Circular-butterfly-shaped underwater glider

Abstract

The invention discloses a circular-butterfly-shaped underwater glider, and relates to the field of underwater gliders. The underwater glider comprises a non-airtight circular-butterfly-shaped shell with the hydrodynamic performance, a spherical pressure-resistant shell with the certain pressure resistance and a connecting bracket of the pressure-resistant shell and the circular-butterfly-shaped shell. A mass center adjusting device and a buoyancy adjusting device which are required by gliding motion of the circular-butterfly-shaped underwater glider are carried in the spherical pressure-resistant shell. On the basis of the symmetrical structure of the glider main body, the same hydrodynamic performance is achieved in all directions during underwater gliding, the gravity center of the glider is changed by changing the position of the heavy block through the mass center adjusting device, the buoyancy of the glider is adjusted through the buoyancy adjusting device, upward floating and sinking of the glider are achieved, and gliding motion of the glider is achieved through linkage of the two adjusting systems. The underwater glider can achieve omnidirectional movement underwater, is small in underwater turning radius, has high loading and expanding capacity, and can meet different underwater tasks.

Description

technical field [0001] The invention relates to the field of underwater glider, in particular to a disc-shaped underwater glider. Background technique [0002] The underwater glider can realize long-distance gliding motion by adjusting its center of gravity and buoyancy once in the water. It has the characteristics of low power consumption and low cost of use, and can carry out scientific research such as detection and collection in the ocean for a long time and in a large space. Activities are an important tool for ocean exploration. However, the current underwater glider is mostly in the form of a cylindrical fixed wing structure, which has the following problems: [0003] (1) Due to the limitation of the body's own structure, it is impossible to turn with a small radius when moving underwater. It needs a water area much larger than its own length to make a turn, and it cannot take advantage of narrow water areas. [0004] (2) The structure of the fuselage is fixed, the ...

AI Technical Summary

Problems solved by technology

[0003] (1) Limited by the body's own structure, it is impossible to turn with a small radius when moving underwater, and it needs to turn in waters much larger than its own length, so it cannot take advantage of narrow waters

[0004] (2) The structure of the fuselage is fixed, the detection equipment is single, there is no room for expansion, and it cannot be used for different types of scientific research work
