Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic curtain walls, in particular to a photovoltaic curtain wall wiring structure. Background Art

[0002] The photovoltaic curtain wall on the building is generally composed of multiple photovoltaic wall panels that can absorb light energy. Photovoltaic modules are generally composed of photovoltaic arrays to generate electricity. Power is transmitted between photovoltaic panels through cables. Since photovoltaic wall panels are installed outdoors, in order to ensure the beauty of the wall panels, the cables need to be installed behind the photovoltaic wall panels.

[0003] The wiring scheme for photovoltaic curtain wall cables in the prior art can refer to a photovoltaic curtain wall wiring assembly with application number 201921880148.3. Although the patent hides the cables, all the cables are located in the aluminum alloy beams, and there is no distinction within the aluminum alloy beams, which is relatively messy. It is also necessary to set through holes on the aluminum alloy columns. The through holes will affect the strength of the aluminum alloy columns. After the cables pass through the through holes, the junction box at the cable connection is exposed to the air, and rainwater seeps into the junction box, causing circuit failure. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic curtain wall wiring structure, which can solve the problem of heavy workload in the existing photovoltaic curtain wall installation.

[0005] To achieve the above-mentioned purpose, the utility model proposes a photovoltaic curtain wall wiring structure, comprising a plurality of adjacent photovoltaic panels, an insulation board is provided on the rear side wall of the photovoltaic panels, an installation seam is provided between the photovoltaic panels, a wiring groove is opened through the insulation board, and cables are passed through the wiring groove. The cables on adjacent photovoltaic panels are connected at the installation seam position through a junction box, and the junction box and cables in the installation seam are fixed by sealant.

[0006] It is further configured that the cables at the installation seam are configured to be U-shaped.

[0007] It is further configured that the photovoltaic panel is flush with the side of the insulation panel, and a front glass panel is attached to the front side wall of the photovoltaic panel, and the size of the front glass panel is larger than the photovoltaic panel.

[0008] It is further configured that sealant is provided at a position where the front glass plate is larger than the photovoltaic panel.

[0009] It is further configured that the sealant is simultaneously adhered to the sides of the photovoltaic panel and the insulation board.

[0010] It is further configured that the insulation board is installed on the wall, and the sealant is simultaneously pasted between the glass board and the wall.

[0011] It is further configured that the cross-section of the wiring trough is rectangular and the spacing between the wiring troughs is greater than the cable diameter.

[0012] It is further configured that the wiring trough is arranged close to the bottom end of the photovoltaic panel.

[0013] It is further configured that the photovoltaic panels are evenly arranged in the transverse direction and the photovoltaic panels are spaced apart in the transverse direction.

[0014] It is further configured that cables located in the same row are connected in series and the cables are connected through a junction box.

[0015] Beneficial effects of one or more of the above technical solutions:

[0016] The utility model reserves installation gaps between photovoltaic panels in advance during installation, opens a wiring groove on the insulation board behind the photovoltaic panel, and connects the cables to the rear through a junction box at the installation gap after the cables pass through the wiring groove. The cables at the installation gap are arranged in a U shape, thereby reducing the installation gap spacing, and then the cables are fixed to the front glass set above the photovoltaic panel with sealant. The front glass covers the photovoltaic panel and the sealant, and the method of running the cables through the insulation board will not change the structure of the support beam and will not affect the strength of the aluminum alloy column. At the same time, moisture will not penetrate into the junction box after being fixed with sealant, thereby avoiding circuit failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0023] A photovoltaic curtain wall wiring structure, referring to Figure 1 , including several photovoltaic panels 1 arranged adjacent to each other, an insulation board 2 is arranged on the rear side wall of the photovoltaic panel 1, an installation seam 3 is arranged between the photovoltaic panels 1, a wiring groove 4 is opened through the insulation board 2, and a cable 5 is passed through the wiring groove 4. The cables 5 on adjacent photovoltaic panels 1 are connected at the installation seam 3 through a junction box 8, and the junction box and the cable 5 in the installation seam 3 are fixed by a sealant 6.

[0024] The cables 5 at the installation seams 3 are arranged in a U-shape. The cables 5 themselves have a certain flexibility. After being bent, the U-shaped cables 5 can reduce the spacing between the installation seams 3, thereby reducing the overall size of the photovoltaic panel 1.

[0025] The photovoltaic panel 1 is flush with the side of the insulation board 2, and the front side wall of the photovoltaic panel 1 is fitted with a front glass plate 7. The size of the front glass plate 7 is larger than the photovoltaic panel 1. Due to the shielding, the front glass plate 7 is used to cover

[0026] Sealant 6 is provided at a position where the front glass plate 7 is larger than the photovoltaic panel 1 , and the sealant 6 is simultaneously adhered to the photovoltaic panel 1 and the side of the insulation board 2 . The sealant 6 is used to prevent moisture from penetrating into the junction box.

[0027] The insulation board 2 is mounted on the wall, and the sealant 6 is simultaneously pasted between the glass board and the wall. The sealant 6 blocks the air circulation between the bottom of the glass board and the inside of the glass board, thereby preventing moisture from penetrating.

[0028] Reference Figure 2 and Figure 3 The cross section of the wiring trough 4 is rectangular, and the spacing between the wiring troughs 4 is greater than the diameter of the cable 5 to ensure that the cable 5 can pass through the wiring trough 4.

[0029] The wiring trough 4 is arranged close to the bottom end of the photovoltaic panel 1, shortening the distance between the cables 5 arranged in the wiring trough 4 and the ground, thereby facilitating installation by the staff.

[0030] The photovoltaic panels 1 are evenly arranged in the transverse direction and spaced apart in the transverse direction. After the sealant 6 is provided at adjacent locations, the two adjacent rows of curtain wall components can be well connected into one.

[0031] The cables 5 located in the same row are connected in series, and the cables 5 are connected to each other through a junction box. The series arrangement can be arranged along one direction, thereby reducing space and saving costs.

[0032] The wiring steps are as follows:

[0033] During installation, an installation seam 3 is reserved between the photovoltaic panels 1 in advance. A wiring groove 4 is opened on the insulation board 2 behind the photovoltaic panel 1. The cable 5 passes through the wiring groove 4 and is connected to the rear cable 5 through a junction box at the installation seam 3. The cable 5 in the installation seam 3 is arranged in a U shape. The U-shaped arrangement is then maintained by sealant 6. The cable 5 is fixed to the front glass set above the photovoltaic panel 1. The front glass covers the photovoltaic panel 1 and the sealant 6.

[0034] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
