지주에 풍향타가 설치된 수직축 풍력 발전기{Vertical axis wind power generator}Vertical axis wind power generator with wind vane installed on the shore

본 발명은 지주에 풍향타가 설치된 수직축 풍력 발전기에 관한 것이다. 발전축을 회전시키는 회전체를 변화하는 풍향을 따라 큰 풍압면을 가지도록 자동으로 방향을 잡도록하는 풍향타가 지주에 설치된 구조이다. 따라서 종래에는 풍향타가 회전체에 설치되어 부하 저항으로 작용하였으나, 본 발명은 이러한 발전효율의 저하 문제점을 회전체의 회전 저항을 줄임으로써 해소하여 발전 효율을 증대시키고, 내구 수명 또한 증대케 한 발명이다.The present invention relates to a vertical axis wind power generator is installed on the prop. The wind vane is automatically installed on the prop so as to automatically orientate the rotor to rotate the power generating shaft to have a large wind pressure surface. Therefore, in the past, the wind deflector was installed on the rotating body to act as a load resistance, but the present invention solves the problem of lowering the power generation efficiency by reducing the rotating resistance of the rotating body, thereby increasing power generation efficiency and increasing durability life. .

수직축 풍력발전기는 지상에 설치된 지주와, 상기 지주의 내부에 수직으로 설치된 발전축과, 상기 발전축 상단에 설치된 회전체와 회전체에 설치된 풍향타를 포함하여 구성된다. 물론 발전축은 증속기와 발전기에 연결되어 발전하고, 이를 축전하는 축전기가 부가될 수 있다.The vertical axis wind turbine includes a prop installed on the ground, a power generating shaft installed vertically inside the support, and a wind vane installed on the rotating body and the rotating body installed on the top of the power generating shaft. Of course, the power generation shaft is connected to the speed increaser and the generator to generate power, and a capacitor for storing the power may be added.

상기의 풍향타는 회전체에 설치된 회전날개가 발전축을 회전시켜 발전을 행 하는 정회전 방향으로는 큰 풍압을 받고, 역회전 방향으로는 작은 풍압을 받도록 그 각도를 자동으로 잡아 주는 역할을 하고, 풍압을 받지 않는 회전날개는 풍압면을 작게 하는 역할을 한다.The wind vane serves to automatically grasp the angle so that the rotary blade installed on the rotating body receives a large wind pressure in the forward rotation direction to generate power by rotating the power generation shaft, and a small wind pressure in the reverse rotation direction, Rotating blades that do not receive serves to reduce the wind pressure surface.

따라서 풍향타에 의해 전체적인 회전체의 회전각도와, 회전체에 설치된 회전날개의 상대 각도를 자동으로 설정될 수 있도록 하여 최적의 발전효율을 달성하고 있다.Therefore, the wind angle and the rotation angle of the entire rotating body and the relative angle of the rotary blades installed on the rotating body can be automatically set to achieve the optimum power generation efficiency.

풍향에 따라 날개면의 각도가 자동 조절되어지는 종래의 수직축 풍력 발전기에는 풍향타가 필수적으로 사용되어야 하나 종래의 경우 풍향타가 회전체에 설치됨으로써 회전체가 풍향타의 하중까지 지지하여야 하는 부담을 가지게 되고, 실질적인 발전을 위해 발전축을 회전시키는 회전체의 회전 운동이 풍향타의 하중에 의해 저항을 받게 된다.The wind rudder must be used in a conventional vertical axis wind power generator whose angle of the wing surface is automatically adjusted according to the wind direction, but in the conventional case, the wind rudder is installed on the rotating body, so that the rotating body has to bear the load of the wind rudder. The rotational movement of the rotating body rotating the power generating shaft for the actual power generation is resisted by the load of the wind vane.

따라서 종래의 구조에서는 발전 효율이 저하되고, 큰 하중이 회전체에 부가되어 운동부분의 소손 등이 발생되는 등 내구 수명이 짧은 문제가 있었다.Therefore, in the conventional structure, there is a problem in that the power generation efficiency is lowered, and a large load is added to the rotating body, causing burnout of the moving part, and the like.

