Flow guiding shield used for autonomous underwater vehicle

Abstract

The invention belongs to the field of autonomous underwater vehicle equipment, discloses a flow guiding shield used for an autonomous underwater vehicle and particularly relates to the flow guiding shield used in a propelling system of the autonomous underwater vehicle. A novel practical electrically-driven underwater thruster the application number of which is 200620055186.1 is disclosed in the prior art, and according to the underwater thruster, an axial section of the flow guiding shield is designed in a wing shape, so that the purposes of high efficiency and low power consumption are achieved, but which type of wings should be adopted is not specifically indicated in the prior art, and the defects of poor structural universality and a limited application range still exist. According tothe flow guiding shield, a wing type NACA6721 and a 3D printing technology are adopted for designing the flow guiding shield which is simple in structure and wide in application range, the inflow velocity is increased, the propelling force of propellers is enhanced, the efficiency of the propelling system is improved, vibration of the tail part of the propelling system is reduced, and a great protection function is achieved on the propellers. The flow guiding shield is structurally characterized in that the axial section of an outer shield body is the wing type NACA6721, the angle of attack is 10 degrees, and by adopting a spoke-type structure, not only is the intensity ensured, but also the flow guiding shield is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the field of autonomous underwater vehicle (AUV) equipment, in particular to the deflector in the propulsion system of the autonomous underwater vehicle (AUV), which is suitable for solving the problem of the deflector of the autonomous underwater vehicle (AUV). design issues and the efficiency of the propulsion system. Background technique [0002] As resources on land dwindle, people turn their attention to the vast ocean, which contains abundant clean energy such as combustible ice. my country successfully mined combustible ice in 2017, leading the world in mining technology. In the near future, the ocean will become the main development and utilization area for people, and autonomous underwater vehicles will become an important auxiliary tool in the development process. [0003] Compared with traditional underwater exploration tools, autonomous underwater vehicle (AUV) has the advantages of safety, high efficiency, large d...
