Background technology
Gap water water sampler is one of instrument of lake and wetland environment and ecosystem research indispensability.During the water sample of prior art different time different depth in gathering sediment, after collector being shifted out the water surface water sample of gathering is analyzed, once more same position is repeatedly sampled as need, then can not guarantee in position and produce error, and consuming time longer, operation inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device of gathering gap water water sample is provided, and is applicable to shallow lake and wetland, but in-situ synchronization is gathered different time, different depth gap water water sample.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of device of gathering gap water water sample, it is characterized in that: set gradually negative pressure equipment, surge flask, dissolved oxygen DO water sample bottle, the water sample bottle, filtrator, valve and sampling pipe, surge flask wherein, the bottleneck of dissolved oxygen DO water sample bottle and water sample bottle is equipped with the sealed rubber gag, be equipped with 2 through holes on the sealed rubber gag, gas outlet first line seal of negative pressure equipment is passed through hole upper end in surge flask of surge flask gag, second pipeline is set, the one end places bottom in the surge flask, another through hole of other end hermetically passing surge flask gag and a through hole of hermetically passing dissolved oxygen DO water sample bottle stopper upper end in dissolved oxygen DO water sample bottle again, the 3rd pipeline is set, the one end places bottom in the dissolved oxygen DO water sample bottle, another through hole of other end hermetically passing dissolved oxygen DO water sample bottle stopper and a through hole of hermetically passing water sample bottle stopper upper end in the water sample bottle again, the 4th pipeline is set, the one end places bottom in the water sample bottle, be communicated with filter outlet behind another through hole of other end hermetically passing water sample bottle stopper, filter inlet is inserted the piston of setting in sampling pipe and the hermetically passing sampling pipe to the sampling pipe bottom after being communicated with the 5th pipeline and valve, be fixed with piston rod on the piston, piston rod protrudes upward the sampling mouth of pipe, a snorkel also is set, snorkel lower end hermetically passing piston, snorkel upwards also stretches out the sampling mouth of pipe, and the sampling tube wall side face between piston and sampling pipe bottom surface is provided with weepage holes.Weepage holes is arranged at the same surface level near the sampling pipe bottom surface, is distributed on sampling tube wall side face.The conical surface is arranged in the sampling pipe bottom surface, and weepage holes place xsect is the awl end, and the vertex of a cone is the sampling pipe bottom.
Advantage of the present utility model and effect:
(1) but in-situ synchronization, obtain a plurality of water samples of shallow lake and wetland different time different depth and different measuring points fast; (2) cost is low, and convenient the making is easy and simple to handle.
Description of drawings
Fig. 1 is a general structure synoptic diagram of the present utility model.
Embodiment
Further specify principle of work of the present utility model and embodiment below in conjunction with accompanying drawing
Referring to Fig. 1, negative pressure equipment 6, surge flask 7, dissolved oxygen DO water sample bottle 8, water sample bottle 9, filtrator 10, valve 11, sampling pipe 12 is by pipeline 1,2,3,4,5 are together in series, be provided with piston 13 in the sampling pipe 12, piston rod 14 protrudes upward the sampling mouth of pipe, also be fixed with snorkel 15 on the piston 13, piston area is passed in snorkel 15 lower ends, the sampling mouth of pipe is also stretched out in the upper end, pipeline 5 one ends are communicated with in the outlet of valve 11, the other end inserts the pistons 13 that are provided with in sampling pipe 12 and the hermetically passing sampling pipe 12 to the sampling pipe bottom (along the conical surface until the vertex of a cone), draw, when pressing piston rod 14 drive pistons 13 to move up and down in sampling pipe 12, snorkel 15 and pipeline 5 be interlock thereupon all.
Before needs are gathered the water sample of 18 times a certain degree of depth in 17 times water and soil interfaces of the water surface (water-bed face) (for example 20 centimeters), earlier piston 13 is pushed into weepage holes 16 and goes up the position slightly, with the top of sampling pipe 12 vertically insert the water and soil interface until weepage holes 16 do not have in the entry and with the vertical height at water and soil interface be 20 centimeters places, water sample infiltrates in the sampling pipes 12 by weepage holes 16.Open valve 11, start negative pressure equipment 6, because pressure difference, water sample can enter in the water sample bottle 9 by pipeline 5, filtrator 10, pipeline 4, when 9 collections of water sample bottle are full, water sample can enter in the dissolved oxygen DO water sample bottle 8 by pipeline 3, when 8 collections of dissolved oxygen DO water sample bottle are full, water sample can enter in the surge flask 7 by pipeline 2, when liquid in the surge flask 7 was 9 two times of left and right sides of water sample bottle, this end of sampling only needed dissolved oxygen DO water sample bottle 8, water sample bottle 9 are taken back lab analysis and got final product, sampling pipe 12 then needn't be extracted from the bottom, has guaranteed the original position of next sampling.
In the foregoing description, sampling pipe 12 lower ends are that conical surface shape is for the ease of inserting benthal deposit and guaranteeing pipeline 5 samplings.Snorkel 15 is set is when moving for piston 13, but supplied gas turnover sampling pipe, and it is consistent with air pressure to keep the sampling pipe inner air pressure in addition when water sampling.Valve 11 is used to blind off a line, and then the progress of water sample is gathered in control.Weepage holes 16 can make sampling pipe 12 outsides seep water faster to inside for a plurality of and the even distribution of one week of edge sampling tube wall, weepage holes 16 be positioned on the same xsect be for the collection result of gathering same degree of depth water sample more accurate, one week of tube wall evenly distributes, so that the water sample of same cross section different azimuth all can enter in the sampling pipe 12.Filtrator 10 (microporous filter) is set sample can directly be measured, reduce follow-up water sample pre-service link.
