Wind-power rotation automatic lifting type high sand break palisade

Abstract

The invention discloses a wind-power rotation automatic lifting type high sand break palisade which comprises at least two long vertical rods. Each long vertical rod comprises a long rod body; a connecting piece sleeves and is slidably connected onto each long rod body; a rotation type sand-prevention mesh is rotatably connected between each two adjacent connecting pieces and is fixedly connectedwith at least two stretching bodies; the stretching bodies extend toward the normal direction far away from the rotation type sand-prevention mesh; and a plurality of stretching bodies are linearly arranged between the two adjacent long vertical rods. After the wind-power rotation automatic lifting type high sand break palisade is used for a period, the height of deposited sand is increased, and asand level near the palisade can be elevated at the moment. In the rotation process of the rotation type sand-prevention mesh, the stretching bodies hit against the sand level so as to produce a vibration effect, the rotation type sand-prevention mesh is elevated along with the elevation of the earth surface, and the connecting pieces playing a role in supporting are driven to go up constantly soas to be prevented from being buried by sand grains, so that an automatic elevating effect is achieved, and the aim on automatically keeping a sand prevention effect is further achieved. The wind-power rotation automatic lifting type high sand break palisade provided by the invention is applied to the technical field of wind-blown sand prevention and control.

Description

technical field [0001] The invention relates to the technical field of wind and sand prevention and control, in particular to a wind-driven rotating and automatically lifting sand-blocking fence. Background technique [0002] About one-third of the earth's land is arid or semi-arid, and there are often sandstorms in the latter areas, including deserts and Gobi. With the destruction of the ecological environment, land desertification is becoming more and more serious, resulting in more and more wind and sand disasters. Sandstorm disasters can not only bury crops, erode soil, reduce soil fertility, etc., but also damage infrastructure such as roads and railways. Especially in the Gobi area, wind and sand prevention is even more important. [0003] Sandstorm disasters in the Gobi region are characterized by high wind speed, strong energy, and high bouncing of sand particles. Sandstorm disasters are more harmful than those in ordinary desert areas. Under the condition of high...
