Technical Field

The invention relates to a container ship cargo hold, in particular to a container cargo hold channel structure.

Background

The cargo compartment area of a container ship is usually provided with a deep fuel tank, and a sewage well for discharging the bottom water of the cargo compartment is generally arranged in the inner bottom area of one transverse compartment wall of the cargo compartment adjacent to the deep fuel tank, so that the tail end of the cargo compartment can be approached as much as possible, and the discharge of the bottom water of the cargo compartment is convenient.

The otter board part that the bilge well has the hole that leaks can be sheltered from by the container, and the remaining structure top of bilge well is covered by the fuel tank, and there is the jam condition in the bilge well simultaneously, often causes the unable smooth emission of cargo hold bilge water, and two bilge wells of two horizontal layout can usually be in the tail end of a cargo hold, and after the crew utilized the vertical passageway of cargo hold to reach the cargo hold bottom, the otter board that can open the bilge well just can not have the container to correspond the position in the cargo hold must be guaranteed, and maintenance are comparatively inconvenient.

Furthermore, this form of construction is detrimental to the break stability of the vessel from a safety point of view. When the ballast branch pipe of the side ballast tank is connected into the ballast main pipe which is positioned in the ship and is affected by the bottom pipe, the ballast branch pipe needs to transversely penetrate through the bottom ballast tank, so that the ballast branch pipe penetrating through the side ballast tank also considers that the ballast branch pipe is damaged once the bottom ballast tank is damaged according to the SOLAS requirement, and the accumulated water inflow of the side ballast tank needs to be considered because the branch pipe is communicated with the side ballast tank, namely the bottom ballast tank and the side ballast tank simultaneously enter water, so that the damaged water inflow is increased, the ship transverse inclination angle is increased, and the adverse result is brought to the damaged stability of the ship. According to the design of the cargo hold, the fuel tank and the inner bottom area in the prior art, the ballast branch pipe cannot avoid the ballast tank at the bottom, so that hidden troubles exist.

The invention adopts the following technical scheme:

a cargo hold channel structure of a container ship is characterized in that a fuel oil hold and a cargo hold are adjacently arranged in the front-back direction, two sewage wells 7 are respectively arranged on two transverse sides in an inner bottom area of a ship body below the junction of the fuel oil hold and the cargo hold, the edge of the bottom side of the fuel oil hold is sunken inwards, an overhaul channel 8 is formed in the transverse direction of the ship body, and the overhaul channel 8 is positioned right above the sewage wells 7 on the two transverse sides of the ship body; the side ballast branch pipe 1 extends upwards from the pipe header 2 into the maintenance channel 8, is arranged along the maintenance channel 8 and finally accesses the side ballast tank.

Preferably, the access channel 8 has at its bottom a cover plate 6 that can be opened and communicates with the sump well 7.

Preferably, a mesh plate 2 is arranged above the sewage well 7 and corresponding to the cargo hold.

Preferably, a submersible pump for discharging sewage is arranged in the sewage well 7.

Preferably, the main body of the service passage 8 is in a rectangular body structure.

Further, the side ballast branch pipe 1 is arranged at a lower bottom corner of the rectangular structure on the side close to the fuel tank.

The invention has the beneficial effects that:

1) the transverse channel which can enable a crew to inspect and maintain the sewage well on site is arranged in the ship cabin, the water at the bottom of the cargo hold can be smoothly discharged, and the timely overhaul and cleaning of the sewage well are ensured.

2) Even if a container is arranged above the sewage well in the cargo hold, the overhaul work is not influenced.

3) The space of the channel is ingeniously utilized to provide a layout place of the side ballast branch pipe, the adverse factor of damage stability is eliminated, and the damage stability and the ship safety are improved. And also prevents the piping from being corroded.

Detailed Description

The invention is further described with reference to the following figures and specific examples.

