On the other hand, renewable energy power generation, collectively known as wind power generation, solar power generation, wave power generation, seawater temperature difference power generation, tidal power generation, tidal power generation, etc., is a clean power generation method that does not emit greenhouse gases or pollutants, and its distribution and utilization will expand.

Among renewable energy generation methods, wind power generation, wave power generation, and tidal power generation obtain energy from the kinetic energy of wind, waves, and tidal currents using a continuous rotation type or reciprocating energy weight device, and then undergo intermediate conversion to finally produce electricity. do. Among these, reciprocating energy extraction devices are applied to wave power generation (Pelamis, Oyster, Floating Pendulum Wave Energy Converter, etc.) and Wayugi vibration tidal current power generation (VIVACE, VIVEED, etc.), and are directly connected to a generator or hydraulic conversion for power production. Electric power is produced through the device. When the generator is directly connected, the capacity of the generator and the power converter increases due to the large torque generated during the reciprocating motion, and when it goes through the hydraulic converter, the problem of increased energy loss occurs in the process. The present invention relates to a method for minimizing energy loss and minimizing the capacity of generators and power conversion devices by mechanically converting the energy obtained through a reciprocating energy extraction device into continuous rotational motion using a lever-crank mechanism.

이상과 같은 구조를 포함하는 본 발명의 레버-크랭크를 이용한 재생에너지발전장치는, 도 1을 참조하여 설명한 것과 같은 4개의 레버를 포함하는 레버-크랭크 기구를 이용하여 장치 주변 유체의 유동에 의하여 발생하는 블레이드(50)의 왕복각운동 및 제3 레버(40)의 왕복각운동을 제1 레버(20)의 회전운동으로 전환하고, 제1 레버(20)의 일단부에 설치되는 회전축이 각운동축고정판(5)을 관통하여 발전기(8)의 발전축과 결합되게 함으로써, 발전기(8) 내부의 코일을 회전시켜 전력을 생산할 수 있다. The renewable energy power generation device using a lever-crank of the present invention including the structure described above uses a lever-crank mechanism including four levers as described with reference to FIG. 1 to generate electricity by the flow of fluid around the device. The reciprocating angular motion of the blade 50 and the reciprocating angular motion of the third lever 40 are converted into the rotary motion of the first lever 20, and the rotation axis installed at one end of the first lever 20 is the angular motion axis. By penetrating the fixing plate (5) and being coupled to the power generation shaft of the generator (8), power can be produced by rotating the coil inside the generator (8).
또한, 본 발명의 레버-크랭크를 이용한 재생에너지발전장치의 고정판지지대(1)에는, 고정판지지대(1)의 일면에 대향되는 면 상의 중간 높이에 고정판지지대(1)의 상단 부근과 하단 부근에 각각 결합되는 각운동축고정판(5)의 표면 중간까지 곧게 연장되는 직선형 보강보(3)가 각각 형성됨으로써, 고정판지지대(1) 및 각운동축고정판(5) 사이의 결합력을 공고히 유지되도록 한다. In addition, the fixed plate support (1) of the renewable energy power generation device using the lever-crank of the present invention is located near the upper and lower ends of the fixed plate support (1) at a mid-height on the side opposite to one side of the fixed plate support (1). By forming a straight reinforcement beam (3) extending straight to the middle of the surface of the angular motion axis fixing plate (5) to be coupled, the coupling force between the fixing plate support (1) and the angular motion axis fixing plate (5) is maintained firmly.
이는 유체 유동에 의하여 레버-크랭크를 이용한 재생에너지발전장치에 끊임없이 반복 작용하는 외력에 의하여 고정판지지대(1) 및 각운동축고정판(5) 사이의 결합력이 저하되거나 어느 구성요소가 파손될 가능성을 가능한 범위에서 낮추기 위한 보완적 구성이다. This is to reduce the possibility that the bonding force between the fixing plate support (1) and the angular movement axis fixing plate (5) is reduced or any component is damaged due to the external force that constantly and repeatedly acts on the renewable energy power generation device using the lever-crank due to fluid flow. It is a complementary configuration to lower it.

