The mounting screws install the lowest mounting piece on the tile hanging strip, but after fixing, the installation position of the photovoltaic tile cannot be adjusted. In addition, when the photovoltaic tiles need to be operated and maintained, it is also necessary to remove the mounting screws first and then disassemble the photovoltaic tiles, which is relatively cumbersome. [Utility Model Content]

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a photovoltaic tile installation structure and a photovoltaic system that are convenient for adjusting the installation position, so that the installation position of the photovoltaic tiles can be easily adjusted, and the photovoltaic tiles can be disassembled without removing the fasteners during operation and maintenance.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] First, a photovoltaic tile mounting structure that is convenient for adjusting the mounting position is provided, wherein at least two photovoltaic tiles are installed at an inclination along the longitudinal direction and are arranged in a stepped manner from front to back, the longitudinal front side of the photovoltaic tile has a first longitudinal frame, and the longitudinal rear side has a second longitudinal frame, the photovoltaic tile mounting structure includes a tile hanging member and a fixed edge arranged at the bottom of the second longitudinal frame, the fixed edge is provided with a mounting hole, a fastener is connected between the tile hanging member and the mounting hole, the mounting hole is provided with an adjusting portion and a fixing portion, the mounting hole is adjusted relative to the fastener through the adjusting portion to adjust the mounting position of the photovoltaic tile or separate the fastener from the mounting hole, and the fastener is fixed to the mounting hole through the fixing portion.

[0006] Preferably, the mounting hole is a triangular structure, the adjusting portion is located in the central area of ​​the triangle, and the fixing portion is located at the corners of the triangle.

[0007] Preferably, the fixing edge is L-shaped, comprising a rear side edge and an upper side edge connected vertically, wherein the rear side edge is limitedly matched with the rear side surface of the tile hanging member, and the upper side edge is fixed to the upper surface of the tile hanging member by fasteners.

[0008] Preferably, the fastener is a self-tapping screw, which passes through the mounting hole and is fixed to the fixing portion.

[0009] Preferably, in two longitudinally adjacent photovoltaic tiles, the second longitudinal frame is fixed to the tile hanging member, the second longitudinal frame is provided with a limit buckle, the first longitudinal frame is provided with a lower limit rib, and the limit buckle is limitedly matched with the lower limit rib.

[0010] Preferably, the second longitudinal frame is provided with a sliding groove extending laterally, and the limiting buckle is provided with a slider, and the slider cooperates with the sliding groove.

[0011] Preferably, the slider and the slide groove are T-shaped structures.

[0012] Preferably, the limit buckle is provided with an upper limit rib extending obliquely forward, and the lower limit rib extends obliquely backward and extends under the upper limit rib.

[0013] Preferably, a transversely extending water retaining strip is provided on the bottom surface of the first longitudinal frame in front of the second longitudinal frame.

[0014] In addition, a photovoltaic system is provided, comprising a plurality of photovoltaic tiles, wherein the photovoltaic tiles are installed using the installation structure.

[0015] The utility model adopts the above technical solution, which has the following beneficial effects:

[0016] 1. At least two photovoltaic tiles are installed longitudinally and tilted and arranged in a stepped manner from front to back, wherein the second longitudinal frame of the photovoltaic tile is fixed to the tile hanging member, while the first longitudinal frame is not fixed; a mounting hole is provided on the fixed side at the bottom of the second longitudinal frame, and since the mounting hole is provided with an adjusting portion and a fixing portion, the mounting hole is adjusted relative to the fastener through the adjusting portion to adjust the installation position of the photovoltaic tile, ultimately ensuring that the installation position of the photovoltaic tile meets the requirements, and the fastener is finally fixed to the mounting hole through the fixing portion.

[0017] During operation and maintenance of photovoltaic tiles, the characteristics of the mounting holes can also be utilized to move the photovoltaic tiles. After the adjustment part corresponds to the position of the fasteners, the fasteners are separated from the mounting holes and the photovoltaic tiles can be removed without removing the fasteners.

[0018] Therefore, the utility model can not only adjust the installation position of the photovoltaic tile according to actual conditions, but also can disassemble the photovoltaic tile without removing the fasteners during operation and maintenance.

