[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] To address the aforementioned technical problems, this invention provides a sail device and a vessel that not only facilitates the rapid raising and lowering of sails, saving time and effort and greatly improving the convenience of raising and lowering sails, but also reduces the risks to the vessel caused by untimely raising and lowering of sails, thereby improving the safety of the vessel's navigation.

[0019] Please see Figure 1-2 This invention provides a sail device, which includes a fixed base 1, multiple sub-sail assemblies 2, and an opening and closing drive assembly 3. The multiple sub-sail assemblies 2 are respectively arranged on the periphery of the fixed base 1. Each sub-sail assembly 2 is provided with a split sail surface 6 (not shown in the figure), and each sub-sail assembly 2 is openable and closable. The opening and closing drive assembly 3 is connected to each sub-sail assembly 2 in a transmission connection.

[0020] In practical applications, the aforementioned fixed base 1 can be fixedly installed on the mast of a ship, and the opening and closing drive assembly 3 can drive each sub-sail assembly 2 to automatically open or close, so as to realize the raising and lowering of the sails.

[0021] In this embodiment, the multiple sub-sail components 2 can be circumferentially distributed around the fixed base 1. When all the multiple sub-sail components 2 are fully deployed, the separate sail surfaces 6 on each sub-sail component 2 can be spliced ​​together to form a complete sail surface.

[0022] It should be noted that the number of the sub-sail components 2 can be set as needed, for example, it can be 3, 4, 5, 6 or more, and there is no specific limit to this.

[0023] In one embodiment, please refer to Figure 1-2 The number of sub-sail assemblies 2 can be set to 6, with 6 sub-sail assemblies 2 arranged around the periphery of the fixed base 1.

[0024] Taking one of the sub-sail components, 2, as an example, Figure 3 As shown, the subsail assembly 2 includes a support 21 and multiple linkage units 22. The multiple linkage units 22 are disposed on the support 21 and connected to each other so that the subsail assembly 2 can form a honeycomb mesh structure.

[0025] Specifically, such as Figure 4As shown, the support 21 includes a longitudinal support 211 and a transverse support 212. The longitudinal support 211 can be arranged longitudinally on the outside of the fixed base 1, while the transverse support 212 can be transversely fixedly arranged on the longitudinal support 211 near the opening and closing drive assembly 3. Both the longitudinal support 211 and the transverse support 212 are provided with slide rails.

[0026] Based on this, the aforementioned multiple linkage units 22 are arranged on the bearing support 21. Taking any one of the linkage units 22 as an example, the linkage unit 22 includes two links, the middle of the two links are hinged to each other, and its four ends (each link has two ends) can be connected to other linkage units 22 respectively.

[0027] In order to set each link unit 22 on the above-mentioned bearing support 21, the above-mentioned multiple link units 22 can also be divided into multiple main link units 221 and multiple secondary link units 222 according to their respective configuration.

[0028] Multiple main connecting rod units 221 can be arranged longitudinally on the aforementioned longitudinal support 211, and can be slidably connected to the longitudinal support 211 via slide rails on the longitudinal support 211. The number of these units can be determined according to the required sail area, and no specific limitation is required.

[0029] In one embodiment, please refer to Figure 3 The aforementioned main linkage unit 221 can be configured as five units, which can be distributed longitudinally on the longitudinal support 211. For ease of explanation, the five main linkage units 221 can be sequentially referred to as the first main linkage unit, the second main linkage unit, the third main linkage unit, the fourth main linkage unit, and the fifth main linkage unit along the longitudinal direction away from the opening and closing drive assembly 3. The first main linkage unit can be used to connect the opening and closing drive assembly 3.

[0030] Based on this, the number of secondary linkage units 222 can be determined according to the area of ​​each sub-sail assembly 2 when fully opened, with the standard that each sub-sail assembly 2 can be spliced ​​together to form a complete sail surface, and no specific limitation is required.

[0031] At this time, the multiple secondary link units 222 can be divided into two parts. The two parts of the secondary link units 222 can be symmetrically arranged on both sides of the longitudinal support 211. The multiple secondary link units 222 on either side are connected sequentially from the multiple main link units 221 and extend outward from the multiple main link units 221 to form a honeycomb mesh structure.

[0032] In one embodiment, please refer to Figure 4-5To connect the main connecting rod unit 221 to the longitudinal support 211, the slide rail on the longitudinal support 211 can be configured as a T-shaped structure. Correspondingly, the two connecting rods of any main connecting rod unit 221 can be hinged through a T-shaped bearing 5. The lower side of the T-shaped bearing 5 can be embedded in the slide rail of the longitudinal support 211, and a sliding fit can be formed between the bearing ball 51 at its bottom and the slide rail of the longitudinal support 211. In this way, it is ensured that each main connecting rod unit 221 can move longitudinally along the slide rail on the longitudinal support 211.

