Description

Technical Field

[0002] BIPV photovoltaic color steel tiles are a building material that combines building-integrated photovoltaic power generation technology with metal photovoltaic color steel tiles. BIPV color steel tiles incorporate photovoltaic panels onto their surface, giving them the architectural functionality of traditional metal color steel tiles while also harnessing solar power. The photovoltaic panels are integrated onto the surface of the photovoltaic color steel tiles, which are secured to the roof purlins via supports. The design of the supports is particularly critical, considering factors such as strength, wind-uplift resistance, waterproofing, and installation method.

[0003] The existing supports only consider the fixation of photovoltaic color steel tiles. Although they play a fixing role, the connection of the supports to the photovoltaic color steel tiles is a rigid connection. Therefore, in the process of matching the protruding structure of the photovoltaic color steel tiles with the production, the surface of the photovoltaic color steel tiles is easily damaged. In subsequent use, the damaged parts of the photovoltaic color steel tiles are prone to rust, shortening the service life. Utility Model Content

[0043] See Figure 1 , Figure 1 A schematic diagram of the structure of a fixing device 100 for photovoltaic color steel tiles in an embodiment of the present application is shown. The fixing device 100 for photovoltaic color steel tiles provided in an embodiment of the present application is used to install photovoltaic color steel tiles 210. The photovoltaic components are fixed to the location to be installed, such as a roof or a construction plane, through the photovoltaic color steel tiles 210. The fixing device 100 for photovoltaic color steel tiles includes: a base 110, two support arms 120, two elastic clip portions 130 and a support portion 121.

[0044] In the above-mentioned fixing device 100 for photovoltaic color steel tiles, the base 110 is used to connect to the location to be installed. One end of the support arm 120 is connected to the base 110, and the two support arms 120 are opposite and spaced apart along the first direction OX. One end of the elastic clamping portion 130 is connected to the end of the support arm 120 away from the base 110, and the two elastic clamping portions 130 are respectively located on the side of the support arm 120 facing away from each other. The elastic clamping portion 130 can generate elastic deformation along the first direction OX so that the protrusions 212 on both sides of the protruding structure 211 of the photovoltaic color steel tile 210 can be clamped between the elastic clamping portion 130 and the support arm 120. The two ends of the support portion 121 are respectively connected to the two elastic clamping portions 130, and the support portion 121 is used to support the top plate 215 of the protruding structure 211. The first direction OX is perpendicular to the thickness direction of the base 110.

[0045] See Figure 2During the actual installation of the photovoltaic color steel tile fixing device 100, the base 110 is first installed at the location to be installed, and then the photovoltaic color steel tile 210 is placed on the photovoltaic color steel tile fixing device 100. Then, the protruding structure 211 of the photovoltaic color steel tile 210 is moved toward the base 110 so that the top plate 215 of the protruding structure 211 is attached to the side of the support portion 121 facing away from the base 110. During the process of the protruding structure 211 of the photovoltaic color steel tile 210 moving toward the base 110, the protruding portions 212 on both sides of the protruding structure 211 of the photovoltaic color steel tile 210 respectively squeeze the two elastic clamping portions 130, causing the two elastic clamping portions 130 to elastically deform toward each other. Until the top plate 215 is attached to the side of the support portion 121 facing away from the base 110, the protrusion 212 moves to the lower side of the elastic clip 130, that is, the protrusion 212 moves between the elastic clip 130 and the base 110, and the elastic clip 130 is located between the two protruding plates 214, so that the elastic clip 130 can move away from each other and restore their original shape. At this time, the protrusion 212 is clamped between the clamping part and the support arm 120, and the protrusions 212 on both sides of the protruding structure 211 are respectively clamped by two elastic clamping parts 130 arranged along the first direction OX, thereby realizing the limitation of the photovoltaic color steel tile 210 along the first direction OX and the direction perpendicular to the base 110. At the same time, relative to the rigid fixing device, the elastic deformation of the elastic clamping part 130 makes the protrusion 212 of the photovoltaic color steel tile 210 as little as possible from the clamping part during the clamping process, thereby preventing the surface of the photovoltaic color steel tile 210 from being damaged and improving the service life of the photovoltaic color steel tile 210.

