Abstract

The invention provides an energy-gathering pumping device with an air inflow controlling ball valve, and a pumping method. The device comprises an eta-shaped pipeline, a Venturi pipe, negative pressure pipelines, a pumping pipeline and a sealed water storage tank, wherein a water inlet of the eta-shaped pipeline is located upstream, and a water outlet is located downstream; a water inlet end of the Venturi pipe is located below a downflow weir, and an water outlet is located on the downstream liquid surface; the top of the eta-shaped pipeline and the narrowest part of the Venturi pipe communicate with the sealed water storage tank through the negative pressure pipelines provided with negative pressure valves; the side of the sealed water storage tank communicates with an upstream water source through the pumping pipeline provided with a sealed water storage tank valve, the air inflow controlling ball valve and a pumping pipeline valve; a ventilation valve is arranged at the upper partof the sealed water storage tank, and the bottom of the sealed water storage tank is connected to a buoyancy valve and a water faucet. The energy-gathering pumping device has the advantages that energy of the flow drop between the upstream and downstream of the mountain stream can be used to pump water, unattended pumping can be achieved after a siphon is started, and thus, operation is safe, related expenses on administrative staff in a pump station are greatly reduced, and unattended management for a pump station is truly achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy drainage and irrigation, in particular to an energy-gathering water pumping device and a water pumping method with a ball valve for controlling the amount of air intake. Background technique [0002] Considering economic factors, my country seldom sets up pumping stations in places where the water head difference is less than 6m, which makes it difficult to use water conveniently in rural areas in remote areas; , need to consume a lot of fuel or electric energy. Therefore, how to improve the pumping efficiency, reduce the energy consumption of irrigation and drainage or not rely on electricity consumption, and how to improve the overall economics of the device has been perplexing the majority of scientific researchers. The Chinese invention patent with the application number CN201510647572.3 provides "a kind of energy-gathering water pumping device and water pumping method", including mu...
