Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a device for artificially stimulating ocean currents in the breeding of silver pomfret. Background Technology

[0002] Silver pomfret's natural habitat is mostly in slow- to medium-current areas nearshore or offshore. Its growth and development are closely physiologically linked to ocean currents. In recent years, due to overfishing, wild silver pomfret resources have continued to decline, making artificial breeding a core support for resource recovery and the development of the aquaculture industry. Currently, the ultimate goal of artificial breeding of silver pomfret is release for propagation or aquaculture production. However, artificial breeding often uses still water, which can easily lead to the degeneration of swimming ability in juvenile silver pomfret. For example, it can result in weak muscle development and a rounded body shape, making them prone to death during subsequent release or aquaculture due to insufficient predation ability or poor resistance to currents. To improve this situation, it is necessary to change the state of the aquaculture water. The continuous stimulation of simulated ocean currents can promote muscle fiber proliferation and guide silver pomfret to maintain a streamlined body shape, making its morphology and swimming ability closer to wild individuals, fundamentally improving the quality of seedlings. Furthermore, silver pomfret are typical schooling fish, forming orderly schools in the wild guided by ocean currents. In still water, juvenile silver pomfret tend to scatter and even fight among themselves, leading to increased mortality. Simulated ocean currents can guide juveniles to form natural groups and restore their instinctive schooling behavior. However, existing traditional still water or simple flowing water seedling cultivation methods cannot simulate natural ocean currents. Furthermore, although some seedling cultivation methods attempt to optimize feed and water quality, they still rely on static rearing ponds and lack the ability to simulate dynamic ocean currents.

[0003] In response, existing equipment has developed ocean current simulation technologies or specialized seedling cultivation techniques. For example, prior art application number CN202010223921.X discloses a submarine ocean current simulation device. This invention simulates the in-situ deep-sea environment within a high-pressure simulation chamber, realistically simulating the seabed interface, underlying sediments, and overlying water environment. While ensuring the in-situ physical, chemical, and geological conditions of the deep sea, it simulates the formation and evolution of deep-sea currents through a submarine current injection system. During the evolution process, different forms and types of deep-sea currents are simulated using components and parameters built into the environmental condition control unit. However, this ocean current simulation technology is not suitable for seedling cultivation. Another example is prior art WO2019198063A1, which discloses a fish farm including a land-based brine circulation pool supplied by seawater inlets, and efficient water flow and waste removal technologies to promote favorable fish growth conditions. This invention features devices for promoting laminar flow in the circulation pool, devices for effectively removing waste, and multiple seawater inlets from different ocean depths. However, existing seedling cultivation equipment does not yet possess ocean current simulation capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a simulated ocean current stimulation device for artificial breeding of silver pomfret, which can simulate natural ocean currents to adapt to the development and breeding needs of silver pomfret, improve the survival rate, and the invention adopts a water circulation scheme to ensure the water quality requirements for breeding.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: a simulated ocean current stimulation device for artificial seedling cultivation of silver pomfret, comprising: a temporary holding tank, one end of which is an inlet and the other end of which is an outlet; a second tank is provided on one side of the inlet of the temporary holding tank, and at least two water pumps are built into the second tank; the outlet of the water pumps has a drain pipe located above the inlet of the temporary holding tank; a third tank is connected to the outlet of the temporary holding tank. Multiple through holes are provided on the wall of the temporary holding tank, and a water pipe connected to the through holes is provided on the third tank to allow water from the temporary holding tank to enter the third tank.

[0006] This invention utilizes at least two water pumps built into the second tank to ensure stable power, enabling a continuous water supply from the drain pipe to the inlet of the holding tank, forming a water flow that simulates natural ocean currents. This provides the dynamic aquatic environment required for the development of silver pomfret fry, encouraging them to swim actively to strengthen muscle and bone development and reduce the deformity rate. Furthermore, multiple through holes in the walls of the holding tank connect to the water pipes of the third tank, allowing water containing uneaten food and feces to flow into the third tank, preventing the accumulation of pollutants, ensuring clean water and uniform dissolved oxygen in the holding tank, and laying the foundation for subsequent water circulation.

