Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine cultivation, in particular to a seaweed cultivation device for marine ecological restoration. BACKGROUND

[0002] With the intensification of human activities on global marine ecosystems, natural seaweed habitats continue to degrade, leading to weakened ecological functions such as water purification, carbon sequestration and storage, and biodiversity maintenance. Since seaweed relies on specific substrates for attachment and growth in nature, and degraded marine areas often lack suitable growth environments, the natural recovery rate is much lower than the ecological degradation rate. Meanwhile, advances in material science and marine engineering technology have provided technical support for the construction of artificial cultivation carriers that can adapt to complex environments such as ocean waves, tides, and biological fouling. In this context, seaweed cultivation devices for marine ecological restoration have emerged, aiming to provide suitable attachment and growth conditions for seaweed by artificially constructing stable growth substrates and optimizing environmental adaptability, thereby assisting in the functional recovery of damaged marine ecosystems.

[0003] Existing seaweed cultivation devices artificially construct reef-like substrates to simulate natural seaweed attachment, providing settlement sites for seaweed spores. The top of the reef is suspended in the ocean by airbags, and the bottom is fixed to the seabed by counterweights to resist water flow and wave disturbances and maintain structural stability. With the help of naturally circulating nutrients and light conditions transported by the ocean, the device enables the gradual restoration of marine ecological functions through natural seaweed propagation. However, the existing seaweed cultivation device has fixed attachment substrates that cannot dynamically adjust spatial positions according to light conditions, resulting in insufficient light for algae below the substrate, limited photosynthesis, and poor wave and tide impact resistance of the attachment plate, making it difficult to withstand ocean waves and strong water flow, which hinders the stable attachment of seaweed seedlings. Therefore, the present application proposes a seaweed cultivation device for marine ecological restoration to address the shortcomings of existing technology. SUMMARY

[0004] To address the shortcomings of existing technology, the present application provides a seaweed cultivation device for marine ecological restoration, which solves the problem of insufficient light for algae below the substrate, limited photosynthesis, and poor wave and tide impact resistance of the attachment plate, making it difficult to withstand ocean waves and strong water flow, which hinders the stable attachment of seaweed seedlings.

[0021] Preferably, the anchoring device can be one or more of gravity anchors and bottom-gripping anchors.

[0022] This invention provides a seaweed cultivation device for marine ecological restoration. It has the following beneficial effects:

[0023] 1. By adjusting the structure of the mechanism, the magnetic block's attraction to the toothed disc ensures the stability of the meshing between the toothed disc and the toothed plate, locking the angle of the attachment plate and making the seaweed receive light more evenly. Through the cooperation of the torsion spring and the bearing, a buffer space is provided for the attachment plate under the impact of sea waves, avoiding the rigid impact of seawater on the seaweed on the surface of the attachment plate. At the same time, after the impact of seawater, the torsion spring can be used to reset the attachment plate to the preset angle. This solves the problem that the space position cannot be dynamically adjusted according to the light conditions, resulting in insufficient light for the algae under the substrate, which affects the growth of the seaweed. In addition, the attachment plate has poor wave impact resistance and is difficult to resist the disturbance of sea waves and strong water currents, making it difficult for algae seedlings to attach stably.

[0024] 2. Through the structural design of the connecting mechanism, the cylindrical spring uses its own elastic force to drive the first and second locking blocks to engage, ensuring the stability of the connection between the attachment plate and the rotating rod. At the same time, it allows the attachment plate to be quickly disassembled. The sealing assembly composed of the first sealing ring, the waterstop, and the second sealing ring prevents the intrusion of mud and sand from the ocean into the rotating rod, reducing the risk of internal structural jamming and improving the structural reliability and long-term stability of the device in the marine environment.

