Description

Technical Field

[0001] The invention belongs to the technical field of crayfish breeding, in particular to a breeding box for raising crayfish seedlings. Background Art

[0002] Crayfish seedling technology is of great significance in the field of aquaculture. Traditional seedling breeding methods often have many challenges, such as improper isolation of broodstock and larvae, which leads to larvae being eaten by broodstock, poor water quality management affecting the survival rate of larvae, and cumbersome and high loss of larvae during the collection process. Therefore, it is particularly important to develop an efficient and practical crayfish seedling breeding device.

[0003] Traditional crayfish seedling breeding devices usually include a box body, a box cover, a breeding chamber and a breeding chamber. The design and use of the breeding box are of great significance for improving the survival rate of shrimp larvae and reducing the cost of breeding. The breeding chamber is usually designed to provide suitable environmental conditions such as water quality, temperature, and light to meet the breeding needs of crayfish parents and the growth needs of shrimp larvae. The breeding chamber is used to isolate parent shrimps and shrimp larvae. During the seedling breeding process, in order to ensure water quality and increase dissolved oxygen, the water in the breeding chamber is usually aerated. However, if the aeration device is improperly set up or operated improperly, during the water exchange process between the breeding chamber and the breeding chamber, the shrimp larvae may be washed back into the breeding box by the water flow. This will not only increase the difficulty of managing shrimp larvae, but may also cause damage to the shrimp larvae and reduce the survival rate.

[0004] In summary, the fact that the shrimp larvae in the nursery chamber will flow back to the breeding box during the aeration process has become a problem that needs to be solved urgently by technicians in this field. Therefore, it is necessary to propose a breeding box for crayfish nursery that can effectively isolate the broodstock and shrimp larvae. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a breeding box for crayfish seedlings, which effectively prevents the shrimps in the breeding chamber from flowing back into the breeding chamber during the aeration process through the synergistic effect of a floating plate, a fixed plate, a hollow net bag and an air bag.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a breeding box for raising crayfish seedlings, comprising a box body, a box cover, a breeding chamber and a breeding chamber, the box cover is rotatably connected to the top of the box body, an inner wall of the box body is provided with a control component for regulating the operation of a device, a breeding chamber and a breeding chamber are sequentially provided in the box body along the box cover to the bottom of the box body, a fixed plate is fixedly connected to the inner wall of the box body between the breeding chamber and the breeding chamber, a floating plate is provided on the top of the fixed plate, a slider is fixedly connected to the outer wall of the floating plate, a slide groove is provided on the inner wall of the box body at the top of the fixed plate, the slider slides in cooperation with the slide groove, and the slider An air bag is fixedly connected to the upper part, a plurality of alignment holes are opened on the fixed plate, a plurality of through holes corresponding to the alignment holes are opened on the floating plate, the part of the through hole extending into the alignment hole is fixedly connected with a cylindrical support plate, the inner side walls of the alignment holes are fixedly connected with a hollow alignment plate, the shape of the cylindrical support plate is the same as the hollow part of the edge of the alignment plate, the bottom wall of the hollow part of the bottom edge of the alignment plate is fixedly connected with a hollow net bag for being fitted and stretched with the circular support plate and the cylindrical support plate, and the bottom wall of the box body is fixedly connected with an aeration component for increasing the dissolved oxygen in the water and controlling whether the air bag is inflated, and a purification component for purifying the water quality.

[0007] The following principles and beneficial effects are achieved by adopting the above scheme:

[0008] Basic principle: Through the combination of the floating plate and the air bag, the floating plate slides on the fixed plate through the slider and the slide groove. When the air bag is not inflated, the floating plate descends and drives the cylindrical support plate and the hollow net bag to be spread out, and the through hole is connected with the seedling cavity to form an effective shrimp fry passage. When the air bag is inflated, the floating plate rises and drives the cylindrical support plate. The hollow net bag without the support of the cylindrical support plate spreads out to prevent the shrimp fry from being directly rushed back to the breeding cavity from the seedling cavity.

