Abstract

The invention discloses a canal-irrigation-area pipe water delivery irrigation system, relates to irrigation of hydraulic engineering and particularly relates to irrigation for canal irrigation areas. The irrigation system comprises a water source (11), a first pipe (12), a water inlet gate (13), a ventilation hole (14), a ventilation pipe inlet port (121), a ventilation pipe (15), a water distribution pressure reduction pool (21), a water inlet pipe (22), a water outlet pipe (23), a first flexible joint (221), a beam (24), a shaft sleeve (25), a rocker arm (26), a first hinge pin (261), a valve rod (27), a circular plate (271), a sealing ring, a second hinge pin (262), a floating ball rod (28), a floating ball (281), a limit rod (29), a rod base (291), a second pipe (31), a second flexible joint (231) and a hydrant (32). The irrigation system can be applied to canal irrigation areas and is capable of performing irrigation according to irrigation requirements and water saving.

Description

technical field [0001] The invention relates to irrigation in water conservancy projects, in particular to irrigation for canal irrigation areas. Background technique [0002] Using pipelines instead of open channels for water delivery irrigation has the advantages of water saving, land saving, labor saving, time saving, power saving, timely irrigation, and strong terrain adaptability. In my country's well irrigation areas, restricted by the condition that the well's output flow is small, the pipe network water delivery irrigation system is usually an application mode of "single well - trunk and branch pipelines with the same pipe diameter - field water supply plug", which is simple and easy to learn. , the technology is relatively mature, so the low-pressure pipeline water delivery irrigation engineering technology has been popularized and applied in a large area in my country's well irrigation areas. However, in canal irrigation areas, that is, self-flowing irrigation area...
