본 발명은 가변식 다단 수직축 풍력 발전기에 관한 것으로, 특히 다수개의 허브와 상기 허브에 맞물리는 다수개의 날개를 부착하고, 바람의 세기에 따라서 상기 날개를 접거나 펼수 있도록 한 것을 특징으로 하는 가변식 다단 수직축 풍력 발전기에 관한 것이다.The present invention relates to a variable multi-stage vertical axis wind power generator, and in particular, a plurality of hubs and a plurality of blades coupled to the hub, and the variable multi-stage characterized in that the wings can be folded or unfolded according to the strength of the wind. A vertical axis wind power generator.

풍력은 주로 발전 분야에 많이 도입되고 있지만 펌핑 및 열변환 등의 분야에도 이용되고 있는 에너지원이다. 1990년대이후 기후변화 협약으로 인해 온실가스 감축이 발등에 떨어진 급박한 과제로 등장하면서 풍력발전은 화력이나 원자력 발전에 대응한 대안 중의 하나로 국내의 활용 가능성이 높게 인식되는 계기가 되었고 현재는 매우 빠른 속도로 발전하는 단계에 있다.Although wind power is mainly introduced in the power generation field, it is an energy source used in fields such as pumping and heat conversion. Since the 1990s, the climate change agreement has emerged as an urgent task in which GHG reduction has emerged. It is in the stage of development.

풍력발전기는 날개의 회전축이 놓인 방향에 따라 구분하면 수평축 발전기와 수직축 발전기가 있는데, 수직축 발전기는 수평축에 비해 날개면적이 크고 거추장스럽기 때문에 현재 풍력발전기 시장에서 수평축 발전기가 주류를 이룬다. 그러나 수평축 발전기는 풍차날개가 수평으로 뻗은 상태이기에 날개가 처지는 감이 있고, 따라서 날개의 처짐을 방지하려면 강도 및 경도가 높은 고급재료를 사용하여야 하며, 통상 철금속 등을 이용하여 제조할 경우는 중량이 무겁고 회전에 영향을 미침은 물론 가격 또한 고가인 문제점이 따르게 된다.Wind turbines are divided into two directions according to the direction in which the rotational axis of the blades is placed. There are horizontal generators and vertical generators, which are mainstream in the current wind turbine market because the wing area is larger and more cumbersome than the horizontal generators. However, the horizontal axis generator has a sense of sagging because the windmill wings are horizontally stretched. Therefore, high-strength materials with high strength and hardness should be used to prevent sagging of the windmill. This is not only heavy and affecting the rotation, but also expensive.

수직축 발전기의 일예로서 지상에 세워진 기둥(컬럼) 주위에 볼록한 형태의 큰 날개를 부착한 상태로 저속 회전하는 다레이어스 터빈은 상기한 수평축 발전기의 단점을 지니지 않으며 풍향에 무관하게 작동된다. 그러나 근본적으로 수평축 발전기에 비해 회전익에 작용하는 압력이 적기 때문에 설치공간이 넓은 반면 발전 효율이 나쁘다는 단점을 극복하지 못한다.As an example of a vertical axis generator, a multi-layer turbine that rotates at low speed with large convex wings attached to a column (column) standing on the ground does not have the disadvantages of the horizontal axis generator and operates regardless of the wind direction. However, it does not overcome the disadvantage that the installation space is large and the power generation efficiency is bad because the pressure applied to the rotor blade is less than the horizontal axis generator.

또한, 때때로 겪는 일이기는 하지만 초대형 태풍의 영향으로 강풍이 불어오면 회전익의 속도 변동이 심하여 발전이 중단되기도 하고 강풍을 따라 날아드는 파편에 의해 파손이 쉽다. 고급 자재를 사용해야 하는 수평축 발전기에 있어서 유지, 보수비용이 증가하여 더욱 경제성을 저하시키는 요인이 된다.In addition, although it sometimes happens, when the strong wind blows due to the influence of a large typhoon, the speed of the rotor blades fluctuates so that power generation is interrupted, and it is easy to be damaged by debris flying along the strong wind. In the horizontal axis generator that requires the use of high quality materials, the maintenance and repair costs are increased, which causes further economic deterioration.

본 발명은 상기와 같은 문제점을 해결코자 하는 것으로, 수직축이 다단으로 형성된 발전기 시스템을 제공하고, 또한 바람이 일정이상이면 날개를 접도록 설계하여 수평축 발전기의 단점을 보완하고 아울러 강력한 발전시스템을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, to provide a generator system formed in a multi-stage vertical axis, and to design the folding of the blade if the wind is above a certain level to compensate for the shortcomings of the horizontal axis generator and to provide a powerful power generation system The purpose is.

