Existing laminates are generally glued to the plug-in slots of the frames with glue. In order to ensure the firmness of the glue on the laminates, too much glue is generally injected, which causes the glue to overflow easily during the installation of the laminates and cause obstruction to the laminates. Subsequently, manual cleaning of the overflowed glue is required to ensure the effective use area of ​​the laminates, resulting in poor processing convenience of photovoltaic modules and high labor costs and cleaning material costs.

[0003] The purpose of the utility model is to provide a photovoltaic frame beam, a photovoltaic frame and a photovoltaic module to solve the technical problems that glue overflows easily during the assembly of the existing photovoltaic modules, resulting in poor processing convenience of the photovoltaic modules and high labor costs and cleaning material costs.

[0004] In order to solve the above problems, the utility model provides a photovoltaic frame beam, comprising a rectangular base frame and two groups of bearing beam groups, wherein one of the frame beam bodies of the rectangular base frame serves as a first base beam body; the bearing beam group comprises a bearing beam body and a limiting beam body connected to the outer wall of the first base beam body and arranged at intervals along the width direction thereof, a glue blocking beam body is provided at one end of the bearing beam body away from the first base beam body, the glue blocking beam body extends toward one side of the limiting beam body and forms a glue overflow groove with the bearing beam body and the limiting beam body, and forms a glue overflow port with one end of the limiting beam body away from the first base beam body;

[0005] The two groups of the load-bearing beam groups are arranged at intervals along the width direction of the first base beam body, and the limiting beam bodies of the two groups of the load-bearing beam groups are arranged to face each other to form a plug-in groove.

[0006] Optionally, the limiting beam body includes an inclined section and a parallel section along the direction away from the first base beam body. Along the direction away from the first base beam body, the inclined sections of the two limiting beam bodies are inclined toward each other to form a wedge-shaped groove section, and the two parallel sections are parallel to each other to form a limiting groove section.

[0008] Optionally, the glue blocking beam body is parallel to the first base beam body; the parallel section is parallel to the load-bearing beam body, and the distance between the two is consistent with the length of the glue blocking beam body.

[0009] Optionally, the two groups of bearing beams are symmetrically arranged about a mid-vertical plane in the width direction of the first base beam body, and a distance between the two groups of bearing beams is no more than 1 / 2 of the width of the first base beam body.

[0010] Optionally, the rectangular base frame includes two first frame beams facing each other and two second frame beams facing each other, the width of the first frame beams is greater than the width of the second frame beams, and one of the first frame beams serves as the first base beam.

[0015] When the photovoltaic frame beam provided by the utility model is applied to photovoltaic frames and photovoltaic modules, glue can be pre-injected into the plug-in groove before installing the laminate.

[0023] This embodiment provides a photovoltaic frame beam, such as Figure 1 As shown, it includes a rectangular base frame 100 and two groups of load-bearing beam groups 200, one of the frame beams of the rectangular base frame 100 serves as the first base beam 110; the load-bearing beam group 200 includes a load-bearing beam 210 and a limiting beam 220 connected to the outer wall of the first base beam 110 and arranged at intervals along its width direction, and a glue blocking beam 230 is provided at one end of the load-bearing beam 210 away from the first base beam 110, the glue blocking beam 230 extends toward one side of the limiting beam 220 and forms a glue overflow groove 240 with the load-bearing beam 210 and the limiting beam 220, and forms a glue overflow port 250 with the end of the limiting beam 220 away from the first base beam 110; the two groups of load-bearing beam groups 200 are arranged at intervals along the width direction of the first base beam 110, and the limiting beams 220 of the two groups of load-bearing beam groups 200 are arranged facing each other to form a plug-in groove 260.

[0024] This embodiment also provides a photovoltaic frame, including four of the above-mentioned photovoltaic frame beams, the four photovoltaic frame beams are connected end to end in sequence, and the insertion grooves 260 of the four photovoltaic frame beams are arranged facing each other.

[0025] This embodiment further provides a photovoltaic assembly, including a laminate and the above-mentioned photovoltaic frame, wherein the edge of the laminate is plugged into the plug-in groove 260 of the photovoltaic frame.

[0026] The photovoltaic frame beam, photovoltaic frame and photovoltaic module provided in this embodiment, when in use, the rectangular base frames 100 of the four photovoltaic frame beams are connected end to end in sequence to form a rectangular frame, wherein the lengths of the four photovoltaic frame beams can be equal to form a square frame, or the lengths of two opposite photovoltaic frame beams are equal and the lengths of two adjacent photovoltaic frame beams are unequal to form a rectangular frame; the plug-in grooves 260 of the four photovoltaic frame beams are all facing the inside of the rectangular frame, the rectangular laminate is embedded in the rectangular frame, and the four side edges thereof are plugged into the four plug-in grooves 260 one by one to achieve pre-connection, and are bonded to the photovoltaic frame by the glue in the plug-in grooves 260 to form a photovoltaic module.

