Description

Technical Field

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

[0002] In large ship design, roll stabilization tanks are crucial for enhancing navigational stability. They operate by generating a moment opposite to the ship's roll through the periodic sloshing of the water within the tanks, effectively suppressing the ship's sway. Traditional roll stabilization tank systems are typically arranged symmetrically on both sides of the hull, with the two tanks connected by a connecting pipe. When the ship rolls, water is redistributed between the two tanks, driven by pumps or the water's own gravity. Wave disturbance torque is offset by adjusting the difference in center of gravity between the two water bodies.

[0003] However, the water distribution process takes a long time, making instantaneous adjustment difficult. This lag results in the system being unable to respond promptly to sudden roll events, such as irregular waves in severe sea conditions, affecting the ship's stability in complex sea conditions. Summary of the Invention

[0007] A guide mechanism, at least one of which is provided in the hull, comprising a downwardly concave arc-shaped guide structure, the guide structure being located below the left and right stabilization tanks, and the axis of the guide structure being parallel to or coincident with the longitudinal centerline of the hull;

[0008] Ballast member, at least one ballast member is slidably connected to one of the guide structures, and the ballast member is located between the left anti-roll cabin and the right anti-roll cabin.

[0009] As a preferred embodiment, the ship further includes a stopping mechanism, which is connected to the guide structure and is configured to stop the ballast member in the anti-roll position from sliding toward the initial position; the initial position is the position of the guide structure relative to the longitudinal centerline of the hull when the hull is horizontal; the anti-roll position is the position of the ballast member when it approaches the left anti-roll tank or the right anti-roll tank when the hull is tilted.

[0010] As a preferred embodiment, the stopping mechanism includes a stop block and an elastic member; the guide structure has a mounting groove, and in the length direction of the guide structure, the mounting groove has a first side wall close to the initial position and a second side wall away from the initial position, the first end of the stop block is hinged to the first side wall, and the elastic member is arranged in the mounting groove to apply elastic force to the second end of the stop block, so that at least part of the second end of the stop block protrudes out of the mounting groove; the stop block protruding out of the mounting groove is stopped by the ballast member.

[0011] As a preferred embodiment, the second end of the stop block has a guide portion, which is a guide bevel or a guide radius. The hull drives the ballast part to swing upward, and the ballast part presses the guide bevel or the guide radius to press the stop block protruding out of the mounting groove into the mounting groove.

[0012] As a preferred solution, a plurality of the stopping mechanisms are connected to one guide structure, and the stopping mechanisms are arranged at intervals along the length direction of the guide structure.

[0015] As a preferred solution, the ship further includes a control system and a gyroscope, and the first bidirectional water pump, the second bidirectional water pump and the gyroscope are all electrically connected to the control system;

[0016] When the gyroscope detects that the hull tilts right, the control system controls the first bidirectional water pump to transfer water in the left anti-roll tank to the inner cavity, and controls the second bidirectional water pump to transfer water in the inner cavity to the right anti-roll tank;

DETAILED DESCRIPTION

[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0032] like Figures 1 to 6As shown, a preferred embodiment of the ship of the present invention includes a hull 1, a guide mechanism 3 and a ballast member 4. The hull 1 is provided with a left anti-roll tank 21 and a right anti-roll tank 22 arranged relatively spaced apart along the width direction of the hull 1, and a ballast water regulating system for regulating the amount of water in the left anti-roll tank 21 and the right anti-roll tank 22; at least one guide mechanism 3 is provided in the hull 1, and the guide mechanism 3 includes a downwardly concave arc-shaped guide structure, the guide structure is located below the left anti-roll tank 21 and the right anti-roll tank 22, and the axis of the guide structure is parallel to or coincides with the longitudinal centerline of the hull 1; at least one ballast member 4 is slidably connected to one guide structure, and the ballast member 4 is located Between the left anti-roll tank 21 and the right anti-roll tank 22; when the hull 1 tilts toward the right anti-roll tank 22, at least one ballast member 4 slides toward the right anti-roll tank 22; when the hull 1 tilts toward the left anti-roll tank 21, at least one ballast member 4 slides toward the left anti-roll tank 21. The ballast member 4 slides to the left anti-roll tank 21 or the right anti-roll tank 22, which can instantly increase the weight on the left or right side of the hull 1 and improve the hysteresis of the roll of the hull 1; the ballast member 4 mainly responds to the high-frequency shaking of the hull 1, while the left anti-roll tank 21 and the right anti-roll tank 22 can handle the low-frequency and large-scale tilting of the hull 1, ensuring the stability of the hull 1. The ballast member 4 and the anti-roll tank work together to improve the overall anti-roll performance of the hull 1. Among them, the guide mechanism 3 includes, in addition to the guide structure, a support member for supporting the guide structure. The lower end of the support member is connected to the hull 1, and at least part of the guide structure is fixed to the support member.

