Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] like figure 1 As shown, a multi-body polar navigation ship disclosed by the present invention is composed of multiple hulls. The hull mainly includes an icebreaker bow structure 1, a cargo hold structure 2, a bow ballast tank 3 and a tail ballast tank 4, an engine room 5, and a tail 6 ducted propellers, 7 superstructures.

[0028] The hull is an elongated watertight cabin structure, and the hull is in a streamlined structure, symmetrically arranged left and right. The head column of the ice-breaking head structure design below the waterline is inclined, forming an angle of about 30° with t...

Abstract

The invention discloses a multi-body arctic navigation ship which comprises a plurality of ship body structures. The ship body structures comprise an ice-breaking stem structure, a cargo compartment structure, a head ballast tank, a tail ballast tank, a side ballast tank and an engine room. The upper portions of the ship body structures are provided with superstructures, and the tails of the ship body structures are provided with a plurality of propellers. The head ballast tank is communicated with the tail ballast tank and the side ballast tank through pipes; and among the head ballast tank, the tail ballast tank and the side ballast tank, the water flow direction is controlled through a solenoid valve and a ballast pump. According to the multi-body arctic navigation ship, a conventional mode of ice breaking by a single ship body is replaced with multi-ship body ice breaking, and the ice-breaking capability and flexibility during polar region ice region navigation are greatly improved; and the ship expands an ice breaking area, so that a safer navigation region is opened up. A head molded line is optimized, and main engine power needed for ice region navigation is reduced.

Description

technical field [0001] The invention belongs to the technical field of ship hull design, and in particular relates to a polar navigation ship with a multi-body structure. Background technique [0002] As the global climate warms, the Arctic ice is gradually melting, and the number of ships passing through the Arctic waters is increasing year by year. Compared with the traditional Suez Canal, the voyage of the polar waterway is greatly shortened, and its commercial value is constantly being explored by the shipping industry. The development of ships suitable for polar voyages is increasingly important. The environment in the polar seas is harsh, and the ice floating on the sea surface poses a serious threat to the safety of ships. [0003] Traditional ships in ice areas rely on high-power main engines, large thrust provided by propellers, extrusion of ice by the bow, and repeated collisions to break the ice, so as to realize the function of ice navigation. However, the ope...
