Description
Technical field
The present invention relates to a kind of instrument that is used for monitoring the atmospheric environment sand dust, particularly a kind of can the comprehensive wind direction condition of Quantitative Monitoring under the instrument of sand flow.
Background technology
The stream motion is the principal mode of dust storm motion and the major reason of desertification of land, and its motion directly causes soil drifting or accumulation.The long-pending phenomenon of the erosion in the research stream characteristics of motion and desertification soil need be carried out long-term position monitor to dust and sand weather and desertification soil by instrument and equipment.Structure of wind-Sand Flow research at present is mainly by " the long-pending husky instrument " of USSR (Union of Soviet Socialist Republics) and derive similar instrument and have many qualitative results, but still do not have the instrument of quantitative measurement sand flow.And drift sand flux and the stream total flow of unit ventilation section in the unit interval is the requisite major parameter of the research dust storm characteristics of motion, also is the key factor of monitoring soil drifting intensity and desertification degree.
Summary of the invention
The defective that exists from above-mentioned monitoring instrument is a starting point, the technical problem to be solved in the present invention be to provide a kind of simple in structure, easy to use, measurement result reliable, can from the motion tracking wind direction, can quantitative measurement dust storm flow sand flow monitoring instrument.
For solving the problems of the technologies described above, the technical scheme of taking of the present invention is: a kind of sand flow monitoring instrument, and by the collection sand tube, interior collection Sand Bucket collects Sand Bucket outward, and wind direction guide plate and whirligig are formed; Interior collection Sand Bucket is positioned at outer collection Sand Bucket, outer collection Sand Bucket is equipped with cover plate, the collection sand tube is installed on the cover plate and by whirligig and can rotates flexibly, fixed installation wind direction guide plate on the collection sand tube, the collection sand tube is provided with the air inlet of area definite value, and collection sand tube end opening is positioned at outer collection Sand Bucket and corresponding with the bung of collection Sand Bucket.
For the air that will enter in the instrument inner chamber is in time derived, to reduce the resistance of instrument to wind field, the present invention is equipped with and will be collected the gas outlet that Sand Bucket bucket chamber communicates with atmosphere outward.
The present invention adopts and is absorbed in the sand flow that the target section is passed through in the collection of method principle within a certain height.When needing to measure, the present invention is placed in determined environment, collects Sand Bucket outward and fixedly be embedded in below ground, the collection sand tube stands on more than the ground.When stream occurred, the wind direction guide plate utilized wind-force adjustment collection sand tube, makes air inlet aim at prevailing wind direction all the time.Contain husky air-flow and enter the collection sand tube from air inlet, the grains of sand are subjected to collecting being blocked under the action of gravity of sand tube inwall, along tube wall move downward sedimentation be trapped in in the collection Sand Bucket.The air communication that enters the collection Sand Bucket is crossed gas outlet and is returned atmosphere, has reduced the resistance to air-flow.After one time the stream process finishes, in taking out, outer collection Sand Bucket collects Sand Bucket, pour out sand and measure its weight or volume, because the area of air inlet is that definite value is good, air-admitting surface is converted to unit area, monitoring time is converted to the unit interval, can calculates the sand flow of unit ventilation section in the unit interval.
The present invention has simple in structure, and is easy to operate, little to the wind field resistance, with low cost, measures characteristics such as accurate, can be used for the maintenance monitoring or the mobile monitoring of zones of different stream.

Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
As shown in the figure: a kind of sand flow monitoring instrument, by collection sand tube 4, interior collection Sand Bucket 12 collects Sand Bucket 11 outward, and wind direction guide plate 1 and whirligig are formed; Interior collection Sand Bucket 12 is positioned at outer collection Sand Bucket 11, outer collection Sand Bucket 11 is equipped with cover plate 8, collection sand tube 4 is installed on cover plate 8 and can rotates flexibly by whirligig, fixed installation wind direction guide plate connects folder 2 on the collection sand tube 4, the wind direction guide plate connects folder 2 other ends fixed installation wind direction guide plate 1, collection sand tube 4 is provided with the air inlet 3 of area definite value, and the function of wind direction guide plate 1 is to utilize wind-force to adjust air inlet 3, makes air inlet 3 aim at prevailing wind direction all the time; The air port of wind direction guide plate 1 and air inlet 3 is collected maximum dust storm flow towards being provided with in opposite directions with assurance, collection Sand Bucket 11 and corresponding with the bung of collection Sand Bucket 12 outside collection sand tube 4 end openings are positioned at.
Outer collection Sand Bucket 11 is shells of interior collection Sand Bucket 2 and whirligig, and it plays fixing and supporting role to whole instrument, and interior collection Sand Bucket 12 works to be absorbed in the collection grains of sand.
Collection sand tube of the present invention 4 is made by metal tube, plays conduction stream and rotation axis; It is that 50cm, width are that the rectangle hole of 5mm is as air inlet 3 that the sidewall of present embodiment collection sand tube 4 is provided with a up/down perforation, length; 4 sealings suitable for reading of collection sand tube, end opening is open; The function of collection sand tube 4 is that collecting with air inlet 3 is the stream total flow of collecting section.
The whirligig of present embodiment is fixed on the cover plate 8, and the upper surface of whirligig is concordant with cover plate 8; Whirligig by bearing holder (housing, cover) 6, up and down two bearings 501 and 502, up and down wiper of rubber 901 and 902 and hold-down nut 10 form; Bearing holder (housing, cover) 6 is welded as a whole with cover plate 8; Collection sand tube 4 is contained in the inner ring of two bearings 501 up and down and 502, last wiper of rubber 901 is installed on the outer end of head bearing 501, the central hole of cover plate 8, following wiper of rubber 902 is installed on the outer end of lower bearing 502, hold-down nut 10 is installed in down wiper of rubber 902 outer ends, with upper and lower bearing 501 and 502 and upper and lower wiper of rubber 901 and 902 be plugged in the bearing holder (housing, cover) 6.
