[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0027] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] like Figs. 1-6 As shown, the meanings of the various marks are as follows: glass panel 1, super hydrophilic coating 2, keel support frame 3, annular base 4, card slot 41, first card hole 42, elastic protrusion 43, elastic frame 5, long strip 51, horizontal strip 52, elastic protrusion 53, clearance hole 54, annular card seat 6, second card hole 61.

[0029] like Figs. 1-6 As shown, the present invention provides a glass curtain wall, comprising a plurality of glass main body units, each of which comprises:

[0030] A glass panel 1 has a wavy cross-section along the vertical direction on its outer surface, and a super-hydrophilic coating 2 is applied on the outer surface of the glass panel 1; the super-hydrophilic coating 2 is formed by applying a super-hydrophilic material, and the super-hydrophilic coating 2 can be a dioxyde peptide film or a modified dioxyde peptide film. When the contact angle between the super-hydrophilic coating 2 and the water droplet is less than 5°, the water droplet contacts the glass plate to form a uniform water film on the surface of the glass plate, and the water film can take away dust and pollutants on the surface of the glass plate. After testing the particle size of dust in the environment of this region (Sri Lanka, Hambantota International Airport), it was found that the particle size of the dust is 10 -6 The dust particles of this size account for more than 80%, and it has been calculated that the adhesion forces between the dust particles of this size and the glass panel 1 are mainly van der Waals force, gravity and electrostatic force, and the magnitudes of these three forces are 10 -9 , 10 -9 , 10 -12Therefore, the water droplets can be taken away from the surface of the glass panel 1. Since the glass panel 1 is usually vertically arranged, the contact time of the water droplets with the glass panel 1 is short, which affects the dust cleaning speed. Therefore, the surface of the glass panel 1 is arranged in a wave shape, so as to prolong the contact time of the water droplets with the glass panel 1, and the cleaning degree can be significantly improved. Although the wave shape also has the disadvantage of trapping more dust and pollutants, compared with the wave shape, the cleaning effect of the water droplets is stronger.

[0031] The keel support frame 3 is internally circumferentially provided with an annular elastic mechanism, and the glass panel 1 is circumferentially clamped and fixed in the elastic mechanism. Although the super-hydrophilic coating 2 has the self-cleaning performance, it also has the disadvantage that when the wind and sand are too large, the super-hydrophilic coating 2 is easily damaged irreversibly, thereby affecting the self-cleaning ability. Therefore, by arranging the elastic mechanism and fixing the glass panel 1 on the elastic mechanism, when the glass panel 1 is subjected to external force, the glass panel 1 can be slightly displaced, thereby relieving the effect of the wind and sand. On the other hand, the wave-shaped appearance also has the effect of guiding the flow of wind and reducing the damage of the wind and sand to the super-hydrophilic coating 2.

[0032] In the above technical solution, the cleaning of the glass curtain wall has always been a difficult technical problem to solve. The glass curtain wall has a large area and is located on the outer facade. When cleaning, the safety hidden danger is large, and the cleaning cost is high. The glass curtain wall of the present application adopts the super-hydrophilic coating 2, which can realize self-cleaning, thereby significantly reducing the cleaning and maintenance cost. The present application arranges the wave shape to prolong the contact time of the water droplets with the glass panel 1, which can significantly improve the cleaning degree. Although the wave shape also has the disadvantage of trapping more dust and pollutants, compared with the wave shape, the cleaning effect of the water droplets is stronger. By arranging the elastic mechanism and fixing the glass panel 1 on the elastic mechanism, when the glass panel 1 is subjected to external force, the glass panel 1 can be slightly displaced, thereby relieving the effect of the wind and sand.

[0033] In another technical solution, the elastic mechanism comprises:

[0034] The annular base 4 is arranged on the inner wall of the keel support frame 3. A plurality of annular clamping grooves 41 are circumferentially arranged in the middle of the annular base 4. A plurality of first clamping holes 42 are circumferentially arranged on the bottom surface of the clamping grooves 41. A plurality of elastic protruding columns 43 are circumferentially arranged on the surface of the annular base 4. The elastic protruding columns 43 are made of a rubber material with high elasticity.

