Abstract

PURPOSE: A braking wing-interlocking type strong wind-adaptive windmill is provided to easily make use of wind power energy by making the windmill safety from a strong wind or strong blast, at low cost. CONSTITUTION: In a braking wing-interlocking type strong wind-adaptive windmill, rotor wings(1) are attached to a rotor(4) and the rotor wings freely rotates on a wing shaft. The initial incidence of the rotor wing is 6 ¯ 15 degrees. The end of a braking wing interlock shaft(8) freely rotates in a hole of the end of a braking wing(9) at a connection point of a braking interlocking shaft(8) and the braking wing, and the connection point is moved right and left by fitting pins. When the rotor, a rotor shaft(6), and the braking wing interlock shaft rotate together by the rotor wings by the wind blown from a wind direction(3) at the proper wind velocity(3.6¯18m/sec), power is transmitted to a generator. If a strong wing is blown, the braking wings are pushed backward and the braking wing interlock shaft connected to the braking wing controls the rake angle of the rotor wings by pulling the rotor wings by a wing-pulling unit(2) while advancing, to avoid the strong wind. Normal rotation is executed through restoration at the proper wind velocity.

Description

제동날개 연동식 강풍적응형 풍차{omitted}Brake Wing Interlocking Strong Wind Adaptation Windmill {omitted}

전세계적으로 화석연료가 고갈 되어 대체에너지 개발이 시급한 때에 풍력에너지 이용을 위하여 많은 연구가 이루어지고 있으며,실제로 대형풍차를 설치하여 많은 량의 전력을 생산하고 있으나,강풍과 돌풍에 안전한 풍차를 만들기 위해서는 고도의 기술과 고액의 제작비가 투입되어야 하는 어려움이 있어 그 보급이 부진한 상태이다.When fossil fuels are depleted all over the world and there is an urgent need to develop alternative energy, many studies are being conducted to use wind energy.In fact, large windmills are installed to produce a large amount of power, but to make windmills safe for strong winds and gusts, It is difficult to supply high technology and high production cost, and its supply is sluggish.

본 발명은 이러한 문제를 해결하기 위하여 강풍과 돌풍에도 안전하게 견딜 수 있는 간단한 원리를 적용하였으며,저렴한 비용으로 강풍적응형 안전 풍차 제작이 가능하도록 하였다.The present invention has applied a simple principle that can safely withstand strong winds and gusts in order to solve this problem, it was possible to manufacture a strong wind-adaptive safety windmill at a low cost.

풍차의 과속회전을 방지하고 강풍시 회전날개의 풍력저항을 최소화하기위하여 지금까지 사용하고 있는 제어방식으로는 다음과 같은 것이 있으나, 방식마다 문제가 있음을 발견하게 된다.In order to prevent over-speed rotation of windmills and to minimize wind resistance of the rotor during strong winds, the following control methods have been used so far, but each method has a problem.

1. 가변축 제어(도 4-가)1. Variable axis control (Fig. 4-A)

강풍을 받은 회전자가 축익(17)에 의해 회전자의 방향을 돌려 강풍을 피하는 방법인데, 이 방식은 아주 작은 풍차에서나 사용할수 있는것이고,규모가 클 경우는 매우 위험한 방식이다.The rotor receives a strong wind to rotate the direction of the rotor by the shaft (17) to avoid the strong wind, this method can be used in very small windmills, if the scale is very dangerous way.

2. 감속 플랩 제어(익단 접히기:spoiler flaps:도 4-나)2. Deceleration flap control (spreader flaps: Fig. 4-B)

회전자의 회전속도가 빨라지면 회전자날개의 끝부분이 분리되면서 풍력저항을 받아 저속회전 하도록 하는 방법인데,이 방법은 부분적으로는 저항을 줄일 수있으나 남아있는 넓은 부분은 그대로 풍력저항을 받고 있기 때문에 강풍을 피하는 방법으로는 미흡하다.When the rotor speed increases, the tip of the rotor blade is separated to receive low-speed wind resistance. This method can partially reduce the resistance, but the remaining wide part is still receiving wind resistance. Therefore, the way to avoid the strong wind is insufficient.

