Miniature multi-purpose underwater unmanned submersible vehicle shell platform with superhydrophobic surface

Abstract

The invention discloses a shell platform of a miniature multi-purpose underwater unmanned submersible with a super-hydrophobic surface, which includes a shell, a shell bottom, and an empennage. The hemispherical head is composed of a cylindrical section located behind the hemispherical head. The front end of the hemispherical head is a circular plane; the bottom of the shell is fixedly connected to the rear part of the shell and is in the shape of a truncated cone. Connection, and on the small circle of the round table, there is a ring with a certain length and thickness at the rear of the shell bottom; the empennage is fixedly connected to the shell bottom, and its thickness decreases from the connecting plane to the outer edge, perpendicular to the shell The cross-sectional shape of the central axis of the body platform is an isosceles triangle, and the side is a flat plane. The unmanned submersible has good drag reduction characteristics, which greatly reduces the resistance it suffers when moving in water, thereby having a longer voyage; and the invention is simple to manufacture, low in cost, and suitable for wide-scale use.

Description

technical field [0001] The invention belongs to the technical field of underwater unmanned underwater vehicles, in particular to a super-hydrophobic surface miniature multi-purpose underwater unmanned underwater vehicle shell platform. Background technique [0002] With the rapid development of technology in recent decades, the scope of human activities has expanded from land to space and ocean. The gradual and in-depth exploration of the ocean by human beings determines the higher demand for equipment. All kinds of equipment carried by early humans when they set foot in the ocean now seem to be more like simple substitute products, which are difficult to be qualified for large-scale and in-depth exploration in the future. At present, there are more and more underwater projects such as salvaging sunken ships and detecting minerals, which requires underwater equipment to become a large-scale and standardized product. Underwater detection and operation are different from div...

AI Technical Summary

Problems solved by technology

The template method needs to cast a template with a microscopic surface structure in advance, the process is complicated, and different surface structures require different templates, and the cost is high; the electrochemical method requires a harsh processing environment and involves many chemicals, resulting in low production efficiency and high cost. Causes environmental pollution; photolithography requires sophisticated processing equipment, which is costly and inefficient

In the field of underwater operations, standardized underwater device carriers are still blank. Although some equipment for lighting and reconnaissance has appeared, most of them are substitute products that are better than nothing, and cannot be used for large-scale equipment and more exploration needs, let alone become a standardized product
