AI Technical Summary
Existing sand control and afforestation enclosure devices, while reducing airflow through flexible panels designed to lower wind speed, increase wind speed through the holes, causing sand and dust to be carried further away, thus affecting the effectiveness of sand control and afforestation.
A enclosure device with a wind guide plate and a fan-shaped flexible membrane was designed. The wind guide plate can be rotated by a rotating shaft, and the fan-shaped flexible membrane limits the angle of the wind guide plate, guiding the sand and dust downwards. Combined with the top sand and dust guide plate, a wind wall is formed to prevent sand and dust from being blown far away.
It effectively slows down the process of desertification by diverting wind and sand to settle near the enclosure, thus preventing the spread of sand and enhancing the effect of sand prevention and control.
