Description

흡기실과 배기실을 구비한 수직축 풍력발전기Vertical axis wind turbine with intake chamber and exhaust chamber
본 발명은 흡기실과 배기실을 구비한 수직축 풍력발전기에 관한 것으로서, 더욱 상세하게는 흡기실로 흡입된 바람이 배기실로 빠져 나가면서 터빈을 돌려 발전하는 수직축 풍력발전기에 관한 것이다.The present invention relates to a vertical axis wind turbine having an intake chamber and an exhaust chamber, and more particularly, to a vertical axis wind turbine that rotates a turbine to generate electricity while the wind sucked into the intake chamber escapes to the exhaust chamber.
화석에너지로부터 발생되는 온실가스를 줄이기 위해 전 세계가 국제기후변화협약을 채택하고, 다양한 방법으로 이산화탄소 배출 억제를 위해 노력하고 있다. 이에 따라 석유, 석탄 등의 화석연료 대신 태양열, 태양광, 풍력, 지열, 소수력을 이용하는 재생에너지 발전의 필요성이 증가하고 있다. 신재생에너지 중의 하나인 풍력발전은 자연 바람의 힘을 이용하여 회전자를 회전시켜 기계적 에너지로 변환시키고 이 기계적 에너지로 전기를 발생시키는 것이다.In order to reduce greenhouse gases generated from fossil energy, the world has adopted the International Climate Change Convention and is making efforts to curb carbon dioxide emissions in various ways. Accordingly, the need for renewable energy generation using solar heat, sunlight, wind power, geothermal heat, and small hydropower instead of fossil fuels such as petroleum and coal is increasing. Wind power generation, one of the new and renewable energy sources, uses the force of natural wind to rotate a rotor and converts it into mechanical energy, which generates electricity with the mechanical energy.
풍력발전은 무공해 발전 방식이며 대규모 발전단지를 건설함으로써 발전 단가를 낮출 수 있는 장점이 있으나, 바람의 속도가 낮을 경우에는 발전이 불가능하므로 특정 지역에 한정되어 개발되고 있으며, 최근 풍력발전기의 대형화로 인해 소음문제, 회전하는 블레이드의 그림자 문제 등이 해결해야 할 문제점들이다.Wind power generation is a pollution-free power generation method and has the advantage of lowering the unit cost of power generation by constructing a large-scale power generation complex. Noise problems and shadow problems of rotating blades are problems to be solved.
풍력발전기는 회전축의 방향에 따라 수평축 발전기와 수직축 발전기로 나뉘는데, 회전축이 지면에 대해 수평으로 설치되어 있는 수평축 발전기는 수직축 발전기에 비해 효율이 높은 반면, 발전기가 지지탑 상층부에 설치되어 있고 바람의 방향에 따라 발전기의 방향이 회전해야 하고, 바람의 세기에 따라 블레이드 각도를 조절해야 하는 복잡한 구조로 인해 사고가 많이 발생하며 이로 인해 운전시간이 줄어드는 단점이 있다. Wind turbines are divided into horizontal axis generators and vertical axis generators according to the direction of the rotation axis. Horizontal axis generators with rotation axis installed horizontally to the ground are more efficient than vertical axis generators, while the generator is installed on the upper part of the support tower and the wind direction Due to the complex structure in which the direction of the generator must be rotated according to the direction and the blade angle must be adjusted according to the strength of the wind, many accidents occur, which reduces the operating time.
회전축이 지면에 대해 수직으로 설치되어 있는 수직축 발전기는 수평축 발전기에 비해 발전 효율이 떨어진다는 단점이 있지만, 바람의 방향과 관계없이 발전기의 방향을 조절할 필요 없을 뿐 아니라 발전기가 지상에 있어 유지보수가 간편하다는 점에서 소규모 풍력발전에 많이 사용되고 있다.Vertical shaft generators, in which the rotating shaft is installed vertically to the ground, have the disadvantage of lower power generation efficiency than horizontal shaft generators. It is widely used in small-scale wind power generation.
