The invention relates to the technical field of ship manhole sealing, and discloses a marine manhole sealing protection device, a manhole cover plate base is mounted above a manhole, and a cover plate support is arranged at the bottom of the base. A shell is arranged on the base, and a driving mechanism is arranged in the shell. The mechanism comprises a lower plate, a vertical plate, an upper plate, a hydraulic motor, a belt wheel I, a belt wheel II, a screw rod, a nut seat, a connecting seat, a clamping sleeve, a lifting sleeve, a fixed pipe seat, a sliding sleeve and a pressing rod. The hydraulic motor drives the first belt wheel, the second belt wheel is driven by the belt to rotate, the second belt wheel drives the screw to rotate, the nut seat moves along the screw, the linkage seat and the clamping sleeve move along with the screw, the lifting sleeve slides in the fixed pipe seat, and the pressing rod ascends and descends to control the manhole cover plate. The driving mechanism achieves accurate control over the screw through a hydraulic motor and a belt transmission system, and then the lifting sleeve and the pressing rod are driven to do lifting motion in the vertical direction. The tedious process of traditional manual operation is simplified, and the sealing efficiency and reliability are remarkably improved.
本发明涉及船舶人孔密封技术领域,公开了一种船用人孔密封防护装置,人孔盖板基座安装于人孔上方,基座底部有盖板支架。基座上设有外壳,内装驱动机构。机构包括下板、立板、上板、液压马达、带轮一、带轮二、螺杆、螺母座、联座、夹套、升降套管、固定管座、滑套和压杆。液压马达驱动带轮一,通过皮带带动带轮二旋转,带轮二带动螺杆旋转,螺母座沿螺杆移动,联座和夹套随之移动,升降套管在固定管座内滑动,压杆升降以控制人孔盖板。驱动机构通过液压马达和皮带传动系统,实现了对螺杆的精确控制,进而带动升降套管及压杆进行垂直方向的升降运动。不仅简化了传统手动操作的繁琐流程,还显著提高了密封的效率和可靠性。
