Abstract

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.

Description

technical field [0001] The invention belongs to the field of marine environment detection equipment, and in particular relates to an underwater acoustic drag body towed by a wave glider when acquiring marine acoustic information. Background technique [0002] Obtaining ocean acoustic information is an important content in the field of marine environment detection. The parameters obtained include marine environmental background noise, marine biological acoustic signals, and ship acoustic signals. Various marine environmental parameters can be obtained through marine acoustic information. An important parameter of nanocapacity. [0003] The current underwater detection equipment includes underwater robots, underwater gliders, underwater tow bodies, etc. The current underwater tow body equipment has the problems of large volume, heavy weight, and large flow resistance, and most of them are suitable for towing by surface ships. Consider the self-noise of underwater towing bodie...
