Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a grading box for industrialized bass farming. Background Technology

[0002] In the aquaculture industry, fish fry rearing is a crucial initial stage in the entire aquaculture process. Fish fry usually refer to the juvenile stage from hatching to adulthood. At this stage, the fish fry are small in size, their physiological functions are not yet fully developed, and their survival ability is relatively fragile. They have extremely high requirements for the breeding environment, feeding methods, and management measures. Farmers need to provide special and meticulous care to ensure their normal growth and development, laying a good foundation for subsequent adult fish farming.

[0003] Fish fry can be obtained through various means, mainly including natural hatching, artificial hatching, and purchasing from professional farms or suppliers. Natural hatching involves fish laying eggs in natural waters and relying on natural environmental conditions to complete the hatching process, thus obtaining fish fry. Artificial hatching involves farmers controlling key factors in the hatching environment, such as water temperature, light intensity, and water pH, to create suitable hatching conditions for the fish eggs, thereby increasing the hatching rate and ensuring a stable supply of fish fry. Purchasing fish fry involves farmers directly buying fish fry that meet their specifications from qualified specialized farms or suppliers according to their own breeding needs. This method saves time and costs in the hatching process and is currently a common way for many farms to obtain fish fry.

[0004] During fish fry farming, due to differences in hatching time and growth rate, even fry from the same batch can vary in size. If fry of different sizes are mixed in the same farming device, not only will the living space of smaller fry be severely squeezed, but competition among the fry will also occur. Especially when feeding, larger fry will have the advantage and seize more food resources, while smaller fry will not be able to get enough food, their growth and development will be inhibited, and they may even die from starvation. This will seriously affect the overall survival rate and growth quality of the fry. Therefore, in order to achieve refined fish fry farming and ensure that fry of different sizes can get a good growth environment and sufficient food, a special grading device is needed to grade the fry during the fish fry farming process.

[0005] In the prior art, Chinese utility model patent with publication number CN207604383U discloses a mobile fish fry rearing box. The rearing box mainly consists of a fish fry rearing box, a base, and a water tank. The bottom of the base is equipped with a drive device on the left and right sides. With the help of the drive device, the fish fry rearing box can be moved to an environment suitable for fish fry growth when the weather is too cold or too hot, which is beneficial to improving the survival rate of fish fry to a certain extent and has a certain practicality. However, in the actual application, this mobile fish fry rearing box still has obvious defects and shortcomings. Its overall structure is relatively simple, and there is no special fish fry grading device inside. When used for fish fry rearing, it is impossible to separate fish fry of different sizes for rearing, and can only carry out mixed rearing operations.

[0006] This deficiency is particularly pronounced in sea bass fry farming. Sea bass, a farmed fish with high economic value, exhibits significant differences in growth rate among its fry. If the aforementioned mobile fry rearing tanks are used, the lack of a grading function directly impacts the fry rearing results. Firstly, when sea bass fry are mixed-species, larger fry will aggressively compete for food from smaller fry, causing the smaller fry to grow slowly due to insufficient feeding and failing to reach their expected size. Secondly, the device cannot quickly distinguish between larger fry, hindering farmers from implementing differentiated management measures for fry of different sizes, such as adjusting feeding amounts and controlling stocking density, thus affecting the overall quality of fry rearing and subsequent farming efficiency. Utility Model Content

[0007] To address the aforementioned problems, this invention proposes a grading box for industrialized sea bass farming, which more accurately solves the problems described above.

[0008] This utility model is achieved through the following technical solution:

[0009] This utility model proposes a grading box for industrialized sea bass farming, comprising an annular box body. Inside the annular box body, coarse grading filter plates, medium grading filter plates, small grading filter plates, and micro grading filter plates are arranged and fixedly installed in a ring at equal intervals. A sealing mechanism is fixedly installed in the middle of the annular box body, with its sealing ends covering one side of each of the coarse, medium, small, and micro grading filter plates. A vortex drive mechanism is fixedly installed at equal intervals on the outer side of the annular box body, with both its input and output ends connected to the inside of the annular box body. The annular box body is divided into four fish-raising chambers by the coarse, medium, small, and micro grading filter plates. A drainage module is fixedly installed at the bottom of the annular box body, with its top connected to the bottom of the fish-raising chambers.

