The photovoltaic curtain wall and the photovoltaic module thereof provided by the embodiment of the application are described in detail. A plurality of photovoltaic modules 100 are included on a photovoltaic curtain wall, and the photovoltaic modules 100 are mutually spliced to form the whole photovoltaic curtain wall. Referring to fig. 1, the photovoltaic module 100 includes a photovoltaic panel 1, a frame 2 and a buckle cover 3.

The positions of the threading holes 43 on both sides may be aligned with each other or may be offset from each other, and may be adjusted accordingly according to the actual construction conditions, which is not particularly limited.

The "cross-sectional area of the threading channel 200" can be understood with reference to fig. 3, and the entire circular hole area of the threading hole 3 is within the cross-sectional area of the entire threading channel 200.

In this way, the cable 12 may be threaded into the through-wire channel 200 from the threading hole 43, or threaded out of the frame 2 from the through-wire channel 200 by the threading hole 43, which is beneficial to connecting the cables 12 between adjacent photovoltaic modules 100 in series.

Compared with the prior art, the photovoltaic module 100 provided by the embodiment of the application mainly comprises the photovoltaic panel 1 and the frame 2, and the photovoltaic panel 1 is arranged in the frame 2. The frame 2 is composed of four side frames 4, each side frame 4 on the frame 2 is provided with an upper frame groove 42 and a lower frame groove 42 which are opened inwards, wherein the upper frame groove 41 is used for being embedded and fixed with the photovoltaic panel 1, and the lower frame groove 42 is used as a wire hiding position of the cable 12 on the photovoltaic panel 1. The lower frame groove 42 of the frame 4 is provided with the buckle cover 3, and the buckle cover 3 and the lower frame groove 42 jointly form a wire passing channel 200 for accommodating the cable 12 so as to store the cable 12 on the back of the photovoltaic panel 1 and prevent the cable 12 from being exposed and affecting the appearance.

In addition, the two side frames 4 adjacent to the frame 4 with the buckle cover 3 are respectively provided with threading holes 43, and the projections of the threading holes 43 on the two sides are all positioned in the cross section range of the threading channel 200, so that the cable 12 can be led out of or led into the threading channel 200 from the threading holes 43. The cables 12 between the adjacent photovoltaic modules 100 can mutually penetrate through the wires, which is beneficial to carding the cables 12 on the photovoltaic modules 100.

Compared with the structure that only the frame 4 is used as the wire hiding part in the related art, the photovoltaic module 100 of the application enables the buckle cover 3 and the lower frame groove 42 to enclose to form the tubular wire passing channel 200, so that the wire hiding space can be expanded, the wire 12 can be coated and protected, the damage to the wire 12 caused by the fact that foreign objects or water liquid are easily permeated due to the influence of external environment is avoided, and potential safety hazards are effectively eliminated.

In the embodiment of the present application, referring to fig. 4, the frame 4 has an upper transverse plate 44, a middle transverse plate 45 and a lower transverse plate 46 extending in parallel to the inner side of the frame 2, the upper transverse plate 44 and the middle transverse plate 45 are disposed at intervals to form an upper frame slot 41, and the middle transverse plate 45 and the lower transverse plate 46 are disposed at intervals to form a lower frame slot 42.

In conjunction with fig. 5, the buckle cover 3 is preferably an open-sided frame, and the buckle cover 3 includes an upper peripheral edge 31, a lower peripheral edge 32, and a connecting plate 33, wherein the connecting plate 33 is integrally connected between the upper peripheral edge 31 and the lower peripheral edge 32. In the installation process, the upper surrounding edge 31 of the buckle cover 3 is in installation connection with the middle transverse plate 45 of the frame 4, and the lower surrounding edge 32 of the buckle cover 3 is in installation connection with the lower transverse plate 46 of the frame 4. As shown in fig. 3, the buckle cover 3 and the lower frame groove 42 are enclosed to form a tubular wire passing channel 200, so as to increase the wire hiding space and effectively accommodate and cover the cable 12 on the photovoltaic panel 1.

In one embodiment of the present application, referring to fig. 4 and 5, the edge of the middle transverse plate 45 is provided with a buckling rib 451 protruding downwards, and the edge of the lower transverse plate 46 is provided with a buckling groove 461. The upper peripheral edge 31 of the buckle cover 3 is provided with an upper buckle hook 311 which is buckled with the buckle rib 451, and the lower peripheral edge 32 of the buckle cover 3 is provided with a lower buckle hook 321 which is buckled with the buckle groove 461. Thus, the fastening and fixing of the upper and lower connection parts are realized, and the pipe-shaped wire passing channel 200 is formed by enclosing. In addition, the fastening cover 3 and the lower frame groove 42 of the frame 4 are connected in a mutually fastening manner, so that the structure is simple, the implementation is easy, a perforation fixing manner of fasteners such as dew threads is not needed, and the assembly and disassembly efficiency is effectively improved.

