Description

Technical Field

[0001] This utility model relates to the field of photovoltaic building shading grille technology, specifically a photovoltaic building shading grille. Background Technology

[0002] Building photovoltaic (PV) shading grilles, as composite structures integrating photovoltaic panels and building shading functions, possess both the shading and decorative functions of traditional building shading grilles and the ability to convert solar energy into electricity through the photovoltaic effect, leading to their widespread application in green building. Currently, existing PV shading grilles typically have pre-installed gaps between the PV panels. These gaps primarily accommodate mounting brackets, wiring terminals, and other components, adapting to the thermal expansion and contraction of the PV panels while also providing drainage, ventilation, and reducing self-shading. However, these PV panel gaps are mostly designed with fixed dimensions; their width is determined during product manufacturing or installation and cannot be dynamically adjusted according to actual usage scenarios. In practical applications, when enhanced ventilation is needed indoors, the fixed gap width is insufficient to meet the demand for greater airflow. In scenarios where ventilation is not required, the fixed gap cannot be narrowed or closed, allowing rainwater to easily seep into the room and causing heat loss. Furthermore, light leakage through the gap reduces the overall light-receiving efficiency of the photovoltaic modules, thus affecting the comprehensive optimization of shading, power generation, and energy-saving effects. This makes it difficult to flexibly adapt to the building usage needs of different times and environments, limiting the functionality, practicality, and applicability of photovoltaic building shading grilles.

[0003] Therefore, this utility model provides a photovoltaic building shading grille. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A photovoltaic building shading grille includes several photovoltaic panels 1 and several track mounting frames 11. Several grilles 2 are provided between two adjacent track mounting frames 11. Each grille 2 includes two mounting plates 21 and several shading sheets 22. The mounting plates 21 are installed on one side of the corresponding track mounting frame 11, and the shading sheets 22 are installed between two corresponding mounting plates 21. Two windproof plates 3 are provided between every two photovoltaic panels 1. Two central poles 31 are provided between two windproof plates 3 at corresponding positions. The windproof plates 3 are rotatably connected to the outside of the corresponding central poles 31.

[0021] Specifically, the device consists of several photovoltaic panels 1, track mounting frames 11, and grilles 2. The grilles 2 are fixed to the track mounting frames 11 by mounting plates 21 and achieve basic shading with the help of shading sheets 22. Two windproof plates 3 are set between every two photovoltaic panels 1, which rotate around the corresponding central pole 31. The two windproof plates 3 can be opened or folded on the central pole 31 like hinges. When the indoor ventilation effect needs to be enhanced, the windproof plates 3 are controlled to rotate and unfold around the central pole 31 in a direction away from the gaps of the photovoltaic panels 1, thereby increasing the gaps between the photovoltaic panels 1 and increasing the airflow channels to meet greater ventilation needs. When ventilation is not required, such as in rainy weather, winter insulation, or when pursuing high power generation efficiency, the windproof plates 3 are controlled to rotate around the central pole 31 towards the gaps of the photovoltaic panels 1. Folding, narrowing, or even closing the gaps between photovoltaic panels 1, the space in the gaps is then blocked by the windproof plate 3. This prevents rainwater from seeping into the room through the gaps, reduces heat loss through the gaps, and blocks light leakage through the gaps, thus improving the overall light-receiving efficiency of photovoltaic panels 1. The flip-up and foldable design of the windproof plate 3 solves the problem of the fixed gaps in photovoltaic panels 1 that cannot be dynamically adjusted: it retains the original basic functions of the gaps, such as accommodating components and adapting to thermal expansion and contraction, while also enabling flexible adjustment of the gap width. It can automatically switch between ventilation, rain protection, heat preservation, and power generation efficiency improvement functions according to the building's usage needs at different times and in different environments, effectively optimizing the comprehensive effects of shading, power generation, and energy saving, and improving the functionality, practicality, and applicability of photovoltaic building shading grilles.

[0022] In one embodiment of this utility model, such as Figures 1-4As shown, a connecting plate 4 is installed on one side of each of the several central rods 31. The connecting plate 4 has a movable hole 41. A slider 42 is slidably connected to the inner wall of the movable hole 41. A traction rod 43 is hinged to both sides of the slider 42. One end of the traction rod 43 is hinged to the side wall of the corresponding windproof plate 3.

[0023] Specifically, when the drive slider 42 slides within the movable hole 41, the slider 42 will synchronously drive the wind shields 3 on both sides to rotate around the central rod 31 via the traction rod 43, thereby realizing the unfolding or folding action of the wind shields 3, and thus adjusting the width of the gap between the photovoltaic panels 1.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, both sides of the connecting plate 4 are provided with clearance recesses 44, which correspond to the positions of the windshield plate 3.

