In order to secure the structural strength of the ship lateral structure, a large number of side frames 2 are generally provided on the ship side of the ship tank 100, and a large number of bottom ribs 3 are provided on the bottom of the ship tank 100. However, when different cargoes are loaded, the required structural strength is different, and the universality of the bulk carrier for loading cargoes is poor. In order to solve the problems existing in the background art and improve the market competitiveness of the ship, the embodiment provides a bulk cargo ship which comprises a cabin reinforcing mechanism, each typical loading condition of the bulk cargo ship is analyzed, and the cabin reinforcing mechanism is individually designed to meet the structural strength of each 100-region cabin.

Generally, a bulk carrier has a plurality of cabins 100 along the length of the carrier, and various loading conditions exist during loading, such as: each of the hold 100 is filled with cargo, and each of the hold 100 is uniformly loaded with light cargo or with compartments, wherein a portion of the hold 100 is loaded with heavy cargo; to meet the requirements of different loading conditions, a corresponding cabin strengthening mechanism may be provided for each cabin 100.

In order to meet the above personalized requirements, the embodiment provides a cabin strengthening mechanism, which includes a chute assembly, a plurality of groups of strengthening assemblies, and a first driving assembly. As shown in fig. 1-3, the ramp assembly is extended and arranged in the length direction of the ship; the reinforcing assemblies comprise a side frame 2 arranged on the side surface of a ship board of the cabin 100 and a bottom ribbed plate 3 arranged at the bottom of the cabin 100, the side frame 2 and the side frame 2 are arranged oppositely, and a plurality of groups of reinforcing assemblies can be fixed on the slideway assemblies in parallel at intervals; the first driving assembly is used for driving the reinforcing assembly to slide on the slideway assembly.

In order to meet different loading conditions, the bearing strength required by each cabin 100 is calculated, a plurality of groups of reinforcing assemblies are driven to move on the slideway assembly through the first driving assembly, and the arrangement of the plurality of groups of reinforcing assemblies is changed to increase the strength of the corresponding cabin 100; when uniform light goods are loaded, a plurality of groups of reinforcing components are uniformly arranged on the cabin 100 at intervals so as to ensure that the stress of the cabin 100 is uniform; when heavy cargo is loaded, multiple sets of reinforcement assemblies can be targeted to the loading area of the heavy cargo hold 100 to increase the strength of this section. In consideration of the continuity of the load transmission, the coordinates of a side frame 2 and a bottom rib 3 along the ship length are required to be coincident, and a group of reinforcing members, that is, the side frame 2 and the bottom rib 3, can slide simultaneously.

Specifically, the broadside frame 2 and the bottom rib plate 3 are respectively provided with a mounting hole, the clamping plate 4 is provided with a plug buckle, and the mounting holes are plugged in the plug buckle; when the broadside frame 2 and the bottom ribbed slab 3 are fixed, the second driving component drives the broadside frame 2 and the bottom ribbed slab 3 to move longitudinally relative to the clamping plate 4 until the mounting holes correspond to the inserting buckles, and then the second driving component drives the broadside frame 2 and the bottom ribbed slab 3 to move relative to the inserting buckles so that the broadside frame 2 and the bottom ribbed slab 3 are respectively inserted into the inserting buckles; when the broadside frame 2 and the bottom rib plate 3 slide, the second driving assembly drives the broadside frame 2 and the bottom rib plate 3 to move towards the opposite direction of the inserting buckle, so that the broadside frame 2 and the bottom rib plate 3 are separated from the inserting buckle respectively, then the second driving assembly drives the broadside frame 2 and the bottom rib plate 3 to move longitudinally relative to the card board 4, the broadside frame 2 and the bottom rib plate 3 move to a state that the broadside frame 2 and the bottom rib plate 3 are not interfered with the card board 4, and the broadside frame 2 and the bottom rib plate 3 can move on the slide rail 1.

When the hold 100 is loaded with dangerous cargo such as a tanker, the corresponding hold 100 where the side frames 2 and the bottom ribs 3 are located is a dangerous area. In consideration of power safety and stability, when the second driving assembly adopts the electric driving device, the electric driving device has higher explosion-proof requirement, so that the production cost is increased; in this embodiment, the second driving assembly is hydraulically driven, and after the side frame 2 and the bottom rib plate 3 are moved in place, the reinforcing assembly is fixed by using hydraulic driving to prevent the position thereof from changing. Likewise, optionally, the first drive assembly is hydraulically driven.
