Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, and particularly relates to an eaves cover plate and photovoltaic system for a photovoltaic roof. Background Technology

[0002] With the popularization of distributed photovoltaic power generation, especially the rise of photovoltaic full-coverage roofs, people have not only raised their requirements for the practicality of photovoltaic arrays, but also their requirements for the appearance of photovoltaic arrays.

[0003] The structure and color of the photovoltaic array are usually inconsistent with the roof, which results in the original eaves structure of the roof being inconsistent with the appearance style of the photovoltaic array. Decorative covers can be installed at the edge of the photovoltaic array near the eaves. However, the existing eaves covers are not coordinated with the photovoltaic array surface and cannot adapt to the original roof drainage logic. Summary of the Invention

[0004] This invention provides an eaves cover for a photovoltaic roof, aiming to solve the problem that existing photovoltaic module eaves covers cannot simultaneously achieve both decoration and functionality.

[0005] The present invention is implemented as follows: an eaves cover for a photovoltaic roof, comprising:

[0006] The cover plate body includes an inclined surface parallel to the surface of the photovoltaic modules installed on the roof, and a vertical surface perpendicular to the horizontal plane; and

[0007] Angle bracket installed on the inclined surface,

[0008] The corner brackets are also connected to the photovoltaic modules to create drainage gaps between the slope and the photovoltaic modules.

[0009] Furthermore, the eaves cover also includes a connecting piece that connects to the vertical surface;

[0010] The connecting piece also connects to the eaves and walls of the house.

[0011] Furthermore, the end of the inclined plane away from the vertical plane is bent to form a first folded edge, and the corner bracket is installed on the first folded edge.

[0012] Furthermore, the first fold is perpendicular to the inclined plane.

[0013] Furthermore, the corner code includes an L-shaped first side and a second side;

[0014] The first side of the corner bracket is connected to the first folded edge, and the second side of the corner bracket is connected to the photovoltaic module.

[0015] Furthermore, a mounting bracket is provided on the side of the photovoltaic module facing the eaves, and the mounting bracket is connected to the second side of the corner bracket.

[0016] Furthermore, both sides of the inclined plane are bent to form a second folded edge.

[0017] Furthermore, the end of the vertical plane away from the inclined plane is bent to form a third fold, and the connecting piece is connected to the third fold.

[0018] Furthermore, both sides of the vertical plane are bent to form a fourth fold.

[0019] Secondly, this application also provides a photovoltaic system, including the eaves cover of the photovoltaic roof as described above.

[0020] The beneficial effects of this application are as follows: the main body of the cover plate is composed of a vertical surface and a sloped surface. The sloped surface is parallel to the surface of the photovoltaic module installed on the roof, and the sloped surface is also connected to the photovoltaic module through corner brackets, so that the sloped surface and the surface of the photovoltaic module can be coplanar for coordinated connection and good overall consistency. At the same time, the vertical surface is perpendicular to the horizontal surface, resulting in an aesthetically pleasing overall appearance. In addition, there is a drainage gap between the sloped surface and the photovoltaic module, through which water flowing from the surface of the photovoltaic module can flow to the roof, which can effectively adapt to the original drainage logic of the roof. While ensuring the overall aesthetic and decorative appearance of the eaves cover plate and photovoltaic module, it also meets the functional requirements of the drainage logic.

[0031] In this embodiment, the cover plate is composed of a vertical surface and a sloped surface. The sloped surface is parallel to the surface of the photovoltaic module installed on the roof, and it is also connected to the photovoltaic module through corner brackets, so that the sloped surface and the surface of the photovoltaic module can be coplanar for coordinated connection and good overall consistency. At the same time, the vertical surface is perpendicular to the horizontal surface, resulting in an aesthetically pleasing overall appearance. In addition, there is a drainage gap between the sloped surface and the photovoltaic module, through which water flowing from the surface of the photovoltaic module can flow to the roof, effectively adapting to the original drainage logic of the roof. While ensuring the overall aesthetic and decorative appearance of the eaves cover plate and photovoltaic module, it also meets the functional requirements of drainage logic.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, this embodiment provides an eaves cover for a photovoltaic roof, comprising:

[0034] The cover plate body 100 includes an inclined surface 110 parallel to the surface of the photovoltaic module 500 disposed on the roof 400, and a vertical surface 120 perpendicular to the horizontal plane; and

[0035] Angle bracket 200 installed on inclined surface 110

[0036] The corner bracket 200 is also connected to the photovoltaic module 500 so that there is a drainage gap 600 between the inclined surface 110 and the photovoltaic module 500.

[0037] In practice, roof 400 refers to the roof portion of a building. In some embodiments, roof 400 can be considered as roof tiles, but this is not a limitation.

