Description

Technical Field

[0001] The utility model relates to the technical field of wind pressure and impact resistance of photovoltaic components, in particular to a device for resisting wind pressure and impact of photovoltaic components. Background Art

[0002] With the continuous development of renewable energy technology, photovoltaic modules, as the core part of solar power generation systems, are increasingly widely used. However, photovoltaic modules are often faced with various complex climate conditions and natural disasters such as wind pressure and hail impact when operating in outdoor environments for a long time. These environmental factors may cause damage to photovoltaic modules, reduce their power generation efficiency and safety, and even cause safety accidents.

[0003] Although the traditional photovoltaic module structure design can meet the basic power generation needs, it has certain limitations in terms of wind pressure and impact resistance. For example, under strong winds, the packaging layer, transparent cover layer and back panel of the photovoltaic module may be deformed or cracked due to pressure; under the impact of hail and other impact objects, the surface of the photovoltaic module may be damaged, affecting the power generation efficiency and service life.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for resisting wind pressure and impact of photovoltaic components comprises a cell, an encapsulation layer, a transparent covering layer, a back plate and a reinforcement structure, wherein: an encapsulation layer is arranged above the cell, and the encapsulation layer is covered with a transparent covering layer, a back plate is arranged below the cell, a support structure is arranged on the periphery of the side of the transparent covering layer, and a corrugated structure is arranged at the contact position between the cell and the side of the encapsulation layer and the support structure, a reinforcement structure is installed at the bottom of the back plate, the reinforcement structure comprises an outer frame surrounding the outside and a honeycomb unit uniformly expanded and filled inside, and hexagonal support members are arranged around the honeycomb unit, the honeycomb unit comprises a hexagonal support member and a sealing plate fixed on the back of the support member, and the support member is two sets of triangular support plates connected to each other.

[0007] Furthermore, the corrugated structure includes protective surface layers on both sides, corrugated oblique supports between the two groups of protective surface layers, and a filling cavity formed by the side surfaces of the oblique supports, and the filling cavity is filled with rubber particles.

[0008] Furthermore, the encapsulation layer is encapsulated by EVA, and the transparent covering layer arranged outside the encapsulation layer is made of reinforced glass material, while the back panel is made of polymer composite material, and the outer supporting structure is made of aluminum alloy material.

[0009] Furthermore, the sealing plate and triangular support plate arranged on the honeycomb unit are made of PP plastic injection molding, and the cross-section of the two sets of triangular support plates on the support member is a triangular structure.

[0010] Furthermore, the outer frame provided on the reinforcing structure is formed of a hollow square tube, and the outer frame fits the supporting structure. Beneficial Effects

[0011] By designing a unique reinforcement structure and corrugated structure, this device can significantly improve the wind pressure and impact resistance of photovoltaic modules. The honeycomb unit and hexagonal support design of the reinforcement structure, as well as the oblique support and rubber particle filling in the corrugated structure, provide additional support and protection for photovoltaic modules, allowing them to remain stable in the face of strong winds and impacts.

[0012] During the manufacturing process, a series of structural innovations and reinforcement measures were also proposed, such as adding metal reinforcement ribs around the outer frame, strengthening the supporting structure, enhancing the corrugated structure, and adding small pillars or reinforcement ribs inside the honeycomb units. These measures can further improve the wind pressure and impact resistance of photovoltaic modules and ensure their stability and safety in practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Specific implementation method 1: The utility model provides a technical solution:

[0019] A device for resisting wind pressure and impact of photovoltaic components comprises a cell 1, an encapsulation layer 2, a transparent covering layer 3, a back plate 4 and a reinforcement structure 5, wherein: the encapsulation layer 2 is arranged above the cell 1, and the encapsulation layer 2 is covered with the transparent covering layer 3, the back plate 4 is arranged below the cell 1, a support structure 7 is arranged on the outer periphery of the side of the transparent covering layer 3, and a corrugated structure 6 is arranged at the contact position between the side of the cell 1 and the encapsulation layer 2 and the support structure 7, and a reinforcement structure 5 is installed at the bottom of the back plate 4, the reinforcement structure 5 comprises an outer frame 51 surrounding the outside and a honeycomb unit 52 uniformly expanded and filled inside, and hexagonal support members 53 are arranged around the honeycomb unit 52, the honeycomb unit 52 comprises a hexagonal support member 53 and a sealing plate 521 fixed on the back of the support member 53, and the support member 53 is two sets of triangular support plates 522 connected to each other.

[0020] The corrugated structure 6 includes protective surface layers 62 on both sides, corrugated oblique supports 63 between the two groups of protective surface layers 62 , and a filling cavity 61 formed by the side surfaces of the oblique supports 63 , and the filling cavity 61 is filled with rubber particles.

[0021] The encapsulation layer 2 is encapsulated by EVA, and the transparent covering layer 3 arranged outside the encapsulation layer 2 is made of reinforced glass material, while the back plate 4 is made of polymer composite material, and the outer supporting structure 7 is made of aluminum alloy material.

[0022] The sealing plate 521 and the triangular support plate 522 provided on the honeycomb unit 52 are made of PP plastic injection molding, and the cross-section of the two sets of triangular support plates 522 on the support member 53 is a triangular structure.

[0023] The outer frame 51 provided on the reinforcing structure 5 is formed by a hollow square tube, and the outer frame 51 fits the supporting structure 7 .

[0024] The cell 1 is the core part of the photovoltaic module, responsible for converting light energy into electrical energy. The cell converts solar radiation energy into direct current electricity through the photoelectric effect on its surface, providing power for the entire system.

[0025] The main function of using EVA material in the encapsulation layer 2 is to protect the battery cell from erosion by the external environment, such as moisture, dust and ultraviolet rays, etc. At the same time, it can also enhance the bonding force between the battery cell and the transparent cover layer to ensure the overall stability of the component.

[0026] The transparent cover layer 3 is made of tempered glass, which not only protects the encapsulation layer and the cells, but also allows sunlight to pass through smoothly and shine on the cells. The tempered glass material has excellent impact resistance and wear resistance, and can effectively resist damage from natural factors such as hail and sandstorms.

[0027] The back sheet 4 is made of polymer composite material and is located on the back of the battery cell to provide support and protection. It not only prevents external moisture and humidity from invading, but also improves the insulation performance of the components to ensure the safe operation of the system.

[0028] The outer frame 51 of the reinforcement structure 5: The outer frame adopts a hollow square tube structure and is close to the support structure 7, providing additional support and protection for the entire photovoltaic module to prevent external forces from damaging the module.

[0029] The honeycomb unit 52 is composed of a hexagonal support member 53 (formed by two sets of triangular support plates 522 connected together) and a sealing plate 521. This structure has excellent compression and impact resistance. When external forces act on the components, the honeycomb unit can effectively disperse and reduce the impact force and protect the battery cells from damage.

[0030] The protective surface layer 62 of the corrugated structure 6 is located on the side of the battery cell and plays a role in preventing external objects from directly contacting the battery cell.

[0031] The oblique supports 63 are arranged in a corrugated manner, and together with the protective surface layers on both sides, form a filling cavity 61. This structure can absorb and disperse the impact force through the deformation of the oblique supports when subjected to external impact, while the rubber particles in the filling cavity can also play a buffering role, further improving the impact resistance.

[0032] The support structure 7 is made of aluminum alloy and is located outside the transparent cover layer. It not only plays a role of fixing and supporting, but also enhances the overall rigidity and stability of the component. It fits tightly with the outer frame 51 to form a stable frame to protect the internal battery cells and other components.
