Abstract
The invention designs a micro-disturbance passive ground water sampler, which is used for monitoring a water environment. The sampler comprises an upper end water-filling flow-stopping unit, a caliber switching coupling head, a sample storage pipe and a lower end water-filling flow-stopping unit, wherein the top of the upper end water-filling flow-stopping unit is provided with a lifting rope connecting hole and is downward successively provided with a top water outlet, an upper end water storing pipe and an upper end water-filling check valve which are communicated with one another; an upper end port of the caliber switching coupling head is connected with the upper end water-filling check valve, and a lower end port of the caliber switching coupling head is connected with an upper end port of the sample storage pipe; and the lower end water-filling flow-stopping unit is successively provided with a lower end water storing pipe and an upper end water-filling check valve, which are communicated with each other, from top to bottom, and the lower end water storing pipe is connected with a lower end port of the sample storage pipe. Compared with the prior art, the micro-disturbance passive ground water sampler provided by the invention can achieve micro-disturbance ground water sampling, and can effectively prevent a collected water sample from being influenced by ground water in a well body in a sampling lifting process; and the collected water sample does not need to be stored in a sampling bottle and can be directly sent and analyzed, and thus the outside influence to the collected water sample is alleviated.
Description
Technical field
The invention belongs to the monitoring water environment technical field, specifically, relate to the moving passive type underground water sampler of a kind of perturbation.
Background technology
In groundwater environment pollution surveys, whether can accurately obtain representative underground water sample is the pith of groundwater environment pollution surveys information evaluation.Developed countries such as America and Europe in the research of underground water Sampling techniques early have very strong research and development ability, and China has also successively carried out the research work of Sampling techniques equipment.Present stage, representative underground water sampler had: Bailer sampler, discontinuous interval sampler, air bag pump, gas displacement type sampling thief, inertia lift pump etc.The Bailer sampler can be divided into bivalve Bailer sampler and single valve Bailer sampler on the structure, bivalve Bailer sampler all has a non-return valve in bottom and top, use the similar equal groundwater monitoring well of putting into to single valve Bailer sampler to carry out underground water sample sampleman work, but need to use an artificial releasing means valve open after using the Bailer sampler, again the sampling bottle of the underground water sample that takes out being packed into increases the duration of contact with air.The air bag pump is that a pliable and tough squeezable air bag is housed in a steel cylinder, and water inlet and freeing port are separately installed with non-return valve, when the air bag pump being put into monitoring well water, under the effect of hydrostatic force, water enters the pump housing by the non-return valve in the bottom, when the air bag pump is full of, and closure of check ring.Enter space between the pump housing and the gasbag ektexine at face of land injecting gas, extruding gasbag makes the pipeline that is raised to waterborne, and the non-return valve at the top can not reflux the water that enters pipeline, discharges gas air bag water-filling again.Repeat with same method, groundwater abstraction, in whole extraction process, water sample contacts with pipeline, also is not easy to simultaneously clean.
All can increase contacting of air and sample no matter be single valve or bivalve Bailer sampler in sampling process, cause some material damage of sample or the character of change sample, be difficult to obtain representative underground water sample.The bailer sampler of comparing, other sampler have the characteristics of self separately, are applicable to the sampling of different characteristic pollutant, but their sampling utility appliance is more, safeguard and clean complicatedly, cause cost to increase or feasibility descends.Therefore, design and a kind ofly can accurately obtain true underground water water sample, and have stronger operability cheaply sampling apparatus be very necessary.
Summary of the invention
