Description

Technical Field

[0001] The invention belongs to the technical field of ships and relates to a ship wind and wave resistant structure and a ship thereof. Background Art

[0002] In ocean transportation and offshore operations, ships face challenges from various severe sea conditions, among which wind and waves are one of the most threatening natural factors. Wind and waves not only increase navigation resistance and reduce navigation speed, but may also cause serious consequences such as damage to the hull structure, cargo displacement, and even ship capsizing. Therefore, improving the wind and wave resistance of ships is extremely important for ensuring navigation safety, protecting the lives and property of crew members, and maintaining the reliability and economy of maritime transportation.

[0003] Existing wind and wave resistance technologies for ships mainly include active and passive methods. The passive method usually involves optimizing the ship design to enhance its inherent stability and wave resistance, such as adjusting the ship's lines, increasing the stability height, and adopting a special hull shape (such as a catamaran or trimaran). These measures can improve the performance of ships in severe sea conditions to a certain extent. On the other hand, active wind and wave resistance technology relies more on mechanical or electronic equipment to control the ship's attitude in real time, such as the use of anti-roll fins, dynamic positioning systems, or adjustable ballast water systems. These technologies can effectively reduce the swaying of the ship, but at the same time they also increase the construction cost and maintenance complexity of the ship.

[0004] Although the above methods have improved the ability of ships to cope with severe sea conditions to a certain extent, the existing wind and wave resistance technology still has limitations under extreme conditions. For example, when encountering a severe storm, even the most advanced active control system may not be able to completely offset the impact of waves; and traditional passive designs often need to be achieved at the expense of other performance indicators (such as speed or cargo capacity), which is not always feasible in practical applications. In addition, with the continuous expansion of the scope of maritime activities and the growing demand for environmentally friendly ships, current technical means are difficult to meet the increasingly complex requirements of maritime operations. Summary of the invention

[0005] The object of the present invention is to provide a ship wind and wave resistance structure and a ship thereof, which can adaptively support the hull under extreme conditions, prevent the hull from capsizing, and increase the wind and wave resistance of the ship.

[0006] In order to solve the above technical problems, the present invention provides a ship wind and wave resistance structure, comprising a plurality of rotating seats arranged on the side of the ship, wherein the rotating seats are arranged in multiple rows from bottom to top on the side wall of the ship, each rotating seat is rotatably connected to a rotating connecting arm that can rotate outward, the length of the rotating connecting arm gradually increases from bottom to top, each rotating seat is rotatably connected to a pulling arm that can always remain parallel to the corresponding rotating connecting arm, each rotating connecting arm is provided with a resistance slide groove arranged along its length direction, each pulling arm is provided with a push-pull slider slidably connected to the corresponding resistance slide groove, and an elastic resistance member is arranged between each thrust slider and the corresponding resistance slide groove, so that when the rotating connecting arm and the corresponding pulling arm rotate upward, the rotating connecting arm slides relative to the corresponding pulling arm along the length direction, and the elastic resistance member generates resistance to prevent sliding;

[0007] Both sides of each rotating connecting arm are rotatably connected with resistance floats that can rotate to both sides. The lower end of each resistance float close to the ship is cut at an angle so that a gap is left between the lower end of each resistance float and the side wall of the ship. Both sides of each rotating connecting arm are provided with support nets on both sides of the upper direction of the corresponding resistance float, and the support net enables the corresponding resistance float to rotate outward only to be parallel with it.

[0008] By adopting the above technical solution, when the ship encounters extreme wind and waves, and the wind and waves cause the ship to tilt to one side, the resistance float on the tilted side is inserted into the water, and the buoyancy of the water pushes the resistance float to float up and rotate outward. When the resistance float floats up, it pushes the rotating connecting arm to rotate upward. During the upward rotation of the rotating connecting arm, the pulling arm is also driven to rotate upward in parallel. During the process, sliding along the length direction will occur between the rotating connecting arm and the pulling arm, so that the push-pull slider slides in the resistance slide groove to squeeze the elastic resistance member. The elastic reaction of the elastic resistance member rotates the connecting arm, presses the resistance float downward, and supports the rotating connecting arm between the side wall of the ship and the water surface, preventing the ship from tilting to one side. The amplitude of the tilt increases, and the resistance float is gradually increased upward to support the water surface, so as to prevent the ship from tilting as much as possible. If the waves hit the resistance float from the tilted side of the ship at this time, if the beating force is greater than the buoyancy, the waves will push the resistance floats on both sides of the rotating connecting arm to rotate downward with it as the center, filter the waves, reduce the impact of the waves, prevent the ship from further capsizing due to the impact of the waves, and improve the stability of the ship.

