Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation equipment technology, specifically to a photovoltaic module iron pallet, which is suitable for loading, unloading, storage and transportation of various goods, especially for long-distance transportation, outdoor warehousing and on-site turnover of photovoltaic modules. In international trade, it has significant application advantages due to the stability and standardization characteristics of the metal material. Background Technology

[0002] Pallets, as core equipment in logistics operations, are mainly divided into metal pallets and wooden pallets, and are characterized by their compatibility with forklift operations and ease of cargo transportation. Most existing metal pallets are made of galvanized steel sheets, which are processed into profiles by cold bending forming equipment, and then assembled by welding or bonding to form a load-bearing structure. Among them, the stability of the support legs is a key factor in determining the safety of cargo transportation, and directly affects the pallet's load-bearing capacity and service life.

[0003] In the photovoltaic industry, photovoltaic modules (such as solar panels) are fragile, heavy (a single module typically weighs 20-30 kg), and have high requirements for the transportation environment (avoiding severe vibration, moisture, and rust). This places stringent demands on the structural strength, anti-slip performance, and rust resistance of pallets. Traditional wooden pallets are prone to moisture damage and deformation, and their support strength is insufficient. Conventional metal pallets suffer from excessive weight and high transportation costs due to redundant support leg designs. Therefore, developing a high-strength, low-cost iron pallet suitable for transporting photovoltaic modules has become an urgent need in the industry. Utility Model Content

[0004] The purpose of this utility model is to overcome the problems of insufficient support stability, poor weather resistance, and high transportation costs of existing pallets in the transportation of photovoltaic modules. Through the optimized design of W-shaped support feet, combined with rust-proof and anti-slip properties, a steel pallet adapted to photovoltaic modules is provided to achieve the goals of cost reduction, energy saving and improved transportation safety.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A photovoltaic module iron tray, including a main frame;

[0007] The main frame is composed of a plurality of W-shaped bend fittings and a plurality of U-shaped bend fittings that are staggered and fixed together;

[0008] The top surface of the main frame has a load-bearing section;

[0009] The two sides of the load-bearing part are formed by a plurality of W-shaped and U-shaped bending fittings extending vertically to form side frame parts;

[0010] The main frame is also equipped with L-shaped bend fittings on both sides for reinforcement and protection.

[0011] In a preferred embodiment, the W-shaped bend fitting, U-shaped bend fitting, and L-shaped bend fitting are all made of metal and are manufactured by cold bending forming.

[0012] In a preferred embodiment, the W-shaped bend fitting, the U-shaped bend fitting, and the L-shaped bend fitting are connected by welding.

[0013] In a preferred embodiment, the apex angle of the W-shaped bend fitting is in the range of 100°-130°, and the lengths of its two hypotenuses are equal.

[0014] In a preferred embodiment, the surfaces of the W-shaped bend fitting, U-shaped bend fitting, and L-shaped bend fitting are all treated with rust prevention.

[0015] In a preferred embodiment, the rust prevention treatment includes, but is not limited to, galvanizing, painting, or applying rust-preventive grease.

[0016] In a preferred embodiment, the surface of the bearing portion is provided with anti-slip texture.

[0017] In a preferred embodiment, the anti-slip texture is a grid, strip, or dot pattern, and the depth of the anti-slip texture is 0.5mm-2mm.

[0018] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0019] 1. High load-bearing stability: The triangular structure of the W-shaped support feet, combined with welding fixation, can stably support a single photovoltaic module weighing 20-30kg, and the stacked load capacity can reach 1000-2000kg, meeting the needs of logistics and transportation.

[0020] 2. Protect component safety: Anti-slip texture effectively reduces component slippage, side frame avoids lateral collisions, and the edge-wrapping design of L-shaped bend accessories prevents the component edges from being scratched by the sharp edges of the tray.

[0021] 3. Adaptable to complex environments: Rust-proof treatment allows the pallets to be used in environments ranging from -20℃ to 60℃ and humidity above 80%, making them suitable for outdoor warehousing of photovoltaic modules and long-distance sea transport scenarios.

[0022] 4. Reduce overall costs: The W-shaped structure reduces material consumption, the cold bending forming process reduces energy consumption, and the lightweight design increases the number of pallets per shipment, significantly reducing the logistics costs of photovoltaic modules.

[0023] 5. Recyclability: The all-metal material is recyclable and regenerable, which aligns with the green and environmentally friendly concept of the photovoltaic industry and reduces waste disposal costs. Attached Figure Description

[0034] Example 1

[0035] Appendix Figure 1 and 2 The specific technical solution for a photovoltaic module iron tray is as follows:

[0036] The system includes a main frame 1, which is formed by a plurality of W-shaped bend fittings 2 and a plurality of U-shaped bend fittings 3 fixedly arranged in an alternating manner. The top surface of the main frame 1 has a load-bearing part 4 for placing goods to be transported or stored. The two sides of the load-bearing part 4 are formed by a plurality of W-shaped bend fittings 2 and U-shaped bend fittings 3 extending vertically to form side frame parts 5, which can provide lateral restraint for the goods. The two sides of the main frame 1 are also provided with L-shaped bend fittings 6, which are used to reinforce the structure of the main frame 1 and protect its edges (such as edge wrapping to prevent bumps).

