Description

Technical Field

[0001] The present invention relates to the technical field of fish farming, and particularly to a precise feeding system for fish farming with multi-modal fusion. Background Art

[0002] In traditional fish farming, there are many problems with the way of feeding fish food. In many farming scenarios, manual feeding is still used. This method not only consumes a large amount of manpower and time, but also it is difficult to ensure the precision and uniformity of feeding. Manual feeding often can only rely on the experience of farmers to judge the feeding amount and feeding position, and cannot make timely and accurate adjustments according to the actual needs of the fish population and the growth environment.

[0003] Some farms have already adopted some simple mechanical feeding devices, but these devices have single functions and lack a comprehensive perception of the growth environment and state of the fish population. They usually can only feed according to preset time and quantity, and cannot dynamically adjust the feeding strategy according to parameters such as water temperature, dissolved oxygen, pH value of the water body and real-time information such as the activity of the fish population and feeding state.

[0004] In addition, the existing feeding devices also have deficiencies in terms of feeding range and uniformity. The feeding range of some devices is limited, resulting in uneven distribution of fish food. In some areas, the fish population overfeeds, while in other areas, the fish population underfeeds. This not only affects the growth and development of the fish population, but also may cause waste of feed and pollution of water quality.

[0005] With the continuous expansion of the scale of fish farming and the increasing requirements for farming efficiency and quality, the traditional feeding methods and simple mechanical feeding devices are difficult to meet the needs of modern farming. Therefore, it is of great practical significance to develop a precise feeding system for fish farming with multi-modal fusion that can achieve precise feeding and improve feeding efficiency and uniformity. Summary of the Invention

[0006] In order to solve the problems mentioned in the above background art, the present invention provides a precise feeding system for fish farming with multi-modal fusion.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A precise feeding system for fish farming with multi-modal fusion, including an aquaculture environment monitoring unit, a real-time meteorological monitoring unit, a water quality monitoring unit, a fish information storage unit, an automatic feeding control unit for fish farming, and a precise feeding execution unit. The precise feeding execution unit includes a feeding actuator, and the feeding actuator includes a fish food storage container. The fish food storage container is installed on a remote control boat. A lifting drive box is fixed on one side of the fish food storage container. The lifting drive box drives the lifting cross bar to move up and down. A lifting cylinder and a rotary drive rod are respectively fixed on the lifting cross bar. The outer top end of the lifting cylinder is rotatably installed with a feeding container. A plurality of feeding openings are arranged near the bottom end of the side edge of the feeding container.

[0009] The bottom end of the feeding container is fixed with a long gear. The inside of the long gear is hollow. The lifting cylinder movably penetrates through the long gear. The top end of the fish food storage container is rotatably installed with a short gear through a bracket. A guiding ring is arranged on the short gear. The rotary drive rod penetrates through the guiding ring, and the two are in threaded cooperation. The long gear meshes with the short gear. The diameter of the short gear is larger than that of the long gear.

[0010] Preferably, a lifting screw is installed in the fish food storage container. The top end of the lifting screw extends into the lifting cylinder, and the lifting screw is driven to rotate by a first rotating motor.

[0011] Preferably, a spiral groove is arranged on the outer part of the rotary drive rod. A limiting column is fixed on the inner wall of the guiding ring. The limiting column extends into the spiral groove.

[0012] Preferably, the density of the spiral groove gradually increases from top to bottom. A blocking baffle is fixed at the top end of the rotary drive rod.

[0013] Preferably, a plurality of arc-shaped scraping plates are fixed at the position near the bottom end on the outer side of the lifting screw. The arc-shaped scraping plates match the inner wall of the bottom end of the fish food storage container.

[0014] Preferably, a threaded rod and a guiding rod are respectively installed inside the lifting drive box. The threaded rod is driven to rotate by a second rotating motor.

[0015] Preferably, a threaded sleeve and a guiding sleeve are respectively fixed on the lifting cross bar. The threaded sleeve is threadedly installed on the outer part of the threaded rod. The guiding sleeve is movably installed on the outer part of the guiding rod.

[0016] Preferably, a guiding convex platform is arranged inside the feeding container, and a plurality of partition baffles are fixed at the top end of the guiding convex platform.

[0017] Preferably, the partition baffles are arc-shaped, and the bending direction thereof is opposite to the rotating direction when the feeding container feeds. The gap between adjacent partition baffles corresponds to the position of the feeding opening.

[0018] Preferably, a blocking baffle is provided on the outside of the material spreading container at a position corresponding to the material spreading opening, and a counterweight ball is connected to the bottom end of the blocking baffle via a soft rope.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Precision and efficient feeding: The multimodal sensing unit collects data on water parameters, fish activity, weather, and other aspects. The information fusion processor unit conducts in-depth analysis of this data. The reasoning and decision-making unit formulates an adaptive feeding strategy based on the AI reasoning model. The autonomous optimization unit continuously updates the model parameters based on the feedback of feeding effects. Finally, the precision feeding execution unit automatically and accurately feeds the fish, improving feeding efficiency and accuracy.

