Description

Technical Field

[0001] The utility model relates to the technical field of integrated exterior wall panels, in particular to a solar thermal integrated exterior wall panel device for green buildings. Background Art

[0002] From an architectural perspective, integrated exterior wall panels are a construction method to achieve decorative or indoor insulation effects. From a product perspective, integrated exterior wall panels are a type of building material, which are building panels used for exterior walls. Integrated exterior wall panels must have basic properties such as corrosion resistance, high temperature resistance, aging resistance, no radiation, fire resistance, insect resistance, and non-deformation. At the same time, they are also required to have beautiful appearance, simple construction, environmental protection and energy saving. Common integrated exterior wall panels include fiber cement boards, aluminum-plastic boards, PVC boards, stone, etc.

[0003] At present, the Chinese utility model with the announcement number: CN219863430U discloses a photovoltaic insulation integrated exterior wall panel. This utility model relates to the technical field of integrated exterior wall panels and discloses a photovoltaic insulation integrated exterior wall panel, including a prefabricated exterior wall panel, an insulation panel and multiple groups of solar panels. One side of the prefabricated exterior wall panel is integrally formed with multiple groups of positioning screws. Through the cooperation between the positioning screws, the positioning assembly and the solar panel, the solar panels are mutually clamped and fixedly connected to the positioning screws through the positioning assembly, which improves the overall installation stability of the solar panel, makes the solar panel fit tightly with the insulation layer, reduces the porosity, and thus avoids the solar panel from falling off when the wind is strong. The positioning assembly is doubly protected by the hexagonal nut and the limit screw sleeve, and the integrity of the solar panel is realized through the connecting assembly, thereby improving the overall stability, low cost, simple and convenient installation, and convenient for replacing the solar photovoltaic panel separately, which increases practicality.

[0004] According to the above patent, in the actual installation process of the existing photovoltaic insulation integrated exterior wall panels, the solar panels are clamped together, and then the positioning screws are fixedly connected through the positioning components. Since the solar panels need to be frequently fixed with bolts during the installation process, although this method can ensure the stability of the connection, the excessive bolt operation steps are cumbersome, including aligning the screw holes, tightening the bolts, etc., which will consume more time and manpower, thereby reducing the installation efficiency. Especially in the large-scale installation of exterior wall panels, the low installation efficiency may affect the progress of the entire project, increase the construction cost, and is not conducive to the wide application and promotion of the product in actual construction projects. Therefore, a solar thermal integrated exterior wall panel device for green buildings is proposed to solve the above-mentioned problems. Utility Model Content

[0030] The utility model provides a solar thermal integrated exterior wall panel device for green buildings, which aims to solve the problem that in the actual installation process of the existing photovoltaic thermal insulation integrated exterior wall panels, the solar panels are clamped together and then fixedly connected by positioning screws through positioning components. Since the solar panels need to be frequently fixed with bolts during the installation process, although this method can ensure the stability of the connection, the excessive bolt operation steps are cumbersome, including aligning the screw holes, tightening the bolts, etc., which will consume more time and manpower, thereby reducing the installation efficiency. Especially in the large-scale installation of exterior wall panels, the low installation efficiency may affect the progress of the entire project, increase construction costs, and be detrimental to the wide application and promotion of the product in actual construction projects.

[0031] like Figure 1-7 As shown, an embodiment of the present invention provides a solar thermal integrated exterior wall panel device for a green building, comprising an exterior wall panel 1, an insulation panel 2 is provided inside the exterior wall panel 1, a limiting mechanism 3 is provided on the top and bottom of the exterior wall panel 1, a solar photovoltaic panel 4 is provided on the front side of the insulation panel 2, and the solar photovoltaic panel 4 is located on the inner side of the limiting mechanism 3;

[0032] The limiting mechanism 3 includes a connecting plate 301 arranged at the top and bottom of the exterior wall panel 1, and a positioning bolt 302 is provided on the outer side of the connecting plate 301. The inner side of the positioning bolt 302 passes through the outer side of the connecting plate 301 and is threadedly connected to the outer side of the exterior wall panel 1. The front side of the connecting plate 301 is fixedly connected to a baffle 303, and the baffle 303 is located on the outer side of the solar photovoltaic panel 4. A positioning structure 304 is provided on the inner side of the baffle 303, and the inner side of the positioning structure 304 is in contact with the outer side of the solar photovoltaic panel 4.

[0033] In the technical solution of the present invention, by setting a limiting mechanism 3, during the installation process, the thermal insulation board 2 is first installed inside the exterior wall panel 1 to provide basic thermal insulation performance for the building, and then the solar photovoltaic panel 4 is installed, which is placed on the front side of the exterior wall panel 1 and located on the inside of the limiting mechanism 3. The connecting plate 301 is threadedly connected to the exterior wall panel 1 through the positioning bolt 302 on the connecting plate 301 of the limiting mechanism 3, so as to quickly achieve preliminary positioning. At this time, the baffle 303 fixed on the front side of the connecting plate 301 is located on the outside of the solar photovoltaic panel 4, which plays a role of preliminary blocking and lateral positioning. The positioning structure 304 on the inside of the baffle 303 is connected to the solar photovoltaic panel 4. The outer side of the solar photovoltaic panel 4 is in close contact, which further accurately adjusts the position of the solar photovoltaic panel 4 and provides stable support to limit its displacement and ensure its stable installation. During use, the solar photovoltaic panel 4 can effectively absorb solar energy and perform photoelectric conversion. The generated electricity can be used by the building. At the same time, the heat energy generated is effectively blocked by the insulation panel 2 to avoid affecting the internal temperature of the building, realizing the integrated solar thermal function. Moreover, due to the stable fixation of the limiting mechanism 3, the solar photovoltaic panel 4 can remain stable under various environmental conditions, ensuring the continuous and efficient operation of the entire device, providing the building with a stable energy supply and good insulation effect.

