Description

Technical Field

[0001] This invention relates to the field of aquaculture technology for the thick-lipped barb, and more particularly to aquaculture equipment and method for the thick-lipped barb. Background Technology

[0002] The thick-lipped naked carp, a cold-water fish species unique to my country's plateau, has both ecological conservation value and economic development potential. Its growth requires strict aquatic environment conditions, needing to survive in clear, low-turbidity, and oxygen-rich flowing water. In recent years, affected by factors such as habitat degradation and overfishing, the wild population of this fish species has sharply declined, and artificial breeding has become the core approach for species protection and sustainable resource utilization.

[0003] Current equipment for farming *Gymnocypris thunbergii* suffers from technical shortcomings. Traditional filtration devices often employ a single filter structure, which cannot effectively filter impurities of different particle sizes, such as uneaten feed, feces, and algae debris, in the aquaculture water. Large particles easily clog the filter, causing a sharp drop in filtration efficiency, while small particles accumulate with the water flow, increasing turbidity. This not only interferes with fish feeding but also easily breeds harmful microorganisms, increasing the risk of disease and failing to meet the clean water requirements of *Gymnocypris thunbergii*. Furthermore, some equipment lacks anti-backflow and efficient water flow guidance structures, leading to problems such as impurities flowing back into the water and uneven dissolved oxygen distribution in the aquaculture area. In addition, existing aquaculture equipment lacks functional synergy and ease of maintenance. Most equipment lacks an automatic cleaning mechanism, and the filtered impurities clog the filter holes, requiring frequent manual disassembly and cleaning. This is not only time-consuming and labor-intensive but also necessitates suspending the aquaculture system, causing drastic fluctuations in water flow rate and dissolved oxygen concentration, resulting in stress reactions for the environmentally sensitive *Gymnocypris thunbergii*. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a breeding equipment and method for the thick-lipped naked carp. It is a special breeding equipment that integrates high-efficiency filtration, automatic cleaning, stable circulation and adaptive floating functions.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A breeding device for the thick-lipped naked carp includes an impurity filtration and storage mechanism. An upper cover plate is fixedly connected to the upper middle part of the impurity filtration and storage mechanism. A dual-head motor is fixedly connected to the upper middle part of the upper cover plate. A rotating rod is fixedly connected to the lower output end of the dual-head motor. A rotating filter collection mechanism is fixedly connected to the end of the rotating rod away from the dual-head motor. Two linkage scraping and cleaning mechanisms are fixedly connected to the upper output end of the dual-head motor. A floating mechanism is fixedly connected to the lower side of the impurity filtration and storage mechanism.

[0007] The impurity filtration and storage mechanism includes a receiving ring groove, a toothed ring fixedly connected to the upper outer inner wall of the receiving ring groove, and a limiting anti-detachment ring fixedly connected to the upper outer side of the receiving ring groove. The lower side of the receiving ring groove is evenly provided with multiple secondary filter holes, and the inner wall of the receiving ring groove is evenly provided with multiple main filter holes.

[0008] Furthermore, a sleeve is fitted around the outside of the rotating rod, and guide arc plates are fixedly connected to both sides of the outer wall of the sleeve. The positions of the two guide arc plates are symmetrical to each other. Scraper strips are fixedly connected to the lower side of the two guide arc plates. The scraper strips are made of high-density silicone. The ends of the two guide arc plates away from the sleeve are fixedly connected to the inner wall of the mounting ring groove.

[0009] Furthermore, the rotating filter collection mechanism includes a fixed block fixedly connected to the end of the rotating rod away from the dual-head motor, a turntable fixedly connected to the upper outer wall of the fixed block, and a positioning rod fixedly connected to the lower end of the fixed block. Both ends of the positioning rod are fixedly connected to water-filling guide buckets. The positions of the two water-filling guide buckets are centrally symmetrical to each other. The upper sides of the two water-filling guide buckets are fixedly connected to the lower side of the turntable. Two water inlets are opened through the upper side of the turntable. The positions of the two water inlets correspond to the positions of the two water-filling guide buckets, respectively.

