Description

Technical Field

[0001] This utility model relates to the field of intelligent fish feeding technology, specifically a novel intelligent fish feeding system. Background Technology

[0002] Zebrafish (Danio rerio) have become important model organisms for vertebrates and common tropical ornamental fish due to their gentle temperament, strong gregariousness, small size, low breeding costs, short reproductive cycle, high egg production, and their genome's high similarity to humans (approximately 87%). In laboratory animal applications, the larval stage is particularly crucial, and the selection and management of feed are core factors determining their growth, development, gonadal maturation time, and overall health. Studies have shown that live food (such as brine shrimp) can significantly promote zebrafish growth and gonadal development, effectively shortening the sexual maturity cycle.

[0003] Currently, zebrafish farming (especially in large-scale laboratory settings) commonly employs manual feeding. The specific procedure typically involves placing dry feed or hatched brine shrimp in a wash bottle (or similar squeeze bottle), mixing it thoroughly with water, and then dispensing it through the feeding holes in the tank cover. This traditional method has the following significant drawbacks:

[0004] (1) Poor feeding accuracy and high randomness. The amount of feed is entirely dependent on the operator's personal experience for estimation, lacking quantitative standards, resulting in a large randomness in the amount of feed (sometimes more and sometimes less), making it impossible to achieve precise nutrition supply.

[0005] (2) Low operational efficiency and high labor intensity. Zebrafish farming is usually large-scale. A standard single-row breeding rack can accommodate 60 breeding tanks, while a double-row rack can accommodate up to 120 tanks. Large-scale breeding facilities may have dozens of fish racks, corresponding to thousands of breeding units. Zebrafish need to be fed 2-3 times a day. At this scale, manual feeding of each tank is extremely time-consuming, becoming the main labor bottleneck in breeding work.

[0006] (3) It can easily lead to overfeeding, causing multiple negative effects:

[0007] 1) Feed waste: Excessive feed not being consumed directly increases the laboratory's operating costs.

[0008] 2) Water pollution: Residual feed decomposes in the water, consuming dissolved oxygen and producing harmful metabolites such as ammonia nitrogen, leading to water quality deterioration (such as eutrophication).

[0009] 3) Increased water treatment load: Deteriorating water quality significantly increases the operational burden on circulating water treatment systems (such as biological filters, protein skimmers, etc.), shortens the lifespan of filter media, increases maintenance frequency and cost, and may endanger the health of fish. Summary of the Invention

[0010] This invention aims to solve the problems of inaccurate feeding amount, high labor cost, and easy overfeeding leading to feed waste and water pollution in traditional zebrafish feeding methods. It provides a new type of intelligent fish feeding system that can accurately feed zebrafish at fixed times and in fixed quantities, saves labor, and can match the needs of zebrafish populations.

[0011] To achieve the above objectives, this utility model provides the following technical solution: A novel intelligent fish feeding system, comprising a fish rack, wherein several supporting crossbeams are fixedly installed inside the fish rack, and several fish tanks are fixedly installed at the top of each of the supporting crossbeams. A water tank is fixedly installed at the bottom of the inner wall of the fish rack. An operation box is fixedly installed on one side of the fish rack, and an operation panel is fixedly installed at the top of the front of the operation box. A partition is fixedly installed inside the operation box, and the operation box is divided into a motor chamber and a feeding chamber from top to bottom by the partition. A feeding assembly is fixedly installed inside the feeding chamber. The feeding assembly includes a stirring beaker and a peristaltic pump. The inlet of the peristaltic pump is fixedly connected to a water injection hose for the stirring beaker. A feed cylinder connecting valve is fixedly installed in the middle of the water injection hose for the stirring beaker. The end of the water injection hose for the stirring beaker away from the peristaltic pump is fixedly connected to the inlet and outlet of the stirring beaker on the surface of the stirring beaker. The outlet of the peristaltic pump is fixedly connected to a feed delivery hose. A magnetic stirrer is fixedly installed at the bottom of the stirring beaker.

[0012] Preferably, the bottom end of the magnetic stirrer is fixedly connected to the feeding chamber, the top end of the stirring beaker is fixedly connected to a connecting pipe, two symmetrically arranged vibration motors are fixedly installed on the surface of the connecting pipe, the bottom end of the connecting pipe is rotatably connected to the connection of the stirring beaker, the surface of the measuring pipe is provided with measuring grooves, the installation of the vibration motors ensures that the bait is fed evenly, the magnetic stirrer evenly stirs the bait and water, the stirring beaker itself has a conical structure, and the water is drained out along the pipe.

