Description

Technical Field

[0001] The present invention relates to the technical field of ship construction, and in particular to a cabin bottom structure, a cabin and a ship. Background Art

[0002] For ships transporting chemicals, since the ship's cabins are loaded with more dangerous chemicals, the residual oil volume (the remaining chemical volume in the cabin) is required to be no more than 75L during unloading.

[0003] For ships with a grooved wall structure, the existing solution is to prevent cargo oil from accumulating in a position where the cargo oil pump cannot suck through reasonable arrangement of the cargo oil pump suction port and adding a large number of anti-accumulation plates in front of the grooved wall, so as to meet the residual oil requirement during unloading.

[0004] The above scheme for reducing the amount of residual oil has the following defects: First, the oil accumulation wells need to be arranged on the left and rear sides of the cabin as much as possible, which makes the arrangement extremely difficult. Second, the existing scheme is not very effective in eliminating the amount of residual oil. It is necessary to add a large number of anti-accumulation plates in front of the grooved wall to barely meet the residual oil requirement during unloading. The cost is extremely high and there are great technical risks. Third, adding a large number of anti-accumulation plates will reduce the capacity of the cargo hold. Fourth, adding anti-accumulation plates will increase the concentration of structural stress, and the grooved bulkhead will not be evenly stressed, which may cause fatigue problems. After long-term operation of the ship, it may even cause structural cracks. Fifth, the existing scheme has extremely high requirements on the suction capacity of the cargo oil pump, so the cost of sucking out residual oil is relatively high.

[0005] Therefore, there is an urgent need for a cabin bottom structure, a cabin and a ship to solve the above problems. Summary of the invention

[0035] Figure 1 A schematic structural diagram showing a cabin bottom structure provided by an embodiment of the present invention; Figure 2 Show Figure 1 The structure in the middle is marked as a cross-sectional view in the AA direction; Figure 3 Show Figure 1 The structure in the middle is marked as a cross-sectional view in the BB direction; Figure 4 Show Figure 1 The structure is marked as a cross-sectional view in the CC direction. Figure 1-Figure 4The present embodiment provides a cabin bottom structure, which specifically includes a first cabin bottom plate 100, a second cabin bottom plate 200 and an oil suction well 300. The first cabin bottom plate 100 is provided with a groove; the second cabin bottom plate 200 is installed in the groove and connected to the first cabin bottom plate 100, and the height of the second cabin bottom plate 200 is lower than that of the first cabin bottom plate 100; the oil suction well 300 is provided in the second cabin bottom plate 200, and a part of the second cabin bottom plate 200 is inclined toward the oil suction well 300, and the oil suction well 300 is configured to set up a cargo oil pump 30. In other words, the first cabin bottom plate 100 and the second cabin bottom plate 200 can form a drainage for the residual oil, so that the residual oil flows to the oil suction well 300 under the action of gravity. When unloading, the residual oil is gathered, which is convenient for suction, improves the residual oil removal efficiency, and avoids the problem of uneven force on the grooved bulkhead caused by adding an anti-accumulation plate.

[0036] Specifically, the first tank bottom plate 100 includes a first inclined bottom 110 and a first flat tank bottom 120 connected side by side in the width direction of the ship, wherein the first inclined bottom 110 is located on the left side of the first flat tank bottom 120. The height of the first flat tank bottom 120 is lower than that of the first inclined bottom 110, and the first inclined bottom 110 is inclined toward the first flat tank bottom 120, that is, the height of the right side edge of the first inclined bottom 110 is lower than that of the left side edge of the first inclined bottom 110, and the right side edge of the first inclined bottom 110 is connected to the left side edge of the first flat tank bottom 120. The above-mentioned groove is opened in the first flat tank bottom 120, and the adjacent two sides of the second tank bottom plate 200 are respectively connected to the first flat tank bottom 120 and the first inclined bottom 110, that is, the length of the first flat tank bottom 120 is smaller than the first inclined bottom 110, and the head of the first flat tank bottom 120 is flush with the head of the first inclined bottom 110. The above-mentioned groove is formed at the tail of the first flat tank bottom 120 and the tail of the first inclined bottom 110, and the sum of the lengths of the second tank bottom plate 200 and the first flat tank bottom 120 is equal to the length of the first inclined bottom 110.

