Description

Technical Field

[0001] The utility model relates to the technical field of roll-formed profiles, and specifically, to a roll-formed profile for a photovoltaic module, especially a roll-formed profile and a frame for a photovoltaic module. Background Art

[0002] All along, the profiles used for the main body of traditional photovoltaic frames are basically aluminum extruded profiles, which are customized according to customer requirements. Different products correspond to different forms of aluminum photovoltaic frames, with a wide variety. Aluminum materials are expensive, and the greenhouse gas emissions during the manufacturing process of aluminum ingots are extremely high, with large energy consumption, which will bring a series of problems such as environmental pollution. At the same time, due to the low strength of aluminum, in extremely harsh weather conditions, large areas of photovoltaic modules are prone to breakage, causing huge economic losses.

[0003] Steel materials have always been recyclable materials, with low prices and environmental friendliness. With the development of roll-forming technology, the processing of steel special-shaped structural profiles has become easier, and the strength of steel profiles is at least more than 1 time higher than that of aluminum profiles. Therefore, steel photovoltaic module frames have emerged as the times require.

[0004] The overall photovoltaic module frame uses steel materials, replacing the traditional aluminum frame. It has high structural strength and stiffness, good corrosion resistance and long service life. At the same time, it can achieve rapid assembly, high processing efficiency, high economic value, and greatly reduce greenhouse gas emissions and energy consumption, with the advantages of environmental friendliness and green sustainable recycling.

[0005] The aluminum photovoltaic frame specifically has the following disadvantages: a. The strength of aluminum is low, and in extreme working conditions, the overall photovoltaic frame breaks; b. The process involves processes such as aluminum ingots, extrusion, cutting, hole processing, anodizing, etc., with a long process and low efficiency; c. The overall price is relatively high and the economy is low; d. It is not environmentally friendly, with high energy consumption and high carbon emissions; e. The electrical conductivity is poor, which is not conducive to grounding, and it is easy to cause electrochemical corrosion between dissimilar materials when connected to other steel photovoltaic brackets.

[0006] The existing steel photovoltaic frames are mainly divided into the following two types: open type and closed type. a. Open type: The structure and manufacturing process are simple, with light weight and low technical threshold. However, there are low stiffness and strength in the structure, especially poor torsional resistance. Due to structural reasons, the dimensional accuracy is not high, as shown in Figure 1 ; b. Closed type: The closed structure has high performance, making up for the shortcomings of the open type structure. However, due to the complex structure, the process difficulty is high, the processing consistency is poor, there are problems with the assembly accuracy of the frame, and at the same time, when gluing with the photovoltaic panel, it is easy to have the problem of glue overflow. The sealant overflows and requires post-treatment. In addition, when opening holes or making a 180-degree fold in the structure, due to unreasonable design, there is stress concentration, causing subsequent hidden cracks in the material, as shown in Figure 2 shown.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0084] Example 1:

[0085] As Figures 3 to 7 shown, this embodiment provides a roll-pressed profile for a photovoltaic module, including: a support frame 1, a connecting bottom wall 201, a connecting side wall 202, and a connecting top wall 203; one end of the connecting top wall 203 is connected to one end of the connecting side wall 202, the other end of the connecting side wall 202 is connected to one end of the connecting bottom wall 201, and the connecting bottom wall 201, the connecting side wall 202, and the connecting top wall 203 form a slot structure 2 for installing the photovoltaic solar panel 3; the slot structure 2 is connected to the support frame 1, and the support frame 1 is used to support the slot structure 2; a support protrusion structure is formed on the connecting side wall 202, and when the photovoltaic solar panel 3 is installed into the slot structure 2, a first glue overflow space 4 is formed between the connecting side wall 202 and the side end wall of the photovoltaic solar panel 3 through the support protrusion structure. The connecting bottom wall 201 is horizontally arranged. The first step structure 5 is used to form a glue overflow space with the solar panel.

[0086] A first connection end and a second connection end are formed on the support frame 1; the first connection end is connected to the support protrusion structure, and the second connection end is connected to the connecting bottom wall 201. The support protrusion structure is the first step structure 5.

[0087] The first connection end is a vertical wall structure, which is connected to the first step structure 5. The vertical wall structure is supported by the first step structure 5 to support the slot structure 2.

[0088] At the other end of the receiving top wall 203, a second U-shaped bending structure 13 is provided; when the photovoltaic solar panel 3 is installed into the slot structure 2, a fourth glue overflow space 14 is formed between the receiving top wall 203 and the top end wall of the photovoltaic solar panel 3 through the second U-shaped bending structure 13. The second U-shaped bending structure 13 is a bending feature, forming a gap with the solar panel, facilitating glue overflow, and at the same time increasing strength and stiffness.

