[0041] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0042] like Figures 1-3 As shown, a photovoltaic module frame assembly component includes a photovoltaic module 1, a photovoltaic frame 2, and a corner bracket 3.

[0043] Both the photovoltaic frame 2 and the corner bracket 3 are made of conductive materials, and a covering layer of insulating material is provided on the outer surface of both the photovoltaic frame 2 and the corner bracket 3. In this embodiment, both the photovoltaic frame 2 and the corner bracket 3 are made of metal materials, and a covering layer is provided on the outer surface of both the photovoltaic frame 2 and the corner bracket 3. Specifically, both the photovoltaic frame 2 and the corner bracket 3 are made of aluminum materials, and an oxide protective film is provided on the surface of both the photovoltaic frame 2 and the corner bracket 3.

[0044] The photovoltaic module 1 includes two oppositely arranged horizontal sides 11 and two oppositely arranged vertical sides 12.

[0045] A photovoltaic frame 2 is provided on two vertical sides 12 and at least one horizontal side 11.

[0046] The photovoltaic frame 2 includes a plug-in cavity 21 arranged along its axial direction. At least one side wall of the plug-in cavity 21 is provided with a piercing rib 4, which is arranged along the axial direction of the plug-in cavity 21.

[0047] like Figure 1 As shown, the corner code 3 includes two vertically arranged insertion arms 31. The corner code 3 is integrally cast, and the insertion arms 31 have piercing surfaces 32 on their side walls corresponding to the piercing ribs 4.

[0048] Since the surfaces of corner bracket 3 and photovoltaic frame 2 are usually treated with baking paint, spray paint or coloring, or because the corner bracket 3 and photovoltaic frame 2 are made of aluminum material with an oxide protective layer formed on the surface, the surface of corner bracket 3 is in an insulating state. However, under the action of piercing rib 4, when the insertion arm 31 is inserted into the insertion cavity 21, the piercing rib 4 will form a piercing groove 33 on the piercing surface 32, destroying the paint or oxide protective layer of the piercing surface 32, so that the insertion arm 31 and the corresponding two photovoltaic frames 2 form an equipotential body, that is, the two adjacent photovoltaic frames 2 can be connected through the corner bracket 3, so that the photovoltaic module can conduct electricity throughout the watt, thus making it easy to have good safety when only a single point is grounded.

[0049] Otherwise, if the two adjacent corner codes 3 are insulated by the paint surface or the oxidation protective layer, the whole tile conduction of the photovoltaic module cannot be realized. In this case, if single-point grounding is used, there is a situation that the leakage position and the grounding wire are not conductive, which cannot completely guarantee the safety of use and has a large safety hazard.

[0050] As shown in Figure 2 and Figure 3 , the insertion arm 31 is inserted into the insertion cavity 21, and the puncture muscle 4 forms a puncture groove 33 on the puncture surface 32.

[0051] As shown in Figure 1 , the insertion arm 31 is provided with an inclined guide surface 34 on the side wall corresponding to the puncture muscle 4, and the inclined guide surface 34 is located at the end of the insertion arm 31 and connected with the puncture surface 32.

[0052] The insertion arm 31 is provided with a chip removal groove 35 on the side wall corresponding to the puncture muscle 4, the chip removal groove 35 is located on the side opposite to the inclined guide surface 34, and the chip removal groove 35 is lower than the surface of the puncture surface 32. By cutting off the puncture surface 32 with the chip removal groove 35, the resistance of installing the corner code 3 is reduced, and the debris generated by the puncture surface 32 is discharged, avoiding the installation of the corner code 3.

[0053] The insertion cavity 21 is a rectangular structure, the insertion cavity 21 is located below the photovoltaic module 1, and the puncture muscle 4 is arranged on the side wall of the insertion cavity 21 perpendicular to the photovoltaic module 1 and below the photovoltaic module 1.

[0054] The corner code 3 is integrally cast, and the corner code 3 is provided with a weight reduction groove 36.

[0055] The weight reduction groove 36 is provided with a reinforcing rib 37.

[0056] As shown in Figure 2 and Figure 3 , the photovoltaic frame 2 is provided with a glue containing groove 22 at the upper end, and the horizontal edge 11 and the vertical edge 12 are respectively sealedly connected with the glue containing groove 22.

[0057] Specifically, as shown in Figure 2 , the cross section of the glue containing groove 22 on the photovoltaic frame 2 corresponding to the vertical edge 12 is a U-shaped structure, and a glue blocking rib is arranged on the upper side wall of the glue containing groove 22. When the edge part of the photovoltaic module 1 is inserted into the glue containing groove 22, the sealant in the glue containing groove 22 will flow, and the glue blocking rib will hinder the flow of the sealant, preventing the sealant from overflowing.

[0058] As shown in Figure 3 , the cross section of the glue containing groove 22 on the photovoltaic frame 2 corresponding to the horizontal edge 11 is an L-shaped structure, and the edge part of the photovoltaic module 1 is directly lapped in the glue containing groove 22, and the sealant is connected and sealed to the end and the lower surface of the horizontal edge 11.

[0059] As Figures 4-6 shown, a photovoltaic roof, the photovoltaic module 1 is assembled by the photovoltaic module frame assembly component, the horizontal edges 11 of two adjacent photovoltaic modules 1 are overlapped together along the roof slope, and the water guide structure 5 is arranged between the vertical edges 12 of the two adjacent photovoltaic modules 1.

[0060] The photovoltaic cable joints 13 of the two adjacent photovoltaic modules 1 are clamped together, and the photovoltaic cable joints 13 are electrically connected to the photovoltaic module 1 through the photovoltaic cables 14.

[0061] The corner code 3 is grounded through the conductive wire.

[0062] As Figure 6 shown, the photovoltaic roof further comprises a protective sleeve assembly 6, and the protective sleeve assembly 6 comprises a fireproof sleeve 61 and a sleeve sealing cover 62.

[0063] The fireproof sleeve 61 is sleeved on the outer side of the two connected photovoltaic cable joints 13, and the sleeve sealing cover 62 is sleeved on the photovoltaic cable 14 and clamped with the opening of the fireproof sleeve 61.

[0064] The water guide structure 5 comprises a water guide frame 51 and a water drop frame 52, and the water guide frame 51 and the water drop frame 52 are arranged on the photovoltaic frame 2 of the two adjacent vertical edges 12 respectively.

[0065] The water guide frame 51 comprises a support frame 511 and a water guide groove 512 arranged at the upper end of the support frame 511, and the water drop frame 52 comprises a connecting frame 521 and a water drop edge 522 located below the end of the connecting frame 521.

[0066] The connecting frame 521 is located above the water guide groove 512, and the water drop edge 522 is in contact with the side wall of the water guide groove 512. The water drop edge 522 plays a role of guiding water, and the rainwater above the photovoltaic module 1 is introduced into the water guide groove 512, and then flows down the roof quickly under the action of gravity, so as to avoid the accumulation of rainwater above the photovoltaic module 1.
