Description

Technical Field

[0001] The utility model belongs to the technical field related to photovoltaic modules, and particularly relates to a rigid auxiliary strengthening structure for a flexible and lightweight photovoltaic module. Background Technique

[0002] With the gradual increase of the photovoltaic application market and the increasingly wide application range, the demand for various application modules has also increased accordingly. The market also has a demand for lightweighting. The component glass is cancelled, the aluminum frame is cancelled, and the component weight is reduced by 80%-90%, meeting the market requirements. Flexible and lightweight components generally adopt a structure of a reinforced front film (with fiberglass) + adhesive film + battery + adhesive film + backplane. Flexible components can be bent. Most photovoltaic modules are rectangular, and generally, "day" or "eye" bracket reinforcing ribs are designed along this shape.

[0003] However, the existing reinforcing ribs mostly use steel or aluminum profiles. Such materials are relatively heavy in weight and do not meet the lightweight requirements. Moreover, the right-angle connections of the cross-sections of the "day" or "eye" brackets are generally not connected, and are directly connected together through the backplane with silicone. The overall rigidity of the component is poor and the mechanical strength is low. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rigid auxiliary strengthening structure for a flexible and lightweight photovoltaic module, so as to solve the problems in the above background technique that the existing reinforcing ribs mostly use steel or aluminum profiles, such materials are relatively heavy in weight and do not meet the lightweight requirements, and the right-angle connections of the cross-sections of the "day" or "eye" brackets are generally not connected, and are directly connected together through the backplane with silicone, resulting in poor overall rigidity of the component and low mechanical strength.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rigid auxiliary strengthening structure for a flexible and lightweight photovoltaic module, including multiple long-side reinforcing ribs and multiple short-side reinforcing ribs;

[0006] A top plate is arranged at the top of the long-side reinforcing rib. A component insertion plate is arranged on one side of the top plate.

[0008] Preferably, the clamping plate and the connecting plate are integrally formed, the insert block and the connecting plate are integrally formed, and photovoltaic modules can also be installed on the clamping plate. The photovoltaic modules are fixed to the clamping plate with silicone.

[0009] Preferably, the slots are respectively located at both ends and the middle of the component insert plate, and the insert block can be inserted into the slot, with the length of the insert block being between 8-12mm.

[0010] Preferably, the diameter of the insertion hole is 5mm. After the insertion block is inserted into the slot, the pin can be inserted into the insertion hole. The pin can fix the long side reinforcing rib and the short side reinforcing rib to prevent the long side reinforcing rib and the short side reinforcing rib from separating.

[0011] Preferably, both the long-side reinforcing ribs and the short-side reinforcing ribs are made of polyurethane material, which can ensure the lightweight nature of the long-side reinforcing ribs and the short-side reinforcing ribs.

[0024] 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.

[0025] This utility model provides, for example Figure 1-5 The flexible and lightweight photovoltaic module rigid auxiliary reinforcement structure shown includes multiple long-side reinforcing ribs 1 and multiple short-side reinforcing ribs 2;

[0026] The top of the long side reinforcing rib 1 is provided with a top plate 3, and a component insertion plate 4 is provided on one side of the top plate 3. Multiple slots 7 are provided on the component insertion plate 4, and a component fixing mounting plate 5 is provided at the bottom of the component insertion plate 4. Clamping plates 8 are provided above and below the short side reinforcing rib 2, and a connecting plate 9 is provided between the two clamping plates 8. Insertion blocks 6 are provided at both ends of the connecting plate 9, and insertion holes 10 are provided on the insertion blocks 6. Insert pins 13 can be installed inside the insertion holes 10.

[0027] In this embodiment, the structure composed of the long side reinforcing rib 1 and the short side reinforcing rib 2 is mainly used to assist and strengthen the flexible and lightweight photovoltaic module, ensuring the stability of the photovoltaic module 17. The long side reinforcing rib 1 and the short side reinforcing rib 2 are fixed to the photovoltaic module 17 by silicone 16. When the long side and the short side reinforcing ribs are connected, two short side reinforcing ribs 2 are respectively provided on the two edges of the long side reinforcing rib 1. The number of short side reinforcing ribs 2 is at least 3, of which there is 1 at each end of the long side reinforcing rib 1 and 1 in the middle of the long side reinforcing rib 1. The actual number of short side reinforcing ribs 2 can be defined according to the length and strength of the module.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the top plate 3, the module insertion plate 4, and the module fixing mounting plate 5 are integrally formed. The photovoltaic module 17 can be installed on the top plate 3. The top plate 3 and the photovoltaic module 17 are fixed together by silicone 16. The clamping plate 8 and the connecting plate 9 are integrally formed. The insertion block 6 and the connecting plate 9 are integrally formed. The photovoltaic module 17 can also be installed on the upper clamping plate 8. The photovoltaic module 17 is fixed to the clamping plate 8 by silicone 16.

[0030] Preferably, due to the presence of the long side reinforcing rib 1 and the short side reinforcing rib 2 on the back, the junction box can be installed on the back of the component, which reduces the risk of the junction box material aging due to long-term direct exposure to sunlight when the junction box is installed on the front, and also reduces the risk of outdoor rain and other factors to the junction box.

Multiple slots 12 are provided on the side block 11. Pressure blocks 14 can be installed on the slots 12. Pressure blocks 14 can be engaged with the slots 12. Fasteners 15 are installed on the pressure blocks 14. The fasteners 15 are M8 bolts. A bracket 18 is provided below the long side reinforcing rib 1. The pressure blocks 14 are fixedly installed to the bracket 18 by the fasteners 15.

[0032] Preferably, by setting up the side block 11, the slot 12, the pressure block 14, the fastener 15 and the bracket 18, after the photovoltaic module 17 is bonded to the back of the reinforcing rib, the long side reinforcing rib 1 is selected to fix its structure, and a horizontal "F" structure is designed. At the same time, the pressure block 14 is fixed by snapping with the slot 12 and is fixed by the fastener 15 with M8 bolts, which can achieve the purpose of stabilizing and fixing the module.

[0033] Optionally, the number of slots 7 can be customized based on the mechanical strength and length of the component.
