건물 설치용 풍력발전 풍차 {Wind mill for power generation adapted in building}Wind mill for power generation adapted in building}

본 발명은 풍력발전용 풍차에 관한 것으로, 특히 아파트나 공장, 창고 등의 옥상이나 지붕 등에 설치하여 실내에서 배출되는 배기가스와 자연풍에 의하여 회전하는 풍차의 회전축에 의해 발전기를 회전시켜 전기를 얻음으로서 주차장, 계단 등의 공용전기로서 사용되게 한 건물설치용 풍력발전 풍차에 관한 것이다.The present invention relates to a windmill for wind power generation, in particular installed on the roof or roof of an apartment, factory, warehouse, etc. to obtain electricity by rotating the generator by the rotating shaft of the windmill rotated by the exhaust gas and natural wind discharged from the interior The present invention relates to a wind turbine for building installations that is used as a public electric power for parking lots and stairs.

일반적으로 우리나라 전력생산은 화력발전이 대부분이며 나머지는 원자력 발전에 의해 얻어진다.In general, electricity generation in Korea is mostly thermal power generation, and the rest is obtained by nuclear power generation.

그 중 화력발전은 전력을 생산키 위한 연료비가 막대하여 요즘 같은 초고유가 시대에서 전력생산원가가 너무 커지는 문제가 있고, 석유와 석탄 등에서 배출되는 이산화탄소는 지구온난화의 주원인이 되고 있다. 또한 원자력 발전은 방사성 폐기물의 발생과 초기 설비투자비가 막대한 문제점이 있어 유지비용이 거의 들지 않는 풍력 또는 태양열 발전에 많은 연구개발이 진행되고 있다.Among them, thermal power generation has a huge fuel cost to generate electric power, and thus, in the ultra-high oil price era, the power generation cost is too large. Carbon dioxide emitted from oil and coal has become a major cause of global warming. Nuclear power generation has a lot of research and development in the wind or solar power generation, which generates little radioactive waste and the initial capital investment costs, so that the maintenance cost is little.

전기한 바와 같이 고갈되는 에너지, 고유가, 지구온난화로 인하여 에너지원 을 대체할 만한 신,재생 에너지에 대한 관심이 고조되고 있고, 그 신,재생 에너지는 석유와 석탄 등 이산화탄소를 배출하는 기존의 화석연료를 대체하는 다양한 에너지, 새로운 기술로 개발한 신에너지와 계속 공급이 가능한 재생에너지를 포함하는 바이오에너지, 연료전지, 수소에너지, 태양열, 풍력, 지열, 폐기열 어너지, 소수력, 해양에너지 등이 있으며, 이는 설치 장소 및 이동공간에 따른 제약이 없고 무공해, 무한정한 에너지의 이용으로 연료비가 들지 않고 유지, 보수, 관리가 용이한 장점이 있다.As mentioned above, due to depleted energy, high oil prices and global warming, there is a growing interest in renewable energy, which can replace energy sources, and the renewable energy is the existing fossil fuel that emits carbon dioxide such as oil and coal. Bio energy, fuel cell, hydrogen energy, solar heat, wind power, geothermal energy, waste heat energy, hydropower, marine energy, including new energy developed by new technology and renewable energy that can be supplied continuously. This is because there is no restriction according to the installation place and moving space, pollution-free and unlimited use of energy, it does not incur fuel costs and it is easy to maintain, repair and manage.

이러한 신,재생에너지 중에서도 설치가 간단하고 유지비용이 적게 들며 초기 투자가 적은 방식으로 주거 건축물, 초고층 건축물에 적합한 풍력을 이용한 발전이 선호되고 있다.Among these new and renewable energies, power generation using wind power suitable for residential buildings and high-rise buildings is preferred because of its simple installation, low maintenance cost, and low initial investment.

우리나라에서도 비교적 바람이 많은 대관령, 제주도 등에 대용량의 풍력발전장치가 조성되어 있으나 지형 특성상 전력 수요체와 멀리 떨어져 있는 데 비해 그 생산량이 미비하여 큰 도움이 되지 못하는 경우가 많고, 그 설치비용이 과다하고 이를 유지 관리하는데에도 전문인력과 고비용이 소요되므로 우리나라에서는 적합하지 않은 문제가 있다.In Korea, large-scale wind power generators are established in Daegwallyeong and Jeju Island, which are relatively windy. However, they are far from the power demands due to the topography, and their production is inadequate. There is a problem that is not suitable in our country because it requires professional manpower and high cost to maintain it.

