Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and in particular relates to a roll-reducing vessel. Background Technology

[0002] Ships face a dual challenge in terms of maneuverability and energy efficiency under complex sea conditions: on the one hand, severe rolling caused by adverse sea conditions not only affects navigation safety, cargo stability, and passenger comfort, but also exacerbates the risk of hull structural fatigue; on the other hand, traditional roll reduction technologies (such as stabilizing fins and roll-damping tanks) suffer from high energy consumption, slow response speed, and insufficient dynamic adaptability, making it difficult to meet the needs of intelligent shipping. Traditional roll reduction technologies are mainly mechanical: roll-damping fins generate reaction torque through hydrodynamics, but are limited by speed and require continuous power consumption; roll-damping tanks rely on liquid flow to adjust the center of gravity, resulting in large size, delayed response, and potential roll increase risks.

[0003] Meanwhile, the ship's automatic steering system is highly dependent on external power supply and is prone to control failure under energy fluctuations or extreme sea conditions. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a roll-damping vessel that is suitable for complex sea conditions, has high stability, and is self-powered.

[0005] Technical solution: The present invention discloses a roll-damping boat, comprising a piezoelectric hydrofoil assembly disposed on the outside of the hull and capable of converting water kinetic energy into electrical energy, and a hydrofoil angle-of-attack adjustment assembly installed inside the hull with its movable part extending to the outside of the hull and connected to the piezoelectric hydrofoil assembly for adjusting the angle of the piezoelectric hydrofoil assembly; the piezoelectric hydrofoil assembly comprises an epoxy resin insulating layer, piezoelectric ceramic layers attached to both sides of the epoxy resin insulating layer, and a waterproof sealing layer wrapped around the epoxy resin insulating layer and the piezoelectric ceramic layers.

[0006] Furthermore, the hydrofoil angle of attack adjustment assembly includes a first support frame disposed inside the hull, a first cylinder fixedly connected to the first support frame, a toothed plate fixedly connected to the movable end of the first cylinder, a gear meshing with the toothed plate, a drive shaft fixedly connected to the central shaft of the gear, and a second support frame fixedly disposed inside the hull to support the drive shaft. The drive shaft is rotatably connected to the second support frame, and the other end of the drive shaft passes through the second support frame and is fixedly connected to the piezoelectric hydrofoil assembly.

[0007] Furthermore, an angle sensor for detecting the angle of the piezoelectric hydrofoil assembly is fixedly connected to the drive shaft.

[0008] Furthermore, the hydrofoil angle of attack adjustment assembly also includes a housing fixedly connected to the second support frame and located between the second support frame and the gear, a third support frame fixedly connected to the top of the housing, and a roller rotatably connected to the third support frame. The bottom of the roller extends into and is movably connected to a limiting groove opened at the top of the gear plate. The housing is fitted around the outer periphery of the drive shaft.

[0009] Furthermore, the hydrofoil angle of attack adjustment assembly also includes multiple supports that gradually rise from the outside of the hull to the inside of the hull and are fixedly connected to the inside of the hull, as well as a support platform that is inclined and fixedly connected to the top of the multiple supports. The first support frame and the second support frame are both fixedly connected to the support platform.

[0010] Furthermore, the piezoelectric hydrofoil assembly also includes a fixed rod fixedly disposed on one side of the epoxy resin insulating layer and the piezoelectric ceramic layer, and a connecting rod connected to the other end of the fixed rod via a universal joint connecting shaft. The other end of the connecting rod extends into the hull and is fixedly connected to the drive shaft.

[0011] Furthermore, a waterproof sealing plug is fixedly connected to the outer periphery of the connecting rod.

[0012] Furthermore, it also includes a storage component installed on one side of the piezoelectric hydrofoil assembly for storing and deploying the piezoelectric hydrofoil assembly.

[0013] Furthermore, the storage assembly includes a second cylinder movably connected to a fixed rod via a ball connector and a fourth support frame fixedly connected inside the hull, with the fixed end of the second cylinder fixedly connected to the fourth support frame.

[0014] Furthermore, another waterproof sealing plug is fixedly connected to the outer periphery of the second cylinder.

