Abstract

The present invention relates to a wind power generator for producing electric energy by using wind and, more specifically, provides a wind power generator for allowing only blades positioned higher than a horizontal rotary shaft to collide with the wind by a fixed windbreak and rotate at normal times, thereby preventing the blades positioned at the upper and lower sides of the horizontal rotary shaft from simultaneously colliding with the wind and stopping without rotating due to the equilibrium of force and, specifically, raising, the liftable windbreak, which is provided in the fixed windbreak, above the fixed windbreak when a storm or a strong wind blows, so as to block the front of the blade positioned higher than the horizontal rotary shaft, thereby preventing the blades or other components from being broken by the strong wind.

The installation cost and installation area are very economical and do not cause environmental pollution compared to nuclear power, hydropower and thermal power.
이러한 종래 풍력발전기는 도 1에 도시된 바와 같이, 타워의 상부에 회전 가능하게 설치된 동체와, 상기 동체의 선단에 설치되어 바람에 의해 회전하는 블레이드와, 상기 블레이드의 회전력을 증속시키기 위한 증속기 등의 기어박스와, 상기 기어박스에서 종속된 회전력을 전기적 에너지로 변환하는 발전기 등으로 구성되어 있다.Such a conventional wind power generator, as shown in Figure 1, the body is rotatably installed on the top of the tower, the blade is installed on the front end of the body to rotate by the wind, an increaser for increasing the rotational force of the blade, etc. It consists of a gearbox, and a generator for converting the rotational force dependent on the gearbox into electrical energy.
상기와 같이 구성된 풍력발전기는 바람에 의해 블레이드가 회전하면, 이의 회전력이 기어박스를 통해 증속된다.When the wind turbine is configured as described above when the blade is rotated by the wind, its rotational force is increased through the gearbox.
그리고 발전기에서는 증속된 회전력을 통해 전기 에너지를 발생하며, 이 전기 에너지는 축전장치 등에 인가되어 축전되거나 수요자에게 직접 인가된다.In the generator, electric energy is generated through the increased rotational force, and the electric energy is applied to power storage devices or the like to be stored or directly applied to the consumer.
그러나 상기 수평축 풍력발전기는 블레이드에서 발전기까지 회전토크 전달 경로가 짧아 전달 효율이 좋은 이점은 있으나, 동체 내부에 발전기 등이 탑재되어 무거워짐에 따라 풍향에 따라 신속한 요(yaw) 동작이 어렵고, 동체가 일정횟수 이상 회전하면 풍력발전기가 동작이 정지함과 동시에 꼬인 케이블을 원래 위치로 풀어주어야 하는 문제가 있다.However, the horizontal axis wind power generator has the advantage of good transmission efficiency because the rotational torque transmission path from the blade to the generator is short, but as the generator is mounted inside the fuselage, it is difficult to quickly yaw according to the wind direction, and the fuselage is If the wind turbine rotates more than a certain number of times, the wind turbine stops operating and at the same time there is a problem in that the twisted cable must be released to its original position.
또한, 상기 동체 내부에 발전기가 탑재되어 냉각 및 유지보수 등이 불편하고, 강풍 등으로 인한 비상시 발전기의 과부하 등 시스템 보호를 위해 날개부의 피치제어를 통한 완전 정지로 발전이 불가능한 문제가 있었다.In addition, since the generator is mounted inside the fuselage, it is inconvenient for cooling and maintenance, and there is a problem in that power generation is impossible due to complete stop by controlling the pitch of the wing to protect the system such as overload of the generator in case of emergency due to strong wind.
그리고 수직-수평축 통합형 풍력발전기(듀얼 로터방식)는 메인 블레이드의 중앙부분을 통과하는 풍력을 보조블레이드에서 토크 발생에 이용함으로써, 단면적 당 풍력의 이용률이 향상되는 이점은 있으나, 메인 블레이드 및 보조 블레이드의 회전방향이 반대이므로 이에 따른 블레이드 제작이 어렵고, 메인 블레이드 및 보조 블레이드의 토크가 일정하게 합성되도록 각각의 피치제어가 정밀하게 이루어져야 하지만 실질적으로 완벽한 제어가 어렵다.In addition, the vertical-horizontal axis integrated wind power generator (dual rotor type) uses wind power passing through the central portion of the main blade for generating torque in the auxiliary blade, thereby improving the utilization of wind power per cross-sectional area. Due to the opposite direction of rotation, it is difficult to manufacture the blade accordingly, and each pitch control must be precisely made so that the torques of the main blade and the auxiliary blade are uniformly synthesized, but it is difficult to control the perfect.
상기와 같은 문제점을 해결하고자 본 발명의 풍력발전기는 날개가 회전하여 이면이 됐을 경우 상하 날개 모두에 바람이 부딪쳐 날개가 회전되지 않고 풍력이 상쇄되는 것을 예방하기 위한 고정바람막이를 형성하여 줌으로써, 한 방향으로 바람을 유도하여 적은 바람에도 항시 날개가 연속적으로 회전되어 일정한 동력을 얻을 수 있는 풍력발전기를 제공함에 목적이 있다.In order to solve the above problems, the wind power generator of the present invention forms a fixed windscreen for preventing wind from colliding with the wind when both the upper and lower blades are rotated when the wing is rotated to the rear side, thereby preventing the wind from rotating. The purpose of the present invention is to provide a wind power generator that can obtain constant power by continuously rotating the blades at all times even by inducing wind.
또한, 태풍 또는 강풍이 불어올 경우, 날개에 불어오는 강풍을 고정바람막이와 상기 고정바람막이의 상방으로 상승하는 승강바람막이에 의해 차단함으로써, 강풍에 의한 풍력발전기의 파손을 예방하여 내구성을 극대화할 수 있다.In addition, when a typhoon or a strong wind blows, by blocking the strong wind blowing on the wings by the fixed windshield and the lifting windshield rising above the fixed windshield, it is possible to maximize the durability by preventing damage to the wind turbine caused by the strong wind. .

