Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and more specifically, to an adjustable-light aquaculture seedling box. Background Technology

[0002] In aquaculture seedling cultivation, light conditions are crucial for seedling growth and development. Different aquatic seedlings (such as loach, shrimp, and crab) have varying requirements for light intensity and duration. Appropriate light not only promotes seedling metabolism and enhances their appetite and digestive capacity, but also optimizes seedling distribution in the water, promotes the growth of beneficial algae to maintain water quality stability, and rational light regulation helps improve seedling survival rate and seedling health. However, existing aquaculture seedling cultivation devices generally suffer from insufficient flexibility in light regulation, making it difficult to precisely control light according to the needs of different seedling growth stages. Furthermore, most devices do not effectively coordinate with key functions such as water flow and dissolved oxygen maintenance. This often leads to seedling growth and development being affected by unsuitable light or imbalances in the water environment (such as uneven dissolved oxygen or water temperature differences), reducing seedling quality and efficiency. Therefore, there is an urgent need to develop an aquaculture seedling cultivation device that can flexibly adjust light and improve the water environment.

[0003] Chinese patent CN221615988U discloses a loach breeding and raising device. This device uses a shading net to provide shade for the loach breeding boxes, which to some extent meets the light regulation needs of loach breeding and increases ease of use. However, in practical application, the device has revealed many defects. Because the water flow inside the box is stagnant, dissolved oxygen cannot be evenly distributed, and a low-oxygen zone will form at the bottom of the box. In high-density breeding, the larvae are easily suffocated due to lack of oxygen. The lack of water flow stimulation will affect the muscle development and swimming ability of the larvae, reduce their physical condition, and hinder healthy growth. In addition, the stagnant water environment is not conducive to the even distribution of beneficial microorganisms and algae, which will disrupt the ecological balance of the water and cause local temperature differences in the water inside the box, increasing the risk of stress to the larvae. Ultimately, this will lead to a significant decrease in the survival rate of the larvae and serious damage to the quality of the larvae. It is evident that the existing aquaculture breeding and raising device has obvious defects and deficiencies and urgently needs to be improved and optimized to improve the quality and efficiency of aquatic animal breeding.

[0016] 3. Beneficial Effects Compared with the prior art, the advantages of this invention are: First, this device, driven by an electric push rod and a first motor, enables the vertical lifting and horizontal displacement of the light-emitting components. It not only allows for the adjustment of light position, intensity, and duration as needed, simulating natural light rhythms to promote seedling metabolism and enhance appetite and digestion, but also automatically opens and closes the top cover for convenient and quick removal and placement of the seedling filter box. During seedling cultivation, it allows for precise control of light conditions according to different growth stages, optimizing seedling distribution and preventing oxygen deficiency or compression due to excessive phototaxis. When seedlings need to be separated, simply operate the motor to remove the top cover for easy removal of the seedling filter box, significantly improving management efficiency and effectively increasing seedling survival rate and seedling health. Secondly, this device employs a coordinated oxygen supply component and a reflux mechanism. During use, the oxygen supply pump evenly releases microbubbles into the water through the supply pipe and annular pipe, increasing the dissolved oxygen content. Simultaneously, the second motor drives a bevel gear to circulate the water in the reflux pipe, ensuring even distribution of dissolved oxygen within the tank. This effectively solves the problem of low oxygen at the bottom of the tank, reducing the risk of seedlings suffocating due to lack of oxygen. The water circulation also helps move the seedlings, preventing localized accumulation and promoting swimming and exercise, thus improving their activity and physical condition. Furthermore, the circulating water can suspend and discharge metabolic waste, preventing waste decomposition from consuming dissolved oxygen and releasing toxic substances, maintaining water quality stability, and reducing the stimulation and toxicity of water quality deterioration on seedlings, creating a favorable aquatic environment for seedling growth. Third, this device uses heating wires in the heating assembly to heat the water in the return pipe. A temperature sensor monitors the water temperature in real time and feeds it back to the controller, automatically adjusting the heating wire power to maintain a constant water temperature inside the chamber. This eliminates localized temperature differences caused by stagnant water flow, reduces stress on seedlings due to temperature changes, and ensures suitable growth temperatures for seedlings in various environments. The base and support frame provide stable support, ensuring stable operation of the seedling chamber. The seedling filter box facilitates the separation of seedlings from the water, making it easy to clean waste and observe growth. The ventilation window, combined with the protective net, ensures air circulation within the chamber while preventing external debris from entering, comprehensively improving the safety and controllability of the seedling environment.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example: Please see Figures 1-8An adjustable light-controlled aquaculture seedling box includes a base 1, a box body 2 fixedly installed on the top of the base 1, a reflux mechanism 3 fixedly installed on the outside of the box body 2, a light-controlled mechanism 5 fixedly installed on the upper back of the base 1, a controller 4 fixedly installed on the upper front of the box body 2, a touch screen on the front of the controller 4, a seedling filter box 6 placed inside the box body 2, the bottom of the light-controlled mechanism 5 extending into the inside of the box body 2, and a support frame 9 fixedly installed on the outer bottom of the base 1. The lighting mechanism 5 includes a side arm 51, which is fixedly installed at the middle of the rear top of the base 1. An electric push rod 52 is fixedly installed at the top of the side arm 51. A displacement component 53 is fixedly installed through the output end of the electric push rod 52, and a lighting component 54 is fixedly installed at the front end of the displacement component 53. An oxygen supply component 55 is fixedly installed in the middle of the lighting component 54, and the bottom of the oxygen supply component 55 is inserted into the interior of the box 2. In this adjustable lighting aquaculture seedling box, the various mechanisms work together to achieve specific functions. The base 1 and support frame 9 provide stable support. The box 2 is used to accommodate seedlings and water. When the lighting needs to be adjusted, the controller 4 receives the operation command via the touch screen, activates the lighting mechanism 5, and the electric push rod 52 extends and retracts, driving the displacement component 53 to rise and fall vertically. The first motor 534 drives the lead screw 532 to rotate. Through the threaded engagement between the lead screw 532 and the slider 533, the slider 533 slides horizontally within the guide rail 531, thereby driving the lighting component 54 to move horizontally. This allows for flexible adjustment of the lighting position and range. The brightness control module in the lighting component 54 can adjust the intensity and duration of the light lamp 544 as needed to meet the lighting requirements of seedlings at different growth stages. During this process, the oxygen supply component 55 works simultaneously. The oxygen pump 552 inputs air into the air supply pipe 551, and through the oxygen supply holes 554 on the annular pipe 553, it evenly releases tiny bubbles into the water in the tank 2 to increase the dissolved oxygen content of the water and ensure the oxygen supply required for seedling growth. The seedling filter box 6 can separate the seedlings from the water, facilitating daily cleaning and management.

