Description
Technical field
The utility model is related to the devices that sampling of ground water is taken in hydrographic survey field more particularly to a kind of ground observation.
Background technology
In the wild when the hydrology such as prospecting, water quality monitoring, groundwater supply prospecting monitoring, it is required for taking underground water water sample point
Its physics and chemical index are chemically examined in analysis.
It is required according to geotechnical investigation code, prospecting in the wild needs to acquire groundwater sample when boring chance level of ground water, for analyzing
Test physics and the chemical index such as the corrosivity of water.Because of surface and the superficial part of underground water level, easily by peripheries such as ambient atmospheres
The influence of environment, sample often do not have representativeness.So geotechnical investigation code requires the underground water water sample taken to answer water located underground
Or less 0.5m or following.
Existing water fetching device is unable to ensure water intaking water level and complicated, is convenient for taking therefore, it is necessary to a kind of water intaking is convenient
The device of band.
Utility model content
The utility model is in view of the deficiencies of the prior art, it is proposed that a kind of ground observation takes the device of sampling of ground water, should
Device has the characteristics that simple in structure, easy to use, high certainty of measurement and safeguards to be easy.
It includes tape measure and stainless steel drum that a kind of ground observation, which takes the device of sampling of ground water,；
It is connect at the top of the tape measure and stainless steel drum；
The stainless steel circle is in closed thick-wall hollow shape；
A head cover that hingedly can freely open, the bottom of the stainless steel drum is arranged in the top of the stainless steel drum
Thread button；
There are one round stainless steel flat plate pedestal, the circle stainless steel flat plate pedestals for the setting of stainless steel drum bottom
It is threadedly coupled by screw thread with stainless steel drum bottom；
A circular hole is opened on the circle stainless steel flat plate pedestal, and one is hingedly fixed on the circle stainless steel flat plate
The outer surface of the stainless steel steel ball of rod failure, the steel ball of stainless steel includes flexible rubber foreskin, so that steel ball under the effect of gravity can
Closed circular hole.
The advantageous effect of technical solution described in the utility model is：Using Archimedes' principle, setting hinged-support connects
The stainless steel ball sealer of flexible rubber foreskin is wrapped up in outer surface, utilizes standing balance（Equalising torque）, automatically turn on and blind hole
Hole, water sample that can be below precise acquisition to level of ground water at 0.5 meter.Described device using the common tape measure of ground observation as
Traction piece, the stainless steel cylinder made of easy processing make sampling container, the movable unlatching with hinged-support and closed stainless steel
Inlet opening is opened and be closed to ball, has simple in structure, easy care, the characteristics of being hardly damaged.The processing and fabricating cost of described device
It is cheap, have the advantages that be realized with a low cost precise acquisition representative sample, meets code requirement, it is economical and practicability
Feature.
Description of the drawings
Fig. 1 is the apparatus structure schematic diagram for the device that a kind of ground observation described in the utility model takes sampling of ground water.
Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, with reference to specific embodiment to this
Invention is described in further detail.
The basic conception of device described in the utility model is to utilize the common tool of ground observation, builds a set of simple dress
It sets, can quickly and accurately take the groundwater sample of high quality, meet the requirement of geotechnical investigation code.
Such as Fig. 1, it includes 1 He of tape measure that a kind of ground observation described in the utility model, which takes the device of the device of sampling of ground water,
Stainless steel drum 2；The tape measure 1 is connect with 2 top of stainless steel drum；The stainless steel drum 2 is in closed thick-wall hollow shape；Institute
A head cover 6 that hingedly can freely open is arranged in the top for stating stainless steel drum 2, and the bottom thread of the stainless steel drum 2 is buckled；
2 bottom of stainless steel drum setting there are one round stainless steel flat plate pedestal 4, the circle stainless steel flat plate pedestal 4 with not
2 bottom of rust steel drum is threadedly coupled by screw thread；A circular hole 5, the circle are opened on the circle stainless steel flat plate pedestal 4
The stainless steel steel ball 3 of a rod failure, the flexible rubber of outer surface package of stainless steel steel ball 3 are hingedly fixed on stainless steel flat plate pedestal 4
Glue foreskin, so that steel ball under the effect of gravity can closed circular hole.
Based on above-mentioned technical characteristic, technical solution realization principle described in the utility model is as follows：
According to Archimedes' principle, the stainless steel cylinder of a heavy wall is designed（Sink with enough gravity）, bottom is opened
There are circular aperture, setting hinged-support to connect the stainless steel ball of flexible rubber package, when buoyancy is less than steel ball gravity, water is not
It can enter in stainless steel cylinder water sampling container, stainless steel cylinder is closed；When the bottom surface of stainless steel cylinder enters underwater 0.5m
Place and it is following when, buoyancy is more than or equal to the gravity of stainless steel ball, and stainless steel ball jacked up, and circular hole is opened, and flow enters not
It becomes rusty in steel cylinder, when external water pressure in stainless steel cylinder balances, stainless steel is in residual gravity（Remove the weight of natural buoyancy part
Power）Under the action of sink, close water inlet circular hole, go out wellhole mouth at this point, being promoted and containing the stainless steel cylinder of water sample, open hinged-support
Water sample is poured into the container of water storage sample by the head cover of half opening, that is, completes the gatherer process of water sample.
The device of sampling of ground water is taken to be described in detail a kind of ground observation provided by the utility model above,
The principle and implementation of this application are described for embodiment used herein, the explanation of above example is only intended to
Help understands the present processes and its core concept；Meanwhile for those of ordinary skill in the art, the think of according to the application
Think, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification should not be construed as pair
The limitation of the application.
