Reinforced glass fiber photovoltaic frame profile structure

Abstract

The utility model discloses a reinforced glass fiber photovoltaic frame profile structure, which comprises a frame profile formed by curing a glass fiber bundle through resin, and glass fibers of the glass fiber bundle extend along the length direction of the frame profile. Reinforcing framework layers integrally formed with the main bearing wall and the connecting piece mounting wall are arranged in the main bearing wall and the connecting piece mounting wall correspondingly, and each reinforcing framework layer is formed by stacking at least one layer of framework fabric woven in a grid shape. Due to the fact that the framework fabric layers of the reinforcing framework layers are woven in the latticed mode, when the framework fabric layers and the glass fiber bundles are solidified into a whole through resin, the strength, toughness and other mechanical properties of the corresponding positions can be effectively improved, and particularly, the connecting piece installation wall is provided with the reinforcing framework layers additionally arranged. By means of the technical scheme, the hole opening position can have high strength and toughness tending to be consistent in the circumferential direction, even if the profile is in outdoor severe conditions for a long time, microcracks cannot occur on the profile, and therefore a connecting piece can be reliably fixed in a riveting or bolt connecting mode.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frame material technology, specifically to a reinforced glass fiber photovoltaic frame profile structure. Background Technology

[0002] A solar photovoltaic (PV) frame is a profile frame and bracket used to fix solar panel modules. It serves to secure and seal the solar panels, as well as enhance their strength. Simultaneously, solar PV frames must be easy to use, transport, and install in various environments over a long period, and their performance should not be affected even if scratches appear on the surface.

[0003] Existing composite photovoltaic frames typically use a pre-embedded nesting method to connect the short sides to the long sides, with adhesive used to bond the composite profile and the nest. The amount of adhesive used affects the ease and efficiency of photovoltaic frame installation. Furthermore, the adhesive has poor flowability between the photovoltaic frame and the nest, easily leading to weak adhesion. Adhesive overflow is also prone to occur, causing issues such as misaligned corner gaps during short-side bracket installation, impacting module yield and assembly efficiency.

[0004] To address this, the applicant in this case designed a photovoltaic frame structure as disclosed in Chinese Utility Model Patent Publication No. CN221103272U. The first fixing member (pressure block) is an irregularly shaped structure adapted to the photovoltaic frame, which not only increases the force-bearing area and improves the connection strength of the pressure block, but also effectively prevents the risk of slippage due to the twisting and deformation of the photovoltaic frame under external force, thus improving the reliability of the connection between the first fixing member and the photovoltaic frame and increasing the stability of the structure. Meanwhile, the connecting parts of this photovoltaic frame structure (e.g., corner brackets) are limited to structural adhesive fixation, increasing operational inconvenience.

[0005] To accommodate widespread market application and ensure ease of operation, a connection method is required where connectors (e.g., angle brackets) are drilled and installed on surface D (see connector mounting wall 16 of this application) (followed by riveting or bolting). Please refer to... Figure 1 Existing photovoltaic frame profiles are all made of glass fibers extending along the length direction and cured with resin. Since outdoor environments are usually harsh, if the force is borne solely by the glass fiber bundles extending along the length of the profile, when installing through holes drilled on the D side, the structural strength of the holes is only particularly high in the direction parallel to the extension of the glass fibers (the stress point is only along the extension direction of the glass fiber bundle), while it is particularly poor in the direction perpendicular to the extension of the glass fibers. Therefore, after long-term use, the photovoltaic frame is prone to developing micro-cracks extending along the length of the profile, which in turn leads to loosening during riveting or bolting connections, making it impossible to reliably fix the connectors.

[0006] Solving these problems is now a top priority. Utility Model Content

[0007] In view of this, the present invention provides a reinforced glass fiber photovoltaic frame profile structure.

