Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic tiles, in particular to an integrated photovoltaic tile. Background Art

[0002] Integrated photovoltaic tiles are an integrated technology for photovoltaic building integration. They integrate photovoltaic panels with the roof tiles of the building and lay them directly on the roof. This saves the connection brackets between photovoltaic panels and traditional roof tiles, and facilitates the installation and maintenance of photovoltaic panels and roof tiles.

[0003] Usually, integrated photovoltaic tiles are directly bonded and fixed to the photovoltaic panels and tiles with adhesives. However, adhesives are easily degraded by temperature, especially when applied to building roofs. When the climate is hot, the adhesives will degrade quickly, which can easily cause the photovoltaic panels to fall off the tiles, reducing the service life and safety of the product. In addition, since the photovoltaic panels and tiles are bonded together, if the photovoltaic panels need to be repaired or replaced, the entire integrated photovoltaic tile needs to be removed from the roof, which makes the operation very inconvenient. Utility Model Content

[0004] The utility model aims to provide an integrated photovoltaic tile to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] First, the utility model provides an integrated photovoltaic tile, which includes a tile base, the tile base is a square structure, a groove is provided in the middle, a plurality of support bars are convexly provided on the bottom surface of the groove, a stop portion is provided on the lower frame of the tile base, and the stop portion is provided with a stop groove facing the upper frame; a photovoltaic panel, the photovoltaic panel is embedded in the groove and supported by the support bars, the lower end of the photovoltaic panel is inserted in the stop groove, and a gap is provided between the upper end of the photovoltaic panel and the upper wall of the groove; a cover plate, the cover plate is connected to the upper outer surface of the tile base by fasteners, and the upper end of the photovoltaic panel is pressed against the support bar.

[0007] The beneficial effect of the utility model is that the lower end of the photovoltaic panel of this embodiment is inserted into the lower frame, and then is pressed and fixed by a cover plate arranged on the upper end of the photovoltaic panel, which can avoid the use of adhesive bonding, and at the same time a gap is arranged to provide an operating space for disassembling the photovoltaic panel. In this way, the photovoltaic panel can be firmly fixed on the tile base and is not easy to fall off, which not only enhances the service life and safety of the product, but also improves the convenience of repairing and replacing the photovoltaic panel.

[0008] As a further improvement of the above technical solution, a plug-in block is provided on the bottom surface of the cover plate, the plug-in block is inserted in the gap, the plug-in block is penetrated by a mounting hole, and a fastener passes through the mounting hole to connect with the tile base. On the one hand, the plug-in block can fill the gap between the photovoltaic panel and the upper frame to ensure that the photovoltaic panel does not shake; on the other hand, it realizes the fixed connection between the photovoltaic panel and the tile base, and the structure is compact and ingenious.

[0009] As a further improvement of the above technical solution, the plug-in block extends from the edge of the cover plate toward the gap. That is, the cover plate is set to an L-shaped structure, which can reduce the width of the cover plate. When two adjacent integrated photovoltaic tiles are overlapped, the lower frame of the first photovoltaic tile located above can avoid the cover plate for overlap. Then, when the photovoltaic panel needs to be disassembled, the photovoltaic panel can be disassembled without disassembling the tile matrix, which is easy to operate and can save work time and manpower.

[0010] As a further improvement of the above technical solution, a sealing strip is provided between the mating surfaces of the cover plate and the upper frame, so as to reduce the infiltration of rainwater.

[0011] As a further improvement of the above technical solution, the support bar extends longitudinally in the groove. The longitudinal arrangement of the support bar is more conducive to air circulation, so that the heat of the photovoltaic panel can be better dissipated to the outside.

[0012] As a further improvement of the above technical solution, the support bar includes at least two first support bars, the upper ends of the first support bars are connected to the upper wall of the groove, and the two first support bars separate a receiving space in the groove for receiving the photovoltaic panel back junction box. The first support bars protruding on both sides of the junction box can block rainwater from flowing to the junction box, protecting the junction box and the wiring harness connected to the junction box from being invaded by rainwater.

[0013] As a further improvement of the above technical solution, the upper end of the first support bar is provided with a connecting hole corresponding to the fastener.

[0014] As a further improvement of the above technical solution, the upper frame is provided with a wire hole at a position corresponding to the accommodation space. The wire hole is arranged on the upper frame to better protect the wire harness from being invaded by rainwater and to prevent rainwater from seeping into the roof from the bottom surface.

[0015] As a further improvement of the above technical solution, the support bar further includes second support bars respectively arranged on the left and right sides of the groove. The second support bars are used to support the left and right sides of the photovoltaic panel so that the photovoltaic panel can be more stably embedded in the groove of the tile base.

[0016] As a further improvement of the above technical solution, the lower frame is provided with an opening connected to the entire lower channel of the groove, and the lower end of the support bar is connected to the lower frame. While ensuring good heat dissipation of the photovoltaic panel, the strength of the lower frame can be increased, ensuring that the lower frame has sufficient strength to abut the lower end of the photovoltaic tile.

