Water discharging device for field ditch irrigation and drainage

Abstract

The invention discloses a water discharging device for field ditch irrigation and drainage. The water discharging device comprises a water discharging retaining wall, wherein a water discharging mechanism is arranged inside the water discharging retaining wall; the water discharging mechanism comprises a first groove, a second groove, a third groove, water outlet holes, fixing rings, L-shaped fixing rods, filter screens, water baffles, circular convex blocks, cavities, fixing plates, threaded rods and rotary discs, wherein the first groove is formed in the top of the front side of the water discharging retaining wall. According to the water discharging device for field ditch irrigation and drainage, through the water outlet holes, the fixing rings and the filter screens in the grooves andthe cavities and the threaded rods in the water baffles, the three water outlet holes can be formed in the water discharging retaining wall, the water baffles are used for sealing the water outlet holes, and the threaded rods can be rotated to move the positions of the water baffles, so that the water discharging amount of the three water outlet holes is adjusted correspondingly; and meanwhile, water is discharged at the three different positions according to needs, due to the arrangement of the cavities, the water baffles cannot rotate along with the threaded rods, and the situation that thethreaded rods cannot be rotated due to the fact that the water baffles rotate along with the threaded rods is avoided.

Description

technical field [0001] The invention relates to the technical field of irrigation and drainage of agricultural canals, in particular to a water discharge device for irrigation and drainage of agricultural canals. Background technique [0002] At present, the control measures for the discharge and outfall of the general field farm canals are very simple, and there are no more than the following methods: simple plug-in type (wooden or concrete), simple wooden plug type, cement plug-in door and so on. For a long time, people have focused their research energy on the planning of field canals, and few people have paid attention to or studied the irrigation and drainage outlets of canals. And often in the design, the types of water outlets selected by each unit are not consistent, and no statistics and research have been done on their use effects. Therefore, in response to this phenomenon, the use of double-layer water outlets for irrigation and drainage of agricultural canals ca...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still some deficiencies in the existing water discharge devices for irrigation and drainage of agricultural canals, for example; Control the amount of water released, and in the process of releasing water, there will be a lot of sundries entering the agricultural canal. Not only that, there will be a lot of silt in the process of releasing water