[0008] The technical solution is as follows:

[0009] The first aspect of this application relates to a reinforced glass fiber photovoltaic frame profile structure, comprising a frame profile formed by curing glass fiber bundles with resin. The glass fibers of the glass fiber bundles extend along the length of the frame profile. The frame profile includes a rectangular tube portion with a rectangular tubular structure. One sidewall of the rectangular tube portion is a main support wall. The outer edge of one side of the main support wall protrudes from the rectangular tube portion in the width direction and is bent to form a silicon plate support cantilever perpendicular to the main support wall. The silicon plate support cantilever, the main support wall, and the frame profile together form a silicon plate mounting groove. The sidewall of the rectangular tube portion away from the silicon plate support cantilever is a connector support wall. The outer edge of the connector support wall away from the main support wall protrudes from the frame profile. The sidewall of the rectangular tube portion away from the main support wall is a connector mounting wall. Both the main support wall and the connector mounting wall are provided with an integrally formed reinforcing skeleton layer. The reinforcing skeleton layer is composed of at least one layer of skeleton fabric woven in a mesh pattern.

[0010] The above-mentioned reinforced glass fiber photovoltaic frame structure, with its mesh-woven skeleton fabric layer, effectively improves the strength and toughness of corresponding locations when it is cured with resin, thus enhancing the mechanical properties. The addition of a reinforced skeleton layer to the connector mounting wall ensures consistent high strength and toughness in the circumferential direction at the opening locations. Even under harsh outdoor conditions, the profile will not develop micro-cracks, allowing for highly reliable fixing of connectors (e.g., angle brackets) via riveting or bolting. This also strengthens the structural strength of the connector mounting wall itself, further improving the reliability of connector installation. Furthermore, the addition of a reinforced skeleton layer to the main support wall significantly increases the structural strength of the main load-bearing surface of the photovoltaic frame profile and improves overall straightness, making it less prone to bending deformation during long-term storage (uncut).

[0011] In some embodiments, the connecting support wall is also provided with the reinforcing skeleton layer integrally formed therewith.

[0012] In some embodiments, the side wall of the rectangular tube portion adjacent to the silicon substrate mounting groove is also provided with the reinforcing skeleton layer integrally formed therewith.

[0013] In some embodiments, the skeleton fabric layer is woven from bundles of glass fibers in a mesh pattern.

[0014] In some embodiments, the outer surfaces of the main support wall, the silicon plate support cantilever, and the connector mounting wall are integrally covered with a weather-resistant reinforcing layer.

[0015] In some embodiments, the weather-resistant reinforcing layer is formed by stacking at least one layer of weather-resistant fabric woven in a mesh pattern, wherein the weather-resistant fabric layer is formed by woven bundles of glass fibers in a mesh pattern.

[0016] In some embodiments, the outer surface of the frame profile is integrally covered with a weather-resistant reinforcing layer.

[0017] In some embodiments, the weather-resistant reinforcing layer is formed by stacking at least one layer of weather-resistant fabric woven in a mesh pattern, wherein the weather-resistant fabric layer is formed by woven bundles of glass fibers in a mesh pattern. Attached Figure Description

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] Example 1:

[0031] like Figure 2 and Figure 11 As shown, a reinforced glass fiber photovoltaic frame profile structure mainly includes frame profile 1, which is largely the same as the photovoltaic frame structure disclosed in Chinese Utility Model Patent Publication No. CN221103272U.

[0032] Specifically, the frame profile 1 of this embodiment includes a rectangular tube portion 11, which has a rectangular tubular structure, meaning that the cross-section of the rectangular tube portion 11 is approximately a rectangular ring structure. One side wall of the rectangular tube portion 11 is a main support wall 12, which is typically a large surface of the rectangular tube portion 11 and has better load-bearing capacity. Furthermore, one outer edge of the main support wall 12 protrudes from the rectangular tube portion 11 in the width direction and is bent to form a silicon plate support cantilever 13 perpendicular to the main support wall 12. The silicon plate support cantilever 13, the main support wall 12, and the frame profile 1 together form a silicon plate mounting groove 14. The silicon plate mounting groove 14 is a U-shaped groove, and the silicon plate is installed in the silicon plate mounting groove 14. The side wall of the rectangular tube section 11 away from the silicon plate support cantilever 13 is a connector support wall 15. The outer edge of the connector support wall 15 away from the main support wall 12 protrudes from the frame profile 1. The side wall of the rectangular tube section 11 away from the main support wall 12 is a connector mounting wall 16.

