상기 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

풍력에 의해 회전되는 날개와, 이 날개의 회전축 및 이와 연결되어 회전구동됨에 따라 전기를 발생하는 발전기로 이루어진 풍력 발전기에 있어서,In the wind generator comprising a blade that is rotated by the wind, and a rotary shaft of the blade and a generator that is connected to the rotary drive to generate electricity,

상기 메인 날개의 후측 둘레에 다수개의 보조 날개들을 겹치지 않도록 겹겹이 분산 배치하고, 사이 보조 날개들의 회전축들을 상기 메인 회전축과 일방향 회전기어로 연결하여 회전력을 집속하도록 한 것을 특징으로 한다.A plurality of auxiliary blades are arranged to be distributed so as not to overlap a plurality of auxiliary blades around the rear side of the main blade, and the rotation axes of the auxiliary blades between the main rotating shaft and the one-way rotary gear are configured to focus rotational force.

또한 상기 메인 날개 및 보조날개들의 둘레에 원통형의 바람안내통을 구비한 것을 특징으로 한다.In addition, characterized in that provided with a cylindrical wind guide around the main wing and auxiliary wings.

이하, 본 발명을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings the present invention will be described in detail.

도 2는 본 발명에 따른 풍력 발전기의 날개 배치상태를 나타낸 정면도이고, 도 3은 본 발명에 따른 풍력 발전기의 날개 배치상태를 나타낸 측면도이다.2 is a front view showing a blade arrangement of the wind generator according to the present invention, Figure 3 is a side view showing a blade arrangement of the wind generator according to the present invention.

상기의 도면들에서 보는 바와 같이 풍력 발전기의 메인 날개(10)가 설치되고, 그 메인 날개(10)의 중심부에는 회전축(11)이 설치되어 있다. 이 메인 날개(10)의 외부에는 바람을 안내하는 원통형의 바람안내통(20)이 설치되어 있으며, 이 바람안내통(20)의 입구부는 외부로 벌어져 많은 바람을 받아들일 수 있도록 나팔형태와 같이 넓게 확관된 집풍가이드(21)가 형성 되어 있다. 이 바람안내통(20)은 풍력 발전기의 지주(P)와 연결되어 있으며, 메인 회전축(11)은 도면에 도시되지 않은 발전기를 구동시키는 동력전달장치(14)와 연결되어 있다As shown in the drawings, the main blade 10 of the wind generator is installed, the rotating shaft 11 is installed in the center of the main blade 10. The outside of the main wing 10 is provided with a cylindrical wind guide (20) for guiding the wind, the inlet of the wind guide (20) is opened to the outside to receive a lot of wind like a trumpet type The wide wind collecting guide 21 is formed. The wind guide tube 20 is connected to the prop (P) of the wind generator, the main rotary shaft 11 is connected to the power transmission device 14 for driving the generator not shown in the figure.

또 메인 날개(10)의 후측에는 다수개의 보조날개(100a∼100n)들이 서로 교호되게 설치되어 있으며, 가 보조날개(100a∼100n)들의 중심부에는 회전축(110a∼110n)들이 설치되어 각 보조날개(100a∼100n)들과 함께 회전되도록 되어 있으며, 이 회전축(110a∼110n)들은 지지대로 바람안내통(20)에 고정설치되어있다.In addition, a plurality of auxiliary wings (100a to 100n) are alternately installed on the rear side of the main blade (10), the rotary shafts (110a to 110n) are installed in the center of the auxiliary wings (100a to 100n) each auxiliary wing ( It is to be rotated together with the 100a ~ 100n, these rotary shafts (110a ~ 110n) are fixed to the wind guide tube 20 as a support.

각 회전축(110a∼110n)들은 단부에 일방향 기어(130a∼130n)들이 설치되어 있으며, 이들은 또한 메인 회전축(11)에 베벨기어와 같은 동력전달기어(140∼140n)로 연결된다.Each of the rotary shafts 110a to 110n is provided with one-way gears 130a to 130n at the ends thereof, which are also connected to the main rotary shaft 11 by a power transmission gear 140 to 140n such as a bevel gear.

