Description

Technical Field

[0001] The utility model belongs to the field of solar photovoltaic power generation and relates to a photovoltaic tile. Background Art

[0002] BIPV is the main technical route for photovoltaic buildings. As a type of BIPV, photovoltaic tiles have both architectural and power generation functions, and have attracted widespread attention since their launch. The photovoltaic tiles laid on the roof must have a reasonable force-bearing 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 utility model is to provide a photovoltaic tile to address the problems of low installation efficiency and weak wind resistance and wind-tightening resistance of existing photovoltaic tiles due to structural limitations. The problem of surface dust accumulation is similar to that of other photovoltaic solar panels. The photovoltaic tile of the utility model is matched with mainstream solar cells to achieve higher power generation efficiency. It adopts an upper and lower overlap structure to achieve rapid installation and can be laid on the entire roof. It has a stable structure, excellent mechanical properties, and can resist wind resistance and wind-tightening. At the same time, the lower frame of the photovoltaic tile of the utility model 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 utility model is:

[0006] A kind of photovoltaic tile, comprising a photovoltaic module and four side frames. The photovoltaic module is embedded within the four side frames. The four side frames are respectively a first side frame, a second side frame, a third side frame, and a fourth side frame. During 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 opposite first and second side frames along the first direction D1, and has opposite third and fourth side frames along the second direction D2; characterized in that: the first side frame includes a flanging buckle, a lower surface of the first side frame, and a mounting surface of the first side frame. A number of equally spaced mounting holes are evenly distributed on the mounting surface of the first side frame. The photovoltaic tile is fixedly connected to the roof batten through the mounting holes on the mounting surface of the first side frame; a flanging buckle is provided at the upper part of the first side frame, which buckles the edge of the frame of the photovoltaic module, and forms an interlocking structure with the lower part of the second side frame of the adjacent photovoltaic tile, which can resist wind uplift, improve the wind resistance of the photovoltaic tile, and at the same time has a waterproof function. The mounting surface of the first side frame is closely attached to the roof batten, which can realize the rapid positioning and installation of the photovoltaic roof. The equally spaced mounting holes are evenly distributed on the mounting surface of the first side frame and are used to fix the photovoltaic tile on the roof batten.

[0007] An angle is formed between the mounting surface of the first side frame and the lower surface of the first side frame, where 60 degrees < angle < 90 degrees. The mounting surface of the first side frame and the lower surface of the first side frame are not perpendicular to each other because a certain inclination angle is required during the actual installation process to meet the mating relationship of the photovoltaic tile on the sloping roof.

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

[0009] The second side frame includes an upper surface of the second side frame. The second side frame adopts a design of surface A of the photovoltaic module without a buckle, that is, the upper surface of the second side frame is flush with the glass on the upper surface of the photovoltaic module.

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

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

[0012] When the first side frame and the second side frame are lapped, the lower part of the second side frame is clamped with the flanging buckle at the upper part of the edge of the frame of the photovoltaic module of the first side frame of the adjacent photovoltaic tile in the first direction D1 and below.

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

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

[0015] In the embodiment of the present application, the new type of photovoltaic tile further includes a third frame and a fourth frame. The third frame and the fourth frame are respectively connected to the fourth frame and the third frame of adjacent photovoltaic tiles by left-right buckling, and the formed left-right buckling sub-frame structure can also function as a water guide groove at the same time.

[0016] Either the third frame or the fourth frame of the photovoltaic tile can be buckled with a traditional tile, which is compatible with the installation method of the traditional tile, realizes the integration with the traditional roof surface, and improves the integration degree of the photovoltaic tile and the conventional tile.

[0017] A rapid installation method for photovoltaic tiles. During the installation process of the photovoltaic tiles, the first direction D1 is the roof slope direction, and the second direction D2 is the roof width direction. 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 roof edge, and fix and connect the first photovoltaic tile to the roof tile purlin through the installation holes on the installation surface of the first frame; after the second frame of the second photovoltaic tile is snapped with the flash edge buckle on the upper part of the first frame of the first photovoltaic tile at the edge of the photovoltaic module frame, then fix and connect the installation holes on the installation surface of the first frame of the second photovoltaic tile to the roof tile purlin; install all the photovoltaic tiles in sequence along this direction;

[0019] Step 2: Install adjacent photovoltaic tiles along the second direction D2 on the first photovoltaic tile installed in Step 1. The adjacent photovoltaic tiles form a mutually cooperating left-right buckling structure with the first photovoltaic tile along this direction. Buckle the fourth frame of the adjacent photovoltaic tile on the third frame of the first photovoltaic tile, and then fix and connect the installation holes on the installation surface of the first frame of the adjacent photovoltaic tile to the roof tile purlin; install the photovoltaic tiles in sequence along the first direction D1 for this direction; install in the same way in sequence until the entire roof is installed.

[0020] The photovoltaic tile of the present utility model is paired with a mainstream battery cell to achieve a higher power generation efficiency. It adopts an upper and lower overlapping structure to realize rapid installation, full roof paving, stable structure, excellent mechanical properties, and can prevent wind and resist wind uplift. At the same time, the lower frame of the non-dust-accumulating photovoltaic tile of the present utility model adopts a non-A surface design, which can meet the load requirements and achieve the effect of non-dust accumulation by using rainwater flushing. In addition, the photovoltaic tile adopts a left-right buckling design in the structural design, making it have a drainage function at the same time. Description of the Drawings

Specific embodiments

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

[0037] As Figure 1 、 Figure 2 shown, a kind of photovoltaic tile 100 of the present utility model 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 process 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 opposite first frame 110 and second frame 120 along the first direction D1, and has opposite third frame 130 and fourth frame 140 along the second direction D2.

