파력 발전장치Wave power generator
본 발명은 파력 발전장치에 관한 것으로서, 더욱 상세하게는, 부력체의 상승 운동과 중량체의 하강 운동을 통해 운동 전달부재가 좌우측으로 이동할 때 발생하는 직선 왕복운동을 운동변환장치가 회전운동으로 변환시켜 그 회전력을 발전기에 전달함으로써, 발전기를 지속적으로 작동시킬 수 있도록 하는 파력 발전장치에 관한 것이다.The present invention relates to a wave power apparatus, and more specifically, conversion increase exercise and weight when through falling motion is the motion transmission member moves to the left and right movement to linear reciprocation generated conversion apparatus of the body of the buoyancy body is a rotational movement The present invention relates to a wave power generating device capable of continuously operating the generator by transmitting the rotational force to the generator.
최근 들어, 조수간만의 차를 이용하여 전기를 얻는 조력발전과, 바닷물의 빠른 유속을 이용하여 전기를 얻는 조류발전 및 파도의 물결을 이용하여 전기를 얻는 파력발전이 주목받고 있다.In recent years, tidal power generating electricity by using the tidal wave difference, tidal power obtaining electricity by using the high speed of the sea water, and wave power generating electricity using the wave of the wave have been attracting attention.
*특히, 파력발전은, 끊임없이 발생되는 파도의 물결을 이용하여 전기에너지를 생산하는 기술이므로, 가장 안정적인 에너지를 얻을 수 있다는 점에서 장점이 있다.In particular, wave power generation is a technology for producing electrical energy by using waves of waves that are constantly generated, there is an advantage in that the most stable energy can be obtained.
이러한 파력발전은 다양한 형태로 개발되고 있다. 종래의 파력발전장치들은, 파도의 출렁임에 따라 상하 운동하는 부력체와, 부력체의 상,하운동을 회전운동으로 바꿔주는 운동변환수단과, 운동변환수단으로부터 전달되는 회전운동을 전기에너지로 바꿔주는 발전기를 포함하여 구성된다.Such wave power is being developed in various forms. Conventional wave power generators, buoyancy body to move up and down as the wave ripples, the movement conversion means for converting the up and down movement of the buoyancy body to rotational movement, and the rotational movement transmitted from the movement conversion means into electrical energy The state is configured to include a generator.
이러한 기술은 부력체를 통해 파도의 상,하운동에너지를 획득한 다음, 획득한 상하 운동에너지를 회전운동으로 바꿔주고, 바꿔진 회전운동을 다시 발전기를 이용하여 전기에너지로 변환시켜준다. 따라서 최종적으로 전기에너지를 얻을 수 있다.This technology obtains the up and down kinetic energy of the wave through the buoyancy body, and then converts the obtained up and down kinetic energy into rotational motion, and converts the changed rotational motion back into electrical energy using a generator. Thus, finally, electrical energy can be obtained.
그런데, 이러한 종래의 파력 발전 장치들은, 파도의 상하 운동에너지만을 주로 이용하는 구조이므로, 발전효율이 낮다는 단점이 지적되고 있다.By the way, since the conventional wave power generators mainly use only the vertical kinetic energy of the wave, it is pointed out that the power generation efficiency is low.
특히, 파도의 파고(波高)가 낮을 경우에는, 파도에서 발생되는 상,하 운동에너지가 매우 작아지므로, 발전효율이 더욱 낮아진다는 문제점이 있으며, 그 결과, 전기 공급이 안정적이지 못하다는 결점이 지적되고 있다.In particular, when the wave height is low, the up and down kinetic energy generated by the wave is very small, there is a problem that the power generation efficiency is further lowered, as a result, the drawback that the electricity supply is not stable It is becoming.
그리고, 파력 발전은 작동원리에 따라 가동물체형, 진동수주형, 월파형이 있고, 설치형태에 따라 착저식, 부유식으로 구별된다. In addition, the wave power generation has an animal body type, a frequency column type, a monthly wave type according to the principle of operation, and is classified into a landing type and a floating type according to the installation type.
