Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship design and construction, in particular to an inner hull design mechanism of a double-hull ship. Background Art
[0002] In the field of small vessels, such as yachts, speedboats and coastal operation vessels, although the sea conditions are relatively mild, sudden wind and waves and collision accidents still pose challenges to the safety performance of the vessels. Especially for small vessels with double-hull design, the inner hull, as a key part to protect the hull structure and ensure navigation safety, must have good impact resistance.
[0003] The inner and outer hulls of small ships are mostly connected by welding I-beams. Although hard materials such as I-beams can be used to connect them, when the outer shell is impacted, the hard materials will directly apply force to the inner hull, which can easily cause the inner hull to deform or even break. In addition, small ships are sensitive to weight, and an overly heavy inner hull design will increase the energy consumption and operating costs of the ship.
[0004] In view of this, an inner hull design mechanism for a double-hull ship is provided to overcome the above-mentioned defects. Utility Model Content
[0005] The utility model aims to provide an inner hull design mechanism for a double-hull ship to solve the problems raised in the above background technology.

The protective block includes a buffer block fixedly connected to the bottom of the bottom plate, a filling block filled inside the buffer block, and a welding block fixedly connected to the bottom of the buffer block.
[0007] Furthermore, the specific material of the buffer block is PE, the specific material of the filling block is foam, and the specific material of the welding block is iron.
[0008] Furthermore, a first mounting plate and a second mounting plate are fixedly mounted on the top surface of the storage plate, a sliding rod is fixedly mounted on the inner wall of the second mounting plate, and a rotatable bidirectional screw rod is also mounted on the side wall of the second mounting plate.

[0012] Furthermore, a resisting spring is fixedly connected between the square plate and the clamping plate.
[0013] Furthermore, a rotatable worm is mounted on one side of the first mounting plate, a worm wheel is fixedly connected to one side of the bidirectional lead screw, and the worm wheel and the worm are meshed with each other.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1
[0026] See also Figure 1-4 A double-hull ship inner hull design mechanism includes a storage plate 1, a hull head 2, a hull wall 3 and a bottom plate 4. A protective block 5 is fixedly installed on the bottom surface of the bottom plate 4, and a protective block 5 is also installed on the side wall of the hull wall 3. The protective blocks 5 are multiple in number. The multiple protective blocks 5 are distributed in a linear array on the bottom of the bottom plate 4 and the side wall of the hull wall 3. The protective block 5 includes a buffer block 52 fixedly connected to the bottom of the bottom plate 4, a filling block 53 filled inside the buffer block 52, and a welding block 51 fixedly connected to the bottom of the buffer block 52.
[0027] Furthermore, the specific material of the buffer block 52 is PE, the specific material of the filling block 53 is foam, and the specific material of the welding block 51 is iron. By setting the specific material of the welding block 51 to iron, it is convenient for the user to weld the outer shell of the double-hull ship through the welding block 51. By setting the material of the buffer block 52 to PE and the material of the filling block 53 to foam, the characteristics of PE with high toughness and strength are utilized to enhance the overall strength and rigidity of the hull, which helps the inner shell to resist external impact and pressure and reduce the risk of deformation and damage of the inner shell of the ship. The filling block 53 can further increase the strength and stability of the protective block 5. The closed structure formed after the foam filling helps to disperse and withstand the stress and pressure from various parts of the hull.
[0028] During specific implementation, the user needs to fix the protection block 5 on the side wall of the shell wall 3 and the bottom of the bottom plate 4, and weld the other end of the protection block 5 to the outer shell of the double-hull ship, so that the protection block 5 can be directly supported between the outer shell and the inner shell of the double-hull ship.
