Description

Technical Field

[0001] This invention relates to the field of environmental factor monitoring technology, and in particular to a device for monitoring environmental factors in the growth and cultivation of bream. Background Technology

[0002] The triangular bream, belonging to the Cyprinidae family and the genus *Brachys*, is widely distributed in most rivers and lakes of my country and is one of the country's important economic fish species. It inhabits the middle and lower layers of flowing or still water, preferring to fatten in open water areas with silt and submerged vegetation. It requires high water quality; clean water and high dissolved oxygen levels are essential for its survival. It is an omnivorous fish, primarily feeding on cladocerans, *Vallisneria natans*, and *Hydrilla verticillata*, while also consuming freshwater shellfish, mollusks, and aquatic insects. Its diet is quite versatile, ranging from lower single-celled algae to higher invertebrates.

[0003] To quantify the carbon allocation during the growth and metabolism of bream and its relationship with intrinsic needs and environmental factors, and to reveal and predict the impact of environmental factors such as food availability and water temperature on individual carbon budgets, it is necessary to monitor environmental factors and carbon dioxide concentrations in bream water bodies, construct numerical models of individual carbon budgets, understand the key processes of bream biodeposition, strengthen basic research on the carbon sink function and carbon pathways of fisheries from both physiological ecology and biogeochemistry perspectives, comprehensively understand the contribution of fisheries to the carbon cycle of water bodies, and provide a basis for scientifically grasping the carbon cycle processes and mechanisms in inland waters.

[0004] Traditional environmental factor monitoring typically employs periodic sampling, with sampling intervals that can be quite long, such as every few days or weeks. This low-frequency sampling method cannot capture rapid changes in aquatic environmental factors that occur within a short period. Furthermore, the long sampling intervals mean that these changes may not be detected in a timely manner. If the monitoring equipment for monitoring aquatic environmental factors of the bream is immersed in water for a long period of time for real-time monitoring, various dirt and microorganisms will inevitably accumulate on its surface. These dirt and microorganisms may include silt, algae, bacteria, and other tiny organic and inorganic substances. Over time, these contaminants not only affect the appearance of the equipment but, more importantly, significantly impact the monitoring accuracy. For example, dirt may clog sensitive parts of the sensor, leading to inaccurate data readings; or it may alter the physical properties of the sensor surface, such as thermal conductivity or optical reflectivity, thereby interfering with the measurement results. In addition, long-term dirt accumulation may also lead to corrosion or damage to internal components of the equipment, further reducing the equipment's lifespan and reliability. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a monitoring device for environmental factors in the growth and cultivation of bream, aiming to solve the problems of traditional monitoring devices being difficult to monitor in real time and the easy accumulation of dirt on the sensor surface when immersed in water for a long time.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a monitoring device for environmental factors in the growth and cultivation of bream.

[0007] Preferably, the sensor assembly includes a water temperature sensor, a salinity sensor, a pH sensor, a dissolved oxygen sensor, and an ammonia nitrogen sensor. The data collected by the sensor assembly is transmitted to the user terminal via wireless or wired communication. The water temperature sensor monitors the water temperature to ensure it is within a suitable range; a thermistor or digital temperature sensor can be used. The salinity sensor monitors the water salinity; a conductivity sensor can be used. The pH sensor monitors the water acidity / alkalinity; the pH should be controlled between 6 and 8; a glass electrode pH sensor can be used. The dissolved oxygen sensor ensures that the dissolved oxygen in the water is greater than 5 mg / L to meet the respiratory needs of the bream; an optical dissolved oxygen sensor or an electrochemical dissolved oxygen sensor can be used. The ammonia nitrogen sensor monitors the ammonia nitrogen and nitrite content in the water to prevent water quality deterioration; an electrochemical sensor or a colorimetric sensor can be used.

[0008] Preferably, the monitoring platform has pontoons fixed to both sides of the array. The pontoons are filled with gas, which provides sufficient buoyancy to keep the platform stable on the water surface. By adjusting the amount of gas in the pontoons, the height and stability of the entire platform can be adjusted to adapt to different water depths and fluctuations. The connection between the pontoons and the platform is usually made of a fixed ring or telescopic rod, which facilitates installation and disassembly. The gas inside the pontoons can be adjusted by a one-way pressure valve or a water pump, which facilitates maintenance and repair.

[0009] Preferably, a telescopic waterproof plate is fixed to the other end of the slider. The telescopic waterproof plate is composed of multiple telescopic plates, and each telescopic plate is connected by a flexible connector to ensure that it remains sealed during the telescopic process. It is designed to telescopically extend and retract with the slider, always keeping the area above the lead screw closed to prevent water from entering and to protect the lead screw and transmission components from water corrosion. One end of the telescopic waterproof plate is fixed to the slider, and the other end is fixed to the side wall of the slide block.

