Description
Technical field
The utility model relates to field of water quality detection, particularly relates to a kind of water-head pick-up unit for measuring underground water and surface water water-head.
Background technology
In recent years, the development of industrialzation and urbanization pollutes aggravation, and cause sewage crossing current in many rivers, irrigation canals and ditches, earth's surface forms large amount of sewage seepage pit, and " having water all dirts " has become a universal phenomenon at northern area.Close hydraulic connection is there is between surface water and groundwater, when surface water water level is higher, surface water supply underground water, on the contrary recharge of ground water surface water, supply intensity is directly related with both water-heads.Therefore, by measuring earth's surface polluted-water and the water-head of underground water in the boring be adjacent, the recharge connection between them can be learnt, and further clear and definite groundwater contamination scope and pollution level.Existing technology obtains both water-heads by measuring surface water and groundwater water surface absolute altitude respectively, but there is following two problems: the first, the measuring method of surface water and groundwater is different, and be two independently processes, cause resultant error larger, in less location of some surface water and groundwater water-heads itself, error range may exceed actual value; The second, the measurement of long-term sequence can not be carried out, therefore can not describe the dynamic change of both recharge connections and supply intensity.
Therefore, necessaryly a kind of new water-head pick-up unit is provided to solve above-mentioned technical matters.
Summary of the invention
The technical matters that the utility model solves is to provide a kind of water-head pick-up unit, detects the problem causing error larger because measuring method is different to improve in prior art to the water-head of underground water, surface water.
For solving the problems of the technologies described above, the utility model provides a kind of water-head pick-up unit, comprise be placed in underground water box body, be arranged in the first water pipe that pair of sensors bottom box body and two ends are connected to box body and surface water respectively; A described sensor is provided with towards the sensitive surface of tray interior, and another sensor is provided with towards the sensitive surface of box portion outside; The sensitive surface of described two sensors is positioned in same level.
As the further improvement of the technical program, the sensitive surface of a described sensor is arranged upward, for detecting level pressure in box body; The sensitive surface of another sensor described is arranged down for detecting the outer level pressure of box body.
As the further improvement of the technical program, sensitive surface and the internal face bottom box body of described two sensors keep flushing.
As the further improvement of the technical program, the top of described box body is connected with the second water pipe, and described first water pipe, the second water pipe are communicated to tray interior respectively, and the water level in described second water pipe keeps flushing with earth's surface water level.
As the further improvement of the technical program, described water-head pick-up unit also comprises a pair automatic switch being positioned at the first water pipe two ends for a pair.
As the further improvement of the technical program, the bottom of described box body is also provided with filter screen.
The utility model utilizes law of connected vessels, what adopt box body and water pipe is arranged so that level pressure in box body and earth's surface level pressure are consistent, the level pressure inside and outside box body can be detected thus by the sensor of two bottom box body simultaneously, and the level pressure obtaining surface water and groundwater is poor, whole process more becomes more meticulous and robotization, and has unified the pressure test mode to surface water and groundwater.
Accompanying drawing explanation
Fig. 1 is the using state figure of water-head pick-up unit described in the utility model.
Fig. 2 is the inner structure schematic diagram of the box body of water-head pick-up unit in Fig. 1.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of water-head pick-up unit, comprise a box body 10, be positioned at pair of sensors bottom box body 10 21,22, be connected to bottom box body 10 respectively and first water pipe 30 at top and the second water pipe 40 and be positioned at a pair automatic switch 50 at the first water pipe 30 two ends for a pair.
Described box body 10 is placed in underground water table and detects in well 200, and described pair of sensors 21,22 is all arranged at bottom described box body 10, and described sensor 21,22 is equipped with a sensitive surface.Wherein, a sensor 21 is arranged on the internal face bottom box body 10, and the sensitive surface 23 of this sensor 21 arranges (preferably arranging) upward towards tray interior and keeps flushing with described internal face 11, for detecting the level pressure in box body 10; Another sensor 22 is arranged at bottom described box body 10, and its be provided with towards box portion outside arrange sensitive surface 24(preferably arrange down), for detecting the level pressure outside box body 10, the sensitive surface 23 of described two sensors 21,22,24 towards the opposite, respectively towards both sides inside and outside box body 10.It is worth mentioning that, the sensitive surface 23,24 of described two sensors 21,22 keeps flushing, and is namely positioned in same level, after so arranging, under same environment, under same testing conditions, can measures the level pressure of both sides inside and outside box body 10 simultaneously.In addition, the bottom of described box body 10 is also provided with a filter screen 12.
It should be noted that, one end of described first water pipe 30 is connected to bottom box body 10, and by the opening and closing realization of an automatic switch 50 and box body 10 inside be communicated with or partition, the other end of described first water pipe 30 is placed in waters, earth's surface 300, and by the opening and closing realization of another automatic switch 50 and being communicated with or partition of waters, earth's surface 300.Described second water pipe 40 is connected on the top cover 13 at described box body 10 top, and is communicated with described box body 10 inside.
When detecting, all water is filled in described box body 10 and described first water pipe 30, after unlatching two automatic switches 50, according to law of connected vessels, water in water in described box body 10, the first water pipe 30 and the water in waters, earth's surface 300, meeting self-control is to identical water level, and finally make the water level in the first water pipe 30 and the second water pipe 40 be maintained at the same horizontal plane, therefore, namely the level pressure value measured by the supine inductor 21 of induction be positioned at bottom box body 10 equals the level pressure value in waters, earth's surface 300.Now, the difference X-Y that described two sensors 21,22 record is the water level difference of surface water and groundwater.In addition, by arranging the time step that sensor 21,22 records, the long-term sequence monitoring of surface and ground water recharge connection can be realized.
In sum, the utility model utilizes law of connected vessels, adopt box body 10 and water pipe 30, the setting of 40, level pressure in box body 10 and earth's surface level pressure are consistent, thus by two sensors 21 bottom box body 10, 22 can detect the level pressure inside and outside box body 10 simultaneously, and the level pressure obtaining surface water and groundwater is poor, whole process more becomes more meticulous and robotization, and the pressure test mode unified surface water and groundwater, the level pressure of surface water and groundwater can be recorded under same environment and condition simultaneously, error is less.
The above; it is only most preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, all belong to the scope of claims protection.
