Abstract
Description
Technical Field
[0001] This utility model relates to the field of lightweight photovoltaic module edge protection strip technology, specifically a photovoltaic module edge protection strip. Background Technology
[0002] As photovoltaic modules are used in more and more diverse applications, there is a growing trend of installing photovoltaic modules on rooftops with insufficient load capacity, especially in light steel factories, farm sheds, and villas.
[0003] Currently, lightweight glass-based components, designed to replace flexible components and for cost-effective and convenient installation, are generally frameless or have a small, thin frame, which is then glued to the metal roof. However, both frameless and thin-framed components present two major challenges: First, frameless components suffer from high breakage rates during transport due to the glass edges being weak points, exceeding 1% according to surveys. Therefore, lightweight glass-based components require edge protection materials. Second, thin frames have small cross-sections and narrow glue channels, making them prone to deformation. Existing glue application and frame assembly equipment cannot be automated, and even modifications are difficult to achieve compatibility. These two issues hinder the development of lightweight glass-based components, especially ultra-thin glass-based components.
[0004] Existing technologies include directly using frameless components, i.e., the glass edges are frameless for edge protection; and secondly, using methods such as "U-shaped" (e.g.) Figure 5 (As shown) Thin frames such as the "Y-shaped" frame are generally made of aluminum, polyurethane, or other polymers. They require silicone filling in the glue groove and then being manually snapped onto the module edge for edge protection. This results in a high rate of breakage during transportation and handling when using frameless modules, as the glass edges are stress weak points; surveys and internal verification indicate a breakage rate exceeding 1%. If thin frames such as "U-shaped" or "Y-shaped" frames are used, their small cross-section and narrow glue grooves make them prone to deformation. Existing glue application and frame assembly equipment cannot be automated, and even modifications are difficult to achieve compatibility. Therefore, these two problems restrict the development and application of glass-based, especially ultra-thin glass-based lightweight modules. Utility Model Content
[0005] The purpose of this invention is to provide a protective strip for photovoltaic modules to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module edge protector strip, including a protective edge strip, a laminate insertion port is provided on one side of the protective edge strip, two inner support strips are fixedly connected to both sides of the inner wall of the laminate insertion port, a buffer strip is provided inside the laminate insertion port, and an internal steel strip is provided inside the protective edge strip.
[0007] As a further preferred embodiment of this technical solution, the protective edge strip is composed of a wear-resistant protective layer and an outer rubber buffer layer. The outer rubber buffer layer is disposed on the outside of the built-in steel strip, and the wear-resistant protective layer is disposed on the outside of the outer rubber buffer layer.
[0008] As a further preferred embodiment of this technical solution, the buffer strip is composed of a support layer, an isolation layer and an inner buffer cotton layer. The support layer is made of polyurethane, the isolation layer is made of polyethylene, and the inner buffer cotton layer is made of polyester fiber foam material.
[0009] As a further preferred embodiment of this technical solution, the inner support strip is composed of an inner rubber buffer layer and a tough metal plate. The inner rubber buffer layer is wrapped around the outside of the tough metal plate, and one end of the tough metal plate is fixedly connected to the built-in steel strip.
[0010] As a further preferred embodiment of this technical solution, a photovoltaic laminate is provided inside the lamination insertion port, and the outer side of the photovoltaic laminate is in contact with four inner support strips and buffer strips.
[0011] As a further preferred embodiment of this technical solution, the protective edge strip can be segmented and wrapped around the outside of the photovoltaic laminate.
[0012] This utility model provides a protective strip for photovoltaic modules, which has the following beneficial effects:
[0013] (1) This utility model solves the problem that existing ultra-thin glass-based lightweight components cannot be automatically glued and framed on existing equipment by using special edge protection strips and simple edge sealing methods. The photovoltaic module edge protection strip described in this application can wrap ultra-thin glass-based components with its special press-type frame assembly, which can effectively protect the glass edge of the component from bumps and breakages and can quickly achieve simple frame assembly without spending a lot of money to develop new equipment, and is not limited to the problem that existing equipment cannot automatically assemble U-shaped frames.
