A second water tank 25 is provided at the bottom end of the second connecting rope 24.

[0026] The piston 6 moves left and right in the piston chamber.

[0027] When the piston 6 moves to the left, the first water tank 23 moves downward.

[0028] When the piston 6 moves to the right, the second water tank 25 moves downward.

[0029] When the present invention is implemented, a water tank is filled with water and sinks, and the first connecting rope is pulled to drive the connecting rod to move to the left. At this time, the second air inlet valve is closed, the volume of the second water chamber increases to generate negative pressure, and the second check valve is opened, and water enters the second water chamber from the water inlet chamber.

The second water tank is filled with water and sinks, and the second connecting rope is pulled to drive the connecting rod to move to the right, the first air inlet valve is closed, and the volume of the first water chamber increases to generate negative pressure. The first check valve is opened, and water enters the first water chamber from the water inlet chamber. When the piston moves to the right to the limit, the second water tank is drained, the first air inlet valve is opened, and the first water chamber flows to the first water tank through the first water pipe. The two water tanks are alternately filled with water, and gravity is used to drive the piston to reciprocate to achieve continuous pumping.

[0030] Working principle of the present invention:

[0031] 1. Siphon effect: When the piston moves, the volume of the water chamber changes to form a pressure difference, which is combined with the check valve to control the direction of water flow.

[0032] 2. Gravity drive: The gravity of the falling water tank is converted into piston power through the pulley system, reducing manpower input.

[0033] The present invention combines gravity and siphon effect by optimizing the mechanical structure to achieve efficient and energy-saving agricultural irrigation, and is particularly suitable for promotion and use in power-deficient areas.

[0034] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