[0009] Beneficial effects:

[0010] 1. The present invention controls the lifting and lowering of the floating plate by inflating and deflating the air bag, thereby adjusting the fitting state of the cylindrical support plate and the hollow net bag, effectively preventing the shrimp larvae in the nursery cavity from being washed back into the breeding cavity by water flow during the aeration process, and reducing the difficulty and loss of shrimp larvae management.

[0011] 2. The design of the present invention ensures that the water exchange between the breeding chamber and the nursery chamber is safer and more controllable, avoiding the damage of the shrimp larvae caused by backflow, thereby improving the survival rate of the shrimp larvae.

[0012] 3. The present invention combines the regulating function of the control component to realize intelligent control of aeration components, purification components and other equipment, and automatically adjusts according to changes in environmental parameters such as water quality and dissolved oxygen, providing a more stable and suitable growth environment for crayfish seedlings.

[0013] Furthermore, the control component includes a controller and a battery. The controller is fixedly connected to the top of the box, and the battery is fixedly connected to the inner wall of the box below the controller. The aeration component, the purification component and the battery are connected to the controller signal.

[0014] Beneficial effects: As an important component of the control component, the battery provides a stable power supply for the controller, aeration component, purification component, etc. Even in the event of an external power outage, the battery can ensure that the various devices in the breeding box continue to operate for a period of time, thereby ensuring the continuity and stability of the breeding environment.

[0015] Furthermore, the aeration assembly includes a pump assembly, which is fixedly connected to the inner wall of the box below the battery. An aeration base is fixedly connected to the bottom of the seedling cavity. The air bag and the aeration base are both connected to the pump assembly, and the pump assembly is connected to the controller signal.

[0016] Beneficial effects: As the core component of the aeration assembly, the pump assembly can automatically adjust the aeration intensity and frequency according to changes in environmental parameters such as water quality and dissolved oxygen through signal connection with the controller. This precise control not only helps to maintain the stability of water quality in the nursery chamber, but also avoids the adverse effects on shrimp larvae caused by excessive aeration.

[0017] Furthermore, the purification component includes a water purifier, which is detachably connected to one side of the inner bottom of the seedling chamber. A water outlet is opened at the bottom of the outer wall of the box body. The water purifier is connected to the water outlet and is connected to the controller signal.

[0018] Beneficial effects: The water purifier is fixedly connected to the bottom of the nursery chamber, which can effectively remove suspended matter, organic matter, heavy metals and other impurities in the water, and improve the clarity and purity of the water. Through the intelligent control of the water purifier by the controller, the purification intensity and frequency can be automatically adjusted according to the water quality monitoring results to ensure that the water in the nursery chamber is always in a state suitable for the growth of crayfish.

[0019] Furthermore, a plurality of heating wires are fixedly connected to the inner walls of the breeding chamber and the seedling raising chamber, and the heating wires are all connected to the controller signal.

[0020] Beneficial effect: The heating wire is connected to the controller's signal, allowing the breeder to accurately adjust the temperature in the breeding chamber and the nursery chamber through the controller. This precise temperature control helps maintain the optimal temperature range required for crayfish growth and improves its growth rate and survival rate.

[0021] Furthermore, a plurality of water quality probes are fixedly connected to the inner walls of the breeding chamber and the seedling raising chamber, and the water quality probes are all connected to the controller signal.

[0022] Beneficial effects: The water quality probe is fixedly connected to the inner wall of the breeding chamber and the nursery chamber, and can monitor key water quality parameters such as dissolved oxygen, pH value, temperature, turbidity, etc. in real time. By connecting with the controller signal, the water quality probe can transmit the monitoring data to the controller in real time, providing accurate and timely water quality information for the breeders.

[0023] Furthermore, a plurality of dissolved oxygen probes are fixedly connected to the inner walls of the breeding chamber and the seedling raising chamber, and the dissolved oxygen probes are all connected to the controller signal.

