Background technology

From present lot of documents report limit, doing a lot of work aspect the water pollution monitoring complete set technology both at home and abroad, but more be to lay particular emphasis on the research that analytical approach and standard are chosen the aspect, precision of analysis is played the research of the method for sampling of no less important effect and sampling thief then obviously not as the former hot topic.People such as the Shi Changli of China have designed a kind of long-pending dark formula sampling thief, sampling thief is foraminate vial in bottom or plastic bottle, bottleneck is connected with emulsion tube (being furnished with spring water stopper), during sampling, open tongs earlier, during dried up body bottom 0.5m, adopt the water yield and meet the requirements at the bottom of rate of sinking is adjusted to bottle, adopted sample after, sebific duct is stuck, propose sampling thief rapidly, and be inverted as early as possible and open tongs, change over to water sample in the analyzing container immediately, be not difficult to find out from the structure and the sampling operation of above-mentioned sampling thief, this method of sampling and sampling thief thereof are not only operated very trouble, and have obviously destroyed water body hydrology state at that time, make the water sample distortion.Chinese patent CN1051623A discloses a kind of sampling thief, earlier the bottle bottom is taken off during this sampling, move down draw-in bar then, bottle end liner lid immersed in the water, treat that the water surface is stable after, move down outer tube rapidly to water, on carry draw-in bar, screw holding screw, pick up sampling thief, screw on a bottle bottom, at last sample is changed in certain container.This sample mode and sampling thief are in the havoc that has overcome to a certain degree water body hydrology state, but operation is still very inconvenient.CN2077543U has also done research to water sampler, also still has a lot of shortcoming and defect, though the former has adopted the bottom opening formula, but the water inlet diameter is very little, i.e. 3cm, and water container diameter 9.5cm, changed water body hydrology state when clearly sampling, made the water sample distortion.And latter's sampling thief structure is comparatively simple, but the still distortion because water body hydrology state is destroyed of when sampling sample, and the sampling thief material of main part to choose plastics also improper.

A kind of integration type sampling thief that external rugged fragrant U.S.A of plum that Japan is arranged develops, the method of sampling is with the sampling thief bottom of submerging, when transfering to stopper, up at the uniform velocity mention then with certain speed, to gather the holostrome water sample, though this sampling thief can be gathered the holostrome water sample of certain depth, but still there is the fundamental drawback of destroying hydrology state when sampling and making the water sample distortion.

Summary of the invention

Technical matters: the purpose of this utility model is in order to guarantee the quality of environmental monitoring, overcome the deficiency of above-mentioned sampling thief and propose a kind of novel simple in structure, easy to carry, solid and reliable, replace conveniently, applied widely, can be to surface water, sewage draining exits etc. make things convenient for the environment monitoring instrument of sampling.

Technical scheme: will gather the water sample of different levels during the sampling thief sampling, do not destroy water body hydrology state simultaneously as far as possible, guarantee the representativeness and the objectivity of water sample, by the glass bottle, base, backstay, press rods, screen pack, spring, composition such as handle and pressure handle, adopt the no end hard glass bottle (4) of band scale to be fixed in the middle of the aluminium chassis (5), both contact portions are dug the circular trough of 5～6mm on base, embed O type rubber seal, when preventing to sample under hydraulic action water sample exosmose, base top and backstay (9) are fixed together, be fixed on the handle (1) by the nut that is provided with on one side, its another side is unfixing, the bottom is equipped with ring stainless steel chassis (8), the chassis is supported by stage clip (7), and chassis (5) are pressed on bottle (4), and base is borrowed the pressure of stage clip, force the O-ring seal distortion on the chassis, thereby reach the purpose that sampling back water sample does not leak.

According to choosing of the material of sampling thief being required and easy to process, adopt the Pyrex bulb of the no end of being with scale, be the sampling thief main body that is filled with water, it highly is about 20cm, and internal diameter is 10cm.Change in order to reduce tested water body hydrology state as far as possible, this sampling thief adopts the bottom water intake mode.

Technique effect: the utlity model has following characteristics:

1, this sampling thief can be gathered the water sample of different levels;

2, the utility model is simple in structure, and is easy to carry, solid and reliable, replaces conveniently, and wide accommodation can make things convenient for sampling to surface water, sewage draining exit etc.Overcome the weakness of many existing sampling thiefs;

3, this sampling thief precision meets the requirements, and no matter sampling thief is that precision or concentration value aspect are all better than bailer, science and more credible more, the trouble of having avoided the human factor of instruments such as bailer to bring in the arbitration monitoring;

4, sampling thief can position quantitative sampling.
