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 river areas on the ground. Background technique [0002] Above-ground river is a concept, and it does not specifically refer to a certain river. When the riverbed is higher than the ground elevation on both banks of the area where the river flows, it is called above-ground river, also known as hanging river. As the water flows to low places, the direction of the water flow is all restricted by the artificial embankments built on both sides of the bank. The most famous surface river in the world is the lower Yellow River. Because it carries a large amount of sediment from the Loess Plateau, after the mainstream of the Yellow River enters the lower flat area with gentle slope, the runoff energy is not enough to transport the large amount of sediment. The riverbed continues to silt up and rise, wi...

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.
