Description

풍력발전기Wind power generator
본 발명은 풍력발전기에 관한 것으로서, 더욱 더 상세하게는 회전날개를 통해 회전축 방향으로 유입되는 바람에 의해 회전축과 보조발전기에 설치되어 있는 영구자석들이나 발전기축을 포함한 발전장치를 냉각시켜 장비의 내구성을 향상시킬 수 있도록 발명된 것이다.The present invention relates to a wind power generator, and more particularly, by cooling the power generation device including permanent magnets or generator shafts installed in the rotating shaft and the auxiliary generator by the wind flowing in the direction of the rotating shaft through the rotary blades, thereby improving durability of the equipment. It is invented to be able to.
일반적으로 전기를 얻기 위한 발전의 형태로서는 물의 낙차를 이용한 수력발전, 연료를 태움으로 얻어지는 화력발전, 핵분열을 이용한 원자력발전 및 바람을 이용한 풍력발전 등으로 구분할 수 있는 것으로서, 계절과 지형적인 영향에 따라 적절한 발전장치를 설치하여 전력을 얻고 있다.In general, the type of power generation to obtain electricity can be divided into hydro power generation using water drop, thermal power generation by burning fuel, nuclear power generation using nuclear fission, and wind power generation using wind. Power is being installed by installing a proper power generation device.
상기 수력발전은 대표적으로 하천에 댐을 건설하여 수위를 높여 낙차를 얻는 방법이 많이 사용되고 자연상태를 이용하기 때문에 대기오염과 같은 공해물질을 배출하지 않고 대용량의 전력을 얻을 수 있는 장점을 가지나 자연환경의 훼손 및 댐의 건설에 따라서는 상류 쪽의 수몰되는 지역에 마을이 있는 경우에 마을을 철거하는데 있어 커다란 사회문제가 되는 경우가 발생한다.The hydroelectric power generation has a merit that a large amount of electric power can be obtained without discharging pollutants such as air pollution since the method of obtaining dams by increasing the water level by constructing dams in rivers is typically used. The destruction of the village and the construction of the dams can be a major social problem in the demolition of villages when there are villages in submerged areas.
화력발전은 석탄이나 중유의 연료를 연소시켜 발생한 열로 물을 가열하여 고온, 고압의 증기를 발생시켜 증 기터빈을 통해서 전력을 발생시키나 연료를 연소하였을 때 발생하는 대기오염과 연료로 이용되는 천연자원의 고갈을 가져오는 문제점이 발생된다.Thermal power plants heat water with heat generated by burning fuel of coal or heavy oil to generate high temperature and high pressure steam to generate power through steam turbines, but natural resources used as air pollution and fuel generated when burning fuel. Problems that result in depletion of
원자력발전은 물을 끓여서 증기를 만들고 이 증기로서 터빈을 돌려 발전을 한다는 점에서는 일반 화력발전방식과 다를 바 없지만, 물을 끓이기 위한 에너지원 공급방식을 화력발전에서는 보일러 내에서의 연소반응에 의존하지만 원자력발전에서는 원자로 내에서의 핵분열반응에 의존한다는 점에서는 차이가 있는 것이다.Nuclear power is no different from conventional thermal power in that it boils water to produce steam and uses turbines to generate electricity by rotating the turbine.However, the method of supplying the energy source for boiling water depends on the combustion reaction in the boiler. The difference is that nuclear power relies on fission reactions in nuclear reactors.
이러한 원자력발전방식은 다른 발전방식에 비해 초기 건설비용이 높은 편이나, 연료비가 월등히 싸기 때문에 발전소의 긴 수명기간을 통해 볼 때 발전비용이 가장 적게 들고, 소량의 연료만으로도 장기간에 걸쳐 발전할 수 있으며 화석연료를 태울 때 나오는 이산화탄소, 아황산가스, 질소산화물 등 유해물질이 방출되지 않기 때문에 온실효과나 산성비로 인한 생태계 위협요인들을 제거할 수 있어서 지구환경보존 측면에서도 효과적이다.The nuclear power generation method has a higher initial construction cost than other power generation methods, but since the fuel cost is much cheaper, the power generation cost is the lowest through the long life of the power plant, and a small amount of fuel can generate power over a long period of time. Since no harmful substances such as carbon dioxide, sulfur dioxide, and nitrogen oxides emitted from burning fossil fuels are emitted, it is effective in the preservation of the global environment by eliminating the ecosystem threats caused by the greenhouse effect or acid rain.
