The invention provides a submersible ballast device. The submersible ballast device comprises a submersible body and a ballast assembly. The opening of the tail frame of the submersible main body is formed in the bottom of the submersible main body; the submersible main body is connected with a winding and unwinding winch and a chain; the chain winds a turntable end of the winding and unwinding winch; the ballast assembly comprises a shell, lead sand and an air bag; the top of the shell is connected to one end of the chain and pulled back towards the tail frame along with retraction of the chain. The lead sand is contained in the shell and located in the shell, at the moment, the lead sand dives into water along with the shell or is pulled back to the tail frame, and the lead sand does not need to be separated from the shell when the ballast assembly is in the underwater environment and does not need to be loaded when the ballast assembly is pulled back to the tail frame; the air bag is arranged at the bottom of the shell and expands in the inflated state, the buoyancy of the ballast assembly is increased in the expanded state, when the ballast assembly needs to be pulled back to the tail frame, the air bag is in the expanded state, the floating area of the air bag in the expanded state is large, and large buoyancy is provided for the ballast assembly.
本申请提供一种潜水器压载装置,包括潜水器主体、压载组件;潜水器主体的尾部架的开口设置于潜水器主体的底部;潜水器主体连接有收放绞车和链条,链条缠绕收放绞车的转盘端;压载组件包括壳体、铅砂、气囊;壳体的顶部连接于链条的一端,并随着链条的收回而朝向尾部架回拉;铅砂容纳于壳体,并处于壳体内,此时,铅砂随壳体潜入水下或者回拉至尾部架,铅砂在压载组件处于水下环境时不需要脱离壳体,并且在压载组件回拉至尾部架时不需要装载;气囊设置于壳体的底部,并在充气状态下膨胀,且在膨胀状态增加压载组件的浮力,其中,在压载组件需要回拉至尾部架时,气囊处于膨胀状态,并且处于膨胀状态的气囊的浮动面积较大,向压载组件提供较大的浮力。
