Description of the drawings
Fig. 1 surveys effluent level measuring arrangement structure diagram for a kind of farmland discharging-irrigating experiment described in the utility model.
Specific embodiment
Illustrate the content of the utility model below in conjunction with specific embodiments.
As shown in Figure 1, survey effluent level measuring arrangement structural representation for a kind of farmland discharging-irrigating experiment described in the utility model
Figure.
Effluent level measuring arrangement is surveyed in a kind of farmland discharging-irrigating experiment that the present embodiment is provided, including：It surveys hole 10 and connects institute
The par device 20 for surveying hole 10 is stated, the bottom for surveying hole 10 and the bottom of the par device 20 are in same level, and described
It surveys between the bottom in hole 10 and the bottom of the par device 20 and is connected by communicating pipe 30, the bottom for surveying hole 10 is provided with filter
Layer 11, connects the filtering layer 11 communicating pipe 30, is provided with pressure type water gauge 31 on the communicating pipe 30 and connects valve
32, and the pressure type water gauge 31 is located at the connection valve 32 and described survey is cheated between 10.
Specifically, 10 top of hole of surveying is provided with irrigation rig 12.21 He of water inlet pipe is connected on the communicating pipe 30
Drainpipe 22, and the water inlet pipe 21 and the drainpipe 22 connect valve 32 with the junction of the communicating pipe 30 positioned at described
Between the par device 20.Feed water flow gauge 23 and entering water electromagnetic valve 24, the drainpipe are provided on the water inlet pipe 21
Drain flow-meter 25 and drain solenoid valve 26 are provided on 22.
Preferably, the connection valve 32 is electrical ball valve.Due to the pressure surveyed between hole 10 and the par device 20
Difference is smaller, therefore the connection valve can select electrical ball valve, and compared to normally open solenoid valve, electrical ball valve can ensure " zero