[0021] 2. Expanding the feeding range and improving uniformity: The lifting drive box raises and lowers the feed container, while the rotating drive rod, threaded with the guide ring, rotates the container. As the container rises, it rotates rapidly, distributing the food through the opening. The constant change in height of the container increases the feeding range and improves feeding uniformity. Furthermore, the density of the spiral grooves on the rotating drive rod increases from top to bottom, resulting in faster rotation as the container rises, further improving food distribution uniformity.

[0022] 3. Automatic Feeding and Improved Fluidity: A lifting screw inside the fish food storage container, driven by a first rotary motor, automatically lifts the fish food into the feeding container for automatic feeding. A curved scraper at the bottom of the lifting screw stirs the fish food during feeding, improving fluidity and feeding efficiency.

[0023] 4. Automatic opening and closing of the feeding opening: The sealing baffle on the outside of the feeding container cooperates with the counterweight ball to block the feeding opening when the feeding container is stationary, and use centrifugal force to open the feeding opening when it rotates, realizing automatic opening and closing according to the working status, preventing fish food from being spilled when not in working state.

Detailed implementation method

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] Reference Figures 1-11 , a precise feeding system for fish farming with multi-modal fusion, includes a breeding environment monitoring unit, a real-time meteorological monitoring unit, a water quality monitoring unit, a fish information storage unit, an automatic feeding control unit for fish farming, and a precise feeding execution unit. The precise feeding execution unit includes a feeding actuator, and the feeding actuator includes a fish food storage container 1. The fish food storage container 1 is installed on a remote control boat. A lifting drive box 2 is fixed on one side of the fish food storage container 1. The lifting drive box 2 drives the lifting cross bar 201 to move up and down. A lifting cylinder 202 and a rotary drive rod 203 are respectively fixed on the lifting cross bar 201. A feeding container 4 is rotatably installed at the outer top of the lifting cylinder 202. A plurality of feeding openings 404 are provided at a position near the bottom of the side edge of the feeding container 4;

[0040] The breeding environment monitoring unit uses cameras distributed in the fish pond to collect image data in real time, establishes an image database of the breeding site, and realizes the classification and measurement of water surface pollutants, algae, and fish behavior through the YOLO visual target detection algorithm and self-updating training iteration;

[0041] The real-time meteorological monitoring unit docks multiple types of meteorological sensors through the RS485 communication interface to complete the measurement of parameters such as light, wind speed, wind direction, and rainfall, providing parameter basis for the AI decision-making large model;

[0042] The water quality monitoring unit docks multiple types of water quality sensors through the RS485 communication interface to complete the measurement of parameters such as dissolved oxygen, water temperature, PH value, ammonia nitrogen, and turbidity, providing parameter basis for the AI decision-making large model;

[0043] The fish information storage unit establishes a knowledge base of fish information, fish habit information, and historical feeding experience data in the background server to participate in the decision-making of the AI feeding model;

[0044] The automatic feeding control unit for fish farming takes the AI computing power chip as the main control core. Through the local deployment of the mainstream lightweight large model, it can fuse, analyze, and reason the sensor data, fish library information, and historical experience data in real time, so as to control the precise feeding execution unit to feed;

[0045] The system includes multiple video monitoring cameras for real-time viewing and intermittent image acquisition to automatically identify the breeding environment information. The system also includes a 4G or 5G communication module for data sharing and interaction with the digital fishery service platform, facilitating users to directly manage the system. And the system is powered by a photovoltaic power supply system.

[0046] A long gear 401 is fixed to the bottom end of the feeding container 4. The inside of the long gear 401 is hollow. The lifting cylinder 202 movably penetrates through the long gear 401. The top end of the fish food storage container 1 is rotatably installed with a short gear 102 through a bracket 101. A guiding ring 103 is provided on the short gear 102. The rotating drive rod 203 penetrates through the guiding ring 103, and the two are in threaded cooperation. The long gear 401 meshes with the short gear 102. The diameter of the short gear 102 is larger than that of the long gear 401.