[0007] According to one embodiment of the present invention, the inlet end of the holding tank is provided with a first mesh, and the outlet end of the holding tank is provided with a second mesh. The first mesh at the inlet end of the holding tank can prevent the temporarily held silver pomfret fry from entering the inlet pipe or contacting the flow control components when the water pump in the second tank supplies water to the holding tank through the drain pipe, thus preventing the fry from being swept into the gaps between the components by the water flow and causing damage. At the same time, it does not hinder the formation of a stable simulated ocean current environment. Furthermore, the second mesh at the outlet end of the holding tank can intercept the fry when the water carries uneaten feed and feces through the through holes in the tank wall to the third tank, preventing them from entering the third tank with the water flow and being lost. This ensures that the fry remain in the holding tank's rearing space and does not affect the normal flow of water.

[0008] According to one embodiment of the present invention, a flow control assembly is provided at the inlet end of the temporary holding tank. The flow control assembly includes a first insert plate vertically inserted into the upper end of the temporary holding tank. A crankshaft is provided on one side of the first insert plate. A first drive motor connected to the crankshaft is provided outside the temporary holding tank. A second connecting rod is sequentially connected to the rotating part of the crankshaft. A first connecting rod is rotatably connected to the end of the second connecting rod. A guide plate is connected to the bottom of the first connecting rod. Second connecting rods connected to the crankshaft are sequentially spaced on the side. The flow control assembly is located on one side of the first mesh.

[0009] This invention utilizes a flow control component at the inlet of the temporary holding tank. This allows a first drive motor to power a crankshaft, which in turn rotates. A second connecting rod, spaced apart on the side of the crankshaft, synchronously drives a first connecting rod at its end, thereby guiding the flow plate. This allows for flexible adjustment of the flow rate and direction of the water at the inlet of the temporary holding tank, simulating the dynamic changes of natural ocean currents and adapting to the different developmental stages of silver pomfret fry. Furthermore, a first insert plate is vertically inserted into the upper part of the temporary holding tank, providing stable support for components such as the crankshaft and connecting rods, ensuring the operation of the transmission structure and preventing component misalignment during water flow adjustment. Additionally, the flow control component is located on one side of the first mesh. The water flow adjusted by the flow plate is buffered by the first mesh before entering the holding space, ensuring uniform water diffusion and preventing the seedlings from contacting the moving parts of the flow control component, thus preventing them from being caught and damaged.

[0010] According to one embodiment of the present invention, a support rod corresponding to the position of the second connecting rod is provided below it. One end of the support rod is fixedly connected to the first insert plate, and the other end of the support rod can contact or separate from the first connecting rod. The fixed connection of one end of the support rod to the first insert plate provides support for the upper transmission structure. When the first drive motor drives the crankshaft, the second connecting rod, and the first connecting rod to move to adjust the guide plate, the other end of the support rod can contact the first connecting rod to prevent the first connecting rod from drooping excessively due to its own weight or water flow impact, and to prevent the guide plate from moving out of place due to the displacement of the transmission structure, thus ensuring the water flow adjustment effect and ensuring the stability of the ocean current simulation effect at the inlet of the temporary holding tank. At the same time, the support rod and the first connecting rod are only non-fixedly connected by contact or separation, and the normal rotation and swing of the first connecting rod with the transmission system are not restricted.

[0011] According to one embodiment of the present invention, a filter tank communicating with the second housing is provided on one side, and a first housing communicating with the filter tank on one side. The filter tank contains a water pump for drawing water from the first housing. The water pump in the filter tank actively draws water from the first housing, completing filtration before the water enters the second housing, removing impurities, uneaten food debris, and some harmful microorganisms, preventing pollutants from entering the second housing with the water flow. The first housing, in conjunction with the first pump, provides continuous water supply, the filter tank purifies the water, and the second housing receives the purified water and converts it into ocean current-like power via the water pump.

[0012] According to one embodiment of the present invention, a first pump body is provided on the outside of the third tank and communicates with it. The first pump body is connected to the first tank through a first pipe. The first pump body can pump water from the third tank to the first tank to form a water circulation. The first pump body draws water discharged from the temporary holding tank received in the third tank and transports it to the first tank through the first pipe, realizing the circulation of water through the first tank, filter tank, second tank, temporary holding tank, third tank, and first tank in sequence, avoiding water waste. At the same time, the water can be purified again by the filter tank during the circulation process, reducing the long-term accumulation of pollutants such as uneaten feed and feces in the temporary holding tank. In addition, according to the needs of seedling cultivation, a temperature control device can be built into the first tank or the second tank to regulate the water temperature, thereby controlling the simulated ocean current temperature and achieving a more realistic ocean current simulation effect.