도 3은 본 발명의 단면도로서,3 is a cross-sectional view of the present invention,

본 발명의 가장 큰 특징은 수직축 지지형 발전기를 다단으로 제작할 수 있다는 것인바, 이러한 본 발명의 구성요소를 살펴보면, 지면에 지지되는 원통 형상의 하우징(100)과, 상기 하우징(100) 내부에 설치되는 유압 실린더(200)와, 상기 유압 실린더의 외주연에 설치되는 원통형의 동력전달수단(300)과, 상기 동력전달수단(300) 외부에 결합되는 사각형태의 허브(400)와, 상기 허브(400)에 결합되는 날개 (500)로 이루어진다.The greatest feature of the present invention is that the vertical axis support generator can be manufactured in multiple stages. Looking at the components of the present invention, the cylindrical housing 100 supported on the ground and installed inside the housing 100 The hydraulic cylinder 200, the cylindrical power transmission means 300 is installed on the outer periphery of the hydraulic cylinder, a rectangular hub 400 coupled to the outside of the power transmission means 300, and the hub ( Consisting of wings 500 coupled to it.

그리고, 상기 날개(500)의 개폐수단으로서, 유압실린더 상부에 설치되어 유압실린더의 작동에 따른 피스톤(210)의 상하 유동에 따라 움직이는 날개 개폐장치(600)와, 상기 날개 개폐장치(600)의 상하 유동에 상응하여 유동하며 허브(400)가 슬라이딩 결합된 날개 개폐용 축(700)과, 상기 날개 개폐용 축(700)의 일지점에 설치되는 기억자 형태로서 타측 끝단이 연결핀(800)을 통해 날개 지지축(510)에 동력을 전달하는 날개 개폐로드(900)를 포함하여 구성한다.And, as the opening and closing means of the wing 500, the wing opening and closing device 600 and the wing opening and closing device 600, which is installed on the hydraulic cylinder and moves in accordance with the vertical flow of the piston 210 according to the operation of the hydraulic cylinder, Wing opening and closing shaft 700 and the hub 400 is slidingly coupled corresponding to the up and down flow, and the memory terminal is installed at one point of the wing opening and closing shaft 700 as the other end of the connecting pin 800 It comprises a wing opening and closing rod 900 for transmitting power to the wing support shaft 510 through.

상기와 같이 구성되는 본 발명의 구성을 보다 상세히 설명하기로 한다.The configuration of the present invention configured as described above will be described in more detail.

상기 하우징(100)은 원통형상으로서 바람의 저항을 회피할 수 있도록 구성되고 하부는 지면에 매설된다.The housing 100 has a cylindrical shape and is configured to avoid wind resistance, and the lower part is embedded in the ground.

상기 하우징(100)의 상부에는 수평 지지대(110)가 설치되고, 상기 지지대(110)에는 수직한 일자 형태의 유압 실린더(200)가 설치된다.A horizontal support 110 is installed at an upper portion of the housing 100, and a hydraulic cylinder 200 having a vertical straight shape is installed at the support 110.

상기 유압 실린더(200)는 유압에 따라서 피스톤(210)을 상부 또는 하부로 일정거리 이동시키는 구조이다.The hydraulic cylinder 200 has a structure in which the piston 210 is moved up or down a certain distance according to the hydraulic pressure.

상기 유압 실린더(200)의 외주연에는 베어링(220)을 지지수단으로하여 원통형의 동력전달수단(300)이 결합되며, 상기 동력전달수단(300)의 외주연에는 허브(400)가 결합되어 있다.A cylindrical power transmission means 300 is coupled to the outer periphery of the hydraulic cylinder 200 with the bearing 220 as a support means, and a hub 400 is coupled to the outer periphery of the power transmission means 300. .

그리고, 허브(400)에는 니은지 형태의 날개 지지축(510)이 회동가능토록 축 결합되고, 상기 날개 지지축(510)에는 반원형태의 날개(500)가 결합된다.In addition, the hub 400 has a needle supporting shaft 510 in the form of a rotatable shaft so as to be rotatable, and the wing supporting shaft 510 has a semicircular blade 500 coupled thereto.

이에 따라 날개(500)가 펼쳐진 상태에서 바람의 영향을 받아 회전하게 되면 허브(400)가 회전하고 이에 따라 동력전달수단(300)이 회전하여 발전동력을 얻는다.Accordingly, when the blade 500 is rotated under the influence of the wind in the unfolded state, the hub 400 rotates and thus the power transmission means 300 rotates to obtain power generation power.

그리고, 상기 동력 전달수단(300)은 동력중계수단(310)을 거처 전력발생장치(320)에 기계적 에너지를 출력하여 전기적 에너지로 바꿀 수 있도록 한다.In addition, the power transmission means 300 outputs mechanical energy to the power generating device 320 via the power relay means 310 so as to be converted into electrical energy.