[0024] Beneficial effects: The dissolved oxygen probe is fixedly connected to the inner wall of the breeding chamber and the nursery chamber, which can monitor the dissolved oxygen content in the water in real time to ensure that the crayfish is in a suitable dissolved oxygen environment. Accurate dissolved oxygen monitoring helps to detect insufficient or excessive dissolved oxygen in time, thereby avoiding adverse effects on the growth and development of crayfish.

[0025] Furthermore, a lighting lamp for adjusting the light intensity in the breeding cavity and the seedling raising cavity is fixedly connected to the bottom of the box cover, and the lighting lamp is connected to the controller signal.

[0026] Beneficial effects: The controller can accurately adjust the light intensity of the lighting lamp to meet the light needs of crayfish at different growth stages. This helps promote the normal growth and reproduction of crayfish and improve their survival rate and growth rate.

[0027] Furthermore, cameras for monitoring the activities of shrimp larvae are fixedly connected to the inner walls of the breeding chamber and the seedling chamber.

[0028] Beneficial effects: The camera can capture and transmit the activities of the shrimp in the nursery chamber in real time, so that the farmers can intuitively understand the growth status, behavioral habits and whether there are any abnormalities of the shrimp. This helps to timely discover and deal with problems that may affect the growth of shrimp, such as disease, hunger or environmental discomfort.

[0029] Furthermore, the through hole has a diameter of 2 cm.

[0030] Beneficial effect: The through hole design with a diameter of 2 cm can allow sufficient water flow to pass through to keep the water quality in the nursery cavity fresh, and can also allow the shrimp larvae to escape from the parent shrimp through the through hole, ensuring that the shrimp larvae grow in a safe environment.

DETAILED DESCRIPTION

[0037] The following is further described in detail through specific implementation methods:

[0038] Example 1

[0039] Basically as attached Figure 1-Figure 5 As shown: a breeding box for crayfish seedlings, including a box body 4, a box cover 2, a breeding chamber 5 and a breeding chamber 14, an inner wall of the box body 4 is provided with a control component for regulating the operation of the device, the control component includes a controller 1 and a battery 18, one side of the box cover 2 is hinged to the top of the box body 4, and the bottom of the box cover 2 is fixedly connected by screws with a lighting lamp 7 for adjusting the light intensity in the breeding chamber 5 and the breeding chamber 14, and the lighting lamp 7 is connected to the controller 1 by signal. The controller 1 is fixedly connected to the top of the box body 4 by screws, and the battery 18 is fixedly connected to the inner wall of the box body 4 below the controller 1 by bolts, and the battery 18 is connected to the controller 1 by signal. The battery 18 adopts a high-performance lithium-ion battery. During the operation of the breeding box, the battery can be charged by an external power supply at the same time, and maintain a stable power supply for the controller 1, the aeration component, the purification component and the lighting lamp 7. In the case of a sudden interruption of the external power supply, the battery 18 can be immediately switched to a backup power supply to provide necessary power support for the breeding box and continue to operate for a period of time. This period allows farmers to take necessary measures to protect the safety of broodstock and postlarvae and avoid farming risks caused by sudden power outages.

