[0002] As a unique and distinctive aquatic product in my country, the yellow eel is highly favored by consumers for its nutritional characteristics, including high protein, low fat, rich unsaturated fatty acids, and various minerals. Market demand has maintained a steady growth trend year after year. In recent years, with the initial popularization of aquaculture technology and driven by market dividends, yellow eel farming has broken through the geographical limitations of the traditional middle and lower reaches of the Yangtze River and has rapidly spread to many regions such as North China, South China, and Southwest China, forming a nationwide aquaculture layout.

[0003] Existing eco-friendly and efficient eel farming equipment has significant shortcomings in practical applications. Its water flow regulation lacks a flexible and controllable operating mechanism, making it difficult to accurately adjust the water circulation speed according to farming needs. The water purification effect is unsatisfactory, failing to fully meet the requirements of eels for a high-quality water environment. At the same time, the disassembly and maintenance process of key components such as filters is cumbersome, which not only increases the workload of farming management but also affects the overall efficiency of the equipment, thus hindering the ecological and efficient development of eel farming.

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an eco-efficient eel farming device, comprising a farming pond 1, a purification zone 3 on the front inner wall of the farming pond 1, a farming zone 2 on the rear inner wall of the farming pond 1, a habitat layer 25 fixedly connected to both the left and right sides of the inner wall of the farming zone 2, a protective box 4 fixedly connected to the top right side of the farming pond 1, a rotating wheel 5 rotatably connected to the outer right side of the protective box 4, a worm gear 6 fixedly connected to the left end of the rotating wheel 5, a worm wheel 7 meshing with the outer wall of the worm gear 6, a rotating rod 8 fixedly connected to the inner wall of the worm wheel 7, a gear 9 fixedly connected to the inner wall of the rotating rod 8, an opening and closing door 10 provided on the inner wall of the farming zone 2, a rack 11 fixedly connected to the top right side of the opening and closing door 10, the rack 11 meshing with the gear 9, the outer wall of the rotating rod 8 rotatably connected to the inner wall of the protective box 4, and the left end of the worm gear 6 rotatably connected to the inner wall of the protective box 4.

[0019] Specifically, the breeding pond 1, purification area 3, and breeding area 2 are integrated into one unit, serving as independent spaces for eel breeding and water purification. Breeding area 2 is designed in a terraced shape to facilitate water flow and allow impurities to flow out from the rear during cleaning, improving space utilization and ease of cleaning. The habitat layer 25 is used for eel habitat and nest building. The breeding pond 1 is fixed with a protective box 4, providing protection and installation support for transmission components such as the worm gear 6 and worm wheel 7, preventing damage to the components. The manual rotation of the rotating wheel 5 provides an operating input for the transmission system, facilitating control of the opening and closing of the door 10. The worm gear 6 rotates synchronously with the rotating wheel 5, transmitting the manual rotational force to the worm gear 7, thus providing power for the rotation of the worm gear 7. The direction of power transmission is changed, causing the rotating rod 8 to rotate. The rotating rod 8 transmits the rotational power of the worm gear 7, causing the rotating rod 8 to rotate synchronously, providing rotational power to the gear 9. The gear 9 rotates synchronously with the rotating rod 8. Through the meshing of the gear 9 and the rack 11, the rotational motion is converted into the lifting motion of the rack 11. The rack 11 transmits the rotational power of the gear 9, causing the rack 11 to move up and down, thereby controlling the lifting and lowering of the opening and closing gate 10 to adjust the water flow rate. The opening and closing gate 10 rises and falls synchronously with the rack 11. The degree of opening and closing of the opening and closing gate 10 controls the water flow between the breeding area 2 and the purification area 3, and adjusts the water circulation speed. The water flow rate can be controlled by adjusting the opening and closing gate 10, and the water circulation speed can be flexibly adjusted.

[0020] Reference Figures 1-3 The top inner wall of the purification zone 3 is equipped with an emergent plant layer 12, and the bottom inner wall of the purification zone 3 is equipped with a biological filter media layer 13. The front outer wall of the aquaculture pond 1 is equipped with a Roots blower 14. The inner wall of the Roots blower 14 is fixedly connected to an aeration main pipe 15. Multiple aeration branch pipes 16 are fixedly connected to the outer walls of both sides of the aeration main pipe 15. Several aeration holes are opened at the top of each aeration branch pipe 16. The outer walls of the aeration main pipe 15 and the aeration branch pipes 16 are fixedly connected to the inner wall of the purification zone 3.

[0021] Specifically, the emergent plant layer 12 is planted with plants such as water hyacinth, whose roots absorb nutrients such as nitrogen and phosphorus from the water, while also blocking sunlight, inhibiting algae growth, and improving the aquatic environment. The biological filter media layer 13 has beneficial microorganisms such as nitrifying bacteria and photosynthetic bacteria attached to the surface of the filter media, which decompose ammonia nitrogen and nitrite to purify the water. The aquaculture pond 1 has a fixed Roots blower 14 to provide a stable air source for the aeration components, ensuring continuous aeration. The air generated by the Roots blower 14 is delivered to the main aeration pipe 15 to provide a gas source for the aeration branch pipes 16. The aeration branch pipes 16 distribute the air evenly and release bubbles through the top aeration holes. The aeration components are fixed at the bottom of the biological filter media layer 13, continuously aerating to increase the dissolved oxygen content of the water, promote the activity of beneficial microorganisms, and enhance the water purification effect.

