Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, a bulk carrier of the present embodiment has a transverse bulkhead 100 for a ship that divides a hull transversely into a plurality of compartments. The transverse bulkhead 100 of the ship comprises a first layer plate 110 and a second layer plate 120, the first layer plate 110 and the second layer plate 120 are arranged at intervals and form a cavity 130, the tops of the first layer plate 110 and the second layer plate 120 are used for being connected with a deck 300 and/or a top side cabin 400 of the ship, and the first layer plate 110 and the second layer plate 120 are connected with the hull of the ship in a sealing mode in the circumferential direction.
In this embodiment, the transverse bulkhead 100 of the ship adopts a double-layer structure design, and the cavity 130 formed between the first layer plate 110 and the second layer plate 120 can be used as a watertight cabin to act as a pressure tank for use, so that the overall strength of the bulkhead is increased, the distance between the two bulkheads can be increased, a stool is not only avoided, the utilization rate of the space in the cabin is increased, the transportation capacity of the bulk carrier is further increased, and the manufacturing cost of the ship body can be reduced.
As shown in fig. 2, in the present embodiment, the first and second laminates 110 and 120 are provided with reinforcements on the sidewalls thereof. The structural strength of the transverse bulkhead 100 of the ship is further enhanced by providing the reinforcing parts on the sidewalls of the first or second deck 110 or 120, thereby preventing deformation or damage due to a large load.
In other embodiments, reinforcements may be provided only on the first ply 110 or the second ply 120.
As shown in fig. 2, in the present embodiment, the reinforcement is provided on the side walls of the first and second laminates 110 and 120 located within the cavity 130. The presence of the reinforcement on one side inside the cavity 130 on the one hand avoids the occupation of the compartment between the two transverse bulkheads 100 of the ship and on the other hand makes it possible to make the compartment look aesthetically pleasing, while reducing the difficulty of cleaning the compartment.
Of course, in other embodiments, the reinforcement portion may be disposed on the sidewall outside the cavity 130, and is not limited herein.
In this embodiment, the stiffeners include stiffeners, vertical girders 101, and horizontal girders 102. Of course, the type and number of the reinforcing parts can be selected according to the magnitude of the load to be borne by the bulkhead, and the bulkhead can have enough strength.
In this embodiment, the first ply 110 and the second ply 120 are spaced 120cm apart. By setting the interval between the first laminate 110 and the second laminate 120 to the above-mentioned distance, it is possible to satisfy the supporting strength on the one hand and to use the space between the two laminates for other purposes on the other hand.
Of course, the distance between the first ply 110 and the second ply 120 can be other lengths, but is preferably between 80-120 cm.
As shown in fig. 1 and 2, in the present embodiment, the bulk carrier includes stools 200, and the lower ends of the first and second floors 110 and 120 of part of the transverse bulkhead 100 of the ship are connected to the stools 200. Through setting up end bench 200, the joint strength of reinforcing bulkhead and boats and ships bottom avoids bulkhead and boats and ships bottom lug connection to cause the damage to boats and ships bottom.
As shown in fig. 2, in the present embodiment, the bottom stool 200 has an upper surface 210, and the first and second floors 110 and 120 are connected to the upper surface 210. By connecting the first laminate 110 and the second laminate 120 to the upper end surface 210, welding is facilitated, and the connection strength is enhanced.
In this embodiment, the bottom stool 200 has a hollow structure, and the width of the bottom stool 200 is gradually widened from top to bottom. The bottom stool 200 with the structure improves the supporting strength and reduces the overall weight of the ship, and is used as a ballast water tank to enhance the ballast water amount of the ship.
As shown in fig. 1, the bulk carrier further includes a bottom side tank 500, and the lower ends of the first and second floors 110 and 120 of the partial transverse bulkhead 100 of the ship are connected to the bulkhead of the bottom side tank 500.
The transverse bulkhead 100 of the ship is connected to a ship body through the first laminate 110 and the second laminate 120 in a sealing way, and vertical stiffening materials, vertical girders 101 and horizontal girders 102 are arranged on the side wall in the cavity 130, so that the original channel-shaped bulkhead is replaced, the structural strength of the bulkhead is ensured, and a top stool can be eliminated.
In order to ensure the structural strength of the transverse bulkhead 100 of the ship, the vertical stiffening materials, the vertical girders 101 and the horizontal girders 102 need to be arranged reasonably. The vertical girders 101 can be arranged according to the positions of the partition boards of the bottom stools 200, the vertical reinforcing materials on the first layer board 110 and the second layer board 120 correspond to the aggregates of the bottom stools 200, and the positions of the horizontal girders 102 can be arranged according to the calculation results of the actual ship-shaped strength.
The cavity 130 between the first layer plate 110 and the second layer plate 120 can be internally provided with a ladder way, a sounding pipe and the like, so that the damage of goods to the ladder way pipe system is avoided. The transverse bulkhead 100 of the ship can be flexibly configured according to the loading characteristics of different ships, the ballast water amount in the middle of the cargo hold of the bulk cargo ship is increased, the still water bending moment of the middle arch of the hull beam under the ballast working condition is effectively reduced, the purpose of reducing the structural weight of the cargo hold area is achieved, meanwhile, the deformation of the hull beam can be effectively controlled, and the safety of ship navigation is facilitated.
