본 발명의 조류발전장치(200)는 대략 직육면체인 몸체(202) 내부에 다수개의 프로펠러(214)가 장착된 상태로 설치된다. 몸체(202)는 정면과 후면이 개방되어 있으며, 상하, 좌우 측면은 닫힌 상태가 된다. 따라서 정면이나 후면을 통해 들어온 조류는 후면이나 정면을 통해서만 나가게 된다.The tidal current generator 200 of the present invention is installed in a state where a plurality of propellers 214 are mounted inside the body 202 which is a substantially rectangular parallelepiped. The body 202 is open to the front and rear, the top, bottom, left and right sides are closed. Therefore, algae coming in from the front or back will only go out through the back or front.
그리고 몸체(202)의 정면과 후면의 테두리는 내부로 들어가면서 약간 경사지게 형성되어 면적이 좁아지는 상태가 되므로, 조류가 조류발전장치(200) 내부로 들어가면서 베르누이 법칙에 의해 속도가 빨라지게 된다.And the edges of the front and rear of the body 202 is slightly inclined to enter the interior area is narrowed, so that the algae enters the tidal current generator 200, the speed is increased by Bernoulli law.
몸체(202)의 정면과 후면에는 이물질이나 어류 등의 침투를 막기 위한 안전망(204)이 설치될 수 있다. Safety nets 204 may be installed on the front and rear of the body 202 to prevent foreign substances or fish from infiltrating.
몸체(202)의 하부에는 다리 형태의 지지대(206)가 다수 설치되는데, 지지대(206)에는 슬라이드식 연장다리(208)가 설치되어 해저면의 높이나 굴곡에 따라 연장되면서 몸체(202)의 수평을 유지한다.The lower portion of the body 202 is provided with a plurality of support legs 206 in the form of legs, the support 206 is provided with a sliding extension leg 208 extends in accordance with the height or bending of the sea bottom to level the body 202 Keep it.
몸체(202)의 내부에는 가로방향과 세로방향의 프레임(210, 212)이 설치된다.Inside the body 202, the frames 210 and 212 in the horizontal and vertical directions are installed.
세로 프레임(210)은 각각의 발전장치를 구성하는 기본단위별로 제작되며, 조류발전장치(200)의 크기에 따라 발전설비를 늘이거나 줄일 수 있도록 조립 방식으로 설치된다. 이를 위해 세로 프레임(210)의 표면에 슬라이딩홈을 형성하여 인접한 세로 프레임(210)끼리 서로 맞물리면서 상하로 움직일 수 있도록 한다.The vertical frame 210 is manufactured for each basic unit constituting each power generator, and is installed in an assembly manner to increase or decrease the power generation equipment according to the size of the tidal current generator 200. To this end, sliding grooves are formed on the surface of the vertical frame 210 so that the adjacent vertical frames 210 may move up and down while being engaged with each other.
가로 프레임(212)은 몸체(202)의 형상을 유지하며, 프로펠러(214)의 회전축을 고정하는 역할을 한다. 세로 프레임(210) 사이에는 두 개 내지 네 개 정도의 가로 프레임(212)이 설치될 수 있다.The horizontal frame 212 maintains the shape of the body 202 and serves to fix the rotation axis of the propeller 214. Two to four horizontal frames 212 may be installed between the vertical frames 210.
프로펠러(214)는 정면 또는 후면을 향하도록 설치될 수 있는데, 정면과 후면에 서로 반대방향의 프로펠러(214)를 설치하여 조류의 방향이 바뀌어도 동일한 발전량을 유지할 수 있다.The propeller 214 may be installed to face the front or the rear, by installing the propeller 214 in the opposite direction on the front and rear to maintain the same amount of power generation even if the direction of the current changes.
몸체(202)의 상부는 2층으로 구성되며, 1층에는 발전기(222)와 전력선(224)이 배치되며, 2층에는 엔진(226)이 배치된다.The upper portion of the body 202 is composed of two floors, the generator 222 and the power line 224 is disposed on the first floor, the engine 226 is disposed on the second floor.
발전기(222)는 프로펠러(214)의 회전력을 이용하여 전기를 생산하며, 전력선(224)은 생산된 전력을 전력케이블(도면 미도시)을 이용하여 육지나 해상에 있는 송배전 시스템으로 전송한다.The generator 222 generates electricity by using the rotational force of the propeller 214, and the power line 224 transmits the generated power to a power distribution system on land or at sea using a power cable (not shown).
엔진(226)은 조류가 없는 상황에서도 전력의 생산이 이루어지도록 발전기(222)를 돌려주는 역할을 한다. 엔진(226)은 가솔린이나 디젤 엔진을 사용할 수도 있고, 기타 풍력에 의해 회전하는 장치를 사용할 수도 있을 것이다.The engine 226 serves to turn the generator 222 to produce power even in the absence of tidal flow. The engine 226 may use a gasoline or diesel engine, or may use a device that is rotated by other wind power.
