The piston type visible water sample collection instrument can be used for collecting water bodies such as rivers, lakes, reservoirs and the like, and has the characteristics of good fidelity, high precision, good representativeness, low manufacture cost and the like.

Description

The visual water sampling instrument of a kind of piston type

Technical field

The invention belongs to environmental monitoring, environmental improvement and water body sample collection technical field, relate to the water body sample collection of river, lake, reservoir, specially refer to the water body sample collection that contains the more or water body complex shape of suspension.

Background technology

The collection of water body sample is the basis of water pollution control and research with preserving.Along with passage of time, the build-up effect of environmental problem is more and more outstanding.How effectively to gather representative water body sample and become the key of water environment treatment and research.The bottom of the water bodys such as river, lake, reservoir deposits a large amount of depositeds or flocculation state pollutant, affects water quality.Especially in the Northeast of China, Multi-year average precipitation is little, and reservoir water yield law of commutation is low, through operation for many years, and reservoir lower floor ubiquity flocculate depositional phenomenon, seriously polluted.Along with economic development, many agricultural water reservoirs change urban water supply reservoir into, and the transformation of water target improves water quality standard greatly.Actual reservoir is in service, and the water quality burst accident repeatedly making a very bad impression has also occurred.These problems all have substantial connection with water body lower floor water quality, and therefore the water sample of lower floor's water body extracts becomes the key studying a question.

In the time of water sampling, what need to guarantee collection is the water sample under designated depth virtual condition, and this just relates to the problems such as depth localization, water body exchange, water sample form.The existing multiple technologies of depth localization can solve, but water body exchange is not only relevant also relevant with water body form with the structure of hydrophore, need in flow velocity direction, there is stronger exchange capacity for river water, need on vertical, have stronger exchange capacity for hydrostatic bodies such as lakes.In order to further investigate water pollution problems, always wish to obtain more Water-Body Information simultaneously, for example, observe situation under water, measure temperature, the depth of water etc.In sum, the representative water body sample of the collection of efficiently and accurately need possess the function of the moving sample collection of polymorphic perturbation and Water-Body Information collection.

At present, for superposed layer water sampling, conventional pump suction type hydrophore, Nice gold urn based on " open-close " principle and the hydrophore of Nansen bottle and horizontal water sampler and improved form thereof of mainly containing.Wherein pump suction type, for example summer peristaltic pump depth sampler that (2006) are introduced of improving oneself, can gather the water sample of different depth, but larger to water disturbance while sampling, especially the flocculent substance in water body is destroyed seriously, directly affects the representativeness of water quality sample; Based on Nice gold urn and the Nansen bottle of " open-close " principle, the pressed cover hydrophore that for example German HYDRO-BIOS company produces, little compared with pump suction type to water disturbance, but be only applicable to the hydrostatic bodies such as Hu Ku, for current water exchange capacity deficiencies such as rivers; Horizontal sampling thief is applicable to the current waters such as river but for hydrostatic water bodys such as Hu Ku, water exchange capacity is insufficient; The Multi-Limnos automatic water sampler water intake mode that HYDRO-BIOS company of Germany produces is unidirectional water inflow, larger to the floccus disturbance in water body; The CTD48M conductivity-temperature-depth system that SST company of Germany produces can be measured the depth of water, temperature, salinity, but it expensively reaches 100,000 RMB, and salinity index of correlation can gather water sample and goes back to laboratory and analyze.

Obviously, aforementioned device does not all possess the moving sample collection function of polymorphic perturbation, the water sampling that especially contains for reservoir lower floor the flocculation state that suspends.Need research and development to there is perturbation moving (not destroying floccus in water body), be applicable to the sampling thief of the functions such as situation under variform, observation water.

Summary of the invention

The technical problem to be solved in the present invention is to provide a set of floccus in water body that do not destroy, the water body sample collecting device that is applicable to the multiple fluidised forms such as water body that suspended state content of material is large and river, lake, reservoir, this device also possesses regimen observation, the degree of depth and temperature measuring function.

Technical scheme of the present invention is:

Visual water sampling instrument, mainly contains and is with graduated hawser, trigger, buffer board, staving and piston mechanism composition.

Embodiment

Describe the specific embodiment of the present invention in detail below in conjunction with technical scheme (and accompanying drawing).

The concrete implementation step of the visual water sampling instrument of piston type water sampling is as follows:

Step 1: buffer board 4 is connected with the top of staving 5 by bolt 10, the water inlet end of staving 5 will be placed in piston mechanism 6, on counterweight 7, now the water inlet end of staving 5 has sufficient water exchange with the water body that gathers, and can guarantee that the water sample gathering is really the water sample of desired depth.

Step 2: now hawser 9 is enclosed within on bolt 3-5 during in normal condition at the spring 3-3 of trigger 3, now, the part of hawser 1 with scale below sling 3-6 is in relaxed state, package unit is stressed by the above part of the hawser 1 sling 3-6 with scale and hawser 9, to trigger hammer 2 through hawsers 1 with scale, and by trigger 2 be held in the hand with the head of scale hawser 1.

Step 3: piston type water sample Acquisition Instrument is put into water, see and look into lower water depth by the hawser 1 with scale, wait while arriving desired depth, discharge from hand and trigger hammer 2.

Step 4: trigger hammer 2 along the 1 time drop impact trigger board 3-1 of hawser with scale, lower pressing spring 3-3 is to support column 3-4, make trigger board 3-1, fixed head 3-8, bolt 3-2 and bolt 3-5 move down, stressed plate 3-7 is not hauled and is moved down by hawser 2, the now bolt 3-5 stressed plate 3-7 that submerges, hawser 9 comes off, the following part of hawser 1 sling with scale starts stressed, staving 5 falls in the effect of deadweight and counterweight 10, the relative staving 5 of piston mechanism 6 rises, when staving 5 falls, buffer board 4 has slowed down by aperture draining the speed falling simultaneously, reduce the broken ring to water body flocculent substance, until piston mechanism 6 rises to buffer board 4, now underwater sample collection finishes.

Step 5: pull the hawser 1 with scale that device is carried to ship (bank).First watch the original physical state of water sample, Taking Pictures recording.Transfer piston mechanism 6, the water sample of collection is proceeded in sample storing device and preserved, so that the later stage is done correlation analysis, so far sampling finishes.
