Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-4 As shown, this utility model proposes an embodiment of a high weather-resistant photovoltaic module coated glass, comprising: a flat glass 1, with a polarizing film 2 attached to the bottom of the flat glass 1.

[0036] Transition film 6 is coated on the surface of flat glass 1. The material of transition film 6 is silicon dioxide. Since the material of transition film is silicon dioxide, it has strong corrosion resistance and light transmission, which improves the weather resistance of glass.

[0037] The radiation shielding film 7 is coated on the surface of the transition film 6 to isolate radiation and improve the radiation resistance of the installation environment.

[0038] Support layer 3 is bonded to polarizing film 2. Support layer 3 is divided into transverse light-transmitting strips 301 and longitudinal light-transmitting strips 302. The transverse light-transmitting strips 301 and longitudinal light-transmitting strips 302 are staggered, which greatly enhances the strength of the glass and improves its durability.

[0039] Insulation layer 8 is attached to the bottom of support layer 3, which improves the insulation effect of the glass.

[0040] PVB adhesive layer 9 bonds the insulation layer 8 to the convex interlayer 4.

[0041] The convex interlayer 4 is located between the two support layers 3. When light shines on the glass surface, it is refracted by the polarizing film 2. The light then undergoes further refraction and reflection through the convex interlayer 4, which greatly avoids direct light and improves the comfort of the user environment. At the same time, since the two convex interlayers 4 are bonded together, the strength of the glass is further improved and the service life of the glass is extended.

[0042] Adhesive penetration holes 10 are formed on the surface of the convex interlayer 4 and located in the recessed position of the convex interlayer 4. The two convex interlayers 4 are bonded together in opposite directions, so that the adhesive can penetrate into the gap between the two convex interlayers 4 through the adhesive penetration holes 10, ensuring the stability of the bonding.

[0043] A limiting frame 5 is placed on the surface of the convex interlayer 4. Both the convex interlayer 4 and the limiting frame 5 are made of light-transmitting material. The limiting frame 5 limits the convex interlayer 4 to ensure the alignment of the two convex interlayers 4 when they are bonded together, and to prevent the two convex interlayers 4 from shifting during production.

[0044] The adhesive guide groove 11 is located on the top of the limiting frame 5.

[0045] The glue discharge hole 12 is located on the inner wall of the limiting frame 5 and is connected to the glue guide groove 11. Glue is poured into the glue guide groove 11 and seeps out through the glue discharge hole 12 to fill the gap between the convex interlayer 4 and the limiting frame 5, ensuring that the gap between the convex interlayer 4 and the limiting frame 5 is filled with glue and ensuring the stability of the bonding.

[0046] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0047] This utility model provides a high weather-resistant coated glass for photovoltaic modules. When light shines on the glass surface, it is refracted by the polarizing film 2. The light then undergoes further refraction and reflection through the convex surface of the convex interlayer 4. The transverse light-transmitting strips 301 and longitudinal light-transmitting strips 302 are staggered, which greatly enhances the strength of the glass. Under the action of the transition film 6 and the anti-radiation film 7, the corrosion resistance and radiation protection of the glass are improved.

[0048] In summary, this type of high weather-resistant photovoltaic module coated glass, through the cooperation of flat glass 1, polarizing film 2, support layer 3, convex interlayer 4 and limiting frame 5, solves the problems mentioned in the background art.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
