Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panel installation and fixing, and more specifically, to a photovoltaic panel installation component and a photovoltaic panel device. Background Technology

[0002] With the increasing global demand for renewable energy, solar photovoltaic power generation, as a clean and renewable energy technology, has been widely applied. As the core component of a solar power generation system, the stability and reliability of photovoltaic modules directly affect the performance and lifespan of the entire system.

[0003] In existing photovoltaic (PV) module installation technologies, a combination of frame and frame clamps is typically used for fixing. This installation method can meet basic fixing requirements when PV modules are installed horizontally. However, in practical applications, PV modules often need to be installed at an angle or vertically depending on the conditions of the installation site and the angle of sunlight. In this case, the existing mating structure between the frame and the PV panel will not result in relative displacement. However, some existing technologies for the mating of the PV module frame and frame clamps have significant drawbacks.

[0004] Specifically, when photovoltaic modules have a vertical tilt angle, or are even installed vertically, the stability of the fit between the frame and the frame clamping block is severely affected. Under the influence of gravity, the photovoltaic module is prone to relative movement, especially in the vertical direction. This relative movement not only causes the installation position of the photovoltaic module to shift, but may also damage the structure of the photovoltaic module, reducing its service life. Furthermore, the existing technology for fitting the frame and frame clamping block requires multiple adjustments and calibrations during installation, which is complex and time-consuming. This not only increases installation costs but also reduces installation efficiency, hindering the implementation of large-scale photovoltaic module installation projects. Utility Model Content

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application.

[0031] like Figures 1 to 4As shown, the photovoltaic panel mounting assembly of this embodiment includes a frame structure 10 and a pressure plate structure 20. The frame structure 10 includes a photovoltaic panel mounting portion and a pressure plate mating portion, with the opening directions of the photovoltaic panel mounting portion and the pressure plate mating portion being opposite. The pressure plate structure 20 includes a connected pressure plate mounting mating portion 21, an inner wall pressing mating portion 22, and an outer wall pressing mating portion 23. The inner wall pressing mating portion 22 is located within the pressure plate mating portion, and the outer wall pressing mating portion 23 mates with a portion of the outer wall of the photovoltaic panel mounting portion. The pressure plate structure 20 and the frame structure 10 have mutually cooperating X-axis direction limiting structures, Y-axis direction limiting structures, and Z-axis direction limiting structures.

[0032] Applying the technical solution of this embodiment, the pressure plate structure 20 cooperates with the frame structure 10. The pressure plate structure 20 has an inner wall pressing fit part 22 and an outer wall pressing fit part 23, thus the pressure plate structure 20 provides a better pressing effect on the frame structure 10. The pressure plate structure 20 and the frame structure 10 have mutually cooperating X-axis direction limiting structures, Y-axis direction limiting structures, and Z-axis direction limiting structures, which can prevent relative displacement between the pressure plate structure 20 and the frame structure 10 in three-dimensional space along the X-axis, Y-axis, and Z-axis directions. The technical solution of this embodiment effectively solves the problem of relative displacement between the pressure plate structure and the frame structure in the prior art.

[0033] It should be noted that, as Figure 3 As shown, in the technical solution of this embodiment, the X-axis direction, Y-axis direction and Z-axis direction are all perpendicular to each other.

[0034] like Figure 2 and Figure 3As shown, in the technical solution of Embodiment 1, the frame structure 10 includes a first frame bending plate 11, a second frame bending plate 12, and a third frame bending plate 13. The first frame bending plate 11 and the third frame bending plate 13 are respectively connected to opposite sides of the second frame bending plate 12, forming a pressure plate mating part. The first frame bending plate 11 is parallel to the plane formed by the X-axis and Z-axis, the second frame bending plate 12 is parallel to the plane formed by the Y-axis and Z-axis, and the first frame bending plate 11 and the third frame bending plate 13 are parallel. The inner wall pressing mating part 22 includes a first pressure plate 221 and a second pressure plate 222. The first side of the first pressure plate 221 is connected to the first side of the second pressure plate 222. The first pressure plate 221 mates with the first frame bending plate 11, and the second pressure plate 222 mates with the second frame bending plate 12. The first pressure plate 221 is parallel to the first frame bending plate 11, and the second pressure plate 222 is parallel to the second frame bending plate 12. This structure results in a large mating area between the frame structure 10 and the pressure plate structure 20, and allows for the formation of limiting structures in multiple directions. For example, the first pressure plate 221 limits the first frame bending plate 11 in the Y-axis direction, and the second pressure plate 222 limits the second frame bending plate 12 in the X-axis direction. It should be noted that the side of the first frame bending plate 11 away from the second frame bending plate 12 has a limiting flange, the height of which is higher than the thickness of the first pressure plate 221. Alternatively, in other embodiments, the height of the limiting flange can be equal to or lower than the thickness of the first pressure plate 221. The limiting flange also limits the frame structure 10 in the X-direction.

