Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic curtain wall technology, and specifically relates to a photovoltaic curtain wall system. Background Technology

[0002] A photovoltaic (PV) curtain wall is an auxiliary device installed on the exterior wall of a building to absorb solar energy and convert it into electrical energy. It has been widely used in the field of photovoltaic conversion.

[0003] Currently, the installation method for photovoltaic curtain walls typically involves welding the four sides of the curtain wall directly to the wall frame, allowing the curtain wall to fit snugly against the wall. The frame then supports the weight of the curtain wall. However, because the inside of the curtain wall is snugly against the wall, wiring becomes inconvenient, making the installation process time-consuming and laborious for the operator. This method needs further improvement. Utility Model Content

The photovoltaic cable lines can be concealed in the wiring area 5, ensuring the overall appearance and texture of the building, and also facilitating the heat dissipation of the photovoltaic curtain wall components 3. Specifically, a clearance gap 24 is formed between two adjacent aluminum single panels 21, and the sealing member 23 is disposed in the clearance gap 24.

[0028] The fastener 22 includes a fixing angle steel 221 connected to the mounting frame 1 and a fixing screw 222 that fixes the fixing angle steel 221 to the mounting frame 1. Specifically, the fixing angle steel 221 has a U-shaped cross section, and its two ends are respectively connected to two aluminum single panels 21.

[0029] The aluminum panel 21 has an L-shaped cross-section and includes an aluminum panel 211 opposite to the photovoltaic curtain wall component 3 and a connecting plate 212 that is perpendicular to the aluminum panel 211 and connected to the fixing angle steel 221.

The shape of the second connecting portion 342 is adapted to the shape of the second mounting groove 352, making it difficult for the rubber strip 34 to detach from the mounting groove 35. Furthermore, the outer end face of the rubber strip 34 is wavy. The double-glass photovoltaic module 31 is existing technology, and its specific structure and working principle will not be further described here.

The sealant layer 33 can be a double-sided adhesive strip, and its two ends are sealed with silicone structural sealant.

[0033] Reference Figure 6 As shown in the second embodiment of the connecting frame 32 of this application, the connecting frame 32 is suitable for horizontal installation of photovoltaic curtain wall module 3. Its structure is basically the same as that of the connecting frame 32 in the first embodiment. The difference is that the connecting frame 32 also includes a limiting section 323 that extends perpendicularly to the support section 321 to one side of the double-glass photovoltaic module 31. The limiting section 323 and the connecting section 322 are arranged opposite to each other on both sides of the support section 321. Specifically, a double-sided adhesive strip is provided between the limiting section 323 and the opposite side of the double-glass photovoltaic module 31 to realize the connection between the connecting frame 32 and the double-glass photovoltaic module 31.

Specifically, it is set between the double-glass photovoltaic components 31 and the mounting frame 1. It includes a connecting pressure plate 41 connected between the double-glass photovoltaic components 31, a positioning plate 42 set between the connecting pressure plate 41 and the mounting frame 1, and a locking member 43 set between the connecting pressure plate 41 and the positioning plate 42. The connecting pressure plate 41 is located inside the connecting section 322, and its two ends abut against the inner side of the connecting section 322 of the connecting subframe 32 at the ends of the two double-glass photovoltaic components 31, respectively. Specifically, the locking member 43 uses locking screws to connect the connecting pressure plate 41 and the positioning plate 42.

Specifically, the positioning element 47 includes a positioning bolt 471 that passes through the second positioning plate 45 and connects to the third positioning plate 46, and a positioning nut 472 that cooperates with the positioning bolt 471 and abuts against the side of the third positioning plate 46.

[0036] This application defines the structural composition of a photovoltaic curtain wall system. A photovoltaic curtain wall component 3 is installed on the outside of the aluminum single-panel curtain wall structure 2 and connected by a connecting mechanism 4. The connecting mechanism 4 connects the installation frame 1 and the photovoltaic curtain wall component 3 through the clearance gap 24 between the aluminum single panels 21 in the aluminum single-panel curtain wall structure 2, so as to meet the stress requirements for the installation of the photovoltaic curtain wall component 3. A wiring area 5 is formed between the photovoltaic curtain wall component 3 and the aluminum single panel 21 to conceal the photovoltaic cable lines and effectively ensure the overall appearance of the photovoltaic curtain wall system. The overall structure is simple, the stress is reasonable, and it meets the requirements of being detachable, repairable, replaceable, and heat-dissipating.
