Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a graded aquaculture system. Background Technology

[0002] In the aquaculture industry, the growth of aquatic products (such as fish, shrimp, shellfish, etc.) typically goes through a process from larvae to adults, and their size and space requirements change significantly with each growth stage. Juvenile aquatic products are small in size and can be efficiently raised in smaller ponds; however, as they grow into adults, they require larger water spaces to ensure healthy growth and avoid diseases or stress caused by overcrowding.

[0003] Currently, common aquaculture models typically employ a phased transfer strategy, which involves using small rearing ponds during the juvenile stage and then transferring the offspring to larger rearing ponds by manual or mechanical harvesting once they reach a certain size.

[0004] However, when aquatic products are transferred by salvage, they are easily subjected to physical damage or stress during the transfer process, leading to stunted growth, decreased immunity, or even death. Utility Model Content

[0005] The purpose of this invention is to provide a graded aquaculture system that divides the aquaculture pond into multiple aquaculture areas by a partition net, and the multiple aquaculture areas can be connected by hoisting the partition net to facilitate the transfer of aquatic products, thus achieving the transfer of aquatic products directly without the need for harvesting.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a graded aquaculture system, including:

[0008] Aquaculture ponds;

[0009] A dividing net, along the length of the aquaculture pond, is capable of dividing the aquaculture pond into multiple aquaculture areas with progressively increasing volumes;

[0010] And a crane for lifting the partition net to create a passage for the supply of aquatic products between two adjacent aquaculture areas.

[0011] As one embodiment, the lifting height of the crane is not less than the vertical dimension of the partition net, and the crane is capable of moving along the length of the aquaculture pond.

[0012] As one embodiment, it also includes a covering shed, the aquaculture pond is arranged inside the covering shed, the main beam of the covering shed is arranged along the length of the aquaculture pond, and the crane is slidably mounted on the main beam.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this invention is to provide a graded aquaculture system to solve the problems existing in the prior art. Through a hoistable separating net, it enables the transfer of aquatic products without the need for retrieval.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1-7 The graded aquaculture system disclosed in this embodiment includes: an aquaculture pond 1, a partition net 2, and a crane 3. The aquaculture pond 1 is used for aquaculture. Along the length of the aquaculture pond 1, the partition net 2 divides the aquaculture pond 1 into multiple aquaculture areas with progressively increasing volumes. The crane 3 is used to lift the partition net 2 to form a channel for aquatic products to pass through between adjacent aquaculture areas. Its operating principle is as follows: the smallest aquaculture area is used for aquatic larvae, and the mesh size of the partition net 2 ensures that even the smallest aquatic product cannot pass through. When the first batch of larvae grows to a certain size, the partition net 2 is lifted by the crane 3. At this time, a channel for aquatic products is formed between the smaller and larger aquaculture areas. Aquatic products can swim directly from the smaller to the larger aquaculture area through this channel, completing the transfer without the need for retrieval. This avoids the problem of damage to aquatic products during the retrieval process and reduces labor intensity.

[0035] It is understandable that multiple breeding areas refer to at least two breeding areas. When a breeding pond 1 is equipped with one dividing net 2, the breeding pond 1 is divided into two breeding areas. When a breeding pond 1 is equipped with two dividing nets 2, the breeding pond 1 is divided into three breeding areas, and so on. When a breeding pond 1 is equipped with N dividing nets 2, the breeding pond 1 is divided into N+1 breeding areas.

[0036] In this embodiment, aquatic products include fish, shrimp, shellfish, etc.

[0037] In this embodiment, four partition nets 2 are arranged at intervals along the length of the aquaculture pond 1, dividing the aquaculture pond 1 into five aquaculture areas with progressively increasing volumes, thereby enabling the aquatic products to be raised in five stages.