[0015] Beneficial Effects: Compared with existing technologies, this invention has the following advantages: This invention uses a hydrofoil made of piezoelectric material. On the one hand, the lift generated by the hydrofoil reduces roll and improves the stability of the ship during navigation. On the other hand, during navigation, the mechanical deformation of the piezoelectric material due to the kinetic energy of the water flow can be converted into electrical energy to power the ship. Furthermore, the hydrofoil angle-of-attack adjustment component can actively adjust the angle of attack of the piezoelectric hydrofoil assembly to adapt to different sea conditions, ensuring stable navigation.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0025] This utility model discloses a type of anti-rolling boat, such as... Figure 1 As shown, the system includes a piezoelectric hydrofoil assembly, a hydrofoil angle-of-attack adjustment assembly, and a storage assembly. The piezoelectric hydrofoil assembly is located outside the hull. On one hand, it converts the kinetic energy of water into electrical energy, which can be used by the ship. On the other hand, the lift generated by the piezoelectric hydrofoil assembly can reduce the ship's rolling motion, thereby improving the ship's stability during navigation. The hydrofoil angle-of-attack adjustment assembly is installed inside the hull, with its movable part extending outside the hull to connect with the piezoelectric hydrofoil assembly. It is used to adjust the angle of the piezoelectric hydrofoil assembly according to actual needs, so that the anti-roll boat can be adapted to different complex sea conditions. The storage assembly is installed on one side of the piezoelectric hydrofoil assembly for storing and deploying the piezoelectric hydrofoil assembly. When the anti-roll boat does not need to use the piezoelectric hydrofoil assembly, it can be folded into place on the outside of the ship through the storage assembly. When the piezoelectric hydrofoil assembly is not needed, it can be deployed through the storage assembly for anti-roll purposes.

[0026] like Figures 1-4As shown, the piezoelectric hydrofoil assembly includes an epoxy resin insulating layer 1, a piezoelectric ceramic layer 2, a waterproof sealing layer 3, a fixing rod 15, a universal joint connecting shaft 16, and a connecting rod 17. Piezoelectric ceramic layers 2 are attached to both sides of the epoxy resin insulating layer 1, and the polarization directions of the piezoelectric ceramic layers 2 on both sides of the epoxy resin insulating layer 1 are opposite. The waterproof sealing layer 3 wraps around the outer periphery of the epoxy resin insulating layer 1 and the piezoelectric ceramic layer 2. The fixing rod 15 is fixedly connected to one side of the epoxy resin insulating layer 1 and the piezoelectric ceramic layer 2. The connecting rod 17 is connected to the other end of the fixing rod 15 through the universal joint connecting shaft 16, and the other end of the connecting rod 17 extends into the hull and is fixedly connected to the drive shaft 7. A through hole is provided on the hull for the connecting rod 17 to pass through, and a waterproof sealing plug 18 matching the through hole is fixedly connected to the outer periphery of the connecting rod 17 to prevent seawater from entering the hull. In actual use, the wires led out from the piezoelectric ceramic layer 2 can be sealed with waterproof sealing plug 18 to prevent seawater penetration. The wires of the piezoelectric ceramic layer 2 are connected to the rectifier of the hull through armored waterproof cable. The output end of the rectifier is connected to the ship's supercapacitor / battery pack to ensure stable storage of generated electrical energy. The piezoelectric ceramic layer 2 undergoes mechanical deformation under the action of fluid force and converts mechanical energy into electrical energy, which is then stored in the ship's supercapacitor / battery pack.

[0027] like Figure 1 , Figures 5-8As shown, the hydrofoil angle-of-attack adjustment assembly includes a bracket 13, a support platform 14, a first support frame 4, a first cylinder 5, a gear plate 6, a gear 22, a drive shaft 7, a second support frame 8, a housing 11, a third support frame 10, and rollers 12. Multiple brackets 13 are provided, each fixedly connected to the interior of the hull, with the height of the brackets gradually increasing from the exterior to the interior of the hull. The support platform 14 is inclined and fixedly connected to the multiple brackets 13. The first support frame 4 and the second support frame 8 are both fixedly connected to the support platform 14. The fixed end of the first cylinder 5 is fixedly connected to the first support frame 4, and the movable end of the first cylinder 5 is fixedly connected to the gear plate 6. The gear 22 meshes with the gear plate 6. The drive shaft 7 is fixedly connected to the central axis of the gear 22, and the drive shaft 7 is rotatably connected to the second support frame 8. The end of the transmission shaft 7 passes through the second support frame 8 and is fixedly connected to the piezoelectric hydrofoil assembly. The support platform 14 has a groove that matches the gear 22 to facilitate the rotation of the gear 22. The end of the transmission shaft 7 away from the gear 22 is fixedly connected to the connecting rod 17, and an angle sensor 9 for detecting the angle of the piezoelectric hydrofoil assembly is fixedly connected to the transmission shaft 7. The housing 11 is fixedly connected to the second support frame 8 and is located between the second support frame 8 and the gear 22. The third support frame 10 is fixedly connected to the top of the housing 11, and the housing 11 is fitted around the outer periphery of the transmission shaft 7. The roller 12 is rotatably connected to the housing 11, and the roller 12 is located directly above the toothed plate 6. The top of the toothed plate 6 has a limiting groove, and the bottom of the roller 12 extends into the limiting groove and is movably connected to it. The setting of the limiting groove of the roller 12 and the toothed plate 6 can improve the stability of the toothed plate 6 when it moves back and forth. When the angle of attack of the piezoelectric hydrofoil assembly needs to be adjusted, the first cylinder 5 is extended or retracted, driving the gear plate 6 to reciprocate. The movement of gear 6 drives gear 22 to rotate, which in turn drives the transmission shaft 7 to rotate synchronously. This causes the synchronous shaft 7 to rotate the piezoelectric hydrofoil assembly, adjusting its angle. The angle sensor 9 rotates synchronously with the transmission shaft 7 and the piezoelectric hydrofoil assembly, facilitating the detection of the angle of attack of the piezoelectric hydrofoil assembly. In actual use, a control panel 23 electrically connected to the first cylinder 5, angle sensor 9, and second cylinder 19 can be installed on the side of the first support frame 4 for convenient control of the first cylinder 5 and second cylinder 19. A lubricating oil tank 24 connected to the first cylinder 5, second cylinder 19, gear 22, etc., can be installed on the bracket 13 to reduce transmission friction loss. The lubricating oil tank 24 can be checked periodically during use.

