Description

TECHNICAL FIELD

[0001] The utility model relates to ship technology field especially relates to a steel-aluminum composite ship body structure of ship. BACKGROUND

[0002] Ship hull technology, as the core of modern naval engineering, has undergone several centuries of development and innovation. From the early use of wood to build simple structure boats to today's high-performance ships made of high-strength steel, lightweight aluminum alloy and advanced composite materials.

[0003] But the inland river ships used in inland waterways, their hull structure is more slender compared to ocean ships, designed to reduce weight and construction costs while ensuring sufficient buoyancy and cargo space. But this design choice exposes obvious weaknesses when faced with the unique shoals and complex underwater topography of inland waterways. Due to the limited depth of the river, combined with the possibility of rocks, sandbars and other obstacles on the riverbed, the hull of the inland river ship is prone to scratches. Such contact is frequent and inevitable, often leading to hull dents or other forms of damage, threatening the safe operation and service life of the ship. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a steel-aluminum composite ship body structure of ship, which solves the technical problem that the hull of the inland river ship is prone to dents after being scratched by the river.

[0005] According to the steel-aluminum composite ship body structure of ship recorded in the embodiment of the utility model, the bottom and side of the ship are evenly distributed with convex ribs of sealing patterns, a layer of inner protective plates is arranged on the convex ribs, the convex ribs and the inner protective plates form a first layer of anti-collision chambers, the outer side of the inner protective plates is evenly distributed with convex strips of sealing patterns, a layer of outer protective plates is arranged on the convex strips, the convex strips and the outer protective plates form a second layer of anti-collision chambers.

[0006] The sealing patterns formed by the convex ribs and the sealing patterns formed by the convex strips are arranged in a staggered manner, a conical spring is arranged in each anti-collision chamber, the conical spring in the first layer of anti-collision chambers is aligned with the convex strips, the conical spring in the second layer of anti-collision chambers is aligned with the convex ribs, and the small end of the conical spring faces the outer side of the ship.

[0007] The technical principle of the utility model is that when the hull is scratched with the riverbed, the conical spring in the anti-collision chamber aligned with the scratch part will be elastically deformed due to the scratch, and when the scratch ends, the outer side inner protective plate or outer protective plate will be bounced back to the original state due to the elastic force of the conical spring, reducing the dents after the scratch. Of course, if the impact force of the scratch is too large, the anti-collision chamber is completely flattened and cannot be restored, which needs to be repaired.

[0008] Because the two layers of anti-collision chambers are arranged in a staggered manner, the hull bottom and both sides can be protected from damage by the conical springs.

[0009] Preferably, the conical springs can well absorb and distribute the impact force to the hull bottom or sides.

[0010] Compared with the prior art, the utility model has the beneficial effects that: through the two layers of anti-collision chambers arranged in a staggered manner and the conical springs in the anti-collision chambers, the technical problem that the river ship bottom is prone to concave after being scratched by a river is solved.

[0011] Further, the inner protection plate and the outer protection plate are made of aluminum material, and the raised ribs and the raised strips are made of steel material.

[0012] Further, the thickness of the outer protection plate is twice that of the inner protection plate.

[0013] Further, the raised ribs and the ship are provided with a circular arc corner, and the raised strips and the inner protection plate are also provided with a circular arc corner.

[0014] Further, the anti-collision chamber is provided with a ring-shaped protrusion near one side of the ship center, and the large end of the conical spring is clamped into the ring-shaped protrusion.

[0015] Further, the thickness of the ring-shaped protrusion is less than or equal to 1 / 2 of the thickness of the raised ribs or the raised strips.

[0016] Further, the ship is uniformly provided with watertight cabins, and the watertight cabins are provided with inner protrusions arranged in a staggered manner, and the intersections of the inner protrusions are aligned with the conical springs in the first layer of anti-collision chambers.

[0017] The impact force transmitted by the conical spring is borne by the inner protrusions, which helps to improve the impact resistance of the ship body.

[0018] Further, the sealing pattern is a rectangle, a regular hexagon or a regular triangle.

[0019] Further, the raised strips or the raised ribs at the inner corners of the sealing pattern are provided with a circular arc structure. BRIEF DESCRIPTION OF DRAWINGS

[0025] Example 1

[0026] like Figures 1-2 The steel-aluminum composite hull structure of the ship shown has evenly distributed rectangular raised ribs 210 welded to the bottom and sides of the ship 100. An inner protective plate 220 is welded and fixed to the raised ribs 210. The raised ribs 210 and the inner protective plate 220 form a first anti-collision chamber 200. Evenly distributed rectangular raised strips 230 are welded to the outside of the inner protective plate 220. An outer protective plate 240 is welded and fixed to the raised strips 230. The raised strips 230 and the outer protective plate 240 form a second anti-collision chamber 200.

[0027] like Figures 2-3 As shown, the sealing pattern formed by the raised rib 210 and the sealing pattern formed by the raised strip 230 are staggered. All anti-collision chambers 200 are equipped with conical springs 250. The conical springs 250 in the first anti-collision chamber 200 are aligned with the raised strip 230, and the conical springs 250 in the second anti-collision chamber 200 are aligned with the raised rib 210. The small end of the conical springs 250 faces the outside of the ship 100, so as to absorb the impact force generated during scraping to the maximum extent.

[0028] Specifically, the inner protective plate 220 and the outer protective plate 240 are made of aluminum, while the raised ribs 210 and the raised strips 230 are made of steel, providing corrosion resistance and excellent toughness respectively. The thickness of the outer protective plate 240 is twice that of the inner protective plate 220 to ensure that the outer protective plate 240, which is in direct contact with the riverbed, has sufficient strength.

[0029] like Figure 2 As shown, a rounded corner 211 is provided between the raised rib 210 and the ship 100, and a rounded corner 211 is also provided between the raised strip 230 and the inner protective plate 220. A rounded structure 231 is provided between the raised strip 230 or the raised rib 210 at the inner corner of the rectangle to prevent the raised strip 230 or the raised rib 210 from breaking during impact.

[0030] like Figure 2-3As shown, the anti-collision chamber 200 is welded with an annular protrusion 251 near the side close to the center of the ship 100, the large end of the conical spring 250 is clamped into the annular protrusion 251, the thickness of the annular protrusion 251 is less than or equal to 1 / 2 of the thickness of the protruding rib 210 or the protruding strip 230, and the annular protrusion 251 plays the role of the fiber conical spring 250.

[0031] As shown in the drawings, Figures 1-2 As shown, the ship 100 is evenly distributed with watertight cabins 110, and all the watertight cabins 110 are integrally formed with staggered inner protrusions 111, and the intersections of the inner protrusions 111 are aligned with the conical springs 250 in the first layer of anti-collision chambers 200.

[0032] Embodiment 2

[0033] The difference between this embodiment and embodiment 1 is that the sealing pattern is a regular hexagon or a regular triangle, which has better stability than the rectangular sealing pattern, but is more difficult to arrange than the rectangular arrangement.