[0010] Furthermore, a filter screen is fixedly connected to the inner wall of the two water-guiding buckets at the end away from the water inlet, and an anti-backflow plate is hinged to the upper side of the inner wall of the two water inlets at the end near the positioning rod. The turntable is located in the lower middle part of the receiving ring groove.

[0011] Furthermore, the linkage scraping mechanism includes a fixed arm fixedly connected to the upper output end of the dual-head motor, a rotating column rotatably connected to the lower side of the fixed arm away from the dual-head motor, and a rotating scraper fixedly connected to the rotating column away from the fixed arm. A gear is fixedly connected to the outer wall of the middle part of the rotating column, and the outer wall of the gear meshes with the inner wall of the gear ring.

[0012] Furthermore, the positions of the two linked scraping mechanisms are mirror images of each other, the lower sides of the two scraper blades are in close contact with the upper side of the turntable, and the lower side of the rotating scraper is in close contact with the inner bottom wall of the mounting ring groove.

[0013] Furthermore, the floating mechanism includes multiple fixed members uniformly and fixedly connected to the lower side of the mounting ring groove and the same hollow floating ring fixedly connected to the multiple fixed members on the side away from the mounting ring groove. Multiple water-dispelling plates are uniformly and fixedly connected to the lower side of the hollow floating ring.

[0014] Furthermore, the position height of the hollow floating ring corresponds to the position height of the positioning rod, the gear and the rotating scraper are both set between the limiting anti-detachment ring and the secondary filter hole, and the rotating column is set between the upper cover plate and the limiting anti-detachment ring;

[0015] Furthermore, through the collaborative operation of various institutions, the stringent requirements of the thick-lipped naked carp for clear, oxygen-rich water can be met.

[0016] After the equipment is started, the dual-head motor in the middle of the upper cover plate serves as the core power source, synchronously driving the upper and lower output ends to operate. The lower output end drives the rotating rod to rotate, providing power for the rotating filter collection mechanism. The upper output end drives the fixed arms of the two linkage scraping mechanisms to make circular motion, forming a power transmission system with dual-axis drive and multi-component linkage, ensuring that each functional module responds synchronously.

[0017] The aquaculture water flows naturally into the receiving ring tank of the impurity filtration and storage mechanism through the water flow around the equipment. The main filter holes, which are evenly distributed on the inner wall of the receiving ring tank, play their role first. Their pore size is adapted to the interception requirements of large particles in the aquaculture water of the thick-lipped naked carp. Large particles are blocked inside the receiving ring tank, and the water is initially purified through the main filter holes to prevent large particles from entering the subsequent circulation and causing blockage. The water that has been initially filtered by the main filter holes flows further to the secondary filter holes on the lower side of the receiving ring tank. The pore size of the secondary filter holes is smaller than that of the main filter holes, and it performs secondary interception of small particles in the water. This achieves a layered filtration effect of intercepting large particles through the main filter holes and separating small particles through the secondary filter holes, ensuring that the turbidity of the water that finally enters the aquaculture area meets the survival standards of the thick-lipped naked carp.

[0018] When the upper linkage scraping mechanism operates with the output end of the dual-head motor, it exhibits both revolution and rotation. The fixed arm drives the rotating column, gear, and rotating scraper to make a circular motion around the dual-head motor, covering the entire area of ​​the bottom wall of the mounting ring groove. The gear in the middle of the rotating column meshes with the toothed ring on the upper inner wall of the mounting ring groove. When the gear revolves with the fixed arm, the teeth of the toothed ring generate a reaction force on the gear, driving the gear to drive the rotating column and rotating scraper to rotate. The lower side of the rotating scraper is in close contact with the bottom wall of the mounting ring groove. Its combined revolution and rotation can efficiently scrape away large particles of impurities deposited at the bottom of the ring groove, pushing the impurities to the middle of the ring groove, making it easier for the rotating collection and filtration mechanism to collect them further.

