The invention discloses a supporting device of an underwater acoustic array. The supporting device comprises a supporting fin and a transducer. The horizontal section of the head of the supporting fin is arc-shaped, and the width of the horizontal section of the tail of the supporting fin is gradually reduced from a bow to a stern till that the tail of the supporting fin forms a tip. The maximum widths of the sections of the head and the tail are consistent, and the whole horizontal section of the supporting fin is symmetrically arranged along the central axis of the horizontal section; and the transducer is fixedly connected to the lower end of the supporting fin, the upper surface of the transducer is completely matched with the lower surface of the supporting fin, and the lower surface of the transducer is in a downward-protruding streamline design. Therefore, the section width of the supporting device under the same requirement is reduced to reduce the resistance area to water flow, the water flow smoothly bypasses the supporting device, the resistance generated by the supporting device to the water flow is reduced, the resistance cannot be obviously increased under the condition that the acoustic function requirement is met, generated cavitation bubbles are fewer, and the function requirement of acoustic equipment can be better met.
本发明公开了一种水下声学基阵的支撑装置,所述支撑装置包括支撑鳍和换能器,所述支撑鳍的头部的水平截面呈圆弧型,所述支撑鳍的尾部的水平截面宽度自船头至船尾方向逐渐缩小至其尾部形成尖端,且所述头部和尾部的截面最大宽度一致,所述支撑鳍的整体水平截面沿水平截面的中轴线对称设置;所述换能器固定连接设置在支撑鳍的下端,其上表面与支撑鳍的下表面完全吻合,所述换能器的下表面呈向下凸起的流线型设计。从而减小了相同需求下支撑装置的截面宽度来减小对水流的阻力面积,使水流顺滑的绕过支撑装置,减小支撑装置对水流产生的阻力,在满足声学功能需求情况下阻力不会明显增大,且产生的空泡更少,更能满足声学设备的功能需求。