상기한 가동물체형의 파력발전은 수면의 움직임에 따라 민감하게 반응하도록 발명된 기구에 크고 작은 물결에너지를 직접 전달함으로써, 기구의 움직임을 전기 에너지로 변환하는 방식이다. 크고 작은 물결에너지를 직접적으로 흡수하므로 에너지 변환 효율은 상대적으로 유리하지만 물결에너지가 직접 기구에 작용하므로 물결에 의한 외력을 견뎌야 한다는 점에서 구조적인 안전성이 취약한 단점이 있다. The wave power generation of the animal body type is a method of directly and largely transmitting wave energy to the device invented to react sensitively to the movement of the water, thereby converting the movement of the device into electrical energy. The energy conversion efficiency is relatively advantageous because it directly absorbs large and small wave energy, but structural safety is weak in that the wave energy acts directly on the apparatus and thus must withstand external forces caused by the wave.
진동수주형 파력 발전은 워터칼럼 내부로 유입된 크고 작은 물결에너지에 의하여 생기는 공간의 변화를 내부공기의 유동으로 변환하고, 이를 유도관으로 유입시켜 입사파가 장치의 전면에서 반사되면 중복파가 형성되도록 하며, 상기 중복파의 형성 시 수면의 상부 노즐부에 공기의 흐름이 발생하는 원리를 이용해 유도관 내에 설치된 터빈을 공기로 회전시켜 전기를 얻는 방식이다. Frequency-driven wave power generation converts the space change caused by the large and small wave energy introduced into the water column into the flow of internal air, and introduces it into the induction pipe so that an overlapping wave is formed when the incident wave is reflected from the front of the device. In addition, by using the principle that the air flow occurs in the upper nozzle portion of the water surface when forming the redundant wave is a method of obtaining electricity by rotating the turbine installed in the induction pipe with air.
월파형 파력 발전은 크고 작은 물결의 진행방향 전면에 사면 벽을 두고 운동에너지에 의해 크고 작은 물결이 사면 벽을 넘어서게 됨으로써 발생하는 수위 차를 이용하여 저수지의 하부로 저장된 해수를 배출시켜서 통로 하부의 수차터빈이 발전하도록 하는 방식이다. The wave wave power generation has a slope wall in front of the direction of the big and small waves and discharges the seawater stored in the lower part of the reservoir by using the water level difference generated by the large and small waves crossing the slope wall by the kinetic energy. It's a way to make turbines generate power
또한, 가동물체형에서 부력체를 이용한 파력 발전은 파도 발생시 나타나는 물결의 높낮이에 따라 상하 운동을 하는 부력체에 연결된 운동 전달부재를 통해 발전기에 전달되는 운동에너지를 이용하여 발전기를 작동시킴으로써 발전하는 방법이다. In addition, the wave power generation using buoyancy body in the animal body type is generated by operating the generator using the kinetic energy transmitted to the generator through the motion transmission member connected to the buoyancy body to move up and down according to the height of the wave appearing when the wave occurs to be.
한편, 부력체를 이용한 파력 발전장치에서 부력체와 발전기는 운동에너지를 용이하게 전달할 수 있는 로프, 와이어, 케이블 등의 운동 전달부재로 연결된다. On the other hand, in the wave power generator using a buoyancy body buoyancy body and the generator is connected to the movement transmission member, such as rope, wire, cable that can easily transfer the kinetic energy.
운동 전달부재는 파고의 높이나 태풍 기타 환경변화에 의하여 수시로 바뀌는 파도의 운동에너지에 따라 부력체의 상승 운동에너지를 발전기의 동력원으로 사용할 수 있도록 발전기에 제공한다. The motion transmission member provides the generator to use the rising kinetic energy of the buoyant body as a power source of the generator according to the wave energy that is frequently changed by the height of the wave height, typhoons or other environmental changes.
이러한 종래의 운동 전달부재는 부력체의 하강시 이완되는데, 이완 상태가 계속되면 부력체의 상승에 따른 운동에너지를 발전기에 즉시 전달할 수 없게 된다.Such a conventional kinetic transmission member is relaxed when the buoyancy body is lowered, it is impossible to immediately transfer the kinetic energy according to the rise of the buoyancy body to the generator.