본 발명은 상기와 같은 내구 수명 단축 및 발전 효율 저하의 문제점을 해소하고자 함에 목적이 있다.An object of the present invention is to solve the problems of shortening the endurance life and deterioration of power generation efficiency.

본 발명은 회전체에 다른 하중 부하를 주지 않도록 하여 발전을 위한 회전이 용이하게 이루어지도록 하기 위하여, 풍향타를 지주에 설치된 구조를 제공하게 된다. 그리고 풍향타와 회전체의 회전날개는 체인 등으로 연결되어 정확하게 풍향에 따라 최적의 풍압면적을 가지도록 된 구조를 제공하게 된다.The present invention provides a structure in which the wind deflector is installed on the support so that the rotation for power generation can be easily performed by not giving another load load to the rotating body. And the wind vane and the rotor blades of the rotating body is connected by a chain or the like to provide a structure that has an optimal wind pressure area according to the wind direction exactly.

본 발명은 풍향타가 회전체에 하중 부하를 주지 않는 구조를 제공함으로써, 회전체의 회전 운동이 원활하여 발전 효율이 증대되고, 소음과 진동 등이 경감되어 내구 수명이 증대되는 효과가 있다.According to the present invention, by providing a structure in which the wind deflector does not apply a load load to the rotating body, the rotational movement of the rotating body is smooth, the power generation efficiency is increased, and noise and vibration are alleviated, so that the durability life is increased.

본 발명은 수직으로 설치된 관체의 지주(1); 상기 지주(1)의 내부에 설치된 발전축(2); 상기 발전축(2)의 상단에 발전축(2)을 중심으로 대칭되게 고정설치되고, 끝단에 다수 개의 회전날개(3)가 설치된 회전체(4); 상기 발전축(2)에 연결된 발전기(5);를 포함하여 구성된 수직축 풍력 발전기에 관한 것이다.The present invention is a support (1) of the tubular body installed vertically; A power generation shaft 2 installed inside the prop 1; A rotating body (4) fixedly symmetrically installed around the power generating shaft (2) at the top of the power generating shaft (2), and having a plurality of rotary blades (3) installed at ends; It relates to a vertical axis wind power generator, including; a generator (5) connected to the power generation shaft (2).

특히 회전체(4)에 설치된 회전날개(3)의 회전 각도 즉 자전 각도를 풍향에 따라 최적으로 변화될 수 있도록 하는 풍향타(6)가 지주(1)에 설치된 구조에 특징이 있다.In particular, the wind vane 6 is installed in the support 1 so that the rotation angle, that is, rotation angle, of the rotary blade 3 installed on the rotor 4 can be optimally changed according to the wind direction.

풍향타(6)는 풍향을 추종하는 구조로 되어야 하므로, 회전되는 구조가 필요하고, 이는 허브(7)가 담당하게 된다. 따라서 풍향타(6)는 허브(7)에 설치되고, 허브(7)는 지주(1)에서 회전되는 구조이다.Since the wind vane 6 should be a structure that follows the wind direction, it is necessary to rotate the structure, which is the hub (7) will be in charge. Therefore, the wind vane 6 is installed in the hub 7, and the hub 7 is rotated in the support (1).

즉, 풍향타(6)가 부착된 관체의 허브(7)가 상기 지주(1)의 상단 외측에 삽입되게 설치되되, 지주(1)의 외측면과 허브(7)의 내측면은 베어링(8)으로 고정되어 허브(7)가 회전되는 구조이고; 허브(7)의 상부에 다수 개의 체인스프로켓이 설치되며; 상기 회전날개(3)의 날개축(9)에 체인스프로켓이 설치되고; 허브(7)의 체인스프로켓과 날개축(9)의 체인스프로켓이 체인(10)으로 연결된다.That is, the hub 7 of the tubular body to which the wind vane 6 is attached is installed to be inserted outside the upper end of the support 1, and the outer surface of the support 1 and the inner surface of the hub 7 are bearings 8. Is fixed to) and the hub 7 is rotated; A plurality of chain sprockets is installed on the top of the hub 7; A chain sprocket is installed on the wing shaft 9 of the rotary blade 3; The chain sprocket of the hub 7 and the chain sprocket of the wing shaft 9 are connected to the chain 10.

