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 no...

Embodiment Construction

[0023] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] This application discloses a disc-shaped underwater glider with multi-dimensional motion, please refer to Figure 1-5 , the multi-dimensional motion disc-shaped underwater glider includes a disc-shaped housing 1, the disc-shaped housing 1 is the hydrodynamic shape of the underwater glider of the present application, and the interior of the disc-shaped housing 1 is hollow and used to install the underwater glider. Other equipment of the glider, in this application, the disc-shaped shell 1 is formed by connecting the upper shell plate 1a and the lower shell plate 1b, and the disc-shaped shell is formed between the upper shell plate 1a and the lower shell plate 1b The inner hollow area of ​​1, the upper and lower here are only the relative positional relationship, the upper housing disc 1a and the lower housing disc 1b are both disc-shap...

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...
