The telescopic variable-pitch cross-medium propeller mechanism comprises a vane seat shell, a supporting frame is arranged in the vane seat shell, an electric telescopic rod assembly is arranged on the supporting frame, vane assemblies are connected to the left end and the right end of the electric telescopic rod assembly in a threaded mode, each vane assembly is formed by sleeving a plurality of multi-section vanes, and the vane seat shell and the electric telescopic rod assembly are connected in a threaded mode. The front end of the electric telescopic rod assembly is connected with a wing piece at the foremost end of the wing piece assembly, and the wing piece assembly is driven by the electric telescopic rod assembly to stretch and retract. Appropriate lift force is provided for the cross-medium aircraft or the aircraft, modular design is adopted, wing panel serialization design can be carried out according to the load requirement of the cross-medium aircraft or the aircraft, the wing panel extends into a large wingspan during air flight, the wing panel contracts into a small wingspan during underwater navigation, and the screw pitch of the propeller is increased.
本发明公开了一种可伸缩变距跨介质螺旋桨机构,包括翼片座壳体,所述翼片座壳体内部设置有支撑架,所述支撑架上设置有电动伸缩杆组件,所述电动伸缩杆组件左右两端螺接有翼片组件,所述翼片组件由若干个多节翼片套装而成,所述电动伸缩杆组件的前端与翼片组件最前端的翼片相连接,通过所述电动伸缩杆组件的驱动带动着翼片组件的伸长与缩短。本发明为跨介质飞行器或航行器提供合适升力,采用模块化设计,可根据跨介质飞行器或航行器载荷要求进行翼片系列化设计,空中飞行时翼片伸展为大翼展,水下航行时翼片收缩为小翼展并增大螺旋桨螺距。
