Description

Technical Field

[0001] This invention relates to the field of diverted aquaculture technology, specifically a diverted aquaculture ecological farm and a method for diverting fish fry for aquaculture. Background Technology

[0002] In the aquaculture industry, diverted water ecological aquaculture is a common and efficient farming model. It involves setting up a frame consisting of pillars and support rods in a flowing water area, and fixing interception nets on it to form relatively independent farming units. This model can utilize flowing water to ensure dissolved oxygen and water quality, while also effectively managing fish populations.

[0003] A typical diversion water ecological aquaculture farm includes a support structure and a barrier net. The support structure is fixedly connected to the bottom foundation, and the barrier net is usually directly tied to the support structure with ropes or fasteners. The barrier net is laid vertically along the height of the support structure until it extends to the bottom of the water. The layout of the support structure and the barrier net can form an aquaculture space. The holes in the barrier net are used for the exchange of water nutrients and can restrict the activity space of fish fry.

[0004] Floating debris (such as leaves, algae, and foam) easily accumulates on the upstream edge of the interception net. This accumulation not only clogs the mesh and hinders water exchange, but its decay also accelerates the aging of the net material and may breed harmful bacteria, affecting fish health. Currently, cleaning this floating debris mainly relies on regular manual dredging, which is inefficient, labor-intensive, and poses safety risks at high water levels or with fast currents. Furthermore, uneaten feed and feces produced during aquaculture accumulate on the bottom, forming sediment. Traditional fixed support frames are close to the bottom, easily obstructing natural water exchange and the spread of sediment. Long-term accumulation may lead to bottom sediment deterioration, affecting bottom water quality and negatively impacting the growth of benthic fish. Summary of the Invention

[0005] The purpose of this invention is to provide an ecological aquaculture farm with diverted waterways and a method for diverting fish fry for aquaculture, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A diversion water ecological aquaculture farm includes multiple sets of columns arranged along the direction of water flow and along the width of the water area, the columns being fixedly connected to the underwater foundation; Multiple sets of support rods are provided between adjacent columns along the width of the water area, and the support rods are used to fix the interception net. Sliding blocks are fixedly installed at both ends of the support rod, and the sliding blocks are provided with connecting structures for connecting adjacent support rods. It also includes a snap-fit ​​structure for connecting the sliding block and the column; The snap-fit ​​structure includes abutting blocks that are slidably installed and symmetrically arranged on the sliding block. When the connecting structure connects two adjacent sliding blocks, the abutting blocks on the lower sliding block can approach each other and snap into the column. The column is provided with a sinking structure, which includes a sliding block that is slidably connected to the column. The sliding block can slide downward along the height direction of the column and abut against the uppermost sliding block during the downward movement, so as to drive the sliding block and the corresponding support rod to move downward synchronously and shorten the distance between adjacent support rods.

[0007] As described above, the diversion water ecological aquaculture farm includes an upper connecting sleeve and a lower connecting sleeve fixedly installed on the sliding block; a connecting post that is slidably fitted onto the lower connecting sleeve and sleeved with the upper connecting sleeve; a contraction spring is provided inside the lower connecting sleeve; the two ends of the contraction spring abut against the lower connecting sleeve and the connecting post, respectively.

[0008] As described above, the diversion water ecological aquaculture farm includes a locking groove formed on the upper connecting sleeve, a locking wedge block that slidably engages with the locking groove on the connecting column, and a locking spring provided inside the connecting column, with both ends of the locking spring abutting against the locking wedge block and the connecting column, respectively.

[0009] As described above, the diversion water ecological aquaculture farm includes a fixing plate fixedly installed on the column. The fixing plate has a wide slot and a narrow slot that are interconnected and opened downwards along its height. A roller is rotatably installed on the abutting block. The roller can roll and cooperate with the wide slot and the narrow slot. A retaining spring is provided in the sliding block. The two ends of the retaining spring abut against the retaining block and the sliding block, respectively.

[0010] As described above, the diversion water ecological aquaculture farm includes the following: the snap-fit ​​structure further includes a limiting post slidably installed within the sliding block, the limiting post having a clearance groove; a limiting wedge block fixedly installed on the abutting block, which can abut against the limiting post and cooperate with the clearance groove; a return spring is provided inside the sliding block, the two ends of the return spring abutting against the sliding block and the limiting post respectively; a mating post slidably installed inside the upper connecting sleeve, which abuts against the limiting post, and the mating post abuts against the connecting post.