물론 회전날개(3)와 풍향타(6)와의 동기화 또는 타이밍은 체인스프로켓과 체인(10)의 결합으로 가능할 수 있고, 체인스프로켓 대신에 풀리로 구성하거나, 체인(10) 대신에 타이밍 밸트로 구성할 수도 있다.
따라서 본 발명에서는 회전날개(3)와 풍향타(6)와의 동기화 또는 타이밍을 위해 체인스프로켓과 체인(10)을 결합한 구조를 실시예로 설명하지만, 풀리와 타이밍 밸트를 포함하는 의미로 사용하기로 한다.Of course, the synchronization or timing of the rotary blade (3) and the wind vane (6) may be possible by the combination of the chain sprocket and the chain 10, consisting of a pulley instead of the chain sprocket, or composed of a timing belt instead of the chain (10) You may.
Therefore, the present invention describes a structure in which the chain sprocket and the chain 10 are combined for synchronizing or timing the rotor blade 3 and the wind vane 6 by way of example, but are used to include a pulley and a timing belt. do.

체인스프로켓은 회전체(4)에 설치된 회전날개(3)의 갯 수만큼 설치되고, 각각 일대일로 대응되도록 각각의 체인(10)으로 체결된다. 도면에 도시된 실시예는 회전날개(3)가 두 개 설치된 구조로서, 그 각각의 날개축(9)에 체인스프로켓(11aa)(11bb)이 설치되고, 허브(7)에는 체인(10)으로 연결되는 체인스프로켓(12a)(12b)이 설치되어, 체인스프로켓(11aa)과 체인스프로켓(12a), 체인스프로켓(11bb)과 체인스프로켓(12b)이 체인으로 체결되어 한 쌍을 이루어 동기화된다.Chain sprockets are installed as many as the number of the rotary blades (3) installed on the rotating body (4), and are fastened to each chain (10) so as to correspond to each one in one. The embodiment shown in the figure is a structure in which two rotary blades 3 are installed, the chain sprocket (11aa) (11bb) is installed on each wing shaft (9), the hub (7) as a chain (10) Chain sprockets 12a and 12b connected to each other are installed, and the chain sprockets 11aa and the chain sprockets 12a, the chain sprockets 11bb and the chain sprockets 12b are fastened by chains, and are synchronized as a pair.

상기와 같은 본 발명의 특징적인 구조에 의하여, 풍향타(6)가 부착된 허브(7)는 풍향타(6)와, 체인스프로켓(12a)(12b)을 지지하지만, 지주(1)에 그 지지 기반을 두고 있기 때문에 회전체(4)에는 어떠한 무게나 회전에 대한 저항으로 작용하지 않게 된다.According to the characteristic structure of the present invention as described above, the hub 7 to which the wind vane 6 is attached supports the wind vane 6 and the chain sprockets 12a and 12b, Because of the support base, the rotor 4 does not act as a resistance to any weight or rotation.

이와 같은 본 발명은 우선 수직축 풍력발전기에 설치되는 풍향타(6)에 의하여 회전체(4)의 회전날개(3)의 방향을 풍향에 대해 최적의 각도를 유지하게 된다. 즉, 도 3에 도시된 바와 같이, 발전축(2)을 발전을 위한 회전방향인 정방향(도 3에서 시계 방향)으로 회전하는 것으로 가정할 경우, 상부 반원부에 위치되는 회전날개(3)는 발전축(2)의 정방향 회전에 저항이 작게 발생하도록 풍압면적이 최대한 적어야 한다. 그리고 하부 반원부에 위치되는 회전날개(3)는 발전축(2)을 회전시키는 힘을 받을 수 있도록 큰 풍압면적을 가지는 각도를 유지해야 한다.In the present invention as described above, the direction of the rotary vanes 3 of the rotor 4 by the wind vane 6 installed in the vertical shaft wind turbine is maintained at an optimum angle with respect to the wind direction. That is, as shown in Figure 3, assuming that the power generating shaft (2) rotates in the forward direction (clockwise in Figure 3) that is the rotation direction for power generation, the rotary blades 3 located in the upper semicircle The wind pressure area should be as small as possible so that the resistance is small in the forward rotation of the power generating shaft (2). And the rotary vanes 3 located in the lower semicircle should maintain an angle having a large wind pressure area to receive the force to rotate the power generating shaft (2).

