That is, according to the Bernoulli principle (P1 ㅧ V1 = P2 ㅧ V2), the air flow velocity (V2) of the front surface 231a is larger than the rear surface 231b because the distance to which air flow should flow from the front surface 231a of the wing splitter 231. ) Is faster than the air flow velocity V1 of the rear surface 231b, so that the pressure P2 of the front surface 231a is lower than the pressure P1 of the rear surface 231b.

Accordingly, the wing splitter 231 rotates about the wing shaft 232 by the pressure difference between the front surface 231a and the rear surface 231b generated due to the shape of the front surface 231a and the rear surface 231b as described above. Position is adjusted. The amount of rotation of the wing splitter 231 is different depending on the linear velocity according to the position of the wing splitter 231, and the closer to the outer end of the wing 230, the greater the linear speed, and consequently one The plurality of wing splitters 231 provided in the wing 230 is rotated at a greater angle as it is closer to the outer end of the wing 230.

As described above, the attitude is adjusted by rotating the center of the wing shaft 232 such that each wing division 231 has a posture corresponding to its linear speed, thereby providing an optimal rotation environment of the wing structure 200. .

On the other hand, each wing split body 231 is coupled to the wing shaft 232 through the bearing (B2) so that the rotation of the wing split body 231 around the wing shaft 232 can be made smoothly.

On the other hand, the bent axis wind turbine according to the present invention rotatably supports the rotating module 210, the wing structure 200 is capable of changing the direction according to the direction of the wind, in conjunction with the wing structure 200, the rotating shaft A support structure 300 (shown in FIG. 2) is further included to allow the plurality of wings 230 to be folded or unfolded by pushing or pulling 220.

12 is a side view showing the structure of the support structure according to the present invention, Figure 13 is a side view showing a state in which the support structure according to the present invention is inclined backward.

The support structure 300 is composed of a direction switching module 310, the tilt control module 320, the rotation support module 330, the spring 340, the push rod 350.

The redirection module 310 is composed of a fixed plate 311 of the conical structure installed in a fixed structure on the upper end of the fixed structure 100, and a rotating plate 312 while being coupled to the upper portion of the fixed plate 311 The support block 313 having a structure protruding upward is formed at the center of the upper surface of the rotating plate 312.

On the other hand, the bearing B3 is installed between the fixed plate 311 and the rotating plate 312 for smooth rotation of the rotating plate 312.

The inclination control module 320 is formed of two flat plate parts 321 and 322 are coupled to each other to maintain an angle interval of about 120 degrees, the center portion is coupled to the support block 313 in a rotatable structure.

The tilt control module 320 installed as described above is provided with a rotation support module 330 on the flat plate portion 321 located in front of the support block 313, the spring 340 on the flat plate portion 322 located in the rear Combined.

The rotation support module 330 is installed in the inclination control module 320, is coupled to the rotation module 210 is configured to support the rotation of the rotation module 210.

Of course, the bearing (B4) is installed between the rotary support module 330 and the rotary module 210 for smooth rotation of the rotary module 210.

The spring 340 is installed to be located between the direction change module 310 and the inclination control module 320 at the rear of the support block 313. When the spring 340 is rotated about the support block 313 by the inclination control module 320 by the gust, the inclination control module 320 is compressed by the inclination control module 320 to rotate to the original position Will accumulate power.

The push rod 350 is installed to connect the direction switching module 310 and the rotary shaft 220, and when the tilt control module 320 rotates around the support block 313, it pushes the rotary shaft 220. .

The push rod 350 is hinged to the lower end of the direction switching module 310, the upper end is hinged to the fixing ring 221 installed in the front end on the rotating shaft 220.

The push rod 350 installed as described above has a movement trajectory and a rotating shaft of the front end of the rotating shaft by the tilt adjusting module 320 when the tilt adjusting module 320 is rotated rearward with respect to the support block 313 by a gust. Due to the difference in the movement trajectory of the end portion of the push rod 350 which is connected to the front end of the rotating rod, the push rod 350 pushes the rotating shaft 220, and thus the rotating shaft 220 moves rearward.

As such, the connecting link 240 connecting the rotating shaft 220 and the respective wings 230 in the process of moving the rotating shaft 220 to the rear pulls the wings 230 to fold the wing structure into a shape similar to an umbrella. As a result, the wind pressure acting on the wing 230 is reduced to prevent breakage of the wing 230.

In addition, when the air compressor is driven by using the rotational force of the rotary shaft 220 or the rotary module 210, and the air compressed by the air compressor is stored in a separate tank, wind energy can be stored.

Due to the low height of the wing structure 200 and the fixed structure 100, the bent axis wind turbine according to the present invention is easy to install on land as well as offshore structures, and has the advantage of maintaining a stable structure against gusts.

On the other hand, during the rotation of the wing structure 200, each wing 230 is a first position (Po1) extending vertically upwards of the fixed structure 100, and acute angle with respect to the ground to the rear of the fixed structure 100. The second position Po2 extends while being inclined at an angle and rotates, and the rotation module 210 and the rotation shaft 220 supporting the rotation of the blade 230 form an acute angle with a horizontal plane (θ1). Will maintain a tilted position.

On the other hand, the plurality of wing dividers 231 constituting each of the wings 230, the wing shaft 232 by the pressure difference between the front surface (231a) and the rear surface (231b) generated in proportion to the linear velocity according to its position By rotating around the center to maintain the optimum posture in compliance with the wind, thereby minimizing the rotational resistance of the wing (230).

On the other hand, if the direction of the wind is changed, by rotating the rotating plate 312 of the direction switching module 310 by the wind pressure acting on the blade, the direction of the wing structure 200 is made, accordingly the direction of the wind Smooth operation is possible even in irregularly changing areas or terrain.

On the other hand, when a large pressure is applied to the wing 230 by a strong wind, such as a gust, the tilt control module 320 is rotated to the rear about the support block 313 by the pressure acting on the wing 230. At this time, the spring 340 disposed between the inclination control module 320 and the direction switching module 310 is compressed, the rotating shaft 220 is moved back by the pusher 350.

As the plurality of wings 230 are rotated and folded by the movement of the rotary shaft 220, the wing structure 200 takes a posture similar to that of an umbrella. Therefore, it is possible to prevent damage to the wing structure 200 due to the gust by reducing the wind pressure acting on each wing 230.

On the other hand, when the wind pressure is reduced and the wind pressure acting on the wing 230 is reduced, the inclination adjustment module 320 is rotated forward around the support block 313 by the elasticity accumulated in the spring 340, At this time, the rotary shaft 220 is pulled by the pusher 350 to move forward, the wings 230 are unfolded by the movement of the rotary shaft 220.

As described above, the bent axis wind turbine according to the present invention can effectively respond to the strength of the wind while the wing structure 200 is folded or unfolded according to the strength of the wind, and has the advantage of continuously converting the wind energy into mechanical energy.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
