The soil profile air collecting device is simple in structure; by virtue of the inner pipe and the outer pipe, air in soil and air in the air collecting pipe can be balanced within short time in the collecting process; meanwhile, the soil air in different depths can be independently collected and tested. The soil profile air collecting device is simple in design and easy to operate.
Description
Technical field
The utility model relates to test apparatus equipment technical field, refers to especially a kind of soil profile air acquisition device.
Background technology
At present, conventional a kind of soil gas sampling instrument is different depth soil gas harvester, its structure is that gas collecting pipe top is tip-shape and sealing, on gas collecting tip end top, one circle arranges multiple apertures, gas collecting pipe upper end is communicated with connecting pipe, another termination two-way of connecting pipe, the two-way other end is communicated with syringe front end.When sampling, gas collecting pipe is inserted in the soil of different depth, sample with syringe.The method instrument is simple, but can bring gas in atmosphere into soil unavoidably in the time of sampling, soil is caused to certain disturbance, and the gas in soil in gas and gas collection tube can not reach balance at short notice, institute's sample thief can not well represent the gas in soil, brings considerable influence to measurement result.In addition, the gas in soil has certain humidity, gas analysis is measured to instrument impact used larger, brings larger error to last determination data.Other soil gas harvesters have again price high, and design is complicated, complex operation, the shortcoming that accuracy is not high.
Existing patent is such as a kind of easy device (Chinese patent Granted publication CN 203299032 U) that adopts running balancing to gather field soil gas, it is characterized in that this easy device is by gas bottle, tubulose stationary pipes, gas piping, protection stay pipe, exsiccator, gas dome, with the sample tap of rubber cap, with the syringe composition of two-way, gas bottle upper port is connected with tubulose stationary pipes, tubulose stationary pipes is embedded with gas piping one end and is connected, gas piping overcoat one hard protection stay pipe, the gas piping other end is connected with exsiccator one end of stationary pipes with two ends, the exsiccator other end is connected with gas dome by gas piping, gather volume required gas by syringe by sample tap.Although it is simple in structure, the little efficiency of gas bottle volume is high, and its acquisition range is little, soil level difference, and its position that need to extract soil gas is also different.
Summary of the invention
The purpose of this utility model is to provide a kind of soil profile air acquisition device for the problems referred to above, it can make the gas in gas and gas collection tube in soil reach at short notice balance, the soil gas of the independent collecting test different depth of energy simultaneously, simplicity of design, easy operating.
The purpose of this utility model is realized by following technical scheme: a kind of soil profile air acquisition device, comprise gas collecting pipe, some wireways and syringe, gas collecting pipe is internal and external casing structure, the mouth of pipe of outer tube is provided with sealed tube lid, in gas collecting pipe, outer tube is separated by internal partition and external partition respectively in same level, be divided into and be divided into some sealings layer of bleeding, in the internal partition of inner tube, also fixedly wear an air guide house steward, wireway is arranged in air guide house steward, each wireway tail end mouth of pipe all sets up and is placed in a sealing and bleeds in layer, wireway head end is connected with syringe, the inner tube upper end that top layer seals the layer of bleeding is fixed with a set of pipe box being through outside air guide house steward, on pipe box, there are two to extend limit, prolongation limit also further extends to bottom from inner pipe wall to outer tube wall extension and seals layer outer tube wall lower end for correspondence of bleeding, on inner and outer pipes tube wall, be respectively arranged with gas collecting hole, the width that described pipe box extends limit is slightly larger than gas collecting bore dia.
Described air guide house steward top is provided with handle, can pass through to rotate air guide house steward, thereby drives pipe box to extend the gas collecting hole that outer tube was blocked or unclamped on limit.
Described each wireway tail end is provided with a collector, for gathering separately each position soil gas.
When use, first make pipe box extend side bumper and live outer tube gas collecting hole, because the mouth of pipe of outer tube is provided with sealed tube lid, inner tube is provided with pipe box, realize the sealing of inner and outer pipes, in gas collecting pipe, outer tube is separated by internal partition and external partition respectively in same level, be divided into and be divided into the some layers of sealing layer of bleeding, now twitch syringe and discharge inner original air, then swing handle, make air guide house steward drive inner tube rotation, inner tube drives pipe box to extend limit motion, make it no longer block outer tube gas collecting hole, the sealing that now soil gas enters inner tube by outer tube is bled in layer, by syringe twitch conduit by gas to collector.
The utility model is simple in structure, arranges by inner and outer pipes, and in collection, it can make the gas in gas and gas collection tube in soil reach at short notice balance, soil gas that simultaneously can independent collecting test different depth, simplicity of design, easy operating.
