Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a honeycomb-style automated aquaculture method. Background Technology

[0002] High-density aquaculture is difficult to conduct in large areas such as ponds because the range of aquatic environmental factors that need to be regulated is too vast, making uniform control challenging. Currently, high-density aquaculture is generally carried out only in small circular or square areas. High-density aquaculture requires high water quality, necessitating mechanical aeration and active water circulation, as well as timely waste removal; otherwise, poor water quality will lead to mass mortality of farmed organisms within a short period. A single water quality sensor can cost tens of thousands of yuan, and its lifespan is generally only 3-6 months due to algae growth and adhesion. The cost far exceeds the profit margin of aquaculture. Therefore, current high-density aquaculture generally adopts open-loop control, continuously aerating and circulating water, resulting in high energy consumption and high aquaculture costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a honeycomb-type automatic aquaculture method, which overcomes the shortcomings of existing methods that cannot be used for high-density aquaculture in large water bodies and the disadvantages of high cost and high energy consumption of high-density aquaculture sensors.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A honeycomb-based automated farming method includes the following steps:

[0006] 1) Fish fry stocking and feeding: The target output is 1-2 tons of fish products per honeycomb partition device. The stocking amount at the beginning of the year is calculated based on the annual net weight gain multiple of different fish species and sizes. Commercially available extruded feed is used as feed, and the feeding is carried out according to the habits of the fish.

[0007] 2) Water circulation: The water circulation system is running at all times to ensure that the water in the honeycomb breeding box is always in a circular flow state;

[0008] 3) When the mobile monitoring vessel is patrolling and detecting, it obtains its location through the power supply-wireless positioning and control module it carries. The integrated sensor collects environmental factor data of the honeycomb breeding box, transmits it to the Internet of Things platform through the WiFi module, and then transmits the data to the WeChat mini program for processing and display using the MQTT protocol. Based on the processing results, it sends instructions to other systems to improve the environment of the honeycomb breeding box.

[0009] 4) Solid waste collection and discharge: The sewage pump on the solid waste collection and discharge system is turned on for 3-5 minutes every day to discharge sewage, filter and collect solid waste and turn it into fertilizer; water-soluble waste such as ammonia nitrogen is self-purified by the water in the pond outside the honeycomb breeding box.

[0010] The honeycomb-style automated aquaculture system includes honeycomb breeding boxes, a solid waste collection and disposal system, a water circulation system, and a mobile monitoring vessel;

[0011] The honeycomb breeding box has a honeycomb structure, and there is a notch at the upper end of each side plate of the honeycomb breeding box. The movable floating door slides with the notch and can move up and down along the notch.

[0012] The solid waste collection and discharge system includes multiple sludge collection funnels. The upper end of each sludge collection funnel is connected to the chamber of the honeycomb breeding box in a one-to-one correspondence. The lower end of each sludge collection funnel is connected to the sewage discharge pipe and filtered through a movable grid. The other end of the sewage discharge pipe is connected to a sewage suction pump, which discharges the waste.

[0013] The water circulation system includes a main water pipe, the outlet of which is connected to multiple branch spray pipes, which are located in the chamber of the beehive breeding box and distributed from top to bottom; the inlet of the main water pipe is connected to a water supply pipe and a booster pump in sequence, and the booster pump introduces oxygen-enriched water.

[0014] The mobile monitoring vessel includes a hull, on which are installed a propeller, an integrated sensor, a power-wireless positioning and control module. The propeller drives the hull to move, and the second servo motor drives the propeller to deflect left and right to achieve hull steering. The integrated sensor is driven by the first servo motor to extend into the water or out of the water surface.

[0015] The integrated sensor is used to measure dissolved oxygen, ammonia nitrogen content, dissolved salt, pH value, water transparency, and temperature in water bodies.

[0016] The power-wireless positioning and control module is used to receive signals from the integrated sensor and transmit them wirelessly.

