Description
Technical Field
The invention belongs to the field of protection of ship structures, and particularly relates to a protection structure resisting underwater explosion impact.
Background
The large surface ship is used as an important platform for sea operation, is used for maintaining the blue territory of China against invasion and realizing the basic guarantee of ocean strong country, but the large surface ship is a key striking target in sea operation due to high manufacturing cost and huge tactical and strategic values, and also provides extremely high requirements for the vitality of the large surface ship; for naval vessels, the destructive power of underwater explosive weapons such as torpedoes, mines and the like is larger than that of air explosive weapons such as conventional missiles, bombs, cannonballs and the like, and the naval vessels are more seriously damaged when being attacked by underwater weapons such as torpedoes, mines and the like, so that how to prevent underwater explosion impact damage becomes the key point of the anti-explosion and anti-impact research of large-scale water-surface ships;
the broadside protection structure of the large ship mainly aims at the protection of damage caused by contact explosion, and is designed to ensure that the local structural damage generated in the underwater contact explosion process of the ship can be controlled within an allowable range, protect various power equipment, electronic equipment, weapon equipment, personnel and the like in the ship from being damaged by explosion impact, and further ensure the vitality and the fighting capacity of the ship.
In the process of damaging ships by underwater explosion, the near-field structure is damaged by explosion impact and generates high-speed fragments, and the fragments fly to the inside of the ships and penetrate the rear structure, so that the core cabin of the ships is threatened. With the continuous improvement of modern explosive technology, the explosive power of the warhead of the weapon is gradually enhanced, fragments with higher speed and higher penetrating power are generated, and higher requirements are put forward on the protection capability of the protection bulkhead;
at present, a core structure for defending high-speed fragment penetration in a ship broadside multi-cabin protection structure is a protection liquid cabin, and fragments are decelerated mainly through liquid in the cabin to absorb fragment energy; however, the space of the liquid tank is limited, the energy dissipation degree of the fragments is limited, the protection efficiency of a simple liquid tank structure is not ideal, the water hammer effect generated by the fragments and the cavitation jet flow act on the inner plate of the liquid tank to impact the inner plate of the liquid tank, and even damage such as plug perforation, petal tearing and the like can be generated; the underwater explosion can also generate extremely strong shock wave load, the shock wave is transmitted to the inner plate of the liquid cabin through a liquid medium in the liquid cabin and reflected to form sparse wave, so that negative pressure is generated on the liquid and cavitation bubbles are formed, the cavitation bubbles are collapsed near the inner plate of the liquid cabin to generate secondary impact, and a larger load is applied to the inner plate of the liquid cabin; the detonation air mass of underwater explosion can also cause large deformation of the external structure of the ship body in the expansion process, so that the inner plate of the liquid tank is bent towards the inside of the ship body to drive the liquid medium in the liquid tank to move, and great inertia force is applied to the outer plate of the liquid tank to cause large plastic deformation of the outer plate of the liquid tank; a typical liquid tank inner plate is usually a flexible large-thickness deformation plate, and occupies a large weight in a cabin, and the protection efficiency of a single liquid tank structure is not ideal, so that the design of a protection structure capable of reducing the deformation of the liquid tank inner plate or reducing the weight of the liquid tank inner plate on the premise of a considerable protection effect has become a problem to be solved urgently.

In this embodiment, the buffer medium in the buffer cavity 6 is different from the filling medium in the cylinder 7, the wall thickness of the cylinder 7 is a thin-walled cylinder of 5-15mm, the impact resistance is improved on the premise of reducing the quality, and the filling medium in the cylinder 7 is liquid or air; the buffer medium in the buffer cavity 6 is liquid or air; the filling liquid can be fresh water, seawater or diesel oil.
In this embodiment, both ends of each cylinder 7 are connected to the transverse bulkheads on both sides of the ship, and the circle center distances between every two adjacent cylinders 7 are equal, so that the overall structural strength is improved.
In this embodiment, the quantity of diaphragm 8 is two at least and the interval distance equals, and the distance equals between every two adjacent transversal ribbed slab 4, and the distance equals between every two adjacent vertical purlins 5, through the mode that evenly sets up, can promote overall structure intensity's homogeneity and stability.
In the embodiment, the side outer plate 1, the liquid tank outer plate 2, the liquid tank inner plate 3, the transverse rib plates 4, the longitudinal girders 5, the cylinders 7 and the transverse partition plates 8 are subjected to rust prevention treatment, so that the strength and the reliability are prevented from being influenced by corrosion in an underwater environment.
When the liquid tank inner plate 3 is damaged, explosion shock waves are transmitted through a water medium in the buffer cavity 6, are blocked by the structure of the cylinder 7 in the buffer cavity 6, are reflected on the surface of the cylinder 7 and generate energy transmission, and further attenuate the energy of the explosion shock waves, and the reflected waves are reflected for multiple times in the transmission process of the buffer cavity 6, particularly near a slit region between the cylinders 7, so that the energy is greatly attenuated, and the shock wave load transmitted to the liquid tank inner plate is greatly reduced;
in the explosion impact process, the side outer plate 1 close to the explosion point generates high-speed fragments under the action of detonation, the energy of the high-speed fragments is consumed by the resistance of liquid after penetrating through the liquid tank outer plate 2 and entering the buffer cavity 6, and the high-speed fragments can also impact a hollow thin-wall circular tube structure in the buffer cavity 6 and generate a rebound or penetration process, so that a large amount of kinetic energy is consumed, and further, the liquid tank inner plate 3 cannot be damaged seriously enough; the high-speed fragment can generate water hammer effect and generate pressure wave when penetrating the liquid cabin, and the cylinder 7 positioned in the center of the buffer cavity 6 also can absorb and attenuate the pressure wave and shock wave load generated by the high-speed fragment in the liquid.

The diameter of the cylinder 7 is 20% -40% of the maximum width of the buffer cavity 6 along the ship width direction, so that the liquid layer in the buffer cavity 6 has sufficient width, and the cylinder 7 has sufficient collapse energy absorption effect.
The distance between the centers of two adjacent cylinders 7 is 120-160% of the diameter of the cylinders 7, so that the structural weight of the thin-wall circular tube is not too large, and the gap is sufficiently small so as not to enable the explosion shock wave to directly pass through the gap between the cylinders 7 and reach the inner plate 3 of the liquid tank.
The total height of a number of said cylinders 7 amounts to at least 80% of the height of the buffer chamber 6, ensuring that a sufficiently high shock wave barrier is formed in the liquid in the tank.
