Abstract

The invention discloses a shutter-type wind sound barrier. The shutter-type wind sound barrier comprises at least two support columns, the support columns are distributed at intervals and fixed to the ground or a base, at least two soundproofing vanes are rotationally connected to the support columns and located between the two adjacent support columns, the soundproofing vanes are used for sound absorption, sound insulation, flow diversion and flow disturbing through rotation, the upper portions and / or the lower portions of the soundproofing vanes are inclined toward the leeward wind direction, at least one free plate edges of the soundproofing vanes extend outwards, and narrow gaps for forming flow diversion channels and flow disturbing channels are formed between the adjacent soundproofing vanes. In the resistance to strong winds, the inherent stiffness of the soundproofing vanes is utilized to block the flow, the inclined angle and the inclined direction of the soundproofing vanes are utilized to diverse the flow, and the narrow gaps are utilized to discharge, so that the windproof performance of a vehicle, a train, a bridge and the like is better; and the ideas of sound barrier and wind barrier are combined organically, and the shutter-type wind sound barrier is capable of being efficient, reasonable, simple, convenient, novel and attractive, suitable for promotion and great in economic benefits.

Description

technical field [0001] The invention relates to the technical field of high-speed railway bridge sound barriers and wind barriers, in particular to a louver-type wind noise barrier. Background technique [0002] With the continuous development of my country's transportation construction, the number of roads and railways built continues to increase, which not only crosses residential areas and commercial office areas, causing noise pollution, but also may cross strong winds or windy areas, causing safety hazards. Noise pollution has had a great impact on people's life and work, and people have great opinions on this; strong winds may cause traffic accidents such as sideslips and rollovers in moving cars and trains, affecting normal driving effects. And the prohibition of vehicle passage or train suspension under strong wind may cause great economic losses. Therefore, noise pollution and strong wind hazards have become problems that need to be solved in the transportation ind...