[0031] Embodiment 1:

[0032] Reference Figure 1 to Figure 6 The integrated photovoltaic tile of embodiment 1 of the present invention is described, which includes a tile base 100, a photovoltaic panel 200, and a cover plate 300. Figure 3 As shown, a groove is provided in the middle of the tile substrate 100, and the upper frame 105, the lower frame 106, the left frame, and the right frame arranged around the groove make the tile substrate 100 form a square structure, the depth of the groove is less than the thickness of the tile substrate 100, and the width of the groove is consistent with the width of the photovoltaic panel 200. Figure 1 and Figure 2 As shown, the photovoltaic panel 200 is embedded in the groove, the lower end of the photovoltaic panel 200 is fixed by the lower frame 106, and the upper end of the photovoltaic panel 200 is fixed by the cover plate 300. Figure 2 The dotted line in FIG. 2 is the boundary of the photovoltaic panel 200 .

[0033] Specifically, two first support bars 102 for supporting the photovoltaic panel 200 are convexly arranged on the bottom surface of the groove, and the first support bars 102 are arranged along the longitudinal direction of the tile base 100, and the upper ends of the first support bars 102 are connected to the upper wall surface of the groove, and the lower ends of the first support bars 102 are connected to the lower frame 106. A connection hole is also arranged at the upper end of the first support bar 102.

[0034] It should be noted that the longitudinal direction of the present embodiment refers to the direction extending from the upper frame 105 to the lower frame 106 , and the transverse direction refers to the direction extending from the left frame to the right frame.

[0035] When the photovoltaic panel 200 is placed on the first support bar 102, a certain distance is maintained between the lower surface of the photovoltaic panel 200 and the bottom surface of the groove, and the space formed by the distance can allow the heat of the photovoltaic panel 200 to dissipate outward. The two longitudinally arranged first support bars 102 also separate the groove into a receiving space 109. When the photovoltaic panel 200 is placed on the first support bar 102, the junction box on the back of the photovoltaic panel 200 is located in the receiving space 109. The first support bars 102 arranged on the left and right sides of the junction box prevent rainwater from easily flowing into the receiving space 109, thereby protecting the junction box and the wiring harness connected to the junction box from being invaded by rainwater.

[0036] Furthermore, the upper frame 105 is provided with a wire hole 110 at a position corresponding to the accommodating space 109, and the wiring harness connected to the junction box passes through the wire hole 110. Compared with the wire hole arranged on the bottom surface of the groove, the wire hole 110 arranged on the upper frame 105 can better protect the wire harness from being invaded by rainwater, and can also prevent rainwater from seeping into the roof from the bottom surface.

[0037] Furthermore, the left and right sides of the groove are respectively provided with second support bars 108, which are also arranged along the longitudinal direction. The second support bars 108 are used to support the left and right sides of the photovoltaic panel, so that the photovoltaic panel 200 can be more stably embedded in the groove.

[0038] In some other embodiments, the support bars may not be arranged longitudinally, for example, some support bars may be arranged obliquely. However, it is understandable that the longitudinal arrangement is more conducive to air circulation, so that the heat of the photovoltaic panel 200 can be better dissipated to the outside.

[0039] In some other embodiments, according to the size of the photovoltaic panel 200, more support bars may be added to other areas of the groove outside the accommodating space 109 to support the photovoltaic panel.

[0040] Reference Figure 3-Figure 5 As shown, the upper surface of the lower frame 106 of the tile base 100 is higher than the upper surfaces of the first support bar 102 and the second support bar 108, and the raised portion is formed into a stopper 103 with a boss structure, and the boss structure is configured to stop the lower end of the photovoltaic panel 200. The stopper 103 begins to have a stopper groove 104 facing the upper frame 105. When the photovoltaic panel 200 is placed on the first support bar 102, the lower end of the photovoltaic panel 200 is inserted into the stopper groove 104. It can be understood that the stopper 103 can be a horizontal bar structure extending over the entire width of the tile base 100, or a horizontal bar structure extending over a partial width of the tile base 100, as long as it can stop the photovoltaic panel.

[0041] Furthermore, the lower frame 106 of the tile substrate 100 is provided with a transversely extending opening, which is connected to the entire lower channel of the groove. Figure 3 As shown, the two first support bars 102 divide the groove into three channels, and the opening of the lower frame 106 is connected to the entire lower channel of the groove, which means that the opening is connected to all three channels. This arrangement is to allow the heat accumulated in the groove to be dissipated to the outside. In this embodiment, preferably, the width of the opening is set to be the same as the width of the groove, so as not to cause local overheating.

[0042] Since the lower end of the first support bar 102 is connected to the lower frame 106, the lower end of the first support bar 102 divides the opening of the lower frame 106 into three small openings. This does not affect the heat dissipation of the photovoltaic panel, but can increase the strength of the lower frame 106 and ensure that the lower frame 106 has sufficient strength to abut the lower end of the photovoltaic tile 200.