[0013] According to one embodiment of the present invention, an auxiliary component is provided at the outflow end of the holding tank. The auxiliary component includes a second insert plate inserted into the wall of the outflow end of the holding tank. The second insert plate is horizontally arranged with the bottom of the holding tank, and the second insert plates are spaced apart on the wall of the holding tank. Each of the second insert plates has a first opening on its surface. The horizontally arranged and spaced-apart second insert plates can buffer the water flow at the outflow end of the holding tank, preventing the water flow velocity near the outflow end from being too fast and affecting the fish fry in the direction of the outflow end. Furthermore, the first openings on the surface of the second insert plates ensure that the water carrying uneaten food and feces in the holding tank can flow smoothly to the third tank, and can also preliminarily filter some of the larger particles of uneaten food and feces, reducing the entry of pollutants into the subsequent circulation system.

[0014] According to one embodiment of the present invention, two opposing connecting base plates are respectively provided on both sides of the bottom of the second insert plate. A sliding groove is formed on the connecting base plate, and a sliding bent plate connected to the bottom surface of the second insert plate is provided within the sliding groove. Each end of the two connecting base plates is provided with a rotatable rotating plate, which is connected to the other via a swing plate. The sliding groove of the connecting base plate allows the sliding bent plate to slide along the groove, adjusting the relative position of the sliding bent plate and the bottom surface of the second insert plate, thereby controlling the buffer range of the outflow. The rotating plates at the ends of the two connecting base plates can rotate flexibly, driving the connected swing plate to adjust its angle. This guides the direction of the outflow from the temporary holding tank, preventing local water stagnation or sudden changes in flow velocity. Furthermore, the swinging plate helps to move impurities that may settle upwards or in the same direction within the temporary holding tank, thus promoting their discharge and achieving a cleaning effect.

[0015] According to one embodiment of the present invention, a perforated interceptor is connected to the swing plate. The interceptor can be circular, polygonal, or other shapes, and has a perforated structure. The swing plate, connected to the perforated interceptor, allows adjustment of the angle and coverage area of ​​the interceptor to ensure it corresponds to the water flow path at the outlet of the holding tank, adapting to filtration requirements at different flow rates. The perforated structure of the interceptor not only helps intercept impurities but also helps reduce the water flow velocity at the outlet of the holding tank, ensuring smooth water discharge.

[0016] According to one embodiment of the present invention, the holding box has a long, narrow box structure with an opening at the top. There is a space between the inlet and outlet ends of the holding box for the cultured organisms. The elongated structure of the holding tank allows the water pumped by the pump in the second tank to form a continuous and stable flow channel from the inlet to the outlet. Combined with the ocean-like current regulated by the flow control components, it can cover the entire breeding interval space, meeting the swimming needs of silver pomfret seedlings throughout the breeding area and avoiding dead zones in the local water flow. The opening design at the top of the holding tank makes it easy for staff to observe the breeding status and feed the seedlings. The breeding interval space between the inlet and outlet, along with the first mesh at the inlet end, the second mesh at the outlet end, and auxiliary components, can prevent the seedlings from coming into contact with the water or being lost with the water flow.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a flow control component in conjunction with a double water pump in the second tank to dynamically adjust the water flow speed and direction, simulating natural ocean currents, adapting to the water flow requirements of silver pomfret fry at different developmental stages, which can promote active swimming of the seedlings to strengthen muscle and bone development and reduce the deformity rate. The first mesh at the inlet of the temporary rearing tank prevents the seedlings from being damaged by contact with the flow control component, and the second mesh at the outlet prevents the seedlings from being lost with the water. The second insert plate of the auxiliary component buffers the water flow to avoid impacting the seedlings, thus ensuring the safety of the seedlings in all aspects. Attached Figure Description

[0021] 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.

