The invention discloses an underwater vector propelling device based on a shaftless rim type propeller. The device comprises a shaftless rim type thruster, a vector deflection mechanism and a sealing mechanism, the device is installed at the tail of a shell of the autonomous underwater vehicle, the sealing mechanism is installed in the tail of the shell, the vector deflection mechanism is hinged between the sealing mechanism and the shaftless rim type thruster, and the shaftless rim type thruster is located outside a port of the tail of the shell. The shaftless rim thruster is used for replacing a traditional guide pipe type propeller, the number and complexity of mechanical parts are reduced, the wet cabin space occupied by the device is greatly reduced, the internal layout of the AUV is effectively improved, and the stability of the AUV during navigation is improved; the vector deflection mechanism is compact in structure and easy to control, the problems that in the prior art, the vector deflection angle is small, the structure is complex, and the size and weight are large are solved, the vector deflection mechanism drives the shaftless rim propeller to deflect by +/-30 degrees in the horizontal direction and the vertical direction, and then the maneuverability and flexibility of the AUV are improved.
本发明公开了一种基于无轴轮缘式推进器的水下矢量推进装置。装置包括无轴轮缘式推进器、矢量偏转机构和密封机构,装置安装在自主式水下航行器的外壳尾部,密封机构安装在外壳尾部内,矢量偏转机构铰接在密封机构和无轴轮缘式推进器之间,无轴轮缘式推进器位于外壳的尾部端口外。本发明利用无轴轮缘推进器替代传统的导管式螺旋桨,减少了机械部件的数量和复杂度,大幅减少了装置占用的湿舱空间,有效改善了AUV的内部布局,提高了AUV航行时的稳定性;本发明结构紧凑,易于控制,解决了现有技术中矢量偏转角度小、结构复杂、体积重量大的问题,矢量偏转机构带动无轴轮缘推进器实现水平和竖直方向上±30°的偏摆,继而提升AUV的机动性和灵活性。
