Abstract
The utility model provides a monitoring device for the flow speed and current direction of the shallow underground water and consists mainly of a barrel, a collector and probes. The wall of the barrel is provided with holes and the surface of the barrel is wrapped with a gauze mesh. The collector is connected with various probes through conducting wires. The utility model can automatically collect the changing data of the conductivity of the underground water continuously timely and on line in order to relievethe labor load of processing the current measurement results, and plays roles of finding out the dynamic states of the flow speed and current direction of the underground water in the tested regions so as to reasonably exploit the underground water and to monitor the underground water pollution.
Description
Technical field
The utility model relates to a kind of shallow ground water flow rate and direction monitoring device.
Background technology
In low-lying easy waterlogging, impeded drainage, saline-alkali soil area, underground water situation and Changing Pattern thereof directly affect the genesis and development and the fertility state of soil.In order to improve the soil, set up the high and stable yields farmland, must find out the dynamic and Changing Pattern of groundwater velocity and direction.Direction of groundwater flow and the flow velocity method commonly used of measuring has water level contour map method, colourimetry.The water level contour map method measuring the area if any the water level isogram, can be tried to achieve direction of groundwater flow and flow velocity according to perpendicular to water level isoline deviational survey direction.If there is not the groundwater level isogram, to bore three borings (or test pits, inspection well) at least desiring the geodetic district, boring should be arranged on the average 100 meters triangle form point of the length of side.The place, aperture need measure absolute altitude, measures underground water table, calculates underground water table absolute altitude in each boring, and (decide according to underground water gradient size, generally can adopt 10-50cm, little as the gradient spy, spacing should be littler) draws groundwater contour figure at a certain distance.Colourimetry is to drop into colorant according to dropping in the observation boring, in the observation boring that four corners of the world direction is arranged, every the certain hour water sampling, colorimetric on the fluorescence tintmeter, usually have only that underground water just can be coloured in the boring of Parallel to the flow direction,, on coordinate paper, make curve map according to recording the result, horizontal ordinate is sample time, and ordinate is the water sample colorant concentration.At last, from throw in colorant begin up to observation boring the required t of advancing of the painted Cmax of water sample and centre-drilling hole to observation boring apart from s, obtain groundwater velocity v.From above-described two kinds of measurement methods, measurement result all needs artificial treatment, and is time-consuming, and labor capacity is big, secondly can not the phreatic dynamic change of on-line automatic collection.
The purpose of this utility model aims to provide a kind of shallow ground water flow rate and direction monitoring device.Utilize boring and around the probe buried underground, and connects with Acquisition Instrument, then electrolyte is poured in the centre-drilling hole tube, Acquisition Instrument picks up counting and gathers 16 conductivity of popping one's head in the orientation around the center pit automatically, gathers at regular intervals 1 time.Electrolyte touches probe along the infiltration direction of current, and conductivity also increases gradually, the just phreatic as can be known flow direction, again by centre-drilling hole to the time that the distance of popping one's head in and electrolyte touch probe, just can calculate phreatic flow velocity.Meanwhile, store collection result in the Acquisition Instrument, result treatment is become the underground water curve map by computing machine.
The purpose of this utility model can realize by following measure
A kind of shallow ground water flow rate and direction monitoring device is made up of tube, Acquisition Instrument, probe, and the infiltration water hole is arranged on the barrel, the outer wrapping gauze, and Acquisition Instrument is connected with each probe by lead.
The beneficial effect of advantage of the present utility model and generation is
1, equipment is simple, and is easy to operate.Around center pit, drill and bury probe underground, electrolyte in pouring the centre-drilling hole tube into touches the probe in certain orientation along groundwater flow infiltration sandy soil, conductivity increases, just the direction of groundwater flow as can be known, secondly by the time of centre-drilling hole to distance between probe and Acquisition Instrument record, just can measure phreatic flow velocity, thereby realize the purpose of this utility model.
2, on-line automatic image data regularly understands that to grasp groundwater flow dynamic, alleviates artificial labor service, draws accurate and real-time Monitoring Data, for tested regional groundwater flow dynamically provides scientific basis.
3, the utility model helps findding out tested regional groundwater dynamic and Changing Pattern thereof, for rational exploitation underground water, monitoring groundwater contamination, protection groundwater resource, promotes that regional economy continues, stable development will produce certain positive role.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail again
A kind of shallow ground water flow rate and direction monitoring device is made up of tube 1, Acquisition Instrument 3, probe 4, and infiltration water hole 2 is arranged on tube 1 wall, the outer wrapping gauze, and Acquisition Instrument 3 is connected with each probe 4 by lead 5.
Desiring centre-drilling hole of geodetic district brill, the tube 1 of wrapping up in gauze is outward directly put into, go deep into shallow ground water 2-3 rice.Around centre-drilling hole, drill, bury probe 4 two circles underground, 16 probes of every circle, the distance that center pit encloses hole and the 2nd observation circle hole apart from the 1st observation is 0.5-2m, pitch enlargement between the observation port, the soil permeability coefficient is big.Before throwing in electrolyte, utilize Acquisition Instrument 3 to measure the natural conductivity of each boring monitoring point probe 4 all around earlier.Then the solid salt of electrolyte 0.5-1.0kg is poured in the tube 1 of centre-drilling hole, groundwater flow sees through cinclides 2, permeates to sandy soil gradually.Acquisition Instrument 3 picks up counting and gathers the conductivity of 16 probes 4 automatically.Gather 1 time every 5 seconds.When electrolyte dissolves in water, and permeate along the groundwater flow direction, touch the probe in certain orientation, because electrolytical effect, the conductivity of phreatic water (flow) direction begins to increase gradually, can measure the direction of underground water table like this, and touch probe time of 4 by center pit to the distance of probe and seepage electrolyte and just can obtain phreatic flow velocity.Stored data from the storage card of Acquisition Instrument 3 is appeared before one's eyes out the groundwater velocity and direction dynamic change by computing machine at last with curve map.Researchist and hydrlolgic work personnel analyze and research to the result according to the data of being gathered.
