Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a digitalized salmon fertilized egg and larval incubator. Background Technology

[0002] Salmon is an important economic fish species globally, and its aquaculture industry is developing rapidly. The hatching of fertilized eggs and the early rearing of larvae are among the most fundamental, delicate, and crucial links in the entire aquaculture chain. The survival rate and fry quality at this stage directly determine the success or failure of subsequent aquaculture and economic benefits.

[0003] Currently, salmon egg incubation commonly employs a flow-through model, using vertical tray incubators or parallel culture tanks. However, these traditional devices have several inherent drawbacks: First, environmental control precision is low; key parameters such as water temperature, dissolved oxygen, and water flow rely on manual experience for adjustment, making it difficult to maintain stability and meet the differentiated needs of fertilized eggs and larvae at different developmental stages. Second, water quality management is rudimentary, with direct discharge of aquaculture wastewater leading to significant water waste, and a lack of online removal and monitoring methods for harmful substances such as ammonia nitrogen and organic matter. Third, data utilization is insufficient; a systematic data collection and analysis mechanism is lacking, and operational status relies on manual inspection, making it difficult to detect abnormalities in a timely manner. Fourth, early warning and emergency response capabilities are weak; sudden water quality deterioration or equipment failure often leads to large-scale mortality and heavy losses. Fifth, the labor intensity is high; daily operations such as water changes, cleaning, and transfer are cumbersome, especially during the transfer of incubation trays, which can easily cause water outages and mechanical damage.

[0004] To address the aforementioned issues, some recirculating aquaculture systems have been applied to the hatching of fertilized eggs from other fish species, such as eels and spiny loaches. These systems integrate incubators, water treatment facilities, and circulation pipelines, achieving preliminary recycling of water resources and limited purification of water quality. However, existing solutions still cannot simultaneously solve the following technical challenges: how to ensure highly uniform water flow distribution and dissolved oxygen consistency across multiple layers in a multi-layered vertical structure; how to efficiently remove solid waste and dissolved organic matter without damaging fragile eggs and larvae; and how to automatically adjust environmental parameters based on biological behavior and water quality changes to achieve true preventative management rather than reactive response.

[0005] In view of this, there is an urgent need for a digital incubator designed specifically for the physiological characteristics of salmon fertilized eggs and larvae, which integrates precise environmental control, intelligent feedback regulation and efficient water treatment to fundamentally solve the prominent problems of traditional equipment such as extensive environmental control, weak larval management and high dependence on manual labor.

[0027] Compared with the prior art, the present invention discloses at least the following beneficial effects: This invention constructs a self-closed aquaculture water recycling system by organically combining the incubation unit with a circulating water treatment loop. A water purification tank, a rotary drum microfilter, a protein skimmer, an MBBR fluidized bed, a temperature control device, and a UV sterilizer are connected in series. This allows the aquaculture wastewater to undergo solid-liquid separation, removal of dissolved organic matter, ammonia nitrogen bioconversion, temperature regulation, and sterilization before flowing back to the water purification tank. This achieves fully automated circulating purification of aquaculture water, fundamentally solving the problems of high water consumption and difficulty in maintaining stable water quality in traditional flow-through systems. Simultaneously, the multi-tiered tray incubator structure supported by the tiered incubator frame provides a well-organized cultivation space for fertilized eggs and larvae. Combined with the continuous flow of the circulating water circuit, this ensures that the water in each tray is constantly circulating and renewed, preventing localized water quality deterioration. The synergistic cooperation between the circulating water treatment loop and the tray slot insertion structure allows the incubator to maintain a stable water quality environment during continuous operation, creating safe and continuous physical conditions for fertilized egg hatching and early larval development, effectively improving hatching rate and fry survival rate.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 As shown, this embodiment provides a digitalized salmon fertilized egg and larval incubator, including an incubation unit, a water treatment unit, and a feedback regulation unit. The incubation unit provides the physical space and water flow environment for incubating fertilized eggs and raising larvae, the water treatment unit circulates and purifies the aquaculture water, and the feedback regulation unit monitors and intelligently controls the incubation environment parameters in real time.

[0033] In one specific embodiment, the incubation unit employs a novel shelf-type incubator, including a tray incubator 5, a shelf-type incubator frame 6, a flow control system, and a fully automatic cleaning and sewage discharge system.

[0034] Specifically, the main body of the tray incubator 5 is made of a biocompatible transparent polymer material, such as polycarbonate (PC) or polymethyl methacrylate (PMMA), to facilitate direct observation of the developmental status of the fertilized eggs and larvae inside the tray.

[0035] Based on the above embodiments, the tray incubator 5 adopts an integrated incubation and transfer tray structure, with a replaceable graded microporous sieve plate at the bottom. The sieve plate has a pore size range of 0.5mm to 2.0mm to adapt to the size requirements of different developmental stages from fertilized eggs to larvae.