[0034] Please refer to Figure 4 The positioning structure 304 includes a threaded rod 3041 threadedly connected to the outside of the baffle 303. A turntable 3042 is fixedly connected to the bottom of the threaded rod 3041. A positioning plate 3043 is rotatably connected to the inner side of the threaded rod 3041. The inner side of the positioning plate 3043 contacts the outer side of the solar photovoltaic panel 4. In this embodiment, by providing the threaded rod 3041, the turntable 3042, and the positioning plate 3043, during installation, the turntable 3042 is rotated by a tool to cause the threaded rod 3041 to rotate on the outer side of the baffle 303. Due to the rotational connection with the positioning plate 3043, the horizontal displacement of the threaded rod 3041 pushes the positioning plate 3043 toward the solar photovoltaic panel 4 until close contact is achieved, achieving precise positioning and fixation. The overall operation is simple, and the position of the positioning plate 3043 can be easily adjusted by the turntable 3042 to accommodate the installation of solar photovoltaic panels 4 of different thicknesses. The positioning is firmly positioned to prevent displacement and shaking during use, ensuring normal operation and long service life.

[0035] For further information, please refer to Figure 5 The solar photovoltaic panels 4 are provided with connection holes 5 on both sides of the top, and connection rods 6 on both sides of the bottom of the solar photovoltaic panels 4. The connection rods 6 are plugged into the connection holes 5. In this embodiment, by providing the connection holes 5 and connection rods 6, during installation, the connection rods 6 at the bottom of one solar photovoltaic panel 4 are inserted into the connection holes 5 at the top of another panel to achieve preliminary vertical positioning and alignment. This simplifies the installation process, improves efficiency, enhances the connection stability of adjacent solar photovoltaic panels 4, and reduces the risk of loosening and misalignment due to external forces.

[0036] Please continue to refer to Figure 6 A magnetic sheet 7 is bolted to the left side of the solar photovoltaic panel 4, and a magnet sheet 8 is bolted to the right side of the solar photovoltaic panel 4. Magnet sheet 8 is magnetically connected to magnetic sheet 7. In this embodiment, by providing magnetic sheet 7 and magnet sheet 8, after the adjacent panels are initially connected through the connecting holes 5 and connecting rods 6, the magnetic attraction between magnetic sheet 7 and magnet sheet 8 allows the solar photovoltaic panel 4 to be tightly fitted in the horizontal direction. This is quick and convenient, improves installation accuracy and stability, cushions external force impact, and reduces the possibility of loose connections.

[0037] Please refer to Figure 6 The left side of the magnetic sheet 7 is provided with a slot 9, and the right side of the magnet sheet 8 is fixedly connected with a clamping block 10. In this embodiment, by providing the slot 9 and the clamping block 10, when splicing, the clamping block 10 of the magnet sheet 8 is clamped into the slot 9 of the magnetic sheet 7, forming a mechanical clamping, providing additional connection protection, preventing the solar photovoltaic panel 4 from separating under large external forces, and enhancing the stability, safety and durability of the system.

[0038] Also, please refer to Figure 7 The insulation panel 2 includes an insulation layer 201 disposed within the exterior wall panel 1, and a waterproof and fireproof layer 202 is disposed on the front side of the insulation layer 201. In this embodiment, by providing the insulation layer 201 and the waterproof and fireproof layer 202, the insulation layer 201 is located within the exterior wall panel 1 to prevent heat conduction, while the waterproof and fireproof layer 202 is located on the front side, thereby preventing water from entering the insulation layer 201 and preventing fire from spreading. This synergistically ensures thermal insulation, reduces energy consumption, improves waterproof and fireproof safety, protects the building structure, and increases user comfort.

[0039] Also, please refer to Figure 7 An isolation layer 203 is provided behind the thermal insulation layer 201, and the interior of the isolation layer 203 is in a vacuum state. In this embodiment, by providing the isolation layer 203, the isolation layer 203 is located behind the thermal insulation layer 201. The vacuum state reduces the heat and sound transmission medium, improves thermal insulation and sound insulation, maintains a constant temperature, reduces temperature and controls energy consumption, and creates a quiet environment.

[0040] Also, please refer to Figure 7 A sealing layer 204 is provided on the rear side of the isolation layer 203, and a wear-resistant reinforcement layer 205 is provided on the rear side of the sealing layer 204. In this embodiment, by providing the sealing layer 204 and the wear-resistant reinforcement layer 205, the sealing layer 204 adheres to the isolation layer 203 to prevent foreign matter from entering and maintain vacuum performance, while the wear-resistant reinforcement layer 205 is exposed to the outside world to withstand wear and impact, protecting the internal structure. The two work together to extend the service life of the exterior wall panel 1 and reduce maintenance costs.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present invention.
