The invention provides an underwater navigation power device. The underwater navigation power device comprises a pressure-resistant cabin, a sealing end cover, a sealing connector and a driving motor,an opening is formed in the front part of the pressure-resistant cabin; the sealing end cover is fixedly arranged at the opening part of the pressure-resistant cabin through threaded connection; a through hole is formed in the axis of the sealing end cover and used for allowing a power shaft of the aircraft to be inserted into the pressure-resistant cabin from the outside, and a movable sealing piece is arranged between the sealing cavity and the power shaft. A threading hole is formed in the pressure-resistant cabin, the sealing connector is fixedly arranged on the threading hole through threaded connection, and the middle shaft part of the sealing connector is hollowed out; the driving motor is fixedly arranged in the pressure-resistant cabin, and an output shaft of the driving motor isin transmission connection with the power shaft through a coupler. The underwater vehicle power device solves the technical problems that an existing underwater vehicle power device is complex in structure and does not have good sealing performance, and the power device is directly soaked in a water area all the year round, so that the device is corroded, and the service life of the whole deviceis seriously affected.

    本申请提供了一种水下航行动力装置,包括:耐压舱、密封端盖、密封连接头和驱动电机;耐压舱的前部开口,密封端盖通过螺纹连接固定设置于耐压舱的开口部位;密封端盖的轴心部位开设有贯穿孔,用于使航行器的动力轴从外部插入至耐压舱内,密封腔与动力轴之间设置有动密封件;耐压舱上开设有穿线孔,密封连接头通过螺纹连接固定设置于穿线孔上,密封连接头中轴部镂空;驱动电机固定设置于耐压舱的内部,驱动电机的输出轴通过联轴器与动力轴传动连接。本申请解决了现有的水下航行器动力装置结构复杂,不具有良好的密封性,动力装置常年累月直接浸泡在水域中,导致装置出现腐蚀现象,严重影响整个装置的使用寿命的技术问题。
