Specific embodiment
As shown in Figs 1-4, field irrigation mechanism of the present invention, it includes mainly including water unit 1 and outlet gate 2, wherein
Water unit 1 includes the closed conduit 3 below roadbed, and closed conduit 3 is connected to by water pipe 4 with outlet gate 2；Outlet gate 2 includes outer
The lower section of shell 21, shell 21 is connected to by water pipe 4 with closed conduit 3, and the top of shell 21 is equipped with outlet pipe 5, is equipped with branch in shell 21
Fagging 6 is equipped with light material above support plate 6 and opening and closing plate 7 is made, and opening and closing plate 7 is equipped with drainpipe 8, and support plate 6 is equipped with water
Discharge orifice 9, opening and closing plate 7 be freely pressed in support plate 6 and be completely covered water flow hole 9,8 sets of drainpipe in outlet pipe 5, drainpipe
8 end is higher than outlet pipe 5；The support plate 6 is fixed on the inner wall of shell 21, and support plate 6 and shell are stayed between 21 bottom
There is gap 10.
Working principle: when needing to irrigate, the water in closed conduit can be rushed in outlet gate, and water flow is flushed to support first
In the gap 10 of 6 lower section of plate, water flow gives opening and closing plate buoyancy by water flow hole 9, and then, opening and closing plate floats under buoyancy,
Water flow up can pour into farmland by outlet pipe, realize the irrigation to farmland, since draining tube end is higher than outlet pipe, because
This, the water in farmland will not be leaked out from drainpipe.During irrigation, if the water level in farmland is mutually agreed to level pressure in closed conduit
Taste irrigate complete, at this moment the water flow in outlet gate is motionless, opening and closing plate begun to decline under Gravitative Loads, when most of farmlands
After the completion of irrigation, the hydraulic pressure in closed conduit can decline, and then open and close water of the plate in self weight and farmland and be total to by what water outlet was flow backwards
Offset with support plate rapidly the water flow hole blocked in support plate under same-action, then, sealing is just formed above shell inner support plate
Gate action is played in space, is irrigated and is completed.When raining etc. under situations, farmland water level rises, when be more than this value of certain value according to
When the different set difference of crops, water level will be more than drainpipe, and excessive water will be discharged from drainpipe in farmland, keep away
Exempt from damage caused by waterlogging.Equally it is automatically performed, it is time saving and energy saving.
To achieve the above object, the opening and closing plate 7 is integrated with drainpipe 8, and the opening and closing plate 7 is greater than in support plate 6
Water flow hole 9.Opening and closing plate and drainpipe all use makings material, as long as will not deform under the effect of farmland hydraulic pressure.Certainly,
Opening and closing plate and drainpipe are also possible to partial installation structure, or even be made can also be with as long as of the invention former for different same materials
The object of the invention can be completed on the basis of reason.
Sealing effect true is played in order to enable opening and closing plate accurately to cover the water flow hole in support plate, in institute
Several limit plates 11 are additionally provided in the shell 21 stated, limit plate 11 is connect with 21 side wall of shell, and limit plate 11 is waffle slab, opening and closing

At interstitial site between pipe 8.It there is also another situation is exactly to flow backward in reality, water in farmland is many or even super
Drainpipe is crossed, but since outside water presses through height, leads to hydraulic pressure in closed conduit also superelevation, in this case, opening and closing plate will
It is sufficiently jacked up, under normal circumstances, no matter how high the hydraulic pressure sent in closed conduit is, as long as opening and closing plate floats water flow and enters
Farmland, the hydraulic pressure in shell would not be excessively high, and whole device, which can work normally, plays farmland water control action, but works as
In the case that hydraulic pressure is excessively high in closed conduit, and farmland has also been filled, opening and closing plate will float to shell under buoyancy will go out
The mouth of a river is blocked, and Contact Seal ring can more preferably realize the closing of water outlet, to realize the purpose for preventing flowing backward.If opening and closing plate
Float to shell topmost, the water in closed conduit can also enter farmland from drainpipe, and situation is exactly to belong to special circumstances, illustrates water conservancy
System problem is not the problem of this mechanism is able to solve.Moreover such case belongs to extreme case, probability it is small and one it is found that
The mode that can be cut off the water supply from source solves.
