Description

Technical Field

[0001] This invention belongs to the field of multi-trophic level polyculture ponds, specifically relating to a multi-trophic level polyculture pond for golden pomfret, tiger prawn, and mud crab. Background Technology

[0002] Multitrophic level polyculture ponds are an aquaculture model that mimics natural ecosystems. By combining organisms from different trophic levels (such as fish, shrimp, crabs, shellfish, and algae), they achieve material recycling, reduce pollution, and improve overall efficiency. Currently, they are widely used in marine aquaculture. However, when farming golden pomfret, tiger prawns, and mud crabs, while polyculture ponds can be used to cultivate these three species together, the different growth rates of the juvenile fish, shrimp, and crabs can lead to cannibalism in the middle stages of cultivation, causing mortality. Furthermore, oxygenation can only be provided to the surface layer, resulting in reduced oxygen levels in the lower water layers, which negatively impacts the growth of the cultured organisms. Therefore, improvements to existing technologies are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-trophic level polyculture pond for golden pomfret, tiger prawn, and mud crab, which solves the problems of predation between existing cultured organisms and the inconvenience of oxygenation in the water.

[0004] To achieve the above objectives, the present invention provides a multi-trophic-level polyculture pond for golden pomfret, tiger prawn, and mud crab, comprising a pond body, wherein a lower isolation net is slidably connected to the lower part of the inner wall of the pond body, an upper isolation net is slidably connected to the upper part of the inner wall of the pond body, a plurality of evenly distributed support legs are fixedly connected to the lower end of the upper isolation net, a support rod is fixedly connected to the upper end of the upper isolation net, a disassembly and assembly mechanism is provided on the pond body, an air supply pipe is fixedly installed at the right end of the pond body, an exhaust hood is fixedly connected to the middle of the inner bottom surface of the pond body, an aerator is mounted on the upper end of the exhaust hood via a bearing, a plurality of evenly distributed one-way air nozzles are fixedly installed on the upper end of the aerator, and a paddle is fixedly connected to the outer side of the aerator located inside the exhaust hood;

[0005] The disassembly and assembly mechanism includes a connecting seat, the upper end of the support rod is fixedly connected to the connecting seat, a fixing frame is fixedly connected to the outer side of the pool body, an inclined frame is slidably connected to the outer side of the fixing frame, a spring is provided on the outer side of the fixing frame, a pull ring is fixedly connected to the upper part of the outer side of the inclined frame, and multiple pairs of evenly distributed positioning rods are fixedly connected to the upper end of the pool body.

[0006] The principle of this invention is as follows: During use, the pond can be divided into three layers using lower and upper isolation nets. Then, based on the living habits of fish, shrimp, and crabs, stratified farming can be carried out, effectively avoiding predation during the farming process. When oxygenation is needed, gas is transported through the air supply pipe. When the airflow enters the interior of the exhaust hood from the air supply pipe, the airflow blows the paddles to rotate, and the paddles drive the aerator to rotate. Simultaneously, the airflow is sprayed into the water through one-way nozzles above the aerator. Thus, oxygenation is achieved from the bottom of the water through the rotation of the aerator and the sprayed airflow, thereby... This method ensures more even oxygenation within the pond. When harvesting the aquatic organisms, the upper layer is harvested first. Then, the pull ring is pulled, causing the inclined frame to move and compressing the spring. When the inclined frame disengages from the connecting seat, the limiting position on the connecting seat is released. Then, the support rod is pulled, causing the upper isolation net to move. Once the upper isolation net is detached from the pond, the middle layer of aquatic organisms can be harvested. After removing the lower isolation net, the bottom layer of aquatic organisms can be harvested. This method avoids cannibalism among aquatic organisms and makes harvesting easier by distinguishing them.

