Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic modules, and in particular to a treadable BIPV photovoltaic module based on non-standard floating installation. Background Art

[0002] In the context of global energy transformation, the development and utilization of solar energy as a clean and renewable energy has received widespread attention. Building-in-One Photovoltaics (BIPV) technology has emerged as the times require. It perfectly integrates photovoltaic modules with buildings, which can not only provide electricity for buildings, but also has aesthetic value and environmental significance. However, in the actual application of BIPV technology, especially in the installation of rooftop photovoltaic modules, there are still many challenges. With the increasing demand for diversified use of rooftop space, roofs need to bear more types of loads. For example, on the roofs of some industrial plants, commercial buildings or residential buildings, personnel may perform regular maintenance and inspections, which will inevitably lead to trampling. In snowy weather, In some regions, the weight of snow on the roof is also a load factor that cannot be ignored. At the same time, temporary stacking of debris also occurs from time to time. These complex and diverse loads are a huge test for the traditional rooftop photovoltaic module installation method. The traditional fixed installation mode makes it impossible for photovoltaic modules to effectively buffer and adjust when subjected to external forces, which can easily lead to damage to photovoltaic panels, such as cracks and cell damage, which in turn affects the power generation efficiency and service life of the entire photovoltaic system. Moreover, different roof structures have significant differences in bearing capacity and deformation characteristics, which requires the installation method of photovoltaic modules to adapt to this diversity and flexibly respond to the deformation of different roofs under various loads to ensure that photovoltaic modules are always in a safe and stable working state. At the same time, the rapid development of the photovoltaic industry has led to the increasing diversification of the models and sizes of photovoltaic modules. Different construction projects may choose photovoltaic modules of different specifications according to their own energy needs, roof area and architectural design. However, most of the existing roof photovoltaic module installation structures lack sufficient versatility and adaptability. When installing new photovoltaic modules or upgrading existing photovoltaic systems, if the installation structure is not compatible with different models of photovoltaic modules, it will cause many inconveniences. For example, it may be necessary to redesign and modify the entire installation bracket, which will undoubtedly increase the project cost and construction time. Moreover, during the installation process, if the installation position and fixing cannot be adjusted quickly and accurately, the installation process will be difficult to operate. Inappropriate installation methods will also affect the installation efficiency and quality, and may even cause potential damage to photovoltaic modules due to inappropriate installation methods. In addition, the roof environment is complex and changeable. Different climatic conditions such as strong winds, heavy rains, and temperature changes have put forward higher requirements on the stability and reliability of photovoltaic modules. Under strong winds, photovoltaic modules need to have sufficient wind resistance to avoid being blown off or shifted; when the temperature changes, the installation structure must be able to adapt to the thermal expansion and contraction of photovoltaic modules to prevent damage to the modules due to excessive internal stress. Traditional installation methods often have limitations when dealing with these complex climatic conditions and cannot fully guarantee the stable performance and safe operation of photovoltaic modules during long-term use. Summary of the invention

[0023] Compared with the prior art, the beneficial effects of the present invention are: the treadable BIPV photovoltaic assembly based on non-standard floating installation: 1. When someone steps on the photovoltaic panel or there is pressure generated by snow, debris, etc., the pressure-regulating support mechanism, which is composed of a fixed pressure-bearing platform, a movable pressure-bearing plate, a connecting column, a connecting groove, a piston cylinder and a piston plate, can effectively buffer and disperse the pressure. The pressure is transmitted through the movable pressure-bearing plate, and the pressure between each fixed pressure-bearing platform is balanced through the connecting column and the connecting groove. The piston cylinder and the piston plate can adjust the initial pressure state inside according to the pressure change, thereby avoiding excessive local force on the photovoltaic panel, protecting it from damage, and extending the service life of the photovoltaic module; Furthermore, due to the different bearing capacities and deformation characteristics of different roofs, this non-standard floating installation method can be flexibly adjusted according to the deformation of the roof.

The design of the supporting mechanism solves the problem of the diversity of photovoltaic module models, allowing installers to easily adjust the installation position and fixing method according to the size and shape of different types of photovoltaic panels. For example, by adjusting the position of the displacement bracket on the support seat, and using the positioning column and different positioning holes to change the angle of the fixed support plate and switch the support plate, photovoltaic modules of different specifications can be quickly and accurately limited and supported, which improves the installation efficiency and reduces the cost increase and construction time extension caused by incompatible installation structures; 3. In strong wind weather, the entire BIPV photovoltaic module structure based on non-standard floating installation has better stability. The first metal panel and the second metal panel increase the connection stability and wind resistance with the roof. At the same time, the voltage-adjusting support mechanism and the supporting mechanism can also keep the position of the photovoltaic module stable under wind load to prevent it from being blown off or displaced; Furthermore, in the face of the problem of thermal expansion and contraction of photovoltaic components caused by temperature changes, the floating installation structure of the present invention can effectively adapt to the sliding friction connection between the movable pressure plate and the fixed pressure platform and the setting of the spring, as well as the adjustability of the entire structure, so that when the temperature changes, the internal stress of the component can be effectively released, avoiding damage to the photovoltaic component due to excessive stress caused by thermal expansion and contraction, thereby ensuring the stable performance and safe operation of the photovoltaic component under long-term complex climatic conditions.

