Technical field
The utility model relates to soil environment field, specifically a kind of different gradient soil drifting amount suitable for wind-tunnel
Automatic measuring instrument.
Background technique
Desertification is the serious environmental problem that our times faces.The every annual in the whole world has (5 ~ 7) × 104km2
Soil becomes desertification land, there is nearly 100 countries and regions, threat of 8.5 hundred million populations by desertification.In China, desert
Change soil also to expand 2370km every year on average2Speed development.In order to formulate the effective measures of prevention and treatment desertification, just need
There are the formation for illustrating wind-driven sediment and eolian landform form, law of development, and the blown sand physics and dust storm that prevent and control sandy storm
The theory and method of engineering science is as guidance.Wind tunnel experiment tests the important component as wind-driven sediment, is research wind
The important means of husky kinematics development, in wind-driven sediment many rules and theory be all found on the basis of wind tunnel experiment with
It obtains.Meanwhile wind tunnel experiment is also the foundation for verifying wind-driven sediment theory and calculated result correctness.
Desertification is exactly a wind erosion problem after all.Soil drifting is not only the important component of desertification, and
It and is primary link.Soil drifting is not only the important component of desertification, and is primary link.Come in a sense
It says, not eroding just, there is no hazards of sand storms problems.Wind erosion is a kind of power mechanism of atmosphere Yu loose sandy soil earth's surface.It
Husky and soil in earth's surface is played into the deflation carried and terrestrial materials by two kinds of stream impact and the abrasion to rub etc. including wind
Effect.Wind erosion causes the soil losses of earth's surface, surface soil roughening, soil fertility sharply to decline, and then drift sand geomorphologic landscape occur.Wind erosion is also
It can produce the aerosol particle for being largely suspended in atmosphere, directly the space of the mankind and biological existence polluted, influences people
Class health and lives safety.
Currently, carry out soil drifting problem research, generally use two kinds of means: first is that naturally wind erosion under the conditions of into
The field of row wind speed and dust storm Transport Law directly observes and measures.Since natural conditions are intricate, ground table status is multifarious,
So that directly observing by field to study soil drifting, many unexpected difficulties have been encountered；Second is that utilizing Modern air
Mechanics experimental apparatus-blowing sand wind tunnel carries out the experiment analog study of soil drifting process.Using indoor wind sand environment
Wind- tunnel investigation, wind are by wind tunnel simulation, and underlying surface earth's surface to be measured is that imagineering is formed.This method can be with people
To control required the test wind, field inspection needs several years test datas that could be completed, indoors some months in wind-tunnel
It can be obtained by experiment.Under normal circumstances, soil drifting amount needs passing through the deflation of different size wind speed respectively with laggard
Row is weighed so that wind erosion efficiency is calculated, but is being carried, easily caused soil model structural damage in weighing process, so that
Soil texture collected generates unstability, to make the generation error of experimental result.
Utility model content
In conclusion making up present wind to reduce various errors caused by human factor during measurement soil drifting
Hole soil drifting measurement is unable to the deficiency of automatic measurement soil drifting amount, the utility model provide it is a kind of suitable for wind-tunnel not
With gradient soil drifting amount automatic measuring instrument, field soil characteristic and surface roughness and its original can be protected to greatest extent
Gradient feature reduces the transformed error between the human factor and each measuring instrument in measurement process, so that automatic collection measures
Soil drifting amount, effectively accurately to prevent soil sandification research from providing the data of scientific and precise.
The utility model utility model solves technical solution used by its technical problem:
