Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to a hull with high stability. Background Art

[0002] Hull stability is one of the core issues in ship design and manufacturing, especially in severe weather conditions, where hull stability is directly related to ship safety and transportation efficiency. Traditional hull design often relies on hull shape, ballast tanks, and container fixing methods to improve stability, but these methods may still face challenges under certain extreme conditions.

[0003] The ability of existing hulls to maintain steady navigation in severe sea conditions such as wind and waves needs to be improved. When the ship is subjected to the lateral force of waves, there is a lack of effective auxiliary stabilization means and it is prone to large-scale shaking, which not only affects the comfort of crew and passengers, but may also pose a threat to the safety of cargo on board and the maneuverability of the ship. In addition, the protective measures of existing hulls have certain limitations when dealing with collision risks. Most hulls are only equipped with simple fixed anti-collision structures, such as conventional rubber fenders, which are fixed in position and have limited buffering capacity.

[0004] To this end, we provide a high stability hull to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a hull with high stability in view of the problems of the background technology.

[0011] As a further optimization scheme of the present invention, a bottom frame body is fixedly provided at the bottom of the hull, and two symmetrically distributed movable plates are slidably provided in the bottom frame body, and a second connecting mechanism for connecting the rubber protrusions is fixedly provided on the movable plates; the bottom frame body is also provided with a translation mechanism for driving the two movable plates to move simultaneously to drive the rubber protrusions on both sides to extend outward.

[0012] As a further optimization solution of the present invention, the mounting portion is further provided with a plurality of second strip-shaped through holes which are distributed at equal intervals and are used for the second connecting mechanism to pass through, and the second strip-shaped through holes are distributed alternately with the first strip-shaped through holes.

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention can realize the movement of rubber protrusions between different positions by arranging a conveyor to adapt to various scenarios. For example, when a ship approaches a dock or may collide with other objects, the rubber protrusions are rotated to the upper end of the side wall of the ship body to provide buffering when a collision occurs. When the rubber protrusions are rotated to the side, it is also convenient to clean them to avoid a large amount of debris attached to the rubber protrusions. When the ship is affected by external forces such as wind, waves, and water flow during navigation and rolls or sways, the rubber protrusions are rotated to the bottom of the ship body to change the water flow pattern at the bottom of the ship, thereby suppressing the roll and sway of the ship body, making the navigation of the ship more stable and improving the stability and maneuverability of the ship.

[0016] 2. The present invention provides a translation mechanism, a first connecting mechanism and a second connecting mechanism so that the two rubber protrusions can extend outward to increase the area between the two rubber protrusions. When the ship encounters severe sea conditions such as big waves and strong currents during navigation, the extended rubber protrusions can change the water flow pattern around the ship to increase the water resistance on the side of the ship, thereby further improving the suppression effect on the roll and pitch of the ship.

[0027] Embodiment 1

[0028] In order to solve the problem that the existing hull is prone to tilt or sway under the influence of external forces such as wind, waves, and water currents during navigation, and the navigation stability and safety of the ship need to be improved, please refer to Figure 1-Figure 2 A high-stability hull provided by the present invention comprises a hull 1, on both side walls of the hull 1 are fixedly provided with conveyors 2 extending to the bottom of the hull 1, a mounting frame 3 is fixedly provided on the transmission chain plate of the conveyor 2, and guide rails 201 are also fixedly provided on both side walls of the hull 1, the mounting frame 3 is slidably matched with the guide rails 201, and a rubber protrusion 4 and a first connecting mechanism 5 for locking the rubber protrusion 4 are provided on the mounting frame 3; the rubber protrusion 4 is displaced to the upper end of the side wall of the hull 1 with the conveyor 2 to form an anti-collision component, and the rubber protrusion 4 is displaced to the bottom of the hull 1 with the conveyor 2 to form a ship navigation stability component. The rubber protrusion 4 can be stopped at different positions of the hull 1 by the conveyor 2 to adapt to various scenarios. For example, when the ship is close to the dock or may collide with other objects, the rubber protrusion 4 is rotated to the upper end of the side wall of the hull 1, which can provide buffering when the collision occurs, reduce the damage to the hull 1, and protect the structure of the hull 1 and the safety of the equipment and personnel on board. When the ship is affected by external forces such as wind, waves, and water flow during navigation and rolls or sways, the rubber protrusion 4 is rotated to the bottom of the hull 1 to change the water flow pattern at the bottom of the ship, increase the lateral resistance of the ship to a certain extent, and play a role in suppressing the roll and sway of the hull 1, making the ship's navigation more stable, improving the stability and maneuverability of the ship, and also reducing the turbulence and vortex generation of the water flow, reducing the water resistance of the ship during navigation, improving the propulsion efficiency of the ship, and reducing fuel consumption and operating costs.

[0029] like Figure 3 As shown, the rubber protrusion 4 includes a mounting portion 401 and a rubber portion 402 fixed to the bottom of the mounting portion 401. The rubber portion 402 is made of high-performance rubber materials, such as nitrile rubber, chloroprene rubber, etc., which have good wear resistance, corrosion resistance, weather resistance and elasticity, so as to maintain stable performance in long-term seawater immersion and harsh marine environments. Other components can be made of high-strength stainless steel or aluminum alloy materials to ensure that the components will not rust or deform during long-term use in seawater. The mounting portion 401 is provided with a plurality of first strip through holes 403 for the first connecting mechanism 5 to pass through, which are evenly distributed.

