Description

Technical Field

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

[0002] As photovoltaic power generation technology matures and manufacturing costs decrease, people are beginning to consider how to integrate photovoltaic power generation with building roofs, combining roofs that originally only served as sunshades and windbreaks with solar cells, making full use of roof resources, and turning roofs into photovoltaic power stations to provide residents with their own electricity.

[0003] In existing technologies, photovoltaic (PV) power stations are formed by installing PV tiles on the roof and mounting battery modules on the tiles. However, current PV tiles have poor waterproofing performance, requiring additional waterproofing treatment on the roof substrate, which significantly increases the overall cost of using a rooftop PV power station. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this application is to provide a photovoltaic tile system to at least solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a photovoltaic tile system, including a tile hanger and a plurality of photovoltaic tiles. The first end of the photovoltaic tile is arched to form a first arched portion, and the second end of the photovoltaic tile is arched to form a second arched portion. Along the length direction of the tile hanger, the plurality of photovoltaic tiles are sequentially fixed side by side to the tile hanger. The first arched portion of the photovoltaic tile is stacked on the second arched portion of the adjacent photovoltaic tile. The edge of the first arched portion facing away from the second arched portion is bent and extends to form a first abutting portion, which is used to abut against the upper surface of the adjacent photovoltaic tile.

[0006] Optionally, the photovoltaic tile includes a main body and a first arched portion and a second arched portion disposed opposite to each other on both sides of the main body. The surface of the first arched portion arched on one side is the first upper surface, and the surface of the second arched portion arched on one side is the second upper surface. The first upper surface, the second upper surface, the connection between the first upper surface and the main body, and the connection between the second upper surface and the main body are all arc-shaped curved surfaces.

[0007] Optionally, the number of the tile strips is at least two, and the tile strips are arranged alternately from high to low; along the arrangement direction of the tile strips, the photovoltaic tile has a third end and a fourth end arranged opposite to each other, and the third end of the photovoltaic tile is stacked on top of the fourth end of the adjacent photovoltaic tile.

[0008] Optionally, the edge of the third end of the photovoltaic tile is bent and extends to form a second abutment portion, which is used to abut against the upper surface of the adjacent photovoltaic tile.

[0009] Optionally, a drainage groove is formed between the first arch and the second arch, and the drainage grooves of adjacent photovoltaic tiles are connected one-to-one along the arrangement direction of the tile strips.

[0010] Optionally, the photovoltaic tile further includes a windproof fixing part, one end of which is connected to the photovoltaic tile, and the other end of which extends below the fourth end of the adjacent photovoltaic tile along the arrangement direction of the tile strips; the windproof fixing part and the third end of the photovoltaic tile together clamp the fourth end of the adjacent photovoltaic tile.

[0011] Optionally, the fourth end of the photovoltaic tile is provided with an anti-backflow rib, which extends from the first end of the photovoltaic tile to the second end of the photovoltaic tile.

[0012] Optionally, along the arrangement direction of the roofing strips, the edge of the third end of the photovoltaic tile passes over the anti-backflow rib of the adjacent photovoltaic tile and abuts against the upper surface of the adjacent photovoltaic tile.

[0013] Optionally, the batten includes several segments and several connectors. Each segment is provided with a connecting groove, which extends through the segment along the length of the batten. Each connector includes a limiting part, a clamping part, and a locking bolt. Along the length of the batten, the two ends of the limiting part are respectively inserted into the connecting grooves of two adjacent segments. Along the length of the batten perpendicular to the length of the batten, the locking bolt passes through the sidewall of the clamping part and the connecting groove and is screwed to the limiting part. The clamping part and the limiting part together clamp and fix the batten to the sidewall of the connecting groove.

[0014] Optionally, the tile strip is provided with a wire groove, which extends along the length of the tile strip.

