The invention provides a double-propeller type underwater propeller which comprises a tubular shell of a hollow structure, a stator assembly fixed in the tubular shell and a rotor assembly rotatably arranged in the tubular shell, a rotating shaft is arranged in the center of the rotor assembly, a front sealing cover and a rear sealing cover are arranged at the front end and the rear end of the tubular shell in a sealed mode respectively, the front sealing cover and the rear sealing cover are connected with the tubular shell in a sealed mode, the front end and the rear end of the rotating shaft penetrate through the front sealing cover and the rear sealing cover respectively, propellers are fixed to the penetrating ends, the two ends of the rotating shaft are rotatably connected with the front sealing cover and the rear sealing cover, a wire groove is formed in the upper portion of the tubular shell, an outer end plate is arranged at an outer groove opening of the wire groove in a sealed mode, a plurality of wire passing holes communicated with the interior of the tubular shell are formed in the wire groove, and the end of a power line is connected into the wire groove and electrically connected with the stator assembly through the wire passing holes. The rotating shaft drives the propellers at the two ends of the rotating shaft to rotate, so that larger power is provided, the structure is relatively simplified, the cost is reduced, the thrust is stronger, and the sealing and waterproof performance is good.

    本发明提供了一种双浆式水下推进器,包括中空结构的管状外壳、固定在管状外壳内的定子组件、以及可转动设置在管状外壳内的转子组件,转子组件的中心具有转轴,管状外壳的前后两端分别密封设置有前封盖和后封盖,前封盖和后封盖与管状外壳密封连接,转轴的前后端分别由前封盖和后封盖穿过,且穿过端均固定有螺旋桨,转轴的两端与前、后封盖可转动连接,管状外壳上方设有线槽,线槽外槽口处密封设置有外端板,线槽内具有多个与管状外壳内部连通的过线孔,电源线的端部接入线槽内,并经过过线孔与定子组件电连接。转轴带动其两端的螺旋浆转动,进而提供了更大的动力,结构相对简化,降低了成本,但推力更强劲且密封防水性能佳。
