Description

Technical Field

[0001] This application relates to the field of installation technology, and in particular to a multifunctional bracket for prefabricated exterior walls. Background Technology

[0002] Photovoltaic panels, as devices that convert solar energy into electrical energy, primarily function to absorb solar radiation energy and convert it into directly usable direct current (DC) through the photovoltaic effect of semiconductor materials. This DC power then supplies electricity to various electrical devices or is stored in batteries. Currently, photovoltaic panels are widely used in various fields, including homes, industry, and commerce.

[0003] To further improve the utilization rate of photovoltaic panels and expand the area for solar energy collection, the application scenarios of photovoltaic panels are gradually extending from traditional areas such as rooftops and ground surfaces to building facades. Installing photovoltaic panels on building facades can make full use of the unused space in the building envelope, and the photovoltaic panels themselves can provide a certain degree of shading and heat insulation, reducing building air conditioning energy consumption and achieving synergy between building energy conservation and energy production.

[0004] However, current photovoltaic panels used on building exteriors still have significant limitations: most commercially available exterior photovoltaic panels are made of monocrystalline silicon, which, to ensure high photoelectric conversion efficiency, typically lacks light transmittance and can only be installed on the solid wall portion of a building's facade. For window areas on building exteriors, monocrystalline silicon photovoltaic panels completely block light, affecting indoor lighting, making them unsuitable for installation. This results in unused exterior space around windows, limiting the overall installation area of ​​exterior photovoltaic panels and hindering the full utilization of the building's exterior solar energy collection potential. Utility Model Content

[0005] Therefore, it is necessary to provide a prefabricated multi-functional bracket for exterior wall decoration, which addresses the limitation of existing exterior wall photovoltaic panels in terms of their inability to be adapted to window areas due to the lack of light transmission of monocrystalline silicon material, thus restricting the installation area.

[0007] The first bracket is used to connect to the exterior facade;

[0008] A first photovoltaic panel is mounted on the first support and can be positioned opposite a window on the exterior facade. The light transmittance of the first photovoltaic panel is greater than or equal to 40%.

[0009] The second bracket is used to connect to the exterior facade and is located below the first bracket. The second bracket has a receiving space.

[0010] The second photovoltaic panel is located on the side of the second support that faces away from the exterior facade.

[0011] In one embodiment, it further includes a first locking member and a first sealing member, and a first through hole is provided on the exterior facade. The first locking member passes through the first bracket and the first through hole to connect the first bracket and the exterior facade.

[0012] The first sealing component includes a first waterproof sealing ring and a first windproof baffle. The first waterproof sealing ring is sleeved on the first locking component and fits against the hole wall of the first through hole. The first windproof baffle covers the outside of the first through hole and is sealed to the first bracket and the surface of the outer facade.

[0013] In one embodiment, a second locking member and a second sealing member are also included. A second pair of through holes are provided on the exterior facade. The second locking member passes through the second bracket and the second pair of through holes to connect the second bracket and the exterior facade.

[0014] The second sealing component includes a second waterproof sealing ring and a second windproof baffle. The second waterproof sealing ring is sleeved on the second locking component and fits against the hole wall of the second pair of through holes. The second windproof baffle covers the outside of the second pair of through holes and is sealed to the second bracket and the surface of the outer facade.

[0015] In one embodiment, the first bracket includes two first mounting plates, which are respectively disposed on both sides of the window along the width direction of the window and connected to the exterior facade, and the two ends of the first photovoltaic panel are respectively connected to the two first mounting plates;

[0016] The first mounting plate extends vertically, and multiple first photovoltaic panels are provided, with the multiple first photovoltaic panels arranged at intervals along the vertical direction.

[0017] In one embodiment, the second support includes:

[0018] Two third mounting plates are arranged opposite each other and are both connected to the exterior facade;

[0019] The fourth mounting plate is located on the side of the third mounting plate away from the first bracket, and its two ends are respectively connected to the two third mounting plates;

[0020] The fifth mounting plate is arranged parallel to the facade, and its two ends are respectively connected to the two third mounting plates. The fourth mounting plate, the fifth mounting plate, and the two third mounting plates form an accommodating space. The second photovoltaic panel is located on the side of the fifth mounting plate away from the facade.

