Description

Technical Field

[0001] The present invention relates to the field of ships, and in particular to a roll reduction cabin and a ship comprising the same. Background Art

[0002] Due to the large width of large or ultra-large container ships and the trend of reducing service speed in recent years, the ship directional coefficient is getting larger and larger, which has increased from the early 0.6-0.65 to around 0.7, and the main dimensions of the ship type are also tending to be larger. Recently, designs with a total length exceeding 400m and a width exceeding 61.3m have also emerged. The initial stability high GM value brought about by the large-scale container ships has also increased significantly. The GM value, that is, the initial stability height (Metacentric Height), is a key indicator for measuring the stability of the ship. The increase in the GM value has greatly improved the safety of the ship and has great benefits for the damage stability (anti-sinking) of the ship. However, the increase in GM value also brings negative effects. When there are more heavy containers in the container ship's hold, the GM value of the entire ship is relatively large, which has an adverse effect on the loading of containers on the deck. Due to the high GM value of deck containers, short rolling period, high rolling frequency, and large force on the lashing system, the weight of the container stack on the deck and the vertical center of gravity height of the stack are limited, thereby affecting the loading flexibility and, in turn, the operating cost of the container ship.

[0003] Passenger ships and luxury cruise ships have a large number of passengers. Under the premise of ensuring the safety of the ship, the comfort of the passengers must be guaranteed. The larger the initial stability height GM value, the shorter the rolling period and the higher the rolling frequency of the ship due to the waves at sea and the external forces such as waves. Passengers are prone to seasickness, which leads to a decrease in the comfort experience of passengers. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the ship's rolling frequency is high and the period is short, which affects the loading capacity, and to provide a roll reduction cabin and a ship comprising the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention provides a roll reduction chamber, which comprises a chamber and a partition, wherein the chamber is connected to a hull, liquid is loaded in the chamber, a circulation channel is arranged in the chamber along a first direction, the first direction is the width direction of the ship, the partition extends from a first inner wall of the chamber to a second inner wall, the first inner wall and the second inner wall are symmetrically arranged along the first direction, the partition is movably connected to the first inner wall and / or the second inner wall, and the partition is used to open or close the circulation channel.

[0007] In this solution, the liquid in the anti-rolling tank can move in the flow channel arranged along the width direction of the ship, thereby providing damping in the width direction of the ship to offset the roll of the ship. The partition extending from the opposite first inner wall to the second inner wall can block the flow of liquid in the flow channel. When the ship's roll period is short and the roll frequency is high, the partition is movably connected to the first inner wall and / or the second inner wall, and the flow channel can be opened to allow the liquid to flow to offset the roll and reduce the roll amplitude of the ship, so that the roll period and roll frequency of the ship are within a reasonable range.

[0008] Preferably, the partition includes a first partition and a second partition, the first partition and the second partition are arranged opposite to each other; the first partition is movably connected to the first inner wall; and / or the second partition is movably connected to the second inner wall.

[0009] In this solution, the partition is divided into a first partition and a second partition, so that the partition can quickly open or close the flow channel.

[0010] Preferably, the anti-roll cabin also includes a first slide rail and a first slider that are slidably matched, one of the first slide rail and the first slider is connected to the first inner wall, and the other is connected to the first partition, and the extension direction of the first slide rail is the first direction or the second direction; wherein the second direction is at least perpendicular to the first direction; and / or, the anti-roll cabin also includes a second slide rail and a second slider that are slidably matched, one of the second slide rail and the second slider is connected to the second inner wall, and the other is connected to the second partition, and the extension direction of the second slide rail is the first direction or the second direction; wherein the second direction is at least perpendicular to the first direction.

[0011] In the present scheme, the first partition can slide along the first slide rail through the first slide rail and the first slider. When the first slide rail extends along the first direction or the second direction, the circulation channel is closed when the projection area of ​​the first partition and the second partition in the first direction is the largest, and the circulation channel is opened when the projection area of ​​the first partition and the second partition in the first direction is the smallest; similarly, the second slide rail and the second slider can slide along the second slide rail. When the second slide rail extends along the first direction or the second direction, the circulation channel is closed when the projection area of ​​the first partition and the second partition in the first direction is the largest, and the circulation channel is opened when the projection area of ​​the first partition and the second partition in the first direction is the smallest.

[0012] Preferably, the anti-roll cabin further comprises a power device, and the power device is used to drive the partition to open or close the circulation channel.

[0013] In this solution, since the partition is heavy, the partition can be opened or closed more conveniently and reliably through electric drive.

[0014] Preferably, there are a plurality of partitions, and the plurality of partitions are spaced apart along the first direction.

