Description

Technical Field

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

[0002] With the rapid development of the global marine economy, the high-tech development of marine transport equipment has received increasing attention. As the main means of marine transportation, the performance and safety of ships are directly related to the efficiency and reliability of marine transportation. However, ships will inevitably vibrate during navigation, which not only affects the comfort of the crew, but also may pose a threat to the structural safety of the ship.

[0003] During the voyage, the vibration problem of ships mainly comes from the continuous impact of waves. This natural phenomenon, as an inevitable part of navigation, poses a great challenge to the stability and safety of ships. However, most existing ships lack special vibration control devices. When ships are moving on the water, in bad weather, the waves will continuously hit the sides of the hull with strong force, which not only causes the vibration of the entire ship, but also causes the ship's plate to resonate. This vibration effect poses a severe test to the cargo fixing system on the ship's plate. Over time, the continuous vibration will gradually weaken the connection strength between the cargo and the ship's plate, eventually leading to Loose or even falling cargo may not only damage the cargo itself, but also pose a threat to the navigation safety of the ship. In addition, the impact of waves on the ship also brings another significant problem - the tilting of the hull. When the waves hit one side of the ship violently, that side will rise due to the force, causing the entire hull to tilt. This sudden tilt not only requires the crew to be vigilant at all times during navigation and hold on to the surrounding fixed objects tightly to prevent falling and injury, but also greatly reduces the crew's riding comfort. What's more serious is that the repeated tilting of the hull due to the impact of waves will further aggravate the crew's fatigue and discomfort, causing seasickness.

[0004] Furthermore, we disclose a ship vibration control device to meet the actual demand in the prior art that when a ship is traveling on the water, the impact of water waves will cause the ship to vibrate, the cargo fixing strength will decrease, the hull will tilt, and the crew's riding experience will be reduced.

[0016] Beneficial effects of the present invention:

[0017] 1.

[0018] 2. When the ship's vibration control device encounters wind and waves that cause the hull to shake, the set stabilization component can not only respond quickly, but also drive the stabilization plate to unfold through the electric telescopic rod, effectively disperse and resist the impact of waves, significantly reduce the vibration amplitude of the hull, and improve navigation stability. Specifically, when shaking occurs, the contact between the conductive layer and the power strip immediately starts the stabilization program. After unfolding, the stabilization plate can better fit the water surface fluctuations, which not only enhances the ship's anti-capsulation ability, but also optimizes the navigation posture and reduces the additional resistance caused by shaking. After the shaking stops, the automatic reset mechanism of the component relies on the spring buffer design to ensure the smooth retraction of the stabilization plate, which not only avoids false triggering, but also extends the service life of the equipment, while ensuring that the ship is not disturbed in any way during a stable navigation state.

Seal strip 9, both sides of the lower end of the hull 1 are provided with a center of gravity moving assembly, which is used to reduce the overall tilt angle of the hull 1 when the hull 1 is impacted by water waves. The center of gravity moving assembly includes a fixed plate 19 fixedly connected to the middle of the inner bottom surface of the hull 1, and both sides of the fixed plate 19 are slidably connected with counterweight blocks 39. The center of gravity moving assembly also includes push plates 3 located on both sides of the hull 1. When the water waves impact the push plates 3 and cause the push plates 3 to move, the counterweight blocks 39 will be driven to move synchronously, thereby realizing the overall center of gravity adjustment of the hull 1;

[0034] The device is provided with a shock-absorbing structure on the hull 1 and the deck 2, and uses a combination of a reinforcement rod 8 and a shock-absorbing spring seat 6 to effectively absorb the vibration energy of the hull 1, greatly reducing the impact of the vibration on the deck 2 and the superstructure, thereby ensuring smooth navigation, reducing the impact on the cargo connection strength on the deck 2, and reducing noise and structural fatigue. At the same time, the application of the sealing strip 9 further enhances the sealing performance between the hull 1 and the deck 2, prevents moisture penetration, and protects the internal structure from erosion. In addition, the device is also provided with a center of gravity moving component on both sides of the ship, which can automatically adjust the position of the counterweight block 39 according to the impact of water waves, instantly balance the center of gravity of the hull 1, effectively curb the tilt of the hull 1 caused by the action of waves, and enhance the maneuverability and safety of the ship in an environment of severe impact of water waves in severe weather. In summary, the ship vibration control device not only improves the dynamic performance of the ship, but also enhances its structural durability and environmental adaptability, providing a strong guarantee for navigation safety.

