Description

Technical Field

[0001] This utility model relates to the field of aquaculture, specifically to an intelligent breeding box for grouper fry. Background Technology

[0002] Grouper fry refer to the early growth stage of grouper from hatching to adulthood. During this stage, the fish have high environmental requirements and are extremely sensitive to conditions such as water quality, temperature, and dissolved oxygen. They also have weak disease resistance, so they need to be carefully managed. A breeding tank is a closed or semi-closed container used for aquaculture, which can provide a stable growth environment for fish.

[0003] In the prior art, a fish fry rearing box disclosed in patent publication number "CN221843515U" solves the problems mentioned in the background art. The rearing box includes a support plate connected to its side wall, a water tank connected to the top of the support plate, a transition box on the support plate, a drain pipe connected to the bottom of the water tank, a valve on the drain pipe, a nozzle at the bottom of the drain pipe, a baffle on the transition box, a handle on the top of the baffle, multiple overflow pipes on the side wall of the baffle, an installation groove on the transition box, a waterproof coating inside the installation groove, a fixed connection between the baffle and each overflow pipe, and an inclined end face of each overflow pipe. The rearing box and the transition box are both fixedly connected to the support plate.

[0004] However, existing technologies still have significant shortcomings:

[0005] 1. Traditional grouper fry need to be manually screened for fry that do not meet the size requirements before they are raised in traditional breeding boxes. This is extremely inefficient and cannot meet the needs of large-scale breeding.

[0006] 2. Traditional fish tanks make it difficult to accurately determine the number of fish fry, which can easily lead to unreasonable stocking density and make it difficult to accurately calculate the amount of feed, medicine, etc. required.

[0007] 3. Traditional breeding boxes cannot effectively classify fish fry by size, resulting in mixed breeding of fish fry of different sizes, causing uneven growth competition, affecting overall development, and making management difficult. Utility Model Content

[0008] The purpose of this invention is to provide an intelligent grouper fry breeding box to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an intelligent grouper fry rearing box, including a rearing machine box, with a placement opening through the top surface of the rearing machine box, a screening container embedded in the placement opening, and the screening container and the placement opening cooperating with each other, and the screening container is a hexagonal conical container, with a rotating sorting disc on the bottom surface of the screening container, a guide plate installed inside the rearing machine box, a rotating rod connected to the bottom surface of the guide plate, rearing containers fixed on both sides inside the rearing machine box, and visual acquisition devices provided near both ends of the guide plate, and the visual acquisition devices are fixed to the inner wall of the rearing machine box with screws.

[0010] As can be seen, in the above technical solution, the aquaculture machine can achieve efficient screening of grouper fry. During the screening process, the water flow and filter outlet are used to discharge fry that are not up to size, allowing the fry to slide down the guide plate into the corresponding aquaculture container. Furthermore, the number of fry is collected and counted by a visual camera, and the tilt direction of the guide plate is adjusted so that fry of the correct size can fall smoothly into the qualified fry aquaculture container, thereby achieving the function of classified aquaculture.

[0011] Preferably, the top surface of the rotating sorting disc is in contact with the bottom surface of the screening container, and the rotating sorting disc is movably connected to the bottom surface of the screening container.

[0012] As can be seen, in the above technical solution, the rotating sorting disc can be rotated and adjusted to rotate the appropriate rotating sorting disc to the outlet of the screening container for seedling screening.

[0013] Preferably, the two ends of the rotating rod are connected to a rotary motor, and the two rotary motors are fixed to the front and back of the breeding box, respectively.

[0014] As can be seen, in the above technical solution, a rotary motor can be used to drive the rotating rod and guide plate to rotate, so that the guide plate tilts to classify larger or smaller seedlings.

[0015] Preferably, a limiting bracket is bolted between the two aquaculture containers, and the rotating rod is connected to the through-hole bearing at the center of the limiting bracket.

[0016] As can be seen, in the above technical solution, adding a limiting bracket can limit and install the rotating rod, providing good support and stability for the rotating rod structure.

[0017] Preferably, the two ends of the guide plate are far away from the two sides inside the breeding machine box, and the guide plate is rectangular, with both sides of the guide plate fitting against the two sides inside the breeding machine box.