[0029] When the double-hull ship as a whole is subjected to external impact, the impact will directly act on the outer shell and then be transmitted to the protection block 5. When the impact force passes through the protection block 5, it will directly act on the buffer block 52 and the filling block 53. The material of the buffer block 52 is PE and the material of the filling block 53 is foam. Therefore, when the buffer block 52 is subjected to impact, the PE material can absorb most of the energy and release the remaining energy through its own elastic deformation, thereby effectively reducing the impact of the impact on the inner shell. At the same time, the filling block 53 formed after the foam filling can help the buffer block 52 to disperse and withstand the impact force, thereby further reducing the impact of the impact force on the inner shell. Under the simultaneous action of the two, when the double-hull ship is subjected to impact, its inner shell will not be easily damaged.
[0030] In addition, PE and foam are both light in weight, and when used in the protection block 5, they can reduce the overall weight of the double-hull ship, while increasing buoyancy, making the double-hull ship move more easily.
[0031] It should be noted that the multiple protection blocks 5 divide the bottom of the bottom plate 4 into multiple independent spaces, which prevents other parts of the hull from being easily affected when a part of the hull of the double-hull ship is broken and leaking, thereby increasing the safety of the hull operation.
[0032] By arranging a protective block 5 between the inner and outer shells of the double-hull ship, the structural strength and stability of the hull can be significantly improved, while the buoyancy can be enhanced, effectively resisting external impacts and the influence of severe sea conditions. The filling block 53 made of foam material also enhances the heat insulation and moisture-proof performance, and extends the service life of the hull.
[0033] Embodiment 2
[0034] Based on Example 1, please refer to Figure 1-4 , an inner hull design mechanism of a double-hull ship, wherein a first mounting plate 6 and a second mounting plate 7 are fixedly installed on the top surface of a storage plate 1, a sliding rod 8 is fixedly installed on the inner wall of the second mounting plate 7, and a rotatable storage plate 1 is also installed on the side wall of the second mounting plate 7, a movable plate 14 is threadedly connected to the outer wall of a two-way screw rod 13, and the movable plate 14 is slidably sleeved on the outer wall of the sliding rod 8, a square plate 9 is fixedly connected to one side of the movable plate 14, a telescopic rod 11 is fixedly installed on the inner wall of the square plate 9, and the other end of the telescopic rod 11 is fixedly connected to a clamping plate 10, a rotatable worm 15 is installed on one side of the first mounting plate 6, a worm wheel 16 is fixedly connected to one side of the two-way screw rod 13, and the worm wheel 16 and the worm 15 are meshed with each other.
[0035] Furthermore, the specific number of the movable plates 14 is two, and the two movable plates 14 are symmetrically arranged on the outer wall of the bidirectional screw rod 13 .
[0036] In addition, a resisting spring 12 is fixedly connected between the square plate 9 and the clamping plate 10 .
[0037] In specific implementation, after the user places the goods in the storage plate 1, the goods are easily affected by the shaking of the hull during the subsequent transportation process, and some ships use rigid limits to prevent the goods from being easily moved. However, such rigid limits can easily cause cargo loading containers such as tin cans and tin boxes to be directly damaged by the rigid limits.
[0038] In the present invention, the user can first place the goods between the two splints 10, and then turn the handle connected to one end of the worm 15 to make the worm 15 start to rotate. After the worm 15 rotates, it will drive the worm wheel 16 to rotate, and the worm wheel 16 is fixedly connected to the bidirectional screw 13, so the bidirectional screw 13 will also rotate synchronously. During the rotation of the bidirectional screw 13, the two movable plates 14 threadedly connected on the outer wall of the bidirectional screw 13 will move synchronously toward the middle, and a telescopic rod 11 is fixedly connected between the square plate 9 and the splint 10, and the square plate 9 is fixedly connected to the movable plate 14, so after the movable plate 14 moves, the splint 10 will also move synchronously.
[0039] When the two clamps 10 are close to the goods, the goods can be limited. A resisting spring 12 is fixedly connected between the clamps 10 and the square plate 9. Therefore, after the two clamps 10 clamp the goods, it will not cause excessive damage to the container carrying the goods.
