Problems solved by technology

Regarding the application of geometric gradients in fog collection, there are currently only concave-convex surfaces represented by the Namib desert beetle, cone-shaped drive structures represented by cactus spikes, pine needles, spider silk, etc., and further simplified wedge-shaped structures, which greatly restricts the application of geometric gradients in fog collection. Improved droplet transport efficiency

specific Embodiment 1

[0025] A structure that uses carving techniques for efficient water collection, such as figure 1 As shown, including the stainless steel sheet 1, the stainless steel sheet 1 is provided with 3 slits 2 at equal intervals horizontally (at least 3, shown as 3 in the figure), and the stainless steel sheet 1 is provided with 8 slits 2 at equal intervals in the longitudinal direction (at least 8, The figure shows 8 lines), the upper and lower adjacent gaps 2 are arranged alternately, and the middle of each gap 2 is provided with a water drop collection hole 3, and the distance between the water drop collection hole 3 and the gap 2 directly below is smaller than that of the upper and lower adjacent gaps 2 Longitudinal spacing, the side of the stainless steel sheet 1 facing the mist is set as a hydrophobic surface and the other side is provided with a hydrophilic surface, the stainless steel sheet 1 is stretched longitudinally until each gap 2 is fully opened, and the stainless steel s...

specific Embodiment 2

[0031] A method for efficient water collection using a specific embodiment of a carving process for efficient water collection, such as figure 1 shown, including the following steps:

[0032] (1) Turn the hydrophobic surface of the stainless steel sheet 1 toward the direction of the mist source, and the mist condenses on the hydrophobic panel to form tiny drops of water, clamp the stainless steel sheet 1 with the clamper 4, and stretch the stainless steel sheet 1 longitudinally to make each gap 2 completely Opening, the stainless steel sheet 1 is deformed to form a horizontal simple harmonic structure. Driven by the curvature gradient of the stainless steel sheet 1 itself, the water droplets move to the water drop collection hole 3 in the center of the corrugated plate depression, and gradually coalesce and become larger during the movement , leaving a dry hydrophobic surface for further condensation of water droplets;

[0033] (2) When the enriched water droplets touch the w...

Abstract

The structure is characterized in that the structure comprises a stainless steel thin plate, at least three gaps are horizontally formed in the stainless steel thin plate at equal intervals, at least eight gaps are longitudinally formed in the stainless steel thin plate at equal intervals, and the vertically adjacent gaps are arranged in a staggered mode; a water drop collecting hole is formed over the middle of each gap, the distance between the water drop collecting hole and the gap under the water drop collecting hole is smaller than the longitudinal distance between the upper gap and the lower gap, the side, facing mist, of the stainless steel thin plate is arranged to be a hydrophobic face, and the other side of the stainless steel thin plate is provided with a hydrophilic face; the stainless steel thin plate deforms to form a horizontal simple harmonic structure capable of driving the liquid drops on the stainless steel thin plate to automatically move towards the water drop collecting holes. The water collecting device has the advantages of high water collecting efficiency, simple structure, no maintenance and no energy consumption.

Description

technical field [0001] The invention relates to the field of water collection, in particular to a structure and method for efficiently collecting water by using engraving technology. Background technique [0002] With the continuous increase of the global population, the shortage of fresh water resources has begun to seriously threaten the sustainable development of human society, and even two-thirds of the world's population is facing serious water shortages. Compared with high-energy desalination or high-investment water diversion projects, mist trapping and water collection have attracted widespread attention because they are not limited by terrain and cost. This process mainly includes the nucleation and removal of water droplets. In order to increase the nucleation speed, it can be The design of the surface microstructure provides a large number of nucleation sites for the growth of droplets. If the growing droplets are not removed in time, a liquid film will be formed...
