Description

Technical Field

[0001] The utility model relates to the technical field of rail transit facilities, and particularly to an integrated photovoltaic composite sound absorption and insulation unit board. Background Technique

[0002] The rapid development of modern cities has brought serious noise pollution problems. A large amount of noise generated by means of transportation, industrial equipment, and various construction activities has had a negative impact on the quality of life and health of residents. Therefore, how to effectively reduce urban noise has become an urgent problem to be solved. At the same time, with the intensification of the global energy crisis and the improvement of environmental protection awareness, the development and utilization of renewable energy have received increasing attention. As a clean energy technology, photovoltaic technology can convert solar energy into electrical energy and provide energy support for buildings and urban infrastructure.

[0003] Materials with single functions have been difficult to meet the needs of modern architecture and urban governance. The development trend of multi-functional composite materials is becoming increasingly obvious. By compounding materials with different functions, not only can the utilization efficiency of materials be improved, but also the use of one material for multiple purposes can be realized, saving resources and costs. Driven by green buildings and energy-saving buildings, traditional building materials are gradually developing towards functional diversification, energy conservation, and environmental protection. Composite materials that combine sound absorption functions with photovoltaic power generation functions can not only reduce building energy consumption but also improve the acoustic environment.

[0004] At present, the construction technology of photovoltaic sound barriers on rail transit and other lines generally adopts the "post-attached installation" process, that is, an additional installation technology of photovoltaic panels based on the existing sound barrier structure to achieve the dual functions of noise reduction and power generation on subway lines. From the preliminary design to the intermediate production and the subsequent construction and installation, this process not only requires a secondary design review of the attached structure of the post-installed photovoltaic panels, such as whether the load conditions and structural forms meet the installation conditions of the photovoltaic panels, resulting in many limiting factors; moreover, the size of the sound barrier structure restricts the standardized production of photovoltaic panels and cannot form a mass production scale, thereby increasing the design, production, and construction costs; in addition, the attached post-installed photovoltaic sound barrier is only simply combined by means of bolts, rivets, or structural adhesives, and its overall structural stability and safety are relatively poor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 、 Figure 2 and Figures 7 to 10 A one-piece photovoltaic composite sound absorption and insulation unit board may include two symmetrically distributed special-shaped supports 10, several connecting pieces 20, a photovoltaic panel 30, a microporous panel 40, two E-shaped supports 50, several C-shaped supports 60, and a sound absorption layer 80. One side of the two special-shaped supports 10 facing the steel beam 90 and the side facing away from the steel beam 90 during installation are respectively set as side A and side B, and side A is the sound wave contact side, and side B is the photovoltaic power generation side. The B sides of the two special-shaped supports 10 can be used to install and fix the photovoltaic panel 30 by means of several connecting pieces 20, while on the A sides of the two special-shaped supports 10, the microporous panel 40 can be installed and fixed by means of several connecting pieces 20. The photovoltaic panel 30 and the microporous panel 40 can be fixed by means of vertical installation or arc installation according to the placement area required for the one-piece photovoltaic composite sound absorption and insulation unit board in advance. The two E-shaped supports 50 are respectively buckled and fixed at the two open ends of the surrounding structure of the two special-shaped supports 10, the photovoltaic panel 30, and the microporous panel 40, and a cavity structure 70 can be formed in the surrounding structure of the two special-shaped supports 10, the photovoltaic panel 30, the microporous panel 40, and the two E-shaped supports 50. Several C-shaped supports 60 are arranged on the side of the cavity structure 70 close to the photovoltaic panel 30, and several C-shaped supports 60 are installed and fixed between the two E-shaped supports 50. The C-shaped supports 60 can assist in the installation and fixation of the photovoltaic panel 30 by means of connecting pieces 20. The sound absorption layer 80 made of sound absorption material is filled and arranged on the side of the cavity structure 70 close to the microporous panel 40, and can consume sound wave energy in cooperation with the microporous panel 40 and the natural cavity in the cavity structure 70 to improve the noise reduction effect. In addition, the photovoltaic panel 30 is used to replace the aluminum alloy back panel of the original metal sound absorption and insulation unit board, so that it can also have certain sound insulation and flame retardant effects.