[0019] 2. The fixed edge is L-shaped, in which the rear side is limited with the rear side of the tile hanging piece to determine the front and rear relative positions of the fixed edge and the tile hanging piece, and then the upper side is fixed to the upper surface of the tile hanging piece with fasteners.

[0020] 3. The fasteners are preferably self-tapping screws, which eliminate the need for pre-drilling. They are efficient and convenient, have strong adhesion and good compatibility.

[0021] Because the mounting hole is triangular, the central area is much larger than the external dimensions of the self-tapping screw head, and the width of the corners is smaller than the diameter of the self-tapping screw head. The installation position of the photovoltaic tile can be adjusted according to actual conditions and fixed with self-tapping screws. In addition, during operation and maintenance of the photovoltaic tile, the characteristics of the triangular hole can also be used to remove the photovoltaic tile without removing the self-tapping screws.

[0022] 4. Since the first longitudinal frame is not fixed, in order to prevent the photovoltaic tiles from falling off due to strong winds or other extreme weather, the second longitudinal frame is connected to a limit buckle. The first longitudinal frame is provided with a lower limit rib, and the limit buckle cooperates with the lower limit rib. Therefore, the limit buckle cooperates with the upper surface of the second longitudinal frame to limit the lower limit rib of the first longitudinal frame up and down, preventing the photovoltaic tiles from flipping upward from the first longitudinal frame during strong winds or other extreme weather.

[0023] 5. In order to prevent the limit buckle from affecting the installation of photovoltaic tiles, the limit buckle is designed to be a detachable structure, and a slider can be used to slide with the slide groove. In this way, after the second longitudinal frame is fixed to the tile hanging piece, the limit buckle can be inserted into the slide groove and pushed horizontally to install the limit buckle.

[0024] 6. There is a certain spacing height between the upper limit rib and the upper surface of the second longitudinal frame. The lower limit rib extends obliquely backward and extends under the upper limit rib, and the upper limit rib limits the lower limit rib.

[0025] 7. A transversely extending water retaining strip is provided on the bottom surface of the first longitudinal frame in front of the second longitudinal frame. The water retaining strip can play a waterproof role. When backflow occurs between the front and rear photovoltaic tiles, the water is blocked by the water retaining strip and falls on the front photovoltaic tiles and drains away.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

[0037] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0038] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0039] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "front," "back," "horizontal," and "vertical" used below to indicate directions or positional relationships are based solely on the directions or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction or be constructed or operated in a specific direction. Therefore, they should not be understood as limiting the utility model.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0042] Reference Figures 1 to 8 , and combined with the photovoltaic system installed on the sloping roof in the prior art, a number of photovoltaic tiles 100 are arranged in a rectangular array on the sloping roof 2. In the entire photovoltaic array, at least two photovoltaic tiles 100 are arranged side by side in the horizontal direction, and at least two photovoltaic tiles 100 are arranged side by side in the vertical direction. The two photovoltaic tiles 100 arranged side by side in the horizontal direction maintain a flat surface, and the two photovoltaic tiles 100 adjacent to each other in the horizontal direction are connected by a horizontal buckle structure. At least two photovoltaic tiles arranged side by side in the vertical direction are installed obliquely in the vertical direction and arranged in steps from front to back. The rear end of the front photovoltaic tile is located below the front end of the rear photovoltaic tile, resembling a tile arrangement structure. And the two photovoltaic tiles 100 adjacent to each other in the vertical direction are connected by an oblique overlap structure. In addition, in order to install photovoltaic tiles, the sloping roof 2 is provided with a number of water strips 21 arranged side by side in the horizontal direction. The water strips 21 are installed obliquely in the vertical direction. A tile hanging member 22 is installed on the water strips 21. The tile hanging member 22 is a rectangular strip structure that extends in the horizontal direction and is perpendicular to the water strips. It is also called a tile hanging strip.

