A river water introduction and diversion device for pressurized water inflowing farmland water conservancy irrigation ditches

Abstract

The invention discloses a pressurized water inflow type river water introduction and guiding device for a farmland irrigation ditch. The pressurized water inflow type river water introduction and guiding device structurally comprises a diversion connection horizontal plate, a longitudinal positioning plate, a fixed cross beam, pressurized guiding devices and water diversion and collecting devices.The pressurized water inflow type river water introduction and guiding device has the effects that through the cooperation of the pressurized guiding devices and the water diversion and collecting devices, limited pressurization and guiding can be realized on the introduced water body, so that the pressurized water body is uniformly irrigated to the farmland from near to far through the water diversion ditch, and uneven irrigation of each farmland due to insufficient water pressure of the introduced water body is prevented.

Description

technical field [0001] The invention relates to the technical field of farmland water conservancy equipment, in particular to a river water introduction and diversion device for pressurized water inflow of farmland water conservancy irrigation ditches. Background technique [0002] Large-scale rice planting requires digging ditches for irrigation in the field to facilitate the introduction of nearby river water into the ditch, and the water body is introduced into the farmland through the dug ditches to meet the needs of rice growth. However, the connection between the ditch and the river is generally closed. The gate blocks the river water from entering the ditch, and when the gate is opened, the river water is introduced into various farmlands through the ditch. The gate is mainly used to close and open the drainage channel, but the discharge port formed when the gate is opened cannot realize the pressurization and diversion of the incoming water body, resulting in Due to ...

[0002] Large-scale rice planting requires digging ditches for irrigation in the field to facilitate the introduction of nearby river water into the ditch, and the water body is introduced into the farmland through the dug ditches to meet the needs of rice growth. However, the connection between the ditch and the river is generally closed. The gate blocks the river water from entering the ditch, and when the gate is opened, the river water is introduced into various farmlands through the ditch. The gate is mainly used to close and open the drainage channel, but the discharge port formed when the gate is opened cannot realize the pressurization and diversion of the incoming water body, resulting in Due to insufficient water pressure, the introduced water body cannot be concentrated and will spread to both sides, resulting in sufficient water for the farmland near the junction of the diversion ditch and the river body, and insufficient water for the distant farmland, resulting in The uneven irrigation of each piece of farmland affects the yield. Therefore, it is necessary to develop a river water introduction and diversion device that can increase and divert the incoming water body, so as to prevent the incoming water body from being diverted to the direction due to insufficient water pressure. Diffusion on both sides, resulting in uneven irrigation of each piece of farmland