[0035] A plurality of elastic frames 5, a plurality of elastic frames 5 are correspondingly arranged in a plurality of clamping grooves 41, each elastic frame 5 comprises a long strip plate 51 clamped in the clamping groove 41, a plurality of transverse strip plates 52 are hingedly connected to the long strip plate 51, a pair of elastic lugs 53 are sleeved on the transverse strip plate 52, wherein the transverse strip plate 52 is provided with a clearance hole 54 at both ends, the clearance hole 54 is sleeved on the elastic lug 43, and the lower end of the elastic lug 53 is clamped in the first clamping hole 42; the elastic frame 5 is a main component for providing buffer displacement, and the elastic frame 5 is also an intermediate component for connecting the annular base 4 and the annular clamping seat 6, and the elastic lug 53 is made of a rubber material with high elasticity. The elastic frame 5 is formed by the elastic lug 43 and the clearance hole 54 once, and is formed by the elastic lug 53 and the first clamping hole 42 twice, so that the elastic frame 5 and the annular base 4 are reliably connected in an elastic manner.

[0036] The annular clamping seat 6 is provided with a plurality of second clamping holes 61 on the bottom surface in a circumferential direction, the elastic lug 53 is clamped in the second clamping hole 61, and the annular clamping seat 6 is clamped in the circumferential direction of the glass panel 1. The elastic frame 5 is connected to the second clamping hole 61 through the elastic lug 53, so that the annular clamping seat 6 and the elastic frame 5 are reliably connected in an elastic manner. Then the glass panel 1 is wrapped in the annular clamping seat 6 in the circumferential direction, the glass panel 1 is fixed, and the elastic supporting force of the elastic frame 5 is transmitted to the glass panel 1, so as to protect the glass panel 1.

[0037] In the above technical solution, the annular base 4, the elastic frame 5 and the annular clamping seat 6 are connected and fixed with the keel support frame 3, then can be connected and fixed with the glass panel 1, and form a three-dimensional reliable elastic structure for supporting the glass panel 1, protecting the glass panel 1, reducing the impact force of wind and sand on the glass panel 1, thereby protecting the super-hydrophilic coating 2 on the surface of the glass panel 1. Compared with the existing technology, the spring is more reliable and has more three-dimensional elastic expansion. The airport is mainly located in an open environment, and the glass curtain wall of the terminal building is not only affected by natural wind, but also often affected by air flow caused by take-off and landing of aircraft. Therefore, the above-mentioned elastic structure designed for the glass panel 1 of the terminal building can more effectively reduce the impact force of air flow on the glass panel 1 and protect the glass panel 1.

[0038] In another technical solution, the wave shape is a cosine function graph, the amplitude is 0.5-1mm, and the length of one period is 2-5mm. According to the water droplet diameter of 1-200μm, a period length of 2-5mm can accommodate water droplets, and under the action of the super-hydrophilic coating 2, the water droplets can form a water film to carry away dust and improve dust removal capacity.

[0039] In another technical solution, the clamping groove 41 and the elastic protrusion 53 are both flat cuboids. The clamping is more stable and reliable.

[0040] In another technical solution, the glass panel 1 is flat cuboid, the number of the clamping grooves 41 is four, and they are evenly arranged on the four inner side walls of the ring-shaped base 4 respectively. The existing glass panel 1, whether double-layer or single-layer, is mostly cuboid. And being arranged on the four side walls respectively, a structure with elastic support on four sides can be formed, improving the buffering capacity.

[0041] In another technical solution, the distance between two adjacent horizontal strip plates 52 is 5-8 cm. The elastic support is more reliable, and the amount of suspension is reduced.

[0042] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be fully applied to various fields suitable for the present application, and other modifications can be easily realized by those skilled in the art, and therefore the present application is not limited to specific details and the figures shown and described herein.