At this time, the load is applied to the movable pressure plate 8, and the movable pressure plate 8 slides downward under the action of pressure. At this time, the air in the internal cavity of the fixed pressure platform 7 where the lower end of the movable pressure plate 8 is located is compressed, and the air pressure is mutually transmitted through the connecting column 9 and the connecting groove 10 between the fixed pressure platform 7, so that the load can be evenly dispersed by the movable pressure plate 8 in contact with the photovoltaic panel 6, ensuring that the surface of the photovoltaic panel 6 is evenly stressed. When it is necessary to adjust the supporting force of the movable pressure plate 8 on the photovoltaic panel 6, the adjusting rotary rod 13 is rotated, and the adjusting rotary rod 13 drives the piston plate 12 to slide through the threaded connection with the piston cylinder 11, and the sliding of the piston plate 12 adjusts the initial pressure inside the fixed pressure platform 7.

[0029] Embodiment 2: Based on Embodiment 1, this embodiment discloses that a supporting mechanism is provided on the upper surface of the first metal panel 4 located in the middle section of the roof 1, and the change of the unfolding range is used to adapt to different types of photovoltaic modules; The supporting mechanism includes: a support seat 14, the support seat 14 is fixedly installed with the first metal panel 4 by bolts, and a sliding displacement bracket 15 is mounted on the outer surface of the support seat 14, screw holes are evenly provided on the side surface of the support seat 14, a mounting plate 16 is fixedly provided on the upper end of the displacement bracket 15, and a limiting clamp 17 is fixedly provided on the upper surface of the mounting plate 16, a rotating limiting flap 18 is installed on the side surfaces of both ends of the support seat 14, a positioning plate 19 is fixedly provided on the side surface of the displacement bracket 15, and one end of the positioning plate 19 is fixedly connected to a fixed support plate 20, and a rotating switching support plate 21 is installed on one end of the fixed support plate 20, and the outer surface of the positioning plate 19 is evenly provided with positioning holes 22, and one end of the switching support plate 21 is penetrated by a positioning column 23; The limiting clamp 17 is L-shaped, and the lower surface of one end of the limiting clamp 17 fits the upper surface of the photovoltaic panel 6; A spring is connected between the two limit flaps 18, and one end side surface of the limit flap 18 is in contact with the outer side surface of the displacement bracket 15; The positioning plates 19 are symmetrically arranged on both sides of the mounting plate 16, and the positioning plates 19 are annular in design; The positioning column 23 is slidably connected to the switching support plate 21, and the lower end of the positioning column 23 is plugged into the positioning hole 22. The rotating shaft of the switching support plate 21 is concentrically arranged with the annular positioning plate 19, and the upper surface of the switching support plate 21 is flush with the upper surface of the fixed support plate 20. When installing the photovoltaic panel 6, first place the photovoltaic panel 6 on the upper surface of the movable pressure plate 8, then pinch the limit flaps 18 on both sides to make the limit flaps 18 rotate to let the displacement bracket 15 pass, and the displacement bracket 15 is engaged with the support seat 14 and then slides so that the lower end side surface of the limit clamp 17 fits with the side surface of the photovoltaic panel 6.

The spring between the two limit flaps 18 supports the limit flap 18 so that the limit flap 18 rotates and resets to limit the displacement bracket 15. The displacement bracket 15 cooperates with the upper end circular protrusions of the first metal panels 4 at both ends through the mounting plate 16 and the limit clamp 17 to stably limit the photovoltaic panel 6. When the model of the photovoltaic panel 6 is a non-standard model, after the displacement bracket 15 is installed, the displacement bracket 15 is slid so that the lower end side surface of the limiting clamp 17 fits with the side surface of the photovoltaic panel 6, and then the displacement bracket 15 is limited and blocked by screwing bolts into the screw holes on the outer surface of the support seat 14 so that the displacement bracket 15 cannot slide in the reverse direction, ensuring that the limiting clamp 17 can maintain a stable limit on the photovoltaic panel 6; Then pull out the positioning column 23 and rotate the switching support plate 21. The switching support plate 21 rotates relative to the positioning plate 19 to provide protective support for the lower surface of the photovoltaic panel 6 to prevent the hollow part of the photovoltaic panel 6 from having no effective support when it slides down under a large load. Then the positioning column 23 slides down and engages with the positioning hole 22 to complete the fixation of the relative angle between the fixed support plate 20 and the switching support plate 21.
