River-Flow Electricity Generation

A system of electricity generation wherein the river-flowing dynamics is converted into rotational dynamics and then into electricity by creating force imbalance around an axis with a mechanical system that consists of necessary mechanical elements is comprising:

• (a) vanes, cover, cover entrance fixture, and associate spring mass systems installed on the circumference of a circular wheel, being the necessary mechanical elements recited above, wherein as the river flows, the vanes at one side of said wheel face the water flow and lateral-pushing pressure builds up against the vanes while vanes at the other side of said wheel get folded down by said cover entrance fixture as the vanes enter into the cover area and the vanes are stored inside the cover in a folded configuration such that no lateral-pushing pressure builds up against these vanes, and thus said force imbalance is created and that causes said wheel to rotate,
• (b) spring mass system recited above, wherein as said vane is being folded in by a fixture at the entrance of said cover, it presses said mass and said spring toward the center of said wheel and the spring energy is stored and remains stored until said vane passes an exit hole, and as said vane is passing the exit hole at the end of the cover area, said spring releases its energy and pushes said vane upward so that said vane is forced to be opened and in a position that it faces against the river-water flow, thus lateral-pushing pressure builds up upon said vane and it pushes the vane in the direction of the river-water flow,
• (c) a clutch mechanism wherein a gear (A) gets engaged with another gear (B) when said gear (A) rotates faster than the other gear (B) and disengages when said gear (A) rotates slower than said other gear (B),
• (d) Said clutch mechanism wherein the gear tooth face angles of the gear (A) and the gear (B) are the same, and said gear (B) is not fixed but movable up and down and has a spring underneath such that as the gear (A) tooth moves in one direction such that as said two tooth faces are sliding with each other, said gear (A) tooth pushes said gear (B) tooth downward to the direction of the center of said gear (B) but not in the direction that said gear (A) moves, and thus disengagement occurs, while if said gear (A) moves in the other direction in the relative sense, then instead of sliding, said two gears (A and B) are facing each other and said gear (A) pushes said gear (B) in the direction in which said gear (A) moves, thus the gear engagement occurs,
• (e) “Water-Boxes” installed on the circumference of a circular wheel, being as the necessary mechanical elements wherein said Water-Box has an opening in the front and has a door in the rear that is hinged at the top (or bottom) and has a stopper on the other side of the hinge such that said door can be opened in one direction (so that the water can flow through) but not in the other direction so that as the river flows, Water-Boxes at the top (bottom) of said wheel get filled with water and the water pushes the Water-Boxes and said wheel in the direction of the river flow, while said Water-Boxes at the bottom (top) pass the water through front and rear openings and no lateral-pushing pressure can be generated, and thus said force imbalance between top and bottom is created and it causes said wheel to rotate,
• (f) “Water-Boxes” installed on a conveyor belt, being as the necessary mechanical elements wherein said Water-Box has an opening in the front and has a door in the rear that is hinged at the top (or bottom) and has a stopper on the other side of the hinge such that said door can be opened in one direction (so that the water can flow through) but not in the other direction so that as the river flows, Water-Boxes at the top (bottom) of said conveyor belt get filled with water and the water pushes the Water-Boxes and said conveyor belt in the direction of the river flow, while said Water-Boxes at the bottom (top) pass the water through front and rear openings and no lateral-pushing pressure can be generated, and thus said force imbalance between top and bottom is created and it causes said conveyor belt to rotate.