[0033] It should be noted that, in this embodiment, the starboard tilt of the hull 1 refers to a tilted state in which the right side of the hull 1 is lower and the left side is higher; the port tilt of the hull 1 refers to a tilted state in which the left side of the hull 1 is lower and the right side is higher.

[0034] In this embodiment, the ship further includes a stopping mechanism 5, which is connected to the guide structure and configured to prevent the ballast member 4 in the anti-roll position from sliding toward the initial position; the initial position is the position of the guide structure relative to the longitudinal centerline of the hull 1 when the hull 1 is horizontal; the anti-roll position is the position of the ballast member 4 when the hull 1 is tilted and close to the left anti-roll tank 21 or the right anti-roll tank 22. When the hull 1 is tilted by waves, the righting torque generated by traditional passive anti-roll tanks often lags behind the wave torque by 15° to 20° due to factors such as liquid flow inertia. The stopping mechanism 5 keeps the ballast member 4 in the tilted lateral position, forming a continuous reverse torque, which can ensure that the righting torque continues to act until the end of the wave cycle, thereby reducing the phase difference in stability adjustment.

[0035] The stopping mechanism 5 includes a stopper 51 and an elastic member 52. The guide structure has a mounting slot 311. The mounting slot 311 has a first sidewall proximal to the initial position and a second sidewall distal to the initial position in the longitudinal direction of the guide structure. The first end of the stopper 51 is hinged to the first sidewall. The elastic member 52 is disposed in the mounting slot 311 to apply an elastic force to the second end of the stopper 51, causing at least a portion of the second end of the stopper 51 to protrude out of the mounting slot 311. The stopper 51 protruding out of the mounting slot 311 is stopped by the ballast member 4. Specifically, the elastic member 52 is a compression spring disposed near the second sidewall. One end of the elastic member 52 is connected to the bottom wall of the mounting slot 311, and the other end of the elastic member 52 is connected to the second end of the stopper 51 to push at least a portion of the second end of the stopper 51 out of the mounting slot 311.

[0036] Specifically, under the action of the elastic member 52, the portion of the stopper 51 protruding from the mounting groove 311 is in an inclined state, the first end of the stopper 51 is close to the center line of the hull 1, the first end of the stopper 51 is lower, and the second end of the stopper 51 is higher. When the hull 1 tilts, the ballast member 4 slides from the center line of the hull 1 to the left and then to the right, and the sliding ballast member 4 will impact the stopper 51. The inclined state of the stopper 51 and the setting of the elastic member 52 enable the stopper 51 to dissipate the impact energy of the ballast member 4, and the compression characteristics of the spring Under the action, when the ballast member 4 just impacts the first end of the stopper 51, the resistance of the stopper 51 to the ballast member 4 is relatively small. As the ballast member 4 gradually squeezes the stopper 51, the compression of the elastic member 52 gradually increases, and the elastic force of the elastic member 52 on the second end of the stopper 51 gradually increases, and the buffering resistance of the stopper 51 to the ballast member 4 also gradually increases. After the ballast member 4 completely slides past the second end of the stopper 51, under the action of the elastic member 52, the second end of the ballast member 4 extends out of the mounting groove 311 again, thereby stopping the ballast member 4. Therefore, the stopping mechanism 5 of this embodiment not only stops the ballast member 4, but also dissipates the impact energy of the ballast member 4 step by step, thereby improving the stability of the ballast member 4 during operation.

[0037] After the hull 1 tilts right to the maximum angle, the hull 1 needs to be straightened or switched to a left tilt. When the hull 1 is straightened or tilted left, the hull 1 drives the ballast 4 to swing upward. In this embodiment, the second end of the stopper 51 has a guide portion 511. The guide portion 511 is a guide bevel or guide fillet. The hull 1 drives the ballast 4 to swing upward. The ballast 4 presses the guide bevel or guide fillet, pressing the stopper 51 protruding from the mounting groove 311 into the mounting groove 311, thereby releasing the stopper 51 from blocking the ballast 4, allowing the ballast 4 to slide smoothly to its initial position or left tilt. In this embodiment, through the structural design of the stopper 51, the stopper 51 can be realized or released without the need to set an active drive device to drive the stopper 51 to switch states. In addition, the stopper 51 also has the function of consuming the impact energy of the ballast 4.

