Background technique
With being constantly progressive for modern science and technology, with being showing improvement or progress day by day for society, the activity of mankind's improving earth is growing more intense, Therefore expedite the emergence of out various technologies with help people understand the earth, by means of drilling be then the common technological means of people it One.First-hand geologic information can be obtained by drilling, formation lithology is understood, obtains THE EARTH INTERIOR PHYSICS information, to sum up, Have become the mankind by drilling technique and understands the indispensable important tool of earth's interior structure.The utility model relates generally to Drill observation of groundwater levels, assists in people and obtains groundwater level depth information, to obtain zonal underground hydrological Data.Traditional measurement method then uses steel tape directly to measure, and this monitoring means has the disadvantage that 1, use condition has Limit, it is shallower to apply in general to groundwater level depth, can direct naked-eye observation, and when depth to water is relatively deep so that naked eyes can not When observation, then it is difficult to be applicable in;2, measurement error is larger, is difficult to ensure when directly being measured using steel tape and just touches the water surface, pole Easily cause reading higher or relatively low.
Therefore, it is necessary to design a kind of strong applicability, drilling underground water level measurement device with high accuracy.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of drilling underground water level measurement devices, not only exist It is also capable of measuring when level of ground water is deeper, and error is smaller, precision is high.
The utility model is in order to solve the above technical problems, used technical solution is: a kind of drilling underground water level measurement Device, the hold-down support including being placed in drilling top, the hold-down support includes upper bracket, intermediate support and undersetting, It is arranged on upper bracket there are two measuring coil, sets that there are two through-holes on intermediate support, on intermediate support between two through-holes Equipped with looping pit, after lightweight filament passes through looping pit, both ends sequentially pass through kickboard respectively, through-hole is connected with measuring coil.
Preferably, two looping pits also are provided in kickboard, lightweight filament is connected by looping pit with kickboard.
Preferably, the looping pit in corresponding measuring coil, through-hole and kickboard is located in same vertical line.
Preferably, the looping pit on intermediate support is set to the midpoint of two through-holes.
Preferably, the internal diameter of the looping pit is slightly larger than the diameter of lightweight filament, and the outer diameter of looping pit is slightly larger than its internal diameter.
Preferably, notch is equipped on undersetting, the both ends of the notch are corresponding with two through-holes.
The utility model has the beneficial effects that
1, applicability is stronger, and no matter level of ground water just, can measure;
2, error is smaller, and precision is higher;
3, structure is simple, easy to operate;
4, cost is relatively low, easy to spread.
Detailed description of the invention
Fig. 1 is a kind of operation schematic diagram of underground water level measurement device that drills;
Fig. 2 is a kind of structural schematic diagram of underground water level measurement device that drills;
Fig. 3 is a kind of measuring principle figure of underground water level measurement device that drills;
In figure, hold-down support 1, upper bracket 1.1, intermediate support 1.2, undersetting 1.3, measuring coil 2, through-hole 3, lightweight are thin Line 4, looping pit 5, kickboard 6.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of drilling underground water level measurement device, the hold-down support including being placed in drilling top 1, the hold-down support 1 include upper bracket 1.1, intermediate support 1.2 and undersetting 1.3, be arranged on upper bracket 1.1 there are two survey Coil 2 is measured, such setting enables measuring coil 2 to rotate on upper bracket 1.1, convenient for measurement.On intermediate support 1.2 If there are two through-holes 3, looping pit 5 is equipped between two through-holes 3 on intermediate support 1.2, after lightweight filament 4 passes through looping pit 5, Both ends sequentially pass through kickboard 6 respectively, through-hole 3 is connected with measuring coil 2, being integrally formed measuring device, kickboard 6 in the present embodiment Using round kickboard.
Preferably, two looping pits 5 also are provided in kickboard 6, lightweight filament 4 is connected by looping pit 5 with kickboard 6.This The setting of sample, and can be free to slide in looping pit 5 so that lightweight filament 4 can not only connect kickboard 6, when kickboard 6 by When gravity moves downward, lightweight filament 4 will not impact the decline of kickboard 6.
Preferably, the looping pit 5 in corresponding measuring coil 2, through-hole 3 and kickboard 6 is located in same vertical line.It is such Setting is convenient for measurement and calculates.
Preferably, the looping pit 5 on intermediate support 1.2 is set to the midpoint of two through-holes 3.Such setting increases The stability that kickboard 6 declines, reduces error, improves measurement accuracy.
Preferably, the internal diameter of the looping pit 5 is slightly larger than the diameter of lightweight filament 4, and the outer diameter of looping pit 5 is bigger in the inner Diameter.Such setting does not interfere with measurement result so that the size of looping pit 5 can be ignored.
Preferably, notch is equipped on undersetting 1.3, the both ends of the notch are corresponding with two through-holes 3.It is such to set It sets so that lightweight filament 4 after through-hole 3 in notch by that can hang to kickboard 6, undersetting 1.3 has not only acted as supporting role, And it will not influence the decline of kickboard 6.
The present embodiment working principle is as follows: measuring Shi Yingxian and nearby carries out levelling of the land to drilling orifice, and will consolidate Determine support 1 and be placed in drilling top, prevents from causing error in reading since measuring instrument tilts.Kickboard 6 under Gravitative Loads from By landing, measuring coil 2 is drawn by the transmission effect of lightweight filament 4 and is rotated, until contacting underground water level.
The looping pit 5 on looping pit 5 and kickboard 6 on through-hole 3, intermediate support 1.2 forms triangle by lightweight filament 4 Shape, the horizontal plane where undersetting 1.3 intersect with plane where triangle, have a line in triangle, pass through similarity relation Groundwater level depth can be acquired.
The distance for measuring looping pit 5 on a through-hole 3 to intermediate support 1.2 is X, intermediate support 1.2 and undersetting 1.3 it Between distance be Y.Measuring scale is placed on the horizontal plane at 1.3 place of undersetting, reading distance in triangle is Z.Meter is round For kickboard with a thickness of D, round kickboard self weight is G, and the density of water is ρ, and local acceleration of gravity is g, then groundwater level depth H= (Y × Z)/(X-Z)+D- G/ (ρ × g), only Z is unknown quantity in formula, and when measurement only can need to accurately find out underground by measuring Z The buried depth of water level.
Not only applicability is stronger for the present embodiment, and no matter level of ground water height can measure, and error is smaller, precision compared with Height, while structure is simple, easy to operate, cost is relatively low, easy to spread.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the features in the embodiments and the embodiments of the present application in the absence of conflict, can mutual any combination.This is practical new The protection scope of type should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also the protection scope of the utility model it It is interior.