[0017] The honeycomb-style automated farming method provided by this invention has the following technical effects:

[0018] 1) By introducing a honeycomb structure, the honeycomb aquaculture box mimics the shape of a honeycomb, dividing a large water area into several smaller areas. The upper hexagonal prism section is used for fish rearing, utilizing a water circulation system for forced aeration and water circulation, avoiding the problem of inconvenient water flow control in large water areas. The lower hexagonal pyramid section can collect and discharge waste. This structure optimizes the problem of insufficient pond area utilization and lack of shared boundaries between cylindrical aquaculture boxes, which helps to improve the utilization rate of pond unit area, ensuring no unused space between rearing boxes. Furthermore, adjacent honeycomb aquaculture boxes can share partitions, greatly saving construction costs. At the same time, the perimeter of the regular hexagonal honeycomb aquaculture box is smaller than that of a quadrilateral aquaculture box of the same area, thus requiring less material. The fact that honeycomb aquaculture boxes can share adjacent partitions further reduces material input. The 120° interior angle of the regular hexagonal honeycomb aquaculture box avoids the 90° hydraulic dead angle of the quadrilateral, allowing circulating water to flow throughout and ensuring uniform water quality.

[0019] 2) By installing movable floating doors on the honeycomb breeding boxes, it is convenient for the mobile monitoring vessel to enter and exit. The introduced mobile monitoring vessel can cruise and monitor the water quality of each honeycomb breeding box for real-time control. Moreover, the mobile monitoring vessel avoids the expensive investment of arranging fixed detection devices in each chamber of each honeycomb breeding box, thus reducing detection costs. Using the location information and detection information of the mobile monitoring vessel, the water environment of specific honeycomb breeding boxes can be controlled in real time as needed, reducing energy consumption while ensuring water quality.

Detailed Implementation

[0027] like Figure 1 As shown, a honeycomb-type automated aquaculture system consists of a honeycomb breeding box 100, a solid waste collection and disposal system 200, a water circulation system 300, and a mobile monitoring vessel 400.

[0028] like Figure 2As shown, the honeycomb breeding box 100 has a honeycomb structure, composed of multiple hollow hexagonal prisms. Each hollow hexagonal prism has a side length of 2-3m, and its depth is determined according to the pond water level. The honeycomb breeding box 100 is about 0.1m above the water surface. Each side plate 3 of the honeycomb breeding box 100 has a notch at its top, and a movable floating door 1 is installed at the notch. The movable floating door 1 is H-shaped and has a relatively smooth surface. The grooves at both ends of the movable floating door 1 slide with the notch. The density of the movable floating door 1 is less than that of water, so it floats on the water surface when no external force is applied. The lower end of the movable floating door 1 is connected to the fishing net 2 at the front and back, and the two fishing nets 2 are attached to the inner and outer walls of the side plate 3.

[0029] When the mobile monitoring vessel 400 moves forward to the movable floating gate 1, the forward rocker arm 18 presses down on the movable floating gate 1, loosening the fishing net 2. The movable floating gate 1 then submerges in the water, allowing the mobile monitoring vessel 400 to pass smoothly through it. After the vessel has passed the movable floating gate 1, the pressure on the gate disappears, the movable floating gate 1 floats up naturally, and the fishing net 2 stretches and returns to its original state. The coordinated design of the movable floating gate 1 and the fishing net 2 not only allows the mobile monitoring vessel 400 to easily enter the honeycomb breeding box to complete the inspection, but also prevents the fish from escaping. Furthermore, it facilitates water exchange between the inner and outer surfaces of the honeycomb breeding box 100.

[0030] like Figure 3 As shown, the solid waste collection and disposal system 200 includes a collection funnel 8.1, which corresponds one-to-one with the hexagonal prisms of the honeycomb breeding box 100 and is connected as a whole. The collection funnel 8.1 has a hexagonal pyramid structure with smooth sidewalls, maintaining an inclination angle of 30°-40°. This utilizes gravity to allow solid waste, such as uneaten feed and feces, which are heavier than water, to naturally settle and slowly slide to the bottom of the collection funnel 8.1. A movable screen 9 is installed at the bottom of the collection funnel 8.1, and the lower part of the movable screen 9 is connected to a sewage pipe 8 and a sewage pump 10. The sewage pipe 8 extends from the bottom of the collection funnel 8.1 to the water surface, discharging the solid waste to a filter tower for filtration and collection.

