Abstract

An ocean wave and tidal current energy conversion system includes a frame that has supports that receive cylinders or rotating portions that rotate from ocean or river currents to create hydraulic oil pressure via hydraulic cylinders. The hydraulic oil in the energy conversion system is pumped into a pressure accumulator that removes hydraulic surges and operates an electric generator. The electric generator may power an electrolysis batch system for the production of hydrogen.

Claims (41)

1 . An energy conversion system comprising:

a first frame;

a second frame rotatably coupled to the first frame, the second frame comprising:

a main frame;

a first sleeve that couples to the main frame and to the first frame via a first shaft, the first sleeve spanning the length of the first frame, wherein the first sleeve is a dive plane that is rotatably coupled to the main frame;

a second sleeve that couples to the main frame and to the first frame via a second shaft, the first sleeve spanning the length of the first frame, wherein the second sleeve is a dive plane that is rotatably coupled to the main frame;

wherein the second frame is rotatably coupled to the first frame via the first shaft and the second shaft;

one or more rotating portions comprising:

lower and upper plates,

rings positioned proximate to both the lower and upper plates,

actuator plates positioned within the rings,

gear plates positioned proximate the ring adjacent the upper plates,

blades coupled to blade brackets via blade axles,

the blade brackets being coupled to an upper and a lower end of each blade, each blade having two bearings and pins, wherein the two bearings and pins are positioned within first and second tracks created between the rings and actuator plates,

a central axle.

2 . The energy conversion system of claim 1 , wherein the first frame comprises a first rail and a second rail, each being spaced apart and coupled to a lower surface of the first frame, the first rail and the second rail are both weighted.

3 . The energy conversion system of claim 1 , further comprising a plurality of rotating supports that surround the one or more rotating portions.

4 . The energy conversion system of claim 1 , wherein an edge of the actuator plates and an edge of the rings include indents.

5 . An energy conversion system comprising:

a first frame comprising:

a plurality of panels and a plurality of supports;

a first rail and a second rail, each being coupled to a lower surface of the first frame;

a second frame rotatably coupled to the first frame, the second frame comprising:

a main frame;

a first sleeve with one or more first pipes, the first sleeve couples to the main frame and the first frame via a first shaft;

a second sleeve with one or more second pipes, the second sleeve couples to the main frame and the first frame via a second shaft;

wherein the second frame is rotatably coupled to the first frame via the first shaft and the second shaft;

one or more rotating portions each comprising:

a lower plate;

a first ring proximate to the lower plate, the first ring comprising a first ring aperture;

a second ring being placed in the first ring aperture, the first ring surrounding the second ring, wherein the second ring comprises a second ring aperture;

a first actuator plate positioned within the second ring aperture;

an upper plate;

a third ring proximate to the upper plate, the third ring comprising a third ring aperture;

a fourth ring being placed in the third ring aperture, the third ring surrounding the fourth ring, wherein the fourth ring comprises a fourth ring aperture;

a second actuator plate positioned within the fourth ring aperture;

blades positioned between the lower and upper plates, each blade comprising a first bracket with first bearings at a lower end of the blade and a second bracket with second bearings at an upper end of the blade;

first tracks positioned between the first ring and the second ring and the second ring and the first actuator plate, and second tracks positioned between the third ring and the fourth ring and the fourth ring and the second actuator plate, wherein the first and second tracks slidably receive the first bearings and the second bearings, respectively;

a first track switch rocker arm positioned in the first tracks that moves the first bracket and moves the first bearings to a different track with every rotation of the rotating portion;

a second track switch rocker arm positioned in the second tracks that moves the second bracket and moves the second bearings to a different track with every rotation of the rotating portion; and

a central axle.