[0025] 3. The structural design of the distance measuring mechanism, along with the cooperation between the mounting base and the connecting groove, provides guidance for the assembly of the mounting block and attachment plate, improving the efficiency of component docking during the onshore planting stage. The hook and hemp rope can measure the horizontal and vertical spacing between plants. At the same time, the automatic winding of the hemp rope is achieved by driving the winding rod through the spring, which simplifies the operation process and avoids the situation where the intelligent distance measuring device used for measuring the distance between plants is prone to insufficient power or equipment damage and measurement difficulties outdoors by utilizing the elasticity of the spring.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-6This invention provides a seaweed cultivation device for marine ecological restoration, comprising a frame 1, which provides stable support for the entire seaweed cultivation device and bears the overall structure. A buoyancy device 2 is installed above the frame 1, allowing the seaweed cultivation device to suspend in the ocean using its own buoyancy characteristics. An attachment plate 3 is installed inside the frame 1 via an adjustment mechanism 5, providing a growth carrier for the seaweed and enabling stable growth in the ocean. The adjustment mechanism 5 is used to adjust the angle of the attachment plate 3, allowing for seasonal adjustment of the light angle. A distance measuring mechanism 7 is installed on the front side wall of the attachment plate 3, providing a spacing reference when the seaweed is planted on the surface of the attachment plate 3. An anchoring device 4 is installed at the bottom of the frame 1 for anchoring... Device 4 allows frame 1 to be stably placed in the ocean. Adjustment mechanism 5 includes a first pull rod 8 slidably connected inside frame 1. Frame 1 provides stable movement space and movement guidance for the first pull rod 8. Gear disc 9 is slidably connected inside frame 1. The end of the first pull rod 8 near attachment plate 3 is fixedly connected to gear disc 9. The first pull rod 8 can drive gear disc 9 to move synchronously inside frame 1. Slider 10 is fixedly connected to the surface of gear disc 9. When driving gear disc 9 to move, gear disc 9 can move synchronously with slider 10. At least one guide groove 11 is opened inside frame 1. Slider 10 is slidably connected inside guide groove 11. Guide groove 11 provides movement guidance for slider 10. At the same time, slider 10 can be limited inside guide groove 11. The guide groove 11 limits the slider 10, thereby limiting the angle of the gear disk 9. A toothed plate 12 is rotatably connected to the inner side of the frame 1. The gear disk 9 and the toothed plate 12 mesh with each other. The meshing of the gear disk 9 and the toothed plate 12 can fix the rotation of the toothed plate 12 inside the frame 1. The disengagement of the toothed plate 12 and the gear disk 9 allows the toothed plate 12 to rotate inside the frame 1. A magnetic block 13 is fixedly connected to the inner side of the toothed plate 12. The magnetic block 13 can rotate inside the frame 1 through the toothed plate 12. The magnetic block 13 is magnetically connected to the gear disk 9. The magnetic attraction between the magnetic block 13 and the gear disk 9 allows the gear disk 9 to automatically reset after movement. Two rotating cylinders 14 are arranged opposite each other inside the frame 1. The frame 1 is the rotating cylinder 14. Providing stable rotational support and rotational space, a rotating cylinder 14 is connected to the side of the magnetic block 13 away from the slider 10. One of the rotating cylinders 14 is fixedly connected to the magnetic block 13. Rotation of the rotating cylinder 14 can drive the magnetic block 13 and the toothed plate 12 to rotate synchronously. A buffer assembly is provided on the inner side of the rotating cylinder 14. The buffer assembly can provide buffering force when the attachment plate 3 is impacted by seawater, preventing the seaweed on the surface of the attachment plate 3 from being washed away. A connecting mechanism 6 is provided below the adjusting mechanism 5. The connecting mechanism 6 can realize the quick connection between the attachment plate 3 and the rotating rod 17. The connecting mechanism 6 includes a sealing assembly. The connecting mechanism 6 is used to connect the attachment plate 3 and the adjusting mechanism 5, enabling quick assembly and disassembly of the attachment plate 3 and the adjusting mechanism 5. The buffer assembly includes a bearing 15.Bearing 15 is located inside the rotating cylinder 14, providing a foundation for the smooth rotation of the rotating rod 17 inside the rotating cylinder 14. One end of a torsion spring 16 is fixedly connected to the inside of the rotating cylinder 14, and the other end of the torsion spring 16 is connected to the corresponding fixed shaft of the rotating rod 17. Through the connection between the torsion spring 16, the rotating cylinder 14, and the rotating rod 17, the attachment plate 3 is subjected to seawater erosion, causing the rotating rod 17 and the attachment plate 3 to rotate to a certain extent, providing a buffering effect for the attachment plate 3. The fixed shaft of the rotating rod 17 is rotatably connected inside the rotating cylinder 14, and the bearing 15 is fixedly connected to the fixed shaft of the rotating rod 17, so that when the seawater moves the attachment plate 3, the rotating rod 17 can rotate smoothly inside the rotating cylinder 14, providing buoyancy. Device 2 can be one or more of the following: closed-cell foam ball, hollow cavity ball, or composite buoyancy ball. Closed-cell foam balls have an internal closed-cell structure that seals independent air bubbles, making them non-absorbent, leak-proof, and providing high buoyancy per unit volume. Hollow cavity balls achieve buoyancy by storing air in sealed cavities; the cavity material itself is resistant to seawater corrosion. Composite buoyancy balls use lightweight foam as their core to provide basic buoyancy, while the outer layer resists wave impact and prevents foam breakage. Anchoring device 4 can be one or more of the following: gravity anchor or bottom-gripping anchor. Gravity anchors press down on the seabed by their own weight, utilizing the friction between the seabed and the bottom of the anchor to resist tensile forces. Bottom-gripping anchors rely on mechanical structures to firmly grip the seabed and are suitable for medium-deep seas or hard seabeds.