[0010] Furthermore, the vortex drive mechanism includes arc-shaped tubes, which are arranged in a ring at equal intervals and fixedly installed on the outside of the ring-shaped box. The input and output ends of each arc-shaped tube are connected to the inside of the fish tank at the corresponding position. A water pump is fixedly installed in the middle of the outer side of the arc-shaped tube, and the input and output ends of the water pump are connected to the inside of the fish tank through the arc-shaped tubes.

[0011] Furthermore, fish-proof filters are fixedly installed at both ends of the arc-shaped tube, and the fish-proof filters are arranged to cover the input and output ends of the arc-shaped tube.

[0012] Furthermore, a support leg is fixedly installed at the bottom of the water pump, and a support ring is fixedly installed at the bottom of the support leg.

[0013] Furthermore, the top of the support ring has mounting holes arranged in a ring at equal intervals, and the mounting holes are countersunk holes. The outer edges of the ring-shaped box and the support ring are all rounded.

[0014] Furthermore, the sealing mechanism includes an inner frame, which is fixedly installed inside the annular box. An electric push rod is fixedly installed at the bottom of the inner frame, and a connecting shaft is fixedly installed at the top of the electric push rod. Hangers are fixedly installed at equal intervals in a ring at the top of the connecting shaft. A sealing plate is fixedly installed at the outer end of the hanging frame. After the sealing plate is lowered, it is respectively positioned on one side of the coarse grading filter plate, the medium grading filter plate, the small grading filter plate, and the micro grading filter plate at the corresponding positions.

[0015] Furthermore, the drainage module includes drainage hoppers, which are arranged in a ring at equal intervals and fixedly installed at the bottom of the ring-shaped box. The top of each drainage hopper is connected to the bottom of the corresponding fish tank. A drainage and fish discharge pipe is fixedly connected to the outer end of each drainage hopper, and a sealing cap is threaded to the outer end of the drainage and fish discharge pipe. Anti-slip grooves are arranged in a ring at equal intervals on the outer surface of the sealing cap.

[0016] The beneficial effects of this utility model are:

[0017] 1. During the application of this technical solution, by setting up multi-group graded filter plates and a vortex drive mechanism, a vortex can be generated in the annular box during use. This causes the bass fry to move with the water flow and pass through the filter plates with different mesh sizes, thereby achieving automatic grading of fry of different sizes. This achieves the effect of accurately separating fry of different sizes, solving the problem that existing fry farming devices cannot grade and can only be mixed, resulting in the squeezing of the living space for small fry. At the same time, the setting of the sealing mechanism can flexibly control the connection and separation of the fish farming chamber. It can be opened during grading to allow the fry to flow, and closed after grading to prevent the fry from mixing, further ensuring the grading effect and avoiding the defect of easy mixing of fry after grading in existing technologies. This meets the basic needs of refined bass fry farming.

[0018] 2. During the application of this technical solution, the coordinated operation of the drainage module and the vortex drive mechanism allows for convenient transfer of graded fish fry and daily water exchange operations. Regularly activating the vortex drive mechanism can also maintain water flow to increase dissolved oxygen levels and improve the aquaculture environment, thereby reducing the difficulty of aquaculture management and improving the convenience of aquaculture. This solves the problems of inconvenient fish fry transfer and easy deterioration of the aquaculture environment in existing technologies. In addition, after each fish tank is independent, the feeding plan can be adjusted for fish fry of different sizes, avoiding the situation of large fish fry competing for food and small fish fry not getting enough food caused by mixed culture in existing technologies. This meets the requirements of industrialized sea bass farming, improves the quality and survival rate of fish fry, and solves the problem of poor adaptability of existing devices.

[0025] 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.

