Description

Technical Field

[0001] This utility model relates to the field of high light transmittance fiberglass board technology, and in particular to a high light transmittance fiberglass board for use in the photovoltaic industry. Background Technology

[0002] With the rapid development of the photovoltaic industry, the performance requirements for encapsulation materials in photovoltaic modules are increasing. As an important encapsulation material for photovoltaic modules, high-transmittance fiberglass panels not only need to have excellent light transmittance, but also sufficient mechanical strength, impact resistance, and durability to cope with complex and ever-changing outdoor environmental conditions.

[0003] However, existing high-transmittance fiberglass panels generally suffer from insufficient structural strength and poor bending resistance, making them prone to deformation and cracking during long-term use, which affects the overall performance and lifespan of photovoltaic modules.

[0004] Therefore, those skilled in the art have provided a high-transmittance fiberglass board for use in the photovoltaic industry to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-transmittance fiberglass board for the photovoltaic industry. By setting a wave-shaped reinforcing rib with alternating positive and negative arrangements inside the fiberglass substrate, the impact resistance is improved and deformation and cracking are prevented. At the same time, a through hole is opened in the middle and a reinforcing rod is inserted to optimize the stress distribution, significantly enhance the structural strength and bending resistance, and effectively extend the service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-transmittance fiberglass board for use in the photovoltaic industry includes a fiberglass substrate, a high-transmittance coating on the upper end of the fiberglass substrate, an anti-ultraviolet layer on the upper end of the high-transmittance coating, and a self-cleaning coating on the upper end of the anti-ultraviolet layer. The fiberglass substrate has multiple closely arranged, alternating wavy reinforcing ribs inside. Each wavy reinforcing rib has a through hole spaced apart in the middle. The through holes correspond to each other and a reinforcing rod is inserted through them. By using the above technical solution, an alternating wave-shaped reinforcing rib is set inside the fiberglass substrate to improve impact resistance and prevent deformation and cracking. At the same time, a through hole is opened in the middle and a reinforcing rod is inserted to optimize stress distribution, significantly enhance structural strength and bending resistance, and effectively extend service life.

[0007] Furthermore, the reinforcing rod is a glass fiber reinforced composite material rod; Through the above technical solutions, glass fiber reinforced composite materials have excellent corrosion resistance and weather resistance, and can maintain stable performance in complex outdoor environments for a long time, thus extending the service life of glass fiber boards.

[0008] Furthermore, the space between the inner wall of the through hole and the reinforcing rod is filled with thermally conductive silicone. Through the above technical solution, the thermally conductive silicone effectively fills the gap between the through holes and the reinforcing rod, which not only enhances the structural bonding strength but also optimizes the heat conduction path and improves the heat dissipation performance of the fiberglass board.

[0009] Furthermore, the self-cleaning coating is a superhydrophobic nano-coating; Through the above technical solutions, the superhydrophobic nano-coating endows the fiberglass board surface with excellent self-cleaning properties, which can effectively reduce the adhesion of dust and pollutants, reduce the frequency of rainwater rinsing, and maintain high light transmittance for a long time. This design not only improves the power generation efficiency of photovoltaic modules, but also reduces the cost of manual cleaning.

[0010] Furthermore, the high-transmittance coating is a silicon dioxide nano-coating; Through the above technical solution, the silica nano-coating has excellent optical transmittance and anti-reflection properties, which can significantly improve the light transmittance of the fiberglass board and enhance the light absorption efficiency of the photovoltaic module. At the same time, the coating also has good wear resistance and weather resistance, can maintain high light transmittance for a long time, effectively delay material aging, and extend the service life of the photovoltaic module.

[0011] This utility model has the following beneficial effects: 1. This utility model proposes a high-transmittance fiberglass board for the photovoltaic industry. By setting a wave-shaped reinforcing rib with alternating positive and negative arrangements inside the fiberglass substrate, the board is endowed with excellent impact resistance, effectively preventing deformation and cracking, and maintaining good performance even in harsh environments. At the same time, a through hole is opened in the middle and a reinforcing rod passes through it. The combination of the two optimizes the internal stress distribution, significantly improves the overall structural strength and bending resistance of the fiberglass board, and thus effectively extends its service life.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Reference Figure 1-5 This utility model provides a specific implementation method: A high-transmittance fiberglass board for use in the photovoltaic industry includes a fiberglass substrate 1, a high-transmittance coating 2 on the upper end of the fiberglass substrate 1, an anti-ultraviolet layer 3 on the upper end of the high-transmittance coating 2, and a self-cleaning coating 4 on the upper end of the anti-ultraviolet layer 3. The fiberglass substrate 1 has multiple closely arranged, alternating wavy reinforcing ribs 5, each with a through hole 6 spaced apart in the middle. The through holes 6 correspond to each other and a reinforcing rod 7 passes through them. By setting a wave-shaped reinforcing rib 5 with alternating positive and negative directions inside the fiberglass substrate 1, the impact resistance is improved and deformation and cracking are prevented. At the same time, a through hole 6 is opened in the middle and a reinforcing rod 7 is passed through to optimize the stress distribution, significantly enhance the structural strength and bending resistance, and effectively extend the service life.

[0016] The reinforcing rod 7 is a glass fiber reinforced composite material rod. Glass fiber reinforced composite material has excellent corrosion resistance and weather resistance, and can maintain stable performance in complex outdoor environments for a long time, extending the service life of the glass fiber board. The inner wall of the through hole 6 and the reinforcing rod 7 are filled with thermally conductive silicone. The thermally conductive silicone effectively fills the gap between the through hole 6 and the reinforcing rod 7, which not only enhances the structural bonding strength, but also optimizes the heat conduction path and improves the heat dissipation performance of the glass fiber board. The self-cleaning coating 4 is a superhydrophobic nano-coating. The superhydrophobic nano-coating gives the surface of the glass fiber board excellent self-cleaning properties, which can effectively reduce the adhesion of dust and pollutants, reduce the frequency of rainwater washing, and maintain high light transmittance for a long time. This design not only improves the power generation efficiency of photovoltaic modules, but also reduces manual cleaning costs. The high light transmittance coating 2 is a silica nano-coating. The silica nano-coating has excellent optical transmittance and anti-reflection properties, which can significantly improve the light transmittance of the glass fiber board and enhance the light absorption efficiency of photovoltaic modules. At the same time, this coating also has good wear resistance and weather resistance, can maintain high light transmittance for a long time, effectively delay material aging, and extend the service life of photovoltaic modules.

[0017] Working Principle: During use, this high-transmittance fiberglass board effectively disperses external stress through the alternating wave-shaped reinforcing ribs 5 inside the fiberglass substrate 1, improving the overall bending strength and impact resistance of the board and preventing deformation and cracking. The fiberglass reinforced composite material rods penetrating the through holes 6 further enhance structural stability. Their synergistic effect with the thermally conductive silicone filling the inner wall of the through holes 6 not only optimizes the internal stress distribution but also improves the heat dissipation efficiency of the board, reduces the operating temperature of the photovoltaic module, and improves the photoelectric conversion efficiency. At the same time, the silica nano high-transmittance coating 2 and the superhydrophobic nano self-cleaning coating 4 on the surface of the fiberglass board significantly improve light transmittance and reduce contaminant adhesion, maintaining long-term high-efficiency light transmission performance and ensuring that the photovoltaic module can still operate stably in complex environments, extending its service life.
