Wave power generation as a source, ocean temperature differential generation using the temperature difference according to the depth of the current, tidal power generation using the difference between tides, and current generation using the current as the energy source due to the difference of tidal currents and the topography.
그 중 화력발전 및 수력발전은 막대한 건설비가 요구되며, 화력발전은 화석에너지에 따른 공해문제를 발생하며, 수력발전은 댐 건설후 광범위한 지역의 수몰에 따른 생태계의 변화는 물론 심한 경우에는 해당지역의 기후까지도 변화시키는 2차적인 환경문제가 제기되고 있는 실정이다.또한 풍력발전 및 태양열발전은 기상상태의 영향에 지배되므로, 바람이 없는 경우 및 태양복사에너지가 차단되는 경우에는 발전시스템을 가동시킬 수 없다.Among them, thermal power generation and hydropower generation require enormous construction costs, and thermal power generation causes pollution problems due to fossil energy. Secondary environmental problems that change the climate are also being raised. In addition, wind and solar power are governed by the effects of weather conditions, so the power generation system can be operated in the absence of wind and when solar radiation is blocked. none.
원자력발전은 방사선 누출을 차단하기 위해 시설 투자에 막대한 비용이 소비되며, 또한 폐기물 처리에 막대한 비용을 소비해야 하는 등의 여러 제약이 따르는 문제가 있으며, 한 번의 사고라도 발생되면 심각한 환경파괴를 초래하는 위험이 항상 존재한다.Nuclear power generation is subject to enormous costs in investing in facilities to block radiation leaks and incurring enormous costs in waste disposal, and in the event of a single accident, serious environmental damage can occur. There is always a risk.
파력발전 및 해양온도차발전은 입지조건에 적당한 지역이 상당히 제한적임에 따라 보편적으로 적용되기가 어려운 문제가 있는 실정이다.Wave power generation and ocean temperature differential generation have a problem that it is difficult to apply universally because the area suitable for the location conditions is quite limited.
또한, 조력발전은 조석현상에 의한 조수 간만의 차이를 이용하는 것으로, 조석현상은 달과 태양의 인력에 의해 지배적으로 발생되며, 지구가 공전할 때 생기는 원심력의 차이도 영향을 미친다. 조력발전은 조수 간만의 차이가 발생하는 지역의 하구나 만을 댐으로 막아 해수를 가두고 수차발전기를 설치하여 수위차를 이용하여 발전하는 방식이다.

The tidal power generation can predict the change of tides when the place of power generation is determined, and there is an advantageous aspect of clean energy, but it devastates tidal flats and requires a huge area, which has a huge impact on the marine environment, and can actually be used. The minimum effective drop for energy conversion is about 5 m, and the system must be installed in a location where at least about 5 m of tide occurs. To achieve greater efficiency, the difference between tidal points on different sides of the dam It must be large.
건설된 댐을 기준으로 양측간의 해수의 위치에너지에 의한 수압차만을 이용하여 발전하는 조력발전 시스템과 해류발전 시스템과는 차이가 있는데, 이러한 차이점 중 가장 큰 점은 해류발전을 하는 경우에는 해류의 운동에너지를 적극적으로 이용한다는 측면에 있다. 그러므로 해류발전은 조수 간만의 차이가 큰 지역 뿐만 아니라 해류 속도가 빠른 지역도 적당한 입지조건에 해당되며, 조력발전을 하기 위해 요구되는 5 m 이상의 조수차 보다 작아도 실질적으로 발전할 수 있다.There is a difference between tidal power generation system and current generation system that generate power by using only the pressure difference by the potential energy of seawater between the two sides with respect to the constructed dam. The biggest difference among these is the current movement It is in terms of actively using energy. Therefore, current generation is not only the region where the tidal difference is big, but also the region where the ocean current is high, and it is suitable location condition.
