Description

수류 및 풍력 겸용 발전장치{Water stream and wind power generation apparatus}Water stream and wind power generation apparatus

본 발명은 부유체에 설치된 수차가 수류 또는 풍력에 의하여 회전하면서 전기를 생산하도록 된 수류 및 풍력 겸용 발전장치에 관한 것이다.The present invention relates to a water current and wind power generator combined with a water wheel installed on a floating body to generate electricity while rotating by the water current or wind power.

최근 전기의 생산은 화석 연료의 고갈, 환경 오염, 지구 온난화 등의 문제로 전통적인 화력 발전에서 풍력, 수력, 조력, 태양열 등의 친환경 발전으로 그 중심이 옮겨가고 있는 추세이다.In recent years, electricity generation is shifting its focus from traditional thermal power generation to eco-friendly power generation such as wind power, hydropower, tidal power, and solar power due to problems such as depletion of fossil fuels, environmental pollution, and global warming.

그러나 풍력발전은 풍속 및 풍량의 변동폭이 커서 안정적인 발전에 어려움이 있으며 설비의 고비용과 유지보수의 어려움이라는 문제가 있고, 우리나라의 기후적 특성상 항시 일정 이상의 강도로 바람이 불어오는 지역이 극히 제한적이어서 널리 보급되기 힘든 문제가 있다.However, wind power generation has difficulties in stable power generation due to large fluctuations in wind speed and volume, high cost of equipment and difficulty in maintenance and repair. There are problems that are difficult to spread.

이에 반해 조력발전은 바다의 물살이 빠른 곳에 수차발전기를 설치해 조류의 흐름으로부터 전기 에너지를 생산하므로 어느 정도 예측이 가능하다는 점에서 장점이 있다.On the other hand, tidal power generation has an advantage in that it can be predicted to some extent because it generates electric energy from the flow of tidal currents by installing a water turbine generator in a place where the current of the sea is fast.

그러나, 우리나라의 연안의 조류는 풍부하기는 하나 10kn 전후의 강한 조류의 개체수가 적고 평균 3kn 전후의 비교적 낮은 유속의 조류가 대부분이어서, 강한 조류를 요구하는 방식의 조력발전기는 실용적이지 않을 뿐만 아니라 안전한 설치를 위해서는 일정 이상의 수심이 요구되는 제약이 뒤따른다.However, although tidal currents in the coast of Korea are abundant, the number of strong tidal currents around 10kn is small and most of the tidal currents with relatively low flow rates around 3kn on average are not practical. For installation, there is a restriction that a water depth of more than a certain level is required.

이때, 좌측부유체(110)와 우측부유체(120)는 강이나 해수면에 부유되며, 상기 좌측부유체(110)와 우측부유체(120)에 설치된 수평수차(141)가 수류와 접촉하면서 수류 방향으로 회전하게 된다.At this time, the left floating body 110 and the right floating body 120 are suspended in a river or sea level, and the horizontal aberration 141 installed in the left floating body 110 and the right floating body 120 is in contact with the water flow in the direction of the water flow. will rotate

상기 수평수차(141)가 회전하게 되면 제1발전기(142)가 발전을 하게 되고, 발전을 통해 생산된 전기는 배터리(160)에 충전된다. 충전된 전기는 송전케이블(200)을 통해 외부로 전송된다.When the horizontal water wheel 141 rotates, the first generator 142 generates power, and the electricity generated through the power generation is charged in the battery 160 . The charged electricity is transmitted to the outside through the power transmission cable 200 .

이와 같은 본 발명의 수류 발전장치는 구조가 단순하여 제작이 쉽고 수면위에서 발전이 이루어지므로 약한 수류와 낮은 수심에도 발전이 원활하게 이루어지므로 국내의 지형 조건에 적용하기가 매우 유리하다.The water current generator of the present invention has a simple structure, so it is easy to manufacture and power generation is performed on the water surface.

따라서, 본 발명의 수류 발전장치를 수면 위에 일정간격으로 다수 설치하게 되면, 적은 비용으로 다량의 전기를 생산할 수 있게 된다.Accordingly, when a plurality of water current generators of the present invention are installed at regular intervals on the water surface, it is possible to produce a large amount of electricity at a low cost.

도시되지는 않았으나, 본 발명의 수류 발전장치는 반드시 수류가 수평방향으로 흐르는 강이나 해수면에 설치할 필요는 없고, 수류가 상하방향인 낙차를 가진 지역에도 설치가 가능하다. 이 경우 낙하하는 물에 의해 수평발전유닛(140)의 수평수차(141)가 회전하면서 발전이 이루어지게 된다.Although not shown, the water current generator of the present invention does not necessarily need to be installed in a river or sea level through which the water flow flows in the horizontal direction, and can be installed even in an area where the water flow has a vertical drop. In this case, power is generated while the horizontal water wheel 141 of the horizontal power generation unit 140 is rotated by the falling water.

한편, 수류가 약해지면서 상대적으로 풍력이 강해지면 상기 제어부가 센서부를 통해 이를 감지하고 승강유닛(170)의 동작을 제어하여 수직발전유닛(150)을 일정높이로 상승시킨다. 이에 따라, 수직발전유닛(150)은 수면위로 부상하게 되며 풍력발전모드로 전환된다.On the other hand, when the wind power is relatively strong as the water flow weakens, the control unit detects this through the sensor unit and controls the operation of the lifting unit 170 to raise the vertical power generation unit 150 to a predetermined height. Accordingly, the vertical power generation unit 150 floats above the water surface and is switched to the wind power generation mode.

이와 같이 수직발전유닛(150)이 풍력발전모드로 전환되면 수직수차(151)(150)가 바람에 의해 회전하면서 풍력발전이 이루어지게 된다.As such, when the vertical power generation unit 150 is switched to the wind power generation mode, the vertical water turbines 151 and 150 rotate by the wind to generate wind power.

