The invention provides an underwater thruster capable of measuring water flow pressure and having thrust compensation. The underwater thruster comprises a thruster sealing shell, a front sealing cover, a rear sealing cover, a driving motor, a propeller, a pressure sensor mounting frame and a pressure sensor. The invention further provides a control method of the underwater propeller capable of measuring the water flow pressure and having the thrust compensation function. The pressure sensor is arranged in the propeller sealing shell, when the flow speed or direction of water flow changes and impacts the propeller, the driving motor slightly slides on the sliding rail, and then thrust acts on the pressure sensor through the driving motor and the pressure sensor mounting frame; the thrust is detected by the pressure sensor in real time and fed back to the controller, the controller compares the real-time thrust with the target thrust needing to be output and controls the driving motor to adjust the rotating speed, the actual thrust is made to be matched with the target thrust, and therefore stable sailing of the submersible is achieved.
本发明提供了一种可测水流压力且具有推力补偿的水下推进器,包括推进器密封外壳、前密封盖、后密封盖、驱动电机、螺旋桨、压力传感器安装架和压力传感器。本发明同时还提供可测水流压力且具有推力补偿的水下推进器的控制方法。本发明通过在推进器密封外壳内设置压力传感器,当水流流速或方向变化冲击到螺旋桨时,会导致驱动电机在滑轨上产生微小滑动,进而推力会通过驱动电机和压力传感器安装架作用到压力传感器上,推力会实时地被压力传感器检测并反馈给控制器,控制器根据实时推力与需要输出的目标推力进行比较,控制驱动电机调整转速,使实际推力与目标推力相匹配,从而实现潜水器的平稳航行。