[0040] Inside the box body 4, a breeding chamber 5 and a seedling raising chamber 14 are sequentially arranged along the box cover 2 toward the bottom of the box body 4. A fixing plate 17 is fixedly connected to the inner wall of the box body 4 between the breeding chamber 5 and the seedling raising chamber 14 by screws. A floating plate 10 is arranged on the top of the fixing plate 17. A slider 21 is integrally formed on the outer wall of the floating plate 10. A slide groove 19 is provided on the inner wall of the box body 4 at the top of the fixing plate 17. The slider 21 slides in cooperation with the slide groove 19. An air bag 20 is fixedly connected to the slider 21. A plurality of alignment holes 24 are provided on the fixing plate 17. A plurality of through holes 6 corresponding to the alignment holes 24 are provided on the floating plate 10. The diameter of the through hole 6 is 2 cm. A cylindrical support plate 23 is integrally formed on the part of the hole extending into the alignment hole 24. A hollow alignment plate 25 is fixedly connected to the inner wall of the alignment hole 24. Figure 5 As shown, the shape of the cylindrical support plate 23 is the same as the hollow portion of the edge of the alignment plate 25, and the bottom wall of the hollow portion of the bottom edge of the alignment plate 25 is fixedly connected with a hollow net bag 22 for being fitted and stretched with the cylindrical support plate 23, and the bottom wall of the box body 4 is provided with an aeration component for increasing the dissolved oxygen in the water and controlling whether the air bag 20 is inflated, and a purification component for purifying the water quality.

[0041] The aeration assembly includes a pump assembly 15, which is an air pump for sucking external air. The pump assembly 15 is fixedly connected to the inner wall of the box body 4 below the battery 18. The bottom of the seedling chamber 14 is fixedly connected to the aeration base 13 by screws. The air bag 20 and the aeration base 13 are both connected to the pump assembly 15. The pump assembly 15 is connected to the controller 1 by signal. The purification assembly includes a water purifier 12. The water purifier 12 is detachably connected to one side of the inner bottom of the seedling chamber 14. The bottom of the outer wall of the box body 4 is provided with a water inlet 3. The water purifier 12 is connected to the water inlet 3. The water purifier 12 is connected to the controller 1 by signal.

[0042] Specific implementation steps: First, set the operating parameters of the aeration component and the purification component, such as the aeration frequency and the purification cycle, through the controller 1. Make sure that the controller 1 is correctly connected and controls the battery 18, the aeration component and the purification component. Open the box cover 2, add the prepared broodstock into the breeding chamber 5, ensure that the number is appropriate to avoid overcrowding, and then close the box cover 2. After closing the box cover 2, a relatively closed and safe breeding environment is formed inside the breeding box, which helps to reduce external interference and disease transmission. After breeding for a period of time, shrimp fry are obtained. When the shrimp fry reaches a certain growth stage, the shrimp fry are automatically transferred from the breeding chamber 5 to the nursery chamber 14 through the through hole 6 on the floating plate 10. Not only does it save the cost of manual transfer, but it also avoids damage to the shrimp fry caused by improper operation.

[0043] The pump assembly 15 is started by the controller 1 to start working, and the air bag 20 and the aeration base 13 are inflated. The bubbles released by the aeration base 13 can increase the dissolved oxygen content in the water, providing sufficient oxygen for the parent shrimps and shrimp larvae. As the inflation volume of the air bag 20 gradually increases, the air bag 20 will continue to expand and rise. The air bag 20 drives the floating plate 10 to rise together through the sliding cooperation of the slider 21 and the slide groove 19. In this process, the through hole 6 on the floating plate 10 and the cylindrical support plate 23 inside it gradually move away from the alignment hole 24 and the hollow net bag 22 on the fixed plate 17, thereby closing the passage for the shrimp larvae to transfer from the breeding chamber 5 to the seedling chamber 14. This is because when the floating plate 10 rises, the cylindrical support plate 23 no longer opens the hollow net bag 22 below the alignment plate 25 in the alignment hole 24, so that the hollow net bag 22 floats freely and blocks the through hole 6, and its opening is in an unsupported state, making it difficult for the shrimp to enter the breeding chamber 5 through its opening, so that the shrimp cannot be transferred to the breeding box through the through hole 6. The shrimp are effectively prevented from being blown back to the breeding chamber 5 by the strong airflow during the aeration process, ensuring the smooth transfer and growth of the shrimp.