[0035] Further, such as Figures 1 to 5 As shown, the center of gravity moving assembly also includes a fixed box 5 fixedly connected to both sides of the lower end of the inner wall of the hull 1, and a rectangular groove is opened inside the two fixed boxes 5, and the rectangular groove runs through the hull 1. A sealing plate 15 is fixedly connected inside the rectangular groove, and a connecting rod 16 is slidably connected to the middle of the sealing plate 15. The end of the connecting rod 16 away from the fixed plate 19 is fixedly connected to the push plate 3, and both ends of the end surface of the sealing plate 15 close to the push plate 3 are fixedly connected to the return spring seat 14, and one end of the two return spring seats 14 is fixedly connected to the push plate 3, and the ends of the two connecting rods 16 close to the fixed plate 19 are fixedly connected to the connecting plate 17, and the two connecting plates 17 are close to the fixed plate 1 9 is fixedly connected with a rack 18 at one end, and the two racks 18 are fixedly connected to the connecting plate 17 in opposite directions. The two racks 18 are meshed with a reversing gear 21 on one side close to the counterweight block 39, and the lower ends of the two reversing gears 21 are engaged and rotatably connected with the hull 1. The two counterweight blocks 39 are located at the same height position as the reversing gear 21 on one side of the rack 18. A plurality of tooth grooves 20 are provided, and the two reversing gears 21 are meshed with the tooth grooves 20 on the two counterweight blocks 39 on the sides away from the rack 18. The middle parts of the two racks 18 are slidably connected to the limiting frames 22, and the lower ends of the two limiting frames 22 are fixedly connected to the hull 1;

[0036] When the ship encounters the impact of waves, the force of the waves first acts on the push plates 3 on both sides of the hull 1, pushing them to move inward. The movement of the push plates 3 is transmitted to the return spring seat 14 in the sealing plate 15 through the connecting rod 16. While being compressed, the return spring seat 14 also drives the synchronous movement of the rack 18 through the connecting rod 16 and the connecting plate 17. Since the two racks 18 are respectively fixedly connected to the connecting plate 17 and in opposite directions, they will move in opposite directions. This movement triggers the rotation of the reversing gear 21 meshing with the rack 18, and the rotation of the reversing gear 21 is in turn caused by the other side of the reversing gear 21 engaging with the tooth groove 20 on the counterweight block 39. The meshing drives the sliding of the counterweight 39 on the fixed plate 19. The moving direction of the counterweight 39 is the direction of the wave impact. This sliding adjustment of the counterweight 39 actually dynamically changes the center of gravity of the hull 1 according to the direction and strength of the wave impact, thereby effectively reducing the tilt angle of the hull 1 and enhancing the stability of the ship in severe sea conditions. At the same time, the setting of the limit frame 22 ensures the stability and accuracy of the rack 18 during movement, and the return spring seat 14 helps the push plate 3 and the connecting rod 16 and other components to return to their initial positions after the wave impact, so as to prepare for the next vibration control.

