Description

Technical Field

[0001] The utility model relates to the technical field of noise control, and in particular to a replaceable photovoltaic sound barrier device. Background Art

[0002] A large number of roofs and walls of sound barriers in cities can be used as resource carriers for photovoltaic power generation. Combining sound barriers with photovoltaics can achieve sound insulation and noise reduction while generating green electricity.

[0003] Traditional plug-in sound barriers are usually installed by inserting them directly from the top of the main steel structure or inserting them from the inside of the steel frame. The problems they have are:

[0004] (1) Material replacement is difficult: The design service life of the general sound barrier structure is 50 years, while the design service life of the sound barrier panels and internal sound-absorbing and insulating materials is 25 years. The traditional plug-in sound barrier is vertically interlocked, and the gravity load is transmitted between the panels. When the sound barrier material reaches its service life or is damaged for other reasons and needs to be repaired and replaced, the sound barrier panels must be completely removed from the inside of the H-shaped steel. It is impossible to independently remove and replace one of the sound barrier panels. For fully enclosed plug-in sound barriers, some structural components need to be removed, and replacement and installation require a large amount of internal space. For subways, railways, high-speed railways and other long-term energized working conditions, it affects the normal operation of the line and poses a great risk. It is a time-consuming, labor-intensive and dangerous project.

[0005] (2) Relatively simple functionality: Traditional plug-in sound barriers are only used as noise reduction and sound insulation designs, with relatively simple functions. There is a large amount of waste of space resources on the walls and roofs.

[0006] (3) Inconvenient installation: Traditional plug-in sound barriers require construction on the inner side of the line, which requires cross-operation with other professionals, affecting the construction progress; if the overlap between the sound barrier unit plate and the main steel structure is insufficient, there may be a risk of the unit plate falling to the inside of the line.

[0007] (4) Poor overall landscape: The traditional plug-in type sound barrier is discontinuous and discontinuous at the steel structure position, and the main steel structure is exposed, making it difficult to achieve a good landscape effect.

[0008] Therefore, it is necessary to study a new type of sound barrier device that can solve the problem of difficulty in later operation, maintenance and replacement while achieving the goal of sound insulation and noise reduction, make full use of idle space resources, and improve the city's landscape requirements. Utility Model Content

[0009] In response to the problem that existing plug-in sound barriers are difficult to operate, maintain and replace, the utility model provides a replaceable photovoltaic sound barrier device. Both the sound barrier panels and photovoltaic panels can be installed and replaced independently, which can ensure the realization of the sound insulation, noise reduction and power generation goals throughout the life cycle of the building.

[0010] The utility model adopts the following technical solutions:

[0011] A replaceable photovoltaic sound barrier device comprises a main steel structure, a sound barrier unit panel and a photovoltaic panel, wherein the sound barrier unit panel is installed on the main steel structure, and the photovoltaic panel is installed on the sound barrier unit panel.

A lug is formed at each end of the sound barrier unit panel, and the inner side of the lug contacts the outer side of the wing panel of the main steel structure; a through-connector is pre-embedded on the sound barrier unit panel, and a photovoltaic keel connected to the through-connector is installed on the outside thereof, and the sound barrier supports on both sides of the web are respectively fixedly connected to the corresponding sound barrier unit panels through the through-connector, and the lugs on the two adjacent sound barrier unit panels form a vertical butt joint on the wing panel, and a seal is provided in the butt joint, and the photovoltaic panel is installed on the photovoltaic keel.

[0012] Preferably, the sound barrier unit panel includes a perforated panel, a decorative outer panel and a sound-absorbing material, the ends of the sound-absorbing material are respectively covered with keels, the perforated panel is installed on one side of the sound-absorbing material, and the decorative outer panel is installed on the other side of the sound-absorbing material. The decorative outer panel extends to both sides of the left and right ends of the sound-absorbing material to form the lugs, the decorative outer panel and the perforated panel are fixedly connected to the keel through a connecting piece, and the through-connecting piece passes through the perforated panel, keel, sound-absorbing material and decorative outer panel and is fixedly connected to the photovoltaic keel.

[0013] Preferably, the seal comprises a foam rod and a weatherproof sealant filled in the joint.

[0014] Furthermore, a rubber pad is provided between the sound barrier support and the perforated panel of the sound barrier unit plate.

