Fixing structure for photovoltaic modules

Abstract

This application relates to a fixing structure for photovoltaic modules. The fixing structure for photovoltaic modules, used to fix photovoltaic modules to purlins, includes a clamping frame, a connecting component, and a padding component. During installation, the clamping frame is first placed above the purlin, keeping it parallel to the purlin. The padding component is then placed between the connecting component and the clamping frame. After the connecting component passes through a slotted hole and connects to the purlin, the padding component is clamped between the connecting component and the clamping frame. The slotted hole design allows the connecting component to slide within it, making it easier for the connecting component to reach its predetermined position and pass through the purlin's connection point in confined spaces. This facilitates the movement and connection of the connecting component. Simultaneously, the padding component prevents the connecting component from sliding or rotating loosely relative to the clamping frame, allowing the connecting component to more stably connect the clamping frame and the purlin.

Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to the mounting structure of photovoltaic modules. Background Technology

[0002] Distributed photovoltaic (PV) modules are commonly secured with aluminum alloy fixing blocks, square nuts, and bolts, or by utilizing the locking holes on the back of the PV module and bolts to secure the PV frame holes. However, these methods require installation from the front of the module, which carries the risk of personnel stepping on the module and causing microcracks. Furthermore, when installing bolts, the mainstream thickness of current module frames (30-35mm) makes it easy for bolts to come loose during insertion into the frame mounting holes.

[0003] Existing technical solutions mainly include double-wing aluminum alloy clamping blocks (middle clamping blocks) and single-wing aluminum alloy clamping blocks (edge ​​clamping blocks). Common crystalline silicon modules are aluminum alloy frame modules, and the fastening method is to use hexagonal screws and square nuts attached to the clamping blocks. When installing conventional module frames using aluminum alloy clamping blocks, the plastic-wing nuts need to be placed into the U-shaped steel channels first. However, the plastic-wing nuts need to be aligned with the holes during installation. When the placement is misaligned and needs to be adjusted by sliding, the square nuts can easily rotate, resulting in a reduction or even detachment of the overlapping surface on the inside of the U-shaped steel. Utility Model Content

[0004] Based on this, it is necessary to address the issue that when using aluminum alloy clamps to install conventional module frames, the plastic wing nuts need to be placed into the U-shaped steel channel first. However, the installation of the plastic wing nuts requires alignment with the holes, and when the placement deviation needs to be adjusted by sliding, it can easily cause the square nuts to rotate, resulting in a reduction or even detachment of the overlapping surface on the inside of the U-shaped steel. Therefore, a fixing structure for photovoltaic modules should be provided.

Then, the padding component is placed between the connecting component and the clamping frame. The connecting component passes through the slotted hole and connects to the purlin.

[0043] See Figure 1 , Figure 1 A schematic diagram of the fixing structure 10 of a photovoltaic module according to an embodiment of this application is shown. (See attached diagram.) Figure 1 and Figure 2 An embodiment of this application provides a photovoltaic module fixing structure 10 for fixing a photovoltaic module 20 to a purlin 21, including a clamping frame 100, a connecting component 200, and a padding component 300.

[0044] In the aforementioned photovoltaic module fixing structure 10, one end of the clamping frame 100 clamps the photovoltaic module 20, and the other end has a strip-shaped through hole 100a. The length direction of the strip-shaped through hole 100a is the same as the extension direction of the clamping frame 100. (See reference...) Figure 2 The connecting component 200 passes through the strip-shaped through-hole 100a and is connected to the purlin 21. The padding component 300 is padded between the connecting component 200 and the clamping frame 100. Specifically, the opening direction of the strip-shaped through-hole 100a is perpendicular to the photovoltaic module 20, that is, the axis of the connecting component 200 is perpendicular to the photovoltaic module 20.

[0045] During the installation process of the aforementioned photovoltaic module fixing structure 10, the clamping frame 100 is first placed above the purlin 21, and the clamping frame 100 is kept parallel to the purlin 21. The clamping frame 100 can clamp the photovoltaic module first, or the photovoltaic module can be clamped after the clamping frame 100 and the purlin 21 are connected by the connecting component 200. The padding component 300 is then placed between the connecting component 200 and the clamping frame 100. After the connecting component 200 passes through the strip-shaped through hole 100a and is connected to the purlin 21, the padding component 300 is clamped between the connecting component 200 and the clamping frame 100. The design of the strip-shaped through hole 100a allows the connecting component 200 to slide within it, making it easier for the connecting component 200 to reach the predetermined position in a narrow space and pass through the connection position of the purlin 21. This makes the movement and connection of the connecting component 200 more convenient. At the same time, the padding component 300 prevents the connecting component 200 from sliding or rotating loosely relative to the clamping frame 100, thereby enabling the connecting component 200 to connect the clamping frame 100 and the purlin 21 more stably.

