Energy gathering pumping device and pumping method thereof

Abstract

The invention provides an energy gathering pumping device which comprises multiple groups of n-shaped pipelines, a water injection cabin, a water injection pipeline, a negative pressure pipeline, a pumping pipeline and a sealing water tank, wherein the water injection cabin is communicated with a water injection pump in an upstream water source by a water pump pipeline; the tops of the multiple groups of n-shaped pipelines are respectively communicated with a water source cabin by the water injection pipeline provided with a water injection pipeline valve; the tops of the multiple groups of n-shaped pipelines are communicated with the sealing water tank by the negative pressure pipeline provided with a negative pressure pipeline valve; the side part of the sealing water tank is communicated with a downstream water source by the pumping pipeline provided with a pumping pipeline valve; a ventilating valve is arranged at the upper part of the sealing water tank, and a water discharge pipeline provided with a water discharge valve is arranged at the lower part of the sealing water tank. The device has the advantages of achieving the effect that energy consumption approaches to zero, realizing unattended operation in pumping, being safe in operation, greatly reducing relative charge against revenue for pump station managers, and truly achieving unattended management for the pump station.

Description

technical field [0001] The invention relates to the technical field of water conservancy drainage and irrigation, in particular to an energy-gathering pumping device and a pumping method. Background technique [0002] Most of the water used in farmland is irrigation by artesian irrigation and water pumping by pumping stations. When water pumps are used for water pumping and irrigation, power consumption, oil consumption, and energy consumption are required. During the flood season, a large area of ​​farmland is flooded, and quick drainage is the top priority for farmers. However, due to damage to power facilities and road collapse, irrigation stations cannot operate normally, resulting in huge losses in agriculture. How to improve the pumping efficiency, reduce the energy consumption of drainage and irrigation or not rely on electricity consumption has always puzzled the vast number of scientific researchers. Contents of the invention [0003] The object of the presen...

Problems solved by technology

[0002] Most of the farmland water is used for self-flow irrigation and water pumping irrigation. When the water pump is used for water pumping and irrigation, it needs power consumption, oil consumption, and energy consumption.

During the flood season, a large area of ​​farmland is flooded with water, and fast drainage is the top priority for farmers. However, due to the damage of power facilities and road collapse, the irrigation stations cannot operate normally, which eventually leads to huge losses in agriculture.
