Description

Technical Field

[0001] The present invention relates to the field of highway noise reduction, and in particular to a self-generating highway noise barrier. Background Art

[0002] Urban main roads are wide, have heavy traffic volume and high noise levels. Existing road construction or environmental impact assessments of roads that have been opened to traffic all require the establishment of noise control measures and the installation of sound barriers on both sides of the road to reduce the interference of noise on surrounding people.

[0003] Currently, most noise barriers adopt a structure similar to that of a highway noise barrier disclosed in CN214737511U, which incorporates sound-absorbing and sound-isolating panels within a soundproofing shell. Sound-absorbing holes are also provided within the shell. While these barriers offer some soundproofing, further enhancements are needed. Furthermore, as outdoor roadside equipment, noise barriers can also be used for other purposes beyond soundproofing, thus achieving multifunctionality. Summary of the Invention

[0004] Therefore, the present invention provides a self-generating highway noise barrier to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A self-generating highway sound barrier comprises a lower sound insulation component, a photovoltaic panel and an upper sound insulation component arranged in sequence from bottom to top, wherein the lower sound insulation component and the photovoltaic panel are arranged vertically, and the upper sound insulation component is inclined inwardly so that its inner surface is arranged inclined downwardly; the lower sound insulation component and the upper sound insulation component each comprise an inner cover plate, an outer cover plate and a sound insulation board arranged between the inner and outer cover plates, the surface of the inner cover plate being a corrugated surface, the corrugated surface being formed by alternating a first surface inclined upwardly and a second surface inclined downwardly, and a plurality of through-holes for sound absorption are distributed side by side on the second surface.

[0007] Furthermore, the angle between the upper sound insulation component and the vertical line is 10°-30°.

[0025] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, one of ordinary skill in the art will understand other possible embodiments and the advantages of the present invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 4 As shown, this embodiment provides a self-generating highway noise barrier, comprising a lower sound insulation assembly 11, a photovoltaic panel 20, and an upper sound insulation assembly 12, arranged in order from bottom to top. The lower sound insulation assembly 11 and the photovoltaic panel 20 are arranged vertically, while the upper sound insulation assembly 12 is tilted inward (i.e., toward one side of the highway) so that its inner surface is tilted downward. This tilted arrangement of the upper sound insulation assembly 12 can better reflect noise. Preferably, the inward tilt angle of the upper sound insulation assembly 12 (i.e., the angle between the upper sound insulation assembly 12 and the vertical line) is 10°-30°.

[0028] The photovoltaic panel 20 itself has a certain soundproofing function, namely it can reflect noise back and fully utilize outdoor sunlight energy to generate electricity, realizing the multifunctional use of the sound barrier. At the same time, the photovoltaic panel 20 is located between the lower sound insulation component 11 and the upper sound insulation component 12, and both the upper and lower sides of the photovoltaic panel 20 can effectively achieve noise reduction and sound insulation.

[0029] The lower sound insulation assembly 11 and the upper sound insulation assembly 12 both include an inner cover plate 31, an outer cover plate 32, and a sound insulation board 33 disposed between the inner cover plate 31 and the outer cover plate 32. Specifically, the sound insulation board 33 can adopt a sound-absorbing and sound-insulating board structure in the prior art.

[0030] The inner cover plate 31 has a corrugated surface, meaning that both the lower sound insulation assembly 11 and the upper sound insulation assembly 12 have a corrugated inner surface. Specifically, the corrugated surface is composed of alternating upwardly sloping first surfaces 311 and downwardly sloping second surfaces 312. The second surface 312 has a plurality of sound-absorbing through-holes 313 arranged side by side.

[0031] This corrugated surface effectively reflects and scatters sound, reducing noise. Furthermore, multiple sound-absorbing holes 313 are arranged side by side on the second surface 312, facing downward. This allows for better noise absorption than traditional horizontal holes, enhancing the overall noise reduction effect of the sound barrier. Furthermore, the downward orientation of the sound-absorbing holes 313 prevents rainwater from entering through them, slowing corrosion of the internal structure and extending its service life.

[0032] The inner cover plate 31 and the outer cover plate 32 are both stainless steel cover plates. Stainless steel not only improves strength and service life, but also has a high-end and artistic quality, making the product a beautiful urban landscape on the highway. Of course, in other embodiments, the material of the inner cover plate 31 and / or the outer cover plate 32 is not limited to this, and other metal materials (such as aluminum alloy, etc.) or plastic materials may also be used.

[0033] The sound-absorbing through-hole 313 is a horizontally extending long strip-shaped opening, which allows noise to enter the interior more fully through the sound-absorbing through-hole 313 and be absorbed by the sound insulation board 33, thereby achieving better sound insulation.

[0034] Specifically, in this embodiment, sound-absorbing through-holes 313 are not provided on each second surface 312. Instead, among the multiple second surfaces 312 from top to bottom, sound-absorbing through-holes 313 are provided on the second surfaces 312 in odd-numbered rows, while the second surfaces 312 in even-numbered rows are complete surfaces without sound-absorbing through-holes 313. Such a setting can maintain the strength of the inner cover plate 31 while ensuring the uniform distribution of the sound-absorbing through-holes 313.

[0035] The two adjacent rows of sound-absorbing through holes 313 are staggered, so that the sound-absorbing through holes 313 on the entire inner side are more evenly arranged, the noise absorption effect is better, and the noise reduction effect is further enhanced.

[0036] The top of the upper sound insulation component 12 is also equipped with a light source, and the photovoltaic panel 20 supplies power to the light source; that is, the photovoltaic panel 20 generates electricity and then supplies power to the light source. The light emitted by the light source can illuminate the road well without the need for additional power supply such as mains electricity.

[0037] More specifically, the light source is a light-emitting assembly with an LED light strip. A long, rectangular lamp housing 40 is mounted on the top of the upper soundproofing assembly 12. The lamp housing 40 has an inward-facing light outlet, and the LED light strip is mounted within the lamp housing 40. The light outlet of the lamp housing 40 is provided with a light-transmitting plate. The LED light strip structure provides long, strip-shaped illumination, low power consumption, high brightness, and long-lasting illumination. Furthermore, the inward-facing light outlet allows light to be focused inward onto the road, eliminating ineffective light scattered in other directions.

[0038] The photovoltaic panel 20 is a cadmium telluride (CdTe) solar panel, consisting of a stack of CdTe glass 22 and tempered explosion-proof glass 21. This panel not only boasts high power generation efficiency but also high light transmittance, approaching that of glass, a level unattainable by traditional crystalline silicon solar panels. Besides sound insulation and self-generated electricity, it also provides daylighting and expands the field of view.

[0039] The lower sound insulation assembly 11, photovoltaic panel 20, and upper sound insulation assembly 12 are all fixedly assembled between two opposing columns 50, with sealing strips 51 provided in the assembly gaps. These sealing strips 51 seal the assembly gaps between the lower sound insulation assembly 11 and the column 50, the assembly gaps between the photovoltaic panel 20 and the column 50, and the assembly gaps between the upper sound insulation assembly 12 and the column 50. This arrangement facilitates modular installation and provides excellent sealing, effectively protecting the internal structure. More specifically, the columns 50 are made of stainless steel, which offers excellent hardness and support strength. This single material selection facilitates material handling and creates a more uniform and aesthetically pleasing appearance.

[0040] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
