Description

Technical Field

[0001] This utility model relates to the field of road ancillary facilities and their construction, and in particular to a prefabricated intelligent monitoring photovoltaic acoustic barrier. Background Technology

[0002] With the rapid development of transportation infrastructure, traffic noise from highways and railways has severely impacted the lives of residents along the routes, and sound barriers, as a core noise reduction facility, have been widely used. However, existing sound barriers have many shortcomings: First, traditional barriers are mostly rigid integrated structures, requiring large-scale demolition and reconstruction for upgrades, resulting in long construction periods, high costs, traffic disruption, and construction quality easily affected by site conditions; Second, power supply for monitoring equipment in remote sections is difficult, relying on the power grid incurs extremely high wiring costs, and using traditional batteries requires frequent inspections and replacements, leading to a heavy maintenance burden; Third, existing photovoltaic sound barriers are mostly fixed-angle, integrally encapsulated structures, unable to adapt to varying lighting and acoustic requirements, and lack standardized intelligent device interfaces, resulting in a disconnect between power generation and consumption, making it difficult to meet the development needs of smart transportation and green infrastructure. Therefore, there is an urgent need for a sound barrier that integrates rapid assembly, functional customization, energy self-sufficiency, and intelligent monitoring. Utility Model Content

[0003] This invention aims to completely solve a series of systemic problems faced by existing acoustic barriers in their renovation, upgrading, functional expansion, and intelligent application. Specifically, the goal of this invention is to provide a prefabricated intelligent monitoring photovoltaic acoustic barrier that integrates structural innovation, functional modularity, and energy self-sufficiency. Its core objectives are reflected in three aspects: First, at the structural level, it breaks through the limitations of traditional fixed barriers, providing a foldable, quickly assembled support frame to achieve modular construction and renovation, fundamentally solving the pain points of existing technologies such as long construction cycles, significant traffic interference, and difficulty in controlling on-site work quality. Second, at the functional and energy level, it expands the single noise reduction function into a customizable functional platform, integrating photovoltaic power generation and multiple sound-absorbing modules, enabling the barrier not only to control noise but also to become a distributed micro-power station. Simultaneously, excess electricity generated by the photovoltaic panels, stored in built-in lithium batteries, can provide a certain amount of stable energy for facilities in remote areas lacking power supply, achieving a sustainable operation mode. Third, at the level of intelligence, a standardized plug-and-play interface is provided, enabling monitoring equipment for noise, environment, traffic flow, etc., to be quickly deployed and put into operation without complex wiring and power supply engineering, thus promoting the evolution of sound barriers from static isolation facilities to dynamic intelligent sensing nodes.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A prefabricated intelligent monitoring photovoltaic acoustic barrier is characterized by comprising a prefabricated structural frame, functional panels, and monitoring components. The prefabricated structural frame includes at least three frame units, a connecting plate, and a frame support. Multiple frame units are sequentially hinged to achieve folding. The connecting plate is hinged to the top of the frame units, and a monitoring device mounting slot is provided in the middle of the connecting plate. The prefabricated structural frame is fixed to existing or newly built acoustic barrier pillars through positioning bolt holes. The back of the functional panel has a first engaging portion, and the prefabricated structural frame has a corresponding second engaging portion. After being positioned by the first and second engaging portions, the functional panel is fastened to the prefabricated structural frame by bolts. The functional panel includes at least one of a single-glass photovoltaic panel, a double-glass photovoltaic panel, and a sound-absorbing panel. The monitoring components are slidably engaged in the monitoring device mounting slot, and automatically connect to the pre-installed power supply line and signal transmission line within the slot after installation.

[0006] Preferably, the prefabricated structural frame is a lattice frame made of metal in one piece, and the frame unit and the frame support are an integrated structure.

[0007] Preferably, the single-glass photovoltaic panel is a single-sided photovoltaic power generation structure, suitable for installation in existing soundproof barrier areas; the double-glass photovoltaic panel is a double-sided photovoltaic power generation structure, suitable for installation in light-transmitting sound barrier areas; and the sound-absorbing panel is a porous sound-absorbing material structure, suitable for high-noise areas.

[0008] Preferably, both the single-glass photovoltaic panel and the double-glass photovoltaic panel integrate a solar controller and a lithium battery module. The solar controller has a built-in DC-DC charging circuit, which can convert the unstable high-voltage DC power generated by the photovoltaic panel into a charging voltage that is compatible with the lithium battery module, thereby realizing energy storage and power supply during non-power generation periods.

[0009] Preferably, the monitoring device mounting slot is an integrally molded structure, serving as both a handle and a base for mounting the monitoring components; the monitoring components include at least one of an environmental quality monitoring component, a roadside indicator light, and a noise monitoring device.

[0010] The beneficial effects of this utility model are:

[0011] (1) The core foldable frame design of this utility model allows the originally bulky barrier skeleton to be folded up like a folding screen, reducing transportation and storage space by more than 60%, and directly and significantly reducing logistics costs.