[0018] As can be seen, in the above technical solution, there are gaps between the two ends of the guide plate and the two sides inside the breeding machine box, which makes it easy for the seedlings to slide down the guide plate to the corresponding breeding container. Furthermore, the tilting of the two ends of the guide plate can ensure that the seedlings slide into the container.

[0019] Preferably, an aerator is provided between the two aquaculture containers, and the aerator is connected to an aeration pipe at its connecting end, with the aeration end of the aeration pipe located inside the aquaculture container.

[0020] As can be seen, in the above technical solution, the aeration pipe combined with the aerator can perform aeration treatment in the aquaculture container.

[0021] Preferably, a spray pipe is provided on the top surface of the placement port, and filter cylinders are fixed on both the front and back of the breeding machine box, with the connection end of the spray pipe connected to the outlet flange of the filter cylinder.

[0022] As can be seen, in the above technical solution, the water pump inside the filter can extract the liquid and spray it from the spray pipe to the inner wall of the screening container. When adding water to the breeding container, it is only necessary to adjust the position of the guide plate so that the water sprays out through the guide plate and flows into the corresponding breeding container.

[0023] Preferably, the front and back interfaces of the breeding machine box are connected to filter heads, and the interface of the filter cylinder is connected to a circulation pipe, and the outlet end of the circulation pipe is connected to the inlet end of the filter cylinder. The openings on both sides of the breeding machine box are provided with sealing covers.

[0024] As can be seen, in the above technical solution, the filter head can filter the water in the breeding container to prevent the seedlings from being pulled out. After the water enters the filter cylinder, it can be filtered and recycled through the internal filter element to improve the water quality environment in the breeding container.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By adjusting the rotating disc at the bottom of the container with filter holes, efficient screening of grouper fry can be achieved. During the screening process, water flow and the filter outlet discharge fry that do not meet the size requirements, allowing the fry to slide down the guide plate into the corresponding rearing container. The number of fry is collected by a visual camera, which not only improves the accuracy of screening but also allows for precise counting of fry. This helps farmers to keep track of the number and growth of fry in a timely manner, facilitating accurate calculation of the amount of feed, medicine, etc. required in later rearing. When fry that meet the size requirements are discharged for rearing, the rotation of the rotating disc and the adjustment of the guide plate tilt direction allow fry of the appropriate size to fall smoothly into the appropriate fry rearing container. The number is also collected by a visual camera, realizing automated aquaculture management. Before rearing, the fry can be classified by size using the fry screening structure built into the rearing machine, thereby achieving the effect of classified rearing, greatly improving aquaculture efficiency and reducing labor costs.

Detailed Implementation

[0035] 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.

[0036] Please see Figure 1-7 This utility model provides a technical solution:

[0037] Example 1: A smart grouper fry rearing box: It includes a rearing box 1, with a placement opening 2 extending through the top surface of the rearing box 1. A screening container 3 is embedded within the placement opening 2, and the screening container 3 and placement opening 2 are mutually compatible. The screening container 3 is a hexagonal conical container located within the placement opening 2. The shape and size of the screening container 3 and placement opening 2 correspond to each other. Before the fry are placed into the rearing box 1 for rearing, they need to enter the screening container 3. The screening container 3, being a hexagonal conical container, serves as the starting container for the grouper fry entering the screening process. Its hexagonal design may facilitate a rational layout of space, and the conical structure helps guide the fry to flow smoothly downwards. Simultaneously, the conical structure, combined with the symmetry of the hexagon, allows the water flow to naturally concentrate towards the center or a specific direction, reducing physical damage to the fry caused by collisions with the container edges during drainage. The conical bottom accelerates water collection and drainage, shortening drainage time and improving operational efficiency. The bottom surface of the device 3 is equipped with a rotating sorting disc 4. The top surface of the rotating sorting disc 4 is in contact with the bottom surface of the screening container 3, and the rotating sorting disc 4 is movably connected to the bottom surface of the screening container 3. It is worth noting that there are two or more sets of rotating sorting discs 4. A motor is added at the center position to rotate multiple sets of rotating sorting discs 4, realizing the interchange of positions, so that the required rotating sorting disc 4 is located at the bottom of the screening container 3, aligned with the outlet, waiting for sorting. Similarly, after adjusting its position, the rotating sorting disc 4 can be staggered with the bottom opening of the screening container 3, so that the opening can be opened directly, making it convenient to discharge the screened fry directly. By adjusting the position of the rotating sorting disc 4, it can be aligned with the bottom opening of the hexagonal cone container to achieve the screening of fry of different sizes. When the rotating sorting disc 4 is aligned with the bottom opening of the screening container 3, unqualified small fry can be screened out. When the rotating sorting disc 4 is staggered with the bottom opening of the screening container, qualified fry can pass through, realizing a flexible and efficient fry screening function.