[0036] In one specific implementation, when the hatching target is fertilized eggs, a sieve plate with a pore size of 0.5 mm is selected to prevent the eggs from leaking out; when the hatching target develops into larvae, a sieve plate with a larger pore size can be used to ensure smooth water flow.

[0037] Based on the above embodiments, the bottom of the tray adopts an anti-fouling sloping design, and a quick-connect self-sealing water valve is installed at the bottom of the sloping bottom. This self-sealing water valve adopts a mechanical linkage design. When the tray incubator 5 is vertically inserted into the slot of the shelf incubator frame 6, the pushing component on the shelf incubator frame 6 pushes open the valve core of the self-sealing water valve, allowing the water path to be opened. When the tray incubator 5 is pulled out from the shelf incubator frame 6, the valve core quickly returns to its original position under the action of the return spring, achieving double sealing.

[0038] Through the above structure, the tray incubator 5 can achieve "waterless and damage-free transfer", effectively overcoming the technical problem that traditional incubators cause the death of fertilized eggs or fry due to water shortage or lack of oxygen during the transfer process, and greatly improving the transfer survival rate.

[0039] In one specific embodiment, the shelf-type incubator frame 6 is a vertical array incubation frame, which adopts a high-strength corrosion-resistant metal skeleton, preferably made of stainless steel.

[0040] Based on the above embodiments, the shelf-type incubator frame 6 is provided with a multi-layer tray slot structure for vertically inserting multiple tray incubators 5.

[0041] Building upon the aforementioned embodiments, the shelf-type incubator frame 6 further integrates a Venturi-type gas-water mixing header and independent branch pipe systems corresponding to the slots of each tray. The gas-water mixing header connects to external gas and water sources, and after fully mixing the gas and water through the Venturi effect, the mixture is delivered to each tray via the independent branch pipes. The header's flow guiding structure is optimized, and combined with an inter-layer flow counterweight mechanism, the water flow uniformity deviation of each tray unit can be controlled within 5%, ensuring the consistency of dissolved oxygen levels across all layers.

[0042] The design of the above-mentioned flow equalization and low resistance architecture effectively overcomes the water pressure imbalance problem caused by the height difference in the multi-layer vertical structure, and provides a highly consistent physical environment for each layer of tray incubator 5, thereby ensuring the consistency of incubation conditions for each batch of fertilized eggs.

[0043] Based on the above embodiments, such as Figure 1 As shown, the intelligent salmon fertilized egg and larvae incubator provided in this embodiment also includes a support frame 12. The support frame 12 is located at the bottom of the air conditioner 1, the ultraviolet sterilizer 2, and the water purification tank 3, and is used to provide stable support for the above-mentioned equipment.

[0044] Furthermore, the support frame 12 is constructed from high-strength stainless steel profiles, welded or bolted together, possessing sufficient structural strength and corrosion resistance to withstand the operating weight of each piece of equipment and the vibrations generated during operation. Through the integrated support of the support frame 12, the components of the entire water treatment unit and hatching unit are rationally elevated and arranged in an orderly manner. This provides ample operating space for the pipe connections at the bottom of each piece of equipment, facilitating pipe installation, maintenance, and repair. It also allows the connecting pipes between the equipment to be laid at the designed slope, ensuring smooth gravity flow of the aquaculture water. In addition, the design of the support frame 12 makes the entire system compact and clearly laid out, facilitating modular arrangement and rapid assembly / disassembly of equipment within a limited space.

[0045] Building upon the aforementioned embodiments, the flow control system further employs an architecture combining a variable frequency main pump and a digital valve array. Each independent branch pipe corresponding to the tray incubator 5 is equipped with an independent electric regulating valve, forming a digital valve array. Based on real-time water quality and flow data fed back from sensors, the system adjusts the total water supply flow through the variable frequency main pump and controls the opening degree of each electric regulating valve individually to achieve precise and independent control of the flow in each branch. Through dynamic hydraulic balancing technology, the system effectively overcomes the water pressure imbalance problem caused by height differences in vertical multi-layer structures, supporting flexible settings of custom flow modes. For example, when enhanced bottom-level sewage discharge is required, the flow rate of the bottom-level branch pipes can be increased independently.

[0046] Building upon the above embodiments, the fully automated cleaning and sewage discharge system further includes dedicated sewage discharge channels located at the junctions of each tray and the shelf-type incubator frame 6. The system also includes differential pressure sensors, a controller, and an electric sewage discharge valve. The differential pressure sensors are located on both sides of the filter unit to monitor the pressure difference across the filter unit in real time. The controller intelligently determines the cleaning timing based on the signals from the differential pressure sensors and a preset dirt deposition prediction model. When the triggering conditions are met, the controller initiates a targeted backwashing program to backwash the filter unit and simultaneously initiates a pulse water flow cleaning program to clean the inside of the pipeline. The dirt generated during cleaning collects in a collection trough at the bottom of the shelf-type incubator frame 6 and is discharged periodically by the electric sewage discharge valve.

