Description

Cabin bottom structure, cabin and ship

Technical Field

The invention relates to the technical field of ship construction, in particular to a cabin bottom structure, a cabin and a ship.

Background

In the case of chemical-transporting vessels, since the vessel is loaded with dangerous chemicals, the residual oil (the residual chemical content in the vessel) is required to be no more than 75L at the time of unloading.

For the ship with the groove-shaped wall structure, the prior scheme is to reasonably arrange the suction port of the cargo oil pump and add a large number of anti-accumulation plates in front of the groove-shaped wall so as to prevent the cargo oil from being accumulated at the position where the cargo oil pump cannot suck, thereby meeting the requirement of residual oil quantity when unloading.

The scheme for reducing the residual oil has the defects that firstly, the oil accumulation well needs to be arranged at the left side and the rear side of the cabin as much as possible, and the arrangement difficulty is extremely high. Secondly, the effect of eliminating residual oil in the prior art is not superior, a large number of anti-accumulation plates are required to be added in front of the groove type wall to barely meet the residual oil requirement during unloading, and the cost is extremely high and the technical risk is high. Third, adding a large number of anti-accumulation plates reduces the hold capacity of the cargo hold. Fourth, the addition of the anti-accumulation plate can lead to an increase in the concentration degree of structural stress, the groove-shaped bulkhead cannot be uniformly stressed, fatigue problems can occur, and structural cracks can be even caused after long-term operation and use of the ship. Fifth, the prior art solutions require extremely high suction capacity of the cargo pump and therefore high costs for the suction of residual oil.

Accordingly, there is a need for a cabin bottom structure, a cabin and a ship that solve the above problems.

Referring to fig. 1 to 4, the present embodiment provides a cabin bottom structure including, in particular, a first cabin floor 100, a second cabin floor 200, and an oil suction well 300. The first bilge plate 100 is provided with a groove, the second bilge plate 200 is mounted on the groove and connected with the first bilge plate 100, the second bilge plate 200 is lower than the first bilge plate 100, the oil suction well 300 is provided on the second bilge plate 200, a part of the second bilge plate 200 is inclined towards the oil suction well 300, and the oil suction well 300 is configured to erect the cargo oil pump 30. That is, the first bilge plate 100 and the second bilge plate 200 are capable of forming a drain for the residual oil, so that the residual oil flows to the suction well 300 by gravity. The residual oil is gathered during unloading, so that the suction is convenient, the residual oil removal efficiency is improved, and the problem of uneven stress of the groove-shaped bulkhead caused by the addition of the anti-accumulation plate is avoided.

Specifically, the first bilge plate 100 includes a first tilting bottom 110 and a first flat bilge 120 connected side by side in the width direction of the ship, wherein the first tilting bottom 110 is located at the left side of the first flat bilge 120. The first flat bilge 120 has a lower height than the first tilting bottom 110, the first tilting bottom 110 is tilted towards the first flat bilge 120, i.e. the right side edge of the first tilting bottom 110 has a lower height than the left side edge of the first tilting bottom 110, and the right side edge of the first tilting bottom 110 is joined to the left side edge of the first flat bilge 120. The groove is formed in the first flat bilge 120, two adjacent sides of the second bilge plate 200 are respectively connected to the first flat bilge 120 and the first inclined bottom 110, that is, the length of the first flat bilge 120 is smaller than that of the first inclined bottom 110, the head of the first flat bilge 120 is flush with the head of the first inclined bottom 110, the groove is formed in the tail of the first flat bilge 120 and the tail of the first inclined bottom 110, and the sum of the lengths of the second bilge plate 200 and the first flat bilge 120 is equal to that of the first inclined bottom 110.

Preferably, the angle between the first tilting floor 110 and the plane of the first flat bilge 120 is 2 °. The above arrangement can provide a drainage effect for residual oil remaining on the first bilge plate 100. Specifically, during unloading, the ship is inclined to the tail and left, and the residual oil on the first bilge plate 100 flows from right to left under the action of gravity and from the bow to the stern, and the residual oil is collected at the tail of the first bilge 110, and the residual oil collected at the tail of the first bilge 110 can be drained to the second bilge plate 200 through the angle arrangement of the first bilge 110.

Still more specifically, the second bilge plate 200 includes a second tilting bottom 210 and a second bilge 220 connected side by side in the length direction of the ship, wherein the second tilting bottom 210 is engaged to the inner side of the stern. The oil absorption well 300 is disposed at a junction between the second inclined bottom 210 and the second bilge 220, the second inclined bottom 210 is connected to the first inclined bottom 110, the second bilge 220 is connected to the first flat bilge 120, and the height of the second inclined bottom 210 is lower than that of the first flat bilge 120, i.e. the lower side edge of the second inclined bottom 210 is lower than that of the upper side edge of the second inclined bottom 210, and the lower side edge of the second inclined bottom 210 is connected to the upper side edge of the first flat bilge 120.

More specifically, the angle between the second tilting floor 210 and the plane of the second bilge 220 is 1 °. The above arrangement provides a drainage of the residual oil from the upper edge of the second inclined bottom 210 to the lower edge thereof, causing the residual oil to collect in a location near the suction well 300. The angle setting can ensure the structural stability of the bottom of the cabin and drain residual oil through calculation design.

Preferably, the second bilge 220 is located at a distance of 75mm from the plane in which the first bilge 120 is located. The above arrangement can form a stepped structure at the lower side edge of the second bilge 220 and the upper side edge of the first bilge 120, which can block the residual oil accumulated on the second bilge 220 from flowing back to the first bilge 120.

Optionally, the cabin bottom structure provided in this embodiment further includes a plurality of support ribs 400, where the plurality of support ribs 400 are arranged in an array matching the shape of the first and second bilge plates 100 and 200, are installed between the first and second bilge plates 100 and 200 and the bottom of the ship, and are configured to support the first and second bilge plates 100 and 200. The support aggregate 400 is inverted T-shaped, and improves the installation stability of the first bilge plate 100 and the second bilge plate 200 at the bottom of the ship.

Through the arrangement, a reliable leak-proof cabin is formed, so that goods such as chemicals and the like can be stored.

Still more specifically, the cabin provided in this embodiment further includes a cargo oil pump 30, where the cargo oil pump 30 is erected at the wellhead of the oil suction well 300 and configured to suck the residual oil in the bottom structure of the cabin, so as to improve the efficiency of cleaning the residual oil. The cargo oil pump 30 provided in this embodiment is a prior art, and the structure and principle of this embodiment are not described herein.
