The explosion venting device can replace the existing shipboard absorption liquid tank structure, namely a cabin protection design mode is redesigned, and the test sample piece is specifically analyzed by a large ship and can be adjusted along with different ship sizes. Can realize high-speed shell fragment and strike the protection, and absorb the interior arc plate of liquid cabin and support 7 and be equipped with explosion venting hole, can uninstall the shock wave, absorb the liquid cabin rear bulkhead and be compound liquid cabin inner panel structure 8, further improve the barrier propterty of the powerful protective bulkhead structure of topside when receiving typical underwater contact explosion effect. In the embodiment, the composite liquid tank inner plate structure 8 is a liquid tank inner plate.

As shown in fig. 1, it can be seen that the explosion vents are arranged at equal distances on the absorption tank, the diameters of the explosion vents at the bilge part can be properly reduced to ensure the structural strength, and the other function of the explosion vents is to ensure the fluid flow inside the tank to better resist the impact load. As shown in fig. 2, the plate frame support is arranged in the absorption liquid tank, the plate frame is composed of a liquid tank outer plate 2 and a composite liquid tank inner plate structure 8, and is welded between the liquid tank outer plate 2 and the composite liquid tank inner plate structure 8, the opening is smooth in transition, stress concentration is reduced, the overall strength of the plate frame can be seriously affected when the opening span is large, the support effect cannot be effectively realized, and the opening span of 1/5 plate frames is suitable.