[0030] like Figure 4-Figure 5 As shown, the first connecting mechanism 5 includes a plurality of first rotating shafts 501 corresponding to the first strip-shaped through holes 403 one by one, two first strip-shaped rods 502 are fixedly provided on the first rotating shaft 501, a first bearing seat 503 for supporting its rotation is provided at the end of the first rotating shaft 501, a first gear 504 is also fixedly sleeved on the first rotating shaft 501, a first rack 505 meshing with the first gear 504 is provided on the side of the first gear 504, a first electric push rod 506 for driving the first rack 505 to move is provided at the end of the first rack 505, and the first electric push rod 506 and the first bearing seat 503 are both fixed on the mounting frame 3; the first strip-shaped rod 502 rotates to a position perpendicular to the first strip-shaped through hole 403 to lock the rubber protrusion 4 to the mounting frame 3, and the first strip-shaped rod 502 rotates to a position overlapping with the first strip-shaped through hole 403 to release the locking state of the rubber protrusion 4 and the mounting frame 3.

[0031] When in use, the first rack 505 is driven to move by the first electric push rod 506, the first rack 505 drives the first gear 504 to rotate, the first gear 504 drives the first rotating shaft 501 to rotate, and the first rotating shaft 501 drives the first strip rod 502 to rotate. When the first strip rod 502 rotates to a position perpendicular to the first strip through hole 403, the rubber protrusion 4 can be restricted in the mounting frame 3 due to the obstruction of the first strip rod 502, so that when the mounting frame 3 moves with the conveyor 2, it can drive the rubber protrusion 4 to move. When the rubber protrusion 4 is rotated to the side, it is also convenient to clean it, avoiding the problem of inconvenience in cleaning a large amount of debris attached to the surface of the rubber protrusion 4.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to further improve the driving stability of the ship in severe sea conditions, as Figure 6-Figure 7As shown, a bottom frame 6 is fixedly provided at the bottom of the hull 1, and two symmetrically distributed moving plates 8 are slidably provided in the bottom frame 6, and a second connecting mechanism 9 for connecting the rubber protrusion 4 is fixedly provided on the moving plate 8; a translation mechanism 7 for driving the two moving plates 8 to move simultaneously to drive the rubber protrusions 4 on both sides to extend outward is also provided in the bottom frame 6, and the translation mechanism 7 can be set as a screw mechanism. The two rubber protrusions 4 can extend outward to increase the area between the two rubber protrusions 4. When the ship encounters severe sea conditions such as big waves and strong currents during navigation, the extended rubber protrusions 4 can change the water flow pattern around the ship to increase the water resistance on the side of the ship, further improve the suppression effect on the roll and pitch of the ship, and the outwardly extended rubber protrusions 4 can make the ship perform better in different operating scenarios. For example, when performing water rescue tasks, the extended rubber protrusions 4 can be used as a temporary buffer device, which is convenient for approaching other distressed ships or objects to protect the safety of the distressed personnel and the ship itself.

[0034] The mounting portion 401 is also provided with a plurality of second strip-shaped through holes 404 for the second connecting mechanism 9 to pass through, which are distributed at equal intervals. The second strip-shaped through holes 404 and the first strip-shaped through holes 403 are distributed alternately.

[0035] The second connecting mechanism 9 includes a plurality of second rotating shafts 901 corresponding one to one with the second strip-shaped through holes 404, two second strip-shaped rods 902 are fixedly provided on the second rotating shaft 901, a second bearing seat 903 for supporting its rotation is provided at the end of the second rotating shaft 901, a second gear 904 is also fixedly sleeved on the second rotating shaft 901, a second rack 905 meshing with the second gear 904 is provided on the side of the second gear 904, a second electric push rod 906 for driving the movement is provided at the end of the second rack 905, and the second electric push rod 906 and the second bearing seat 903 are both fixed on the movable plate 8; the second strip-shaped rod 902 is rotated to a position perpendicular to the second strip-shaped through hole 404 to lock the second connecting mechanism 9 with the rubber protrusion 4, and the second strip-shaped rod 902 is rotated to a position overlapping with the second strip-shaped through hole 404 to release the locking state of the rubber protrusion 4 and the second connecting mechanism 9.

[0036] When the rubber protrusion 4 needs to be extended outward, the first strip rod 502 is first adjusted to a position that coincides with the first strip through hole 403 by the first electric push rod 506, and then the translation mechanism 7 drives the moving plate 8 to move, and the moving plate 8 drives the second connecting mechanism 9 to move, so that the second connecting mechanism 9 is inserted into the second strip through hole 404 until the two second strip rods 902 are respectively located on both sides of the rubber protrusion 4, and then the second rack 905 is driven to move by the second electric push rod 906, and the second rack 905 drives the second gear 9 04 rotates, the second gear 904 drives the second rotating shaft 901 to rotate, and the second rotating shaft 901 drives the second strip rod 902 to rotate. When the second strip rod 902 rotates to a vertical position with the second strip through hole 404, due to the obstruction of the second strip rod 902, the rubber protrusion 4 can be locked between the two second strip rods 902, and the moving plate 8 is continued to be driven to move by the translation mechanism 7, the moving plate 8 drives the second connecting mechanism 9 to move, and the second connecting mechanism 9 drives the rubber protrusion 4 to move, thereby realizing the rubber protrusion 4 extending outward.

[0037] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
