Siphon irrigation system and siphon irrigation method

Abstract

The invention provides a siphon irrigation system and a siphon irrigation method. The siphon irrigation system is mounted at a suspended river or in a river and lake area with water surface altitude higher than ground altitude and comprises a siphon water inlet device, an irrigation water treatment device, a proportioning device and an irrigation device, wherein a water inlet end of the siphon water inlet device is arranged in the river, a water outlet end of the siphon water inlet device is connected with a water inlet end of the irrigation water treatment device, and the altitude of the water inlet end of the siphon water inlet device is higher than that of the water outlet end of the siphon water inlet device; a water outlet end of the irrigation water treatment device is connected with a water inlet end of the proportioning device, and a water outlet end of the proportioning device is connected with the irrigation device. With adoption of the siphon irrigation system, water can be introduced into an irrigation area by means of a siphonic effect without ditch excavation, irrigation water is decontaminated, energy saving and emission reduction are realized, and safety and sanitation are realized.

Description

technical field [0001] The invention relates to the technical field of farmland water conservancy, in particular to a siphon irrigation system and a siphon irrigation method suitable for aboveground river areas. Background technique [0002] Above-ground river is a concept, not specific to a certain river. When the altitude of the river bed is higher than the ground altitude of the two sides of the area where the river flows through, it is called an above-ground river, also known as a suspended river. Since the water flows downhill, the direction of the water flow is completely restricted by the artificially built embankments on both banks. The most famous aboveground river in the world is the lower reaches of the Yellow River. Due to carrying a large amount of sediment from the Loess Plateau, after the main stream of the Yellow River enters the downstream plain area with a gentle slope, the runoff kinetic energy is not enough to transport the large amount of sediment it ca...

AI Technical Summary

Problems solved by technology

[0003] At present, people around the above-ground river usually irrigate by digging ditches from the above-ground river to the farmland, and diverting the river water from the above-ground river to the farmland. It is easy to cause damage to the embankment of the above-ground river, and the risk factor is high, which is likely to cause casualties. Moreover, since the above-ground river is mostly located in the lower reaches of the river, there are more garbage and toxic substances than in the middle and upper reaches of the river. The pollution is serious. If the river water is directly used for irrigation, the plants may be polluted accordingly, which will further affect the health of humans and animals.