[0022] Reference Figure 1 , Figure 5 and Figure 6 The top left and right sides of the breeding pond 1 are equipped with fixing components. The front inner wall of the breeding area 2 is equipped with an installation frame 17. The fixing components include installation blocks 21 fixedly connected to the top left and right sides of the breeding pond 1. The inner wall of the installation block 21 is slidably connected with a slide rod 22. The outer wall of the slide rod 22 is fixedly connected with a slide plate 23. The inner wall of the installation block 21 is equipped with a spring 24. The rear end of the spring 24 is connected to the front outer wall of the slide plate 23. The front end of the spring 24 is connected to the inner wall of the installation block 21. The outer wall of the slide plate 23 is slidably connected to the inner wall of the installation block 21. The rear inner wall of the installation frame 17 is fixedly connected with a filter screen 18. The front inner wall of the installation frame 17 is fixedly connected with an activated carbon adsorption layer 19. The top left and right sides of the installation frame 17 are fixedly connected with a locking block 20. The inner wall of the locking block 20 is provided with a through hole. The size of the through hole is adapted to the slide rod 22.

[0023] Specifically, the fixed mounting block 21 of the aquaculture pond 1 provides installation support for components such as the sliding rod 22 and spring 24, establishing a stable foundation for the fixed components. The sliding rod 22 can slide along the inner wall of the mounting block 21, facilitating insertion or removal from the through hole of the locking block 20, thereby fixing and unlocking the mounting frame 17. The sliding rod 22 drives the sliding plate 23 to slide synchronously, transmitting the elastic force of the spring 24 to ensure smooth movement of the sliding rod 22. The mounting block 21 fixes the front fulcrum of the spring 24, providing stable support for the deformation and reset of the spring 24. Utilizing the elastic force of the spring 24, which is greater than the frictional force of the sliding rod 22, the sliding plate 23 is pushed, causing the sliding rod 22 to automatically insert into the through hole of the locking block 20, firmly fixing the mounting frame 17. The cooperation between the locking block 20 and the sliding rod 22 facilitates the quick assembly and disassembly of the mounting frame 17, making it convenient for cleaning or replacing internal components. The system includes a filter screen 18, which filters solid impurities in the water of the aquaculture area 2 to prevent blockage of the flow channel and ensure smooth water flow. It also prevents eels from entering the purification area 3. The activated carbon adsorption layer 19 adsorbs odors and harmful chemicals in the water, further purifying the water quality and optimizing the eel's growth environment. The locking block 20 provides a locking structure that matches the slide rod 22. The through hole allows for precise docking between the mounting frame 17 and the fixing component. The through hole provides insertion space for the slide rod 22, and the matching size of the slide rod 22 ensures a secure lock, preventing the mounting frame 17 from loosening during use. The cooperation of the slide rod 22, spring 24, and locking block 20 enables quick disassembly and installation of the mounting frame 17 and the internal filter screen 18. At the same time, the filter screen 18 filters impurities, the activated carbon adsorption layer 19 purifies the water quality, and the system is securely fixed and easy to maintain.

[0024] Working Principle: After the eels are introduced into breeding area 2, they inhabit and build nests in habitat layer 25. The terraced structure of breeding area 2 ensures smooth water flow and facilitates subsequent impurity removal. Water hyacinth and other plants planted in the emergent plant layer 12 of purification area 3 absorb nutrients such as nitrogen and phosphorus from the water through their roots, while simultaneously blocking sunlight and inhibiting algae growth, thus initially improving the aquatic environment. Beneficial microorganisms such as nitrifying bacteria and photosynthetic bacteria attached to the surface of biological filter layer 13 continuously decompose harmful substances such as ammonia nitrogen and nitrite in the water, achieving initial water purification. The Roots blower 14 is activated, and the generated air is distributed through the aeration main pipe 15 to each aeration branch pipe 16. Bubbles are released through the aeration holes at the top of the branch pipes, continuously aerating the bottom of the biological filter layer 13, increasing dissolved oxygen content, promoting the activity of beneficial microorganisms, and enhancing the water purification effect. Manually rotating the impeller 5 drives the opening and closing of the gate through the transmission system. The lifting mechanism 10 adjusts its opening and closing degree according to the water quality of breeding area 2, flexibly controlling the water flow between breeding area 2 and purification area 3, and achieving precise control of water circulation speed. The mounting frame 17 is fixed by the cooperation of the locking block 20 and the sliding rod 22. The elastic force of the spring 24 is greater than the friction of the sliding rod 22, pushing the sliding rod 22 into the through hole of the locking block 20, ensuring that the mounting frame 17 is stable and does not loosen. During water circulation, the filter screen 18 filters solid impurities in breeding area 2, avoiding blockage of the flow channel and preventing eels from entering purification area 3. The activated carbon adsorption layer 19 adsorbs odors and harmful chemicals in the water, further improving water cleanliness. When cleaning or maintenance is required, the sliding rod 22 is slid to compress the spring 24, and the mounting frame 17 is removed after unlocking. The filter screen 18 and activated carbon adsorption layer 19 can be cleaned and replaced. The impurities accumulated in breeding area 2 flow out along the stepped rear side, completing the cleaning operation and ensuring a stable and clean growth environment for eels throughout the process.