이에 따라 종래의 파력 발전장치에는 부력체의 하강 시 이완상태가 되는 운동 전달부재를 미리 감기 위하여 권선부재가 설치되어 있다. Accordingly, the conventional wave power generator is provided with a winding member for pre-winding the motion transmission member that is in a relaxed state when the buoyancy body is lowered.
권선부재는 발전기의 작동과는 별도로 공급되는 에너지를 사용하여 운동 전달부재를 감도록 되어 있기 때문에 전기에너지를 더 낭비하게 되는 문제점이 있다. Since the winding member is configured to wind the motion transmission member by using energy supplied separately from the operation of the generator, there is a problem in that the electric energy is further wasted.
또한, 종래의 파력 발전장치는, 부력체가 하강하는 경우 운동 전달부재가 이완상태에 있기 때문에 발전기를 작동시킬 수 없고, 부력체가 상승하는 경우에만 발전기를 작동시킬 수 있기 때문에 효율적인 발전을 할 수 없는 문제점이 있다. In addition, the conventional wave power generator cannot operate the generator because the motion transmission member is in a relaxed state when the buoyancy body is lowered, and it is impossible to efficiently generate power since the generator can be operated only when the buoyancy body is raised. There is this.

그리고 도 6은 원웨이 클러치가 내장된 상기 제1,2 스프로킷(47a)(47b)과 동일한 기능을 하는 래치볼트 기어(47L)를 설치한 도면이다.FIG. 6 is a view showing a latch bolt gear 47L having the same function as the first and second sprockets 47a and 47b in which a one-way clutch is incorporated.
상기 래치볼트 기어(47L)는, 도시하지 않은 힌지핀과 탄성부재에 의하여 기어판(P)의 둘레에 조립되는 기어 치(T)가 기어판(P) 내부에 접힐 수 있도록 설치된다. The latch bolt gear 47L is installed so that the gear tooth T assembled around the gear plate P can be folded inside the gear plate P by a hinge pin and an elastic member (not shown).
래치볼트 기어(47L)는, 상기 제1,2스프로킷(47a)(47b)처럼 동일 작용을 하도록 운동변환장치(40)내에 제1,2 래치볼트 기어(47La)(47Lb) 2개가 설치된다.The latch bolt gear 47L is provided with two first and second latch bolt gears 47La and 47Lb in the motion converter 40 so as to act in the same manner as the first and second sprockets 47a and 47b.

이하, 상기와 같은 본 발명의 파력 발전장치의 작동관계를 설명한다.Hereinafter, the operation relationship of the wave power generator of the present invention as described above.
먼저, 운동 전달부재(20), 운동변환장치(40), 발전기(70) 및 중량체(60)가 수용되는 본체(4)가 해변에 설치된다.First, the body 4, in which the motion transmission member 20, the motion converter 40, the generator 70, and the weight body 60 are accommodated, is installed on the beach.
그리고 운동변환장치(40)에 연결되는 와이어, 로프, 케이블, 체인 중 하나 또는 두가지를 연결하여 형성되는 운동 전달부재(20)는 해저 고정물(30)에 의해 바다의 해저까지 연장 설치된다. And the motion transmission member 20 is formed by connecting one or two of the wire, rope, cable, chain connected to the motion converter 40 is installed to extend to the sea bottom by the seabed fixture (30).
해저 고정물(30)에 거치되는 운동 전달부재(20)에는 부력체(10)가 연결된다.부력체(10)는 파고에 의하여 상하 운동을 하도록 설치된다. The buoyancy body 10 is connected to the movement transmission member 20 mounted on the seabed fixture 30. The buoyancy body 10 is installed to vertically move by digging.
상기한 바와 같이 파력 발전장치(2)가 설치되면, 부력체(10)는 해수면에 떠 있고 운동 전달부재(20)를 통해 중량체(60)의 하중을 받게 된다. 여기서 부력체(10)는 중량체(60)의 하중을 받지만 해저로 가라않지 않고 해수면에 떠 있도록 설치된다. As described above, when the wave power generator 2 is installed, the buoyancy body 10 floats on the sea surface and receives the load of the weight body 60 through the motion transmission member 20. Here, the buoyancy body 10 is installed so as to float on the sea surface without receiving a load of the weight body 60, but does not go to the sea floor.
