For a long time, mankind has been trying to develop a clean alternative energy utilization device that is not exhausted and does not pollute the environment. Such clean alternative energy includes solar energy, wind energy, current energy, tidal energy, geo-thermal energy and bio-thermal energy. Etc.

즉, 베르누이 원리(P1ㅧ V1=P2ㅧ V2)에 따라, 날개분할체(231)의 전면(231a)에서 기류가 흘러가야할 거리가 배면(231b) 보다 크기 때문에 전면(231a)의 기류 속도(V2)가 배면(231b)의 기류 속도(V1) 보다 빠르고, 이에 따라 전면(231a)의 압력(P2)은 배면(231b)의 압력(P1) 보다 낮아지게 된다.That is, according to the Bernoulli principle (P1 ㅧ V1 = P2 ㅧ V2), the air flow velocity (V2) of the front surface 231a is greater 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.
따라서, 날개분할체(231)는 상기와 같은 전면(231a)과 배면(231b)의 형상으로 인해 발생되는 전면(231a)과 배면(231b)의 압력차에 의하여 날개축(232)을 중심으로 회전하여 자세가 조정된다. 이러한 날개분할체(231)의 회전량은 날개분할체(231)의 위치에 따른 선속도에 따라 차이가 있으며, 날개(230)의 외측 단부에 가까울수록 선속도가 커지게 되므로, 결과적으로 하나의 날개(230)에 구비된 다수개의 날개분할체(231)는 날개(230)의 외측 단부에 가까울수록 보다 큰 각도로 회전하게 된다.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.
이처럼 각각의 날개분할체(231)가 자신의 선속도에 상응하는 자세를 갖도록 날개축(232)을 중심을 회전하여 자세가 조정됨으로써, 날개구조체(200)의 최적 회전환경을 제공할 수 있게 된다.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. .
한편, 날개축(232)을 중심으로 한 날개분할체(231)의 회전이 원활히 이루어질 수 있도록 각각의 날개분할체(231)는 베어링(B2)을 매개로 날개축(232)과 결합된다.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.
다시 도 6 및 도 7을 참조하면, 각 날개(230)의 내측 단부에는 삼각형 구조의 지지링크(250)가 설치되고, 상기 지지링크(250)와 날개(230)의 외측 단부(230b)를 연결하는 와이어(260)가 더 포함될 수 있다.6 and 7 again, a triangular support link 250 is installed at the inner end of each wing 230 and connects the support link 250 and the outer end 230b of the wing 230. The wire 260 may be further included.
이때, 상기 지지링크(250)는 날개(230)의 내측 단부(230a)에 위치하는 날개분할체(231-1:도 9에 도시됨)와 일체형의 구조를 갖도록 설치되고, 상기 와이어(260)는 지지링크(250)로부터 연장되어 날개(230)의 외측 단부(230b)에서 날개축(232)과 연결되도록 설치되며, 이러한 지지링크(250)와 와이어(260)를 이용하여 날개(230)의 내외측 단부를 서로 연결하여 지지하여 줌으로써, 날개(230)가 후방으로 하향 경사진 제2 위치(Po2)로 이동한 경우에 발생될 수 있는 날개(230)의 처짐을 방지하게 된다.In this case, the support link 250 is installed to have a structure integral with the wing splitter 231-1 (shown in FIG. 9) located at the inner end 230a of the wing 230, and the wire 260 Is extended from the support link 250 is installed to be connected to the wing shaft 232 at the outer end 230b of the wing 230, by using the support link 250 and the wire 260 of the wing 230 By supporting the inner and outer ends connected to each other, sagging of the wing 230 which may occur when the wing 230 is moved to the second position Po2 inclined downward backward is prevented.
한편, 본 발명에 따른 사축형 윈드 터빈에는 회전모듈(210)을 회전가능하게 지지하고, 날개구조체(200)가 바람의 방향에 따라 방향 전환이 가능하게 하며, 날개구조체(200)와 연동하여 회전축(220)을 밀거나 당김으로써 다수개의 날개(230)가 접혀지거나 펼쳐지도록 하는 지지구조물(300: 도 2에 도시됨)이 더 포함된다.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.

상기 지지구조물(300)은 방향전환모듈(310)과, 경사조절모듈(320)과, 회전지지모듈(330)과, 스프링(340)과, 밀대(350)로 구성된다.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.