이때, 상기 고정바람막이(70)의 상단부 후면에는 지지턱(70a)이 형성되고, 상기 승강바람막이(80)의 상단부 및 하단부 전면에는 상기 지지턱(70a)에 걸려 회전을 멈추게 하는 걸림턱(80a,80b)이 형성된다.At this time, the support jaw (70a) is formed on the rear of the upper end of the fixed windshield 70, the locking jaw (80a) to stop the rotation by hanging the support jaw (70a) on the front of the upper end and the lower end of the lifting windshield (80) 80b) is formed.
즉, 상기 승강바람막이(80)가 상방으로 회전시 하단부의 걸림턱(80b)이 상기 지지턱(70a)에 걸려 회전을 멈추고, 상기 승강바람막이(80)가 하방으로 회전시 상단부의 걸림턱(80a)이 상기 지지턱(70a)에 걸림으로써 더 이상 하방으로 회전되지 못하고 상기 고정바람막이(70)의 후측에 위치한다.That is, when the lifting windshield 80 rotates upward, the locking jaw 80b of the lower end is caught by the support jaw 70a to stop the rotation, and when the lifting windshield 80 rotates downward, the locking jaw 80a of the upper windshield 80 is rotated downward. ) Is no longer rotated downward by the support jaw (70a) is located on the rear side of the fixed windshield (70).
상기 승강바람막이(80)는 상기 고정축(20a) 외에 상기 수평회전축(30)의 양단부에 베어링 결합하여 상기 날개(10)의 전방에서 상하방향으로 회전될 수 있다.The lifting windshield 80 may be rotated in the vertical direction from the front of the blade 10 by bearing coupling to both ends of the horizontal rotation shaft 30 in addition to the fixed shaft (20a).
따라서 본 발명의 풍력발전기는, 평상시 상기 고정바람막이(70)에 의해 상기 수평회전축(30)보다 상측에 위치하는 날개(10)로 바람이 전달되어 회전하게 함으로써, 상기 수평회전축(30)의 상하측에 위치하는 날개(10)가 동시에 바람에 부딪힘으로써 힘의 평형에 의해 회전되지 않고 멈추는 것을 예방하며, 태풍 또는 강풍이 불어 올 경우에는 상기 승강바람막이(80)가 상기 고정바람막이(70)의 상방으로 상승하여 상기 수평회전축(30)보다 상측에 위치하는 날개(10)의 전방으로 불어오는 바람을 차단함으로써 강풍에 의해 날개(10) 및 기타 장치가 파손되는 것을 예방하는 현저한 효과를 갖는다.Therefore, the wind power generator of the present invention, by the wind is usually transmitted to the blade 10 located above the horizontal rotating shaft 30 by the fixed windshield 70, the upper and lower sides of the horizontal rotating shaft 30 Wings 10 located in the at the same time to prevent the wind does not rotate by the rotation of the balance by hitting the wind, and when the typhoon or strong wind blows the lifting windshield 80 above the fixed windshield 70 By rising and blocking the wind blowing in front of the wing 10 located above the horizontal axis of rotation 30 has a significant effect of preventing damage to the wing 10 and other devices by strong wind.