[0021] In one embodiment, two of the third mounting plates extend in a direction perpendicular to the facade to form mounting supports, and the two ends of the second photovoltaic panel are respectively connected to the two mounting supports.

[0022] In one embodiment, the mounting plate extends vertically, and multiple second photovoltaic panels are provided, with the multiple second photovoltaic panels arranged at intervals along the vertical direction.

[0023] In one embodiment, the angle between the first photovoltaic panel and the vertical direction is 0-5°; and / or,

[0024] The angle between the second photovoltaic panel and the vertical direction is 0-5°.

[0025] In one embodiment, the exterior facade of the building is provided with wiring holes for the wire harnesses of the first photovoltaic panel and / or the second photovoltaic panel to pass through.

[0026] In one embodiment, the first photovoltaic panel is a cadmium telluride photovoltaic panel, and the second photovoltaic panel is a monocrystalline silicon photovoltaic panel.

[0027] The aforementioned multi-functional bracket for prefabricated exterior walls maximizes the use of limited exterior space and avoids equipment stacking conflicts by connecting the first bracket to the exterior facade around the building's windows and placing the second bracket below the first bracket, i.e., the first and second brackets are arranged perpendicularly. A first photovoltaic panel is installed on the first bracket, and a second photovoltaic panel is installed on the second bracket. The first and second photovoltaic panels generate electricity synchronously, further increasing the area covered on the building's exterior facade and fully utilizing the building's solar energy collection potential.

The second photovoltaic panel covers the outer area of ​​the space, utilizing the unused space above the equipment to improve power generation efficiency per unit area. In addition, the first photovoltaic panel can act as a "shading component," reducing direct sunlight entering the room during summer and lowering the air conditioning cooling load.

[0046] This application provides a multi-functional bracket for prefabricated exterior wall decoration, such as... Figure 1 and Figure 2 As shown, the multi-functional bracket for prefabricated exterior wall decoration, used for installation on the exterior facade 800 of a building, includes: a first bracket 100, a first photovoltaic panel 200, a second bracket 300, and a second photovoltaic panel 400. The first bracket 100 is used to connect to the exterior facade 800; the first photovoltaic panel 200 is mounted on the first bracket 100 and can be positioned opposite to a window on the exterior facade 800, and the light transmittance of the first photovoltaic panel 200 is greater than or equal to 40%; the second bracket 300 is used to connect to the exterior facade 800 and is located below the first bracket 100, and the second bracket 300 has a receiving space; the second photovoltaic panel 400 is located on the side of the second bracket 300 facing away from the exterior facade 800.

[0047] The aforementioned multi-functional bracket for prefabricated exterior walls utilizes a first bracket 100 connected to the exterior facade 800 around the building windows, with a second bracket 300 positioned below the first bracket 100. This perpendicular arrangement of the first and second brackets maximizes the use of the limited space on the facade 800 and avoids equipment stacking conflicts. A first photovoltaic panel 200 is installed on the first bracket 100, and a second photovoltaic panel 400 is installed on the second bracket 300. The first and second photovoltaic panels generate electricity synchronously, further increasing the coverage area on the building facade 800 and fully leveraging its solar energy collection potential.

[0048] Furthermore, the first photovoltaic panel 200 is positioned on the outside of the window, and its light transmittance is greater than or equal to 40%, balancing indoor lighting with power generation in low-light environments. The second photovoltaic panel 400 covers the outer area of ​​the space, utilizing the unused space above the equipment to improve power generation efficiency per unit area. In addition, the first photovoltaic panel 200 can also serve as a "shading component," reducing direct sunlight entering the room during summer and lowering the air conditioning cooling load.

[0049] In this embodiment, the first photovoltaic panel 200 is a cadmium telluride photovoltaic panel, and the second photovoltaic panel 400 is a monocrystalline silicon photovoltaic panel.

