Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an integrated breeding pond for raising giant freshwater prawns. Background Technology

[0002] As a freshwater aquaculture species with high economic value, the scale of aquaculture of giant freshwater prawns has been expanding in recent years. In the current aquaculture practice of giant freshwater prawns, the industry generally adopts a model of separating aquaculture and breeding. That is, the seedlings of giant freshwater prawns are raised in special breeding facilities, and after the seedlings have been raised to a certain stage, they are transferred to special aquaculture facilities for subsequent adult shrimp farming.

[0003] However, this separate breeding and aquaculture model has many inherent drawbacks, causing numerous inconveniences for aquaculture practitioners. First, the separation of breeding and aquaculture makes the overall workflow more cumbersome, requiring separate management, maintenance, and monitoring of breeding and aquaculture facilities, increasing the complexity of aquaculture management. Second, because the two stages belong to different facilities, the juvenile giant freshwater prawns obtained from breeding need to be transferred multiple times. The transfer process involves multiple operational steps such as harvesting, temporary holding, transportation, and release, which not only significantly increases the workload and labor intensity of aquaculture personnel and raises aquaculture costs, but more importantly, giant freshwater prawn juveniles are relatively weak and susceptible to environmental factors. The prawns have poor adaptability to environmental changes. Mechanical damage and environmental stress (such as changes in water temperature, water quality, and dissolved oxygen) during multiple transfers can easily cause stress reactions in the larvae, leading to death and seriously affecting the survival rate of the larvae and the subsequent breeding benefits. It is evident that the existing technology lacks a pond structure that can integrate the breeding and aquaculture functions of the giant prawn, and cannot solve the technical problems of the existing separate breeding and aquaculture model, such as cumbersome operation, large workload, and high mortality rate of larvae during transfer. This restricts the efficient and high-quality development of the giant prawn aquaculture industry. Therefore, the development of a giant prawn integrated breeding and aquaculture pond has important practical significance and application value. Utility Model Content

A water level control pipe body is fixedly connected to the inside of the sedimentation pond body, and the bottom of the water level control pipe body is connected to the drain outlet of the culture pond body through the three-way pipe body.

[0011] Furthermore, a biochemical tank water level control pipe is fixedly connected to the bottom of the ultraviolet sterilization tank, and a temperature control water inlet is fixedly connected to one side of the regulating tank.

[0012] Furthermore, the inside of the regulating tank is fixedly connected to a flow regulating valve for aquaculture ponds, and the output end of the flow regulating valve is fixedly connected to a water inlet for aquaculture ponds. The water inlet for aquaculture ponds is connected to the inside of the aquaculture pond. The input end of the flow regulating valve for aquaculture ponds is provided with a temperature control reflux outlet.

[0013] The beneficial effects of this utility model are:

[0014] 1. During the application of this technical solution, by setting up an outer pool, an inner aquaculture pool, and various treatment pools in the cavity between the two, the breeding and aquaculture functions can be integrated into one during use. There is no need to build separate breeding facilities or transfer seedlings. At the same time, with the synergistic effect of fish toilets and three-way pipes, pollutants can be smoothly discharged and drainage switching can be controlled, thereby simplifying the aquaculture and breeding operation steps and reducing the complexity of management.