[0009] The present invention is further configured such that a rotating seat is provided with a circular rotating hole matching with the corresponding rotating connecting arm and a strip rotating hole matching with the corresponding pulling arm, the upper end of each rotating connecting arm is provided with a first rotating shaft rotatably connected with the corresponding circular rotating hole, and the upper end of each pulling arm is provided with a second rotating shaft sliding and rotating with the corresponding strip rotating hole, so that when the pulling arm rotates with the corresponding rotating connecting arm, the second rotating shaft can adaptively slide in the corresponding strip rotating hole, so that the pulling arm can always remain parallel to the corresponding rotating connecting arm.

[0010] The present invention is further configured such that each strip-shaped rotating hole is arranged along the height direction.

[0011] The present invention is further configured such that each elastic resistance member is a spring or elastic rubber.

[0012] The present invention is further configured such that each resistance floating plate is a hollow plate.

[0013] The present invention is further configured such that the cross section of each resistance chute is T-shaped, and the cross section of each push-pull slider is T-shaped matching the resistance chute.

[0014] The present invention also provides a ship, including a ship body, both sides of the ship body are provided with connection grooves, each rotating seat is arranged at the connection groove corresponding to one side of the ship body, and is characterized in that the interior of the ship body is a damping shock absorbing chamber, the damping shock absorbing chamber includes a front and rear shock absorbing chamber located in the middle, and two swing shock absorbing chambers respectively located on both sides of the front and rear shock absorbing chambers, the front and rear shock absorbing chambers are laterally provided with a transverse rotating connecting shaft, the transverse rotating connecting shaft is rotatably connected with a transverse rotating sleeve, and the transverse rotating sleeve is downwardly provided with front and rear damping swing plates, each swing shock absorbing chamber is close to the front and rear shock absorbing chambers and is provided with a longitudinal rotating connecting shaft arranged along the length direction of the ship body, each longitudinal rotating connecting shaft is rotatably connected with a longitudinal rotating sleeve, and each longitudinal rotating sleeve is downwardly provided with left and right damping swing plates, the upper part between the two swing shock absorbing chambers is connected with a guide groove that passes through the front and rear shock absorbing chambers laterally, the front and rear shock absorbing chambers and each swing shock absorbing chamber are filled with water, and the water level is not higher than the guide groove.

[0015] By adopting the above technical scheme, when the ship swings back and forth, the front and rear damping swing plates swing back and forth, and through the resonance effect, the amplitude of the ship's front and rear vibration is reduced, so that the ship can quickly recover stability; when the ship swings left and right, the two left and right damping swing plates swing together, and through the resonance effect, the amplitude of the ship's left and right vibration is reduced, so that the ship can quickly recover stability; and when the left and right damping swing plates rotate outward, the water in the swing damping chamber can be pushed outward, so that the water surface is higher than the water surface of the swing damping chamber on the other side, and the water will flow to the other swing damping chamber through the guide groove, shifting the center of gravity and preventing the ship from tipping.

[0016] The present invention is further configured such that an anti-collision rubber pad is provided on the inner wall of each swing damping chamber on one side close to the front and rear damping chambers.

[0017] The present invention is further configured such that a slanted water baffle is provided on one side of each swing damping chamber away from the front and rear damping chambers and flush with the guide groove and obliquely upward.

[0018] By adopting the above technical solution, through the inclined water baffle, when the hull rolls, the water in the roll shock absorbing chamber will not tilt to the tilted side, but flow to the middle position, so that the center of gravity of the ship is always relatively close to the middle as much as possible, and it is not easy to capsize. At the same time, under the obstruction of the inclined water baffle, the water in the roll shock absorbing chamber is more likely to transfer to the other side through the guide groove, further preventing the ship from rolling.

[0019] The present invention is further configured such that the bottom of each swing damping chamber is an arc-shaped bottom that matches the motion trajectory of the corresponding left and right damping swing plates.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, through the wind and wave resistant structure of the present invention, when the ship rolls over, the resistance float can be automatically deployed under the action of buoyancy, and supported between the ship and the water surface by the connection with the rotating connecting arm to prevent the ship from continuing to roll over. As the roll angle of the ship increases, the resistance float will also be deployed step by step, and gradually generate greater resistance to prevent the ship from rolling over, effectively preventing the ship from rolling over under extreme weather conditions, and improving the ship's wind and wave resistant ability;

[0022] Secondly, the resistance float of the present invention can automatically fold inwards when hit by waves, allowing the waves to pass through, thereby removing the impact force of the waves and effectively preventing the resistance float from being hit by waves and continuing to tilt when unfolded;

[0023] Thirdly, the ship of the present invention is provided with front and rear damping swing plates and left and right damping swing plates inside. When the ship vibrates under the action of wind and waves, the front and rear damping swing plates and left and right damping swing plates can swing adaptively according to the vibration of the ship, and utilize the resonance principle to reduce the amplitude of the ship's vibration, so that the ship can quickly restore stability;

[0024] Fourthly, when the ship of the present invention rolls over, the left and right damping swing plates rotate, cooperating with the inclined water retaining plates, to push the water on the inclined side upward to make it higher than the water on the other side, so that the water can be transferred to the other side through the guide groove, so that the center of the ship is shifted to the other side, counteracting the deviation of the ship, preventing the ship from rolling over, and further improving the ship's ability to resist wind and waves.