[0046] See Figure 1 In one embodiment, the connecting assembly 200 includes a first structural member 210 and a second structural member 220. The first structural member 210 includes a rod 211 and a head 212. The rod 211 passes through the strip-shaped through hole 100a and the purlin 21, and the head 212 abuts against the side of the clamping frame 100 opposite to the purlin 21. The strip-shaped through hole 100a has a constriction structure that restricts the head from dislodging towards the purlin side. (See reference...) Figure 2 The second structural member 220 abuts against the side of the purlin 21 away from the clamping frame 100, and the padding assembly 300 is placed between the first structural member 210 and the clamping frame 100.

[0047] In this embodiment, after the rod 211 passes through the padding assembly 300 and the clamping frame 100 in sequence, the rod 211 can be slid in the strip-shaped through hole 100a to the position corresponding to the connection position of the purlin 21. During this process, the head 212 is located on the side of the clamping frame 100 away from the purlin 21 to prevent the first structural member 210 from falling off the clamping frame 100. Then the rod 211 passes through the purlin 21 and connects the second structural member 220 to the end of the rod 211 away from the head 212, thereby connecting the clamping frame 100 and the purlin 21. The padding assembly 300 prevents the head 212 from rotating relative to the clamping frame 100, ensuring that the connecting assembly 200 can stably connect the clamping frame 100 and the purlin 21.

[0048] In this embodiment, the first structural member 210 is one of a screw, rivet, expansion rod, or bolt, and the second structural member 220 is one of a snap-fit ​​sleeve or nut. The first structural member 210 passes through the second structural member 220 and is snap-fitted or threadedly connected to the second structural member 220. The specific forms of the first structural member 210 and the second structural member 220 are not limited here.

[0049] In other embodiments, the first structural member 210 is simply a threaded rod, and the first structural member 210 is threadedly engaged with the strip-shaped through hole 100a and the purlin 21.

[0050] See Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the padding assembly 300 includes a ring 310 and a plurality of deformable strips 320. The ring 310 is located between the clamping frame 100 and the head 212. The plurality of deformable strips 320 are arranged circumferentially around the ring 310 and connected to the side of the ring 310 opposite to the head 212. The deformable strips 320 pass through the strip-shaped through hole 100a and the purlin 21, and the end of the deformable strip 320 opposite to the ring 310 is clamped between the second structural member 220 and the purlin 21, so that the deformable strip 320 is angularly deformed, that is, the end of the deformable strip 320 opposite to the ring 310 bends away from the axis of the ring 310.

[0051] In this embodiment, after the rod 211 passes through the ring 310, the clamping frame 100, and the purlin 21 in sequence, a plurality of deformable strips 320 are arranged around the circumference of the rod 211, so that the deformable strips 320 are located between the rod 211 and the side wall of the strip-shaped through hole 100a, and between the rod 211 and the purlin 21, thereby causing the rod 211 to abut against the strip-shaped through hole 100a and the purlin 21, preventing the rod 211 from rotating, and at the same time, the first After the second structural member 220 is connected to one end of the rod 211 that passes through the purlin 21, the deformable strip 320 deforms, so that the end of the deformable strip 320 away from the ring 310 is clamped between the second structural member 220 and the purlin 21. The deformable strip 320 is placed between the second structural member 220 and the purlin 21 to prevent the second structural member 220 from rotating, and to ensure that the entire connecting assembly 200 stably connects the clamping frame 100 and the purlin 21.

[0052] See Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the padding component 300 is provided with multiple sets of protrusions that abut against the clamping frame 100.

[0053] In another embodiment, the padding assembly 300 is provided with multiple sets of protrusions that abut against the purlin 21.

[0054] In yet another embodiment, the padding assembly 300 is provided with a plurality of protrusions that abut against the clamping frame 100 and the purlin 21.

[0055] In the above embodiment, the protruding spikes abut against the clamping frame 100 and the purlin 21. Specifically, the abutment method involves piercing the surfaces of the clamping frame 100 and the purlin 21, thereby ensuring that the padding component 300 can stably maintain its position around the axis of the rod portion 211 without rotation. This guarantees that the connecting component 200 will not rotate, thus improving the stability of the connecting component 200. At the same time, the protruding spikes pierce the surfaces of the clamping frame 100 and the purlin 21, achieving grounding connection between the photovoltaic module fixing structure 10 and the purlin 21.

