An efficient floating-aid lifting liquid pumping device having a large capacity and a high head, the device comprising a frame (1), a water storage tank (8), a pump body device, a pump core device and a lifting device; the pump body device comprises a water drawing trap (2), a pumping valve device (4), a water draining trap (3) and a high-level water tank (11); the water drawing trap (2) is provided with a buffering and boosting device (35) at a bottom portion thereof; the water draining trap (3) is provided with a floating-aid trap (12) outside in communication with and cooperating with the high-level water tank (11); the floating-aid trap (12) is provided with a water draining pipe (23) at a bottom portion thereof, and is provided with a floating-aid chamber (14) therein; the floating-aid chamber (14) is connected to a hoist roller (15) of the lifting device via a floating-aid rope (13); the pump core device comprises a piston chamber (5) and a counterweight chamber (6) above the piston chamber (5); and the piston chamber (5) is sealed from and movably fitted to the pumping valve device (4) via a floating sealing ring (7). The pumping device draws or drains water based on a space occupation ratio of the buoyancy balance-type piston chamber, and reduces a lifting resistance to the pump core device and energy consumption of the lifting device by using the floating-aid chamber of the floating-aid trap to drive the counterweight chamber to float up together via the lifting device, thus effectively lifting water to a position having high potential energy, and delivering a large volume of water into a water consuming device or a power conversion device. |