[0026] Example 1

[0027] A grading box for intensive sea bass farming includes an annular box 1. Inside the annular box 1, coarse grading filter plates 2, medium grading filter plates 3, small grading filter plates 4, and micro grading filter plates 5 are arranged and fixedly installed in a ring at equal intervals. A sealing mechanism 6 is fixedly installed in the center of the annular box 1, with its sealing ends covering one side of each of the filter plates. Swirl drive mechanisms 7 are fixedly installed at equal intervals on the outer side of the annular box 1, with both the input and output ends connected to the inside of the annular box 1. The annular box 1 is divided into four fish tanks 8 by coarse grading filter plates 2, medium grading filter plates 3, small grading filter plates 4, and micro grading filter plates 5. A drainage module 9 is fixedly installed at the bottom of the annular box 1, and the top of the drainage module 9 is connected to the bottom of the fish tank 8. During the application of this device, the coarse grading filter plates 2, medium grading filter plates 3, small grading filter plates 4, and micro grading filter plates 5 inside the annular box 1, as well as the sealing mechanism 6 in the middle, the vortex drive mechanism 7 on the outside, and the drainage module 9 at the bottom, allow the bass fry to be graded to be placed into the annular box 1 first. In the initial state, the sealing mechanism... The sealing end of the 6 mechanism covers one side of each graded filter plate, keeping the four fish tanks 8 separated by the box independent and preventing the fry from mixing prematurely. When grading is required, the sealing end of the sealing mechanism 6 is removed from each graded filter plate, connecting the four fish tanks 8. Then, the vortex drive mechanism 7 is activated, using its input and output ends connected to the annular box 1 to drive the water in the box to flow, causing the fry to move with the water flow. During this process, fry of different sizes will be separated into different fish tanks 8 due to the filtration effect of each graded filter plate. The largest fry cannot pass through the coarse grading filter plate 2, while smaller fry cannot. Smaller fry pass through coarse grading filter plate 2, medium grading filter plate 3, etc., to achieve grading of fry of different sizes. After grading, the fry in different fish tanks 8 can be discharged separately through drainage module 9 to meet the needs of subsequent breeding. This design can effectively avoid the problem of competition for living space that may occur when fry of different sizes are mixed, allowing fry of each size to grow in their corresponding fish tank 8. At the same time, the water flow driven by vortex drive mechanism 7 can also provide a more suitable growth environment for fry. Drainage module 9 facilitates the subsequent transfer of fry, thus improving the efficiency and convenience of fry grading in sea bass factory farming.

[0028] Combination Figures 1-4As shown, the vortex drive mechanism 7 includes arc-shaped tubes 71, which are arranged in a ring at equal intervals and fixedly installed on the outside of the annular box 1. The input and output ends of each arc-shaped tube 71 are connected to the inside of the fish tank 8 at the corresponding position. A water pump 72 is fixedly installed in the middle of the outer side of the arc-shaped tube 71. The input and output ends of the water pump 72 are connected to the inside of the fish tank 8 through the arc-shaped tubes 71. Fish-proof filter screens 73 are fixedly installed at both ends of the arc-shaped tubes 71. The fish-proof filter screens 73 are set to cover the input and output ends of the arc-shaped tubes 71. A support leg 74 is fixedly installed at the bottom of the water pump 72. A support ring 75 is fixedly installed at the bottom of the support leg 74. The top of the support ring 75 has mounting holes 76 arranged in a ring at equal intervals. The mounting holes 76 are countersunk holes. The outer surface corners of the annular box 1 and the support ring 75 are rounded.

