Description

Technical Field

[0001] The present invention relates to the technical field of container ships, and particularly to a bow structure of a container ship. Background Art

[0002] At present, due to limitations of various factors, large container ships cannot be further increased in size at the current stage; at the same time, the use of alternative fuels will result in a loss of container positions in the cargo hold. In the conventional layout of large container ships, most of the space on the ship has been occupied by containers, and the only area that can further provide container loading is the space above the bow mooring area. However, in the prior art, the container loading space and the personnel operation space above the bow mooring area are not separated, resulting in potential safety hazards during operation. Summary of the Invention

[0003] The purpose of the present invention is to provide a bow structure of a container ship to solve the problem in the prior art that the container loading space and the personnel operation space above the bow mooring area are not separated, resulting in potential safety hazards during operation.

[0004] To solve the above problems, the present invention provides a bow structure of a container ship. The bow structure of the container ship includes: a load-carrying deck located at the bow of the container ship, and a load-carrying structure is provided on the load-carrying deck, and the load-carrying structure can place newly added containers; a mooring deck provided at the bow of the container ship and located below the load-carrying deck, the mooring deck is connected to the load-carrying deck, and the mooring deck can allow operators to perform mooring operations on the container ship; a windshield structure provided above the load-carrying deck, the windshield structure surrounds the outside of the newly added containers and can protect the newly added containers.

[0005] As an alternative technical solution of the bow structure of the container ship, the bow structure of the container ship further includes a support structure, one end of the support structure is connected to the load-carrying deck, and the other end of the support structure is connected to the mooring deck.

Both the first load-bearing area and the second load-bearing area can accommodate newly added containers.

[0008] As an alternative technical solution for the bow structure of a container ship, in the length direction of the container ship, the length of the first load-bearing area is greater than the length of the second load-bearing area.

[0009] As an alternative technical solution for the bow structure of a container ship, the load-bearing structure includes a first truss-type load-bearing member. The truss-type load-bearing member includes a first transverse support member, a first vertical support member, and a first connecting member. One end of the first vertical support member is connected to the load-bearing deck, the other end of the first transverse support member is connected to the first vertical support member, and the first connecting member connects the first transverse support member and the first vertical support member.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be construed as a limitation of the present invention.

[0031] Such as Figures 1 to 3As shown in the figure, this embodiment provides a bow structure of a container ship. The bow structure of the container ship includes a load deck 1, a mooring deck 2, and a windshield structure 3. Among them, the load deck 1 is located at the bow of the container ship 6, and a load structure 11 is provided on the load deck 1. The load structure 11 can place the newly added container 5; the mooring deck 2 is arranged at the bow of the container ship 6 and is located below the load deck 1. The mooring deck 2 is connected to the load deck 1, and the mooring deck 2 can allow operators to perform mooring operations on the container ship 6; the windshield structure 3 is arranged above the load deck 1. The windshield structure 3 surrounds the outside of the newly added container 5 and can protect the newly added container 5.

[0032] By adopting the bow structure of the container ship of the present invention, the mooring deck 2 is arranged at the bow of the container ship 6 and is located below the load deck 1. Such an arrangement can separate the load deck 1 and the mooring deck 2. In this way, when the operator performs mooring operations on the mooring deck 2, there is no risk of the newly added container 5 falling, thus meeting the requirement of loading additional containers on the ship while ensuring the safe operation space for the operator; at the same time, connecting the mooring deck 2 and the load deck 1 can ensure that the bow structure of the container ship has sufficient strength and stiffness to meet the design requirements; and arranging the windshield structure 3 above the load deck 1 can not only prevent sea waves from rushing onto the load deck and protect the newly added container 5, but also reduce the wind resistance during the operation of the container ship. By using the bow structure of the container ship of the present invention, the problem that the container loading space and the personnel operation space above the bow mooring area in the prior art are not separated, resulting in potential safety hazards during operation, is effectively solved.

[0033] In some embodiments, in order to further improve the connection strength between the mooring deck 2 and the load deck 1, the bow structure of the container ship further includes a support structure 4. One end of the support structure 4 is connected to the load deck 1, and the other end of the support structure 4 is connected to the mooring deck 2. Such an arrangement can enhance the connection strength between the mooring deck 2 and the load deck 1 to meet the design requirements.

[0034] Specifically, as Figure 3 shown, the support structure 4 includes a plurality of support columns 41 arranged at intervals. Among them, one end of the support column 41 is connected to the bottom of the load deck 1, and the other end of the support column 41 is connected to the mooring deck 2. Such an arrangement can, while meeting the support strength, make the size of the support column 41 smaller and the number fewer, and the support column 41 will not block the line of sight of the operator on the mooring deck 2.

