Current-driven anchoring type long-endurance glider

Abstract

The invention belongs to the technical field of gliding type submersibles, and particularly relates to a current-driven anchoring type long-endurance glider. The ocean flow field widely existing is effectively used, through adjusting the attack angle between an adjusting type transverse hydrofoil and the incoming flow, different kinds of lift and resistance are generated, the glider is driven to float upwards and dive, and a glider does not need to rely on a buoyancy adjusting device. The glider can float out of the water surface at regular intervals, an antenna rod on the tail is used for communication and data transmission, and the glider is fixed in a certain area through an anchoring system and cannot go with the stream. Meanwhile, the glider has the capacity of monitoring the profilemarine environment, energy consumption is low, long-time uninterrupted operation is achieved, under the condition that a regional current exists, the glider has the high safety and tacitness, energy consumption is low, long endurance is achieved, control is reliable, and the glider is suitable for area ocean environment monitoring.

Description

technical field [0001] The invention belongs to the technical field of gliding submersibles, in particular to an anchored long-endurance glider driven by ocean currents. Background technique [0002] Gliding submersible is a typical ocean exploration platform. It has been widely used in marine scientific research, such as seabed biological resource exploration, seabed topographic survey, seismic geothermal activity monitoring and marine environment monitoring. The gliding submersible can float or dive by adjusting the buoyancy to achieve the effect of continuous gliding motion. [0003] Among the existing published patents and published articles, the gliding submersible is a tool for large-scale ocean exploration. Some gliding submersibles also have the functions of underwater gliding and sitting on the bottom. It can dive into the bottom of the sea according to needs. Due to the shape of the perspective mirror, it can reduce the resistance generated by the horizontal sea...

AI Technical Summary

Problems solved by technology

[0005] (1) The maneuverability of the gliding submersible is poor, it is difficult to eliminate the interference of the ocean current, and it has the movement characteristics of drifting with the current, which cannot meet the operation requirements

Conventional AUVs have strong maneuverability, but high energy consumption, and cannot operate continuously for a long time

[0006] (2) Although conventional submersible buoys are fixed underwater, real-time communication relies on communication buoys

However, under the influence of ocean currents, the ability of its profile movement will be greatly limited

At the same time, the adjustment method of profile movement consumes a lot of energy, and the energy system it carries is difficult to meet the requirements of ultra-long working hours
