A floating-assist lifting type large-capacity high-lift liquid high-efficiency pumping device

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of liquid pumping equipment, and in particular relates to a buoyancy-assisted lifting type large-capacity high-lift high-efficiency liquid pumping device capable of efficiently and quickly pumping large-capacity liquid to a high place. Background technique [0002] Water is not only the basis for people's survival, but hydraulic energy is a renewable energy source, which provides great convenience for human production and life. The traditional hydraulic energy utilization method usually utilizes the potential energy formed by the natural drop of the river, that is, through the conversion of hydraulic potential energy to kinetic energy, it impacts the low-level water turbine to generate electricity. Of course, there is also a hydropower utilization method that uses ocean tidal energy to generate electricity. However, these utilization methods all depend on natural geographical conditions, and objectively, th...