[0015] In this scheme, multiple partitions can divide the cabin into multiple small compartments, so that the liquid movement range of each small compartment is reduced when the partitions are closed. The number of partitions to be opened is selected according to the roll amplitude of the ship, and the liquid flow distance is controlled to control the damping provided by the anti-roll tank.

[0016] Preferably, the anti-roll tank further comprises a ballast tank, a ballast pump and a ballast pipeline, the ballast pipeline connects the ballast tank and the tank body, and the ballast pump is arranged on the ballast pipeline to control the connection between the ballast tank and the tank body.

[0017] In this scheme, liquid is stored in ballast tanks, and ballast pumps transport or pump liquid out of the tank. The capacity of the liquid in the tank can be flexibly adjusted. When a large roll reduction amplitude is required, the amount of liquid in the tank is increased, and when a small roll reduction amplitude is required, the amount of liquid in the tank is reduced, thereby flexibly controlling the ship's lateral stability GM value. By reasonably controlling the GM value, the cargo loading capacity of the ship is increased, the lashing force of the lashing parts is reduced, and the fatigue strength of the lashing parts is improved, which not only improves the cargo loading capacity of the container ship, but also improves the service life of the lashing parts.

[0018] The present invention also provides a ship, comprising a hull and the anti-rolling cabin as described above, wherein the anti-rolling cabin is connected to the hull.

[0019] In this solution, the liquid in the anti-rolling tank can move in the flow channel arranged along the width direction of the ship, thereby providing damping in the width direction of the ship to offset the roll of the ship. The partition extending from the opposite first inner wall to the second inner wall can block the flow of liquid in the flow channel. When the ship's roll period is short and the roll frequency is high, the partition is movably connected to the first inner wall and / or the second inner wall, and the flow channel can be opened to allow the liquid to flow to offset the roll and reduce the roll amplitude of the ship, so that the roll period and roll frequency of the ship are within a reasonable range.

[0020] Preferably, the anti-roll cabin is arranged below the deck of the ship.

[0021] In this solution, this arrangement design does not cause any loss of container space on the ship and does not affect the cargo capacity of the container ship.

[0022] Preferably, the axis of the anti-rolling cabin coincides with the axis of the hull.

[0023] In this solution, the overall anti-rolling effect of the ship can be further increased.

[0024] Preferably, there are multiple anti-roll cabins, and the multiple anti-roll cabins are connected in sequence.

[0025] In this solution, the damping provided by the roll stabilization cabin can be further increased, and at the same time, the roll stabilization effect generated by the water flow can form a combined force on the ship to the greatest extent, avoiding the roll stabilization effects of the staggered roll stabilization cabins from offsetting each other and reducing the overall roll stabilization effect of the ship.

[0026] The positive and progressive effects of the present invention are:

[0027] In the anti-rolling chamber and the ship including the anti-rolling chamber of the present invention, the liquid in the anti-rolling chamber can move in the flow channel arranged along the width direction of the ship, thereby providing damping in the width direction of the ship to offset the roll of the ship. The partition extending from the opposite first inner wall to the second inner wall can block the flow of liquid in the flow channel. When the ship's roll period is short and the roll frequency is high, the partition is movably connected to the first inner wall and / or the second inner wall, and the flow channel can be opened to allow the liquid to flow to offset the roll and reduce the roll amplitude of the ship, thereby making the roll period and roll frequency of the ship within a reasonable range.

[0043] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0044] This embodiment provides a roll reduction cabin 1, such as Figure 1-Figure 3 As shown, it includes a hull 2 ​​and a partition 5, the hull 2 ​​is connected to the hull 9, the hull 2 ​​is loaded with liquid, a circulation channel 8 is arranged in the hull 2 ​​along a first direction 10, the first direction 10 is the width direction of the ship, the partition 5 extends from the first inner wall 3 of the hull 2 ​​to the second inner wall 4, the first inner wall 3 and the second inner wall 4 are symmetrically arranged along the first direction 10, the partition 5 is movably connected to the first inner wall 3 and / or the second inner wall 4, and the partition 5 is used to open or close the circulation channel 8.

[0045] Thus, the liquid in the anti-rolling tank 1 can move in the flow channel 8 arranged along the width direction of the ship, thereby providing damping in the width direction of the ship to offset the roll of the ship. The partition 5 extends from the opposite first inner wall 3 to the second inner wall 4 to block the flow of liquid in the flow channel 8. When the ship's roll period is short and the roll frequency is high, the partition 5 is movably connected to the first inner wall 3 and / or the second inner wall 4, and the flow channel 8 can be opened to allow the liquid to flow to offset the roll and reduce the roll amplitude of the ship, so that the roll period and roll frequency of the ship are within a reasonable range.