[0037] Preferably, the angle between the first inclined bottom 110 and the plane where the first flat bilge 120 is located is 2°. The above arrangement can provide drainage for the residual oil remaining on the first bilge bottom plate 100. Specifically, when unloading, the ship will tilt toward the stern and the left side. At this time, the residual oil on the first bilge bottom plate 100 will flow from right to left under the action of gravity, and flow from the bow to the stern. The residual oil will gather at the stern of the first inclined bottom 110. Through the angle setting of the first inclined bottom 110, the residual oil gathered at the stern of the first inclined bottom 110 can be drained to the second bilge bottom plate 200.

[0038] More specifically, the second tank bottom plate 200 includes a second inclined bottom 210 and a second flat tank bottom 220 connected side by side along the length direction of the ship, wherein the second inclined bottom 210 is connected to the inner side of the stern. The oil suction well 300 is opened at the connection between the second inclined bottom 210 and the second flat tank bottom 220, the second inclined bottom 210 is connected to the first inclined bottom 110, and the second flat tank bottom 220 is connected to the first flat tank bottom 120, and its height is lower than the first flat tank bottom 120, that is, the lower side edge height of the second inclined bottom 210 is lower than the upper side edge height 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 tank bottom 120.

[0039] More specifically, the angle between the second inclined bottom 210 and the plane where the second flat tank bottom 220 is located is 1°. The above arrangement can provide drainage for the residual oil, drain the residual oil from the upper side edge of the second inclined bottom 210 to the lower side edge thereof, and make the residual oil gather at a position close to the oil suction well 300. The above angle arrangement is designed through calculation, which can not only ensure the structural stability of the tank bottom, but also drain the residual oil.

[0040] Preferably, the distance between the second flat tank bottom 220 and the plane where the first flat tank bottom 120 is located is 75 mm. The above arrangement can form a step structure at the lower edge of the second flat tank bottom 220 and the upper edge of the first flat tank bottom 120, and the step structure can block the residual oil accumulated on the second flat tank bottom 220 to prevent the residual oil from flowing back to the first flat tank bottom 120.

[0041] Optionally, the cabin bottom structure provided in this embodiment further includes a supporting frame 400, which is in multiple numbers, and the multiple supporting frames 400 are arranged in an array in a shape matching the first and second cabin bottom plates 100, 200, installed between the first and second cabin bottom plates 100, 200 and the bottom of the ship, and configured to support the first and second cabin bottom plates 100, 200. The supporting frame 400 is in an inverted T shape, which improves the installation stability of the first and second cabin bottom plates 100, 200 on the bottom of the ship.

[0042] The present embodiment also provides a cabin, which includes a first bulkhead 10 and a second bulkhead 20, wherein the second bulkhead 20 is arranged along the width direction of the ship, and the first bulkhead 10 is arranged along the length direction of the ship, and the first bulkhead 10 and the second bulkhead 20 are arranged to form a cabin side enclosure, and the cabin also includes a cabin bottom structure provided in the present embodiment, and the peripheral side of the cabin bottom structure is connected to the cabin side enclosure.

[0043] Specifically, the upper side edge of the first inclined bottom 110 and the upper side edge of the second flat bottom 220 are respectively connected to the first bulkhead 10 located at the rear of the cabin; the left side edge of the first inclined bottom 110 is connected to the second bulkhead 20 located on the left side of the cabin; the right side edge of the first flat bottom 120, the right side edge of the second flat bottom 220 and the right side edge of the second inclined bottom 210 are respectively connected to the second bulkhead 20 located on the right side of the cabin. The above arrangement forms a leakproof and reliable cabin for storing chemicals and other goods.

[0044] More specifically, the cabin provided in this embodiment further includes a cargo oil pump 30, which is mounted at the wellhead of the oil suction well 300 and is configured to suck the residual oil from the bottom structure of the cabin, thereby improving the removal efficiency of the residual oil. The cargo oil pump 30 provided in this embodiment is a prior art, and its structure and principle are not further described in this embodiment.
