Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and in particular to a fixed photovoltaic bracket and a photovoltaic module. Background Art

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy. With the introduction of the national "dual carbon" indicators, the application of photovoltaic power generation technology is increasing. With the continuous iteration of photovoltaic technology, photovoltaic projects such as mountain photovoltaics and fishery photovoltaics have gradually become the mainstream trend. Mountain photovoltaics and fishery photovoltaics are mainly built in areas with high intensity and strong wind pressure, requiring photovoltaic modules to have good wind pressure resistance.

[0003] In the related art, the photovoltaic panels of the photovoltaic module are generally installed at the target location through a fixed photovoltaic bracket. When the photovoltaic panels and the photovoltaic bracket are installed, the photovoltaic panels are usually directly connected to the supporting structure of the bracket through fasteners to form a rigid fixed structure.

[0004] However, in the above-mentioned related technologies, when photovoltaic modules are applied to projects such as mountain photovoltaics and fish-photovoltaic complementary projects, the photovoltaic modules need to be set up in an environment with frequent wind conditions and high wind pressure intensity. Affected by wind loads and seismic loads, the vibration of the photovoltaic modules can easily cause hidden cracks in the photovoltaic panels, affecting the life of the photovoltaic modules.

[0016] In an optional embodiment, the转接结构 (transfer structure) is a purlin, the purlin is fixedly connected to the energy dissipation support, and the photovoltaic panel is fixedly connected to the side of the purlin away from the diagonal beam.

[0017] Beneficial effects: By using a purlin as the transfer structure, while reducing the overall weight, it also provides sufficient support area for the photovoltaic panel.

The energy-absorbing support 200 is installed on the photovoltaic bracket and connected to the photovoltaic panel 500 through the adapter structure 300. When the photovoltaic panel 500 and the photovoltaic bracket are affected by wind loads and seismic loads, the energy-absorbing support 200 can effectively reduce the transmission of vibration between the energy-absorbing support 200 and the photovoltaic panel 500, and change the natural frequency of the overall structure, thereby protecting the photovoltaic panel 500. While ensuring the energy-absorbing performance, the support structure 100 can still be arranged in a rigid structure and a rigid connection method, so that the photovoltaic module as a whole has good rigidity. When the support structure 100 is arranged in a water body, the support structure 100 has a good ability to resist water disturbances such as tides and waves.

There are at least two inclined beams 105 and they are respectively arranged on the second column 102 and the third column 103. One end of the inclined beam 105 is connected to the second column 102 or the third column 103, and the other end is connected to the inclined beam 105. The surface of one side of the inclined beam 105 away from the second column 102 and the third column 103 is the installation surface.

[0045] Specifically, this embodiment does not limit the specific fixing method between the second column 102 or the third column 103 and the ground. The first column 101 can be directly inserted into the ground, or it can be fixed to the ground by cooperating with other structural members and setting with concrete foundation piles.

[0046] In this embodiment, by setting the second column 102 and the third column 103, the double column structure provides a positioning and installation basis for other components of the support structure 100, thereby improving the stress condition of the overall structure, so that the photovoltaic module has better structural stability and can withstand greater wind pressure. The second column 102 and the third column 103 are respectively combined with the corresponding support rods 104 and inclined beams 105 to form a triangular support structure 100, thereby improving the overall structural strength.

[0048] In this embodiment, since the support rod 104, the second column 102, the third column 103 and the inclined beam 105 are all connected in a hinged manner, under the premise that the inclined beam 105, the support rod 104 and the second column 102 or the third column 103 form a triangular support structure 100, the use of a hinged flexible connection method can not only ensure the structural strength of the support structure 100, but also reduce the transmission of vibration, change the natural frequency to a certain extent, and further enhance the protection effect of the photovoltaic panel 500.

[0049] In one embodiment, the transition structure 300 is a purlin 301 , the purlin 301 is fixedly connected to the energy dissipation support 200 , and the photovoltaic panel 500 is fixedly connected to a side of the purlin 301 away from the inclined beam 105 .

The plurality of purlins 301 are arranged in parallel and jointly connect and support the photovoltaic panel 500.

[0053] In this embodiment, the purlin 301 is arranged parallel to the installation surface and perpendicular to the inclined beam 105, so that the plurality of purlins 301 are arranged in parallel intervals from high to low on the inclined beam 105. During installation, it is easier to position and control the installation positions of the respective purlins 301, and the force transmission between the photovoltaic panel 500 and each purlin 301 is more uniform, reducing the uneven local pressure of the photovoltaic panel 500.
