Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic system. Background Technology

[0002] Photovoltaic power generation is a device that converts solar energy into electrical energy based on the photoelectric effect. Building photovoltaics (BPV) can be integrated into buildings by installing photovoltaic devices on the exterior walls of buildings. As a key solution for the integration of buildings and energy, BPV technology has seen accelerated development in recent years driven by policy initiatives.

[0003] In related technologies, photovoltaic tiles may shift when exposed to strong winds, reducing structural strength and posing risks such as leaks or detachment. To stably fix the photovoltaic tiles to the substrate, structural adhesive can be used to bond them, replacing the traditional screw-drilling method used for corrugated steel tiles. This avoids the risk of water leakage caused by drilling and also improves wind resistance.

[0004] However, the use of structural adhesive for fixing makes it inconvenient to disassemble the photovoltaic tiles. Utility Model Content

[0005] Based on this, this application provides a photovoltaic system to solve the problem that photovoltaic tiles are inconvenient to disassemble in related technologies.

[0006] This application provides a photovoltaic system, which includes: a plurality of photovoltaic tiles arranged sequentially along a first direction, wherein two adjacent photovoltaic tiles include a first photovoltaic tile and a second photovoltaic tile, the first photovoltaic tile being located above the second photovoltaic tile in a second direction and the projections of the first photovoltaic tile and the second photovoltaic tile overlapping in the second direction, and the first direction and the second direction being perpendicular to each other; a support, wherein the first photovoltaic tile and the support are detachably connected; and a friction element connected to the second photovoltaic tile, wherein the friction element is mounted on the support to enable frictional engagement between the second photovoltaic tile and the support.

[0007] In one embodiment, the friction member has a plurality of elastic protrusions on the side facing the support, and the plurality of elastic protrusions are arranged sequentially along the first direction.

[0008] In one embodiment, the friction element includes an elastic element.

[0009] In one embodiment, the photovoltaic tile includes a laminate and a first frame, the first frame being connected to one side of the laminate along the first direction, and the friction member being connected to the first frame.

[0010] In one embodiment, the friction member includes a connecting portion and an abutting portion. The first frame is provided with a first mounting groove, which is arranged along the extending direction of the first frame. The connecting portion is located in the first mounting groove, and the abutting portion protrudes from the first mounting groove and rests on the support.

[0011] In one embodiment, the photovoltaic system further includes a waterproof strip, and the photovoltaic tile further includes a second frame connected to the other side of the laminate in the first direction. The waterproof strip is disposed on the side of the second frame of the first photovoltaic tile facing the second photovoltaic tile, and the waterproof strip abuts against the laminate of the second photovoltaic tile.

[0012] In one embodiment, the support is provided with a mounting cavity located below the first photovoltaic tile, and the second photovoltaic tile is inserted into the mounting cavity, with the friction element engaging with the cavity wall of the mounting cavity.

[0013] In one embodiment, the second photovoltaic tile is spaced apart from the cavity wall of the mounting cavity in a first direction; and / or, the second photovoltaic tile is spaced apart from the cavity wall of the mounting cavity in a second direction.

[0014] In one embodiment, one of the support and the first photovoltaic tile is provided with a hook, and the other of the support and the first photovoltaic tile is provided with an opening groove, and the hook is hooked into the opening groove.

[0015] In one embodiment, the photovoltaic system also includes connecting screws, through which the support is connected to the fixing body.

[0016] By applying the technical solution of this application, when dismantling the photovoltaic system, the connection between the first photovoltaic tile and the support is broken, thereby allowing the first photovoltaic tile to be separated from the support. Since the second photovoltaic tile is mounted on the support via friction components, it can be easily separated from the support, thus enabling the removal of both the first and second photovoltaic tiles. Furthermore, due to the frictional fit between the second photovoltaic tile and the support, the frictional force between the friction components and the support prevents the second photovoltaic tile from moving in the second direction, making the installation structure of the first and second photovoltaic tiles more stable and providing good fixation, preventing relative movement of the first and second photovoltaic tiles due to strong winds. Compared to related technologies that use structural adhesive to bond photovoltaic tiles to a substrate, the photovoltaic system of this application not only facilitates the fixation of photovoltaic tiles and improves wind resistance but also makes the removal of photovoltaic tiles easier.