DETAILED DESCRIPTION

[0033] The following is a further detailed description of a ship wind and wave resistant structure and a ship thereof proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will become clearer. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. The same or similar figure numbers in the accompanying drawings represent the same or similar parts.

[0034] Example 1, reference Figure 1-4A ship wind and wave resistant structure comprises a plurality of rotating seats 1 arranged on the side of the ship, the rotating seats 1 are arranged in three rows from bottom to top on the side wall of the ship, each rotating seat 1 is rotatably connected to a rotating connecting arm 2 that can rotate outward, the length of the rotating connecting arm 2 gradually increases from bottom to top, and each rotating seat 1 is rotatably connected to a tension arm 3 that can always remain parallel to the corresponding rotating connecting arm 2. Each rotating seat 1 is provided with a circular rotating hole 4 matched with the corresponding rotating connecting arm 2 and a strip rotating hole 5 matched with the corresponding pulling arm 3. The upper end of each rotating connecting arm 2 is provided with a first rotating shaft 6 rotatably connected to the corresponding circular rotating hole 4. The upper end of each pulling arm 3 is provided with a second rotating shaft 7 that slides and rotates with the strip rotating hole 5. Each strip rotating hole 5 is arranged along the height direction, so that when the pulling arm 3 rotates with the corresponding rotating connecting arm 2, the second rotating shaft 7 can adaptively slide up and down in the corresponding strip rotating hole 5 to keep the distance between the rotating connecting arm 2 and the pulling arm 3 unchanged, so that the pulling arm 3 can always remain parallel to the corresponding rotating connecting arm 2. The length of the strip rotating hole 5 is such that the rotating connecting arm 2 can only rotate to be perpendicular to the side wall of the ship.

[0035] Each rotating connecting arm 2 is provided with a plurality of resistance grooves 8 arranged along its length direction, and the cross-section of each resistance groove 8 is T-shaped. The lowest rotating connecting arm 2 is provided with one resistance groove 8, the middle rotating connecting arm 2 is provided with two resistance grooves 8, and the uppermost rotating connecting arm 2 is provided with three resistance grooves 8 to gradually increase the resistance support from bottom to top. Each pulling arm 3 is provided with a push-pull slider 9 slidably connected to the corresponding resistance groove 8, and the cross-section of each push-pull slider 9 is T-shaped which matches the resistance groove 8. Through the connection between the resistance groove 8 and the push-pull slider 9, not only can the two slide relative to each other, but also the distance between the rotating connecting arm 2 and the pulling arm 3 can be kept unchanged. An elastic resistance member 10 is arranged between each thrust slider and the corresponding resistance slide groove 8. In the present embodiment, each elastic resistance member 10 is a spring. If the ship is a large ship, in order to obtain greater resistance support, the elastic resistance member 10 can select elastic rubber, so that when the rotating connecting arm 2 and the corresponding pulling arm 3 rotate upward, the rotating connecting arm 2 slides relative to the corresponding pulling arm 3 along the length direction, and the elastic resistance member 10 generates resistance to prevent sliding.

[0036] Both sides of each rotating connecting arm 2 are rotatably connected with a resistance float 11 that can rotate to both sides. Each resistance float 11 is a hollow plate. The lower end of each resistance float 11 is cut at an angle 12 on one side close to the ship, so that a gap is left between the lower end of each resistance float 11 and the side wall of the ship, so that water can enter through this gap, so that the resistance float 11 can generate outward buoyancy. Both sides of each rotating connecting arm 2 are provided with a support net 13 on both sides of the upper direction of the corresponding resistance float 11. The support net 13 allows the corresponding resistance float 11 to rotate outward only to be parallel with it, preventing the resistance float 11 from continuing to rotate upward and losing support.

