Problems solved by technology

[0003] The object of the present invention is to provide a tumbler ship type aiming at the deficiencies in the prior art, which can effectively solve the problem of high center of gravity, small freeboard, high rolling frequency, large influence of free liquid surface, and high water inlet angle of ships with "V" cross section. Relatively low, poor stability and security issues

Embodiment 1

[0027] Such as figure 2 As shown, the tumbler ship type of the present embodiment includes a trapezoidal hull made of an outer shell 1 and a deck 2, the bottom of the hull is provided with a ballast tank 3, and the lower part of the outer shell 1 is provided with a hopper tank 4, A topside tank 5 is provided on the upper part of the shell 1 .

[0028] The tumbler ship type of this embodiment has increased the bottom ballast tank 3, effectively reduced the height of the center of gravity of the ship; due to the increase of the displacement volume of the ship, the freeboard is increased, and the height of the water inlet angle is relatively increased; the free liquid surface is at 5%. The area moment at the ten points is relatively reduced, so the influence of the free liquid surface is reduced; thus the ship tends to be more stable and balanced, and the safety performance is greatly improved.

[0029] The tumbler ship type of this embodiment is especially suitable for the tra...

Embodiment 2

[0032] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that: the ballast tank 3 is arranged on the outside of the bottom of the hull, the hopper tank 4 is arranged on the outside of the lower part of the shell 1, and the topside tank 5 is arranged on the outside of the shell 1 outside of the upper part. The ballast tank 3, the hopper tank 4 and the topside tank 5 are all arranged on the outside of the hull. On the one hand, it is beneficial to protect the hull shell 1 from collision damage. Transportation of goods. The ballast tank 3, the hopper tank 4 and the topside tank 5 are all arranged outside the hull, which helps to protect the hull shell 1 from collision damage on the one hand, and does not occupy the interior space of the cabin on the other hand.

[0033] As preferably, the ballast tank 3, the hopper tank 4 and the topside tank 5 are all hemmed, and the hemmed ballast tank 3, the hopper tank 4 and the topside tank 5 are conduci...

Embodiment 3

[0035] Such as Figure 4 As shown, the tumbler ship type of this embodiment also includes a balance cabin 6, which is arranged at the bottom of the hull, and the balance cabin 6 can be used separately or in combination with the hull cabin, which not only can increase the cabin volume of the hull, but also The center of gravity of the hull is effectively reduced, the displacement volume of the hull is increased, the freeboard is increased, and the angle of water entry is relatively increased, which greatly improves the stability and safety performance of the hull.

[0036] Wherein, the ballast tank 3, the hopper tank 4 and the topside tank 5 are straight-sided, the ballast tank 3 is arranged at the bottom of the balance tank 6, the two sides of the balance tank 6 and the shell 1 The lower part is provided with hopper tanks 4, which helps to protect the hull shell 1 from collision damage, and the top of the shell 1 is provided with topside tanks 5, which reduces the weight of th...

Abstract

The invention relates to the technical field of ship design, in particular to a tumbler ship model. A bottom balance cabin is additionally arranged, so that the height of the gravity center of a ship is effectively reduced; due to the fact that the volume of displacement of the ship is increased, freeboards are heightened, and the water inflow angle is relatively increased; folded edges are arranged on the double-layer bottom and the bottom edge, resistance is increased in the rolling process of the ship, and the rolling frequency is reduced; the area moment in the position of the fifty percent of the liquid level is relatively reduced, so that free liquid level influences are reduced. Thus, the ship is in a stable and balanced state, the safety performance is greatly improved, through a stability calculation method, the ship stability and balance reliability can be improved by increasing a GM value, and the safety performance is higher.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a tumbler ship type. Background technique [0002] At present, the cross-section of most ships is approximately "V" shape. The specific structure shows that the bottom is relatively sharp and thin and the side is obviously flared, so that the wet surface area of ​​the ship is small, which can effectively reduce frictional resistance and facilitate water flow to the bottom of the ship. flow, and can avoid eddy currents in the bilge, etc. However, the above-mentioned structure also leads to a relatively high center of gravity of the ship, a decrease in stability, a limited displacement volume of the ship, a decrease in the freeboard of the ship, a relative increase in the frequency caused by the small resistance during the ship rolling process, and an increase in the influence of the free liquid surface , the relatively lower height of the water inlet angle, etc., make the sta...
