[0008] Preferably, a sub-frame profile plate is installed at the connection between the H-shaped column member and the curtain wall column. The sub-frame profile plate is L-shaped. One side wall is closely attached to the H-shaped column member, and there is a gap between the other side wall and the curtain wall column, which is set as a filling seam. A sealing rubber strip is arranged in the filling seam to seal the connection between the column outer profile plate and the curtain wall column; Several first bolts are arranged between the two sub-frame profile plates to fix the two sub-frame profile plates and the H-shaped column member.

[0014] Compared with the prior art, the inner cavity wiring structure of the photovoltaic curtain wall has the following beneficial effects: First, the photovoltaic curtain wall adopts an outer cover profile plate. When the inner profile plate of the column and the outer profile plate of the column are connected, a trough-shaped space is formed. The wiring is carried out by using the cavity of the aluminum alloy profile structure. At the same time, the horizontal and vertical space sizes of the curtain wall column can be enlarged according to needs to meet the cable wiring standard requirements. The larger the gap, the better the cooling effect on the heat generated when the photovoltaic cable transmits electricity. At the same time, the ventilation and dust removal component arranged has the technical effect of heat dissipation and dust removal, reducing the power loss during the power generation and transmission of the photovoltaic curtain wall.

[0015] II. According to the specific distribution settings of the curtain wall and electrical appliances, the connection method and connection ports of the circuit can be changed, which is applicable to different circuit environments. The cable is connected to the terminal blocks on both sides of the outer profile plate of the column, and can be serially processed with the crystalline silicon panels on both sides. The curtain wall column set as the total port position can connect the cable to the terminal block on the inner profile plate of the column to supply power to the electrical appliances. Cooperating with the winding column bolt to realize the wiring design of different branch circuits in the inner cavity. Pressing the cable tightly against the winding column bolt can provide tension for the cable. During subsequent use, it can ventilate and cool down, reduce the heat generated by the energized wiring cable, eliminate the risk of short circuit and spontaneous combustion in the circuit system; at the same time, it also makes the internal cable layout neat, not easily deformed, and avoids the problem of mutual entanglement between cables. At the same time, the winding column bolt also fixes the cover plate at the upper and lower ends of the inner profile plate and the outer profile plate of the column, realizing a closed wiring space inside the curtain wall and reducing the adverse effects of external factors on the cable.

[0016] III. The wind direction caused by the rotation of the fan blades can timely guide the dust and moisture in the inner cavity to the outside, ensuring that the cable is in a working environment of normal temperature, dryness and low dust. At the connection of the through pipes of the curtain wall column in the middle position, sealing strips are provided to ensure the sealing between multiple through pipes. The through pipes at the top and bottom will leave small holes as shown in the figure for discharging the gas inside the through pipes, ensuring the stable operation of the cooling circulation process of the internal space of the curtain wall. When the outer cover profile plate of the column, the inner profile plate of the column and the outer profile plate of the column are connected, heat insulation pads are used, which can be specifically set as nylon pads, having a heat insulation effect to ensure that external heat cannot be transmitted into the room through the curtain wall skeleton.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 15, the present invention provides the following embodiments: A photovoltaic curtain wall internal wiring structure includes several curtain wall columns 5, each of which is installed with a crystalline silicon solar panel 6.

An H-shaped column member 14 is integrally provided on the end wall of the column inner profile plate 10 close to the column outer profile plate 9. The H-shaped column member 14 is located in the middle of the column outer profile plate 9. Two wire arranging inner cavities are formed between the outer wall of the H-shaped column member 14 and the inner walls of the column outer profile plate 9 and the column inner profile plate 10. The internal closed area of the H-shaped column member 14 is set as a ventilation and dust removal inner cavity, and a ventilation and dust removal component 4 is installed in the ventilation and dust removal inner cavity. A side connection box 2 is fixed between the two curtain wall columns 5 and the outer cover profile plate 8. A wiring component 3 is arranged in the side connection box 2 to lead the cables of the crystalline silicon solar panel 6 into the corresponding wire arranging inner cavities. Cover plates 1 are connected to the upper and lower ends of the column outer profile plate 9 and the column inner profile plate 10. A winding column bolt 7 is fixed between the two cover plates 1. Wiring terminals 11 are installed on the side wall of the column outer profile plate 9 far from the H-shaped column member 14 and on the end wall close to the column inner profile plate 10. The cables cooperate with the winding column bolt 7 to connect to the corresponding wiring terminals 11.

