An outer cabin structure for an underwater vehicle

Abstract

The application discloses an outer cabin structure for an underwater vehicle, which includes an outer shell and a hard frame; the overall outer shell is a flat horizontal hexagonal prism structure; the two V-like ends of the horizontal hexagonal prism structure respectively form a bow The outer peripheral surface of the shell is provided with a raised skirt along the horizontal direction; the hard frame is detachably arranged in the middle part of the shell. Through this shell structure design, the rolling stability can be significantly improved under the premise of increasing the lift-to-drag ratio, and the accuracy of data collection can be ensured. Moreover, it also has the advantages of stronger navigation maneuverability, more advantageous lift-to-drag ratio, and a certain recovery force when it is not expected to pitch, which can save propulsion or control energy and increase the cruising range. It can also meet the space requirements of the internal loading as much as possible, and realizes the modular design as a whole, which is convenient for overall dismounting and hoisting, and is convenient for maintenance and replacement. At the same time, the rigid frame can also play a supporting role to strengthen the mechanical strength of the overall structure and resist greater external pressure.

Description

technical field [0001] The present application relates to the technical field of underwater navigation, and in particular, to an outer cabin structure for an underwater vehicle. Background technique [0002] With the deepening of human exploration of the ocean and the development of marine economy, more and more attention has been paid to the research and development of underwater unmanned vehicles. According to the different mission objectives and ways of use, unmanned underwater vehicles can be roughly divided into two categories: cabled and cableless. Cabled underwater vehicles are mostly used for short-range detection and underwater collection and maintenance work, and the manipulation and energy supply are realized through underwater cable transmission. Cableless underwater vehicles are mostly used for medium and long-distance seabed topography and resource surveys. They realize underwater navigation through their own batteries, and collect data through their own relat...

AI Technical Summary

Problems solved by technology

The shell structure of the existing underwater vehicles is mostly a cylindrical design, similar to a torpedo shape, but the roll stability is insufficient, and it is easily disturbed by the water flow during underwater detection tasks, resulting in fluctuations in the collected data and affecting the accuracy of data collection

Moreover, it is also difficult to better meet the space requirements for internal top loading, and it is also inconvenient in terms of disassembly and maintenance.
