Description

TECHNICAL FIELD

[0002] Building Integrated Photovoltaic (BIPV) is a solar photovoltaic power generation system designed, constructed and installed at the same time as the building, and perfectly combined with the building. It is also called "component type" and "building material type" solar photovoltaic building. As a part of the external structure of the building, it has the functions of power generation, building components and building materials, and can enhance the aesthetics of the building and perfectly integrate with the building. As a new building form, BIPV has various application forms, and can be used in photovoltaic tile light surface, daylighting roof, external window sunshade, canopy and a series of scenes, and has great development potential. Among them, as a surface form of photovoltaic building integration, photovoltaic tile can have the basic properties of tiles on the basis of photovoltaic power generation, that is, it can be installed on the roof structure like ordinary roof tiles, and can play the role of waterproof, rainproof, wind resistance and heat preservation.

DETAILED DESCRIPTION

[0047] As can be known from the background, the waterproof performance of the frame overlap position of two photovoltaic tiles in the prior art is poor, and the phenomenon of water leakage and water accumulation is likely to occur, thereby affecting the service life.

[0048] The photovoltaic frame provided by the embodiments of the present disclosure covers the abutting gap between the second connecting structure and the inner wall of the first clamping groove by setting a waterproof strip, so as to avoid liquid from seeping to the back of the photovoltaic tile. Moreover, the first clamping groove is an open upward through groove. If a small amount of liquid still seeps in through the abutting gap, the second structure part plays a flow guiding role on the seepage liquid, and guides the rainwater to the first clamping groove. The first clamping groove further guides the rainwater out, thereby avoiding the phenomenon of water accumulation.

The first frame 100 is clamped on the mounting structure 300 to fix the two photovoltaic tiles 20 on the roof 30.

[0062] Referring to Figure 2 the drawings, Figure 2 A structure schematic diagram of a photovoltaic frame is shown. The first frame 100 includes a first main body 101 arranged opposite to the outer edge side wall of the photovoltaic tile 20, and a first connecting structure 120 and a first clamping structure arranged on both sides of the first main body 101. The first clamping structure includes a pair of opposite and parallel first clamping parts 110 extending from one side of the first main body 101. The pair of first clamping parts 110 and the first main body 101 form a first clamping groove 1101. The photovoltaic tile 20 has opposite first and second surfaces in the height direction Y. When the edge of the photovoltaic tile 20 is accommodated in the first clamping groove 1101, the first clamping part 110 arranged on the upper side abuts against the first surface of the photovoltaic tile 20, the first clamping part 110 arranged on the lower side abuts against the second surface of the photovoltaic tile 20, and the side of the first main body 101 facing the photovoltaic tile 20 abuts against the outer edge side wall of the photovoltaic tile 20, so that the first frame 100 can be clamped on the edge of the photovoltaic tile 20.

[0064] In combination with Figure 3 as shown, Figure 3 A structure diagram of a first frame in a photovoltaic frame is shown, and the first connecting structure 120 is arranged on the side of the first main body 101 away from the first clamping part 110. The first connecting structure 120 includes a first groove wall 122 and a first groove bottom 121 arranged on the side of the first main body 101 away from the first clamping part 110. The first groove wall 122 is arranged in parallel with the first main body 101 and has a certain distance therebetween, and the first groove bottom 121 extends in the width direction X. One end of the first groove bottom 121 is connected with the first main body 101, and the other end is connected with one end of the first groove wall 122 in the height direction Y close to the roof 30, so as to form a first clamping groove 1201 with the first main body 101, the first groove bottom 121 and the second groove wall 222. It should be noted that the drawings of the embodiments of the present disclosure are all sectional views, and the first clamping groove 1201 is a strip-shaped groove structure extending in the length direction Z. The first clamping groove 1201 has a water outlet at both ends in the length direction Z. The internal space of the first clamping groove 1201 has the function of temporarily storing liquid. Since the first clamping groove 1201 is a strip-shaped groove structure, the liquid in the first clamping groove 1201 will be guided to both ends in the length direction Z until it is discharged from the water outlet. The arrangement of the first clamping groove 1201 avoids liquid leakage to the back space of the photovoltaic tile 20 and has a flow guiding effect, improves the water leakage and water accumulation performance of the embodiments of the present disclosure, and improves the service life of the product.