[0027] See Figure 1 and Figure 2 , Figure 1 A cross-sectional view of a photovoltaic system provided in an embodiment of this application is shown. Figure 2 It shows Figure 1 A partial enlarged view at point A. One embodiment of this application provides a photovoltaic system including multiple photovoltaic tiles, a support 30, and a friction element 40. The photovoltaic tiles are arranged sequentially along a first direction X. Adjacent photovoltaic tiles include a first photovoltaic tile 10 and a second photovoltaic tile 20. The first photovoltaic tile 10 is positioned above the second photovoltaic tile 20 in a second direction Y. The projections of the first photovoltaic tile 10 and the second photovoltaic tile 20 in the second direction Y overlap, and the first direction X and the second direction Y are perpendicular. The first photovoltaic tile 10 and the support 30 are detachably connected. The friction element 40 is connected to the second photovoltaic tile 20, and the second photovoltaic tile 20 is supported on the support 30 via the friction element 40, allowing the second photovoltaic tile 20 to engage with the support 30 through friction.

[0028] By applying the technical solution of this application, when dismantling the photovoltaic system, the connection between the first photovoltaic tile 10 and the support 30 is broken, thereby separating the first photovoltaic tile 10 from the support 30. Since the second photovoltaic tile 20 is mounted on the support 30 via the friction member 40, the second photovoltaic tile 20 can be easily separated from the support 30, thus achieving the removal of the first photovoltaic tile 10 and the second photovoltaic tile 20. Furthermore, due to the frictional engagement between the second photovoltaic tile 20 and the support 30, the frictional force between the friction member 40 and the support 30 prevents the second photovoltaic tile 20 from moving in the second direction Y, thereby making the installation structure of the first photovoltaic tile 10 and the second photovoltaic tile 20 more stable, achieving a good fixing effect, and preventing relative movement of the first photovoltaic tile 10 and the second photovoltaic tile 20 due to strong winds. Compared with the method of using structural adhesive to bond photovoltaic tiles to the substrate in related technologies, the photovoltaic system of this application is not only beneficial for fixing photovoltaic tiles and improving wind resistance, but also facilitates the removal of photovoltaic tiles.

[0029] Generally, a photovoltaic system includes multiple photovoltaic tiles, which are arranged sequentially along a first direction X, with any two adjacent photovoltaic tiles overlapping each other in a second direction Y. The two adjacent photovoltaic tiles are the first photovoltaic tile 10 and the second photovoltaic tile 20 of this application; that is, the multiple photovoltaic tiles are arranged in a manner that alternates between the first photovoltaic tile 10 and the second photovoltaic tile 20.

[0030] It should be noted that the friction element 40 extends along a third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first direction X can be the length direction of the photovoltaic tile laminate, and the third direction Z can be the width direction of the photovoltaic tile laminate. Of course, the first direction X can also be the width direction of the photovoltaic tile laminate, and the third direction Z can be the length direction of the photovoltaic tile laminate. The second direction Y can be the thickness direction of the photovoltaic tile laminate.

[0031] The photovoltaic system of this application includes photovoltaic systems installed on rooftops or canopies.

[0032] In this application, the support 30 enables the fixation of the first photovoltaic tile 10 and the second photovoltaic tile 20. The first photovoltaic tile 10 is detachably connected to the support 30, allowing for easy disassembly after the connection is established. Furthermore, since the first photovoltaic tile 10 and the second photovoltaic tile 20 overlap in the second direction Y, and the first photovoltaic tile 10 is positioned above the second photovoltaic tile 20 in the second direction Y, the first photovoltaic tile 10 can limit the movement of the second photovoltaic tile 20, preventing it from moving above the first photovoltaic tile 10. Simultaneously, the friction member 40 allows the second photovoltaic tile 20 to be placed on the support 30, thus providing support. The frictional engagement between the friction member 40 and the support 30 prevents relative displacement between them. Therefore, the friction member 40 and the support 30 achieve stable fixation between adjacent photovoltaic tiles.

[0033] In some embodiments, in the first direction X, the first end of the first photovoltaic tile 10 is connected to the second end of the second photovoltaic tile 20 via a support 30. Furthermore, the structure of each photovoltaic tile in this application is identical; that is, the structures of the first photovoltaic tile 10 and the second photovoltaic tile 20 are identical. Also, the first end of the first photovoltaic tile 10 and the first end of the second photovoltaic tile 20 have the same structure, and the second end of the first photovoltaic tile 10 and the second end of the second photovoltaic tile 20 have the same structure. Therefore, during the removal of the photovoltaic system, as long as the connection structure between the first end of the first photovoltaic tile 10 and the support 30 is removed, since the second end of the first photovoltaic tile 10 only engages with the support 30 through friction elements 40, the first photovoltaic tile 10 can be removed simply by separating the second end of the first photovoltaic tile 10 from the support 30. The removal process for the second photovoltaic tile 20 and the remaining photovoltaic tiles is the same as described above, thereby enabling easy removal of the photovoltaic system.

[0034] In some embodiments, the friction element 40 includes an elastic element, such as an elastic rubber strip. Elastic rubber strips have the advantages of being readily available, low in cost, and easy to install.

