[0031] As Figure 1 and Figure 2 shown, this embodiment provides a heat-insulating photovoltaic module, which includes a photovoltaic glass 10, connecting purlins 20, and a supporting backboard 30; multiple connecting purlins 20 are arranged in parallel on the supporting backboard 30, and multiple photovoltaic glasses 10 are connected to the multiple connecting purlins 20; the photovoltaic glass 10 includes a power generation glass layer 11, a first intermediate film 12, and a vacuum glass layer 13; the power generation glass layer 11, the first intermediate film 12, and the vacuum glass layer 13 are connected in sequence from top to bottom, and the vacuum glass layer 13 is connected to the connecting purlin 20.

[0032] By adopting the photovoltaic glass 10 with a vacuum structure in this embodiment, the problems of infrared heat insulation and heat conduction heat insulation are effectively solved. Compared with the prior art, this structure enables the power generation glass layer 11 to effectively handle the heat insulation problem even when it is opaque, greatly improving the heat insulation performance of the photovoltaic glass 10.

[0033] In addition, the power generation glass can generate electricity, and the generated electricity can be provided to the building for use through the system; the vacuum glass layer 13 has good heat insulation performance. When the two are combined into one and form a building envelope structure, it is a product that combines energy empowerment and energy conservation. It uses the method of vacuum medium isolation for heat insulation. Compared with the hollow structure, it has less reflectivity during use and will not cause light pollution. Secondly, after the vacuum glass layer 13 is combined with the power generation glass, it can solve the technical problems of light spots and Moiré fringes. In addition, the performance of the power generation glass with a vacuum structure is superior to other building materials, and the weight does not need to be increased, reducing project costs and installation costs.

[0034] In an alternative embodiment, the photovoltaic glass 10 further includes a second interlayer film 14 and a tempered glass layer 15. The tempered glass layer 15 is disposed on the bottom surface of the vacuum glass layer 13, the second interlayer film 14 is disposed between the vacuum glass layer 13 and the tempered glass layer 15, and the tempered glass layer 15 is connected to the connecting purlin 20.

[0035] Specifically, in this embodiment, by introducing the second interlayer film 14 and the tempered glass layer 15, a composite structure of the vacuum glass layer 13, the second interlayer film 14, and the tempered glass layer 15 is formed. The setting of the tempered glass layer 15 enables the photovoltaic glass 10 to have higher strength and stability when subjected to external pressure or temperature changes, greatly reducing the risk of loss caused by glass breakage. Secondly, the structure of the photovoltaic glass 10 adopts the second interlayer film 14 between the vacuum glass layer 13 and the tempered glass layer 15, which can effectively block heat transfer, reduce heat loss, and improve the heat preservation performance of the photovoltaic glass 10. This improvement enables the photovoltaic glass 10 to maintain good power generation efficiency in cold environments, further expanding its application range. Thirdly, in this embodiment, the tempered glass layer 15 is disposed on the bottom surface of the vacuum glass layer 13 and is connected to the connecting purlin 20, making the structure of the entire photovoltaic glass 10 module more compact and stable. This structural design is beneficial to improving the installation efficiency of the photovoltaic glass 10, reducing the installation cost, and at the same time improving the overall reliability of the photovoltaic power generation system.

[0036] In an alternative embodiment, the connecting purlin 20 includes a support member 21, a fixing base 22, and a connecting member 23; two support members 21 are respectively connected to the left and right sides of the top surface of the fixing base 22, the bottom of the fixing base 22 is fixed on the support back plate 30, and two connecting members 23 are respectively disposed on the two support members 21 and are connected to the photovoltaic glass 10. Specifically, the connecting member 23 can be a rubber strip coated with glue.

[0037] It can be understood that the stability of the connecting purlin 20 often depends on a complex connection structure. In this embodiment, through the three-in-one design of the support member 21, the fixing base 22, and the connecting member 23, the overall structure is made more compact and stable.

[0038] The support member 21 is respectively connected to the left and right sides of the top surface of the fixed seat 22, effectively dispersing the pressure and improving the impact resistance and durability of the connection part.

[0039] Furthermore, the bottom of the fixed seat 22 is fixed on the support back plate 30. This design increases the strength of the overall structure, enabling it to have better anti-deformation ability when bearing external loads, thereby ensuring the firm installation of the photovoltaic glass 10 and avoiding potential safety hazards caused by structural looseness.

