Description

Technical Field

[0001] The utility model relates to the field of rail transit sound insulation barriers, in particular to an adjustable sound absorbing and insulating sound barrier device for rail high-speed transportation. Background Art

[0002] Rail transit passing through cities often faces the situation of passing by residential areas, commercial areas, schools, and hospitals. The amount of noise around these places needs to be strictly controlled. When trains in rail transit pass, very loud noise will be generated. If not handled, it will cause noise pollution and affect the normal life of citizens. Therefore, sound barriers made of sound-absorbing and sound-insulating materials are set on both sides of urban rail transit to minimize the amount of noise spread outward when trains pass.

[0003] The sound-absorbing and sound-insulating barrier of rail high-speed transportation is mainly composed of two parts: steel structure columns and sound-absorbing and sound-insulating screen panels. The columns are the main load-bearing components, which are fixed to the ground on both sides of the track by bolts or welding. The sound-absorbing and sound-absorbing panels are the main sound-absorbing and sound-absorbing components installed between the steel structure columns to form a continuous sound-absorbing and sound-insulating barrier wall. In order to reduce the dust that is blown away by the high-speed air flow when the train passes, a layer of light-transmitting baffle structure is generally designed on the sound-absorbing and sound-insulating barrier. During long-term use, a large amount of dust will adhere to the surface of the baffle, affecting its light transmittance, and it needs to be cleaned regularly. However, the baffle on the current sound-absorbing and sound-insulating barrier is a fixedly installed structure. When cleaning, workers need to climb to the top of the barrier to work, which is dangerous and not conducive to improving the cleaning efficiency of the dust-proof baffle of the sound-absorbing and sound-insulating barrier.

[0004] Therefore, in order to address the problem that the dust baffles on the sound-absorbing and sound-insulating barriers used in the above-mentioned urban rail transit are inconvenient to clean, a sound-absorbing and sound-insulating barrier with adjustment capability is designed to facilitate the control of the lifting and lowering of the dust baffles, allowing workers to clean the dust baffles at a low place, thereby reducing the danger of cleaning work and greatly improving cleaning efficiency.
