조력과 파력을 이용한 복합발전장치{Compound Electric Generating Apparatus Using Tidal Power And Wave Power}Compound Electric Generating Apparatus Using Tidal Power And Wave Power}

본 발명은 조수 간만의 차를 이용하는 조력과 파도의 상하운동에너지를 복합적으로 이용하여 전력을 생산할 수 있도록 하는 조력과 파력을 이용한 복합발전장치에 관한 것이다.The present invention relates to a composite power generation apparatus using tidal and wave power to produce electric power by using the tidal energy of the tidal wave and the up and down kinetic energy of the wave.

현대 문명은 전기의 발명과 함께 시작되었다 해도 과언이 아닐 만큼, 전기는 과거로부터 현재에 이르기까지 국가 경제의 기틀이 되는 매우 중요한 에너지 요소이다.It is no exaggeration to say that modern civilization began with the invention of electricity, and electricity is a very important energy element that forms the basis of the national economy from the past to the present.

일반적인 발전방법으로 수력발전, 화력발전, 원자력발전 등을 들 수 있는데, 이러한 발전방법들은 대규모의 발전설비가 필요하고, 화력발전의 경우 발전설비를 가동시키기 위해 엄청난 양의 석유 또는 석탄에너지가 필수적으로 공급되어야 했으므로 석유, 석탄자원이 고갈되고 있는 현 시점에서는 많은 어려움이 예견되고 공해도 큰 문제가 되고 있으며, 원자력발전의 경우는 방사능 유출과 핵폐기물 처리가 심각한 문제점을 안고 있다. 따라서 이러한 일반적인 발전방법보다 저렴하고 안전하고 획기적인 발전방법이 요구되고 있다.Common power generation methods include hydroelectric power generation, thermal power generation, and nuclear power generation. These power generation methods require large-scale power generation facilities, and in the case of thermal power generation, huge amounts of oil or coal energy are required to operate power generation facilities. At the present time when oil and coal resources are depleted, many difficulties are foreseen and pollution is a big problem. In the case of nuclear power generation, radioactive leakage and nuclear waste treatment have serious problems. Therefore, a cheaper, safer and more breakthrough power generation method than the general power generation method is required.

한편, 석유나 석탄자원이 필요 없고 방사능이나 핵폐기물 문제가 없는 발전방법으로는 태양열발전, 파력발전, 조력발전, 풍력발전 등 다양하며, 이 가운데 조수간만의 차이에 따라 조수가 수평이동하는 힘을 이용한 것이 조력발전이고, 파도의 상하운동에너지를 복합적으로 이용하여 전력을 생산할 수 있도록 하는 것이 파력발전이다.On the other hand, there are various power generation methods that do not require oil or coal resources and do not have radioactive or nuclear waste problems such as solar power generation, wave power generation, tidal power generation, and wind power generation. The tidal power generation is used, and the wave power generation is used to produce electric power by using the up and down kinetic energy of waves.

The separate installation requires a lot of installation area, and thus the power generation efficiency is lower compared to the facility investment, and the equipment is not shared because of the separate installation. According to the separate installation, a large amount of time is required for maintenance and other economic problems.

본 발명의 목적은 상기와 같은 문제점을 감안하여 안출된 것으로, 조수 간만의 차를 이용하는 조력과 파도의 상하운동에너지를 복합적으로 이용하여 전력을 생산할 수 있도록 함으로써, 설비투자에 비하여 발전효율이 높고 설치비와 유지보수비를 획기적으로 절감할 수 있도록 하는 조력과 파력을 이용한 복합발전장치를 제공하는 것에 있다.The object of the present invention was devised in view of the above problems, and by using the tidal energy between tides and tidal wave energy up and down to produce electric power, the power generation efficiency and installation cost is higher than facility investment And to provide a composite power plant using tidal and wave power to significantly reduce the cost and maintenance costs.

도 1은 본 발명의 실시예에 따른 조력과 파력을 이용한 복합발전장치의 구성을 개략적으로 예시한 도면이다. 1 is a view schematically illustrating a configuration of a composite power generation apparatus using tidal and wave power according to an embodiment of the present invention.

