본 발명은 해수의 밀물과 썰물을 이용한 수력발전을 시스템에 관한 것으로 상세하게는 해수의 밀물의 조류를 억제하여 수차를 이용하여 발전하고, 썰물 때도 해수의 흐름을 억제하여 물막이 댐과, 상기의 물막이 댐에 의해서 조절된 해수의 량과 해수의 흐름으로 회전하는 수차를 형성한 발전설비로 구성한 것이다.The present invention relates to a hydroelectric system using the high tide and the low tide of the sea water, and in detail, to suppress the tide of the high tide of the sea water to generate power by using aberration, and to prevent the flow of sea water at low tide, the water barrier dam and the water barrier It is composed of power generation facilities that form aberrations that rotate by the amount of seawater and the flow of seawater controlled by dams.

일반적으로 해수를 이용한 조력발전이 사용되고 있다.Generally, tidal power generation using seawater is used.

상기의 조력발전의 해수의 조수의 간만의 차를 이용하여, 해수의 움직임에 반응하는 수차를 이용하여 발전을 하고 있지만, 이러한 조력발전의 경우 밀물을 저장하였다가 썰물 때 물이 배출되는 수력에 의해 수차를 구동하여 발전하는 것이다.The tidal power of the tidal power of the tidal power generation is generated by using the aberration in response to the movement of the sea water, but in the case of such tidal power generation by storing the high water and the water discharged at low tide It develops by driving aberrations.

그러므로 상기의 조력발전은 썰물 때만 발전시설을 구동할 수 있어, 발전을 위한 시간이 매우 적고, 또한, 댐 내부로 유입되는 밀물을 조력발전에 사용하지 못하므로, 밀물을 저장하는 저장댐의 기능이 미흡한 문제점이 있었다.Therefore, the tidal power generation can only operate the power plant at low tide, so the time for power generation is very small, and also because the high water flowing into the dam is not used for tidal power generation, the function of the storage dam to store the high water There was an inadequate problem.

또한, 밀물을 저장하는 댐막이의 설비가, 매우 힘들고 복잡하여, 댐막이 공사에 많은 경비가 소요되므로, 조력발전 시스템을 구비하는데 많은 어려움이 있었다.In addition, since the installation of the dam barrier for storing high water is very difficult and complicated, and the dam barrier requires a lot of expenses, there are many difficulties in providing an tidal power generation system.

본 발명은 해수의 밀물과 썰물의 구분 없이 발전을 할 수 있도록, 썰물 때에 물을 흘려보내어 수차를 회전의 회전을 통하여 발전하는 조력발전과, 해수의 흐름을 이용한 조류력발전 기능을 가지도록 한 것이다.The present invention is to have the tidal power generation function to generate power through the rotation of the rotation by rotating the water flow at the ebb tide so that power can be developed without distinction between the high and low tide of sea water, and the tidal power power generation using the flow of sea water .

본 발명은 조류력 발전에 필요한 일정 속도를 제공할 수 있도록 하고, 밀물을 저장하는 댐막이 공사를 저렴한 비용으로 설비하도록 한 것이다. The present invention is to provide a constant speed required for tidal power generation, and to install a dam dam for storing high water at low cost.

상기의 같은 문제점을 감안하여, 조수력을 이용하여 조력발전을 구현하는 것으로, 해수의 썰물과 밀물 때 동일하게 조력발전을 할 수 있도록 한 것이다.In view of the above problems, by using tidal power to implement tidal power, it is to enable tidal power generation at the same time when the ebb and tide of sea water.

본 발명은 밀물과 썰물 때 동작하는 수차를 구분하여, 밀물 때에는 밀물 수차에 회전을 증속기로 증속하여 발전기에 동력을 생성하고, 썰물 때에는 썰물 수차에 회전과, 역회전 증속기를 통하여 발전기에 동력을 생성할 수 있도록 하므로, 밀물과 썰물을 함께 이용하여 발전을 하는 것이다.The present invention distinguishes aberrations that operate at high tide and low tide, and when the tide at high tide to increase the rotation to the speed generator to generate power, and at low tide the rotation to the ebb aberration, and to generate power to the generator through the reverse rotation gearbox So you can do it, it is to use the high and low tide together to develop.

