This is made in the wind power generator for generating electricity by using the wind as shown in Figures 4 to 6, a plurality of blade pieces 116 are made by connecting the wing blades 115, each of which has a plurality of rotation radius is provided First rotary blades 111a, 112a, 113a, and 114a and one rotary blade of the plurality of rotary blades 111a, 112a, 113a, and 114a, respectively, are provided to maintain a predetermined interval and are installed to correspond to each other. On the rotating shafts 111 and 114, the second and third rotating shafts 112 and 113 through which the first and fourth rotating shafts 111 and 114 are rotatable and provided with rotary blades on one side thereof, and on the first and fourth rotating shafts 111 and 114, respectively. Also provided in the first and second acceleration cover (120, 121) and the plurality of rotary blades (111a, 114a) to accelerate the flow of the inlet and guide the plurality of blade pieces 116, according to the fluctuation of the wind pressure Wing piece supporting means 130 for elastically supporting the flow of the blade piece 116, and the wing Safety means connected to one side of the piece supporting means 130 and the steel wire 142 to prevent excessively influence of the wind by adjusting the angle of the wing piece 116 during the stone wind, the first 1/2/3 The rotational force is transmitted by a transmission device 150 connected to a fourth and fourth rotation shafts 11, 12, 13, and 14, and a rotation speed, and a shaft 161 coupled to one side of the transmission device 150. A generator 160 for receiving electric power and a shaft 161 of the generator 160 so as to be rotatable, a transmission housing 150a having the transmission 150 therein, and the transmission housing ( Supporting the bottom of the (150a) and the generator 160 is composed of a base frame 170 mounted in a predetermined position.

또한, 상기 날개살(115)은 상기 상기 제1/2/3/4회전축(111,112,113,114)에 연결된 조정관(132)에 회전가능하게 삽입되어, 상기 날개편(116)에 풍력이 전달될 경우 유동적으로 상기 날개살(115) 및 상기 날개편(116)이 동일하게 회전하게 된다.In addition, the blade wings 115 are rotatably inserted into the adjustment pipe 132 connected to the first, second, third, third, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, fourth, and second rotations of the blades 116 are flexible. The blade wings 115 and the blade pieces 116 are rotated in the same manner.

상기 다중 회전날개가 구비된 풍력발전기는 바람을 제1/2가속커버(120,121)에 의해 가속시켜줌과 아울러 개별적으로 회전되는 상기 제1/2/3/4회전날개(111a,112a,113a,114a)의 날개편(116)으로 안내시켜줌으로써 바람의 방향이 일정치 않을 경우에 발생되는 바람에 대한 저항요소와 부하를 감소시킬 수 있어 효과적인 회전력을 얻을 수 있으며, 풍압의 변동에 따라 상기 날개편 지지수단(130)과 안전수단에 의해 상기 제1/2/3/4회전날개(111a,112a,113a,114a)를 탄성적으로 지지함과 아울러, 상기 날개편(116)이 바람의 방향에 수평하게 단계적으로 회전되도록 지지함으로써 풍력의 이용효율을 높일 수 있는 장점이 있었으나, 태풍 및 돌풍 등의 강한 바람으로 인해 날개편(116)이 과도하게 회전될 수 있어 손 상될 우려가 있는 구조상의 문제점과, 회전날개의 구조가 매우 복잡하여 중량이 많이 나가고 제조 비용이 상승하는 문제점이 있었다.The wind power generator having the multi-rotation wings accelerates the wind by the first and second acceleration covers 120 and 121 and separately rotates the first and second and third rotation blades 111a, 112a, 113a, and 114a. By guiding to the wing piece 116 of) can reduce the resistance element and load against the wind generated when the wind direction is not constant to obtain an effective rotational force, support the wing piece according to the fluctuation of wind pressure The first and third rotary vanes 111a, 112a, 113a, and 114a are elastically supported by the means 130 and the safety means, and the wing piece 116 is horizontal to the wind direction. There was an advantage to increase the utilization efficiency of the wind power by being rotated step by step, but due to the strong winds such as typhoons and gusts, the wing piece 116 may be excessively rotated and structural problems that may be damaged, Rotating blade structure is very complicated Over weight is a lot out there was a problem that the manufacturing cost increases.

즉, 날개편(116)은 단순하게 판상의 형상으로 구비되어 상기 제1/2가속커버(120,121)를 통해 강한 바람이 불어올 경우에, 바람의 충격력과 상기 회전날개의 원심력이 동시에 작용되어 상기 날개편(116)이 상기 날개살(115)로부터 분리되는 현상이 발생되었던 것이다.That is, the wing piece 116 is simply provided in a plate-like shape when the strong wind blows through the first and second acceleration covers 120 and 121, the impact force of the wind and the centrifugal force of the rotary blade is applied at the same time The blade piece 116 is separated from the blade (115) has occurred.

따라서, 상기 날개편(116)을 구조적으로 보강하여 풍력에 대한 저항력을 향상시킬 수 있는 별도의 장치가 필요한 실정이다.Therefore, there is a need for a separate device capable of structurally reinforcing the wing piece 116 to improve resistance to wind power.
