Hydraulic gravitational pressure generating method and equipment

The invention relates to a hydraulic gravitational pressure generating method and equipment. The equipment comprises a double-track annular railway line and a trough carriage running on the railway line, wherein pressure plates are uniformly arranged on the double-track annular railway line; a spring is arranged between the double-track annular railway line and each pressure plate; the pressure plates are connected with force rods; the force rods are connected with stressed arm rods of a speed increaser; the stressed arm rods of the speed increaser are connected with a transmission gear of the speed increaser and are arranged in a shape of a waterwheel; the transmission gear of the speed increaser is connected with a rotating shaft of a generator; the generator is connected with a controller; wheels are installed below the trough carriage; and the wheels run on the double-track annular railway line to press spring pressure plates for doing work to form a mechanical chain. In the generating method, the vertica