[0019] The present invention has the following beneficial effects:

[0020] 1. In this invention, the impurity filtration and storage mechanism, dual-head motor, rotating rod, and rotating filter collection mechanism work together to alleviate the technical shortcomings of current thick-lipped naked carp farming equipment. Traditional filtration devices mostly use a single filter screen structure, which cannot effectively filter impurities of different particle sizes such as uneaten feed, feces, and algae debris in the farming water. Large particles of impurities easily clog the filter screen, causing a sharp drop in filtration efficiency, while small particles of impurities accumulate with the water flow, causing the water turbidity to increase. This not only interferes with fish feeding but also easily breeds harmful microorganisms, increasing the risk of disease. It is difficult to meet the clean water quality requirements of thick-lipped naked carp. In addition, some equipment does not have anti-backflow and efficient water flow guidance structures, which can easily lead to problems such as impurity backflow and uneven dissolved oxygen distribution in the farming area.

[0021] 2. In this invention, the combination of the top cover plate, scraper, linkage scraping and cleaning mechanism, sleeve and guide arc plate alleviates the lack of functional coordination and maintenance convenience of existing aquaculture equipment. Most equipment lacks an automatic cleaning mechanism, and the impurities filtered will clog the filter holes, requiring frequent manual disassembly and cleaning. This is not only time-consuming and labor-intensive, but also requires the aquaculture system to be suspended, resulting in drastic fluctuations in water flow rate and dissolved oxygen concentration, causing stress reactions in the highly environmentally sensitive thick-lipped naked carp.

[0036] The technical solutions of 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.

[0037] Reference Figure 1-12 An embodiment of the present invention provides a breeding device for thick-lipped naked carp, including an impurity filtration and storage mechanism 1. An upper cover plate 2 is fixedly connected to the upper middle part of the impurity filtration and storage mechanism 1. A double-headed motor 3 is fixedly connected to the upper middle part of the upper cover plate 2. A rotating rod 4 is fixedly connected to the lower output end of the double-headed motor 3. A rotating filter collection mechanism 6 is fixedly connected to the end of the rotating rod 4 away from the double-headed motor 3. Two linkage scraping and cleaning mechanisms 7 are fixedly connected to the upper output end of the double-headed motor 3. A floating mechanism 8 is fixedly connected to the lower side of the impurity filtration and storage mechanism 1.

[0038] The impurity filtration and storage mechanism 1 includes a receiving ring groove 11, a toothed ring 14 fixedly connected to the upper outer inner wall of the receiving ring groove 11, and a limiting anti-detachment ring 15 fixedly connected to the upper outer side of the receiving ring groove 11. A plurality of secondary filter holes 12 are evenly opened on the lower side of the receiving ring groove 11, and a plurality of main filter holes 13 are evenly opened on the inner wall of the receiving ring groove 11.

[0039] A sleeve 9 is fitted around the outside of the rotating rod 4. Guide arc plates 10 are fixedly connected to both sides of the outer wall of the sleeve 9. The positions of the two guide arc plates 10 are symmetrical. Scraper strips 5 are fixedly connected to the lower side of each guide arc plate 10. The scraper strips 5 are made of high-density silicone. The arc-shaped structure of the guide arc plates 10 guides the water containing impurities in the rotating disc 62 to the receiving ring groove 11 for filtration, improving the impurity collection efficiency of the equipment and preventing impurities from accumulating on the upper side of the rotating filter collection mechanism 6. The high-density silicone scraper strips 5 are fixed to the lower side of the guide arc plates 10, and the lower side of the scraper strips 5 is in close contact with the upper side of the rotating disc 62 of the rotating filter collection mechanism 6. During the rotation of the rotating filter collection mechanism 6, the scraper strips 5 can scrape the disc 62 in real time. 2. Adhesive impurities attached to the surface, such as algal mucus and fine particles, are prevented from accumulating and ensure smooth water flow into the water guide hopper 64. At the same time, impurities are prevented from hardening on the surface of the turntable 62 and becoming difficult to clean. The ends of the two guide arc plates 10 away from the sleeve 9 are fixedly connected to the inner wall of the receiving ring groove 11. The guide arc plates 10 not only have the function of collecting impurities, but their symmetrically distributed arc structure can also guide the water to form a spiral upward and radially diffused water flow trajectory. The rotating guide arc plates 10 push the purified water in the receiving ring groove 11 outward. The water flowing out through the main filter hole 13 and the secondary filter hole 12 forms a circulating flow around the equipment, driving the water in the aquaculture area to flow and avoiding uneven dissolved oxygen caused by local water stasis.

