Description

Technical Field

[0001] The invention relates to the field of marine engineering technology, specifically to a marine airfoil sail combined synchronous control device and control method. Background Technology

[0002] Airfoil sails are modern sail-assisted navigation devices based on aerodynamic principles. Their cross-sectional shape resembles an aircraft wing, generating lift to provide auxiliary thrust for ships, thereby effectively reducing fuel consumption and emissions. As a core solution in current wind-powered navigation technology, its revival and development are primarily driven by the energy crisis, increasingly stringent environmental regulations, and advancements in aerodynamic theory.

[0003] In existing technologies, marine airfoil sails mainly take two forms: single sail or multiple sails in independent combination. Single sails have a simple structure but limited propulsion efficiency and are mainly used on small vessels. While multiple sail combinations can increase total thrust, the independent operation systems of each sail on the vessel rely on a main control device for coordinated control. When encountering storms at sea, various problems such as data distortion and local malfunctions can occur, leading to asynchronous operation of the sails and affecting propulsion stability. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the invention provides a marine airfoil sail combined synchronous control device and control method, which solves the problems mentioned in the background above.

[0005] The invention provides the following technical solution: a marine airfoil sail combined synchronous control device, comprising multiple sets of sail components installed on the ship's deck for navigation assistance; Multiple sets of the sail assemblies are equipped with chain components on top for integrating multiple sets of the sail assemblies into the same control system. The bottom of each set of the sail assemblies is mounted on the deck via a base, and a manual control component is fitted on the bottom of the sail assembly. The sail assembly includes a sail body for utilizing wind power, and control connection components are integrally provided at the upper and lower ends of the sail body. The control connection components located at the upper and lower ends of the sail body are coaxially arranged at the center line, and the top and bottom of the sail body cooperate with the chain component and the independent control component through the provided control connection components. The chain assembly includes a coaxially connected sail assembly and a shaft control assembly rotatably mounted in the base. A sprocket is fitted onto a section of the shaft control assembly protruding from the top of the sail assembly, and a chain for driving with adjacent sail assemblies is provided on the sprocket.

[0006] Preferably, the control connection component includes a sail column integrally disposed at both the upper and lower ends of the sail body. The sail column is fitted with a push-connection component for engaging with the sail body and the chain component and / or the independent control component, and a keyway is formed on the sail column near the sail body to guide the movement direction of the push-connection component.

[0007] Preferably, the sail body has receiving cavities at the base of the sail column at both ends, and the push-connecting assembly is slidably inserted into the receiving cavity at the end near the sail body.

[0008] Preferably, the control assembly includes a spline sleeve slidably fitted on the control assembly. The end of the spline sleeve away from the sail body has a clutch end for engaging with a chain assembly and / or an independent control assembly. A stepped groove is recessed on the outer peripheral wall of the spline sleeve, and a push sleeve is fitted on the groove. The piston rod of a hydraulic cylinder housed in the receiving cavity is mounted on a push frame integrally formed on the side of the push sleeve. The end of the push sleeve away from the hydraulic cylinder overlaps with a spring fitted on the groove.

[0009] Preferably, the end of the sail column located at the bottom of the sail body is inserted into the base from top to bottom to form a disc-shaped base, and the sail column at the bottom of the sail body is rotatably mounted in the base through a yaw bearing provided on the base.

[0010] Preferably, both the upper and lower ends of the sail are provided with protective shells for accommodating the control assembly, and the sail rotates with the chain assembly and the independent control assembly through mechanical seals provided in the protective shells.

[0011] Preferably, the shaft control assembly includes a main control shaft that coaxially penetrates the sail assembly from bottom to top, and the outer peripheral wall of the main control shaft is rotatably connected to the sail assembly through a bearing. The bottom end of the main control shaft is inserted into the base and forms a disc-shaped base, and is rotatably connected to the interior of the base through a first slewing bearing provided on the base. A worm gear component for connecting a drive device is formed on the outer peripheral wall of the first slewing bearing.

[0012] Preferably, the top of the main control shaft protrudes from the sail assembly and is integrally provided with a top connection end, the sprocket is sleeved on the top connection end, and the bottom end of the top connection end is formed with a toothed opening for engaging with the control connection assembly.

