Document Type and Number:
WIPO Patent Application WO/2022/198705
Kind Code:
A1
Abstract:
An autonomous underwater vehicle for acoustic observation, comprising a bow assembly (1), a midship assembly (2), and a stern assembly (3). The bow assembly (1) comprises an oil seal cabin and a bow cabin located behind the oil seal cabin. A connecting frame (1-5) is fixed in the oil seal cabin. A hydrophone (1-7) is mounted on the connecting frame (1-5) by means of a spring (1-6). The oil seal cabin is filled with a hydraulic oil. An altimeter (1-8), a hydrophone control board (1-9), a transducer (1-10), and a first compensator (1-11) are mounted within the bow cabin. The first compensator (1-11) is communicated with the oil seal cabin through an oil pipe. The midship assembly (2) comprises a midship flow guide cover (2-1) and a middle pressure-resistant cabin on the inner sides of the midship flow guide covers. A guide rail (2-5), a power supply frame (2-6), mobile battery packs (2-7), and a lead screw motor assembly are provided within the middle pressure-resistant cabin. The stern assembly (3) comprises a stern flow guide cover (3-1), a buoyancy adjustment unit (3-4), a tail rudder unit (3-5), and a propulsion unit (3-6). Noise of the present underwater vehicle itself has less influence on acoustic observation, and the present underwater vehicle has high maneuverability.