[0028] like Figure 1 and Figure 4As shown, the storage assembly includes a ball connector 21, a second cylinder 19, and a fourth support frame 20. The fourth support frame 20 is fixedly installed on the support platform 14. The fixed end of the second cylinder 19 is fixedly connected to the support platform 14, and the movable end of the second cylinder 19 is movably connected to the fixed rod 15 through the ball connector 21. A through hole is provided on the hull for the second cylinder 19 to pass through, and a waterproof sealing plug 18 is fixedly connected to the outer periphery of the second cylinder 19. The waterproof sealing plug 18 can prevent seawater from entering the interior of the hull through the through hole. When the piezoelectric hydrofoil assembly is not needed, the angle of the piezoelectric hydrofoil assembly is first adjusted by the first cylinder 5, so that the wing plate part composed of epoxy resin insulation layer 1, piezoelectric ceramic layer 2 and waterproof sealing layer 3 rotates to a suitable angle. Then, the second cylinder 19 is controlled to retract, so that the fixing rod 15 folds relative to the connecting rod 17 until the wing plate part composed of epoxy resin insulation layer 1, piezoelectric ceramic layer 2 and waterproof sealing layer 3 is attached to the outside of the hull. The inclined setting of the support platform 14 allows the wing plate part to better fit with the inclined outside of the hull. When the piezoelectric hydrofoil assembly is needed to reduce roll, the second cylinder 19 is controlled to extend, so that the wing plate part composed of epoxy resin insulation layer 1, piezoelectric ceramic layer 2 and waterproof sealing layer 3 unfolds. The wing plate part suppresses the roll of the hull and improves the stability of the hull during navigation.

[0029] When the piezoelectric hydrofoil assembly is needed to reduce roll, the second cylinder 19 is extended, causing the wing plate portion, composed of the epoxy resin insulation layer 1, the piezoelectric ceramic layer 2, and the waterproof sealing layer 3, to unfold. This wing plate portion suppresses hull roll and improves the ship's stability during navigation. During navigation, the angle of attack of the piezoelectric hydrofoil assembly is adjusted according to the actual sea conditions. The first cylinder 5 is extended or retracted, driving the gear plate 6 to reciprocate. The movement of gear 6 drives gear 22 to rotate, which in turn drives the transmission shaft 7 to rotate synchronously. This, in turn, causes the synchronous shaft 7 to rotate the piezoelectric hydrofoil assembly, adjusting its angle. The angle sensor 9 and the transmission shaft 7 then rotate. The rotating shaft 7 and the piezoelectric hydrofoil assembly rotate synchronously, facilitating the detection of the angle of attack of the piezoelectric hydrofoil assembly. When the piezoelectric hydrofoil assembly is not needed, the angle of the piezoelectric hydrofoil assembly is first adjusted by the first cylinder 5, so that the wing plate part composed of epoxy resin insulation layer 1, piezoelectric ceramic layer 2 and waterproof sealing layer 3 rotates to a suitable angle. Then, the second cylinder 19 is controlled to retract, so that the fixing rod 15 folds relative to the connecting rod 17 until the wing plate part composed of epoxy resin insulation layer 1, piezoelectric ceramic layer 2 and waterproof sealing layer 3 is attached to the outside of the hull. The inclined setting of the support platform 14 allows the wing plate part to better fit with the outside of the hull.