[0011] As described above, the diversion water ecological aquaculture farm includes: a submerged structure comprising a motor fixedly mounted on the column, a lead screw fixedly mounted on the output end of the motor, a drive frame and a sliding frame slidably mounted on the column, a threaded sleeve fixedly mounted on the drive frame and threadedly engaged with the lead screw; a sliding block slidably engaging with the sliding frame; a slot and groove communicating with each other on the fixed plate and slidably engaging with the sliding block; multiple sets of drive columns fixedly mounted on the drive frame; one drive column abutting against the sliding frame, and a large spring provided on the sliding frame, with both ends of the large spring abutting against the sliding frame and the drive column respectively.

[0012] As described above, the diversion water ecological aquaculture farm includes: a sinking structure further comprising a rotating sleeve rotatably mounted on the sliding frame; a fixed sleeve fixedly mounted on the column to engage with the rotating sleeve; a protruding column fixedly mounted on the fixed sleeve; a groove group formed on the rotating sleeve to slide with the protruding column; a driving wedge fixedly mounted on the rotating sleeve; a mating wedge fixedly mounted on the sliding block to engage with the driving wedge; a small spring provided on the sliding frame; and two ends of the small spring abutting against the sliding frame and the mating wedge, respectively.

[0013] As described above, in the diversion water ecological aquaculture farm: the trough assembly includes a guide straight trough and an inclined trough that are interconnected, wherein one end of the guide straight trough passes through the rotating sleeve, and the guide straight trough is used to guide the protruding column into the inclined trough; when the inclined trough and the protruding column are engaged, the driving wedge and the engaging wedge are engaged.

[0014] As described above, in the diversion water ecological aquaculture farm: an upper frame is slidably installed on the column, and an upper slider that slides in cooperation with the chute is fixedly installed on the upper frame; and the upper frame abuts against one of the drive columns.

[0015] A method for diverting and raising fish fry using a diverted water ecological aquaculture farm as described above includes the following steps. Step 1: In the aquaculture area, set up multiple sets of columns according to the predetermined layout to form an aquaculture grid, and fix the interception net to the support rods. Connect all sliding blocks to the corresponding columns through the snap-fit ​​structure, so that the support rods are distributed in sequence along the height direction to form an aquaculture space; Step 2: Introduce fish fry and feed them, observing and recording the condition of floating objects in the waters within the breeding area; Step 3: When there are too many floating objects on the water surface, the uppermost support rod and interception net are temporarily lowered below the water surface by controlling the sinking structure; at this time, the floating objects can be naturally carried away by the water flow or can be easily cleaned up manually without the obstruction of the interception net. Step 4: After removing the floating debris, reset the control support rod and continue to monitor the floating debris and the growth of the fish fry.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: The connecting structure allows for a tighter connection between the support rods and facilitates control over the spacing between them, thereby controlling the tension of the interception net and preventing it from breaking under the impact of water flow due to excessive tension, thus preventing the loss of fish fry. It also avoids the problem of excessively close spacing between support rods hindering water exchange and affecting dissolved oxygen and nutrient diffusion, creating a better growth environment for the fish fry. Furthermore, the cooperation between the connecting structure and the snap-fit ​​structure increases the resistance to the downward movement of the support rods, preventing the interception net from breaking due to excessively rapid sinking. The snap-fit ​​structure only activates after the connecting structure is completed, fundamentally eliminating the risk of the support rods and interception net accidentally sinking to the bottom due to installation oversights (such as unconnected or loosely connected support rods), improving the structural stability of the entire aquaculture facility and the controllability of the installation process. The driving mechanism of the sinking structure allows control over the tension of the uppermost layer of the net. The support rods and interception net are temporarily and stably submerged below the water surface. When floating debris (such as fallen leaves, foam, algae, etc.) accumulates at the interception net at the water-facing end, the debris can be quickly cleared, allowing it to drift away naturally with the water flow or be easily collected. This not only greatly improves cleaning efficiency and reduces the labor intensity of manual cleaning, but more importantly, it prevents floating debris from adhering to and corroding the interception net for a long time, thereby extending the service life of the interception net and reducing the long-term operation and maintenance costs of the aquaculture farm. The submerged structure not only allows the support rods to descend, but also drives the bottom support rods and interception net to rise by driving the upward frame. When too much mud and sludge accumulates at the bottom of the water due to feed residue, fish feces, etc., this measure can temporarily increase the bottom space, reduce the flow resistance of the mud and sludge, and promote its diffusion with the water flow or its sedimentation and centralized treatment. This helps to improve the water quality and dissolved oxygen conditions at the bottom of the aquaculture area, creating better living conditions for benthic or full-water-layer fish.

