기존의 화석 에너지 자원은 점차 고갈되어갈 뿐만 아니라, 지구환경을 오염시키기 때문에 오래전부터 인류는 고갈되지 않고 환경을 오염시키지 않는 청정대체에너지개발을 위하여 많은 노력을 기울이고 있다. 이러한 청정 대체 에너지로는 태양에너지, 바이오에너지, 풍력, 소수력, 연료전지, 석탄의 액화 및 가스화, 해양에너지, 폐기물에너지 및 그 외에도 지열, 수소, 석탄에 의한 물질을 혼합한 유동성 연료 등이 대체에너지원으로 거론되고 있다. 특히 태양력이나 조력, 풍력 등의 자 연에너지 개발을 통한 대체에너지원의 발굴에 관심이 집중된다.Existing fossil energy resources are gradually exhausted, and since they pollute the global environment, mankind has been making efforts to develop clean alternative energy that has not been exhausted and does not pollute the environment for a long time. Such clean alternative energy sources include solar energy, bioenergy, wind power, hydropower, fuel cells, liquefaction and gasification of coal, marine energy, waste energy, and other fuels including geothermal, hydrogen, and coal-based fluids.

조력(潮力)발전은 조수간만의 차이에 의한 외해와 호수의 수위 차를 이용하는 원리로, 본 발명은 우리나라 서해안의 시화호, 새만금, 가로림만, 천수만 등에서 연안의 매립이나 간척지 개발에 의해 형성되는 호수의 경우에서와 같이, 방조제를 중심으로 외해 수위는 시간에 따라 상하로 수 미터(m)씩 변화하고, 반면에 호수 내의 수위는 인근으로의 홍수나 범람을 피하기 위해 특정 관리수위 이하로 유지되어야 하는 경우에 적용될 수 있다.Tidal power generation is the principle of using the difference between the water level of the sea and the lake due to the difference between tides. The present invention relates to a lake formed by reclamation of land or reclaimed land at the shore of Sihwa Lake, Saemangeum, Garorim Bay, and Cheonsu Bay, etc. As is the case, the offshore water level, which is centered on the dike, changes several meters (m) up and down over time, while the water level in the lake must be kept below a certain management level to avoid flooding or flooding to nearby areas. Can be applied to

일반적으로 수력을 이용한 발전장치는 실용신안 등록 제 0352241 호, 제 0340631 호, 제 0339098 호, 공개특허공보 2004-0033161 호 등과 같이 원통형 수차를 이용하거나, 공개특허공보 2004-0033160 호, 1999-0080153 호 및 2002-0066123호와 같이 원통형 수차 대신 프로펠러 처럼 생긴 임펠러를 이용한 임펠러식 수차를 이용하여 발전기를 구동함으로써, 에너지를 생성시키고 있었다. In general, a hydroelectric power generation apparatus uses cylindrical aberrations, such as Utility Model Registration Nos. 0352241, 0340631, 0339098, JP 2004-0033161, or JP 2004-0033160, 1999-0080153. And 2002-0066123, by using an impeller-type aberration using an impeller shaped like a propeller instead of a cylindrical aberration, energy was generated.

그러나, 상기와 같이 임펠러식 수차를 이용할 경우, 임펠러에서 발생한 수평회전력을 이용하여 부유체나 고정구조물 위의 발전기를 구동하자면 수평회전력을 수직회전력으로 바꾸어야 하는데, 회전력의 방향을 바꾸는 치차장치가 고가이고, 동력전달 효율이 감소되며 또한 유지보수가 어려운 문제점이 있었다. 특히 우리나라 남해안 지역처럼 조류의 방향이 바뀌면 임펠러의 전면이 조류가 오는 방향으로 향하도록 방향을 바꾸어 주어야 하는데 임펠러의 경우 그 방향을 변경하기는 매우 곤란하였다. However, in the case of using the impeller aberration as described above, when driving the generator on the floating body or the fixed structure using the horizontal rotational power generated from the impeller, the horizontal rotational power should be changed to the vertical rotational power. In addition, the power transmission efficiency is reduced and the maintenance is difficult. In particular, if the direction of the algae changes, as in the south coast of Korea, the front of the impeller had to be changed to face the direction of the algae, but it was very difficult to change the direction of the impeller.