[0015] Preferably, a bolt clamp is provided on the photovoltaic keel, and the end of the photovoltaic panel is screwed to the bolt clamp via a Z-shaped support.

[0016] Preferably, the perforated panel is a galvanized steel plate or a rust-proof aluminum alloy plate, and the perforations thereon are in the form of one or more of pinholes, round holes, and louver holes.

[0017] Preferably, the sound absorbing material is one or more porous materials selected from rock wool, glass wool, foamed aluminum, polyester fiber, and polyurethane foam.

[0018] The technical solution of this utility model has the following advantages:

[0019] A. Compared with the existing traditional plug-in sound barrier, this utility model solves the problem of later maintenance and replacement of sound barriers by changing the force transmission direction and installation method of the sound barrier panels. Especially for the normally operating rail transit system, it can ensure the safe and efficient iterative replacement of sound barrier panels throughout the life cycle of the main structure, ensuring the normal sound insulation and noise reduction effect of the line.

Since the photovoltaic panels can be disassembled and replaced normally, it will not affect the normal function of the sound barrier device.

[0021] C. This utility model combines photovoltaics with a sound barrier, providing sound insulation and noise reduction on the inside while generating photovoltaic power on the outside. The photovoltaic panel mounting keels are bolted to the internal keels of the sound barrier, allowing for independent replacement and installation of the panels. A clear space between the panels and the sound barrier ensures proper heat dissipation during power generation and provides space for wiring installation.

[0022] D. The utility model achieves the effect of not exposing the main steel structure by extending the decorative outer panel of the sound barrier unit panel, ensuring the overall continuity of the external landscape of the sound barrier, and being able to meet the high-standard landscape design requirements of urban sound barriers. At the same time, it protects the main steel structure and improves the corrosion resistance of the main steel structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1 and Figure 2As shown, the utility model provides a replaceable photovoltaic sound barrier device, including a main steel structure 1, a sound barrier unit panel 2 and a photovoltaic panel 3. The sound barrier unit panel 2 is installed on the main steel structure 1, and the photovoltaic panel 3 is installed on the sound barrier unit panel 2. Sound barrier supports 4 are symmetrically installed on both sides of the web 11 of the main steel structure 1. The sound barrier supports 4 are arranged perpendicular to the web 11, and they adopt fixed angle steels. A fixed angle steel is arranged on each side of the web 11, and the two angle steels are fixedly connected to the web through a connecting piece 8. A lug 221 is formed on the left and right ends of the sound barrier unit panel 2, respectively. The inner side of the lug 221 contacts the outer side of the wing plate 12 of the main steel structure 1. A through connector 5 is pre-embedded on the sound barrier unit panel 2, and a photovoltaic keel 6 connected to the through connector 5 is installed on its outer side. The sound barrier supports 4 on both sides of the web 11 are respectively fixedly connected to the corresponding sound barrier unit panels 2 through the through connector 5. The lugs 221 on the two adjacent sound barrier unit panels 2 form a vertical joint a on the wing plate 12. A seal 7 is provided in the joint, and the photovoltaic panel 3 is installed on the photovoltaic keel 6. The sound barrier unit panel in the present invention is provided with a lug structure. The lug structure on the two adjacent sound barrier unit panels completely blocks the exposed part of the main steel structure, achieving the effect of the main steel structure not being exposed, ensuring the overall continuity of the external landscape of the sound barrier, and meeting the high-standard landscape design requirements of urban sound barriers.

[0040] At the same time, the photovoltaic panels are connected to the sound barrier unit panels through photovoltaic keels and are arranged on the outside of the sound barrier panels, forming a certain gap between the two. The power generation characteristics of the photovoltaic panels are fully considered, and sufficient space is reserved between the photovoltaic panels and the sound barrier panels to facilitate the diffusion of heat when the photovoltaic panels are working, and also provide space for the laying and connection of photovoltaic lines. The utility model integrates the photovoltaic power generation system into the sound barrier, enriches the functions of the sound barrier, makes full use of the idle space resources of the sound barrier, provides green electricity supply for urban construction, and increases the efficiency of the operating system companies. At the same time, the photovoltaic keel and the sound barrier unit panels adopt a detachable connection method, so that the photovoltaic panels can be normally disassembled and replaced without affecting the normal function of the sound barrier device.

