Self-driven planar fog droplet directional collecting structure

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of mist droplet collection, and in particular relates to a functional structure for collecting and transporting tiny mist droplets. Background technique [0002] Fog water collection is considered to be an effective solution to the problem of water collection for people in poor and arid areas. Among the efficient methods of fog water collection, learning from nature and using bionic technology has proved to be a more efficient path. The combined hydrophobic / hydrophilic patterned surface inspired by the desert beetle and the cone-spine array learned from the cactus represent two typical bioinspired ways of fog water collection. After first demonstrating the unique fog water collection ability, artificial fog collectors inspired by cacti based on metal spines, integrated structures, etc. have been widely reported. In these systems, the directional transport of accumulated droplets is highly dependent on wetta...