[0047] The aforementioned intelligent sewage discharge triggering logic integrates a sewage deposition prediction model with real-time turbidity monitoring data, which can dynamically optimize the timing and intensity of cleaning, significantly reduce the frequency of ineffective flushing, and effectively maintain the long-term stability of water parameters while reducing system energy and water consumption.

[0048] In one specific embodiment, the water treatment unit includes an influent water treatment subunit and a circulating water treatment subunit.

[0049] Based on the above embodiments, the influent treatment subunit includes a sand filter tank, an activated carbon adsorption device, an ozone sterilization device, and an aeration and degassing device connected sequentially via pipelines. External water is first introduced into the sand filter tank for primary filtration to remove large suspended solids. Then, it sequentially passes through activated carbon adsorption to remove residual chlorine and organic matter, ozone sterilization to inactivate pathogenic microorganisms, and aeration and degassing to remove residual ozone and harmful gases. After the above treatment, the treated water enters the water quality testing stage.

[0050] Furthermore, the influent water treatment subunit is also equipped with an intelligent water quality detector and a pipeline backflow switch. When the intelligent water quality detector detects that a certain water quality parameter does not meet the standard, it triggers the control system to open the pipeline backflow switch, causing the substandard water to flow back to the sand filter tank for reprocessing until the water quality meets the standard before it can enter the clean water tank 3 for storage and backup, thus ensuring the safety of the water used for seedling hatching from the source.

[0051] Based on the above embodiments, the circulating water treatment subunit includes a water purification tank 3, a rotary drum microfilter 11, a protein separator 8, an ultraviolet sterilizer 2, an MBBR fluidized bed 9, an aeration fan, a temperature control system, and an external wastewater collection tank. Aquaculture water flows out of the water purification tank 3, passes through a zoned inlet trough 4, and enters a novel shelf-type incubator (i.e., a combination of a tray incubator 5 and a shelf-type incubator frame 6). The overflow from the incubator first enters the rotary drum microfilter 11 for primary filtration. After filtering out solid particles, the filtrate flows into the wastewater tank 10. The rotary drum microfilter 11 has a filter mesh size of 200 μm and a filtration area of ​​5 m². 2 Filtration capacity is 50m 3 / h.

[0052] Based on the above embodiment, water in the tailrace tank 10 is pumped into the protein skimmer 8 by the pump 7. The protein skimmer 8 is used to remove dissolved organic matter from the water, with a treatment capacity of 10 t / h, container dimensions of Φ200 mm × H1200 mm, air intake of 1000 ml / min, and a reaction time of 2 min. The water treated by the protein skimmer 8 flows into the MBBR fluidized bed 9, where the ammonia nitrogen in the water is converted into nitrate by the microbial film on the surface of the biological packing material, achieving effective ammonia nitrogen removal. The purification capacity of the MBBR fluidized bed 9 is 50 m³ / h. 3 / h. Water treated by the MBBR fluidized bed 9 passes sequentially through the air conditioning unit 1 for temperature control and the ultraviolet sterilizer 2 for disinfection, and finally flows back to the clean water tank 3, completing one cycle of treatment. Approximately 10% of the system water is discharged to an external wastewater collection tank to control the concentration of cumulative pollutants such as nitrates in the circulating water.

[0053] The entire water treatment unit constructs a four-stage cascaded purification chain: a pre-filter with low suction vortex solid waste collection → a freshwater-optimized protein separator → mechanical filtration with composite filter media → fluidized bed bioconversion, combined with a high-efficiency ultraviolet sterilization module, achieving an integrated water treatment effect of "low disturbance - high-efficiency purification". The pre-filter with low suction vortex solid waste collection effectively solves the problem of physical damage to fragile eggs and seedlings caused by traditional filtration systems, minimizing disturbance to organisms while ensuring purification efficiency.

[0054] In one specific embodiment, the feedback regulation unit includes a system temperature control module, a digital control module, and an intelligent environmental factor regulation module.

[0055] Based on the above embodiments, the system temperature control module employs a high-precision temperature sensor array in conjunction with the air conditioning unit 1 to monitor the ambient temperature of the incubation area in real time. The temperature sensor array is positioned near each layer of tray incubator 5, transmitting the collected temperature data to the controller. The controller, based on preset temperature requirements for the fertilized eggs and larvae, uses the air conditioning unit 1 to dynamically and precisely control the temperature of each area in a zoned manner, with a temperature control accuracy of ±0.5℃. In one specific embodiment, the suitable temperature for the fertilized egg incubation stage is 5~10℃, and the suitable temperature for the larvae rearing stage is 10~13℃. The controller automatically switches the temperature setpoint according to the current rearing stage. The shelf-type incubator frame 6 also has a physical partition structure inside to reduce thermal interference between different areas.