이하에서 날개의 접이식 특성을 설명하면 다음과 같다.Hereinafter, the folding characteristics of the wings will be described.

본 발명의 날개(500)는 접거나 펼칠 수 있도록 설계하였는바, 이는 바람이 적당히 불 때에는 날개(500)를 전속력으로 회전시킬 수 있도록 하고, 태풍등으로 인하여 바람이 너무 강하게 불 때에는 날개(500)를 접어서 부러지가나 파손되는 것을 막도록 하기 위함이다.The wing 500 of the present invention is designed to be folded or unfolded, which allows the wing 500 to rotate at full speed when the wind blows appropriately, and the wing 500 when the wind blows too strongly due to typhoons. This is to prevent the breakage or breakage by folding.

이를 위해 본원발명에서는 날개(500)를 접거나 펼수 있는 구성을 구비하고 있는바, 유압실린더(200)와, 피스톤(210)과, 날개개폐장치(600)와, 날개개폐용 축(700)과, 날개개폐로드(900)와, 연결핀(800)을 구비하였다.To this end, the present invention is provided with a configuration that can be folded or unfold the blade 500, the hydraulic cylinder 200, the piston 210, the wing opening and closing device 600, the wing opening and closing shaft 700 and , Wing opening and closing rod 900 and the connecting pin 800 was provided.

먼저, 날개(500)를 펼치는 동작을 살펴보기로 한다.First, the operation of unfolding the wing 500 will be described.

상기 유압 실린더(200)가 피스톤(210)을 하부로 하강시키면 날개개폐장치(600)가 하부로 하강하고 이에 따라 날개 개폐용축(700)이 하강한다.When the hydraulic cylinder 200 lowers the piston 210 downward, the wing opening and closing device 600 descends to the bottom and thus the wing opening and closing shaft 700 descends.

그러면 상기 날개 개폐용 축(700)에 연결된 기억자 형태의 날개 개폐로드(900)가 하강하고 이에 따라 연결핀(800)이 눌려지면서 날개지지축(510)을 회전시켜 날개(500)가 90도로 펼쳐지도록 한다.Then, the wing opening and closing rod 900 of the shape of the memory connected to the wing opening and closing shaft 700 is lowered and thus the connecting pin 800 is pressed to rotate the wing support shaft 510 to rotate the wing 500 to 90 degrees To expand.

이때 상기 허브(400)는 동력전달수단(300)에 고정되어 있으므로 날개 개폐용 축(700)만이 허브(400)로부터 아래방향으로 유동한다.At this time, since the hub 400 is fixed to the power transmission means 300, only the blade opening and closing shaft 700 flows downward from the hub 400.

물론, 이때 날개 개폐로드(900)와 연결핀(800)은 가변적으로 유동하여야 하기 때문에 날개 개폐로드(900)에는 장공이 형성되고, 상기 장공에 결합되는 연결핀(800)은 장공을 왕복으로 유동할 수 있도록 한다.Of course, at this time, since the wing opening and closing rod 900 and the connecting pin 800 must be variably flowed, a long hole is formed in the wing opening and closing rod 900, and the connecting pin 800 coupled to the long hole flows in the reciprocating long hole. Do it.

즉, 날개 개폐로드(900)를 하강하여 연결핀(800)을 하강시에 연결핀(800)이 날개지지축(510)을 중심으로 회전운동을 하게 되므로, 최초에는 연결핀(800)의 끝지점이 날개 개폐로드(900)에 결합되고 점차 연결핀(800)이 하강하면서 연결핀(800)의 끝지점이 날개 개폐로드(900)의 바깥쪽으로 이동하게 된다.That is, the lowering of the wing opening and closing rod 900, when the connecting pin 800 is lowered when the connecting pin 800 is rotated about the wing support shaft 510, the end of the connecting pin 800 first The point is coupled to the wing opening and closing rod 900 and gradually the connecting pin 800 is lowered, the end point of the connecting pin 800 is moved to the outside of the wing opening and closing rod 900.

이러한 운동은 왕복운동을 회전운동으로 바꾸어 주어야 하는 상황이므로, 반드시 날개 개폐로드(900)와 연결핀(800)은 좌우로 유동가능토록 결합되어야 한다.Since this movement is to change the reciprocating motion to the rotational motion, the wing opening and closing rod 900 and the connecting pin 800 must be coupled to be able to flow from side to side.