[0046] See Figure 2 The first and second connecting plates 132 and 133 are connected to each other at the same time, so that the protrusion 212 can be clamped between the elastic clamping portion 130 and the support arm 120, thereby improving the smoothness of the protrusion 212 in the process of clamping with the elastic clamping portion 130 and protecting the photovoltaic color steel tile 210.

[0047] See Figure 2In one embodiment, the gap between the first connecting plate 132 and the second connecting plate 133 gradually expands in the direction approaching the base 110, so that the first connecting plate 132 and the second connecting plate 133 are as close to each other as possible, so that the force of the first connecting plate 132 and the second connecting plate 133 when generating elastic deformation close to the support arm 120 is reduced as much as possible, and the force of elastic deformation away from the support arm 120 is increased as much as possible, so that the protrusion 212 of the photovoltaic color steel tile 210 is more easily clamped between the first connecting plate 132 and the support arm 120, and the difficulty of the protrusion 212 falling out from between the first connecting plate 132 and the support arm 120 is increased.

[0048] See Figure 1 and Figure 2 In one embodiment, the fixing device 100 of the photovoltaic color steel tile also includes a transition section 140, one end of the transition section 140 is connected to the end of the first connecting plate 132 away from the bending portion 131, and the other end is connected to the end of the support arm 120 away from the base 110, so that there is a gap between the elastic clamping portion 130 and the support arm 120. The gap allows the elastic clamping portion 130 and the support arm 120 to move closer or farther away through the elastic deformation of the transition section 140.

[0049] See Figure 1 and Figure 2 In one embodiment, the transition section 140 protrudes away from the base 110, thereby facilitating the elastic clamping portion 130 and the support arm 120 to move closer or further apart due to the elastic deformation of the transition section 140. Compared to a flat transition section 140 or a transition section that protrudes toward the base 110, the elastic clamping portion 130 and the support arm 120 move closer or further apart in accordance with the distribution of elastic deformation force, thereby facilitating smoother installation of the photovoltaic color steel tile fixture 100. The transition section 140 can be circular, elliptical, or other shapes, and the specific protrusion is not limited.

[0050] In another embodiment, the first connecting plate 132 and the second connecting plate 133 are disposed in parallel.

[0051] See Figure 2 In one embodiment, the distance between the two second connecting plates 133 gradually expands along the thickness direction of the base 110 away from the support portion 121, thereby adapting to the protruding structure 211 of the photovoltaic color steel tile 210, and at the same time allowing the protruding structure 211 and its protruding portion 212 to be smoother in the process of approaching the base 110, and the protruding portion 212 is clamped between the second connecting plate 133 and the support arm 120.

[0052] See Figure 1 and Figure 2In one embodiment, the photovoltaic color steel tile fixing device 100 further includes two sets of fasteners 122. The base 110 includes a first bottom plate 111 and a second bottom plate 112, which are spaced apart along the first direction OX. One support arm 120 is connected to an end of the first bottom plate 111 close to the second bottom plate 112, and the other support arm 120 is connected to an end of the second bottom plate 112 close to the first bottom plate 111. The first base plate 111 is provided with a first fastening hole 113, and the second base plate 112 is provided with a second fastening hole 114. Two sets of fasteners 122 are respectively and one by one passed through the multiple first fastening holes 113 and the multiple second fastening holes 114 to connect the base 110 to the position to be installed, so that the base 110 is formed by the first base plate 111 and the second base plate 112, and attached to the position to be installed, and is connected and fixed to the position to be installed by the first fastener 122 and the second fastener 122 respectively, thereby realizing the lightweight and miniaturization of the fixing device 100 of the photovoltaic color steel tile.

[0053] In one embodiment, the plurality of first fastening holes 113 are arranged along the second direction OY, and the plurality of second fastening holes 114 are arranged along the second direction OY. The plurality of first fastening holes 113 and the plurality of second fastening holes 114 correspond one-to-one along the first direction OX. The first direction OX, the second direction OY, and the thickness direction of the base 110 are perpendicular to each other. This makes the distribution of the fixing force during installation more uniform along the first direction OX and the second direction OY, thereby improving the securement of the photovoltaic color steel tile fixing device 100 to the installation location and the stability of the installation of the photovoltaic color steel tile 210.