또한, 원통형 수차를 이용하는 경우, 공개특허공보 10-2004-0033161 호와 같 이, 부유체나 고정구조물 하부에 수직으로 설치된 다수의 수직원통형 수차와, 상기 수직원통형 수차에 발전효율을 향상시키기 위해 선택적으로 링크되는 종속기어와, 상기 종속기어와 연결되거나 수직원통형 수차에 직결되는 발전기로 구성되어 있어, 원통형 수차의 회전력을 그대로 발전기에서 전달받아 에너지 생성효율을 향상시키는 것도 있으나, 이와 같은 종래의 원통형 수차는 수직원통형 수차의 위치가 고정되어 있어, 조류에너지를 효율적으로 이용할 수 없는 문제점이 있었다. In addition, when using a cylindrical aberration, as shown in Korean Patent Laid-Open Publication No. 10-2004-0033161, a plurality of vertical cylindrical aberrations vertically installed below the floating body or the fixed structure, and selective to improve power generation efficiency in the vertical cylindrical aberrations. It consists of a subordinate gear linked to the, and the generator connected to the subordinate gear or directly connected to the vertical cylindrical aberration, and receives the rotational force of the cylindrical aberration as it is from the generator to improve the energy generation efficiency, but such a conventional cylindrical aberration Since the position of the vertical cylindrical aberration is fixed, there is a problem that can not use the tidal energy efficiently.

물론, 조류에너지를 효율적으로 이용하기 위하여, 발전 장치와 원통형 수차를 부유체에 연결하여 원통형 수차가 일정한 높이를 유지하도록 한 것도 있으나, 이와 같은 부유체 연결 원통형 수차를 이용한 조류력 발전장치는 부유체의 건조에 비용이 발생하며, 거대한 부유체로 인하여 하중이 추가 발생하며, 부유체를 계류시키기 위한 별도의 장치로 인하여 그 설치비용이 증가되고, 부유체의 이동범위 발생에 따른 설치공간의 확보에 곤란한 점이 있는 등 여러가지 문제점이 있었다. Of course, in order to efficiently use algae energy, there is a case that the cylindrical aberration to maintain a constant height by connecting the generator and the cylindrical aberration to the floating body, the algae power generation device using a floating body connected cylindrical aberration such as floating body Cost of drying, additional load is generated due to the huge floating body, the installation cost is increased due to a separate device for mooring the floating body, difficult to secure the installation space due to the movement range of the floating body There were various problems such as the point.

본 발명은 상기와 같은 문제점을 해소하기 위한 것으로, 그 목적은 고정구조물에 부력통을 구비한 수차와 수차축을 요철결합에 의해 연결하여 수차가 수차축을 따라 미끄러짐 운동 및 회전운동을 병행하도록 하여, 조수간만의 차에 따른 수위변동에 따라 수차의 위치가 조류흐름이 가장 강한 수면근처에 위치하도록 하여, 수위변동에 따른 유속 변화에 대응하여 발전효율을 최대화할 수 있는 조류력 발전을 위한 수차 축을 따라 미끄러지는 부력통이 장착된 자가 부양식 수차장치를 제공하는 것이다. The present invention is to solve the above problems, the object is to connect the aberration and the aberration shaft having a buoyancy cylinder to the fixed structure by the concave-convex coupling so that the aberration in parallel with the sliding motion and rotational movement along the aberration shaft In addition, the aberration axis is positioned near the surface where the tidal flow is the strongest according to the water level fluctuation due to the difference between tidal tides. It is to provide a self-sustaining aberration device equipped with a buoyancy buoy sliding along.

이와 같이 본 발명은 수차의 위치를 조수 간만에 따른 수위변화에 상관없이 조류의 흐름이 가장 강한 수면근처에 항시 유지시킬 수 있어, 고속의 조류흐름을 이용한 조류력 발전효율을 향상시킬 수 있다. As described above, the present invention can maintain the position of the aberration at any time near the surface of the strongest tidal flow regardless of the water level change according to tidal tides, thereby improving the tidal current power generation efficiency using a high speed tidal flow.

