Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic development equipment technology, specifically a rooftop photovoltaic fixing bracket with wind pressure resistance design. Background Technology

[0002] With the advancement of clean energy policies, photovoltaic rooftops have gradually become the main products in the field of building-integrated photovoltaics (BIPV). Rooftops are a common installation location for photovoltaic power stations, with a large usable area, but they also face the impact of different regions, wind speeds, and installation locations. Traditional rooftop photovoltaic mounting brackets have some shortcomings in terms of wind pressure resistance and stable installation. In order to ensure the safety and stability of photovoltaic systems under various conditions, rooftop photovoltaic mounting brackets with wind pressure resistance design have emerged.

[0003] A search revealed existing technology (application number: 202421173456.3), which describes "a lightweight rooftop photovoltaic support". This utility model, a lightweight rooftop photovoltaic support, is characterized by: a frame, surrounding panels, and photovoltaic modules. The frame includes triangular frames and photovoltaic guide rails. The triangular frames are right-angled triangular frames composed of a base beam, columns, and diagonal beams, with connections secured by connectors. Several triangular frames are arranged parallel and equidistantly, and several parallel photovoltaic guide rails are arranged transversely to connect all the triangular frames into a complete frame, with connections secured by connectors. Surround panels are installed at the openings on the sides and back of the frame to cover the openings. The photovoltaic modules are placed on the photovoltaic guide rails, their positions adjusted, and fixed to the frame by pressure blocks. Structural adhesive is applied to the bottom of the base beams, and the frame is fixed to the installation position by bonding.

[0004] However, while existing technologies improve overall stability, facilitate long-term use, and enhance the uniformity of load distribution, thus addressing the overall roof load requirements, they still have some shortcomings: they require a high degree of flatness of the installation base; low tilt angle design may affect the power generation efficiency of photovoltaic modules; and the angle of the triangular frame is fixed, requiring a redesign of the triangular frame if users need to adjust the tilt angle of the photovoltaic modules according to local sunlight conditions, making it difficult to adapt to diverse installation needs.

[0045] Based on Embodiment 1, in order to further improve the applicability of the device, a mounting component and a length component are arranged in the mounting base 1;

[0046] Specifically, the mounting components include: a fixing plate 2, which is rotatably mounted in the middle hole of the crossbeam 3 via a pin at one end of the crossbeam 3, and has multiple sets of round holes in the middle and around the perimeter; and a spring 7, which is installed in the groove of the crossbeam 3, with one end fixedly connected to the inner wall of the groove of the crossbeam 3 and the other end fixedly connected to one side of the vertical beam 4.

[0050] Example 3:

[0051] Based on Example 1, in order to adapt to different lighting environments and ensure the stability of the adjusted device, angle components and locking components are arranged on both sides of the mounting plate 8.

When it is parallel to the mounting plate 8, it can lock the length component. It can be loosened by rotating 90° to complete the angle adjustment of the length component.