[0015] The beneficial effects of this application's embodiments are as follows: Unlike the prior art, in the photovoltaic tile system of this application, along the length direction of the tile strip, the first arched portion of the photovoltaic tile overlaps the second arched portion of an adjacent photovoltaic tile, and the first abutting portion abuts against the upper surface of the adjacent photovoltaic tile. The first arched portion and the second arched portion cooperate with each other to prevent liquid from flowing from one side of the photovoltaic tile to the other through the gap at the connection between two adjacent photovoltaic tiles.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] In the description of this specification, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see Figure 1 , Figure 2 and Figure 4 The photovoltaic tile system 1000 includes a tile mounting strip 1 and several photovoltaic tiles 2. The tile mounting strip 1 is used to fix the photovoltaic tiles 2. The first end of the photovoltaic tile 2 is arched to form a first arched portion 21, and the second end of the photovoltaic tile 2 is arched to form a second arched portion 22. Along the length direction a of the tile mounting strip 1, several photovoltaic tiles 2 are sequentially fixed side-by-side to the tile mounting strip 1. Figure 4As shown, the first arched portion 21 of the photovoltaic tile 2 is stacked on the second arched portion 22 of the adjacent photovoltaic tile 2. When the photovoltaic tile system 1000 is installed, the tile strip 1 is fixed to the mounting surface of the area where the photovoltaic tile 2 needs to be laid, the photovoltaic tile 2 is fixed to the tile strip 1, and the photovoltaic tile 2 covers the mounting surface. The arched side surface of the first arched portion 21 and the second arched portion 22 is the upper surface S of the photovoltaic tile 2, and the recessed side surface of the first arched portion 21 and the second arched portion 22 is the lower surface of the photovoltaic tile 2. The lower surface of the photovoltaic tile 2 faces the mounting surface of the tile strip 1, and the upper surface S of the photovoltaic tile 2 faces away from the mounting surface of the tile strip 1. The first arch 21, stacked above the second arch 22, covers the second arch 22. The second arch 22, located below, blocks liquid flow along the length of the tile strip 1. Thus, along the length a of the tile strip 1, the first arch 21 and the second arch 22 cooperate to prevent liquid from flowing from one side of the photovoltaic tile 2 to the other through the gap at the connection between two adjacent photovoltaic tiles 2. Furthermore, the first arch 21 extends a first abutting portion 211 after its edge is bent away from the second arch 22. The first abutting portion 211 abuts against the upper surface S of the adjacent photovoltaic tile 2. This makes the first arch 21 and the second arch 22 of the adjacent photovoltaic tile 2 fit together more tightly, improving the waterproof performance at the connection between the first arch 21 and the second arch 22 of the adjacent photovoltaic tile 2.

[0030] In this way, the photovoltaic tile system 1000 of this application has a waterproof function at the connection between the photovoltaic tiles 2 arranged side by side along the length direction a of the tile strip 1. Therefore, the installation surface covered by the photovoltaic tile system 1000 does not need to be waterproofed, which reduces the overall cost of using the photovoltaic tile system 1000.

[0031] For the photovoltaic tile 2 mentioned above, please refer to... Figure 2 and Figure 4Specifically, in this embodiment, the photovoltaic tile 2 includes a main body 23, a first arched portion 21, and a second arched portion 22. The first arched portion 21 and the second arched portion 22 are disposed at opposite ends of the main body 23. One end of the first arched portion 21 is connected to the first end of the main body 23, and one end of the second arched portion 22 is connected to the second end of the main body 23. The arched side surface of the first arched portion 21 is the first upper surface S1, and the arched side surface of the second arched portion 22 is the second upper surface S2. Along the direction from the upper surface S of the photovoltaic tile 2 to the lower surface of the photovoltaic tile 2, the first abutting portion 211 is formed by bending and extending one end edge of the first arched portion 21 away from the second arched portion 22. The first abutting portion 211 abuts against the second upper surface S2 of the second arched portion 22 of the adjacent photovoltaic tile 2. The first upper surface S1 and the second upper surface S2, the connection between the first upper surface S1 and the main body 23, and the connection between the second upper surface S2 and the main body 23 are all arc-shaped curved surfaces. The first upper surface S1 of the first arched portion 21, the second upper surface S2 of the second arched portion 22, and the upper surface of the main body 23 together form a drainage channel T, which can serve as a drainage channel. Compared with other embodiments, where the first upper surface S1 and the second upper surface S2 are configured as planes, and the connection between the first upper surface S1 and the main body 23 and the connection between the second upper surface S2 and the main body 23 are configured as angled surfaces, the drainage channel T formed by the first upper surface S1, the second upper surface S2, and the main body 23 in this application is more conducive to water flow. More specifically, the first arched portion 21 and the second arched portion 22 are both arc-shaped plates. The first arched portion 21 is formed by bending and extending the first end of the main body 23, and the second arched portion 22 is formed by bending and extending the second end of the main body 23.

[0032] It should be understood that this application does not specifically limit the shape of the first arched portion 21 and the second arched portion 22. For example, in other embodiments of this application, the first arched portion 21 and the second arched portion 22 may also be in the shape of a cross section that is generally triangular, trapezoidal, etc., which will not be detailed here.

