Problems solved by technology

[0003] In the prior art, in order to improve the solar photovoltaic glass curtain wall’s transmittance of sunlight and the generation rate of solar energy, the solar photovoltaic cells are installed obliquely, but in this installation method, the glass curtain wall of the same area will consume more The solar cells have greatly increased the application cost of solar photovoltaic glass curtain walls. At the same time, with the increase in the application of solar photovoltaic glass curtain walls, solar photovoltaic glass curtain walls have become "migratory bird killers", and migratory birds are injured when they hit the glass curtain wall. or die at the same time, the frequent impact on the glass curtain wall greatly reduces the stability of the glass curtain wall installation and causes the glass to explode

Embodiment 1

[0029] Embodiment one: refer to Figure 1-Figure 7 , a solar photovoltaic glass curtain wall, including an aluminum alloy outer frame 1, a back glass 2 and a low-iron glass 4, the front side of the low-iron glass 4 is equipped with a micro-deformable and light-transmitting outer protective plate 3, an aluminum alloy The inner sides of the upper and lower ends of the outer frame 1 are provided with end card slots 11, the back glass 2 and the low-iron glass 4 are arranged in the aluminum alloy outer frame 1, and the upper and lower ends of the back glass 2 and the low-iron glass 4 are respectively provided with snap-in slots. The end connection card board 6 in the end card slot 11, the side of the back glass 2 close to the low-iron glass 4 is provided with a plurality of solar cell installation slots 21 and a plurality of cable installation slots 22, so as to ensure that the sunlight is irradiated outside. After the protective plate 3 is on, it can be irradiated on the solar cel...

Embodiment 2

[0031] refer to Figure 1-Figure 7 , a solar photovoltaic glass curtain wall, the difference between this embodiment and Embodiment 1 is:

[0032] The outer protective plate 3 is provided with a plurality of light guide holes 31 penetrating through its inner and outer surfaces, and an installation gap is provided between the outer protective plate 3 and the low-iron glass 4, and solar energy enters the installation gap 5 through the light guide holes 31. The light energy in the light guide holes 31 is collected in the installation gap 5 and then irradiated on the solar cell sheet in the solar cell sheet installation groove 21 through the low-iron glass 4, so that the solar energy is utilized more fully. Further, when the strong wind blows During this device, the wind enters the installation gap 5 through the light guide hole 31, and then is exported through the light guide hole 31, thereby effectively reducing the wind force on the outer protective plate 3 and improving the st...

Embodiment 3

[0034] refer to Figure 1-Figure 7 , a solar photovoltaic glass curtain wall. The difference between this embodiment and Embodiment 1 or 2 is that: the upper and lower ends of the back glass 2 are provided with isolation plates 23 on the side close to the low-iron glass 4, and the upper and lower ends of the low-iron glass 4 The position opposite to the isolation plate 23 is provided with an isolation groove 41, and the end of the isolation plate 23 away from the back glass 2 is clamped in the isolation groove 41. The front side of the solar cell is not in contact with the low-iron glass 4, and at the same time, a light-transmitting gap is formed between the low-iron glass 4 and the solar cell and the low-iron glass 4 to ensure more light transmittance, thereby generating more electric energy .

Abstract

The invention discloses a solar photovoltaic glass curtain wall which comprises an aluminum alloy outer frame, back side glass and low iron glass. A nonopaque outer protecting plate capable of deforming finely is mounted on the side, deviated from the back side glass, of the low iron glass. According to the solar photovoltaic glass curtain wall, in a process that sunlight irradiating on the outerprotecting plate is absorbed by a solar battery piece by penetrating through the outer protecting plate and the low iron glass, it is ensured that solar energies at different irradiation angles can penetrate through the outer protecting plate and the low iron glass and then irradiate to the solar battery piece, so that the electric energy is generated to the maximum extent while the solar ray transmittance is guaranteed. Meanwhile, a buffer air chamber is formed in a mounting gap while the outer protecting plate is extruded passively to deform finely, so that conditions that migrant birds hitting against the outer protecting plate are dead as a result of an excessive impact force and the glass curtain wall formed by the outer protecting plate, the low iron glass and the back side glass andthe like is unstable as the outer protecting plate is hit are prevented.

Description

technical field [0001] The invention relates to the technical field of glass curtain walls, in particular to a solar photovoltaic glass curtain wall. Background technique [0002] Solar photovoltaic glass is a special glass that is laminated into solar cells, can use solar radiation to generate electricity, and has related current extraction devices and cables. It is composed of low-iron glass, solar cell, film, back glass, and special metal wires. The solar cell is sealed between a piece of low-iron glass and a piece of back glass through the film. It is the most innovative high-tech building. Glass products, with the advancement of science and technology, solar photovoltaic glass curtain walls are now widely used. [0003] In the prior art, in order to improve the solar photovoltaic glass curtain wall’s transmittance of sunlight and the generation rate of solar energy, the solar photovoltaic cells are installed obliquely, but in this installation method, the glass curtain...