[0033] In this embodiment, both the main support wall 12 and the connector mounting wall 16 are provided with a reinforcing skeleton layer 2, which is composed of at least one layer of skeleton fabric woven in a mesh pattern. Meanwhile, the frame profile 1 is formed by curing glass fiber bundles with resin, with the glass fibers of the glass fiber bundles extending along the length of the frame profile 1. Therefore, each reinforcing skeleton layer 2 is integrally formed with the glass fiber bundles of the frame profile 1 through resin curing. Thus, because the skeleton fabric layer of the reinforcing skeleton layer 2 is woven in a mesh pattern, when it is integrally cured with the glass fiber bundles through resin, the mechanical properties such as strength and toughness at the corresponding locations can be effectively improved.

[0034] The connector mounting wall 16, by adding a reinforcing skeleton layer 2, not only ensures that the opening positions have consistent high strength and toughness in the circumferential direction, thus enabling the connector (e.g., corner bracket) to be reliably fixed by riveting or bolting, but also enhances the structural strength of the connector mounting wall 16 itself, thereby further improving the reliability of connector installation.

[0035] By adding a reinforcing skeleton layer, the main support wall 12 not only greatly increases the structural strength of the main load-bearing surface of the photovoltaic frame profile, but also improves the overall straightness and is not prone to bending deformation during long-term storage (when not cut and processed).

[0036] Furthermore, the width of the reinforcing skeleton layer 2 in both the main support wall 12 and the connector mounting wall 16 is as wide as possible; that is, the outer edges of the reinforcing skeleton layer 2 in the main support wall 12 are as close as possible to the outer edges of the main support wall 12, and the outer edges of the reinforcing skeleton layer 2 in the connector mounting wall 16 are as close as possible to the outer edges of the connector mounting wall 16. This results in better strength and toughness for both the main support wall 12 and the connector mounting wall 16.

[0037] Furthermore, the skeleton fabric layer is preferably made of bundles of glass fibers woven in a mesh pattern. This not only ensures the reinforcement effect meets the requirements but also provides better bonding with the glass fiber bundles of the frame profile 1, resulting in greater durability. It should be noted that the skeleton fabric layer can also be made of other fibers woven in a mesh pattern, as long as the strength and toughness requirements are met.

[0038] The molding of the reinforced glass fiber photovoltaic frame profile in this embodiment is carried out according to the following steps:

[0039] Step 1: Clamp each reinforcing skeleton layer 2 between the glass fiber bundles of the frame profile 1 according to the set position. After completion, impregnate the entire structure with resin.

[0040] Step 2: Under the action of the traction machine, the material is pulled into the mold and cured at a specific temperature.

[0041] Step 3: Cut according to the design and drill holes at the designated positions on the connector mounting wall 16.

[0042] Step 4: Perform surface treatment on the profile, usually by grinding and flame burning.

[0043] Step 5: Apply coating to the designated locations on the profile surface.

[0044] The resin is not limited to different resin matrices such as unsaturated, polyurethane, epoxy, and vinyl, and different additives and color pastes are used; the resins are changed according to different processes.

[0045] Pultrusion temperature zone curing, temperature range 50~260℃.

[0046] Example 2:

[0047] Based on the current market situation, besides the method of installation using the clamping block connection assembly, there is also an installation method that involves drilling holes in the connector support wall 15 and then fixing it to the purlin with bolts. Therefore, please refer to [link / reference needed]. Figure 3 The structure of the frame profile 1 in this embodiment of the reinforced glass fiber photovoltaic frame profile is largely the same as that of the frame profile 1 in Embodiment 1. The difference lies in that the length of the connector support wall 15 is longer than that of the connector support wall 15 in Embodiment 1. To ensure reliable support of the connector by the connector support wall 15, a reinforcing skeleton layer 2 integrally formed therewith is also provided in the connector support wall 15 of this embodiment. The material and structure of the reinforcing skeleton layer 2 in the connector support wall 15 are the same as those of the reinforcing skeleton layers 2 in Embodiment 1. At the same time, the outer edges of the two sides of the reinforcing skeleton layer 2 in the connector support wall 15 are as close as possible to the outer edges of the two sides of the connector support wall 15, thereby improving the strength and toughness of the connector support wall 15. Therefore, the opening positions of the connector support wall 15 can have consistent high strength and toughness in the circumferential direction. Even under harsh outdoor conditions for a long time, the profile will not develop micro-cracks, thus enabling reliable fixing to the purlin by bolt connection.

