Abstract

The present invention relates to a floodgate device of a basin type tidal power plant, capable of securing drainage generation water or water generation drop. The device includes an arc floodgate opened and closed by a hydraulic device along a hydraulic floodgate trace in a pier vertically formed from a waterwheel generator or double current type waterwheel to an upper plate of a power plant or Su-wol-gu floodgate formed into a plane floodgate opened and closed by a burton along a waterwheel groove in order to use a residual space formed in the double current type waterwheel or waterwheel generator. As the height is adjusted by attaching a pair of outer doors to an upper part of the Su-wol-gu floodgate in a tidal power plant having a small gap between a water storage level and an upper plate of the power plant, a power generation drop is maintained until the power generation is finished and then as drainage generation water or water generation drop is additionally secured until high tide or ebb tide, the size of an exclusive floodgate for securing the drainage generation water or water generation drop is reduced or the device is replaced for the waterwheel generator including a sub floodgate.

Description

조지식 조력발전소의 수월구 수문장치{Floodgate apparatus for overflow control of the tidal generating station of lagoon type}BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a floodgate apparatus for overflow control of a tidal generating station of a lagoon type,

본 발명은 배수발전용수 또는 입수발전낙차를 확보하는 조지식 조력발전소의 수월구 수문장치에 관한 것으로, 좀 더 상세하게는, 수차발전기 또는 복류식 수차 상부에서 저수가능수위까지의 높이를 가진 수월구 수문을 개폐하여 발전이 종료될 때까지 발전용수의 유출을 차단하고 간조 때 또는 만조 때 입수발전낙차나 배수발전용수를 확보하는 보조수문으로 활용하는 조지식 조력발전소의 수월구 수문장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water level hydrangea generator of a coarse and tidal power plant for securing drainage water for generating electricity or water from a power generator, and more particularly, The present invention relates to a water gate hydrological apparatus of a coarse-grained tidal power plant, which is used as a supplementary water gate for securing water supply and drainage water for power generation at the time of low water or high tide,

조지식 조력발전소는 외해와 저수지 사이의 조류 통과공간이 방조제와 수차발전소로 좁혀져 있어 발전 수로가 저조면 아래에 설치되고 조류가 회전축과 평행하게 통과하는 프로펠러 또는 터빈을 가진 단류식 수차발전소는 유속이 가속되도록 조류 통과 공간이 더욱 좁혀져 있어 단시간에 배수발전용수를 만조수위까지 확보하거나 간조수위까지 배수하여 입수발전낙차를 확보하기 위해서는 발전소 방류량보다 훨씬 많은 발전용수를 확보할 수 있는 전용수문이 필요하다.The tidal power plant has a propeller or turbine in which the passage area between the outer sea and the reservoir is narrowed to a seawall and an aeration plant so that the water supply channel is installed at a low level and the algae pass parallel to the rotary shaft. In order to accelerate the flow of water, the passage of the algae is narrowed. Therefore, in order to secure drainage water to the high tide level or to drain water to the low water level in a short time, a dedicated water gate is required to secure much more water than the discharge amount.

특히 밀물 때 입수발전한 발전용수로 썰물 때 배수발전하는 복류식 조력발전소는 발전이 중단되었을 때부터 짧은 시간 동안에 다음 발전을 위한 입수발전낙차 또는 배수발전용수를 충분히 확보해야 하지만 낙차가 좁을수록 유속이 느려지므로 방조제 전체에 전용수문을 설치하지 않는 한 외해와 같은 만조 또는 간조수위까지 확보하기가 거의 불가능하다.In particular, a tidal power plant that is generating water at the time of low tide when the tidal power is generated by tidal power has to secure sufficient water for power generation or drainage for the next generation within a short period of time after the power generation is stopped. It is almost impossible to secure high tide or low water level such as off-shore unless a dedicated gates are installed in the whole seawall.

그러나 전용수문 설치비용이 발전소 건설비용보다 결코 적지 않고 발전소 통과수량만으로는 배수발전용수를 충분히 확보할 수도 없으므로, 전용수문 건설부지에 발전소를 증설하고 발전소구조물의 잉여공간을 보조수문으로 활용함으로써 전용수문 규모를 축소하거나 조력발전소로 대체하여 가동률로 발전량 조절이 가능하고 배수발전용수 또는 입수발전낙차를 만조 또는 간조수위에 가깝게 확보할 수 있다. 1개 발전 수로와 보조수로 통과수량이 전용수문 1개보다 결코 적지 않으므로 조류통과공간 확장으로 단시간에 발전용수 확보가 용이하기 때문이다.However, since the installation cost of the exclusive water gate is never less than the cost of constructing the power plant, and it is not possible to secure enough water for the generation of the drainage water only by the amount of water passing through the power plant, , It is possible to control the power generation rate by substituting the operation rate with the tidal power plant, and to secure the drainage water or the water supply / discharge power generation close to high tide or low water level. This is because it is easier to secure power generation water in a short time owing to the expansion of the passage area of the algae, since the number of passages for one generation and auxiliary water is never less than one for the exclusive gate.