[0027] Before installing the laminate, glue can be pre-injected into the plug-in slot 260. In order to ensure the firmness of the glue to the laminate, the amount of glue injected is generally large. When the laminate is plugged into the plug-in slot 260, as the laminate is continuously inserted, the glue is squeezed outward by the laminate to fill the gap between the laminate and the slot wall of the plug-in slot 260. The glue flowing to the slot opening of the plug-in slot 260 then flows into the overflow glue slot 240 through the overflow glue port 250 on the same side. The depth of the overflow glue slot 240 is proportional to the thickness of the plug-in slot 260. The depth is close, the depth is deeper, and the glue holding space is larger. At the same time, the position where the supporting beam 210 is connected to the first base beam 110 can be set according to the amount of glue overflow, thereby ensuring that the glue overflow groove 240 can accommodate a larger amount of overflowed glue, reducing the covering of the exposed area of ​​the laminate caused by the overflow of glue, and ensuring the effective use area of ​​the laminate; correspondingly reducing the subsequent manual cleaning operations of the overflowed glue, thereby reducing the labor cost and the cost of cleaning materials, and improving the processing convenience and efficiency of photovoltaic frames and photovoltaic modules.

[0028] Of course, in addition to pre-injecting glue into the insertion groove 260 as mentioned above, the edge of the laminate can also be inserted into the insertion groove 260 first, and then glue is injected into the gap between the laminate and the groove wall of the insertion groove 260. The specific operation sequence is not limited.

[0029] Specifically, in this embodiment, Figure 1 As shown, the limiting beam 220 includes an inclined section 221 and a parallel section 222 in the direction away from the first base beam 110. In the direction away from the first base beam 110, the inclined sections 221 of the two limiting beams 220 are inclined toward each other to form a wedge-shaped groove section 261, and the two parallel sections 222 are parallel to each other to form a limiting groove section 262. The plug-in slot 260 includes a linear limiting groove section 262 and a flared wedge-shaped groove section 261 in the direction close to the first base beam 110. When in use, the laminate is first inserted into the limiting groove section 262 and can be limited in position by the limiting groove section 262, and the end of the laminate is then inserted into the wedge-shaped groove section 261. The larger wedge-shaped groove section 261 can accommodate more glue, which can not only improve the adhesive strength of the glue to the end of the laminate, but also reduce the amount of glue overflow.

[0030] Preferably, in this embodiment, if Figure 1 As shown, the position where the inclined section 221 and the bearing beam body 210 are connected to the first base beam body 110 coincides. The inclined section 221 and the bearing beam body 210 are fixedly connected to one end of the first base beam body 110, and on the basis of ensuring the depth and sol volume of the overflowing glue groove 240, the width of the wedge-shaped groove section 261 is further increased, and the sol volume of the wedge-shaped groove section 261 is further increased accordingly, thereby further ensuring the firmness of the glue to the end of the laminate and reducing the overflow of the glue.

[0031] In this embodiment, Figure 1As shown, the width direction of the glue blocking beam body 230 is consistent with the width direction of the first base beam body 110 ; the parallel section 222 and the bearing beam body 210 are parallel to each other, and the distance between the two is consistent with the length of the glue blocking beam body 230 . The length extension directions of each frame beam, bearing beam 210, limiting beam 220 and glue blocking beam 230 in the rectangular base frame 100 are consistent and parallel to each other. The glue blocking beam 230 is parallel to the first base beam 110. The bearing beam 210 and the parallel section 222 are both extended perpendicular to the first base beam 110, and the spacing between the two along the width direction of the first base beam 110 is approximately equal to the extension length of the glue blocking beam 230 in the width direction. The end face of the glue blocking beam 230 facing away from the bearing beam 210 is approximately coplanar with the wall of the parallel section 222 facing the plug-in groove 260, that is, the grooves formed by the facing end faces of the two glue blocking beams 230 correspond to the grooves of the plug-in groove 260, which can ensure the insertion of the laminate. At the same time, the two glue blocking beams 230 can effectively block the glue flowing outward, so that it can completely flow into the glue overflow groove 240 through the glue overflow port 250, thereby further reducing the overflow of glue.

[0032] Optionally, in this embodiment, the two groups of bearing beam groups 200 are symmetrically arranged about the mid-vertical plane in the width direction of the first base beam body 110, and the spacing between the two groups of bearing beam groups 200 is not greater than 1 / 2 of the width of the first base beam body 110. The two groups of bearing beam groups 200 are located in the middle area in the width direction of the first base beam body 110, and the spacing between the two bearing beam bodies 210 is less than or equal to half of the width of the first base beam body 110, thereby ensuring the bearing stability and firmness of the first base beam body 110 to the two groups of bearing beam groups 200, and correspondingly ensuring the bearing stability of the photovoltaic frame beam to the laminate.