[0013] Preferably, the independent control component includes a connecting control cylinder rotatably sleeved on the control connection component at the bottom of the sail. The top end of the connecting control cylinder has a meshing end for engaging with the control connection component. The bottom end of the connecting control cylinder has a disc-shaped base, which is rotatably mounted on the base via a second slewing bearing. A worm gear for connecting an external control device is formed on the outer peripheral wall of the second slewing bearing.

[0014] A method for synchronous control of a marine airfoil sail combination includes the following steps: S1. Before the ship sets sail, check the condition of each component in the airfoil sail to ensure that all components are in good condition. S2, control the connection component on the sail to connect with the independent control component. After the connection is completed, disconnect the connection component on the sail from the chain component, so that each set of sail components becomes an independent unit. The angle of each set of sail components is finely adjusted so that multiple sets of sail components reach a parallel state. Then reconnect the connection component on the sail to the chain component and control it to disconnect from the independent control component. S3, Before setting sail, rotate the sail to the angle of minimum lateral force, and calculate the sail rotation angle θ based on the real-time monitored relative wind angle α: If α is [0°, 180°], then θ = α - 90° If α is [180°, 360°], then θ = α - 270°; S4, during the ship's departure, the angle of the airfoil is controlled by the drive equipment. At this time, the chain assembly is rotated by the drive equipment and drives the airfoil assembly to rotate synchronously by using the docking state between the top and the airfoil assembly. The average wind direction in the 10 minutes before the airfoil rotates is used as a parameter to adjust the airfoil to the angle that can provide the maximum thrust. S5, when one group of airfoil sails, which is the main control component, rotates, the other groups of airfoil sails are controlled by chain connection and begin to rotate synchronously, so as to realize the synchronous control of multiple groups of airfoil sails with a single transmission system.

[0015] Compared with existing technologies, the invention has the following beneficial effects: 1. The shipborne airfoil sail combined synchronous control device and control method uses a shaft control component that runs through the middle of the sail assembly as the drive core. The shaft control component in one set of sail assemblies is controlled by a drive device, and a chain structure is formed at the top that is linked with the adjacent airfoil sails. This integrates multiple airfoil sails on the ship into the same chain transmission frame, achieving a mechanical synchronous control effect. This can save energy generated by multiple control units, reduce the impact of storms and magnetic fields on the multi-core control system, ensure the synchronous operation of each sail, and improve the stability of propulsion.

[0016] 2. The ship's airfoil sail combined synchronous control device and control method, by setting control connection components on the sail components, when the angle of some sail components is misaligned, can use the clutch operation of the control connection components to disconnect one of the sail components from the chain drive frame, and then perform independent control through the docking of the independent control components to complete the fine adjustment operation. At the same time, it can also turn all sail components into independent sails with multi-core control to meet specific navigation requirements. Attached Figure Description

[0019] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0020] For details, please refer to Figure 1 and Figure 2 Marine airfoil sail combined synchronous control device, including multiple sets of sail components 1 installed on the ship deck for navigation aid; Multiple sets of sail components 1 are equipped with chain components 2 on top, which are used to integrate multiple sets of sail components 1 into the same control system. The bottom of each set of sail components 1 is mounted on the deck through a base 4, and a manual control component 3 is fitted on the bottom of the sail components 1.

[0021] In one embodiment, the sail assembly 1, the chain assembly 2, and the independent control assembly 3 each have a component directly connected to the bottom, and the three components are coaxially fitted with the component connected to the bottom, and a layered base 4 is provided at the bottom to connect to the deck; in other embodiments, they can also be directly installed in the ship through the deck, without the need to form an outward protruding part like the base 4 on the deck, and the effect of this embodiment can be achieved in both cases.

[0022] For details, please refer to Figure 1-3 The sail assembly 1 includes a sail body 11 for using wind power, and control connection components 12 are integrally provided at the upper and lower ends of the sail body 11. The control connection components 12 located at the upper and lower ends of the sail body 11 are coaxially arranged at the center line, and the top and bottom of the sail body 11 are connected to the chain assembly 2 and the independent control assembly 3 through the provided control connection components 12.

[0023] In one embodiment, control connection components 12 are provided at both ends of the sail 11 to cooperate with the chain component 2 and the independent control component 3 to form two clutches. By selectively driving the connection state of the control connection components 12, they can cooperate with the chain component 2 or the independent control component 3 respectively, thereby achieving the effect of switching control modes.

