Outer cabin structure for underwater vehicle

Abstract

The invention discloses an outer cabin structure for an underwater vehicle. The outer cabin structure comprises a shell and a hard frame, the whole shell is of a flat transverse hexagonal prism-like structure; the two V-like end parts of the transverse hexagonal prism-like structure respectively form a bow part and a stern part; a protruding skirt edge is annularly arranged on the peripheral face of the shell in the horizontal direction; and the hard frame is detachably arranged in the middle of the shell. Through the structural design of the shell, the rolling stability can be obviously improved on the premise of improving the lift-drag ratio, and the accuracy of data acquisition is ensured. Moreover, the unmanned aerial vehicle further has the advantages of higher sailing maneuverability, higher lift-drag ratio, certain restoring force during unexpected pitching and the like, propulsion or control energy can be saved, and the endurance mileage is increased. And the space requirement of internal carrying can be met as much as possible, modular design is integrally achieved, overall unloading and hoisting are facilitated, and maintenance and replacement are convenient. And meanwhile, the hard frame can also play a supporting role and is used for enhancing the mechanical strength of the whole structure and resisting larger external pressure.

Description

technical field [0001] The present application relates to the technical field related to underwater navigation, 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 the ocean economy, the research and development of underwater unmanned vehicles have received more and more attention. According to 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 close-range detection and underwater acquisition and maintenance, 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 related de...

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.
