The present invention relates to a coaxial inverted wind power generator, and more particularly, in a general wind power generator in which the stator and the rotor are rotated by attaching the forward and reverse rotor blades so that the stator and the rotor are opposite to each other on the same axis. The present invention relates to a coaxial inverted wind power generator that can be rotated to increase power generation efficiency.

일반적으로 전기에너지는 석유나 석탄을 원료로 하는 화력발전, 수위차를 이용한 수력발전, 우라늄이나 플루토늄을 이용한 원자력발전 등으로 생산하고 있다. In general, electric energy is produced by thermal power generation using oil or coal, hydroelectric power using water level difference, and nuclear power generation using uranium or plutonium.

전기에너지를 생산하기 위한 여러가지 방법중에서 화력발전은 천연자원의 부족으로 인해서 점점 더 어려워지고, 특히 화력발전과정에 발생되는 유해물질의 공기오염 문제가 심각해서 세계적으로 그 사용을 제한하고 있는 실정이어서 최근에는 원자력을 이용한 발전을 많이 사용하고 있다. 그러나, 이러한 원자력발전은 방사능누출사고에 대한 염려와 원자력발전 후 발생되는 방사능을 함유한 폐기물의 처리에 대한 여러가지 문제점이 있었다.Among various methods for producing electric energy, thermal power generation becomes more difficult due to the lack of natural resources, and in particular, the air pollution of harmful substances generated in the thermal power generation process is seriously restricting its use worldwide. There is a lot of nuclear power generation. However, such nuclear power generation has a number of problems regarding radioactive leakage accidents and the treatment of wastes containing radioactivity generated after nuclear power generation.

상기한 문제점을 해결하기 위해서 자연력을 이용하여 전기에너지를 얻어내려는 노력이 많이 진행되었는데, 그 일예로는 조수간만의 차를 이용한 조력발전, 파도의 높이 차를 이용한 파력발전, 바람을 이용한 풍력발전, 태양열을 이용한 태양열발전, 태양광을 이용한 태양전지발전, 연료로부터 직접 에너지를 얻어내는 연료전지발전 등이 있다. In order to solve the above problems, a lot of efforts have been made to obtain electric energy using natural force. Examples of tidal power generation using tidal wave difference, wave power generation using wave height difference, wind power generation using wind, There are solar power generation using solar heat, solar cell power generation using solar light, and fuel cell power generation that directly obtains energy from fuel.

특히 풍력발전에 사용되는 풍력발전기에 대한 연구가 많이 진행되어 작은 바람이 불어도 발전을 일으킬 수 있을 뿐만아니라, 효율을 극대화시키기 위해서 많은 노력이 기울여지고 있다.

미설명부호인 220, 320은 통상적으로 풍력발전기에 사용되는 피치모터(Pitch Motor)로 상기 풍속풍향센서(500)에 의해서 감지된 풍속에 의해서 각각의 날개의 받음각을 조절할 수 있도록 정,역회전날개(200,300)의 피치각을 조절하는 것이다. 또한, 미설명부호인 410은 풍속풍향센서(500)에서 감지된 풍향에 따라서 몸체를 바람이 부는 방향으로 방향을 전환하는 요모터(Yaw Moter)이다.Reference numerals 220 and 320 are pitch motors that are commonly used in wind power generators, and the forward and reverse rotation blades can adjust the angle of attack of each wing by the wind speed sensed by the wind speed sensor 500. It is to adjust the pitch angle of (200,300). In addition, the reference numeral 410 is a yaw motor (Yaw Moter) for changing the direction of the body in the wind blowing direction according to the wind direction detected by the wind speed sensor 500.

이하, 본 발명의 바람직한 실시예로 형성된 동축반전 풍력발전기의 작동을 설명하면 다음과 같다. Hereinafter, the operation of the coaxial inverted wind power generator formed in the preferred embodiment of the present invention will be described.

도 3에서 표시된 것과 같이 바람이 불어올 경우에는 상기 정회전날개(200)가 회전되고, 상기 정회전날개(200)와 연결되어 회전하는 정회전축(204)이 회전하여 회전자(104)를 회전시킨다. 동시에 상기 정회전날개(200)를 통과한 바람은 역회전날개(300)를 회전시키는데, 받음각이 반대로 형성되어 있으므로 정회전날개(200)와 반대방향으로 회전하게 되고, 상기 역회전날개(300)와 연결되어 회전하는 역회전축(304)이 회전하여 고정자(102)를 회전시킨다. When the wind blows as shown in FIG. 3, the forward rotation blade 200 is rotated, and the forward rotation shaft 204 is connected to the forward rotation blade 200 to rotate to rotate the rotor 104. Let's do it. At the same time, the wind passing through the forward rotation blade 200 rotates the reverse rotation blade 300, since the angle of reception is formed in the opposite direction and rotates in the opposite direction to the forward rotation blade 200, the reverse rotation blade 300 The reverse rotation shaft 304 is rotated in connection with and rotates the stator 102.

상기와 같이 종래의 고정자(102)가 고정되어 있고, 회전자(104)가 회전하여 기전력을 형성시켰을 때보다 고정자(102)가 회전자(104)의 회전방향과는 반대방향으로 회전하기 때문에 상대적으로 회전하는 속도가 회전날개가 1개인 풍력발전기보다 이론적으로 같은 풍속에서 발전기의 고정자와 회전자의 상대속도가 2배로 증가하여 회전자(104)에서 발생되는 전류가 커지는 것이다. As described above, since the stator 102 is fixed and the stator 102 rotates in a direction opposite to the rotation direction of the rotor 104, the rotor 104 rotates to form an electromotive force. In this case, the relative speed of the stator and the rotor of the generator is doubled at the same wind speed than the wind turbine having one rotary blade, thereby increasing the current generated in the rotor 104.

이때 바람이 임의 각도로 불어올 경우에는 풍속풍향센서(500)가 풍향을 감지하여 요모터(Yaw Motor, 410)를 구동시키게 된다. 만약 풍속이 달라지면 풍속풍향센서(500)가 풍속을 감지하여 피치모터(220,320)로 날개의 피치각을 조절하여 적당한 회전을 유지시킨다. In this case, when the wind blows at an arbitrary angle, the wind direction sensor 500 detects the wind direction and drives the yaw motor 410. If the wind speed is different, the wind speed wind direction sensor 500 detects the wind speed and adjusts the pitch angle of the blades with the pitch motors 220 and 320 to maintain proper rotation.

상기 정회전날개(200)와 역회전날개(300)는 사이에 발전부에 의해서 일정공간 이격되게 형성되어 날개 서로간의 간섭현상을 최대한 줄일 수 있도록 형성된 것이다. The forward rotary blade 200 and the reverse rotary blade 300 is formed so as to be spaced apart by a power generation unit between the wings formed to reduce the interference phenomenon between each other as much as possible.

상기한 것과 같이, 본 고안에 의한 동축반전 풍력발전기에 의하면 정회전날개와 역회전날개 사이의 간섭현상이 없고, 고정자와 회전자가 상반회전 되어 발전효율이 높을 뿐만아니라 바람의 방향에 따라 방향을 바꿀 수 있어서 발전효율이 매우 높은 효과가 있으며, 구조가 간단하여 생산비가 저렴한 효과가 있다. As described above, according to the coaxial inverted wind power generator according to the present invention, there is no interference phenomenon between the forward and reverse rotor blades, and the stator and the rotor are rotated in the opposite direction, so that the power generation efficiency is high and the direction is changed according to the wind direction. Since the power generation efficiency is very high, and the structure is simple, the production cost is low cost.