[0007] The beneficial effects of this invention are as follows: By adding an upper isolation net, a lower isolation net, and a disassembly and assembly mechanism to the inside of the pool, the pool can be divided into three layers for aquaculture during use. This allows for the separation of individual species, effectively preventing predation between aquatic organisms. Furthermore, the bottom of the pool can be oxygenated through the air supply pipe and rotating aerator during aquaculture, resulting in more uniform oxygenation of the water inside the pool.

[0008] Furthermore, a baffle is fixedly connected to the outer side of the support leg. The baffle slides in contact with the lower isolation net, the support leg slides in contact with the lower isolation net, and the support leg slides in contact with the pool body. The baffle can squeeze and limit the lower isolation net.

[0009] Furthermore, a sealing ring is fixedly connected to the upper end of the exhaust hood, and the sealing ring is rotatably connected to the oxygenation frame. The sealing ring can seal the connection between the exhaust hood and the oxygenation frame.

[0010] Furthermore, multiple evenly distributed mounting brackets are fixedly connected to the vertical surface of the right end of the pool body. The mounting brackets are fixedly connected to the gas supply pipe, and the mounting brackets can fix the gas supply pipe.

[0011] Furthermore, the connecting seat is in slidable contact with the pool body, the connecting seat is slidably connected to the positioning rod, the inclined frame is in slidable contact with the connecting seat, and the positioning rod can position the connecting seat.

[0012] Furthermore, one end of the spring is fixedly connected to the inclined plane frame, and the other end of the spring is fixedly connected to the fixed frame. The spring can automatically reset the inclined plane frame through its elastic force.

[0013] Furthermore, the mesh diameter of the lower isolation net is smaller than that of the upper isolation net.

[0014] Furthermore, the pool is equipped with a water quality sensor, a camera, and a control module; an automatic feed dispensing device is installed on the outside of the pool; and a gas flow control valve is installed on the gas supply pipe, wherein:

[0015] The water quality sensors are distributed in the upper, middle and bottom layers of the pool to detect dissolved oxygen, pH value and ammonia nitrogen content;

[0016] The camera is installed on the top or inside of the pool to capture images of the activities of the organisms in the upper layer.

[0017] The control module has a built-in artificial intelligence algorithm. Its signal input terminal is electrically connected to the water quality sensor and the camera, and its signal output terminal is electrically connected to the automatic feed feeding device and the gas flow control valve of the gas pipeline.

[0018] The control module is configured to: analyze the feeding status based on the images of upper-layer organisms collected by the camera; when it is determined that feeding is required, control the automatic feeding device to evenly distribute feed to the upper layer of the pond; at the same time, based on the water quality sensor data of the middle and bottom layers and the images of biological activity, adjust the gas flow rate of the air supply pipe, and control the water flow rate by the rotation speed of the aerator, so as to promote the sinking of upper-layer excrement and residual feed to the middle and bottom layers for feeding by tiger prawns and mud crabs.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a multi-trophic-level polyculture pond for golden pomfret, tiger prawn, and mud crab, including a pond body 1. A lower isolation net 2 is slidably connected to the lower part of the inner wall of the pond body 1, and an upper isolation net 3 is slidably connected to the upper part of the inner wall of the pond body 1. Multiple evenly distributed support legs 4 are fixedly connected to the lower end of the upper isolation net 3, and a support rod 7 is fixedly connected to the upper end of the upper isolation net 3.