[0040] The rotating filter collection mechanism 6 includes a fixed block 61 fixedly connected to the end of the rotating rod 4 away from the dual-head motor 3, a turntable 62 fixedly connected to the upper outer wall of the fixed block 61, and a positioning rod 63 fixedly connected to the lower end of the fixed block 61. Water guide buckets 64 are fixedly connected to the outer walls of both ends of the positioning rod 63. The positions of the two water guide buckets 64 are symmetrical to each other. The upper side of the two water guide buckets 64 is fixedly connected to the lower side of the turntable 62. Two water inlets 66 are opened through the upper side of the turntable 62. The positions of the two water inlets 66 correspond to the positions of the two water guide buckets 64.

[0041] Each of the two water-guiding buckets 64 has a filter screen 65 fixedly connected to the inner wall of the end away from the water inlet 66. Each of the two water inlets 66 has an anti-backflow plate 67 hinged to the upper side of the inner wall of the end near the positioning rod 63. The turntable 62 is located in the lower middle of the receiving ring groove 11. The anti-backflow plate 67 of the rotating filter collection mechanism 6 and the filter screen 65 of the water-guiding bucket 64 form a double anti-backflow barrier. The anti-backflow plate 67 closes automatically by gravity, blocking impurities from flowing back from the water inlet 66. The filter screen 65 directly intercepts impurities in the bucket, preventing impurities from overflowing with the water flow, ensuring that the filtered water remains clean, and preventing the collected impurities from causing secondary pollution of the water.

[0042] The linkage scraping mechanism 7 includes a fixed arm 71 fixedly connected to the upper output end of the dual-head motor 3, a rotating column 72 rotatably connected to the lower side of the fixed arm 71 away from the dual-head motor 3, and a rotating scraper 74 fixedly connected to the rotating column 72 away from the fixed arm 71. A gear 73 is fixedly connected to the outer wall of the middle part of the rotating column 72, and the outer wall of the gear 73 meshes with the inner wall of the gear ring 14.

[0043] The positions of the two linked scraping mechanisms 7 are mirror images of each other, with the lower sides of the two scraper blades 5 closely attached to the upper side of the turntable 62, and the lower side of the rotating scraper 74 closely attached to the inner bottom wall of the mounting ring groove 11.

[0044] The floating mechanism 8 includes multiple fixed members 81 that are uniformly fixedly connected to the lower side of the mounting ring groove 11 and a single hollow floating ring 82 that is fixedly connected to the multiple fixed members 81 on the side away from the mounting ring groove 11. Multiple water-dispelling plates 83 are uniformly fixedly connected to the lower side of the hollow floating ring 82.

[0045] The position height of the hollow floating ring 82 corresponds to the position height of the positioning rod 63. The gear 73 and the rotating scraper 74 are both set between the limiting anti-detachment ring 15 and the secondary filter hole 12. The rotating column 72 is set between the upper cover plate 2 and the limiting anti-detachment ring 15. The floating mechanism 8 on the lower side of the impurity filtration and storage mechanism 1 provides stable buoyancy support for the equipment. Multiple fasteners 81 firmly connect the hollow floating ring 82 to the receiving ring groove 11. The buoyancy of the hollow floating ring 82 allows the entire equipment to float on the surface of the aquaculture water, and its position height corresponds to the positioning rod 63, ensuring that the rotating filter collection mechanism 6 is always in the impurity enrichment area in the lower part of the water, improving the impurity collection efficiency. At the same time, the water-distributing plates 83 evenly distributed on the lower side of the hollow floating ring 82 can offset some of the external force when the water flow impacts or the equipment shakes slightly, reducing the shaking amplitude of the equipment and preventing the equipment from tilting due to water fluctuations, thus ensuring the stable operation of the filtration and cleaning functions.

[0046] Through the collaborative efforts of various institutions, the stringent requirements of the Thick-lipped Barkfish for clear, oxygen-rich water were met.

