Technical Field
[0001] This invention relates to the field of aquatic plant cultivation equipment technology, specifically to a rotating and opening seaweed transplanting and cultivation device and its control method. Background Technology
[0002] This invention relates to seagrass planting equipment technology. Current seagrass planting operations face multiple bottlenecks: at the tool level, existing equipment has fragmented functions, and its separate design leads to poor process integration. Furthermore, its mechanical structure is poorly adaptable to complex seabeds, easily damaging seedlings and reducing survival rates. At the operational process level, seedling cultivation, transportation, and planting are independent of each other, relying on manual transfer and secondary operations. This fragmented process makes coordination difficult and prevents large-scale continuous operations. At the system level, existing equipment relies on manual searching, digging, and planting of seagrass, making it difficult to adjust according to seabed soil conditions and seagrass distribution, thus hindering the guarantee of seagrass coverage.
[0003] The aforementioned problems result in low efficiency in seagrass cultivation, making it difficult to meet the demands for efficient and precise large-scale cultivation. Therefore, there is an urgent need for a seagrass transplantation and cultivation device and its control method based on a rotating, opening and closing mechanism. Summary of the Invention
[0004] To address the shortcomings of the existing technology, the present invention aims to provide a seagrass transplantation and cultivation device and control method based on a rotating and opening mechanism. Seagrass seedlings are transported to a dual-transfer assembly via a lifting and storing component. After sorting and positioning, they are transferred through a sliding hatch to a storage and rotating assembly in the underwater component. Under the transfer of the mechanical claw in the grasping component, they are placed in a telescopic chamber within the rotating planting assembly to await planting. Based on water and soil quality information fed back by an environmental sensing module, a soil loosening component and a sand flushing component loosen the soil. The rotating planting assembly completes the implantation and soil covering of the seagrass seedlings, integrating excavation and planting, achieving continuous operation of seedling cultivation, transportation, and planting, reducing redundancy in processes. The detection by the environmental sensing module further reduces root damage to the seedlings and improves positioning accuracy.

[0014] On the other hand, the present invention provides a control method for a rotating and opening seagrass transplantation and cultivation device, the specific steps of which include: S1, after the above-water and underwater components perform self-check and initialization operations, the propeller adjusts the spatial position of the above-water component according to the preset operating coordinates, so that the whole component moves to the upper part of the target sea area; the drive component of the underwater component cooperates with the shaftless propeller to adjust the depth and horizontal position of the underwater component, so that it moves precisely to the target planting point and completes docking with the docking joint of the above-water component through the docking interface; S2. The dual transfer assembly and the lifting storage assembly work together. The telescopic mechanical claw in the dual transfer assembly accurately grabs seedlings from the seedling tray and completes sorting and positioning under the combination of ball screw and synchronous belt. At the same time, the telescopic mechanical claw transports the seedlings through the sliding hatch to the cultivation chamber of the underwater component's storage rotating assembly. S3. The storage rotating component transports the cultivation chamber containing seedlings to the picking station of the mechanical claw in the gripping component via chain drive. The seedlings are then sent into the telescopic chamber of the rotary planting component through the linear guide rail combination, gear combination and multi-stage telescopic arm in the gripping component. S4. Start the drill bit of the loosening component to loosen the seabed sediment, and at the same time start the sand flushing component to remove surface gravel and attached materials. S5. Based on step S4, the lower shovel of the rotary planting component cuts into the seabed sediment, and the digging claw precisely plants the seedlings into the loosened soil. The hydraulic push rod provides a stable gripping force to ensure that the seedling planting depth and posture meet the requirements. Then, the soil loosening component reverses the drill bit to achieve natural soil covering of the planting point, completing the planting operation of a single seedling. Repeat the above steps to complete the planting operation of all seedlings.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The above-water component of this invention uses a propeller to power the seagrass seedlings, which are then transported to the dual-transfer component via a lifting and storage assembly. After sorting and positioning, the seedlings are transferred to the storage and rotation assembly of the underwater component via a sliding hatch. The underwater component, based on water and soil quality information from an environmental sensing module, loosens the soil, and then precisely plants the seagrass seedlings using a rotating planting assembly. This invention achieves functional integration through a docking mechanism between the above-water and underwater components, combining the underwater component's functions of water and soil quality detection, soil loosening, and seedling planting. This replaces traditional single-tool systems and eliminates the defects of existing technologies such as "separation of excavation and planting, and redundant procedures." Simultaneously, by utilizing the underwater component's drive assembly and shaftless propeller, it adapts to complex seabed environments such as reefs and silt, reducing the risk of seedling root damage and solving the problems of "inaccurate positioning and low survival rate."