[0033] In this embodiment, a reinforcing rib 270 is connected between one end of the bearing beam 210 away from the first base beam 110 and the edge of the same side in the width direction of the first base beam 110. The reinforcing rib 270 is supported between the bearing beam 210 and the first base beam 110 to improve the position stability of the bearing beam 210 connected to the first base beam 110 and reduce the occurrence of deformation of the bearing beam 210; at the same time, it can also improve the stability of the bearing beam group 200 in carrying the laminate.

[0034] Specifically, in this embodiment, the rectangular base frame 100 includes two first frame beams facing each other and two second frame beams facing each other, the width of the first frame beam is greater than the width of the second frame beam, and one of the first frame beams serves as the first base beam 110. When in use, the two second frame beams with smaller widths are arranged up and down, and the two first frame beams with larger widths are arranged left and right, and the bearing beam group 200 is located on the left or right side of one of the first frame beams. Especially in windy and rainy environments, the laminate applies a downward torque to the second frame beam through the bearing beam group 200, and the second frame beam with smaller width can bear the torque with higher strength, thereby ensuring the bearing stability of the photovoltaic frame beam on the laminate.

[0035] In this embodiment, Figure 1 As shown, the frame beam body relative to the first base beam body 110 in the rectangular base frame 100 is used as the second base beam body 120, and one end of the second base beam body 120 in the width direction is provided with a first connecting beam body 310 extending away from it, and the end of the first connecting beam body 310 away from the second base beam body 120 is connected to the second connecting beam body 320, and the second connecting beam body 320 is parallel to the second base beam body 120, and the second base beam body 120, the first connecting beam body 310 and the second connecting beam body 320 surround a connecting groove 330. The second base beam body 120 and the second connecting beam body 320 are located on the same side of the first connecting beam body 310, and the three together surround the connecting groove 330. When in use, the photovoltaic bracket can be inserted into the connecting groove 330, and then the photovoltaic bracket and the first connecting beam body 310 and the second connecting beam body 320 are connected using bolts and other connecting parts to achieve the connection between the photovoltaic module and the photovoltaic bracket, thereby improving the convenience and stability of the photovoltaic module and ensuring its resistance to harsh environments.

[0036] Preferably, the width of the connection groove 330 is slightly smaller than the width of the photovoltaic bracket, and the photovoltaic bracket can be inserted into the connection groove 330 by interference fit to achieve a relatively stable pre-connection, thereby improving the convenience and stability of subsequent secondary bolt connection. Specifically, connection holes with a diameter of 5 mm can be drilled at 100±2 mm from both ends and in the middle of the first connection beam 310 and the second connection beam 320 in the length direction, respectively, for bolts to pass through for connection.

[0037] Optionally, in this embodiment, if Figure 1As shown, among the four frame beams of the rectangular base frame 100 , the inner walls of the two frame beams adjacent to the first base beam 110 are each provided with two positioning ribs 150 , and the two positioning ribs 150 are arranged at intervals along the width direction of the corresponding frame beam to form positioning grooves 160 . The positioning groove 160 is used for plugging and positioning with the angle code. The two frame beams adjacent to the first base beam 110 are the third base beam 130 and the fourth base beam 140 respectively. The inner walls of both are provided with two positioning ribs 150. The two positioning ribs 150 extend along the length direction of the corresponding base beam, and the two positioning ribs 150 are arranged at intervals along the width direction of the corresponding base beam to form the positioning groove 160. When assembling the photovoltaic frame, two adjacent photovoltaic frame beams can be connected by the angle code. Specifically, the angle code includes two right-angled connecting arms, one of which is plugged into one of the rectangular base frames 100 through one end, and the opposite ends of the connecting arm are plugged into two opposite positioning grooves 160 in a one-to-one manner, thereby realizing the pre-positioning of the connecting arm and the rectangular base frame 100, and then the two are connected for a second time using bolts or the like; similarly, the other connecting arm of the angle code is connected to the other rectangular base frame 100, thereby conveniently realizing the assembly of the photovoltaic frame.

[0038] Specifically, the photovoltaic frame beam can be formed by hot extrusion of aluminum alloy material in one piece, and specifically, the aluminum alloy can be 6005 alloy; during processing, the material is extruded and cut into a fixed length of 6050 (0, +20) mm, and then aged, and the aging process is: 185-195℃*3-4h; then it undergoes sandblasting or shot blasting process, specifically taking sandblasting process as an example, the coarseness of glass sand is 40-80 mesh, and the sandblasting speed is 25-35HZ; then conventional anodizing and other operations are performed.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
