Acoustic observation autonomous underwater vehicle

Abstract

The invention discloses an acoustic observation autonomous underwater vehicle, and belongs to the technical field of marine intelligent equipment, the acoustic observation autonomous underwater vehicle comprises a bow assembly, a midship assembly and a stern assembly, the bow assembly comprises an oil seal cabin and a bow cabin, a connecting frame is fixed in the oil seal cabin, the connecting frame is provided with a hydrophone through a spring, and the oil seal cabin is filled with hydraulic oil; an altimeter, a hydrophone control panel, a transducer and a first compensator are mounted in the bow cabin, and the first compensator is communicated with the oil seal cabin through an oil pipe; the midship assembly comprises a midship flow guide cover and a pressure-resistant cabin, a guide rail is arranged in the middle pressure-resistant cabin, a power supply frame is mounted on the guide rail, a movable battery pack is assembled on the power supply frame, and a lead screw motor assembly for driving the power supply frame to movably move along the guide rail is arranged in the middle pressure-resistant cabin; the stern assembly comprises a stern fairing, a buoyancy adjusting unit, a tail vane unit and a propelling unit, and the propelling unit comprises a propeller. The noise of the underwater vehicle has small influence on acoustic observation, and the underwater vehicle has high maneuverability.

Description

technical field [0001] The invention belongs to the technical field of marine intelligent equipment, and in particular relates to an autonomous underwater vehicle for acoustic observation. Background technique [0002] It has become more and more important to develop, understand and manage the ocean, and marine scientific research has important practical significance for understanding the natural phenomena of the ocean. Autonomous underwater vehicle platform technology has been rapidly developed as an important tool equipped with marine physical information sensors. Autonomous underwater vehicles rely on their own buoyancy adjustment system and propulsion system for floating, diving and depth-fixed navigation. Compared with traditional acoustic observation The equipment has the characteristics of long voyage, good maneuverability and strong concealment, making it very suitable for long-term, large-scale, continuous section ocean acoustic measurement work. In recent years, au...
