Description
Technical field
The utility model is related to underground water-sampling device, and specially a kind of penetration type determines drawdown layered sampler.
Background technology
Existing water sample sampler, in-convenience in use, the characteristics of weight is larger, and water sample disturbance than larger, also not
Energy preventing water leakage, anti-stone, also need to rinse when using, be unsuitable for the sampling work with underground deep layer in the jungle of remote mountains.
Utility model content
For above-mentioned technical problem, the utility model purpose is to provide penetration type to determine drawdown layered sampler, for side
Just underground water water sampling.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
Penetration type determines drawdown layered sampler, including the collar and stack shell；Described stack shell is cylindrical structure；The described collar
At the top of stack shell；Described stack shell is suitable for reading to be provided with support；Screen pack is installed on described support；Described stack shell bottom
Portion is provided with opening, and described opening is connected through the hinge and has cover plate；Described cover plate is located in stack shell.
Further, described screen pack includes the rubber ring of annular, rubber ring middle setting screen pack；Described filtering
Net center is fixed on support；Described rubber loop diameter is big as stack shell.
Further, described stack shell is connected into including multiple cylinders, is connected through a screw thread between adjacent cylinder.
Further, there is sealing ring the contact position of described cover plate and stack shell bottom opening.
Further, described stack shell bottom lower edge is also associated with exntension tubs side.
Principle：Penetration type determines drawdown layered sampler when dropping in water, because the buoyancy of water can open cover plate 5,
Therefore water will be entered in stack shell 3 from bottom.When dropping to demand depth, then determine drawdown layering with rope lifting penetration type and take
Sample device, due to the pressure of water, cover plate 5 will be closed, and the water sample of such demand depth is retained in stack shell 3.
Penetration type determines drawdown layered sampler because its quality is small, simple to operate, carries out determining drawdown sampling very in the wild
It is convenient, typically complete in minutes；2) due to using penetration type, then drop to and can reduce the disturbance to water when in water, can
Reduce the artificial disturbance to water sample；3) due to being intake from bottom, before demand depth is dropped to, water can enter to sampler tube wall
The certain rinse effect of row, interference of the sampling to lower sub-sampling before can reducing；4) sampler upper end is close with rubber added with filter bowl
Mounting, can prevent that stone that borehole wall comes off or the stone of bottom from entering in sampler, disturbed sampling work.
The penetration type that the utility model is provided determines drawdown layered sampler, the design of penetration type is employed, so as to subtract significantly
The small disturbance to water sample, preventing water leakage, anti-stone, without rinse, simple and reasonable, own wt is lighter.
Brief description of the drawings
Constitute a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model screen pack overlooking the structure diagram；
Fig. 3 is the utility model barrel body structure schematic diagram.
Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, penetration type determines drawdown layered sampler, including the collar 1 and stack shell 3；Described stack shell 3 is cylinder knot
Structure；The described collar 1 is arranged on the top of stack shell 3；Described stack shell 3 is suitable for reading to be provided with support；It was provided with described support
Filter screen 2；The described bottom of stack shell 3 is provided with opening, and described opening is connected with cover plate 5 by hinge 6；Described cover plate 5 is located at
In stack shell 3.
As depicted in figs. 1 and 2, described screen pack 2 includes the rubber ring of annular, rubber ring middle setting screen pack；Institute
The center of screen pack 2 stated is fixed on support；Described rubber loop diameter is big as stack shell 3.
The collar 1 is used to connect rope.
Screen pack 2, is fixed on stack shell 3 suitable for reading in center, seals that stack shell 3 is suitable for reading when under current direction, and screen pack 2 stops larger
Sandstone enter stack shell 3 in.
As shown in figure 3, described stack shell 3 is connected into including multiple cylinders, it is connected through a screw thread between adjacent cylinder.Stack shell
3 interludes can apply mechanically different length cylinder, adapt to different sampling water demands.
There is sealing ring 4 contact position of described cover plate 5 and the bottom opening of stack shell 3.Cover plate 5 is hard cover body, it is to avoid hydraulic pressure
It is allowed to deform.
The described bottom lower edge of stack shell 3 is also associated with exntension tubs side 7.The extended portion 50mm of exntension tubs side 7, strengthens charge for remittance
Property, while reducing silt entrance when bottoming out.
Manufacturing process is, using the stainless-steel pipe of certain length corrosion resistance as stack shell 3, moving valve to be added in bottom
Door strengthens sealing as cover plate 5, and around valve using sealing ring 4.Steel pipe top add screen pack 2, prevent stone,
Sand enters.The graduated rope of band without ductility is added on the collar 1.
The utility model has simple and reasonable, the lighter advantage of own wt.Thermometer can also be added inside it
Or the instrument, the innovation of the structure depending on demand such as TDS recorders.Its specification is depending on sampling purposes.
