본 발명은 전자기유도 원리를 적용하여 풍력발전장치의 회전날개에 얼음이 얼어붙는 것을 미리 차단하거나 제거하는 장치에 관한 기술이다.The present invention relates to an apparatus for blocking or removing freezing of ice on a rotating blade of a wind power generator by applying an electromagnetic induction principle.

기존 발명은 풍력발전장의 회전날개에 이미 얼어붙은 얼음을 제거하거나 얼음이 미리 차단하는 장치들은 비용이 많이 들고 유지비용이 많이 들지만, 본 발명은 비용이 적게 들고 유지비가 거의 들지 않는 장점이 있다.The existing invention is advantageous in that the apparatus for removing the ice that has already frozen in the rotary blades of the wind turbine or the apparatus for blocking the ice in advance is expensive and the maintenance cost is high, but the present invention has a low cost and little maintenance cost.

풍력발전장치의 회전축에 코일을 감고 회전축 주위에 자석을 설치하여 전자기 유도원리에 의해 전기가 발생하면 발생된 전기를 이용하여 열선을 열기를 이용하여 얼음이 얼어붙는 것을 미리 차단하거나 제거하는 장치이다.When a coil is wound around the rotating shaft of a wind power generator and a magnet is installed around the rotating shaft to generate electricity by electromagnetic induction principle, it is a device for blocking or removing ice from freezing by using heat generated by electricity generated.

본 발명에 따르면 전자기 유도원리에 의해 전기가 발생하도록 풍력발전장치 회전축에 코일을 감고 회전축 주위에 자석을 배치하여 베어링과 기어장치가 전혀 없이 발생된 전기를 회전날개에 설치된 열선에 전기를 공급하는 장치를 만들 수 있다.According to the present invention, a coil is wound around a rotary shaft of a wind power generator so that electricity is generated by an electromagnetic induction principle, and a magnet is disposed around the rotary shaft to supply electricity generated by the bearing and the gear device to the heater .

거의 모든 풍력발전장치에 사용이 가능하며 전자기 유도원리에 의해 전기를 만들기 때문에 마찰력을 없고 설치비가 적게 들고 고장이 적게 나며 수리가 간편하다. 또한, 베어링이나 기어가 전혀 없고 각종 기계장치가 거의 없기 때문에 고장이 거의 없으며 오랫동안 사용이 가능한 장점이 있다.It can be used in almost all wind power generation devices. It makes electricity by electromagnetic induction principle, so there is no friction, installation cost is low, trouble is less, and repair is easy. In addition, since there are no bearings or gears, and there are few mechanical devices, there is little trouble and there is an advantage that it can be used for a long time.

본 발명의 풍력발전장치에 대한 얼음방지장치의 구성에 있어서,In the configuration of the ice prevention device for the wind power generator of the present invention,

대표도면과 도면 1에서 기존 거의 모든 풍력발전장치의 회전축(4)에 코일(6)을 감고 코일(6) 주위에 전자기유도원리에 의해 전기가 발생하도록 자석(5)을 설치한다. 회전날개(3)에 열을 발생하는 열선(9)을 설치한다. 회전축(4)은 회전날개(3)가 회전하면 같이 회전하고 회전축(4)에 감긴 코일(6)도 같이 회전하고 자석(5)은 고정되어 있기 때문에, 고정된 자석(5)과 회전하는 코일(6)에서 전자기유도원리(10)에 의해 전기가 발생한다. 발생된 전기는 축전기(7)에 충전하고 충전된 전기를 배터리(8)에 공급한다. 배터리(8)를 통해 열선(9)에 전기를 공급하여 열선에서 열을 발생시켜 회전날개(3)에 얼음이 생기는 것을 방지하거나 얼음을 제거할 수 있게 된다.In the representative drawing and FIG. 1, the coils 6 are wound around the rotary shaft 4 of almost all conventional wind power generators, and the magnets 5 are installed around the coils 6 to generate electricity by the electromagnetic induction principle. A heat ray (9) generating heat is provided in the rotary vane (3). Since the rotary shaft 4 rotates together with the rotary vane 3 and the coil 6 wound on the rotary shaft 4 rotates together and the magnet 5 is fixed, (6), electricity is generated by the electromagnetic induction principle (10). The generated electricity charges the capacitor (7) and supplies the charged electricity to the battery (8). Electricity is supplied to the heat ray 9 through the battery 8 to generate heat in the heat ray to prevent ice from being generated in the rotary blade 3 or to remove ice.