[0038] As Figure 3 shown, in the embodiment of the present utility model, the first frame 110 includes a flange buckle 111, a lower surface 113 of the first frame, and a mounting surface 114 of the first frame. A number of equally spaced mounting holes 112 are evenly distributed on the mounting surface 114 of the first frame. The photovoltaic tile 100 is fixedly connected to the roof batten 200 through the mounting holes 112 on the mounting surface 114 of the first frame;

[0039] In this embodiment, the upper part of the first frame 110 that buckles the edge of the photovoltaic module is provided with a flange buckle 111, which forms an interlocking structure with the lower part of the second frame 120 of the adjacent photovoltaic tile 100, can resist wind uplift, improve the wind resistance of the photovoltaic tile, and has a waterproof function at the same time.

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

[0041] Among them, in this embodiment, the mounting surface 114 of the first frame functions 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 between the mounting surface 114 of the first frame and the lower surface 113 of the first frame to enhance the strength and rigidity and reduce the damage caused by stress concentration.

[0042] As Figure 4As shown, in this embodiment, the second frame 120 includes an upper surface 121 of the second frame. The second frame 120 adopts the A-side design of a snapless photovoltaic module, that is, the upper surface 121 of the second frame is flush with the upper surface glass of the photovoltaic module. There is no height difference between the second frame 120 and the photovoltaic module, which is beneficial for rainwater to wash the photovoltaic tiles and reduce the dust accumulation on the surface of the photovoltaic tiles. As Figure 5 shown, when the first frame 110 and the second frame 120 are lapped, the lower part of the second frame 120 is snap-connected to the upper part of the first frame 110 of the adjacent photovoltaic tile 100 in the first direction D1 and below by a flash snap 111 at the edge of the frame of the photovoltaic module.

[0043] As Figure 6 shown, in this embodiment, the third frame 130 is snap-connected to the adjacent photovoltaic tile 100 or traditional tile in the second direction D2.

[0044] As Figure 7 shown, in this embodiment, the fourth frame 140 is snap-connected to the adjacent photovoltaic tile 100 or traditional tile in the second direction D2.

[0045] As Figure 8 shown, in the second direction D2, the third frame 130 and the fourth frame 140 are respectively snap-connected to the fourth frame 140 and the third frame 130 of the adjacent photovoltaic tile 100 in a left-right snap connection manner, forming a left-right snap-connected sub-frame structure and also serving as a water guide trough function.

[0046] As Figure 9 、 10 、11, 12 shown, the adjacent photovoltaic tiles 100 are snap-connected along the first direction D1. As Figure 13 、 Figure 14 shown, when the adjacent photovoltaic tiles 100 are snap-connected along the first direction D1, the flash snap 111 of the first frame 110 is snap-connected to the second frame 120.

[0047] As Figure 13 shown, the flash snap 111 on the upper part of the first frame 110 is straight. As Figure 14 shown, the flash snap 111 on the upper part of the first frame 110 is in a curved shape with a certain arc. Of course, when the flash snap 111 on the upper part of the first frame 110 adopts a curved arc-shaped structure, the part of the second frame 120 in contact with it also needs to present a certain arc, forming a concave-convex complementary structure.

[0048] In the embodiment of the present application, the third frame 130 and the fourth frame 140 are respectively snap-connected to the fourth frame 140 and the third frame 130 of the adjacent photovoltaic tile 100 in a left-right snap connection manner, and the formed left-right snap-connected sub-frame structure also serves as a water guide trough function.

[0049] Either the third frame 130 or the fourth frame 140 of the photovoltaic tile can be snap-connected to a traditional tile, which is compatible with the installation method of traditional tiles, enabling integration with a traditional roof surface and improving the integration of the photovoltaic tile with conventional tiles.

[0050] A rapid installation method for photovoltaic tiles. During the installation of photovoltaic tiles, the first direction D1 is the roof slope direction, and the second direction D2 is the roof width direction. The method is characterized by the following steps:

[0051] Step 1: Along the first direction D1, with the side of the photovoltaic tile having crystalline silicon cells facing the sky, align the fourth frame of the first photovoltaic tile with the roof edge, and fixedly connect the first photovoltaic tile to the roof batten through the mounting holes on the first frame mounting surface; after the second frame of the second photovoltaic tile is snap-connected to the upper part of the first frame of the first photovoltaic tile through the flanging snap of the edge of the photovoltaic module frame, then fixedly connect the mounting holes on the first frame mounting surface of the second photovoltaic tile to the roof batten; install all the photovoltaic tiles in sequence along this direction;

[0052] Step 2: Install adjacent photovoltaic tiles along the second direction D2 on the first photovoltaic tile installed in Step 1. The adjacent photovoltaic tiles form a mutually cooperating left-right snap-connection structure with the first photovoltaic tile along this direction. Snap the fourth frame of the adjacent photovoltaic tile onto the third frame of the first photovoltaic tile, and then fixedly connect the mounting holes on the first frame mounting surface of the adjacent photovoltaic tile to the roof batten; install the photovoltaic tiles in sequence along the first direction D1 for this direction; install in the same way in sequence until the entire roof is installed.