[0033] In one embodiment, the first main connecting rod unit described above can be connected to the transverse support 212 described above. Specifically, the slide rail on the transverse support 212 can be configured as a sliding groove passing through the transverse support 212, and the ends of the two connecting rods of the first main connecting rod unit near the transverse support 212 can be vertically fixed to the sliding rods, which can pass through the sliding grooves on the transverse support 212 to achieve a sliding connection between the two connecting rods of the first main connecting rod unit and the transverse support 212.

[0034] It is understandable that since the sub-sail assembly 2 is composed of multiple connecting rod units 22 with an X-shaped structure and forms a honeycomb mesh structure, the sequentially connected connecting rod units 22 can be moved by moving the ends of the two connecting rods on the first main connecting rod unit that are connected to the transverse support 212, thereby changing the distribution of each connecting rod unit 22 on the bearing support 21, so as to realize the opening or closing of the sub-sail assembly 2.

[0035] Please see Figure 6 In this embodiment, the sail device also includes a connecting component 4, which is set in a group between any two adjacent sub-sail components 2 in the circumferential direction. When each sub-sail component 2 is opened at the same time, each sub-sail component 2 can be connected through the connecting component 4, so that each sub-sail component 2 can be stably spliced.

[0036] Taking one of the connecting components 4 as an example, the connecting component 4 includes a first connector 41 and a second connector 42. The first connector 41 and the second connector 42 can be respectively set on the two corresponding sub-sail components 2, and the first connector 41 can be detachably connected to the second connector 42.

[0037] In one embodiment, please refer to Figure 7 The first connector 41 can be disposed on the connecting rod near the edge of the corresponding subsail assembly 2. The first connector 41 can be hinged to the end of the corresponding connecting rod near the adjacent subsail assembly 2, and has a mating groove 411 thereon. Correspondingly, the second connector 42 can be hinged to the adjacent subsail assembly 2 in the same manner, and has a mating protrusion 421 thereon.

[0038] In the above manner, when the two sub-sail components 2 are opened at the same time, the mating protrusion 421 on the second connector 42 can be embedded into the mating groove 411 on the first connector 41, and the two are fitted together to achieve splicing of the two sub-sail components 2.

[0039] In other embodiments, to improve the stability of splicing the two sub-sail components 2, a magnetic body (not shown in the figure) can be provided at the contact position of the above-mentioned mating groove 411 and / or mating protrusion 421. The magnetic body can be a permanent magnet, so that when the mating protrusion 421 is embedded in the corresponding mating groove 411, the first connector 41 and the second connector 42 can achieve magnetic adsorption through the magnetic body thereon.

[0040] In practical applications, to further ensure the stability of the splicing of each sub-sail component 2, each set of connecting components 4 may include multiple first connectors 41 and multiple second connectors 42. The multiple first connectors 41 may be respectively set at the ends of each connecting rod at the edge position of the corresponding sub-sail component 2, and the multiple second connectors 42 may be respectively set at the ends of each connecting rod at the edge position of adjacent sub-sail components 2. The first connectors 41 and the second connectors 42 are arranged in a one-to-one correspondence, so that multiple connection points formed by the first connectors 41 and the second connectors 42 can be formed between any two adjacent sub-sail components 2.

[0041] In this embodiment, each sub-sail assembly 2 is provided with a split sail surface 6. When each sub-sail assembly 2 is opened and spliced ​​together, the split sail surfaces 6 can be spliced ​​together to form a complete sail surface.

[0042] Please see Figure 8-9 Taking one of the split sails 6 as an example, the split sail 6 may include multiple flexible sail units 61, and the multiple flexible sail units 61 are detachably mounted on the corresponding sub-sail assembly 2.

[0043] Since the sub-sail assembly 2 is composed of the bearing support 21 and the aforementioned multiple connecting rod units 22, and the connecting rod unit 22 adopts an X-shaped structure formed by two connecting rods hinged together, the entire sub-sail assembly 2 can form a honeycomb mesh structure, and the shape of each honeycomb hole 23 can be a parallelogram (such as a rhombus).

[0044] At this time, the aforementioned multiple flexible sail units 61 can be detachably installed at the locations of the honeycomb holes 23 on the corresponding subsail assembly 2, and the honeycomb holes 23 at the corresponding locations can be sealed respectively.

[0045] In one embodiment, please refer to Figure 9Taking one of the flexible sail units 61 as an example, in order to assemble the flexible sail unit 61, the shape of the flexible sail unit 61 can be adapted to the shape of the honeycomb hole 23. For example, the shape of the flexible sail unit 61 can be set as a parallelogram (such as a rhombus), so that the four corners of the flexible sail unit 61 can respectively fit the corners of the corresponding honeycomb hole 23.

[0046] At this time, a bolt hole can be provided at each of the four corners of the flexible sail unit 61, and each bolt hole can be aligned with the corresponding hinge point of the connecting rod unit 22. Then, the flexible sail unit 61 can be detachably fixed at the corresponding honeycomb hole 23 using bolts.

