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, and rapid drainage is the top priority of farmers. However, due to the damage of power facilities and road collapse, the irrigation and drainage stations cannot operate normally, which eventually leads to huge losses in agriculture.

Embodiment 1

[0019] (1) Place the ?-shaped water pipeline so that one end of the water inlet control valve is located upstream, and its port is located below the water surface, and the other end with the water outlet control valve is located downstream, and its port is lower than the upstream water surface and higher than the downstream The water surface; the port at one end of the water delivery pipeline (1) water inlet control valve (2) is provided with a trash cover (3);

[0020] (2) Close the water inlet control valve and water outlet control valve of the ?-shaped water delivery pipeline, start the water pump located under the upstream water surface to draw water to the water source warehouse, and turn on the water flow control switch A of pipeline A. At this time, other valves of the water source warehouse are closed, so that Water flows into the square-shaped water pipeline through pipe A, and fills at least one set of square-shaped pipes with water. After the square-shaped water pipe...

Abstract

The invention provides a water drawing device and a water drawing method using the water drawing device. The water drawing device comprises a water delivery device, a water source tank and a water pump. The water delivery device comprises a water delivery pipe and a sealed water tank. When the water drawing device runs, multiple places can be irrigated at the same time or water can be drained through multiple pipes at the same time, time is saved, the irrigation efficiency and the water draining efficiency are improved, and then the losses caused when irrigation or water draining is not carried out in time are reduced; and energy consumption can tend to zero, unattended water drawing can be achieved, running can be safe, the related expense of pump station managing persons is greatly reduced, and unmanned management of pump stations is really achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy drainage and irrigation, in particular to a pumping device and a pumping method using the device. 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, large tracts of farmland are flooded, and quick drainage is the top priority for farmers. However, due to damage to power facilities and collapsed roads, drainage and irrigation stations cannot operate normally, resulting in huge losses in agriculture. How to improve the pumping efficiency and reduce the energy consumption of drainage and irrigation has been perplexing the vast number of scientific researchers. Contents of the invention [0003] The purpose of the present invention is to provide...
