The invention provides a blade folding device for an underwater propeller thruster, the blade folding device comprises a rotating base and two blade assemblies mounted on the rotating base through a folding shaft, and the rotating base is used for being connected to a power output end of a driving motor and can be driven by the driving motor to rotate forwards or reversely; the two paddle assemblies are oppositely arranged on the two sides of the rotating axis of the rotating base. Each paddle assembly comprises a paddle and a folding wheel arranged at the end of the paddle, each folding wheel comprises a gear part, and the gear parts of the two folding wheels are meshed with each other. By the adoption of the technical scheme, the paddles can be rapidly folded and unfolded only through driving of the driving motor; meanwhile, the folding state locking devices and the gear parts meshed with each other are arranged on the two paddles, so that the two paddles cannot swing under the acting force of the water flow, and the two paddles cannot be separated by overcoming the constraint of the folding state locking devices under the acting force of the water flow.

    本发明提供了一种用于水下螺旋桨推进器的桨叶折叠装置,包括旋转基座以及通过折叠轴安装于旋转基座上的两个桨叶组件,所述旋转基座用于连接至驱动电机的动力输出端并能够通过驱动电机的驱动而正转或反转;两个所述桨叶组件相对设置于所述旋转基座的旋转轴线两侧;每个所述桨叶组件包括桨叶以及设置于桨叶端部的折叠轮,所述折叠轮包括齿轮部,两个所述折叠轮的齿轮部相互啮合。采用上述技术方案,仅依靠驱动电机的驱动即可实现桨叶的快速折叠和展开;同时,在两个桨叶上设置有折叠状态锁紧装置和相互啮合的齿轮部,既能够保证两个桨叶均无法在水流的作用力下进行摆动,又能够保证两个桨叶不会在水流的作用力下克服折叠状态锁紧装置的束缚而分离。