[0056] Through the aforementioned fully automatic time-sharing and zone-based temperature control technology, the system breaks through the limitations of the traditional overall constant temperature mode, accurately meets the optimal temperature requirements of different developmental stages, and effectively improves the hatching rate and seedling quality.

[0057] Building upon the above embodiments, the digital control module further integrates multi-source sensor data based on an IoT architecture. These multi-source sensors include a temperature sensor, a dissolved oxygen sensor, a pH sensor, and a flow sensor, used to collect environmental parameters such as temperature, dissolved oxygen levels, pH value, and water flow rate within the incubator. The sensor data is received by the edge computing unit, which then runs a multi-factor collaborative algorithm. Based on the algorithm's results, the edge computing unit dynamically adjusts the operating states of actuators such as the variable frequency main pump, electric regulating valve, gas valve, and temperature control module, forming a closed-loop feedback control.

[0058] The aforementioned digital control module achieves "coupled regulation of environmental factors," automatically optimizing dissolved oxygen supply intensity and water flow velocity based on the logical relationship between salmon biological behavior data (such as feeding status) and water quality parameters. This significantly reduces the frequency of human intervention and realizes comprehensive digitalization and intelligentization of hatching management. The edge computing unit also connects to the cloud platform via a communication module, enabling remote diagnosis and strategy iteration.

[0059] Building upon the aforementioned embodiments, the intelligent environmental factor control module further utilizes a pre-built salmon hatching knowledge graph database and employs a lightweight AI model to analyze and process real-time data streams. This AI model can identify abnormal trends in the data and provide early warnings of such trends, such as predicting the gradual decrease in dissolved oxygen. Simultaneously, based on historical fault modes and an expert rule base, the system can proactively push cleaning and maintenance suggestions or environmental parameter correction plans, realizing a "preventive control mechanism." This effectively reduces the risk of deformity and mortality, significantly improving the stability and safety of the hatching process.

[0060] By combining the above technical solutions, this invention realizes the recycling of aquaculture water and fully automated operation. While significantly improving the hatching rate and fry survival rate, it effectively reduces system energy and water consumption, reduces wastewater discharge, promotes the intelligent upgrading of the salmon seed hatching process, and has significant economic benefits and environmental value.

[0061] In a specific application scenario, such as Figure 1 As shown, the operation flow of this embodiment is as follows: External water sequentially passes through a sand filter, activated carbon adsorption device, ozone sterilization device, and aeration / deaeration device. After passing water quality testing, it enters the clean water tank 3. The aquaculture water in the clean water tank 3 overflows into the zoned inlet tank 4, and then flows by gravity to the tiered incubator frame 6. The water is evenly distributed to each tray incubator 5 via a zoned flow meter. Aquaculture wastewater overflows through the drain pipe 13 to the rotary drum microfilter 11, undergoes primary filtration, and then flows into the wastewater pool 10. Water in the wastewater pool 10 is pumped by the water pump 7 into the protein skimmer 8 to separate and remove dissolved organic matter. The treated water enters the MBBR fluidized bed 9 to convert and remove ammonia nitrogen. The treated water is then temperature-controlled by the air conditioning unit 1, flows into the ultraviolet sterilizer 2, and finally returns to the clean water tank 3, achieving fully automated recirculating aquaculture and incubation. Throughout the entire operation, the feedback regulation unit continuously monitors and automatically adjusts various environmental parameters to ensure the incubation environment is always maintained at its optimal state.

[0062] In an alternative embodiment, the MBBR fluidized bed 9 can be replaced with a fixed-bed biofilter, which can still achieve the bioconversion of ammonia nitrogen. In another alternative embodiment, the protein separator 8 can be replaced by a foam separator to remove dissolved organic matter. The aperture of the sieve plate at the bottom of the tray is not limited to the range of 0.5~2.0mm and can be adaptively adjusted according to the size of the actual incubated organisms.

[0063] In an extended implementation, the feedback control unit can also integrate a light intensity sensor to monitor and adjust the light intensity of the incubation environment to meet the light-shielded development requirements of salmon fertilized eggs. Specifically, the light intensity sensor collects ambient light data, and the controller automatically adjusts the opening of the shading mechanism or the brightness of the supplemental lighting according to a preset light threshold to maintain the light intensity within a suitable range.

[0064] In another extended implementation, the system can also be configured with a backup power supply and an emergency oxygenation device. When the main power supply fails, the backup power supply automatically switches to power, and at the same time, the emergency oxygenation device is activated to provide emergency oxygen supply to each layer of tray incubator 5, preventing sudden changes in the incubation environment due to power failure, thereby effectively ensuring the survival rate of fertilized eggs and larvae.