3. 추에 의한 날개 경사 제어(fly ball:governor :도 4-다)3. Wing tilt control by weight (fly ball: governor: Figure 4-d)

회전자 날개마다 추를 장치하여 원심력에 의한 추의 인장력으로 날개의 경사를 바꾸어 강풍을 피하는 방법으로서, 추의 무게가 회전자의 무게를 가중시키는 문제점이 있고, 3 익형의 경우 추 3개가 동시에 작동하지 않기 때문에 경사조정이 늦어지는 날개에는 강한 풍력저항을 받게 되고,따라서 날개의 불균형 때문에 파손위험이 더 커지게 된다.As a method of avoiding strong winds by changing the inclination of the wing by the tension of the weight by centrifugal force by installing the weight on each rotor blade, the weight of the weight adds weight to the rotor, and in the case of three airfoils, three weights operate simultaneously. Because of this, the blades that are slowed down are subject to strong wind resistance, which increases the risk of breakage due to blade imbalance.

4. 나선 이탈식 경사 제어(blade-pitch control :도 4-라)4. Spiral-pitch control (Fig. 4-D)

회전자가 고속 회전할 때 날개가 원심력에 의하여 밖으로 나선을 따라 나가면서 경사각을 이루어 저속회전 하도록하는 방법이다.이 방법 또한 날개마다 같은 속도로 나선을 이탈하지 않기 때문에 늦게 이탈하는 날개는 강풍저항을 더 받게되어 날개간의 불균형으로 풍차가 파손될 위험은 그대로 있다.When the rotor rotates at a high speed, the blades are rotated outward by the centrifugal force to make an inclined angle and rotate at a low speed.In addition, since the blades do not leave the spiral at the same speed for each wing, the wing that leaves later gives more wind resistance. The risk of damaging the windmill due to unbalance between wings remains unchanged.

5. 브레이크 제어5. brake control

자동차 제동방식인 유압식 브레이크에의한 제어방식인데,외부에서 가압할 수 있는 장치가 별도로 있어야 하고 컴퓨터시스템에 의한 고도의 기술과 장비로 운용 되어야 한다.It is a control method by hydraulic brake, which is an automobile braking method, and there must be a separate device that can pressurize externally and be operated with advanced technology and equipment by computer system.

본 발명은 상기와 같은 문제점을 해소하기 위해 저렴한 비용으로 강풍 돌풍에도 안전한 풍차를 만들어 손쉽게 풍력에너지를 이용할 수 있도록 하는데 본 발명의 목적이 있다.The present invention has an object of the present invention to make it easy to use wind energy by making a windmill safe even at high wind gusts at a low cost to solve the above problems.

이와 같은 목적을 달성하기 위하여 본 발명은,전방회전형 풍차에서 바람을 받은 제동날개에 의해 수평으로 전후진하는 제동날개연동축이 회전자축 속에서 회전자축과 함께 회전하도록 제작하여, 강풍시에는 제동날개 연동축이 후진하면서 회전자날개에 연결된 날개당김쇠로 회전자날개를 끌어당겨 회전자날개와 바람 방향이 평행이 되므로서 회전자날개가 강풍을 피해 저속 회전하거나 정지하고,적정 풍속에서는 제동날개의 무게에 의하여 제동날개가 내려오면서 제동날개연동축에 연결 된 날개당김쇠가 회전자날개를 뒤로 밀어 회전자날개 경사각이 복원 되어 다시 회전하도록 하는 것이 특징이다.In order to achieve the above object, the present invention, the braking blade interlocking shaft which moves forward and backward horizontally by the braking blades received by the wind in the forward-rotating windmill to rotate with the rotor shaft in the rotor shaft, braking during strong winds As the wing interlocking shaft reverses, the rotor blade is pulled by the wing tug connected to the rotor blade so that the rotor blade is parallel to the wind direction, so the rotor blade rotates or stops at high wind speed and stops at the proper wind speed. As the braking wing descends by weight, the wing tug connected to the braking wing interlocking shaft pushes the rotor blade back so that the rotor blade tilt angle is restored and rotates again.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

풍차의 종류에는 전방회전형,후방회전형,수직형등이 있으나,본 발명에서는 도 1과 같은 전방회전형을 대상으로 한다.Types of windmills include a forward rotation type, a rear rotation type, a vertical type, and the like, but the present invention is directed to the front rotation type as shown in FIG. 1.