[0047] After the equipment is started, the dual-head motor 3 in the middle of the upper cover plate 2 serves as the core power source, synchronously driving the upper and lower output ends to operate. The lower output end drives the rotating rod 4 to rotate, providing power for the rotating filter collection mechanism 6. The upper output end drives the fixed arms 71 of the two linkage scraping mechanisms 7 to perform circular motion, forming a power transmission system with dual-axis drive and multi-component linkage, ensuring that each functional module responds synchronously.

[0048] The aquaculture water flows naturally into the receiving ring trough 11 of the impurity filtration and storage mechanism 1 through the water flow around the equipment. The main filter holes 13, which are evenly opened on the inner wall of the receiving ring trough 11, play a role first. Their pore size is adapted to the interception requirements of large particles in the aquaculture water of the thick-lipped naked carp. The large particles are blocked inside the receiving ring trough 11, and the water is initially purified through the main filter holes 13 to prevent large particles from entering the subsequent circulation and causing blockage. The water that has been initially filtered by the main filter holes 13 flows further to the secondary filter holes 12 on the lower side of the receiving ring trough 11. The pore size of the secondary filter holes 12 is smaller than that of the main filter holes 13, and the small particles in the water are intercepted for a second time. This achieves a layered filtration effect of intercepting large particles by the main filter holes 13 and separating small particles by the secondary filter holes 12, ensuring that the turbidity of the water that finally enters the aquaculture area meets the survival standards of the thick-lipped naked carp.

[0049] When the upper linkage scraping mechanism 7 operates with the output end of the dual-head motor 3, it exhibits both revolution and rotation. The fixed arm 71 drives the rotating column 72, gear 73, and rotating scraper 74 to perform circular motion around the dual-head motor 3, covering the entire area of ​​the inner bottom wall of the mounting ring groove 11. The gear 73 in the middle of the rotating column 72 meshes with the toothed ring 14 on the upper inner wall of the mounting ring groove 11. When the gear 73 revolves with the fixed arm 71, the teeth of the toothed ring 14 generate a reaction force on the gear 73, driving the gear 73 to drive the rotating column 72 and rotating scraper 74 to rotate. The lower side of the rotating scraper 74 is in close contact with the inner bottom wall of the mounting ring groove 11. Its combined revolution and rotation can efficiently scrape away large particles of impurities deposited at the bottom of the ring groove, pushing the impurities to the middle of the ring groove, making it easier for the rotating collection and filtration mechanism 6 to collect them further.