[0038] Inside the aquaculture housing 1, a guide plate 5 is installed. The two ends of the guide plate 5 are far from the sides of the aquaculture housing 1, and the guide plate 5 is rectangular. Both sides of the guide plate 5 are flush with the sides of the aquaculture housing 1. A rotating rod 7 is connected to the bottom of the guide plate 5. Aquaculture containers 10 are fixed to both sides of the aquaculture housing 1. The guide plate 5 provides a channel for the fish fry to slide down. When unqualified fish fry are screened, they slide down its inclined surface into the small fry aquaculture container 10. When qualified fish fry are screened, after adjusting the tilt direction, the qualified fish fry can fall into the qualified fry aquaculture container 10 along the opposite tilt direction, thus guiding the fish fry to different aquaculture areas. The rotation of the rotating sorting disc 4 adjusts the size of the filter holes. Align the bottom opening of the screening container 3 with the seedlings. At this point, smaller seedlings, along with the water flow, will be discharged from the filter holes and fall onto the guide plate 5 below. The guide plate 5 is pre-set to tilt towards the left side of the rearing container 10. The seedlings will then slide down the tilted surface of the guide plate 5 into the rearing container 10. Larger or qualified seedlings will remain in the screening container 3. Then, the rotating sorting disc 4 is aligned with the bottom opening of the screening container 3, and the guide plate 5 is tilted towards the right side of the rearing container 10. The seedlings will then be discharged from the bottom opening of the screening container 3 and fall into the right-hand rearing container 10 along the guide plate 5. This achieves seedling size screening and automatic classification rearing.

[0039] Visual acquisition devices 6 are installed near both ends of the guide plate 5, and are fixed to the inner wall of the aquaculture machine box 1 with screws. Visual acquisition devices 6, which are visual acquisition cameras, are added to the top of both ends of the guide plate 5. These devices count the number of fry as they slide down the guide plate 5. Whether the fry are defective or qualified, the number can be counted, providing accurate fry quantity information for aquaculture personnel. This facilitates scientific management and monitoring of the aquaculture process, allowing for accurate understanding of the fry quantity. Based on the size of the aquaculture site and water quality conditions, the stocking density can be rationally determined, avoiding problems such as insufficient growth space, water quality deterioration, and easy disease transmission due to overcrowding, or waste of resources due to undercrowding. Furthermore, by knowing the number of fry, the required amount of feed and medicine can be accurately calculated, and fish yield can be estimated. It is worth noting that the fry... The process for quantification is as follows: Visual acquisition device 6 is a visual camera installed on top of the guide plate. It can capture the dynamic process of fish fry sliding down in real time. The camera is usually equipped with high frame rate and high resolution to ensure that it can clearly capture fast-moving fish fry. Through computer vision algorithms such as deep learning-based target detection models, the system can identify fish fry targets in images or videos. The algorithm will distinguish between fish fry and background and mark the position and outline of each fish fry. Using multi-frame image analysis, the system can track the movement trajectory of the fish fry and determine whether the fish fry have passed through the sliding channel. Through trajectory analysis, double counting or omission can be avoided. At the same time, based on the number of detected fish fry targets and movement trajectories, the total number of fish fry that have fallen down is counted in real time. Whether the fish fry are qualified or unqualified, they will be included in the statistics. The statistical results will be transmitted to the aquaculture management system in real time to provide aquaculture personnel with accurate fish fry quantity information, which will facilitate subsequent management work such as stocking density planning, feed feeding, and yield prediction.

[0040] Example 2:

[0041] Based on Embodiment 1, the two ends of the rotating rod 7 are connected to rotary motors 8, and the two rotary motors 8 are fixed to the front and back of the breeding box respectively. A limiting bracket 9 is bolted between the two breeding containers 10, and the rotating rod 7 is connected to the through-hole bearing at the center of the limiting bracket 9. The bottom of the guide plate 5 is directly connected to the rotating rod 7. Rotary motors 8 are added to both ends of the rotating rod 7. When the rotary motors 8 work, the rotating rod 7 and the guide plate 5 can rotate together to complete the tilt adjustment of the guide plate 5. At the same time, the limiting bracket 9 on the surface of the rotating rod 7 plays the role of limiting and installing the rotating rod 7, which improves the stability of the rotating mechanism.

