Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a reinforcement device for a photovoltaic component. Background Art

[0002] With the continuous development of the photovoltaic industry, more and more photovoltaic products are used on industrial and commercial roofs, and more products combining metal corrugated sheets and photovoltaic modules have appeared on the market. However, due to structural waterproofing considerations, punching mechanical fixation is rarely used on corrugated sheets. Most products are only fixed with structural adhesives or other glues.

[0003] Structural adhesives are a type of chemical fixing method that is widely used in the construction industry. Their effectiveness for outdoor use is generally around 8 to 10 years. Metal roofs heat up quickly in the summer and cool down quickly in the winter. As the years of use increase, the durability of structural adhesives will decrease rapidly. In many places, there have even been incidents of adhesive structural parts falling off and injuring people.

[0004] While photovoltaic modules are simpler, lighter, and thinner than other building components, the safety risks of structural adhesives, which can be compromised by extreme weather, remain a significant safety hazard. Furthermore, the application of structural adhesives is concealed, and their quality relies heavily on the skill of the workers. Post-process inspections are difficult, further exacerbating safety uncertainties.

[0005] Therefore, how to prevent photovoltaic modules from falling off relative to the metal profiled sheet is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] In the description of the present invention, it should be understood that the terms "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0041] The purpose of the utility model is to provide a reinforcement device for a photovoltaic module, which can prevent the photovoltaic module from falling off relative to the metal profiled plate.

[0042] See also Figure 1 and Figure 2 To achieve the above-mentioned purpose, the present invention provides a photovoltaic module reinforcement device, which includes a plurality of photovoltaic modules 100, tile hanging strips 200 and a clamp base 300.

[0043] Several photovoltaic assemblies 100 each include a photovoltaic panel and a metal tile located at the bottom of the photovoltaic panel. A first gap 110 is provided between adjacent photovoltaic panels. The metal tiles each include an extension portion 120 that can extend outward along the first gap 110. Typically, the extension direction of the extension portion 120 is perpendicular to the photovoltaic panel and the extension portion 120 is a bendable metal structure.

[0044] The tile hanging strips 200 are connected to the extensions 120 in the same first gap 110 through the supports 210 to fix adjacent metal tiles. Colloid is provided between the photovoltaic panel and the extensions 120 .

[0045] Among them, the support 210 can adopt a Z-shaped structure, which includes two horizontal parts and one vertical part. After one horizontal part of the support 210 is attached to the tile hanging strip 200, a detachable connection with the tile hanging strip 200 is achieved through screws 220. At the same time, the vertical part of the installed support 210 is located between adjacent photovoltaic panels, so that the support 210 can be connected to the extension part 120 in the same first gap 110, so that adjacent metal tiles are fixed through the support 210. Considering the stability of the connection between the extension part 120 and the support 210, the part of the extension part 120 that exceeds the vertical part can be bent along the outer wall of the support 210 toward the other horizontal part, so that the extension part 120 and the vertical part and one horizontal part of the support 210 are approximately a whole, which is convenient for space saving.

[0046] The clamp base 300 includes a mounting portion 310 located above the photovoltaic panel, and a clamp body 320 mounted above the first gap 110 through the mounting portion 310. The clamp body 320 is provided with a receiving groove 330 for accommodating the extension portion 120. The connecting member 400 can be passed through the receiving groove 330 to limit the movement of the extension portion 120 relative to the clamp base 300.

[0047] Aluminum profiles are widely used as building materials for exterior structures of buildings. They will oxidize in the air to form a dense oxide film to prevent the internal parts from being oxidized and failing. The material is also easier to process and can be processed into any corresponding shape. Considering the use scenario of the clamp base 300, the clamp base 300 can be made of aluminum, and the connector 400 can be made of stainless steel screws. Stainless steel is a steel component that is not easily corroded under outdoor conditions. The fixing effect of bolts made of stainless steel is more durable than that of ordinary steel bolts.

