NOVELTY - The working principle of hydro power generator is that pressure energy due to weight of liquid is converted into mechanical energy. The pressure head lost in converting mechanical energy is regained and reused. The converted mechanical energy can be used as a prime mover for electricity generation or any other purpose. As shown in figure. The vertical tank is filled with liquid. At the base of the tank, two pipes are vertically connected. The two pipes are equal in cross-sectional area and vertical height. The bottom end of two pipes are connected to cylinders respectively. The pipes consist of valves just above the cylinders. Cross-sectional areas of cylinders are equal to that of first pipe. The two cylinders consist of pistons that are connected to crank through connecting rods. At the top dead center of each cylinder, dead weight accumulators are connected in parallel. The pipes that connect accumulator consist of valves. The discharge pipes from accumulator are connected to pipes respectively just above the valves. The weight of each dead weight accumulator is slightly more than liquid weight in first pipe. The discharge pipes consist of valves to open and close the liquid flow. The cross-sectional area of dead weight accumulator is 4 times that of piston area. (To understand the working principle of hydro power generator, cross-sectional area at the base of accumulator is assumed as 4 times that of piston. This ratio can be varied depending on design). As the cross-sectional area of accumulator is 4 times that of piston area, force acting on piston during discharge stroke will be equal to 1/4th weight of dead weight accumulator. During working stroke, one set of valves is in open position. Remaining valves are in closed position. The liquid flows from first pipe to first cylinder. The first piston moves down with great force due to liquid weight. The crank rotates half the revolution. (Pressure energy due to liquid weight is converted into mechanical energy). At the same time, accumulator which is in charged condition discharges liquid into first pipe as the weight of accumulator is more than weight of liquid in the pipe and also second piston moves up charging dead weight accumulator. As the second piston reaches top dead center, and first piston reaches bottom dead center, one set of valves is closed and the other set of valves is opened. Now, liquid flow from the second pipe to second cylinder. The second piston moves down with great force. The crank completes one revolution. At the same time, dead weight accumulator discharges liquid into second pipe. As the weight of accumulator is more than liquid weight in second pipe, lost pressure head is reused and also in first cylinder, first piston moves up charging dead weight accumulator, and lost pressure head is regained. This completes cycle of operation. Image 0/0
