Abstract: A buoyancy-driven liquid pumping device having a constant volume and a use method thereof. The liquid pumping device comprises a float (1), a driving force amplification mechanism (2), a piston assembly (3), a liquid container (4), and a liquid suction pipe (5). A first liquid (7) capable of generating buoyancy for the float after a liquid level rises is stored outside the float (1). The float (1) is connected to the driving force amplification mechanism (2). The piston assembly (3) comprises a piston (31) and a piston sleeve (32). The driving force amplification mechanism (2) is connected to the piston (31). A second liquid (8) is contained in the liquid container (4). The liquid suction pipe (5) is provided in the liquid container (4). A resultant force applied to the float (1) is amplified by the driving force amplification mechanism (2) and the amplified resultant force drives the piston (31) to slide in the piston sleeve (32), so as to generate a suction force or thrust, such that a constant amount of second liquid (8) in the liquid container is pumped and discharged. The invention effectively converts the buoyancy generated by the first liquid having a regularly varying liquid level into a driving force for driving the liquid pumping device, and does not require additional manual or electric driving, thereby achieving automatic, fixed, resource-conserving, and cost-reducing pumping of the second liquid.
