Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to a sound barrier with a photovoltaic structure. Background Technology

[0002] Sound barriers, as important noise reduction devices for transportation infrastructure, are widely used in highways, municipal main roads, railway lines, and other scenarios. Their core requirement is to attenuate sound wave propagation through acoustic structures, while also adapting to complex outdoor environments and long-term operation and maintenance needs. However, existing sound barrier technologies with photovoltaic structures still have the following technical pain points. First, current sound barriers with photovoltaic structures generally adopt a rigid fixed integrated design for their sound insulation components. The sound-absorbing material and the supporting carrier are mostly fixed through non-removable connections. This design means that during later maintenance, the entire supporting structure must be disassembled to replace aging or damaged sound-absorbing components. This not only damages the structural integrity but also significantly increases the complexity and cycle of maintenance operations, making it difficult to adapt to the actual needs of rapid operation and maintenance in outdoor traffic scenarios. Meanwhile, existing technologies mostly rely on a single type of sound insulation material to construct acoustic barriers, which cannot take into account the diverse noise spectrum characteristics in traffic scenarios. Even if some solutions attempt layered sound insulation designs, the lack of effective sealing and fixing mechanisms between layers allows sound waves to easily diffract through the gaps between the layers. The actual acoustic attenuation effect is difficult to meet the technical requirements of sound barriers in sensitive areas, resulting in a significant disconnect between acoustic performance and scenario needs. Secondly, the stability and reliability of photovoltaic module angle adjustment are insufficient. At the same time, photovoltaic modules lack targeted storage and protection structures. In extreme weather or during equipment transportation, the modules are easily damaged by external impacts, affecting the long-term operating efficiency of the photovoltaic system. In addition, the connection points between the support carrier and the sound insulation components and photovoltaic adjustment units generally lack a systematic sealing design. External moisture can easily seep into the structure, causing the sound-absorbing materials to become damp and deteriorate, and the acoustic performance to degrade. It can also cause corrosion problems of electrical components such as stepper motors and terminals, shortening the overall service life of the equipment and reducing the economic efficiency of the entire life cycle.

[0017] Working Principle: Using this invention, firstly, the silencing plate 8 is embedded into the mounting cavity 7 of the support frame 4. Then, the support frame 4 is aligned with the mounting groove 2 of the vertical support plate 1, ensuring precise engagement between the rail groove 5 at the bottom of the support frame 4 and the rail 3 on the inner wall of the mounting groove 2. The support frame 4 is then pushed along the rail 3 into the mounting groove 2 by the handle groove 6 until it is flush with the inner wall of the mounting groove 2. At this point, the limiting strip 9 on the outer wall of the mounting groove 2 provides lateral restraint to the support frame 4, preventing it from slipping out due to vibration during equipment operation. Simultaneously, the sealing strip 10 on the inner wall of the limiting strip 9 tightly adheres to the outer wall of the support frame 4, filling the gap between them and blocking sound waves from diffracting through the gap. The silencing plate 8 then begins to initially attenuate the incoming noise. The inclined support plate 11 serves as the top extension structure of the vertical support plate 1. Within the slot 12 on one side of its outer wall, the first hook-and-loop fastener 13 on the inner wall of the slot 12 is bonded to the second hook-and-loop fastener 15 on the surface of the closed-cell aluminum foam 14, thus securing the closed-cell aluminum foam 14 within the slot 12. The closed-cell aluminum foam 14 utilizes its porous structure to provide secondary buffering and absorption of mid-frequency noise after initial attenuation by the sound-absorbing plate 8. Simultaneously, sound-absorbing cotton strips 17 embedded in the sound-absorbing groove 16 on the same side of the inclined support plate 11 specifically absorb high-frequency noise, forming a composite sound insulation system encompassing high-frequency, mid-frequency, and full-frequency bands with the sound-absorbing plate 8 and the closed-cell aluminum foam 14, achieving multi-dimensional noise attenuation. The bracket 29 is aligned with one side of the outer wall of the swing arm 26, allowing the bracket 29 to... The fixing hole 30 of bracket 29 is coaxially aligned with the threaded hole 28 of swing arm 26. Threaded pin 31 is inserted into fixing hole 30 and threaded hole 28 in sequence and tightened to achieve a rigid connection between bracket 29 and swing arm 26. Then, photovoltaic panel 32 is fixed on bracket 29 to complete the assembly of photovoltaic module. When it is necessary to adjust the angle of photovoltaic panel 32 to adapt to the angle of solar incidence, stepper motor 20 in cavity 19 on the other side of inclined support plate 11 is started. The output end of stepper motor 20 passes through through hole 21 on the inner wall of cavity 19 adjacent to storage groove 18. Since the limiting block 22 at the output end of stepper motor 20 is engaged in limiting hole 24 at one end of drive shaft 23, the torque of stepper motor 20 is transmitted to drive shaft 23 through limiting block 22 and limiting hole 24. The drive shaft 23 rotates synchronously. When the drive shaft 23 rotates, the limiting block 25 at its end is engaged in the limiting hole 27 of the swing arm 26, transmitting torque to the swing arm 26, causing the swing arm 26 to rotate around the axis of the drive shaft 23. The swing arm 26 drives the bracket 29 and photovoltaic panel 32 fixed thereto to rotate synchronously, realizing the adjustment of the tilt angle of the photovoltaic panel 32 to maximize the reception of solar radiation. When encountering extreme weather or when the equipment is being transported or idle, the stepper motor 20 is controlled to rotate in the opposite direction, driving the swing arm 26, bracket 29 and photovoltaic panel 32 to rotate until the photovoltaic panel 32 and bracket 29 are completely embedded in the storage groove 18 of the inclined support plate 11, completing the storage and protection of the photovoltaic module and avoiding damage to the photovoltaic panel 32 from the external environment.