또한 해류발전은 날씨의 변화와 상관없이 계속적인 발전이 가능한 것과 동시에 오염이 없는 청정 에너지원을 이용한다는 측면에서 다른 발전시스템 보다 유리하다.In addition, current generation is advantageous over other power generation systems in that it uses a clean energy source that is free of pollution while continuing to generate power regardless of weather changes.
해류발전 시스템은 방파제에 터널을 형성하여 터널 내부의 발전기 모듈로부터 발전하는 방파제 내부 설치식 해류발전 시스템과, 해저면에 고정되는 지지물에 부착되는 해저면 고정식 해류발전 시스템, 및 해수면에 부유하는 부유체에 부착되는 부유식 해류발전 시스템 등이 있다.The current generation system includes an internal current generation system installed inside the breakwater, which is formed from a generator module inside the tunnel by forming a tunnel in the breakwater, a fixed bottom ocean current generation system attached to a support fixed to the bottom, and a floating body floating on the sea surface. Floating current generation system attached to the.
하지만, 이러한 기존의 해(조)류의 운동에너지를 이용하여 발전하는 해(조)류 발전장치는 과다한 부대시설과 구조물 등 비교적 유속이 빠른 장소에서만 설치가 가능한 것으로 설치 장소의 제약이 따르게 된다. However, the algae generators, which are generated using the existing kinetic energy of the algae, can be installed only at relatively high speed places such as excessive auxiliary facilities and structures, and the installation site is restricted.
또한, 빠른 속도로 흐르는 해(조)류의 운동에너지를 회전 운동으로 변환시키는 블레이드와, 블레이드의 회전축에 연결되어 전기를 발생시키는 발전기 조립체로만 구성되어 있어 발전량이 매우 제한적이며, 발전 효율이 낮아 경제성에 문제가 많았다.In addition, it consists only of a blade for converting the kinetic energy of the sea flow flowing into the rotational motion and a generator assembly connected to the rotating shaft of the blade to generate electricity, so the amount of power generation is very limited, economical efficiency is low There were a lot of problems.
그리고 기존의 해(조)류 발전장치는 해저 면에 고정되어 있어 부식으로 인한 부품의 교환과, 프로펠러에 각종 부유 물질과 해양 오염 물질로 인해 고장이 자주 발생하게 된다. 해류 또는 조류를 이용하는 발전장치는 일반적으로 해(조)류의 흐름이 비교적 센 곳에 설치되기 때문에 잠수부나 원격조정 장치를 투입하여 수중에서 조류 발전장치를 수리하기란 몹시 어려울 뿐만 아니라 인양하는데 많은 시간과 장비가 투입이 되어 불필요한 낭비요인 발생하여 왔다.In addition, the existing algae generators are fixed to the bottom of the sea, so that the failure of parts due to corrosion and the propellers due to various floating materials and marine pollutants frequently occurs. Since current generators using currents or tidal currents are generally installed in relatively strong sea currents, it is not only difficult to repair divers or remote control of tidal currents underwater, but it also takes a lot of time and effort to lift them. Equipment has been put into use, causing unnecessary waste.

Figure 4 is a schematic diagram showing the current concentration concentration portion of the power generation apparatus using the current or current according to the present invention, Figure 5 is a front view showing the current concentration concentration portion and the power generation portion of the power generation apparatus using another current or current in the present invention. As shown in the figure, the current flow concentration guide portion 3 is composed of an inlet 31, an outlet 33 and the side portion 32 to guide the current to the power generation unit (4). The inlet 31 is composed of a horizontal frame 36 and a vertical frame 37 where the current flows. The horizontal frame 36 is provided in parallel with each other in a bar shape. The vertical frame 37 is provided with a rope to support the horizontal frame 36.

The side portion 32 guides the incoming seawater to the outlet 33. In addition, when the cross-sectional area of the inlet 31 is provided with a stretchable material, the seawater can be stably guided toward the outlet 33 by being stretched accordingly. The outlet 33 supplies the inflowing seawater to the power generation unit 4. Therefore, as a whole, the current concentration induction part 3 may have a shape such as a cone, a square pyramid, and a funnel.
