Abstract
The utility model relates to an all position fixed-point sand-collecting instrument. The utility model is mainly composed of a probe head, sand-shielding plates, sand-leading channels, sand-collecting boxes, an exhaust pipe, a protection box, an upper cover plate and a lower cover plate. The probe head is a cylinder, and square holes which are longitudinally interlaced are distributed on the surface of the probe head; the opening of each transversal sand-shielding plate (3) in the holes warps downwards to form longitudinal separated and perforated sand channels to be communicated with umbrella-shaped sand-leading channels on the lower end of the utility model; the exhaust pipe and the probe head are the same center of a circle, and the exhaust pipe is positioned in the probe head. The probe head and the protection box are on a strip of center line, and the probe head passes through the upper cover plate and the lower cover plate to be vertically arranged on the upper part of the protection box; the sand-collecting boxes are arranged around the circumference in the protection box, and each sand-leading channel is corresponding to each sand-collecting box. The utility model has the advantages of simple structure and convenient use. Under the special environment that no people watch the sand storm, the utility model can also collect the shifting sand of different directions to establish correlation for data which is measured, wind directions and wind speed.
Description
The utility model belongs to a kind of instrument that is used for the husky flux of acoustic wind sand drift.
China is one and is subjected to desertification to corrode more serious country.Whole nation desertification land has reached 35.8 ten thousand square kilometres, accounts for 3.7% of national land area, and desertification land is still with 2100 square kilometres/meter speed increment.Must study dust storm flowing law and dust storm and environmental relation in order to effect a radical cure desertification.In the scientific experiment activity, the mensuration of husky flux needs the multi-faceted collection observation data of long-term fixed point, and require the observed result of husky flux to set up mutual relationship with wind speed, wind direction, so that carry out the research and the engineering calculation of stream, just need a kind of comprehensive sand-taped instrument that can distinguish different wind direction sand drifts of development, to realize the comprehensive collection of husky flux.
The utility model is from this purpose, provides a kind of measurement convenient comprehensive, the sand-taped instrument of long-term fixed point, with this be implemented in unattended or the sandstorm specific environment under, obtain the collection of unit area drift sand in the unit interval.
The purpose of this utility model can realize by following measure:
A kind of comprehensive fixed point sand-taped instrument, mainly by the probe (1), partition (2), shelves husky plate (3), draw husky passage (4), silt container (5), gas outlet (6), guard box (7), cover plate (8,9) is formed up and down.Probe (1) is cylindric, and it is little that the big end of several mouthfuls is formed by crisscross partition (2) and the husky plates of shelves (3) in its surface, like bucket-shaped square hole, and affixed with gas outlet (6); The husky plate of each grade (3) opening is 45 ℃ of angles towards having a downwarp with vertical partition (3) in the hole, forms the husky road that vertically is separated by.And be husky passage of drawing of umbrella (4) with the lower end and connect, gas outlet (6) and probe (1) are the cylinders in the same center of circle, are positioned at probe (1) central authorities, and probe (1) and guard box (7) are on a center line; Probe (1) passes cover plate (8,9) up and down, directly erects in the top of guard box (7); Be placed with silt container (5) around circumference in the guard box (7), it is corresponding with each silt container (5) that each draws husky passage (4).
The good effect of advantage of the present utility model and generation is:
1. the utility model adopts the husky probe of the comprehensive collection of cylinder, the surface of probe is furnished with crisscross square hole, each vertical husky road connects, and being husky passage of drawing of umbrella with the lower end is connected, therefore can collect the drift sand of different azimuth easily, data that record and wind direction, wind speed data are set up correlationship.
2. comprehensive fixed point sand-taped instrument is simple in structure, easy to use, can be widely used in the research of directions such as forestry, ecology, blown sand physics and railway, highway, reservoir, the observation of industrial and mineral sand-prevention engineering benefit, is the requisite a kind of instrument of observation stream.

Below, be described in further detail with regard to the utility model in conjunction with the accompanying drawings:
A kind of comprehensive fixed point sand-taped instrument, mainly by the probe (1), partition (2), shelves husky plate (3), draw husky passage (4), silt container (5), gas outlet (6), guard box (7), cover plate (8,9) is formed up and down.Probe (1) be 10 centimetres of diameters, high 50 centimetres cylinder, its surface by a crisscross partition (2) and the husky plates of shelves (3) form several mouthfuls greatly the end little, bucket-shaped square hole seemingly, and affixed with gas outlet (6).The husky plate of each grade (3) opening forms 16 husky roads that vertically are separated by towards having a downwarp, being 45 ℃ of angles with vertical partition (2) in the hole, and is 16 of umbrella with the lower end and draws husky passage (4) and be connected.Gas outlet (6) is arranged in probe (1), and probe (1) and guard box (7) are on a center line; Probe (1) passes cover plate (8,9) up and down, directly erects in the top of guard box (7), is placed with silt container (5) around circumference in the guard box (7), and it is corresponding with each silt container (5) that each draws husky passage (4).
During measurement; earlier the guard box (7) of comprehensive fixed point sand-taped instrument is imbedded sand ground; and it is equal with sand ground; open lower cover (9), the circumference of silt container (5) around guard box (7) sequenced; probe (1) passes upper and lower cover plate (8,9), and it is corresponding with each silt container (5) that each is drawn husky passage (4).Tighten upper and lower cover plate (8,9), opening entry time, wind direction, air speed value then with bolt.Enter the square hole of the husky probe of survey (1) when the stream along continuous straight runs after, because sand drift has the resistance shelves of the husky plates of shelves (3) at 45 ℃ of angles, force the sand drift deceleration, change flow direction, the grains of sand begin landing, flow into to draw husky passage (4).At last, the grains of sand are pooled to silt container (5), and air-flow flows out from gas outlet (6).Through one section for a long time, open upper and lower cover plate (8,9), pour in the cloth bag sand of silt container (5) into Weighing by the direction order.Enter what of the husky amount of silt container (5) from unit area and unit interval, can calculate the size of husky flux.