[0010] Preferably, a photovoltaic panel is fixed in the empty area on top of the monitoring floating platform. The output terminals of the photovoltaic panel are electrically connected to an inverter and a battery, respectively. The output terminal of the battery is electrically connected to the inverter.

Together with the inverter, they form a complete power supply system to ensure continuous power supply to the electrical equipment on the floating platform and ensure that the floating platform can still work normally under no-sunlight conditions.

[0011] Preferably, a waterproof box is fixed to the surface of the cleaning pump, and waterproof motor housings are fixed to the surfaces of both the lead screw drive motor and the integrated board drive motor. The waterproof box is used to protect the electrical components of the pump and prevent water from entering. The waterproof box has an IP68 waterproof rating. The waterproof motor housing is used to protect the internal components of the motor and prevent water from entering. It also has an IP68 waterproof rating and is made of corrosion-resistant materials. A water-blocking ring or rain cap is installed on the shaft extension of the motor to form the first waterproof barrier. The shaft oil seal is made of dustproof and waterproof material to reduce the possibility of water penetration.

[0012] Preferably, the monitoring floating platform is made of high-density polyethylene, fiberglass, or plastic. Floating platforms made of high-density polyethylene possess excellent weather resistance and impact resistance. Their lightweight and high-strength characteristics ensure stability in various harsh environments and facilitate installation and maintenance. Fiberglass has high strength and corrosion resistance, making it suitable for complex environments. Its good mechanical properties and anti-aging capabilities ensure structural stability and reliable function during long-term use. Plastic materials are widely used in the manufacture of monitoring floating platforms due to their lightweight, durability, and low cost. Plastic materials also have good corrosion resistance, making them suitable for prolonged immersion in water, ensuring the service life of the floating platform.

[0014] Preferably, both the inlet and outlet pipes are connected to solenoid valves. The solenoid valves in the inlet and outlet pipes are used to control the flow of water. The valve core is opened and closed by electrical signals to achieve automated management and improve system efficiency and safety.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This monitoring equipment integrates sensors for carbon dioxide concentration, water temperature, salinity, pH, dissolved oxygen, and ammonia nitrogen into one unit. Through a floating platform design, coupled with a screw drive and rotation mechanism, the sensors can be immersed in water for long-term monitoring, facilitating the real-time capture of changes in aquatic environmental factors. A cleaning mechanism allows for convenient cleaning of the sensor surfaces. After a period of operation, the rotating and cleaning mechanisms work together to flush away dirt and microorganisms from the sensor surfaces, preventing dirt from affecting sensor accuracy and preventing corrosion and damage to internal components, thus extending sensor lifespan. This further enables more accurate and convenient subsequent assessment of the impact of environmental factors on the carbon budget of individual bream, facilitating the construction of a numerical model of the bream's individual carbon budget. This provides support for obtaining key technical parameters of bream in promoting carbon sink fisheries, strengthening the biological carbon sink function of fisheries, and identifying carbon sink pathways, further optimizing my country's large-scale water-based stock enhancement and release ecological fishery model.