[0029] 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.

[0030] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0031] Please see Figures 1-11 As an embodiment of the present invention, the diversion water ecological aquaculture farm includes multiple sets of columns 1 arranged along the water flow direction and along the width of the water area, and the columns 1 are fixedly connected to the bottom foundation. Multiple sets of support rods 25 are provided between adjacent columns 1 along the width of the water area, and the support rods 25 are used to fix the interception net. Both ends of the support rod 25 are fixedly installed with sliding blocks 4, and the sliding blocks 4 are provided with a connecting structure for connecting adjacent support rods 25. It also includes a snap-fit ​​structure for connecting the sliding block 4 and the column 1; The snap-fit ​​structure includes abutting blocks 5 that are slidably installed and symmetrically arranged on the sliding block 4. When the connecting structure connects two adjacent sliding blocks 4, the abutting blocks 5 on the lower sliding block 4 can approach each other and snap-fit ​​with the column 1. The column 1 is provided with a sinking structure, which includes a sliding block 23 that is slidably connected to the column 1. The sliding block 23 can slide downward along the height direction of the column 1 and abut against the uppermost sliding block 4 during the downward movement, so as to drive the sliding block 4 and the corresponding support rod 25 to move downward synchronously and shorten the distance between adjacent support rods 25.

[0032] In this embodiment, in the aquaculture water area, multiple sets of columns 1 are set up according to a predetermined layout to form an aquaculture grid, and the interception net is fixed on the support rod 25. All sliding blocks (4) are connected to the corresponding columns 1 through a snap-fit ​​structure, so that each support rod 25 is distributed in sequence along the height direction to form an aquaculture space.

[0033] During the installation of the support rod 25, after one support rod 25 is initially connected to the column 1, the two support rods 25 are connected through the connecting structure. After the connection, the lower support rod 25 can move downward along the height direction of the column 1. That is, before the support rods 25 are connected to each other (when the support rods 25 are initially connected to the column 1), the abutting block 5 can only slide a short distance on the column 1. At this time, the abutting blocks 5 cannot get close to each other (the snap-fit ​​structure limits the abutting block 5). When the two support rods 25 are connected through the connecting structure, the abutting block 5 is released from the restriction and can get close to each other, so that the sliding block 4 can continue to slide smoothly downward on the column 1. The connecting structure allows for a tighter connection between the support rods 25, facilitating control over the spacing between them and thus controlling the tension of the interception net. This prevents the net from becoming excessively taut and breaking underwater, which could lead to the loss of fish fry. It also avoids overly dense gaps that could obstruct the normal exchange of nutrients and oxygen in the water. Furthermore, the interaction between the connecting structure and the snap-fit ​​structure increases the sliding resistance of the support rods 25, preventing excessively rapid sinking that could cause the net to break. The snap-fit ​​structure only activates after the connecting structure is completed, thus preventing the support rods 25 from sinking to the bottom due to incomplete or improper connection.

[0034] After the fish fry are introduced, they are fed; during the rearing process, the floating status on the water surface is observed.

[0035] When too much floating debris accumulates at the top support rod 25 on the water-facing side, the sinking structure is controlled to move, thereby driving the lower slider 23 to move downwards along the height direction of the column 1. During the movement, the lower slider 23 will contact and drive the top support rod 25 to move synchronously, so as to compress the gap between the overall support rods 25, so that the top support rod 25 sinks into the water body, making it easier for the water flow to wash away the floating debris. This can prevent floating debris from being attached to the interception net for a long time and accelerating the damage to the interception net, and can improve the cleaning efficiency of the interception net with less impact on the growth of fish fry.