Example one (comparative example):

the transverse bulkhead of the existing container fuel tank adjacent to the cargo hold extends upwards from the inner bottom to the main deck, and a part of the bilge well is positioned in the cargo hold, and a part of the bilge well is positioned below the fuel tank and covered by the fuel tank. If the cargo hold is loaded with containers, the container will cover the bilge well in the cargo hold area. As shown in fig. 1 and 2.

Since the ballast branch lines of the side ballast tanks need to be routed laterally through the bottom ballast tanks when accessing the ballast main lines located in the bottom pipe in the ship, as shown in fig. 3.

The conventional arrangement does not provide the crew with this passage, the part of the bilge well that has the water leakage holes can be covered by the container, while the rest of the structure of the bilge well is covered by the fuel tank. Two bilge wells are usually transversely arranged at the tail end of a cargo hold, and after a crew member reaches the bottom of the cargo hold by using a vertical channel of the cargo hold, a transverse channel is lacked for the crew member to walk left and right along the width direction of the ship. From the angle of use, there is technical defect in current access structure, has brought very big inconvenience for crewman's work.

Meanwhile, the structural form is not beneficial to the damage stability of the ship from the safety point of view. When the ballast branch pipe of the side ballast tank is connected to the ballast main pipe which is positioned in the ship and is affected by the bottom pipe, the ballast branch pipe which passes through the tank needs to transversely pass through the bottom ballast tank, so that once the bottom ballast tank is damaged according to the SOLAS requirement, the ballast branch pipe which passes through the tank is also considered to be damaged, and the branch pipe is communicated to the side ballast tank, so that accumulated water inflow of the tank is caused, namely the bottom ballast tank and the side ballast tank simultaneously enter water, the damaged water inflow is increased, the ship transverse inclination angle is increased, and the damage stability of the ship is brought with a negative result.

Example two:

referring to fig. 4-6, a fuel tank and a cargo hold are adjacently arranged in the front-rear direction of the cargo hold, two sewage wells 7 are respectively arranged on two transverse sides in an inner bottom area of a ship body below the junction of the fuel tank and the cargo hold, the edge part of the bottom side of the fuel tank is sunken inwards, an overhaul channel 8 is formed along the transverse direction of the ship body, and the overhaul channel 8 is positioned right above the sewage wells 7 on two transverse sides of the ship body; the side ballast branch pipe 1 extends upwards from the pipe header 2 into the maintenance channel 8, is arranged along the maintenance channel 8 and finally accesses the side ballast tank.

The width, the depth and the height of the access passage can be adjusted according to actual arrangement and rule requirements, and the trend and the number of the side ballast branch pipes can be adjusted according to actual cabin division.

Referring to fig. 5, the access channel 8 has at its bottom a cover plate 6 that can be opened and communicates with the sump 7.

Referring to fig. 5, a mesh plate 2 is arranged above the bilge well 7 corresponding to the cargo compartment.

Referring to fig. 5, a submersible pump for discharging sewage is provided in the sewage well 7.

As can be seen in fig. 4-5, the main body of the service access 8 is a rectangular structure.

Referring to fig. 5, the side ballast branch pipes 1 are arranged at the lower bottom corner of the rectangular body structure on the side close to the fuel tank.

In particular, the present embodiment provides a structure of a passage for a cargo hold of a container ship, which can facilitate passage of crew members and also provide a place for arranging side ballast branch pipes.

A transversely through maintenance channel is arranged on the sewage well, and the movable cover plate part of the sewage well is exposed, so that a crew can transversely walk through the sewage well.

Referring to fig. 6, the ballast branch lines of the side ballast tanks are routed directly into the service aisle, to the midship, and then piped into the ballast main lines. Ensuring that the section of tube is higher than the inner bottom. See figures 4-6 for details.

This embodiment has realized the maintenance access structure of container ship cargo hold bilge well, has guaranteed the timely maintenance clearance of bilge well, and the adjustment of topside ballast branch pipe arrangement position both had do benefit to the damage stationarity, has also avoided the corruption of piping.

While the preferred embodiments of the present invention have been described, those skilled in the art will appreciate that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
