Description

Ｖ-형 수직축 풍력발전기Ｖ-type vertical axis wind power generator
본 발명은 풍력에 의해 수직축을 중심으로 회전하여 전력을 생산하는 수직축 풍력 발전기에 관한 것으로, 더욱 상세하게는 기존의 수직축 풍력 발전기보다 타워의 크기를 최소화하여 편심에 의한 진동을 줄여 구조적으로 안정하도록 개선하였고, 제작 및 운반이 편리하면서 무게를 최소화하여 도심 지역의 건물 옥상 설치에 가장 적합한 신개념 V-형 수직축 풍력 발전기에 관한 것이다.The present invention relates to a vertical axis wind power generator for generating power by rotating about a vertical axis by wind power, and more specifically, to minimize the size of the tower than conventional vertical axis wind generators to improve the structural stability by reducing vibration caused by eccentricity It is a new concept V-type vertical axis wind power generator that is most suitable for rooftop installation of buildings in urban areas by minimizing weight while being easy to manufacture and transport.
수직축 풍력 발전기는 수평축 발전기에 비해 풍향 변화에 상관없는 안정적인 효율과, 블레이드를 고정하는 암 및 허브구조를 매우 안정적이고 안전하게 설계할 수 있는 점 등의 다양한 장점이 있다. 따라서 수직축 풍력 발전기는 설계에 따라 2m/s 이하(시동 풍속 0.8~1.5m/s)의 낮은 풍속에서도 효율적이면서 안전한 전력발전이 가능하다.The vertical axis wind power generator has various advantages, such as stable efficiency regardless of the wind direction change, and the arm and hub structure for fixing the blade can be designed very stably and safely compared to the horizontal axis generator. Therefore, vertical axis wind power generators can efficiently and safely generate power even at low wind speeds of less than 2m / s (starting speed 0.8 ~ 1.5m / s).
하지만, 이러한 장점에도 불구하고 기존의 수직축 풍력 발전기는 회전축을 중심으로 블레이드가 하방으로 내려와야 하기 때문에 블레이드 길이방향의 질량분포 불균형과 각 블레이드의 무게 차이로 인해 발생하는 편심에 의한 진동 방지를 위한 강건한 구조설계 및 제작이 요구되어 상대적으로 가격이 비싸지는 단점이 있다.However, in spite of these advantages, the conventional vertical axis wind power generator is required to lower the blades around the rotation axis, so it is robust to prevent the vibration caused by the eccentric mass distribution in the longitudinal direction of the blade and the difference in the weight of each blade. There is a disadvantage that the price is relatively expensive because the structural design and manufacturing is required.
도 1에는 통상의 수직축 풍력발전기의 사시도가 도시되어 있다.1 is a perspective view of a conventional vertical axis wind turbine.
일반적인 수직축 풍력 발전기의 구성은 도시된 바와 같이, 블레이드(1), 블레이드를 지지하는 암(arm, 2), 허브(3)에 의해 암(2)과 결합되는 마스트(Mast) 형태의 회전축(4)을 포함하여 이루어지는 회전 중심부와 및 베어링 연결 없이 회전 중심부와 직접연결 또는 증속을 위해 벨트나 기어박스로 연결 가능한 발전기(5)로 이루어진다. 상기 회전 중심부에는 유동 흐름에 허브하우징 효과를 더하기 위해 실린더 형태로 형성되어 회전 중심부를 감싸는 형태로 구비되는 외부 덮개(6)가 추가로 구비될 수 있다. 또한, 일반적으로 암(2) 및 회전축(4)은 금속재 또는 복합재의 재질로 형성된다.The configuration of a general vertical axis wind generator is a blade (1), an arm (2) for supporting the blade, as shown in the shaft (Mast) rotary shaft (4) coupled to the arm (2) by the hub (3) And a generator 5 which can be connected to a belt or gearbox for direct connection or speed-up with the rotating center without bearing connection and the rotating center. The rotating center may be further provided with an outer cover 6 formed in a cylindrical shape to surround the rotating center to add a hub housing effect to the flow flow. In addition, the arm 2 and the rotating shaft 4 is generally formed of a metal material or a composite material.
종래의 풍력 발전기는 회전축(4)과 블레이드(1)를 연결하는 암(2)의 구성이 지면에 수평하게 구성되기 때문에 블레이드(1) 회전 공간을 많이 차지하며, 블레이드(1)는 지면에 수직한 상하 길이 방향으로 배치되기 때문에 회전축(타워)이 길어지는 문제점이 있었다.The conventional wind generator occupies a lot of rotation space of the blade (1) because the configuration of the arm (2) connecting the rotating shaft (4) and the blade (1) is horizontal to the ground, the blade (1) is perpendicular to the ground Since it is disposed in one vertical length direction, there was a problem that the rotating shaft (tower) is long.
이에 따라 발전기 공간을 적게 차지하며, 블레이드의 무게 차이로 인해 발생하는 편심에 의한 진동의 방지를 위해 타워의 길이를 낮게 설계하여 진동을 최소화하고, 조립 및 분해가 용이하면서도 충분한 강도를 가질 수 있어 대량 생산이 용이하며, 제작단가가 저렴하고, 유지보수 비용이 적은 수직축 풍력 발전기의 개발이 요구된다.Accordingly, it takes up less space for the generator and minimizes the vibration by designing the tower length to prevent vibration caused by eccentricity caused by the weight difference of the blades, and it is easy to assemble and disassemble and has sufficient strength. It is required to develop a vertical axis wind generator that is easy to produce, low in production cost, and low in maintenance cost.