A water level control pipe 14 for the aquaculture pond is fixedly connected inside the sedimentation tank 7. The bottom of the water level control pipe 14 for the aquaculture pond is connected to the drain outlet 11 of the aquaculture pond through a three-way pipe 10. During the application of this device, by setting up an outer pond 1, an inner aquaculture pond 2, and a biological pond 3, a buffer pond 4, an ultraviolet sterilization pond 5, an regulating pond 6, and a sedimentation pond 7 arranged sequentially in the intervening cavities between them; and cooperating with the treatment pond partition 8, fish toilet 9, three-way pipe 10, aquaculture pond drain outlet 11, escape-proof frame 12, annular escape-proof net 13, and aquaculture pond water level control pipe 14, the breeding and aquaculture of giant freshwater prawns can be completed in the same device during use. When in use, the inner culture tank 2 can be directly used for the breeding and cultivation of giant freshwater prawns; no additional transfer of larvae is required; pollutants such as uneaten feed and feces generated during the breeding or cultivation process will be collected in the fish toilet 9 at the bottom center of the inner culture tank 2; after initial collection by the fish toilet 9, it will be discharged through the three-way pipe 10 at the output end; at the same time, the water in the sedimentation tank 7 can form a circulation with the inner culture tank 2 through the three-way pipe 10; the water level control pipe 14 of the culture tank can regulate the water level of the inner culture tank 2 to ensure the stability of the water environment; the treatment tank partition 8 separates the various functional tanks to ensure that the functions of each tank are performed in an orderly manner; the escape-proof frame 12 and the ring-shaped escape-proof net 13 on the top of the inner culture tank 2 can effectively prevent giant freshwater prawns from escaping.This structural design makes aquaculture and breeding operations more centralized and convenient; it reduces the cumbersome steps required for separate aquaculture and breeding; it lowers the risk of damage caused by transporting seedlings; at the same time, the synergistic effect of each pool can ensure the stability of the water quality environment in the inner aquaculture pool 2; it improves the safety of aquaculture and breeding; the cooperation between the three-way pipe 10 and the aquaculture pool drainage outlet 11 and the aquaculture pool water level control pipe 14 realizes the integration of water discharge and water level regulation; it further improves the convenience of use; it effectively solves the problems of cumbersome operation and inconvenient seedling transportation caused by separate aquaculture and breeding in the existing technology. During the application of this equipment, water pumps can be installed at the biochemical pool water level control pipe 20, the aquaculture pool water level control pipe 14 and the aquaculture pool flow regulating valve 22 as needed, or connected to external water supply and drainage equipment to facilitate water level control.

[0024] Combination Figures 1-3 As shown, a reinforcing ring 15 is fixedly connected to the top of the outer pool 1, a reinforcing bottom ring 16 is fixedly connected to the bottom of the inner aquaculture pool 2, a filter element 17 is fixedly connected to the inside of the filter pool 25, the input end of the filter pool 25 is connected to the sedimentation pool 7, the filter pool 25 is connected to the biological pool 3, the output end of the biological pool 3 is connected to the buffer pool 4, and the bottom of the buffer pool 4 is fixedly connected to the biological pool drain outlet 18.

[0025] In the above-described embodiments of this application, the device, through the installation of a reinforcing ring 15, a reinforcing bottom ring 16, a filter tank 25, a filter element 17, and a biological tank drain outlet 18, combined with the existing interconnections of the various tanks, further enhances the stability and water treatment effect of the device during use. During use, the reinforcing ring 15 at the top of the outer tank 1 strengthens the overall structural strength of the tank, preventing deformation under long-term water storage or external forces. The reinforcing bottom ring 16 at the bottom of the inner aquaculture tank 2 enhances the load-bearing capacity of the tank, ensuring the reliability of the device during long-term use. Simultaneously, the water in the sedimentation tank 7 flows into the connected filter tank 25, where it is filtered by the filter element 17 to remove impurities before flowing into the connected biological tank. The biological treatment tank 3 further processes the water to improve its purification effect. The water treated by the biological treatment tank 3 enters the connected buffer tank 4. The biological treatment tank drain 18 at the bottom of the buffer tank 4 can promptly discharge excess water or sediment impurities from the tank, preventing water stagnation and deterioration. This design not only makes the device structure more stable and extends its service life, but also optimizes the water treatment process through the filtration effect of the filter element 17 and the orderly connection of each tank, ensuring that the aquaculture water is clean and stable, providing a good environment for the growth of giant freshwater prawns. At the same time, the setting of the biological treatment tank drain 18 facilitates water regulation and impurity removal, reduces the tedious operation of manual maintenance, further improves the ease of use, and effectively improves the problems of insufficient device stability, incomplete water treatment, and inconvenient maintenance in the existing technology.

[0026] Example 2

[0027] Combination Figures 1-2 and Figure 4 As shown, the ultraviolet sterilization tank 5 and the regulating tank 6 are connected. The bottom of the regulating tank 6 is also provided with a regulating tank drain outlet 19. The ultraviolet sterilization tank 5 is equipped with an ultraviolet sterilization lamp group inside. The ultraviolet sterilization tank 5 is equipped with an ultraviolet cover inside. The bottom of the ultraviolet sterilization tank 5 is fixedly connected to a biochemical tank water level control pipe 20. A temperature-controlled water inlet 21 is fixedly connected to one side of the regulating tank 6. A breeding tank flow regulating valve 22 is fixedly connected to the inside of the regulating tank 6. The output end of the breeding tank flow regulating valve 22 is fixedly connected to a breeding tank water inlet 23. The breeding tank water inlet 23 is connected to the inside of the inner breeding tank 2. The input end of the breeding tank flow regulating valve 22 is provided with a temperature-controlled reflux inlet 24.