[0036] As a further embodiment of the present invention, the connection structure includes an upper connecting sleeve 7 and a lower connecting sleeve 11 fixedly installed on the sliding block 4; a connecting post 8 that is slidably fitted on the lower connecting sleeve 11 and sleeved with the upper connecting sleeve 7; a contraction spring 12 is provided inside the lower connecting sleeve 11; the two ends of the contraction spring 12 abut against the lower connecting sleeve 11 and the connecting post 8 respectively.

[0037] As a further embodiment of the present invention, the connecting structure further includes a locking groove 701 formed on the upper connecting sleeve 7, and a locking wedge 10 that cooperates with the locking groove 701 is slidably installed on the connecting post 8; and a locking spring 9 is provided inside the connecting post 8, with both ends of the locking spring 9 abutting against the locking wedge 10 and the connecting post 8 respectively.

[0038] In this embodiment, after one support rod 25 is initially connected to the column 1, the next support rod 25 is installed. During the installation process, the position of the support rod 25 is adjusted so that the lower connecting sleeve 11 on the upper sliding block 4 is aligned with the upper connecting sleeve 7 on the sliding block 4 on the initially installed support rod 25 (the connecting column 8 and the upper connecting sleeve 7 are concentric). Then, an external force is applied to insert the connecting column 8 into the upper connecting sleeve 7 (the tension spring 12 has a large elastic force), and during this process, the upper connecting sleeve 7 and the lower connecting sleeve 11 are engaged.

[0039] During the insertion of the connecting post 8 into the upper connecting sleeve 7, the locking wedge 10 will first come into contact with the upper connecting sleeve 7. Through the squeezing action, the locking wedge 10 can be made to retract inward and compress the locking spring 9, thereby reducing the resistance of the insertion of the connecting post 8.

[0040] Then, the connecting post 8 extends into the upper connecting sleeve 7, thereby driving the locking wedge 10 closer to the locking groove 701; and when the locking groove 701 and the locking wedge 10 are aligned with each other, under the elastic force of the locking spring 9, the locking wedge 10 can enter the locking groove 701; then, through the contact and cooperation between the groove wall of the locking groove 701 and the locking wedge 10, the upper connecting sleeve 7 and the connecting post 8 can be firmly connected together, thereby making the upper connecting sleeve 7 and the lower connecting sleeve 11 securely connected.

[0041] When the sinking structure moves and the uppermost support rod 25 moves downward, the distance between the multiple support rods 25 will shorten (the upper connecting sleeve 7 will slide inside the lower connecting sleeve 11, compressing the spring 12), so that the uppermost support rod 25 can smoothly enter the water surface and facilitate the movement of floating objects.

[0042] By connecting the support rods 25 through the connecting structure, the connection between the support rods 25 can be made tighter, and the spacing between the support rods 25 can be easily controlled, thereby controlling the tension of the interception net to avoid the interception net from being too tight and breaking underwater, causing the loss of fish fry. It can also avoid the excessively dense support gaps from hindering the normal exchange of nutrients and oxygen in the water.

[0043] As a further embodiment of the present invention, the snap-fit ​​structure further includes a fixing plate 3 fixedly installed on the column 1. The fixing plate 3 has a wide slot 301 and a narrow slot 302 that are interconnected and opened downward along its height direction. A roller 502 is rotatably installed on the abutting block 5. The roller 502 can roll and cooperate with the wide slot 301 and the narrow slot 302. A pressing spring 6 is provided in the sliding block 4. The two ends of the pressing spring 6 abut against the abutting block 5 and the sliding block 4, respectively.

[0044] As a further embodiment of the present invention, the snap-fit ​​structure further includes a limiting post 14 slidably installed in the sliding block 4, the limiting post 14 having a clearance groove 1401; a limiting wedge 501 fixedly installed on the abutting block 5, which can abut against the limiting post 14 and cooperate with the clearance groove 1401; a return spring 15 is provided in the sliding block 4, the two ends of the return spring 15 abut against the sliding block 4 and the limiting post 14 respectively; a mating post 13 slidably installed in the upper connecting sleeve 7, which abuts against the limiting post 14, and the mating post 13 abuts against the connecting post 8.

[0045] In this embodiment, in the initial state, the distance between the abutting blocks 5 is relatively large (slightly smaller than the width of the wide slot 301 and larger than the width of the narrow slot 302), and the limiting wedge block 501 is misaligned with the relief slot 1401 and abuts against the limiting post 14 (the abutting blocks 5 cannot get close to each other).