[0041] The sound barrier unit panel 2 includes a perforated panel 21, a decorative outer panel 22 and a sound-absorbing material 23. The ends of the sound-absorbing material 23 are respectively covered with keels 24. The perforated panel 21 is installed on one side of the sound-absorbing material 23, and the decorative outer panel 22 is installed on the other side of the sound-absorbing material 23. The decorative outer panel 22 extends to both sides of the left and right ends of the sound-absorbing material 23 to form lugs 221. The decorative outer panel 22 and the perforated panel 21 are fixedly connected to the keel 24 through the connecting piece 8, and the through-connecting piece 5 passes through the perforated panel 21, the keel 24, the sound-absorbing material 23 and the decorative outer panel 22 and is fixedly connected to the photovoltaic keel 6.

[0042] The seal 7 includes a foam rod 71 and a weather-resistant sealant 72 filled in the joint a. The perforated panel 21 can be made of galvanized steel plate or rust-proof aluminum alloy plate (the perforation form is pinhole, round hole, louver hole, etc.). The sound-absorbing material 23 can be made of a variety of porous materials such as rock wool, glass wool, foam aluminum, polyester fiber, polyurethane foam, etc. The keel 24 is made of galvanized steel keel and is formed by welding connection. Its own strength should be able to meet the structural force requirements. The through connector 5 can adopt a bolt structure, which serves as the main force transmission component of the sound barrier unit plate. It is fixed on the galvanized steel keel by reliable welding, which is convenient for on-site installation. It is also a significant feature of the present invention that distinguishes it from traditional sound barrier devices.

[0043] At the same time, reliable anti-corrosion measures should be taken at the welding points between the galvanized steel keels and the embedded through-connectors 5 to meet the durability requirements of the sound barrier.

[0044] The present invention also provides a rubber pad 20 between the sound barrier support 4 and the perforated panel 21 of the sound barrier unit plate 2, preferably an EPDM rubber pad, as a buffering and vibration-reducing component, which is fixed at the connection position between the sound barrier unit plate and the main steel structure or movable connecting part to avoid hard connection of the sound barrier unit plate to generate secondary noise.

[0045] The various materials in the sound barrier unit panel body are connected and fixed by rivets. The material of the rivets can be selected from open-type blind aluminum rivets, closed-type aluminum rivets, stainless steel rivets and color-coated rivets as needed.

[0046] In addition, a bolt clamp 9 is provided on the photovoltaic keel 6 , and the end of the photovoltaic panel 3 is screwed to the bolt clamp 9 through a Z-shaped support 10 .

[0047] Among the connecting materials, the sound barrier supports 4 and the main steel structure 1 are the primary force-transmitting components of this utility model, and their strength must meet the structural load requirements. The form of the main steel structure 1 is determined by the structural design, and the cross-section can be H-shaped, square tube, round tube, etc. The main steel structure can be cantilevered, gate-shaped, circular, elliptical, and other forms. The sound barrier device can be enclosed and can be upright, semi-enclosed, or fully enclosed. The design can be based on the requirements of the environmental impact assessment report or the actual needs of the project.

[0048] The foam rod 71 and weather-resistant sealant 72 used in the present invention are decorative designs adopted to enhance the landscape effect of the device of the present invention and can also improve the waterproof ability of the device of the present invention. Whether to use them can be decided based on the actual situation of the project.

[0049] In the photovoltaic material, the photovoltaic keel 6 is a cold-bent galvanized keel, and the bolt clip 9 is a sliding component customized in the photovoltaic keel 6, which is fixed according to the designed fixed spacing. The clip fixing bolt 30 fixes the support 10 on the photovoltaic keel 6, and the photovoltaic panel 3 is embedded through the support 10.

[0050] In addition, the cavity between the photovoltaic panel 3 and the sound barrier unit panel 2 is open, which facilitates the diffusion of heat when the photovoltaic panel 3 is working, and also provides space for the laying and connection of photovoltaic lines.

[0051] The utility model changes the force-bearing mode of the sound barrier unit panels. Each sound barrier unit panel is independently fixed and force is transmitted by bolts. The gravity load of the upper and lower panels is not transmitted. Secondly, the installation mode of the sound barrier panels is changed from a plug-in type to an external hanging type, so that the sound barrier can be installed from the outside of the structure, without occupying the internal usable space and without affecting the installation of the internal structure, thereby realizing the convenience of replacing and installing the sound barrier panels.

[0052] Any matters not described in the present invention are applicable to the prior art.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