수평축 발전방식에서는 모든 블레이드가 한쪽 방향의 회전에 도움을 주지만 기존의 수직축 발전방식에서는 한쪽 블레이드의 회전방향이 다른 쪽 회전방향의 힘보다 더 커서 돌아가는 방식이므로 근본적으로 발전효율의 한계가 있다. 수평축 발전방식에서는 블레이드의 수가 많을수록 발전량에는 도움이 되지만 블레이드 가격이 비싸다는 점과 그 무게로 인해 지지탑의 건설비용이 비싸진다는 점 그리고 강풍이 불 때 위험하다는 점 때문에 3개의 블레이드 방식이 많이 사용되고 있다.In the horizontal axis power generation method, all blades help to rotate in one direction, but in the existing vertical axis power generation method, the rotational direction of one blade is greater than the force in the other rotational direction, so there is a fundamental limitation in power generation efficiency. In the horizontal axis power generation method, the more blades there are, the more helpful the amount of power generation, but the cost of blades is high, the cost of constructing a support tower is high due to its weight, and it is dangerous when strong winds blow, so the three-blade method is widely used. .
만약 수직축 발전을 하면서 수평축 방식의 블레이드를 사용할 수 있다면 효율을 높이면서도 유지보수가 간편해지며 수십 미터의 큰 블레이드를 사용하지 않아도 되므로 안정성도 높일 수 있다.If horizontal-axis blades can be used while generating vertical-axis power generation, efficiency can be increased, maintenance can be simplified, and stability can be improved because large blades of tens of meters do not need to be used.
수직축 발전기의 효율을 높이기 위해 바람의 속도를 증가시키고 회전에 유리하도록 바람의 방향을 바꾸고자 하는 연구가 제안되어 있으며 한국공개특허 제10-2011-0040328호에 개시되어 있다. 어느 방향에서 바람이 불든 블레이드가 잘 돌아갈 수 있는 방향으로 바람을 유도하고 있으나 바람이 빠져나가는 영역에서는 블레이드의 회전을 방해하는 구조이므로 개선효과는 크지 않다. In order to increase the efficiency of a vertical axis generator, a study to increase the speed of the wind and change the direction of the wind to favor rotation has been proposed, and is disclosed in Korean Patent Publication No. 10-2011-0040328. No matter which direction the wind blows, the wind is induced in a direction where the blade can rotate well, but the improvement effect is not large because the structure hinders the rotation of the blade in the area where the wind escapes.
미국등록특허 제10,378,509호에 임의의 방향에서 불어오는 수평방향의 바람을 수직 방향으로 변환함으로써 고효율의 터빈을 사용 가능하도록 하는 방식도 제안되어 있다. 이 방식은 유입된 바람이 원하는 방향으로 가기도 하고 바람이 불지 않는 방향으로 빠져나가기도 하여 효율을 떨어뜨린다. 바람이 불어오는 방향으로 들어온 공기가 반대쪽으로 빠져나가지 않고 블레이드 쪽으로만 갈 수 있도록 반대쪽을 막아 줄 필요가 있다.U.S. Patent No. 10,378,509 also proposes a method of enabling a highly efficient turbine to be used by converting horizontal wind blowing from an arbitrary direction into a vertical direction. In this method, the inflowed wind goes in the desired direction or escapes in the direction where the wind does not blow, reducing efficiency. It is necessary to block the other side so that the air entering the windward direction can only go to the blade side without escaping to the other side.

The shield of the block is configured to open only outward, so the windward shield is closed by the force of the wind, and the other side is configured to be opened by the force of the wind coming from the air intake room, so it is driven by the force of the wind without a separate driving device characterized by being

도 1은 본 발명에 따른 흡기실과 배기실을 구비한 수직축 풍력발전기의 수직 단면도로서, 바람이 불어오는 쪽의 벽은 개방되고 반대 방향의 벽은 막혀있는 흡기실(11); 상기 흡기실과는 높이를 달리하여 연결되지만 바람이 불어오는 쪽의 벽은 막혀있고 반대 방향의 벽이 개방되어 흡기실로 들어온 바람이 빠져나가는 배기실(12); 상기 흡기실과 배기실의 연결통로에 바람이 통과하면서 회전하는 터빈(13); 상기 터빈의 회전력에 의하여 발전하는 수직축 발전기(14) 및 상기 흡기실과 배기실의 벽은 한쪽 방향으로만 선택적으로 개폐되는 복수의 차단막(15f, 15r, 16f, 16r)을 포함한다.Figure 1 is a vertical cross-sectional view of a vertical axis wind turbine having an intake chamber and an exhaust chamber according to the present invention, the windward wall is open and the opposite wall is closed intake chamber (11); An exhaust chamber 12 connected to the intake chamber at a different height, but a wall on the windward side is blocked and a wall on the opposite side is open so that the wind entering the intake chamber escapes; A turbine 13 rotating while wind passes through the connecting passage between the intake chamber and the exhaust chamber; The vertical shaft generator 14 generating power by the rotational force of the turbine and the walls of the intake and exhaust chambers include a plurality of blocking films 15f, 15r, 16f, and 16r that are selectively opened and closed in one direction only.