[0040] In an alternative embodiment, an installation portion 211 for connecting the connecting member 23 is provided at the top of the support member 21, and the cross-sectional shape of the installation portion 211 is L-shaped.

[0041] It can be understood that the design of the L-shaped cross-sectional shape makes the installation portion 211 of the connecting member 23 have better stability and firmness. The L-shaped cross-section can effectively increase the contact area between the support member 21 and the connecting member 23, thereby enhancing the connection stability. This feature plays a positive role in improving the overall structural strength, making the product more reliable during use and reducing the failures and maintenance costs caused by loose connections.

[0042] Furthermore, the L-shaped cross-sectional installation portion 211 facilitates the installation and disassembly of the connecting member 23. Due to the unique design of the L-shaped cross-section, the connecting member 23 can be more easily aligned and fixed with the support member 21, greatly simplifying the installation process and reducing the installation difficulty. At the same time, the disassembly process is also more convenient, providing convenience for the maintenance and replacement of the connecting member 23.

[0043] In an alternative embodiment, a socket strip 212 is provided in the middle of the support member 21, and a slot 221 for accommodating the socket strip 212 is provided on the fixed seat 22, and the shape of the slot 221 corresponds to the shape of the socket strip 212.

[0044] Specifically, the cross-sectional shape of the socket strip 212 is arrow-shaped, and the shape of the slot 221 is concave-shaped.

[0045] The design of this embodiment makes the connection between the support member 21 and the fixed seat 22 more convenient. The precise matching of the socket strip 212 and the slot 221 greatly reduces the assembly time and improves the production efficiency. Compared with the prior art, there is no need for complex installation steps, and only the socket strip 212 needs to be inserted into the corresponding slot 221, greatly reducing the labor intensity.

[0046] In an alternative embodiment, a bent portion 213 is provided at the bottom of the support member 21, and a card slot 222 is provided on the fixed seat 22, and the bent portion 213 is inserted into the card slot 222.

[0047] It can be understood that by providing a bent portion 213 at the bottom of the support member 21, the support member 21 can be more firmly fixed when inserted into the card slot 222 of the fixed seat 22. This structural design not only improves the overall connection strength, but also avoids structural looseness or detachment caused by unstable connection, improving the safety and reliability of the product.

[0048] In an alternative embodiment, the fixed seat 22 is fixedly connected to the support back plate 30 by bolts.

[0049] In an alternative embodiment, the connecting purlin 20 is made of alloy steel. It can be understood that the main structure of the connecting purlin 20 is made of alloy steel material, which has excellent mechanical properties and corrosion resistance, and can meet the usage requirements in various harsh environments.

[0050] In an alternative embodiment, a waterproof layer 31 is provided on the top surface of the support back plate 30.

[0051] Furthermore, the support back plate 30 is made of a material with a certain strength and toughness, including a top surface, a bottom surface, and four peripheral edges. Its shape and size can be designed according to the actual application scenario; a waterproof layer 31 is provided on the top surface of the support back plate 30. The waterproof layer 31 is made of a material with excellent waterproof performance, such as polymer materials, waterproof coatings, etc. The waterproof layer 31 covers the entire top surface, effectively preventing water penetration.

[0052] A thermal insulation photovoltaic module provided in this embodiment has the following advantages:

[0053] In this embodiment, by adopting the photovoltaic glass 10 with a vacuum structure, the problems of infrared heat insulation and heat conduction heat insulation are effectively solved. Compared with the prior art, this structure enables the power generation glass layer 11 to effectively handle the heat insulation problem even when it is opaque, greatly improving the heat insulation performance of the photovoltaic glass 10; the power generation glass can generate electricity, and the electric energy can be provided to the building through the system; the vacuum glass layer 13 has good heat insulation performance. When the two are combined into one and form a building maintenance structure, it is a product with energy empowerment + energy conservation. By using the method of vacuum medium isolation for heat insulation, compared with the hollow structure, it has less reflectivity during use and will not cause light pollution; secondly, after the vacuum glass layer 13 is combined with the power generation glass, the technical problems of light spots and moiré fringes can be solved; in addition, the power generation glass with a vacuum structure can reduce the heat transfer coefficient to 0.5 W / m2·K without increasing the thickness of the glass or the chamber, and its performance is superior to other building materials. The weight does not need to be increased either, reducing the project cost and installation cost.
