Description
Technical field
This utility model relates to depth sampler in a kind of subsoil water boring, belongs to hydrogeology, engineer geological prospecting skill
Art field.
Background technology
In hydrogeology, engineer geological prospecting work, it is necessary to obtain groundwater sample, by right by boring or well
The chemical analysis of the groundwater sample obtained understands the physicochemical property of subsoil water；More can pass through in Groundwater Contamination Investigation
Acquired water sample grasps subsoil water contamination situation, and polluting for treating groundwater provides technical basis.
Frequently with sampling bottle, sampling cylinder or the pipe being referred to as " Beile's pipe " time in traditional hydrogeologic prospecting technology
Shape sampler gathers groundwater sample.Owing to common sampling bottle, sampling cylinder belong to opened upper end formula sampling container, when it sinks to
The most just vessel space can be filled with time below the water body water surface, it is impossible to get the water body of selected depth.The water of Beile's cast
Although body sampler water inlet is in bottom, rely on the pearl spheroid in pipe and be arranged on upper and lower be provided with water hole body,
The slip tube core being positioned at pearl spheroid bottom being arranged in body, utilizes the centrally disposed bore of slip tube core and pearl spheroid
Cooperation.When the water body sampler utilizing Beile's cast enters water body from top to bottom, the buoyancy that in well, water body produces holds up and slides
The pearl spheroid of tube core simultaneously jack-up slip die center, makes the current in well enter tube cavity from centre bore, along with
In body, the effect lower slider tube core of water body gravity in pipe that increases of the water yield is returned at the bottom of pipe, and by the reset closure of pearl spheroid
Inlet opening, until filling water body position in tank body.
In recent years according to the above-mentioned water intaking principle of Beile's pipe, occur in that some are similar to the sampling of the subsoil water of piston valve type
Device.
According to the applicant, this class underground water sampler is sampled the analysis of effect, finds that this class subsoil water samples
It is merely able to realize the water sample under conventional hydrogeologic condition.But some upper stratas are had been subjected to the water body that NAPL phase is polluted,
Want to further appreciate that pollutant distribution situation on the vertical plane in polluted water body, or want to obtain contaminated layer with lower layer of water
The when of the physicochemical character of body, open type water intaking bottle, intake pipe that not only tradition uses cannot realize, it is simply that traditional Beile
Pipe or similar piston-type sampler all cannot realize above-mentioned purpose.Its reason is: once these samplers touch ground
During the lower water surface, owing to the water inlet of the backwater effect device for fetching water of water body will be opened, therefore at the continuous sinking watching of sampler
In, the polluted-water (such as greasy dirt etc.) on subsoil water upper strata, tube cavity will be entered together along with the water body entered in body, and
When sampler reaches the depth selection set, fill the most contaminated water body in upper strata in body, may not obtain
Obtain the normal water body of set depth.Obviously, this obtains the work purpose of the true present situation of subsoil water for hope by exploratory bore-hole
For be a kind of defect.
Therefore it provides a kind of applicable ground water fixed depth water sample sampler is not only in hydrogeologic prospecting needs solution
Problem, is also to investigate the problem that subsoil water is badly in need of by the water body actual state after environmental pollution solving.
Utility model content
The purpose of the present utility model: be directed to one and can be applicable to hydrogeology, engineer geological prospecting pollution
Depth sampler in the boring of site investigation subsoil water.
Depth sampler in this boring, including the cylinder 1 that is filled with water, the steel wire rope 7 that hangs on the cylinder top that is filled with water, its feature
It is: the bottom of the described cylinder 1 that is filled with water is made up of the valve body bearing 5 disposing electromagnetic valve 3, the top of the described cylinder 1 that is filled with water
Being covered with one group of unidirectional tapered check-valves 6, described tube filled with water intracoelomic cavity is by the water inlet 4 on bottom electromagnetic valve 3 and top cover
The outer outlet of upper unidirectional tapered check-valves forms bottom water inlet, the fluid reservoir chamber of top aerofluxus；Described electromagnetic valve 3 passes through
Cable 9 obtains and starts power supply, thus constitutes depth sampler in the boring of electrodynamic type subsoil water.
The described ball valve that electromagnetic valve 3 is an electromagnetic start, is connected with controlling power supply by cable.
One end of described steel wire rope 7 is connected to be filled with water on the fixed support of cylinder 1 upper cover, and this steel wire rope upper end is furnished with steel
Cord is soaked and is automatically positioned alarming device 8.
According to depth sampler in this boring that above technical scheme proposes, arrive the sampling of projected depth at sampler
During position, open water inlet by the electromagnetic valve at the bottom of automatically controlled driving cylinder and sample.Taken sample position can not only be fully ensured that
Correctness, and, the guarantee required reliability that obtain lower floor water sample unaffected when penetrating upper strata polluted-water；The suitableeest
It is used for underground water pollution site investigation.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1-is filled with water the cylinder 2-counterweight 3-electromagnetic valve 4-water inlet 5-single-phase tapered check-valves of valve body bearing 6-
7-steel wire rope 8-soaks and is automatically positioned alarming device 9-cable.
Detailed description of the invention
Further describe this utility model below in conjunction with Figure of description, and provide embodiment of the present utility model.
Depth sampler in this boring as shown in Figure 1, it is in currently used multiple groundwater exploration boring
A kind of inventive improvements of water body sampler.
Depth sampler in the boring of this subsoil water, including the cylinder 1 that is filled with water, the steel wire rope 7 that hangs on the cylinder that is filled with water, it is special
Levy and be: the bottom of the described cylinder 1 that is filled with water is made up of the valve body bearing 5 disposing electromagnetic valve 3, the described cylinder 1 that is filled with water
Top cover is provided with one group of unidirectional tapered check-valves 6, and described tube filled with water intracoelomic cavity is by the water inlet 4 on bottom electromagnetic valve 3 and top
The outer outlet covering unidirectional tapered check-valves forms bottom water inlet, the fluid reservoir chamber of top aerofluxus；Described electromagnetic valve 3 leads to
