Description

Technical Field

[0001] The invention belongs to the field of solar photovoltaic power generation and relates to a photovoltaic tile and a rapid installation method. Background Art

[0002] Optimize the energy structure of urban construction. Promote the integrated construction of building solar photovoltaics, and strive to achieve a 50% photovoltaic coverage rate on the roofs of new public institution buildings and new factory buildings by 2025. Among them, BIPV is the main technical route for photovoltaic buildings. As a type of BIPV, photovoltaic tiles have both architectural functions and power generation functions. Once launched, they have received widespread attention. The photovoltaic tiles laid on the roof must have a reasonable force structure, meet the requirements of wind resistance and drainage, and ensure that the laid photovoltaic tiles can work stably and permanently, while being compatible with traditional roof tiles.

[0003] Some existing photovoltaic tile products have low installation efficiency due to structural limitations, and there is room for further improvement. They are also not very resistant to wind resistance and wind uplift, and have surface dust accumulation problems similar to other photovoltaic solar panels. Summary of the invention

[0004] The purpose of the present invention is to provide a photovoltaic tile and a quick installation method to address the problems of low installation efficiency and weak wind resistance and wind-tightening resistance of existing photovoltaic tiles due to structural limitations, as well as the problem of surface dust accumulation similar to other photovoltaic solar modules. The photovoltaic tiles of the present invention are matched with mainstream solar cells to achieve higher power generation efficiency, and adopt an upper and lower overlap structure to achieve quick installation, full roof paving, stable structure, excellent mechanical properties, and wind resistance and wind-tightening resistance. At the same time, the lower frame of the photovoltaic tile of the present invention adopts a no-A-side design, which can meet the load requirements while achieving the effect of not accumulating dust by flushing with rainwater. In addition, the photovoltaic tile adopts a left-right buckle design in structural design, so that it has a drainage function.

[0005] The technical solution adopted by the present invention is:

[0006] A photovoltaic tile comprises a photovoltaic module and four frames, wherein the photovoltaic module is embedded in the four frames, and the four frames are respectively a first frame, a second frame, a third frame and a fourth frame. In the actual installation process of the photovoltaic tile, the first direction D1 is the roof slope direction, and the second direction D2 is the roof width direction; the photovoltaic tile has a first frame and a second frame relative to each other along the first direction D1, and has a third frame and a fourth frame relative to each other along the second direction D2; the characteristics are as follows: the first frame comprises a burr buckle, a first frame lower surface, and a first frame mounting surface, and a plurality of equidistant mounting holes are evenly distributed on the first frame mounting surface, and the photovoltaic tile is fixedly connected with the roof tile purlin through the mounting holes on the first frame mounting surface; the frame edge of the photovoltaic module buckled on the upper part of the first frame has a burr buckle, which forms an interlocking structure with the lower part of the second frame of the adjacent photovoltaic tile, which can resist wind exposure, improve the wind resistance resistance of the photovoltaic tile, and has a waterproof function. The first frame mounting surface and the roof tile purlin are tightly fitted to each other, which can realize the rapid positioning and installation of the photovoltaic roof. The equidistant mounting holes are evenly distributed on the first frame mounting surface and are used to fix the photovoltaic tiles on the roof tile hanging purlins.

[0007] There is an angle between the first frame mounting surface and the lower surface of the first frame, 60 degrees < angle < 90 degrees, and the first frame mounting surface and the lower surface of the first frame are not perpendicular. This is because a certain inclination angle is required during the actual installation process to meet the matching relationship between the photovoltaic tiles and the sloping roof.

[0008] The first frame mounting surface serves to fix the entire photovoltaic tile, so the thickness will be increased to ensure the required installation strength. Reinforcing ribs are provided at the angle formed by the first frame mounting surface and the lower surface of the first frame to enhance strength and rigidity and reduce damage caused by stress concentration.

[0009] The second frame includes a second frame upper surface, and the second frame adopts the A-side design of the non-snap photovoltaic module, that is, the second frame upper surface is flush with the upper surface glass of the photovoltaic module.

[0010] Since there is no frame to block the A side, rainwater will not gather. This design can make good use of rainwater to wash the photovoltaic tiles and reduce the dust accumulation on the surface of the photovoltaic tiles.

[0011] There is no height difference between the second frame and the photovoltaic module, which is conducive to rainwater washing the photovoltaic tiles and reducing dust accumulation on the surface of the photovoltaic tiles.

