Autodesk Fusion 360 About Joints - YouTube Although there will be some changes in the current’s velocity, caused by the moon’s tidal effects and the steadiness of the trade winds, the only renewable energy source that would have higher capacity factors than those of well-placed turbines in the Gulf Stream would be the conventional hydroelectric power plants that have sufficient water in their reservoirs. Because the Gulf Stream’s current is relatively consistent, well-placed turbines powered by that current should generate usable electricity virtually one hundred percent of the time.

There the current has reached a speed of as much as 7.75 mph in its narrow central axis. In addition to producing the Coriolis Effect that produces the oceans’ gyres, another consequence of the earth’s eastward rotation is that the center of each of those gyres is offset toward the western edge of the ocean basin that confines it. Because the volume of water flowing toward the poles along the narrower western sides of the gyres is the same as that circulating back toward the Equator down the much broader eastern expanses, the constricted western currents are forced to flow much faster than their eastern counterparts. Among the patented inventions to generate electricity from ocean currents, there are tethered devices that rely on hydrofoils and/or ballast tanks to provide lifting forces to keep the devices at the desired depths. The third connecting means 12, 13, 14, 15, 25 and 26 are long enough to ensure the submersible electrical power generating structure 1 having the center of buoyancy 221 located above the center of gravity 222. The first nacelle 17 is securely mounted to the bottom side 232 of the streamlined torpedo-shaped buoyancy tank 11 through a first connecting means 13 and 14. The second nacelle 27 is securely mounted to the bottom side 232 of the streamlined torpedo-shaped buoyancy tank 1 1 through a second connecting means 25 and 26. The pair of watertight nacelles 17 and 27 is located sufficiently far apart to provide clearance for the pair of side-by-side counter-rotating full-bladed water turbine rotors 16 and 28. FIG.

A first gearbox 54 containing planetary and helical gears converts the low speed to high speed to drive a first high-speed shaft 55. An eddy current clutch 56 makes the connection between the first high speed shaft 55 and 57 when the RPM of the shaft are synchronized with the 60- cycle current to drive the first electrical power generator 58. The invention may be modified to produce the same amount of electricity from low current velocities by increasing the diameter of the pair of side-by-side counter-rotating full-bladed water turbine rotors 16 and 28 and by increasing the gearing in the first gearbox 54 in first watertight nacelle 17, and second gearbox (not shown) in the second watertight nacelle 27 to convert the slower shaft speed to the high shaft speed required by the generator 54. At the bottom of each of the nacelles is a float operated sump pump 59. Since the second watertight nacelle 27 is a mirror image of the first watertight nacelle 17, the second watertight nacelle 27 has a similar structure as the first watertight nacelle 17. All the first gear box 54, the second gear box, the first low-speed shaft 53, the second low-speed shaft, the first high-speed shaft 55, the second high-speed shaft, the first electrical power generator 58 and the second electrical power generator are lubricated and cooled by oil.

The submersible electrical power generating structure 1 further comprises a streamlined torpedo-shaped buoyancy tank 1 1 with a nose end 23, a rear end 24, a top side 231, a bottom side 232, a left side 233, a right side 234, and a plurality of compartments 68, 69, 77, 80 and 101. The center of gravity 222 of the submersible electrical power generating structure 1 can be changed longitudinally along line 256 by moving ballast water between the front compartment 68 and the rear compartment 69 of the streamlined torpedo-shaped buoyancy tank 11. If the submersible electric power generating plant 1 were floating freely underwater, the center of gravity 222 would be directly under the center of buoyancy 221. Dolor de espalda por gripe . Lines 257 and 258 illustrates how the movement of the center of gravity along line 256 produces forces to vertically rotate the submersible electric power generating structure 1. The streamlined torpedo-shaped buoyancy tank 11 has a vertical tail fin 20 capable of improving directional stability of the submersible electrical power generating structure 1, a pair of airfoil-shaped hydrofoils 10, a pair of side-by-side counter-rotating full-bladed water turbine rotors 16 and 28, and a pair of watertight nacelles 17 and 27. The vertical tail fin 20 can be on either the top side 231 of the submersible electrical power generating structure 1 extending upward or the bottom side 232 of the submersible electrical power generating structure 1 extending downward.

If the hydrostatic water pressure is too high because the submersible electrical power generating structure 1 is too deep, the pressure switch 259 activates the solenoid 271 to turn on pump 250 to pump the ballast water from the front compartment 68 to the rear compartment 69 to cause the front end 23 of the torpedo- shaped buoyancy tank 11 to move higher and the rear end 24 of the torpedo-shaped buoyancy tank 11 to move lower, which will increase the angle of attack of the attached airfoil-shaped hydrofoils 10 to cause the submersible electrical power generating structure 1 to move higher.

The first and second pumps are controlled by the pressure switch capable of being activated by the hydrostatic water pressures being outside of preset limits. The increasing lifting forces produced by the combination of the increasing buoyancy, the increasing hydrodynamic lift, and the equal and opposite reaction to the downward ejection of the ballast water from the front end of the torpedo- shaped buoyancy tank will lift the submersible electrical power generating structure to the surface. The Delhsen invention utilizes a computer system to balance those forces produced by the hydrofoil, buoyancy and drag to allow the device to seek that current that will allow for an even production of electric power. In the present invention, a submersible electrical power generating plant for generating electrical power, with virtually no operating costs, from the flow of ocean current has a submersible electrical power generating structure and an electrical power collection and transmission structure connected to the submersible electrical power generating structure for collecting and transmitting electrical current.