[0029] In the above-described embodiments of this application, during the application of this device, the vortex drive mechanism 7 includes an arc-shaped tube 71, a water pump 72, a fish-proof filter 73, a support leg 74, a support ring 75, and a mounting hole 76. This allows the device to be fixed in a suitable position using the mounting hole 76 at the top of the support ring 75. The countersunk hole design ensures that the fasteners remain flat after installation, preventing protrusions from affecting operation. When it is necessary to drive the water flow within the annular tank 1, the water pump 72 at the middle of the outer side of the arc-shaped tube 71 is activated. The water pump 72 draws water from the corresponding fish tank 8 through the input end of the arc-shaped tube 71 and then returns the water to the fish tank 8 through the output end, forming a circulating water flow. Because the arc-shaped tubes 71 are arranged in a ring with equal spacing, they can drive the water in the tank to form a stable vortex. During this process, the fish-proof filters at both ends of the arc-shaped tube 71... Fish filter 73 covers the inlet and outlet ends, preventing fish fry from entering the arc-shaped pipe 71 and protecting them from damage by the water pump 72 or pipe blockage, ensuring smooth water circulation. Simultaneously, the support leg 74 at the bottom of the water pump 72 cooperates with the support ring 75 to provide stable support for the pump, preventing displacement due to vibration during operation. The rounded edges on the outer surfaces of the annular housing 1 and the support ring 75 prevent operators from being scratched by sharp edges when approaching or operating the device. This design not only efficiently drives the water to form a vortex, meeting the water flow conditions required for fish fry grading, but also protects the fish fry through the anti-entry fish filter 73. The support structure ensures stable operation of the device, and the rounded edges enhance operational safety. Overall, this design guarantees the reliable implementation of the vortex drive function, improving safety and convenience during use.

[0030] Example 2

[0031] Combination Figures 3-5As shown, the sealing mechanism 6 includes an inner frame 61, which is fixedly installed inside the annular box 1. An electric push rod 62 is fixedly installed at the bottom of the inner frame 61, and a connecting shaft 63 is fixedly installed at the top of the electric push rod 62. A hanger 64 is fixedly installed at the top of the connecting shaft 63 in a ring at equal intervals. A sealing plate 65 is fixedly installed at the outer end of the hanger 64. After the sealing plate 65 is lowered, it is respectively set on one side of the coarse grading filter plate 2, medium grading filter plate 3, small grading filter plate 4 and micro grading filter plate 5 at the corresponding positions. The drainage module 9 includes a drainage hopper 91, which is fixedly installed at the bottom of the annular box 1 in a ring at equal intervals. The top of the drainage hopper 91 is connected to the bottom of the fish tank 8 at the corresponding position. A drainage and fish discharge pipe 92 is fixedly connected to the outer end of the drainage hopper 91. A sealing cap 93 is threadedly connected to the outer end of the drainage and fish discharge pipe 92. Anti-slip grooves 94 are arranged in a ring at equal intervals on the outer surface of the sealing cap 93.

[0032] The technical solutions described in the embodiments of this application, during the application of this device, through the setting of the sealing mechanism 6 including the internal frame 61, electric push rod 62, connecting shaft 63, hanging frame 64, and sealing plate 65, and the drainage module 9 including the drainage hopper 91, drainage and fish discharge pipe 92, sealing cover 93, and anti-slip groove 94, allow for flexible control of the connection and independent state of the fish tank 8 according to the grading requirements of the fish fry, while conveniently completing the transfer of fish fry and water discharge. When grading is not required, the electric push rod 62 can drive the connecting shaft 63 and hanging frame 64 to move, causing the sealing plate 65 to descend to the side of the coarse grading filter plate 2, medium grading filter plate 3, small grading filter plate 4, and micro grading filter plate 5 at the corresponding positions, separating the various fish tanks 8 in the annular box 1, avoiding the mixing of fish fry in different areas, and providing independent growth space for fish fry of different sizes; when grading or transferring fish fry is required, the electric push rod 62 The sealing plate 65 is moved away from the filter screen plate, allowing the fish tanks 8 to connect and facilitate the flow of fish fry within the tanks for grading, or for transfer via the drainage module 9. When draining or transferring fish fry, the sealing cap 93 at the outer end of the drainage and fish discharge pipe 92 is opened. The water and fish fry in the fish tank 8 can flow into the drainage and fish discharge pipe 92 through the drainage hopper 91 at the bottom, and then be discharged from the drainage and fish discharge pipe 92. The anti-slip groove 94 on the outer surface of the sealing cap 93 allows the operator to more easily twist the sealing cap 93, avoiding hand slippage that affects operating efficiency. This design not only enables flexible switching of the state of the fish tank 8 through the sealing mechanism 6 to meet the different needs before and after fish fry grading, but also simplifies the process of water replacement and fish fry transfer through the drainage module 9. The anti-slip groove 94 also improves the ease of operation. Overall, it provides stable and efficient support for fish fry management in sea bass factory farming, ensuring the smooth progress of the farming process.

