Abstract

The utility model discloses an aqueous sample collector comprising a hand-held shank and an upright shank which are bended and connected with each other. Scale marks are arranged on the surface of the upright shrank; sampling bottles, at least one, are vertically arranged on the upright shrank at equal intervals; each sampling bottle corresponds to an air exhaust pipe and a water intake pipe; one end of the air exhaust pipe is inserted into the sampling bottle and the other end is arranged along the hand-held shank and the upright shank and is connected to an exhaust switch arranged on the hand-held shank; and one end of the water intake pipe is inserted into the sampling bottle and the other end is exposed at the opening of the sampling bottle. A plurality of trials by technicians from the district environment monitoring station show that the aqueous sample collector totally achieves the purpose of the design. The aqueous sample collector is particularly suitable for field examination and can conveniently, safely, quickly and accurately collect the aqueous samples at different depth of water within 1-3 minutes, and the aqueous samples at different depth of water do not affect each other. At the same time, the aqueous sample collector can measure the transparency of the water and be used as a bracket for an oxygen solubility measurer (water BO value), and is and is simple in structure, low in cost, and high in work efficiency.

Description

Water sampler

Technical field

The utility model relates to a kind of water sampler.

Background technology

The work of gathering water sample is very inconvenient, sometimes for the people that sample some breakneck actions of being compelled to do, sometimes at twice water (water surface reaches 20cm under water) water intaking from water be come up and then bottle with water hull, and the water of different depth is influenced mutually because of stirring, thereby influences the accuracy of testing result.Survey water transparency in addition because of there not being special ruler indeterminacy true, the detecting head of surveying the instrument of dissolved oxygen DO (water body BO value) is soft, and the water surface that can't stretch out is a little further measured water body BO value.

Monitoring personnel, the science researcher of environmental protection unit are with general acquisition cup now, directly stretch in the water with staff and sample; Or carry out grab sampling, but need power supply, many people, mechanical assistance and pedestal with the professional sampling thief expensive, that weight is big; Then use at the water surface and to sample by ship; The general irregular bamboo pole spreading handle water hull of then using stretches in the water and gathers.Above-mentioned metering system and device or cost are higher, or measuring accuracy is inaccurate.

Summary of the invention

The purpose of this utility model is to overcome the not high problem of water quality purity of dangerous property of prior art water sampling device and sampling, provide a kind of in scientific investigation, when water sample is gathered in environmental protection, need not make dangerous play and not influence the water quality detection result, once gather the water sampler of different depth and survey water transparency

For realizing above purpose, the utility model has been taked following technical scheme: a kind of water sampler, include hand holding handle and perpendicular handle that mutual bending connects, in this perpendicular handle surface indicia scale mark is arranged, on described perpendicular handle, vertically equidistantly be provided with at least one sampling bottle, each sampling bottle is to having gas outlet and water inlet pipe, this gas outlet one end inserts sampling bottle, the other end is arranged and is connected to the air discharge cook that is arranged on the hand holding handle along hand holding handle and perpendicular handle, this water inlet pipe one end inserts sampling bottle, and the other end exposes the sampling bottle bottleneck.

The principle of utilizing air to take up space is sampled, close air discharge cook during sampling earlier, sampling thief is inserted in the water, the limit insert edge is surveyed visibility, two bottles arrive proper depth in the water, at this moment occupy space in the bottle because of air, water can not enter in the bottle, open air discharge cook and discharge by air, the water of the degree of depth of living in will enter in the bottle automatically, after water is filled sampling bottle, sampling thief is left the water, back out sampling bottle, change lid, writing labels, just finish once sampling in the water quality of same sampled point different depth.So the water quality that confuses different depth because there be not bubble to produce is safety, easily and fast, sample exactly.

Described perpendicular handle is provided with at least one carriage, and described sampling bottle is positioned on the carriage.Adopt the fixing bottle that adopts of carriage, simple in structure.

Described carriage is connected with described perpendicular handle by first setting nut.This first setting nut is also fixing in order to the degree of depth of regulating bottle, convenient fixing various sampling bottle.

Also include the bottle folder, this bottle folder one end connects described sampling bottle, and the other end is connected on the described perpendicular handle.

Described bottle folder is connected with described perpendicular handle by second setting nut.

The top of described perpendicular handle also is provided with the display end that mark shows look.This display end can be used for surveying visibility.

The utility model compared with prior art, has following advantage: through the district technician's of environmental monitoring station test repeatedly, reached the target of design fully, be particularly suitable for investigating use in the open air, with the water sample that just can collect different depth in 1 ~ 3 minute convenient, safely, fast and accurately, and the water sample of different depth does not interact, guarantee to detect accurately, and can bottle immediately, visibility can be surveyed simultaneously, water transparency can be surveyed simultaneously and as the support of concentration of oxygen gas measuring appliance (water body BO value), simple in structure, with low cost, work efficiency is higher.

Embodiment

Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.

Embodiment:

See also Fig. 1 to shown in Figure 3, a kind of water sampler, include hand holding handle 1 and perpendicular handle 4 that mutual bending connects, just make of 3cm stainless steel square pipe, its length is 180cm, also can change hand holding handle 1 and perpendicular handle 4 into telescopic structure in the present embodiment, make things convenient for underwater operation and storage transportation, in these perpendicular handle 4 surface indicia scale mark 5 is arranged, on perpendicular handle 4, vertically equidistantly be provided with at least one sampling bottle 8 (present embodiment adopts three sampling bottles), 8 pairs of each sampling bottles should have gas outlet 3 and water inlet pipe 9, these gas outlet 3 one ends insert sampling bottle 8, the other end is along hand holding handle 1 and perpendicular handle 4 and be connected to the air discharge cook 2 that is arranged on the hand holding handle 1, and these water inlet pipe 9 one ends insert sampling bottle 8, and the other end exposes sampling bottle 8 bottlenecks.