그러나, 기술의 특성상 최첨단 기술이 종합되어야 하는 기술집약형 발전방식이므로 과학 및 관련산업의 발달을 크게 촉진할 수 있는 장점이 있으나 발전과정에서 불가피하게 발생되는 방사선 및 방사선 폐기물을 안전하게 관리하게 처리, 처분해야 하기 때문에 필수 안전장치 설치에 따르는 추가비용이 발생하며, 독성이 강하고 수명이 긴 핵폐기물을 장기간 안전하게 관리해야 하는 점등을 단점으로 들 수 있다.However, due to the nature of technology, it is a technology-intensive power generation method that requires cutting-edge technology to be synthesized. However, it has the advantage of greatly promoting the development of science and related industries, but it must be managed and disposed of safely to manage the radiation and radiation waste inevitably generated during the development process. As a result, the additional cost of installing the necessary safety devices is incurred, and the disadvantage is the lighting that requires long-term safe management of highly toxic and long-life nuclear waste.
상기 수력발전, 화력발전 및 원자력발전은 대용량의 전력을 얻는 발전방식임에 비해, 풍력발전은 자연현상인 바람을 이용하여 전력을 얻는 장치로서 설치비용이 저렴하고 가정이나 지역단위로 개별적 발전을 하기 용이하므로, 바닷가 등 많은 바람이 부는 지역에서 풍력발전기를 많이 설치하여 사용하고 있다. Hydroelectric power generation, thermal power generation and nuclear power generation are power generation methods to obtain a large amount of power, whereas wind power generation is a device that obtains power by using wind, which is a natural phenomenon. Since it is easy, many wind turbines are installed and used in many windy areas such as the beach.
상기 풍력발전 기는 발전기를 풍력에 관계없이 일정한 속도로 회전시킬 필요가 있으므로, 풍속에 따라 풍차날개의 기울기를 바꾸는 등의 제어를 하고 바람이 불지 않거나 계절에 따라 바람이 부는 방향이나 풍속이 일정하지 않을 때에도 필요한 전력을 얻을 수 있도록 축전기나 디젤발전기를 같이 설치하기도 한다.Since the wind generator needs to rotate the generator at a constant speed irrespective of the wind speed, the wind generator controls such as changing the inclination of the windmill blade according to the wind speed, and the wind does not blow or the wind direction or wind speed may not be constant depending on the season. Sometimes they use capacitors or diesel generators to get the power they need.
그러나 이러한 종래 풍력발전기에서는 회전축을 회전시키는 힘이 전적으로 바람의 세기에 의존하고 있으므로, 소정의 풍량 이하의 미풍에서는 회전축이 초기에 회전되기가 어렵고 회전 지속시간이 짧으므로 소정량 이상의 전력을 얻기가 어렵다는 문제점이 있었다.However, in such a conventional wind power generator, the power to rotate the rotating shaft is entirely dependent on the strength of the wind, so it is difficult for the rotating shaft to be initially rotated and the rotation duration is short, so that it is difficult to obtain more than a predetermined amount of power in a breeze of a predetermined wind volume or less. There was a problem.
따라서 종래에도 상기 종래와 같은 문제점을 해결하기 위해 바람의 부딪침에 의해 회전하는 날개가 결합된 회전축이 주발전기에 연결되어 전력을 발생시키는 풍력발생기의 회전축 외측에 영구자석의 자력에 의해 회전축과 방대 방향으로 회전이 이루어지면서 전력을 발생시키도록 하는 보조발전기를 설치하여, 소정의 풍량 이하의 미풍에서도 소정량 이상의 전력을 얻을 수 있도록 하고 있다.Therefore, in order to solve the problems as described above, the rotating shaft combined with the blades rotated by the impact of the wind is connected to the main generator to generate the electric power. As a result, an auxiliary generator for generating electric power while rotating is provided, so that electric power of a predetermined amount or more can be obtained even in a breeze below a predetermined air volume.
