[0016] Compared with the existing technology, this photovoltaic curtain wall inner cavity wiring structure has the following beneficial effects:

[0017] 1. The photovoltaic curtain wall utilizes profiled panels with external covers. The inner and outer column profiles, when connected, form a trough-like space. This aluminum alloy profile allows for cabling to occur within the cavity. The horizontal and vertical spacing between the curtain wall columns can be expanded as needed to meet standard cable routing requirements. Larger gaps reduce the heat generated by the photovoltaic cables during power transmission. Ventilation and dust removal components also provide heat dissipation and dust removal, minimizing power loss during power transmission through the photovoltaic curtain wall.

[0018] 2. According to the specific distribution of the curtain wall and electrical appliances, the connection method and connection port of the circuit can be changed to suit different circuit environments. The cable is connected to the terminal blocks on both sides of the outer profile plate of the column, which can be connected in series with the crystalline silicon solar panels on both sides. The curtain wall column set as the main port position can connect the cable to the terminal blocks on the inner profile plate of the column to supply power to the electrical appliances. The wiring design of different branches in the inner chamber can be realized by coordinating the winding column bolts. The cable is pressed against the winding column bolts to provide tension for the cable. In subsequent use, ventilation and heat reduction can be achieved, and the heat of the wiring cable can be reduced, eliminating the risk of short circuit and spontaneous combustion of the circuit system. At the same time, the internal cables are arranged neatly and not easily deformed, avoiding the problem of cables entangled with each other. At the same time, the winding column bolts also fix the cover plate to 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 cables.

[0019] 3. The wind direction caused by the rotation of the fan blades can guide the dust and moisture in the inner cavity to the outside in time, ensuring that the cables are in a normal temperature, dry and low-dust working environment. The curtain wall columns in the middle position are equipped with sealing strips at the joints of their through pipes to ensure the sealing between multiple through pipes. The through pipes at the top and bottom ends will leave a small hole as shown in the figure to discharge the gas inside the through pipe, ensuring the stable operation of the cooling cycle process in the interior space of the curtain wall. When the column outer cover profile plate, column inner profile plate and column outer profile plate are connected, thermal insulation pads are used. Specifically, they can be set as nylon pads, which have thermal insulation effect to ensure that external heat cannot be transmitted into the room through the curtain wall frame.

[0020] Other advantages, objects and features of the present invention will be described in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the invention.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] See also Figures 1 to 15 The present invention provides the following implementation scheme: a photovoltaic curtain wall cavity wiring structure, including a plurality of curtain wall columns 5, each of which is equipped with a crystalline silicon solar panel 6, an outer cover profile plate 8, a column outer profile plate 9 and a column inner profile plate 10 arranged on the outer cover profile plate 8, an H-shaped column component 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 component 14 is located in the middle of the column outer profile plate 9, the outer wall of the H-shaped column component 14 and the inner wall of the column outer profile plate 9 and the inner wall of the column inner profile plate 10 form two wiring cavities, the H-shaped column component 1 4 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 junction box 2 is fixed between the two curtain wall columns 5 and the outer cover profile plate 8. A wiring component 3 is provided in the side junction box 2 to connect the cables of the crystalline silicon solar panel 6 to the corresponding wiring inner cavity. The upper and lower ends of the column outer profile plate 9 and the column inner profile plate 10 are connected with a cover plate 1, and a winding column bolt 7 is fixed between the two cover plates 1. The side wall of the column outer profile plate 9 away from the H-shaped column component 14 and the end wall close to the column inner profile plate 10 are installed with terminal blocks 11. The cable cooperates with the winding column bolt 7 to connect to the corresponding terminal 11.

[0040] 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 thermal insulation pad 15. During installation, the thermal insulation pad 15 can specifically be a silicone-based thermal insulation pad, which has high compressibility and is suitable for various environments. At the same time, it has a high elastic modulus and can effectively absorb the vibration of the equipment, which is suitable for the installation environment of the curtain wall.

[0041] The tail end of the H-shaped column member 14 has a horizontal plate 18, and there is a gap between the horizontal 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 horizontal plate 18 and the outer cover profile plate 8. During installation, the specific model of the foam strip 16 can be a polyethylene foam strip, which has the characteristics of waterproof and moisture-proof and is suitable for the environment of curtain wall installation.

[0042] 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 set in an L-shape, with one side wall close to the H-shaped column member 14 and 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 set in the filling seam 17 to seal the connection between the column outer profile plate 9 and the curtain wall column 5. The provided sealing strip ensures the sealing between the inner cavities, and the heat will only flow out through the through pipe 401. An electric valve can be set at the small hole to close the small hole on rainy days to prevent rainwater from penetrating and causing adverse effects on the circuit.

[0043] Several first bolts 13 are provided between the two sub-frame profile plates 12 to secure the two sub-frame profile plates 12 to the H-shaped column member 14. The bolts are designed to be removable, allowing the outer cover plate 8, column inner profile plate 10, and column outer profile plate 9 to be installed. After confirming that they are correct, the cables can be connected in the exposed space and the cover plate can be installed after the cables are secured. Furthermore, if there is a problem with the curtain wall circuit, the outer gusset plate can be disassembled for maintenance, making it very convenient.

