A disc-shaped underwater glider with multi-dimensional motion

Abstract

The invention discloses a multi-dimensional moving disc type underwater glider and relates to the field of underwater gliders. The underwater glider is in a disc structure form. A main body structurecan move in all directions and has same hydrodynamic performance as a result of the symmetrical structures. A buoyancy adjusting device can adjust the size of net buoyance to generate a driving force,through which the underwater glider sinks and floats and the underwater glider suspends underwater. A linked adjusting device adjusts distribution of center of gravity of the underwater glider by linking a follow-up stable wing and a sliding mass block, so that the underwater glider glides stably along a direction and turns quickly. The underwater glider has a multi-dimensional moving ability inan underwater space and can meet the actual demand on investigation of a three-dimensional marine environment and the demand on long-term monitoring and data acquisition in a key area.

Description

technical field [0001] The invention relates to the field of underwater glider, in particular to a disc-shaped underwater glider with multi-dimensional motion. Background technique [0002] Underwater glider has the characteristics of low power consumption and low cost of use. It can continuously monitor and sample data on the marine environment in a large-scale space for a long time, and has become an important application tool for current marine environmental investigations. However, the current underwater glider is mostly in the form of a slender cylindrical fixed-wing structure, and its application has the following typical problems: [0003] (1) It can only carry out two-dimensional continuous movement along a zigzag curve in a certain vertical plane, the turning and obstacle avoidance ability is relatively weak, and the movement mode is relatively simple. When adjusting the direction of movement or steering for obstacle avoidance, it involves the adjustment of the cen...

AI Technical Summary

Problems solved by technology

Limited by the structural form, the existing underwater glider has excellent hydrodynamic performance only in the direction of the body. Due to the low speed, the turning radius of the body is hundreds or even thousands of times the length of the body, and it is impossible to adjust the direction flexibly. It is often too late to adjust the direction and collide with obstacles in front, and even most gliders do not have the ability to adjust the direction and avoid obstacles

[0004] (2) Limited by the structural form of the body, the underwater glider with the slender cylindrical structure is difficult to turn, has a relatively long turning radius, and is easily affected by ocean currents. Its attitude adjustment can only be realized in a large-scale space, so it cannot Long-term monitoring and data collection in an important area