[0050] Working Principle: This aquaculture equipment uses layered filtration, automatic cleaning, stable circulation, and adaptive floating as its core logic. Through the coordinated operation of various mechanisms, it meets the stringent requirements of the thick-lipped naked carp for clear, oxygen-rich water. After the equipment starts, the dual-head motor 3 in the middle of the upper cover plate 2 serves as the core power source, synchronously driving the upper and lower output ends. The lower output end drives the rotating rod 4 to rotate, providing power for the rotating filter collection mechanism 6. The upper output end drives the fixed arms 71 of the two linked scraping mechanisms 7 to perform circular motion, forming a power transmission system with dual-axis drive and multi-component linkage, ensuring that each functional module responds synchronously. The aquaculture water naturally flows into the receiving ring groove 11 of the impurity filtration and storage mechanism 1 through the water flow around the equipment. The main filter holes 1 are evenly opened on the inner wall of the receiving ring groove 11. 3. First, it functions by using a pore size adapted to the interception requirements of large particles in the water used for raising *Gymnocypris thunbergii*. Large particles are blocked inside the receiving ring trough 11, while the water undergoes preliminary purification through the main filter holes 13, preventing large particles from entering subsequent circulation and causing blockages. The water, after preliminary filtration through the main filter holes 13, flows further to the secondary filter holes 12 below the receiving ring trough 11. The secondary filter holes 12 have a smaller pore size than the main filter holes 13, further intercepting small particles in the water. This achieves a layered filtration effect, where large particles are intercepted by the main filter holes 13 and small particles are separated by the secondary filter holes 12. This ensures that the turbidity of the water entering the aquaculture area meets the survival standards for *Gymnocypris thunbergii*. The rotating rod 4 rotates, causing the rotating filter collection mechanism 6 at the lower end to operate synchronously. The water guide buckets 64 at both ends of the positioning rod 63 follow the rotation. The rotating rod 4 performs a circular motion, and its bucket-shaped structure, combined with centrifugal force, guides water from the aquaculture area into the bucket. The filter screen 65 at the end of the water guide bucket 64 away from the inlet 66 protects the fish and prevents them from accidentally entering the equipment. The anti-backflow plate 67 on the upper side of the turntable 62, corresponding to the inlet 66, can automatically open under the impact of water flow. Water carrying small impurities enters the water guide bucket 64 through the inlet 66. When the water pressure decreases, the anti-backflow plate 67 automatically closes due to gravity, completely blocking the backflow path of impurities and ensuring that impurities are stably stored in the water guide bucket 64. At the same time, the rotating rod 4 drives the turntable 62 to rotate, and the arc-shaped structure of the guide arc plate 10 can guide the water containing impurities in the turntable 62 to flow to the receiving ring groove 11 for filtration, improving the efficiency of the equipment. To improve impurity collection efficiency and prevent impurities from accumulating on the upper side of the rotating filter collection mechanism 6, a high-density silicone scraper 5 is fixed to the lower side of the guide arc plate 10. The lower side of the scraper 5 is in close contact with the upper side of the turntable 62 of the rotating filter collection mechanism 6. During the rotation of the rotating filter collection mechanism 6, the scraper 5 can scrape off the sticky impurities, such as algae slime and fine particles, attached to the surface of the turntable 62 in real time, preventing impurity accumulation and ensuring smooth water flow into the water filling guide hopper 64. At the same time, it prevents impurities from hardening and becoming difficult to clean on the surface of the turntable 62. When the upper linkage scraping and cleaning mechanism 7 operates with the output end of the double-head motor 3, it exhibits both revolution and rotation. The fixed arm 71 drives the rotating column 72, gear 73 and rotating scraper 74 to perform circumferential motion around the double-head motor 3, covering the entire area of ​​the inner bottom wall of the mounting ring groove 11.The gear 73 in the middle of the rotating column 72 meshes with the toothed ring 14 on the upper inner wall of the mounting ring groove 11. When the gear 73 revolves with the fixed arm 71, the teeth of the toothed ring 14 generate a reaction force on the gear 73, driving the gear 73 to rotate the rotating column 72 and the rotating scraper 74. The lower side of the rotating scraper 74 is in close contact with the inner bottom wall of the mounting ring groove 11. Its combined motion of revolution and rotation can efficiently scrape off large particles of impurities deposited at the bottom of the ring groove, pushing the impurities to the middle of the ring groove, making it easier for the rotating collection and filtration mechanism 6 to collect them further. At the same time, the scraping action of the rotating scraper 74 can unclog the blocked main filter holes 13 and secondary filter holes 12, restoring the flow capacity of the filter holes and preventing the filtration efficiency from decreasing due to filter hole blockage. The limiting anti-detachment ring 15 limits the movement of gear 73 and rotating scraper 74, preventing them from deviating from the preset trajectory during operation and ensuring stable and reliable cleaning action. The guide arc plate 10 not only has a debris-gathering function, but its symmetrically distributed arc structure can also guide the water to form a spiral upward and radially diffused water flow trajectory. The rotating guide arc plate 10 pushes the purified water in the receiving ring groove 11 outward. The water flowing out through the main filter hole 13 and secondary filter hole 12 forms a circulating flow around the equipment, driving the water flow in the aquaculture area and avoiding uneven dissolved oxygen caused by local water stasis. At the same time, the circulating water movement can bring oxygen from the air into the water, increasing the dissolved oxygen concentration of the aquaculture water and meeting the requirements of thick-lipped bare-lipped heavy-lipped Fish require a high dissolved oxygen environment. The anti-backflow plate 67 of the rotating filtration mechanism 6 and the filter screen 65 of the water guide hopper 64 form a double anti-backflow barrier. The anti-backflow plate 67 closes automatically by gravity, preventing impurities from flowing back into the inlet 66. The filter screen 65 directly traps impurities in the hopper, preventing them from overflowing with the water flow and ensuring that the filtered water remains clean. This prevents secondary pollution of the water by the collected impurities. The floating mechanism 8 on the lower side of the impurity filtration and storage mechanism 1 provides stable buoyancy support for the equipment. Multiple fasteners 81 firmly connect the hollow floating ring 82 to the receiving ring groove 11. The buoyancy of the hollow floating ring 82 allows the entire equipment to float on the surface of the aquaculture water, and its position height corresponds to the positioning rod 63. The rotating filter collection mechanism 6 is always positioned in the impurity-rich zone in the lower part of the water body, improving impurity collection efficiency. Simultaneously, the evenly distributed water-dispersing plates 83 on the lower side of the hollow floating ring 82 can offset some external forces when water flows or the equipment shakes slightly, reducing the amplitude of equipment swaying and preventing tilting due to water fluctuations. This ensures stable operation of the filtration and cleaning functions. In summary, through the synergistic operation of layered filtration to intercept impurities, automatic cleaning to prevent clogging, circulating water flow to increase dissolved oxygen, and the floating structure to maintain stability, the equipment continuously provides a water environment that meets the survival standards for the Thick-lipped Barbet, while reducing the frequency of manual maintenance, avoiding water fluctuations caused by equipment shutdown for cleaning, and reducing the risk of stress reactions in the fish.

