatory and rotate, the rotation of connecting rod 8 can directly drive whole power generation facility and rotate, thereby reach the purpose perpendicular with the wind direction. The rotation of the equipment can be smoother and more stable due to the action of the pressure bearing 33, and the supporting rod 1 and the connecting rod 8 can be directly meshed with each other due to the action of the circular clamping block 6, so that the falling-off is avoided and the accidents are caused. The protective cover 9 can protect the steering device, so that the steering device is more durable.

And in the second step, the controller 2 controls the first hydraulic cylinder 14 to stretch and retract so as to directly drive the power generation bin 13 and the connecting rod 8 to adjust the angle, thereby improving the flexibility of the equipment. Since the generator set 15 has rated power, when the wind is high, the rotating blades 28 will rotate faster, which will not only damage the equipment, but also lose part of the wind energy, causing waste. A mechanism is required to recover the wind energy again. The controller 2 controls the second hydraulic cylinder 21 to extend, when the second hydraulic cylinder 21 extends, the second bearing 20 is directly driven to move, due to the effect of the annular groove 19, the second connecting pipe 18 can move along with the second bearing 20, due to the effect of the sliding wheel 34, the second connecting pipe 18 can move more smoothly, the first connecting pipe 16 and the second connecting pipe 18 are in a synchronous rotating state, and the first connecting pipe 16 directly drives the second toothed ring 24 to be close to the auxiliary generator 25 to generate electricity. Thereby allowing the auxiliary generator 25 to share a portion of the energy.

And thirdly, the controller 2 controls the second rotating motor 31 to rotate, the rotating end of the second rotating motor 31 directly drives the third gear 32 to rotate, and the third gear 32 can directly drive the rotating blades 28 to rotate when the third gear 32 rotates due to the rotation of the third bearing 27, and the inner part of the adjusting device can be cleaner due to the action of the first sealing gasket 35.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