본 발명은 상기의 밀물 수차와 썰물 수차를 구비한 물막이용 댐이 구성이, 일정 간격 떨어지게 해수면에 고정한 콘크리트 파일을 형성하고, 상기의 콘크리트 파일 사이에 콘크리트 패널을 적층하는 방법으로 물막이 댐을 형성하고, 상기의 물막이 댐에 밀물과 썰물 때에 달리 동작하는 수문을 형성한 것이다.The present invention forms a concrete pile fixed to the sea level so that the water dam is equipped with the high water aberration and the low tide aberration, a predetermined interval apart, and forming a water dam by stacking the concrete panel between the concrete pile , The water barrier is to form a water gate that operates differently at high and low tide in the dam.

본 발명은 밀물과 썰물을 이용한 조력발전과, 해수의 흐름을 이용한 조류력발전을 하나의 시설로 발전하므로, 많은 량의 발전을 하는 효과가 있는 것이다.In the present invention, tidal power generation using high water and low tide, and tidal power power generation using the flow of seawater are generated as a single facility, so that a large amount of power is generated.

본 발명은 밀물이나 썰물에 큰 수압이 발생하지 않으므로, 적은 경비로 편리하고 간편하게 물막이 댐 공사를 할 수 있어, 해수를 이용한 발전시설을 설비하는 경비를 절감하는 효과가 있는 것이다.Since the present invention does not generate large water pressure in the high tide or low tide, it is possible to conveniently and simply dam dam construction at a low cost, there is an effect of reducing the cost of installing a power plant using sea water.

본 발명은 밀물과 썰물 때에 발전을 일으켜 발전시간을 연장하므로, 많은 량의 에너지를 생산할 수 있어, 석유 에너지 절감하여 자연을 보호하며, 국가 경제발전에 이익을 주는 효과가 있는 것이다. The present invention is to generate power at high tide and low tide to extend the power generation time, it is possible to produce a large amount of energy, to reduce the oil energy to protect nature, and to benefit the national economic development.

일정 간격을 두고 형성되어 해수면에 고정한 콘크리트 파일과, 상기의 콘크리트 파이의 요부에 결합하여 적층 하는 콘크리트 판으로 구성한 물막이 판과, 상기의 물막이 판에는 댐 내부로 해수를 유입하는 유입문과, 댐 외부로 해수를 유출되는 유출문을 각각 형성한 것이다.A water barrier plate composed of a concrete pile formed at regular intervals and fixed to the sea surface, and a concrete plate laminated in combination with the recessed portion of the concrete pie, and the water barrier plate has an inlet door for introducing seawater into the dam and an outside of the dam. Each outflow door is formed to drain the sea water.

이와 같은 본 발명을 상세하게 설명하면 다음과 같다.The present invention will be described in detail as follows.

본 발명의 물막이 댐은 기둥(지주) 역할을 콘크리트 파일과 해수의 흐름을 차단하는 물막이 패널로 구성되는 것이다.The water dam of the present invention is composed of a concrete panel and a water barrier panel to block the flow of seawater to serve as a pillar (holder).

상기의 물막이 패널에는 밀물 때에 해수가 물막이 댐 내부로 유입되도록 개 방하는 B수문과, 썰물 때에 물막이 댐 내부의 유입된 해수의 방수를 위하여 개방하는 A수문이 형성되어 있으며, 만조 때에 물막이 댐 외부의 해수를 물막이 댐 내부로 유입하도록 개방하는 C수문을 형성한 것이다.The water barrier panel is formed with a B gate that opens seawater to flow into the dam at high tide, and an A gate that opens to waterproof the seawater introduced into the dam at low tide. It formed a C gate that opens seawater to allow the water to enter the dam.

