The invention relates to the field of underwater propellers, in particular to an underwater propeller sealing structure for seabed operation, which comprises a mounting cabin, one end of the mounting cabin is connected with a pushing head, a sealing cabin is coaxially connected in the mounting cabin, and a driving shaft for driving the pushing head penetrates out of the sealing cabin. A sealing end for sealing is jointly connected among the mounting cabin, the sealing cabin and the pushing head; according to the sealing device, through cooperation of the clamping spring, the damping bag, the suspension block, the buffer cushion, the limiting abutting block, the abutting spring and other components, the influence of friction force, centrifugal force, radial run-out and axial movement on the sealing block during rotation of the driving shaft is effectively offset, and it is guaranteed that the sealing block is always attached to the surface of the driving shaft under different working conditions; abnormal deformation and abrasion are avoided, and the service life of the sealing block is prolonged.
本发明涉及水下推进器领域,特别涉及一种海底作业用水下推进器密封结构,包括安装舱,安装舱的其中一端连接有推动头,安装舱内还同轴连接有密封舱,密封舱内穿出有用于驱动推动头的驱动轴,安装舱、密封舱和推动头之间共同连接有用于密封的密封端;本发明通过卡紧弹簧、阻尼囊、悬块、缓冲垫、限位抵块和抵压弹簧等部件之间的协同配合,有效抵消了驱动轴转动时对密封块的摩擦力、离心力以及径向跳动和轴向窜动的影响,保证了密封块在不同工况下始终紧贴驱动轴表面,避免了异常形变和磨损,延长了密封块的使用寿命。