[0016] 2. After the seedling pretreatment is completed by the lifting and storage component of the above-water component of the present invention, the seedlings are accurately transferred to the storage and rotation component of the underwater component by the dual transfer component, realizing continuous operation of seedling cultivation, transportation and planting, and alleviating the shortcomings of "manual transfer and process fragmentation" in the prior art; and the underwater component can move and dock autonomously and automatically replenish seedlings, without the need for manual intervention in the whole process, reducing coordination costs and supporting large-scale planting.
[0017] 3. The environmental sensing module of the underwater component of the present invention can complete the water quality and soil quality assessment before planting, and start the operation only when the environment is qualified, avoiding the waste of resources from blind operation; at the same time, the rotating planting component, the soil loosening component and the sand flushing component combine with the environmental data collected by the environmental sensing module to achieve precise positioning. The rotating planting component completes the seedling implantation and soil covering by the grabbing component, replacing the traditional extensive operation and significantly improving the planting accuracy.
[0018] 4. The above-water component of this invention adopts a biomimetic streamlined shell to reduce water flow resistance, ensure the device can stay safely in the water for a long time, and improve operational stability; the rotating planting component of the underwater component uses a biomimetic crab claw to terminate and dig up the whole plant on the seabed, which greatly protects the integrity of the plant and helps to improve the survival rate; the rotating storage component enables independent storage of seedlings, avoids cross-contamination, and each functional module can be maintained independently, effectively reducing equipment failure rate and maintenance costs.

The sea valve 1103 and the gas valve 1104 are located at the first and second mounting ends on the side of the ballast tank 1105, respectively. When the electric ballast tank assembly 10 submerges, the sea valve 1103 and the air valve 1104 open, and seawater automatically flows into the ballast tank 1105, realizing the submersion of the device; when the electric ballast tank assembly 10 ascends, the air valve 1104 closes, and the air compressor 1102 releases air under the drive of the submersible motor 1101, and the seawater is discharged from the cavity through the sea valve 1103, realizing the ascent of the device. The electric ballast tank assembly 10 controls the large-scale ascent and descent of the underwater components, and the shaftless thruster 15 makes small-scale fine adjustments.
[0033] The rotating planting component 16 is installed in the middle and front part of the underwater component, such as... Figure 11 and Figure 12As shown, the device includes a rotating wheel 1601, a guard plate 1602, a lower shovel 1603, a digging claw 1604, a telescopic cabin 1605, a telescopic cabin door 1606, a hydraulic push rod 1607, a servo motor 1608, a lead screw and slide rail 1609, and a second stepper motor 1610. The input end of the rotating wheel 1601 is connected to the output end of the second stepper motor 1610. The fixed end of the rotating wheel 1601 is connected to the first mounting end of the guard plate 1602. The lower shovel 1603 and the digging claw 1604 are connected to the second and third mounting ends of the guard plate 1602, respectively. The control end of the digging claw 1604 is connected to the servo motor 1608. The fourth mounting end of the guard plate 1602 is connected to the first mounting end of the telescopic cabin 1605 via the lead screw and slide rail 1609. The second mounting end of the telescopic cabin 1605 is connected to the telescopic cabin door 1606 via the hydraulic push rod 1607.
