Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described.
Referring to Fig. 1, underground water sampler of the present utility model comprises sampling pipe 8, the first gasbag plugs 5 and the second gasbag plug 5
/, be separately positioned on two ports of sampling pipe 8; But the air bag 6 of inflation/deflation, be arranged on the first gasbag plug 5 and the second gasbag plug 5
/between; And the first non-return valve 4, run through the first gasbag plug 5 and the second gasbag plug 5
/in any, be communicated with the first gasbag plug 5 and the second gasbag plug 5
/between space and the first gasbag plug 5 and the second gasbag plug 5
/outside space.
The first and second gasbag plugs 5 and 5
/between space be the space I, the first and second gasbag plugs 5 and 5
/outside space be the space II, wherein the space I is the first and second gasbag plugs 5 and 5
/between do not comprise the space of air bag 6 and sampling pipe 8.The first and second gasbag plugs 5 and 5
/in any on be provided with the first non-return valve 4, it runs through the gasbag plug of set position, thus when this valve is opened connected space I and space II.Air bag 6 is arranged on the first and second gasbag plugs 5 and 5
/between.
By above-mentioned underground water sampler, by air bag 6 inflations, the underground water existed between the first and second air bags, by non-return valve 4, discharged, air bag 6 is again deflatable, therefore, after air bag 6 venting, underground water can infiltrate through the space between the first and second air bags, so that already present water between two air bags is replaced as to fresh water, realizes the displacement to underground water.
As shown in Figure 1, air bag 6 arranges around sampling pipe 8, but should be appreciated that air bag 6 can be around sampling pipe 8, within this arrangement is included in scope of the present utility model equally.Preferably, air bag 6 is structure as a whole, but should be appreciated that it can also be comprised of a plurality of separation or connected utricule, and for example utricule 6 can be comprised of a plurality of flap utricules.
In use procedure of the present utility model, at first, to sampling pipe 8 inflations, make in sampling pipe 8 and possess certain pressure, then it is transferred to floral tube position in monitor well, wherein, to sampling pipe, 8 inflations are in order to guarantee that it is in decentralization process, and the water in floral tube can not enter sampling pipe.When sampling pipe 8 is transferred to desired depth, stop transferring operation, and to the first and second gasbag plugs 5 and 5
/inflation, until they form sealing with floral tube, thereby completely cut off water and the water in the II of space in the I of space.Then, as shown in Figure 3, stop the first and second gasbag plugs 5 and 5
/inflate and air bag 6 is inflated, thereby make the water in the I of space slowly be disposed to the space II by the first non-return valve 4, preferably, air bag 6 should at least be full of 60% of space I after inflation.After elapsed time t1, as shown in Figure 4, stop inflation and to air bag 6 venting, under the effect of pressure differential, from the fresh water sample inflow space I on stratum on every side.After elapsed time t2, to sampling pipe 8 venting, thereby make fresh water sample flow into sampling pipe 8.After elapsed time t3, to the first and second gasbag plugs 5 and 5
/venting, remove the first and second gasbag plugs 5 and 5
/and the sealing between floral tube, make it possible to sampling thief is promoted to well head, thereby the sampling process of completing.Therefore, fresh water sample can be collected in sampling pipe, make the water sample collected more representative, thereby accurately reflect rapidly the interim slight change of quality of groundwater.Should be appreciated that time t1, t2 and t3 should determine according to different groundwater flow flow velocitys, monitor well structure and hydrogeological condition.
Take above-mentioned use procedure as example, and preferred the first non-return valve 4 runs through one top in the first and second gasbag plugs, and wherein, definition upper-lower position relation is identical with the vertical direction orientation.That is, when sampling pipe 8 is transferred to desired depth, a gasbag plug from the well head of monitor well close to more.
In addition, as shown in Figure 2, underground water sampler of the present utility model also comprises that the first wireway 1, the second wireway 2 and the 3rd wireway 3, the first wireways 1 are communicated with sampling pipe 8, the second wireways 2 and are communicated with the first and second gasbag plugs 5 and 5
/, the 3rd wireway 3 communicated air bags 6, thereby in the above-mentioned use procedure of sampling thief respectively to sampling pipe 8, the first and second gasbag plugs 5 and 5
/and air bag 6 inflations.Should be appreciated that, for realizing above-mentioned annexation, the first wireway 1 and the 3rd wireway 3 should run through the first and second gasbag plugs 5 and 5
/in one and realize sealed engagement with this gasbag plug, thereby can be sampling pipe 8 and air bag 6 inflations, and realize that in sampling process sealing is to guarantee that the water of discharging can be from this joint inflow space I.Also should expect, the discharge control valve (not shown) can be set on wireway, thereby can stop inflating to wireway.Preferably, the first wireway and the 3rd wireway run through the first gasbag plug and are communicated with sampling pipe and air bag, the junction surface sealing of the first wireway and the 3rd wireway and the first gasbag plug.Here the first gasbag plug is defined as one top in two gasbag plugs, identical with above-mentioned definition to upper and lower definition.
In addition, the second non-return valve 7 can also be set on sampling pipe 8, its setting position does not hinder the inflation/deflation process of air bag 6.After to sampling pipe 8 venting, under the effect poor at the external and internal pressure of sampling pipe 8 of fresh water sample, by the second non-return valve 7 influent streams, enter sampling pipe 8.
In addition, for realizing in sampling process, sampling thief being located, seal sampling pipe, the two-port of sampling pipe is respectively arranged with the first and second gasbag plugs 5 and 5 simultaneously
/.Further, the first and second gasbag plugs 5 and 5
/removably be fixedly attached to the port of sampling pipe, and the opposite end cause for gossip now seals to guarantee the smooth realization of drainage procedure, guarantee that the water that sampling pipe 8 collects can not spill simultaneously.Preferably, in the first and second gasbag plugs 5 and 5
/on the rigid thread part is set, the threaded engagement of the port of itself and sampling pipe, thus realize sealed engagement.This connected mode is convenient to install and part replacement, so usability is more excellent.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