[0035] like Figure 2 and Figure 3 As shown, in the technical solution of Embodiment 1, the side of the first frame bending plate 11 facing the first pressure plate 221 has a first protrusion 14, and the first pressure plate 221 has a first limiting hole 223 that cooperates with the first protrusion 14. The first protrusion 14 passes through the first limiting hole 223. The first protrusion 14 can be a protruding plate, a boss, and / or a protrusion; in this embodiment, it is a protruding plate. The first limiting hole 223 can be a limiting groove that does not penetrate the thickness direction of the first pressure plate 221 or a limiting hole that penetrates the thickness direction of the first pressure plate 221. In this embodiment, the first limiting hole 223 is a limiting hole that penetrates the thickness direction of the first pressure plate 221. The width of the protruding plate is the same along the X-axis direction. The height of the first protrusion 14 is greater than the thickness of the first pressure plate 221. In this embodiment, the height of the first protrusion 14 is 1.1 to 1.6 times the thickness of the first pressure plate 221, so that the first protrusion has a better limiting effect on the frame structure 10 in the Z-axis direction. There are two first protrusions 14 and two first limiting holes 223. The two first protrusions 14 are attached to the common frame of the two first limiting holes 223.

[0036] like Figure 2 As shown, in the technical solution of Embodiment 1, the second frame bending plate 12 has a bending boss. The platform surface of the bending boss protrudes outward toward the second pressure plate 222 and abuts against the second pressure plate 222. The bending boss increases the elastic deformation of the frame structure 10, so that the frame structure 10 and the pressure plate structure 20 can compensate for the external force through elastic deformation. In addition, the elastic deformation of the frame structure 10 and the pressure plate structure 20 also provides many conveniences for installation. For example, when there are multiple bosses, some elastic deformation can facilitate installation and reduce insufficient fitting accuracy caused by processing errors.

[0037] like Figure 2 As shown, in the technical solution of Embodiment 1, the frame structure 10 further includes a fourth frame bending plate 16 and a fifth frame bending plate 17. The opposite sides of the fourth frame bending plate 16 are connected to the fifth frame bending plate 17 and the third frame bending plate 13, respectively. The third frame bending plate 13, the fourth frame bending plate 16, and the fifth frame bending plate 17 form a photovoltaic panel mounting part. The above structure is compact, lightweight, and has good elastic deformation and fixing effect.

[0038] like Figure 2 and Figure 3 As shown, in the technical solution of Embodiment 1, the pressure plate mounting fitting part 21 includes a third pressure plate 211, a fourth pressure plate 212, and a fifth pressure plate 213. The opposite sides of the third pressure plate 211 are connected to the second pressure plate 222 and the fourth pressure plate 212, respectively. The fifth pressure plate 213 is connected to the side of the fourth pressure plate 212 away from the third pressure plate 211. The third pressure plate 211 is parallel to the plane of the Z-axis and X-axis travel. The third pressure plate 211 has fixing holes, and bolts pass through the fixing holes of the third pressure plate 211 to connect with the mounting bracket structure 30. It should be noted that, since the first frame bending plate 11 has a certain thickness, the height of the fourth pressure plate 212 is slightly greater than the height of the second pressure plate 222.

