I.e. utilizing the wind-power electricity generation collection of energy that dust storm migrates, checking winds and fixing drifting sand that suppression active dune migrates again is dual
Effect.
2. use flexible friction single electrode, with sand dune and the grains of sand as friction object.Existing wind-force triboelectricity
Technology is required for building friction pair, even if single electrode layer is also required to aspectant corresponding frictional layer, this
The cost causing technology increases and the restriction of the condition of use.The present invention makes friction single electrode in the driving of wind-force
Under, while the reduction dust storm rubbed by sandy land surface is migrated so that electrode is charged by friction.This side
Method i.e. decreases the cost of wind-force wind-force triboelectricity device, improve again rubbing device turbulence effects and
Increase the roughness on surface, sand dune, it is not necessary to nanotechnology strengthens generating effect.
3. there is adaptivity, do not destroy ecological environment.The capping of existing sand fixing technology such as surface or geotechnique are husky
The technology such as barrier, owing to being buried by dust storm, it is disposable structures；Simultaneously because by ground, northwest, desert
District's Seasonal Temperature Difference round the clock is big, and sunshine on daytime is strong, and physical weathering and degeneration are aging seriously, institute's consumable material
Easy-weathering corrodes, it is impossible to secondary utilization and the ecological environment to sand ground earth's surface damage.The wind of the present invention
Power triboelectricity device, has adaptivity to wind-driven sediment, sagging contraction under calm condition, is not rising
The protective effect to device is played the when of dust storm.
4. reusing, height adjustable, lower cost for material.Existing sand fixing technology nothing after constructing
Method regulation adapts to the condition that reality dust storm is complicated and changeable.Assembly of the invention is inserted the degree of depth on sand dune and can be adjusted
Joint, under change or wind weakened condition are repaired in sand dune, can extract and be arranged on other desertification areas.Cause
This, the wind-force of the present invention fixes the sand wind-force triboelectricity device, its height adjustable, it is possible to takes out and repeats profit
With, if can significantly save, being laid by mechanized equipment, the cost checked winds and fixed drifting sand.The present invention's
Wind-force wind-force triboelectricity device, monomer volume is little, it is not necessary to use the machinerys such as blade to collect wind energy,
Can set up on active dune surface, with low cost, can large area use.

The present invention is to utilize flexible friction electrode to shake in the gas flow and pat the friction on surface, sand dune, from
And increase air turbulence and sand dune surface roughness, and then the grains of sand are kicked up and quiver by suppression wind-force.By
In wind-driven sediment, sand and dust itself are charged, and when sand and dust and friction electrode collision, it is quiet that its surface is carried
Electricity charge accumulation is on friction electrode, after external force is removed, the electrically charged touched release again of institute, this follows
Reciprocal contact-the separation of ring causes the lasting triboelectrification of electrode and electric discharge, and the Vibrating pulse formula with the wind that formed is produced
Electricity effect.
When increasing considerably the turbulent flow of sand dune airflow on surface, the windward slope surface grains of sand can be substantially reduced and be subject to
Oriented and ordered wind-force migrate, its grains of sand migration can produce chaos disorder phenomenon.Therefore when wind is by sand dune
The turbulent flow produced when the flexible friction electrode on surface blows afloat shake can effectively suppress the migration of the grains of sand.As