본 발명은 전기한 바와 같이 에너지효율, 환경오염, 설치, 유지비용 등을 감안한 풍력발전장치에 있어서, The present invention, in the wind power generation device in consideration of energy efficiency, environmental pollution, installation, maintenance costs, as described above,

특히 지형 특성으로 인한 한정과 유지보수에 전문인력이 필요하는 등의 문제점을 갖는 대용량의 풍력발전장치를 지양하고 빌딩이나 공장, 아파트 등의 전력 수요처에 직접 설치하여 건물 내에서 소용되고 배출되는 폐에너지와 자연풍을 동시에 이용하여 풍차를 회전시켜 그 회전력에 의해 전력을 생산되게 하므로서 과다한 설치비용이 없이도 설치가 가능하고 전문 인력이 필요없이 유지 보수가 가능한 상태에서 건물의 지하 주차장이나 비상계단 등 공동구역의 전력으로 사용되게 하되,In particular, avoid large-capacity wind power generators that have problems such as limitation and maintenance due to the topography, and install them directly at the power demands of buildings, factories, apartments, etc. By using wind and natural wind at the same time, the windmill is rotated to produce electric power by its rotational power, so it can be installed without excessive installation cost and maintenance is possible without the need for specialized personnel. To be used for power,

특히 그 풍차를 가이드 베인을 갖는 외통체와 내부의 다리우스형 회전체를 결합하여 회전 효율을 배가 되게 하여 최소한의 설비투자와 유지비용으로 에너지 효율을 극대화 되게 한 건물설치용 풍력발전 풍차를 제공하는 것이다.In particular, the windmill is combined with an outer cylinder having a guide vane and an internal Darius-type rotating body to double the rotational efficiency, thereby providing a wind turbine for building installation that maximizes energy efficiency with minimal investment and maintenance cost.

상기와 같은 목적을 달성하기 위한 본 발명은, 외곽회전체와, 외곽회전체의 내부에 베어링에 의해 회전가능하게 축설된 내부 및, 외곽회전체와 내부회전체를 지지하는 받침체로 된 풍차를 구성하여 바람을 효율적으로 이용하게 하는 것인데,The present invention for achieving the above object, the outer rotor, and the inside of the outer rotor is rotatably built by the bearing, and a windmill consisting of a support body for supporting the outer rotor and the inner rotor body To use the wind efficiently,

풍력터어빈은 바람방향에 대한 회전축의 방향에 따라 수평축 풍력터어빈과 수직축 풍력터어빈으로 구분할 수 있으며, 풍력터버빈을 구동시키는 공기력에 따라 양력(Lift)을 이용한 풍력터어빈과 항력(Drag)을 이용한 풍력터어빈으로 구분된다. 수평축 풍력터어빈의 대표적인 예로는 프로펠러(Propeller)형 풍력터어빈을 들 수 있고, 수직축 풍력터어빈으로는 다리우스(Darrieus)형 풍력터어빈을 들 수 있으며, 이들은 모두 양력에 의해 구동되는 풍력터어빈이다.Wind turbines can be divided into horizontal shaft wind turbines and vertical shaft wind turbines according to the direction of the rotational axis with respect to the wind direction, and wind turbines using lift and wind turbines using drag according to the aerodynamic force driving the wind turbines. Separated by. Representative examples of horizontal axis wind turbines are propeller type wind turbines, and vertical axis wind turbines include Dariuse type wind turbines, all of which are driven by lift.

다리우스형 풍력터어빈은 프랑스의 G.J.M. Darrieus에 의해 개발되어 1960년대 중반까지는 거의 이용되지 못하다, 최근들어 캐나다의 NAE/NRC(National Aeron-actical Establishment of the National Research Council of Canada) 기관에 의해 실험 및 응용이 이루어지기 시작하였다.Darius wind turbines are manufactured in France by G.J.M. Developed by Darrieus and rarely used until the mid-1960s, it has recently begun to be tested and applied by the National Aeron-actical Establishment of the National Research Council of Canada (NAE).

