Embodiment
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1-2, piston type underground water sampler, comprise stopple coupon 1 and sampling cock 2, the top of stopple coupon 1 is airtight by upper cover 3, the bottom of stopple coupon is airtight by lower cover 4, sampling cock 2 is located in the middle part of stopple coupon and stopple coupon is divided into upper and lower two cavitys, upper cover and lower cover are all threaded with sampler, and cushioning O-ring seal between, sampling cock does not directly contact with the inwall of sampler, but by O-ring seal and sampler inwall clearance fit, so both can ensure that sampling cock moved up and down smoothly in sampler, sealing function can be played well again, upper plenum is work gas chamber 5, lower cavity is water sample chamber 6, the first spring 8 is provided with in work gas chamber 5, the second spring 9 is provided with in water sample chamber 6, the two ends of the first spring 8 offset with the end face center of sampling cock 2 and the bottom center of upper cover 3 respectively, the two ends of the second spring 9 offset with the bottom center of sampling cock and the end face center of lower cover 4 respectively, form force-closed, the center of sampling cock 2 has the first through hole, the first retaining valve 10 is installed in first through hole, be communicated with water sample chamber and work gas chamber, directly weld between first retaining valve with the first through hole or reached by cushioning O-ring seal and be fixedly mounted with sealing effectiveness, the center of lower cover 4 has the second through hole, the second retaining valve 11 is installed in second through hole, be communicated with extraneous underground water and water sample chamber, directly weld between second retaining valve with the second through hole or reached by cushioning O-ring seal and be fixedly mounted with sealing effectiveness, the center of upper cover 3 has apopore, rising pipe 12 is inserted in apopore, the bottom of rising pipe 12 is connected with one end of flexible pipe 7, the top of rising pipe is connected with sampling container, the other end of flexible pipe is connected with the outlet of the first retaining valve 10, above covers and also has air admission hole, inserts draft tube 13 in air admission hole, draft tube 13 is connected with high-pressure pump 14, and gases at high pressure enter work gas chamber 5 by this hole, one end that first retaining valve 10 contacts with work gas chamber 5 is additionally stretched out, and is conveniently connected with flexible pipe 7, sampling container is beaker 15, and underground water sample is collected in the below that the top mouth of pipe of rising pipe 12 is located at by beaker 15.
As shown in Figure 2, equilibrium state when sampler does not work.In order to prevent influencing each other between different water cut layer, needed to open high-pressure pump 14 before sampler target approach water layer always, and make air pressure increase gradually or maintain maximal value always, sampling cock 2 is made to be displaced downwardly to position, lower pole, the volume of water sample chamber 6 is kept to zero or close to zero, now, the second spring 9 in water sample chamber is in compressive state, the first spring 8 in work gas chamber 5 is in extended state, sampler reaches equilibrium state, like this, sampler through non-targeted water layer time because water sample chamber cannot enter sampler without volume.
As shown in Figure 3, the equilibrium state after sampler target approach water layer a period of time.When after sampler target approach water layer, close high-pressure pump 14, the air pressure of work gas chamber 5 is reduced gradually, above-mentioned equilibrium state is broken, first spring 8 of work gas chamber is supplied to sampling cock 2 one and closes pulling force, the second spring 9 in water sample chamber 6 is supplied to sampling cock one and closes thrust, simultaneously, the hydrostatic force of underground water is also supplied to the effect of sampling cock one thrust upwards, like this, under the acting in conjunction of these power, sampling cock slowly on move, move along with on sampling cock, the volume of water sample chamber slowly increases, underground water also just enters water sample chamber via the first retaining valve 10.Till this process can last till always sampling cock 2 moves to position, pole, now, the second spring 9 is in extended state, and the first spring 8 is in compressive state, and sampler reaches new equilibrium state.
As shown in Figure 4, the equilibrium state after sampler injection gases at high pressure.After reaching the new equilibrium state shown in Fig. 3, open high-pressure pump 14, gases at high pressure are injected to work gas chamber 5 by draft tube 13, the air pressure of work gas chamber is increased gradually, above-mentioned new equilibrium state is broken, first spring 8 is supplied to sampling cock 2 one and closes thrust, second spring 9 is supplied to sampling cock one and closes pulling force, simultaneously, gases at high pressure are also supplied to the effect of a sampling cock downward thrust, like this, under the acting in conjunction of these power, sampling cock slowly moves down, along with moving down of sampling cock, the volume of water sample chamber slowly reduces, and the water of savings in water sample chamber is owing to being subject to the blocking effect of the second retaining valve 11, water table cannot be flowed back to, can only flow in the flexible pipe 7 in work gas chamber by the first retaining valve 10 on sampling cock, first retaining valve also only allows water to flow to flexible pipe 7 not allow water to flow out, till this process can last till that sampling cock is displaced downwardly to position, lower pole always, now, second spring is in compressive state, first is in extended state, sampler reaches initial equilibrium state again.
So far, sampling process completes a circulation, interruption to sampler inject gases at high pressure, underground water just can constantly be drawn to flexible pipe 7, then arrives the beaker 15 on ground via rising pipe 12.
