Description

Technical Field

[0001] This invention relates to the field of ship design technology, and in particular to a cabin layout structure. Background Technology

[0002] Currently, during the ship's cabin layout, after the main engine is located in the engine room, space needs to be reserved for the installation of the shaft generator. Conventionally, this reserved space requires the placement of ballast pump units, high-level seawater valve boxes, and low-level seawater valve boxes to provide ballast water for adjusting the ship's buoyancy. However, the shaft generator is prone to interference with the installation positions of these components. Furthermore, the ballast pump units, high-level seawater valve boxes, and low-level seawater valve boxes can only be installed after the main engine is installed, resulting in a lengthy installation and commissioning time. Additionally, in existing technology, when the ship is in the dockside stage of construction, seawater cooling is required for equipment commissioning. At this time, the ship is unloaded, and the high-level and low-level seawater valve boxes are still some distance from the hull baseline when placed in the engine room. In this situation, the high-level and low-level seawater valve boxes cannot contact the water surface, making it impossible to introduce seawater to meet the equipment commissioning water needs. Therefore, ballast needs to be applied to the stern of the ship, or external water supply is required to meet the equipment commissioning water needs. Summary of the Invention

[0003] The purpose of this invention is to provide a ship cabin layout structure that allows for the simultaneous installation of the ballast pump set, high-level seawater valve box, and low-level seawater valve box during the installation of the ship's main engine, avoiding interference with the shaft generator equipment, saving installation and commissioning time. Furthermore, when the ship is in the dock stage of the construction process, there is no need to ballast the stern of the ship or meet the equipment commissioning water needs through external water supply.

[0004] To achieve the above objectives, the present invention provides a ship cabin layout structure, wherein the ship cabin includes an engine room and a cargo hold, and the engine room and the cargo hold are separated by a vertically arranged first panel.

[0005] A transverse platform is provided below the end of the cargo hold near the first deck. The end of the transverse platform is connected to the first deck. Watertight bulkheads are provided on both sides of the transverse platform. The transverse platform, the first deck, the two watertight bulkheads, the forward wall of the cargo hold, and the engine room floor form a concave expansion space. An opening is provided on the first deck. The concave expansion space is connected to the engine room through the opening. A high-level seawater valve box, a low-level seawater valve box, and a ballast pump set are provided in the concave expansion space. The bottom surface of the low-level seawater valve box is flush with the hull baseline.

[0006] Furthermore, the ballast pump set includes a first seawater ballast pump body, a ballast pipeline, and a second seawater ballast pump body. One end of the ballast pipeline is connected to the high-level seawater valve box, and the other end is connected to the low-level seawater valve box. The first seawater ballast pump body is located on the ballast pipeline near the high-level seawater valve box, and the second seawater ballast pump body is located on the ballast pipeline near the low-level seawater valve box.

[0007] Furthermore, the high-level seawater valve box includes a box body, a purge pipe, and a grating device. The box body is provided with an interface for communicating with the ballast pipeline. The purge pipe and the grating device are provided inside the box body. One end of the purge pipe is fixed to the box body, and the other end is provided with a conical air inlet. The conical air inlet is located above the grating device.

[0008] Furthermore, the angle between the generatrix of the conical air inlet and the axis is greater than or equal to 60°.

[0009] Furthermore, the bottom of the box is provided with a sand-draining hole.

[0010] Furthermore, the concave extension space is provided with a pipe tunnel space, and the pipe tunnel space is also provided with a bilge water pipe and a sweeping pipe.

[0011] Furthermore, the distance from the transverse platform to the hull baseline is greater than or equal to 5800 mm.

[0012] Furthermore, the high-position seawater valve box is located near the port side within the concave expansion space and is attached to one of the watertight bulkheads, while the low-position seawater valve box is located near the starboard side within the concave expansion space and is attached to another of the watertight bulkheads.

[0013] Compared with existing technologies, the ship's cabin layout structure of this invention has the following advantages: A concave expansion space is formed by the transverse platform, the first bulkhead, the two watertight bulkheads, the forward wall of the cargo hold, and the engine room floor plate. This space is used to install the ballast pump unit, the high-level seawater valve box, and the low-level seawater valve box, thus expanding the internal space of the engine room. During the installation of the ship's main engine, the ballast pump unit, the high-level seawater valve box, and the low-level seawater valve box are installed simultaneously, avoiding interference with the installation of shaft-mounted equipment and saving installation and commissioning time. Furthermore, the bottom surface of the low-level seawater valve box is flush with the hull baseline. When the ship is in the dock stage of construction, the low-level seawater valve box can contact the water surface, meeting the equipment commissioning water needs when the ship is in an unloaded state, without the need for ballasting the stern or relying on external water supply for equipment commissioning.