또한, 본 발명은 부력통을 구비한 수차와 수차축을 요철연결하여, 수차의 회전력이 수차축에 그대로 전달되면서 수차축을 따라 수차가 수직으로 미끄럼 이동될 수 있어, 수위에 따른 수차의 위치조정뿐만이 아니라 회전력을 손실 없이 전달하는 효과가 있다. In addition, the present invention by connecting the aberration shaft and the aberration shaft having a buoyancy tube, the aberration can be slid vertically along the aberration shaft while the rotational force of the aberration is transmitted to the aberration shaft, position adjustment of the aberration according to the water level In addition, it has the effect of transmitting the torque without loss.

또한, 본 발명은 수차와 부력통이 일체로 설치되어 있어, 조수 간만에 따른 수위변화시, 이에 연동하여 별도의 장비없이 고정식 구조물에 설치된 수차만을 수직 이동 시킬 수 있으며, 이를 통해 수차의 위치가 용이하게 가변될 뿐만 아니라, 수차의 회전력을 향상시킬 수 있다.In addition, the present invention is integrally installed with the aberration and buoyancy tube, when the water level changes according to the tidal tides, in conjunction with this can only vertically move the aberration installed in the fixed structure without additional equipment, through which the position of the aberration easily In addition to being variable, it is possible to improve the rotational force of the aberration.

조수간만에 따른 수위의 변화시, 가이드를 구비한 수차축을 따라 수차(40)가 자가 부상과 하강하여 항시 수면 근처(11)에 일정하게 위치하고, 조수간만의 흐름에 의해 수차가 회전되도록 되어 있다. When the water level changes only during tides, the aberration 40 is constantly positioned near the water surface 11 at all times along with the aberration shaft provided with a guide by self-injury and descending, and the aberration is rotated by only the tidal flow.

상기 수차축(30)은 해저 바닥면(10)에 고정설치된 고정식 구조물(20)의 중앙에 회전가능하도록 상부 및 하부가 각각 베어링 지지되어 수직으로 설치되어 있으며, 상부 끝단이 고정식 구조물(20)의 상부에 위치하는 발전기(50)와 연결되도록 되어 있다. 이때, 상기 발전기와 수차축은 기어연결되거나, 직결되어 있으며, 바람직하게는 발전기와 수차축을 직결시킨다. 상기 발전기와 수차축의 직결연결은 공개특허공보 10-2004-0033161 호에 기재되어 있으므로, 이에 대한 상세한 설명은 생략한다. The aberration shaft 30 is vertically installed with the upper and lower bearings respectively supported so as to be rotatable in the center of the fixed structure 20 fixed to the bottom surface 10, and the upper end of the fixed structure 20 Is connected to the generator 50 located in the upper portion. In this case, the generator and the aberration shaft are geared or directly connected, preferably the generator and the aberration shaft are directly connected. Since the direct connection of the generator and the aberration shaft is described in Korean Patent Laid-Open Publication No. 10-2004-0033161, a detailed description thereof will be omitted.

또한, 상기 수차축(30)은 외주면에 길이방향으로 수직하여 소정높이를 구비하도록 가이드(31)가 돌출형성되어 있으며, 상기 가이드(31)는 부력통(41)을 구비하는 수차(40)에 연결되도록 되어 있다. In addition, the aberration shaft 30 has a guide 31 protruding to have a predetermined height perpendicular to the outer peripheral surface in the longitudinal direction, the guide 31 is in the aberration 40 having a buoyancy cylinder 41 It is supposed to be connected.

즉, 상기 수차축(30)은 상부와 하부가 고정식 구조물(10)에 베어링 지지되고, 상기 베어링 지지된 상부와 하부 사이에 위치하도록 수차축(30)의 외주면에 길이방향으로 수직하여 가이드(31)가 돌출형성되어 있다.