[0025] Specifically, clearance notches 44 are opened on both sides of the connecting plate 4, corresponding to the positions of the windshield 3. When the windshield 3 is flipped and unfolded or folded around the central rod 31, the clearance notches 44 will provide enough space for the rotation of the windshield 3, avoiding collision or interference between the windshield 3 and the connecting plate 4, ensuring that the flipping action of the windshield 3 is completed smoothly, thereby ensuring that the adjustment process of the gap width between the photovoltaic panels 1 is stable and unobstructed.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, a push-pull rod 45 is slidably connected to the inner wall of the connecting plate 4. One end of the push-pull rod 45 is installed on one side of the slider 42. A vertical rod 46 is provided between the two connecting plates 4, and the push-pull rod 45 is installed on one side of the corresponding vertical rod 46.

[0027] Specifically, when the driving rod 46 moves, the rod 46 will simultaneously drive the push-pull rod 45 to slide within the connecting plate 4. The push-pull rod 45 will then drive the slider 42 to slide within the movable hole 41. Finally, the windproof plate 3 will be controlled to rotate around the central rod 31 by the traction rod 43, thereby adjusting the gap width between the photovoltaic panels 1.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a first insert rod 32 is installed at the top of the wind shield 3, and a first connecting hole 33 is opened at the bottom of the wind shield 3. The first insert rod 32 is inserted into the inner wall of the first connecting hole 33.

[0029] Specifically, a first insert rod 32 is installed at the top of the wind shield 3, and a first connecting hole 33 is opened at the bottom of the wind shield 3. When two adjacent wind shields 3 are flipped and folded around the central rod 31 to reduce or close the gap between the photovoltaic panels 1, the first insert rod 32 of the upper wind shield 3 will be precisely inserted into the inner wall of the first connecting hole 33 of the corresponding lower wind shield 3, so that the adjacent wind shields 3 form a tightly spliced ​​overall structure to ensure the airtightness of the gap. When the wind shield 3 is flipped and unfolded to expand the gap, the first insert rod 32 separates from the first connecting hole 33, without affecting the opening and ventilation effect of the gap, and forms a synchronous linkage.

[0030] In one embodiment of this utility model, such as Figures 1-4 As shown, a second insertion rod 461 is installed at the top of the plumb rod 46, and a second connecting hole 462 is opened at the bottom of the plumb rod 46. The second insertion rod 461 is inserted into the inner wall of the second connecting hole 462.

[0031] Specifically, a second insert rod 461 is installed at the top of the vertical rod 46, and a second connecting hole 462 is opened at the bottom of the vertical rod 46. When it is necessary to adjust the gaps between multiple photovoltaic panels 1 synchronously, adjacent vertical rods 46 can be spliced ​​and fixed by inserting the second insert rod 461 and the second connecting hole 462, so that multiple vertical rods 46 form a continuous overall structure. When driving the spliced ​​vertical rods 46 to move as a whole, the push-pull rod 45 can be used to drive all corresponding sliders 42 to slide synchronously, and then the traction rod 43 can be used to control all wind shields 3 to rotate synchronously around the central rod 31, so as to achieve uniform adjustment of the gap width between all photovoltaic panels 1. When disassembling, it is only necessary to separate the second insert rod 461 from the second connecting hole 462 to achieve independent control of a single vertical rod 46 or disassembly and adjustment of the overall structure.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: The system consists of several photovoltaic panels 1, track mounting frames 11, and grilles 2. The grilles 2 are fixed to the track mounting frames 11 by mounting plates 21, and basic shading is achieved using shading sheets 22. Two windproof plates 3 are installed between every two photovoltaic panels 1. The windproof plates 3 rotate around the central rod 31, unfolding or folding like hinges to adjust the width of the gap between the photovoltaic panels 1. When ventilation is needed, they unfold to expand the gap; when ventilation is not needed, they fold to shrink or close the gap, blocking rainwater, reducing heat loss, and preventing light leakage. On the connecting plate 4 on one side of the central rod 31, the slider 42 in the movable hole 41 is connected to the windproof plate 3 through the two side traction rods 43. The slider 42 moves... When in motion, the windshield 3 is rotated; the clearance notch 44 of the connecting plate 4 prevents the windshield 3 from interfering with the connecting plate 4 when it is rotated; the push-pull rod 45 inside the connecting plate 4 connects the slider 42 and the vertical rod 46; the vertical rod 46 can be driven by the push-pull rod 45 to drive the slider 42 to slide, thereby adjusting the windshield 3; the first insertion rod 32 of the windshield 3 is inserted into the first connecting hole 33 of the lower windshield 3 to enhance the sealing when folded; the second insertion rod 461 of the vertical rod 46 is inserted into the second connecting hole 462 of the lower vertical rod 46 to achieve splicing of multiple vertical rods 46, simultaneously adjusting multiple sets of gaps, and can be independently controlled after disassembly, thus flexibly adapting to different scene requirements.
