Description
Technical field
The utility model belongs to geologic prospect field, is related to a kind of water sample acquisition device more particularly to a kind of pressure control
Formula water sample acquisition device.
Background technology
A most important part is Hydrogeologic Survey in geologic prospect, carries out usually requiring to gather during Hydrogeologic Survey
Water sample especially carries out water sampling to the water body of certain depth in stratum, studies its constituent, content, assesses water body matter
Amount to study Soil water interactions, infers that earth formation provides data reference.The water sample acquisition device of current most of uses,
It is excessively high there are cost, it is impossible to which that the problem of ensureing the quality of water sample or being unable to quantitative collection, being badly in need of one kind now can quantify
Water sample is gathered, ensures water sample quality, the water sample acquisition device being simple and efficient.
Utility model content
In view of problem existing in the prior art, the utility model provide one kind and are simple and efficient, can quantitative collection water sample, protect
Demonstrate,prove water sample quality, the Pneumatic control type water sample acquisition device being simple and efficient.
The technical solution of the utility model is realized by following mode：
A kind of Pneumatic control type water sample acquisition device, including storage room, traction rope, conduit and control terminal, the one of storage room
End is equipped with water inlet, and traction rope is connected with the outer wall of storage room waist, and conduit is connected with storage room, and control terminal includes gas
Flowmeter and valve, conduit upper end are connected with gas flowmeter, and gas flowmeter upper end is connected with valve, when the valve is open,
Conduit is communicated with air, and gas can discharge, when the valve is closed, conduit and atmospheric isolation from conduit.
Storage room is round metal tubular construction, and the gravitation energy of storage room overcomes the buoyancy of water, the outer wall of storage room waist
Hollow metal ring is equipped with, traction rope is lain on hollow metal ring.
Water inlet is arranged on the end of the storage room one side opposite with hollow metal ring.
Traction rope is equipped with scale.
Conduit is made of high intensity, good toughness and corrosion resistant PVC material, and conduit is bolted with storage room.
Gas flowmeter and valve are arranged at earth's surface.
Compared with prior art, the utility model has the advantages that：
（1）The utility model uses the opening and closing state of pressure control water sample acquisition device, and storage room passes through conduit
It is connected with valve, when gathering water sample, closes valve, conduit and atmospheric isolation, storage room submerged under the effect of gravity, due to
Air is difficult to compress, so in storage room sinking watching, water can not be entered by water inlet in storage room, when storage room is sunk
To after designated depth, valve is opened, conduit communicates with air, and under water pressure, the air in storage room is discharged, and water is from water inlet
Mouth after the completion of sampling, closes valve, in storage room uphill process, water can not be again introduced into storage room into storage room.Cause
This, entire water sampling process is not only easy to operate, quickness and high efficiency, and ensure that the quality of taken certain depth water sample.
（2）It,, can be right to reflect storage room inflow by the gas flow in sampling process using gas flowmeter
Water sample carries out quantitative collection, controls the sampling time, makes research process more efficient rationally.
（3）Traction rope is equipped with scale, can accurately control sampling depth.
Description of the drawings
Fig. 1 is the structure diagram of the Pneumatic control type water sample acquisition device of the utility model.
In figure, 1 is storage room, and 2 be water inlet, and 3 be traction rope, and 4 be conduit, and 5 be gas flowmeter, and 6 be valve, and 7 are
Hollow metal ring, 8 be bolt.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, a kind of Pneumatic control type water sample acquisition device, including traction rope 3, storage room 1, conduit 4, control
End, control terminal include gas flowmeter 5, valve 6；Wherein 1 upper end of storage room is connected with traction rope 3 by hollow metal ring 7, storage
It deposits room 1 to be connected by bolt 8 with conduit 4,4 upper end of conduit is connected with gas flowmeter 5,5 upper end of gas flowmeter and 6 phase of valve
Even, when valve 6 is opened, conduit 4 is communicated with air, and gas can be discharged from conduit 4, when valve 6 is closed, conduit 4 and greatly
Air bound is exhausted.
The storage room 1 is columnar structured made of the larger metal of density.
The conduit 4 is by intensity and toughness is preferable, corrosion-resistant material is made.
The traction rope 3 has scale.
The operation principle of the utility model is：
Close valve 6, conduit 4 and atmospheric isolation, the gas in conduit 4 cannot be introduced into air, storage room 1 by density compared with
Big metal material is made, the submerged under the effect of gravity of storage room 1, since air is difficult to compress, so under storage room 1
During heavy, water can not be entered by water inlet 2 in storage room 1, and it is predetermined to learn that storage room 1 is sunk to by 3 scale of traction rope
After depth, valve 6 is opened, conduit 4 is communicated with air, and under water pressure, the air in storage room 1 is discharged into greatly by conduit 4
In compression ring border, gas flowmeter 5 records discharged gas volume, and water enters storage room 1 from water inlet 2, and water sample reaches predetermined
After volume, valve 6 is closed, stops water intaking, promotes traction rope 3, at this time conduit 4 and atmospheric isolation, gas can not continue in conduit 4
Discharge, water can not be again introduced into storage room 1, storage room 1 left the water, and water sampling is completed.Entire water sampling process, both
It ensure that quantitative collection water sample, and ensure the quality of institute's water sampling.
Wherein, control terminal includes gas flowmeter 5 and valve 6 and is arranged on earth's surface, the amount and matter to water sampling process into
Row precise and high efficiency controls.
The above is only the preferable specific embodiment of utility model, but the scope of protection of the utility model is not limited to
In this, in the technical scope that any one skilled in the art discloses in the utility model, according to utility model
Technical solution and its design are subject to replace or change on an equal basis, should be covered within the scope of the utility model.
