Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation technology, and more specifically to a photovoltaic module mounting bracket and a photovoltaic roof installed using the mounting bracket. Background Technology

[0002] With the widespread adoption of photovoltaic modules and the popularization of distributed power generation, more and more photovoltaic modules are being installed on the roofs of buildings such as factories, schools, and houses.

[0003] Currently, some regions in China are gradually developing building-integrated photovoltaic (BIPV) rooftops to replace traditional building rooftops, especially in sparsely populated areas where the cost of self-generation is relatively low. Photovoltaic modules absorb solar energy during the day and convert it into electricity to meet daily household electricity needs. There is also a demand for rooftop photovoltaic systems for distributed home power stations in both urban and rural areas. Furthermore, there is a need to install photovoltaic modules on the rooftops of some public or tourist attractions to meet green and smart energy requirements. Replacing traditional building rooftops with photovoltaic rooftops integrates the solar power generation system with the building while also providing waterproofing, and the photovoltaic rooftop must maintain consistency with the architectural style of the building.

[0004] Photovoltaic modules need to be fixed to the roof of a building using mounting brackets to form a photovoltaic roof. Existing mounting brackets have complex structures, high manufacturing costs, and cannot be mass-produced on an assembly line, making them unsuitable for widespread adoption. Furthermore, the assembly and fixing of mounting brackets is quite cumbersome. Photovoltaic modules installed using mounting brackets are physically extended, occupy a large space, and cannot be integrated with the building itself, altering the original appearance and shape of the building, making them both unsightly and cumbersome.

[0005] Existing photovoltaic roofs are generally made using custom-designed photovoltaic modules. These modules are typically assembled with irregularly shaped frames to achieve an overlapping function, which differs from the frame structure of standard photovoltaic modules. They cannot be assembled and manufactured on existing automated production lines for standard modules, thus preventing mass production and resulting in extremely high manufacturing costs, making widespread adoption difficult. There are also photovoltaic tiles that have been developed. Although they provide good roofing results after installation, their complex structure, special material requirements, low power generation performance, and small total power generation capacity prevent them from fully utilizing solar energy. Summary of the Invention

Therefore, they only show the components related to the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] Example 1

[0040] Please refer to Figure 1 A photovoltaic roof includes a photovoltaic module 1, a pivot seat 2, a hinge shaft 3, a pin shaft 4, and a mounting bracket 5.

[0041] Photovoltaic module 1 includes multiple encapsulated solar cells. Depending on the connection method of the encapsulated solar cells, photovoltaic module 1 includes a first photovoltaic module 11 and a second photovoltaic module 12. Multiple encapsulated solar cells in the first photovoltaic module 11 are connected in series. Multiple encapsulated solar cells in the second photovoltaic module 12 are divided into two groups. One half of the encapsulated solar cells are connected in series to form a series solar cell group, and the other half of the encapsulated solar cells are connected in series to form another series solar cell group. The two series solar cell groups are connected in parallel.

[0042] Preferably, the widths of the first photovoltaic module 11 and the second photovoltaic module 12 are equal, the length of the second photovoltaic module 12 is twice that of the first photovoltaic module 11, and the number of encapsulated solar cells in the second photovoltaic module 12 is twice that in the first photovoltaic module 11. The output voltages of the first photovoltaic module 11 and the second photovoltaic module 12 are equal.

[0043] Reference Figure 2 The rotating shaft seat 2 includes a base 21 and two rotating shaft connecting parts 22. The base 21 is a rectangular flat plate with multiple threaded holes. The base 21 is detachably connected to the photovoltaic module 1 by bolts. The two rotating shaft connecting parts 22 are respectively fixed to both ends of the base 21, and each rotating shaft connecting part 22 has a rotating shaft hole.

[0044] The hinge shaft 3 is a cylindrical long shaft. The hinge shaft 3 is rotatably disposed in the shaft connection part 22 and the shaft hole of the connecting seat, thereby connecting the shaft seat 2 and the mounting bracket 5 together.

[0045] Mounting bracket 5 includes a first mounting bracket 6, a second mounting bracket 7, and a third mounting bracket 8.

[0046] Reference Figure 3 The first mounting bracket 6 includes a first connecting seat 61, a first support member 62, and a first connecting member 63.

[0047] Reference Figure 4The first connecting seat 61 includes a first connecting post 611 and two connecting plates 612. The first connecting post 611 is a hollow quadrangular prism with pivot holes on its two opposite prism faces. Each connecting plate 612 consists of two long flat plates connected at right angles. These plates are fixed to the two prism faces of the first connecting post 611 with pivot holes, and are arranged parallel to each other, forming a locking space between them. Multiple connecting holes are provided on the parallel long flat plates of the two connecting plates 612. The connecting plates 612 are connected to the first support member 62 and the first connecting member 63 by bolts.

[0048] The first support member 62 has a roughly inverted "V" shaped cross-section and includes a base plate 620, two support side plates 621, and two support plates 622. The base plate 620, support side plates 621, and support plates 622 are all elongated flat plates. The two support side plates 621 are vertically fixed to the two long sides of the base plate 620, forming a rectangular drainage channel 623 with the base plate 620. During the installation of the photovoltaic module 1, there is a seam between two adjacent photovoltaic modules 1. The drainage channel 623 is located directly below the seam and can drain rainwater that seeps in from the seam. The support side plates 621 have multiple connection holes and are detachably connected to the first connecting seat 61 and the first connecting member 63 by bolts. The two support plates 622 are arranged parallel to the base plate 620 and are respectively fixed to the two support side plates 621. The support plates 622 are used to support the photovoltaic module 1.