[0031] like Figure 3 As shown, the water circulation system 300 includes a flushing pipe system, a water supply pipe 11, and a booster pump 4. The flushing pipe system consists of a main water pipe 6 and multiple circular branch nozzles 7. The number of branch nozzles 7 is determined by the height of the housing. The main water pipe 6 is a PVC pipe with an inner diameter of 5cm, and it is placed vertically on the inner wall of each hexagonal prism of the honeycomb breeding box. Multiple circular branch nozzles 7 with an inner diameter of 2.5cm are installed at equal intervals along the vertical direction of the main water pipe 6. Every 10cm on the branch nozzles 7, there is an oblique spray hole with a diameter of about 0.5cm to form a circulation. By controlling the booster pump 4, the surface water of the pond is mixed with the external oxygen source in the Venturi mixer 5 to obtain oxygenated water. The oxygenated water is then fed into the main water pipe 6 and flows to the three branch nozzles 7. The oxygenated water flows from bottom to top, and the overflowing water flows out through the fishing net 2, thus realizing the supply and flow of oxygenated water in the honeycomb breeding box 100.

[0032] like Figure 4 As shown, the mobile monitoring vessel 400 includes: a hull 16, an integrated sensor 15, and a power supply-wireless positioning and control module 19.

[0033] The hull 16 is a catamaran, which is wave-resistant and has good stability. A frame 14 is fixed to the hull 16, and a propeller 12 driven by a waterproof aviation motor is mounted on the frame 14. The other end of the waterproof aviation motor is connected to the output of a second servo motor 17 via a connecting plate. The propeller 12 driven by the waterproof aviation motor is steered in opposite directions by the second servo motor 17. The propeller 12 driven by the waterproof aviation motor is not in the water, thus preventing damage to the aquaculture organisms.

[0034] An integrated sensor 15 is installed in the space between the hull 16 and rotated by a first servo motor 13. During detection, the integrated sensor 15 is lowered into the water by rotating the first servo motor 13; when not detecting, the integrated sensor 15 is lifted out of the water by the first servo motor 13, reducing the chance of algae growth and facilitating the movement of the mobile monitoring vessel 400 within the honeycomb aquaculture box 100.

[0035] The integrated sensor 15 integrates multiple sensors such as dissolved oxygen, ammonia nitrogen content, dissolved salt, pH value, water transparency, and temperature through a PCB board.

[0036] The integrated sensor 15 can use the AMT-W400 multi-parameter water quality sensor, and 2-7 water quality sensors can be freely combined and installed. The monitoring factors include: temperature, pH, ORP, conductivity, salinity, dissolved oxygen, turbidity, chlorophyll a, blue-green algae, rhodamine, oil in water, ammonia nitrogen, etc.

[0037] The power supply-wireless positioning and control module 19 uses a 24V high-capacity aviation lithium battery. It provides 3.3V to the control system, 12V to the integrated sensor 15, and 22.2V to the waterproof aviation motor, the first servo motor 13, and the second servo motor 17 through a voltage regulator chip.

[0038] The wireless positioning module UWB in the power supply-wireless positioning and control module 19 is the existing Blue Dot Infinite BP-TWR-50 high-precision positioning module, which can directly locate.

[0039] The control module in the power supply-wireless positioning and control module 19 is an STM32-F103 microcontroller.

[0040] The control module in the power supply-wireless positioning and control module 19 is also connected to a signal transmission antenna. This signal transmission antenna is a high-powered antenna, such as the AZ-004G01 type, which has advantages such as a wide frequency range and low impedance. The signal transmission antenna is wirelessly connected to the signal receiving antenna of the remote control.

[0041] The remote controller transmits control signals to the signal transmission antenna via the signal receiving antenna, which can control the STM32-F103 microcontroller to drive the waterproof aviation motor, the first servo motor 13, and the second servo motor 17.

[0042] The integrated sensor 15 transmits data to the power-wireless positioning and control module 19 via a communication protocol. The power-wireless positioning and control module 19 filters the data and encapsulates it into JSON format. Then, it transmits the data to the ESP8266WiFi module via serial communication. The ESP8266WiFi module then communicates with the user's Alibaba Cloud IoT platform via the MQTT protocol, allowing the data to be transmitted to the Alibaba Cloud for processing. The user can receive the data via a WeChat mini-program on their mobile phone using the MQTT protocol for remote data monitoring.