[0056] See Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the ring portion 310 is provided with a plurality of first protrusions 330 on the side opposite to the head 212. The first protrusions 330 abut against the inner wall surface of the narrowed structure of the strip-shaped through hole 100a of the clamping frame 100. The first protrusions 330 pierce the oxide layer of the inner wall surface of the narrowed structure of the strip-shaped through hole 100a of the clamping frame 100 to achieve grounding and ensure that the head 212 and the rod portion 211 do not rotate relative to each other, thereby making the connection between the connecting frame and the purlin 21 stable.

[0057] See Figure 1 , Figure 3 as well as Figure 4In one embodiment, the deformable strip 320 is provided with a plurality of second protrusions 340 at one end away from the ring portion 310. The second protrusions 340 abut against the side of the purlin 21 away from the head 212. The second protrusions 340 pierce the surface of the purlin 21 to achieve grounding and conduction between the photovoltaic module frame and the purlin, ensuring that the second structural member 220 does not rotate relative to each other, thereby making the connection between the frame and the purlin 21 stable.

[0058] See Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the deformable strip 320 includes a through portion 321, a deformable portion 322, and a puncture portion 323 connected in sequence. The end of the through portion 321 facing away from the deformable portion 322 is connected to the ring portion 310. The through portion 321 passes through the strip-shaped through hole 100a and the purlin 21. The puncture portion 323 is held between the second structural member 220 and the purlin 21. The deformable portion 322 can be bent and deformed to make the through portion 321 and the puncture portion 323 form an angle.

[0059] In this embodiment, multiple through-holes 321 surround the circumference of the rod 211, thereby padding between the rod 211 and the side wall of the strip-shaped through hole 100a, and between the rod 211 and the purlin 21. During the tightening of the second structural member 220, the second structural member 220 abuts against the piercing part 323. Since the through-holes 321 are fixed, the movement of the piercing part 323 causes the deformable part 322 to bend and deform. Finally, the piercing part 323 is padding between the second structural member 220 and the purlin 21. At this time, the piercing part 323 and the through-holes 321 form an angle.

[0060] Preferably, after the second structural member 220 is fastened, the piercing part 323 and the penetrating part 321 form a 90° angle.

[0061] Preferably, the deformable strip 320 is an elastic sheet-like strip. During the tightening of the second structural member 220, the deformable part 322 bends, the second structural member 220 loosens, and the deformable part 322 springs back.

[0062] See Figure 1 , Figure 3 , Figure 4 as well as Figure 6In one embodiment, a third protrusion 350 is provided on the side of the ring portion 310 near the head 212. The third protrusion 350 abuts against the head 212, thereby causing the first protrusion 330 and the third protrusion 350 on both sides of the ring portion 310 to pierce the clamping frame 100 and the head 212 respectively, achieving grounding and making the connection between the head 212 and the clamping frame 100 more stable and secure. A plurality of fourth protrusions are provided on the end of the deformable strip 320 away from the ring portion 310. The second protrusion 340 and the fourth protrusion are located on both sides of the deformable strip 320 respectively. The fourth protrusion abuts against the second structural member 220, causing the second protrusion 340 and the fourth protrusion on both sides of the deformable strip 320 to pierce the purlin 21 and the second structural member 220 respectively, thereby making the connection between the purlin 21 and the second structural member 220 more stable and secure. The aforementioned first protrusion 330, second protrusion 340, third protrusion 350, and fourth protrusion enable lightning protection conduction between the connecting frame, connecting component 200, and purlin 21.

[0063] In another embodiment, reference Figure 5 The ring portion 310 is located between the clamping frame 100 and the purlin 21. Multiple deformable strips 320 are arranged circumferentially around the ring portion 310 and connected to the side of the ring portion 310 opposite to the head 212. The deformable strips 320 pass through the purlin 21, with the end of the deformable strip 320 opposite to the ring portion 310 clamped between the second structural member 220 and the purlin 21, causing the deformable strip 320 to deform at an angle, i.e., the end of the deformable strip 320 opposite to the ring portion 310 is away from the axis of the ring portion 310. The first protrusion 330 abuts against the purlin 21, and the third protrusion 350 abuts against the bottom surface of the clamping frame 100, thereby causing the first protrusion 330 and the third protrusion 350 on both sides of the ring portion 310 to pierce the surface of the purlin 21 and the clamping frame 100 respectively, thus making the purlin 21 and the clamping frame 100 grounded and more stably connected and secure.