[0038] Furthermore, in this embodiment, a plurality of stop mechanisms 5 are connected to a single guide structure, and the stop mechanisms 5 are spaced apart along the length of the guide structure. The provision of multiple stop mechanisms 5 not only increases the amount of impact energy dissipated by the stoppers 51 on the ballast member 4, but also enables the ballast member 4 to be stopped at the corresponding stopper 51 according to the tilt angle of the hull 1.

[0039] In this embodiment, the ballast unit 4 has an inner cavity, and the ballast water regulation system includes a first bidirectional water pump 61 and a second bidirectional water pump 62. The first bidirectional water pump 61 has two ends connected to the left stabilization tank 21 and the inner cavity, respectively, while the second bidirectional water pump 62 has two ends connected to the inner cavity and the right stabilization tank 22. The first and second bidirectional water pumps 61 and 62 can adjust not only the water volume difference between the left and right stabilization tanks 21 and 22 but also the water volume in the inner cavity, allowing the weight of the ballast unit 4 to be flexibly adjusted to match the roll level of the hull 1. This prevents instability of the hull 1 caused by excessive ballast unit 4 weight, and also prevents inadequate roll reduction caused by insufficient ballast unit 4 weight. In this embodiment, there are multiple ballast parts 4 and guide mechanisms 3. A ballast part 4 is slidably connected to a guide structure, and the guide structures are arranged at intervals along the length direction of the hull 1. The ballast part 4 on a single guide structure can be set to be able to slide to the left to a position close to the left anti-roll tank 21, and to the right to a position close to the right anti-roll tank 22, that is, the guide structures are arranged symmetrically on the left and right. When the hull 1 tilts to the right, the ballast part 4 can slide to the right on the guide structure to a position close to the right anti-roll tank 22. When the hull 1 tilts to the left, the ballast part 4 can slide to the left on the same guide structure to a position close to the left anti-roll tank 21.

[0040] In some embodiments of the present application, Figure 3As shown, the ballast members 4 on the two adjacent guide structures can also be set so that one can only slide to the left and the other can only slide to the right. In this case, each guide structure only has an area for the ballast member 4 to slide on one side of the longitudinal center line of the hull 1, and the other side is set as an installation area into which the ballast member 4 cannot slide. This arrangement facilitates the arrangement of water pumps and other devices in the installation area. When such a guide mechanism 3 is used, a third bidirectional water pump 63 can be set between the two adjacent ballast members 4, and the two ends of the third bidirectional water pump 63 are respectively connected to the inner cavities of the two adjacent ballast members 4. With this arrangement, only three bidirectional water pumps need to be set for the two adjacent ballast members 4. Compared with the arrangement in which a first bidirectional water pump 61 and a second bidirectional water pump 62 are respectively set for each ballast member 4, one bidirectional water pump can be saved. When such a guide mechanism 3 is used, the two adjacent ballast members 4 constitute a group of ballast components. For the convenience of description, the two ballast parts 4 of a group of ballast components are named as the first ballast part and the second ballast part respectively, and the two adjacent guide mechanisms 3 are named as the first guide mechanism and the second guide mechanism respectively. The first guide mechanism is only provided with a first slide groove on the right half, and the first ballast part is slidably connected to the first slide groove. The second guide mechanism is only provided with a second slide groove on the left half, and the second ballast part is slidably connected to the second slide groove. One end of the first two-way water pump 61 is connected to the left anti-roll tank 21, and the other end of the first two-way water pump 61 is connected to the inner cavity of the second ballast part through the first hose 64. One end of the third two-way water pump 63 is connected to the inner cavity of the second ballast part, and the other end of the third two-way water pump 63 is connected to the inner cavity of the first ballast part through the third hose 66. One end of the second two-way water pump 62 is connected to the inner cavity of the first ballast part through the second hose 65, and the other end of the second two-way water pump 62 is connected to the right anti-roll tank 22.

[0041] In this embodiment, a guide mechanism 3 includes two arc-shaped guide rails 31 arranged in parallel and spaced apart along the length direction of the hull 1, and both guide rails 31 are provided with a slide groove 312. The ballast part 4 includes a box body 41 and two sliders 42 fixed at the lower end of the box body 41. The two sliders 42 are respectively slidably guided and connected in the corresponding slide groove 312. The installation groove 311 is arranged in the bottom wall of the slide groove 312. The stop block 51 arranged in the installation groove 311 can prevent the slider 42 from sliding in the slide groove 312.

[0042] In this embodiment, the ballast water regulation system includes a first hose 64 and a second hose 65. One end of the first hose 64 is connected to the first two-way water pump 61, and the other end of the first hose 64 is connected to the ballast member 4. One end of the second hose 65 is connected to the ballast member 4, and the other end of the second hose 65 is connected to the second two-way water pump 62. The first hose 64 and the second hose 65 are able to adaptively deform according to the position of the ballast member 4 during movement, reducing the impact on the position of the ballast member 4.

