In our daily life, the wind contact is not too big, and the wind direction is not necessarily the same. It is often necessary to adjust the wind for the purpose, which is precisely the drawback of the prior art. In addition, can we consider a combination of multiple types of power generation to maximize power generation efficiency? Disclosure of invention

Another object of the present invention is to overcome the shortcomings of the prior art wind turbines that cannot be adjusted to the wind as the wind direction changes, and to provide a simple structure, easy operation, suitable for promotion, high wind utilization rate, and A layered wind power tower that adjusts the windward side with the wind direction.

In order to achieve the above object, the present invention is achieved by the following technical solutions: A layered wind power generation tower, characterized in that it comprises a tower of a layered hollow structure, the center of which is provided with a hollow wire shaft a pole, the tower top is provided with a solar panel; the tower is provided with a number of wind turbines of the same number as the number of layers, the wind turbines are wound around the conductor shaft and can be The wire shaft rotates within a 360 degree range, and the wire shaft is provided with a line connected to the solar energy plate and the wind power generator.

The invention combines wind power generation and solar power generation, and the respective power generation does not affect each other, thereby maximizing the power generation efficiency; the wind power generator can rotate around the wire shaft, thereby being able to adjust the optimal windward surface of the wind power generator and improve the wind energy. Utilization rate, increase the power generation of the generator.

Preferably, the wind power generator includes a frame, the inner end of the frame is provided with a shaft sleeve, the shaft sleeve is sleeved on the wire shaft, and the outer end of the frame is provided with a bearing seat a motor shaft is disposed in the bearing housing, a generator is connected to an inner side of the motor shaft, and a wind wheel is connected to an outer side of the motor shaft, and a windward surface of the wind wheel and an axial center of the wire shaft Parallel to the line, a wind guide screen is further disposed on the frame between the wire shaft and the wind wheel, and the air guiding screen is perpendicular to the windward side of the wind wheel but opposite to the axis of the wire shaft The lines are parallel.

If the wind direction is not parallel to the wind guide screen, the wind guide screen will be affected by the wind force, which will force the frame to rotate, and finally the wind direction will be parallel to the wind guide screen, and the wind wheel will face the wind direction and the wind direction. Vertical, so that the optimal windward side of the wind wheel can be adjusted, the utilization of wind energy can be increased, and the power generation of the generator can be increased.

The above structure is realized by a freely rotatable blade bushing and a torsion spring structure disposed thereon. When the blade is subjected to a large wind force, the blade bushing naturally rotates in the wind direction direction, and the effective area of the blade windward is reduced from a small time. At this time, the torsion spring is subjected to pressure to be tightened. When the wind becomes smaller or even disappears, the torsion spring is reset and loosened, thereby causing the blade to be reset.

As shown in FIG. 1 , a layered wind power generation tower comprises a tower 1 of a layered hollow structure, which comprises a four-layer structure, and a hollow wire shaft 2 is arranged in the center of the tower 1 , and the tower 1 is The top of the tower is provided with a solar panel 3; the tower 1 is provided with a number of wind turbines 4 of the same number as the number of layers, the wind turbines 4 are wound around the conductor shaft 2 and can be 360 degrees circumferentially of the conductor shaft 2 Rotating in the range, a wire (not shown) connected to the solar panel 3 and the wind turbine 4 is disposed in the wire shaft 2.

As shown in FIG. 2, FIG. 3 and FIG. 4, the wind power generator set 4 includes a frame 41. The inner side end of the frame 41 is provided with a shaft sleeve 42. The shaft sleeve 42 is sleeved on the wire shaft 2, and the frame 41 The outer side of the motor shaft 46 is provided with a motor shaft 46. The inner side of the motor shaft 46 is connected with a generator 45. The outer side of the motor shaft 46 is connected with a wind wheel 44. The windward surface of the wind wheel 44 and the wire The shaft lines of the shaft 2 are parallel, and a wind guide 43 is further disposed on the frame 41 between the wire shaft 2 and the wind wheel 44. The wind screen 43 is perpendicular to the windward side of the wind wheel 44 but parallel to the axis of the wire shaft 2.

The wind wheel 44 includes an inner tray 441, an outer tray 442, a vane shaft 443 and a vane 445. The vane shaft 443 is connected between the inner disc frame 441 and the outer disc frame 442, and the vane shaft 443 is provided with a vane bushing 444 along which the vane shaft 443 can be rotated. The vanes 445 are disposed on the vane bushings 444, and the vanes 445 are gradually widened from the side of the inner tray 441 toward the outer tray 442.

As shown in Fig. 5, a torsion spring 446 is disposed on the blade bushing 444, and the torsion spring 446 abuts against the inner frame 441. A limit pin 447 is disposed on the inner tray 441 corresponding to each of the blades 445.

Practical: The wind guide is not directed to the wind guide screen. As long as the wind direction is not parallel to the wind guide screen, the wind guide screen will be affected by the wind force, thus forcing the frame to rotate, and finally the wind direction is parallel to the wind guide screen, and just the windward windward side It is perpendicular to the wind direction and can be adjusted to the optimal windward side of the wind wheel.