[0048] The support 210 is connected to the extension portion 120 in the same first gap 110 to fix adjacent metal tiles. By passing the connecting piece 400 through the receiving groove 330 of the clamp base 300 and pressing the extension portion 120 located in the receiving groove 330, the movement of the extension portion 120 can be limited so that the position of the clamp base 300 is relatively fixed. The mounting portion 310 provided on the clamp base 300 is located above the photovoltaic panel to press the photovoltaic panel, which can prevent the photovoltaic assembly 100 from falling off relative to the metal corrugated sheet, thereby improving the safety of the pure adhesive photovoltaic assembly 100 after the durability of the structural adhesive is insufficient or fails.

[0049] See also Figure 3 、 Figure 7 and Figure 8 In this embodiment, the mounting portion 310 is provided with a accommodating cavity 311 extending along the length direction of the clamp base 300, and a first opening 312 is provided at the bottom of the accommodating cavity 311. The top of the rubber strip 500 is installed in the accommodating cavity 311, and the bottom of the rubber strip 500 is attached to the photovoltaic panel. The first opening 312 includes a larger first end and a smaller second end. The first end is located on the side of the first opening 312 away from the accommodating cavity 311 to limit the rubber strip 500 from escaping from the accommodating cavity 311 along the first opening 312, thereby improving the stability of the rubber strip 500 after installation. At the same time, considering the needs in actual applications, the length of the rubber strip 500 should be greater than the length of the clamp base 300 to prevent the clamp base 300 from contacting the photovoltaic panel.

[0050] Among them, the rubber strip 500 is provided with a hole 510 extending along its own length direction, so that when the clamp base 300 presses the rubber strip 500, the bottom of the rubber strip 500 expands to both sides. The rubber strip 500 can be made of EPDM rubber, and is applied between the glass and the metal through the rubber strip 500 to play a buffering and waterproofing role, avoiding the aluminum alloy clamp base 300 from directly contacting the photovoltaic panel, and avoiding the different thermal expansion and contraction coefficients of metal parts and glass parts causing component rupture.

[0051] See also Figure 5 and Figure 6 In this embodiment, a first threaded hole 321 is provided on one side of the clamp body 320 for rotatably connecting the connecting member 400. The length of the connecting member 400 in the axial direction of the first threaded hole 321 is greater than or equal to the distance between the two sides of the accommodating groove 330 in the axial direction of the first threaded hole 321, so that the connecting member 400 pushes the extension part 120 to the other side of the clamp body 320.

[0052] The first threaded hole 321 is a hole formed on one side of the clamp body 320, and the number of the first threaded holes 321 is multiple and evenly arranged along the length direction of the clamp body 320. The first threaded holes 321 can be tightened with a standard screw of the corresponding diameter. By using the connector 400 of the stainless steel screw and the first threaded hole 321, the connector 400 can be rotated to the inside of the accommodating groove 330, and the axial direction of the connector 400 is consistent with the first threaded hole 321. When the connector 400 is rotated to fit the extension 120 located in the accommodating groove 330, the connector 400 continues to be rotated. Under the pressure of the connector 400, the extension 120 is pressed against the inner wall of one side of the clamp body 320. Continuing to apply pressure will cause the extension 120 to deform until the extension 120 produces irreversible deformation, so as to avoid relative movement between the clamp body 320 and the extension 120.

[0053] It should be noted that the length of the connecting member 400 in the axial direction of the first threaded hole 321 is greater than or equal to the distance between the two sides of the accommodating groove 330 in the axial direction of the first threaded hole 321, so as to ensure that the end of the connecting member 400 can press the extension part 120 to the inner wall of one side of the clamp body 320. The length of the connecting member 400 can also be adjusted according to actual needs to achieve the above purpose.