도 6은 본 발명에 따른 해류 또는 조류를 이용하는 발전장치의 발전부를 나타낸 개략도이다. 도면에 도시된 바와 같이, 발전부(4)는 해류집중유도부(3)의 유출구(33)와 연결되어 있다. 즉, 해류집중유도부(3)로 부터 공급되는 해수에 의해 발전부(4)에서 발전이 된다. 발전부(4)는 발전프레임(41)과 발전프레임(41)에 설치되어 해수에 의해 회전하는 블레이드(42)와, 발전프레임(41)에 마련되어 발전부(4)을 수중에서 안정적으로 위치하게 하는 부력발생부(44)로 구성된다. 발전프레임(41)은 원형으로 마련되며, 발전프레임(41)의 내부에 블레이드(42)가 설치된다.6 is a schematic view showing a power generation unit of the power generation apparatus using the current or current according to the present invention. As shown in the figure, the power generation unit 4 is connected to the outlet 33 of the current concentration concentration guide (3). In other words, power is generated in the power generation unit 4 by seawater supplied from the current concentration concentration guide unit 3. The power generation unit 4 is installed on the power generation frame 41 and the power generation frame 41 and rotated by the sea water 42 and the power generation frame 41 so as to stably position the power generation unit 4 in the water. The buoyancy generator 44 is composed of. The power generation frame 41 is provided in a circular shape, and a blade 42 is installed inside the power generation frame 41.

지지부(5)는 로프로 마련된다. 지지부(5)는 앵커부(1)와 해류집중유도부(3), 해류집중유도부(3)와 해상부유부(2), 해상부유부(2)와 앵커부(1) 각각을 상호 연결해준다. 한편 지지부는(4) 제1길이조절모터(미도시)와 연결되어 있어 제1길이조절모터(미도시)의 작동에 의해 앵커부(1), 해류집중유도부(3), 해상부유부(2) 각각의 간격을 조절할 수 있게 되어 상황에 따라 해류집중유도부(3)의 위치를 조정할 수 있게 된다. The support part 5 is provided with a rope. The support part 5 connects each of the anchor part 1 and the current concentration inducing part 3, the current concentration induction part 3 and the marine part floating part 2, the marine part floating part 2 and the anchor part 1, respectively. On the other hand, the support portion (4) is connected to the first length control motor (not shown), the operation of the first length adjustment motor (not shown) by the anchor portion (1), current concentration induction portion (3), offshore floating portion (2) Each interval can be adjusted so that the position of the current concentration induction part 3 can be adjusted according to the situation.
제1길이조절모터 및 제2길이조절모터는 해상부유부(1)에 설치된다. 상술한 바와 같이 제1길이조절모터는 지지부(5)의 길이를, 제2길이조절모터는 해류집중유도부(3)의 세로프레임(37)인 로프의 길이를 각각 조절하게 된다. 즉, 각각의 로프를 감거나 풀게 됨으로써 로프의 길이를 조절하게 된다. The first length control motor and the second length control motor are installed in the sea floating part (1). As described above, the first length control motor adjusts the length of the support part 5, and the second length control motor adjusts the length of the rope, which is the vertical frame 37 of the current concentration concentration guide part 3, respectively. That is, the length of the rope is adjusted by winding or unwinding each rope.
다음으로 본 발명에 따른 해류 또는 조류를 이용하는 발전장치의 작동에 설명한다. 본 발명에 있어서의 이론적 근거는 유체역학의 기반인 베르누이의 정리로서, 유체는 좁은 통로를 흐를 때 속력이 증가하고 넓은 통로를 흐를 때 속력이 감소한다. 즉, 한쪽은 좁고 한쪽은 넓은 출입구가 연결된 관에 일정한 압력의 유체가 흐를 때, 임의의 한 지점에서 일정한 시간 동안 흘러간 유량은 어느 곳이나 일정하다는 원리를 이용한 것이다. Next will be described the operation of the power generator using the current or current according to the present invention. The theoretical basis in the present invention is Bernoulli's theorem, which is the basis of hydrodynamics, in which the fluid increases in velocity through narrow passages and decreases in velocity through wide passages. In other words, when a fluid of constant pressure flows through a pipe connected to a narrow one side and a wide one side, the flow rate that flows for a certain time at any one point is constant.