[0043] Photovoltaic tiles are common photovoltaic modules with four frames: front, rear, left (first horizontal side), and right (second horizontal side). While the structure of each frame is identical in the prior art, in this embodiment, the structures of each frame are different. The photovoltaic tiles are installed from right to left and from front (diagonally downward) to back (diagonally upward). The left and right frames of the photovoltaic tiles are connected by a transverse snap-fit ​​structure, while the upper and lower frames are connected by a diagonal overlap structure, thereby achieving waterproofing. Using photovoltaic tiles instead of traditional roof tiles as a waterproof component eliminates the need for hooks and other structural components for installation, forming a reliable overall waterproof structure.

[0044] Reference Figure 7 and Figure 8 As shown, the photovoltaic tile transverse interlocking structure in this embodiment includes two photovoltaic tiles 100 arranged side by side in the transverse direction, wherein one photovoltaic tile has a first transverse frame 14 on the second transverse side, and the other photovoltaic tile has a second transverse frame 15 on the first transverse side. One of the first transverse frame 14 and the second transverse frame 15 has a drainage groove 151 extending longitudinally at the bottom and transversely outward of the first transverse frame 14 and the second transverse frame 15 has a waterproof portion 141 extending longitudinally at the top and transversely outward of the other. The waterproof portion 141 is interlocked above the drainage groove 151. In the example shown in the figure, the waterproof portion 141 is provided on the first transverse frame 14, and the drainage groove 151 is provided on the second transverse frame 15. The photovoltaic tile 100 is installed from the second transverse side (right) to the first side (left), so that the second transverse frame 15 is interlocked with the first transverse frame 14 from top to bottom, and the waterproof portion 141 is interlocked above the drainage groove 151.

[0045] Furthermore, the waterproof portion 141 includes a waterproof top wall 1411 and side edges 1412 extending vertically downward from the edge of the waterproof top wall. The side edges 1412 are aligned with the lateral outer side of the opposite transverse frame. The drainage groove 151 includes a groove bottom wall 1511 and groove side walls 1512 extending vertically upward from the edge of the groove bottom wall. The groove side walls 1512 are aligned with the lateral outer side of the opposite transverse frame. Because the side edges of the waterproof portion are aligned with the lateral outer side of the opposite transverse frame, there is essentially no gap between the two. Even a small amount of water that seeps through the gap will enter the drainage groove and be discharged from the drainage groove. Because the groove side walls of the drainage groove are aligned with the lateral outer side of the opposite transverse frame, there is essentially no gap between the two, and thus water leakage is not easy.

[0046] Furthermore, the drainage trough 151 includes a reinforcing rib 1513 extending vertically upward from the middle of the bottom wall 1511. This increases the overall structural strength of the drainage trough 151. The bottom wall 1511 and the waterproof top wall 1411 are both provided with cavities, saving material and reducing costs.

[0047] like Figure 8As shown, the top surface of the waterproof portion 141 is flush with the top surface of the transverse frame. The width of the waterproof portion 141 is equal to the width of the drainage groove. This achieves a substantially seamless transverse interlocking structure, and the top surfaces of two adjacent transverse frames are flush. This photovoltaic tile transverse interlocking structure is not only effective in waterproofing but also smooth and aesthetically pleasing. A gap L is provided between the side edge 1412 and the groove bottom wall 1511, as well as between the groove side wall 1512 and the waterproof top wall 1411. This ensures that the top surfaces of the two adjacent transverse frames remain flush after installation.

[0048] Reference Figures 1 to 3 As shown, the obliquely overlapped photovoltaic tile structure in this embodiment includes at least two photovoltaic tiles 100 installed longitudinally at an angle and arranged in a stepped manner from front to back. The photovoltaic tiles 100 have a first longitudinal frame 11 on the longitudinal front side and a second longitudinal frame 12 on the longitudinal rear side. Furthermore, a tile hanging member 22 also serves as part of the obliquely overlapped structure. In two longitudinally adjacent photovoltaic tiles 100, the second longitudinal frame 12 is fixed to the tile hanging member 22. The second longitudinal frame 12 is provided with a retaining buckle 13, and the first longitudinal frame 11 is provided with a lower retaining edge 111. The retaining buckle 13 cooperates with the lower retaining edge 111 to limit the position.