다리우스형 풍력터어빈은 프로펠러형 풍력터어빈이 회전축에 한쪽 끝만 고정되어 있는 외팔지지보의 형상을 갖고 회전하므로, 플래핑(flapping), 래깅(lagging)이나 토오셔날(torsional) 운동이나 이의 커플링된 운동에 의해 구조적으로 불안정한 반면에, 터어빈의 양쪽 끝이 회전축에 고정되어 있어 구조적이나 동력학적으로 프로펠러형보다는 안정하게 된다. 도한 회전축이 지면에 대해 수직이므로 에너지 전달장치나 발전기 등의 지상 설치가 가능하게 된다. Darius type wind turbines rotate in the form of cantilever beams in which the propeller type wind turbines are fixed at one end to the axis of rotation, so flapping, lagging or torsional movements or their coupling While structurally unstable by motion, both ends of the turbine are fixed to the axis of rotation, making them more structurally or kinetic than propellers. In addition, since the rotation axis is perpendicular to the ground, it is possible to install the ground such as an energy transmission device or a generator.

일반적으로 수평축 프로펠러형은 별도의 철탑(tower)를 설치하여, 그 위에 에너지 전달장치나 발전기를 설치하기 때문에 유지,관리가 곤란하지만 다리우스형 풍력터어빈은 설치 및 유지, 관리가 용이하다는 장점을 갖게 된다. 다리우스형 풍력터어빈은 회전축에 대해 축대칭(axis-symmetric)인 기하학적 형상을 갖기 때문에 대기의 진입방향에 무관하게 회전할 수 있으므로, 수평축 프로펠러형에서 쓰이는 별도의 요잉운전장치(yawing drive mechanism)가 불필요하게 된다. 또 과속시 회전 자가 실속(stall) 상태에 빠지게 되어 스스로 공기역학적으로 안정하게 되는 등의 장점으로 인하여 점차 그 이용범위가 확대되어 가고 있다. 그러나 다리우스형 풍력터어빈은 정지상태에서 회전하기 시작할 때의 시동토오크가 매우 작게 발생하여 스스로 시동하지 못하기 때문에 실제의 시스템을 구성할 때에는 별도의 보조시동장치 및 보조전원이 필요하게 되는 단점을 갖고 있기도 하다. 이상에 대한 다리우스형 풍력터어빈의 특성을 아래 표에 정리하였다.In general, the horizontal propeller type is equipped with a separate tower, and it is difficult to maintain and manage because an energy transmission device or generator is installed thereon, but Darius type wind turbines have the advantage of easy installation, maintenance and management. . Since Darius type wind turbines have an axis-symmetric geometry with respect to the axis of rotation, they can be rotated regardless of the direction of entry into the atmosphere, eliminating the need for a separate yawing drive mechanism for the horizontal propeller type. Done. In addition, due to the advantage that the rotor falls into a stall (stall) state when the speed is over, and the aerodynamically stable itself, the use range is gradually expanded. However, Darius type wind turbines have very low starting torque when they start to rotate in a stationary state, so they cannot start by themselves. Therefore, a separate auxiliary starting device and auxiliary power are required when constructing an actual system. Do. The characteristics of Darius wind turbines are summarized in the table below.

따라서 본 발명에서 내부 회전체를 다리우스 터어빈으로 형성하고 외곽회전체를 바람방향에 따라 회전하면서 바람유도 베인의 바람방향유도에 공기의 양력에 의해 라디우스 터어빈을 초기시동시키므로서 계속 회전하게 되어 계속적으로 안정 적이고 효율적으로 전기에너지를 얻을 수 있게 한 것이다.Therefore, in the present invention, the inner rotor is formed as a Darius turbine and the outer rotor is rotated in accordance with the wind direction, while the wind turbine induces the radial direction of the wind induction by the lift force of the air and continues to rotate continuously. It is to make it possible to obtain electric energy stably and efficiently.

이상과 같이 본 발명에 의한 건물 설치용 풍력발전 풍차는 저렴한 설치비용으로 소규모의 전력을 필요로 하는 곳에 직접 설치하여 건물 내에서 소용되고 배출되는 배기풍과 자연풍을 동시에 이용되게 하여 바람의 이용 효율을 극대화 시키므로서 별도의 전문 운영자나 운영비 없이 전력을 직접 생산하므로서 초고유가 시대에 있어서 발전에 사용되는 에너지를 절약하는 동시에 이산화탄소 등의 공해가 발생되지 않는 친환경적인 발전장치를 제공하는 효과가 있다.As described above, the wind turbine for building installation according to the present invention is installed directly where a small amount of electric power is required at a low installation cost, thereby maximizing the efficiency of use of wind by allowing the exhaust wind and the natural wind to be used and discharged in the building simultaneously. By directly producing the power without a separate professional operator or operating cost by saving the energy used for power generation in the ultra high oil prices, there is an effect to provide an eco-friendly power generation device that does not generate pollution, such as carbon dioxide.