[0042] An aerator 11 is installed between two aquaculture containers 10. The aerator 11 is connected to an aeration pipe 12, and the aeration end of the aeration pipe 12 is located inside the aquaculture container 10. Both sides of the aquaculture container 10 are equipped with aeration pipes 12 for aquaculture. The aerator 11 compresses air to aerate the aquaculture container 10. The aerator 11 can be a Roots blower that pressurizes air and delivers gas to the aeration end, generating a large number of microbubbles. These bubbles rise slowly in the water, significantly increasing the dissolved oxygen content of the water and enhancing the water flow.

[0043] A spray pipe 15 is provided on the top surface of the placement port 2. Filter cylinders 14 are fixed on both the front and back of the breeding machine box 1. The connection end of the spray pipe 15 is connected to the outlet flange of the filter cylinder 14. The spray end of the spray pipe 15 is hexagonal, and the spray nozzles are all facing the inner wall of the screening container 3. The spray is controlled by connecting the pipe and flange to the outlet of the filter cylinder 14. Valves and flow meters are added to continuously send water into the screening container 3.

[0044] Filter heads 17 are connected to the interfaces on the front and back of the breeding machine casing 1, and a circulation pipe 16 is connected to the interface of the filter cylinder 14. The outlet end of the circulation pipe 16 is connected to the inlet end of the filter cylinder 14. The circulation pipe 16 connects the filter head 17 to the filter cylinder 14. The filter head 17 is threadedly connected to the outlet of the breeding container 10. The filter head 17 uses a water pump to draw the liquid in the breeding container 10 into the filter cylinder 14. The water is filtered by the filter element inside the filter cylinder 14 and sprayed out again from the spray pipe 15. The filtered water is then sent back to the filter cylinder 14 by the tilting of the guide plate 5. Inside the corresponding breeding container 10, the filter head 17 can filter the water inside the breeding container 10 to prevent the fry from being pulled out. After the water enters the filter cylinder 14, it can be filtered and recycled through the internal filter core to improve the water quality environment inside the breeding container 10. The openings on both sides of the breeding machine box 1 are equipped with sealing covers 13. When it is necessary to take out the fry in the breeding container 10 later, the sealing covers 13 can be taken out. The sealing covers 13 are engaged with the openings on both sides of the breeding machine box 1. Both the sealing covers 13 and the openings are equipped with sealing rubber gaskets. After the two are inserted and engaged, they can be sealed by aligning the rubber gaskets.

[0045] Working Principle: The breeding box 1 is the casing of the grouper fry breeding box. The top and front of the breeding box 1 have control panels for the equipment, allowing direct parameter control and start / stop control of the equipment. The screening container 3 is located inside the placement opening 2. The shape and size of the screening container 3 and the placement opening 2 correspond to each other. The screening container 3 is a hexagonal conical container. Before the fry are placed into the breeding box 1 for breeding, they must be placed into the screening container 3. By rotating the sorting disc 4, the required filter hole size is aligned with the bottom opening of the screening container 3. At this time, smaller fry, along with the water flow, are discharged from the filter holes and fall onto the guide plate 5 below. The guide plate 5 is pre-set to tilt. The guide plate 5 is tilted so that one end is tilted towards the left side of the breeding container 10. At this time, the seedlings slide down the tilted surface of the guide plate 5 into the breeding container 10. Seedlings that are larger or of acceptable size after screening are retained in the screening container 3. Then, the rotating sorting plate 4 is intersected with the bottom opening of the screening container 3, and the tilting direction of the guide plate 5 is tilted towards the right side of the breeding container 10. The seedlings are discharged from the bottom opening of the screening container 3 and fall into the right side of the breeding container 10 for breeding, thus realizing the size screening of seedlings and the automatic classification breeding function. Visual acquisition devices 6 are added to the top of both ends of the guide plate 5. The visual acquisition devices 6 are visual acquisition cameras, which can count the number of seedlings when they slide down the guide plate 5.