본 발명의 실시예에 따른 조력과 파력을 이용한 복합발전장치의 전체적인 구성부를 대별하면, 바닷속에 일정길이와 높이로 설치되어 장치 전체를 지지하는 지주(10)와, 상기 지주(10)에 회전가능하도록 설치되며 조수간만의 차이에 따라 조수가 수평 이동하는 힘을 이용하여 전력을 생산하는 조력발전부(20)와, 상기 조력발전부(20)의 상부에 일체로 구비되며 파도의 상하운동에너지를 이용하여 전력을 생산할 수 있도록 하는 파력발전부(30) 및 상기 파력발전부(30)와 조력발전부(20)에서 발전되는 전기를 일정한 상용 주파수의 전압으로 변환시켜 전력사용처로 공급할 수 있도록 하는 전력변환부(40)로 구성된다.When the overall configuration of the composite power generation apparatus using tidal and wave force according to an embodiment of the present invention is roughly divided, the support 10 and the support 10, which is installed at a predetermined length and height in the sea, and rotatable to the support 10 The tidal power generation unit 20 and the tidal power generation unit 20 to produce electric power by using the horizontal movement force of the tidal wave according to the difference between the tidal wave and the tidal power generation unit 20 are integrally provided and the vertical kinetic energy of the waves Wave power generation unit 30 to produce power by using the power to convert the electricity generated in the wave power generation unit 30 and tidal power generation unit 20 to a voltage of a constant commercial frequency to supply to the power usage destination It consists of a converter 40.

조수간만의 차이에 따라 조수가 수평이동하는 힘을 이용하여 전력을 생산할 수 있도록 하는 상기 조력발전부(20)는, 조류의 흐르는 방향에 부응하여 방향전환이 가능하도록 상기 지주(10)에 회전가능하도록 해수이동관(21)을 구비한다. 상기 해수이동관(21)은 조류의 흐름을 안내하는 안내로의 기능을 수행하며, 상기 해수이동관(21)의 양측에는 축지지대(22)가 구비된다.The tidal power generation unit 20 to produce power by using the horizontal movement force of the tide according to the difference between the tidal, the rotatable to the support 10 so as to be able to change the direction in response to the flow direction of the tidal current It is provided with a sea water moving tube (21). The seawater pipe 21 serves as a guide to guide the flow of algae, and both sides of the seawater pipe 21 are provided with shaft supports 22.

상기 해수이동관(21)의 내부에는 상기 축지지대(22)에 의하여 길이 방향으로 길게 회동축(23)이 회전가능하도록 설치되며, 상기 회동축(23)에는 복수의 블레이드(24a)를 통과하는 조수의 흐름에 의하여 회전력을 발생시켜 회동축(23)을 회전시키는 프로펠러(24)를 구비한다.The rotational shaft 23 is rotatably installed in the longitudinal direction by the shaft support 22 in the seawater moving tube 21, and the tide passes through the plurality of blades 24a in the rotational shaft 23.

Figure 112010037230336-pat00002
형 단면 구조를 갖도록 배열함으로써, 해수의 흐르는 방향 즉, 밀물과 썰물에 영향을 받지 않고 오른쪽에서 왼쪽, 혹은 왼쪽에서 오른쪽으로 정/역회전이 가능하여 조류의 흐르는 방향과 무관하게 프로펠러가 회전할 수 있도록 하는데, 상기 블레이드(24a)의 수는 많을수록 효율이 떨어지므로 2엽, 3엽, 6엽 등으로 용도에 맞게 구비하는 것이 바람직하다.2 is a perspective view of a propeller and a blade which are main components of the tidal power generation unit in the composite power generation apparatus using tidal and wave power according to an embodiment of the present invention.

Figure 112010037230336-pat00002
By arranging to have a cross-sectional structure, the propeller can be rotated regardless of the flow direction of the tide because it is possible to forward / reverse from right to left or left to right without being affected by the direction of seawater flow, that is, high and low tide. The more the number of the blades (24a), the lower the efficiency, so it is preferable that the two leaves, three leaves, six leaves, etc. to suit the purpose.

그리고, 프로펠러(24)의 구동에 의하여 회전하는 상기 회동축(23)에는 전력을 생산하는 발전기(25)가 연결수단(26)에 의하여 연결되는데, 상기 연결수단(26)은 설치환경에 적절히 대응하여 기어 또는 벨트를 선택적으로 적용하는 것이 바람직하다. In addition, a generator 25 for generating electric power is connected to the rotating shaft 23 which is rotated by the propeller 24 by a connecting means 26, and the connecting means 26 appropriately corresponds to an installation environment.