[0065] The first frame 100 further includes a waterproof strip 140 arranged on the same side of the first main body 101 and the first clamping groove 1201. The waterproof strip 140 extends in the width direction X, and the waterproof strip 140 is arranged at a position opposite to the opening of the first clamping groove 1201.

[0066] In combination with Figure 4 as shown, Figure 4A structure diagram of a second frame in a photovoltaic frame is shown, the second connecting structure 220 is arranged on the side of the second main body 201 away from the second clamping part 210, and the second connecting structure 220 includes a second groove wall 222 and a second groove bottom 221 arranged on the side of the second main body 201 away from the second clamping part 210. The second groove wall 222 is arranged in parallel with the second main body 201, and a certain distance is provided therebetween. The second groove bottom 221 extends along the width direction X. One end of the second groove bottom 221 is connected with the main body, and the other end is connected with one end of the second groove wall 222 in the height direction Y away from the roof 30, so that the second main body 201, the second groove bottom 221 and the second groove wall 222 are arranged to form a second clamping groove 2201 with an opening downward.

[0067] In the case where the first connecting structure and the second connecting structure 220 are connected, the second groove bottom 221 and the first groove bottom 121 are arranged in parallel, the second groove wall 222 extends to the first clamping groove 1201 in the opposite direction of the height direction Y, the first groove wall 122 extends to the second clamping groove 2201 in the height direction Y, the second groove wall 222 abuts against the first main body 101 (i.e. one side inner wall of the first clamping groove 1201), and the first groove wall 122 abuts against the second main body 201 (i.e. one side inner wall of the second clamping groove 2201). The first main body 101, the first groove bottom 121, the first groove wall 122, the second main body 201, the second groove bottom 221 and the second groove wall 222 form a containing cavity. The containing cavity is composed of the internal space of the first clamping groove 1201 and the second clamping groove 2201, and the spaces of the first clamping groove 1201 and the second clamping groove 2201 in the containing cavity overlap. The second groove wall 222 abuts against the first main body 101, and a abutting gap is provided therebetween. One end of the abutting gap in the height direction Y is in communication with the first clamping groove 1201 (or the containing cavity), and the other end is in communication with the front space of the photovoltaic tile 20. The waterproof strip 140 is arranged on the side of the second groove bottom 221 in the second connecting structure 220 away from the first groove bottom 121, and the waterproof strip 140 abuts against the surface of the second groove bottom 221 away from the first groove bottom 121, so that the waterproof strip 140 covers one end of the abutting gap in the height direction Y towards the front space of the photovoltaic tile 20, to avoid that the liquid (such as rainwater, cleaning liquid, etc.) falling from the front space of the photovoltaic tile 20 onto the surface of the photovoltaic frame can directly penetrate into the containing cavity between the first connecting structure 120 and the second connecting structure 220 through the abutting gap, thereby improving the water leakage prevention capability of the photovoltaic frame. The second groove bottom 221 and the second groove wall 222 are connected, and the second groove wall 222 extends into the first clamping groove 1201. In the case where liquid seeps onto the surface of the second groove bottom 221, the second groove bottom 221 and the second groove wall 222 have a flow guiding effect, guiding the liquid into the first clamping groove 1201, and then discharging the liquid through the water outlets at both ends of the first clamping groove 1201 in the length direction Z, thereby improving the water accumulation prevention capability of the photovoltaic frame.

[0068] It should be noted that one end of the waterproof strip 140 in the width direction X extends to the second body 201 and abuts against the second body 201, and a first gap is formed between the waterproof strip 140 and the second body 201, and a second gap is formed between the waterproof strip 140 and the second groove bottom 221, further avoiding liquid from leaking from the position of the first gap to the second gap and the abutting gap in turn.
