[49]
Figure 4 is an exploded perspective view showing a wind speed balancer 200 according to one embodiment disclosed herein.
[50]
The front of the wind speed distribution device 210 are coupled with the track direction of the wind shaft 50.
[51]
The rear of the wind speed distribution device 210 reaches to the vertical center axis (40). Rear and a vertical central axis 40 of the wind speed distribution device 210 may be connected to the guide bearing 222.
[52]
Guide bearings 222 may be made of the same type of bearing with the bearing center axis (42).
[53]
Rear and guide bearing 222 of the wind speed distribution device 210 can be coupled to the fixing pin. Fixing pins on the guide bearings 222, 224 may be formed of the same kind and a fixed pin (44) connecting the central shaft bearing 42 and the wind direction tracking shaft (50).
[54]
The lower part of the wind speed distribution device 210 is coupled with platform 220, the platform 220 is coupled to the tracking direction of the wind shaft 50.
[55]
Position of the platform 220 is preferably located at the bottom center of the relocatable one wind speed balancer 210.
[56]
The wind speed balancer 210 so inclined from the front to the rear, may be the resistance of the wind. 5 is a view showing a use state diagram of the wind speed balancer 210. The
[57]
Wind speed balancer 210 may have a left side 212 and right side 214 may be formed. As the left side of the wind speed distribution apparatus and a right side is shown in Figure 5, it is folded, usually it should not interfere with the wind speed balancer 210 is moved in the wind.
[58]
When a strong wind, dispersing the force of the wind when it exceeds the elastic force of the spring 230 stretches the left side 212 and right side 214 of the wind speed distribution device 210, wind speed as shown in Figure 6, and deceleration can be.
[59]
This prevents the rotary blade 120 is faster electronic device or the power generator unit 100 is damaged by associated rotation.
[60]
4 to according to the embodiment shown in Figure 6, the wind speed distribution device 210 may include a spring 230.
[61]
Spring 230 connecting the left side 212 and right side 214 of the wind speed balancer 210. The Spring 230 is not a, the interference of the left side and the right side so that the folded, wind speed distribution device 210 when a strong wind does not blow the wind movement of the usual, as shown in FIG.
[62]
FIG According to an embodiment the post to the specification shown in Figure 4 the spring 230 may be located in the rear of the wind speed balancer 210. The
[63]
Spring 230 when positioned at the rear of the wind speed distribution device 210, and becomes the wind is going on when the front of the wind speed distribution device 210, first light, to receive more wind resistance can be back more readily earned have.
[64]
If the wind direction balancer 210 or more to mount the eight wind initial velocity 15 meters fire has unfolded four, per second or more, 25 m high winds fire the dog remaining 4 so unfolded rotor blades 120 is to maintain a constant rotation be so.
[65]
In addition, mounting the auxiliary poles in between the rotary blades 120 and the wind direction plate 310 to be in order to prevent sagging due to the length of the rotating shaft becomes longer.
[66]
In addition, by installing the auxiliary pole in the support ring 30 makes it possible to prevent deformation due to the load.
[67]
A rotating blade 120 has up to 12 or more can be also mounted.
[68]
Figure 7 is an exploded perspective view showing a wind direction tracking section 300 in accordance with an embodiment disclosed herein.
[69]
Wind direction tracking section is configured as a wind deflector plate 310, a second bearing (68).
[70]
, The wind direction plate 310 as shown in Figure 7 combines the two plates above and below the vertical axis and the tracking direction of the wind.
[71]
Therefore, when the wind direction is changed, the wind direction plate 310 is a rotary shaft according to the wind direction so that the yaw (Yawing).
[72]
At this time, the central shaft bearing 42, the first bearing 62 and second bearing 68 acts easily help the yaw of the rotating shaft 50 by reducing the frictional force.
[73]
If the wind direction is changed by the wind direction plate 310, the yaw to match the direction of the wind direction and wind direction tracking shaft (50). Accordingly, it is possible to maximize the efficiency of the wind turbine and.
[74]
End of the one embodiment according to the example, the side of the wind direction tracking axis 50. As shown in Figure 7 may be formed of the auxiliary bearing support (320), auxiliary bearing support 320 disclosed herein, the auxiliary bearing may 330 be combined.
[75]
Figure 8 is a rear view showing the rear side of the wind direction tracking section 300 in accordance with one embodiment disclosed herein.
[76]
The auxiliary bearing 330, as shown in Figure 8 is the left and right, each phase may be configured with four auxiliary bearings less. Auxiliary bearing 330 to prevent the wind turbine is rolling (Rolling) serves to enhance the efficiency of the wind turbine. Secondary bearing 330 is the number and combination of the auxiliary bearing by those having ordinary skill is capable of changing.