[0035] The elastic strip is made of polymer materials, such as natural rubber, synthetic rubber, or thermosetting elastomers, possessing high elasticity and resilience. It can withstand significant deformation and quickly return to its original shape after the external force is removed. Therefore, after installation, it can elastically deform under its own weight, generating significant friction between the second photovoltaic tile 20 and the support 30. During disassembly, first disconnect the first end of the second photovoltaic tile 20 from the support 30. The operator then manipulates the second photovoltaic tile 20, slightly lifting the second end. The elastic strip rebounds due to its own resilience, reducing the friction between the second photovoltaic tile 20 and the support 30, allowing for easy removal of the second photovoltaic tile 20.

[0036] It should be noted that this application does not limit the number of elastic adhesive strips. In some embodiments, only one elastic adhesive strip may be provided between the second photovoltaic tile 20 and the support 30. In some embodiments, multiple elastic adhesive strips may also be provided between the second photovoltaic tile 20 and the support 30. An appropriate number of elastic adhesive strips can be selected according to the model of the photovoltaic tile.

[0037] Combination Figure 1 and Figure 2 As shown, the friction element 40 has multiple elastic protrusions 41 on the side facing the support 30, and these protrusions 41 are arranged sequentially along the first direction X. With this design, after the photovoltaic system is assembled, the weight of the second photovoltaic tile 20 causes the multiple elastic protrusions 41 to deform, thereby increasing the contact area between the elastic strip and the support 30, resulting in greater friction between the second photovoltaic tile 20 and the support 30. During removal, the elastic strip rebounds due to its own elasticity and contacts the support 30 through the elastic protrusions 41, thus reducing the contact area between the elastic strip and the support 30, thereby reducing the friction between the second photovoltaic tile 20 and the support 30, facilitating the removal of the second photovoltaic tile 20.

[0038] In some embodiments, each elastic protrusion 41 extends along a third direction Z.

[0039] When there are multiple elastic rubber strips, elastic protrusions 41 can be provided on each elastic rubber strip.

[0040] Combination Figure 1 As shown, the second photovoltaic tile 20 includes a laminate 21 and a first frame 22. The first frame 22 is connected to one side of the laminate 21 along the first direction X, and the friction member 40 is connected to the first frame 22. With this design, by directly setting the friction member 40 to the first frame 22 of the photovoltaic tile, no additional components are needed, reducing manufacturing costs and simplifying the installation structure.

[0041] Combination Figure 2 As shown, the friction element 40 includes a connecting portion 42 and an abutting portion 43. A first mounting groove 23 is provided on the first frame 22, extending along the first frame 22. The connecting portion 42 is located within the first mounting groove 23, and the abutting portion 43 protrudes from the first mounting groove 23 and rests on the support 30. With this design, the first mounting groove 23 can limit and fix the friction element 40, preventing relative movement between the friction element 40 and the second photovoltaic tile 20, thus enabling the friction element 40 to provide appropriate friction for both the second photovoltaic tile 20 and the support 30.

[0042] The first mounting groove 23 has a T-shaped structure, and the friction component 40 is deformed into an H-shaped structure after being installed into the first mounting groove 23.

[0043] In some embodiments, in order to provide a good fixing effect for the friction member 40, the first mounting groove 23 extends along the third direction Z, and the friction member 40 is limited and fixed by the first mounting groove 23 throughout the entire length direction of the friction member 40.

[0044] Combination Figure 1 As shown, the support 30 is provided with a mounting cavity 31, which is located below the first photovoltaic tile 10. The second photovoltaic tile 20 is inserted into the mounting cavity 31, and the friction member 40 is in frictional engagement with the cavity wall of the mounting cavity 31. By inserting the second photovoltaic tile 20 into the mounting cavity 31, the cavity wall of the mounting cavity 31 can be used to support and limit the photovoltaic tile, further preventing the photovoltaic tile from moving within the mounting cavity 31.

[0045] In some embodiments, the second photovoltaic tile 20 has a gap between itself and the cavity wall of the mounting cavity 31 in the first direction X. With this design, when the second photovoltaic tile 20 moves due to strong winds, the gap between it and the mounting cavity 31 in the first direction X provides a buffering effect, thereby preventing the second photovoltaic tile 20 from directly contacting the support 30 and avoiding damage from impact.

[0046] In some embodiments, the second photovoltaic tile 20 has a gap between itself and the cavity wall of the mounting cavity 31 in the second direction Y. With this design, when the second photovoltaic tile 20 moves due to strong winds, the gap between it and the mounting cavity 31 in the second direction Y provides a buffering effect, thereby preventing the second photovoltaic tile 20 from directly contacting the support 30 and avoiding damage from impact.