또한, 날개(500)를 접을 시에는 유압실린더(200)를 작동시켜 피스톤(210)을 상승시키고, 이에 따라 날개 개폐장치(600)가 상승하게 된다.In addition, when the wing 500 is folded, the hydraulic cylinder 200 is operated to raise the piston 210, and thus the wing opening and closing device 600 is raised.

날개 개폐장치(600)가 상승하면 날개 개폐용 축(700)이 상승하고 이에 따라 연결핀(800)이 상승하며 날개 지지축(510) 아래로 회전시키게 된다.When the wing opening and closing device 600 rises, the wing opening and closing shaft 700 rises and thus the connecting pin 800 rises and rotates below the wing support shaft 510.

이에 따라 상기 날개(500)는 하우징(100)에 바짝 달라붙게 되어 바람의 영향을 받지 않게 되므로 파손의 위험에서 벗어나게 되는 것이다.Accordingly, the wing 500 is stuck to the housing 100 so that it is not affected by the wind, so that the wing 500 is released from the risk of breakage.

이하에서 본 발명의 전체 동작을 살펴보면 다음과 같다.Looking at the overall operation of the present invention as follows.

먼저, 바람의 세기가 기준이하이면 날개를 90도로 활짝 펼치는바, 날개개폐장치(600)를 하강하여 날개(500)가 펼쳐진 상태를 유지하며, 이때 날개(500)가 회전하면 허브(400)가 회전하고 이에 따라 원통형의 동력전달수단(300)이 회전한다.First, if the strength of the wind is less than the reference bar to spread the wings wide 90 degrees, the wing opening and closing device 600 is lowered to maintain the wing 500 unfolded, the blade 500 is rotated when the hub 400 is rotated Rotate and thus the cylindrical power transmission means 300 rotates.

이에 따라 동력전달수단(300)에 연결된 동력중계수단(310)이 회전하고 전력 발생장치(320)에 기계적인 동력을 전달하여 전기를 발생시킨다.Accordingly, the power repeater 310 connected to the power transmission means 300 rotates and transmits mechanical power to the power generator 320 to generate electricity.

그리고, 이와 더불어 날개 개폐장치(600) 및 날개 개폐로드(900) 역시 회전한다.In addition, the wing opening and closing device 600 and the blade opening and closing rod 900 also rotates.

그리고, 바람의 세기가 기준이상이면 날개를 접어야 하는바, 날개개폐장치(600)를 상승하여 날개(500)가 접혀진 상태를 유지하며, 이때에는 날개(500)가 회전하지 않으므로 동력전달수단(300)이 회전하지 않게 되고 따라서 동력중계수단(310)이 회전하지 않아 전력발생장치(320)로부터 전력이 생산되지 않는다.And, if the strength of the wind is higher than the standard bar to be folded, the wing opening and closing device 600 to maintain the wing 500 folded state, in this case, the blade 500 does not rotate, so the power transmission means 300 ) Does not rotate, and thus, the power relay unit 310 does not rotate, and thus no power is produced from the power generator 320.

따라서, 본 발명은 바람이 기준이상으로 세게 불 때에는 날개(500)가 바람의 영향을 받는 것을 막아서 파손으로부터 예방할 수 있고, 바람이 기준이하일때에는 날개(500)를 활짝 펼쳐서 최대한 전기에너지를 생산할 수 있다.Therefore, the present invention can prevent the blade 500 from being affected by the wind when the wind blows harder than the standard, and can prevent the damage from, and when the wind is less than the standard can spread the blade 500 wide to produce the maximum electrical energy. .

특히, 본 발명은 수직축에 다단으로 설치되므로, 최대한 많은 갯수의 단을 형성토록 하면 회전동력을 훨씬 많이 얻을 수 있으므로 비교적 바람이 약하더라도 전력생산에 차질이 없게 된다.In particular, since the present invention is installed in multiple stages on the vertical axis, it is possible to obtain as much rotational power as possible to form as many stages as possible, so that even if the wind is relatively weak, there is no problem in power production.

결국, 본 발명은 허브를 다수개 결합하여 수직축에 다단으로 날개를 설치할 수 있으며, 동시에 접이식으로 날개를 설계하여 평상시에는 보다 많은 전력을 생산하고 태풍등과 같이 바람이 많이 불 때에는 날개를 접어서 파손을 방지할 수 있는 효과를 제공한다.After all, the present invention can be installed in multiple stages on the vertical axis by combining a plurality of hubs, and at the same time to design the wing to fold to produce more power in normal times, when the wind blows a lot, such as typhoons to break the damage It provides a preventable effect.

비록 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지 만, 본 발명의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 청구의 범위는 본 발명의 진정한 범위내에 속하는 그러한 수정 및 변형을 포함할 것이라고 여겨진다.Although the invention has been described in connection with the preferred embodiments mentioned above, other various modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