[0012] (2) This utility model adopts an assembly-type installation method with snap-fit ​​initial positioning and bolt final tightening. This method simplifies the process, reduces the need for highly skilled workers, and makes the installation process like assembly, shortening the on-site construction time by several times.

[0013] (3) This utility model has a significant effect on upgrading existing sound barriers. This product can be directly installed on the original pillars as a complete functional module without the need for large-scale, long-term civil construction, thus minimizing the interference with existing traffic.

[0014] (4) This utility model provides three core functional modules: single-glass photovoltaic, double-glass photovoltaic, and sound-absorbing panels. Users can select the optimal combination of functional panels for each section of the barrier according to specific needs such as road orientation, sunlight conditions, and noise distribution, for example, strengthening noise reduction on the residential side and focusing on power generation on the non-residential side. This achieves a high degree of customization and optimal resource allocation.

[0015] (5) The integrated photovoltaic panel of this utility model enables the green electricity generated to solve the problem of power supply difficulties for monitoring equipment and indicator lights in remote areas, realizing the self-sufficiency of the equipment. In addition, the surplus electricity can also provide energy for future additional equipment, such as roadside indicator lights and emergency lighting, creating added value.

[0016] (6) The monitoring device mounting slot at the top of this utility model integrates structural support, power transmission, and signal transmission functions. Any monitoring component that meets the interface standard, such as noise, environmental, and traffic flow sensors, can be slid in and automatically connected to power and signal, achieving true plug-and-play functionality. This completely eliminates the complex engineering required for separate wiring and power supply applications for each monitoring point. Attached Figure Description

Detailed Implementation

[0026] 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, not all embodiments. This embodiment shows the effect of installing all modules, not the only combination scheme. 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.

[0027] like Figure 1-4 As shown, the prefabricated intelligent monitoring photovoltaic acoustic barrier of this embodiment includes a prefabricated structural frame 1, a functional panel 2, and a monitoring component 3. The prefabricated structural frame 1 is composed of three frame units 1-1 hinged together by hinges 5. It is folded when shipped from the factory as shown in Figure 5, and unfolds into a door-shaped structure after being transported to the site as shown in Figure 6. The frame unit 1-1 and the frame support 1-3 are integrally formed metal lattice structures, which are high in strength and lightweight. The connecting plate 1-2 is hinged to the top of the frame unit 1-1, and its monitoring device mounting slot 3-1 is integrally formed and welded, serving as both a lifting handle and a monitoring component installation function. During construction, the prefabricated structural frame 1 is fastened to the existing acoustic barrier support through the positioning bolt holes 4, without the need to dismantle the original structure. Functional panel 2 uses a combination of "double-glass photovoltaic panel 2-2 + sound-absorbing panel 2-3". Sound-absorbing panel 2-3 is installed on the side facing residential areas, while double-glass photovoltaic panel 2-2 is installed on the side facing non-residential areas. During installation, first align the first latching part on the back of functional panel 2 with the second latching part of the frame, then tighten with bolts to ensure no relative displacement. The solar controller of double-glass photovoltaic panel 2-2 converts photovoltaic power, with a portion directly powering monitoring component 3, and the excess stored in the lithium battery module to ensure power supply at night or on cloudy / rainy days. Monitoring component 3 consists of environmental quality monitoring component 3-2 and noise monitoring device 3-4. After sliding both into the mounting slot 3-1, the power and signal lines are automatically connected, allowing real-time collection of noise and air quality data and transmission to a remote monitoring platform. If an additional warning function is required, it can be replaced with a roadside indicator light 3-3.

[0028] The working principle of this utility model is as follows:

[0029] First, its foldable prefabricated structural frame forms the foundation for the entire system's operation. Before being transported to the site, the entire system... Figure 5 As shown, the frame is in a folded state, saving a great deal of space. Upon arrival at the site, the construction workers unfolded it, as follows... Figure 6 As shown, a stable portal structure is formed by the connecting plate 1-2 at the top and the frame units 1-1 on both sides. The connecting plate 1-2 is fixed to the newly built barrier support or the existing barrier using bolts through its bolt holes, providing a stable installation platform for all subsequent functional modules. The monitoring device mounting slot 3-1 at the top is designed not only as a handle but also pre-integrates power and communication lines, preparing for subsequent plug-and-play functionality.

