AI Technical Summary

Technical Problem

Traditional greenhouse ventilation systems have fixed ventilation locations, making it difficult to adjust them flexibly according to actual needs. This can lead to sudden drops in temperature in the morning or the inability to effectively expel hot and humid air at noon, affecting vegetable growth and yield.

Method used

A ventilation device comprising a cover and a guide tube was designed. The guide tube is rotatably connected and its free end height is adjustable. Combined with a drive motor and fan blades, the ventilation direction and range can be flexibly adjusted.

Benefits of technology

By flexibly adjusting the direction and range of ventilation, sudden drops in cold air can be avoided, improving ventilation efficiency, meeting the growth needs of vegetables at different times, and increasing yield and quality.
