Description
Technical field
The utility model relates to a kind of portable static chamber of measuring the farmland greenhouse gas emission, belongs to the Agriculture Ecological Environment Protection field.
Background technology
Along with the increase of greenhouse gas emissions, the global warming aggravation, energy-saving and emission-reduction have obtained the attention of countries in the world, have also carried out broad research in the farmland greenhouse gas emission.The static chamber method is strong because of its adaptability, structure and simple to operate, with low cost and highly sensitive advantage, is widely used in the synchronous monitoring of terrestrial ecosystems greenhouse gas emission flux.
Employed static chamber specification shape differs in the present all kinds of research, the material that uses also has very big difference, static chamber generally is made of casing and base two parts, base need be placed in the soil before measuring, and guarantee base wall and the exchange of soil contact position airless, generally leave earlier and closed cell that the base size is similar, settle behind the base earthing all around, therefore, there is the situation of destroying the face of land and crop.According to the general requirement of field experiment, each is handled all needs a certain amount of repetition, and the static chamber quantitative requirement is more, and also needs static chamber is fetched from the farmland after observation is finished, and volume is big, there is the inconvenient problem of carrying in the static chamber of fixed in shape.
Summary of the invention
The purpose of this utility model be to provide a kind of and carry, the portable static chamber of the mensuration farmland greenhouse gas emission of convenient transportation.
Comprise in order to reach the technical scheme that this purpose takes: casing, case lid and base, it is characterized in that, case lid and casing are split type, be provided with rubber groove in the case lid bottom, be connected by this rubber groove between case lid and the casing, insert in this rubber groove the casing upper end, also is provided with anchorage clip on case lid and casing, makes described casing and case lid sealing by anchorage clip; Be provided with hinge between the wall of described casing, link to each other by adhesive tape between tank wall and the tank wall, the wall by the hinge casing is collapsible on the plane.
In the above-mentioned portable static chamber, described base bottom is provided with and base homalographic, framework that shape is consistent, and base and this framework are split type.
In the above-mentioned portable static chamber, the bottom of described framework is a zigzag.
In the above-mentioned portable static chamber, the outer rim of described base is provided with the seal groove that exceeds base.
In the above-mentioned portable static chamber, described anchorage clip be shaped as " 7 " font.
In the above-mentioned portable static chamber, be fixed with fan in the inboard of described case lid.
In the above-mentioned portable static chamber, described casing expands into rectangle.
In the above-mentioned portable static chamber, described rubber groove is located at four limits of case lid bottom, and this rubber groove internal diameter is slightly larger than the wall thickness with casing, and casing top can be inserted in this rubber groove.
This static chamber device has the following advantages: carry, convenient transportation, installation is simple, little to soil disturbance, the field in-situ observation is good, the farmland greenhouse gas emission that is particularly suitable for shape crop of short stem is measured.
Description of drawings
Fig. 1 is this portable static chamber structural representation;
Fig. 2 is the bedframe structural representation of this portable static chamber.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
This portable static chamber is made of case lid, casing, base three parts, and the casing wall is collapsible into a plane by hinge.Casing expands into rectangle.
As shown in Figure 1,1 is case lid, and 2 is rubber groove, and 4 is anchorage clip.The position that rubber groove 2 combines with casing for case lid, the internal diameter of rubber groove 2 is more bigger than wall box thickness, and when case lid was placed on the casing, wall box entered in the rubber groove of case lid, by anchorage clip 4 case lid and casing is closely linked.Anchorage clip 4 divides body structure for " 7 " word, and annulus is positioned on the case lid, and hook part is positioned on the casing, when case lid covers on the casing, last cleaner shape partly is buckled in the case lid annulus, presses down hook part then, and making between casing and the case lid by certain pressure does not have the slit; Case lid top overhead fan 3, when case lid and casing combined, fan entered box house, opens fan when carrying out gas sample, made in the case air even; Gas production hole 6 hollows are filled in rubber plug (in glass tube is arranged) during work, glass tube connects threeway, and swivel tee is collected in gas in the casing in the sampler bag by syringe; Base 7 outer rims are provided with the seal groove 8 of certain altitude, and casing covers in the seal groove 8 of base, then water are injected in the seal groove 8, and the inside and outside gas of guard box does not exchange.Link to each other by adhesive tape between tank wall and the tank wall, thereby realize sealing between the tank wall.
During operation, base 7 need be placed in the certain depth soil, for preventing excessive turbulence to soil, open tetragonal ditch with the framework identical with the base size, base of frame and soil contact position are zigzag structure, are convenient to bury, after ending ditch, framework is taken out, then base is placed soil, bury with soil all around.
After the operation, folding box body can be convenient to transportation and be carried by hinge 5.
The utility model is compared with prior art: transport easy to carry, simple to operate, required artificial fewly, little to soil disturbance, guarantee farmland original state sampling, be applicable to that dry farming farmland greenhouse gases measure.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