9. A method for cultivating the thick-lipped naked carp, characterized in that, The equipment for raising thick-lipped naked carp according to any one of claims 1-8 includes: meeting the stringent requirements of thick-lipped naked carp for clear, oxygen-rich water through the coordinated operation of various mechanisms; After the equipment is started, the double-headed motor (3) in the middle of the upper cover plate (2) serves as the core power source, synchronously driving the upper and lower output ends to operate. The lower output end drives the rotating rod (4) to rotate, providing power for the rotating filter collection mechanism (6). The upper output end drives the fixed arms (71) of the two linkage scraping mechanisms (7) to make circular motion, forming a power transmission system with upper and lower dual-axis drive and multi-component linkage, ensuring that each functional module responds synchronously. The aquaculture water flows naturally into the impurity filtration and storage mechanism (1) through the surrounding water flow. The main filter holes (13) evenly opened on the inner wall of the main filter hole (11) play a role first. The hole diameter is adapted to the interception requirements of large particles of impurities in the aquaculture water of the thick-lipped naked carp. The large particles of impurities are blocked inside the main filter hole (11), and the water is initially purified through the main filter hole (13) to avoid large particles of impurities entering the subsequent circulation and causing blockage. The water that has been initially filtered by the main filter hole (13) flows further to the secondary filter hole (12) on the lower side of the main filter hole (11). The hole diameter of the secondary filter hole (12) is smaller than that of the main filter hole (13), and the small particles of impurities in the water are intercepted for a second time. This achieves the layered filtration effect of interception of large particles by the main filter hole (13) and separation of small particles by the secondary filter hole (12), ensuring that the turbidity of the water that finally enters the aquaculture area meets the survival standards of the thick-lipped naked carp. When the upper linkage scraping mechanism (7) operates with the upper output end of the dual-head motor (3), it exhibits both revolution and rotation. The fixed arm (71) drives the rotating column (72), gear (73) and rotating scraper (74) to make circular motion around the dual-head motor (3), covering the entire area of ​​the bottom wall of the mounting ring groove (11). The gear (73) in the middle of the rotating column (72) meshes with the gear ring (14) on the upper inner wall of the mounting ring groove (11). When the gear... (73) When the fixed arm (71) revolves, the teeth of the toothed ring (14) generate a reaction force on the gear (73), driving the gear (73) to drive the rotating column (72) and the rotating scraper (74) to rotate. The lower side of the rotating scraper (74) is in close contact with the inner bottom wall of the mounting ring groove (11). Its combined motion of revolution and rotation can efficiently scrape off large particles of impurities deposited at the bottom of the ring groove and push the impurities to the middle of the ring groove, making it easier for the rotating filter collection mechanism (6) to collect them further.