[0022] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1:

[0023] As shown in the attached figure Figure 1 -Appendix Figure 3As shown, the artificial breeding device for silver pomfret using simulated ocean currents includes a temporary holding tank 40, with one end being an inlet and the other an outlet. A second tank 30 is located on one side of the inlet of the temporary holding tank 40, containing at least two water pumps 31. The outlet of each water pump 31 has a drain pipe 32 located above the inlet of the temporary holding tank 41. A third tank 70 is connected to the outlet of the temporary holding tank 40. Multiple through holes are provided on the wall of the temporary holding tank 40, and a water pipe connected to the through holes is provided on the third tank 70 to allow water from the temporary holding tank 40 to enter the third tank 70.

[0024] This invention utilizes at least two water pumps 31 built into the second tank 30 to ensure stable power, enabling the drain pipe 32 to continuously supply water to the inlet of the temporary holding tank 40, forming a water flow that simulates natural ocean currents. This meets the dynamic water environment required for the development of silver pomfret fry, encouraging them to swim actively to strengthen muscle and bone development and reduce the deformity rate. Furthermore, multiple through holes in the wall of the temporary holding tank 40 are connected to the water pipe of the third tank 70, allowing water containing uneaten food and feces in the temporary holding tank 40 to flow into the third tank 70, preventing the accumulation of pollutants, ensuring clean water and uniform dissolved oxygen in the temporary holding tank 40, and providing a basis for subsequent water circulation.

[0025] See appendix Figure 3 The temporary holding tank 40 has a first mesh 42 at its inlet and a second mesh 43 at its outlet. The first mesh 42 at the inlet of the temporary holding tank 40 can prevent the temporarily held silver pomfret fry from entering the inlet pipe or contacting the flow control component 50 when the water pump 31 in the second tank 30 supplies water to the temporary holding tank 40 through the drain pipe 32. This prevents the fry from being swept into the gaps between the components by the water flow and causing damage, while not obstructing the formation of a stable simulated ocean current environment. Furthermore, the second mesh 43 at the outlet of the temporary holding tank 40 can intercept the fry when the water carries uneaten food and feces through the openings in the tank wall to the third tank 70, preventing them from entering the third tank 70 and being lost. This ensures that the fry remain in the rearing space of the temporary holding tank 40 without affecting the normal flow of water.

[0026] See appendix Figure 4 Appendix Figure 5 As shown, the inlet end of the temporary holding tank 40 is equipped with a flow control assembly 50. The flow control assembly 50 includes a first insert plate 51 vertically inserted into the upper end of the temporary holding tank 40. A crankshaft 53 is provided on one side of the first insert plate 51. A first drive motor 41 connected to the crankshaft 53 is provided outside the temporary holding tank 40. A second connecting rod 55 is sequentially connected to the rotating part of the crankshaft 53. A first connecting rod 54 rotatably connected to the end of the second connecting rod 55 is connected to the end of the second connecting rod 55. A guide plate 52 is connected to the bottom of the first connecting rod 54. The second connecting rod 55 connected to the crankshaft 53 is sequentially spaced on the side. The flow control assembly 50 is located on one side of the first mesh 42.

[0027] This invention utilizes a flow control component 50 at the inlet of the temporary holding tank 40. This allows the first drive motor 41 to power the crankshaft 53, which rotates. A second connecting rod 55, spaced apart on the side of the crankshaft 53, synchronously drives a first connecting rod 54, which in turn moves the guide plate 52. This allows for flexible adjustment of the flow rate and direction of the water at the inlet of the temporary holding tank 40, simulating the dynamic changes of natural ocean currents and adapting to the different developmental stages of silver pomfret fry. Furthermore, a first insert plate 51 is vertically inserted into the upper part of the temporary holding tank 40, providing stable support for the crankshaft 53, connecting rods, and other components, ensuring the operation of the transmission structure and preventing component misalignment during water flow adjustment. Additionally, the flow control component 50 is located on one side of the first mesh 42. Water adjusted by the guide plate 52 is buffered by the first mesh 42 before entering the temporary holding space, ensuring uniform water diffusion and preventing seedlings from being caught and damaged by the first mesh 42.

