The buoy is vertically arranged in the water tower. The buoy is a stainless steel buoy. The top ends of the water towers are respectively provided with vent holes and communicated through a communication elbow. The communicating elbow pipe enables hydraulic pressure or air pressure at the tops of the two water towers to be communicated, mutual force assistance is achieved, and capacity consumption is saved. The water inlet valve seat is arranged in the communicating port and sleeved with the top end of the cylinder sleeve, and the water inlet valve seat is provided with a water inlet one-way valve. The water inlet one-way valve can be opened upwards and stopped downwards. The bottom end of the push rod is sleeved in the cylinder sleeve and is fixedly connected with the top end of the piston, and the top end of the push rod extends into the water tower. The waterproof sleeve is sleeved outside the push rod and is fixedly connected with the water inlet valve seat. Two round waterproof grooves are arranged in the waterproof sleeve, and waterproof rings are assembled in the waterproof grooves to prevent water from entering the crankcase through the cylinder sleeve.

The piston disc is sleeved in the inner cavity at the bottom of the water tower and is fixedly connected with the top end of the push rod. The piston disc moves up and down in the inner cavity at the bottom of the water tower to press water and lift water.

The water outlet is arranged on the side part of the piston chamber at the top of the water tower. The outer diameter of the middle buoy is smaller, so that water can be discharged from a water outlet conveniently. The water flow squeezed upwards by the pontoon rises to the water outlet through the space between the main part pontoon and the inner wall of the water tower. When the top buoy leaves the water outlet, water in the water tower is extruded and discharged from the water outlet, and the discharged water enters the water turbine to drive the water turbine to operate.

As shown in figures 2 and 3, the centers of the top ends of the water towers are respectively provided with a linear bearing. A central pipe is connected between the upper end and the lower end of the float bowl in a penetrating way. The central pipe is positioned at the central axis of the buoy.
