The invention relates to a multistage self-floating cabin recovery device for a blasting test. The multistage self-floating cabin recovery device comprises a cabin body, a self-floating assembly and an inflation assembly, the self-floating assembly comprises a floating body and an air bag, one end of the air bag is connected with the floating body, the other end of the air bag is connected with the inner top wall of the cabin body, and the floating body can move out of the cabin body through the blasting opening after water enters the cabin and drive the air bag to move to abut against the inner side wall of the cabin body. The air inflation assembly is used for inflating the air bag; the cross section of the air bag in the inflated state is larger than the size of the blasting opening of the cabin body. After an explosion source is exploded, the floating body is moved out of the cabin body, and the buoyancy of the floating body plays a role in buffering sinking of the cabin body; meanwhile, the air bag is inflated to generate large buoyancy, a part of water in the cabin body is squeezed out along with pulling of the floating body, a floating thrust is applied to the cabin body by blocking the explosion opening, the cabin body can automatically float to the water surface, the cabin body can automatically float through the multi-stage structure of the floating body and the air bag, and recycling is convenient.
本发明涉及一种爆破测试用多级自浮式舱室回收装置,包括舱室本体、自浮组件和充气组件;自浮组件包括浮体和气囊,气囊一端与浮体连接,气囊另一端与舱室本体的内顶壁连接,浮体可在舱室进水后通过爆破口移动至舱室本体外,并带动气囊移动至与舱室本体的内侧壁抵接;充气组件用以对气囊充气;气囊在充气状态下的横截面大于舱室本体的爆破口的大小。本发明在爆源爆破后,浮体移出舱室本体外,自身的浮力对舱室本体的下沉起到缓冲作用;同时气囊充气产生较大的浮力,并随着浮体的拉动将舱室本体中的一部分水挤出、堵在爆破口处施加给舱室本体一个上浮的推力,使舱室本体自浮至水面上,浮体和气囊的多级结构可使舱室本体自浮,回收方便。