[0028] The technical solution described in the above-described embodiments of this application, during the application of this device, through the connection structure between the ultraviolet sterilization tank 5 and the regulating tank 6, the drain outlet 19 of the regulating tank, the ultraviolet sterilization lamp group, the ultraviolet cover, the water level control pipe 20 of the biochemical tank, the temperature control water inlet 21, the aquaculture tank flow regulating valve 22, the aquaculture tank water inlet 23, and the temperature control reflux inlet 24, enables the sterilization and purification, precise regulation, and recycling of water during use. During use, after preliminary... The treated water flows from the ultraviolet sterilization tank 5 into the connected regulating tank 6. The ultraviolet sterilization lamps inside the ultraviolet sterilization tank 5 sterilize the water, removing pathogenic microorganisms. An ultraviolet cover protects the lamps from direct water scouring and ensures proper equipment operation. The water level control pipe 20 at the bottom of the ultraviolet sterilization tank 5 allows for flexible adjustment of the water level in the biological tank 3, ensuring water level balance across all tanks. A temperature-controlled inlet is located on one side of the regulating tank 6. 21 can be connected to a water source with a suitable temperature. The water flow rate is adjusted by the internal aquaculture pond flow regulating valve 22. The treated water is transported to the inner aquaculture pond 2 through the aquaculture pond inlet 23. At the same time, the temperature control return port 24 at the input end of the aquaculture pond flow regulating valve 22 can realize the return flow regulation of the water, ensuring the stability of the water temperature and water volume in the inner aquaculture pond 2. When there is too much water or impurities in the regulating pond 6, the bottom regulating pond drain 19 can be discharged in time to avoid water stagnation affecting water quality. This design effectively improves the sterilization effect of the water through the synergistic effect of various structures, ensuring the hygiene and safety of the aquaculture water. At the same time, it realizes the precise control of water temperature and water volume, providing a suitable environment for the growth of giant freshwater prawns. The water circulation and reuse and convenient drainage settings also reduce water waste and manual cleaning workload, improve the convenience of use, and effectively improve the problems of incomplete water sterilization, difficult environmental control and low water resource utilization in the existing technology.

[0029] The working principle and advantages of this utility model are as follows: During the application of this device, the biological packing layer, aeration device, and water quality monitoring probe are fixedly installed in the biological tank 3 by bolts; the guide plate and water level sensor are fixedly installed in the buffer tank 4 by bolts; the water flow distributor, ultraviolet sterilization lamp group, quartz sleeve, and ultraviolet cover are fixedly installed in the ultraviolet sterilization tank 5 by bolts; the heating rod, refrigeration unit, pH adjustment agent dosing device, and stirring device are fixedly installed in the regulating tank 6 by bolts; the inclined tube packing and sludge collection hopper are fixedly installed in the sedimentation tank 7 by welding, and the sludge pump is fixedly installed by bolts; the filter tank 25 is connected to the filter element 17 by snap-fit; the seedling net cage is connected to the inner aquaculture tank 2 by snap-fit, and the aeration device is fixedly installed by bolts. The equipment includes an automatic feeding device, a water temperature sensor, and a dissolved oxygen sensor. An escape-prevention frame 12 is welded and fixed in place. A ring-shaped escape-prevention net 13 is attached to the escape-prevention frame 12 via snap-fit ​​connections. A reinforcing ring 15 is welded and fixed to the top of the outer tank 1, and a reinforcing bottom ring 16 is welded and fixed to the bottom of the inner aquaculture tank 2. During the application of this equipment, the above-mentioned structure is the conventional equipment used in existing aquaculture, and therefore will not be described in detail here. After the above structure is installed, the biological packing layer and aeration device can achieve biochemical purification of the water; the water quality monitoring probe and water level sensor can monitor water quality and water level data in real time; the guide plate and water flow distributor can stabilize the water flow; the ultraviolet sterilization lamp group, quartz sleeve, and ultraviolet cover can complete water sterilization; and the heating rod, refrigeration unit, and pH adjustment... The water quality parameters can be adjusted by the additive dosing device and the stirring device. The inclined tube packing, sludge hopper, sludge pump, and filter element 17 can achieve solid-liquid separation and impurity removal. The seedling cage, aeration device, and automatic feeding device ensure the breeding and aquaculture needs. The water temperature sensor and dissolved oxygen sensor monitor the aquaculture environment. The ring-shaped escape-proof net 13 and escape-proof frame 12 prevent shrimp from escaping. The reinforcing ring 15 and reinforcing bottom ring 16 improve the stability of the pond. Then, the breeding stage is prepared. By setting up the temperature control water inlet 21 of the regulating pond 6 to connect with the delivery pipeline and booster pump of the external clear water storage tank, the clear water can be stably injected into the system. After the clear water is injected, the heating rod and cooling unit inside the regulating pond 6 are started. With the feedback data from the water temperature sensor in the inner aquaculture pond 2, the water temperature is precisely adjusted. The water temperature is adjusted to the suitable range for giant freshwater prawn breeding. At the same time, pH regulator is added through the pH regulator dosing device in the regulating pond 6, and the stirring device is activated to ensure that the water quality parameters are evenly mixed. After the water quality is adjusted to meet the requirements, the water enters the inner breeding pond 2 through the breeding pond flow regulating valve 22 and the breeding pond inlet 23. The water level control pipe 14 of the breeding pond 7 is connected to the external main drainage pipe to regulate the water level of the inner breeding pond 2 to the required breeding height. Then, the giant freshwater prawn broodstock is placed in the seedling net cage inside the inner breeding pond 2, and the oxygenation device of the inner breeding pond 2 is turned on. This oxygenation device is connected to the oxygen supply pipe of the external oxygen generator to continuously ensure that the dissolved oxygen content of the water meets the standard. Finally, the breeding-specific feed is added at regular intervals through the automatic feeding device of the inner breeding pond 2.

