Description

Technical Field

[0001] This utility model belongs to the field of mooring device technology, specifically a suspended and liftable mooring structure. Background Technology

[0002] Suspended mooring structures are engineering systems that achieve stable positioning at sea by relying on buoyancy and dynamic constraint mechanisms. Through modular assembly and flexible design, they adapt to complex marine environments and maintain structural balance without relying on traditional rigid supports. The core of this technology lies in utilizing buoyancy to distribute loads. Its applications cover deep-sea energy development (such as floating wind power platforms and oil and gas production, storage, and offloading facilities), marine resource utilization (large aquaculture vessels and offshore photovoltaic power stations), transportation infrastructure (floating wharves and emergency refuge platforms), and marine aquaculture (aquaculture cages and platforms). It is particularly suitable for sea areas with depths exceeding 50 meters or complex geological conditions, providing a key technological solution for the expansion of marine engineering into the deep sea. Existing suspended mooring structures cannot adjust the height of marine aquaculture cages according to needs, making it difficult to adjust the immersion depth of the cages according to aquaculture requirements. If the cages are too high, they are prone to excessive algae attachment and biofouling, while if they are too low, they are prone to insufficient sunlight, which is not conducive to the growth of seafood and increases the risk of aquaculture. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a suspended liftable mooring structure, which effectively solves the problem that the existing suspended mooring structure cannot adjust the lifting and lowering of marine aquaculture cages according to needs, making it difficult to adjust the immersion depth of the cages according to aquaculture needs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suspended liftable mooring structure, comprising a device body, with first floating cylinders fixedly installed on both sides of the bottom of the device body, two second floating cylinders fixedly installed at both ends of the lower part of the device body, a support beam fixedly installed in the middle of the device body, a net fixedly installed at the bottom of the device body, a protective cover fixedly installed at the top of the support beam, and a servo motor fixedly installed inside the protective cover; The device has cables at the four lower corners of the main body, and mushroom-shaped anchors are fixedly installed at the bottom of each cable. The output end of the servo motor is equipped with a transmission component, which is connected to the four cables. When the servo motor is running, it drives the four cables to wind up through the transmission component.

[0005] Preferably, the transmission assembly includes a rotating shaft fixedly installed at the output end of the servo motor, the lower end of the rotating shaft extending into the interior of the support beam and fixedly installed with a driving bevel gear, and a driven bevel gear meshing with one side of the surface of the driving bevel gear.

[0006] Preferably, a first sealed bearing is rotatably mounted on the surface of the rotating shaft, and the surface of the first sealed bearing is rotatably connected to the support beam.

[0007] Preferably, a shaft is fixedly installed in the middle of the driven bevel gear, and the surface of the shaft is rotatably connected to the inner bottom of the support beam through two bearing seats. Worms are fixedly installed at both ends of the shaft, and the ends of the two worms that are far apart from each other are rotatably connected to the inner walls of both sides of the main body of the device.

[0008] Preferably, the lower part of the worm gear surface is meshed with a worm wheel, the middle of the two worm wheels is fixedly installed with a rotating rod, the surface of the two rotating rods is rotatably installed with two second sealed bearings, the surface of the two second sealed bearings is fixedly connected to the interior of the device body through a first baffle, the two ends of the two rotating rods are fixedly installed with a winding wheel, one side of the four winding wheels is rotatably connected to the inner wall of the device body, and the surface of the four winding wheels is fixedly connected to the upper end of the four cables. The four winding wheels and the four rotating rods are all made of metal material resistant to seawater corrosion.

[0009] Preferably, a second baffle is fixedly installed at both ends of the two sides inside the main body of the device, and the four second baffles can prevent seawater from entering.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator anchors four mushroom-shaped anchors into the seabed, and tightens the main body of the device by the mushroom-shaped anchors and four cables, thereby achieving mooring of the main body of the device. At the same time, the main body of the device floats on the sea surface by the first and second floating tubes. When it is necessary to adjust the immersion depth, the operator starts the servo motor to drive the active bevel gear to rotate. When the active bevel gear rotates, it drives the shaft to rotate through the driven bevel gear. When the shaft rotates, it drives two worm gears to rotate through two worm wheels. When the two worm wheels rotate, they drive two rotating rods to rotate. When the two rotating rods rotate, they drive four reels to rotate. As the four reels rotate, they wind up the four cables. Because the four mushroom-shaped anchors are firmly anchored to the seabed, the shortening of the four cables pulls the main body of the device and the net downwards, thereby increasing the immersion depth by pulling the main body of the device downwards. This allows the suspended mooring structure to adjust the raising and lowering of the aquaculture cages, thereby adjusting the immersion depth of the aquaculture cages, which is beneficial to the growth of seafood and reduces aquaculture risks.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Depend on Figures 1 to 4 The present invention includes a device body 1. First floating tubes 2 are fixedly installed on both sides of the bottom of the device body 1. Two second floating tubes 6 are fixedly installed at both ends of the lower part of the device body 1. The second floating tubes 6 and the first floating tubes 2 can make the device body 1 float on the sea surface. A support beam 3 is fixedly installed in the middle of the device body 1. The support beam 3 can improve the stability of the device body 1 and also serve to install transmission components. A net bag 4 is fixedly installed at the bottom of the device body 1. The net bag 4 is used to enclose seafood. A protective cover 5 is fixedly installed at the top of the support beam 3. A servo motor 9 is fixedly installed inside the protective cover 5. The protective cover 5 can protect the servo motor 9 from being corroded by the marine environment. The lower four corners of the main body 1 of the device are equipped with cables 8, and the bottom of each of the four cables 8 is fixedly installed with a fungus-shaped anchor 7. The four fungus-shaped anchors 7 are anchored to the seabed and the main body 1 of the device is moored by the four cables 8. The output end of the servo motor 9 is equipped with a transmission component, which is connected to the four cables 8. When the servo motor 9 is running, it drives the four cables 8 to wind up through the transmission component. The two ends of both sides inside the main body 1 are fixedly installed with second baffles 22. The four second baffles 22 can prevent seawater from entering and protect the transmission components.