따라서 도 3에 도시된 바와 같은 회전날개(3)의 각도를 가지도록 초기 설정을 행하고, 체인(10)으로 체인스프로켓(11aa)(11bb)과 체인스프로켓(12a)(12b)을 연결하면, 풍향이 바뀌더라도 풍향타(6)에 의해 항상 초기 설정된 회전날개(3)의 자전각도를 가질 수 있게 된다.Therefore, if the initial setting is made to have the angle of the rotary blade 3 as shown in Figure 3, and the chain sprockets 11aa, 11bb and the chain sprockets 12a, 12b by the chain 10, the wind direction Even if this is changed, it is possible to always have the rotation angle of the rotary blade 3 initially set by the wind vane 6.

상기와 같이 풍향타(6)는 풍향에 따라 회전되는데, 이는 지주(1)에 베어링(8)으로 설치된 허브(7)에 의해 아주 용이하게 움직이게 된다. 즉, 도 2에 도시된 바와 같이 허브(7)는 지주(1)의 상단에 삽입되어 설치되고, 베어링(8)에 의해 지주(1)를 중심으로 회전이 자유롭게 설치된다.As described above, the wind vane 6 is rotated according to the wind direction, which is easily moved by the hub 7 installed as a bearing 8 on the support 1. That is, as shown in FIG. 2, the hub 7 is inserted and installed at the upper end of the support 1, and rotation is freely installed about the support 1 by the bearing 8.

따라서 풍향이 바뀔 경우 풍향타(6)가 풍압을 받아 풍향의 방향으로 다시 방향을 잡게 되고, 이는 허브(7)가 지주(1)에서 매우 자유롭게 회전되기 때문이다. 그리고 도 3에 도시된 회전날개(3)의 자세를 가지게 된다.Therefore, when the wind direction is changed, the wind vane 6 receives the wind pressure and reorients in the direction of the wind direction, because the hub 7 is rotated very freely in the support 1. And it has a posture of the rotary blade (3) shown in FIG.

풍향이 변화하지 않을 경우에는 도 3과 같은 상태에서 하측에 도시된 회전날개(3)가 최대의 풍압을 받고, 상부에 도시된 회전날개(3)는 풍압을 작게 받게 되어, 점차 시계 방향으로 회전체(4)가 회전된다. 회전체(4)의 회전에 따라 회전날개(3)의 자전 각도가 변화되어 가면서 상부측에서 회전 저항을 발생시키지만 최소화되고, 하부측으로 회전되어 갈수록 큰 풍압이 발생되어 회전력이 증대된다.If the wind direction does not change, the rotary blade 3 shown at the lower side receives the maximum wind pressure in the state shown in FIG. 3, and the rotary blade 3 shown at the top receives the wind pressure small, gradually turning clockwise. The whole 4 is rotated. As the rotation angle of the rotary blade 3 changes as the rotation of the rotor 4 changes, the rotation resistance is generated at the upper side but is minimized, and a large wind pressure is generated as the rotating side is rotated to increase the rotational force.

최적의 풍압을 받을 수 있도록 회전체(4)를 풍향을 따라 회전시키는 풍향타(6)는 회전체(4)의 회전에 어떠한 저항으로도 작용하지 않는다. 이는 풍향타(6)가 회전체(4)에 설치되지 않고, 허브(7)를 매개로 하여 지주(1)에 설치됨으로써 가능하다.The wind vane 6 which rotates the rotor 4 along the wind direction to receive the optimum wind pressure does not act as any resistance to the rotation of the rotor 4. This is possible because the wind vane 6 is not installed on the rotating body 4 but is installed on the support 1 via the hub 7.

따라서 회전체(4)의 하중이 경감되는 효과가 되어, 바람에 의한 회전이 매우 용이하게 일어나고, 회전력은 발전축(2)의 회전력으로 모두 변환되어 발전효율의 증대와 내구 수명이 증대된다.Therefore, the load of the rotating body 4 is reduced, and rotation by wind occurs very easily, and the rotational force is all converted into the rotational force of the power generating shaft 2, so that the power generation efficiency is increased and the endurance life is increased.