[0034] Furthermore, the telescopic hatch 1606 is opened and closed by a hydraulic push rod 1607. The lower shovel 1603, serving as the base and front-end actuator of the rotary planting assembly 16, has a shovel-shaped structure and is used to cut into the soft seabed, providing support for subsequent digging operations. It also receives seaweed seedlings or planting substrate grabbed by the digging claw 1604. The digging claw 1604 and the lower shovel 1603 work together to form an openable claw-like structure, which is opened and closed by a servo motor, achieving soil cutting and grabbing the target material from the seabed to prevent it from scattering. The servo motors 1608 and rubber pad structures on both sides of the rotary planting assembly 16 are used to assist in adjusting the cutting angle and attitude of the lower shovel 1603, ensuring stability during the digging process. The rubber pads also cushion the impact of the device contacting the seabed, preventing excessive disturbance to the seabed.
[0035] The soil loosening component 18 consists of two sets, symmetrically distributed on both sides of the front end of the underwater component. These are used for initial adjustment of the device's attitude, driving the drill bit 1814 to make fine-tuning adjustments to its angle, thereby achieving multi-degree-of-freedom soil loosening operations, such as... Figure 14 and Figure 15As shown, it includes a fourth motor 1801, a motor mounting plate 1802, a thin-walled bearing 1803, a bearing pressure plate 1804, a first-stage telescopic arm inner plate 1805, a first-stage telescopic arm middle plate 1806, a first-stage telescopic arm outer plate 1807, an electric actuator 1808, a second-stage telescopic arm 1809, a slider 1810, a slide rail 1811, a fifth motor 1812, a bearing 1813, and a drill bit 1814. The motor mounting plate 1802 is fixed to the inner wall of the underwater component by bolts. The fixed end of the fourth motor 1801 is connected to the motor mounting plate 1802. The drive end of the fourth motor 1801 is connected to the drive end of the first-stage telescopic arm inner plate 1805 through the inner hole of the thin-walled bearing 1803. The mounting end of the first-stage telescopic arm inner plate 1805 is connected to the bearing pressure plate 1804. The first-stage telescopic arm inner plate 1805 and the first-stage telescopic arm middle plate 1804 are connected to each other. 806 and the outer plate 1807 of the first-stage telescopic arm are connected in sequence to form the first-stage telescopic arm. The first-stage telescopic arm can rotate to achieve the initial adjustment of the device's posture, driving the drill bit 1804 to adjust its angle, thereby achieving multi-angle soil loosening operations and improving the flexibility and accuracy of excavation or sampling. The fixed end of the electric actuator 1808 is connected to the mounting end of the outer plate 1807 of the first-stage telescopic arm, and the extended end of the electric actuator 1808 is connected to the first mounting end of the second-stage telescopic arm 1809.

[0036] like Figure 13 As shown, the sand flushing component 19 is used to quickly clean the silt, loose sand, and attached materials on the surface of the planting point. It forms a main impact jet and a supplementary jet through a rotating high-pressure sand flushing pipe to disperse the surface sediment, washing away loose surface deposits, reducing soil density, and ensuring a clean and flat substrate, creating favorable conditions for precise seedling planting. This improves the efficiency and stability of soil loosening and seaweed transplanting operations. The component includes a nozzle 1901, a water collector 1902, a rotating platform 1903, and a spherical camera 1904. The water collector 1902 is located on top of the rotating platform 1903, and its output end is connected to the nozzle 1901. The spherical camera 1904 is connected to the mounting end of the rotating platform 1903. The spherical camera 1904 transmits images to the control terminal in real time, allowing for dynamic adjustment of the rotation angle, pressure, and primary and secondary flow ratios to optimize flushing efficiency and thoroughness.
