Description
Technical field
The utility model relates to a kind of for the depthkeeping piston type water sampler of surface water body as different depth water samplings such as rivers, lake and oceans.
Background technology
Along with developing rapidly of Chinese society economy, many rivers and lakes suffer artificial pollution, have badly influenced life and the production of the mankind.Therefore, surface water quality monitoring becomes particularly important, and surface water water sample collection work ensures water quality monitoring work prerequisite accurately.The water sampler of present stage is very simple nothing the matter for collecting the water sample that underground water is surperficial or surface water body is surperficial, but the water sample gathering the following certain depth of ground water level or surface water body surface is just more difficult, because be easy to be mixed into the water in the nonspecific degree of depth before certain depth rendered to by collector, actual acquisition to be the mixed sample comprising water on different depth.What the utility model designed is can prevent from being mixed into water sample in the nonspecific degree of depth in collector launch process and only gathering the special water sampler of the one of water sample in certain depth.
We found some problems when gathering water sample in the past: in sampling process, use general container, arbitrarily gather, for sampling depth and the very difficult accurately guarantee of purity of water sample, therefore, under these inaccurate conditions, water sample analysis is carried out, measured conclusion, is also difficult to very accurate.These problems are all because sampling instrument is outmoded, use inconvenience, and hamper carrying out smoothly of water sampling, therefore, are necessary, to the instrument of water sampling, to improve.
Summary of the invention
The purpose of this utility model is to provide that a kind of volume is little, easy to carry, structure is simple, easy to operate, practical, be convenient to the depthkeeping piston type water sampler carrying out water sampling at rivers,lakes and seas different depth.
The utility model discloses one: a kind of depthkeeping piston type water sampler, comprise a cylindrical shell 8, it is characterized in that: the upper end of cylindrical shell 8 is provided with cable 1, the upper through hole 9 be connected inside and outside described cylindrical shell 8 top is provided with, described cylindrical shell 8 inside is provided with a piston 4, under the effect of water pressure, described piston 4 can slide up and down along cylindrical shell 8 inwall; A weight base 5 is provided with, the lower through-hole 6 be connected inside and outside being provided with bottom cylindrical shell 8 bottom cylindrical shell 8.
Preferably, described cable 1 is preferably provided with size scale line.
Preferably be provided with draw ring 2 in the upper end of cylindrical shell 8, described cable 1 is connected with cylindrical shell 8 by draw ring 2.
Preferably, described weight base and cylinder body bottom are for removably connecting.Described weight base 5 with bottom cylindrical shell 8 for being threaded.
The connected mode of described weight base and cylindrical shell bottom can be: described weight base 5 is annular base, and bottom described cylindrical shell 8 just on setting-in and described annular base, described annular base inwall is provided with internal thread, is provided with external thread bottom described cylindrical shell 8.
Also can be: described weight base 5 is cup dolly, centre is provided with shrinkage pool groove 11, and described shrinkage pool groove 11 is provided with shrinkage pool 10, and described shrinkage pool 10 is connected with the lower through-hole 6 bottom described cylindrical shell 8, described shrinkage pool groove 11 inwall is provided with internal thread, is provided with external thread bottom described cylindrical shell 8.
As optimal way, described cylindrical shell 8 is provided with adjustable water discharging valve 7 and cylinder handle 3.Described cylindrical shell 8 is made for stainless steel; Described piston 4 is provided with O-ring seal.
Weight base set by cylinder body bottom, be convenient to water sampler and sink down into the degree of depth reaching various needs under water, connecting thread 12 between weight base and cylindrical shell, can the cylindrical shell of water sample acquisition device for convenience detach and base, be convenient to the clean of device, to ensure water sample analysis accuracy, the also base of replaceable Different Weight, reach the range of choice increasing the degree of depth, improve water sampling efficiency.
Utility model works principle:
When cylindrical shell gos deep in water in the draw of cable, under hydraulic pressure effect, in the piston upwards top set that described inner barrel is arranged, water enters from cylinder body bottom hole and is full of cylindrical shell, when upwards pulling cable, under inertia effect, piston moves downward and returns to bottom, allow the water sample needed enter cylindrical shell from upper through hole, unwanted water sample cylinder body bottom lower through-hole is discharged; The weight base that cylinder body bottom is installed, is convenient to water sampler and sinks down into the various degree of depth under water.The set upper through hole in described cylindrical shell top is the manhole being positioned at center, described weight base and the lower through-hole size and location set by cylinder body bottom and upper through hole suitable.Adjustable water discharging valve set by cylindrical shell bottom, can discharge the water sample of collection.
The relative motion of piston and stainless steel cylinder inwall adopts and straight up and down designs, cable is connected with stainless steel cylinder, and cable has size with a scale, for throwing in water sampler to certain depth, under the inertia effect of hydraulic pressure and cylindrical shell, piston and stainless steel cylinder inwall is made to produce relative displacement.Waterproof problem between piston and stainless steel cylinder inwall, makes it just can play waterproof action by adjustment O-ring seal size and thickness, can not make again to produce too large friction force between O-ring seal and stainless steel cylinder inwall.Through hole is provided with in cylindrical shell upper end, when using cable to be placed in water by cylindrical shell, piston in cylindrical shell will move upward, this is because under hydraulic pressure effect, water sample in the nonspecific degree of depth enters cylindrical shell from cylinder body bottom hole, after cylindrical shell arrives certain depth, cable is pulled to drive cylindrical shell subsequently, piston in cylindrical shell will move downward under inertia effect, thus nonspecific water sample is discharged from cylinder body bottom, outside specific water sample enters into inner barrel from through hole cylindrical shell, and be stored in cylindrical shell, simultaneously due to the final balance of pressure, even if be suggested at collector in the process of the water surface and also can not be mixed into other water samples.
Compared with prior art, the utility model has that volume is little, easy to carry, structure is simple, manual operation flexibility and reliability, and not fragile, lightweight, easy to operate, practical advantage, is convenient to carry out water sampling at rivers,lakes and seas different depth.
