Abstract

The utility model belongs to an apparatus for measuring sand flux in sand-driving wind. The utility model is composed of a sand inlet head (1), a sand collection case (3) and a sand collection box (2), wherein, the sand inlet head (1) is provided with a plurality of square openings (4) penetrating through the upper and the lower sides of the sand inlet head (1); a lower opening of the sand inlet head (1) forms a butt joint with the sand collection case (3) of which a plurality of port inclined planes form angles of 35 DEG to 45 DEG with a horizontal direction and angles of 35 DEG to 40 DEG with a vertical direction, and orderly arranged in the sand collection box. The utility model has the advantages of simple structure, portability for field observation and convenient operation; the utility model can be widely used for application research in the aspects of sand storm physiography, ecology, sand-protecting engineering, etc.

Description

Multichannel square opening sand-taped instrument

The utility model belongs to a kind of instrument that is used for the husky flux of acoustic wind sand drift.

In the rule process between research wind direction, wind speed and drift sand, husky flux is a very important physical quantity.In the scientific experiment activity, measure husky flux must be by a kind of instrument.This instrument is placed open-air, observes for a long time, utilizes the architectural feature of this instrument, just can calculate the size of husky flux in same wind speed, different gradient, unit area, unit interval.

The utility model provides a kind of multichannel square opening sand-taped instrument from this purpose.In the observation, under the effect of certain wind speed, the sand drift that flows is stored in the grains of sand in the sand collecting box by several square holes on this instrument, pours out the grains of sand in the sand collecting box, and weighs, and so just can calculate the size of husky flux in the open air.

The purpose of this utility model can realize by following measure:

A kind of multichannel square opening sand-taped instrument is made up of sand input head (1), silt container (2), sand collecting box (3).Sand input head (1) is convex, has several to connect on its face and goes up following square opening, about boss also there is and the corresponding airflow hole of square opening face.Place mat gauze on the airflow hole, baffle plate in the oblique embedding in both sides, forms trapezoidal with the sand input head of convex.Several ports, its inclined-plane and level are 35-45 ° sand collecting box and sand input head end opening and connect, and are 35-45 ° with vertical direction and are emitted in the silt container successively; There is dividing plate top and the bottom in the silt container, and there are buckle and tapered end in both sides, and two sides are provided with vent port.

The good effect of advantage of the present utility model and generation is:

1, simple in structure, leakiness sand not, once Guan Ce time is long.It can measure in the following unit interval of same wind speed, the size of the husky flux of unit area, different gradient.

2, volume is little, and the field inspection that is easy to carry is easy to operate, and this sand-taped instrument can be widely used in the applied research of aspects such as aeolian landform, ecology, meteorology and sediment control structure.

Below in conjunction with accompanying drawing, be described in further detail again with regard to the utility model:

A kind of multichannel square opening sand-taped instrument is made up of sand input head (1), silt container (2), sand collecting box (3).Sand input head (1) is convex, the perforation square opening (4) up and down of 60 10 * 5mm is arranged on its face, about boss also there is and the corresponding airflow hole of square opening (4) (5) face, and airflow hole (5) is gone up the place mat gauze, baffle plate (6) in the oblique embedding in its both sides, and is trapezoidal with sand input head (1) formation of convex.60 12 * 6.5mm, its port inclined-plane and levels are 35 ° sand collecting box (3) and connect with sand input head (1) end opening, and be in 40 ° of dividing plates that are emitted on silt container (2) internal upper part and bottom in regular turn with vertical direction, there are buckle (8) and tapered end (9) in silt container (2) both sides, be used for fixing sand input head (1), two sides are provided with vent port (7).

Sand-taped instrument is placed on the base, is fixed on the field.When sand drift enters along horizontal direction in the square opening (4) of sand input head (1), sand drift is stopped, force sand drift to slow down, begin landing, and slide along sand collecting box (3), be stored in the sand collecting box (3), it is little because of density to be accompanied by the air-flow that sand drift enters in the square opening (4), and vent port (7) and the dividing plate (6) of the back of circling round along airflow hole (5) from silt container (2) forms the triangular space outflow with boss.

Through certain hour, open the tapered end (9) and the buckle (8) of silt container (2), take off sand input head (1), pour out the grains of sand in the sand collecting box (3) in order, after weighing, just can calculate the size of the husky flux of different gradients.

Claims

1, a kind of multichannel square opening sand-taped instrument, be by sand input head (1), silt container (2), sand collecting box (3) are formed, it is characterized in that: sand input head (1) is convex, having several to connect on its face and go up following square opening (4), about boss also there is and the corresponding airflow hole of square opening (4) (5) face, and airflow hole (5) is gone up the place mat gauze, plate washer (6,6 ') in the oblique embedding in its both sides, and is trapezoidal with sand input head (1) formation of convex; The end opening that several ports, its inclined-plane and level are 35-45 ° sand collecting box (3) and sand input head (1) connects, and is 35-45 ° with vertical direction and is emitted in regular turn in the silt container (2).

2, according to the described multichannel square opening of claim 1 sand-taped instrument, it is characterized in that: there is dividing plate the interior upper and lower part of silt container (2), and there are buckle (8) and tapered end (9) in both sides, and two sides are provided with vent port (7).