본 발명은 회전날개(3)와 회전축(4)에 코일(6)과 축전기(7)과 배터리(8)와 열선(9)이 같이 붙어 있어 회전을 같이하는 시스템이며, 각종 베어링과 기어장치가 필요가 없이 전기를 만들어 집적 열선에 전기를 공급하는 시스템이므로, 지속적으로 회전날개에 열을 공급하므로 얼음이 생기지 않도록 하고 고장이 거의 없으므로 극한의 극지방이나 고산지대에서도 사용이 가능한 장점이 있다.The present invention is a system in which a coil 6, a capacitor 7, a battery 8 and a heat wire 9 are attached to a rotating blade 3 and a rotating shaft 4 to rotate together and various bearings and gear devices Since it is a system that supplies electricity to the integrated hot wire by making electricity without need, it is advantageous that it can be used in extreme polar regions and high mountainous regions because it continuously supplies heat to the rotary blades so that ice does not occur and there is no trouble.

도면 2에서 기존 거의 모든 풍력발전장치의 회전축(11)에 코일을 감지 않고 회전날개(14)에 코일(13)을 감고 코일(13)을 마주보며 전자기유도원리에 의해 전기가 발생하도록 자석(12)을 설치한다. 회전날개(14)에 열을 발생하는 열선(17)과 축전기(15)와 배터리(16)를 설치한다. 회전날개(14)가 회전하면 회전날개(14)에 감긴 코일(13)도 같이 회전하고 자석(12)은 고정되어 있기 때문에, 고정된 자석(12)과 회전하는 코일(13)에서 전자기유도원리(18)에 의해 전기가 발생한다. 발생된 전기는 축전기(15)에 충전하고 충전된 전기를 배터리(16)에 공급한다. 배터리(16)를 통해 열선(17)에 전기를 공급하여 열선에서 열을 발생시켜 회전날개(14)에 얼음이 생기는 것을 방지하거나 얼음을 제거할 수 있게 된다.In FIG. 2, the coil 13 is wound around the rotary vane 14 without facing the rotary shaft 11 of the conventional wind turbine, and the coil 13 is faced to the magnets 12 ). A heat ray (17), a capacitor (15), and a battery (16) are installed to generate heat in the rotary vane (14). When the rotary vane 14 rotates, the coil 13 wound on the rotary vane 14 also rotates and the magnet 12 is fixed. Therefore, the electromagnetic induction principle is established in the fixed magnet 12 and the rotating coil 13, (18). The generated electricity charges the capacitor (15) and supplies the charged electricity to the battery (16). Electricity is supplied to the hot wire 17 through the battery 16 to generate heat in the hot wire to prevent ice from being generated in the rotary vane 14 or to remove ice.

본 발명은 회전날개(3)에 코일(13)과 축전기(15)과 배터리(16)와 열선(17)이 같이 붙어 있어 회전을 같이하는 시스템이며, 각종 베어링과 기어장치가 필요가 없이 전기를 만들어 집적 열선에 전기를 공급하는 시스템이므로, 지속적으로 회전날개에 열을 공급하므로 얼음이 생기지 않도록 하고 고장이 거의 없으므로 극한의 극지방이나 고산지대에서도 사용이 가능한 장점이 있다.The present invention is a system in which a coil (13), a capacitor (15), a battery (16) and a hot wire (17) are attached to a rotary vane (3) Since it is a system that supplies electricity to the integrated hot-wire, it supplies the heat to the rotating blades continuously, so there is no ice, and there is little trouble, so it can be used in extreme polar regions and high mountains.

본 발명은 비용이 적게 들고 유지비가 거의 들지 않는 장점이 있어 산업상 이용가능성이 충분하다.The present invention is advantageous in industrial applicability because it has a low cost and a low maintenance cost.
