It can be adjusted to meet different oyster survival environments.
[0025] 2. The oyster raft-type marine aquaculture device provided by this utility model uses a first inclined rod to push a slider to slide in a groove when the protective plate is impacted by external force. This, together with a damping spring and damper, provides a buffering effect. At the same time, the rotation of the second inclined rod further disperses the impact force, achieving effective protection for the floating plate and the entire aquaculture device. In the complex and changeable marine environment, unexpected situations such as ship collisions and floating object impacts may occur. This protective device can reduce the risk of damage to the aquaculture device caused by these external forces, ensure the integrity and normal operation of the aquaculture device, and reduce oyster farming losses caused by device damage.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0034] Reference Figure 1 This utility model discloses an oyster marine raft aquaculture device, including a floating plate 1, which serves as the basic load-bearing component of the entire aquaculture device. Floating on the sea surface, it provides installation positions for other components. A connecting sleeve 2 is fixedly connected to the inner wall of the top of the floating plate 1. Connecting rods 5 are fixed at each of the four corners of the floating plate 1, and a floating ball 6 is fixedly connected to one end of each connecting rod 5. The floating balls 6 increase the buoyancy of the entire aquaculture device on the sea surface, ensuring that the floating plate 1 can float stably on the water. Even when subjected to certain wind and waves or bearing the weight of farmed oysters, it can maintain a good floating state and not sink. A second filter sleeve 11 is threadedly connected to the outer ring of the bottom of a sliding sleeve 25. A first filter sleeve 10 is provided on the inner wall of the second filter sleeve 11, and the first filter sleeve 10 is threadedly connected to the sliding sleeve 25. The second filter sleeve 11 and the first filter sleeve 10 can be relatively fixed or disassembled with the sliding sleeve 25 through threaded connection. This device provides functions such as seawater filtration and providing food for the oysters.
[0035] Reference Figure 2 , Figure 3 and Figure 5 A wind turbine 3 is fixedly connected to the top of the connecting sleeve 2. The wind turbine 3 will rotate under the action of the sea breeze, and generate electrical energy through this rotation to provide power for the operation of the subsequent device. A sliding sleeve 25 is slidably connected to the inner wall of the connecting sleeve 2, and the sliding sleeve 25 is slidably connected to the inner wall of the floating plate 1. A storage battery 7 is fixedly connected to the inner wall of the sliding sleeve 25, and the storage battery 7 is electrically connected to the wind turbine 3. There is an electrical connection between the storage battery 7 and the wind turbine 3. This allows the electrical energy generated by the wind turbine 3 to be effectively collected and stored in the battery 7, providing a stable power supply for other electrical devices when needed. A motor 8 is fixedly connected to the top of the connecting sleeve 2. As a power drive component, the motor 8, upon receiving power from the battery 7, drives the lead screw 21 to rotate. The output end of the motor 8 is fixedly connected to the lead screw 21, and the motor 8 drives the lead screw 21 to rotate. A nut pair 22 is threadedly connected to the outer ring of the bottom of the lead screw 21. A movable seat 23 is fixedly connected to the bottom of the nut pair 22. When the lead screw 21 rotates, based on the principle of the threaded connection, the nut pair 22 will move up and down accordingly. Since the movable seat 23 is fixedly connected to the bottom of the nut pair 22, the movement of the nut pair 22 will directly drive the movable seat 23 to move synchronously. Connecting posts 24 are fixedly connected to both the front and rear ends of the bottom of the movable seat 23, and the connecting posts 24 are fixedly connected to the inner wall of the sliding sleeve 25.
[0036] Reference Figure 4 The outer wall of the floating plate 1 is provided with a protective assembly, including a protective plate 4. The protective plate 4 is arranged on all four sides of the floating plate 1. One end of the protective plate 4 is fixedly connected to a uniformly distributed first connecting block 13. The outer wall of the first connecting block 13 is rotatably connected to a first inclined rod 12. When the protective plate 4 is impacted by an external force, the first inclined rod 12 will push the slider 17 to slide in the groove 15. At this time, the damping spring 16 and the damper 20 will play a buffering role, reducing the impact of the external force on the floating plate 1 and the entire aquaculture device. A fixed plate 14 is provided on the opposite side of the protective plate 4. The fixed plate 14 has a groove 15 inside, and the slider 17 is slidably connected inside the groove 15. The slider 17 rotates with the first inclined rod 12. The inner wall of the fixed plate 14 is fixedly connected with damping springs 16, and the damping springs 16 are fixedly connected with the slider 17. When the protective plate 4 is impacted by an external force, in addition to the buffering effect of the damping springs 16 and the damper 20, the second inclined rod 18 will also rotate to further disperse the impact force, thereby better protecting the floating plate 1 and the entire aquaculture device from serious damage. The outer wall of the floating plate 1 is fixedly connected with evenly distributed second connecting blocks 19. The outer wall of the second connecting blocks 19 is rotatably connected with the second inclined rod 18, and the second inclined rod 18 is rotatably connected with the slider 17. The two ends of the fixed plate 14 are fixedly connected with dampers 20, and the two dampers 20 are fixed to the protective plate 4 and the floating plate 1 respectively.
[0037] Working Principle: When the oyster raft aquaculture device is in operation, the wind turbine 3 rotates under the action of sea breeze, generating electrical energy which is stored in the battery 7 and powers the motor 8. The motor 8 drives the lead screw 21 to rotate, which in turn drives the nut pair 22 and the moving seat 23 to move up and down along the guide column 9. The connecting column 24 causes the sliding sleeve 25 to move synchronously within the connecting sleeve 2 and the floating plate 1, and the second filter sleeve 11 moves up and down accordingly. When the second filter sleeve 11 moves upward, seawater enters the sliding sleeve 25 after being filtered by the first filter sleeve 10, providing food for the cultured oysters. When the second filter sleeve 11 moves downward, it separates from the first filter sleeve 10, which filters impurities from the seawater, preventing impurities from entering the sliding sleeve 25 and contaminating the oyster growth environment. When the protective plate 4 is impacted by external force, the first inclined rod 12 pushes the slider 17 to slide within the groove 15. The damping spring 16 and the damper 20 provide a buffering effect, while the second inclined rod 18 rotates to further disperse the impact force, protecting the floating plate 1 and the aquaculture device.