[0049] At least two photovoltaic tiles are installed in a longitudinally inclined manner and arranged in steps from front to back. The installation order is from front (diagonally downward) to back (diagonally upward). For the two photovoltaic tiles connected by the diagonal overlap structure, since only the second longitudinal frame needs to be fixed to the tile hanging member, and the first longitudinal frame is not fixed, the installation is convenient and requires fewer installation components, which solves the problem of low installation efficiency of existing conventional photovoltaic tiles.

[0050] Since the first longitudinal frame is not fixed, in order to prevent the photovoltaic tiles from falling off due to strong winds or other extreme weather, the second longitudinal frame is connected to a limit buckle. The first longitudinal frame is provided with a lower limit rib, and the limit buckle cooperates with the lower limit rib. Therefore, the limit buckle cooperates with the upper surface of the second longitudinal frame to limit the lower limit rib of the first longitudinal frame up and down, preventing the photovoltaic tiles from flipping upward from the first longitudinal frame during strong winds or other extreme weather.

[0051] In order to prevent the limit buckle from affecting the installation of photovoltaic tiles, the limit buckle is designed to be a detachable structure. As one of the implementation methods, Figure 2 As shown, the second longitudinal frame 12 is provided with a transversely extending slot 121, and the retaining buckle 13 is provided with a slider 131 that slidably engages with the slot 121. Preferably, the slider 131 and the slot 121 form a T-shaped structure. Thus, after the second longitudinal frame is secured to the tile hanging member, the retaining buckle can be installed by inserting it into the slot and pushing it laterally, facilitating the quick, diagonal connection of two photovoltaic tiles.

[0052] Specifically, such as Figure 2As shown, the limit buckle 13 is provided with an upper limit rib 132 extending obliquely forward, with a certain height gap between the upper limit rib 132 and the upper surface of the second longitudinal frame 12. The lower limit rib 111 extends obliquely backward and extends below the upper limit rib 132. A circular arc transition section 133 is provided between the upper limit rib 132 and the slider 131.

[0053] Furthermore, a transversely extending water barrier 112 is provided on the bottom surface of the first longitudinal frame 11, in front of the second longitudinal frame 12. The water barrier can be integrally formed with the first longitudinal frame 11, or can be installed by snap-fitting, i.e., by installing a rubber strip as the water barrier. The water barrier is in close contact with the second longitudinal frame 12, providing a waterproof effect. When water flows back between the front and rear photovoltaic tiles, the water is blocked by the water barrier and flows onto the front photovoltaic tile.

[0054] In order to fix the second longitudinal frame, as Figure 2 and Figure 3 As shown, the bottom of the second longitudinal frame 12 is provided with an L-shaped fixed edge 122, which includes a vertically connected rear side edge 1221 and an upper side edge 1222. The rear side edge 1221 is limitedly engaged with the rear side of the tile hanging member, and the upper side edge 1222 is fixed to the upper surface of the tile hanging member using fasteners, specifically self-tapping screws. The upper side edge 1222 is provided with mounting holes 1223, and the self-tapping screws pass through the mounting holes 1223 to secure the tile hanging member.

[0055] After fixing with self-tapping screws, it cannot guarantee that the installation position of the photovoltaic tile meets the requirements. In addition, the photovoltaic tile needs to be disassembled during operation and maintenance. In order to be able to adjust the installation position of the photovoltaic tile according to actual conditions, and to disassemble the photovoltaic tile without removing the self-tapping screws during operation and maintenance. The mounting hole 1223 is provided with an adjustment part and a fixing part. During installation, the adjustment part is used to adjust the position of the mounting hole relative to the fastener, ultimately ensuring that the installation position of the photovoltaic tile meets the requirements, and the fastener is finally fixed to the mounting hole through the fixing part. Specifically, Figure 3 As shown, the mounting hole 1223 is a triangular structure, the adjustment portion is located in the central area of ​​the triangle, and the fixing portion is located at the corners of the triangle. Because the mounting hole is a triangle, the central area is much larger than the external dimensions of the self-tapping screw head, and the width of the corners is smaller than the diameter of the self-tapping screw head. The installation position of the photovoltaic tile can be adjusted according to actual conditions and fixed with self-tapping screws. In addition, when the photovoltaic tile needs to be operated and maintained, the characteristics of the triangular hole can be used to remove the photovoltaic tile without removing the self-tapping screws. It is understandable that in order to achieve adjustability, the mounting hole can also be other shapes, not limited to triangles.