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8The connecting mechanism 6 includes two second pull rods 18 slidably connected to the inner side of the rotating rod 17. The rotating rod 17 provides movement space and movement guidance for the second pull rods 18. A cylindrical spring 19 is sleeved on the surface of each second pull rod 18. One end of each cylindrical spring 19 is fixedly connected to the inner side of the rotating rod 17, providing a stable force point for the cylindrical spring 19. A first locking block 20 is fixedly connected to the other end of each cylindrical spring 19 on the attachment plate. The cylindrical spring 19 provides stable elastic support for the first locking block 20, enabling it to automatically reset after movement. Two mounting slots 21 are provided at the bottom of the rotating rod 17, providing stable installation guidance space for the second locking block 22. The surface of the first locking block 20... The first locking block 20 engages with the second locking block 22, which is secured by the first locking block 20. The second locking block 22 is slidably connected inside the mounting groove 21. When the attachment plate 3 is connected to the rotating rod 17, the second locking block 22 follows the attachment plate 3 into the mounting groove 21. A slot 23 is provided on the side of the second locking block 22 near the first locking block 20, and the second locking block 22 engages inside the slot 23. The slot 23 provides space for the engagement between the first locking block 20 and the second locking block 22, and also provides an accurate positioning point for the second locking block 22. A sealing component is provided between the attachment plate 3 and the rotating rod 17 to seal the connection between the attachment plate 3 and the rotating rod 17. To prevent marine sediment from entering and damaging the internal structure, the sealing assembly includes a base plate 24 fixedly connected to the top of the attachment plate 3. A first sealing ring 25 is fixedly connected to the top of the base plate 24. The attachment plate 3 can drive the base plate 24 and the first sealing ring 25 to be installed synchronously. The top of the first sealing ring 25 has a groove 26, which provides a connection space for a second sealing ring 28 to the first sealing ring 25. A waterstop 27 is fixedly connected to the inner side of the first sealing ring 25, and the top of the waterstop 27 abuts against the second sealing ring 28. The waterstop 27 can expand when exposed to water to seal the gap at the connection between the first sealing ring 25 and the second sealing ring 28, enhancing the sealing effect. The second sealing ring 28 is fixedly connected to the rotating... Inside the rod 17, the rotating rod 17 provides a stable installation space and mounting carrier for the second sealing ring 28. The base plate 24 abuts against the bottom of the rotating rod 17. Through the abutment between the rotating rod 17 and the base plate 24, the rotating rod 17 can form a sealed cavity. The waterstop 27 is a rubber waterstop. The rubber waterstop has the ability to resist seawater corrosion and weather resistance. The contact sidewalls of the first locking block 20 and the second locking block 22 are both rounded corner structures. The rounded corner structure can reduce the locking resistance between the first locking block 20 and the second locking block 22. Through the setting of the rounded corner structure, the first locking block 20 can be moved during the process of pushing the second locking block 22 in, providing connection space for the second locking block 22, and enhancing the convenience of connecting the second locking block 22.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 9, Figure 10 The ranging mechanism 7 includes a mounting base 29 fixedly connected to the bottom of the front side wall of the attachment plate 3. The attachment plate 3 provides a stable mounting carrier for the mounting base 29. A connecting groove 30 is provided inside the mounting base 29, which provides a stable installation guide for the connecting block 32. A mounting block 31 is slidably connected to the surface of the mounting base 29. A connecting block 32 is fixedly connected to the side of the mounting block 31 near the mounting base 29. The mounting block 31 and the connecting block 32 can be installed into the mounting base 29 synchronously. Two telescopic rods 33 are rotatably connected inside the mounting block 31. The telescopic rods 33 can measure the plant spacing on the surface of the attachment plate 3 in both horizontal and vertical directions. An installation cavity 34 is fixedly connected to the end of the telescopic rod 33 away from the mounting block 31. As the telescopic rod 33 is stretched, it can drive the installation cavity 34 to move synchronously. A wire feeding assembly is provided inside the installation cavity 34. The wire feeding assembly can wind up the hemp rope 37. The wire feeding assembly includes one end of a spring 35 fixedly connected inside the installation cavity 34. The mounting cavity 34 provides stable support for the spring 35. A winding rod 36 is fixedly connected to the end of the spring 35 furthest from the mounting cavity 34. The spring 35 provides stable elastic support for the winding rod 36, allowing it to automatically reset after rotation. The winding rod 36 is rotatably connected inside the mounting cavity 34. One end of a hemp rope 37 is fixedly connected to the surface of the winding rod 36. Pulling the hemp rope 37 causes the winding rod 36 to rotate synchronously inside the mounting cavity 34. A hook 38 is fixedly connected to the end of the hemp rope 37 furthest from the winding rod 36, providing a base for fixing the hemp rope 37. The connecting block 32 and the connecting groove 30 have a T-shaped structure. The T-shaped structure of the connecting block 32 and the connecting groove 30 allows the connecting block 32 to stably engage inside the connecting groove 30, enhancing stability during measurement. The telescopic rod 33 has graduations on its surface, providing a reference for the distance between plants.