[0046] Initial connection: Connect the sliding block 4 to the wide slot 301 and slide the sliding block 4 to the point where the wide slot 301 and the narrow slot 302 are connected. At this time, since the distance between the pressing blocks 5 is greater than the width of the narrow slot 302, the sliding block 4 cannot enter the narrow slot 302.

[0047] During the process of connecting another support rod 25 through the connecting structure, the connecting column 8 will press the mating column 13 to move it closer to the limiting column 14. The surface of the limiting column 14 that abuts against the mating column 13 is inclined. Therefore, during the movement of the mating column 13, it will press the limiting column 14 through the inclined surface to make it slide towards the column 1, thereby making the clearance groove 1401 close to the limiting wedge block 501 and compress the return spring 15. When the connecting structure securely connects the two support rods 25, the clearance groove 1401 and the limiting wedge block 501 are aligned. At this time, the abutting block 5 is in the contact limiting state (able to move closer to each other).

[0048] Then, an external force is applied to make the sliding block 4 slide towards the narrow groove 302. During this process, the groove wall of the narrow groove 302 will squeeze the pressing block 5 to make them closer to each other (the gap is reduced) and compress the pressing spring 6 so that the sliding block 4 can smoothly enter the narrow groove 302. During the sliding of the sliding block 4 in the narrow groove 302, the elastic force of the pressing spring 6 can make the roller 502 abut against the groove wall. Through the rolling cooperation between the roller 502 and the fixing plate 3, the installation can be prevented from getting stuck.

[0049] The cooperation between the connecting structure and the snap-fit ​​structure increases the sliding resistance of the support rod 25, preventing the interception net from breaking due to excessive sinking speed. The snap-fit ​​structure only operates after the connecting structure is connected, thus preventing the support rod 25 from sinking to the bottom of the water if it is not connected or not properly connected.

[0050] As a further embodiment of the present invention, the sinking structure includes a motor 2 fixedly mounted on the column 1, a lead screw 16 fixedly mounted on the output end of the motor 2, a drive frame 17 and a sliding frame 19 slidably mounted on the column 1, a threaded sleeve 1701 that is threadedly engaged with the lead screw 16 fixedly mounted on the drive frame 17, a sliding block 23 that is slidably engaged with the sliding frame 19, a slot 303 and a groove 304 that are slidably engaged with and interconnected with the sliding block 23 on the fixing plate 3, a plurality of drive columns 18 fixedly mounted on the drive frame 17, one drive column 18 abutting against the sliding frame 19, and a large spring 26 is provided on the sliding frame 19, with both ends of the large spring 26 abutting against the sliding frame 19 and the drive column 18 respectively.

[0051] In this embodiment, in the initial state, the lower slider 23 is completely submerged in the groove 303. At this time, the lower slider 23 does not cooperate with the slide groove 304, which can prevent the lower slider 23 from hindering the sliding block 4 from sliding in the wide groove 301, thereby reducing the installation resistance.

[0052] When the motor 2 is activated, it will drive the lead screw 16 to rotate, thereby driving the threaded sleeve 1701 to move along the length of the lead screw 16 through the threaded engagement, thus driving the drive frame 17 to move synchronously.

[0053] When the drive frame 17 moves downward, it drives the drive column 18 to move synchronously, and through the action of resistance, it drives the sliding frame 19 to move downward. During the movement, the lower slider 23 slides outward in the slot 303 to gradually extend out of the slot 303, and the lower slider 23 enters the slide groove 304. Then, the sliding lower slider 23 will contact the sliding block 4 on the uppermost support rod 25, and drive the sliding block 4 to move downward synchronously, thereby driving the upper connecting sleeve 7 to slide inward in the lower connecting sleeve 11 and compressing the spring 12. During this process, the distance between the multiple sets of support rods 25 shortens, and the uppermost support rod 25 will gradually sink into the water surface; this facilitates the flow of water to carry away the floating objects.

[0054] After the floating debris is cleared, the control screw column 16 rotates in the opposite direction, thereby causing the sliding frame 19 to move upward to reset through the elastic force of the large spring 26. Under the elastic force of the contraction spring 12, the spacing between the multiple sets of support rods 25 will be restored, thus restoring the breeding space.