[0038] Optionally, a photovoltaic array is installed on the roof 400. The photovoltaic array is usually composed of multiple photovoltaic modules, each of which can be regarded as a solar panel, which will not be elaborated here.

[0039] Optionally, the cover plate body 100 is composed of a sloped surface 110 and a vertical surface 120. When the cover plate body 100 is installed on the roof eaves, the sloped surface 110 is parallel to the surface of the photovoltaic module and is integrated with the photovoltaic array on the roof 400. At the same time, the vertical surface 120 is perpendicular to the horizontal plane and can cover the original tiles and drainage ditches of the eaves, making the overall appearance beautiful and harmonious.

[0040] Optionally, the inclined surface 110 and the vertical surface 120 are made using a one-piece plate bending process. The included angle between the inclined surface 110 and the vertical surface 120 can be adjusted according to the actual installation environment, and is not limited here.

[0041] Optionally, the corner bracket 200 is used to connect the inclined surface 110 and the photovoltaic module 500. In some embodiments, the corner bracket 200 can be installed at the end of the inclined surface 110 away from the vertical surface 120. Optionally, multiple corner brackets 200 can be installed at the end of the inclined surface 110 away from the vertical surface 120. The multiple corner brackets 200 are arranged at intervals, which can effectively improve the connection structure strength between the cover plate body 100 and the photovoltaic module 500.

[0042] Optionally, a drainage gap 600 is provided between the slope 110 and the photovoltaic module 500. The drainage gap 600 allows water flowing from the surface of the photovoltaic module 500 to flow onto the roof 400 and then be discharged from the roof 400 to a designated location. For example, an eaves drainage ditch 700 is also provided at the corresponding eaves position. Water flowing onto the roof 400 can be discharged into the eaves drainage ditch 700 and further discharged to a designated location, such as a sewer, etc., which will not be elaborated here.

[0043] In some possible embodiments, there is a certain gap between the cover plate body 100 and the eaves of the roof 400, so that the space below the cover plate body 100 is open, allowing air to enter and exit smoothly, which is beneficial for ventilation and heat dissipation at the bottom of the photovoltaic array. Similarly, the drainage gap between the inclined surface 110 and the photovoltaic module 500 can also be used for ventilation and heat dissipation, further improving the heat dissipation effect of the photovoltaic array.

[0044] This application uses a cover plate body 100 composed of a vertical surface 120 and an inclined surface 110. The inclined surface 110 is parallel to the surface of the photovoltaic module 500 installed on the roof 400, and the inclined surface 110 is also connected to the photovoltaic module 500 through a corner bracket 200, so that the inclined surface 110 can be coplanar with the surface of the photovoltaic module 500 for coordinated connection and good overall consistency. At the same time, the vertical surface 120 is perpendicular to the horizontal surface, resulting in an aesthetically pleasing overall appearance. In addition, there is a drainage gap 600 between the inclined surface 110 and the photovoltaic module 500, through which water flowing from the surface of the photovoltaic module 500 can flow to the roof 400, effectively adapting to the original drainage logic of the roof 400. While ensuring the overall aesthetic and decorative appearance of the eaves cover plate body 100 and the photovoltaic module 500, it also meets the functional requirements of the drainage logic.

[0045] Example 2

[0046] Furthermore, the eaves cover provided in this application also includes a connecting piece 300 connected to the vertical surface 120;

[0047] The connecting piece 300 is also connected to the eaves wall 800 of the house.

[0048] Optionally, the connecting piece 300 connects the vertical surface 120 and the eaves wall 800, which can further improve the installation stability of the cover plate body 100.

[0049] Optionally, the vertical surface 120 can also be connected to the eaves wall 800 of the house through multiple connecting pieces 300. The multiple connecting pieces 300 are arranged at intervals, which can effectively improve the structural strength of the connection between the vertical surface 120 and the eaves wall 800 of the house.

[0050] In some embodiments, the connecting piece 300 can be adapted to bend before installation for different eaves wall surfaces 800, and can be used for different entry and exit deviations to ensure the perpendicularity of the vertical surface 120 to the horizontal surface.

[0051] Optionally, the connection between the connecting piece 300 and the vertical surface 120 can be achieved using screws, rivets, bolts, or welding, etc., without limitation. For example, both ends of the connecting piece 300 are provided with through holes for screws, rivets, bolts, etc., to pass through for installation connection.

[0052] Example 3

[0053] Furthermore, the end of the inclined plane 110 away from the vertical plane 120 is bent to form a first folded edge 111, and the corner bracket 200 is installed on the first folded edge 111.

[0054] Optionally, the first fold 111 is formed by bending the inclined surface 110. Preferably, the first fold 111 is perpendicular to the inclined surface 110, which can effectively improve the structural strength of the inclined surface 110.