발전낙차를 유지하기 위해서 단류식 조력발전소는 발전 수로 상부부터, 복류식 수차발전소는 복류식 수차 상단부터 저수가능수위까지 수위를 유지하는 차단벽 설치가 불가피하다. 프로펠러형 수차를 이용하는 단류식 조력발전소는 발전소구조물로 완전히 폐쇄할 수 있지만 복류식 수차발전소는 복류식 수차를 수직으로 설치하거나 인양할 때마다 차단벽이 분리될 수 있어야 한다.In order to maintain the power generation faults, it is inevitable to install a monolithic tidal power plant from the upper part of the power generation water channel, and a double-flow type aeration power plant to block the water level from the top of the aeration type water turbine to the water level. A monolithic tidal power plant using a propeller type aberration can be completely closed to the power plant structure, but a submerged aeration power plant should be able to separate the blocking wall each time a submerged aberration is vertically installed or lifted.

본 발명은 조지식 조력발전소의 이러한 잉여공간을 보조수문으로 활용하기 위하여 수월구 수문을 설치하는 것이다.The present invention is to install a water gate to utilize this surplus space of the cooperative knowledge tidal power plant as an auxiliary water gate.

수문(수월구 수문)은 발전 수로가 저조면보다 깊게 형성되고 수차발전기가 가로축으로 설치되는 단류식 조력발전소는 발전 수로 상부부터 발전소 상판 사이, 복류식 수차가 해저부터 간조수위 또는 평균해면까지 세로축으로 설치되고 발전기가 인양구에 설치되는 복류식 수차발전소는 복류식 수차 상단과 발전기 사이에서 저수가능수위까지 개폐될 수 있다.The monolithic tidal power plant, in which the power generation channel is formed deeper than the low power generation channel and the water turbine generator is installed in the horizontal axis, is installed between the power generation channel upper part and the power plant upper plate, and the submerged water turbine is installed from the sea floor to the low water level, And the generator is installed in the lifting section, the power can be opened and closed to the water storage level between the upper end of the aeration type aerator and the generator.

발전소 상판에는 수차와 발전기를 설치하거나 인양 및 보수하기 위한 크레인의 이동통로가 되어야 하므로 수월구 수문은 물론 수문 권양장치가 상판 위로 노출되지 않도록 해야한다. 또한 저수가능수위에서 발전소 상판 또는 발전기까지의 간격이 수문 폭보다 좁을 때는 개방된 수문의 높이를 낮출 수 있는 방안이 요구된다.The top plate of the power plant should be a moving passage of the crane for installing and repairing and repairing aberrations and generators, so that the hoistway gate as well as the hoistway hoisting device should not be exposed on the top plate. Also, when the distance from the water level to the power plant top plate or generator is narrower than the water gate width, it is required to reduce the height of the open water gate.

그것은 수월구 수문 상변에 부력을 가진 덧문이 경첩으로 부착되어 저수수위가 경첩 부착높이보다 낮아지면 젖혀져서 수면에 뜨거나 수월구 수문에 매달리고 수위가 높아지면 수압과 부력에 의해 자동으로 닫히도록 하는 것이다. It is attached to the top of the floodgate with a buoyant hinge attached to it. When the float level is lower than the height of the hinge, it is tilted so that it floats on the surface of the water or hangs on the floodgate. When the water level rises, it is automatically closed by water pressure and buoyancy .

수차발전기나 복류식 수차를 수리 또는 교체하기 위해 인양할 때 수월구 수문과 권양장치를 해체해야 하는 불편이 있으나 발전소 상판에서 작업할 수 있으므로 배수된 발전 수로를 통해 인양하는 노력보다 훨씬 유리할 것이다.
Although it is inconvenient to dismantle the water gate and lifting device when repairing or replacing a water turbine generator or a submersible water turbine, it will be more advantageous than the efforts to salvage through the drainage channel because it can work on the power plant roof.

본 발명은 조지식 조력발전소에 있어서 수차 상단부터 저수가능수위까지의 잉여공간을 배수발전용수 또는 입수발전낙차를 확보하는 보조수문으로 활용함으로써 전용수문 규모를 축소하거나 생략하고도 조력발전소와 방조제로 좁아진 조류 통과공간을 확장하여 발전량을 증대하는 것을 목적으로 한다.
The present invention utilizes the surplus space from the top of the aberration to the water-storage water level as a supplementary waterway for securing the drainage water or the water supply and discharge from the auxiliary water tidal power plant of the coarse and tidal power plant, And to increase the amount of power generation by expanding the alveolar passage space.

And the power generation is much increased.