[0089] The support frame 1 includes a bottom wall 101, a first side wall 102, and a second side wall 103; one end of the first side wall 102 is connected to the bottom wall 101, and the other end of the first side wall 102 forms a first connection end; one end of the second side wall 103 is connected to the bottom wall 101, and the other end of the second side wall 103 forms a second connection end; the bottom wall 101, the first side wall 102, the second side wall 103, and the receiving bottom wall 201 constitute a cavity structure 18. An installation hole is provided on the bottom wall 101, and the installation hole is used for detachable connection with the photovoltaic bracket.

[0090] Both the first side wall 102 and the second side wall 103 are support walls, forming a support structure. The bottom wall 101 is provided with an opening for connection with the photovoltaic bracket. The cavity structure 18 increases the structural strength, stiffness, and stability, and at the same time accommodates corner connectors.

[0091] The roll-formed profile of this embodiment uses a steel strip (such as high-strength steel, stainless steel, weathering steel, etc.) + a pre-coated anti-corrosion coating (which can be a galvanized layer, a galvanized aluminum-magnesium layer, or a galvanized iron alloy, etc.) as raw materials to ensure that the overall material strength is high enough to prevent the overall fracture of the frame under subsequent extreme working conditions. The steel grade is S550GD+ZM, and its strength is higher than 550 MPa; at the same time, a galvanized aluminum-magnesium coating ZM is used, which can effectively prevent the corrosion problem of steel products and improve durability and reliability.

[0092] Based on the existing technology, a glue overflow structure (formed by a glue overflow step / glue overflow groove / glue overflow flange) is provided in this embodiment, forming a glue overflow space in the U-shaped slot. When adding an adhesive (such as structural glue, sealant, etc.) later, it can not only meet the fixation and sealing between the frame and the solar photovoltaic panel, but also achieve the glue overflow function to prevent the technical problem of external glue overflow.

[0093] In this embodiment, at the U-shaped slot, a folding structure is provided to support or fix the slot and the solar panel, increasing the section modulus of the structure and improving the structural stability and strength.

[0094] This embodiment reduces stress concentration in the structure, especially in the 180-degree bending process, through reasonable mold settings and hole position settings, thereby preventing hidden cracks in the material of the structure during long-term use.

[0095] The present embodiment is used for the rolled profile and frame of the photovoltaic module. The rolled profile of the present embodiment is mainly used for the frame assembly of the photovoltaic module. The rolled profile is made of steel strip (such as high-strength steel, stainless steel, weathering steel, etc.) + pre-coated anti-corrosion coating (which can be a galvanized layer, a galvanized aluminum-magnesium layer, or a galvanized iron alloy, etc.) as raw materials. After being roll-formed in successive passes, it is set to a steel special-shaped rolled profile with a U-shaped slot, an overflow glue structure (overflow glue space), a support cavity, and a double-layer folding assembly structure. Using the rolled profile, after beveling at an angle at both ends, the corners of the four frames are combined with corner connectors, fasteners, etc. to splice into a frame. An adhesive (such as structural adhesive, sealant, etc.) is set in the U-shaped slot of the frame for fixing and sealing between the frame and the solar photovoltaic panel. The frame size can be adjusted in width and length to form photovoltaic modules of different models.

The receiving bottom wall 201 is set at an inclined angle to facilitate the reserved gap with the solar panel and facilitate glue overflow.

[0102] Example 5:

[0103] As Figure 12 and Figure 13 shown, the difference between this embodiment and Embodiment 3 is that a second stepped structure 11 is formed on the receiving bottom wall 201; when the photovoltaic solar panel 3 is installed into the slot structure 2, a third glue overflow space 12 is formed between the receiving bottom wall 201 and the bottom end wall of the photovoltaic solar panel 3 through the second stepped structure 11.

[0104] Example 6:

[0105] As Figure 14 and Figure 15 shown, the difference between this embodiment and Embodiment 4 is that the other end of the receiving top wall 203 is provided with a third stepped structure 15, and one end of the third stepped structure 15 is provided with a third U-shaped bending structure 16; when the photovoltaic solar panel 3 is installed into the slot structure 2, a fifth glue overflow space 17 is formed between the receiving top wall 203 and the top end wall of the photovoltaic solar panel 3 through the third stepped structure 15.

[0116] Example 12:

[0117] As shown Figure 24 in the figure, the difference between this embodiment and Embodiment 9 is that the second connection end is connected to the other end of the receiving bottom wall 201 through a fourth U-shaped bending structure 20.

