Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Embodiment one
Fig. 1 is the structural representation of the utility model agricultural run-off draining original position metering monitor embodiment one, and during use, the water inlet pipe angle end that hangs down is arranged on farmland surface bottom.Described agricultural run-off draining original position metering monitor comprises filter screen 1, water inlet pipe 2, metering water meter 3, rising pipe 4 and dust-collecting bucket 5.Described water inlet pipe 2 is the middle L-type pipe having 90 ° of right angles, is formed by connecting by two pvc pipes 90 ° of elbows.The water inlet pipe 2 angle end that hangs down is arranged on farmland surface 7 bottom, and water inlet pipe 2 is positioned at farmland surface 7 top tubing opening upwards, and nose end level is equipped with filter screen 1, enters in pipe to intercept foreign material.Described rising pipe 4 is the middle Z-type pipe having two 135 ° of turnings, place, and being linked and packed with two 135 ° of elbows by three pvc pipes forms.The endpiece of described water inlet pipe 2 is connected with the entrance point of described rising pipe 4 by described metering water meter 3, and the endpiece of described rising pipe 4 is communicated with described dust-collecting bucket 5.
Described metering water meter 3 adopts sunk type to lay mode, and described metering water meter 3 present position, lower than the mouth of pipe height of water inlet pipe 2 and rising pipe 4, makes water meter overall lower than water meter fluid-tight line 8.Described rising pipe 4 is consistent with the pipe diameter size of described water inlet pipe 2, and with metering water meter 3 flows match, simultaneously the open height of rising pipe 4 is lower than the open height of water inlet pipe 2.Described dust-collecting bucket 5 can be column type Plastic Drum, and it is neglected greatly sampling quantity demand and determines.
Use this device original position to measure and monitor agricultural run-off draining and comprise the steps:
1) according to target farmland block size, the dust-collecting bucket 5 that the metering water meter 3 selecting uninterrupted moderate, the PVC of suitable caliber and capacity are moderate.The drain outlet preset in farmland excavates the hole of the rectangle through a ridge groove in advance.Ready-made L-type water inlet pipe 2 arranged orthogonal will be shifted to an earlier date in the groove of hole, farmland surface 7 bottom is imbedded in water inlet pipe 2 angle part of hanging down, buried depth is depending on farmland Soil surface water overflow height demand for control, keep water inlet pipe 2 opening upwards, in vertical state, again filter screen 1 level is installed on the openend of water inlet pipe 2, enters in pipe to intercept foreign material;
2) water inlet of the metering water meter 3 selected is installed in the endpiece of water inlet pipe 2, more in advance ready-made Z-type rising pipe 4 is installed in the water outlet end of metering water meter 3.Guarantee the mouth of pipe height of metering water meter 3 present position lower than water inlet pipe 2 and rising pipe 4 after installation, make its entirety lower than water meter fluid-tight line 8, during water flowing, water meter is in and completely stays state; Guarantee the open height of the open height of rising pipe 4 lower than water inlet pipe 2 simultaneously, make current self-assembling formation pressure differential, prevent the water in dust-collecting bucket 5 from flowing backwards;
3) dust-collecting bucket 5 side wall upper part selected is bored a circular hole, aperture comparatively rising pipe 4 external diameter is slightly large, is hinged with rising pipe 4 to dust-collecting bucket 5, makes it extend in bucket through circular hole through bucket wall, ensures that agricultural drain can flow in bucket smoothly.Dust-collecting bucket 5 is placed on outside ridge and has dug in heatable adobe sleeping platform, and top is furnished with a detachable dust-collecting bucket bung 6.After device installs, guarantee that water inlet pipe 2, metering water meter 3, rising pipe 4 and dust-collecting bucket 5 are on same straight line, and backfill the soil body, stationary installation;
4) farmland forms runoff after meeting with rainfall, when the water surface rises to the Soil surface water overflow height of setting, runoff enters in water inlet pipe 2 through filter screen 1, metering water meter 3 is flow through through water inlet pipe 2, (circular hole of rising pipe 4 through dust-collecting bucket 5 side extends in bucket through bucket wall) in dust-collecting bucket 5 is flowed into again through rising pipe 4, after rainfall terminates, the volume of this runoff draining is obtained by the reading of metering water meter 3, open dust-collecting bucket bung 6 simultaneously and gather water sample, after sampling, water remaining in dust-collecting bucket 5 is poured out, in order to sampling next time.
Embodiment two
Fig. 2 is the structural representation of the utility model agricultural run-off draining original position metering monitor embodiment two, and during use, the water inlet pipe angle end that hangs down is arranged on farmland surface top.The present embodiment two and embodiment one are distinguished and are, the vertical angle end of water inlet pipe 2 is arranged on farmland surface 7 top.Water inlet pipe 2 hangs down angle end when being arranged on farmland surface 7 top, the angle tilted by adjustment water inlet pipe 2 overground part tubing adjusts the height of the mouth of pipe apart from farmland surface 7, thus realize any control of Soil surface water overflow height, be particularly useful in plant growing process or gather in the crops the situation that front farmland needs artificial drainage.
In above embodiment, also according to actual conditions, agricultural run-off draining original position metering monitor each several part can be shifted to an earlier date complete by assembling shown in Fig. 1 in indoor, and then the utility model is moved to targeted test field digging in-situ groove, carry out Matching installation.
This device coordinates assembling to measure the agricultural drain of different area by the metering water meter of the pvc pipe and different flow of selecting different tube diameters, farmland Soil surface water overflow height is controlled apart from the height on earth's surface or the angle of adjustment water inlet pipe overground part tubing inclination by the adjustment water inlet pipe mouth of pipe, by the runoff draining water sample selecting the dust-collecting bucket of different capabilities to gather varying number, be applicable to the original position measure monitor research of the runoff draining in the dark and Different Diameter stream load farmland of different field area, different Soil surface water.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