[0044] 407, and the two fan blades 407 are connected to each other by the through-tube 401. A worm gear 403 is fixed on the fan blade 407, and a worm gear 403 is fixed on the transmission shaft 408. A first sealing cover plate 404 is provided 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 provided 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, thereby isolating the problem of mutual influence caused by different temperatures between different inner chambers. The first sealing cover plate 404 is transferred to the sub-frame profile plate 12, and a worm 405 is provided 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, better realizing the circulating airflow for heat dissipation.

[0045] In this embodiment, a plurality of guide plates 409 are installed inside the through pipe 401. Each guide plate 409 is tilted and arranged inside the through pipe 401. A sealing strip 411 is provided 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.

[0046] In this embodiment, the wiring component 3 includes a junction box 302, and adjacent two sides of the junction box 302 are provided with cable holes for passing the cables. A junction box 302 is provided on the cable 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 through the junction box 302, and the staff manually moves the connecting rod 301 to move the junction box 302 between the two corresponding cable holes, which plays a role in wiring. The junction box 302 includes a left frame 303 and a right frame Frame 304, the left frame 303 and the right frame 304 are slidingly 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 cooperate with the elastic force of the spring 305 to stably clamp the cable, and cooperate with the winding column bolt 7 to maintain the tension of the cable, so that the internal cable is neatly arranged and not easy to deform.

[0047] Working Principle: The photovoltaic curtain wall utilizes a trough-like space formed by connecting the outer cover profile 8, the column inner profile 10, and the column outer profile 9. This space allows for cabling to be routed through the aluminum alloy profile structure. The curtain wall's horizontal and vertical clearances can be expanded as needed to meet standard cable routing requirements. Larger clearances reduce the heat generated by the photovoltaic cables during power transmission. The ventilation and dust removal components 4 also provide heat dissipation and dust removal, minimizing power loss during power transmission through the photovoltaic curtain wall.

[0048] When the column outer cover profile plate 8, the column inner profile plate 10 and the column outer profile plate 9 are connected, an insulating pad 15 is used, which can be specifically set to a nylon pad, which has a heat insulation effect and ensures that external heat cannot be transmitted into the room through the curtain wall frame.

[0049] When routing the photovoltaic curtain wall cables of the present invention, the DC cables of the crystalline silicon solar panels 6 pass through the routing components 3 from the slots on the sub-frame profile to the cable cavity. In the cavity, the cable terminals are connected to the other poles of the same cable terminals of another photovoltaic module. This is analogous to forming a battery string. The cables after the modules are connected in series can be connected to the external circuit bus through the gaps in the column cavity. Figure 14 and Figure 15 As shown, according to the specific distribution settings of the curtain wall 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 column outer profile plate 9, which can be connected in series with the crystalline silicon solar panels 6 on both sides. The curtain wall column is set at the total port position, and the cable can be connected to the terminal blocks 11 on the column inner profile plate 10 to supply power to the electrical appliances. The wiring design of different branches in the inner chamber is realized by cooperating with the winding column bolts 7. The cable is pressed against the winding column bolts 7 to provide tension for the cable. In subsequent use, ventilation and heat reduction can be achieved, thereby reducing the heat of the wiring cable and eliminating the risk of short circuit and spontaneous combustion of the circuit system. At the same time, the internal cable is arranged neatly and not easily deformed, thereby avoiding the problem of cables being entangled with each other. At the same time, the winding column bolts 7 also fix the cover plate 1 to the upper and lower ends of the column inner profile plate 10 and the column outer profile plate 9, thereby realizing a closed wiring space inside the curtain wall and reducing the adverse effects of external factors on the cable.

[0050] from Figure 1 It can be seen that a small hole is left on the cover plate 1 for connecting the through pipe 401 on other curtain wall columns. By rotating the fan blade 407, a Figure 14 The wind direction indicated by the arrow, after flowing through the two cable cavities, brings the hot air into the through-tube 401. A guide plate 409 is provided in the through-tube 401, so that the hot air in the through-tube 401 is discharged to the outside in the same direction. The inner wall of the through-tube 401 can be brushed with a thermal insulation coating to block the heat in the through-tube 401 and discharge it to the outside, ensuring the heat dissipation effect of the equipment. Similarly, the wind direction caused by the rotation of the fan blades 407 can guide the dust and moisture in the inner cavity to the outside in time, ensuring that the cable is in a normal temperature, dry and low-dust working environment. The curtain wall column located in the middle position is provided with a sealing strip 411 at the connection of the through-tube 401 to ensure the sealing between multiple through-tubes 401. The through-tube 401 at the top and bottom will be like Figure 1 A small hole is left as shown to discharge the gas inside the through pipe 401 to ensure the stable operation of the cooling cycle process in the interior space of the curtain wall.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