[0013] Preferably, one end of the water tank is fixedly connected to a clean water delivery hose, and one end of the clean water delivery hose is fixedly connected to a clean water injection pipe extending into the inlet and outlet of the mixing cup. A clean water valve is fixedly installed in the middle of the clean water delivery hose. The other end of the water tank is fixedly connected to a flushing pipe extending to the front end of the feed cylinder connecting valve. A flushing valve is fixedly installed in the middle of the flushing pipe. When the clean water valve is opened, the clean water in the water tank is delivered to the mixing beaker through the clean water delivery hose, the peristaltic pump rotates forward, the feed cylinder connecting valve opens, and the clean water in the water tank is delivered to the pipeline and the mixing beaker for flushing after the flushing valve is opened. This flushes away the food residue in the pipeline and beaker after feeding. Filling the pipeline prevents air bubbles from entering the feeding main pipe. If there are air bubbles, it will lead to a reduction in the amount of food fed in some aquariums, or even prevent feeding altogether.

[0014] Preferably, each of the fish tanks is equipped with a feeding pipe at its top. A feeding valve is fixedly installed in the middle of the feeding pipe, and a system end valve is fixedly installed at one end of the feeding pipe. A compressed air injection pipe is fixedly connected to one side of the feeding pipe, and an air valve is fixedly installed in the middle of the compressed air injection pipe. One end of each of the feed delivery hoses is fixedly connected to the end of the feeding pipe directly opposite it. Compressed gas is injected through the compressed air injection pipe. Compressed air is injected after the air valve is opened. This step of injecting compressed air is done after rinsing to dry the rinsed pipes and prevent bacterial growth.

[0015] Preferably, the surface of the control box is hinged with two sealed doors that communicate with the motor housing and the feed chamber, respectively.

[0016] Preferably, the fish rack is fixedly installed with several solenoid valve plates located above the supporting crossbeam. Several indicator lights corresponding to the fish tanks are fixedly installed on the surface of the solenoid valve plates. When the corresponding fish tank is being fed, the corresponding indicator light will light up to remind the person that the fish tank is being fed.

[0017] Preferably, shock-absorbing feet are fixedly installed at the four corners of the bottom of the fish rack. The shock-absorbing feet reduce the vibration and impact during the operation of the fish rack and improve the stability of the fish rack itself.

[0019] 1. This system can feed fish precisely at set times and in measured quantities, saving manual labor and reducing the difficulty of feeding them;

[0020] 2. The system automatically feeds the zebrafish into the mixing beaker, while a peristaltic pump simultaneously injects water into the beaker. A magnetic stirrer at the bottom of the beaker mixes the feed and water evenly. The feed is then delivered to the fish tank via the peristaltic pump, with the amount of feed matching the number of zebrafish to ensure that overfeeding is not carried out.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-7 This utility model provides a novel intelligent fish feeding system, including a fish rack 1. Several supporting crossbeams 2 are fixedly installed inside the fish rack 1. Several fish tanks 4 are fixedly installed at the top of each supporting crossbeam 2. A water tank 3 is fixedly installed at the bottom of the inner wall of the fish rack 1. An operation box 8 is fixedly installed on one side of the fish rack 1. An operation panel 9 is fixedly installed at the top of the front of the operation box 8. A partition 13 is fixedly installed inside the operation box 8. The operation box 8 is divided from top to bottom into a motor chamber 14 and a feeding chamber 15 by the partition 13. A feeding assembly is fixedly installed inside the feeding chamber 15. 16. The feeding assembly 16 includes a stirring beaker 1606 and a peristaltic pump 1601. The inlet of the peristaltic pump 1601 is fixedly connected to a stirring beaker water injection hose 1602. A material cylinder connecting valve 1603 is fixedly installed in the middle of the stirring beaker water injection hose 1602. The end of the stirring beaker water injection hose 1602 away from the peristaltic pump 1601 is fixedly connected to a stirring beaker inlet / outlet 1609 opened on the surface of the stirring beaker 1606. The outlet of the peristaltic pump 1601 is fixedly connected to a feed conveying hose 1605. A magnetic stirrer 1604 is fixedly installed at the bottom of the stirring beaker 1606.

[0031] The bottom end of the magnetic stirrer 1604 is fixedly connected to the feeding chamber 15. The top end of the stirring beaker 1606 is fixedly connected to the connecting pipe 1607. Two symmetrically arranged vibration motors 1608 are fixedly installed on the surface of the connecting pipe 1607. The bottom end of the connecting pipe 1607 is rotatably connected to the connection between the stirring beaker 1606 and the bottom end of the connecting pipe 1607. The surface of the measuring pipe 1611 is provided with measuring grooves 1610. The installation of the vibration motors 1608 ensures that the bait is fed evenly. The magnetic stirrer 1604 evenly stirs the bait and water. The stirring beaker 1606 itself has a conical structure. The water is drained and discharged along the pipe. The measuring pipe 1611 is a central shaft. There are two semi-circular grooves at the top and bottom, which are measuring grooves 1610, used to measure the bait. The bait is sent to the stirring beaker 1606 below by rotation.

