Small oil-filled full-scale deflection vector propeller thruster

Abstract

The invention discloses a small oil-filled full-scale deflection vector propeller thruster which comprises a propeller, a propulsion motor, a deflection mechanism, a rotary motor, a swing motor, a sealed cabin and a tail tube, wherein the propeller is connected with the propulsion motor so as to form a tail thruster, the rotary motor and the swing motor are respectively connected with the deflection mechanism so as to form a deflection system, the tail thruster and the deflection system are respectively connected with the tail tube of the thruster so as to form the full-scale deflection vector propeller thruster, and the full-scale deflection vector propeller thruster is arranged on a sealed cabin of an underwater vehicle so as to provide a vectored thrust for the underwater vehicle. Under the common driving of the rotary motor and the swing motor, the tail thruster can obtain the swing at a swivel angle of between minus 30 degrees and plus 30 degrees. The inside of the deflection mechanism is filled with oil, which not only solves the seal problem of the deflection mechanism, but also can lubricate the deflection mechanism and prevent mechanical parts in the deflection mechanism from water corrosion. The small oil-filled full-scale deflection vector propeller thruster disclosed by the invention has the advantages of compact structure, small volume, light weight, high efficiency, low cost and the like, and is suitable for providing the vectored thrusts for small underwater vehicles.

Description

technical field [0001] The invention relates to a small oil-filled full-deflection vector propeller propeller, which belongs to the technical field of marine engineering. It controls the cruise and attitude of the underwater vehicle by changing the angle between the axis of the propeller and the axis of the underwater vehicle to generate thrust in a specified direction. Background technique [0002] The propulsion system is the main component of the underwater vehicle, which is composed of two parts, the power plant and the propeller. Propellers mainly include: ordinary propellers, ducted propellers, counter-rotating propellers and water jet propellers. The ducted propeller is an annular casing with a longitudinal section that is airfoil-shaped or a broken line similar to the section of the airfoil on the periphery of the propeller. The casing can create a flow field that is conducive to the operation of the propeller and at the same time act as a part of the thruster. It ...