[0043] Based on the data collected by the wireless positioning module UWB and the integrated sensor 15 in the power-wireless positioning and control module 19, the system determines the amount of water and air to be turned on in the water circulation system 300 in a specific location of the honeycomb breeding box 100, so as to reduce energy consumption while ensuring water quality.

[0044] The power supply-wireless positioning and control module 19 can control the rise and fall of the integrated sensor 15 by manipulating the first servo motor 13 to deflect up and down according to remote control commands or programs, control the forward and backward movement of the hull by using the forward and reverse rotation of the propeller driven by the waterproof aviation motor, and control the hull to turn left and right by manipulating the second servo motor 17 to drive the propeller driven by the waterproof aviation motor to deflect left and right.

[0045] The remote control used is the Yunzhuo H16 remote control, which can control drones and unmanned boats.

[0046] The remote control is equipped with a signal receiving antenna, which adopts a high-power signal transmission antenna such as the AZ-004G01, which has the advantages of wide frequency range and low impedance.

[0047] From the fry stage to maturity, the aquaculture system is responsible for providing a living environment for the fish, while the monitoring system is responsible for monitoring the quality of the fish's living environment in real time.

[0048] Taking the growth cycle of a single fish fry as an example, we will explain the working process and principle of this device:

[0049] Fish fry are placed in honeycomb rearing boxes 100 and fed regularly every day. A mobile monitoring vessel 400 patrols the fishpond daily, monitoring indicators such as dissolved oxygen, turbidity, pH value, dissolved salt, ammonia nitrogen content, and temperature in the fish farming environment. After the monitoring is completed, the data is uploaded to the cloud, and the user can adjust the environment according to the requirements of the fish farming environment.

[0050] 1) Fish fry stocking, feeding, and harvesting: The target yield is 1-2 tons of fish products per honeycomb partition. The initial stocking quantity is calculated based on the annual net weight gain multiple of different fish species and sizes. Commercially available extruded feed is used, and the fish are fed according to their habits. The fish are harvested at maturity.

[0051] 2) Water circulation: The water circulation system 300 is running at all times to ensure that the water in the honeycomb breeding box 100 is always in a circular flow state.

[0052] 3) Mobile monitoring vessel 400 patrol and detection: The mobile monitoring vessel 400 obtains its location through its onboard power-wireless positioning and control module 19. The integrated sensor 15 collects environmental factor data from the honeycomb breeding box 100, transmits it to the Internet of Things platform via WiFi module, and then transmits the data to a WeChat mini-program for processing and display using the MQTT protocol. Based on the processing results, it sends instructions to other systems to improve the environment of the honeycomb breeding box 100. If the transmitted monitoring data shows that the dissolved oxygen in the water of a honeycomb breeding box 100 at a certain address is low, the external oxygen supply at the gas inlet of the Venturi mixer 5 of that honeycomb is increased. If the data shows that multiple indicators such as pH, dissolved oxygen, ammonia nitrogen content, temperature, and turbidity value deviate from normal values, the speed of the booster pump 4 and the external oxygen supply are increased simultaneously to accelerate water circulation and increase dissolved oxygen. If the water quality is good, the pump speed and external oxygen supply can be reduced to save energy and reduce consumption.

[0053] 4) Solid waste collection and discharge: The solid waste collection and discharge system 200 is opened daily for 103-5 minutes to discharge waste, filtering and collecting it as fertilizer. Water-soluble wastes such as ammonia nitrogen are self-purified by the pond water outside the honeycomb breeding boxes.

[0054] Due to good oxygen supply, efficient water circulation, and timely removal of solid waste to prevent water pollution, a single honeycomb breeding box can achieve a stocking density 3-5 times higher than that of a pond of the same area. Multiple honeycomb breeding boxes can be combined for large-scale, high-density aquaculture in vast waters. Utilizing mobile monitoring vessels for patrol and detection saves on the high cost of fixed sensors while reducing energy consumption by more than 20% compared to conventional high-density aquaculture.
