Description
Technical field
The utility model is related to hydrologic monitoring technical field, specifically a kind of dress measuring underground water lowest water level
It sets.
Background technology
Underground water is the important resource of water supply in many cities of important component and the northern area of China of water resource,
These regional underground water in for water inventory proportion often beyond 50%, some cities can even be up to 80% with
On, therefore the rational exploitation and utilization of underground water has the socio-economic development and improvement of the ecological environment of China's especially northern area
There is highly important effect.In recent decades, with the continuous development of China's economic society, groundwater resources yield increasingly increases
Add, underground water pollution aggravates, and makes rational planning for due to lacking and effectively supervises, is allowed to produce and regionally descends water level decreasing, water
A series of exhausted, and then the ecologies such as induce surface subsidence, ground fissure, seawater invasion, the soil salinization and desertification of land in source ground
And the problems of geo-environment, these problems directly affect the sustainable use of groundwater resources, also restrict the complete of economic society
Face, harmonious and sustainable development.Therefore, it is necessary to formulate and implement the related management and Conservation strategies of groundwater resources.
The reasonable implementation of Groundwater Resource Management and Conservation strategies is needed to the benefit diameter row of local ground watering and migration rule
It is fully understood, and underground water lowest water level is then one of important elements.Such as in the inaccurate minimum water of underground water
Position measurement data in the case of carry out groundwater resources development, often due to the increase of hydraulic gradient pollute it is further
The serious consequences such as deterioration, surface subsidence and saline Land.Therefore how efficiently and accurately, simply save to the minimum water of underground water
Position, which measures, just becomes particularly important.Traditional survey clock method is only applicable to no closed motor-pumped well since the visual field limits；It is double to lead
Line conductive method forms current loop when being contacted with the water surface, will be shown on universal meter by the way that two conducting wires are put into well
Show reading.Such method conducting wire is when being put into well, it is easy to hang water on the borehole wall or metal well casing contacts, be formed into a loop, make
At error；Electric lead is easy to happen bending in measurement process simultaneously, will also result in error.Utility model
CN201620339799.1 draws tape measure by weight, though and it sticks changeable colour test paper in tape measure bottom end and can solve above-mentioned ask
Topic, but as above two method, maximum drawback be due to underground water lowest water level need to carry out long-term observation it is (several
- one year a month) it can obtain, therefore special messenger need to be arranged frequently to be measured to measurement point, cause a large amount of manpower and materials to lose.
Further for some it is other can with the advanced measuring instrument and method of real-time Transmission measurement data, as supercritical ultrasonics technology,
Laser infrared collimation method and resistivity scaling method, it is expensive, electric drive is needed, is not easy to organize work in the wild, increases survey
The difficulty and cost of amount；If no special messenger keeps an eye on, instrument is easily lost, and causes economic loss, and the measurement of such method
Precision is not often high (such as laser method range error often reaches 0.5m).
So the problem of lowest water level detection difficult to underground water exists in the prior art.
Utility model content

Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work, all
Belong to the range of the utility model protection.
As shown in Figure 1 to Figure 3, the utility model includes fixed plate 1, reel 2, nylon wire 3 and floating 4.2 turns of reel
Dynamic to be connected in fixed plate 1, on reel 2, the other end of nylon wire 3 ties up in floating 4 one ends wound of nylon wire 3.Drift
Floating 4 be in coniform, and nylon wire stretchy reel 2 rotates when the pulling force of nylon wire 3 is not less than the gravity of floating 4, when
The pulling force of nylon wire 3 is less than static around 2 opposing fixed plate 1 of reel when the gravity of floating 4.
As shown in Figure 1 to Figure 3, when monitoring level of ground water using the utility model, floating is placed into water first
In literary geology well so that floating 4 floats on the water surface of hydrogeological well, and fixed plate 1 is fixed on hydrogeological well after allowing
At pithead position, reel 2 is then rotated manually, reel 2 is made to carry out coiling work to nylon wire 3, until nylon wire 3 is made to exist
It is just exceptionally straight under the gravity of floating.At this point, if first reel 2, which is fixed in fixed plate, (namely prevents reel from sending out
Raw rotation), then fixed plate 1 is removed from the well head of hydrogeological well again, then floating 4 is taken out from hydrogeological well,
The height of level of ground water at this time can be extrapolated by measuring the unwrapping wire length of nylon wire 3 at this time, so, the utility model has
Measure the technique effect of level of ground water.
In addition to above-mentioned technique effect, the utility model can also measure the most low land of the underground water within a period of time
Lower water level.For example, it is desired to when minimum level of ground water within this period of time of measuring A to time B, monitoring personnel
The utility model is placed in hydrogeological well in the manner described above when time A first, and nylon wire 3 is made to be in lucky
Then exceptionally straight state makes the utility model be placed in hydrogeological well to time B.If the period in time A to time B
Interior, water level has the case where decline to occur, then just will appear nylon wire 3 pulling force be equal to even be more than floating 4 dead weight (when
When having water in floating), nylon wire 3 carries out the work of unwrapping wire from reel 2 at this time, if in time A to B, water level decreasing
Rise again later, then floating 4 is swum on the water surface after rising due to water level, so, the pulling force of nylon wire 3 is less than floating
Dead weight, reel 2 and without setting-out work at this time.So over time, become, by measuring nylon wire 3 in the hydrology
Profit margin in geology well (pulls nylon wire 3 to make the nylon pulled when nylon wire 3 is just exceptionally straight in the upper end of hydrogeological well
The length of line), you can the maximum value for obtaining the water level decreasing in time A to time B, so as to extrapolate in this period
