Description

풍력발전기용 회전체Rotating body for wind power generator
본 발명은 풍력발전기용 회전체에 관한 것으로서 특히 과회전을 방지하면서 유지보수를 용이하게 진행할 수 있는 풍력발전기용 회전체에 관한 것이다.The present invention relates to a rotating body for a wind power generator, and more particularly, to a rotating body for a wind power generator capable of easily performing maintenance while preventing over-rotation.
일반적으로 풍력발전기는 바람에너지를 전기에너지로 바꿔주는 장치로서, 바람에 의해 회전하는 날개에서 회전력을 받아 회전축을 돌려 전기를 생성하며, 풍력발전기는 설치 방법에 따라 수평축 발전기와 수직축 발전기로 분류된다. In general, a wind power generator is a device that converts wind energy into electrical energy, and receives rotational force from a blade rotated by the wind to turn a rotating shaft to generate electricity, and the wind power generator is classified into a horizontal axis generator and a vertical axis generator according to an installation method.
수평축 발전기는 프로펠러 회전 방식으로서 발전 효율은 높으나 유체의 유동 방향에 따라 회전체의 방향을 바꾸어 주어야 하며, 유체의 유속에 따라 날개의 각도를 바꾸어 주는 장치가 필요하다. 또한, 회전체의 축이 회전체의 반지름보다 높은 곳에 위치해야 하므로, 높은 곳에 위치한 회전축과 발전부를 연결하기 위해 발전부를 회전축과 같은 높이에 설치하거나, 수평 회전력을 수직 회전력으로 전환하는 장치를 설치하기도 한다. 전자는 유체의 강한 흐름에 의해 기구적 손상이 발생할 수 있으며, 유지보수도 쉽지 않다는 문제가 있으며, 후자는 수평 회전력을 수직 회전력으로 전환하는 과정에서 에너지 손실이 생길 수 있다. The horizontal axis generator is a propeller rotation method and has high power generation efficiency, but the direction of the rotating body must be changed according to the flow direction of the fluid, and a device for changing the angle of the blade according to the flow rate of the fluid is required. In addition, since the axis of the rotating body must be located at a higher place than the radius of the rotating body, the power generation unit is installed at the same height as the rotating shaft to connect the rotating shaft located at a high place and the power generation unit, or a device for converting horizontal rotational force into vertical rotational force is installed. do. The former may cause mechanical damage due to the strong flow of fluid, and there is a problem that maintenance is not easy, and the latter may cause energy loss in the process of converting horizontal rotational force into vertical rotational force.
이러한 수평축 발전기의 문제점으로 인해, 최근 많은 수직축 발전기들이 개발되고 있으나, 수직으로 배치된 날개들이 고정 설치되어 있으므로 다수 개의 날개 중 일부 날개가 바람에 의한 마찰을 받는 상태에서 회전하게 되는바 회전력이 약화되고 발전량을 상승시키기지 못한다는 문제가 있다. Due to the problem of such a horizontal axis generator, many vertical axis generators have been developed recently, but since the blades arranged vertically are fixedly installed, some of the blades rotate in a state where some of the blades are subjected to friction by the wind, and the rotational force is weakened There is a problem that the power generation cannot be increased.
상술한 수직축 발전기의 문제를 해결하고자 본 출원인은 대한민국 등록특허 제10-1684845호(이하, '인용발명'이라 함)에 바람에 따라 각각의 날개가 외측으로 열린 상태를 이루거나 닫힌 상태를 이룰 수 있는 회전체를 제안하고 있다. In order to solve the problem of the above-mentioned vertical axis generator, the present applicant has disclosed in Korean Patent No. 10-1684845 (hereinafter referred to as 'cited invention') that each wing can form an outwardly open state or a closed state according to the wind. A rotating body is proposed.
인용발명은 회전체가 바람에 의한 마찰에 따른 저항력을 적게 받을 수 있는바 회전력이 상승된다는 효과를 얻을 수 있다. 그러나, 인용발명은 이로 인해 회전체의 과회전이 발생될 수 있으며, 유지보수를 위해 회전체가 정지된 상태를 이루도록 하기 어렵다는 문제가 발생된다.The cited invention can obtain the effect that the rotational force is increased as the rotating body can receive less resistance due to friction caused by wind. However, the cited invention may cause over-rotation of the rotating body due to this, and there is a problem in that it is difficult to achieve a stopped state for the rotating body for maintenance.

When the wind blows toward the rotor for a wind power generator according to the present invention as described above, the blade plate 500 forms an open state to the outside of the rotation plate 300 by the wind, or forms a closed state inside the rotation plate 300 , the rotation plate (300) is rotated. The present invention that operates in this way includes a configuration that can adjust the speed.
즉, 회전판(300)은 도 1 및 도 2에 도시된 바와 같이 회전축(200)과 인접한 내주연을 따라 상방으로 돌출된 조절턱(310)이 형성되며, 회전축(200)은 길이방향을 따라 내측에 제1 조절대(600)가 구비되고 조절턱(310)과 인접한 지점에 제1 이동홀(210)이 관통형성된다. 그리고, 제1 조절대(600)는 회전축(200)의 내측에서 유압 등을 통해 상하방향으로 이동되며, 이러한 제1 조절대(600)에는 제1 이동홀(210)을 관통하며 조절턱(310)의 상측에 위치하도록 속도조절대(610)가 형성된다. That is, the rotating plate 300 has an adjustment jaw 310 protruding upward along the inner periphery adjacent to the rotating shaft 200 as shown in FIGS. 1 and 2 , and the rotating shaft 200 is inside along the longitudinal direction.

The first moving hole 210 may be formed through a predetermined length along the longitudinal direction of the rotating shaft 200 so that the speed adjusting bar 610 can be moved up and down together with the movement of the first adjusting bar 600 . For example, the upper end of the control jaw 310 may be formed through a point corresponding to the position to form a long oval in the vertical direction. That is, the speed adjusting bar 610 is in contact with the adjusting jaw 310 as the first adjusting bar 600 is moved downward as shown in FIGS. 3 and 4 and can reduce the speed of the rotating plate 300 . .
또한, 속도조절대(610)는 일자 형태로 형성되어 조절턱(310)과 맞닿을 수 있으나, 도 1 내지 도 4에 도시된 바와 같이 단부가 하방으로 개방된 'ㄷ'자 형태로 형성되어, 제1 조절대(600)가 하방으로 이동시, 조절턱(310)이 속도조절대(610)의 단부의 내측에 위치하게 되는바, 속도조절대(610)는 보다 안정적으로 조절턱(310)과 맞닿을 수 있다.
