Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to an open frame of a solar photovoltaic component. Background Art
[0002] The photovoltaic module frame is an important component of the photovoltaic solar panel assembly. It is used to fix and seal the frame structure material of the photovoltaic module. The photovoltaic module frame currently used (such as Figure 7 As shown in the figure, when the back load is applied, the torque is greater, the stress of the photovoltaic module frame is concentrated, and it is easy to be damaged). It is composed of a mounting part and a supporting part, wherein the supporting part is a closed cavity. Although this structure can meet the load requirements of the photovoltaic module and provide stable support for the photovoltaic panel, there are significant problems with the closed cavity structure during use, namely, water easily accumulates inside the cavity and the amount of frame material increases, and the cost of photovoltaic module frame parts is high. The closed cavity of the frame is not protected by an anodized film, and crevice corrosion and oxygen concentration difference corrosion are prone to occur in a humid or corrosive environment. Long-term water accumulation will not only affect the strength and stability of the frame, but also cause structural damage to the photovoltaic module, posing a safety hazard and causing serious economic losses. Summary of the invention
[0003] The purpose of the utility model is to provide an open frame of a solar photovoltaic assembly to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an open frame of a solar photovoltaic component, including an A surface, a B surface and a C surface, wherein the A surface includes an upper clamping portion, a mounting portion and a lower clamping portion, and the upper and lower ends of the mounting portion are respectively connected to the upper clamping portion and the lower clamping portion, and a glue overflow groove is provided on the opposite surfaces of the upper clamping portion and the lower clamping portion to store silica gel for encapsulating the solar photovoltaic panel, and a lower bending portion is connected to the outer end of the lower clamping portion, and a plurality of reinforcing ribs are evenly distributed on the inner side of the B surface.
[0005] Preferably, an upper bending portion is connected to the outer end of the C surface.
[0006] Preferably, three reinforcing ribs are evenly distributed on the inner side of the B surface.
[0007] Preferably, the length of the C surface is greater than or equal to the length of the lower clamping portion.
[0008] Preferably, the upper clamping portion is a sloped surface at the upper end surface, sloping downward along the opening direction of the A surface.
[0009] Preferably, the inner side of the intersection of the B surface and the lower clamping portion, and the inner side of the intersection of the B surface and the C surface are both provided with chamfers to serve as guides during frame assembly to facilitate solar panel assembly.
[0010] Preferably, an R angle is provided on the outer side of the intersection of the lower clamping portion and the lower bending portion.
[0011] Technical effects and advantages of the utility model:
[0012] 1. The open-type frame long side section design is adopted to reduce the hidden danger of water corrosion in the frame cavity when the solar photovoltaic modules are used outdoors. This section can greatly save the weight of the frame aluminum extrusion profile, thereby reducing the cost of frame parts.
[0013] 2. By evenly distributing multiple reinforcing ribs (such as three) on the inner side of the B surface, the rigidity and structural strength of the frame are greatly enhanced, which helps to resist external pressure and deformation, ensure the long-term stability and safety of the photovoltaic module, avoid interference with the R angle of the saw cut surface of the corner code, and reinforce the material of the long side.
[0014] 3. The upper clamping part is designed as a slope, which is tilted downward along the opening direction of the A surface. This design can effectively prevent the accumulation of rainwater and dust from affecting the power generation of the solar photovoltaic module, and is also convenient for the installation and positioning of the internal and external pressure blocks of the photovoltaic module, making the installation of the pressure blocks more firm and reliable, and further simplifying the installation process.
[0015] 4. When used as a long frame, the length of the C surface is greater than the length of the lower clamping part. Combined with the upper bending design, it ensures that the long frame can meet the requirements of M8 bolt installation when encapsulating photovoltaic modules, and can also reinforce the long side materials when the front / back load of the photovoltaic module is applied.
[0016] 5. The coordinated use of the upper bend and the lower bend can not only reinforce the strength of the stress-bearing surface, but also form an installation coordination with the angle bracket at the angle bracket installation location. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1 , Figure 3-Figure 6 A specific embodiment of an open frame of a solar photovoltaic module of the utility model is shown: it includes an A surface, a B surface and a C surface, the A surface includes an upper clamping part 1, a mounting part 2 and a lower clamping part 3, the upper and lower ends of the mounting part 2 are respectively connected to the upper clamping part 1 and the lower clamping part 3, a glue overflow groove 11 is opened on the opposite surface of the upper clamping part 1 and the lower clamping part 3, a lower bending part 31 is connected to the outer end of the lower clamping part 3, and a plurality of reinforcing ribs 4 are evenly distributed on the inner side of the B surface;
[0026] An upper bending portion 5 is connected to the outer end of the C surface;
[0027] Three reinforcing ribs 4 are evenly distributed on the inner side of the B surface;
[0028] The length of the C surface is greater than the length of the lower clamping portion 3 (when used as a long frame), or equal to the length of the lower clamping portion 3 (when used as a short frame);
[0029] The upper clamping portion 1 is a sloped surface at the upper end surface, which is inclined downward along the opening direction of the A surface;
[0030] The inner side of the intersection between the B surface and the lower clamping portion 3 and the inner side of the intersection between the B surface and the C surface are both provided with R corners.
[0031] In addition, to facilitate the assembly of the solar panel, a chamfer is provided on the outer side of the intersection of the lower clamping portion 3 and the lower bending portion 31 to serve as a guide during frame assembly.
[0032] like Figure 3 and Figure 4 As shown, this open frame is combined with the traditional aluminum extrusion inner and outer pressure blocks in the market, which can realize the rapid installation of photovoltaic modules in a stable and reliable manner;
[0033] like Figure 5As shown, the C surface of the long frame can be quickly installed with M8 bolts, and it is firm and reliable. When the back of the photovoltaic module is loaded, the torque is smaller and the force is more reasonable.
[0034] like Figure 6 As shown, the schematic diagram of the back load force of the open-frame photovoltaic module shows that the moment is smaller when back-loaded, and the load force is more uniform and reasonable.
[0035] First, align the edge of the solar photovoltaic module with the A surface of the open frame to ensure that the edge of the module is tightly clamped by the upper clamping part 1 and the lower clamping part 3. The upper clamping part 1 and the lower clamping part 3 fix the edge of the photovoltaic module by clamping. Since the upper clamping part 1 is a sloped surface at the upper end face, it is inclined downward along the opening direction of the A surface, which helps the edge of the module to slide in and be fixed smoothly; a plurality of (specifically three here) reinforcing ribs 4 are evenly distributed on the inner side of the B surface. These reinforcing ribs can increase the overall strength of the frame, prevent the frame from being deformed or damaged during installation and use, avoid interference with the R angle of the sawing surface of the corner code, and reinforce the material of the short side. The lower bending part 3 1 and the upper bending portion 5 are the outer end connecting parts of the lower clamping portion 3 and the C-face respectively. Through the bending design, they can further increase the contact area between the frame and the installation surface or other components, improve the stability and firmness of the connection, reinforce the strength of the force-bearing surface, and form an installation match with the corner bracket at the corner bracket installation position; the length of the C-face can be designed to be greater than or equal to the length of the lower clamping portion 3 as needed; when the length of the C-face is greater than the lower clamping portion 3, the frame can be used as a long frame; when the lengths of the two are equal, the frame can be used as a short frame. This design enables the same frame to adapt to photovoltaic modules of different sizes, thereby improving the versatility and flexibility of the product.
