Description
Technical field
Hydrology field of measuring techniques is the utility model is related to, is specifically that a kind of utilize determines level of ground water collection measurement effectively drop
The device of water.
Background technology
Effectiv precipitation refers under natural endowment, in any secondary Precipitation Process to land on the ground, precipitation infiltration and energy
The rainfall being stored in root water uptake layer.The calculating of effectiv precipitation is related to the rising steaming in land face in precipitation, Precipitation Process
Infiltrated in hair amount, precipitation and runoff process into soil and be stored in the water in soil, deep percolation.
It is to be obtained using water balance by calculating to determine effectiv precipitation, i.e., the effectiv precipitation of certain rainfall is time drop
Water subtracts surface runoff amount and deep percolation.Because latter two are not easy to determine, the general precipitation with experience effectively utilizes system
Number calculates effective precipitation, and this mode is due to being estimation result, so accuracy is relatively low.
Utility model content
The purpose of this utility model is that providing a kind of utilize determines the device that level of ground water collects measurement effectiv precipitation, should
Device can obtain flow path surface and deep percolation simultaneously, can be accurately calculated with reference to precipitation and Evapotranspiration
Effectiv precipitation, improve the accuracy of result.
Technical scheme is used by the utility model solves its technical problem：
It is a kind of to utilize the device for determining level of ground water collection measurement effectiv precipitation, including rain gauge, meteorological evaporating dish, original state
Soil surveys cylinder, underground water buried depth controller and mariotte flask, underground water buried depth controller bottom by two communicating pipes respectively with
Undisturbed soil surveys cylinder bottom and mariotte flask bottom is connected, the overflow pipe lower end access leakage of underground water buried depth controller
Cylinder；The undisturbed soil is surveyed at the top of cylinder and is provided with outflow tube, and flow path surface cylinder is terminated with outflow tube.
The beneficial effects of the utility model are to obtain the precipitation in one period by rain gauge, are evaporated by meteorology
Ware obtains Evapotranspiration, and the water level that underground water buried depth controller can remain stationary in soil survey cylinder and mariotte flask is kept not
Become, deep percolation is obtained by seepage graduated cylinder, flow path surface is obtained by rainwash graduated cylinder, effective drop is finally calculated
Water, improve the accuracy of result.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model, which provides a kind of utilize, determines the device that level of ground water collects measurement effectiv precipitation, bag
Include rain gauge 1, meteorological evaporating dish 2, undisturbed soil and survey cylinder 3, underground water buried depth controller 4 and mariotte flask 5, underground water buried depth control
The bottom of device 4 processed is surveyed the bottom of cylinder 3 with undisturbed soil by the first communicating pipe 6 and is connected, by the second communicating pipe 7 and mariotte flask 5
Bottom is connected, and overflow pipe 8, the lower end of overflow pipe 8 access seepage graduated cylinder 9 are provided with underground water buried depth controller 4；The undisturbed soil
Survey the top of cylinder 3 and be provided with outflow tube 10, flow path surface cylinder 11 is terminated with outflow tube 10.
Undisturbed soil is surveyed cylinder 3 and is made by steel plate or stainless steel plate, and shape can be cylinder or cuboid, crop
Root system depth be generally 0.5m or so, undisturbed soil surveys the high 0.8~1.0m of cylinder, depending on actual conditions.Outflow tube 10 is higher by
Undisturbed soil surveys 0.0~0.05m of soil in cylinder, can be made of rubber hose, diameter 5cm, as the drainage pipeline of rainwash, be
Sediment Siltation is prevented, often to safeguard, dredging pipeline, avoid blocking.
Underground water buried depth controller 4 is open-top receptacle, and it can be made of lucite with mariotte flask 5, is shaped as justifying
Cylinder；First communicating pipe 6 was made with the second communicating pipe 7 of rubber hose, diameter 5cm.
When precipitation occurs, part precipitation can form rainwash, be entered by outflow tube 10 in rainwash graduated cylinder 11；
Other waters may proceed to infiltrate the supply soil water, after the soil water meets unsaturation band soil water storage（Reach field capacity
Afterwards）, unnecessary water is by lower impregnation to the underground water in the soil body, and the water level that undisturbed soil is surveyed in cylinder 3 and underground water buried depth controller 4 is all
It can rise, be controlled by the height of overflow pipe 8, unnecessary water enters seepage graduated cylinder 9 by overflow pipe 8 in underground water buried depth controller 4
In, until water level recovery initial value, i.e., keep flushing with the top of overflow pipe 8.
Precipitation in one period is obtained by rain gauge 1, Evapotranspiration is obtained by meteorological evaporating dish 2, by oozing
Leakage quantity cylinder 9 obtains deep percolation, and flow path surface is obtained by rainwash graduated cylinder 10, eventually through principle of water balance,
Evapotranspiration, deep percolation and flow path surface are subtracted from precipitation effectiv precipitation is calculated.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation；Any those skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to of the present utility model
Technical spirit still falls within this practicality to any simple modification, equivalent substitution, equivalence changes and modification made for any of the above embodiments
In the range of the protection of new technique scheme.
