Description
Technical field
The utility model relates to a kind of atmospheric environment sand dust monitoring instrument, is specifically related to a kind of near surface stream sediment transport flux long term monitoring system.
Technical background
Near surface stream sediment transport flux is the problem that the research dust storm characteristics of motion and husky district's engineering design must be considered.
Sand-taped instrument is a kind of instrument of monitoring stream, can be divided into active and passive type according to collecting principle, and active be used in the wind-tunnel, passive type is easy to use, is used in a large number more.Up to the present, developed various informative passive type sand-taped instrument.Though occurred a kind of electronic device Sensit Eroding Mass Flux Field Sensor of automatic measurement stream flux at present, it can be measured the moment grains of sand and impinge upon momentum on the probe, and store the quality that momentum obtains clashing into the grains of sand divided by corresponding wind speed.The advantage of this instrument is the observing frequency height, does not need to collect the grains of sand, is fit to very much field inspection.But it is insensitive for less sand grain to pop one's head in, and measurement data is inaccurate, and observation data also must be carried out field-checking with the mechanical type sand-taped instrument simultaneously.Therefore, though also there is such-and-such problem in the mechanical type sand-taped instrument, because the substantivity that it is measured is also used by a large amount of researchers at present.The common problem of mechanical type sand-taped instrument is that majority can not write down the sediment transport process automatically, can only obtain the sediment transport total amount.
Several moneys of following surface analysis are the mechanical type sand-taped instrument of meter certainly:
The variation that tipping bucket type sand-taped instrument (patent No. 01222215.1) calculates the sediment transport flux by the quantity of counter record tipping bucket, measuring accuracy is the weight of a tipping bucket sand, can't more accurately note less wind-sand activity process, even not reflect less wind-sand activity.Simultaneously, the impact that arrives air-flow in the silt container can cause the husky weight of the not enough collection of tipping bucket with regard to overturning once, causes observation data bigger than normal.In addition, this sand-taped instrument can only be collected the sediment transport of a direction.
Dynamic monitor for sand flow (number of patent application 200610043166.7) can be collected the sediment transport of different directions in the corresponding collection Sand Bucket, the Weighing type sensor of collection in the Sand Bucket can perception accumulation sand collecting amount variation, constantly store by will weigh data and corresponding wind speed and direction data of data acquisition system (DAS).But this instrument has following shortcoming: the Chu Sha space is less, is not suitable for long-time field monitoring; The aerial part volume is relatively large, and is bigger to interference in air flow; The gas shock that enters in the collection Sand Bucket can cause the sensor measurement data inaccurate, the suddenly big or suddenly small jump phenomena of data occurs.
The U.S. has developed a kind of Weighing type sand-taped instrument, and it is in BSNE sand-taped instrument sand-collecting slot the Weighing type sensor to be installed, by the long-pending husky accumulating weight data of data acquisition unit collection.But also there are some problems in this sand-taped instrument: in the wind-sand activity, even the grains of sand that enter sand-taped instrument inside are because the internal vortex effect, still be in continuous motion state, the data of weighing can not reflect accurately that sand collecting amount changes, and gas shock simultaneously also causes the record data fluctuation.A kind of Weighing type sand-taped instrument of U.S.'s development, can pass through (
Http:// www.fryreardustsamplers.com/bsne.html) find.
The utility model is at the existing problem that can count the passive type sand-taped instrument certainly, design a kind of little to interference in air flow, exhaust performance good, collect all the direction sediment transports of face of land certain altitude continuously, a kind of Weighing type sediment transport of record accumulation sand collecting amount dynamic changing process is from counting recording geometry automatically.
