Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
In arid environments, some biological structures have mist-collecting capabilities, such as conical spines on the cactus stem and spider silk with fusiform processes and node structures. After being captured by the conical structures, the water vapor can spontaneously move to the part with larger radius of the section of the cone and is combined into large water drops, so that the water vapor is collected. This configuration results in more efficient directional movement of the water droplets than other strategies of directional movement of the water droplets, and does not require intervention from an external energy source. Inspired by the structure, the self-cleaning anti-icing composite surface device of the embodiment adopts the composite surface with the bionic structure, and can automatically collect moisture in a humid environment.
As shown in fig. 1 and 2, the self-cleaning anti-icing composite surface device of the embodiment includes a base 1 and a sealing cover 2, wherein the upper surface of the base 1 is provided with a plurality of conical entities 3, the sealing cover 2 is provided with a plurality of sealing ports 4, and the sealing ports 4 are used for penetrating through the conical entities 3; the sealing cover 2 is connected with the base 1, and the conical solid 3 extends out of the surface of the sealing cover 2 from the sealing opening 4; the surface of the sealing cover 2 is provided with a hydrophobic layer, and the surface of the conical entity 3 is provided with a hydrophilic coating.
As shown in fig. 3, the structure of the conical solid 3 includes a column section 31 and a conical section 32, one end of the column section 31 is connected with the base 1, the other end is connected with the conical section 32, the conical section 32 is a conical rotator with a concave side, and the structure of the conical solid 3 extending from the sealing opening 4 to the outside of the surface of the sealing cover 2 is the conical section 32.
The column section 31 as a base may be fixed to the base 1 by welding.
The hydrophilic coating is disposed primarily on the surface of the cone section 32.
The hydrophobic layer and the hydrophilic coating are realized through a surface treatment process, and the hydrophilic coating facilitates automatic collection of water drops on the surface of the hydrophilic conical section 32, so that the water collection effect is improved. Particularly in cold environment, due to the strong hydrophilicity of the surface, the water vapor can be more easily condensed on the cone body 3, and the damage to the surface is avoided. The hydrophobic layer facilitates water drainage when water drops slide down on the surface of the sealing cover 2. And the hydrophobic layer can reduce the adhesion of water drops on the surface in cold environment.
As shown in fig. 4, the tangent of the concave side surface at the vertex of the conical segment 32 forms an angle α with the central axis of the conical segment 32, and preferably α is 10 °.
The side surface of the conical section 32 is concave, which is beneficial to the rapid directional movement of water drops.
Specifically, the tapered entities 3 may be densely arranged on the upper surface of the base 1 in an array. The surface damage caused by the large-area ice layer formed by the accumulation of a large amount of water drops on the surface of the sealing cover 2 is avoided.
A buffer gasket 5 is arranged between the base 1 and the sealing cover 2, and a through hole for the cone-shaped entity 3 to pass through is arranged on the buffer gasket 5.
The buffer gasket 5 is corrugated, the corrugated structure can fill the gap between the base 1 and the sealing cover 2 on one hand, rigid collision to the inside of the structure is avoided, and on the other hand, the surface has a certain buffer energy distance with the base 1 when being collided, so that the overall anti-collision capacity of the composite surface is improved.
And a sealing ring 6 is arranged on the contact surface between the sealing port 4 and the conical solid body 3. The sealing ring 6 plays a role in sealing and buffering.
The base 1 and the sealing cover 2 are positioned and reinforced by fasteners such as bolts 7 and the like.
The working principle of the embodiment is as follows:
the cone-shaped solid body 3 after the surface hydrophilic treatment spontaneously collects water vapor from the environment, and when the collected water vapor is condensed into a water drop with enough size, a certain pressure difference is generated inside the water drop due to the structure of the cone-shaped solid body 3 to promote the water drop to directionally move to the root of the cone-shaped solid body. The principle of directional movement of water drops on the conical solid 3 is shown in fig. 3, when water vapor is collected on the surface of the conical section 32 and reaches a certain specification, water drops are formed and attached to the surface of the conical section, the thick solid line in fig. 3 is the projection of the water drops on the outer contour of the conical surface, and because the conical section has a certain structural gradient, the radius R of the outer contour of the water drops on the projection surface close to the top of the conical bodytipWill be smaller than the radius R of the plane of projection near the root of the coneroot. The pressure inside the drop can be calculated according to the Laplace equation, Δ P ≈ γ (1/R)tip-1/Rroot) Wherein γ is the surface tension of the liquid. As can be seen from the formula, the pressure of the water drop profile near the top of the cone is higher than that near the root of the cone, so that a pressure difference gradient exists inside the water drop attached to the surface of the cone, and the water drop is pushed to directionally move from the solid tip to the root.
The side of the cone section 32 of the conical solid 3 in the embodiment is provided with an inner concave shape, and the inner concave surface has higher transmission efficiency and enables water drops to move faster compared with the conventional cone model through molecular dynamics simulation.
The simulation was performed using the molecular dynamics model shown in FIG. 4, in which the sphere represents a water droplet with a radius r0. The side surfaces of the conical section 32 are concave arcs in cross section. Alpha is the included angle between the tangent line of the concave arc at the vertex of the conical section 32 and the central z-axis of the conical section 32, and alpha represents the concave degree of the side surface of the conical section 32. The smaller alpha is, the smaller the radius of the concave arc is seen from the cross section, namely, the more concave degree is. α -4When the angle is 5 degrees, the radius of the concave arc is infinite, namely the concave degree tends to 0, and the concave arc is converted into a conventional cone.
The included angle between the bottom surface of the cone section 32 and the tangent line in the experimental model is also alpha. For quantitative comparison, the average speed of surface movement of the water droplets in three cases of α ═ 10 °, α ═ 25 °, and α ═ 45 ° was analyzed when the height H of the conical segment 32 was the same. As a result, as shown in fig. 5, the smaller α, the faster the water droplet moves. The water drop is nearly 3 times faster at α 10 ° than at α 45 °.
Since the surface of the sealing cover 2 of the embodiment has hydrophobicity, water drops are difficult to maintain balance on the surface of the sealing cover 2, and slide off the surface under the action of gravity, and meanwhile, dust and impurities on the surface are carried away, so that the self-cleaning function is realized. In order to improve the drainage efficiency, the composite surface is placed at a certain angle during the concrete implementation, and the water drops collected on the hydrophobic surface of the sealing cover 2 can spontaneously slide from the surface under the influence of gravity, so that the drainage function is realized. In cold environments, damage to the surface is mainly due to the accumulation of moisture on the surface forming large or extensive layers of ice that cause the surface to break. For the composite surface of the embodiment, the self-cleaning function exists in the structure, so that the adhesion capacity of water drops on the surface can be reduced, meanwhile, the existence of the array conical entity 3 structure can effectively prevent the water drops from gathering on the wall surface of the sealing cover 2 to form a large-scale ice layer, and meanwhile, the conical entity 3 has a certain reinforcing function on the surface.
The self-cleaning anti-icing composite surface device of the embodiment can realize the functions of self cleaning and anti-icing without accessing external energy.
