Description

Glass curtain wall

Technical Field

The invention relates to the technical field of curtain walls, in particular to a glass curtain wall.

Background

The atomization of the glass means that water vapor in the air reaches a saturated state when being cooled to the dew point, and is condensed on the surface of a glass product to form tiny droplets, and the droplets refract and scatter light rays to cause the opaque phenomenon of the glass.

In modern building buildings, in order to increase the aesthetic degree of the buildings, large and even huge glass curtain walls are selected as light transmission windows for more and more buildings, and the accompanying problem is that obvious water mist can be generated when the temperature difference between the indoor and outdoor is large and the relative humidity of the environment is large, so that the aesthetic degree of the buildings is greatly reduced, and because a lot of water mist is in the high altitude and outdoor, the difficulty of manual demisting is large, the existing glass curtain walls are very prone to being scratched in the building industry.

Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-2, a glass curtain wall comprises a square glass plate 1, the glass plate 1 is fixed on an external frame body through a U-shaped frame 2, a plurality of capillary holes 3 and ball bins 4 are equidistantly arranged on the glass plate 1, each capillary hole 3 is communicated with one ball bin 4, the opening end of the capillary hole 3 on the inner wall of each ball bin 4 is fixed with a mirror surface seat 5, the contact part of the mirror surface seat 5 and the inner wall of each ball bin 4 is provided with a mirror surface, the mirror surface on the mirror surface seat 5 can completely reflect light irradiating the contact surface of the mirror surface seat 5 and the ball bins, an expansion ball 6 is fixed on the mirror surface seat 5, a plurality of lasers 7 pointing to the other side are fixed on one side of the glass plate 1, and a plurality of receivers 8 capable of receiving the laser are fixed on the other side of the glass plate 1;

the central angle range of the section of the ball bin 4 is 270-300 degrees, the phenomenon of total reflection can be generated when laser irradiates the interface surface of glass and air on the inner wall of the ball bin, and the glass plate 1 is made of optical quartz glass. The expansion ball 6 is prepared by mixing starch, acrylonitrile and acrylate according to the ratio of 2:3:2, and the laser 7 can emit laser with the wavelength of 185 nm.

In the glass curtain wall, when the glass curtain wall is in a normal fog-free environment, the laser 7 emits laser with lower power, the angle of the laser 7 is adjusted to enable the emitted laser to irradiate the boundary angle between the glass plate 1 and the air to be more than 40 degrees, tests show that the refractive index of quartz glass to the laser with the wavelength of 185nm is 1.57456, namely the critical angle of the quartz glass to the glass plate 1 and the air is 39.425 degrees, and total reflection can be generated when the incident angle is more than the critical angle, so that in the glass curtain wall, the light emitted by the laser 7 irradiates the boundary surface between the glass curtain wall 1 and the air for multiple times and is totally reflected until the light irradiates a receiver 8 on the other side of the laser 7, and the receiver 8 can stably receive the laser with certain power under the fog-free; it is worth to be noted that when the laser irradiates the boundary surface between the glass and the air in the ball bin 4, the incident angle is larger than the critical angle to generate total reflection, and when the laser irradiates the boundary surface between the mirror seat 5 and the glass, the mirror seat 5 is processed with a mirror surface, so that the laser can also generate total reflection, thereby ensuring that the receiver 8 receives the laser with stable power, and in a fog-free environment, the laser cannot be emitted from a glass curtain wall to affect the outside;

when fog is generated on the glass curtain wall, because the fog is essentially liquid water drops, when the fog is attached to the capillary holes 3 on the glass curtain wall 1, the fog can generate a capillary effect under the action of the surface tension of water and enter the capillary holes 3, and the expansion ball 6 can expand in a short time after contacting with the water until contacting with the ball bin 4; through measurement and calculation, the refractive index of a sphere prepared by mixing starch, acrylonitrile and acrylate according to the ratio of 2:3:2 after absorption and expansion is 1.25-1.67, so that the critical angle between the expansion ball 6 and the inner wall of the ball bin 4 is large (when the refractive index of the expansion ball 6 is larger than that of quartz glass, laser irradiates from the glass to the expansion ball 6 from an optically thinner medium to an optically denser medium, and the total reflection phenomenon does not exist). Therefore, the laser irradiated on the surface of the inner bin 4 can be reflected and refracted, a part of the laser can be irradiated into the expansion ball 6, the expansion ball 6 is not completely transparent, the incident laser can be quickly weakened, the energy of the laser can be absorbed by the expansion ball 6 and converted into heat to heat the expansion ball, meanwhile, the unabsorbed laser in the expansion ball 6 is irradiated to the interface surface of the expansion ball 6 and air or water to be totally reflected back into the expansion ball 6 again, a small amount of laser can be irradiated to the interface surface of the expansion ball 6 and glass to be weakened again through the double effects of reflection and refraction until the energy of the laser is completely absorbed by the expansion ball 6 and heated.

When fog vapor appears on the glass curtain wall, the expansion ball 6 expands and absorbs part of laser to convert the laser into heat energy, so that the glass around the expansion ball 6 is heated, the evaporation speed of the fog vapor on the glass plate 1 is accelerated, and the anti-fog effect is realized; when the expansion ball 6 absorbs the laser, the power of the laser received by the receiver 8 is also obviously reduced, and the evaporation speed of the mist can be accelerated by increasing the power of the laser.

In the invention, at the initial stage of condensing the mist on the glass curtain wall, the expansion ball 6 at the corresponding position generates heat to evaporate the mist, so that the mist cannot be further condensed, thereby realizing the effect of demisting and having good antifogging effect.

Although the terms glass plate 1, U-shaped frame 2, capillary 3, ball magazine 4, mirror mount 5, expansion ball 6, laser 7, receiver 8, etc. are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