[0039] like Figure 2 As shown, in the technical solution of Embodiment 1, the outer wall pressing and fitting part 23 includes a sixth pressing plate 231 and a seventh pressing plate 232. The sixth pressing plate 231 is connected between the third pressing plate 211 and the seventh pressing plate 232. The sixth pressing plate 231 abuts against the fourth frame bending plate 16, and the seventh pressing plate 232 abuts against the fifth frame bending plate 17. The sixth pressing plate 231 is parallel to the plane formed by the Z-axis and Y-axis, and the seventh pressing plate 232 is parallel to the plane formed by the X-axis and Z-axis. The sixth pressing plate 231 limits the frame structure 10 in the X-axis direction, and the seventh pressing plate 232 limits the frame structure 10 in the Y-axis direction. The above structure is compact and has a good limiting effect.

[0040] like Figure 1 and Figure 2As shown, in the technical solution of Embodiment 1, the photovoltaic panel mounting assembly further includes a mounting frame structure 30, which is connected to the pressure plate mounting mating part 21. The fifth pressure plate 213 is attached to the mounting frame structure 30, and the first frame bending plate 11 is attached to the mounting frame structure 30. The third pressure plate 211 is connected to the mounting frame structure 30 by bolts.

[0041] The difference between the technical solution of Embodiment 2 and the technical solution of Embodiment 1 is that the side of the second frame bending plate 12 facing the second pressure plate 222 has a second protrusion 15, the second pressure plate 222 has a second limiting hole corresponding to the second protrusion 15, and the second protrusion 15 passes through the second limiting hole.

[0042] like Figure 5 As shown, the difference between the technical solution of Embodiment 3 and the solution of Embodiment 1 is that the photovoltaic panel mounting assembly has both a first protrusion 14 and a first limiting hole 223, as well as a second protrusion 15 and a second limiting hole. The above structure further ensures the limiting of the frame structure 10 by the pressure plate structure 20 in the Z-axis direction.

[0043] The difference between the technical solution of Embodiment 4 and Embodiment 1 is that the photovoltaic panel mounting assembly further includes a third protrusion on the side of the seventh pressure plate 232 facing the fifth frame bending plate 17, and a first limiting groove adapted to the third protrusion on the fifth frame bending plate 17; and a fourth protrusion on the side of the sixth pressure plate 231 facing the fourth frame bending plate 16, and a second limiting groove adapted to the fourth protrusion on the fourth frame bending plate 16. The above structure further ensures the limiting of the frame structure 10 by the pressure plate structure 20 in the Z-axis direction. In addition, the cooperation of the protrusion and the groove can also serve a positioning function.

[0044] The difference between the technical solution of Embodiment 5 and the technical solution of Embodiment 1 is that the first pressure plate 221, the first frame bending plate 11 and the mounting frame structure 30 all have through holes, and bolts pass through the first pressure plate 221, the first frame bending plate 11 and the mounting frame structure 30 to connect them, so that the relative displacement of the pressure plate structure 20 and the frame structure 10 can be constrained.

[0045] The difference between the technical solution of Embodiment Six and that of Embodiment One is that the contact surfaces of the pressure plate structure 20 and the frame structure 10 have friction surfaces. These friction surfaces can increase the friction between the pressure plate structure 20 and the frame structure 10, preventing relative displacement between them in the Z-axis direction. For example, the pressure plate structure 20 has multiple protrusions, and the frame structure 10 has multiple concave points, forming a friction surface through the protrusions and concave points.

[0046] The difference between the technical solution of Embodiment 7 and the technical solution of Embodiment 1 is that the first protrusion 14 is a convex plate, and the free end of the convex plate to the root of the convex plate is a trapezoid with gradually increasing width. The first limiting hole is trapezoidal, and the width of the convex plate and the first limiting hole increase in opposite directions, so the fitting accuracy is relatively high. The width of the convex plate extends along the X-axis direction.

[0047] like Figure 6 and Figure 7 As shown, this application also provides a photovoltaic panel device, which includes a photovoltaic panel mounting assembly and a photovoltaic panel 100. The photovoltaic panel mounting assembly is the aforementioned photovoltaic panel mounting assembly, and the photovoltaic panel 100 is mounted on the photovoltaic panel mounting section of the photovoltaic panel mounting assembly.