[0037] Furthermore, the W-shaped bend fitting 2, U-shaped bend fitting 3, and L-shaped bend fitting 6 are all made of metal (such as galvanized steel sheet) and are manufactured through cold bending forming. Cold bending forming uses metal sheet, strip, or coil as raw material and multiple cold bending forming machines equipped with forming rollers of specific shapes to gradually bend and deform the blank laterally, thereby obtaining the product with the required uniform cross-section. Each forming machine is equipped with multiple forming rollers, and each forming machine group consists of two or more forming machines to ensure that the fittings are accurate in shape and uniform in size.

[0038] The W-shaped bend fitting 2, U-shaped bend fitting 3 and L-shaped bend fitting 6 are connected by welding. Specifically, a welding machine can be used to achieve fully automatic welding (including pre-welding and return welding) to improve the connection strength and assembly efficiency, and ensure the stability of the overall pallet structure.

[0039] To optimize support performance, the W-shaped bend fitting 2 has a apex angle range of 100°-130°, and its two hypotenuses are of equal length. The symmetrical structure distributes the load and enhances support stability. At the same time, the surfaces of the W-shaped bend fitting 2, U-shaped bend fitting 3, and L-shaped bend fitting 6 are all treated with rust prevention. Rust prevention methods include, but are not limited to, galvanizing, painting, or coating with rust-preventive grease to improve the pallet's corrosion resistance in complex environments such as humid and dusty conditions and extend its service life.

[0040] In addition, the surface of the bearing part 4 is provided with anti-slip texture, which can be grid-like, strip-like or dot-like, and the texture depth is 0.5mm-2mm. By increasing the friction between the goods and the bearing part 4, the goods are prevented from sliding during transportation or loading and unloading, thereby further improving transportation safety.

[0041] Optimized design for photovoltaic module applications:

[0042] 1. Structural strength adaptation: The apex angle of the W-shaped bend fitting is in the range of 100°-130° (preferably 120°), and the two hypotenuses are of equal length, forming a stable triangular support structure. Combined with the lateral reinforcement of the U-shaped bend fitting, it can disperse the concentrated load of the photovoltaic module and avoid damage to the edge of the module due to pressure.

[0043] 2. Materials and processes: W-shaped, U-shaped, and L-shaped bend fittings are all made of metal (preferably galvanized steel sheet, 2-3mm thick), and are manufactured by cold bending to ensure structural accuracy; each fitting is connected by welding, and the tensile strength of the weld is ≥300MPa to meet the load-bearing requirements of photovoltaic module stacking (usually 3-5 layers).

[0044] 3. Enhanced weather resistance: All components are treated with anti-rust treatment (including but not limited to galvanizing, painting or coating with anti-rust grease), with the galvanized layer thickness ≥80μm, which can adapt to the humid and high-temperature environment of outdoor storage of photovoltaic modules and prevent pallet rust from contaminating the modules.

[0045] 4. Anti-slip design: The surface of the bearing part is provided with anti-slip texture (grid, strip or dot pattern, depth 0.5mm-2mm) to increase the friction with the back sheet of the photovoltaic module and prevent the module from sliding and colliding due to bumps during transportation.

[0046] 5. Side frame protection: The side frame is 15-20cm high and can fit the edge of the photovoltaic module to provide lateral restraint and prevent the module from tipping over during forklift operation.

[0047] Example 2

[0048] The present invention will be further described below with reference to specific embodiments:

[0049] The iron pallet in this embodiment is used to transport photovoltaic modules with dimensions of 1660mm×1000mm. The main frame 1 is made of 10 W-shaped bend fittings 2 (120° apex angle, 12cm hypotenuse length) and 6 U-shaped bend fittings 3 welded together, with an overall size of 1700mm×1050mm, which is suitable for the size of the modules. The surface of the bearing part 5 is stamped with a grid-like anti-slip texture 7 with a depth of 1mm and a grid spacing of 5cm×5cm, which increases the friction coefficient with the module back plate to 0.6, effectively preventing slippage.

[0050] The side frame section 6 is 18cm high, fitting the thickness of the photovoltaic module (usually 3-5cm), forming lateral protection; the L-shaped bend fitting 4 uses a 5cm×5cm right-angle edge to wrap the edge of the tray to avoid scratching the module; all fittings are made of 2.5m thick galvanized steel plate, which is cold-bent and then painted twice (epoxy zinc-rich paint), with a salt spray resistance of more than 1000 hours.

[0051] In practical applications, the pallet can hold 6 photovoltaic modules in a single layer, stacked in 3 layers for a total of 18 modules, with a total weight of approximately 500 kg. Tests have shown that no modules slipped or the structure deformed during transport at a speed of 60 km / h, fully meeting the logistics requirements of photovoltaic modules.

[0052] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