[0064] See Figure 1 and Figure 2 In one embodiment, the clamping frame 100 includes a clamping portion 110 and a connecting portion 120 connected to each other. The clamping portion 110 is used to clamp the photovoltaic module 20, and the connecting portion 120 has a strip-shaped through hole 100a at one end opposite to the clamping portion. The length direction of the strip-shaped through hole 100a is the same as the extension direction of the connecting portion 120. In this embodiment, the clamping portion 110 clamps the photovoltaic module 20, and the connecting component 200 passes through the strip-shaped through hole 100a in the connecting portion 120, thereby connecting the connecting portion 120 to the purlin 21.

[0065] See Figure 1 and Figure 2In one embodiment, the connecting part 120 includes a connecting frame 121, the clamping part 110 is connected to the connecting frame 121, and a strip-shaped through hole 100a is provided at one end of the connecting frame 121 away from the clamping part 110. The first structural member 210 passes through the strip-shaped through hole 100a, and the head 212 is located inside the connecting frame 121. The extension direction of the strip-shaped through hole 100a is parallel to the extension direction of the connecting frame 121. The first structural member 210 passes through the strip-shaped through hole 100a, and its head 212 is located inside the connecting frame 121, thereby preventing the first structural member 210 from falling off the connecting part 120. It can also drive the first structural member 210 to move along the extension direction of the strip-shaped through hole 100a to the position corresponding to the purlin 21 to be installed, and then pass through the purlin 21. Finally, the second structural member 220 is tightened, and its head 212 abuts against the inside of the connecting frame 121. The second structural member 220 abuts against the purlin 21, thereby connecting the clamping frame 100 and the purlin 21 through the connecting assembly 200.

[0066] In this application, the connecting portion 120 is a C-shaped structure with its opening facing the purlin 21, and the cross-section of the connecting portion 120 is square. The purlin 21 is a C-shaped structure with its opening facing away from the connecting portion 120, and the cross-section of the purlin 21 is square. The above structure ensures that the position where the ring portion 310 pierces the connecting portion 120 is located on the inner wall of the connecting portion 120, and the position where the deformable strip 320 pierces the purlin 21 is located on the inner wall of the purlin 21. The piercing position is not exposed externally. During the 25-year service life of the photovoltaic power station, corrosion caused by external exposure of the piercing point is significantly reduced, resulting in a longer service life and effectively ensuring conductivity.

[0067] See Figure 1 and Figure 2 In one embodiment, the connecting portion 120 further includes a beam plate 122, the two ends of which are respectively connected to the two opposing inner walls of the connecting frame 121, and the extending direction of the beam plate 122 is parallel to the extending direction of the connecting frame 121. Since the connecting portion 120 has a strip-shaped through hole 100a, the side walls on both sides of the strip-shaped through hole 100a may approach each other under the action of extrusion force, causing the connecting frame 121 to deform. Therefore, a beam plate 122 is provided inside the connecting frame 121, so that the two ends of the beam plate 122 are connected to the two opposing inner walls of the connecting frame 121, thereby preventing the connecting frame 121 from deforming.

[0068] See Figure 1 and Figure 2In one embodiment, the connecting portion 120 further includes an abutment plate 123. The extending direction of the abutment plate 123 is parallel to the extending direction of the connecting frame 121. One end of the abutment plate 123 is connected to the outer wall of the connecting frame 121, and the abutment plate 123 is flush with the end of the connecting frame 121 opposite to the clamping portion 110. The abutment plate 123 abuts against the purlin 21. This extends the abutment surface between the connecting portion 120 and the purlin 21, making the abutment between the clamping frame 100 and the purlin 21 more stable and less prone to tipping over and damaging the photovoltaic module 20.

[0069] See Figure 1 and Figure 2 In one embodiment, the clamping part 110 includes a connecting plate 111 and a clamping hook 112. One end of the connecting plate 111 is connected to the clamping hook 112, and the other end is connected to the connecting part 120, and the photovoltaic module 20 is clamped between the clamping hook 112 and the connecting plate 111.

[0070] Specifically, the connecting plate 111 is a long strip, and the clamping hook 112 extends toward the photovoltaic module 20. The clamping hook 112 is also strip-shaped, and the strip-shaped clamping hook 112 extends along the extension direction of the clamping frame 100.

[0071] Specifically, the photovoltaic module 20 is limited in three directions by the connecting plate 111, the clamping hook 112 and the connecting part 120. Two photovoltaic module fixing structures 10 are respectively provided on both sides of the photovoltaic module 20, so that the photovoltaic module 20 can be limited between the two photovoltaic module fixing structures 10, thereby fixing the photovoltaic module 20.