[0032] Refer to Figure 6 The special-shaped support 10 includes a U-shaped section and an L-shaped section, and the opening of the U-shaped section is connected to the long side of the L-shaped section to form an integral structure. Through special shape and strength design, the special-shaped support 10 provides top and bottom skeleton support and sealing plate functions during the production and installation of the one-piece photovoltaic composite sound absorption and insulation unit board, providing a prerequisite for installation convenience and overall appearance coordination.

[0033] Refer to Figure 3 and Figure 4 , the E-shaped support 50 provides the functions of a side support framework and a sealing plate. Its double-groove design provides a reasonable distribution for the arrangement of the sound absorption layer 80 and the photovoltaic panel 30, and naturally forms a noise reduction cavity structure, which increases the overall stability while enhancing the noise reduction effect.

[0034] Refer to Figure 5 , the C-shaped support 60 can provide the framework support for the mechanical connection and chemical connection of the photovoltaic panel 30, and can increase the stability of the prefabricated installation of the photovoltaic panel 30.

[0035] In this embodiment, the material of the microporous panel 40 itself is an aluminum alloy plate, which gives it good corrosion resistance, and a fluorocarbon spraying treatment is carried out on the surface of the microporous panel 40, so that its surface has a fluorocarbon coating, further enhancing the anti-corrosion ability. The aperture of the micropores on the surface of the microporous panel 40 is ≤2.5 mm, and the perforation rate is 20%-30%. In addition, a number of pre-set bolts 41 are fixedly connected in advance on the side of the microporous panel 40 facing the steel beam 90. When the integrated photovoltaic composite sound absorption and insulation unit board is installed and fixed at the steel beam 90, the pre-set bolts 41 can be passed through the fixing clips 91 installed on the side of the steel beam 90 and tightened with nuts to complete the installation. And when the integrated photovoltaic composite sound absorption and insulation unit board is installed and fixed at the steel beam 90, the stepped part on the outside of the special-shaped support 10 can be abutted against the steel beam 90 for positioning installation.

[0036] In this embodiment, the sound absorption layer 80 can adopt a sound absorption material in the prior art that meets the design requirements of the sound absorption coefficient, is moisture-proof, and has a combustion rating of B1 or above.

[0037] The integrated photovoltaic composite sound absorption and insulation unit board can be designed, constructed and installed simultaneously with the main frame structure. Combining the cross-section characteristics of the sound barrier steel frame, the structure form of the photovoltaic sound absorption and insulation unit board is further optimized to achieve convenient installation, eliminate process constraints, and realize the integrated installation of the photovoltaic composite sound absorption and insulation unit board. And combined with the design of the pre-set bolts, the limitation of the traditional plug-in installation process is removed, and the photovoltaic sound absorption and insulation unit board can be conveniently installed from the outside of the steel structure frame. At the same time, the new structure form has achieved a breakthrough in terms of the overall appearance integrity and aesthetics.

[0038] On the B side of the integrated photovoltaic composite sound absorption and insulation unit board, through reasonable arrangement of the photovoltaic panels, the splicing joints of the steel structure frame exposed on the building outer surface can be covered. While meeting the functions of sound absorption and power generation, the external photovoltaic panels and the main structure and other parts are deeply integrated. Through customized design, photovoltaic panels of various colors and shapes can be realized, enhancing the visual effect of the building and improving the aesthetics of the building. On its A side, while absorbing sound, through the cavity structure between the A and B sides, the sound wave energy can be further consumed, increasing the noise reduction effect.

[0039] The integrated photovoltaic composite sound-absorbing and sound-insulating unit board can be used not only in the field of traffic infrastructure sound barriers, but also in industrial plants, residential buildings, public buildings and other scenes. It has a wide range of application prospects and can bring significant economic and environmental benefits. In addition, it can also realize the installation of vertical and curved structures, and can be applied to various types of sound barrier structures, including residential buildings, commercial buildings, industrial plants, etc., without being restricted by building types and structures.

[0040] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