상기 흡기실(11)은 바람이 인입되는 방으로 바람을 맞이하는 벽의 차단막(15f)은 개방되고 반대 방향의 벽의 차단막은 차폐되어 인입되는 바람의 압력을 높일 수 있다.The intake chamber 11 is a room into which wind enters, and the blocking film 15f of the wall facing the wind is opened and the blocking film of the opposite wall is shielded to increase the pressure of the incoming wind.
상기 배기실(12)은 바람이 빠져나가는 방으로 상기 흡기실과 연결되되 높이를 달리한다. 도 1에서는 흡기실을 상부로 하고 배기실을 하부로 하였으나 그 반대로 배기실을 상부로 흡기실을 하부로 배치할 수 있다. 배기실은 흡기실과는 반대로 바람이 불어오는 쪽의 차단막(16f)은 닫히고 반대쪽의 차단막(16r)은 개방되어 바람이 빠져나가게 된다.The exhaust chamber 12 is a room through which wind escapes and is connected to the intake chamber but has different heights.

본 발명의 흡기실과 배기실은 바람 방향의 수평축을 기준으로 상하로 높이 차이가 있는 것이 특징이다. 동일 높이에 있으면 바람이 블레이드를 미는 추진력으로 수직축을 회전시키지만, 블레이드가 180°회전되면 불어오는 바람에 블레이드를 회전하지 못하도록 저항력이 발생하여 발전효율이 떨어진다. 저항력을 줄이기 위하여 블레이드의 형상을 저항이 작도록 곡선형태로 변경하거나 저항력을 발생시키는 맞바람을 차폐해야 한다. The intake chamber and the exhaust chamber of the present invention are characterized in that there is a difference in height with respect to the horizontal axis in the wind direction. When the blades are at the same height, the wind pushes the blades to rotate the vertical axis, but when the blades are rotated 180°, resistance is generated to prevent the blades from rotating in the blowing wind, reducing power generation efficiency. In order to reduce the resistance, the shape of the blade must be changed to a curved shape to reduce the resistance or the wind that generates the resistance must be shielded.
본 발명은 맞바람을 피하기 위하여 유로를 수평에서 수직으로 변경하고 차단막을 두어 차단한다. 흡기실과 배기실을 높이차로 분리하고 배기실의 유입구를 차단하여 불어오는 바람에 의한 저항력을 없앨 수 있다. 또한 공기의 유로를 수직으로 변경하여 임펠라 날개깃을 가진 터빈을 사용하여 회전시킬 수 있다.In the present invention, in order to avoid head wind, the flow path is changed from horizontal to vertical and a blocking film is placed to block it. The intake chamber and the exhaust chamber are separated by a height difference, and the inlet of the exhaust chamber is blocked to eliminate the resistance caused by the blowing wind. It can also be rotated using a turbine with impeller blades by changing the air flow vertically.
도 2는 도 1의 A-A' 선을 따라 절단한 평면도로서, 상기 흡기실과 배기실은 분리벽(17)이 형성되고 중앙에 공기가 유통될 수 있는 구멍이 형성되어 터빈(13)이 설치된다. FIG. 2 is a plan view taken along the line A-A' of FIG. 1, in which a separating wall 17 is formed in the intake chamber and the exhaust chamber, and a hole through which air is circulated is formed in the center to install a turbine 13.
흡기실로 들어온 바람은 배기실로 빠져나가면서 터빈을 회전시켜 수직축 발전기(14)에서 전력을 생산한다.The wind entering the intake chamber rotates the turbine while passing through the exhaust chamber to produce power in the vertical shaft generator 14 .