[0022] In this embodiment, there is a gap between the curtain wall column 5 and the outer cover profile plate 8, and the gap is filled with a heat insulation spacer 15. During installation, the heat insulation spacer 15 can specifically adopt a silicone-based heat insulation spacer, which has high compressibility, is suitable for various environments, and has the characteristic of high elastic modulus, and can effectively absorb the vibration of the equipment and adapt to the installation environment of the curtain wall. The tail end of the H-shaped column member 14 has a cross plate 18. There is a gap between the cross plate 18 and the outer cover profile plate 8, and the gap is filled with a foam strip 16. Several second bolts 19 are fixed between the cross plate 18 and the outer cover profile plate 8. During installation, the specific model of the foam strip 16 can adopt a polyethylene foam strip, and its characteristics of waterproof and moisture-proof are suitable for the installation environment of the curtain wall.

[0023] In this embodiment, a sub-frame profile plate 12 is installed at the connection between the H-shaped column member 14 and the curtain wall column 5. The sub-frame profile plate 12 is L-shaped. One side wall is closely attached to the H-shaped column member 14, and there is a gap between the other side wall and the curtain wall column 5, which is set as a filling seam 17. A sealing strip is arranged in the filling seam 17 to seal the connection between the column outer profile plate 9 and the curtain wall column 5. The arranged sealing strip ensures the sealing between the inner cavities, and its heat can only flow out through the through pipe 401. An electric valve can be arranged at the small hole. In rainy days, the small hole is closed to avoid the penetration of rainwater and cause adverse effects on the circuit. A plurality of first bolts 13 are arranged between the two sub-frame profile plates 12 to fix the two sub-frame profile plates 12 and the H-shaped column member 14. Through the detachable design of the bolts, the outer cover profile plate 8, the column inner profile plate 10, and the column outer profile plate 9 can be installed to connect the cables in the exposed space. After confirming that they are correct, the cables are fixed and the cover plate is installed. At the same time, if there is a problem with the curtain wall circuit, the outer buckle plate can be disassembled for maintenance, which is very convenient.

[0024] In the present embodiment, the ventilation and dust removal component 4 comprises a through pipe 401 and two fan blades 407. The two fan blades 407 are respectively arranged on both sides of the H-shaped column component 14. A transmission shaft 408 is fixed between the two fan blades 407. The transmission shaft 408 is rotatably penetrated and arranged on the through pipe 401. A second sealing cover plate 410 is fixed between the through pipe 401 and the side wall of the H-shaped column component 14. Both sides of the H-shaped column component 14 are provided with mounting grooves for mounting the fan blades 407. The through pipe 401 is connected with one of the ventilation and dust removal cavities. The upper and lower ends of the through pipe 401 are connected with the outside. The two sub-frame profile plates 12 and the H-shaped column component 14 are both provided with through holes 1201, so that the two ventilation and dust removal cavities are connected. The two sub-frame profile plates 12 are both installed with fan blade frames 402. The fan blade frames 402 have a protective function to prevent the cable insulation sleeve from aging and becoming loose and contacting the fan blades 407, thereby isolating safety hazards. On the fan blade 407, a worm gear 403 is fixed on the transmission shaft 408, and a first sealing cover plate 404 is arranged on the side of the worm gear 403 close to the sub-frame profile plate 12. The first sealing cover plate 404 and the second sealing cover plate 410 are arranged at the same time, so that the wind direction will only flow out to the outside through the through pipe 401. The moisture in the inner chambers between different curtain walls is stably discharged under the action of the guide plate 409, and the problem of mutual influence between the different temperatures of different inner chambers is isolated. The first sealing cover plate 404 is transferred to the sub-frame profile plate 12, and a worm 405 is arranged at the bottom of the worm gear 403. The worm gear 403 and the worm 405 are meshed with each other. A motor 406 is fixedly installed on the inner wall of the H-shaped column component 14, and the output shaft of the motor 406 is fixed to the end of the worm 405. Through the motor 406, the worm gear 403 and the worm 405 are meshed and rotated, so that the two fan blades 407 rotate synchronously, and the circulating wind flow is better realized for the effect of heat dissipation.

[0025] In this embodiment, a plurality of guide plates 409 are installed inside the through pipe 401. Each guide plate 409 is tiltedly arranged inside the through pipe 401. A sealing strip 411 is arranged at the joint of two through pipes 401. Figure 11 It can be seen that a gap is left between the guide plate 409 and the through pipe 401 for the passage of wind, and the inclined setting can guide the wind direction.

