Abstract

The invention discloses a flat type underwater vehicle. The flat type underwater vehicle comprises a carrier, a control device and a propelling device. The carrier is a transversely-arranged shell which is flat on the whole and is of a similar hexagonal prism structure; a hard frame is detachably mounted in the shell; at least two independent cabins are detachably mounted in the hard frame; and the propelling device is installed on the shell. The control device comprises a control system and a navigation positioning matching system; the navigation positioning matching system is used for matching a navigation positioning mode according to task requirements and acquiring positioning information based on the navigation positioning mode; and the control system is used for controlling the underwater vehicle to sail based on the current underwater information, the positioning information and the navigation positioning mode. According to the invention, the rolling stability can be remarkably improved on the whole, the accuracy of data acquisition is ensured, meanwhile, the control system has the characteristics of high navigation precision, strong autonomous decision-making ability and good maneuverability, the endurance mileage is effectively increased, and the invention solves the technical problems of complex circuit arrangement, difficulty in disassembly and maintenance and high cost of a control system of an existing underwater vehicle are solved.

Description

technical field [0001] The present application relates to the technical field related to underwater navigation, in particular to a flat 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 detection equipment. Among...