[0043] In this embodiment, the ship further includes a control system and a gyroscope, and the first two-way water pump 61, the second two-way water pump 62 and the gyroscope are all electrically connected to the control system; when the gyroscope detects that the hull 1 is tilting to the right, the control system controls the first two-way water pump 61 to transfer the water in the left stabilization tank 21 to the inner cavity, and controls the second two-way water pump 62 to transfer the water in the inner cavity to the right stabilization tank 22, thereby increasing the amount of water in the right stabilization tank 22; when the gyroscope detects that the hull 1 is tilting to the left, the control system controls the first two-way water pump 61 to transfer the water in the inner cavity to the left stabilization tank 21, and controls the second two-way water pump 62 to transfer the water in the right stabilization tank 22 to the inner cavity, thereby increasing the amount of water in the left stabilization tank 21.

[0044] Furthermore, when the gyroscope detects that the hull 1 is tilting to the right, the tilt angle continues to increase, and the angular velocity is positive, it means that the ballast member 4 is sliding to the right. The control system controls the working power of the second two-way water pump 62 to be greater than the working power of the first two-way water pump 61. In this way, the amount of water flowing out of the inner cavity to the right anti-roll tank 22 is greater than the amount of water flowing into the inner cavity of the left anti-roll tank 21. During the movement of the ballast member 4, the weight of the ballast member 4 is reduced, and the amount of water in the right anti-roll tank 22 is increased. The reduction in the weight of the ballast member 4 can reduce The impact energy of the ballast member 4 and the increase in the water volume in the right ballast tank can ensure the anti-rolling effect of the anti-rolling tank; when the gyroscope detects that the hull 1 tilts to the left, the tilt angle continues to increase and the angular velocity is positive, the control system controls the working power of the second two-way water pump 62 to be lower than the working power of the first two-way water pump 61, so that the amount of water flowing out of the inner cavity to the left anti-rolling tank 21 is greater than the amount of water flowing into the inner cavity of the right anti-rolling tank 22, reducing the weight of the ballast member 4 during its movement and increasing the water volume in the left anti-rolling tank 21.

[0045] In this embodiment, when the gyroscope detects that the hull 1 is listing to right and the angular velocity is zero, it indicates that the hull 1 has listed to right to the maximum extent. At this time, the control system controls the first two-way water pump 61 to shut down and controls the second two-way water pump 62 to pump water from the right anti-roll tank 22 into the inner cavity, thereby increasing the weight of the ballast member 4 located on the right side of the hull 1. The increased weight of the ballast member 4 facilitates the ballast member 4 to press the second end of the stopper 51 on the left side of the ballast member into the installation groove 311, thereby allowing the ballast member 4 to slide to the left side of the hull 1 when the hull 1 lists to port. In this state, the sum of the water volume in the right anti-roll tank 22 and the ballast member 4 remains unchanged. When the gyroscope detects that the hull 1 is listing to port and the angular velocity is zero, the control system controls the second two-way water pump 62 to shut down and controls the first two-way water pump 61 to pump water from the left anti-roll tank 21 into the inner cavity. Similarly, the increased weight of the ballast member 4 facilitates the ballast member 4 located on the left side of the hull 1 to press the second end of the corresponding stopper 51 into the corresponding installation groove 311.

[0046] In summary, the ship hull 1 of the present invention is provided with a left anti-roll tank 21 and a right anti-roll tank 22 arranged relatively spaced apart along the width direction of the hull 1, and a ballast water regulating system for regulating the amount of water in the left anti-roll tank 21 and the right anti-roll tank 22; at least one guide mechanism 3 is provided in the hull 1, and the guide mechanism 3 includes a downwardly concave arc-shaped guide structure, the guide structure is located below the left anti-roll tank 21 and the right anti-roll tank 22, and the axis of the guide structure is parallel to or coincides with the longitudinal center line of the hull 1; a guide structure is slidably connected to the left anti-roll tank 21 and the right anti-roll tank 22. There is at least one ballast member 4, which is located between the left anti-roll tank 21 and the right anti-roll tank 22; when the hull 1 tilts toward the right anti-roll tank 22, at least one ballast member 4 slides toward the right anti-roll tank 22; when the hull 1 tilts toward the left anti-roll tank 21, at least one ballast member 4 slides toward the left anti-roll tank 21. The ballast member 4 slides to the left anti-roll tank 21 or the right anti-roll tank 22, which can instantly increase the weight on the left or right side of the hull 1 and improve the hysteresis of the roll of the hull 1; the left anti-roll tank 21 and the right anti-roll tank 22 ensure the stability of the hull 1.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
