The invention discloses a folding type multifunctional small shaftless propelling device which comprises a shaftless propeller, a connecting shaft and variable frequency driving equipment. The shaftless propeller is fixedly connected with the outer end part of the connecting shaft and is used for propelling; the connecting shafts are installed on the two sides of the ship body and used for rotating the shaftless propeller. And the variable frequency driving equipment is mounted in the ship and is used for controlling the rotating speed of the shaftless propeller. According to the device, a traditional tail propeller propelling mode can be expanded to a middle vector rim propelling mode, the device can be folded and stored, diversification of power functions is achieved, the sound stealth performance and the maneuvering performance are improved, and electric propelling transformation can be conducted on an existing ship.
本发明公开了一种折叠式多功能小型无轴推进装置,包括无轴推进器、连接轴、变频驱动设备;所述无轴推进器与连接轴外端部固定连接,用于推进;所述连接轴安装于船体两侧,用于转动无轴推进器;所述变频驱动设备安装在舰船内部,对无轴推进器进行转速控制。上述装置能够传统的尾部螺旋桨推进方式扩展到中部矢量轮缘推进型式,可折叠收纳,实现了动力功能的多样化,提高了声隐身性能和机动性能,可对现有舰船进行电力推进改造。