[0037] Working principle: When a ship encounters extreme wind and waves, and the wind and waves cause the ship to tilt to one side, the resistance float 11 on the tilted side is inserted into the water, and the buoyancy of the water pushes the resistance float 11 to float upward and rotate outward. When the resistance float 11 floats upward, it pushes the rotating connecting arm 2 to rotate upward. During the upward rotation of the rotating connecting arm 2, the pulling arm 3 is also driven to rotate upward in parallel. During the process, sliding along the length direction will occur between the rotating connecting arm 2 and the pulling arm 3, so that the push-pull slider 9 slides in the resistance chute 8 to squeeze the elastic resistance member 10. The elastic reaction of the elastic resistance member 10 rotates the connecting arm 2, pressing the resistance float 11 downward, so that the rotating connecting arm 2 is supported between the side wall of the ship and the water surface, preventing the ship from tilting to one side. The amplitude of the tilt increases, and the resistance float 11 is gradually increased upward to support the water surface, preventing the ship from tilting as much as possible. If the waves hit the resistance float 11 from the tilted side of the ship at this time, if the hitting force is greater than the buoyancy, the waves will push the resistance floats 11 on both sides of the rotating connecting arm 2 to rotate downward with it as the center, filtering out the waves, reducing the impact of the waves, preventing the ship from further capsizing due to the impact of the waves, and improving the stability of the ship.

[0038] Example 2, reference Figure 5-7 A ship, a ship wind and wave resistant structure based on embodiment 1, comprises a ship body 14, both sides of the ship body 14 are provided with a connecting groove 15, and each rotating seat 1 is provided at the connecting groove 15 corresponding to one side of the ship body 14. The interior of the ship body 14 is a damping shock absorbing chamber, and the damping shock absorbing chamber comprises a front and rear shock absorbing chamber 16 located in the middle, and two swing shock absorbing chambers 17 located on both sides of the front and rear shock absorbing chambers 16, respectively. The front and rear shock absorbing chambers 16 and each swing shock absorbing chamber 17 are filled with water, and each swing shock absorbing chamber 17 is provided with an inclined water retaining plate 18 obliquely upward on a side away from the front and rear shock absorbing chambers 16. Through the inclined water retaining plate 18, when the hull rolls, the water in the swing shock absorbing chamber 17 will not tilt to the inclined side, but flow to the middle position, so that the center of gravity of the ship is always relatively close to the middle as much as possible, and it is not easy to capsize.

[0039] Three transverse rotating connecting shafts 19 are transversely arranged in the front and rear damping chambers 16, each of which is rotatably connected to a transverse rotating sleeve 20, and a front and rear damping swing plate 21 is arranged downwardly from the transverse rotating sleeve 20, so as to reduce the amplitude of the front and rear vibration of the ship through resonance. Each swing damping chamber 17 is provided with three longitudinal rotating connecting shafts 22 arranged along the length direction of the ship body 14 near the front and rear damping chambers 16, and each longitudinal rotating connecting shaft 22 is rotatably connected to a longitudinal rotating sleeve 23, and the longitudinal rotating sleeves 23 on the same side are downwardly connected to left and right damping swing plates 24, so as to reduce the amplitude of the left and right vibration of the ship through resonance. The inner wall of each swing damping chamber 17 close to the front and rear damping chambers 16 is provided with a plurality of anti-collision rubber pads 25, so that the left and right damping swing plates 24 play a buffering role when they swing and hit the side wall to prevent the inner wall from being damaged. The bottom of each swing damping chamber 17 is an arc-shaped bottom 26 that matches the movement trajectory of the corresponding left and right damping swing plates 24, so that water is not easy to flow back from the bottom. The upper part between the two swing damping chambers 17 is connected by two guide grooves 27 that pass horizontally through the front and rear damping chambers 16. The inclined water retaining plate 18 is arranged at an upward tilt at a position where the inner wall of the swing damping chamber 17 is flush with the guide groove 27, and the water level is not higher than the guide groove 27. The center of gravity is transferred through the guide groove 27 to prevent the ship from tipping.

[0040] Working principle: When the ship swings back and forth, the front and rear damping swing plates 21 swing back and forth, and through the resonance effect, the amplitude of the ship's front and rear vibration is reduced, so that the ship quickly recovers stability; when the ship swings left and right, the two left and right damping swing plates 24 swing together, and through the resonance effect, the amplitude of the ship's left and right vibration is reduced, so that the ship quickly recovers stability; and when the left and right damping swing plates 24 rotate outward, the water in the swing damping chamber 17 can be pushed outward, so that the water surface is higher than the water surface of the swing damping chamber 17 on the other side, and the water will flow to the other swing damping chamber 17 through the guide groove 27 to transfer the center of gravity. At the same time, under the obstruction of the inclined water retaining plate 18, the water level of the swing damping chamber 17 on the inclined side is higher, and more water can be transferred to the other side through the guide groove 27, further preventing the ship from tilting.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0042] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
