Outdoor sound wave fog dispersal device and method thereof
The invention relates to an outdoor sound wave fog dispersal device and method. The outdoor sound wave fog dispersal device comprises at least two sets of sound production assemblies. Each set of sound production assembly comprises a sound production source, a rotating base and a pitching support, the pitching support is arranged on the rotating base and can rotate around a horizontal axis, the rotating base drives the pitching support to rotate around a vertical axis, and the sound production source is arranged on the pitching support and moves along with the pitching support. The sound production source can emit sound waves in the central axis direction of the sound production source. In the working process, the central axes of the sound production sources of the at least two sets of sound production assemblies point to the same area, two or more beams of sound waves with the same frequency or difference frequency intersect in the area to form a crossed sound field, an advection fog field can be converted into an eddy current fog field, the collision effect of fog drops is improved, the sound wave fog dispersal effect is improved, and then the fog dispersal efficiency is improved.
本发明涉及一种户外声波消雾装置及其方法，户外声波消雾装置包括：至少两套发声组件。每套发声组件包括发声源、旋转底座以及俯仰支架，俯仰支架设置在旋转底座上，俯仰支架能够绕水平轴线旋转，旋转底座带动俯仰支架能够绕垂直轴线旋转，发声源设置在俯仰支架上，随俯仰支架一起运动。发声源能够沿其自身的中心轴线方向发射声波。工作时，至少两套发声组件的发声源中心轴线指向同一区域，两束或多束同频或差频的声波在这一区域交会，形成交叉声场，有助于将平流雾场转化为涡流雾场，从而增加雾滴的碰并效应，提升声波消雾的效果，进而提高除雾效率。