[0050] A cadmium telluride (CdTe) photovoltaic panel is a thin-film solar cell panel with cadmium telluride (CdTe) as its core light-absorbing layer. Its basic structure is usually formed by the sequential deposition of multiple thin films, including a glass substrate, a transparent conductive oxide layer, a cadmium sulfide buffer layer, a cadmium telluride absorption layer, and a back contact layer. It converts solar energy into electrical energy through the photoelectric conversion principle.

[0051] A monocrystalline silicon photovoltaic (PV) panel is a solar panel that uses high-purity monocrystalline silicon wafers as its core power-generating material. Its basic structure typically consists of a monocrystalline silicon wafer (as the core layer for light absorption and photoelectric conversion), tempered glass (protective layer), EVA film (encapsulation layer), a backsheet (weather-resistant protective layer), and an aluminum frame (for support and fixation). When sunlight shines on the monocrystalline silicon wafer, photon energy excites electron-hole pairs within the semiconductor material, forming a current under the influence of the PN junction electric field, thus converting light energy into electrical energy.

[0052] In this embodiment, the light transmittance of the first photovoltaic panel 200 is greater than or equal to 40%, which not only meets the lighting requirements of the window area and avoids the indoor light being too dark due to the installation of photovoltaic panels, but also realizes the power generation function through the photovoltaic effect. This solves the problem that traditional monocrystalline silicon photovoltaic panels have no light transmittance and cannot be applied to window areas. It effectively utilizes the space around the window to generate electricity without affecting the normal lighting of the building.

[0053] In one embodiment, the first photovoltaic panel 200 makes an angle of 0-5° with the vertical direction; and / or, the second photovoltaic panel 400 makes an angle of 0-5° with the vertical direction.

[0054] In this embodiment, both the first photovoltaic panel 200 and the second photovoltaic panel 400 are set with a tilt angle of 0-5°. This angle design can receive sunlight more efficiently. Compared with the installation method that is perpendicular to the outer facade 800, it can reduce light reflection, increase the light-receiving area of ​​the photovoltaic panel and the duration of sunlight, thereby improving power generation efficiency. Moreover, the tilt angle setting is conducive to rainwater sliding off the surface of the photovoltaic panel, avoiding the risk of water seepage caused by rainwater accumulation on the panel surface, and reducing the erosion of the photovoltaic panel and the connection parts of the support frame. At the same time, the small tilt angle design reduces the direct impact of wind load on the photovoltaic panel while ensuring power generation efficiency, and improves the overall wind resistance stability of the support frame.

[0055] In one embodiment, the system further includes a first locking member and a first sealing member. A first pair of through holes are provided on the exterior facade 800. The first locking member passes through the first bracket 100 and the first pair of through holes to connect the first bracket 100 and the exterior facade 800. The first sealing member includes a first waterproof sealing ring and a first windproof baffle. The first waterproof sealing ring is fitted onto the first locking member and fits against the hole wall of the first pair of through holes. The first windproof baffle covers the outside of the first pair of through holes and is sealed to the surface of the first bracket 100 and the exterior facade 800.

[0056] By passing the first locking member through the first through hole on the first bracket 100 and the exterior facade 800, the first bracket 100 and the exterior facade 800 are fixed together. Compared with the traditional method of fixing to the exterior wall surface only by bolts, this method greatly enhances the connection strength between the first bracket 100 and the building structure, effectively resists the risk of loosening caused by wind and rain erosion and external impact, and structurally reduces the risk of the bracket and the first photovoltaic panel 200 falling off.

[0057] Moreover, the first waterproof sealing ring of the first sealing component is fitted onto the first locking component and fits against the wall of the first pair of perforations, which can effectively prevent rainwater from seeping into the interior of the wall through the perforations, thus avoiding dampness and structural damage to the wall. The first windproof baffle covers the outside of the first pair of perforations and is sealed to the surface of the first bracket 100 and the exterior facade 800, which can reduce the impact of strong winds entering the room through the perforations or directly impacting the connection parts of the bracket, further improving the sealing and wind resistance of the bracket installation part, and ensuring that the interior environment of the building is not affected by the external climate.

