본 고안에 따르면, 방향타와 회전 받침대에 의해 정면이 항상 바람의 방향을 향하도록 되어 있는 풍력발전기에서,According to the present invention, in the wind turbine, the front is always facing the direction of the wind by the rudder and the rotating pedestal,

바람을 유입하는 상단 흡입구와 유입된 바람을 가속하여 회전익에 배출하는 내부 배출구가 있고, 본체 내부에는 회전익의 양측에 큰 풀리와, 발전기의 작은 풀리가 벨트로 연결되어 있는 것을 특징으로 하는 풍력발전기가 제공된다.There is an upper inlet for inflowing wind and an inner outlet for accelerating the inflow of wind into the rotor blade, and inside the main body, a large pulley on both sides of the rotor blade and a small pulley of the generator are connected by a belt. Is provided.

이하, 첨부도면에 의하여 본 고안의 구성 및 효과를 설명하면 다음과 같다.Hereinafter, the configuration and effects of the present invention according to the accompanying drawings.

제1도는 본 고안의 측 단면도로, 개방(open)된 하단 흡입구(9)로 들어온 바람은 회전익(2)을 회전시키고 후방 배출구(10)로 배출되며, 또, 상단 흡입구(7)로 흡입된 바람은 내부 배출구(8)로 배출되면서 방향이 바뀌며, 좁아진 배출구로 인해서 유속이 증가되어 회전익을 가속시킨다.1 is a side cross-sectional view of the present invention, the wind entering the open lower inlet (9) rotates the rotor blades 2 and is discharged to the rear outlet (10), and is sucked into the upper inlet (7) The wind changes direction as it is discharged to the internal outlet 8, and the flow rate is increased due to the narrowed outlet to accelerate the rotor blades.

흡입된 바람에 의해 회전하는 회전익은 양 옆에 있는 2개의 큰 풀리(3)를 회전시키고 큰 풀리는 벨트(5)에 의해 연결되어 있는 발전기(6)의 작은 풀리(4)를 회전시켜 전기를 생산한다.The rotor blades rotated by the sucked wind rotate the two large pulleys 3 on both sides and the large pulley rotates the small pulley 4 of the generator 6 connected by the belt 5 to produce electricity. do.

회전익 양쪽의 같은 크기의 풀리는 밸런스를 유지해 주며,The same size pulley on both sides of the rotor maintains balance

각각 발전기를 가동시키기에, 만약 어느 한쪽에 이상이 생기더라도 50%의 발전량은 유지할 수 있도록 되어 있다.Since each generator is operated, 50% of the power generation can be maintained even if an abnormality occurs on either side.

발전기의 보호 캡(14)은 발전기를 외부로부터 보호함과 동시에 배출될 바람을 위쪽으로 보내어, 그 누르는 힘에 의해 풍력발전기 본체(1)가 안정을 유지하도록 한다.The protective cap 14 of the generator protects the generator from the outside and at the same time sends the wind to be discharged upwards, so that the wind turbine body 1 remains stable by the pressing force.

회전 받침대(13)와 방향타(12)의 작용에 의해서 풍력발전기의 정면이 항상 바람의 방향을 향하도록 되어 있어 발전효율을 최대화하며 흡입구와 배출구의 망(net)(11)은 회전익의 파손과 같은 불의의 사고로부터 주위를 보호하는 역할을 한다.The front of the wind turbine is always facing the direction of the wind by the action of the rotary pedestal 13 and the rudder 12 to maximize the power generation efficiency. It protects people from accidents.

상단 흡입구로 흡입되고, 유속이 증가된 바람은 회전익을 가속시켜 발전 효 율을 높여주며, 풍력발전기 본체 내부에 회전익과 동력전달장치, 발전기등의 발전 시스템의 구성 요소가 모두 있어서 설치, 이동, 유지, 보수를 쉽게 할 수 있도록 한다.The wind sucked into the upper inlet, and the flow velocity is increased, accelerates the rotor blades It improves the rate, and there are all components of the power generation system such as rotorcraft, power transmission device, and generator inside the wind turbine body for easy installation, movement, maintenance and repair.