[0118] Example 13:

[0119] Those skilled in the art can understand this embodiment as a more specific illustration of Embodiments 1 to 12.

[0120] This embodiment provides a roll-formed profile, including a profile body, which is prepared by roll forming. The set structure is a steel special-shaped roll-formed profile with a U-shaped slot, a glue overflow structure (glue overflow space, for example: glue overflow step / glue overflow groove / glue overflow flange), a support cavity, and a double-layer folding assembly structure. Using this roll-formed profile, after cutting an angle at both ends, corner connectors, fasteners, etc. are spliced at the corners of 4 frames to form a frame. A binder (such as structural glue, sealant, etc.) is provided in the U-shaped slot of the frame for fixing and sealing between the frame and the solar photovoltaic panel. The frame size can be adjusted in the width and length directions, so as to form photovoltaic modules of different models.

[0121] The structure of the aluminum profile has low material strength. The structure of this embodiment is a roll-formed steel profile processed from a coated steel strip, with very high strength, which can reach 500 MPa, more than twice that of the traditional aluminum profile.

[0122] The roll-formed profile provided by this embodiment mainly includes the following structural series:

[0123] As shown Figures 3 to 13 in FIGS. 19, Structural Series 1, the specific structure is as follows:

[0124] A bent step structure is formed at the slot position, and an L-shaped bending structure is formed on the outer support wall of the support cavity, which is supported under the slot and can form a closed support cavity after contacting the step structure of the slot. The lower part of the slot structure has a glue overflow groove or a gap is reserved for the solar panel after tilting at a certain angle for glue overflow.

[0125] As shownFigures 20 to 24 As shown, Structural Series 2, the specific structure is as follows:

[0126] The bent overflow flange of this structure is arranged on the side wall of the slot, forming a structure with an outer concave and an inner convex. The outer support wall of the support cavity forms a 90-degree bend and then inserts into this flange structure, so that the structure is fixed to form a closed support cavity.

[0127] As Figure 14 and Figure 15 shown, Structural Series 3, the specific structure is as follows:

[0128] There is a bent structure at the upper part of the U-shaped slot. In this embodiment, another schematic diagram is given. In addition to bending downward, a step can be formed first and then bent upward by 180 degrees to form a folding structure, which can achieve the same structural effect.

[0129] As Figures 16 to 18 shown, Structural Series 4, the specific structure is as follows:

[0130] Since the welding of the pre-coated steel strip will cause welding defects, in order to ensure the connection strength of the structure, cold mechanical connection needs to be adopted to avoid the technical problems caused by welding. In this embodiment, roll-pressed bump-type mechanical connection is adopted. At the material stacking position, during the forming process, a roll-pressing die is used. The die is set as a concave-convex structure, and the steel strip material at the folding part is roll-pressed, pressing the material on one side into the material on the other side to form a structure with one side sunken and the other side protruding. This bump-type connection is distributed in the length direction of the profile, which can not only ensure the connection strength of the structure, but also avoid the technical problems caused by welding.

[0131] Example 14:

[0132] As Figure 25 shown, this embodiment provides a roll-pressed profile, including a bottom wall 101, a first side wall 102, a second side wall 103, two receiving bottom walls 201, two receiving side walls 202, and two receiving top walls 203.

[0133] One receiving bottom wall 201, one receiving side wall 202, and one receiving top wall 203 form a first installation groove structure 21, and the other receiving bottom wall 201, the other receiving side wall 202, and the other receiving top wall 203 form a second installation groove structure 22, and the two receiving side walls 202 are connected and arranged.

[0134] The first mounting groove structure 21 is connected to the bottom wall 101 through the first side wall 102, and the second mounting groove structure 22 is connected to the bottom wall 101 through the second side wall 103. The first mounting groove structure 21 and the second mounting groove structure 22 are symmetrically arranged about the center line of the bottom wall 101, and the first side wall 102 and the second side wall 103 are symmetrically arranged about the center line of the bottom wall 101. The roll-formed profile is an overall symmetric structure.

[0135] Further, as Figure 26 shown, one end of the receiving top wall 203 is provided with a second U-shaped bending structure 13 for forming a fourth glue overflow space 14 with the photovoltaic solar panel 3.

[0136] Further, as Figure 27 shown, first step structures 5 are provided on both of the two receiving side walls 202 for forming a first glue overflow space 4 with the photovoltaic solar panel 3, and second step structures 11 are provided on both of the two receiving top walls 203 for forming a third glue overflow space 12 with the photovoltaic solar panel 3.

[0137] As Figure 28 shown, the two photovoltaic solar panels 3 are respectively installed in the first mounting groove structure 21 and the second mounting groove structure 22.
