Description

Technical Field

[0001] This utility model relates to the field of traffic noise control, specifically a three-dimensional sound-absorbing barrier. Background Technology

[0002] For controlling traffic noise, sound barrier technology is often widely adopted due to its economic efficiency and effectiveness. Sound barriers are typically installed between noise sources and noise-sensitive areas to block or absorb noise, reducing noise pollution in sensitive areas and meeting environmental protection requirements. Existing sound-absorbing barriers generally consist of a sound-insulating module and a sound-absorbing module fixed to one side of the sound-insulating module. The sound-absorbing module is a monolithic structure, which is bulky and inconvenient to disassemble, install, and transport. Therefore, there is a need for a sound-absorbing barrier with a simple structure that is easy to disassemble, install, and transport. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional sound-absorbing barrier, comprising a support portion and a sound-absorbing component mounted on the support portion; the sound-absorbing component comprises a first unit and a second unit, and both the first unit and the second unit comprise a plate; the side of the plate facing the sound source is provided with a sound-absorbing portion, and the side of the plate away from the sound-absorbing portion is adapted to be connected to a slot provided on the support portion through a provided pin.

[0005] As a preferred technical solution of this utility model: the number of sound-absorbing parts is multiple, and the multiple sound-absorbing parts are distributed on the sound-absorbing component in a mosaic pattern.

[0006] As a preferred technical solution of this utility model: the support part is further provided with a groove, and after the plate is installed into the groove, the outer wall surface of the plate is flush with the outer wall surface of the support part.

[0007] As a preferred technical solution of this utility model: the sound-absorbing part includes an outer ring and an inner ring, and the cross-sections of the outer ring and the inner ring are both square.

[0008] As a preferred technical solution of this utility model: the side length of the outer ring is 3 mm, and the distance between the outer end face of the sound-absorbing part and the outer end face of the plate is 2 mm.

[0009] As a preferred technical solution of this utility model, the distance between the facing surfaces of the outer ring and the inner ring is 0.5 mm.

[0010] As a preferred technical solution of this utility model: both the support part and the sound-absorbing component are made of concrete, and the end face of the support part is also provided with a through hole.

[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows: since the sound-absorbing component is composed of multiple units, it is easy to assemble the sound-absorbing component onto the support; in particular, since the sound-absorbing component and the support are separate structures, firstly, both the sound-absorbing component and the support can be produced and manufactured independently; secondly, it makes it simple and convenient to replace the sound-absorbing component and the support after damage; and thirdly, both the support and the sound-absorbing component can be transported and handled independently.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0019] Please see Figure 1-5The present invention provides an embodiment of a three-dimensional sound-absorbing barrier, comprising a support portion 1 and a sound-absorbing component 2 mounted on the support portion 1; the sound-absorbing component 2 comprises a first unit 23 and a second unit 24, and both the first unit 23 and the second unit 24 comprise a plate body 20; the side of the plate body 20 facing the sound source is provided with a sound-absorbing portion 21, and the side of the plate body 20 away from the sound-absorbing portion 21 is adapted to be connected to a slot 3 provided on the support portion 1 through a provided pin 22.

[0020] In summary, since the sound-absorbing component 2 is composed of multiple individual units, it is easy to assemble the sound-absorbing component 2 onto the support part 1. In particular, since the sound-absorbing component 2 and the support part 1 are separate structures, firstly, both the sound-absorbing component 2 and the support part 1 can be produced and manufactured independently; secondly, it makes it simple and convenient to replace the sound-absorbing component 2 and the support part 1 after damage; and thirdly, both the support part 1 and the sound-absorbing component 2 can be transported and handled independently.

[0021] Furthermore, since there are multiple sound-absorbing parts 21, and these multiple sound-absorbing parts 21 are distributed on the sound-absorbing component 2 in a mosaic pattern, it can effectively improve the absorption rate of traffic noise after repeated reflections on the surface of the sound-absorbing barrier, and reduce its overall energy; therefore, while achieving noise reduction, it can also beautify the appearance of the entire sound-absorbing barrier; specifically, the sound-absorbing component 2 is distributed in a glass mosaic pattern.

[0022] Furthermore, since the support part 1 is also provided with a groove 4, and after the plate 20 is installed into the groove 4, the outer wall surface of the plate 20 is flush with the outer wall surface of the support part 1. Therefore, the sound-absorbing component 2 can be wrapped around the support part 1 by the groove 4. At the same time, the groove 4 can accommodate the plate 20, thus preventing the sound-absorbing component 2 from protruding excessively outward.

[0023] Based on the above solution, since the sound-absorbing part 21 includes an outer ring 25 and an inner ring 26, and the cross-sections of the outer ring 25 and the inner ring 26 are both square.

[0024] Specifically, the outer ring 25 has a side length of 3 mm, and the distance between the outer end face of the sound-absorbing part 21 and the outer end face of the plate 20 is 2 mm. The distance between the facing surfaces of the outer ring 25 and the inner ring 26 is 0.5 mm. Therefore, by using multiple sound-absorbing parts 21, the absorption rate of traffic noise after alternating reflections on the surface of the sound-absorbing barrier can be effectively improved, thus reducing its overall energy.

[0025] Furthermore, both the support part 1 and the sound-absorbing component 2 are made of concrete, and the end face of the support part 1 is provided with a through hole 5, wherein the through hole 5 can be filled with sound-absorbing material, which reduces the weight of the support part 1 and improves the sound absorption and sound insulation capabilities of the sound-absorbing component 2.

[0026] Sound barriers constructed using cement-based materials can solve current problems associated with metal sound-absorbing panels, such as corrosion, poor durability of porous materials used for sound absorption, insufficient porosity in metal materials leading to reduced noise absorption, and high energy consumption. They are also significantly cheaper, costing 30% less than metal sound-absorbing panels. Using non-metallic inorganic materials results in lower energy consumption and carbon emissions, reducing carbon emissions by 70% or more compared to metal sound-absorbing panels. The sound absorption coefficient is outstanding, increasing by more than 20% compared to ordinary non-metallic sound-absorbing panels, from 0.5 to 0.6; the sound insulation is also significantly increased, increasing by 20% compared to ordinary non-metallic sound-absorbing panels, from 30dB to 36dB.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
