Hybrid drive type underwater glider with various working modes

Abstract

The invention belongs to the field of marine observation associated equipment and discloses a hybrid drive type underwater glider with various working modes. The hybrid drive type underwater glider comprises a shell, horizontal wings, a combination planar antenna, a vertical tail vane, an observation instrument, a fixed battery pack, a mass center adjusting device, a buoyancy adjusting device, anemergency load rejection device and a pump jetting propelling device, wherein the horizontal wings, the combination planar antenna and the vertical tail vane are installed on the outer portion of theshell, the observation instrument, the fixed battery pack, the mass center adjusting device, the buoyancy adjusting device, the emergency load rejection device and the pump jetting propelling device are installed in the shell, and meanwhile, according to the modularized design concept, the shell is designed to be provided with a stem loading cabin, an energy cabin, an attitude adjusting cabin, a buoyancy adjusting cabin and a stern maneuvering cabin. The hybrid drive type underwater glider has the beneficial effects of being low in power consumption, long in cruising range, long in endurance and the like, the flow resisting capacity is remarkably improved, various motion modes are provided, high-accuracy emergency load rejection can be executed, and therefore a target sea area can be observed in a large range and with high accuracy.

Description

technical field [0001] The invention belongs to the field of equipment related to ocean observation, and more specifically relates to a hybrid-driven underwater glider with multiple working modes. Background technique [0002] In order to meet the various observation requirements for different ocean phenomena, the underwater observation platform is required to have flexible observation methods and good comprehensive motion observation performance. There are currently two commonly used underwater observation platforms. One is a traditional underwater vehicle, which is mostly propelled by propellers. The speed is generally 3-5kn, and the maneuverability is good. It can realize directional, depth-fixed, horizontal and preset trajectory navigation. However, due to the constraints of its own power consumption and energy, the voyage is relatively short, generally ranging from a few kilometers to several hundred kilometers, and the voyage time is limited. [0003] As another emerg...

Problems solved by technology

[0004] However, further studies have shown that the above-mentioned existing equipment still has the following defects or deficiencies: First, these equipment often have problems such as underwater positioning and control difficulties, especially in the face of complex ocean flow conditions and cannot perform well against currents. capacity, which correspondingly affects the accuracy of performing various dive operations; secondly, the existing equipment has a single working mode, poor adaptability to the migration of marine phenomena, and is mostly aimed at a single observation object, and the comprehensive ability to collect marine data is weak ; Finally, most of the emergency dumping devices of this type of underwater glider adopt the structure of a direct drive motor, which is not only complex in structure, large in size and cannot be reused, but more importantly, the matching problem of internal and external water pressure is not fully considered. Sealing, and there are problems such as complicated maintenance in the later stage, too many transmission links, and insufficient reliability