[0030] During the breeding process, a water circulation treatment process is initiated simultaneously. Pollutants such as uneaten feed and feces generated in the inner breeding pond 2 are collected at the bottom center of the pond with the water flow. Initial solid-liquid separation is completed through the fish toilet 9. The sewage outlet of the fish toilet 9 is connected to the conveying pipe of the external sludge collection pond, so that the separated solid pollutants can be smoothly discharged to the sludge collection pond. The supernatant enters the sedimentation tank 7 through the three-way pipe 10. The three-way pipe 10 can realize the switching control of sewage discharge and normal drainage, without the need for manual transfer of pollutants. After entering the sedimentation tank 7, the inclined tube packing inside accelerates the sedimentation of suspended particles to the sludge collection hopper. The settled sludge is discharged through the sludge pump of the sedimentation tank 7. The sludge pump is connected to the feed pipe of the external sludge treatment equipment. The supernatant after sedimentation enters the filter tank 25. The filter element 17 inside the filter tank 25 removes fine suspended impurities, improves the water purity, and then enters the biological treatment tank 3. The interception effect of the filter element 17 can reduce the load of the subsequent biological treatment unit, thereby ensuring the water treatment efficiency.

[0031] After entering the biochemical purification stage, the biological packing layer inside biochemical tank 3 is covered with a large number of functional microorganisms such as nitrifying bacteria and denitrifying bacteria. The supporting aeration device is connected to the air supply pipeline of the external air compressor to continuously aerate the water to ensure the activity of microorganisms. When the water flows through the biological packing layer, the microorganisms degrade and transform toxic and harmful substances such as ammonia nitrogen and nitrite in the water. The water quality monitoring probe of biochemical tank 3 monitors various indicators of the treated water in real time to ensure that the purification effect meets the standards. The treated water enters buffer tank 4 through the output end of biochemical tank 3. The guide plate inside buffer tank 4 slows down the water flow speed to avoid water flow impact causing water quality fluctuations in subsequent treatment units. The water level sensor monitors the water level in the tank in real time. The biological drainage outlet 18 at the bottom of the buffer tank 4 is connected to the external emergency drainage pipe. If the water level in the tank is too high, the excess water can be discharged through this pipe. The water in the buffer tank 4 then enters the ultraviolet sterilization tank 5. The water flows evenly through the ultraviolet sterilization lamp group area through the water flow distributor. The ultraviolet rays emitted by the ultraviolet sterilization lamp group pass through the quartz sleeve to kill bacteria, viruses and other pathogenic microorganisms in the water. The ultraviolet cover prevents ultraviolet leakage to ensure operational safety. The sterilized water enters the regulating tank 6 again. If the water quality parameters fluctuate, the water temperature, pH value and other indicators can be adjusted again through the heating rod, refrigeration unit and pH adjustment agent dosing device of the regulating tank 6 to ensure that the water quality meets the growth requirements of giant freshwater prawns.