엔진(226)에서 발생한 회전력은 기어박스(228, 232)와 구동축(230)을 통해 발전기(222)에 전달된다. 기어박스(228, 232)는 엔진(226)에서 발생한 회전력의 방향을 전환하여 전달한다.The rotational force generated in the engine 226 is transmitted to the generator 222 through the gear boxes 228 and 232 and the drive shaft 230. The gearboxes 228 and 232 change the direction of the rotational force generated by the engine 226 and transmit them.
본 발명의 조류발전장치(200)에서 회전력을 발생하는 곳은 프로펠러(214)이므로, 프로펠러(214)가 설치된 부분은 해수면 아래에 위치해야 하며, 발전기(222)와 엔진(226) 등이 설치된 상부는 해수면 위로 올라오도록 한다. 이를 위해 적절한 높이와 크기로 설계하게 될 것이다.Where the rotational force is generated in the tidal current generator 200 of the present invention is a propeller 214, the portion where the propeller 214 is installed should be located below the sea surface, the generator 222 and the engine 226, the upper portion is installed To rise above sea level. This will be designed with the appropriate height and size.

Do.
네 개의 세로 프레임(210)이 사각 기둥을 형성하고, 그 사이에 가로 프레임(212)이 설치된다. 각각의 가로 프레임(212)에는 프로펠러(214)의 회전축이 하나씩 고정되며, 상부면에는 개구부가 형성되어 구동축(218)의 말단이 노출된다.Four vertical frames 210 form square pillars, and horizontal frames 212 are installed therebetween. Rotating shafts of the propellers 214 are fixed to each horizontal frame 212 one by one, and an opening is formed in the upper surface thereof to expose the ends of the driving shaft 218.
한 쌍의 프로펠러(214)는 가운데 기어박스(216)를 중심으로 앞뒤로 설치된다. 기어박스(216)는 회전축이 전후 방향으로 놓여진 채 회전하는 프로펠러(214)의 회전력을 회전축이 상하 방향으로 놓여진 구동축(218)에 전달하여 회전하도록 한다. 이를 위해 기어박스(216)에는 웜기어나 헬리컬기어가 사용될 수 있다.The pair of propellers 214 are installed back and forth around the center gearbox 216. The gear box 216 transmits the rotational force of the propeller 214 that rotates while the rotary shaft is placed in the front-rear direction to the driving shaft 218 which is rotated in the vertical direction. To this end, the gearbox 216 may be a worm gear or a helical gear.
본 발명에서는 한 쌍의 프로펠러(214)를 3층으로 설치하여 하나의 구동축(218)을 회전시키도록 구성한다. 이를 위해 세 개의 기어박스(216)가 3층으로 설치되어 모두 여섯 개의 프로펠러(214)의 회전력을 구동축(218)에 전달한다.In the present invention, a pair of propellers 214 are installed in three layers so as to rotate one drive shaft 218. To this end, three gearboxes 216 are installed in three layers to transmit the rotational force of all six propellers 214 to the drive shaft 218.
구동축(218)의 상측 말단에는 또 다른 기어박스(220)가 설치되며, 구동축(218)의 회전력을 발전기(222)에 전달하여 전력을 생산한다.Another gear box 220 is installed at the upper end of the drive shaft 218, and transmits the rotational force of the drive shaft 218 to the generator 222 to produce power.
본 발명에서 사용하는 기어박스(216)에는 감속 또는 가속을 위한 기어장치가 추가될 수 있다.In the gearbox 216 used in the present invention, a gear device for deceleration or acceleration may be added.
발전기(222)에는 전력선(224)이 연결되어 생산된 전력을 다른 장소로 전송할 수 있다.The power line 224 may be connected to the generator 222 to transmit the generated power to another place.
그리고 아래위의 프로펠러(214) 사이의 구동축(218)에는 헬리컬터빈(234)이 설치되는데, 헬리컬터빈(234)은 구동축(218)을 회전축으로 사용하여 회전력을 추가로 발생시킨다.And a helical turbine 234 is installed on the drive shaft 218 between the lower and upper propellers 214, the helical turbine 234 generates a rotational force by using the drive shaft 218 as a rotating shaft.
헬리컬터빈(234)은 연속적으로 꼬여있는 블레이드에 의해 회전력을 발생시키는 장치로서, 프로펠러(214) 사이를 지나가는 조류에 의해 구동된다. Helical turbine 234 is a device for generating a rotational force by a blade twisting continuously, is driven by a bird passing between the propeller 214.
프로펠러(214)와 헬리컬터빈(234)에서 발생한 회전력이 함께 발전기(222)를 회전시키면서 더 큰 전력을 생산할 수 있다. 또한 헬리컬터빈(234)은 별도의 기어박스(216)를 설치하지 않아도 구동축(218)을 그대로 회전시킬 수 있는 장점이 있다.The rotational force generated by the propeller 214 and the helical turbine 234 can produce greater power while rotating the generator 222 together. In addition, the helical turbine 234 has the advantage that the drive shaft 218 can be rotated as it is without installing a separate gear box 216.