[0024] Please refer to Figure 6 The control assembly 12 includes a sail column 121 integrally disposed at the upper and lower ends of the sail body 11. A push-connection assembly 122 is sleeved on the sail column 121 for engaging with the sail body 11 and the chain assembly 2 and / or the independent control assembly 3. A keyway is formed on the sail column 121 near the sail body 11 to guide the movement direction of the push-connection assembly 122.

[0025] In this embodiment, the keyway on the sail column 121 cooperates with the push-connecting assembly 122, so that the push-connecting assembly 122 can only slide parallel to the direction of the sail column 121. After the push-connecting assembly 122 is connected to the chain assembly 2 or the independent control assembly 3, the meshing teeth of the connection cooperate with the meshing limit state of the keyway and the push-connecting assembly 122 to drive the sail body 11 to rotate.

[0026] Please refer to Figure 6 and Figure 7 The sail body 11 has receiving cavities 13 at both ends of the sail column 121 at the root, and the push-connecting assembly 122 is slidably inserted into the receiving cavity 13 at the end near the sail body 11.

[0027] In this embodiment, the sail 11 adopts a lightweight design, with a hollowed-out interior and an independent receiving cavity 13 for the control assembly 12, so that the movable components can be hidden away, reducing the impact of the external environment on the moving parts of the sail 11.

[0028] Please refer to Figure 8The control assembly 12 includes a spline sleeve 1221 slidably sleeved on the control assembly 12. The end of the spline sleeve 1221 away from the sail body 11 forms a clutch end 1222 for engaging with the chain assembly 2 and / or the independent control assembly 3. A stepped groove 1223 is recessed on the outer peripheral wall of the spline sleeve 1221, and a push sleeve 1224 is sleeved on the groove 1223. The piston rod of a hydraulic cylinder 1227 housed in the receiving cavity 13 is mounted with a push frame 1226 integrally formed on the side of the push sleeve 1224. The end of the push sleeve 1224 away from the hydraulic cylinder 1227 overlaps with a spring 1225 sleeved on the groove 1223.

[0029] In this embodiment, the position of the push sleeve 1224 is controlled by the extension and retraction of the piston rod of the hydraulic cylinder 1227, so that the clutch end 1222 is pressed against the chain assembly 2 or the independent control assembly 3 under the push of the spring 1225. Furthermore, the elastic force of the spring 1225 provides a certain degree of flexible compensation during engagement. Even if the engagement is not fully completed, it can be misaligned as the chain assembly 2 or the independent control assembly 3 is activated, triggering the flexible compensation effect to complete the engagement.

[0030] Please refer to Figure 6 The end of the sail post 121 located at the bottom of the sail body 11 is inserted into the base 4 from top to bottom to form a disc-shaped base. The sail post 121 at the bottom of the sail body 11 is rotatably mounted in the base 4 through the yaw bearing 14 provided on the base.

[0031] In this embodiment, the sail column 121 at the bottom of the sail 11 rotates with the base 4, so that the weight of the sail 11 is separated from the chain assembly 2 and the independent control assembly 3 and is transferred to the base 4 respectively, thereby ensuring the stability of the connection between the sail assembly 1, the chain assembly 2 and the independent control assembly 3, and avoiding deformation due to excessive force on a single component.

[0032] Please refer to Figure 1 and Figure 2 Both the upper and lower ends of the sail 11 are provided with protective shells for accommodating the control assembly 12, and the sail rotates with the chain assembly 2 and the independent control assembly 3 through the mechanical seals provided in the protective shells.

[0033] In this embodiment, the moving parts of both the sail assembly 1 and the chain assembly 2 are encased in a shell structure, and mechanical seals are used in the moving parts to allow the moving parts of the airfoil sail to be filled with lubricant inside the shell structure, ensuring smooth operation after startup and reducing corrosion caused by the external environment.

[0034] For details, please refer to Figure 2 and Figure 4The chain assembly 2 includes a shaft control assembly 21 that is coaxially connected to the sail assembly 1 and rotatably disposed in the base 4. A sprocket 22 is sleeved on a section of the shaft control assembly 21 that protrudes from the top of the sail assembly 1, and a chain 23 for transmission with the adjacent sail assembly 1 is provided on the sprocket 22.