[0040] By setting the splint 10 and the square plate 9, and setting the telescopic rod 11 and the resistance spring 12 between the splint 10 and the square plate 9, the goods can be limited by the two splints 10, so that the goods will not be easily displaced during the movement. The existence of the resistance spring 12 and the telescopic rod 11 ensures that the splint 10 will not cause excessive damage to the container carrying the goods, thereby increasing the stability of cargo transportation.
[0041] Working principle: The user needs to fix the protection block 5 on the side wall of the shell wall 3 and the bottom of the bottom plate 4, and weld the other end of the protection block 5 to the outer shell of the double-hull ship, so that the protection block 5 can be directly supported between the outer shell and the inner shell of the double-hull ship.
[0042] When the double-hull ship as a whole is subjected to external impact, the impact will directly act on the outer shell and then be transmitted to the protection block 5. When the impact force passes through the protection block 5, it will directly act on the buffer block 52 and the filling block 53. The material of the buffer block 52 is PE and the material of the filling block 53 is foam. Therefore, when the buffer block 52 is subjected to impact, the PE material can absorb most of the energy and release the remaining energy through its own elastic deformation, thereby effectively reducing the impact of the impact on the inner shell. At the same time, the filling block 53 formed after the foam filling can help the buffer block 52 to disperse and withstand the impact force, thereby further reducing the impact of the impact force on the inner shell. Under the simultaneous action of the two, when the double-hull ship is subjected to impact, its inner shell will not be easily damaged.
[0043] In addition, PE and foam are both light in weight, and when used in the protection block 5, they can reduce the overall weight of the double-hull ship, while increasing buoyancy, making the double-hull ship move more easily.
[0044] It should be noted that the multiple protection blocks 5 divide the bottom of the bottom plate 4 into multiple independent spaces, which prevents other parts of the hull from being easily affected when a part of the hull of the double-hull ship is broken and leaking, thereby increasing the safety of the hull operation.
[0045] After the user places the goods in the storage plate 1, the goods are easily affected by the shaking of the hull during the subsequent transportation process. Some ships use rigid limits to prevent the goods from being easily moved. However, such rigid limits can easily cause cargo loading containers such as tin cans and tin boxes to be directly damaged by the rigid limits.
[0046] In the present invention, the user can first place the goods between the two splints 10, and then turn the handle connected to one end of the worm 15 to make the worm 15 start to rotate. After the worm 15 rotates, it will drive the worm wheel 16 to rotate, and the worm wheel 16 is fixedly connected to the bidirectional screw 13, so the bidirectional screw 13 will also rotate synchronously. During the rotation of the bidirectional screw 13, the two movable plates 14 threadedly connected on the outer wall of the bidirectional screw 13 will move synchronously toward the middle, and a telescopic rod 11 is fixedly connected between the square plate 9 and the splint 10, and the square plate 9 is fixedly connected to the movable plate 14, so after the movable plate 14 moves, the splint 10 will also move synchronously.
[0047] When the two clamps 10 are close to the goods, the goods can be limited. A resisting spring 12 is fixedly connected between the clamps 10 and the square plate 9. Therefore, after the two clamps 10 clamp the goods, it will not cause excessive damage to the container carrying the goods.
[0048] By arranging a protective block 5 between the inner and outer shells of the double-hull ship, the structural strength and stability of the hull can be significantly improved, while the buoyancy can be enhanced, effectively resisting external impacts and the influence of severe sea conditions. The filling block 53 made of foam material also enhances the heat insulation and moisture-proof performance, and extends the service life of the hull.
[0049] By setting the splint 10 and the square plate 9, and setting the telescopic rod 11 and the resistance spring 12 between the splint 10 and the square plate 9, the goods can be limited by the two splints 10, so that the goods will not be easily displaced during the movement. The existence of the resistance spring 12 and the telescopic rod 11 ensures that the splint 10 will not cause excessive damage to the container carrying the goods, thereby increasing the stability of cargo transportation.
