Problems solved by technology

[0009] In order to overcome the above-mentioned shortcomings, the present invention provides a stable and balanced ship type, which effectively solves the problem of "V"-shaped cross-section ships with high center of gravity, small freeboard, high rolling frequency, large influence of free liquid surface, and relatively low water inlet angle. the problem of instability

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, preferred scheme of the present invention is described in detail:

[0027] Figure 1 to Figure 5 is a cross-sectional view of a preferred embodiment of the present invention, relative to Figure 5 The improvements are as follows:

[0028] A stable and balanced ship type is composed of a shell 1 and a deck, and a balance cabin 5 is arranged on the bottom or / and side of the inside and / or outside of the shell 1. This cabin can also be arranged on the bottom and the side to reduce the center of gravity of the ship.

[0029] The balance cabin 5 is used separately or in combination with the cabin above it. Different from the method of increasing the weight of the ship or adjusting the arrangement in the prior art to increase the center of gravity of the ship, the shape of the cross section of the ship is changed, thereby effectively reducing the height of the center of gravity of the ship.

[0030] A double bottom 4 and / or a ...

Abstract

The invention relates to a stable and balanced ship type. The stable and balanced ship type consists of a housing and a deck, wherein balanced cabins are arranged on the bottom or / and the side surface of the inner part and / or the outer part of the housing, and each of the balanced cabins and a corresponding cabin above the corresponding balanced cabin are used in a separating manner or in a combined manner; double-layer bottoms are arranged under the balanced cabins and / or bottom edge cabins are arranged on the side surfaces of the balanced cabins; top edge cabins are arranged on the bottom edge cabins; and the shape of the double-layer bottoms and / or the bottom edge cabins and / or the top edge cabins and / or the balanced cabins is flat or / and an angle or / and an arc folding shape. According to the stable and balanced ship type disclosed by the invention, the height of barycentre of a ship is reduced, freeboard is increased, a down flooding angle is increased, roll frequency is reduced, and influence on free fluid surface is reduced, so that the ship tends to a stable and balanced condition, and the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of stability design of military and civilian ships or marine engineering structures. Background technique [0002] At present, the midship area of ​​the latest ship type uses an approximate "V"-shaped cross section (such as figure 1 ), although there are many advantages of improvement to the rectangular cross-section currently used, there are also the following disadvantages compared with the ship type with the same load capacity or cross-sectional area: [0003] 1. Relatively higher center of gravity; [0004] 2. The freeboard of the ship is reduced; [0005] 3. The frequency of ship rolling increases relatively; [0006] 4. The influence of free liquid surface increases; [0007] 5. The height of the water inlet angle is relatively lower; [0008] From the above shortcomings, it can be deduced that there is a hidden danger of unstable balance in the static stability of the ship.
