Abstract

The invention provides an autonomous underwater vehicle controlled by double propellers in a vector mode and provided with a foldable antenna. The autonomous underwater vehicle comprises an upper fairing and a lower fairing, the upper air guide sleeve and the lower air guide sleeve are connected to form a cabin body, a main cabin and power supply cabins arranged on the two sides of the main cabinare installed in the cabin body, a plurality of camera structures are arranged at the head of the main cabin, the tail part of the main cabin is connected with a tail part propelling mechanism, an antenna structure is arranged at the tail end of the main cabin, the tail propelling mechanism comprises propellers symmetrically arranged on the two sides of the tail of the cabin body, the two propellers are both connected with a first underwater steering engine which drives the two propellers to synchronously rotate on the vertical space plane and then adjust the pitching state, steering is controlled through the difference rotating speed of the two propellers, and the first underwater steering engine is installed in the cabin body and connected to a rear end cover of the main cabin.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, in particular to an autonomous underwater vehicle with double thruster vector control and foldable antennas. Background technique [0002] In recent years, with the development of marine engineering technology, autonomous underwater vehicles have been more and more widely used. Conventional autonomous underwater vehicles are propelled by tail propellers, and a tail rudder is added to control pitch and steering. This kind of rudder control method has a relatively large turning radius, and its maneuverability is coupled with the sailing speed. At low speeds, the steering effect of the rudder is not good or may even fail. In addition, there has been an autonomous underwater vehicle with single propeller vector control, which uses gimbals or other mechanisms to realize the vector swing of the tail propeller. Because its maneuverability is no longer coupled with the sailing speed, better...