[0038] In this embodiment, the lifting height of the crane 3 is not less than the vertical dimension of the partition net 2, and the crane 3 can move along the length of the aquaculture pond 1. The crane 3 can completely lift the partition net 2 from the aquaculture pond 1. The movable crane 3 can move the partition net 2 along the length of the aquaculture pond 1. Taking two partition nets 2 as an example, the two partition nets 2 from the first end to the second end of the aquaculture pond 1 are the first partition net 2 and the second partition net 2, respectively. The three aquaculture areas are, from smallest to largest, the first aquaculture area, the second aquaculture area, and the third aquaculture area. During the aquaculture process, the smallest volume aquatic products are placed in the first aquaculture area for rearing. After the aquatic products in the first aquaculture area grow to a certain size, the crane 3 lifts the first partition net 2 from the aquaculture pond 1 and moves it to the first end of the aquaculture pond 1. Then, the first partition net 2 is lowered back into the aquaculture pond 1. At this time, the crane 3 remains connected to the first partition net 2, and the crane 3 moves the first partition net 2 towards the second end of the aquaculture pond 1. During this process, the first partition net 2 has already... After being fully inserted into the aquaculture pond 1, the aquatic products cannot pass through the gap between the first separating net 2 and the aquaculture pond 1. Thus, the aquatic products can be driven to the second aquaculture area through the first separating net 2. At the same time, a certain amount of seedlings are continued to be introduced into the first aquaculture pond 1. The aquatic products in the first aquaculture area and the aquatic products in the second aquaculture area grow simultaneously. When the point where transfer is required is reached again, the second separating net 2 is first lifted and moved to the first end of the aquaculture pond 1. Then, the first separating net 2 is moved to the second end of the aquaculture pond 1 by the crane 3 (the first separating net 2 remains inside the aquaculture pond 1 throughout the process and is not lifted upwards). The aquatic products originally located in the second aquaculture area are transferred to the third aquaculture area. Finally, the second separating net 2 placed at the first end of the aquaculture pond 1 is moved to the second end by the crane 3 again. The aquatic products in the first aquaculture area are transferred to the second aquaculture area, and seedlings are continued to be introduced into the first aquaculture area. At this time, the aquatic products in the three aquaculture areas grow simultaneously. After the aquatic products in the third aquaculture area have grown, they can be harvested and sold, and the above transfer process is repeated. This method allows for faster transfer of aquatic products and enables adjustments to the number of aquaculture areas based on the farmers' sales needs, ensuring that there are always mature aquatic products available for sale at every sales point after the first batch. For example, the sales period could be one month.

[0039] In this embodiment, the graded aquaculture system also includes a covered shed 4, and the aquaculture pond 1 is set inside the covered shed 4. The covered shed 4 can isolate the aquatic products from the influence of the external environment.

[0040] Furthermore, the main beam 26 of the covering shed 4 is arranged along the length of the aquaculture pond 1, and the crane 3 is slidably mounted on the main beam 26. With this arrangement, there is no need to reserve operating space for the crane 3 on the ground, thus reducing the floor space occupied.

[0041] Of course, a conventional crane 3 with a traveling function can also be used to hoist the partition net 2.

[0042] In this embodiment, a slide rail 5 is provided on the main beam 26, and a first pulley 10 matching the slide rail 5 is provided on the hoist 3. Further, the slide rail 5 includes a connecting part and two supporting parts 13. The connecting part is connected to the main beam 26, and its cross-section is U-shaped. Two flanges 14 of the connecting part extend downwards, and the two supporting parts 13 are respectively installed on the opposite sidewalls of the two flanges 14. The two supporting parts 13 are spaced apart, allowing the first pulley 10 to enter between the U-shaped connecting parts. The first pulley 10 abuts against the side of the supporting part 13 near the web 15 of the connecting part. The pulley-slide rail 5 cooperation method has the advantages of good stability and smooth operation, improving the convenience and stability of the system in actual operation.

[0043] Preferably, a fixing plate 16 is provided on the web plate 15 of the connecting part, the fixing plate 16 is threadedly connected to the web plate 15, and the fixing plate 16 is bolted to the main beam 26 of the covering shed 4.

[0044] In this embodiment, the hoist 3 includes a motor 6 and a hoisting rope 7. A winding device 8 is provided on the output shaft of the motor 6. The first end of the hoisting rope 7 is connected to the winding device 8, and the second end of the hoisting rope 7 is provided with a hook for hoisting the partition net 2. In use, the hook is used to connect with the partition net 2. The motor 6 rotates to drive the winding device 8 to rotate, winding or releasing the hoisting rope 7, thereby enabling the partition net 2 to be hoisted or lowered.

[0045] Understandably, motor 6 is connected to the power source via wires.

[0046] In this embodiment, the crossbeam of the partition net 2 is provided with a vertical hanging rod 17 and two side rods 18 arranged in a V-shape. A lifting ring 28 is provided at the intersection of the three, which is used to cooperate with the hook on the hoist 3.

[0047] In this embodiment, the hoist 3 includes a sliding beam 19, a first pulley 10 is installed on the upper part of the sliding beam 19, the upper part of the sliding beam 19 extends through the gap between the two support parts 13 into the connecting part, and a motor 6 is installed on the lower part of the sliding beam 19. The first pulley drives the motor 6 to move through the sliding beam 19.

[0048] In this embodiment, a pull rope 20 is provided on the motor 6. The pull rope 20 extends downward, and the operator can pull the pull rope 20 to make the hoist slide on the slide rail 5.