그러나 이와 같은 종래의 풍력발전기는 회전날개 및 영구자석의 자력에 의해 회전축 및 보조발전기가 회전시 발생되는 열에 의해 보조발전기가 과열되어 고장 등이 발생하게 되는 문제점이 있었다.However, such a conventional wind power generator has a problem in that the auxiliary generator is overheated by heat generated when the rotating shaft and the auxiliary generator are rotated by the magnetic force of the rotor blade and the permanent magnet, causing a failure.
또한, 상기 회전축 및 보조발전기에 설치되어 있는 영구자석의 자성임계점이 상기 회전축과 보조발전기가 회전되면서 발생되는 열에 의해 낮아지게 됨으로써, 소정량 이상의 전력을 얻을 수 없게되는 문제점이 있었다.In addition, since the magnetic critical point of the permanent magnets installed in the rotary shaft and the auxiliary generator is lowered by the heat generated while the rotary shaft and the auxiliary generator rotate, there is a problem in that a predetermined amount or more of power cannot be obtained.
본 발명의 목적은 상기에서와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 회전날개를 통해 회전축 방향으로 유입되는 바람이 보조발전기로 공급되어 냉각이 이루어지도록 함으로써, 회전축과 보조발전기가 회전시에도 마찰열에 의해 보조발전기가 과열되어 파손되지 않도록 하는 풍력발전기를 제공하는 데 있다.An object of the present invention has been devised to solve the conventional problems as described above, by allowing the wind flowing in the direction of the rotation axis through the rotary blades to be supplied to the auxiliary generator to be cooled, even when the rotary shaft and the auxiliary generator rotates The present invention provides a wind power generator that does not overheat and damage an auxiliary generator by frictional heat.
본 발명의 다른 목적은 회전날개를 통해 회전축 방향으로 유입되는 바람에 의해 회전축과 보조발전기에 설치되어 있는 영구자석이 냉각되어 자성임계점이 높아지도록 함으로써, 적은 양의 바람으로도 적정량 이상의 전력을 발전할 수 있도록 하는 풍력발전기를 제공하는데 있다.Another object of the present invention is to cool the permanent magnets installed in the rotating shaft and the auxiliary generator by the wind flowing in the direction of the rotary shaft through the rotary blades to increase the magnetic threshold point, so that a sufficient amount of power can be generated even with a small amount of wind. It is to provide a wind turbine that allows.
본 발명의 목적을 달성하기 위한 본 발명은 회전날개(210)가 외측부에 결합된 상태로 주발전기(100)의 중심축(110)에 회전 가능하게 설치되는 회전축(200)과, 상기 회전축(200)과 회전축(200) 사이에 영구자석(410)의 자력에 의해 반대방향으로 회전가능하게 중심축(110)에 발전기축(310)이 설치되는 보조발전기(300)로 구성된 풍력발전기(10)에 있어서, 상기 회전날개(210)를 통해 유입되는 공기가 중심축방향으로 유입된 후 영구자석(410) 및 보조발전기(300)의 발전기축(310)으로 공급되도록 하는 냉각파이프(500)가 회전축(200)에 설치되는 것에 의해 달성된다.The present invention for achieving the object of the present invention is a rotary shaft 200 is rotatably installed on the central shaft 110 of the main generator 100 in a state in which the rotary blade 210 is coupled to the outer side, and the rotary shaft 200 In the wind generator 10 consisting of the auxiliary generator 300, the generator shaft 310 is installed on the central shaft 110 to be rotated in the opposite direction by the magnetic force of the permanent magnet 410 between the rotating shaft (200) and the rotating shaft (200). In this case, after the air flowing through the rotary blades 210 is introduced in the direction of the central axis, the cooling pipe 500 to be supplied to the permanent magnet 410 and the generator shaft 310 of the auxiliary generator 300 is the rotary shaft ( 200).