또한, 각 구성요소들 사이의 길이 관계는 도 1에서 설명한 A, B, C 및 D 사이의 관계와 마찬가지로, 제1 축간거리(a)가 가장 짧고, 제4 축간거리(d)가 가장 길며, a+b < c+d 및 a+d < b+c 와 같은 관계가 성립한다. In addition, the length relationship between each component is similar to the relationship between A, B, C, and D described in FIG. 1, with the first axis-to-axis distance (a) being the shortest and the fourth axis-to-axis distance (d) being the longest, Relationships such as a+b < c+d and a+d < b+c are established.
또한, 도 3(a), 3(b), 3(c)는 제3 레버(40) 및 제3 축간거리(c)의 왕복각운동에 따라 제1 축간거리(a) 및 제1 레버(20)가 회전운동하게 됨을 이해하기 쉽도록, 제3 레버(40)의 왕복각운동 상태를 제3 레버(40)의 좌측단이 도면 방향을 기준으로 최고점, 중간점, 최저점에 이른 상태로 구분하여 각각 도 3(a), 3(b), 3(c)에 도시한 것이다. In addition, Figures 3(a), 3(b), and 3(c) show the first axis distance (a) and the first lever ( To make it easier to understand that 20) rotates, the reciprocating angular motion state of the third lever 40 is divided into a state in which the left end of the third lever 40 reaches the highest point, midpoint, and lowest point based on the direction of the drawing. This is shown in Figures 3(a), 3(b), and 3(c), respectively.