[0028] Below the second connecting rod 55 is a corresponding support rod 56. One end of the support rod 56 is fixedly connected to the first insert plate 51, and the other end of the support rod 56 can contact or separate from the first connecting rod 54. One end of the support rod 56 is fixedly connected to the first insert plate 51 to provide support for the upper transmission structure. When the first drive motor 41 drives the crankshaft 53, the second connecting rod 55, and the first connecting rod 54 to adjust the guide plate 52, the other end of the support rod 56 can contact the first connecting rod 54 to prevent the first connecting rod 54 from drooping excessively due to its own weight or water flow impact, and to prevent the transmission structure from shifting and causing the guide plate 52 to move out of position, thus ensuring the water flow adjustment effect and ensuring the stability of the ocean current simulation effect at the inlet of the temporary holding tank 40. At the same time, the support rod 56 and the first connecting rod 54 are only in contact or separate without being fixedly connected, and the first connecting rod 54 is not restricted from rotating and swinging normally with the transmission system.

[0029] A filter tank 20, connected to the second housing 30, is located on one side, and a first housing 10, connected to the filter tank 20, is located on the other side. The filter tank 20 contains a built-in water pump for drawing water from the first housing 10. This built-in pump actively draws water from the first housing 10, filtering it before it enters the second housing 30. This removes impurities, leftover food debris, and some harmful microorganisms, preventing contaminants from entering the second housing 30 with the water flow. The first housing 10, in conjunction with the first pump 71, provides continuous water supply. The filter tank 20 purifies the water, and the second housing 30 receives the purified water and converts it into a simulated ocean current using the pump 31.

[0030] The third tank 70 is equipped with a first pump 71 connected to it on its outer side. The first pump 71 is connected to the first tank 10 through a first pipe 72. The first pump 71 can pump water from the third tank 70 to the first tank 10 to form a water circulation. The first pump 71 draws water discharged from the temporary holding tank 40 received in the third tank 70 and transports it to the first tank 10 through the first pipe 72. This achieves a water circulation flow that passes through the first tank 10, filter tank 20, second tank 30, temporary holding tank 40, third tank 70, and first tank 10 in sequence, avoiding water waste. At the same time, the water can be purified again by the filter tank 20 during the circulation process, reducing the long-term accumulation of pollutants such as uneaten feed and feces in the temporary holding tank 40. In addition, according to the needs of seedling cultivation, a temperature control device can be built into the first tank 10 or the second tank 30 to regulate the water flow temperature, thereby controlling the simulated ocean current temperature and achieving a more realistic ocean current simulation effect.

[0031] See appendix Figure 6-8 As shown, the outflow end of the temporary holding tank 40 is equipped with an auxiliary component 60. The auxiliary component 60 includes a second insert plate 61 inserted into the wall of the outflow end of the temporary holding tank 40. The second insert plate 61 is horizontally set with the bottom of the temporary holding tank 40, and the second insert plates 61 are inserted at intervals on the wall of the temporary holding tank 40. The surface of each second insert plate 61 is provided with a first opening 62. The horizontally set and spaced-intercepting second insert plates 61 can buffer the water flow at the outflow end of the temporary holding tank 40, avoiding excessively fast water flow near the outflow end of the temporary holding tank 40, which would affect the fish fry in the direction of the outflow end of the temporary holding tank 40. Furthermore, the first openings 62 on the surface of the second insert plate 61 can ensure that the water carrying uneaten food and feces in the temporary holding tank 40 can flow smoothly to the third tank 70, and can also initially filter some of the larger particles of uneaten food and feces, reducing the amount of pollutants entering the subsequent circulation system.

[0032] On both sides of the bottom of the second insert plate 61, two connecting base plates 63 are respectively installed in a relative position. A sliding groove is formed on the connecting base plate 63, and a sliding bending plate 67 is provided inside the sliding groove. The sliding bending plate 67 is connected to the bottom surface of the second insert plate 61. In addition, a rotating plate 64 capable of rotation is installed at the end of each of the two connecting base plates 63. The two rotating plates 64 are connected by a swing plate 65. The sliding groove of the connecting base plate 63 allows the sliding bending plate 67 to slide along the groove, which is used to adjust the relative position of the sliding bending plate 67 and the bottom surface of the second insert plate 61, so as to realize the buffer range control of the water flow at the outlet end. The rotating plates 64 at the ends of the two connecting base plates 63 can rotate flexibly, driving the connected swing plates 65 to adjust the angle, which can guide the water flow direction at the outlet of the temporary holding tank 40, prevent local water flow stagnation or sudden changes in flow rate. In addition, the swing plates 65 help to move impurities that may settle in the upward direction in the temporary holding tank 40, thereby promoting their discharge from the temporary holding tank 40 and achieving a cleaning effect.

