Embodiment 1

[0028] Step 1, close the water inlet and outlet control valves of the η-shaped siphon pipeline 1, start the water pump 4 located under the upstream water surface to draw water to the water source warehouse 7, open the water flow control switch 6 of the pipeline A5, and at this time, other valves of the water source warehouse 7 are closed, so that the water Flow into the n-shaped siphon pipeline 1 through the pipeline A5, inject water for at least one group of n-shaped siphon pipelines, after the n-shaped siphon pipeline is full of water, close the water flow control switch 6, and then open the water outlet control valve 17 of the siphon pipeline 1, and the water inlet control valve 2 means that the check valve will automatically open, and the upstream water flow will continue to flow downstream at this time.

[0029] Step 2. Close the air outlet valve and water outlet valve of the sealed water tank 9, and the water-air combination switch C of the pipeline C12. At this time, the...

Abstract

The invention provides a siphon water drawing pipeline set and a water drawing method through the same. The siphon water drawing pipeline set comprises a plurality of water drawing units composed of siphon pipelines, water source bins, water pumps and sealed water boxes. The siphon water drawing pipeline set is characterized in that each siphon pipeline is an n-shaped pipeline, the two ends of thesiphon pipeline are arranged on the upstream portion and the downstream portion of the riverbed dam section correspondingly, the siphon pipeline tail end located on the upstream portion of the riverbed is provided with a water feeding control valve, the siphon pipeline tail end located on the downstream portion of the riverbed is provided with a water discharging control valve, and the middle section of the siphon pipeline is connected with the corresponding water source bin and the sealed water box in sequence. The siphon pipeline water drawing energy-consumption-free technique is adopted, the effect that siphon energy consumption is close to zero is realized, unmanned water drawing is achieved, operation is safe, in addition, the operation expense of a siphon pipeline pump station is substantially decreased, and an unattended pump station is really achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy drainage and irrigation, in particular to a siphon pumping pipe set and a water pumping method using the pipe set. Background technique [0002] Most of the farmland water is used for gravity irrigation and water pumping irrigation by pumping stations. When water pumps are used for water pumping and irrigation, power consumption, oil consumption, and energy consumption are required. In the mountainous areas of our country, many farmers need water for draft and irrigation. Farmers in mountainous areas watch the mountain streams flow by and can only use human power to carry water for drinking. How to use the mountain stream water to pump water with low energy consumption to high places for irrigation and drinking has always puzzled the vast number of scientific researchers. Therefore, the present invention intends to design a siphon pumping pipeline group and a pumping method using the pi...
