Description

Technical Field

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

[0002] Photovoltaic curtain wall is a curtain wall structure that is pasted on glass and embedded between two pieces of glass. It can convert light energy into electrical energy through batteries. It is also called solar photovoltaic curtain wall. Photovoltaic curtain wall uses photovoltaic cells and photovoltaic panel technology to convert sunlight into electrical energy. Its key technology is solar photovoltaic cell technology. Solar photovoltaic cells use the photon energy of sunlight to move electrons in the irradiated electrolyte or semiconductor material, thereby generating voltage.

[0003] Solar energy is an inexhaustible energy source. In order to convert solar energy into usable energy without pollution, photovoltaic curtain wall technology came into being. Photovoltaic curtain wall is a new type of building curtain wall structure that combines traditional curtain wall with photovoltaic effect. In addition to the performance of ordinary curtain wall, the biggest feature of photovoltaic curtain wall is that it can convert light energy into electrical energy. Solar cells use the photon energy of sunlight to make the electrons of the irradiated electrolyte or semiconductor material move, thereby generating voltage.

[0004] At present, the application of photovoltaic curtain walls is becoming more and more widespread, and more and more photovoltaic curtain walls are beginning to be used on the facades of curtain walls. However, in order to meet the requirements of natural ventilation, opening windows are set on the facades of curtain walls, and the application of photovoltaic curtain wall opening windows is very rare. The main reason is that the structure and setting of the photovoltaic curtain wall opening window threading are difficult. First, the threading affects the normal opening and closing of the opening window. Second, the threading may be exposed, affecting the visual effect. Third, the threading causes the water tightness and air tightness to deteriorate.

[0005] Chinese patent number CN218301344U discloses a photovoltaic unit, an interlayer photovoltaic curtain wall and a building, including a photovoltaic module, a connector, and a sub-frame. A junction box is installed on the backlight surface of the photovoltaic module; the connector is electrically connected to the junction box; the sub-frame is arranged on opposite sides of the backlight surface of the photovoltaic module, and the sub-frame has a threading hole, which is used to lead out the connector or the junction box.

[0006] The photovoltaic curtain wall disclosed above realizes the connection of the lines under the action of the sub-frame and the junction box through the design of the sub-frame and the junction box. However, since the junction box is connected to the photovoltaic curtain wall and the sub-frame is arranged on the side of the photovoltaic curtain wall, when it is necessary to set an opening window on the photovoltaic curtain wall, the relative position of the sub-frame and the junction box will change, which will cause the extrusion or tension of the lines, so that the threading method of the above-mentioned photovoltaic curtain wall will affect the normal opening and closing of the opening window.

DETAILED DESCRIPTION

[0026] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, a wiring structure for an opening fan of a photovoltaic curtain wall includes a first photovoltaic glass 1 and a second photovoltaic glass 2 serving as an opening fan, a photovoltaic cable 6 connected to each other is provided between the first photovoltaic glass 1 and the second photovoltaic glass 2; an aluminum alloy crossbeam 3 is installed on the backlight surface of the first photovoltaic glass 1, an aluminum alloy opening fan frame 8 is installed on the backlight surface of the second photovoltaic glass 2, and an aluminum alloy frame 7 matched with the aluminum alloy opening fan frame 8 is installed on the aluminum alloy crossbeam 3; the photovoltaic cable 6 is connected to the aluminum alloy crossbeam 3, and the photovoltaic cable 6 in the aluminum alloy crossbeam 3 has a telescopic margin that satisfies the opening and closing of the second photovoltaic glass 2.

[0028] The first photovoltaic glass 1 is always in a relatively static state, and the second photovoltaic glass 2 can rotate so that the second photovoltaic glass 2 can be used as an opening window. The second photovoltaic glass 2 will synchronously expand and contract the photovoltaic cable 6 when in the open and closed states, and the expansion margin in the aluminum alloy beam 3 can ensure the expansion and contraction amount of the photovoltaic cable 6 by the second photovoltaic glass 2 when in the open and closed states, thereby ensuring the stability of the photovoltaic cable 6 when the second photovoltaic glass 2 is opened and closed.