따라서, 본 발명은 풍속과 수류와 유입속도에 따라 제어부가 예상발전량을 산출하고, 이에 따라 수직발전유닛(150)이 승강하면서 유리한 발전모드로 자동 전환되므로 풍속과 수류의 유입속도가 약할 경우에도 안정적인 발전을 수행할 수 있게 된다.Therefore, in the present invention, the control unit calculates the expected power generation amount according to the wind speed, the water flow, and the inflow speed, and accordingly, the vertical power generation unit 150 automatically switches to an advantageous power generation mode while ascending and descending. development can be carried out.

한편, 본 발명은 수심이 얕은 경우에는 상기 수직발전유닛(150)을 상승시켜 풍력발전모드로 전환시키고, 수심이 깊은 경우에는 상기 수평발전유닛(140)을 하강시켜 수류발전모드로 전환시킴으로써 수심에 따른 효율적인 운용도 가능하다.On the other hand, in the present invention, when the water depth is shallow, the vertical power generation unit 150 is raised to switch to the wind power generation mode, and when the water depth is deep, the horizontal power generation unit 140 is lowered to convert the water current generation mode to the water depth. Efficient operation is also possible.

도 3은 본 발명의 다른 실시예에 따른 수류 및 풍력 겸용 발전장치의 평면도이고, 도 4는 도 3의 Ⅳ-Ⅳ에 따른 사용상태 단면도로서, 도시된 바와 같이, 상기 수평발전유닛(140)은 승강부재(172)를 통해 승강가능하게 설치되어 상승시 수류발전모드에서 풍력발전모드로 전환되도록 구성될 수 있다.3 is a plan view of a combined water flow and wind power generation device according to another embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along IV-IV of FIG. 3, as shown, the horizontal power generation unit 140 is It is installed so as to be elevating through the elevating member 172 and may be configured to be switched from the water current generation mode to the wind power generation mode when ascending.

이 경우, 상기 승강유닛(170)은 상기 수평발전유닛(140)의 제1발전기(142)와 연결된 제2연결바(174)를 구비한다.In this case, the lifting unit 170 includes a second connecting bar 174 connected to the first generator 142 of the horizontal power generation unit 140 .

또한, 상기 제1발전기(142)의 측벽에는 제1전기접속단자(144)가 형성되고, 상기 좌측부유체(110)와 우측부유체(120)에는 상기 제1발전기(142)의 승강을 안내하는 수직안내면(114)이 형성되며, 상기 수직안내면(114)에는 상승한 제1발전기(142)의 제1전기접속단자(144)와 접촉하여 제1발전기(142)와 배터리(160)를 전기적으로 연결시켜 주는 제2전기접속단자(115)가 형성될 수 있다.In addition, a first electrical connection terminal 144 is formed on the sidewall of the first generator 142, and the left floating body 110 and the right floating body 120 are provided to guide the elevation of the first generator 142. A vertical guide surface 114 is formed, and the vertical guide surface 114 is in contact with the first electrical connection terminal 144 of the raised first generator 142 to electrically connect the first generator 142 and the battery 160 A second electrical connection terminal 115 may be formed.

이 경우, 상기 수평발전유닛(140)이 상승하더라도 상기 제1전기접속단자(144)와 제2접기접속단자를 통해 상기 제1발전기(142)는 안정적으로 배터리(160)와 전기적으로 접속된 상태를 유지할 수 있게 된다.In this case, even when the horizontal power generation unit 140 rises, the first generator 142 is stably electrically connected to the battery 160 through the first electrical connection terminal 144 and the second folding connection terminal. be able to maintain

따라서, 상기 제어부가 센서부를 통해 풍속과 수류의 유입속도를 감지하다가 풍력이 약해지면서 상대적으로 수류가 강해지면 승강유닛(170)의 동작을 제어하여 수평발전유닛(140)을 하강시키게 되며, 수평발전유닛(140)이 하강함에 따라 상기 수평수차(141)는 하부가 수면에 잠기면서 수류발전모드 상태가 된다. 아울러, 수류가 약해지면서 상대적으로 풍력이 강해지면 상기 승강유닛(170)이 수평발전유닛(140)을 상승시키게 되고 상기 수평수차(141)가 수면 위로 부상하면서 풍력발전모드로 전환된다.Therefore, when the control unit detects the wind speed and the inflow speed of the water flow through the sensor unit and the wind power weakens and the water flow becomes relatively strong, the control unit 170 controls the operation of the lifting unit 170 to lower the horizontal power generation unit 140, and horizontal power generation As the unit 140 descends, the horizontal water wheel 141 enters the water current generation mode while the lower part is submerged in the water surface. In addition, when the wind power is relatively strong as the water flow is weakened, the lifting unit 170 raises the horizontal power generation unit 140 , and the horizontal water wheel 141 floats above the water surface and is switched to the wind power generation mode.

이때, 상기 제1발전기(142)는 수직안내면(114)을 따라 유동됨 없이 정확한 위치로 상승하게 되며, 제1발전기(142)의 상승이 완료되면 제1전기접속단자(144)와 제2전기접속단자(115)의 접속이 이루어지면서 제1발전기(142)가 상승한 상태에서도 상기 제1발전기(142)와 배터리(160)의 접속은 원활하게 이루어지게 된다.At this time, the first generator 142 rises to the correct position without flowing along the vertical guide surface 114, and when the rise of the first generator 142 is completed, the first electrical connection terminal 144 and the second electricity As the connection terminal 115 is connected, even when the first generator 142 is raised, the first generator 142 and the battery 160 are smoothly connected.