일방향 기어(130a∼130n)는 자전거의 래칫기어와 같이 일방향으로는 회전축(110a∼110n)과 함께 회전되지만 그 반대쪽으로는 헛돌게 구성되어 있어 바람에 의해 보조날개(100a∼100n)가 회전될 때에는 동력을 메인 회전축(11)에 전달하지만 메인 회전축(11)의 회전속도가 빠르게 되면 그 회전이 보조날개(100a∼100n)들의 회전축(110a∼110n)에 영향을 미치지 못하도록 되어 있다.The one-way gears 130a to 130n rotate together with the rotational shafts 110a to 110n in one direction like the ratchet gears of the bicycle, but are configured in an opposite direction so that the auxiliary blades 100a to 100n are rotated by the wind. When the power is transmitted to the main rotary shaft 11 but the rotation speed of the main rotary shaft 11 is increased, the rotation does not affect the rotary shafts 110a to 110n of the auxiliary wings 100a to 100n.

이러한 구조로된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention having such a structure as follows.

먼저 바람이 불게 되면 바람안내통(20)의 입구부에 형성된 집풍가이드(21)에 의해 많은 바람이 바람안내통(20)의 내부로 유입되게 되며 바람안내통(20)으로 안내되어 유입된 바람은 그 내부룰 빠른 속도로 통과하게 된다. 이 바람에 의해 메인 날개(10)가 회전하게 되고 동시에 메인 회전축(11)이 회전하게 된다.First, when the wind blows, a lot of wind is introduced into the inside of the wind guide tube 20 by the wind guide guide 21 formed at the inlet of the wind guide tube 20 and the wind guided to the wind guide tube 20 Passes quickly through its internals. This wind causes the main blade 10 to rotate and at the same time the main rotary shaft 11 rotates.

메인 날개(10)를 회전시키는데 기여한 바람이나 메인 날개(10)를 회전시키는데 기여하지 못하고 그대로 통과한 바람 모두 메인 날개(10)를 통과한 후에는 그 후측에 설치된 보조날개(100a∼100n)과 마주치게 되어 이들을 회전시키게 되며, 이들을 회전시키는데 기여하거나 또는 기여하지 못한 바람은 다시 그 후측에 설치된 또다른 보조날개(100a∼100n)들을 회전시키는데 기여하게 된다. 이 작용은 최종적으로 설치된 보조날개(100n)를 회전시킨 후 버려지게 된다.After both the wind that contributed to the rotation of the main blade 10 or the wind that passes through the main blade 10 without passing the main blade 10 passes through the main blade 10, it faces the auxiliary wings 100a to 100n installed on the rear side. And the wind that contributes to or does not contribute to the rotation of them, again contributes to the rotation of the other auxiliary wings (100a to 100n) installed on the rear side. This action is discarded after rotating the auxiliary blade 100n finally installed.

이와 같이 보조날개(100a∼100n)들이 회전하게 되면 각 보조날개(100a∼100n)들은 각각의 회전축(110a∼110n)들을 회전시키게 되고 이는 각 회전축(110a∼110n)의 후측에 설치된 일방향 기어(130a∼130n)들을 회전시키게 되고 동력전달기어(140a∼140n)를 통해 메인 회전축(11)의 회전에 기여를 하게 된다.As the auxiliary blades 100a to 100n rotate as described above, each of the auxiliary blades 100a to 100n rotates the respective rotation shafts 110a to 110n, which is a one-way gear 130a installed on the rear side of each of the rotation shafts 110a to 110n. And rotate the ˜130n and contribute to the rotation of the main rotating shaft 11 through the power transmission gears 140a to 140n.

이상에서 살펴본 바와 같이 본 발명은 메인 날개의 뒤로 다수개의 보조날개들이 겹겹이 분산 배치되어 있기 때문에 메인 날개를 회전시키는데 기여를 하거나 또는 그렇지 않은 바람이 분산배치한 보조날개들을 거치면서 지나가도록 되어 있고 또 각 보조날개들의 회전축들이 일방향 기어나 동력전달기어를 통해 메인축을 회전시키는데 일조를 하기 때문에 풍량이 적은 날에도 발전을 실시할 수 있으며, 또 그냥 버려지는 풍력 에너지 없이 발전에 활용함에 따라 효율적인 풍력발전을 할 수 있는 효과가 있다. 또한 이러한 효과로 인하여 본 발명은 풍량이 적은 환경에서도 풍력발전을 실시할 수 있는 효과가 있다.As described above, in the present invention, since a plurality of auxiliary wings are arranged behind the main blades, the auxiliary blades contribute to the rotation of the main blades or pass through the auxiliary wings that are not arranged by the wind. The rotating shafts of the auxiliary blades help to rotate the main shaft through one-way gear or power transmission gear, so it can generate power even on days with low wind volume. It can be effective. In addition, the present invention has the effect that can be carried out wind power in an environment with a small amount of wind.