[0035] In one embodiment, the adjacent airfoil sails are integrated by using the chain 23. Only one shaft control component 21 is needed as the main control component to drive all the sail components 1 in the same chain drive frame, achieving a mechanical linkage effect and ensuring synchronous control of multiple sets of sail components 1.

[0036] Please refer to Figure 4 The axis control assembly 21 includes a main control shaft 211 that coaxially penetrates the sail assembly 1 from bottom to top. The main control shaft 211 is rotatably connected to the sail assembly 1 through a bearing on its outer peripheral wall. The bottom end of the main control shaft 211 is inserted into the base 4 and forms a disc-shaped base. It is rotatably connected to the interior of the base 4 through a first slewing bearing 213 provided on the base. A worm gear member for connecting a drive device is formed on the outer peripheral wall of the first slewing bearing 213.

[0037] In this embodiment, only one first slewing bearing 213 with a worm gear component exists in the shaft control assembly 21 within the same chain drive frame. Other shaft control assemblies 21 that serve as secondary control components each have only one bearing for supporting the base. This ensures that the other secondary control components can only be driven by the primary control component. At the same time, the worm gear component is used in conjunction with the first slewing bearing 213 for driving, which creates an automatic locking part in the first slewing bearing 213, thereby improving the wind torque resistance of the airfoil sail.

[0038] Please refer to Figure 4 The top of the main control shaft 211 protrudes from the sail assembly 1 and is integrally provided with a top connection end 212. The sprocket 22 is sleeved on the top connection end 212, and the bottom end of the top connection end 212 has a toothed opening for engaging with the control connection assembly 12.

[0039] In this embodiment, each of the main control shafts 211 in the multiple airfoil sails has a top connection end 212, so that the control connection component 12 of each airfoil sail can selectively connect with the top connection end 212. This allows a single airfoil sail to be detached from the same chain drive frame, improving the flexibility of airfoil sail use.

[0040] Please refer to Figure 5The independent control component 3 includes a control cylinder 31 rotatably mounted on the control connection component 12 at the bottom of the sail 11. The top end of the control cylinder 31 has a meshing end 32 for engaging with the control connection component 12. The bottom end of the control cylinder 31 has a disc-shaped base and is rotatably mounted on the base 4 via a second rotary bearing 33 provided on the base. A worm gear for connecting an external control device is formed on the outer peripheral wall of the second rotary bearing 33.

[0041] In this embodiment, the independent control component 3 uses the engagement end 32 to connect with the control connection component 12, so that the airfoil sails that are detached from the same set of chain drive frames can be linked with the control equipment through the second slewing bearing 33 at the bottom to form an independent control unit, thereby switching multiple sets of airfoil sails from synchronous control to single-set drive to deal with special situations.

[0042] A method for synchronous control of a marine airfoil sail combination includes the following steps: S1. Before the ship sets sail, check the condition of each component in the airfoil sail to ensure that all components are in good condition. S2, control the connection component 12 on the sail 11 to connect with the independent control component 3. After the connection is completed, disconnect the connection component 12 on the sail 11 from the chain component 2, so that each set of sail components 1 becomes an independent unit. The angle of each set of sail components 1 is finely adjusted so that multiple sets of sail components 1 reach a parallel state. Then reconnect the connection component 12 on the sail 11 to the chain component 2 and control it to disconnect from the independent control component 3. S3, Before setting sail, rotate the sail to the angle of minimum lateral force, and calculate the sail rotation angle θ based on the real-time monitored relative wind angle α: If α is [0°, 180°], then θ = α - 90° If α is [180°, 360°], then θ = α - 270°; S4, during the ship's departure, the angle of the airfoil sail is controlled by the drive equipment. At this time, the chain assembly 2 is rotated by the drive equipment and drives the sail assembly 1 to rotate synchronously by using the docking state of the top. The average wind direction in the 10 minutes before the airfoil sail rotates is used as a parameter to adjust the airfoil sail to the angle that can provide the maximum thrust. S5, when one group of airfoil sails, which is the main control component, rotates, the other groups of airfoil sails are connected and controlled by chain 23 and begin to rotate synchronously, so as to realize the synchronous control of multiple groups of airfoil sails with a single transmission system.