[0033] Please see Figure 1 and Figure 5In some embodiments, the number of tile strips 1 is at least two, and the tile strips 1 are arranged alternately from high to low, for use on roofs and other equipment or facilities with an inclined mounting surface Z. Along the arrangement direction b of the tile strips 1, the photovoltaic tile 2 has a third end and a fourth end arranged opposite each other. The third end of the photovoltaic tile 2 is stacked above the fourth end of an adjacent photovoltaic tile 2. Thus, under gravity, the liquid flows over the upper surface of the third end of the photovoltaic tile 2 and then flows to the upper surface of the lower upper surface of the fourth end of the adjacent photovoltaic tile 2. Gravity prevents the liquid from flowing through the gap between the third end and the adjacent fourth end of the photovoltaic tile 2 to the side facing the lower surface of the photovoltaic tile 2. Along the arrangement direction b of the tile strips 1, the drainage channels T of adjacent photovoltaic tiles 2 are connected one-to-one, allowing the liquid to flow sequentially from high to low along the arrangement direction of the tile strips 1 through the drainage channels T of adjacent photovoltaic tiles 2.

[0034] For further details, please refer to Figure 2 In some embodiments, a second abutment portion 24 extends from the edge of the third end of the photovoltaic tile 2 after being bent, and the second abutment portion 24 is used to abut against the upper surface S of an adjacent photovoltaic tile 2. Specifically, in the direction from the upper surface S of the photovoltaic tile 2 to the lower surface of the photovoltaic tile 2, the second abutment portion 24 is formed by extending from the third end of the photovoltaic tile 2 after being bent. The second abutment portion 24 includes a first portion 241 extending from the edge of the first arched portion 21 after being bent, a second portion 242 extending from the edge of the body 23 after being bent, and a third portion 243 extending from the edge of the second arched portion 22 after being bent. The first portion 241 abuts against the upper surface of the first arched portion 21 of the adjacent photovoltaic tile 2, the second portion 242 abuts against the upper surface of the body 23 of the adjacent photovoltaic tile 2, and the third portion 243 abuts against the upper surface of the second arched portion 22 of the adjacent photovoltaic tile 2. This allows the third end of photovoltaic tile 2 to fit more tightly with the fourth end of the adjacent photovoltaic tile 2, improving the waterproof performance at the connection between the third end of photovoltaic tile 2 and the fourth end of the adjacent photovoltaic tile 2.

[0035] For the aforementioned subject 23, please refer to Figure 3 The main body 23 includes a battery module 231 and a substrate 232. A receiving groove 232a is formed in the central region of the substrate 232, and the battery module 231 is disposed in the receiving groove 232a. Along the length direction a of the roof strip 1, the battery modules 231 of adjacent main bodies 23 are connected in series on the side facing the lower surface of the photovoltaic tile 2 by wires.

[0036] In some embodiments, the bottom of the receiving groove 232a is further provided with heat dissipation holes 232b, which penetrate the bottom of the receiving groove 232a. The heat dissipation holes 232b are used for heat exchange between the battery module 231 and the outside environment, and also serve to reduce the weight of the photovoltaic tile 2. To prevent rainwater and other liquids from flowing from the side facing the upper surface of the photovoltaic tile 2 to the side facing the lower surface of the photovoltaic tile 2 through the heat dissipation holes 232b, a sealant is further provided between the battery module 231 and the inner wall of the receiving groove 232a to seal the gap between the battery module 231 and the inner wall of the receiving groove 232a.

[0037] To prevent photovoltaic tile 2 from warping due to wind force during extreme weather conditions, please refer to [further details]. Figure 5 and Figure 6 In some embodiments, the photovoltaic tile 2 further includes a windproof fixing part 25. One end of the windproof fixing part 25 is connected to the photovoltaic tile 2, and along the arrangement direction b of the roof strips 1, the other end of the windproof fixing part 25 extends below the fourth end of the adjacent photovoltaic tile 2. The windproof fixing part 25 limits the third end of the photovoltaic tile 2 in a direction away from the fourth end of the adjacent photovoltaic tile 2. To achieve a better limiting effect, the windproof fixing part 25 and the third end of the photovoltaic tile 2 together clamp the fourth end of the adjacent photovoltaic tile 2.

[0038] Specifically, the first end of the windproof fixing part 25 is connected to the end of the main body 23 near the third end of the photovoltaic tile 2. The windproof fixing part 25 is elongated. The second end of the windproof fixing part 25 is formed by bending the first end of the windproof fixing part 25 along the direction of the fourth end of the photovoltaic tile 2 toward the third end of the photovoltaic tile 2. The fourth end of the photovoltaic tile 2 is also provided with an edge part 26, which is formed by bending the edge of the main body 23 along the direction of the upper surface of the photovoltaic tile 2 toward the lower surface of the photovoltaic tile 2. The edge part 26 is provided with an overlapping groove (not shown in the figure), and the second end of the windproof fixing part 25 abuts against the bottom of the overlapping groove. In some other embodiments, such as Figure 7 As shown, the second end of the windproof fixing part 25 may also be provided with a hook 251, which is used to engage with the edge part 26.

