Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically to a photovoltaic component curtain wall installation system. Background Art

[0002] Solar energy is a clean, economical and stable energy source, which has been widely used in the world. Countries around the world have conducted a lot of research on it, trying to improve its photoelectric and photothermal conversion efficiency, so as to provide clean energy. The combination of solar photovoltaic system and architecture reflects the application of sustainable development. In addition to being beautiful and having power generation functions, it also has the necessary performance and unique decorative functions of wind pressure resistance, watertightness, airtightness, sound insulation, heat preservation and sunshade, etc. for building enclosure, achieving a perfect combination of building enclosure, building energy conservation, solar energy utilization and building decoration. The international community attaches great importance to it and it is increasingly being promoted.

[0003] At present, with the annual increase in the installed capacity of large-scale ground photovoltaic power stations and distributed photovoltaic power stations, suitable sites are becoming increasingly scarce, requiring a variety of photovoltaic installation component types and installation methods. Large-scale ground photovoltaic power stations and most distributed photovoltaic power stations are built on flat surfaces, roofs or slopes. The photovoltaic curtain wall is fixed to the vertical wall or floor through a bracket. The advantage is that there is no need to consider rain and snow loads, accumulated soil, ash, bird droppings, etc., and the self-purification ability is also stronger, which can also make the building more beautiful. Some traditional installation methods are to lift the photovoltaic components and hang them vertically downward on the installation components, which is more difficult to install.

[0029] The steel section 5 is fixed relative to the wall 1. In this embodiment, the steel section 5 is U-shaped, and a plurality of through holes are provided at intervals at the bottom of the U-shaped steel section. The photovoltaic module curtain wall installation system also includes a support member 4, which is connected to the wall 1 through a locking member 6, and the steel section 5 is fixed to the support member 4. Specifically, the support member 4 is L-shaped, and one side is fixedly connected to the wall 1 through a locking member 6, and the locking member 6 can be a connecting fixture such as an expansion bolt; the other side of the support member 4 is connected to the bottom of the steel section 5, and the through hole at the bottom of the steel section 5 is connected to the bolt, and is connected to the support member 4 through the bolt.

[0030] The U-shaped steel 5 has two opposite sides respectively connected to the bottom of the steel, and a first hook is provided at least on the side of the steel 5 away from the wall 1. In this embodiment, the first hook is provided above both opposite sides. Figure 1 and Figure 2 As shown, the side of the steel section 5 away from the wall 1 is used for illustration, one end of the upper side is connected to the first steel section side 51, the first steel section side 51 extends toward the direction close to the wall 1, and the other end of the first steel section side 51 is connected to the second steel section side 52, the second steel section side 52 extends downward, so that the first steel section side 51 and the second steel section side 52 form a first hook.

[0031] The upper hanger 3 is fixed on the back of the photovoltaic panel 2, combined with Figure 4 As shown, one end of the upper hanger 3 is connected to the first upper hanger side 31, and the other end of the first upper hanger side 31 is connected to the second upper hanger side 32. The second upper hanger side 32 extends downward, so that the first upper hanger side 31 and the second upper hanger side 32 form a second hook. The upper hanger 3 is arranged near the top of the photovoltaic panel 2 and is used to connect with the steel section 5. At least two steel sections 5 are arranged on the back of each photovoltaic panel 2, and the upper hanger 3 is connected to one of the steel sections 5.

[0032] In this embodiment, when the upper hanger 3 is connected to the steel 5, the second hook is connected to the first hook, and the first hook is located inside the second hook. Specifically, the first steel side 51 contacts the first upper hanger side 31, the second steel side 52 contacts the second upper hanger side 32, and the length relationship between the first steel side 51 and the first upper hanger side 31, the length relationship between the second steel side 52 and the second upper hanger side 32, and the position of the upper hanger 3 close to the photovoltaic panel 2 can enable the photovoltaic panel 2 to rotate around the first hook by a maximum of 45°.

[0033] Combination Figure 6 and Figure 7As shown, the photovoltaic panel 2 has a certain rotation angle. On the one hand, during installation, the photovoltaic panel 2 can be manually installed on the steel section 5 at an angle relative to the vertical surface of the wall 1, making the installation process more labor-saving; on the other hand, after the second hook is connected to the first hook, the photovoltaic panel 2 can be lifted from the bottom to carry out the operation of docking the DC cable connector, and the cable can also be hidden on the back of the photovoltaic panel 2 to improve the appearance of the photovoltaic curtain wall; and the second hook and the first hook can be positioned relative to each other in the horizontal direction, without the need to add other fixings or adhesives to position the photovoltaic panel.

The connecting hook formed by the first lower hanging member side 71 and the second lower hanging member side 72 is clamped to the first hook of the steel section 5.

[0038] In the above, the connection between the lower hanger 7 and the steel section 5 can be completed after the connecting hook and the first hook are locked together. The connecting hook and the first hook can be positioned with each other, and there is no need to add other fixed connections to fix the photovoltaic panel. The installation system is simple and convenient.
