Description

Technical Field

[0001] This utility model relates to the field of airflow guidance technology, and in particular to an airflow guiding, permeable, and sound-absorbing barrier structure. Background Technology

[0002] To reduce the impact of railway noise, sound barriers are typically installed in residential areas to block the noise's propagation path. Sound barrier projects offer reasonable investment and good sound insulation, making them an important measure for controlling traffic noise pollution. A sound barrier is a structure inserted between the sound source and the receiver, significantly attenuating sound wave propagation and thus reducing the noise impact within a certain area where the receiver is located. With the rapid increase in infrastructure construction such as railways and highways in my country and the gradual strengthening of people's awareness of environmental noise, the demand for sound barriers, as the most effective means of mitigating noise pollution, is also increasing.

[0003] For example, the air-permeable sound barrier structure disclosed in application number 202021855882.7 has the functions of sound absorption and air permeability, which can reduce the stress on the steel column structure and bridge foundation structure under large impacts such as high-speed train pulses and extreme winds. However, the above structure cannot effectively divert air during use, thus it cannot effectively and uniformly guide the air, reducing its air diversion efficiency and utilization efficiency. It also cannot effectively provide multiple sound insulation, reducing its sound insulation efficiency and working efficiency. Therefore, we propose an air-permeable sound barrier structure. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a flow-guiding, ventilation, and sound-absorbing barrier structure that can effectively divert airflow, thereby enabling it to effectively and uniformly guide airflow, improving its flow guidance efficiency and usage efficiency, and also providing effective multi-layer sound insulation, thus improving its sound insulation efficiency and working efficiency.

[0005] To achieve the above objectives, a flow-guiding, permeable, and sound-absorbing barrier structure is provided, comprising: a main body, a first flow-guiding chamber on the left side of the main body, and second flow-guiding chambers above and below the first flow-guiding chamber; a plurality of evenly distributed first flow-guiding holes on the left inner wall of the first flow-guiding chamber, and a plurality of evenly distributed second flow-guiding holes on the left inner wall of the second flow-guiding chamber; a plurality of evenly distributed inclined grooves connected to the right side of the second flow-guiding chamber, the right side of the plurality of inclined grooves connected to the same first cavity, and the right side of the first cavity connected to the second cavity; a sound-insulating chamber on the right side of the second cavity, and a plurality of evenly distributed connecting holes on the left inner wall of the sound-insulating chamber; a plurality of evenly distributed arc-shaped grooves connected to the top and bottom of the inner cavity of the sound-insulating chamber near the right side, and the side of the plurality of arc-shaped grooves away from the sound-insulating chamber connected to the same L-shaped groove; and a plurality of evenly distributed circular holes on the right inner wall of the L-shaped groove.

[0006] According to the aforementioned air-permeable sound barrier structure, the left inner wall of the first air-permeable chamber is connected to an arc-shaped plate, and the top and bottom of the arc-shaped plate are provided with a number of evenly distributed diversion holes.

[0007] According to the aforementioned air-permeable sound-absorbing barrier structure, the top and bottom of the inner ring of the first air-permeable chamber are connected to the adjacent inclined groove by a vertical groove near the right side.

[0008] According to the aforementioned air-permeable sound barrier structure, the second cavity is connected to sound-absorbing cotton, and the sound-absorbing cotton has a number of evenly distributed sound-absorbing holes.

[0009] According to the aforementioned air-permeable sound barrier structure, sound insulation cotton is connected to the inner right wall of the sound insulation chamber, and slots are provided at the top and bottom of the main body near the left and right sides.

[0010] The above solution has at least one of the following beneficial effects: Through the cooperation between components such as the first guide hole, the second guide hole, the inclined groove and the first cavity, this technical solution enables effective diversion, thereby enabling effective and uniform flow guidance, improving its flow guidance efficiency and utilization efficiency, and enabling effective multi-layer sound insulation, thus improving its sound insulation efficiency and working efficiency.