그리하여 상기 부력체(10)가 해수면에 떠 있다가 파력에 의해 상승하면, 부력체(10)는 상승하면서 운동 전달부재(20)를 당기게 된다. Thus, when the buoyancy body 10 floats on the sea surface and rises due to the wave force, the buoyancy body 10 is pulled up while pulling the movement transmission member 20.
부력체(10)에 의하여 당겨지는 운동 전달부재(20)는 운동변환장치(40)내에서 우측으로 이동하게 된다. 즉, 연결줄(24)에 연결된 체인(22)이 운동변환장치(40)내에서 우측으로 이동하게 된다. The motion transmission member 20 pulled by the buoyancy body 10 is moved to the right in the motion converter 40. That is, the chain 22 connected to the connecting line 24 is moved to the right in the motion converter 40.
그리고, 부력체(10)의 상승으로 운동 전달부재(20)가 우측으로 이동할 때 중량체(60)는 중량체 가이드(66)를 따라 상승하고, 운동변환장치(40)내에서는 체인(22)의 이동으로 체인(22)에 치합되어 있는 스프로킷 기어부(45)들은 회전하게 된다.Then, when the motion transmission member 20 moves to the right due to the rise of the buoyancy body 10, the weight body 60 rises along the weight body guide 66, and the chain 22 in the motion conversion apparatus 40. The sprocket gear parts 45 engaged with the chain 22 are rotated by the movement of.
이때, 스프로킷 기어부(45)의 제1기어부(45a)는 원웨이 클러치의 결합으로 제1 스프로킷(47a)이 체인(22)에 의하여 반시계 방향으로 회전하게 된다. At this time, the first gear portion 45a of the sprocket gear portion 45 rotates the first sprocket 47a counterclockwise by the chain 22 by engagement of the one-way clutch.
원웨이 클러치 작용으로 제1 스프로킷(47a)에 결합된 중심축(46a)은 제1 스프로킷(47a)을 따라 회전하게 된다. 중심축(46a)의 회전으로 하단에 설치된 제1동력전달기어(49a)는 역회전하는 종동기어(44)와 치합되어 연결된 기어박스(42)에 정방향 회전력을 전달하게 된다. The central shaft 46a coupled to the first sprocket 47a by the one-way clutch action rotates along the first sprocket 47a. The first power transmission gear 49a installed at the lower end by the rotation of the central shaft 46a is engaged with the driven gear 44 which rotates in reverse to transmit the forward rotational force to the connected gear box 42.
즉, 부력체(10)의 상하운동으로 발생된 회전력이 기어박스(42)를 통해 발전기(70)에 전달되면 발전기(70)는 작동하여 발전을 하게 된다. That is, when the rotational force generated by the vertical movement of the buoyancy body 10 is transmitted to the generator 70 through the gear box 42, the generator 70 is operated to generate power.
이때, 제2기어부(45b)는 제2 스프로킷(47b)이 체인(22)에 의하여 시계 방향으로 회전하기 때문에 원웨이 클러치가 해제된 상태가 되어 공회전하게 된다. At this time, since the second sprocket 47b rotates clockwise by the chain 22, the second gear portion 45b is in a state where the one-way clutch is released and idles.
따라서 제2 스프로킷(47b)이 공회전 함에 따라 중심축(46b) 하단에 연결된 제2동력전달기어(49b)는 종동기어(44)와 치합되어 회전하지만 운동 에너지가 전달되지 않기 때문에 공회전만 하게 된다. Therefore, as the second sprocket 47b is idling, the second power transmission gear 49b connected to the lower end of the central shaft 46b is engaged with the driven gear 44 to rotate, but only idling because kinetic energy is not transmitted.
그리고 파도가 낮아짐에 따라 부력체(10)가 하강하면, 운동 전달부재(20)에 중량체(60)의 하중이 즉시 작용하게 된다. 이때, 중량체(60)는 부력체(10)가 하강한 만큼 이완된 운동 전달부재(20)를 당기게 된다. And when the buoyancy body 10 is lowered as the wave is lowered, the load of the weight body 60 to the motion transmission member 20 immediately acts. At this time, the weight 60 is pulled by the movement transmission member 20 is relaxed as the buoyancy body 10 is lowered.
