As a kind of preferred version of the present utility model, described fan blade is connected on external rotor and the internal rotor by strut respectively, and described fan blade and strut flexibly connect.

As another preferred version of the present utility model, described strut end is provided with pin, and strut fixedly is provided with running shaft on the position of fan blade, and fan blade is fixed on separately the running shaft, can do rotatablely moving of 90 degree; Strut is connected on external rotor and the internal rotor.

The wind generating unit that the utility model provides, owing to be provided with double rotor, inner and outer rotors is all rotatablely moving and is making relative rotary motion, double-deck fan blade does relative motion and has improved the rotating speed of electricity generating device under equal wind speed, makes generated energy bigger than prior art single rotor wind generating unit; Wind generating unit of the present utility model does not in addition need to pacify the structure of carbonic acid and slip ring, has reduced the hidden danger of maintenance.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:

The structural representation of the wind generating unit that Fig. 1 provides for the utility model embodiment;

Fig. 2 is the connection diagram of fan blade among the utility model embodiment;

Fig. 3 is a present embodiment fan blade working principle schematic representation.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.

As shown in Figure 1, the vertical shaft dual-rotor wind power generation device that present embodiment provides comprises stationary axle 6 and rotor, and described wind generating unit comprises external rotor 1 and internal rotor 2:

Described external rotor 1 is arranged on the stationary axle 6 by two bearings 5, and fan blade 7 is arranged on the external rotor 1, and described external rotor 1 is provided with magnet 3;

Described internal rotor 2 holds by two axles 5 and is arranged on the stationary axle 6, and fan blade 7 is arranged on the internal rotor 2, and described internal rotor 2 is provided with coil 4.

When fan blade 7 is subjected to wind-force, make external rotor 1 do clockwise motion with respect to stationary axle 6, drive magnet 3 rotations on the external rotor, produce the magnetic field that turns clockwise; And internal rotor 2 also is loaded on the stationary axle 6 by bearing 5, and make the coil 4 on the internal rotor be positioned at the magnetic field of external rotor, internal rotor is done when being subjected to wind-force and is rotated counterclockwise, drive coil 4 and in the clockwise magnetic field of external rotor, do counterclockwise motion, thereby the generation electric field sends electric power, and the center of electricity generating device axle is anodal, the surface is a negative pole, forms complete power generation system.Because inner and outer rotors is all being made relative rotary motion, make generated energy bigger than common single rotor.

The wind generating unit that present embodiment provides can come the lifting surface area and the radius of this blade of designing and calculating according to the requirement of wind generating unit output in conjunction with local weather conditions and data.

The wind generating unit that present embodiment provides, owing to be provided with double rotor, inner and outer rotors is all rotatablely moving and is making relative rotary motion, and double-deck fan blade does relative motion and improved the rotating speed of electricity generating device under equal wind speed, makes generated energy bigger than prior art single rotor wind generating unit; Wind generating unit does not need to pacify the structure of carbonic acid and slip ring in addition, has reduced the hidden danger of maintenance.

In order to make fan blade 7 can adapt to the wind-force of any wind direction, described fan blade 7 is connected on external rotor 1 and the internal rotor 2 by strut 8 respectively, described fan blade 7 and 8 movable connections of strut.The mode that flexibly connects is a lot, in the present embodiment, the articulated type alive that can partly rotate displacement that is connected to of fan blade 7 and strut 8 is connected, promptly pin 10 is set at strut 8 ends, strut 8 fixedly is provided with running shaft 11 on the position of fan blade, fan blade is fixed on separately the running shaft 11, can do rotatablely moving of 90 degree; Strut 8 is connected on external rotor 1 and the internal rotor 2 (as shown in Figure 2).As shown in Figure 3, fan blade 7 and fan blade 9 all are fixed on separately the running shaft, can do rotatablely moving of 90 degree, when wind is gone into wind direction when blowing over, when fan blade 7 rotates to the position vertical with wind direction after being subjected to wind-force, be subjected to stopping of pin 10, make fan blade 7 with the maximum area wind-engaging, promote electricity generating device motion generating, fan blade 9 is subjected to forward the position parallel with wind direction to behind the wind-force simultaneously, makes the wind-receiving face minimum of fan blade 9, reach minimum resistance, make full use of wind energy, reduced the head-on wind-force stress of king-post, increased the reliability and stability of king-post.This structure can be made the multi-disc fan blade increases stress surface, improves generated energy.
