그리고 상기 회전축(130)에는 상기 전·후방블레이드(140,150) 사이에 요크(201,yoke)와 여자코일(202) 및 유도자(203, 또는 회전자)로 구성된 전자석체(200)가 삽입 설치되어 있다.In addition, an electromagnet 200 composed of a yoke 201 and a yoke, an excitation coil 202 and an inductor 203 or a rotor is inserted between the front and rear blades 140 and 150. .
상기 전자석체(200)는 고정브라케트(204)에 의해 상기 몸체프레임(120)에 고정 설치되고, 상기 회전축(130)은 상기 전자석체(200)에 회전 가능하도록 삽입 설치되는 구조를 이루게 된다.The electromagnet 200 is fixed to the body frame 120 by a fixed bracket 204, the rotating shaft 130 is formed to be inserted into the electromagnet 200 so as to be rotatable.
상기 유도자(203)의 외측으로는 회전이 자유롭게 되면서 상기 유도자(203)에 전류가 흐르게 될 때 형성되는 자력에 의해 그 회전력이 제어될 수 있도록 하는 회전자드럼(210)이 설치 구비되고, 상기 회전자드럼(210)은 원통형상의 ㄱ자 형상으로 되면서 그 단부에는 상기 회전축(130)에 베어링수단(220)으로 삽입 설치되어 회전이 자유롭게 되도록 하는 드럼회전축(211)이 연결 설치되는 구조로 되어 있다. Rotor drum 210 is provided to the outside of the inductor 203 so that the rotational force can be controlled by a magnetic force generated when the current flows through the inductor 203, the rotation The electronic drum 210 has a cylindrical L-shape and a drum rotating shaft 211 is inserted into the rotating shaft 130 to be inserted into the bearing means 220 so as to be freely rotated.
그리고 상기 보조블레이드(180)는 상기 드럼회전축(211)에 연결 고정되어 상기 회전축(130)과는 별도로 풍력에 의해 자유롭게 회전될 수 있게 된다.In addition, the auxiliary blade 180 is connected to the drum rotation shaft 211 and is fixed to be freely rotated by wind power separately from the rotation shaft 130.
또한 상기 드럼회전축(211)의 단부에는 상기 보조블레이드(180)가 견고하게 고정 지지될 수 있도록 하는 지지브라케트(212)가 설치 구비되어 있다.In addition, the end of the drum rotating shaft 211 is provided with a support bracket 212 to be firmly fixed to the auxiliary blade 180.
그리고 상기 전자석체(200)는 상기 보조블레이드(180)의 회전수를 인식할 수 있는 센서수단(미도시)에 의해 상기 축전장치로부터 전류가 공급될 수 있도록 연결 되어 있다. 즉, 상기 보조블레이드(180)의 회전수가 설정값 이상으로 감지되면 이를 제어부(미도시)에 신호를 보내고 제어부는 센서의 신호에 의해 상기 축전장치로부터 상기 전자석체(200)로 전류를 공급하게 된다.In addition, the electromagnet 200 is connected so that a current can be supplied from the power storage device by a sensor means (not shown) capable of recognizing the rotational speed of the auxiliary blade 180.

상기와 같은 구조로 이루어진 본 발명의 보조블레이드를 갖는 풍력발전기(100)가 작동되는 방법을 살펴보면 다음과 같다.Looking at the method of operating the wind power generator 100 having the auxiliary blade of the present invention having the above structure as follows.
우선, 통상적으로 바람이 불게 되면 상기 전방블레이드(140)와 상기 후방블레이드(150) 및 이들 사이에 설치되어 있는 상기 보조블레이드(180)가 동시에 회전되고 이로 인하여 상기 회전축(130)이 회전된다.First, when the wind blows, the front blade 140 and the rear blade 150 and the auxiliary blade 180 installed therebetween are rotated at the same time, thereby rotating the rotating shaft 130.
이어 상기 회전축(130)의 회전력에 의해 상기 발전장치(190)에서 전력이 생산되면서 축전장치나 각종 제어부로 전력을 공급하게 된다.Subsequently, power is produced by the power generation device 190 by the rotational force of the rotation shaft 130 to supply power to the power storage device or various control units.
