Description

풍력 발전기의 날개{Wing of aerogenerator}Wing of aerogenerator

본 발명은 풍력발전기의 날개에 관한 것으로, 더욱 상세하게는 테두리 있는 수평축 풍력발전기의 날개에 관한 것이다.The present invention relates to a blade of a wind turbine, and more particularly to a blade of a horizontal axis wind turbine with a border.

수평축 풍력발전기의 날개의 두께를 얇게 하고 날개의 폭을 넓히고 날개의 수를 늘려 날개의 효율을 극대화하는 것에 관한 것으로, 더욱 상세하게는 날개에 테두리를 형성하여 테두리가 모든 날개를 하나로 동결하여 날개의 부러짐 현상을 방지하고 적은 바람에서도 발전이 용이한 테두리 있는 수평축 풍력발전기의 날개에 관한 것이다.It relates to maximizing the efficiency of the wings by thinning the thickness of the wings of the horizontal axis wind turbine, widening the wings and increasing the number of wings. It relates to a wing of a horizontal axis wind turbine with a rim that prevents breakage and is easy to generate in low winds.

종래의 수평축 풍력발전기의 날개는 강풍에 부러지는 현상 때문에 날개의 두께를 두껍게 하고 폭은 좁게 제작하여 설치되어 있다. 그러나 날개의 폭이 회전 반경에 비해 좁고 날개의 무게 때문에 날개의 숫자도 적어 효율이 떨어지는 단점이 있었다.The wing of the conventional horizontal axis wind turbine is installed by making the thickness of the wing thicker and narrower because of the phenomenon of being broken by the strong wind. However, the width of the wing is narrow compared to the radius of rotation, and due to the weight of the wing has a small number of wings, the efficiency was inferior.

상기와 같이 날개의 폭이 좁아 효율이 떨어지는 단점을 보완하기 위하여 현재 사용 중인 것 중 날개의 길이를 길게 하여 생산되고 있으나, 이 또한 그 두께를 두껍게 하여 무게가 많이 나가는 문제점이 있고, 또한 날개의 길이가 긴 관계로 인 하여 발전기의 기둥을 높게 설치하여야 하는 문제점이 있고 바람이 약하게 부는 곳에는 설치하지 못하는 단점이 있었다.In order to compensate for the disadvantage that the width of the wing is narrow as described above, it is produced by increasing the length of the wing that is currently in use, but this also has a problem that a lot of weight is increased by thickening the thickness, and also the length of the wing Due to the long relationship, there is a problem in that the pillar of the generator must be installed high and the wind cannot be installed in a place where the wind is weak.

본 발명은 수평축 풍력발전기의 날개의 두께를 얇게 하여 무게를 줄이는데 그 목적이 있고, 날개의 폭을 넓게 하는데 그 목적이 있고, 다수의 날개를 설치하여 날개의 회전 반경 내의 풍력을 최대한 회전에너지로 전환하는데 그 목적이 있고, 적은 바람에도 발전을 용이하게 하는데 그 목적이 있고, 태풍 등의 강풍에 날개가 손상되지 않게 하는데 그 목적이 있다.The present invention has a purpose to reduce the weight by thinning the thickness of the blade of the horizontal axis wind power generator, and the purpose is to widen the width of the blade, install a plurality of wings to convert the wind power within the rotation radius of the blade to the maximum rotational energy The purpose is to facilitate the development even in the small wind, and the purpose is to prevent the wings from being damaged by strong winds such as typhoons.

본 발명은 풍력발전기의 날개의 수를 늘리고 폭을 넓혀 효율을 높게 하고 나아가서 날개가 태풍과 같은 강풍에 부러지는 등의 손상을 입지 않게 하는 것에 관한 것으로, 날개에 테두리를 형성하여 테두리가 모든 날개를 하나로 동결함으로서 문제를 해결하며, 가볍고 강한 마그네슘 합금 등의 재질을 이용하여 문제를 해결한다.The present invention relates to increasing the number of wings of the wind turbine and widening the width to increase the efficiency, and further to prevent the blade from being damaged by strong winds such as typhoons. Freezing with one solves the problem, using a light and strong material such as magnesium alloy to solve the problem.

