Description
Technical field
This utility model relates to ECOLOGICAL ENVIRONMENTAL MONITORING field, particularly relates to a kind of ice face stream and sediment transport flux of measuring
Rotatable sand-taped instrument.
Background technology
One vital task of Soil Erosion Modelling Study is through silt discharge and changes with height and position, and then determines specific wind
Structure of wind-Sand Flow under the conditions of speed and Sand Flow Transportation shifting amount.Stream is the mass movement of a kind of grains of sand, during being wind-sand activity
Important step, understand the flow behavior of the stream grains of sand, handling process, erosion hazard to prevention soil and water loss, protecting ecology
Environment is significant.
Due to the particularity of environment, the wind-sand activity process of river (such as the Yellow River) bank had both been different from desert, sand ground region,
Also being different from coastal area, after entering comprehensive freezeup period the most in the winter time, the river course water surface becomes ice face, and this period dust storm is lived
Dynamic also into active phase, advance to river course in the way of stream and sand dune reach with the drift sand that ice face contacts, enter ice face husky
Material forms stream on ice face and migrates on ice.So, winter, wind-sand activity related to ice face dust storm process, understood this
Process dust storm is entered river process and enter river amount determination significant, to effectively prevent dust storm enter river provide science theory
Foundation.
Sand-taped instrument be research dust storm movement law, observation Structure of wind-Sand Flow feature and Sand Flow Transportation shifting amount important instrument it
One.At present, most sand-taped instrument is mainly applied to the observation of the field Sand Movements such as desert, sand ground, grassland, farmland.
The sand-taped instrument of current main flow is installed in ice face and measures stream and sediment transport flux, following problem occurs:
1. major part sand-taped instrument is all metal class, and pedestal contacts with ice face, ablation sand-taped instrument meeting after a period of time
Occur or lodging, have influence on the husky effect of receipts, it is impossible to ensure measurement result accuracy and precision.
2. part sand-taped instrument is owing to sand material storage part is at pedestal, and base part is the hugest, takes big on ice face
Hole is installed sand-taped instrument and is difficulty with, and sand-taped instrument base depth can exceed that ice layer thickness causes to install in ice face.
Above-mentioned reason occurs: the pedestal of metal class easily melts on ice face, and thawing speed can be fast；Although winter temperature
In subzero, but metal specific heat holds relatively big with differing of water, heats up very fast, so in nearly noon sand-taped instrument pedestal and ice face
Contact position easily makes ablation so that produces at pedestal and loosens, and causes sand-taped instrument to tilt and lodging.Meanwhile, sand-taped instrument pedestal with
Relatively big the warming with weather winter climate in recent years of upper part weight metal exacerbates the generation of this phenomenon.Warm winter also causes winter in recent years
Ice sheet is thinning, at distribution experiments district ice layer thickness in winter about 30cm, for the hugest sand-taped instrument of those pedestals in ice face
On be difficult to there is place.
The drawback used in ice face for the problem that presently, there are and current sand-taped instrument and limitation, urgent need to develop energy gram
The above difficulty of clothes, is suitable on ice face the sand-taped instrument installed, completes ice face Sand Flow Transportation and move past the observation of journey, enters river observation for dust storm
Effective instrument is provided.This utility model provides a kind of simple in construction, the research ice face dust storm measured accurately, be easily installed
Stream and the rotary type sand-taped instrument of sediment transport flux.