[0030] Subsequently, the modular functional panel 2 was installed. Based on actual site requirements, such as noise levels and whether road machinery or equipment needed power, the staff quickly aligned and initially secured the pre-selected single-glass photovoltaic panels 2-1, double-glass photovoltaic panels 2-2, or sound-absorbing panels 2-3 with the slots on the back of the panels using the snap-fit ​​mechanism. Finally, bolts were used for final tightening. Once installed, the functional panel 2 with the photovoltaic panels could begin operation. Its semiconductor materials, under sunlight, generated a photovoltaic effect, directly converting solar energy into direct current (DC) electricity. The single-glass photovoltaic panels 2-1 and 2-2 integrated a solar controller with a DC-DC charging circuit and a lithium battery module. The DC-DC charging circuit efficiently reduced the unstable high-voltage DC power from the photovoltaic panels to a voltage suitable for charging the lithium battery pack, thus storing the excess power for use during non-photovoltaic power generation. This electrical energy was then transmitted to the units within the system that required power through wires integrated within the frame unit 1-1. A portion of the electrical energy directly powers the installed monitoring component 3, while the other portion can be stored in the lithium battery pack or used to drive other loads after voltage regulation, thus achieving energy self-sufficiency for the entire system. Meanwhile, the sound-absorbing panels 2-3, through their porous internal material, force air molecules within the pores to vibrate and rub against the material when sound waves enter, converting sound energy into heat energy, which is then dissipated. This effectively weakens the noise intensity passing through the barrier, fulfilling its most basic noise reduction mission.

[0031] Finally, monitoring component 3, as the core of the system, is activated. The selected environmental quality monitoring sensor 3-2, noise monitoring sensor 3-4, or road indicator light 3-3 are pushed from the side along the slide rail into the top monitoring device mounting slot 3-1. When the component reaches its designated position, its electrical interface on the back automatically connects to the pre-installed power and signal interfaces in the slot, instantly completing power-on and network connection. At this time, the sensor begins to continuously collect environmental data, such as noise levels (decibels) and air quality index, which is transmitted in real time to the remote monitoring center via built-in signal transmission lines. The energy supply for the entire process comes from the electricity generated by the functional panel 2 with photovoltaic panels below it.

[0032] The construction process is as follows:

[0033] 1. A site survey is required. A detailed survey of the existing sound barriers or new support pillars is necessary to accurately measure the installation location, length, and height. Subsequently, based on the road alignment, surrounding environmental attributes (e.g., proximity to residential areas or wilderness), and functional requirements, a specific plan for each span of the barrier should be developed to determine the optimal combination of functional panels 2. On the residential side, it is recommended to use a combination of sound-absorbing panels and double-glass photovoltaic panels to balance noise reduction and power generation.

[0034] 2. All components, including the foldable prefabricated structural frame 1, various functional panels 2, and monitoring components 3, are prefabricated and pre-assembled for testing in the factory according to standardized procedures. Among them, the core prefabricated structural frame 1 will be folded and locked in the factory for minimal volume packaging and transportation, thereby significantly reducing logistics costs.

[0035] 3. For new projects, pour concrete foundations according to the design and accurately embed installation connectors; for renovation projects, clean and level the top mounting surface of existing barrier supports and check their structural bearing capacity to ensure a stable foundation for subsequent installation.

[0036] 4. Upon arrival at the site, unfold the folded prefabricated structural frame 1 on the flat ground to form a complete portal frame structure. Then, using hoisting equipment and the hoisting points designed in the top monitoring device mounting slot 3-1, smoothly lift the entire frame to the installation position at the top of the support column.

[0037] 5. Align the bolt holes of the connecting plate 1-2 precisely with the bolt holes on the top of the support or the base, and then use high-strength bolts for initial fixing. Do not tighten them completely at this time to leave room for subsequent adjustments.

[0038] 6. According to the established plan, move the selected Function 2 panel to the corresponding frame position. After roughly aligning the first engaging part on the back of Function 2 with the second engaging part of the prefabricated frame 1, the installer gently pushes it in to make them interlock, achieving rapid pre-positioning and temporary load-bearing.

[0039] 7. After the functional plate 2 is initially fixed by the locking part, bolts are used to finally tighten the functional plate 2 and the frame unit 1-1 through the predetermined bolt holes, ensuring the accuracy of the installation and the long-term reliability of the connection.

[0040] 8. Connect the cables between adjacent photovoltaic panels 2 and between the photovoltaic panels and the solar controller, and connect the main output cable to the cable tray pre-installed in the frame, leading it to the cable interface under the monitoring device mounting slot 3-1. Then, align the selected monitoring component 3 with the slide rail of the monitoring device mounting slot 3-1 from the side and push it in smoothly until its electrical interface automatically connects with the power and signal interfaces pre-installed in the slot.

[0041] 9. Finally, power on and debug the entire system. Check whether the power generation parameters of the functional board 2 with photovoltaic panels are normal, verify whether the data of each monitoring component 3 can be stably uploaded to the remote monitoring center, and test the functional integrity of other auxiliary equipment such as road indicator lights 3-3 and noise monitoring devices 3-4 to ensure that the entire system operates stably in a self-powered state.

[0042] In summary, through the installation of this device, this utility model successfully upgrades the traditional passive sound barrier into a new generation of green and intelligent infrastructure that integrates rapid deployment, functional customization, energy self-sufficiency, and intelligent sensing. The core innovation of this utility model lies in its systematic solution to the long-standing pain points of existing sound barriers—namely, the difficulty of modification, limited functionality, insufficient intelligence, and difficulty in obtaining power in the field—through three key technologies: a foldable prefabricated structural frame, modular and interchangeable functional panels, and integrated plug-and-play intelligent monitoring devices.