[0047] Using the above method, when repairing the sail, first determine the subsail assembly 2 corresponding to the location to be repaired. Then, remove the connecting rod unit 22 corresponding to one or more flexible sail units 61, replace one or more flexible sail units 61 on the removed connecting rod unit 22, and finally reinstall it. The repair of any connecting rod unit 22 on any subsail assembly 2 can be carried out in a similar manner, which will not be elaborated here.

[0048] Please see Figure 2-3 The aforementioned opening and closing drive assembly 3 can be mounted on the fixed base 1 and located at the center of the circumference formed by the various sub-sail assemblies 2. The opening and closing drive assembly 3 can be connected to each sub-sail assembly 2 for transmission, so as to drive each sub-sail assembly 2 to open or close.

[0049] In one embodiment, the opening and closing drive assembly 3 may include a main shaft 31, a plurality of drive links 32, and a drive element.

[0050] The main shaft 31 can be vertically set at the center of the fixed base 1 and can be rotatably connected to the fixed base 1 through a bearing; the driving component can be a drive motor (obscured in the figure and not shown), the drive motor can be fixedly set on the fixed base 1 and can be connected to one end of the main shaft 31, so that the drive motor can drive the main shaft 31 to rotate on the fixed base 1.

[0051] To connect the main shaft 31 with each sub-sail assembly 2, multiple connecting posts 33 can be provided on the periphery of the main shaft 31. The multiple connecting posts 33 can be evenly distributed on the periphery of the main shaft 31. Taking any one of the connecting posts 33 as an example, the connecting post 33 can be arranged radially along the main shaft 31. One end of it can be fixedly connected to the side wall of the main shaft 31, while the end away from the main shaft 31 can be hinged to the adjacent end of the longitudinal support 211 on the corresponding sub-sail assembly 2.

[0052] Based on this, the aforementioned multiple drive linkages 32 can further connect the main shaft 31 to each sub-sail assembly 2 to realize the transmission between the main shaft 31 and each sub-sail assembly 2.

[0053] Specifically, each drive link 32 can be evenly distributed around the circumference of the main shaft 31. Taking any one of the drive links 32 as an example, one end of the drive link 32 can be hinged to the main shaft 31, and the other end can extend toward the corresponding sub-sail assembly 2 and connect to the adjacent link unit 22 on the sub-sail assembly 2. Taking the above five main link units 221 on the sub-sail assembly 2 as an example, the end of the drive link 32 away from the main shaft 31 can be hinged to the adjacent end of one of the links on the first main link unit.

[0054] In the above manner, when the drive motor drives the main shaft 31 to start rotating, the main shaft 31 can drive the end of the corresponding link on the first main link unit to slide along the transverse support 212 through the drive link 32, so that each main link unit 221 slides longitudinally on the longitudinal support 211, so that the distribution of each link unit 22 on the corresponding sub-sail assembly 2 changes synchronously, and finally realizes the opening or closing of the sub-sail assembly 2.

[0055] In one embodiment, please refer to Figure 2 For each subsail assembly 2, multiple limiting posts 7 can be vertically fixed on the side of the fixed base 1 near each subsail assembly 2, with each subsail assembly 2 corresponding to two of the limiting posts 7. Taking any one of the subsail assemblies 2 as an example, when the subsail assembly 2 is fully closed, the corresponding longitudinal support 211 can abut against one of the limiting posts 7, and when the subsail assembly 2 is fully open, the corresponding longitudinal support 211 can abut against the other limiting post 7.

[0056] Thus, each subsail assembly 2 can correspond to two limiting posts 7. These two limiting posts 7 can limit the extreme positions of the subsail assembly 2 when it is opened and closed, and prevent adjacent subsail assemblies 2 from being severely squeezed during the sail deployment and retraction process.

[0057] This invention also provides a vessel that may include the aforementioned sail assembly. A fixed base 1 is fixedly mounted on the vessel's mast, and a main shaft 31 is rotatably connected to the fixed base 1, allowing a drive motor to rotate the main shaft 31. The rotation of the main shaft 31 causes each sub-sail assembly 2 to open or close synchronously, thus achieving automatic sail deployment and retraction.

[0058] It should be noted that by applying the above-mentioned sail device to the vessel, the vessel can at least have all the beneficial effects of the above-mentioned sail device.

[0059] In practical applications, multiple sub-sail assemblies 2 and opening / closing drive assemblies 3 are respectively set on the fixed base 1. The multiple sub-sail assemblies 2 are circumferentially distributed on the periphery of the fixed base 1. The opening / closing drive assemblies 3 can drive each sub-sail assembly 2 to open or close, so as to realize the raising and lowering of the sail.

[0060] This not only helps to quickly raise and lower sails, saving time and effort and greatly improving the convenience of raising and lowering sails, but also reduces the risks caused by untimely raising and lowering of sails, thereby improving the safety of ship navigation.

[0061] Meanwhile, since each subsail assembly 2 is connected by a bearing support 21 and multiple connecting rod units 22, and each split sail surface 6 is spliced ​​together by multiple flexible sail surface units 61, when repairing the sail, the damaged parts can be repaired or replaced individually, which helps to shorten the repair time and reduce the repair cost.