[0037] In the control method of the rotating and opening seagrass transplanting and cultivation device, when the lifting and storage component 8 of the above-water component is activated, the seedlings are transported to the working area of the double transfer component 3 by the electric push rod 806 that installs the seedling tray 805; after the double transfer component 3 completes the positioning and gripping by the telescopic mechanical claw 308, the sliding door 14 opens, and the seedlings are transferred to the storage and rotating component 12 of the underwater component; when the chain 1208 of the storage and rotating component 12 rotates under the drive of the DC motor, the cultivation chamber 1205 carrying the seedlings rotates to the discharge port, and the multi-stage telescopic arm 1014 of the gripping component 10 grips the seedlings; when After the underwater component's environmental sensing module 17 completes water and soil quality detection, the soil loosening component 18, via the primary and secondary telescopic arms 1809, adjusts the soil penetration depth of the drill bit 1814. The drill bit 1814 rotates synchronously with the driving component 9 to complete soil loosening. The sand flushing component 19 then performs secondary cleaning to remove gravel. At this time, the rotary planting component 16 plants the seedlings located in the telescopic pod 1605 into the loosened seabed area. When it is necessary to adjust the device's operating position, the underwater component's driving component 9 moves the device, and the underwater component maintains its underwater operating posture through the electric ballast tank component 11 and the shaftless thruster 15. The specific implementation process is as follows: S1. After the surface and underwater components perform self-checks and initialization, the thruster 1 adjusts the spatial position of the surface component according to the preset operating coordinates, moving it as a whole above the target sea area. At this time, the seaweed seedlings in the seedling tray 805 in the lifting and storage assembly 8 maintain their activity under the care of the light and irrigation pretreatment system. The drive assembly 9 of the underwater component cooperates with the shaftless thruster 15 to adjust the depth and horizontal position of the underwater component, so that it moves precisely to the target planting point and completes docking with the docking connector 7 of the surface component through the docking interface 13.
[0038] S2. The dual transfer assembly 3 and the lifting and storage assembly 8 work together. The telescopic mechanical claw 308 in the dual transfer assembly 3 accurately grabs the seedlings from the seedling tray 805 and completes sorting and positioning under the combination of ball screw and synchronous belt. At the same time, the telescopic mechanical claw 308 transports the seedlings through the sliding hatch 14 to the cultivation chamber 1205 of the underwater component's storage and rotation assembly 12.
[0039] S3. The environmental sensing module 17 is activated to detect the water quality and soil parameters of the target area. If the detection results meet the preset planting standards, the storage rotating component 12 will transport the cultivation chamber 1205 containing the seedlings to the picking station of the mechanical claw 1011 in the gripping component 10 via the chain 1208. The seedlings will be sent into the telescopic chamber 1605 of the rotary planting component 16 through the linear guide rail combination, gear combination and multi-stage telescopic arm 1014 in the gripping component 10. If the detection results do not meet the preset planting standards, the planting points will be replanned.
[0040] S4. Start the loosening component 18. Through the coordinated adjustment of the angle of the first-stage telescopic arm and the second-stage telescopic arm 1809, drive the drill bit 1814 to loosen the seabed sediment, creating a suitable soil environment for seedling planting. At the same time, start the sand flushing component 19 to remove surface gravel and attached materials.
[0041] S5. Based on step S4, the lower shovel 1603 of the rotary planting component 16 cuts into the seabed sediment, the digging claw 1604 accurately plants the seedling into the loosened soil, and the hydraulic push rod 1607 provides a stable gripping force to ensure that the seedling planting depth and posture meet the requirements. Then, the soil loosening component 18 reverses the drill bit 1814 to achieve natural soil covering of the planting point, completing the planting operation of a single seedling.
[0042] Once a single seedling has been planted, it sends a signal to the central control system indicating that the seedling retrieval is complete. The central control system then decides, based on the preset total task volume, to start the planting cycle for the next seedling, or to trigger an end / reset command to return to the initial state and wait for the next task.
[0043] This invention enhances the overall operational integration through the coordinated operation of surface and underwater components, enabling integrated transportation, planting, and transplantation of seagrass plants. The soil-loosening component, working in conjunction with the rotating planting component, smoothly performs soil digging, plant placement, and soil burying when rotating forward. When rotating backward, the soil-loosening component removes the entire plant along with the soil, reducing damage to the plants and soil during operation. The environmental sensing module detects and identifies the distribution of seabed plants and soil conditions, ensuring dense planting and improving plant survival rates. The biomimetic streamlined shell and modular design reduce resistance during underwater operations, increasing operational flexibility. This device is widely used in marine restoration, seagrass cultivation, and marine surveillance, among other fields.
