The invention relates to a position indicating mark for sinking equipment. The position indicating mark comprises a raft shell, an immersed breathable water inlet valve, a gas storage bottle, an automatic inflation valve, an inflatable air bag, a connecting rope and a rope storage winch. The raft shell comprises an upper raft shell and a lower raft shell which are connected into a whole through a connecting piece; at least two immersed breathable water inlet valves are fixed to the top of the upper raft shell, and the bottoms of valve shells are fixed to water surface equipment. If a water surface sinking accident occurs, after the position indicating mark of the sinking equipment is soaked in water, water enters the valve shell from the immersed breathable water inlet valve, after the water in the valve shell reaches a certain amount, the automatic inflation valve is started, the air storage bottle is opened to inflate the inflatable air bag, the inflatable air bag continuously expands to emerge from the water surface by means of the buoyancy of the inflatable air bag, and due to the traction effect of the connecting rope, the inflatable air bag is automatically inflated. And the inflatable air bag cannot drift at will, so that the sinking position of the water surface equipment can be effectively indicated.

    本发明涉及一种沉没设备示位标,示位标包括筏壳、浸没式透气进水阀、储气瓶、自动充气阀、充气式气囊、连接绳、储绳绞车;筏壳包括上筏壳及下筏壳,通过连接件连接成整体;浸没式透气进水阀数量至少为二只,固定在上筏壳顶部,阀壳底部与水面设备固定。若发生水面沉没事故,沉没设备示位标浸水后,水从浸没式透气进水阀进入阀壳,当阀壳内水达到一定量后,自动充气阀启动并打开储气瓶对充气式气囊充气,充气式气囊的不断胀大借助自身浮力浮出水面,由于连接绳的牵引作用,充气式气囊并不能随意漂移,进而可以有效的指示水面设备的沉没位置。
