The invention belongs to the field of power devices, and discloses a propeller propelling device based on shape memory alloy. According to the device, a traditional propeller power device is abandoned, and the principle that the shape memory alloy can extend after being electrified and heated is utilized to drive a sliding rod to rotate, so that a propeller and a worm are driven to rotate, finally power is transmitted to the propeller, the propeller is driven by stretching and retracting of the shape memory alloy, original fuel oil driving or combustion driving can be replaced, consumption of electric energy can be reduced by adopting an intermittent power supply mode, pollution can be avoided, and the device has the advantages of being high in energy utilization rate, high in propelling efficiency and the like. Meanwhile, the structure is simple, operation and maintenance are easy, and the device can serve as a propelling device of small ships. Manpower consumption can be reduced, and the cost is reduced.

    本发明属于动力装置领域,公开了一种基于形状记忆合金的螺旋桨推进装置,摒弃了传统的螺旋桨动力装置,利用形状记忆合金通电加热会伸长的原理,来带动滑杆的转动,从而带动螺旋桨和蜗杆的转动,最终将动力传送至螺旋桨,利用形状记忆合金的伸缩来驱动螺旋桨,能够代替原有的燃油驱动或燃烧驱动,采用间歇性的供电方式能够减少电能的消耗,可以实现无污染,具备能源利用率高,推进效率高等优点。同时结构简单,易操作,易维护,可以作为小型船只的推进装置。能够减少人力的使用,降低成本。
