Abstract:
The invention discloses a portable hydroelectric apparatus which converts the kinetic energy of water caused by gravity into electrical energy. This conversion is accomplished without the presence of a river or stream. A new type of buoyancy motor is disclosed which is formed as a U-tube erected vertically. One leg and the curved portion at the bottom are filled with a series of separate air-filled tanks. The other leg is filled with water, with a suitable seal at the bottom of the leg through which are made to jut 11/2 tanks so the seal prevents water from leaking downward into the air space of the curved portion of the U-tube. Suitable means prevent the water column in the one leg from pushing the series of tanks out of the U-tube. The leading as well as the succeeding tanks behind it are made buoyant in sequence. In rising through the water-filled leg of the U-tube water is pushed through a nozzle which is made to operate hydroelectric devices. Provision is made to recycle both the water and air-filled tanks.
DETAILED DESCRIPTION OF THE PREFERRED MODE
Turning to FIG. 2 we see a hollow U-tube 1 with its curved portion down and with one leg longer than the other. The U-tube 1 may be attached to the side of a building or placed underground or in some other convenient location. This U-tube is made with vertical legs and is shown divided into zones A, B and C. Within the U-tube and affixed to its walls are ball bearings 2 which serve as guides to a series of air-filled tanks 4a-n. Conveyor belts 24 in zone B also serves as a tank 4 guide. Parallel to the longer leg of U-tube 1 is another,water-filled tube 3 with interconnecting pipes 5a,b. The leading tank 4a and part of the tank just below it 4b are above a rubber seal 6. Above this seal 6 the longer leg is filled with water. Below seal 6 and also including the curved portion and shorter leg of U-tube 1 is air around the series of tanks 4. Lids 28a,b are connected to the top of zone C by hinges 17a,b. Rubber seat attached to lids 30 to prevent leakage. Pipe 7 is for the passage of water from the top of zone C through a nozzle to operate turbine wheel 8 which is located over tube 3. Shaft 9 connects D.C. generator 10 to turbine wheel 8. Ball bearing lined chute 11 connects the two tops of the legs of U-tube 1. Brake shoe 35 is located to press on therouter surface of tank 4a so as to halt its possible motion.
