Description

Technical Field

[0001] The utility model relates to the technical field of irrigation water diversion devices, in particular to a portable gravity irrigation siphon water diversion device. Background Art

[0002] In gravity-flowing farmland, the height of the main canal is higher than the height of the farmland. During irrigation, river water will be introduced into the main canal, thereby diverting the water in the main canal to the farmland for irrigation. In some areas, there is a road between the main canal and the farmland, so some auxiliary settings are needed to divert the water in the main canal to the farmland. A common method is to open a water channel under the road and build a gate at the entrance of the channel. However, this setting is complex to build and has high construction costs. The gate is easily destroyed when the water pressure is high, and some plots are not suitable for the construction of sluices. Another method is to bury a water diversion pipe under the road, and use a water pump to divert the water in the main canal into the water diversion pipe, and then into the farmland. This method requires farmers to purchase water pumps, which makes farmers' procurement and operation costs high, and they are easy to lose in the wild. At the same time, they also need electricity support, which is not applicable in the wild where electricity is inconvenient.

[0003] Therefore, a portable gravity irrigation siphon water suction device is proposed. Utility Model Content