앵커부(1) 및 해상부유부(2)에 의해 지지되는 해류집중유도부(3)는 유입구(31)의 단면적이 유출구(33)의 단면적보다 크기 때문에 유입되는 해수의 속도가 해류집중유도부(3)에서 빨라지게 된다. 따라서, 빨라진 유속에 의해 발전부(4)의 블레이드(42)가 회전할 수 있게 된다. 따라서, 유속이 빠르지 않은 지역에서도 발전이 가능해진다. The current concentration inducing portion 3 supported by the anchor portion 1 and the marine floating portion 2 has a cross-sectional area of the inlet 31 greater than that of the outlet 33 so that the velocity of the incoming seawater is the current concentration inducing portion 3. Faster). Therefore, the blade 42 of the power generation unit 4 can rotate due to the faster flow rate. Therefore, it is possible to generate power even in a region where the flow velocity is not high.
한편, 해류집중유도부(3)의 위치는 지지부(5)인 로프의 길이에 따라 수중에서 위치를 변경할 수 있게 된다. 즉, 제1길이조절모터가 작동하여 로프(5)의 길이를 조절하게 되면 로프(5)에 의해 상호 연결되어 있는 해류집중유도부(3)의 위치가 변경될 수 있다. 즉, 수심에 따라 유속이 서로 다르기 때문에 충분한 유속을 가진 수심으로 로프(5)의 길이를 조절함으로써 최적의 위치에 해류집중유도부(3)가 위치할 수 있게 된다. On the other hand, the position of the current concentration induction portion 3 is able to change the position in the water according to the length of the rope that is the support portion (5). That is, when the first length control motor is operated to adjust the length of the rope 5, the position of the current concentration induction part 3 connected to each other by the rope 5 may be changed. That is, since the flow velocity is different from each other depending on the depth of the water flow concentration guide portion 3 can be located in the optimum position by adjusting the length of the rope (5) to a depth having a sufficient flow rate.
또한, 해류집중유도부(3)의 유입구(31)의 단면적은 세로프레임(37)의 길이에 따라 변경이 가능하게 된다. 즉, 가로프레임(36)을 상호 지지하고 있는 로프(37)의 길이를 제2길이조절모터를 이용하여 조절함으로써 한쌍의 가로프레임(36) 사이의 간격이 조절됨으로써 유입구(31)의 단면적이 조절될 수 있다. 유속이 매우 빠른 경우에는 유입구(31)의 단면적을 작게 형성하여 최적의 발전효율을 꾀할 수 있고, 유속이 다소 느린 경우에는 유입구(31)의 단면적을 크게 함으로써 유출구(33)에서 충분한 유속을 낼 수 있도록 조절할 수 있게 된다.이에 따라, 항상 안정적으로 블레이드(42)를 회전시킴으로써 발전효율을 향상시킬 수 있게 된다. In addition, the cross-sectional area of the inlet 31 of the current concentration concentration guide 3 can be changed according to the length of the vertical frame 37. That is, by adjusting the length of the rope 37 supporting the horizontal frame 36 by using the second length adjusting motor, the distance between the pair of horizontal frame 36 is adjusted to adjust the cross-sectional area of the inlet 31. Can be. If the flow rate is very fast, the cross-sectional area of the inlet 31 can be made small so as to achieve an optimal power generation efficiency. If the flow rate is slightly slow, a sufficient flow rate can be obtained from the outlet 33 by increasing the cross-sectional area of the inlet 31. Accordingly, the power generation efficiency can be improved by rotating the blade 42 stably at all times.