In the embodiment of the present application, referring to fig. 5, 6 and 7, the extension length L1 of the middle transverse plate 45 of the frame 4 is smaller than the extension length L2 of the lower transverse plate 46, and the width L3 of the upper peripheral edge 31 of the buckle cover 3 is larger than the width L4 of the lower peripheral edge 32.

As shown in fig. 5, the upper peripheral edge 31 further has an arc-shaped abutting portion 312 connected to the upper clasp 311, and the arc-shaped abutting portion 312 abuts against an end portion of the middle transverse plate 45 to enable the clasp cover 3 to be turned upside down during the assembling and disassembling operation.

As shown in fig. 7, the fastening slot 461 on the frame 4 is opened on the upper surface of the lower transverse plate 46, and the lower hook 321 on the fastening cover 3 is fastened with the fastening slot 461 up and down.

The above-mentioned arrangement on the frame 4 and the buckle cover 3, when the buckle cover 3 is mounted in the lower frame slot 42 of the frame 4, the upper buckle 311 of the buckle cover 3 can be skillfully fastened on the buckle rib 451 of the middle transverse plate 45, and simultaneously the lower buckle 321 is fastened on the buckle slot 461 of the lower transverse plate 46, so as to complete the mounting and fixing. When the buckle cover 3 is detached from the lower frame groove 42 of the frame 4, the lower buckle 321 can be separated from the buckle groove 461 of the lower transverse plate 46, and then the arc-shaped abutting part 312 on the buckle cover 3 and the abutting part of the end part of the middle transverse plate 45 are used as axes, and the upper buckle 311 can be separated from the buckle rib 451 of the middle transverse plate 45 by slightly overturning upwards, so that the detachment operation is completed. Therefore, on the photovoltaic module 100 of the present application, the buckle cover 3 can be easily installed and fixed on the lower frame groove 42 of the frame 4, or detached from the lower frame groove 42, without auxiliary tools, and the structure is simple, and the assembly and disassembly efficiency is effectively improved.

On the basis of the above, when the photovoltaic module 100 is installed, as shown in fig. 2, the photovoltaic panel 1 is installed on the frame 2, and then the cables 12 are arranged, so that the photovoltaic panel 1 is covered above the lower frame groove 42 of the frame 4, and the structure is compact, so that the installation operable space of the buckle cover 3 is limited. It can be seen that, in order to enable the upper clasp 311 of the clasp 3 to be skillfully fastened to the buckling rib 451 of the frame 4, or enable the clasp 3 to be turned upwards slightly when being detached so that the upper clasp 311 can be separated from the buckling rib 451, a certain separation gap M is required between the lower side of the photovoltaic panel 1 and the clasp 3, so that the clasp 3 can have a corresponding movable space.

For this reason, in one embodiment of the present application, referring to fig. 8 and 9, a cushion block 411 for raising the photovoltaic panel 1 is disposed in the upper frame groove 41 of the frame 4, and the cushion block 411 is used to raise the photovoltaic panel 1, so that an isolation gap M is formed between the photovoltaic panel 1 and the buckle cover 3. The isolation gap M is utilized to enable the buckle cover 3 to perform corresponding operation activities in the assembly and disassembly process, so that the buckling fixation of the upper buckle hook 311 and the buckle rib 451 is realized, or the buckle cover 3 is operated to be turned upwards to enable the upper buckle hook 311 to be separated from the buckle rib 451, and the assembly and disassembly operations are smoothly completed.

In another embodiment of the present application, referring to fig. 10, 11 and 12, the fastening rib 451 extends downward from the lower surface of the middle transverse plate 45, and the upper hook 311 on the fastening cover 3 is fastened to the extending end 452 of the fastening rib 451. In this way, the part where the upper clasp 311 of the clasp cover 3 and the clasp rib 451 on the middle transverse plate 45 are buckled with each other is far away from the photovoltaic panel 1, so that an isolation gap M is formed between the photovoltaic panel 1 and the clasp cover 3. The isolation gap M enables the buckle cover 3 to be installed on the frame 4 or detached from the frame 4 smoothly in the process of assembling and disassembling.