[0035] As Figure 1 and Figure 2As shown, the container ship 6 has a symmetry line 61, which divides the container ship 6 into two symmetrical parts. Among them, the load-bearing structure 11 has a first load-bearing area 111 and a second load-bearing area 112. The first load-bearing area 111 is symmetrically distributed along the symmetry line 61. At the same time, the second load-bearing area 112 is symmetrically distributed along the symmetry line 61 and is located on both sides of the first load-bearing area 111. Both the first load-bearing area 111 and the second load-bearing area 112 can place the newly added containers 5, so that the number of newly added containers 5 placed can be increased to a large extent.

[0036] Furthermore, in the front-rear direction of the container ship 6, the length of the first load-bearing area 111 is set to be greater than the length of the second load-bearing area 112. Due to the shielding of the windshield structure 3, in order to avoid interference during the hoisting of the containers and increase the container positions as much as possible, the newly added containers at the bow should be arranged as close to the stern as possible.

[0037] Specifically, the load-bearing structure 11 includes a first truss-type load-bearing member. Such a setting can enhance the structural strength of the load-bearing structure 11 without adding additional reinforcement members. In an embodiment not shown in the figure, the truss-type load-bearing member includes a first transverse support member, a first vertical support member, and a first connecting member. Among them, one end of the first vertical support member is connected to the load-bearing deck 1, the first transverse support member is connected to the other end of the first vertical support member, the first connecting member connects the first transverse support member and the first vertical support member, and the first transverse support member, the first vertical support member, and the first connecting member enclose the first load-bearing area 111. Through the first load-bearing area 111, the newly added containers 5 can be placed better.

[0038] Similarly, the load-bearing structure 11 further includes a second truss-type load-bearing member. Among them, the second truss-type load-bearing member includes a second transverse support member, a second vertical support member, and a second connecting member. One end of the second vertical support member is connected to the load-bearing deck 1, the second transverse support member is connected to the other end of the second vertical support member, the second connecting member connects the second transverse support member and the second vertical support member, and the second transverse support member, the second vertical support member, and the second connecting member enclose the second load-bearing area 112. With such a setting, the newly added containers 5 can also be placed better through the second load-bearing area 112.

[0039] In some embodiments, the windshield structure 3 includes a windward surface 31 and two side surfaces 32 connected to both sides of the windward surface 31. Among them, the two side surfaces 32 and the windward surface 31 are both connected to the load-bearing deck 1. The windward surface 31 extends from the bow of the container ship 6 upward and is inclined toward the newly added containers 5. In this way, compared with an upright windshield, it has a better drag reduction effect; at the same time, the height of the side surface 32 gradually increases in the front-rear direction of the container ship 6. This can effectively protect the sides of the newly added containers 5.

[0040] Optionally, the bow structure of the container ship further includes a foremast structure 7 provided on the load-carrying deck 1, and the foremast structure 7 is located in front of the newly added container 5.

[0041] It should be noted that the outer shape of the windshield structure 3 is determined through CFD (Computational Fluid Dynamics) verification, and at the same time, interference with the foremast structure 7 is avoided.

[0042] Specifically, the mooring deck 2 includes a deck main body 21 and mooring equipment 22, an anchor viewing platform 23, and an anchor chain compartment 24 provided on the deck main body 21. Among them, the mooring equipment 22 is provided to enable the operator to moor the container ship 6; the anchor viewing platform 23 is provided to enable the operator to observe the dropping and lifting of the anchor; the anchor chain compartment 24 is provided to stack the anchor chain.

[0043] Optionally, the mooring equipment 22 includes an anchor winch 221 and a mooring winch 222.

[0044] Furthermore, the mooring deck 2 further includes a mooring area operation platform 25 provided on the deck main body 21. The mooring area operation platform 25 can be used for the operator to perform safe operations.

[0045] Among them, in the implementation process of the technical solution of the present invention, the height position of the mooring deck 2, the position of the mooring equipment 22, the outer shape of the windshield structure 3, the position of the support column 41, etc. can be flexibly set according to the ship design and use requirements.

[0046] The advantages of the present invention are as follows;

[0047] 1. The technical solution of the present invention can provide additional container arrangement space for large container ships and improve the single-ship operation income of container ships.

[0048] 2. The technical solution of the present invention can make the container loading space relatively independent of the mooring area, ensure the safety of personnel in the mooring area, and avoid the risk of bearing the fall of containers.

[0049] 3. In the technical solution of the present invention, the load-bearing structure has good load-bearing capacity for adding containers. Only a few support columns need to be provided between the load-carrying deck and the mooring deck to ensure that the strength of the main hull meets the design requirements. Therefore, the line of sight of personnel in the mooring area is wide, which is convenient for operating and managing the mooring equipment. At the same time, the enclosed load-carrying deck can provide an excellent working environment for personnel to be protected from wind and rain.

[0050] 4. In the technical solution of the present invention, the windshield structure at the bow can prevent the deck from being washed by waves while effectively reducing wind resistance, reducing energy consumption during ship operation, reducing greenhouse gas emissions, and improving operation income.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