[0047] Combination Figure 1As shown, one of the support 30 and the first photovoltaic tile 10 is provided with a hook 11, and the other of the support 30 and the first photovoltaic tile 10 is provided with an opening groove 32, in which the hook 11 is hooked. With the above design, the hook 11 and the opening groove 32 are engaged to facilitate both the installation and disassembly of the photovoltaic tile.

[0048] Specifically, during installation, the first photovoltaic tile 10 is moved along the third direction Z so that the hook 11 is hooked into the opening groove 32, thus enabling the support 30 to support the photovoltaic tile. During disassembly, the first photovoltaic tile 10 is moved in the opposite direction Z so that the hook 11 is disengaged from the opening groove 32, thus separating the first photovoltaic tile 10 from the support 30.

[0049] The opening groove 32 has an opening not only in the first direction X, but also in the third direction Z. During photovoltaic tile installation, by moving the first photovoltaic tile 10 along the third direction Z, the hook 11 can enter the opening groove 32 through the opening in the third direction Z. Then, through the opening in the first direction X, the first photovoltaic tile 10 can continue to move in the third direction Z to be installed in place.

[0050] In some embodiments, the hook 11 is bonded to the lower surface of the laminate 21 of the first photovoltaic tile 10. Using an adhesive connection to attach the hook 11 to the first photovoltaic tile 10 offers advantages such as simple structure and ease of operation.

[0051] Of course, the adhesive method of hook 11 is only one way to connect hook 11 to the first photovoltaic tile 10. Other methods can also be used to install hook 11 to the first photovoltaic tile 10, such as screw connection.

[0052] In some embodiments, the second frame 24 of the first photovoltaic tile 10 is provided with a positioning groove 241, and the side of the hook 11 away from the support 30 is provided with a positioning protrusion 111. The positioning protrusion 111 is inserted into the positioning groove 241, thereby enabling the hook 11 to be positioned according to the position of the second frame 24 of the photovoltaic tile, and determining the relative position of the hook 11 so that after the hook 11 is installed, it can form a hook-and-hook engagement structure with the support 30.

[0053] Combination Figure 1As shown, the photovoltaic system also includes a waterproof strip 50, and the photovoltaic tile also includes a second frame 24. The second frame 24 is connected to the other side of the laminate 21 along the first direction X. The waterproof strip 50 is disposed on the side of the second frame 24 of the first photovoltaic tile 10 facing the second photovoltaic tile 20, and the waterproof strip 50 abuts against the laminate 21 of the second photovoltaic tile 20. With the above design, the waterproof strip 50 can fill the gap between the first photovoltaic tile 10 and the second photovoltaic tile 20 in the second direction Y, thereby preventing rainwater or debris from entering between the first photovoltaic tile 10 and the second photovoltaic tile 20 through the gap, thus providing protection for the photovoltaic tile.

[0054] After the elastic sealing strip is installed, it is located on one side of the second photovoltaic tile 20. This results in a certain distance between the waterproof sealing strip 50 and the elastic sealing strip in the first direction X.

[0055] By contacting the waterproof strip 50 with the upper surface of the second photovoltaic tile 20, even if there is a gap between the end of the second photovoltaic tile 20 and the mounting cavity 31 in the first direction X, the pressure provided by the waterproof strip 50, as well as the supporting force and friction provided by the elastic strip, can tightly limit the end of the second photovoltaic tile 20 in the mounting cavity 31, so that the second photovoltaic tile 20 will not move.

[0056] In some embodiments, in order to further enhance the waterproof and limiting effects, the size of the waterproof strip 50 in the second direction Y can be set to be larger than the interval between the first photovoltaic tile 10 and the second photovoltaic tile 20, so that after the waterproof strip 50 is installed, it can produce a certain elastic deformation, and can even be squeezed to extend towards the first direction X, thereby forming an interference fit effect and tightly adhering to the upper surface of the second photovoltaic tile 20.

[0057] Combination Figure 1 As shown, the photovoltaic system also includes connecting screws 60, and the support 30 is connected to the fixing body 70 via the connecting screws 60. Connecting the support 30 to the fixing body 70 via the connecting screws 60 has the advantage of facilitating disassembly.

[0058] In some embodiments, the fixing body 70 refers to the support structure used to support the photovoltaic system, which may be a foundation, purlin, or bracket, etc.

[0059] In some embodiments, the support 30 includes a connecting plate, a U-shaped plate, and an L-shaped plate. The connecting plate is connected to the lower part of the U-shaped plate in the second direction Y, and the L-shaped plate is connected to the upper part of the U-shaped plate in the second direction Y. A connecting screw 60 passes through the connecting plate and connects to the fixing body 70, thereby connecting the fixing body 70 and the connecting plate. A mounting cavity 31 is provided in the U-shaped plate. An opening slot 32 is provided in the L-shaped plate. The openings of the mounting cavity 31 and the opening slot 32 are oriented in different directions.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
