Abstract
Description
Technical Field
[0001] This utility model relates to the field of traffic noise reduction equipment technology, specifically a sound-absorbing barrier with a flower-shaped structure. Background Technology
[0002] Sound barriers are currently the most widely used noise reduction measure in the field of traffic noise control. They achieve noise reduction by shielding and blocking the propagation path of traffic noise through the barrier structure. Therefore, the sound absorption performance of the barrier material and the duration for which it retains this performance directly affect the overall noise reduction effect and durability of the sound barrier. However, most sound barrier panels used in China currently rely on porous materials filled within the barrier to achieve sound absorption and noise reduction. This fails to address the durability issue of overly loose porous material structures; that is, the better the sound absorption effect of a porous material structure, the less durable it is. Utility Model Content
[0003] The purpose of this invention is to provide a sound-absorbing barrier with a flower-shaped structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a flower-shaped sound-absorbing barrier, comprising a screen body and sound-absorbing components uniformly distributed on the screen body, wherein the sound-absorbing components include a first noise reduction part and a second noise reduction part; the outer peripheral surface of the first noise reduction part is provided with a plurality of sharp corners with identical structures, and the first noise reduction part is surrounded by the plurality of sharp corners; the first noise reduction part and the second noise reduction part are uniformly distributed along the length direction of the screen body, and the second noise reduction part is located below the first noise reduction part.
[0005] As a preferred technical solution of this utility model: the first noise reduction part and the second noise reduction part are further provided with a third noise reduction part, and the third noise reduction part is located between any two adjacent sharp corners.
[0006] As a preferred technical solution of this utility model: both the first noise reduction part and the sharp corner are recessed into the interior of the screen body, and the space formed by the sharp corner is connected to the first noise reduction part.
[0007] As a preferred technical solution of this utility model: the noise reduction range formed by the third noise reduction part is independent of the noise reduction range formed by the first noise reduction part.
[0008] As a preferred technical solution of this utility model: the corresponding sides of the first noise reduction part and the second noise reduction part are proportional and the corresponding angles are equal, and the length and width of the first noise reduction part are greater than the length and width of the second noise reduction part.
[0009] As a preferred technical solution of this utility model, the third noise reduction part is rhomboid in shape.
[0010] As a preferred technical solution of this utility model: the first noise reduction part and the second noise reduction part are arranged alternately on the screen body from the bottom to the top, and the third noise reduction part between the facing surfaces of the first noise reduction part and the second noise reduction part is connected together.
[0011] As a preferred technical solution of this utility model: the material of the screen body is cement-based inorganic material, and the sound-absorbing component is stamped and formed on the screen body.
[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows: by forming a sound-absorbing component on the surface of the screen, and the two noise-reducing parts on the sound-absorbing component can absorb traffic noise. Specifically, by utilizing the cooperation between the two noise-reducing parts and the sharp corner, the overall energy of traffic noise can be reduced by the multiple interference effects of alternating reflection and scattering on the surface of the screen. Therefore, the device can use its own structure to absorb and reduce noise. Attached Figure Description

[0017] Please see Figure 1-2This invention provides a flower-shaped sound-absorbing barrier, including a screen body 1 and sound-absorbing components 4 uniformly distributed on the screen body 1. The sound-absorbing components 4 include a first noise-reducing part 2 and a second noise-reducing part 5. The outer circumferential surface of the first noise-reducing part 2 is provided with several identical sharp corners 3, which surround the first noise-reducing part 2. The first noise-reducing part 2 and the second noise-reducing part 5 are uniformly distributed along the length of the screen body 1, with the second noise-reducing part 5 located below the first noise-reducing part 2. In summary, by forming the sound-absorbing components 4 on the surface of the screen body 1, and by using the two noise-reducing parts on the sound-absorbing components 4 to absorb traffic noise, specifically, by utilizing the cooperation of the two noise-reducing parts and the sharp corners 3, the overall energy of traffic noise can be reduced through multiple interference effects of alternating reflection and scattering on the screen body surface. Therefore, this device can absorb and reduce noise using its own structure.
[0018] Furthermore, since the first noise reduction part 2 and the second noise reduction part 5 are also provided with a third noise reduction part 6, and the third noise reduction part 6 is located between any two adjacent sharp corners 3, the noise reduction area of the screen body 1 can be further expanded to improve the noise reduction effect of the screen body 1. In addition, since the third noise reduction part 6 is located between two adjacent sharp corners 3, the entire sound-absorbing component 4 is more aesthetically pleasing. Specifically, when the sound-absorbing component 4 is distributed on the screen body 1, it presents a flower shape on the screen body 1, similar to the shape of a plum blossom, thus making the screen body 1 look more aesthetically pleasing in practical applications.
[0019] Furthermore, since both the first noise reduction part 2 and the sharp corner 3 are recessed into the screen body 1, and the space formed by the sharp corner 3 is connected to the first noise reduction part 2, when noise enters the first noise reduction part 2 and the noise reduction range formed by the sharp corner 3, it is reflected inside the noise reduction range, which is beneficial for noise absorption and reduction.
[0020] In addition, since the noise reduction range formed by the third noise reduction section 6 is independent of the noise reduction range formed by the first noise reduction section 2, the sound waves generated by noise can be separated by each noise reduction section. After separation, the sound waves in the third noise reduction section 6 and the first noise reduction section 2 do not interfere with each other. Furthermore, the third noise reduction section 6 is set in a rhombus shape, so it can absorb sound waves while also enhancing the aesthetics of the sound-absorbing component 4.
[0021] To fully utilize the space of the screen 1, the corresponding sides of the first noise reduction unit 2 and the second noise reduction unit 5 are proportional and their corresponding angles are equal, and the length and width of the first noise reduction unit 2 are greater than the length and width of the second noise reduction unit 5. Therefore, the second noise reduction unit 5 can be filled between any two adjacent first noise reduction units 2 to complete the utilization of the internal space of the screen 1.
[0022] Specifically, the first noise reduction unit 2 and the second noise reduction unit 5 are arranged alternately from the bottom to the top of the screen 1, and the third noise reduction unit 6 between the facing surfaces of the first noise reduction unit 2 and the second noise reduction unit 5 is connected together.
[0023] In addition, most of the sound-absorbing panels used in domestic sound barriers are made of metal, which has the following main problems: the anti-corrosion methods for metal materials are generally inadequate, especially at the connecting rivets, which are prone to rust, have poor durability, and affect the functionality and aesthetics; the insufficient porosity of the outer metal material (up to 35%) reduces the noise absorption effect, thus affecting the secondary absorption of reflected sound and resulting in reduced sound absorption performance; metal materials are high-energy-consuming materials, which do not conform to the development trend of low-carbon and emission-reduction materials.
[0024] Therefore, the material of the screen 1 described in this solution is cement-based inorganic material, which makes the sound absorption coefficient of the screen 1 outstanding, more than 20% higher than that of ordinary non-metallic sound-absorbing panels, increasing from 0.5 to 0.6; the sound insulation is significantly increased, 20% higher than that of ordinary non-metallic sound-absorbing panels, increasing from 30dB to 36dB; the cost is low, 30% lower than that of metal sound-absorbing panels; the use of non-metallic inorganic materials results in low energy consumption and low carbon emissions, reducing carbon emissions by 70% or more compared to metal sound-absorbing panels, thus effectively solving the problems existing in metal screens.
[0025] Furthermore, since the sound-absorbing component 4 is stamped onto the screen body 1, the forming of the sound-absorbing component 4 is simple and convenient, thus further reducing the production cost of the equipment.
[0026] 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.