[0044] When the aeration assembly stops working, the gas in the air bag 20 squeezes into the pump assembly 15 under the action of the underwater pressure and is released through the aeration base 13. When the air bag 20 gradually deflates and descends, the floating plate 10 will also descend. At this time, the through hole 6 on the floating plate 10 and its cylindrical support plate 23 gradually approach and insert into the hollow net bag 22 below the alignment plate 25 in the alignment hole 24, and the hollow net bag 22 is opened, thereby opening the transfer channel for the shrimp larvae. The shrimp larvae can use these channels formed by the hollow net bags 22 to automatically and safely transfer from the breeding chamber 5 to the nursery chamber 14. Not only is the transfer efficiency of the shrimp larvae improved, but also the safety during the transfer process is ensured.

[0045] The user regularly checks the water quality and adjusts the parameters of the lighting lamp 7. The water quality is purified by the water purifier 12 to ensure that the water is clean and pollution-free. According to the water quality monitoring results, the operating parameters of the purification component are adjusted through the controller 1, such as increasing the purification frequency or extending the purification time. The box cover 2 is opened regularly to observe the growth of the parent shrimp and shrimp, including changes in body shape, activity, etc. If any abnormality is found, such as slow growth, decreased vitality, etc., the water quality, feed and other conditions are checked in time, and corresponding adjustments are made.

[0046] In the nursery chamber 14, the shrimp will continue to grow until they reach the market standard. Clean and maintain the breeding box regularly, including cleaning residual feed, changing water quality, etc. Check the working status of the controller 1, battery 18, aeration component and purification component regularly to ensure their normal operation. When the shrimp reaches the preset growth standard, open and disassemble the water purifier 12 through the water inlet 3 and remove the crayfish from the nursery chamber 14.

[0047] Example 2

[0048] Basically as attached Figure 2 As shown: The difference from the above embodiment is that a plurality of heating wires 8 are embedded on the inner walls of the propagation chamber 5 and the seedling chamber 14, and the heating wires 8 are all connected to the controller 1 by signal.

[0049] Specific implementation steps: Based on Example 1, the controller 1 automatically adjusts the working state of the heating wire 8 according to the preset heating temperature to keep the water temperature in the breeding chamber 5 and the seedling chamber 14 within a suitable range. This helps the crayfish grow and reproduce under suitable temperature conditions, and improves the breeding efficiency and survival rate.

[0050] Example 3

[0051] Basically as attached Figure 2 and Figure 4 As shown: The difference from the above embodiment is that a plurality of water quality probes 9 are fixedly connected to the inner walls of the breeding chamber 5 and the seedling chamber 14 by screws, and a plurality of dissolved oxygen probes 11 are fixedly connected to the inner walls of the breeding chamber 5 and the seedling chamber 14 by screws, and both the water quality probe 9 and the oxygen probe are connected to the controller 1 signal.

[0052] Specific implementation steps: Based on Example 1, the controller 1 uploads the real-time collected water quality and dissolved oxygen data to the display screen or remote monitoring system for the breeder to view and analyze at any time. According to the data monitoring results, the breeder can timely discover abnormal changes in water quality and dissolved oxygen, and take corresponding treatment measures, such as increasing the aeration frequency, extending the purification time, etc.

[0053] Example 4

[0054] Basically as attached Figure 2 and Figure 4 As shown: The difference from the above embodiment is that the inner walls of the breeding chamber 5 and the nursery chamber 14 are fixedly connected with a camera 16 for monitoring the activities of the shrimp larvae by screws.

[0055] Specific implementation steps: Based on Example 1, the camera 16 will monitor the activity of the shrimp in real time and transmit the picture to the controller 1 or the remote monitoring system. The real-time picture taken by the camera 16 is viewed through the controller 1 or the remote monitoring system to observe the growth status, activity pattern and abnormal behavior of the shrimp. According to the monitoring results, the breeding environment is adjusted in time, such as increasing the aeration frequency, adjusting the water temperature, etc., to ensure the healthy growth of the shrimp.

[0056] The video footage shot by the camera 16 is replayed and analyzed regularly to understand the growth trend of the shrimp larvae and possible problems.
