一种便携三分体式声学成像声呐结构设计

Structural Design of a Portable Three-Part Acoustic Imaging Sonar

通过对潜水员水下作业环境存在的效率和安全性较低问题进行分析,对比传统成像声呐使用脐带缆供电传输的方式,设计了一种便携三分体式声学成像声呐。该成像声呐设备采用模块化设计,各模块彼此独立,通过水密线缆进行电性连接,结构紧凑。主机舱采用手持式设计,基于霍尔效应原理在尾部设计功能切换按钮,操控便捷。电池舱安装在潜水服上,便于携带。近眼显示目镜采用头戴式设计,能够实时近眼显示探测信息,大大提高了潜水员水下作业的效率和安全性。

By analyzing the phenomenon that the efficiency and safety of divers’underwater working environment are low,and comparing with the traditional imaging sonar using umbilical cord for power transmission,a portable three-part acoustic imaging sonar is designed.The imaging sonar equipment adopts modular design,and each module is independent of each other,and is electrically connected through watertight cables,so the structure is compact.The main cabin adopts hand-held design,and the function switch button is designed at the tail based on the principle of Hall effect,which is convenient to control.The battery compartment is installed on the diving suit,which is easy to carry.The near-eye display eyepiece adopts head-mounted design,which can display the detection information near the eye in real time,greatly improving the efficiency and safety of divers’underwater operation.
