Abstract
The utility model discloses a field different-gradient vertical fall dust collector which is characterized in that a dust collecting glass bottle is arranged in a stainless steel protective cylinder, wherein a stainless steel funnel is inserted in the mouth of the bottle; the stainless steel funnel is filled with glass balls of 5-10mm; the glass balls are covered with a stainless steel separation net; and an open stainless steel dust falling cylinder is embedded inside the stainless steel protective cylinder and then the open stainless steel dust falling cylinder and the stainless steel protective cylinder are placed in a bracket frame. The field different-gradient vertical fall dust collector provides a test method for collecting sand dust falling vertically from different gradients in gravel desert and adds data for researching the wind-blown sand flow in the gravel desert.
Description
Technical field
The utility model relates to a kind of open-air utensil of collecting sand and dust that is used for.
Background technology
Sedimentary loading (rate) is the key problem of stream research, also is to estimate the extremely important index of hazards of sand storms.The scientific worker draws through wind tunnel simulation test and long-term field observation test: the stressed mechanism of particle comprises two aspects, the one, and starting moment stressed, the 2nd, particle stressed in the saltation process.On the sandy face of land, the increase of silt discharge resistance height is to reduce the influence that process receives factors such as wind speed and underlying surface, along with the increase of wind speed.0～the 1cm of lower floor is relative, and silt discharge reduces, middle level 1～2cm, and silt discharge slightly becomes relatively, or increases or subtract; Upper strata 1～2cm increases.Underlying surface to the influence of Structure of wind-Sand Flow very significantly, and is also very complicated, and because of surface relief, material is formed to the change of Structure of wind-Sand Flow for it, and exposed different and different of moisture number and vegetation do not have the pattern of fixing and can lead.The Gobi desert also is the more frequent place of wind-sand activity; But there is tangible difference on the structure of its stream and the sandy face of land; So, what does the Gobi desert wind-sand activity have different with the sandy face of land at dust storm flow (sedimentary loading) and distribution (Structure of wind-Sand Flow), velocity distribution and energy-structure?
The utility model content
Based on above-mentioned, the purpose of the utility model aims to provide the vertical depositing dust gatherer of the different gradients in a kind of field, utilizes this utensil can collect the serrir strong wind sand and dust of the vertical landing of gradient from different places, so that carry out scientific research.
The purpose of the utility model is achieved in that
The vertical depositing dust gatherer of the different gradients in a kind of field is made up of uncovered stainless steel depositing dust tube, stainless steel separation net, glass bead, stainless steel funnel, control of dust vial, stand frame and support fixed transverse rod.The control of dust vial places in the stand frame, and bottleneck is inserted with the stainless steel funnel, and the stainless steel funnel fills 5～10mm glass bead, hides the stainless steel separation net on the glass bead; Stainless steel funnel and control of dust vial occupy uncovered stainless steel depositing dust tube and the bottom stainless steel depositing dust tube inside of embedding mutually.
The advantage of the utility model and the beneficial effect of generation are:
1, the gatherer of the utility model development, for collect serrir from different places the sand and dust of the vertical landing of gradient research technique is provided, for research serrir local wind sand drift has increased data.
2, the utility model is simple in structure, and is easy to loading and unloading, can collect the sand dust of different serrir local wind sand drifts.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is a gatherer enlarged diagram among Fig. 1.
Embodiment
Shown in Fig. 1-2; The vertical depositing dust gatherer of the different gradients in a kind of field is made up of uncovered stainless steel depositing dust tube 2, stainless steel separation net 3, glass bead 4, stainless steel funnel 5, control of dust vial 6, stainless steel protection tube 7, stand frame 9, support fixed transverse rod 10 and retort stand 11.Stand frame 9 is connected with support fixed transverse rod 10, and support fixed transverse rod 10 is connected with support 11.Control of dust vial 6 places in the stainless steel protection tube 7, and control of dust vial bottleneck is inserted with stainless steel funnel 5, and stainless steel funnel 5 fills 6mm glass bead 4, hides 10 order stainless steel separation nets 3 on the glass bead 4; Uncovered stainless steel depositing dust tube 2 embeds in the stainless steel protection tube 2, covers stainless steel funnel 5 and control of dust vial 6, and places in the stand frame 9.
On the different gradient of retort stand 11, gatherer support fixed transverse rod 10 is connected with retort stand 11, when stream swept, sand and dust particle 8 got into from nozzle 1, through 10 order stainless steel separation nets 3 in the uncovered stainless steel depositing dust tube 2, on the landing glass bead 4.Under the action of the rotating air, dust particle 8 for the ball 4 from the glass cracks Uu dust falling through the stainless steel hopper 5 bottles 6.Lay down uncovered stainless steel depositing dust tube 2, take out the stainless steel funnel 5 that fills glass bead 4 from control of dust vial 6.Get different gradients, the control of dust vial 6 in same place, labelled then, pour out control of dust vial 6 depositing dusts respectively, weigh, and carry out record.
Test shows; Serrir strong wind area 0～10m height silt discharge is with different differences to some extent highly different and face of land character, and wind speed is bigger, and the height of atmosphere sand and dust saltation is bigger; Sedimentary loading is the index minimizing with the increase of height; Along with wind speed increases, lower floor's sedimentary loading reduces relatively, has relatively increased the sand dust of carrying in the air-flow of upper strata.
