A tail rudder of an underwater vehicle

Abstract

The invention discloses a tail rudder of an underwater vehicle, which comprises a housing, a steering gear, a steering gear mounting plate, a tail wing plate, a steering gear plate shaft, a steering gear plate, a bevel gear and a steering gear shaft. Three steering gear lug plates and three rudder shaft lug plates are uniformly arranged at equal distances in the housing; three rudder platforms arearranged on the outside, and rudder shaft lug plates are arranged on the inside of the rudder platforms; the steering mounting plate is screwed on the steering gear lug plate, and three groups of steering gears are arranged on the steering gear mounting plate; at that out end of the rudder platform and the steering gear plate bevel gear, a flap rudder is arranged; and at the outer end of the rudder platform and the rudder plate bevel gear, a flap rudder is arranged. The steering gear bevel gear and the rudder plate bevel gear are mutually meshed and driven. The invention adopts a three-axis rudder tail rudder arrangement mode, which saves cost and improves system reliability. The control model is simplified and the control difficulty is reduced; it has compact structure and high stability. The rudder plate adopts the flap structure to improve the rudder efficiency and the attitude control ability of the underwater vehicle. The electromagnetic interference is reduced, the stress structure of the rudder shaft is improved, the damage probability of the rudder shaft caused by the trailer is reduced, and the safety of the rudder shaft is improved.

Description

technical field [0001] The invention relates to the field of marine engineering underwater vehicle technical equipment, in particular to an underwater vehicle tail rudder. Background technique [0002] At present, human beings are facing three major problems of population, resources and environment. The ocean provides hope for human beings to solve these problems because of its abundant resources. Due to the limited depth of human diving and the harsh and dangerous underwater environment, as an important tool for ocean exploration and development, underwater self-propelled vehicles have broad application prospects in marine scientific investigations, marine environment monitoring, and marine resource exploration. A robot that works in extreme underwater operations. [0003] Intelligent underwater vehicles need to adapt to complex ocean environments, and their carriers must not only be pressure-resistant, watertight, and load-bearing, but also have low resistance, high prop...

Problems solved by technology

[0005] In the prior art, the tail rudder is generally installed on the tail section of the robot to ensure the safety of navigation and good operability. The "ten" rudder is the main one, and there are also some special "wooden" rudders and "rice" rudders; its disadvantages are complex structure, poor stability, and insufficient space movement ability