[0033] A sway plate 65 is connected to an interceptor cover 66, which has a mesh structure. The interceptor cover 66 can be circular, polygonal, or other shapes. The sway plate 65 and the mesh interceptor cover 66 remain connected at all times. The sway plate 65, connected to the interceptor cover 66, allows adjustment of the angle and coverage area of ​​the interceptor cover 66 to ensure it corresponds to the water flow path at the outlet of the holding tank 40, adapting to filtration needs at different flow rates. The mesh structure of the interceptor cover 66 not only helps intercept impurities but also helps reduce the water flow velocity at the outlet of the holding tank 40, ensuring smooth water discharge.

[0034] The temporary rearing box 40 adopts a long and narrow box structure with an open top. Between the inlet and outlet ends of the temporary rearing box 40, there is an interval space for biological aquaculture. The long and narrow box structure of the temporary rearing box 40 allows the water pump 31 in the second box 30 to form a continuous and stable flow channel between the inlet and outlet ends through the drain pipe 32. Combined with the ocean-like current regulated by the flow control component 50, this can cover the entire aquaculture interval space, meeting the swimming needs of the silver pomfret seedlings throughout the entire rearing area and avoiding dead zones in the water flow. The open design at the top of the temporary rearing box 40 facilitates staff observation of the seedling status and feeding. The aquaculture interval space between the inlet and outlet ends, along with the first mesh 42 at the inlet end, the second mesh 43 at the outlet end, and the auxiliary component 60, can prevent seedling contact parts from being lost with the water flow. Example 2:

[0035] This embodiment further discloses, based on Embodiment 1, and in conjunction with the appendix. Figure 1-8 The content shown discloses the water flow path of this device, and the specific flow path is as follows: Step 1: Water enters the filter tank 20 from the first tank 10 to complete the initial purification; The built-in water pump in the filter tank 20 actively draws water stored in the first tank 10. When the water flows through the filter tank 20, the filter structure inside the tank removes impurities, residual feed debris and some harmful microorganisms from the water, completing the initial purification of the water quality and preventing pollutants from entering the subsequent stages with the water flow and affecting the seedling environment.

[0036] Step 2: The purified water enters the second tank 30 to obtain ocean current power; After being purified by the filter tank 20, the water flows into the second tank 30 through the connecting pipe. The water pump 31 built into the second tank 30 provides stable power to the water, pressurizes the water and delivers it to the drain pipe 32. One end of the drain pipe 32 extends above the inlet of the temporary holding tank 40 to prepare for subsequent ocean current water supply.

[0037] Step 3: After the water is regulated by the flow control component 50, it enters the rearing space of the temporary holding box 40; The drain pipe 32 delivers pressurized water to the inlet of the temporary holding tank 40, where it first contacts the flow control component 50. The first drive motor 41 drives the crankshaft 53 to rotate, and the crankshaft 53 drives the first connecting rod 54 to move through the second connecting rod 55, which in turn pulls the guide plate 52 to flexibly adjust its angle, thereby realizing the dynamic adjustment of the water flow speed and direction, simulating the changes in natural ocean currents. The water flow regulated by the guide plate 52 passes through the first mesh 42 at the inlet of the temporary holding tank 40 and smoothly enters the breeding interval space of the temporary holding tank 40.

[0038] Step 4: The water flows within the temporary holding tank 40, carrying pollutants towards the outflow end and completing secondary filtration; The water flowing into the holding tank 40 flows along the inlet and outlet of the elongated tank, providing a dynamic current environment for the silver pomfret and carrying away pollutants such as uneaten feed and feces. When the water reaches the outlet of the holding tank 40, it first passes through the second mesh 43 to intercept the silver pomfret and prevent it from being lost with the water flow. Then the water flows through the auxiliary component 60, where the horizontally spaced second insert plates 61 buffer the water flow. At the same time, the mesh interceptor 66 connected to the swing plate 65 further intercepts small impurities and reduces the water flow speed. The water that has completed the secondary filtration flows into the third tank 70 through multiple through holes on the wall of the holding tank 40 and the corresponding connecting water pipe.

[0039] Step 5: The water flows back from the third tank 70 to the first tank 10, forming a closed loop.