[0048] Example 3:

[0049] Please see Figure 4 The structure of the frame profile 1 in this embodiment is largely the same as that of the frame profile 1 in Embodiment 2. The difference lies in that a reinforcing skeleton layer 2 integrally formed therein is also provided on the side wall adjacent to the silicon substrate mounting groove 14 of the rectangular tube section 11. This improves the overall strength and toughness of the rectangular tube section 11, thereby enhancing the overall strength and toughness of the reinforced glass fiber photovoltaic frame profile structure. The material and structure of the reinforcing skeleton layer 2 in the side wall adjacent to the silicon substrate mounting groove 14 of the rectangular tube section 11 are the same as those of the reinforcing skeleton layers 2 in Embodiment 2. Furthermore, the reinforcing skeleton layers 2 at the location of the rectangular tube section 11 together form a rectangular tubular structure, further improving the overall strength and toughness of the reinforced glass fiber photovoltaic frame profile structure.

[0050] Example 4:

[0051] Please see Figure 5 The reinforced glass fiber photovoltaic frame profile structure in this embodiment is basically the same as that in embodiment 1. The difference is that the outer surfaces of the main support wall 12, the silicon plate support cantilever 13 and the connector mounting wall 16 are integrally covered with a weather-resistant reinforcing layer 3. The weather-resistant reinforcing layer 3 and the glass fiber bundle of the frame profile 1 are integrally formed by resin curing.

[0052] In this embodiment, the weather-resistant reinforcing layer 3 is composed of at least one layer of weather-resistant fabric woven in a mesh pattern. Preferably, the weather-resistant fabric layer is woven from bundles of glass fibers in a mesh pattern, which not only meets the weather resistance requirements but also provides better bonding with the glass fiber bundles of the frame profile 1, resulting in greater durability. It should be noted that the weather-resistant fabric layer can also be made of other fibers woven in a mesh pattern, or it can use common surface weather-resistant structures such as weather-resistant films, as long as the weather resistance requirements are met.

[0053] Therefore, the main surfaces of the reinforced fiberglass photovoltaic frame profile structure are all covered with a resin-rich layer, which can more effectively resist ultraviolet rays. Furthermore, in addition to the strong weather resistance of the resin matrix, the weather-resistant reinforcing layer 3 can be used for extended periods in harsh outdoor environments, maintaining stable performance even after prolonged exposure to ultraviolet rays, humidity, heat, and cold. It also exhibits good high and low temperature resistance, allowing for use over a wide temperature range, suitable for both low and high temperature environments, and providing corrosion resistance in humid environments. Moreover, the weather-resistant reinforcing layer 3 gives the resin matrix exceptional durability, preventing color fading. Therefore, the reinforced fiberglass photovoltaic frame profile structure of this embodiment does not require surface spraying or pretreatment during use, significantly improving ease of use.

[0054] The molding of the reinforced glass fiber photovoltaic frame profile in this embodiment is carried out according to the following steps:

[0055] Step 1: Clamp each reinforcing skeleton layer 2 between the glass fiber bundles of the frame profile 1 according to the set position, and wrap the weather-resistant reinforcing layer 3 over the glass fiber bundles of the frame profile 1 according to the set position. After completion, impregnate the whole with resin.

[0056] Step 2: Under the action of the traction machine, the material is pulled into the mold and cured at a specific temperature.

[0057] Step 3: Cut according to the design and drill holes at the designated positions on the connector mounting wall 16.

[0058] The resin is not limited to different resin matrices such as unsaturated, polyurethane, epoxy, and vinyl, and different additives and color pastes are used; the resins are changed according to different processes.