[0047] By driving the lifting cross bar 201 to move up and down through the lifting drive box 2, the lifting cylinder 202 and the rotating drive rod 203 can be driven to move up and down synchronously, and then the feeding container 4 can be driven to move up and down. Due to the threaded cooperation between the rotating drive rod 203 and the guiding ring 103, when the rotating drive rod 203 passes through the guiding ring 103, it can drive the guiding ring 103 to rotate, and then drive the short gear 102 to rotate. Since the long gear 401 is relatively long, during the process of the long gear 401 following the feeding container 4 to move up and down, it can maintain the meshing state with the short gear 102, and can drive the long gear 401 to rotate through the rotation of the short gear 102. And because the diameter of the short gear 102 is larger than that of the long gear 401, the feeding container 4 can be driven to rotate rapidly while rising, so as to sprinkle the fish food stored in the feeding container 4 from the feeding opening 404, achieving the effect of automatically feeding fish food. And because the height of the feeding container 4 will change continuously, when the initial velocity of the fish food being sprinkled is constant, the higher the height, the farther the fish food will be sprinkled. The feeding range of the fish food can be increased by changing the height of the feeding container 4, and the feeding uniformity can be improved.

[0048] Embodiment 2

[0049] Refer to Figures 1-10 This embodiment is different from Embodiment 1 in that a lifting screw 104 is installed in the fish food storage container 1. The top end of the lifting screw 104 extends into the lifting cylinder 202, and the lifting screw 104 is driven to rotate by a first rotating motor 105.

[0050] The first rotating motor 105 can drive the lifting screw 104 to rotate, so as to lift the fish food in the fish food storage container 1 to the feeding container 4 through the lifting cylinder 202, achieving the purpose of automatic feeding. When feeding, the feeding container 4 is in the lowest state (as Figure 4 shown), and at this time, the top end of the lifting screw 104 extends outside the top end of the lifting cylinder 202 (as Figure 5 shown).

[0051] Embodiment 3

[0052] Refer to Figures 1-10, The difference between this embodiment and Embodiment 1 is that a spiral groove 2032 is formed on the outer surface of the rotary drive rod 203, and a limiting post 1031 is fixed on the inner wall of the guide ring 103. The limiting post 1031 extends into the spiral groove 2032, and the density of the spiral groove 2032 gradually increases from top to bottom;

[0053] Since the limiting post 1031 is stuck in the spiral groove 2032, the guide ring 103 can be driven to rotate along the spiral groove 2032, converting the relative vertical movement between the guide ring 103 and the rotary drive rod 203 into the rotation of the guide ring 103. And because the density of the spiral groove 2032 gradually increases from top to bottom, the higher the rising height of the guide ring 103, the greater the rotation speed, so that the initial velocity when the fish food is spilled can be further increased, and the uniformity of the fish food spill can be further improved;

[0054] A blocking baffle 2031 is fixed at the top end of the rotary drive rod 203. The blocking baffle 2031 can block the falling fish food to prevent the fish food from falling into the spiral groove 2032 and causing a jamming phenomenon.

[0055] Wherein, a plurality of arc-shaped scraping plates 1041 are fixed at the outer side near the bottom end of the lifting screw rod 104. The arc-shaped scraping plates 1041 match the inner wall of the bottom end of the fish food storage container 1. By rotating the arc-shaped scraping plates 1041, the fish food can be continuously stirred during feeding, improving the fluidity of the fish food and the feeding efficiency.

[0056] Wherein, a threaded rod 205 and a guide rod 204 are respectively installed inside the lifting drive box 2. The threaded rod 205 is driven to rotate by a second rotary motor 206. Threaded sleeves 2011 and guide sleeves 2012 are respectively fixed on the lifting cross bar 201. The threaded sleeve 2011 is threadedly installed outside the threaded rod 205, and the guide sleeve 2012 is movably installed outside the guide rod 204;

[0057] Driving the threaded rod 205 to rotate by the second rotary motor 206 can drive the lifting cross bar 201 to move up and down.

[0058] Wherein, a guide convex platform 402 is provided inside the feeding container 4, and a plurality of partition baffles 403 are fixed at the top end of the guide convex platform 402. The partition baffles 403 are arc-shaped, and the bending direction thereof is opposite to the rotation direction of the feeding container 4 when feeding, and the gap between adjacent partition baffles 403 corresponds to the position of the feeding opening 404. The partition baffles 403 can, through the guiding action of the inclined surface, enable the fish food under the centrifugal force to be guided along the partition baffles 403 to move to the position of the feeding opening 404, so as to be smoothly spilled.

[0059] Among them, a blocking baffle 405 is connected to the corresponding position of the material spreading opening 404 on the outside of the material spreading container 4, and the bottom end of the blocking baffle 405 is connected to a counterweight ball 4051 through a soft rope. When the material spreading container 4 is in the prohibited state, the gravity of the counterweight ball 4051 will pull the blocking baffle 405 to a vertical state, thereby blocking the material spreading opening 404. When the material spreading container 4 rotates, the release force will throw the counterweight ball 4051 up, thereby pulling the blocking baffle 405 to a horizontal state, thereby opening the material spreading opening 404, thereby achieving the purpose of automatically opening and closing the material spreading opening 404 according to the working state.