[0049] The first connecting member 63 has a roughly "U"-shaped cross-section and includes a top plate 631, two bottom connecting plates 633, and two connecting side plates 632 connecting the bottom connecting plates 633 and the top plate 631. The top plate 631 and the bottom connecting plates 633 are elongated flat plates, while the two connecting side plates 632 are acute-angled triangular plates. Because the connecting side plates 632 are acute-angled triangular plates, the included angle between the top plate 631 and the bottom connecting plates 633 is an acute angle α. Multiple connecting holes are provided on the two connecting side plates 632, and the connecting side plates 632 are connected to the support side plate 621 of the first support member 62 and two parallel long flat plates of the first connecting seat 61 by bolts. Multiple fixing holes are provided on the bottom connecting plate 633, and the bottom connecting plate 633 is fixedly connected to the roof by screws or bolts.

[0050] The first connecting seat 61, the first support member 62, and the first connecting member 63 are detachably connected by bolts. The specific connection process is as follows: one support plate 622 of the first support member 62 is overlapped on the top plate 631 of the first connecting member 63, and one support side plate 621 of the first support member 62 abuts against one connecting side plate 632 of the first connecting member 63. Then, the first support member 62 and the first connecting member 63 are inserted into the snap-fit ​​space of the first connecting seat 61, so that the two parallel long plates of the first connecting seat 61 are respectively attached to the other support side plate 621 of the first support member 62 and the other connecting side plate 632 of the first connecting member 63. Finally, the two parallel long plates of the first connecting seat are fixedly connected to the support side plate 621 of the first support member 62 and the connecting side plate 632 of the first connecting member 63 by screws.

[0051] The length of the first connector 63 is slightly shorter than that of the first support 62, so that the end of the first support 62 that is not connected to the first connecting seat 61 extends out of the first connector 63. The top plate 631 of the first support 62 is provided with a pin groove hole on the extended part. The first support 62 is connected to the photovoltaic module 1 through the pin 4.

[0052] Reference Figure 5 and Figure 6 The second mounting bracket 7 includes a second connecting seat 71 and a second connecting support 72. The second connecting seat 71 includes a second connecting post 711 and two connecting plates 712. The second connecting post 711 has the same structure as the first connecting post 611 and will not be described in detail. The two connecting plates 712 are long strips and are fixed parallel to the first connecting post 611. The cross-section of the second connecting support 72 is generally an open "C" shape, including an upper support plate 721, a lower connecting plate 723, and a middle side plate 722 vertically connected between the upper support plate 721 and the lower connecting plate 723. The upper support plate 721, the lower connecting plate 723, and the middle side plate 722 are connected to form an open shape. The upper support plate 721 and the lower connecting plate 723 are long flat plates, with the length of the upper support plate 721 being greater than the length of the lower connecting plate 723, causing one end of the upper support plate 721 to extend beyond the lower connecting plate 723. The portion of the upper support plate 721 extending beyond the lower connecting plate 723 has a pin slot. The upper support plate 721 is connected to the photovoltaic module 1 via a pin 4. The middle side plate 722 is an acute-angled triangular plate. Because the middle side plate 722 is an acute-angled triangular plate, the upper support plate 721 and the lower connecting plate 723 are connected at an acute angle, with an included angle of α. The middle side plate 722 has multiple connecting holes and is connected to the two connecting plates 712 of the second connecting seat 71 via bolts. The lower connecting plate 723 has multiple fixing holes and is fixedly connected to the roof via screws. To increase the support strength of the second connecting support member 72, the second connecting support member 72 has multiple ribs 724 between the upper support plate 721 and the lower connecting plate 723.

[0053] The connection process of the second mounting bracket 7 is as follows: insert the two connecting plates of the second connecting seat 71 into the opening of the second connecting support 72, and then use bolts to fix the two connecting plates 712 of the second connecting seat 71 to the middle side plate 722 of the second connecting support 72.

[0054] Reference Figure 7 The structure of the third mounting bracket 8 is the same as that of the second mounting bracket 7, except that the opening direction of the third mounting bracket 8 is opposite to that of the second mounting bracket 7.

[0055] The installation process for fixed photovoltaic systems is as follows:

[0056] 1. Secure the first mounting bracket 6, the second mounting bracket 7, and the third mounting bracket 8 to the roof with screws. The second mounting bracket 7 and the third mounting bracket 8 are fixed to the two sides of the roof, and the first mounting bracket is installed between the second mounting bracket 7 and the third mounting bracket 8.

[0057] 2. Fix the rotating shaft seat 2 to the photovoltaic module 1 with bolts;

[0058] 3. Place the photovoltaic module 1 on the mounting bracket 5, hinge one end to the connecting seat of the mounting bracket 5 with the hinge shaft 3, and fix the other end to the mounting bracket 5 with the pin shaft 4.

[0059] The arrangement of the first photovoltaic module 11 and the second photovoltaic module 12 can be reasonably arranged according to the actual situation.

[0060] Reference Figure 8 A preferred roof installation method is that the second photovoltaic module 12 and the first photovoltaic module 11 are arranged in a stacked manner. Since the angle between the top and bottom connecting plate 633 of the first connector 63 is α, and the angle between the upper support plate 721 and the lower connecting plate of the second connecting support 72 and the third connecting support is α, the photovoltaic standard module has a certain angle α with the roof surface after installation. This allows the lower edge of the second photovoltaic standard module located on the upper side to be stacked on top of the upper edge of the next photovoltaic module 1 located on the lower side of the first photovoltaic module 11. The upper edge of the first photovoltaic module 11 located below is set below the top plate 631 and the extension of the upper support plate 721 of the mounting bracket 5, forming a stacked overlapping form. The upper and lower overlap has a certain width, and the gaps in the overlap are covered with water-blocking strips to prevent rainwater from splashing.
