연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A self-supporting, submersible generating plant for producing electricity from ocean currents, consisting of two counter-rotating, rear-facing turbines with a plurality of rotor blades extending radially outward from two separate horizontal axis that convey the kinetic energy from the two side-by-side, counter-rotating turbine rotors through separate gearboxes to separate generators that are housed in two watertight nacelles that are located sufficiently far apart to provide clearance for the turbine rotors. The two generators and their gearboxes serve as ballast and are located far below a streamlined buoyancy tank that extends fore and aft above and between them. A combination of a leverage system and a pressure-controlled system adjusts the hydrodynamic lifting forces to maintain constant depths. There are systems to purge the ballast water to facilitate the recovery of both individual submersible power plants and a group of many submersible power plants.

I claim: 1. A submersible electrical power generating plant for generating electrical power from ocean current, the submersible electrical power generating plant comprising: a submersible electrical power generating structure, a streamlined, torpedo-shaped buoyancy tank, a pair of water turbine rotors, and a pair of watertight nacelles, the power generating structure comprising a superior located center of buoyancy, an inferior located center of gravity, and a center of drag, the buoyancy tank comprising a nose end, a rear end, a top side, a bottom side, a left side, a right side, a front compartment a rear compartment, a pair of airfoil-shaped hydrofoils, and a pressurizeable ballast water purging system, said pair of hydrofoils having a first hydrofoil and a second hydrofoil, said first hydrofoil being a mirror image of said second hydrofoil, said first hydrofoil fixed on said left side of said buoyancy tank projecting horizontally leftward and said second hydrofoil fixed on said right side of said buoyancy tank protecting horizontally rightward, said pair of hydrofoils located at said rear end of said buoyancy tank, said pair of hydrofoils capable of providing said submersible electrical power generating structure with more lift at high angles of attack when the leading edges of the hydrofoil is are higher than the trailing edges in relation to the flow of water, the buoyancy tank being located above and between the pair of water turbine rotors, the water turbine rotors each having a water turbine axis parallel to the buoyancy tank, the pair of watertight nacelles connecting to the water turbine axes, the pair of nacelles being interconnected via center-connecting, means, the center-connecting means having an upside, a downside and a center point, the center point being placed below and slightly forward of the center of drag, the center-connecting means being mounted to the bottom side of the buoyancy tank, the pressurizeable ballast water purging system and a first depth-control system and a second depth control system, the first depth-control system being controlled by hydrostatic pressures and housed within the buoyancy tank for transferring ballast water between the front and rear compartments, the transferable ballast water for selectively raising or lowering the front and rear ends, the second depth control system comprising an attaching device located at said center point of said center connecting means, said attaching device being adjustable up and down vertically by a device to adjust the leveraged drag forces to change the angle of attack of said pair of the rigidly attached hydrofoils to balance the hydrodynamic lifting forces to changes in the downward vector forcer caused by changes in drag force acting through a downward angled anchor line, said first and second depth control systems to combine the accuracy of said first depth control system with the speed and reliability of said second depth control systems, the pressurizeable ballast water purging system for controllably purging the front and rear compartments of ballast water for raising the power generating plant to a water surface. 2. The power generating plant of claim 1 wherein the pressurized ballast water purging system comprises a plurality of drain holes, a plurality of drain pipes, a plurality of water drain valves, a plurality of special valves that allow only the passage of liquids, and a master conduit for ejecting the purging ballast water, the drain pipes extending intermediate the master conduit and the drain holes, the water drain valves and the special valves being cooperatively associated with the drain pipes for allowing ballast water to pass there through, the master conduit for directing piped ballast water downward from the nose end of the buoyancy tank during recovery to raise said nose end to increase the hydrodynamic lifting force by increasing the angle of attack of the attached airfoil-shaped hydrofoils. 3. The power generating plant of claim 2 wherein the front and rear compartments and any intermediate compartments are separated by bulkheads that have superior located vent holes, all of said compartments being capable of being pressurized equally via the superior located vent holes and pressurizing means, the pressurized compartments for purging ballast water from the buoyancy tank. 4. The power generating plant of claim 1 comprising a power collection and transmission structure, the power collection and transmission structure being connected to the power generating structure for collecting and transmitting electrical current generated by the power generating structure. 5. The power generating plant of claim 1 wherein said first depth control system comprises a pressure switch and a dual-direction pipe system, the dual direction pipe system comprising a first direction pipe assembly and a second direction pipe assembly, the first direction pipe assembly for transferring ballast water from the font compartment to the rear compartment, the second direction pipe assembly for transferring ballast water from the rear compartment to the front compartment. 6. The power generating plant of claim 5 wherein the first direction pipe assembly comprises a first set of pipes, a first pump, and a first special check valve that will not allow water to flow in one direction and will not allow water to flow in the opposite direction when below a minimum pressure, the second direction pipe assembly comprising a second set of pipes, a second pump, and a second special check valve that will not allow water to flow in one direct and will not allow water to flow in the opposite direction when below a minimum pressure, the first and second special check valves for preventing ballast water siphoning, the first and second pumps being controlled by the pressure switch, the pressure switch being able to be actuated by hydrostatic water pressure, the first pump being operable for transferring ballast water from the front compartment to the rear compartment when the hydrostatic pressure goes above a first preset limit, the second pump being operable for transferring ballast water from the rear compartment to the front compartment when the hydrostatic pressures goes below a second preset limit.
