Description

Technical Field

[0001] The present invention belongs to the field of photovoltaics, and in particular relates to a BIPV roof photovoltaic module installation structure with a reinforced fixing structure. Background Art

[0002] With the development of photovoltaic technology, the size of photovoltaic modules is also developing in the direction of being longer and larger. Due to considerations of installation and material costs, the installation and fixing points of the trough-type BIPV modules are all on the short sides of the modules. Therefore, the deformation problem in the length direction of the modules is particularly prominent, and the need to solve this problem is very urgent.

[0003] In the current BIPV rooftop photovoltaic module installation solutions on the market, a support beam is usually added at 1 / 2 of the length of the photovoltaic module to resist the downward disturbance under the weight and load of the module.

[0004] However, this installation plan only considers the problem of downward interference from photovoltaic modules. When photovoltaic modules are installed on the roof of a building, the negative wind pressure caused by wind will have a more prominent impact on the photovoltaic modules, while this installation plan does not solve the problem of upward pressure from the modules.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1

[0030] See also Figure 1-5 A BIPV rooftop photovoltaic module mounting structure with a reinforced fixing structure includes a photovoltaic module and a support beam 1, which are conventionally mounted on a building purlin 7. The photovoltaic module is supported by the support beam 1. The bottom of the photovoltaic module is fixedly connected to the fixing assembly, which cooperates with the support beam 1 in the upper and lower directions to limit the upward movement of the fixing assembly.

[0031] It can be understood that in the above technical solution, this embodiment adds a fixing component, which is limited and matched with the support beam 1 to achieve interlocking. The interlocking design of the fixing component and the support beam improves the installation reliability of the photovoltaic module.

[0032] Continue reading Figure 3 The fixing assembly includes a first fixing member 2 and a second fixing member 3 which are connected separately. The first fixing member 2 is fixedly connected to the photovoltaic assembly, and the second fixing member 3 is limitedly matched with the support beam 1.

[0033] Continue reading Figure 4The first fixing part 2 includes a first fixing part connection part 1 200, a first fixing part connection part 201 and a first fixing part connection part 3 202. The photovoltaic module includes a module body 4 and a module frame 5 arranged around the module body 4. The first fixing part connection part 1 200 is fixedly connected to the module body 4 by structural adhesive 6. The first fixing part connection part 1 200 has a corresponding glue overflow hole. The pulling performance of the photovoltaic module is mainly satisfied by the bonding of the structural adhesive 6. The first fixing part connection part 201 is fixedly connected to the module frame 5 by rivets. The first fixing part connection part 201 plays a role of temporary fixation and precise positioning. The first fixing part connection part 3 202 is fixedly connected to the second fixing part 3 by fasteners.

[0034] Among them, the first fixing member connection part 1 200 is located at the top of the first fixing member 2, the first fixing member connection part 2 201 and the first fixing member connection part 3 202 are respectively located on two adjacent sides of the first fixing member 2, and the first fixing member connection part 1 200, the first fixing member connection part 201 and the first fixing member connection part 3 202 are perpendicular to each other.

[0035] Continue reading Figure 2 、 5 The main body of the second fixing member 3 is fixedly connected to the first fixing member 2 by fasteners, and its lower end has a first limiting portion 300, and the support beam 1 has a second limiting portion 100, and the first limiting portion 300 is limited and matched with the second limiting portion 100.

[0036] Specifically, the first limiting portion 300 is a hook-shaped structure, the support beam 1 is a U-shaped structure, and the two sides of its opening are rolled inward to form a groove-shaped structure. The second limiting portion 100 is a groove-shaped structure, and the hook-shaped structure is hooked with the groove-shaped structure to achieve interlocking of the second fixing frame 3 and the support beam 1. This interlocking design improves the installation reliability of the photovoltaic module.

[0037] The above-mentioned first fixing member 2 and second fixing member 3 adopt a split design, considering that the installation of the fixing component will not affect the normal packaging and transportation of the photovoltaic component. After the first fixing member 2 is installed at the photovoltaic component manufacturer, the second fixing member 3 is installed at the construction site.

[0038] Example 2

[0039] See also Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that in the first fixing member 2 of this embodiment, reinforcing ribs 203 are provided between the first fixing member connection part 1 200 and the first fixing member connection part 2 201, and between the first fixing member connection part 1 200 and the first fixing member connection part 3 202. The reinforcing ribs 203 are forged from the outside toward the inside of the corner, and the reinforcing ribs 203 can enhance the structural strength of the first fixing member 2.

[0040] Example 3

[0041] See also Figure 8 The difference between this embodiment and embodiment 1 is that the first fixing member 2 and the second fixing member 3 in this embodiment are integrally connected, and the two form an integrated structure.