본 발명은 풍력 발전기 날개에 테두리를 형성하여 테두리가 모든 날개를 하나로 동결하여 날개를 고정시키므로 날개의 두께를 얇게 할 수 있어서 무게가 작아지므로, 폭을 넓힐 수 있고, 날개의 수를 늘릴 수 있어서 풍력에너지를 동력에너지로의 전환을 극대화시켜서 바람이 적은 곳에서도 발전이 용이하며, 날개가 테두리 에 고정되어 있으므로 태풍 등의 강풍에 날개가 부러지거나 하는 사고를 미연에 방지할 수 있다.The present invention forms a rim on the wind turbine blades, so that the rim freezes all the wings into one to fix the wings so that the thickness of the wings can be made thinner, so that the weight can be widened, the number of wings can be increased and the wind power By maximizing the conversion of energy into power energy, it is easy to generate power even in a place where there is little wind, and the wing is fixed to the rim to prevent accidents such as wind breaks due to strong winds.

본 발명을 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도1에 도시된 바와 같이 본 발명은 풍력발전기 날개(1)에 테두리(2)를 형성하여, 테두리(2)가 모든 날개(1)를 하나로 결속하는 것이다.As shown in FIG. 1, the present invention forms a rim 2 on the wind turbine blade 1 so that the rim 2 binds all the wings 1 into one.

도1에 도시된 날개(1)는 5개로 구성된 것을 예로 들어 도시한 것이며, 제작과 이동을 원활히 하기 위하여 테두리(2)는 날개(1)의 수로 나뉘며, 날개(1)가 5개 이므로 테두리(2)도 5개로 나뉘게 된다.The wing 1 shown in FIG. 1 is illustrated as an example consisting of five, and in order to facilitate the manufacture and movement, the edge 2 is divided into the number of the wings 1, and since the wings 1 are five, the edge ( 2) will be divided into five.

도2에 도시된 것은 날개와 테두리 묶음 5개에서 1개를 도시한 것이며, 나머지 4개의 날개와 테두리 묶음도 이와 동일하다.2 shows one wing to five and one bundle of borders, and the other four wings and border bundles are the same.

날개의 수로 나눠진 테두리는 날개 1개(4)와 테두리 1개(5)를 용접이나 나사 등으로 동결 하거나, 혹은 주조법으로 날개(4)와 테두리(5)가 일체로 형성되며 .날개 축(3)이 형성된다.The edge divided by the number of wings freezes one wing (4) and one edge (5) by welding or screw, or the wing (4) and the edge (5) are integrally formed by the casting method. ) Is formed.

가볍고 견고한 마그네슘 합금 등을 사용하면 수명이 항구적이다.Light and durable magnesium alloys are used for life.

볼트와 너트를 이용하여 날개(4)의 연결부(7)를 날개 축(3)에 고정시키고 나머지 4개의 동일한 날개와 테두리 묶음도 이와 같이 고정 시킨다. 테두리(5)에 있는 연결부(6)를 날개 축(3)에 연결되어 있는 좌우의 다른 날개(4)와 테두리(5) 묶음의 연결부(6)에 볼트와 너트를 이용하여 결속시킨다.Using bolts and nuts to secure the connection portion 7 of the blade 4 to the blade shaft 3 and the remaining four identical wings and frame bundles are fixed in this way. The connecting portion 6 in the rim 5 is fastened using bolts and nuts to the left and right wings 4 connected to the wing shaft 3 and the connecting portion 6 of the rim 5 bundle.

도2에 도시된 것처럼 테두리(5)의 위치는 꼭 날개(4)의 끝에 설치되어야 하 는 것은 아니며 경우에 따라 날개(4)의 중간지점에 설치 할 수도 있고 테두리(5)의 개수도 2개 이상으로 할 수도 있다.As shown in FIG. 2, the position of the edge 5 is not necessarily installed at the end of the wing 4, and may be installed at the midpoint of the wing 4 in some cases, and the number of the edges 5 is also two. The above can also be done.

도 1은 본 발명에 의한 수평축 풍력발전기 날개에 테를 형성한 것을 도시한 정면도.1 is a front view showing that the frame is formed on the horizontal axis wind turbine blade according to the present invention.

도2는 도1에 도시된 동일한 날개와 테 묶음 5개중 1개를 분리 도시한 확대도Figure 2 is an enlarged view showing one of five of the same wing and frame bundle shown in Figure 1 separated
