Self-driven planar fog droplet directional collecting structure
The invention belongs to the technical field of fog droplet collection, and discloses a self-driven planar fog droplet directional collecting structure. At least one fog collecting unit with hydrophobic or super-hydrophobic surfaces is arranged. The fog collecting units comprise ridge parts and fog collecting sheets which are arranged on the same plane. The multiple fog collecting sheets are connected to the ridge parts and further extend outwards to the two sides from the ridge parts. Each fog collecting sheet comprises at least one outer side tip end and can achieve even transition to the outer side tip end from a corresponding inner side root part. The fog collecting sheets are used for collecting droplets and further directionally conveying the droplets to the ridge parts under the driving action of Laplace pressure. The ridge parts are used for making the droplets move directionally in the length direction under the gravity driving action. According to the self-driven planar fog droplet directional collecting structure, the planar structure mode is adopted, the asymmetrical Laplace pressure and gravity are used for driving, the spontaneous capturing and spontaneous driving directional fog collecting process is completed , and thus the purposes of autonomous fog collection and self-directional conveyance are achieved; and the structure is simple, manufacturing is easy, costis low and the self-driven planar fog droplet directional collecting structure is expected to be put into use on a large scale.
本发明属于雾气液滴收集技术领域，公开了一种自驱动的平面化雾气液滴定向收集结构，至少一个具有疏水或超疏水表面的集雾单元；集雾单元包括在同平面设置的脊部和集雾片，多个集雾片连接于脊部并由脊部向两侧外伸，每个集雾片包括至少一个外侧尖端，且均由内侧根部向外侧尖端均匀过渡；集雾片用于收集液滴并使液滴在拉普拉斯压的驱动下定向输运至脊部，脊部用于使液滴在重力驱动下沿其长度方向定向运动。本发明采用平面化的结构形式，利用不对称拉普拉斯压和重力驱动，实现自发捕捉和自发驱动的定向集雾过程，从而实现自主收集雾气并自行定向输运的目的，结构简单，易于制造，成本低廉并且有望大规模投入使用。
