[0002] Photovoltaic sound barriers are a new type of facility that combines photovoltaic power generation with noise protection. Vibration and noise pollution not only harm human health but also reduce the land value along roads to some extent. The simplest and most effective solution is to install sound barriers along highways and rail transit lines to improve the acoustic environment quality of the surrounding area.

The adjacent sides of the metal sound insulation panel and the photovoltaic sound-absorbing and sound-insulating panel, the top of the metal sound insulation panel, and the bottom of the photovoltaic sound-absorbing and sound-insulating panel are all fixedly connected to the columns via metal connectors. This utility model's photovoltaic sound barrier, by organically combining a composite hollow structure with a photovoltaic sound insulation panel to form an integrated sound barrier, not only has excellent sound absorption and insulation effects for low-frequency noise, but also has power generation functions on both the front and back, thereby improving the power generation efficiency of the photovoltaic sound barrier. It not only increases the light-receiving surface area of ​​the photovoltaic modules, but also simplifies the sound barrier structure and installation process, reduces engineering investment costs, and facilitates industrialization.

[0004] However, during the use of this utility model, because the device adopts an integrated structure, it is unclear how to install it on the actual frame. The integrated structure makes the construction difficult for workers, and at the same time, it is easy to disassemble and maintain it, which affects work efficiency and cannot meet production needs. Therefore, a vertical photovoltaic soundproof screen is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vertical photovoltaic sound barrier, which has the advantage of being easy to construct and install. It solves the problem that existing photovoltaic sound barriers use an integrated structure, but it is unclear how to install them on the actual frame. The integrated structure makes construction difficult for workers and also makes disassembly and maintenance convenient, affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical photovoltaic sound barrier, comprising a crash barrier and an installation frame fixedly connected to the top of the crash barrier, wherein the installation frame is provided with a modular installation structure for convenient construction and installation.

[0007] The modular installation structure includes a modular frame slidably connected inside the installation frame. Positioning strips extending into the installation frame are fixedly connected to both the left and right sides of the modular frame. An installation cover plate extending into the top of the installation frame is slidably connected. Positioning blocks extending into the installation frame are fixedly connected to both the left and right sides of the installation cover plate. An installation bolt extending into the positioning block is threadedly connected to one side of the installation frame.

[0008] Furthermore, the inner wall of the mounting frame is provided with a positioning groove that matches the positioning strip, and the positioning block is connected to the positioning groove by a sliding connection.

[0009] Furthermore, sealing gaskets are fixedly connected to the top and bottom of the modular frame, and the two sealing gaskets are respectively attached to the modular frame and the mounting cover plate.

[0010] Furthermore, a sound insulation component and a photovoltaic component are fixedly connected inside the modular frame, and the thickness of the sound insulation component and the photovoltaic component is equal to the inner width of the modular frame.

[0011] Furthermore, the sound insulation component includes a metal sound insulation board, a composite sound insulation board, glass wool, foam plastic and sound-absorbing fabric, with two of each of the metal sound insulation board and glass wool.

[0012] Furthermore, the composite sound insulation board, glass wool, and foam plastic are all located between two metal sound insulation boards, the foam plastic is located between two glass wools, and the sound-absorbing fabric is located on the back metal sound insulation board.

[0013] Furthermore, the photovoltaic module includes a photovoltaic panel body, a transparent sound insulation panel, a protective panel, and an adhesive coating, and the sound insulation component and the photovoltaic module are fixedly connected by the adhesive coating.

[0014] Furthermore, the transparent sound insulation panel is located on the front of the photovoltaic module, and the front of the transparent sound insulation panel is on the same plane as the front of the modular frame.

[0015] Compared with the prior art, this utility model provides a vertical photovoltaic soundproof barrier, which has the following beneficial effects:

[0016] 1. This vertical photovoltaic soundproof barrier, with its modular frame and positioning strips, facilitates the installation of the modular frame inside the mounting frame. The installation cover and positioning blocks protect the top of the modular frame and improve the overall integrity of the mounting frame. The modular design facilitates construction and installation, as well as transportation. When maintenance is required, it can be independently disassembled, reducing construction costs and simplifying maintenance.

[0017] 2. This vertical photovoltaic soundproof barrier, through the installation of protective plates and adhesive coatings, facilitates the fixing of soundproof components and photovoltaic modules, thereby enabling its overall installation within a modular frame. Simultaneously, the use of transparent soundproof panels reduces the impact on the light transmittance of the photovoltaic panels while providing sound insulation, thus improving photoelectric conversion efficiency. This addresses the problem of existing photovoltaic soundproof barriers using an integrated structure, which lacks clarity on how to install them onto the actual frame. The integrated structure makes construction difficult for workers and hinders disassembly and maintenance, impacting work efficiency. Attached Figure Description

[0024] 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, and not all embodiments. 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.