Multiple evenly distributed one-way air nozzles 12 are fixedly installed on the upper end of the oxygenation frame 11. A paddle blade 14 is fixedly connected to the outer side of the oxygenation frame 11 inside the exhaust hood 10.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a baffle 5 is fixedly connected to the outer side of the support leg 4. The baffle 5 slides in contact with the lower isolation net 2, the support leg 4 slides in contact with the lower isolation net 2, and the support leg 4 slides in contact with the pool body 1. The baffle 5 can squeeze and limit the lower isolation net 2. A sealing ring 13 is fixedly connected to the upper end of the exhaust hood 10. The sealing ring 13 is rotatably connected to the oxygenation frame 11. The sealing ring 13 can seal the connection between the exhaust hood 10 and the oxygenation frame 11. Multiple evenly distributed mounting frames 15 are fixedly connected to the vertical surface of the right end of the pool body 1. The mounting frames 15 are fixedly connected to the gas supply pipe 9. The mounting frames 15 can fix the gas supply pipe 9.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the disassembly and assembly mechanism 8 includes a connecting seat 81. The upper end of the support rod 7 is fixedly connected to the connecting seat 81. A fixing frame 82 is fixedly connected to the outside of the pool body 1. An inclined frame 83 is slidably connected to the outside of the fixing frame 82. A spring 84 is provided on the outside of the fixing frame 82. A pull ring 85 is fixedly connected to the upper part of the outside of the inclined frame 83. Multiple pairs of evenly distributed positioning rods 86 are fixedly connected to the upper end of the pool body 1. The inclined frame 83 can limit the connection seat 81. The connecting seat 81 is in sliding contact with the pool body 1. The connecting seat 81 is slidably connected to the positioning rods 86.

The spring 84 can automatically reset the inclined frame 83 through its elastic force. The mesh diameter of the lower isolation net 2 is smaller than the mesh diameter of the upper isolation net 3.

[0030] The specific implementation process of this invention is as follows: In use, the pond body 1 can be divided into three layers by the lower isolation net 2 and the upper isolation net 3. Then, according to the living habits of fish, shrimp and crabs, they can be cultured in layers, which can effectively avoid the problem of predation between them during the breeding process. When oxygenation is needed, the air supply pipe 9 transports gas. When the airflow enters the interior of the exhaust hood 10 from the air supply pipe 9, the airflow blows the paddle 14 to rotate. The paddle 14 drives the aerator 11 to rotate. At the same time, the airflow is sprayed into the interior of the water body through the one-way air nozzle 12 above the aerator 11. Thus, oxygenation can be achieved from the bottom of the water body through the rotation of the aerator 11 and the sprayed airflow. The oxygenation inside the pond 1 is more uniform. When it is necessary to harvest the aquatic organisms, the aquatic organisms in the upper layer of the pond 1 are harvested first. Then, the pull ring 85 is pulled, which moves the inclined frame 83 and compresses the spring 84. When the inclined frame 83 disengages from the connecting seat 81, the limiting position on the connecting seat 81 is released. Then, the support rod 7 is pulled, which moves the upper isolation net 3. When the upper isolation net 3 disengages from the pond 1, the aquatic organisms in the middle layer can be harvested. Then, the lower isolation net 2 is removed, and the aquatic organisms at the bottom can be harvested. This can avoid the aquatic organisms from preying on each other and make it easier to distinguish and harvest them.

[0031] This invention adds an upper isolation net 3, a lower isolation net 2, and a disassembly and assembly mechanism 8 to the inside of the pool body 1. During use, the pool body 1 can be divided into three layers for aquaculture through the upper and lower isolation nets, which can separate individual species and effectively prevent predation between aquatic organisms. Furthermore, during the aquaculture process, the bottom of the pool body 1 can be oxygenated through the bottom air supply pipe 9 and rotating aerator 11, which can make the oxygenation of the water inside the pool body 1 more uniform.

[0032] In another embodiment, to further improve the intelligent aquaculture level of the polyculture pond and achieve precise control and efficient resource utilization in the aquaculture process, a water quality sensor, camera and control module are added inside the pond 1, an automatic feed feeding device is installed on the outside of the pond 1, and a gas flow control valve is installed on the gas pipe 9. All components work together to complete the intelligent management of the entire aquaculture process.