[0026] In this embodiment, the wiring component 3 includes a junction box 302, and the adjacent two sides of the junction box 302 are provided with wiring holes for the cables to pass through. A junction box 302 is arranged on the wiring holes in the same row, and a connecting rod 301 is fixed between each junction box 302. A slide rail 201 is provided on the upper end of the side junction box 2, and a connecting rod 301 is slidably connected to the slide rail 201. The cable is fixed by the junction box 302. The staff manually pushes the connecting rod 301 to move the junction box 302 between the two corresponding wiring holes, which plays a role in wiring. The junction box 302 includes a left frame 303 and a right frame The left frame 303 and the right frame 304 are slidably connected, and a spring 305 is provided at the connection, the inner wall of which is used to clamp the cable, and a cartilage clamp 306 is fixed on the left frame 303, and the cartilage clamp 306 is made of rubber. The specific material of the cartilage clamp 306 can be set to silicone rubber, which has high elasticity and insulation. When the cable supports the cartilage clamp 306 to deform, the high elasticity of the cartilage clamp 306 itself will always transmit pressure inward, and the elastic force of the spring 305 can stably clamp the cable, and the winding column bolt 7 can maintain the tension of the cable, so that the internal cable is arranged neatly and not easy to deform.

[0027] Working principle: The photovoltaic curtain wall uses a profile plate with an outer cover 8, a column inner profile plate 10, and a column outer profile plate 9 to form a groove space when connected, and uses the aluminum alloy profile structure cavity for routing. At the same time, the horizontal and vertical space size of the curtain wall can be expanded as needed to meet the standard requirements for cable routing. The larger the gap, the heat generated by the photovoltaic cable when transmitting electricity can be cooled. At the same time, the ventilation and dust removal components 4 set up have the technical effect of heat dissipation and dust removal, reducing the power loss during the photovoltaic curtain wall power generation and transmission.

[0028] When the column outer cover profile plate 8, the column inner profile plate 10 and the column outer profile plate 9 are connected, a heat insulating pad 15 is used, which can be specifically set as a nylon pad, which has a heat insulating effect to ensure that external heat cannot be transmitted into the room through the curtain wall frame.

[0029] When the photovoltaic curtain wall cable of the present invention is routed, the DC cable of the crystalline silicon battery panel 6 passes through the routing component 3 from the slot on the sub-frame profile to the wiring cavity, and the cable terminal in the cavity is connected to the other pole of the same cable terminal of another photovoltaic module. And so on to form a battery string. The cable after the module string is connected can be connected to the external circuit bus through the gap in the column cavity. Figure 14 and Figure 15 As shown, according to the specific distribution of curtain walls and electrical appliances, the circuit connection method and connection port can be changed to suit different circuit environments, such as Figure 14As shown, the cable is connected to the terminal blocks 11 on both sides of the outer profile plate 9 of the column, and can be connected in series with the crystalline silicon panels 6 on both sides. The curtain wall column set at the total port position can connect the cable to the terminal blocks 11 on the inner profile plate 10 of the column to supply power to the electrical appliances. In cooperation with the winding column bolt 7, a wire routing design for different branch circuits in the inner cavity is realized. The cable is pressed against the winding column bolt 7, which can provide tension for the cable. During subsequent use, ventilation can reduce heat, lower the heat generated by the energized wire routing cable, and eliminate the risk of short circuit and spontaneous combustion in the circuit system. At the same time, it makes the internal cable routing neat, not easily deformed, and avoids the problem of mutual entanglement between cables. At the same time, the winding column bolt 7 also fixes the cover plate 1 at the upper and lower ends of the inner profile plate 10 and the outer profile plate 9 of the column, realizing a closed wire routing space inside the curtain wall and reducing the adverse effects of external factors on the cable.

[0030] As can be seen from Figure 1 the cover plate 1, there is a small hole provided for connecting to the through pipe 401 on other curtain wall columns. Through the rotation of the fan blade 407, a Figure 14 wind direction indicated by the arrow is formed. After flowing through the two wire routing inner cavities once, the hot air is brought into the through pipe 401. A guide plate 409 is provided in the through pipe 401 to make the hot air in the through pipe 401 be discharged to the outside in the same direction. The inner wall of the through pipe 401 can be coated with a heat insulation layer to block the heat in the through pipe 401 and discharge it to the outside to ensure the heat dissipation effect of the equipment. Similarly, the wind direction caused by the rotation of the fan blade 407 can timely guide the dust and moisture in the inner cavity to the outside, ensuring that the cable is in a normal temperature, dry and low-dust working environment. For the curtain wall column in the middle position, sealing strips 411 are provided at the joints of the through pipes 401 to ensure the sealing between multiple through pipes 401. The through pipes 401 at the top and bottom ends will Figure 1 leave small holes as shown for discharging the gas inside the through pipe 401 to ensure the stable operation of the cooling circulation process of the internal space of the curtain wall.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