[0032] One end of the water tank 3 is fixedly connected to a clean water delivery hose 11, and one end of the clean water delivery hose 11 is fixedly connected to a clean water injection pipe 17 extending into the inlet / outlet 1609 of the mixing cup. A clean water valve 12 is fixedly installed in the middle of the clean water delivery hose 11. The other end of the water tank 3 is fixedly connected to a flushing pipe 23 extending to the front end of the feed cylinder connecting valve 1603. A flushing valve 24 is fixedly installed in the middle of the flushing pipe 23. After the clean water valve 12 is opened, the clean water in the water tank 3 is delivered to the mixing beaker 1606 through the clean water delivery hose 11, the peristaltic pump 1601 rotates forward, the feed cylinder connecting valve 1603 is opened, and the clean water is delivered to the mixing beaker 1606. After the flushing valve 24 is opened, the clean water in the water tank 3 is delivered to the mixing beaker 1606 through the flushing pipe 23 for flushing. After feeding, the food residue in the pipe and beaker is rinsed clean. The pipe is filled to avoid air bubbles in the main feeding pipe. If there are air bubbles, it will lead to a reduction in the amount of food in some fish tanks, or even no food at all.

[0033] Each of the fish tanks 4 is equipped with a feeding pipe 22 at its top. A feeding valve 20 is fixedly installed in the middle of the feeding pipe 22. A system end valve 21 is fixedly installed at one end of the feeding pipe 22. A compressed air injection pipe 18 is fixedly connected to one side of the feeding pipe 22. An air valve 19 is fixedly installed in the middle of the compressed air injection pipe 18. One end of the bait delivery hose 1605 is fixedly connected to the end of the feeding pipe 22 directly opposite to it. Compressed gas is injected through the compressed air injection pipe 18. Compressed air is injected after the air valve 19 is opened in order to dry the flushed pipes and prevent the growth of bacteria.

[0034] The surface of the control box 8 is hinged with two sealed doors 10, which communicate with the motor housing 14 and the feed chamber 15 respectively.

[0035] Several solenoid valve plates 6 are fixedly installed on the fish rack 1 above the support crossbeam 2. Several indicator lights 7 corresponding to the fish tank 4 are fixedly installed on the surface of the solenoid valve plates 6. When the corresponding fish tank 4 is being fed, the corresponding indicator light 7 lights up to remind the person that the fish tank 4 is being fed.

[0036] The four corners at the bottom of the fish rack 1 are all fixedly equipped with shock-absorbing feet 5. The shock-absorbing feet 5 reduce the vibration and impact of the fish rack 1 during operation and improve the stability of the fish rack 1 itself.

[0037] In this embodiment, the system automatically calculates the total amount of feed needed for each tank based on the user-preset feeding amount per fish, such as 5 mg / fish / meal. This ensures that each zebrafish receives just the right amount of nutrition, avoiding feed waste and water pollution caused by overfeeding. It operates fully automatically, saving time and effort. The system allows for flexible setting of daily feeding times and frequencies, and will strictly follow the plan to automatically execute the entire feeding process without the need for dedicated personnel, greatly liberating the productivity of researchers. It offers convenient management and intuitive control, supporting intuitive settings on a local touchscreen and remote monitoring and control via a mobile app. Supporting WIFI / 4G, it allows for management of feeding tasks anytime, anywhere. The system features seamless intelligent linkage between the water circulation and purification systems. The circulation pump automatically pauses when feeding begins to prevent feed loss. After feeding, the circulation pump automatically restarts and the pipeline self-cleaning function is activated to eliminate residue and ensure water purity and system hygiene. It also features efficient homogenization and delivery. The system intelligently completes feed weighing, water injection, and magnetic stirring homogenization. The peristaltic pump 1601 precisely delivers the uniform feed suspension to each designated fish tank 4, ensuring that every fish receives food. It boasts powerful scalability, allowing for large-scale operation. A single control system efficiently manages multiple fish racks 1, meeting the feeding needs of a large number of fish tanks 4 in large laboratories. It is suitable for large-scale zebrafish research. The installation of the vibration motor 1608 ensures uniform feed distribution. The magnetic stirrer 1604 evenly mixes the feed and water. The stirring beaker 1606 has a conical structure, draining water through a pipe. The metering pipe 1611 serves as a central shaft, with two semi-circular grooves at the top and bottom for metering feed. Rotation delivers the feed to the stirring beaker 1606 below. When a corresponding fish tank 4 is being fed, the corresponding indicator light 7 illuminates, reminding personnel that the fish tank 4 is being fed.

