The operation of the wing section 30 and the wing tilt means 40 configured as described above will be described.

When the blade 31 is rotated by the wind, the rotatable movable plate 42 to which the blade fixing portion 42a is coupled to the blade shaft 31a is rotated. When the rotary movable plate 42 is rotated, since the rotary movable plate 42 is coupled to the rotary shaft 41 in a key groove structure, the rotary force of the rotary movable plate 42 is transmitted to the rotary shaft 41 to transmit the rotational power. The rotation force is transmitted to the ratchet gear 52 of 50. At this time, since the solenoid 46 does not generate a magnetic force, the plunger 45 is separated, that is, the rotary movable plate 42 and the tilt disc 47 are separated from each other.

If the wind speed is harder than the wind speed (for example, when a strong wind is generated at a speed of 15 to 20m or more), that is, the wind speed is hard to endure, for example, the wing 30 is tilted. When the tilt motion of the blade is driven by applying electricity to the solenoid 46, the plunger 45 and the solenoid 46 of the rotary movable plate 42 interact with each other to move the rotary movable plate 42 to the tilt disc 47 side. Pull to slide

When the rotary movable plate 42 is slid to the right in the drawing (FIG. 6), it moves to the wing shaft 31a integrally, and the tilt disc 47 in the engaging groove 42b formed in the lower surface of the rotary movable plate 42. The coupling table 47a is inserted into and coupled. Of course, even if the ends of the coupling groove 42b and the coupling table 47a do not always coincide with each other, the rotary movable plate 42 rotates while the coupling table 47a is fitted into the coupling groove 42b. do.

Accordingly, the rotational force of the rotatable movable plate 42 is also transmitted to the tilt disc 47, while the tilt disc 47 also rotates, and the guide rod 48 protruding from the bottom of the tilt disc 47 supports the support disc 49. While moving along the arc-shaped long hole 49a of the end of the arc-shaped long hole 49a, the rotation stops.

When the rotation is stopped in this way, the rotation of the rotary movable plate 42 is stopped, and since the blade 31 still generates the rotational force, the rotary gear 33 of the blade shaft is placed on the upper surface of the rotary movable plate 42. While pulling the installed rack gear 43 is pulled to the other end of the guide groove (43a). That is, the rat gear 43 is moved to the other side of the guide groove 43a while the spring 43b is tensioned, and when the other end is caught, the rotary gear 33 no longer pulls the rack gear 43 and rotates the wing. Tilt (31). For the limit of tilting the wing, a wing tilt stopper (not shown) may be installed to limit the tilting.

Therefore, while the pitch of the wings 31 is minimized with respect to the direction in which the wind blows, the rotational force caused by the wind is no longer generated.

Then, when the driving of the solenoid 46 is stopped during the normal operation, the rotary movable plate 42 is returned to the left side of the drawing, that is, the normal operating position by the restoring force of the spring 44, and the rotary movable plate 42 is When the spring 43b installed on the upper surface of the rotary movable plate 42 returns to the end position of the guide groove 43a by pulling the rack gear 43 in the process of returning, the rotary gear 33 of the wing shaft is rotated. The tilted wing is returned to its normal position to generate a rotational force by the wind.

And, the rotational power transmission means 50, the bracket 51 is fixedly coupled to the shaft housing 21 of the shaft portion 20 and rotatably coupled by a bearing to the main shaft 22 from the inside; The bracket of the wing tilt means 40 is fixedly installed on the one side bracket 51, the rotating shaft 41 of the wing tilt means 40 is inserted inward and installed at the end thereof, and the forward rotational force by the wing is transmitted. And a ratchet gear 52 for blocking a reverse rotational force from the main shaft 21; Bevel gear gear 53 is fixed to the latch gear 52 and the gear 54 is fixed to the main shaft 21 to be coupled to the bevel gear 53 to transfer the rotational force to the main shaft 21. It is configured to achieve.

The rotation power transmission means 50 transmits the rotational force of the blade transmitted through the rotation shaft 41 to the main shaft 22 by using the ratchet gear 52, but is generated from the main shaft 22. Rotation force can be turned away without transmitting to the rotation shaft 410 can protect the wing portion (30).

The present invention, the wing portion 30, the wing tilt means 40, and the rotational power transmission means 50 forms a wing set, the wing set, three wings in the tower (10) The set is installed.

7 is a block diagram of a joint assay that is a direction control means of a multi-stage blade wind generator system according to the present invention.

The direction adjusting means (60) is provided on the top of the tower (10) and the servo motor 61 for rotating the shaft housing 21 in the direction of the wind; Wow; The power transmission means is rotated with respect to the intermediate support of the tower by the rotational force of the servo motor is composed of a joint assay for adjusting the direction of the wing, the joint assay, the main shaft 22 of the shaft portion 20 Main shaft adapter 62 integrally fixed to the shaft, the main shaft adapter 62 and the main shaft adapter 62 are rotatably coupled by a bearing, and the shaft housing coupler 64 fixed integrally with the shaft housing 21; The support adapter 66 which is integrally fixed to the intermediate support 13 of the tower 10, and the support adapter 66 and the bearing are coupled to each other and fixed to the shaft housing coupler 64 in a vertical direction. The cylindrical joint housing coupler 65, and the inside of the joint housing coupler 65 is rotatably coupled by a bearing, the main shaft adapter 62 to transfer the rotational power to the upper and lower parts. Coupled to the comprised by a main joint adapter (63). That is, one servomotor and three plurality of joint assays are configured.

Therefore, when the wind direction signal is applied from the wind direction and wind speed detection means 70, the direction adjusting means 60 drives the servo motor 61 by the wind direction signal. When the servo motor 61 is driven to rotate the shaft housing 21, the shaft housing coupling hole 64 fixedly coupled to the shaft housing 21 and the joint housing coupling fixedly coupled to the shaft housing coupling hole 64 are coupled. The sphere 65 is rotated by the servomotor 61. At this time, the main shaft adapter 62 and the main joint adapter 63 of the inner bearing are rotated together with the main shaft 22, and the outer support zone adapter 66 is also formed of bearing coupling to the tower ( It is possible to adjust the direction while rotating relative to the intermediate support 13 of 10).

Accordingly, since the wing sets are fixed and coupled to the shaft housing 21 as shown in FIG. 6, the wing sets are all rotated to face the wind blowing direction by the rotational force of the servo motor 61. Exercise takes place. At this time, since the gear 53 of the power transmission means 50 and the gear 54 of the main shaft 22 are engaged in the bevel gear configuration, even if the blade set is rotated, the rotation power is normally transmitted because the bevel gear is engaged. There is no obstacle.