A sensor assembly 9 and a carbon dioxide concentration sensor 10 are arrayed and fixed to the end of the integrated plate 11 away from the slider 8. A telescopic waterproof plate 3 is fixed to the other end of the slider 8. The telescopic waterproof plate 3 consists of multiple telescopic plates, each connected by flexible connectors such as rubber or silicone sealing strips to ensure a seal during telescopic movement. It is designed to telescopically extend and retract with the slider 8, always maintaining a closed state above the lead screw 15 to prevent water from entering and protecting the lead screw and transmission components from water corrosion. One end of the telescopic waterproof plate 3 is fixed to the slider 8, and the other end is fixed to the side wall of the slide block 2. Cleaning pumps 14 are fixed at both ends of the top of the monitoring floating platform 1, and are mirror-distributed on both sides of the slide 2. The output end of the cleaning pump 14 is connected to the water outlet pipe 1402, and the output end of the water outlet pipe 1402 is connected to the cleaning nozzle 13. The input end of the cleaning pump 14 is connected to the water inlet pipe 1401. Solenoid valves are connected to the surfaces of the water inlet pipe 1401 and the water outlet pipe 1402. The solenoid valves in the water inlet pipe 1401 and the water outlet pipe 1402 are used to control the flow of water. The valve core is controlled to open and close by an electrical signal to achieve automated management and improve system efficiency and safety. When the solenoid valves of the cleaning pump 14 and the water inlet pipe 1401 are opened, water is drawn in. A filter screen is installed inside the water inlet pipe 1401 to filter impurities in the water. The control integrated board drive motor 1101 rotates the integrated board 11 to align it with the cleaning nozzle 13. The cleaning nozzle 13 is used to clean the surface dirt of the sensor assembly 9 and the carbon dioxide concentration sensor 10. A lead screw 15 is connected to the bearing and driven by a lead screw drive motor 16. The lead screw 15 is threadedly connected to the middle of the slider 8. The lead screw drive motor 16 drives the lead screw 15 to rotate, which moves the slider 8 and the integrated sensor assembly to the periphery of the floating platform. In conjunction with the integrated board drive motor 1101, the integrated board 11 is rotated, allowing the sensor assembly 9 to be immersed in water for monitoring. A waterproof box 4 is fixed to the surface of the cleaning pump 14. Both the lead screw drive motor 16 and the integrated board drive motor 1101 are fixed to waterproof motor housings. The waterproof box is used to protect the electrical parts of the pump and prevent water from entering. The waterproof box has an IP68 waterproof rating. The waterproof motor housing is used to protect the internal components of the motor and prevent water from entering. It also has an IP68 waterproof rating and is made of corrosion-resistant materials. A water-blocking ring or rain cap is installed on the shaft extension of the motor to form the first waterproof barrier. The shaft oil seal is made of dustproof and waterproof material to reduce the possibility of water penetration.Anchor bolts 12 are fixed to the perimeter of the monitoring floating platform. The anchor bolts 12 are evenly distributed along the edge of the platform to provide stable support and fixation. Each anchor bolt 12 is firmly fixed with a tough anchor rope 5. These anchor ropes 5 are specially treated to have high strength, wear resistance, and corrosion resistance, and can be used for a long time in harsh aquatic environments without easily being damaged. An anchor hook 6 is fixed to the end of the anchor rope 5. This design allows the anchor hook 6 to penetrate deep into the mud at the bottom of the river, forming a stable anchoring effect. By fixing the anchor hook 6 to the bottom of the river, the combination of anchor rope 5 and anchor hook 6 also has a certain degree of elasticity, which can absorb and mitigate the impact from water flow and waves to a certain extent, reducing the impact on the floating platform. This design not only improves the service life of the floating platform, but also effectively prevents the floating platform from drifting or tilting under the action of water flow or waves, ensuring the stability and safety of the floating platform.

[0029] All sensor components 9 have an IPX8 waterproof rating. IPX8 is a protection rating standard set by the International Electrotechnical Commission. Devices of this rating can still work normally after being submerged in water for a long time. It is suitable for underwater equipment and high humidity environments, ensuring the long-term reliability of the sensor components and effectively preventing water penetration that could cause failure. Sensor component 9 includes a water temperature sensor, a salinity sensor, a pH sensor, a dissolved oxygen sensor, and an ammonia nitrogen sensor. The data collected by sensor component 9 is transmitted to the user terminal via wireless or wired communication. The water temperature sensor monitors the water temperature to ensure it remains within a suitable range; a thermistor or digital temperature sensor can be used. The salinity sensor monitors the water's salinity; a conductivity sensor can be used. The pH sensor monitors the water's acidity / alkalinity; the pH should be controlled between 6 and 8; a glass electrode pH sensor can be used. The dissolved oxygen sensor ensures the dissolved oxygen in the water is greater than 5 mg / L to meet the respiratory needs of the bream; an optical or electrochemical dissolved oxygen sensor can be used. The ammonia nitrogen sensor monitors the ammonia nitrogen and nitrite content in the water to prevent water quality deterioration; an electrochemical or colorimetric sensor can be used. The sensor also integrates data from carbon dioxide concentration, water temperature, salinity, and pH. The sensor, dissolved oxygen sensor, and ammonia nitrogen sensor are integrated into one unit. Through a floating platform design, combined with a screw drive mechanism and a rotating mechanism, the sensor can be immersed in water for long-term monitoring in real time. This facilitates the real-time capture of changes in aquatic environmental factors. The cleaning mechanism allows for easy cleaning of the sensor surface. After the sensor has been in operation for a period of time, the rotating and cleaning mechanisms work together to wash away dirt and microorganisms from the sensor surface, preventing dirt from affecting the sensor's accuracy and also preventing corrosion and damage to the internal components, thus extending the sensor's lifespan. This further enables more accurate and convenient subsequent assessment of the impact of environmental factors on the carbon budget of individual bream, and allows for the construction of a numerical model of the carbon budget of individual bream. This provides support for obtaining key technical parameters of bream in promoting carbon sink fisheries, strengthening the biological carbon sink function of fisheries, and carbon sink pathways, and further optimizes the large-scale water-based stock enhancement and release ecological fishery model in my country.