[0021] like Figure 1 As shown, a preferred embodiment of the present invention discloses a ship cabin layout structure, comprising an engine room 1 and a cargo hold 2, which are separated by a vertically arranged first bulkhead 3. To facilitate the installation of the high-level seawater valve box 7, the low-level seawater valve box 8, and the ballast pump assembly 9, and to avoid interference with the installation of the shaft generator equipment, the ballast pump assembly 9, the high-level seawater valve box 7, and the low-level seawater valve box 8 are installed simultaneously during the installation of the ship's main engine. A transverse platform 4 is provided below the end of the cargo hold 2 near the first bulkhead 3, and the end of the transverse platform 4 is connected to the first bulkhead 3. Watertight bulkheads 5 are provided on both sides of the transverse platform 4. (See reference...) Figure 1 , Figure 2The transverse platform 4, the first deck 3, the two watertight bulkheads 5, the forward wall of the cargo hold 2, and the bottom plate of the engine room 1 form a concave expansion space 6. In order to connect the engine room 1 and the concave expansion space 6, an opening is provided on the first deck 3. The concave expansion space 6 is equipped with a high-level seawater valve box 7, a low-level seawater valve box 8, and a ballast pump set 9. The bottom surface of the low-level seawater valve box 8 is flush with the hull baseline 10. When the ship is in the dock stage of the construction process, the low-level seawater valve box 8 can contact the water surface to meet the equipment commissioning water needs when the ship is in an unloaded state.

[0022] Furthermore, in this embodiment, to facilitate the arrangement of the ballast pump group 9 and simplify the pipeline structure, the ballast pump group 9 includes a first seawater ballast pump body 91, a ballast pipeline 92, and a second seawater ballast pump body 93. Specifically, one end of the ballast pipeline 92 is connected to the high-level seawater valve box 7, and the other end is connected to the low-level seawater valve box 8. The first seawater ballast pump body 91 is located on the ballast pipeline 92 near the high-level seawater valve box 7, and the second seawater ballast pump body 93 is located on the ballast pipeline 92 near the low-level seawater valve box 8. The low-level seawater valve box 8 is in contact with the sea surface. Seawater is transported to the low-level seawater valve box 8 through the second seawater ballast pump body 93, and the first seawater ballast pump body 91 transports seawater to the high-level seawater valve box 7 through the ballast pipeline 92. The seawater is then transported through the pipeline system to meet the water requirements for equipment commissioning.

[0023] Furthermore, in this embodiment, to facilitate the design of the high-level seawater valve box 7 and the low-level seawater valve box 8, the high-level seawater valve box 7 and the low-level seawater valve box 8 have the same structure. In this embodiment, only the high-level seawater valve box 7 will be described. Specifically, the high-level seawater valve box 7 includes a box body 71, a purge pipe 72, and a grating device. To facilitate the connection between the box body 71 and the ballast pipe 92, please refer to... Figure 3 The housing 71 has an interface 711 for connecting to the ballast pipe 92. Inside the housing 71 are a blow-wash pipe 72 and a grating device. One end of the blow-wash pipe 72 is fixed to the housing 71 for connecting to the compressed air in the engine room 1, and the other end has a conical air inlet 721 located above the grating device. During navigation, the ship periodically blows and washes the grating device through the conical air inlet to prevent dirt from adhering to it. In this embodiment, the design of the conical air inlet 721 increases the blowing area of ​​the grating device and improves cleaning efficiency. Preferably, the angle between the generatrix of the conical air inlet 721 and the axis is greater than or equal to 60°. In this embodiment, the angle between the generatrix of the conical air inlet 721 and the axis is equal to 60°. Further, for the discharge of sand from the housing 71, refer to... Figure 3 A sand-draining hole 712 is also provided at the bottom of the box 71. Furthermore, in this embodiment, to facilitate the arrangement of the high-level seawater valve box 7 and the low-level seawater valve box 8, refer to... Figure 2The high-position seawater valve box 7 is located in the concave expansion space 6 near the port side and is attached to a watertight bulkhead 5. The low-position seawater valve box 8 is located in the concave expansion space 6 near the starboard side and is attached to another watertight bulkhead 5.

[0024] Furthermore, in this embodiment, to facilitate the arrangement of the piping system, a pipe tunnel space 61 is provided within the recessed expansion space 6. The pipe tunnel space 61 also houses the bilge water pipe and the bilge sweeping pipe. In this embodiment, to ensure that the recessed expansion space 6 is sufficient, the distance from the transverse platform 4 to the hull baseline 10 is greater than or equal to 5800mm. The distance from the transverse platform 4 to the hull baseline 10 can be adaptively adjusted according to actual installation requirements.

[0025] In summary, this embodiment of the invention provides a ship compartment layout structure that forms a recessed expansion space 6 through the transverse platform 4, the first bulkhead 3, the two watertight bulkheads 5, the forward wall of the cargo hold 2, and the bottom plate of the engine room 1. This space is used to install the ballast pump unit 9, the high-level seawater valve box 7, and the low-level seawater valve box 8, thus expanding the internal space of the engine room 1. When the main engine a is installed, the ballast pump unit 9, the high-level seawater valve box 7, and the low-level seawater valve box 8 are installed simultaneously, avoiding interference with the installation of the shaft generator b and saving installation and commissioning time. Furthermore, the bottom surface of the low-level seawater valve box 8 is flush with the hull baseline 10. When the ship is in the dock stage of construction, the low-level seawater valve box 8 can contact the water surface, meeting the equipment commissioning water needs when the ship is in an unloaded state, without the need for ballasting the stern or relying on external water supply for equipment commissioning.

[0026] The above description is only a preferred embodiment of the present invention.