[0039] To prevent liquid on the surface of the photovoltaic tile 2 from flowing backwards from low to high in windy conditions, opposite to the arrangement direction of the roof strips 1, and subsequently seeping into the gap between the third and fourth ends of the photovoltaic tile 2, please refer to [further details]. Figure 2In some embodiments, the fourth end of the photovoltaic tile 2 is provided with an anti-backflow rib 27. The anti-backflow rib 27 is located on the upper surface of the photovoltaic tile 2 and extends from the first end of the photovoltaic tile 2 to the second end of the photovoltaic tile 2. The anti-backflow rib 27 is used to prevent the liquid in the drainage channel T from flowing back from low to high in the opposite direction to the arrangement direction b of the hanging strip 1.

[0040] Furthermore, in some embodiments, along the arrangement direction b of the roofing strips 1, the edge of the third end of the photovoltaic tile 2 crosses the anti-backflow rib 27 of the adjacent photovoltaic tile 2 and abuts against the upper surface of the adjacent photovoltaic tile 2. Specifically, along the arrangement direction of the roofing strips 1, the second abutting portion 24 crosses the anti-backflow rib 27 and abuts against the upper surface of the adjacent photovoltaic tile 2. Compared to configuring the second abutting portion 24 to abut against the upper surface S of the adjacent photovoltaic tile 2 on the side of the anti-backflow rib 27 facing away from the battery assembly 231, the second abutting portion 24 of this application crosses the anti-backflow rib 27 and then abuts against the upper surface S of the adjacent photovoltaic tile 2, which can avoid the formation of a gap that is prone to water accumulation between the second abutting portion 24 and the surface of the anti-backflow rib 27 of the adjacent photovoltaic tile 2 facing away from the battery assembly 231.

[0041] For the above-mentioned batten strip 1, please refer to Figure 5 and Figure 6 In this embodiment, a glue storage groove 11 is provided at the bottom of the tile strip 1. The glue storage groove 11 is used to inject fastening glue, and the tile strip 1 is fixed to the mounting surface Z by adhesive. A threaded hole 12 is provided at the top of the tile strip 1. A fixing part 28 is provided at the edge of the fourth end of the photovoltaic tile 2. The fixing part 28 includes a connecting part 281 and a mounting part 282. One end of the connecting part 281 is connected to the edge of the fourth end of the photovoltaic tile 2, and the other end of the connecting part 281 is connected to the mounting part 282. Along the direction from the upper surface of the photovoltaic tile 2 to the lower surface of the photovoltaic tile 2, the mounting part 282 is screwed and fixed to the threaded hole 12 to fix the photovoltaic tile 2 to the tile strip 1.

[0042] Furthermore, in this embodiment, the tile strip 1 is provided with a wire groove 13, which extends along the length direction a of the tile strip 1 and is used to accommodate the wires of the photovoltaic tile system 1000.

[0043] To accommodate mounting surfaces with different areas, please refer to [link / reference]. Figure 6 and Figure 8In some embodiments, the tile strip 1 is composed of several segments 14 that are detachably connected sequentially along the length direction a of the tile strip 1. By installing different numbers of segments 14, the total length of the tile strip 1 can be adjusted. Specifically, in some embodiments, the segments 14 are provided with connecting grooves 141, which penetrate the segments 14 along the length direction a of the tile strip 1. The tile strip 1 also includes a connector 15, which includes a limiting part 151, a clamping part 152, and a locking bolt (not shown). Along the length direction of the tile strip 1, the two ends of the limiting part 151 are respectively inserted into the connecting grooves 141 of two adjacent segments 14. Along the length direction perpendicular to the tile strip 1, the locking bolt passes through the clamping part 152 and the side wall W of the connecting groove 141 and is screwed and fixed to the limiting part 151. The clamping part 152 and the limiting part 151 are clamped and fixed to the side wall W of the connecting groove 141.

[0044] In the photovoltaic tile system of this application, along the length direction a of the roofing strip 1, the first arched portion 21 of the photovoltaic tile 2 is stacked on the second arched portion 22 of the adjacent photovoltaic tile 2, and the first abutting portion 211 abuts against the upper surface S of the adjacent photovoltaic tile 2. The first arched portion 21 and the second arched portion 22 cooperate with each other to prevent liquid from flowing from one side of the photovoltaic tile 2 to the other side through the gap at the connection between two adjacent photovoltaic tiles 2. In this way, the installation surface covered by the photovoltaic tile system 1000 of this application does not require additional waterproofing treatment, reducing the overall cost of using the photovoltaic tile system 1000.

[0045] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