[0055] In implementation, the first folded edge 111 and the corner bracket 200 can be installed using rivets, screws, or welding, etc., without limitation. For example, the first folded edge 111 is formed by bending one end of the inclined surface 110 away from the vertical surface 120 along a first direction, which is perpendicular to the inclined surface 110 and downwards. During installation, this effectively conceals the corner bracket 200, making the overall appearance of the cover plate body 100 and the photovoltaic module 500 more aesthetically pleasing and unified. Optionally, the cover plate body 100 can also be designed with a color similar to or consistent with the photovoltaic module, making the overall roof color more unified.

[0056] It should be noted that the downward direction mentioned above refers to the direction from the inclined surface 110 towards the roof 400 and perpendicular to the inclined surface 110 when the eaves cover is installed at the edge of the eaves of the roof 400. Figure 2 As shown, direction a is the downward direction, which will not be elaborated here.

[0057] Example 4

[0058] Furthermore, the corner code 200 includes an L-shaped first side 210 and a second side 220;

[0059] The first side 210 of the corner bracket is connected to the first folded edge 111, and the second side 220 of the corner bracket is connected to the photovoltaic module 500.

[0060] In practice, the first side 210 and the second side 220 of the corner code are in an L-shape. In some embodiments, the first side 210 and the second side 220 of the corner code can also be at a right angle.

[0061] Optionally, both the first side 210 and the second side 220 of the corner bracket are provided with through holes. In some embodiments, these through holes allow rivets or the like to pass through to achieve connections between the first folded edge 111 and the first side 210 of the corner bracket, and between the photovoltaic module 500 and the second side 220 of the corner bracket. For example, the first side 210 of each corner bracket 200 is connected to the first folded edge 111 by two rivets, which effectively improves the connection strength.

[0062] In other embodiments, these through holes may also be threaded holes to enable connection between the first folded edge 111 and the first side 210 of the corner bracket, and between the photovoltaic module 500 and the second side 220 of the corner bracket, by means of screws or bolts.

[0063] During implementation, bending the first fold 111 downwards can also allow the aforementioned rivets, screws, or bolts to be installed in the drainage gap 600, preventing the rivets, screws, or bolts from being exposed and affecting the aesthetics.

[0064] Example 5

[0065] Furthermore, a mounting component 510 is provided on the side of the photovoltaic module 500 facing the eaves, and the mounting component 510 is connected to the second side 220 of the corner bracket.

[0066] During implementation, the mounting component 510 is installed on the side of the photovoltaic module 500. The side of the photovoltaic module 500 refers to the side adjacent to the surface of the photovoltaic module 500. Normally, the surface of the photovoltaic module 500 and the side are perpendicular to each other, which will not be elaborated here.

[0067] Optionally, the mounting component 510 can be regarded as a corner bracket. For example, the mounting component 510 includes two sides, one side being connected to the side of the photovoltaic module 500, for example, by screwing onto the side of the photovoltaic module 500, and the other side being connected to the second side 220 of the corner bracket, for example, by screwing the other side to the second side 220 of the corner bracket.

[0068] Example 6

[0069] Furthermore, both sides of the inclined plane 110 are bent to form a second folded edge 112.

[0070] In practice, the second fold 112 can be perpendicular to the inclined plane 110, which can effectively improve the structural strength of the inclined plane 110.

[0071] Example 7

[0072] Furthermore, the end of the vertical surface 120 away from the inclined surface 110 is bent to form a third fold 121, and the connecting piece 300 is connected to the third fold 121.

[0073] Furthermore, both sides of the vertical plane 120 are bent to form a fourth folded edge 122.

[0074] In implementation, the third fold 121 and the fourth fold 122 can effectively improve the structural strength of the vertical surface 120. Optionally, the inclined surface 110 and the vertical surface 120 are made by a one-piece plate bending process, and the bending process produces the first fold 111, the second fold 112, the third fold 121 and the fourth fold 122. These folds act as reinforcing ribs for the inclined surface 110 and the vertical surface 120, so that the cover plate body 100 as a whole has good strength and rigidity.

[0075] Optionally, when the cover plate body 100 is installed at the eaves position of the roof 400, the third folded edge 121 is parallel to the horizontal plane, which can effectively improve the aesthetics of the eaves cover plate.

[0076] Optionally, one end of the connecting piece 300 is connected to the third folded edge 121 by two rivets, which can effectively improve the connection strength between the connecting piece 300 and the third folded edge 121.

[0079] Those skilled in the art will clearly understand that, for the sake of convenience and indirectness, the structure and implementation principle of the photovoltaic system described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments one to seven, and will not be repeated here.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