[0058] In one embodiment, such as Figure 1 and Figure 2As shown, it also includes a second locking member 500 and a second sealing member 510. A second pair of through holes are provided on the outer facade 800. The second locking member 500 passes through the second bracket 300 and the second pair of through holes to connect the second bracket 300 and the outer facade 800. The second sealing member 510 includes a second waterproof sealing ring and a second windproof baffle. The second waterproof sealing ring is sleeved on the second locking member 500 and fits against the hole wall of the second pair of through holes. The second windproof baffle covers the outside of the second pair of through holes and is sealed to the surface of the second bracket 300 and the outer facade 800.

[0059] By passing the second locking member 500 through the second through hole on the second bracket 300 and the facade 800, the second bracket 300 and the facade 800 are fixed together. Compared with the traditional method of fixing only by surface bolts, the connection strength between the second bracket 300 and the building structure is greatly improved. It can effectively resist the risk of loosening caused by the weight of objects in the space, wind and rain impact, vibration, etc., fundamentally reducing the risk of the second bracket 300 falling off and ensuring the safety of the building facade 800 and the environment below.

[0060] Furthermore, the second waterproof sealing ring of the second sealing component 510 is fitted onto the second locking component 500 and fits against the wall of the second pair of perforations, which can strictly prevent rainwater from seeping into the interior of the wall through the perforations, thus preventing the wall from becoming damp, moldy, or structurally damaged. The second windproof baffle covers the outside of the second pair of perforations and is sealed to the surface of the second bracket 300 and the exterior facade 800, which can reduce the impact of strong winds passing through the perforations on the indoor environment, while reducing the direct impact of wind loads on the connection parts of the brackets, further enhancing the sealing and wind resistance of the installation parts and maintaining the stability of the building structure.

[0061] In one embodiment, such as Figure 1 and Figure 2 As shown, the first bracket 100 includes two first mounting plates 110, which are respectively located on both sides of the window along the width of the window and connected to the exterior facade 800. The two ends of the first photovoltaic panel 200 are respectively connected to the two first mounting plates 110. The first mounting plates 110 extend in the vertical direction, and multiple first photovoltaic panels 200 are provided, which are arranged at intervals in the vertical direction.

[0062] The two first mounting plates 110 of the first bracket 100 are respectively located on both sides of the window along its width and connected to the exterior facade 800, providing a symmetrical and stable support structure for the first photovoltaic panel 200. This ensures that the photovoltaic panel is subjected to balanced forces at both ends, reducing the risk of shaking or falling off due to unstable installation, and is especially effective against the impact of external environments such as wind and rain. The first mounting plates 110 extend vertically, and multiple first photovoltaic panels 200 are arranged at intervals along the vertical direction, making full use of the facade space around the window. This solves the problem of traditional photovoltaic panels being difficult to lay reasonably in the window area, increasing the area covered by the photovoltaic panels and improving power generation efficiency without affecting the normal use of the window.

[0063] In this embodiment, as Figure 1 and Figure 2 As shown, the first bracket 100 also includes a second mounting plate 120, which connects the two first mounting plates 110, thereby improving the connection stability of the two first mounting plates 110 and improving the structural stability of the first bracket 100.

[0064] In one embodiment, such as Figure 1 and Figure 2 As shown, the second support 300 includes:

[0065] Two third mounting plates 310 are arranged opposite each other and are both connected to the exterior facade 800.

[0066] The fourth mounting plate 320 is located on the side of the third mounting plate 310 away from the first bracket 100, and its two ends are respectively connected to the two third mounting plates 310;

[0067] The fifth mounting plate 330 is set parallel to the facade 800, and its two ends are respectively connected to the two third mounting plates 310. The fourth mounting plate 320, the fifth mounting plate 330 and the two third mounting plates 310 form an accommodating space. The second photovoltaic panel 400 is located on the side of the fifth mounting plate 330 away from the facade 800.