상기의 수문들의 개폐는 자력을 이용한 것으로, 물막이 패널과 수문에 각각 자력이 발생하는 전자석을 형성하여, 수문을 여는 경우에는 전자석의 자력을 해지하여 수압으로 인하여 수문이 개방되고, 수문을 닫는 경우에는 물막이 패널과 수문에 자력을 형성하여, 자력으로 인하여 수문이 물막이 패널과 밀착되도록 한 것이다.The opening and closing of the gates by using the magnetic force, the electromagnet that generates magnetic force in the water barrier panel and the gate, respectively, and when opening the gate releases the magnetic force of the electromagnet to open the gate due to water pressure, when the gate is closed Magnetic force is formed in the water barrier panel and the water gate so that the water gate is in close contact with the water barrier panel by the magnetic force.

본 발명에서 물막이 댐 내부로 유입되거나 유출되는 해수의 흐름에 반응하여 회전하는 수차를 형성한 발전설비를 설명하면 다음과 같다.In the present invention, a power generation facility in which a water film is formed to rotate in response to a flow of seawater flowing into or out of a dam is described as follows.

수문에 각각 설치한 수차에는 해수의 흐름으로 회전할 때 발생하는 회전력을 증속기를 통하여 회전 속도를 증속한 상태에서, 동력변환을 통하여 회전력을 발전기를 통하여 발전하는 것이다.In the aberrations installed in the hydrologic gate, the rotational force generated when rotating in the flow of seawater is increased by the speed increaser through the speed increaser.

본 발명에서 수문에 결합하는 수차는, 수평 또는 수직방향으로 설비되는 것으로, 해수의 흐름 속도와 량에 따라 필요한 수차의 형태를 설정하여 설비하는 것이다.In the present invention, the aberration coupled to the hydrologic is installed in the horizontal or vertical direction, and is set up to set the type of aberration necessary according to the flow rate and amount of seawater.

본 발명의 사용을 설명하면 다음과 같다.The use of the present invention is described as follows.

해수의 조류력을 이용한 발전은, 밀물 때에는 A수문이 닫히고 B수문이 개방되어 수차가 조류의 힘으로 인해 회전하면서 발전을 하게 되고, 썰물 때에는 B수문이 닫히고 A수문을 개방하여, 조류의 힘으로 수차를 회전하여 발전하는 것이다.The power generation using the tidal power of seawater is developed by the closing of the A gate and the opening of the B gate at high tide and the rotation of the aberration due to the tidal force, and the closing of the B gate and the opening of the A gate at low tide. It is developed by rotating aberrations.

상기의 동작을 위해서 설비되는 수문의 구성을 살펴보면, 밀물 때 사용하는 A수문은 바다 쪽 수위보다 약 1~2m 높은 곳에 좁게 설치되므로, 좁은 B수문을 통해 유입되는 해수는 빠른 속도와 힘을 가지고 움직이게 때문에 수차를 회전시키는데 충분한 동력원으로 사용되는 것이다.Looking at the configuration of the hydrological gates installed for the above operation, since the A hydrological gates used at high tide is installed narrowly about 1 to 2 meters above the sea level, the seawater flowing through the narrow B hydrological gates moves with high speed and power. Therefore, it is used as a sufficient power source to rotate the aberration.

본 발명에서 썰물 때에는 B수문을 통과하여 물막이 댐 내부로 유입된 해수의 량과 만조가 될 때에 열어둔 C수문을 통과하여 유입된 해수의 량으로 바다 쪽보다 육지 쪽의 해수의 높이가 1~2m 높아지므로, 육지 쪽의 많은 해수의 힘으로 A수문을 통과하며 수차를 회전하여 발전하는 것이다.In the present invention, when the ebb tide is the amount of seawater flowing through the B water gate into the dam and the amount of sea water flowing through the C water gate opened at high tide, the height of the sea water on the land side than the sea side is 1 ~ 2m As it rises, it develops by rotating the aberration through the A gate by the force of many seawaters on the land side.
