Description

Technical Field

[0001] The utility model relates to the technical field of shielding devices, in particular to a noise reduction type fully enclosed sound shielding device. Background Art

[0002] Expressways have the advantages of high speed, large traffic volume and high efficiency, but at the same time, they are also accompanied by disadvantages such as high noise. Therefore, these factors need to be taken into consideration when building expressways. For example, to solve the problem of high noise, sound insulation devices can be installed beside the highway.

[0003] The patent document with announcement number CN218508268U discloses a highway sound insulation device, including a sound insulation component, which includes two columns, each of which has a T-shaped slot on one side opposite to the other, a sound insulation board is arranged between the two columns, a buffer board is arranged on the front end side of the sound insulation board, and fixed blocks are fixedly connected on both sides of the rear end of the sound insulation board. The arc-shaped portion of the utility model has good structural stress, which can improve the anti-collision performance. In addition, the buffer board and the first damper, the first buffer spring and the second damper, the second buffer spring are combined to relieve the impact force generated by the collision.

[0004] In actual use, the highway sound insulation devices proposed in the aforementioned patent documents lack protective structures on the surface of the sound insulation panels.