[0068] Two opposing third mounting plates 310 connect to the exterior facade 800, providing a symmetrical and stable support foundation for the entire second bracket 300. The fourth mounting plate 320 and the fifth mounting plate 330, together with the two third mounting plates 310, form a receiving cavity, creating a stable frame structure. This allows the weight of objects within the receiving space and the load of the photovoltaic panels to be evenly transferred to the building facade 800 through the frame, preventing excessive localized stress that could lead to bracket deformation or wall damage. A second photovoltaic panel 400 is installed on the side of the fifth mounting plate 330 of the second bracket 300 facing away from the exterior facade 800. This gives the second bracket 300 the dual function of fixing and receiving objects and installing photovoltaic panels, eliminating the need for a separate bracket for the photovoltaic panels, saving exterior wall space, and improving the utilization rate of the building facade 800.

[0069] In some embodiments, the accommodating space is used to accommodate an air conditioner outdoor unit; in other embodiments, the accommodating space may also accommodate other objects as needed by the user.

[0070] In one embodiment, such as Figure 1 and Figure 2 As shown, two third mounting plates 310 extend in a direction perpendicular to the exterior facade 800 to form mounting brackets 340, and the two ends of the second photovoltaic panel 400 are respectively connected to the two mounting brackets 340. The two third mounting plates 310 extending in a direction perpendicular to the exterior facade 800 to form mounting brackets 340 provide an independent and symmetrical support structure for the second photovoltaic panel 400, so that the forces on both ends of the photovoltaic panel are balanced, which can effectively resist loosening or displacement caused by external factors such as wind and rain impact and vibration, and ensure that the photovoltaic panel is firmly installed. The extension direction of the mounting brackets 340 forms a reasonable distance from the exterior facade 800, which not only avoids the shading or heat dissipation problems that may be caused by direct contact between the photovoltaic panel and the exterior facade 800, but also provides suitable installation space for the second photovoltaic panel 400, enabling it to be efficiently laid in areas such as under windows.

[0071] Moreover, the integrated design of the mounting plate 340 and the third mounting plate 310 eliminates the need for additional photovoltaic panel brackets, allowing the second bracket 300 to be combined with the photovoltaic panel support structure. This not only fulfills the function of installing the outdoor unit of the air conditioner but also makes full use of the exterior wall space, avoiding the space waste and structural clutter caused by traditional separate bracket installations.

[0072] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting plate 340 extends vertically, and multiple second photovoltaic panels 400 are arranged at intervals along the vertical direction. The vertical extension of the mounting plate 340 and the intervals between the multiple second photovoltaic panels 400 fully utilize the facade space below the window. Compared to the limitations of traditional photovoltaic panel installation methods in the area below windows, this arrangement maximizes the number and area of ​​second photovoltaic panels 400 without affecting window use or building function, thereby increasing total power generation. Furthermore, the intervals between the multiple photovoltaic panels on the mounting plate 340 ensure stable support at both ends of each panel, resulting in balanced stress distribution.

[0073] In one embodiment, such as Figure 1 and Figure 2As shown, a wiring hole 600 is provided on the building's exterior facade 800. The wiring hole 600 is used for the passage of the wiring harnesses of the first photovoltaic panel 200 and / or the second photovoltaic panel 400. The wiring hole 600 on the exterior facade 800 provides a dedicated passage for the wiring harnesses of the first photovoltaic panel 200 and the second photovoltaic panel 400, avoiding the wiring harnesses being exposed or tangled, reducing the risk of line damage and short circuits caused by wind and rain erosion and external pulling, and also reducing the wear and tear of the wiring on the support structure or the building facade 800, ensuring the safe and stable operation of the power generation system.

[0074] In one embodiment, such as Figure 1 and Figure 2 As shown, a battery 700 is installed inside the building, and is electrically connected to the battery 700 through a wiring harness via a wiring hole 600. The wiring hole 600 provides an adaptation path for the connection between the photovoltaic power generation system and indoor energy storage devices (such as the battery 700), ensuring that the generated electricity can be efficiently and safely transmitted to the energy storage device, realizing a smooth connection between the "power generation-energy storage" link, and helping to maximize the overall efficiency of the multi-functional integrated bracket (power generation, air conditioner outdoor unit fixing, etc.).

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