It can be seen that, in the photovoltaic module 100 provided in the embodiment of the present application, an isolation gap M for operating and moving the buckle cover 3 in the assembling and disassembling process is provided between the photovoltaic panel 1 and the buckle cover 3, so that the buckle cover 3 can be smoothly mounted on the frame 4 or dismounted from the frame 4.

Because the installation positions of the photovoltaic panel 1 and the buckle cover 3 are very close, the buckle cover 3 is easy to scratch the back surface of the photovoltaic panel 1 in the assembly and disassembly process, and the photovoltaic panel 1 is damaged. In order to avoid the easy damage of the buckle cover 3 to the photovoltaic panel 1 during the assembly and disassembly process, as shown in fig. 9 and 10, the connection part 34 between the upper surrounding edge 31 and the connection plate 33 on the buckle cover 3 is preferably an arc angle, so that the traditional right angle connection is improved to be an arc angle connection, the corner benefiting part is avoided to be formed above the buckle cover 3, the damage to the back surface of the photovoltaic panel 1 is prevented from being easily caused, and the protection effect on the photovoltaic panel 1 is improved.

In the embodiment of the present application, referring to fig. 1 and 13, the frame 2 further includes an angle brace 21, where the angle brace 21 is preferably an L-shaped member and is disposed at the connection between two ends of the adjacent frames 4, so as to improve the structural strength of the frame 2. The threading hole 43 on the frame 4 and the corner code 21 are arranged in an avoiding manner, so that the structure strength of the corner part of the frame 2 is prevented from being influenced by the opening of the corner part of the frame 2.

Preferably, as shown in fig. 14, a drain hole 47 is provided in the frame 4, and the drain hole 47 is provided adjacent to the threading hole 43. Specifically, the drain hole 47 may be formed at the bottom of the lower frame slot 42 of the frame 4, so that the water possibly penetrating from the threading hole 43 can be rapidly removed from the drain hole 47, and the influence on the cable 12 is avoided.

On the photovoltaic curtain wall provided by the embodiment of the application, a plurality of photovoltaic modules 100 are mutually spliced, and the positions of the threading holes 43 on the frames 4 correspond to each other on the adjacent photovoltaic modules 100, so that the cables 12 accommodated on the same side frame 4 of the photovoltaic modules 100 can penetrate through in sequence.

In practical applications, since the frame 2 of the photovoltaic module 100 is generally a metal frame profile, the threading holes 43 formed in the metal frame profile easily form edges, and the edges of the threading holes 43 easily wear the threaded cables 12. If the skin of the cable 12 is damaged, electrical leakage is likely to occur, and even a fire hazard or other safety problem is caused.

In order to improve the protection effect of the cable 12, in an embodiment of the present application, referring to fig. 15 and 16, the photovoltaic modules 100 further include a first protection sleeve 5 for preventing the cable 12 from being worn, where the first protection sleeve 5 is disposed on the threading holes 43 of each photovoltaic module 100. The first protection sleeve 5 is sleeved on the threading hole 43, so that damage to the cable 12 caused by sharp edges on the threading hole 43 is avoided, the cable 12 can pass through and be erected without damage, and the protection effect of the cable 12 is effectively ensured.

Preferably, referring to fig. 17 and 18 together, the first protective sleeve 5 includes a long sleeve 51 and a short sleeve 52, and the long sleeve 51 can be sleeved on the short sleeve 52. In this way, on the adjacent photovoltaic modules 100, the long tube sleeve 51 is provided in the threading hole 43 on one photovoltaic module 100, and the short tube sleeve 52 is provided in the threading hole 43 on the other photovoltaic module 100. When the photovoltaic modules 100 are spliced, the long pipe sleeve 51 is sleeved into the short pipe sleeve 52, so that an isolation gap is avoided between two first protection sleeves 5 installed on the adjacent photovoltaic modules 100, and the sealing effect is effectively improved.

In another embodiment of the present application, referring to fig. 19 and 20, the photovoltaic modules 100 further include a second protection sleeve 6 for preventing the cables 12 from being worn, and two ends of the second protection sleeve 6 are respectively fixed on the threading holes 43 of two adjacent photovoltaic modules 100. With this, two through wires holes 43 on the adjacent photovoltaic module 100 are connected through the both ends of a second protective sheath 6, can enough prevent that sharp limit on the through wires hole 43 from causing the injury to cable 12 easily, can avoid having the seepage clearance between two adjacent through wires holes 43 again, ensure sealed effect effectively.

The first protective sleeve 5 and the second protective sleeve 6 can be rubber rings made of plastic materials, so that the rubber rings can be conveniently installed on the threading holes 43, and the manufacturing cost is effectively reduced.