상기 방향전환모듈(310)은 고정구조물(100)의 상단부에 고정된 구조로 설치된 원추형 구조의 고정판(311)과, 상기 고정판(311)의 상부에 결합된 채로 회전하는 회전판(312)으로 구성되며, 상기 회전판(312)의 상면 중앙부에는 상방향으로 돌출된 구조를 갖는 지지블록(313)이 형성되어 있다.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.
한편, 상기 회전판(312)의 원활한 회전을 위하여 고정판(311)과 회전판(312)의 사이에 베어링(B3)이 설치된다.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.
상기 경사조절모듈(320)은 두 개의 평판부(321,322)가 약 120도의 각도 간격을 유지하도록 서로 결합된 것으로 형성되며, 중앙부가 지지블록(313)에 회전 가능한 구조로 결합된다.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.
이처럼 설치된 경사조절모듈(320)은 지지블록(313)을 기준으로 전방에 위치한 평판부(321)에 회전지지모듈(330)이 설치되고, 후방에 위치한 평판부(322)에 스프링(340)이 결합된다.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.
상기 회전지지모듈(330)은 경사조절모듈(320)에 설치되며, 회전모듈(210)과 결합되어 회전모듈(210)의 회전을 지지하도록 구성된다.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.
물론, 회전모듈(210)의 원활한 회전을 위하여 회전지지모듈(330)과 회전모듈(210)의 사이에는 베어링(B4)이 설치된다.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.
상기 스프링(340)은 지지블록(313)의 후방에서 방향전환모듈(310)과 경사조절모듈(320)의 사이에 위치하도록 설치된다. 이러한 스프링(340)은 돌풍에 의하여 경사조절모듈(320)이 지지블록(313)을 중심으로 회전하는 경우, 경사조절모듈(320)에 의하여 압축되면서 경사조절모듈(320)을 원위치로 회전시키기 위한 힘을 축적하게 된다.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.
상기 밀대(350)는 방향전환모듈(310)과 회전축(220)을 연결하도록 설치되어 경사조절모듈(320)이 지지블록(313)을 중심으로 회전할 때, 회전축(220)을 밀어 이동시키는 것이다.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. .
이러한 밀대(350)는 하단부가 방향전환모듈(310)에 힌지결합되고, 상단부는 회전축(220)에 전단부에 설치된 고정링(221)과 힌지결합되어 있다.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.
이와 같은 구조로 설치된 밀대(350)는 돌풍에 의하여 경사조절모듈(320)이 지지블록(313)을 중심으로 후방으로 회전하는 경우, 경사조절모듈(320)에 의한 회전축 전단부의 이동 궤적과, 회전축의 전단부와 연결되어 회전하는 밀대(350)의 끝단부 이동 궤적의 차이로 인하여 밀대(350)가 회전축(220)을 밀어주게 되며, 이에 따라 회전축(220)이 후방으로 이동하게 된다.The push rod 350 installed as described above has a movement trajectory of the front end of the rotating shaft and the rotating shaft by the tilt adjusting module 320 when the tilt adjusting module 320 rotates rearward with respect to the support block 313 due to the 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.
이처럼 회전축(220)이 후방으로 이동하는 과정에서 회전축(220)과 각각의 날개(230)를 연결하는 연결링크(240)는 날개(230)를 잡아당겨 날개구조체를 흡사 우산과 같은 형상으로 접어주게 되며, 이로써 날개(230)에 작용하는 풍압을 감소시켜 날개(230)의 파손을 방지하게 된다.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.
상기와 같이 구성된 본 발명의 사축형 윈드 터빈이 작동하며 풍력 에너지를 기계적 에너지로 전환하는 과정을 설명하도록 한다.The bent axis wind turbine of the present invention configured as described above operates and describes the process of converting wind energy into mechanical energy.
본 발명에 따른 사축형 윈드 터빈은 다수개의 날개(230) 중 제1 위치(Po1) 및 이에 근접한 위치에 있는 날개가 풍압을 받아 회전력을 발생시킴으로써, 날개구조체(200)의 회전이 이루어지게 된다.In the bent axis wind turbine according to the present invention, the wing in the first position Po1 and the position adjacent to the plurality of wings 230 receives a wind pressure to generate a rotational force, thereby rotating the wing structure 200.