[0054] In one embodiment, the base 110, support arm 120, elastic clamping portion 130, and support portion 121 are all formed by bending a plate, and the thickness of the plate is 1-2 mm, preferably, the thickness of the plate is 1.5 mm, to ensure the strength of the photovoltaic color steel tile fixing device 100. Specifically, the photovoltaic color steel tile fixing device 100 formed by bending a plate comprises, in order, a first bottom plate 111, one of the support arms 120, one of the second connecting plates 133, one of the bent portions 131, one of the first connecting plates 132, the support portion 121, another first connecting plate 132, another bent portion 131, another second connecting plate 133, another support arm 120, and the second bottom plate 112.

[0055] Specifically, the base 110, the support arm 120, the elastic clamping portion 130 and the support portion 121 are all made of alloy, such as iron-carbon alloy or aluminum alloy, preferably S250GD+AZM alloy, that is, hot-dip aluminum-zinc alloy / aluminum-zinc-magnesium alloy coated steel plate.

[0056] In one embodiment, the fixing device 100 for photovoltaic colored steel tiles further includes a coating, which is attached to the surfaces of the base 110 , the support arm 120 , the elastic clamping portion 130 , and the support portion 121 .

[0057] In one embodiment, the thickness of the coating is 15-25 μm. Preferably, the thickness of the coating is 20 μm to ensure the strength and corrosion resistance of the fixing device 100 of the photovoltaic color steel tile.

[0058] An embodiment of the present application further provides a photovoltaic color steel tile 210 structure, which includes: a photovoltaic color steel tile 210 and a plurality of photovoltaic color steel tile fixing devices 100.

[0059] The photovoltaic color steel tile 210 has a protruding structure 211 extending along the second direction OY. The protruding structure 211 includes two connecting members 213 , two protruding portions 212 , two protruding plates 214 and a top plate 215 .

[0060] The two ends of the top plate 215 are respectively connected to the protruding plate 214, the end of the protruding plate 214 facing away from the top plate 215 is connected to the protruding portion 212, and the end of the protruding portion 212 facing away from the protruding plate 214 is connected to the connecting member 213. The protruding portion 212 protrudes toward the side away from the base 110, and the protruding portion 212 is clamped between the clamping portion and the support arm 120. There is a gap between the support arm 120 and the protruding portion 212.

[0061] The inclination angle between the protruding plate 214 and the top plate matches the elastic clamping portion 130 .

[0062] During the actual installation process of the above-mentioned photovoltaic color steel tile fixing device 100, the base 110 is first installed at the installation position, and then the photovoltaic color steel tile 210 is covered on the photovoltaic color steel tile fixing device 100, and then the protruding structure 211 of the photovoltaic color steel tile 210 is moved toward the direction close to the base 110, so that the top plate 215 of the protruding structure 211 is attached to the side of the support part 121 away from the base 110. During the process of the protruding structure 211 of the photovoltaic color steel tile 210 moving toward the direction close to the base 110, the protruding parts 212 on both sides of the protruding structure 211 of the photovoltaic color steel tile 210 respectively squeeze the two elastic clips 130, so that the two elastic clips 130 are elastically deformed to be close to each other. Until the top plate 215 is attached to the side of the support portion 121 facing away from the base 110, the protrusion 212 moves to the lower side of the elastic clip 130, that is, the protrusion 212 moves between the elastic clip 130 and the base 110, and the elastic clip 130 is located between the two protruding plates 214, so that the elastic clip 130 can move away from each other and restore their original shape. At this time, the protrusion 212 is clamped between the clamping part and the support arm 120, and the protrusions 212 on both sides of the protruding structure 211 are respectively clamped by two elastic clamping parts 130 arranged along the first direction OX, and the inclination angle of the protruding plate 214 and the top plate is adapted to the elastic clamping part 130, thereby realizing the limitation of the photovoltaic color steel tile 210 along the first direction OX and the direction perpendicular to the base 110. At the same time, relative to the rigid fixing device, the elastic deformation of the elastic clamping part 130 makes the protrusion 212 of the photovoltaic color steel tile 210 as little as possible from the clamping part during the clamping process. At the same time, there is a gap between the support arm 120 and the protrusion 212, thereby preventing the surface of the photovoltaic color steel tile 210, especially the protrusion 212 that needs to be clamped with the elastic clamping part 130 from being damaged, thereby improving the service life of the photovoltaic color steel tile 210.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