[0042] Working principle: During use, when planting seaweed on the shore, the installation block 31, guided by the connecting block 32 and the connecting groove 30, is installed into the mounting base 29. Then, one of the telescopic rods 33 is rotated, allowing it to measure the attachment plate 3 in both horizontal and vertical directions. While pulling the telescopic rod 33, the hook 38 is pulled, causing the rope 37 to be pulled out from the mounting cavity 34. As the rope 37 is pulled, it drives the winding rod 36 to rotate, causing the spring 35 to contract and store elasticity. The hook 38 is then hung on the other side of the attachment plate 3. The distance between the plants can then be measured through the surface of the telescopic rod 33. After measurement, the hook 38 is removed, and the spring... Under the action of the elastic force, the winding rod 36 rotates, winding the hemp rope 37 onto the surface of the winding rod 36. Then, the mounting block 31 can be removed. Subsequently, the attachment plate 3 drives the second locking block 22 to be installed into the rotating rod 17 along the guide of the mounting groove 21. During the installation process, the rounded corner of the second locking block 22 contacts the rounded corner of the first locking block 20. The second locking block 22 pushes the first locking block 20 and the second pull rod 18 to move. The first locking block 20 compresses the cylindrical spring 19, causing the cylindrical spring 19 to store elastic force. After the attachment plate 3 is installed in place, the cylindrical spring 19 drives the first locking block 20 and the second pull rod 18 to reset. The first locking block 20 enters the locking groove 23, limiting the second locking block 22 inside the mounting groove 21, thus fixing the attachment plate 3 inside the rotating rod 17. Simultaneously, the base plate 24, along with the attachment plate 3, moves the first sealing ring 25 into the rotating rod 17. The second sealing ring 28 then mechanically enters the groove 26, abutting against the waterstop 27 to seal the connection between the base plate 24, the attachment plate 3, and the rotating rod 17, preventing sediment from entering the rotating rod 17 and damaging its internal structure. When disassembling the attachment plate 3, the second pull rod 18 is pulled, causing the first locking block 20 to move synchronously and disengage from the slot 23, releasing the restriction on the second locking block 22. The attachment plate 3 can then be removed from the rotating rod 17. The frame 1, along with the entire device, is then placed into the marine purification area. The anchoring device 4 sinks into the sea to position the frame 1, and the buoyancy device 2 suspends the frame 1 and the attachment plate 3 in the sea. In the water, the angle of the attachment plate 3 can be adjusted according to the light. During the adjustment process, pulling the first lever 8 overcomes the magnetic attraction between the magnet 13 and the toothed disc 9, causing the first lever 8 to drive the slider 10 to slide along the guide groove 11. At this time, the toothed disc 9 and the toothed plate 12 are disengaged, and the toothed disc 9 releases its restriction on the toothed plate 12. Then, the attachment plate 3 can be rotated to drive the rotating rod 17 and the rotating cylinder 14 to rotate, adjusting the angle of the attachment plate 3. After the adjustment is completed, releasing the second lever 18 allows the magnetic attraction of the magnet 13 on the toothed disc 9 to reset the toothed disc 9 and re-engage with the toothed plate 12, thereby fixing the angle of the attachment plate 3. When the attachment plate 3 encounters seawater impact, the attachment plate 3 drives the rotating rod 17 to rotate inside the rotating cylinder 14 through the bearing 15.Simultaneously, the torsion spring 16 deforms, providing cushioning for the attachment plate 3 when impacted by seawater, allowing the attachment plate 3 to rotate within a certain angle range. After the seawater impact subsides, the torsion spring 16 can drive the attachment plate 3 to reset, placing it at an adjusted angle so that the seaweed can receive sunlight evenly on its surface.