[0032] After the seedlings have reached a suitable size, the seedling net cages inside the inner culture tank 2 are removed, and the device is directly switched to the culture stage. At this time, the treated water is partially returned through the temperature-controlled return port 24 of the regulating tank 6. This temperature-controlled return port 24 is connected to the return pipe at the output end of the regulating tank 6. In conjunction with the culture tank flow regulating valve 22, the water flow rate entering the inner culture tank 2 is adjusted to achieve efficient water circulation and renewal. During the circulation process, the dissolved oxygen sensor and water temperature sensor of the inner culture tank 2 monitor water quality data in real time to ensure a stable culture environment. The annular escape-proof net 13 at the top of the inner culture tank 2 is fixed by the escape-proof frame 12, which can effectively prevent the giant freshwater prawns from escaping and avoid culture losses. The reinforcing ring 15 at the top of the outer tank 1 enhances the overall structural stability of the tank, and the reinforcing bottom ring 16 at the bottom of the inner culture tank 2 improves the load-bearing capacity of the tank, prevents the tank from deforming due to long-term water storage, and extends the service life of the device. During system operation, the device is periodically turned on. The sewage discharge device of the fish toilet 9 discharges the remaining solid pollutants. When the system needs to be fully drained, the channel from the three-way pipe 10 to the sedimentation tank 7 is closed, and the drain outlet 11 of the aquaculture tank is opened to discharge the water from the inner aquaculture tank 2 and each treatment tank to the external sewage treatment pipeline. This technical solution integrates breeding and aquaculture functions into one, eliminating the need for additional independent breeding facilities and seedling transfer, greatly simplifying the operation steps of breeding and aquaculture and reducing the complexity of aquaculture management. At the same time, through the automated water quality circulation treatment system, continuous purification and stable control of water quality are achieved, reducing frequent manual intervention and labor intensity. In addition, breeding and aquaculture are completed in the same tank, avoiding mechanical damage and environmental stress during seedling transfer, improving the seedling survival rate, reducing the probability of diseases in giant freshwater prawns, and comprehensively solving the problems of cumbersome inconvenience, large workload, and easy seedling mortality in the existing separate breeding and aquaculture model.

[0033] This technical solution uses an STM32F103RCT6 microcontroller, installed on the upper part of the outer wall of the regulating tank 6. The controller is equipped with an LCD1602 display screen. The main electronic components and their specifications are as follows: the ultraviolet sterilization lamp group uses a GPH1148T5L low-pressure mercury lamp with a power of 14W and a wavelength of 254nm; the aquaculture tank flow regulating valve 22 uses a ZCM-15 electromagnetic flow regulating valve with a working voltage of DC24V and a flow regulation range of 0.1-10m³ / h; the ultraviolet sterilization can be adjusted according to requirements. A UV intensity sensor (GS124 type, measurement range 0-100mW / cm²) is installed inside the bacterial culture tank 5 to monitor the working intensity of the UV sterilization lamp group. A temperature sensor (DS18B20 type, measurement range -55℃ to +125℃) and a liquid level sensor (YH-801 type, measurement range 0-5m) are installed inside the regulating tank 6 to monitor water temperature and liquid level, respectively. A flow sensor (LWGY-15 type, measurement range...) is installed at the water inlet 23 of the aquaculture tank. The system uses sensors with a flow rate of 0.01-0.6 m³ / h to provide feedback on the influent flow rate. These sensors can be selected and installed as needed to achieve automatic operation or assist manual operation. The power supply for the circuit system is as follows: AC220V mains power is converted to DC24V via a Mingwei S-100-24 switching power supply. The output of the switching power supply is connected to the controller, the UV sterilization lamp group, the electromagnetic flow regulating valve, and each optional sensor. The controller's I / O interface is connected to the drive module of the UV sterilization lamp group, the control terminal of the electromagnetic flow regulating valve, and the signal output terminals of each optional sensor. The controller receives sensor signals and outputs control commands to adjust the start and stop of the UV sterilization lamp group and the opening of the electromagnetic flow regulating valve, thereby achieving automatic control of water sterilization and flow regulation. During application, a 57BLDC brushless DC motor is added to drive the water pump and other motor equipment. The motor is equipped with an incremental encoder, which can flexibly adjust the rotation and stepless speed regulation. The motor driver is connected to the controller's I / O interface, and the controller outputs a PWM signal to control the motor speed.

[0034] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0035] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