[0025] Please see Figures 1 to 3In this embodiment, a vertical photovoltaic sound barrier includes a crash barrier 1 and an installation frame 2 fixedly connected to the top of the crash barrier 1. The installation frame 2 has a modular installation structure for easy construction and installation. The modular installation structure includes a modular frame 3 slidably connected to the inside of the installation frame 2. Positioning strips 4 extending into the inside of the installation frame 2 are fixedly connected to both the left and right sides of the modular frame 3. An installation cover plate 6 extending into the top of the installation frame 2 is slidably connected to the top of the installation frame 2. Positioning blocks 7 extending into the inside of the installation frame 2 are fixedly connected to both the left and right sides of the installation cover plate 6. An installation bolt 9 extending into the inside of the positioning block 7 is threadedly connected to one side of the installation frame 2.

[0026] Specifically, the inner wall of the mounting frame 2 is provided with a positioning groove 8 that is compatible with the positioning strip 4. The positioning block 7 is connected to the positioning groove 8 by a sliding connection. The top and bottom of the modular frame 3 are fixedly connected with sealing gaskets 5. The two sealing gaskets 5 are respectively attached to the modular frame 3 and the mounting cover plate 6.

[0027] It should be noted that the sealing gasket 5 is used to fill the gaps and holes in the sound insulation structure to prevent sound from leaking through the gaps. It can effectively improve the overall sealing of the sound insulation structure and enhance the sound insulation effect. The mounting frame 2 and the modular frame 3 are both made of aluminum.

[0028] Please see Figure 2 and Figure 4 In this embodiment, a sound insulation component 10 and a photovoltaic component 11 are fixedly connected inside the modular frame 3. The sum of the thicknesses of the sound insulation component 10 and the photovoltaic component 11 is equal to the inner width of the modular frame 3. The sound insulation component 10 includes a metal sound insulation board 101, a composite sound insulation board 102, glass wool 103, foam plastic 104, and sound-absorbing fabric 105. There are two of each of the metal sound insulation board 101 and glass wool 103.

[0029] Specifically, the composite sound insulation board 102, glass wool 103 and foam plastic 104 are all located between the two metal sound insulation boards 101, the foam plastic 104 is located between the two glass wools 103, and the sound-absorbing fabric 105 is located on the metal sound insulation board 101 on the back.

[0030] It should be noted that glass wool 103 has advantages such as light weight, high sound absorption coefficient, and good fire resistance; its fibers are long and interwoven to form a large number of tiny pores. When sound waves enter the pores, they cause air vibration and convert sound energy into heat energy through friction, thereby achieving a sound absorption effect. Foam plastic 104 has the characteristics of being lightweight and having good sound absorption performance. It has a large number of closed or open pore structures inside, which can effectively absorb sound waves. Sound-absorbing fabric 105 is usually a fabric made of fibrous materials. It has good decorative properties and a certain sound absorption capacity and can absorb some mid-to-high frequency sound waves.

[0031] It should be noted that the metal sound insulation board 101 has high strength and rigidity, and can effectively block the propagation of sound waves; the composite sound insulation board 102 is generally composed of multiple layers of different materials, with the middle layer being sound insulation material and the two sides being metal plates. This structure combines the advantages of different materials and has good sound insulation performance and impact resistance.

[0032] Please see Figure 2 and Figure 5 In this embodiment, the photovoltaic module 11 includes a photovoltaic panel body 111, a transparent sound insulation panel 112, a protective panel 113, and an adhesive coating 114. The sound insulation component 10 and the photovoltaic module 11 are fixedly connected by the adhesive coating 114. The transparent sound insulation panel 112 is located on the front of the photovoltaic module 11, and the front of the transparent sound insulation panel 112 is on the same plane as the front of the modular frame 3.

[0033] Specifically, the transparent sound insulation board 112 is a polycarbonate board with good light transmittance, which can meet the needs of some places that require lighting, while also having a certain sound insulation performance.

[0034] The working principle of the above embodiments is as follows:

[0035] First, the staff transports the modular frame 3 to the designated location. Then, they remove the mounting bolts 9 and take off the mounting cover plate 6. Next, they align the positioning strip 4 on the modular frame 3 with the positioning groove 8 on the mounting frame 2. At this point, the modular frame 3 slides into the mounting frame 2 from the top. After installation, the mounting cover plate 6 is put on and fixed with the mounting bolts 9.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