[0033] The working principle and advantages of this utility model are as follows: Before using this device for grading and raising sea bass fry, the entire device is first fixed in the designated factory farming area using fasteners through the mounting holes 76 at the top of the support ring 75. The support ring 75 provides bottom support for the entire grading box, ensuring stability when the device is placed. The support leg 74 connects the water pump 72 to the support ring 75, thereby ensuring that the water pump 72 can be maintained at a suitable working height. The outer surface edges of the annular box 1 are rounded to prevent operators from being scratched during daily operations. Next, it is confirmed that the sealing caps 93 at the outer ends of each drainage and fish discharge pipe 92 in the drainage module 9 are tightened. The anti-slip grooves 94 on the outer surface of the sealing cap 93 facilitate the operator's grip and rotation, ensuring a good seal between the sealing cap 93 and the drainage and fish discharge pipe 92, thereby preventing leakage of aquaculture water. At the same time, the sealing mechanism 6 is confirmed to be tightened. In the initial working state, the sealing plate 65, under the action of the electric push rod 62, covers one side of the coarse grading filter plate 2, the medium grading filter plate 3, the small grading filter plate 4, and the micro grading filter plate 5 respectively, making the four fish tanks 8 formed by these filter plates in the annular box 1 independent of each other. The internal frame 61 provides installation support for the electric push rod 62. The electric push rod 62 is connected to the hanger 64 through the coupling 63, which can drive the coupling 63 to move up and down. The hanger 64 fixes the sealing plate 65 so that the sealing plate 65 can move synchronously with the coupling 63. After these preparations are completed, the release port of the annular box 1 is opened, and the bass fry to be graded are put into the fish tank 8 near the coarse grading filter plate 2. At this time, due to the obstruction of the sealing plate 65, the fry cannot enter other fish tanks 8, ensuring that the fry are concentrated in the designated area during the initial release. After the release is completed, the release port is closed.

[0034] Then, the sealing mechanism 6 is activated, controlling the electric push rod 62 to start. The electric push rod 62 drives the connecting shaft 63 to move upward, and the connecting shaft 63 drives the sealing plate 65 to move upward synchronously through the hanger 64 until the sealing plate 65 is completely separated from one side of each grading filter plate, so that the four fish tanks 8 are connected through each filter plate, creating conditions for the flow and grading of fish fry. Next, the vortex drive mechanism 7 is activated, starting the water pump 72 in the middle of the outer side of each arc-shaped pipe 71. The water pump 72 draws water from the fish tank 8 through the input end of the arc-shaped pipe 71, and then sends the water back to the fish tank 8 through the output end to form a circulating water flow. Because the arc-shaped pipes 71 are arranged in a ring on the outside of the annular box 1 and each water pump 72 works synchronously, the water flow in the annular box 1 forms a vortex state. The anti-fish-entry filter screens 73 at both ends of the arc-shaped pipes 71 cover the input and output ends, preventing the bass fry from entering the arc-shaped pipes 71 and avoiding the fish fry from entering the interior of the arc-shaped pipes 71. The pipes are damaged or blocked by the water pump 72; under the action of swirling flow, the bass fry in the annular box 1 move with the water flow. As the mesh diameter of the coarse grading filter plate 2, medium grading filter plate 3, small grading filter plate 4 and micro grading filter plate 5 decreases in sequence, the largest bass fry cannot pass through the coarse grading filter plate 2 and is intercepted in the initial fish tank 8. The next largest bass fry can pass through the coarse grading filter plate 2 but cannot pass through the medium grading filter plate 3 and is intercepted in the adjacent fish tank 8. The next smallest bass fry can pass through the coarse grading filter plate 2 and the medium grading filter plate 3 but cannot pass through the small grading filter plate 4 and is intercepted in the third fish tank 8. The smallest bass fry can pass through the first three grading filter plates in sequence and is finally intercepted in the fourth fish tank 8 near the micro grading filter plate 5. Thus, the grading operation of bass fry of different sizes is completed.

