Embodiment 1

[0048] Such as figure 1 image 3 As shown, a thousand-ton bulk carrier ship type includes a hull bow 1, a hull middle 2, and a hull stern 3. It is characterized in that the hull bow 1 is a vertical bow, and its cross section is a floating side structure, and It is a middle U shape;

[0049] The middle part of the hull 2 ​​is a parallel middle body, which is smoothly connected with the bow 1 of the hull;

[0050] The stern part 3 of the hull is a square stern, and the square stern includes a flow-out section 31 and a tail transition section 32, and the flow-out section 31, the tail transition section 32, and the parallel midbody are smoothly connected.

[0051] The outflow section 31 includes the bottom plate 311 of the outflow section, the side shell plate 312 of the outflow section and the stern seal plate 313; the bottom plate 311 of the outflow section is a horizontal plate; the side shell plate 312 uses a round bilge to connect the outflow Section ship bottom plate 311, t...

Embodiment 2

[0073] This embodiment provides a 70.5 meters, 2000-ton bulk carrier that adopts double straight-wing propeller 4, and the owner's scale is:

[0074] Total length L=70.5 meters; molded width B=13.9 meters; molded depth D=4.5 meters; draft T=3.30 meters;

[0075] Medium section coefficient Cm=0.992; L / B=5.072; B / T=4.212.

[0076] Such as figure 1 As shown, the longitudinal section lines of the hull bow 1, hull middle 2, and hull stern 3 are all smoothly connected.

[0077] At the center longitudinal section, the bow stern and the bottom plate adopt a circular arc transition with a radius of 1500 mm, and the bottom plate at the parallel center body gradually rises, and the transition section 32 of the stern adopts an inverse curve transition, and at the bottom plate 311 of the outflow section, Tend to level, in this horizontal section, straight wing propeller 4 is installed.

[0078] In this embodiment, the slope of the longitudinal section line of the bottom plate 311 of the...

Abstract

A ship line of a kilo-tonnage bulk carrier comprises a bulk carrier hull, wherein the bulk carrier hull comprises a hull front part (1), a hull middle part (2) and a hull rear part (3); the hull frontpart (1) is a vertical bow of which the cross-section is of flaring side structure and of a medium U-shape; the hull middle part (2) is a parallel middle body which is smoothly connected with the hull front part (1); the hull rear part (3) is a square stern which comprises an outflow section (31) and a stern transition section (32); and the outflow section (31), the stern transition section (32)and the parallel middle body are smoothly connected. The technical scheme provided by the invention enables the kilo-tonnage bulk carrier to have a lower resistance under the condition of same tonnageand load capacity, so as to increase the speed of the bulk carrier and improve the economical efficiency of the bulk carrier.

Description

technical field [0001] The invention relates to the field of ship lines, in particular to a thousand-ton bulk carrier ship shape. Background technique [0002] For thousand-ton inland water transport bulk carriers, the line shape of the ship is often limited by the depth of the inland water and the narrowness of the inland waterway. In order to ensure that the ship will not be stranded and the ship can turn smoothly, the bulk carrier is generally a shallow draft ship with a small length , in order to ensure the economy of the ship, under the condition of shallow draft and small ship length, the method of increasing the molded width is adopted to increase the displacement, thereby increasing the load capacity of the ship. The following problem is that while increasing the molded width, the resistance of the ship increases, and under the same load and power, the speed of the ship decreases and the economy of the ship decreases. Contents of the invention [0003] The inventi...
