Problems solved by technology
[0003] The current noise barrier is not easy to clean the surface, causing too much dust on the surface of the noise barrier to cause resonance and sound transmission medium, resulting in a reduction in the sound insulation effect of the noise barrier, and it cannot be adaptively adjusted by temperature

The invention discloses a self-adjusting temperature-based sound insulation barrier for overhead, which belongs to the field of noise reduction. It is a self-adjusting temperature-based sound insulation barrier for overhead. The bar-shaped slider is ejected from the inside of the U-shaped plate, and the noise is isolated and digested by the sound-proof cotton, thereby reducing the resonance between the dust and the sound-proof wall body and the vacuum glass, improving the sound insulation effect, and the water expansion inside the chute The rubber strip expands with water to squeeze the slider, and cleans one side of the vacuum glass through the microfiber cotton at the outer end of the cleaning rod, thereby reducing the sound transmission medium and effectively improving the sound insulation effect. The sound at the top of the curved reflector, when the airflow generated by the vehicle on the elevated, the diversion groove on one side of the curved reflector disperses the airflow, reducing the wind noise generated by the airflow and the sound insulation wall body, thereby improving the sound insulation of the sound insulation wall body Effect.
Description
technical field [0001] The invention relates to the field of noise reduction, and more specifically relates to a self-adjusting temperature-based sound insulation barrier for elevated structures. Background technique [0002] Sound insulation walls (sound barriers) are mainly used for sound insulation and noise reduction in transportation and municipal facilities such as expressways, elevated compound roads, and urban light rail subways, to control the impact of traffic noise on nearby urban areas, and can also be used for isolation of factories and other noise sources. Sound noise reduction is divided into pure sound insulation reflective sound barriers, and composite sound barriers that combine sound absorption and sound insulation. The latter is made of more effective sound insulation. Most sound barriers use absorption Sound and sound insulation hybrid products, this type of product is characterized by targeted control of the generation and transmission of road noise, su...
