The invention relates to the technical field of submersibles, in particular to a shearing device automatically releasing a buoyant raft. The device comprises an enclosure frame, a mounting mechanism for mounting the enclosure frame on a submarine is fixed on the enclosure frame; a glue pressing block capable of floating up and down is arranged in the enclosure frame; a rubber block is loaded between the upper end of the glue pressing block and the enclosure frame; a roller capable of rotating freely is fixed on the enclosure frame through a mounting frame; a horizontal shearing bolt is inserted and fixed in the glue pressing block; the head of the shearing bolt is clung to the rolling surface of the roller; the other end of the shearing bolt is mounted on the buoyant raft; an annular groove is formed in a shaft body of the shearing bolt in the circumferential direction. A shearing plate is fixed on the enclosure frame; a strip-shaped hole is formed in the shearing plate, the hole length direction is the vertical direction, the shearing bolt vertically penetrates through the strip-shaped hole, when the shearing bolt floats upwards, the peripheral wall of the shearing bolt located between the annular groove and the glue pressing block can abut against the inner wall of the upper end groove of the strip-shaped hole, and the shearing bolt is automatically sheared off through buoyancy borne by the buoyant raft when a submarine dives.

    本发明涉及潜水器技术领域,尤其是一种自动释放浮筏的剪切装置,包括围框,围框上固定有用来将围框安装在潜艇上的安装机构,围框内布置可上下浮动的压胶块,压胶块的上端和围框之间填塞橡胶块,围框上通过安装架固定有可自由转动的滚轮,压胶块中穿插固定水平的剪切螺栓,剪切螺栓的头部贴靠在滚轮的滚面上,剪切螺栓的另一端安装在浮筏上,剪切螺栓的轴身上沿周向开设环形槽,围框上固定剪切板,剪切板上开设条形孔且孔长方向为竖直方向,剪切螺栓自条形孔中垂直穿过,当剪切螺栓上浮时,位于环形槽和压胶块之间的剪切螺栓的外周壁能够抵靠在条形孔的上端槽内壁上,靠潜艇下潜时浮筏自身所受到的浮力自动剪断剪切螺栓。
