Abstract
The disclosed floating power plant is an ocean (10) placed flotation cylinder shaft (1) having a turbine and inlet cones section (2) affixed so as to let a fluid column (3) move up and down through the turbine (2). The fluid column (3) is forcefully driven through the turbine (2) by two piston sections (4 & 5) connected by piston rods (6). The piston sections (4 & 5) are kept near stationary by the pressure plate (7) and alternately compresses the fluid (3) against either side of the turbine (2) as the floatation cylinder shaft (1) moves up and down with the changing ocean wave surface (8) through buoyancy of the flotation chambers (11). Suspension (9) helps pull the turbine (2) in the downward direction. During high-pressure compression fluid (3) is bled off to a high-pressure hydraulic system (16). Low-pressure fluid is returned again during the low-pressure cycle (17). The upper piston section (4) is open to the vent (12) and can be vented to the open air. Rotation of the turbine (2) is transferred through the axle (13) to the gearbox and generator room (14). The power plant is kept in position by hydraulic control jets (15).
Claims
AMENDED CLAIMS
[(received by the International Bureau on 01 July 2003 (01.07.03); original claims 1-11 replaced by new claims 1-12]
1 A floating power plant comprising a flotation cylinder shaft with a turbine affixed in which two piston sections, connected on either side of said turbine, can be kept near stationary, allowing up and down movement in the flotation shaft to force alternating fluid flows through the turbine.
2 A floating power plant according to claim 1 wherein the piston arrangement is kept dampened in near stationary position by a suspended pressure plate or by a large buoyancy incorporated in the piston arrangement that may be combined with or without a taut mooring of said piston arrangement.
3 A floating power plant according to any one of claims 1 and 2 wherein the high pressure spikes occurring in the compression zones between the turbine and the piston arrangement are bled off to a hydraulic pressure system.
4. A floating power plant according to any one of claims 1-3 wherein the turbine is placed externally and replaced by a fixed or moving barrier between the piston chambers.
5 A floating power plant according to any one of claims 1-4 wherein the suspended pressure plate is of impervious construction.
6 A floating power plant according to any one of claims 1-4 wherein the suspended pressure plate is of pervious construction.
7 A floating power plant according to any one of claims 1-6 wherein the suspended pressure plate incorporates turbines producing high fluid pressure or turbines producing high axial inertia.
8 A floating power plant according to any one of claims 1-7 wherein the commissioned position is maintained by activating hydraulic jets as per correction requirement determined by readings of the GPS, Global Positioning System.
9 A floating power plant according to any one of claims 1-8 wherein the vertical axis is maintained by activating hydraulic jets as per correction requirement determined by gyroscope.
10 A floating power plant according to any one of claims l-9wherein the downward movement of the flotation shaft is assisted by springs attached to the near stationary lower section.
11 A floating power plant according to any one of claims 1-10 wherein the piston and turbine interaction is exchanged for linear electromagnetic generators operating with or without reactive fields.
12 A floating power plant substantially as herein before described with reference to Fig. 1 and 2 of the accompanying drawings.
