The invention discloses a magnetic telescopic underwater paddle type propeller which comprises a stator, a rotor and a motor part. The motor part comprises a motor, a shell, a shaft and magnets, wherein the motor is arranged in the shell, the motor is connected with the shaft, and when the motor rotates, the shaft rotates along with the motor. The stator is fixedly connected with the shell, the stator is in a hollow ring shape, and the shaft penetrates through the hollow position of the stator. The rotor is fixedly connected with the shaft, a plurality of cavities are formed in the rotor, paddles are arranged in the cavities, permanent magnets are arranged at the bottoms of the paddles, and sheet-shaped parts of the paddles can extend out of the rotor. The two magnets are arranged above and below the stator respectively, the magnetism of the magnet arranged above the stator is opposite to the magnetism of the permanent magnets arranged at the bottoms of the paddles, and the magnetism of the magnet arranged below the stator is the same as the magnetism of the permanent magnets arranged at the bottoms of the paddles. By adopting a magnetic telescopic structure, the paddles can automatically extend and retract, so that the paddle type propeller can be applied underwater.

    本发明公开了一种磁伸缩水下桨式推进器,包括定子、转子和电机部,其中,电机部包括电机、外壳、轴和磁铁,电机设置在外壳中,电机与轴连接,电机转动,轴跟随转动;所述定子与外壳固定连接,定子为空心环状,轴穿过定子的空心处;所述转子与轴固定连接,转子中设置若干空腔,空腔内设置桨片,桨片的底部设置永磁铁,桨片的片状部位能够伸出转子;所述磁铁为两瓣,分别设置在定子的上方和下方,设置在定子上方的磁铁的磁性与桨片底部设置的永磁铁磁性相反,设置在定子下方的磁铁的磁性与桨片底部设置的永磁铁磁性相同。本发明采用磁伸缩结构,叶片能够自动伸出和缩回,使得桨式推进器能够应用于水下。