일반적으로 풍력에 의해 회전되는 상기 전방블레이드(140)의 직후방에는 몸체프레임(120)의 주위에 와류가 발생되어 상기 후방블레이드(150)의 회전을 방해할 뿐 아니라 상기 와류의 발생으로 전방블레이드(140)를 통과한 공기가 후방블레이드(150)까지 신속하게 전달되지 아니하고 상기 몸체프레임(120) 주변에 머물게 되어(부압의 발생), 결구 전방블레이드(140)의 회전을 방해하여 발전효율을 저하시키는 원인으로 되어 있는바, 본 발명은 상기 보조블레이드(180)가 풍력에 의해 회전되면서 상기 전방블레이드(140)의 직후방에 형성되는 부압을 후방으로 신속하게 불어(송풍)줌으로써 상기 전방블레이드(140)의 후방에 형성되는 부압이 제거되고 이로 인해 그 회전력이 향상될 수 있고 이와 동시에 후방에 위치하고 있는 상기 후방블레이드(150)로 송풍력이 추가로 전달되어 그 회전력 또한 향상되어, 결국에는 상기 전방블레이드(140)와 상기 후방블레이드(150)의 회전력이 향상으로 인해 상기 발전장치(190)의 발전 효율을 향상시킬 수 있게 된다. In general, immediately after the front blade 140 rotated by wind power, vortices are generated around the body frame 120 to hinder the rotation of the rear blade 150 as well as the front blades due to the generation of the vortex. The air passing through the 140 is not quickly delivered to the rear blade 150 and stays around the body frame 120 (the occurrence of negative pressure), which hinders the rotation of the front blade 140, thereby lowering the power generation efficiency. As a cause, the present invention is the front blade 140 by rapidly blowing (blowing) the negative pressure formed immediately after the front blade 140 while the auxiliary blade 180 is rotated by the wind (back). The negative pressure formed at the rear of the can be eliminated and thereby the rotational force can be improved and at the same time the blowing force to the rear blade 150 located in the rear additionally Since the rotational force is also improved, the rotational force of the front blade 140 and the rear blade 150 may be improved, thereby improving power generation efficiency of the power generator 190.
그리고 강풍이 불어오는 경우, 상기 센서수단에 의해 상기 보조블레이드(180)의 회전수가 설정값 이상으로 회전되는 것을 감지할 수 있도록 함으로써 상기 제어부를 통해 상기 전자석체(200)로 전류가 자동으로 공급된다.When the strong wind blows, the current is automatically supplied to the electromagnet 200 through the control unit by allowing the sensor unit to detect that the rotation speed of the auxiliary blade 180 is rotated above a set value. .
그러면 상기 여자코일(202)과 유도자(203)에 의해 상기 회전자드럼(210)에 자기력이 형성되고 이 자기력에 의해 상기 회전자드럼(210)의 회전력이 제어됨으로써 이와 연결된 상기 보조블레이드(180)의 회전력이 감소하게 된다.Then, a magnetic force is formed on the rotor drum 210 by the excitation coil 202 and the inductor 203, and the auxiliary blade 180 connected thereto by controlling the rotational force of the rotor drum 210 by the magnetic force. The rotational force of is reduced.
상기 보조블레이드(180)의 회전력이 감소하게 되면 상기 전방블레이드(140)의 직후방에 다시 부압이 형성되고 이 부압에 의해 상기 전방블레이드(140)와 상기 후방블레이드(150)의 회전력이 점차 감소하게 된다.When the rotational force of the auxiliary blade 180 is reduced, negative pressure is formed again immediately after the front blade 140, and the rotational force of the front blade 140 and the rear blade 150 is gradually decreased by the negative pressure. do.
따라서 강풍에 의해 지나치게 상기 전방블레이드(140)와 상기 후방블레이드(150)가 회전되는 것을 막아 그 내구성을 향상시킬 수 있게 된다.Therefore, the front blade 140 and the rear blade 150 are prevented from being excessively rotated by the strong wind, thereby improving durability.
이와 같은 구조의 상기 풍력발전기(100)는 상기 전방블레이드(140)와 상기 후방블레이드(150)의 회전 날개수를 동일하게 구성하고, 또 상기 보조블레이드(180)의 회전 날개 수는 상기 전방블레이드(140)와 상기 후방블레이드(150)의 회전 날개수를 합한 날개수와 동일하게 구성하는 것이 가장 효율적이다.The wind generator 100 having such a structure has the same number of rotation blades of the front blade 140 and the rear blade 150, and the number of rotation blades of the auxiliary blade 180 is the front blade ( It is most efficient to configure the same number of blades that the number of the rotating blades 140 and the rear blades 150 are added together.
또한 상기 보조블레이드(180)의 크기는 상기 전방블레이드(140)와 상기 후방블레이드(150)의 크기보다 더 크게 형성되도록 하는 것이 바람직하다.In addition, the size of the auxiliary blade 180 is preferably larger than the size of the front blade 140 and the rear blade 150.
따라서 본 발명의 보조블레이드를 갖는 풍력발전기는 바람의 힘에 의해 회전되는 전후방 블레이드의 사이에 보조 블레이드를 더 구비하여 상기 보조블레이드의 회전력이 후방 블레이드에 송풍력으로 작용되도록 함으로써 동일한 바람의 세기에도 더욱 증강된 회전력을 얻어 전력 생산 효율을 더욱 높여줄 수 있는 효과를 얻게 된다.Therefore, the wind power generator having the auxiliary blade of the present invention further includes an auxiliary blade between the front and rear blades rotated by the force of the wind so that the rotational force of the auxiliary blade acts as a blowing force on the rear blade, so that even in the same wind strength. The increased rotational force is obtained to further increase the power production efficiency.
또한, 태풍과 같은 강풍시에는 보조블레이드의 회전력을 전자적으로 제어하여 전후방 블레이드의 회전력을 통제할 수 있도록 함으로써 이들이 강풍 등에 파손되는 것을 막아 내구성을 향상시킬 수 있는 장점이 있다.In addition, in a strong wind such as a typhoon, by controlling the rotational force of the auxiliary blade electronically to control the rotational force of the front and rear blades there is an advantage to improve the durability by preventing them from being damaged in strong winds.