[0038] The specific process of this system is as follows:

[0039] 1. Prepare the bait:

[0040] Open the water valve 12 and the feed cylinder connection valve 1603, and the peristaltic pump 1601 will run in the forward direction. According to the preset feed mixing ratio, the water in the water tank 3 will be delivered to the mixing beaker 1606 through the water delivery hose 11 and the mixing cup water injection hose 1602, providing the required amount of water for feed mixing. At the same time, the vibration motor 1608 on the surface of the connecting pipe 1607 will start, and work with the metering groove 1610 of the metering pipe 1611 to complete the precise feeding. The magnetic stirrer 1604 will work synchronously to mix the feed and water evenly to form a feed suspension.

[0041] 2. Fill the supervisor's account:

[0042] Open the feed cylinder connecting valve 1603, feed valve 20 and system end valve 21, and switch the peristaltic pump 1601 to reverse operation. The feed suspension prepared in the stirring beaker 1606 is transported to the discharge pipe 22 through the feed conveying hose 1605. Fill the main pipeline composed of the feed conveying hose 1605 and the discharge pipe 22 according to the set amount to ensure that there are no air bubbles left in the pipeline and avoid the deviation in feeding amount caused by air bubbles during subsequent feeding.

[0043] 3. Feeding the fish:

[0044] With the feed cylinder connecting valve 1603 and the feed valve 20 open, open the valve corresponding to the target fish tank 4. The peristaltic pump 1601 continues to run in reverse, precisely delivering the feed suspension in the main pipeline to the corresponding fish tank 4 through the feed pipe 22. The feeding amount is preset and matched according to the number of zebra fish in the fish tank, achieving quantitative feeding. At this time, the indicator light 7 corresponding to the fish tank lights up, indicating that feeding is in progress.

[0045] 4. Clean the branch pipes:

[0046] After feeding is completed, close the feed cylinder connection valve 1603, open the flushing valve 24, the feed valve 20 and the valves corresponding to the target fish tank 4, the peristaltic pump 1601 runs in reverse, and the clean water in the water tank 3 enters the pipeline through the flushing pipe 23, flushing the feed conveying hose 1605, the feed pipe 22 and other conveying pipelines according to the set capacity, removing residual feed, and preventing pipeline blockage or deterioration and contamination.

[0047] 5. Branch air blowing:

[0048] Close the flushing valve 24, open the air valve 19 and the valve corresponding to the target fish tank 4, and compressed air enters the discharge pipe 22 through the compressed air injection pipe 18 to blow dry the flushed branch pipe, so as to avoid residual moisture in the pipe and the growth of bacteria, and ensure the hygiene of the system.

[0049] The feed used in this invention is a feed solution, not feed powder. The core function of the stirring beaker 1606 and the magnetic stirrer 1604 is to uniformly stir the feed solution: by mixing clean water (i.e., aquaculture water) with feed in a preset ratio, the magnetic stirrer 1604 drives the stirring components to fully stir the mixed feed solution, ensuring that the feed particles are uniformly suspended in the solution, avoiding uneven feeding caused by feed sedimentation, and laying the foundation for subsequent precise delivery.

[0050] During system operation, the "fill the main pipe" step plays a crucial role: opening the feed cylinder connecting valve 1603, the feed valve 20, and the system end valve 21 causes the peristaltic pump 1601 to reverse and transport the feed solution to the discharge pipe 22, ensuring that the entire main pipe is completely filled with the feed solution. This operation effectively eliminates air bubbles in the pipe. If air bubbles are present in the pipe, they can cause flow fluctuations during the feed solution delivery process, leading to reduced feeding or even no feeding in some aquariums 4. Filling the main pipe ensures that the feed solution supply to each aquarium 4 is precise and controllable.

[0051] The rinsing step after feeding is specifically designed to clean up residual feed: close the feed cylinder connecting valve 1603, open the rinsing valve 24, the feed valve 20 and the valve corresponding to the target fish tank 4, and the clean water in the water tank 3 enters the pipeline through the rinsing pipe 23. Driven by the peristaltic pump 1601, the feed delivery hose 1605, the feed pipe 22 and the stirring beaker 1606 are rinsed to thoroughly remove the feed residue remaining on the inner wall of the pipeline and in the container, preventing the residue from deteriorating and contaminating the pipeline or affecting the purity of the feed for the next feeding.

[0052] After rinsing, proceed to the branch pipe air blowing step: Close the rinsing valve 24, open the air valve 19 and the valve corresponding to the target aquarium 4, and compressed air enters the feed pipe 22 and related branch pipes through the compressed air injection pipe 18. The airflow thoroughly dries the residual moisture adhering to the inner wall of the pipes. This prevents bacteria from growing in the humid environment inside the pipes, ensures the hygiene of the system, reduces the risk of water pollution caused by bacterial growth, and ensures the safety of the zebrafish farming environment.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
