Abstract
The utility model discloses a vacuum sampling device for a single-hole and multi-layer well. According to the sampling device, a high-power vacuum pump is use for vacuuming to obtain sampling power, the vacuum pump is connected with a sampling bottle in each passage of the single-hole and multi-layer well, each sampling bottle is provided with a water guide pipe with a valve, and all the water guide pipes are connected with the same waste liquid cylinder. With the vacuum sampling device, when the vacuum pump runs, beginning or stopping of sampling of each sampling bottle completely depends on a connecting switch between the vacuum pump and the sampling bottle. Simultaneously, waste liquid can be conveniently emptied by utilizing a switch at the bottom of each sampling bottle. The vacuuming efficiency of the vacuum pump is much higher than the efficiency of a peristaltic pump, thus the time cost for emptying detention waste water is reduced, so that actual working efficiency is improved.
Description
Technical field
The utility model relates to the device technique of a hole multiple zone well sampling, relates in particular to a kind of vacuum sampling device of a hole multiple zone well.
Background technology
One hole multiple zone well refers at same position lays a glance wellhole, and then layering is established well in the Different Strata degree of depth.It is nearly twenty or thirty popular a kind of one-tenth well technology in hydrogeological industry research and production in the world over year.This technology both can be saved the cost of override interrupt, can monitor the same position different depth again.Each hole multiple zone well contains three to seven passages, and the aperture of each passage is generally less than 2cm.At present, in the research and production process, utilize peristaltic pump to sample to a hole multiple zone well, the advantage of peristaltic pump sampling is accurately to control flow, but peristaltic pump is owing to adopting the sampling of drawing water of vacuum principle, so when water level surpassed 10 meters apart from ground, peristaltic pump just can not take out water sample again; The manually-operated of large amount of complex has simultaneously also increased the demand to manpower, also can cause sampling not carry out simultaneously in batches.The drawback of existing peristaltic pump differential force and complicated operation has limited the efficiency of real work greatly.
The utility model content
In order to overcome the existing peristaltic pump that utilizes, realize the problem of sampling process medium power deficiency, inefficiency in batches, the utility model provides a kind of new vacuum sampling device, utilize this device can be under few manually-operated, mass ground carries out quick sampling to all passages of a hole multiple zone well simultaneously.
The utility model adopts a high-power vacuum pump to vacuumize as sampling power, in one each passage of hole multiple zone well, be provided with a probe tube, each probe tube connects respectively a sampling bottle, the top of sampling bottle is provided with is with valvular exhaust tube, all exhaust tubes are connected with vacuum pump, valve can switch, controls beginning that sampling bottle vacuumizes sampling and stops; The bottom of sampling bottle is provided with is with valvular aqueduct, all aqueducts jointly to link a waste liquid cylinder.Valve can switch, controls water sample and stays sampling bottle or flow out sampling bottle in the waste liquid cylinder.
Each passage of the utility model one hole multiple zone well is corresponding to a sampling bottle.Like this, as long as vacuum pump is in operating condition, the beginning of each sampling bottle sampling and the connecting valve that stops depending on fully vacuum pump and sampling bottle.Simultaneously, while due to sampling, starting, to carry out the old water be detained in each passage emptyingly, utilize the switch of each sampling bottle bottom can realize easily the emptying operation to waste liquid.Due to vacuum pump to vacuumize efficiency high more a lot of than the efficiency of peristaltic pump, so the time cost of the old water of emptying delay will reduce, thereby make the efficiency of real work get a promotion.
The beneficial effects of the utility model are, simple to operate, whole process is easily controlled, and the vacuum of sampling apparatus is improved, and work quality and efficiency promote thereupon, can be in the situation that manpower work still less obtain the more sampled result of high-quality.
The accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
1-vacuum pump in figure; The 2-sampling bottle; The 3-probe tube; The 4-exhaust tube; 5-waste liquid cylinder; The port of 6-vacuum pump; 7-waste liquid three-way valve; The 8-pneumatic operated valve; The 9-fixed support; The 10-aqueduct; The 11-sample cock; 12-hole multiple zone well passage.
The specific embodiment
Below in conjunction with accompanying drawing, and by embodiment, the utility model is described in further detail.
With reference to figure 1, one hole multiple zone well contains several passages, each passage connects respectively a sampling bottle 2 by probe tube 3, each sampling bottle 2 is connected to by the exhaust tube 4 with valve 11 on the port 6 of vacuum pump of vacuum pump 1, the bottom of each sampling bottle 2 is provided with the aqueduct 10 with valve 7, and all aqueducts are linked a waste liquid cylinder 5 jointly.Before sampling starts, probe tube 3 is stretched in a hole multiple zone well respective channel 12 that needs sampling, open sample cock switch 11 and waist valve door switch 7.On the sealing rubber ring at the top cover place of waste liquid cylinder 5, coat vaseline, make top cover and sealed bottom good.Connect vacuum pump 1 power supply, start to vacuumize, the water in a hole multiple zone well passage enters sampling bottle 2 along probe tube 3, and then flows into waste liquid cylinder 5.According to sampling request, require at least emptying 2 to 3 times of volumes that are detained old water just can start sampling.After volume of water sample in flowing into the waste liquid cylinder reaches sampling requirement, close waste liquid cylinder valve door 7 and start sampling.Volume of water sample in flowing into sampling bottle reaches the volume required requirement of test, closes sampling pneumatic operated valve 8 and valve switch 11 and gets final product.For a hole multiple zone well of different port numbers, can adopt the sampling bottle device of different tricks.Simultaneously vacuum pump, sampling bottle, waste liquid cylinder and water guide tracheae are fixed on support 9, can facilitate the movement of sampler in sampling process, reduce unnecessary workload.
Finally it should be noted that, the purpose of publicizing and implementing mode is to help further to understand the utility model, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and appended claim, various substitutions and modifications are all possible.Therefore, the utility model should not be limited to the disclosed content of embodiment, and the claimed scope of the utility model is as the criterion with the scope that claims define.