[0029] An aluminum alloy front cavity 31 and an aluminum alloy rear cavity 32 are formed in the aluminum alloy beam 3 . An aluminum alloy partition 33 for separating the aluminum alloy front cavity 31 and the aluminum alloy rear cavity 32 is formed in the aluminum alloy beam 3 . The aluminum alloy front cavity 31 is located between the first photovoltaic glass 1 and the aluminum alloy rear cavity 32 .

[0030] The photovoltaic cable 6 includes a fixed section 61 and a slack section 62 located at opposite ends of the fixed section 61. The telescopic margin is formed on the slack section 62, and the fixed section 61 is located in the middle of the photovoltaic cable 6. Under the action of the fixed section 61, the slack sections 62 at both ends of the fixed section 61 are symmetrically arranged, and the telescopic deformation of the slack sections 62 in the aluminum alloy front cavity 31 is ensured at the same time. In the case that there are slack sections 62 at both ends of the fixed section 61, there is no need to consider the position of the opening fan during the installation process.

[0031] The fixed section 61 is located in the aluminum alloy rear cavity 32 , and the loose section 62 is located in the aluminum alloy front cavity 31 . Combined with the setting of the aluminum alloy partition 33 , the fixed section 61 and the cable pressing block 5 can be abutted against each other, thereby ensuring the stability of the fixed section 61 .

The cable pressing block 5 forms an arc structure adapted to the photovoltaic cable 6. The diameter of the arc position is determined by the diameter of the photovoltaic cable 6. The rubber gasket 51 has the following functions: first, to protect the photovoltaic cable 6; second, to increase the friction between the photovoltaic cable 6 and the photovoltaic cable 6 after the photovoltaic cable 6 is compressed, thereby tightening the photovoltaic cable 6.

[0035] The aluminum alloy rear cavity 32 is a slotted structure for facilitating the installation of the cable pressing block 5 and the self-tapping screws 52 , and a beam buckle cover 4 for hiding the photovoltaic cable 6 is installed on the back of the aluminum alloy beam 3 .

[0037] The size of the milled circular hole is determined according to the diameter of the photovoltaic cable 6. The photovoltaic cable 6 will pass through the milled circular holes on the aluminum alloy opening fan frame 8, the aluminum alloy beam 3 and the aluminum alloy partition 33, and the photovoltaic cable 6 will be pressed against the aluminum alloy partition 33 by the cable pressing block 5 to prevent the cable pressing block 5 from moving.

[0038] Milling circular holes on the aluminum alloy opening sash frame 8, aluminum alloy beam 3 and aluminum alloy partition 33 will not damage the waterproof structures such as the rubber strips and sealants of the original curtain wall system, and the nylon ring 9 will be put on the circular holes milled by the aluminum alloy opening sash frame 8, aluminum alloy beam 3 and aluminum alloy partition 33 to avoid damage to the photovoltaic cable 6 by tensioning friction.

[0039] During actual use, the photovoltaic cable 6 is a component on the second photovoltaic glass 2. The photovoltaic cable 6 passes through the circular holes milled on the aluminum alloy opening fan frame 8, the aluminum alloy beam 3 and the aluminum alloy partition 33 and is connected to the first photovoltaic glass 1. The photovoltaic cable 6 is hidden by buckling the aluminum alloy beam cover.

[0040] When installing and threading the photovoltaic curtain wall opening window, first make circular holes on the aluminum alloy opening sash frame 8, aluminum alloy beam 3 and aluminum alloy partition 33 in the processing plant and install nylon ring 9. After the aluminum alloy opening sash frame 8, aluminum alloy beam 3 and other curtain wall components are installed, install the opening window, pass the photovoltaic cable 6 through the circular holes on the aluminum alloy opening sash frame 8 and the aluminum alloy beam 3 in turn, and ensure that the photovoltaic cable 6 is in a relaxed state in the aluminum alloy front cavity 31, and press the photovoltaic cable 6 near the circular hole in the aluminum alloy rear cavity 32 through the cable pressing block 5.