[0056] Sometimes, due to space limitations, the sloping roof 2 is not fully covered with photovoltaic tiles, especially when there is still some space in front of the photovoltaic array that cannot meet the size of the photovoltaic tiles to be installed. To avoid exposure, a row of flat tiles 23 are laid horizontally in front of the photovoltaic array on the sloping roof 2. The flat tiles 23 are usually prefabricated cement parts. Figures 4 to 6 As shown, a flat tile 23 is also provided in front of the photovoltaic tile at the longitudinal front end. In order to fix the flat tile and limit the front side of the photovoltaic tile at the longitudinal front end, a hanging tile 22 is provided below the first longitudinal frame of the photovoltaic tile at the longitudinal front end. The two hanging tile 22 are arranged side by side in the longitudinal direction, wherein the longitudinal rear end of the flat tile is fixed to the longitudinal front hanging tile, and the longitudinal rear hanging tile is connected to a starting card 24. The starting card 24 is a Z-shaped structure, including a bottom edge 241 and a top edge 242, wherein the bottom edge 241 is fixed to the upper surface of the hanging tile by self-tapping screws, and the top edge 242 extends obliquely forward to form an upper limit rib. Referring to the above description, since the first longitudinal frame is provided with a lower limit rib, the upper limit rib cooperates with the lower limit rib, and the first longitudinal frame of the photovoltaic tile at the longitudinal front end can also be limited.

[0057] Specifically, such as Figure 5 As shown, the longitudinal rear end of the flat tile 23 is fixed to the tile hanging piece 22 by using self-tapping screws, and the longitudinal rear end of the flat tile 23 is provided with an overlapping portion 231 inserted into the gap between the two tile hanging pieces, so as to reliably fix the rear end of the flat tile.

[0058] Further, such as Figure 6 As shown, a tile hanging member 22 is installed above the front end of the water-smoothing strip 21, and a sealing perforated plate 25 is fixed to the front end of the tile hanging member. The sealing perforated plate 25 is an L-shaped structure, including a rear side wall 251 and an upper side wall 252 connected vertically. The rear side wall 251 is attached to the tile hanging member 22 and the front side of the water-smoothing strip 21 and is fixed with self-tapping screws respectively, and the upper side wall 252 is supported on the bottom surface of the flat tile.

[0059] The at least two photovoltaic tiles installed longitudinally and arranged in a stepped pattern from front to back should be installed from front (diagonally downward) to back (diagonally upward). The frontmost photovoltaic tile should be installed first. Before installing the frontmost photovoltaic tile, the starting clamp should be installed on the tile hanging member, with the upper limit flange of the starting clamp positioned above the flat tile. The lower limit flange of the photovoltaic tile should extend between the upper limit flange of the starting clamp and the flat tile. The first longitudinal frame should then be secured with self-tapping screws through the mounting holes.

[0060] Next, install the photovoltaic tiles on the rear side in turn, slide the limit buckle with the slide groove to connect it to the second longitudinal frame, and the lower limit guard of the first longitudinal frame of the rear photovoltaic tile extends into the space between the limit buckle and the second longitudinal frame of the front photovoltaic tile. The limit buckle serves to limit the rear photovoltaic tile.

[0061] When the photovoltaic tile needs maintenance, you can push the photovoltaic tile so that the center of the installation hole is aligned with the nail head of the self-tapping screw, and remove it from the self-tapping screw to facilitate the operation and maintenance of the photovoltaic tile.

[0062] Preferably, the first transverse frame, the second transverse frame, the first longitudinal frame, the second longitudinal frame, and the stop buckle can be made of aluminum alloy or stainless steel, for example, aluminum alloy or stainless steel profiles. This can be industrialized, significantly reducing costs, and has high strength, is not easily corroded, and has a long service life.

[0063] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