[0012] When the first frame and the second frame are overlapped, the lower part of the second frame is snapped with the flash snap of the frame edge of the photovoltaic assembly at the upper part of the first frame of the adjacent photovoltaic tile below in the first direction D1.

[0013] The burr buckle on the upper part of the first frame is straight or curved with a certain curvature.

[0014] The burr buckle on the upper part of the first frame is in a curved arc shape, and the part where the second frame contacts the burr buckle on the upper part of the first frame also presents a certain curvature, forming a concave-convex complementary structure.

[0015] In an embodiment of the present application, the novel photovoltaic tile also includes a third frame and a fourth frame, and the third frame and the fourth frame are respectively connected to the fourth frame and the third frame of the adjacent photovoltaic tile on the left and right sides, and the formed left and right connected sub-frame structure can also serve as a water guide trough.

[0016] The third frame or the fourth frame of the photovoltaic tile can be buckled with the traditional tile, and is compatible with the installation method of the traditional tile, so as to be integrated with the traditional roof, thereby improving the integration degree of the photovoltaic tile and the conventional tile.

[0017] The method for quickly installing photovoltaic tiles, during the photovoltaic tile installation process, the first direction D1 is the roof slope direction, the second direction D2 is the roof width direction, and it is characterized by the following steps:

[0018] Step 1: along the first direction D1, with the crystalline silicon cell side of the photovoltaic tile facing the sky, align the fourth frame of the first photovoltaic tile with the edge of the roof, and fix the first photovoltaic tile with the roof tile purlin through the mounting hole on the mounting surface of the first frame; after the second frame of the second photovoltaic tile is snapped with the flash buckle of the frame edge of the upper buckle photovoltaic module of the first frame of the first photovoltaic tile, the mounting hole on the mounting surface of the first frame of the second photovoltaic tile is fixedly connected with the roof tile purlin; all photovoltaic tiles are installed in sequence along this direction;

[0019] Step 2: Install the adjacent photovoltaic tiles along the second direction D2 to the first photovoltaic tile installed in step 1. The adjacent photovoltaic tiles form a left-right buckled structure that cooperates with the first photovoltaic tile along this direction. Buckle the fourth frame of the adjacent photovoltaic tile to the third frame of the first photovoltaic tile. Then fix the mounting holes on the mounting surface of the first frame of the adjacent photovoltaic tile to the roof tile purlin. Install the photovoltaic tiles in this direction along the first direction D1 in sequence. Install them in the same way until the entire roof is installed.

[0020] The photovoltaic tiles of the present invention are matched with mainstream solar cells to achieve higher power generation efficiency. They adopt an upper and lower overlap structure to achieve quick installation, can be laid on the entire roof, have a stable structure, excellent mechanical properties, and can resist wind and resist wind. At the same time, the lower frame of the photovoltaic tiles without dust accumulation of the present invention adopts a non-A-side design, which can meet the load requirements while achieving the effect of using rainwater to flush without dust accumulation. In addition, the photovoltaic tiles adopt a left-right buckle design in the structural design, so that they also have drainage function. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0037] like Figure 1 , Figure 2 As shown, a photovoltaic tile 100 of the present invention includes a photovoltaic module and four frames. The photovoltaic module is embedded in the four frames. The four frames are respectively a first frame 110, a second frame 120, a third frame 130 and a fourth frame 140. During the actual installation of the photovoltaic tile 100, the first direction D1 is the roof slope direction, and the second direction D2 is the roof width direction; the photovoltaic tile 100 has a relative first frame 110 and a second frame 120 along the first direction D1, and has a relative third frame 130 and a fourth frame 140 along the second direction D2.

[0038] like Figure 3 As shown, in the embodiment of the present invention, the first frame 110 includes a flash buckle 111, a first frame lower surface 113, and a first frame mounting surface 114. A plurality of equidistant mounting holes 112 are evenly distributed on the first frame mounting surface 114. The photovoltaic tile 100 is fixedly connected to the roof tile purlin 200 through the mounting holes 112 on the first frame mounting surface 114.

[0039] In this embodiment, the edge of the frame of the photovoltaic component that is snapped on the upper part of the first frame 110 has a flash buckle 111, which forms an interlocking structure with the lower part of the second frame 120 of the adjacent photovoltaic tile 100, which can resist wind-tear, improve the wind resistance of the photovoltaic tile, and also has a waterproof function.

[0040] Among them, in this embodiment, there is an angle between the first frame mounting surface 114 and the first frame lower surface 113, 60 degrees < angle < 90 degrees, and they are not in a vertical relationship. This is because a certain inclination angle is required during the actual installation process to meet the matching relationship between the photovoltaic tiles on the sloping roof.