[0046] For ease of explanation, the ship width direction is defined as left and right, the ship length direction is defined as front and back, and the ship height direction is defined as up and down.

[0047] The first inner wall 3 and the second inner wall 4 are the front and rear inner walls or the upper and lower inner walls of the cabin 2, and the partition 5 partitions the flow channel 8 from top to bottom or from front to back. The connection relationship between the partition 5 and the inner wall of the cabin 2 can include the following ways:

[0048] The first one is that the partition 5 is movably connected to the first inner wall 3 .

[0049] In the second case, the partition 5 is movably connected to the second inner wall 4 .

[0050] For the first and second embodiments, the movable connection method can be a hinge connection. The hinge is set on the first inner wall 3 or on the second inner wall 4. One side of the partition 5 is connected to the hinge for flipping. When the partition 5 is flipped to be parallel to the first direction 10, the circulation channel 8 is opened. When the partition 5 is flipped to be perpendicular to the first direction 10, the circulation channel 8 is closed.

[0051] The third type is that the partition 5 is movably connected to the first inner wall 3 and the second inner wall 4. Preferably, the partition 5 is movably connected to the first inner wall 3 and the second inner wall 4 at the same time.

[0052] For the third embodiment, the movable connection mode can be in the form of a rotating shaft or a slide rail. Among them, the movable connection mode of the rotating shaft is that the partition 5 is movably connected to the first inner wall 3 and the second inner wall 4 through a rotating shaft, and the rotating shaft is set in the middle position of the first inner wall 3 and the second inner wall 4. The rotating shaft coincides with the axis of the partition 5, that is, the partition 5 can rotate along its axis (rotating shaft), and the flow channel 8 is opened when the partition 5 is parallel to the first direction 10, and the flow channel 8 is closed when the partition 5 is perpendicular to the first direction 10.

[0053] The slide rail connection method is that the partition 5 is movably connected to the first inner wall 3 and the second inner wall 4 through the slide rail. The slide rail is set on the first inner wall 3, and can also be set on the second inner wall 4. The slide rail can also be set on the first inner wall 3 and the second inner wall 4. The partition 5 is set in the slide rail and can slide along the slide rail. When the partition 5 slides into the circulation channel 8, the circulation channel 8 is closed. When the partition 5 slides out of the circulation channel 8, the circulation channel 8 is opened.

[0054] The rail connection method can be further specified as follows: the partition 5 includes a first partition 6 and a second partition 7, a first slider is provided on the first partition 6, a first slide rail is provided on the first inner wall 3, a second slider is provided on the second partition 7, a second slide rail is provided on the second inner wall 4, the first slide rail and the first slider are slidably matched, and the second slide rail and the second slider are slidably matched. The first partition 6 can slide in a direction away from or close to the second partition 7 through the first slide rail and the first slider, and the second slide rail and the second slider. In other embodiments, the slide rail and the slider can be swapped.

[0055] Furthermore, the slide rail has two extending directions.

[0056] In the first type, the extension direction of the first slide rail and the second slide rail is the first direction 10, that is, the first partition 6 and the second partition 7 move left and right along the first direction 10, when the first partition 6 slides close to the second partition 7, the circulation channel 8 is closed, and when the first partition 6 slides away from the second partition 7, the circulation channel 8 is opened.

[0057] Preferably, the second type is adopted, wherein the extension direction of the first slide rail and the second slide rail is the second direction 11, wherein the second direction 11 is at least perpendicular to the first direction 10, that is, the second direction 11 can be the front-back direction or the up-down direction of the hull 9, such as Figure 1 As shown, in this embodiment, the first partition 6 and the second partition 7 slide up and down. When the first partition 6 slides close to the second partition 7, the circulation channel 8 is opened, and when the first partition 6 slides away from the second partition 7, the circulation channel 8 is closed. In other embodiments, the second direction 11 is the front-to-back direction, the first partition 6 and the second partition 7 slide back and forth, when the first partition 6 slides close to the second partition 7, the circulation channel 8 is opened, and when the first partition 6 slides away from the second partition 7, the circulation channel 8 is closed.

[0058] Specifically, the anti-rolling cabin 1 further includes a power device, which is used to drive the partition plate 5 to open or close the circulation channel 8.

[0059] Therefore, since the partition 5 is heavy, it can be opened or closed more conveniently and reliably by electric drive.

[0060] In this embodiment, the power device is an electric motor.

[0061] Specifically, there are a plurality of partitions 5 , and the plurality of partitions 5 are arranged at intervals along the first direction 10 .