한편, 날개구조체(200)에 구비된 회전축(220) 또는 회전모듈(210)을 발전기와 연결하여 날개구조체(200)의 회전으로 인해 발생되는 기계적 에너지를 발전기로 전달하게 되면, 풍력 발전기의 구성이 가능하게 된다.On the other hand, by connecting the rotary shaft 220 or the rotary module 210 provided in the wing structure 200 with the generator to transfer the mechanical energy generated by the rotation of the wing structure 200 to the generator, the configuration of the wind generator It becomes possible.
또한, 상기 회전축(220) 또는 회전모듈(210)의 회전력을 이용하여 공기압축기를 구동시키고, 상기 공기압축기에 의해 압축되는 공기를 별도의 탱크에 저장하게 되면, 풍력 에너지의 저장이 가능하게 된다.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.
본 발명에 따른 사축형 윈드 터빈은 날개구조체(200)와 고정구조물(100)의 낮은 높이로 인하여 육상은 물론이고 해상 구조물에도 설치가 용이하며, 돌풍에도 안정적인 구조를 유지할 수 있는 이점이 있다.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.
한편, 날개구조체(200)의 회전시 각각의 날개(230)는 고정구조물(100)의 수직 상방으로 연장되는 제1 위치(Po1)와, 고정구조물(100)의 후방으로 하향 경사진 채로 연장되는 제2 위치(Po2)를 순환하여 회전하게 되고, 이러한 날개(230)의 회전을 지지하는 회전모듈(210) 및 회전축(220)은 수평면과 소정의 각도(θ1)로 기울어진 자세를 유지하게 된다.On the other hand, during the rotation of the wing structure 200, each wing 230 is extended to the first position Po1 extending vertically upward of the fixed structure 100, and inclined downward toward the rear of the fixed structure 100 It rotates by rotating the second position (Po2), the rotation module 210 and the rotation shaft 220 for supporting the rotation of the blade 230 is maintained in a posture inclined at a predetermined angle (θ1) with a horizontal plane. .
한편, 상기 각 날개(230)를 구성하는 다수개의 날개분할체(231)는 자신의 위치에 따른 선속도에 비례하여 발생되는 전면(231a)과 배면(231b)의 압력차에 의해 날개축(232)을 중심으로 회전하여 바람에 순응하는 최적의 자세를 유지하게 되며, 이로써 날개(230)의 회전저항을 최소화할 수 있게 된다.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).
한편, 바람의 방향이 바뀌게 되면, 날개에 작용되는 풍압에 의하여 방향전환모듈(310)의 회전판(312)이 회전함으로써, 날개구조체(200)의 방향 전환이 이루어지게 되며, 이에 따라 바람의 방향이 불규칙하게 바뀌는 지역이나 지형에서도 원활한 작동이 가능하게 된다.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.
한편, 돌풍과 같은 강한 바람에 의하여 날개(230)에 큰 압력이 작용하는 경우, 날개(230)에 작용하는 압력에 의하여 경사조절모듈(320)이 지지블록(313)을 중심으로 후방으로 회전하게 되며, 이때 경사조절모듈(320)과 방향전환모듈(310)의 사이에 배치된 스프링(340)은 압축되고, 회전축(220)은 밀대(350)에 의해 후방으로 이동하게 된다.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.
이와 같은 회전축(220)의 이동에 의하여 다수개의 날개(230)가 회전하며 접혀짐으로써, 날개구조체(200)는 흡사 우산이 접혀진 것과 같은 자세를 취하게 된다. 따라서 각각의 날개(230)에 작용하는 풍압을 감소시켜 돌풍에 의한 날개구조체(200)의 손상을 방지할 수 있게 된다.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.
한편, 돌풍이 잦아들어 날개(230)에 작용하는 풍압이 감소하게 되면, 스프링(340)에 축적된 탄성에 의하여 경사조절모듈(320)이 지지블록(313)을 중심으로 전방으로 회전하게 되고, 이때 회전축(220)이 밀대(350)에 의해 당겨져 전방으로 이동하며, 이러한 회전축(220)의 이동에 의하여 날개(230)가 다시 펼쳐지게 된다.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.
이처럼 본 발명에 따른 사축형 윈드 터빈은 바람의 세기에 따라 날개구조체(200)가 접혀지거나 펼쳐지면서 바람의 세기에 효과적으로 대응할 수 있으며, 지속적으로 풍력 에너지를 기계적 에너지로 전환할 수 있는 이점이 있다.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.
본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims.