[0033] Specifically, the water quality sensor uses a Y500 multi-parameter water quality sensor, with two sensors deployed in each water layer, distributed in the upper, middle, and bottom layers of pool 1, respectively, to detect dissolved oxygen, pH value, and ammonia nitrogen content; the camera uses an IPC-T12H high-definition network camera with a resolution of 1080P and a frame rate of 25fps, installed at the top center and inner middle of pool 1, with a lens angle of 120°, fixed by a bracket, to collect images of the activity of organisms in the upper layer;

[0034] The control module uses an STM32F407 microcontroller with a built-in YOLOv5-based artificial intelligence algorithm. It integrates a data acquisition module, an image processing module, and an instruction output module. Its signal input terminal is electrically connected to the water quality sensor and camera via an RS485 bus, and its signal output terminal is electrically connected to the automatic feed feeding device and the gas flow control valve of the gas supply pipe 9 via a relay. The automatic feed feeding device is an SF-100 automatic feeder with a feeding amount adjustment range of 0-5 kg / feed and a feeding radius of 3-5 m. It is installed on the upper outer side of the pool body 1, with the feeding port facing the upper center area of ​​the pool body 1. The gas flow control valve is a DN50 electric ball valve, which is connected in series with the gas supply pipe 9.

[0035] Water quality sensors are evenly distributed in the upper, middle, and bottom layers of the pond 1. Their core function is to detect the dissolved oxygen, pH value, and ammonia nitrogen content in the corresponding water layers in real time, providing data support for the control of the aquaculture environment. Cameras are fixedly installed on the top or inside of the pond 1, with the lens facing the upper aquaculture area of ​​the pond 1, continuously collecting images of the activities of upper-layer organisms such as golden pomfret, and accurately capturing key information such as feeding behavior and swimming status.

[0036] The control module has a built-in mature artificial intelligence algorithm. Its signal input end is stably electrically connected to the water quality sensor and camera through wires, and can receive monitoring data and image information from each detection component in real time. The signal output end is also electrically connected to the automatic feed feeding device and the gas flow control valve of the gas pipe 9 through wires, and has the ability to issue commands and regulate equipment.

[0037] In actual aquaculture, the control module intelligently analyzes the images of upper-layer organisms captured by the camera, judging the feeding status by identifying characteristics such as the aggregation density and mouth opening frequency of the golden pomfret. When it is determined that there is insufficient feed in the water and the organisms are in a state of hunger, the control module immediately sends a feeding instruction to the automatic feeding device, controlling it to evenly distribute feed suitable for the golden pomfret to the upper layer of the pond, ensuring uniform feeding and avoiding feed waste.

[0038] Simultaneously, the control module receives dissolved oxygen, pH, and ammonia nitrogen data from water quality sensors at the upper, middle, and bottom layers of pond 1. Combined with images of biological activity at the middle and bottom layers captured by cameras, it comprehensively assesses the aquatic environment and the feeding needs of the organisms. When the dissolved oxygen level in a certain water layer falls below a set threshold, or the ammonia nitrogen level exceeds the standard, the control module adjusts the gas flow control valve of the air supply pipe 9, changing the gas flow rate delivered from the air supply pipe 9 to the exhaust hood 10. This change in gas flow rate directly affects the rotation speed of the paddle 14, which in turn changes the rotation speed of the aerator 11, thereby controlling the water flow velocity within pond 1. A reasonable water flow velocity not only increases the dissolved oxygen level in each water layer through the airflow injected by the one-way nozzle 12, but also promotes the slow sinking of excrement and residual feed from the upper-layer golden pomfret to the middle and bottom layers, providing natural food for tiger prawns and mud crabs. This achieves resource utilization of aquaculture waste, reduces water pollution, and maintains the ecological balance within pond 1.

[0039] Furthermore, the control module can store and analyze historical monitoring data and control records, and continuously optimize control parameters such as feeding amount and gas flow rate through artificial intelligence algorithms to adapt to the growth needs of organisms at different breeding stages, further improving the survival rate and overall benefits. The addition of the above-mentioned intelligent components, together with the layered breeding structure of the upper isolation net 3 and the lower isolation net 2 and the uniform oxygenation structure of the aeration rack 11, forms a multi-dimensional breeding system of "layered isolation + precise oxygenation + intelligent control", which significantly improves the scientificity and convenience of polyculture of golden pomfret, tiger prawn and mud crab.