[0062] Thus, multiple partitions 5 can divide the hull 2 ​​into multiple small chambers, so that the liquid movement range of each small chamber is reduced when the partitions 5 are closed, thereby reducing the impact of liquid flow on the hull 9 when the ship rolls less and no anti-rolling is required.

[0063] In this embodiment, if Figure 1 As shown, the number of the partitions 5 is 5 which is only a schematic expression, and the specific number can be adjusted according to the actual length of the ship, and this embodiment does not limit it.

[0064] Specifically, the roll stabilization tank 1 further includes a ballast tank, a ballast pump and a ballast pipeline. The ballast pipeline connects the ballast tank and the tank body 2 . The ballast pump is arranged on the ballast pipeline to control the connection between the ballast tank and the tank body 2 .

[0065] Therefore, by storing liquid in the ballast tank and using the ballast pump to transport or pump the liquid out of the tank body 2, the volume of the liquid in the tank body 2 can be flexibly adjusted.

[0066] In this embodiment, the anti-roll tank 1 also includes a liquid level sensor and a telemetry system display screen, and the liquid level sensor and the telemetry system display screen are electrically connected. The liquid level sensor is used to detect the liquid height in the cabin 2 and display the liquid height on the telemetry system display screen. The ballast pump is a pump that can perform bidirectional ballast. According to the required liquid level height, the crew manually adjusts the liquid capacity of the anti-roll tank 1. When a large anti-roll amplitude is required, the amount of liquid in the cabin 2 is increased, and when the anti-roll amplitude is small, the amount of liquid in the cabin 2 is reduced, thereby flexibly controlling the high GM value of the ship's transverse stability. By reasonably controlling the GM value, the cargo loading capacity of the ship is increased, the tying force of the tying parts is reduced, and the fatigue strength of the tying parts is improved, which not only improves the cargo loading capacity of the container ship, but also improves the service life of the tying parts. In other embodiments, the anti-roll tank 1 can also be provided with a control program, and the control program is electrically connected to the liquid level sensor and the ballast pump. According to the ship's draft, cargo, sea conditions and other information, and according to the liquid level and liquid level height requirements of the anti-rolling tank 1 set by the control program, the liquid level is automatically controlled and adjusted by adjusting the opening and closing of the ballast pump and the ballasting direction.

[0067] This embodiment further provides a ship, which comprises a hull 9 and the above anti-rolling cabin 1 , wherein the anti-rolling cabin 1 is connected to the hull 9 .

[0068] Thus, the liquid in the anti-rolling tank 1 can move in the flow channel 8 arranged along the width direction of the ship, thereby providing damping in the width direction of the ship to offset the roll of the ship. The partition 5 extends from the opposite first inner wall 3 to the second inner wall 4 to block the flow of liquid in the flow channel 8. When the ship rolls with a large amplitude, the partition 5 is movably connected to the first inner wall 3 and / or the second inner wall 4, and the flow channel 8 can be opened to allow the liquid to flow to offset the roll and reduce the roll amplitude of the ship. When the ship rolls with a small amplitude, the partition 5 can be closed to prevent the liquid from flowing, thereby achieving that the roll period and roll frequency of the ship are within a reasonable range under various conditions.

[0069] Specifically, the anti-rolling cabin 1 is arranged below the deck of the ship.

[0070] Therefore, this layout design does not cause any loss of container space on the ship and does not affect the cargo capacity of the container ship.

[0071] Specifically, the axis of the anti-rolling cabin 1 coincides with the axis of the hull 9 .

[0072] Thereby, the overall anti-rolling effect of the ship can be further increased.

[0073] In this embodiment, the axis of the anti-roll cabin 1 refers to the center of the anti-roll cabin 1 along the left and right direction of the hull 9, and the axis of the hull 9 refers to the center line of the hull 9 in the left and right direction, that is, the anti-roll cabin 1 is arranged in the center relative to the hull 9 in the left and right direction.

[0074] Specifically, there are multiple anti-rolling cabins 1, and the multiple anti-rolling cabins 1 are connected in sequence.

[0075] In this way, the damping provided by the roll stabilization cabin 1 can be further increased, and the roll stabilization effect produced by the water flow can be maximized to form a combined force on the ship, thereby avoiding the roll stabilization effects of the staggered roll stabilization cabins 1 from offsetting each other and reducing the overall roll stabilization effect of the ship.

[0076] In this embodiment, the plurality of anti-roll cabins 1 can be connected in sequence front to back, left to right, or up to down. Figure 1 and Figure 3 Two anti-rolling cabins 1 connected up and down are shown, but this is only a schematic expression and can be adjusted according to the actual needs of the ship, and this embodiment does not limit it.

[0077] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