도 7을 참조하면, 하나의 설치기둥(270)에 레버-크랭크를 이용한 재생에너지발전장치 제2 실시예(200)가 여러 대 설치되는 경우의 실시예를 확인할 수 있다. 도 7의 실시예는 1개 설치기둥(270)에 12대의 발전장치가 설치되는 실시예를 보여준다.Referring to FIG. 7, an example can be seen where several second embodiments of the renewable energy power generation device 200 using a lever-crank are installed on one installation pillar 270. The embodiment of FIG. 7 shows an embodiment in which 12 power generation devices are installed on one installation pillar 270.
도 4 내지 7을 통하여 살펴본 각 설치 사례에서와 같이, 레버-크랭크를 이용한 재생에너지발전장치 제1/제2 실시예(100)(200)는 교각 등 인공 구조물에 설치되며, 각 방향에 적어도 1기 이상 복수를 일열로 설치할 수 있다. 또한 재생에너지발전장치를 설치할 때는 해당 구조물의 길이 및 재생에너지발전장치의 크기와 유체의 유속, 요구 발전량 등 관련 조건들을 고려하여 몇 기를 설치할지 결정할 수 있다.As in each installation case examined through FIGS. 4 to 7, the first and second embodiments 100 and 200 of the renewable energy power generation device using a lever-crank are installed on an artificial structure such as a bridge, and at least one in each direction. More than one can be installed in a row. Additionally, when installing a renewable energy power generation device, it is possible to decide how many units to install by considering related conditions such as the length of the structure, size of the renewable energy power generation device, fluid flow rate, and required power generation.
도 8은 본 발명의 바람직한 일 실시예에 따른, 레버-크랭크를 이용한 재생에너지발전장치에 포함되는 기구가 정상 작동하도록 보조하기 위하여 이용되는 제어 개념도이다. Figure 8 is a control concept diagram used to assist the normal operation of a mechanism included in a renewable energy power generation device using a lever-crank according to a preferred embodiment of the present invention.
도 8을 참조하면, 입사되는 재생에너지원이 부족하거나 발전부하가 과도할 경우 레버-크랭크를 이용한 재생에너지발전장치 기구의 발전기가 연결된 회전축이 연속 회전운동이 되지 못하는 현상이 발생되어 정상적인 전력생산이 불가하게 된다. 이러한 점을 해결하기 위하여, ‘기구의 운동 속도가 기 설정된 기준 운동 속도보다 큰가’를 판단한 후, 기구 운동 속도가 설정 운동 속도보다 큰 경우에만 정상작동을 하여 발전을 하는 것으로 표현되어 있다. 본 발명의 레버-크랭크를 이용한 재생에너지발전장치가 정지해 있던 상태에서 유체력이 작용하기 시작하는 초기에는 위와는 달리 기구 운동 속도가 설정 운동 속도에 미치지 못하게 되는데, 이런 경우에는 기구의 움직임에 발전부하를 부가하지 않도록 하여 자연 상태에서 보다 더 빠르게 기구 운동 속도가 기준 운동 속도에 도달할 수 있도록 제어한다.Referring to FIG. 8, when the input renewable energy source is insufficient or the power generation load is excessive, a phenomenon occurs in which the rotating shaft connected to the generator of the renewable energy power generation device mechanism using a lever-crank cannot perform continuous rotation, preventing normal power production. It becomes impossible. In order to solve this problem, it is expressed that after determining ‘whether the movement speed of the device is greater than the preset reference movement speed’, it operates normally and generates power only when the movement speed of the device is greater than the set movement speed. Unlike the above, at the beginning when the fluid force begins to act while the renewable energy power generation device using the lever-crank of the present invention is stationary, the movement speed of the mechanism does not reach the set movement speed. In this case, power generation occurs due to the movement of the mechanism. By not adding a load, the machine movement speed is controlled to reach the standard movement speed faster than in natural conditions.
이상에서, 기구란 유체에 의해 움직임이 발생하는 구성요소들을 지칭하는 표현으로서, 유체에 대한 저항력 작용으로 운동 에너지를 발생시키는 블레이드(50), 블레이드와 결합되어 일정 각도 범위 내에서 병진 운동하는 제3 레버(40) 및 제2 레버(30), 제1 레버(20)를 가리킨다. In the above, the mechanism refers to components that cause movement by fluid, including a blade 50 that generates kinetic energy through the action of resistance to the fluid, and a third device that is combined with the blade and moves in translation within a certain angular range. It refers to the lever 40, the second lever 30, and the first lever 20.
또한, 상술한 바와 같이 기구의 움직임을 일정 속도 범위 이내로 제한하거나 가진력을 더하기 위한 구성으로는 발전기(8)의 회전축의 회전 속도를 감속하거나 가속할 수 있는 것이 구현 비용 및 난이도, 효율성 면에서 바람직하다.In addition, as described above, as a configuration for limiting the movement of the mechanism within a certain speed range or adding exciting force, it is desirable to be able to slow down or accelerate the rotation speed of the rotation axis of the generator 8 in terms of implementation cost, difficulty, and efficiency. .
이와 같이 회전축의 회전 속도 가감속을 위해서는, 도 2,3을 참조하여 설명한 기본 구성에 제어부와 액츄에이터를 추가함으로써, 본 발명의 레버-크랭크를 이용한 재생에너지발전장치를 구성할 수 있으며, 추가 구성은 다음과 같다. 아래에서 회전축은 회전축삽입구(10)에 삽입된다.In order to accelerate and decelerate the rotational speed of the rotating shaft in this way, the renewable energy power generation device using the lever-crank of the present invention can be configured by adding a control unit and an actuator to the basic configuration described with reference to FIGS. 2 and 3, and the additional configuration is As follows. Below, the rotating shaft is inserted into the rotating shaft insertion hole (10).
회전축 주변에 설치되어 회전축의 회전 속도를 측정하는 회전속도계측센서 및 고정판지지대(1) 또는 각운동축고정판(5) 중 어느 한 쪽에 설치되고 회전속도계측센서로부터 회전 속도 측정 결과값을 전달받는 제어부를 구비하고, 회전속도계측센서에서 측정된 회전축의 회전 속도가 사전 설정된 회전 속도보다 큰 경우, 제어부의 제어에 의하여 발전기를 통해 정상적으로 전력생산하고, 회전속도계측센서에서 측정된 회전축의 회전 속도가 사전 설정된 회전 속도보다 작은 경우, 연속 회전운동이 이루어지지 않으므로 제어부의 제어에 의하여 발전부하를 부가하지 않도록 하여 연속 회전운동이 이루어질 수 있도록 회전축에 가속력을 제공한다.A rotation speed measurement sensor installed around the rotation axis to measure the rotation speed of the rotation shaft, and a control unit installed on either the fixing plate support (1) or the angular movement shaft fixation plate (5) and receiving the rotation speed measurement results from the rotation speed measurement sensor. If the rotation speed of the rotation axis measured by the rotation speed measurement sensor is greater than the preset rotation speed, power is normally produced through the generator under the control of the control unit, and the rotation speed of the rotation axis measured by the rotation speed measurement sensor is greater than the preset rotation speed. If it is less than the rotation speed, continuous rotation is not achieved, so no power generation load is added under the control of the control unit, and acceleration force is provided to the rotation shaft to enable continuous rotation.

They must be coated to prevent corrosion, or the materials forming each component must be selected to be suitable for the underwater environment in which they are implemented.