[0049] In this embodiment, a drive motor is provided on the sliding beam 19. The output shaft of the drive motor is connected to the first pulley 10 for transmission. The drive motor can drive the first pulley 10 to rotate, so as to realize the movement of the hoist.

[0050] In this embodiment, a sewage discharge channel 9 is also included. The sewage discharge channel 9 is connected to the aquaculture pond 1, and the sludge or pond water in the aquaculture pond 1 can be discharged through the sewage discharge channel 9.

[0051] In this embodiment, a sewage pipe 21 is provided at one end of the sewage discharge channel 9, and a sewage pipe 21 is provided at the downstream end of the sewage pipe 21. A valve is provided on the sewage pipe 21 to control the flow of water. Furthermore, the graded aquaculture system has a sewage ditch 22, through which sewage can be guided to the target area.

[0052] In this embodiment, along the length of the vertical aquaculture pond 1, the bottom cross-section of the aquaculture pond 1 is a cone shape with the size gradually decreasing from top to bottom. The sewage discharge channel 9 is set below the aquaculture pond 1 and is arranged along the length of the aquaculture pond 1. The sewage discharge channel 9 is connected to the lowest point of the aquaculture pond 1. With this arrangement, the sludge or pond water in the aquaculture pond 1 can be completely discharged. Moreover, when it is not necessary to drain water but only to remove sludge and other impurities, the impurities will accumulate at the bottom of the aquaculture pond 1 under the action of gravity, and the impurities can be discharged without replacing all the pond water.

[0053] In this embodiment, the cross-section of the aquaculture pond 1 is pentagonal along the length of the vertical aquaculture pond 1, and the corresponding partition net 2 is also pentagonal in structure.

[0054] Preferably, the dividing mesh 2 includes a pentagonal frame and a dense mesh 27 mounted on the frame.

[0055] In this embodiment, a second pulley 11 is provided on the top of the partition net 2. The top of the partition net 2 extends upward out of the breeding pond 1. The second pulley 11 is installed on the partition net 2 through a wheel axle. The wheel axle extends outward from the breeding pond 1 in a horizontal direction, so that the second pulley 11 can roll and cooperate with the top surface of the side wall of the breeding pond 1. The provision of the second pulley 11 reduces the resistance of the partition net 2 during the process of moving along the length of the breeding pond 1 within the breeding pond 1.

[0056] In this embodiment, the outer edge of the partition net 2 is provided with a brush 12 that abuts against the inner wall of the aquaculture pond 1. The brush 12 can be used to scrub the inner wall of the aquaculture pond 1 to remove impurities adhering to the aquaculture pond 1.

[0057] In this embodiment, the aquaculture pond 1 includes two inclined bottom surfaces 23, two vertically arranged long sides 24, and two vertically arranged short sides 25. The two long sides 24 extend along the length direction of the aquaculture pond 1, and the two short sides 25 extend along the width direction of the aquaculture pond 1. The bottom surfaces 23 and the long sides 24, the bottom surfaces 23 and the short sides 25, and the long sides 24 and the short sides 25 are all sealed together.

[0058] Practical simulation: The existing breeding pond is 120 meters long and has a water volume of 120 cubic meters. According to Table 1, the water volume requirements for tilapia breeding in stages are as follows.

[0059] Table 1

[0060]

[0061]

[0062] In reality: The existing aquaculture pond is 120 meters long with a water volume of 1200 cubic meters and a longitudinal cross-sectional area of ​​10 square meters. The length ratio represents the volume ratio. The pond segment lengths and water volumes corresponding to different stages of cultivation are shown in Table 2. The pond lengths (in meters) obtained for different cultivation stages in a 120-meter pond are shown in Table 2.

[0063] Table 2

[0064]

[0065] The sum of all lengths is 122 meters, so the relaxed length is filled by the 5th stage with the maximum length: so the length of the 5th stage is set at 64 meters.

[0066] Using the five stages of cultivation as the limiting factor for large-scale aquaculture, that is, 45,440 tilapia (71 tilapia / cubic meter × 640 cubic meters), as the stocking quantity for each stage. The ponds were divided into sections of 1 meter, 3 meters, 14 meters, 38 meters, and 64 meters. After the ponds were divided, stage 1 cultivation was initially carried out, followed by stage 2 cultivation after one month, with additional stage 1 cultivation stock added, and so on. After 5 months, a batch of marketable tilapia was harvested monthly. After the marketable fish were harvested, the pond divider between stages 4 and 5 was moved to the beginning of the cultivation area, and 50,000 fry were added (considering survival rates). This ensured that each production line produced 32.0 tons of marketable tilapia with an average size of 700 grams / fish per month. After normal operation, the production efficiency and effectiveness were far higher than previous general facility aquaculture.

[0067] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
