Description

A kind of pump suction type ground water fixed depth harvester
Technical field
The utility model is related to Geotechnical Engineering and field of environment engineering, and in particular to a kind of pump suction type ground water fixed depth collection Device.
Background technology
China's soil and groundwater pollution problem is increasingly serious, and pollution can bring huge danger to health and living environment Evil.With the adjustment of the industrial structure in recent years and the quickening of urbanization process, having left many after a large amount of industrial enterprise's resettlements can The contaminated site that health of human body can be caused harm, if developing again, it is necessary to which necessary investigation is carried out to these places Or repair;Monitoring well technology is the basis of place Groundwater Contamination Investigation, by it may determine that groundwater pollutant composition, Many parameters such as distribution and migration path.With detecting instrument fast development and pollutant kind increase, we Multiple field distribution can be presented in underground water by recognizing the pollutant of different chemical attributes, and traditional monitoring sampling technique is Can not accurately reaction contaminant and the hosting relation of Tu Shui rock stratum.
The spatial distribution and concentration for understanding pollutant are to carry out the premise that contaminated site is administered and repaired.May 11 in 2012 Day, Chinese Ministry of Land and Resources《2011 Chinese land resources publications》Issue towards the society, publication show Chinese city underground water compared with Difference, extreme difference level ratio are more than half, and national groundwater quality situation allows of no optimist.When carrying out the investigation of such space enrironment, sampling The quality of quality is most important to the authenticity of environmental survey data.Therefore, effective and accurate sampling method how is selected, It is the hot issue of environmental survey concern quick and precisely to find out its distribution.
Developed country pays much attention to Groundwater Contamination Investigation sampling technique, and sampling technique is also conducted in-depth research, The sampler compared with multiple types is have developed, the country does not occur also rapidly descending water sampling equipment at present, and traditional monitoring well underground The water sampling cycle is longer, and institute's water sampling is mixed sample, it is impossible to accurately react Tu Shui relation.Therefore, pumping depthkeeping is developed Sampling techniques advantage, can solve above mentioned problem, with practical value.
The content of the invention
The purpose of this utility model is according to there is provided a kind of pump suction type ground water fixed depth in place of above-mentioned the deficiencies in the prior art Harvester, the harvester can prevent suck-back by pumping principle, and contaminated site ground water fixed depth can be sampled.
The utility model purpose is realized and completed by following technical scheme:
A kind of pump suction type ground water fixed depth harvester, it is characterised in that the harvester includes vavuum pump, storage chamber And intake pipe, one end of the intake pipe is in the storage chamber, and the other end is water acquisition mouthful, the vavuum pump and the retaining Chamber is connected by communicating pipe, and the storage chamber is provided with sample tap.
There are dial markings on the intake pipe.
There is flow control valve on the vavuum pump.
The storage chamber is vacuum tank, and the tank base sets hold-down support.
The intake pipe is polyfluortetraethylene pipe.
Oak plug or rubber stopper seal are used between the storage chamber and the intake pipe and the communicating pipe.
Oak plug or rubber stopper seal are used between the vavuum pump and the communicating pipe.
The utility model has the advantages that, using pump suction type ground water fixed depth harvester can quick sampling at set depth, prevent not Water sample with pollution layer is mixed;And the device is not strict to field condition requirement, simple in construction, easy to carry, but also Battery can be connect to use, foundation is provided for follow-up investigation, improvement, greatly save time and cost.
Brief description of the drawings
Fig. 1 is the structural representation of pump suction type ground water fixed depth harvester in the utility model.
Embodiment
Feature of the present utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with accompanying drawing It is bright, in order to the understanding of technical staff of the same trade:
Mark 1-7 is respectively in such as Fig. 1, figure:Intake pipe 1, hold-down support 2, storage chamber 3, vavuum pump 4, sample tap 5, company Siphunculus 6, flow control valve 7.
Embodiment:As shown in figure 1, the present embodiment is specifically related to a kind of pump suction type ground water fixed depth harvester, this collection Device is to carry out sampling at set depth to contaminated site underground water by pumping principle.
As shown in figure 1, the pump suction type ground water fixed depth harvester of this in the present embodiment by be sequentially connected vavuum pump 4, store Water cavity 3 and intake pipe 1 are constituted, wherein, one end of intake pipe 1 is water acquisition mouthful, and indicates dial markings, for testing into the depth of water Degree, the other end is accessed from the top of storage chamber 3 and to the bottom of storage chamber 3, and the junction of intake pipe 1 and storage chamber 3 uses rubber Stopper or rubber stopper seal;The storage chamber 3 is positioned on hold-down support 2, and storage chamber 3 is vacuum tank, in the centre of its tank body Position offers sample tap 5, and storage chamber 3 is connected by communicating pipe 6 with vavuum pump 4, and in storage chamber 3 and the company of communicating pipe 6 The place of connecing and communicating pipe 6 and the junction of vavuum pump 4 are sealed using oak plug or rubber stopper.
As shown in figure 1, the material of the intake pipe 1 in the present embodiment is polytetrafluoroethylene (PTFE), it can be prevented from polyfluortetraethylene pipe Major structure into underground water secondary pollution, and with decay resistance.
As shown in figure 1, the storage chamber 3 in the present embodiment specifically uses detachable structure, it is easy to cleaning, in order to avoid retaining Chamber 3 causes the secondary pollution of water sample, influences water sample detection result.
As shown in figure 1, the vavuum pump 4 in the present embodiment is dry vacuum pump, flow control valve 7 is provided with, is passed through Regulation pumping power can be such that gathered aqueous sample stream slowly exits into so as to control the flow of water acquisition by adjusting flow valve 7 In storage chamber 3.
As shown in figure 1, extracting the concrete operations of water sample using the pump suction type ground water fixed depth harvester in the present embodiment Step is as follows:
(1)The harvester is assembled, vavuum pump 4, storage chamber 3 and intake pipe 1 are sequentially connected, each pipeline is connected, Ensure that sealing of the intake pipe 1 with the junction of storage chamber 3, and the both ends of communicating pipe 6 connect with storage chamber 3 and vavuum pump 4 respectively Connect the sealing at place;