[0043] Reference Figure 1 As shown, since the lower end of the photovoltaic panel 200 is inserted into the stop groove 104, in order to facilitate the photovoltaic panel 200 to be removed from the groove during disassembly, the longitudinal dimension of the photovoltaic panel 200 is set so that when the lower end thereof is inserted into the stop groove 104, a gap 107 is provided between the upper end thereof and the upper wall surface of the groove. The gap 107 provides an operating space so that a hand or a tool can be inserted into the gap 107 to pry the photovoltaic panel 200 out of the groove.

[0044] The cover plate 300 is a strip-shaped structure, and the cover plate 300 presses the upper end of the photovoltaic panel 200 against the support strip in the groove. Figure 6 As shown, its cross section is L-shaped, one side of which is covered on the photovoltaic panel 200, and the other side is inserted into the gap 107 as a plug-in block 302. The cover plate 300 is provided with a mounting hole 301 in the transverse direction, the mounting hole 301 passes through the plug-in block 302, and the fastener passes through the mounting hole 301 to be connected to the connection hole on the first support bar 102.

[0045] Furthermore, a sealing strip is provided between the mating surface of the cover plate 300 and the upper frame to improve the sealing performance of the two and reduce the infiltration of rainwater. For example, a sealing strip can be embedded on the upper wall surface of the groove, or the sealing strip can be pasted on the side of the plug-in block 302.

[0046] The lower end of the photovoltaic panel 200 of the present embodiment is inserted into the lower frame 106, and then is pressed and fixed by the cover plate 300 arranged on the upper end of the photovoltaic panel 200, which can avoid the use of adhesive bonding. At the same time, a gap 107 is provided to provide an operating space for disassembling the photovoltaic panel 200. In this way, the photovoltaic panel can be firmly fixed on the tile base and is not easy to fall off, which not only enhances the service life and safety of the product, but also improves the convenience of repairing and replacing the photovoltaic panel.

[0047] Embodiment 2:

[0048] The difference between the second embodiment and the first embodiment is that the cross section of the cover plate 300 can also be set to Figure 7 The T-shape shown in , or set to Figure 8 As shown in the straight line, the lower cover plate 303 on one side of the two cover plates is covered on the photovoltaic tile 200, and the upper cover plate 304 on the other side is covered on the upper frame 105 of the tile substrate 100. The installation hole 301 is set through the upper cover plate 304, that is, the cover plate 300 is fixedly connected to the upper frame 105 through the upper cover plate 304; for the cover plate with a straight line structure, a limiter can be separately set in the gap 107 to fill the gap 107. Of course, the limiter can also be not set. When the pressing force of the cover plate is sufficient, the photovoltaic panel is not easy to shift. When the installation hole 301 is set on the upper cover plate 304, the connection hole of the tile substrate 100 is correspondingly set on the upper frame 105 instead of the first support bar 102.

[0049] However, compared with the T-shaped structure and the I-shaped structure of the cover plate in Example 2, the plug-in block 302 of Example 1 can fill the gap 107 on the one hand, so that the photovoltaic panel 200 will not shake in the groove; on the other hand, by connecting the plug-in block 302 to the tile base 100, there is no need to set up the upper cover plate 304 to achieve the connection. Therefore, the width dimension of the cover plate 300 can be reduced, that is, the dimension of the cover plate 300 along the longitudinal direction of the integrated photovoltaic tile can be reduced.

[0050] Reducing the width of the cover is beneficial for the integrated photovoltaic tile. When the integrated photovoltaic tile is installed on the roof, an assembly scenario is referred to as follows: Fig. 9As shown, in order to prevent rainwater from seeping in through the gap between two adjacent integrated photovoltaic tiles, the two adjacent integrated photovoltaic tiles in the longitudinal direction are overlapped up and down to eliminate the gap, and the lower frame of the first photovoltaic tile 400 located above the roof is pressed on the upper frame of the second photovoltaic tile 500 located below, so that rainwater flows continuously on the spliced ​​integrated photovoltaic tiles and will not seep into the roof. Therefore, in such an assembly scenario, since the cover plate 300 of Example 1 is not provided with an upper cover plate 304, the lower frame of the first photovoltaic tile 400 can avoid the cover plate 300 when pressing the second photovoltaic tile 500. When the photovoltaic panel 200 is damaged and needs to be repaired or replaced, the photovoltaic panel 200 can be taken out by simply removing the cover plate 300, which greatly improves the convenience of maintenance. It is understandable that if a T-shaped structure and a straight-line structure cover are used, the first photovoltaic tile 400 and the second photovoltaic tile 500 are in the same assembly position, and the size of the photovoltaic panel 200 remains unchanged, the lower frame of the first photovoltaic tile 400 will cover the cover 300. At this time, if the photovoltaic panel 200 is to be disassembled, the photovoltaic tiles around the entire periphery need to be loosened, and the convenience and efficiency of disassembly will be greatly reduced. If the size of the photovoltaic panel is reduced so that the cover 300 can avoid the pressure of the lower frame in order to be able to disassemble the target photovoltaic panel separately, the power generation will be affected due to the reduction in the size of the photovoltaic panel.

[0051] The preferred implementation modes of the present invention are specifically described above, but the novel creation of the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