[0015] In use, the operator anchors four mushroom-shaped anchors 7 into the seabed and tightens the main body 1 of the device through the mushroom-shaped anchors 7 and four cables 8, thereby mooring the main body 1 of the device. At the same time, the main body 1 of the device floats on the sea surface through the first floating tube 2 and the second floating tube 6. When it is necessary to adjust the immersion depth, the operator starts the servo motor 9 to drive the transmission component to rotate. When the transmission component rotates, it drives the four reels 20 to rotate. When the four reels 20 rotate, they wind up the four cables 8. Since the four mushroom-shaped anchors 7 are firmly anchored to the seabed, when the four cables 8 are wound down, they will pull the main body 1 and the net 4 downward, thereby increasing the immersion height by pulling the main body 1 downward. This allows the floating mooring structure to adjust the raising and lowering of the marine aquaculture cages, thereby adjusting the immersion depth of the aquaculture cages, which is beneficial to the growth of seafood and reduces aquaculture risks.

[0016] The transmission assembly includes a rotating shaft 10 fixedly mounted at the output end of the servo motor 9. The lower end of the rotating shaft 10 extends into the interior of the support beam 3 and is fixedly mounted with a driving bevel gear 11. A driven bevel gear 12 is meshed with one side of the surface of the driving bevel gear 11. The engagement of the driven bevel gear 12 and the driving bevel gear 11 can change the direction of rotational transmission. A first sealed bearing 13 is rotatably mounted on the surface of the rotating shaft 10, and the surface of the first sealed bearing 13 is rotatably connected to the support beam 3, so that the rotating shaft 10 can rotate within the first sealed bearing 13 and ensures the sealing between the rotating shaft 10 and the support beam 3. A shaft 14 is coaxially fixedly mounted in the middle of the driven bevel gear 12. The surface of the shaft 14 is rotatably connected to the inner bottom of the support beam 3 through two bearing seats 15, so that the shaft 14 can rotate within the two bearing seats 15 to ensure the stability of its rotational transmission. Worms 16 are fixedly mounted at both ends of the shaft 14. The ends of the two worms 16 that are far apart from each other are rotatably connected to the inner walls of both sides of the main body 1 of the device, thereby ensuring the stability of the rotational transmission of the two worms 16.

[0017] When the immersion depth needs to be adjusted, the operator starts the servo motor 9 to drive the active bevel gear 11 to rotate. When the active bevel gear 11 rotates, it drives the shaft 14 to rotate through the driven bevel gear 12. When the shaft 14 rotates, it drives the two worm gears 16 to rotate.

[0018] The lower part of the worm gear 16 is meshed with a worm wheel 17. The middle of each of the two worm wheels 17 is coaxially fixedly mounted with a rotating rod 19. The surface of each of the two rotating rods 19 is rotatably mounted with two second sealing bearings 18. The surface of each of the two second sealing bearings 18 is fixedly connected to the inside of the device body 1 through a first baffle 21. The first baffle 21 can prevent seawater from entering the support beam 3. The four second sealing bearings 18 can improve the sealing effect between the rotating rods 19 and the first baffle 21 while ensuring the rotational stability of the four rotating rods 19. Both ends of each of the two rotating rods 19 are fixedly mounted with a winding wheel 20. One side of each of the four winding wheels 20 is rotatably connected to the inner wall of the device body 1 to ensure the rotational stability of the four winding wheels 20. The surface of each of the four winding wheels 20 is fixedly connected to the upper end of each of the four cables 8, so that the four winding wheels 20 can wind and unwind the cables 8. The four winding wheels 20 and the four rotating rods 19 are all made of seawater-resistant metal materials to improve their service life.

[0019] When the two worm gears 16 rotate, they drive the two worm wheels 17 to rotate. When the two worm wheels 17 rotate, they drive the two rotating rods 19 to rotate. When the two rotating rods 19 rotate, they drive the four winding wheels 20 to rotate. When the four winding wheels 20 rotate, they wind up the four cables 8.
