Abstract

The invention discloses an auto-rotating air and sound barrier used for a traffic bridge. The barrier comprises at least two supporting stand columns. The supporting stand columns are arranged at interval and are fixedly combined with a bridge floor or a base. At least two noise-reducing blades which automatically rotate to block flow and guide flow are rotatably connected between two adjacent supporting stand columns. The noise-reducing blades are characterized that rotation torques are different with different plate body mass distribution. The noise-reducing blades are connected with the supporting stand column through rotating horizontal shafts. A gap space used to remove rotation obstruction between the noise-reducing blades in a free rotation process of the noise-reducing blades and used to discharge and guide flow is reserved on a rotation track between two adjacent noise-reducing blades. The auto-rotating air and sound barrier organically combines ideas of a sound barrier and an air barrier, and is advantaged by high efficiency and reasonable, simple and practical, and novel and beautiful, and the barrier is suitable to popularize, and economic benefit is obvious.

Description

technical field [0001] The invention relates to the technical field of vehicle bridge protection facilities, in particular to an intelligent and convenient barrier for flow blocking, flow diversion and noise reduction through the intelligent and convenient rotation of self-rotating sound-absorbing blades to adapt to wind speed changes and rotate at different angles. 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 tr...
