The invention belongs to the field of ocean observation, and particularly relates to an underwater large-tension release mechanism which comprises a release hook, an underwater motor and a pull rope, the release hook comprises a hook body, an opening and closing lip and an opening pull rod, and the underwater motor comprises a sealing device, a direct current motor, a pressure buffering device, a connecting shaft, a nylon block and a watertight connector; the sealing device comprises a cylinder, a left end cover and a right end cover; the pressure buffering device comprises a through rod, a hoop and a rubber pipe. The release lifting hook is connected with the underwater motor through a pull rope, the direct current motor controls the connecting shaft to rotate so as to enable the nylon block to move in the axial direction, and after the nylon block is separated from the connecting shaft and released, the tension spring pulls the opening pull rod to enable the opening pull rod to rotate upwards so as to enable the pull lining plate and the opening and closing lip to be in linkage, so that the hanging hole is opened, and a heavy object is released. The underwater large tension release device is easy to manufacture, exquisite in structure, high in overall strength and capable of achieving underwater large tension release.
本发明属于海洋观测领域,具体地说是一种水下大拉力释放机构,包括释放吊钩、水下电机和拉绳,释放吊钩包括吊钩主体、张闭唇和打开拉杆,水下电机包括密封装置、直流电机、压力缓冲装置、连接轴、尼龙块及水密接插件;密封装置包括圆筒、左端盖及右端盖;压力缓冲装置包括贯通杆、卡箍及胶管。释放吊钩与水下电机通过拉绳相连,直流电机控制连接轴转动继而使尼龙块沿轴向移动,当尼龙块脱离连接轴释放后,通过拉簧拉动打开拉杆,使打开拉杆向上转动,进而使拉衬板和张闭唇发生联动,从而使悬挂孔张开,实现重物的释放。本发明制作简单,结构精巧,整体强度高,能实现水下大拉力释放。