[0037] Further, such as Figures 1 to 3 , Figures 6 to 9As shown, a stabilizing assembly is also provided in the middle of the hull 1, and the stabilizing assembly is used to reduce the shaking intensity of the hull 1 when the hull 1 vibrates. The stabilizing assembly includes stabilizing plates 4 rotatably connected to both sides of the lower end of the middle of the hull 1, and the upper ends of the two stabilizing plates 4 are fixedly connected to a plurality of wave-blocking blocks 33, and the upper ends of the stabilizing plates 4 are fixedly connected to a fixed shaft 34, and the stabilizing plates 4 are rotatably connected to the hull 1 through the fixed shaft 34, and a rotating frame 35 is fixedly connected to one side of the fixed shaft 34, and the rotating frame 35 extends into the interior of the hull 1 away from the stabilizing plate 4. A movable groove is provided at the connection between the rotating frame 35 and the hull 1 to facilitate the movement of the rotating frame 35, and the connection between the inside of the movable groove and the rotating frame 35 A sealing telescopic pad is provided to prevent liquid from entering the interior of the hull 1 through the movable groove. The stabilizing component also includes a mounting plate 7 fixedly connected to one side of the middle reinforcement rod 8. An electric telescopic rod 32 is provided on one side of the lower end surface of the mounting plate 7. The lower end of the electric telescopic rod 32 is fixedly connected to a lifting plate 12. Both ends of the lifting plate 12 are rotatably connected to a first roller 31. The outer wall of the first roller 31 contacts the lower end surface of the rotating frame 35. Both sides of the inner wall of the hull 1 are fixedly connected to a fixing seat 23. The lower end of the fixing seat 23 is fixedly connected to a resistance spring 24. The lower end of the resistance spring 24 is fixedly connected to one side of the upper end surface of the rotating frame 35. Both sides of the middle of the lifting plate 12 are slidably connected There are guide rods 13, the lower ends of the two guide rods 13 are fixedly connected to the inner bottom surface of the hull 1, the stabilizing component also includes a rotating seat 25 fixedly connected to the middle part of the upper end surface of the mounting plate 7, the upper end of the rotating seat 25 is rotatably connected to the connecting rod 10, one side of the middle part of the lower end surface of the connecting rod 10 is fixedly connected to an extrusion spring 26, the lower end of the extrusion spring 26 is fixedly connected to the upper end surface of the mounting plate 7, the end of the connecting rod 10 away from the rotating seat 25 is rotatably connected to the second roller 38, one side outer wall of the second roller 38 contacts with a sliding rod 27, the upper end of the sliding rod 27 is slidably connected to the ship board 2 through a sliding bar, the lower end surface of the sliding rod 27 is located on one side of the connecting rod 10 and is fixedly connected to a guide block 36, the guide block 36 is an arc-shaped arrangement, a conductive layer 37 is arranged on one side of the middle of the outer wall of the sliding rod 27 close to the guide block 36, and power connection plates 28 are arranged on both ends of the side of the sliding rod 27 away from the guide block 36, and the adjacent surfaces of the two power connection plates 28 are in contact with the sliding rod 27, and the upper ends of the two power connection plates 28 are fixedly connected to the ship board 2, and a compression spring seat 29 is fixedly connected to the side of the sliding rod 27 away from the guide block 36, and a baffle 30 is fixedly connected to the end of the compression spring seat 29 away from the sliding rod 27, and the upper end of the baffle 30 is fixedly connected to the ship board 2, and a controller 11 is arranged in the middle of the inner bottom surface of the hull 1, and the controller 11 is electrically connected to the electric telescopic rod 32 and the two power connection plates 28;

[0038] When the ship encounters wind and waves during navigation, causing relative shaking between the hull 1 and the deck 2, this shaking will cause the connecting rod 10 to rotate around the rotating seat 25. The rotating end of the connecting rod 10 interacts with the sliding rod 27 through the arc-shaped guide block 36, pushing the sliding rod 27 to slide under the deck 2 along a preset path through the sliding bar. The sliding of the sliding rod 27 is one of the key actions. When the sliding rod 27 moves to a specific position, the conductive layer 37 on it contacts the power connection sheet 28. This contact action connects the circuit, and the electrical signal is transmitted. The controller 11 is passed to the controller 11, and the controller 11 responds immediately to control the electric telescopic rod 32 to start working. The extension of the electric telescopic rod 32 drives the height of the lifting plate 12 to drop. Since the first rollers 31 are arranged on both sides of the lifting plate 12, and the first rollers 31 are in contact with the rotating frame 35, when the lifting plate 12 drives the first rollers 31 to drop, the rotating frame 35 will flip downward under the elastic force of the resisting spring 24, and the elastic force of the resisting spring 24 will push the rotating frame 35 to rotate around the fixed axis 34, thereby driving the stabilizing plate 4 to flip, so that the stabilizing plate 4 cancels the contact with the hull 1. The stabilizing plates 4 are in a close contact state and unfolded, so that the stabilizing plates 4 can better adapt to the impact of waves and provide additional stability. At this time, when the hull 1 vibrates and shakes, the stabilizing plates 4 on both sides of the middle part of the hull 1 can play a better supporting role and reduce the vibration and shaking of the hull 1. When the shaking between the hull 1 and the deck 2 stops, the conductive layer 37 is separated from the power connection sheet 28, the circuit is disconnected, and the controller 11 stops sending working instructions to the electric telescopic rod 32. At this time, the electric telescopic rod 32 drives the lifting plate 12 to rise, and the resistance spring 24 also pushes the rotating frame 35 to reset, and the stabilizing plate 12 is stable. The fixed plate 4 is then reset to fit closely against the hull 1, ensuring that the normal navigation of the hull 1 is not affected. In addition, the arrangement of the compression spring seat 29 and the baffle 30 ensures that the sliding rod 27 can be smoothly and slowly reset after the shaking stops, and the conductive layer 37 has a longer length on the sliding rod 27. Only when the sliding rod 27 is fully reset will the conductive layer 37 not be in contact with the power connection plate 28, so that the sliding rod 27 will be fully reset only when there is no shaking between the hull 1 and the deck 2, thereby avoiding the false triggering of the electric telescopic rod 32 and improving the stability and durability of the entire system.