회전자날개(1)는 회전자(4)에 부착하되 날개축(20)에서 자유롭게 돌수 있도록 하고 회전자 날개마다 최초붙임각은 6°~15°가 되도록 한다.제동 날개연동축(8)과 제동날개(9)의 연결점에서는 제동날개(9) 끝 구멍 에서 제동날개연동축(8) 끝 부분이 자유롭게 회전 하도록 만들고 연결점이 좌우로 이동할 수 있도록 양쪽에 핀을 끼운다.The rotor blades 1 are attached to the rotor 4 so that they can freely rotate on the blade shaft 20, and the initial angle of attachment for each rotor blade is 6 ° to 15 °. At the connection point of the braking wing (9), the end of the braking wing linkage shaft (8) rotates freely at the end of the braking wing (9), and pins are inserted at both sides so that the connection point can move left and right.

적정풍속(3.6m ∼18m/초)에서는 바람방향(3)에서 불어오는 바람을 받아 회전자날개(1)에 의해 회전자(4)가 회전자축(6)과 제동날개연동축(8)이 함께 회전할때, 동력은 프리(21)나 톱니로 연결된 발전기에 전달 된다.At the proper wind speed (3.6m to 18m / sec), the rotor 4 receives the wind blowing from the wind direction 3, and the rotor 4 causes the rotor shaft 6 and the brake blade interlocking shaft 8 to rotate. When rotating together, power is transmitted to a free 21 or cogwheeled generator.

강풍(l3m/초 이상) 을 받게 되면 도3 (나)에서와 같이 제동날개(9)가 뒤로 밀리면서 제동날개걸침팔(10)에 의해서 제동날개연동축(8)이 전진하여 날개당김쇠(2)에 연결된 회전자날개(1) 끝을 앞으로 끌어 당긴다.이에 따라,회전자날개 경사각이 커지면서 회전자날개(1)와 바람방향(3)은 평행에 가까워지고,바람은 회전자날개(1)에 압력을 가하지 않고 지나가게 된다.풍속이 낮아지면 제동날개(9)는 자체무게에 의하여 아래로 내려오게 되고 제동날개연동축(8)과 날개당김쇠(2)는 후진하면서 회전자날개(1)의 한쪽 끝을 뒤로 밀어 회전이 가능하도록 경사각을 조절한다.When receiving a strong wind (l3m / sec or more), as shown in Figure 3 (b), the braking wing (9) is pushed backwards, the braking wing interlocking shaft (8) is advanced by the braking wing hook arm (10) and the wing pulls ( Pull the end of the rotor blade (1) connected to 2) forward. Accordingly, as the rotor blade inclination angle increases, the rotor blade (1) and the wind direction (3) are close to parallel, and the wind is the rotor blade (1). When the wind speed decreases, the braking wing (9) comes down by its own weight, and the braking wing linkage shaft (8) and the wing tab (2) move backward while the rotor blade ( Push back one end of 1) and adjust the inclination angle so that it can rotate.

이러한 작동이 반복되어 강풍에도 풍차를 안전하게 유지할 수 잇다.This operation is repeated to keep the windmill safe even in strong winds.

본 발명을 실용화 했을 때,풍차 제작비와 관리비용을 대폭 절감할 수 있고, 강풍에도 풍차를 안전하게 유지할 수 있어,세계적으로 생존의 위협이 되고 있는 고유가 시대에 대체 에너지를 손쉽게 이용 할 수 있는 방법이 될 것으로 기대 된다.When the present invention is put into practical use, windmill manufacturing cost and management cost can be greatly reduced, and the windmill can be safely maintained even in strong winds, and it will be a method to easily use alternative energy in the high oil price era which is a threat to survival worldwide. It is expected to be.