[0041] Among them, in this embodiment, the first frame mounting surface 114 plays the role of fixing the entire photovoltaic tile, so the thickness will be increased to ensure the required installation strength, and reinforcing ribs are provided at the angle formed by the first frame mounting surface 114 and the first frame lower surface 113 to enhance the strength and rigidity and reduce the damage caused by stress concentration.

[0042] like Figure 4 As shown, in this embodiment, the second frame 120 includes a second frame upper surface 121, and the second frame 120 adopts the A-side design of the non-snap photovoltaic module, that is, the second frame upper surface 121 is flush with the upper surface glass of the photovoltaic module, and there is no height difference between the second frame 120 and the photovoltaic module, which is conducive to rainwater washing the photovoltaic tiles and reducing the dust on the surface of the photovoltaic tiles; Figure 5As shown, when the first frame 110 and the second frame 120 are overlapped, the lower part of the second frame 120 is snapped with the burr snap 111 of the frame edge of the photovoltaic component on the upper part of the first frame 110 of the adjacent photovoltaic tile 100 in the first direction D1 and below.

[0043] like Figure 6 As shown, in this embodiment, the third frame 130 is buckled with the adjacent photovoltaic tile 100 or traditional tile in the second direction D2.

[0044] like Figure 7 As shown, in this embodiment, the fourth frame 140 is buckled with the adjacent photovoltaic tile 100 or traditional tile in the second direction D2.

[0045] like Figure 8 As shown, in the second direction D2, the third frame 130 and the fourth frame 140 are respectively buckled with the fourth frame 140 and the third frame 130 of the adjacent photovoltaic tile 100 to form a sub-frame structure buckled left and right and also serve as a water guide trough.

[0046] like Fig. 9 , 10 As shown in FIG. 11 and FIG. 12 , the adjacent photovoltaic tiles 100 are buckled together along the first direction D1. Fig.13 , Fig.14 As shown, when the adjacent photovoltaic tiles 100 are buckled together along the first direction D1, the burr buckle 111 of the first frame 110 is buckled with the second frame 120.

[0047] like Fig.13 As shown, the fin buckle 111 on the upper portion of the first frame 110 is straight. Fig.14 As shown, the burr buckle 111 on the upper part of the first frame 110 is a curved shape with a certain curvature. Of course, when the burr buckle 111 on the upper part of the first frame 110 adopts a curved arc structure, the part of the second frame 120 that contacts it must also present a certain curvature, forming a concave and convex complementary structure therewith.

[0048] In the embodiment of the present application, the third frame 130 and the fourth frame 140 are respectively buckled with the fourth frame 140 and the third frame 130 of the adjacent photovoltaic tile 100, and the formed left and right buckled sub-frame structure can also serve as a water guide trough.

[0049] The third frame 130 or the fourth frame 140 of the photovoltaic tile can be buckled with the traditional tile, and is compatible with the installation method of the traditional tile, so as to be integrated with the traditional roof, thereby improving the integration degree of the photovoltaic tile and the conventional tile.

[0050] The method for quickly installing photovoltaic tiles, during the photovoltaic tile installation process, the first direction D1 is the roof slope direction, the second direction D2 is the roof width direction, and it is characterized by the following steps:

[0051] Step 1: along the first direction D1, with the crystalline silicon cell side of the photovoltaic tile facing the sky, align the fourth frame of the first photovoltaic tile with the edge of the roof, and fix the first photovoltaic tile with the roof tile purlin through the mounting hole on the mounting surface of the first frame; after the second frame of the second photovoltaic tile is snapped with the flash buckle of the frame edge of the upper buckle photovoltaic module of the first frame of the first photovoltaic tile, the mounting hole on the mounting surface of the first frame of the second photovoltaic tile is fixedly connected with the roof tile purlin; all photovoltaic tiles are installed in sequence along this direction;

[0052] Step 2: Install the adjacent photovoltaic tiles along the second direction D2 to the first photovoltaic tile installed in step 1. The adjacent photovoltaic tiles form a left-right buckled structure that cooperates with the first photovoltaic tile along this direction. Buckle the fourth frame of the adjacent photovoltaic tile to the third frame of the first photovoltaic tile. Then fix the mounting holes on the mounting surface of the first frame of the adjacent photovoltaic tile to the roof tile purlin. Install the photovoltaic tiles in this direction along the first direction D1 in sequence. Install them in the same way until the entire roof is installed.
