Wind rotating self-lifting sand barrier

Abstract

The invention discloses a wind-driven rotating self-lifting sand-blocking fence, which comprises at least two long vertical poles. The long vertical poles include a long pole body, and a connecting piece is sheathed on the long pole body and slidably connected. The rotary sand control net is connected in rotation, and the rotary sand control net is fixedly connected with at least two outriggers, and the outriggers extend away from the rotary sand control net. The rods are arranged in a straight line. After the wind-driven rotating self-lifting sand barrier has been used for a period of time, the height of the accumulated sand will increase, and the sand surface near the barrier will be raised. During the rotation of the rotary sand control net, the overhanging body collides with the sand surface, generating vibration, which makes the rotary sand control net rise with the elevation of the ground surface, and drives the supporting connectors upward continuously. Avoid the connecting parts being buried by sand, so as to achieve the effect of automatic lifting, and then automatically maintain the purpose of sand prevention effect. The invention is used in the technical field of wind and 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...

AI Technical Summary

Problems solved by technology

[0005] Existing sand-blocking fences are mostly made of plant straw, such as reed fences, etc., and their structures are usually fixed. When the sand-blocking fence is used for a period of time, sand particles gradually accumulate at the bottom of the sand-blocking fence, so that the height of the accumulated sand gradually increases. increase, at this time the effect area of ​​the sand-blocking fence will gradually decrease, and the sand-blocking effect will gradually become weaker.