[0014] (2) The present invention uses a tough metal plate to quickly restore the inner support strip when the photovoltaic laminate is removed from the insertion port of the laminate. At the same time, it provides good support from both sides of the photovoltaic laminate during the insertion process, which makes it easier to wrap the protective strip around the outside of the photovoltaic laminate and facilitates the use of the protective strip.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a photovoltaic module edge protector includes a protective edge strip 1. A laminate insertion port 2 is provided on one side of the protective edge strip 1. Two inner support strips 3 are fixedly connected to both sides of the inner wall of the laminate insertion port 2. A buffer strip 5 is provided inside the laminate insertion port 2. The inner support strip 3 is composed of an inner rubber buffer layer 12 and a tough metal plate 13. The inner rubber buffer layer 12 wraps around the outside of the tough metal plate 13. One end of the tough metal plate 13 is fixedly connected to an internal steel strip 4. A photovoltaic laminate 9 is provided inside the laminate insertion port 2. The outside of the photovoltaic laminate 9 is in contact with the four inner support strips 3 and the buffer strip 5. The protective edge strip 1 can be segmented and wrapped around the outside of the photovoltaic laminate 9.
[0023] When using the protective edge strip 1, first select either a segmented or integral protective edge strip 1 according to the specifications of the photovoltaic laminate 9. Then, wrap the protective edge strip 1 around the outside of the photovoltaic laminate 9. Next, press the protective edge strip 1 to deform the built-in steel strip 4 inside, thereby compressing the protective edge strip 1 against the outside of the photovoltaic laminate 9, thus improving the protection effect. Thus, the protective edge strip 1, with its special press-type frame assembly, can wrap ultra-thin glass-based modules, effectively protecting the edges of the module glass from impacts and breakages, and also quickly achieving simple frame assembly. The tough metal plate 13 has good resilience and can provide stable support while compressing the photovoltaic laminate 9.
[0024] like Figures 1-4 As shown, the protective edge strip 1 is composed of a wear-resistant protective layer 10 and an outer rubber buffer layer 11. The outer rubber buffer layer 11 is located on the outside of the inner steel strip 4, and the wear-resistant protective layer 10 is located on the outside of the outer rubber buffer layer 11.
[0025] The wear-resistant protective layer 10 enhances the external protection capability of the protective edge strip 1. When the protective edge strip 1 rubs against the ground, it can effectively protect the inner outer rubber buffer layer 11, thereby facilitating the use of the protective edge strip 1 and extending its service life.
[0026] like Figures 1-4 As shown, the buffer strip 5 consists of a support layer 6, an isolation layer 7, and an inner buffer cotton layer 8. The support layer 6 is made of polyurethane, the isolation layer 7 is made of polyethylene, and the inner buffer cotton layer 8 is made of polyester fiber foam.
[0027] The support layer 6 forms a stable support by contacting one side of the photovoltaic laminate 9 with the other side. The support layer 6 can keep the protective edge strip 1 and the photovoltaic laminate 9 stably fixed. By using polyurethane material, it is ensured that it is not easily deformed under various environmental conditions. The function of the isolation layer 7 is to ensure direct contact between the side of the photovoltaic laminate 9 and the protective edge strip 1, reducing damage caused by material chemical reactions or temperature changes. The inner buffer cotton layer 8 is mainly used to absorb external impacts and vibrations, protecting the photovoltaic module from mechanical damage.
[0028] This utility model provides a protective edge strip for photovoltaic modules. The specific working principle is as follows: When using the protective edge strip 1, firstly, select a segmented protective edge strip 1 (segmented type is mainly used to cover the required position of the photovoltaic laminate 9) or an integral protective edge strip 1 according to the specifications of the photovoltaic laminate 9. Then, wrap the protective edge strip 1 around the outside of the photovoltaic laminate 9, and then press the protective edge strip 1 to deform the built-in steel strip 4 inside, thereby compressing the protective edge strip 1 to contact the outside of the photovoltaic laminate 9. At this time, the inner support strip 3 forms a contact support with the photovoltaic laminate 9, so that the protective edge strip 1 can be fixed on the outside of the photovoltaic laminate 9. The buffer strip 5 can reduce the impact received by the photovoltaic laminate 9 in the laminate insertion port 2, while the protective edge strip 1 can reduce the impact and friction received by its outside, thereby improving the protection effect.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