[0035] After grading, first turn off all water pumps 72 to stop the swirling flow in the annular tank 1 and restore the water flow to a stable state, preventing the fish fry from moving further during subsequent operations. Then, control the electric push rod 62 to start in reverse. The electric push rod 62 drives the connecting shaft 63 to move downwards. The connecting shaft 63 drives the sealing plate 65 to move downwards synchronously through the hanger 64 until the sealing plate 65 covers one side of each grading filter plate again, separating the four fish tanks 8 into independent spaces to prevent the graded fish fry from mixing again. After that, proceed with subsequent operations according to the breeding needs. If it is necessary to separate the graded fish fry... When fish fry are transferred to other aquaculture devices, the sealing cap 93 at the outer end of the drainage and fish discharge pipe 92 at the bottom of the corresponding fish tank 8 can be unscrewed. The fish fry and some aquaculture water can be discharged together into a designated container or device through the drainage and fish discharge pipe 92. If it is necessary to continue aquaculture in this device, the sealing cap 93 can be kept closed, and aquaculture operations such as feeding and water changing can be carried out directly in each independent fish tank 8. The drainage hopper 91 is fixed to the bottom of the ring-shaped box 1 and its top is connected to the bottom of the fish tank 8. It can guide the water and fish fry in the fish tank 8 to flow smoothly into the drainage and fish discharge pipe 92, which facilitates drainage and fish discharge operations.

[0036] During daily aquaculture, the water pump 72 can be started periodically to keep the water in the annular tank 1 flowing. The flowing water increases dissolved oxygen levels, improving the aquaculture environment. Furthermore, since each fish tank 8 is independent, the farmer can adjust the feeding amount and feed specifications according to the size of the fry in each tank 8, ensuring that each fry receives sufficient and suitable food. This technical solution solves the problem of existing devices being unable to grade and raise fry of different sizes by setting up multi-group tiered filter plates and a vortex drive mechanism 7, avoiding the situation where small fry are squeezed out of their living space; the sealing mechanism 6 and... The use of drainage module 9 not only ensures that the graded fry will not mix again, but also facilitates the transfer of fry and daily aquaculture management, reduces the difficulty of aquaculture management, and improves work efficiency. At the same time, the annular box 1 provides a stable aquaculture space, and the support ring 75 ensures the overall stability of the device. The coordinated work of each structure meets the requirements of large-scale and refined industrialized sea bass farming, meets the growth needs of sea bass fry of different sizes, avoids the problem of large fry competing for food and small fry not getting enough food due to mixed farming, improves the farming quality and survival rate of sea bass fry, and solves the problem of poor adaptability of existing devices in sea bass farming.

[0037] In this technical solution, the electric actuator 62 is a DTZ300 DC electric actuator 62 with a rated voltage of 12V-24V and a rated thrust of 300N-500N; the water pump 72 is an MP-150R miniature submersible pump 72 with a rated voltage of 12V-24V and a rated flow rate of 150L / h-200L / h; the controller is an STM32F103C8T6 microcontroller controller, installed in a protective box in the middle of the outer side of the ring-shaped enclosure 1. The controller is equipped with a 128×64 dot matrix OLED display. The circuit connection is as follows: external 220V AC power is converted to 24V DC power through an AC-DC-24V-5A switching power supply, which powers the controller, electric actuator 62, and water pump 72 respectively. The controller's I / O... The pins are connected to the motor drive module (model L298N) of the electric actuator 62, the relay module of the water pump 72, the display screen, and the encoder, respectively. Both the electric actuator 62 and the water pump 72 are equipped with E6B2-CWZ6C encoders. The encoder output is connected to the controller, enabling motor rotation adjustment and stepless speed regulation. During use, depending on specific application requirements, DS18B20 temperature sensors can be installed in each fish tank 8 for real-time monitoring of the aquaculture water temperature; YF-S201 flow sensors can be installed at the drainage and fish discharge pipe 92 for monitoring drainage flow; and DO-6800 dissolved oxygen sensors can be installed in the annular box 1 for monitoring dissolved oxygen levels in the water. The outputs of each sensor are connected to the controller for data acquisition and control. Heaters can also be added as needed to assist in regulating water temperature.

[0038] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0039] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
