A disc-shaped underwater vehicle based on vortex motion

Abstract

The invention discloses a disc-shaped underwater vehicle based on vortex motion. A disc-shaped fairing is adopted. At least one circumferential propeller is arranged in the circumferential direction of the disc-shaped fairing. A vortex generating mechanism and at least one vertical propeller are arranged in the vertical direction of the disc-shaped fairing. The circumferential propellers are used for driving the motion of the vehicle in the horizontal plane of the disc-shaped fairing. The vertical propellers are used for driving the motion of the vehicle in the vertical direction of the disc-shaped fairing. The vortex generating mechanism is used for generating adsorption force relative to the absorption surface. According to the novel technology for achieving object surface absorption based on a vortex adsorption mechanism, the underwater vehicle is made to have high surface adsorption capacity; through the cooperation of the impelling action of the propellers, the vehicle has the omni-directional motion capacity including crawling and swimming, and compared with an existing crawling or swimming underwater vehicle, the disc-shaped underwater vehicle has the advantages that the sailing speed is high, and motion control is swift. An acquisition sensor and operation tools are carried as needed, and the disc-shaped underwater vehicle can be used for carrying out underwater engineering detection, emergency searching, construction operation and the like.

Description

technical field [0001] The invention belongs to the field of marine survey and monitoring, in particular to a dish-shaped underwater vehicle based on vortex motion. Background technique [0002] Autonomous underwater vehicle integrates sensing, communication, navigation, control, energy, propulsion and other technologies. It is one of the most cutting-edge technologies developed in the field of international ocean engineering in the past two decades. The advantage of high autonomy has become an important tool for three-dimensional dynamic observation of the marine environment in recent years. [0003] Existing autonomous underwater vehicles usually have two typical locomotion forms: parade and crawl. Most of the parade underwater vehicles are slender and streamlined, and are in a state of neutral buoyancy or slightly positive buoyancy during movement. Some use propellers and control rudders for driving and attitude adjustment respectively. Regulating mechanism and center o...

AI Technical Summary

Problems solved by technology

It is difficult for existing autonomous underwater vehicles to have high-speed, agile parade and crawling capabilities at the same time, and the surface adsorption capacity that can be provided is limited and limited by the application, so it is difficult to perform fast and accurate target search and underwater load operations.