상기 흡기실, 배기실 및 터빈을 하나의 풍력모듈로 하여 수직축에 복수로 설치하여 회전력을 증가시킬 수 있다. 풍력모듈의 외벽 형태는 도 2와 같이 다각형으로 형성하여 불어오는 바람을 최대한 이용할 수 있다.Rotational force may be increased by installing a plurality of the intake chamber, the exhaust chamber, and the turbine as one wind power module on a vertical shaft. The shape of the outer wall of the wind power module is formed in a polygonal shape as shown in FIG. 2 to maximize use of the wind blowing.
도 3 내지 도 5는 본 발명에 따른 차단막의 실시예로서, 복수의 차단막은 회전수단(미도시)과 회전수단을 제어하는 제어기(미도시)에 의하여 풍향에 따라 자동 개폐할 수 있다. 제어기에 의하여 유입되는 공기의 양을 조절할 수 있어 발전기를 최적의 발전 상태로 유지할 수 있다.3 to 5 are examples of the blocking film according to the present invention, and a plurality of blocking films can be automatically opened and closed according to the wind direction by a rotating means (not shown) and a controller (not shown) that controls the rotating means. Since the amount of air introduced by the controller can be adjusted, the generator can be maintained in an optimal state of power generation.
또한, 복수의 차단막은 바람이 한쪽 방향으로만 흐르도록 체크밸브식으로 구성하여 바람의 힘만으로 차단막을 개폐할 수도 있다.In addition, the plurality of blocking films may be configured in a check valve type so that wind flows in only one direction, so that the blocking films may be opened and closed only by the force of wind.
흡기실의 입구쪽 차단막(15f)은 안쪽으로만 열리도록 구성되어 바람이 불어오는 쪽의 차단막은 바람의 힘에 의해 열리고, 바람이 나가려고 하는 쪽의 차단막(15r)은 바람의 힘에 의해 닫히며, 배기실의 차단막은 바깥쪽으로만 열리게 구성되어있어 바람이 불어오는 쪽 차단막(16f)은 바람의 힘에 의해 닫히고 반대쪽 차단막(16r)은 공기유입용 방에서 들어온 바람의 힘에 의해 열리도록 구성되어 별도의 구동장치 없이 바람의 힘으로 개폐된다.The blocking film 15f on the inlet side of the intake chamber is configured to open only inward, so that the wind blowing side blocking film is opened by the force of the wind, and the wind blowing side blocking film 15r is closed by the force of the wind. In addition, the blocking film of the exhaust chamber is configured to open only outward, so that the windward blocking film (16f) is closed by the force of the wind and the opposite blocking film (16r) is configured to be opened by the force of the wind coming from the air inlet room. It opens and closes with the force of the wind without a separate driving device.
본 발명의 다른 실시예로서 바람의 방향에 따라 차단막을 개폐하는 대신에, 차단막의 열림과 닫힘상태를 고정한 상태에서 흡기실과 배기실 한 몸이 되어 바람의 방향에 따라 회전할 수도 있다.As another embodiment of the present invention, instead of opening and closing the shield according to the direction of the wind, the intake and exhaust chambers may rotate according to the direction of the wind while the open and closed states of the shield are fixed.
차단막의 형태를 변경함으로써 유입되는 공기의 양을 최대화할 수 있으며 이에 따라 바람의 속도를 높일 수 있다. By changing the shape of the barrier, the amount of inflow air can be maximized and, accordingly, the wind speed can be increased.
도 3은 차단막이 일자형의 수직형태이고, 도 4는 유입구가 경사진 시그마(Σ) 형태로 유속을 높일 수 있다. 도 5는 배기실의 입구쪽 차단막이 원호 형태로 공기마찰을 줄이고 풍량을 증가시킬 수 있다.In FIG. 3, the blocking film has a straight vertical shape, and in FIG. 4, the flow rate can be increased in the form of a sigma (Σ) inlet with an inclined inlet. 5 shows that the inlet-side blocking film of the exhaust chamber has an arc shape, reducing air friction and increasing air volume.
본 발명은 기존의 수직축 풍력 발전의 문제점인 반대방향으로 빠져나가는 바람을 막아 활용함으로써 발전효율을 향상시킬 수 있어 수직축 풍력 발전기에 적용할 수 있다.The present invention can be applied to a vertical axis wind power generator because it can improve the power generation efficiency by blocking and utilizing the wind that escapes in the opposite direction, which is a problem of the existing vertical axis wind power generation.