[0054] In addition, the clamp body 320 is also provided with a first protrusion 340, which is located on the side of the accommodating groove 330 away from the first threaded hole 321. Through the first protrusion 340, the extension part 120 can first abut against the first protrusion 340 before contacting the inner wall of one side of the clamp body 320. The contact area between the first protrusion 340 and the extension part 120 is smaller, so that the pressure at the contact point between the first protrusion 340 and the extension part 120 is increased, which can accelerate the irreversible deformation process of the extension part 120, thereby saving the intensity of manual labor and improving construction efficiency.

[0055] As one of the embodiments, the first protrusion 340 can be a circular protrusion, the first protrusion 340 corresponds to the first threaded hole 321 one by one, and the inner diameter of the first protrusion 340 is larger than the inner diameter of the first threaded hole 321, so that the first protrusion 340 accelerates the deformation process of the extension part 120 while avoiding the pressure of the connecting part 400 on the extension part 120 and the supporting force of the first protrusion 340 on the extension part 120 offsetting each other. The two forces with opposite extension directions and non-collinearity can accelerate the twisting of the deformable object.

[0056] In addition, the first protrusion 340 can be a long strip-shaped protrusion, that is, the extension direction of the first protrusion 340 and the axis of the first threaded hole 321 are perpendicular to each other, which can also achieve the above effect.

[0057] See also Figure 4 and Figure 9 In this embodiment, considering the protection of the connecting piece 400 and the rubber strip 500 in order to extend the service life of the clamp body 320, the clamp base 300 is provided with second protrusions 350 at both ends on the axis of the first threaded hole 321, and the second protrusions 350 are located at the top of the mounting portion 310, and the second protrusions 350 extend in the horizontal direction. The reinforcement device of the photovoltaic component 100 also includes a clamp cover 600, and the clamp cover 600 is a bent structure. The inner walls on both sides of the clamp cover 600 on the axis of the first threaded hole 321 are provided with third protrusions 610. The third protrusions 610 are set at the same height, and the distance between the two third protrusions 610 on the axis of the first threaded hole 321 is less than the distance between the two opposite ends of the second protrusions 350 on the axis of the first threaded hole 321, so that the third protrusion 610 is clamped at the bottom of the second protrusion 350, so that the clamp cover 600 can be detachably connected to the clamp base 300.

[0058] It should be noted that the full-length clamp cover plate 600 strengthens the weak link of the roof waterproofing, and the tiny gaps in the tile roof can be patched with glue in the gap under the clamp cover plate 600, which greatly reduces the possibility of roof leakage and also increases the durability of the stainless steel screw. The clamp cover plate 600 can be extruded from aluminum alloy or bent from metal sheets to reduce production costs.

[0059] In summary, when installing the reinforcement device of the photovoltaic module 100, first, the rubber strip 500, which is slightly longer than the length of the clamp base 300, is passed through the corresponding accommodating cavity 311 of the clamp base 300, and the stainless steel screw is initially screwed into the first threaded hole 321; the assembled clamp base 300 is placed above the first gap 110 so that the extension 120 is located in the accommodating groove 330, and pressure is applied to the clamp base 300 so that the rubber strip 500 presses the photovoltaic module 100, and at the same time, the stainless steel screw on the clamp base 300 is tightened until the extension 120 is tightened and an irreversible deformation occurs; according to the above installation method, The clamp base 300 of the same roof is installed on the entire roof according to the set spacing, ensuring that at least two sides of each photovoltaic module 100 are clamped by the clamp base 300; the clamp cover 600 is buckled on the clamp base 300 in the manner of the third protrusion 610 being snapped onto the second protrusion 350 until the installation is completed. The clamp base 300 and the clamp cover 600 adopt a simple design to minimize the change to the overall effect of the roof. The clamp base 300 is firmly fixed in place by the characteristic that the metal plate does not recover after deformation after being tightened by the stainless steel screw, and the fixing effect can be achieved for a long time.

[0060] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0062] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
