The invention discloses a low-noise and low-resistance underwater acoustic towed body of a wave glider, and belongs to the field of marine environment detection equipment. The problems that an existing underwater towed body device is large in size and large in weight, and the influence of noise interference in the signal collecting process is large are solved. The underwater acoustic towed body comprises an underwater towed body, and a front flow guide cover is arranged at the front end of the underwater towed body. An acoustic data acquisition and transmission module and an attitude sensor are arranged in the underwater towed body; wing plates are symmetrically arranged on the underwater towed body in pairs, hydrophones are arranged on the wing plates, and the hydrophones form an acousticthree-dimensional array; a hydrophone flow guide cover is additionally arranged at the periphery of the hydrophone; by adjusting the number of floaters and sinking blocks of the telescopic damping mechanism, the underwater acoustic towed body is integrally configured to be neutral buoyancy. The underwater acoustic towed body is connected to the wave glider through a depth-keeping towing cable andsupplies power to the underwater towed body through the underwater depth-keeping towing cable. The invention is mainly used for acquiring marine acoustic information.

    一种波浪滑翔机的低噪声低阻力水下声学拖体,属于海洋环境检测设备领域。为了解决目前的水下拖体的设备存在体积大、重量大的问题,以及采集信号过程中受到噪声干扰影响比较大的问题。水下声学拖体包括水下拖体,水下拖体的前端设有前导流罩;声学数据采集传输模块和姿态传感器设置在水下拖体内部;翼板成对且对称设置在水下拖体上,水听器设置在翼板上,多个水听器构成声学立体阵;水听器外围加装水听器导流罩;通过调节伸缩减振机构的浮子和沉块的数量,将水下声学拖体整体配置为中性浮力;水下声学拖体通过定深拖曳缆连接在波浪滑翔机上,通过水下定深拖曳缆向水下拖体供电。主要用于获取海洋声学信息。