[0055] As a further embodiment of the present invention, the sinking structure further includes a rotating sleeve 22 rotatably mounted on the sliding frame 19, a fixed sleeve 21 fixedly mounted on the column 1 and sleeved with the rotating sleeve 22, and a protruding column 2101 fixedly mounted on the fixed sleeve 21; the rotating sleeve 22 is provided with a groove group that slides with the protruding column 2101; a driving wedge 2203 is fixedly mounted on the rotating sleeve 22, and a mating wedge 2301 that mates with the driving wedge 2203 is fixedly mounted on the sliding block 23; a small spring 24 is provided on the sliding frame 19; the two ends of the small spring 24 abut against the sliding frame 19 and the mating wedge 2301, respectively.

[0056] As a further embodiment of the present invention, the groove group includes a guide straight groove 2201 and an inclined groove 2202 that are interconnected, wherein one end of the guide straight groove 2201 passes through the rotating sleeve 22, and the guide straight groove 2201 is used to guide the protruding post 2101 into the inclined groove 2202; when the inclined groove 2202 and the protruding post 2101 are engaged, the driving wedge 2203 is engaged with the engaging wedge 2301.

[0057] In this embodiment, during the downward movement of the sliding frame 19, the rotating sleeve 22 will slide outward in the fixed sleeve 21, thereby causing the protruding column 2101 to slide in the groove.

[0058] Initially, the protruding post 2101 is located in the inclined groove 2202. Therefore, during the outward sliding of the rotating sleeve 22, the protruding post 2101 will first slide in the inclined groove 2202, thereby causing the rotating sleeve 22 to rotate, which in turn drives the drive wedge 2203 to rotate. During the rotation, the drive wedge 2203 presses against the mating wedge 2301, causing it to slide horizontally away from the rotating sleeve 22 and compress the small spring 24. During this process, the lower slider 23 slides outward in the slot 303 so that it extends out of the slot 303 (its projection on the horizontal plane coincides with the sliding block 4).

[0059] When the protruding post 2101 slides in the guide groove 2201, the rotating sleeve 22 does not rotate. At this time, the lower slider 23 remains extended and slides with the groove 304. Under the elastic force of the small spring 24, the lower slider 23 abuts against the fixed plate 3.

[0060] The sliding frame 19 continues to slide, which can drive the lower slider 23 to slide synchronously (slide in the slide groove 304), thereby contacting the uppermost slider 4 and driving it to slide downward to compress the gap between the support rods 25.

[0061] As a further embodiment of the present invention, an upper frame 20 is slidably mounted on the column 1, and an upper slider 2001 that slides in cooperation with the slide groove 304 is fixedly mounted on the upper frame 20; and the upper frame 20 abuts against one of the drive columns 18.

[0062] In this embodiment, when too much mud and sludge accumulates at the bottom of the water, the control screw 16 rotates to drive the drive frame 17 to slide upwards. The drive column 18 drives the upper frame 20 to move synchronously (during the downward movement of the drive frame 17, the drive column 18 will separate from the upper frame 20). This causes the upper slider 2001 to drive the sliding block 4 on the bottom support rod 25 to slide upwards, thereby lifting the support rod 25 and reducing the flow resistance of the mud and sludge at the bottom of the water, achieving the effect of cleaning the bottom of the water. During this process, the drive column 18 will separate from the lower frame 19 and compress the large spring 26.

[0063] A method for diverting and raising fish fry using a diverted water ecological aquaculture farm as described above includes the following steps. Step 1: In the aquaculture area, set up multiple sets of columns 1 according to the predetermined layout to form an aquaculture grid, and fix the interception net on the support rods 25. Connect all the sliding blocks 4 to the corresponding columns 1 through the snap-fit ​​structure, so that each support rod 25 is distributed in sequence along the height direction to form an aquaculture space. Step 2: Introduce fish fry and feed them, observing and recording the condition of floating objects in the waters within the breeding area; Step 3: When there are too many floating objects on the water surface, the uppermost support rod 25 and the interception net are temporarily lowered below the water surface by controlling the sinking structure; at this time, the floating objects on the water surface can be naturally washed away by the water flow or can be easily cleaned up manually without the obstruction of the interception net. Step 4: After the floating debris is removed, control the support rod 25 to reset and continue to monitor the floating debris and the growth of the fish fry.
