Description
Technical field
What the present invention relates to is a kind of water sampling device, in particular a kind of telescopic water sampler.
Background technology
To water body research, observation water quality and variation, be to realize by collection, chemical examination and analysis to water sample at present.According in " water and effluent monitoring analytical approach (the 4th edition) " about the arrangement principle of surface water monitoring site, water sampling will be determined according to water depth.After the depth of water arrives to a certain degree, after gathering the top layer water sample, the position that also needs to determine under water to gather water sample.In addition, in water geology, often to (collect water sample in 5～10cm) inspection chambers, and the water yield be less in the inspection chamber, be difficult for gathering small-bore.
Present synthetic bucket sampler commonly used, its surface scribbles the Teflon, though can be implemented in small-bore inspection chamber or depthkeeping collection water sample, has following deficiency:
1, this sampler does not have the function of sounding the depth of the water, and when gathering a certain degree of depth water sample, needs measure sampled point earlier;
2, this sampler volume is bigger, and length is generally about 1m, is inconvenient to use;
3, the sample volume of this sampler is 160～725mL, device comes draw samples because the employing teflon soars, and it is bigger to be subjected to outside water sample effect of depth, and the inner height of gathering water sample of each sampler can not surpass the outside depth of water, run into more shallow water sample, need repeatedly to gather;
4, in the process that needs the water sample of gathering is shifted after sampling finishes, need say that the sampling thief reversing is from the upper end water outlet, cause water sample to shift easy entrained gas, the interference when causing some index test also may increase the risk of the pollution of sample in this process;
5, it is bigger to gather water surface area, but the more shallow water sample of the depth of water.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of telescopic water sampler is provided, realize the one man operation, accurately gather water sample.
The present invention is achieved by the following technical solutions, the present invention includes collection tube, flexible water storage cavity, supports slide bar, control lever and pull bar; Wherein: the bottom of flexible water storage cavity links to each other with collection tube, the top of flexible water storage cavity is provided with sliding roof, and control lever links to each other with sliding roof, and sliding roof is set in and supports on the slide bar, an end that supports slide bar links to each other with pull bar, and the bottom of the other end and flexible water storage cavity links to each other.
Described sliding roof is provided with draw ring, and control lever and draw ring are fixedly linked, and can maintain easily control lever and sliding roof.
In order when loweing or promoting collector, to realize the measurement to sampling depth, be respectively equipped with scale on described control lever and the pull bar.
Described flexible water storage cavity is seal chamber, and flexible water storage cavity is made by tygon, and is flexible, acid-alkali-corrosive-resisting, and can clean by the store method of water sample, can pollution water sample in the time of sampling.
The bottom of described flexible water storage cavity is provided with the metal disk body, and metal disk body and collection tube are communicated with, and the metal disk body can increase the weight of collector, and keeps it vertical in water, increases the precision that sounds the depth of the water.
The top of described collection tube and metal disk body are communicated with, and the bottom of collection tube is the disk end, and the body of collection tube is provided with the inlet opening.The disk design of collection tube bottom can allow operating personnel's perception collector touch water bottom, reduces measuring error, prevents that also collection tube from inserting water bottom mud, causes the inlet opening to be blocked.
When in the sampling water body excessive impurity being arranged, the inlet opening of described collection tube is provided with screen pack.
The diameter of described collection tube and the ratio of length are 1:10～1:20, and the diameter of collection tube is less, can prevent effectively that water sample from flowing backwards.
The present invention has the following advantages compared to existing technology, the present invention controls the flexible water storage cavity work that is positioned under the water surface by the control lever that operation is positioned on the water surface, can control sampling volume, sampling depth flexibly and accurately can go deep into simultaneously sampling in the less inspection chamber of bore, and sample shifts simple, be not vulnerable to pollute, have characteristics portable, flexible, simple to operate, do not increasing under monitoring personnel's the labour intensity condition, improved precision and the efficient of sampling.
