Shock-resistant protective structure for ship

Abstract

The invention discloses a shock-resistant protective structure for a ship. The shock-resistant protective structure comprises an inner sandwich plate and an outer sandwich plate, wherein a sandwiched truss is arranged between the inner sandwich plate and the outer sandwich plate; the sandwiched truss consists of a plurality of longitudinal truss units; each longitudinal truss unit comprises truss plates which are arranged to form an angle with each other; the plurality of longitudinal truss units are uniformly distributed between the inner sandwich plate and the outer sandwich plate. Compared with the prior art, the shock-resistant protective structure for the ship has the advantages as follows: under the condition that the structural weights are the same, the size of a structural component is reduced, the shock resistance is greatly improved, and the problem that the structural shock resistance is improved by increasing the structural size and the number of structures is solved; under the condition that the same shock-resistant effect is achieved, reduction of the structural weight can be achieved, and the economic value is increased; quick assembly can be achieved through prefabrication, simplification of a construction process is achieved, and in the latter ship repair, quick repair can also be achieved by a module replacing method.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship anti-shock protection structure. Background technique [0002] With the continuous expansion of the shipping market, the number of ships at sea is increasing, and the ships are beginning to develop in large, high-speed, and large-tonnage, which will inevitably lead to frequent collisions and grounding accidents of ships. The side and bottom of the ship have strong collision resistance; and at present, the navies of various countries are vigorously developing maritime equipment forces, which are bound to be impacted by explosions during operations. The primary task of boat design. Therefore, whether it is a civilian ship or a military ship, in order to ensure the safety of personnel and equipment and prevent cargo leakage, high-performance impact-resistant protective structures must be used. [0003] For the hull structure, deformation and damage will inevitably occur after being imp...

AI Technical Summary

Problems solved by technology

These protective structures often improve the impact resistance by improving the original hull structure or adding some energy-absorbing components. These methods often increase the weight of the hull structure and sacrifice the economy of the ship.

If it is necessary to improve the impact resistance of the structure while controlling the weight of the structure, the superiority of these methods is not obvious enough