[0023] Please see Figures 1-5A drainage hopper 7 is fixedly installed in the middle of the bottom of the base 1, and a drainage valve 8 is fixedly installed at the bottom of the drainage hopper 7. The input end of the drainage hopper 7 is connected to the bottom of the box 2. During the operation of this adjustable light aquaculture seedling box, impurities and waste will gradually accumulate in the water in the box 2 due to seedling metabolism, feed residue and other factors. When it is necessary to replace the water or clean the impurities deposited at the bottom of the box, the operator issues a command through the controller 4 or operates manually to open the drainage valve 8. Since the input end of the drainage hopper 7 is connected to the bottom of the box 2, under the action of gravity, the water in the box 2, together with the suspended feces, uneaten feed and other metabolic waste, will flow along the slope of the bottom of the box 2 or the natural flow trend to the drainage hopper 7, and finally be discharged from the box 2 through the drainage valve 8. This process realizes the renewal of the water in the box 2 and the cleaning of waste, ensuring the cleanliness of the water in the box 2, providing a good water environment for the healthy growth of seedlings, and also facilitating the daily maintenance and management of the seedling box by the aquaculture personnel.

[0024] Please see Figures 1-4 and Figures 7-8The displacement component 53 includes a guide rail 531, which is fixedly mounted on the bottom output end of the electric push rod 52. A lead screw 532 is rotatably connected inside the guide rail 531, and a slider 533 is threadedly connected to the outer surface of the lead screw 532. The slider 533 is slidably connected inside the guide rail 531. A lighting component 54 is fixedly mounted on the front of the slider 533. A first motor 534 is fixedly mounted on one end of the guide rail 531. The output end of the first motor 534 passes through the guide rail 531 and connects to the end of the lead screw 532. The lighting component 54 includes a connecting arm 541, which is fixedly mounted on the slider 533. On the front, a top cover 542 is fixedly installed at the front end of the connecting arm 541. A supplementary lighting cover 543 is fixedly installed on the top of the top cover 542. Light lamps 544 are fixedly installed in a ring at equal intervals inside the supplementary lighting cover 543. The controller 4 also has a brightness control module inside. The oxygen supply component 55 includes an air supply pipe 551, which is fixedly installed in the middle of the inner side of the supplementary lighting cover 543. An oxygen pump 552 is fixedly installed at the input end of the air supply pipe 551. A ring-shaped pipe 553 is fixedly installed through the supplementary lighting cover 543 at the bottom of the air supply pipe 551. An air supply pump is installed in a ring at equal intervals at the top of the ring-shaped pipe 553. Oxygen pore 554. In this aquaculture seedling box, when it is necessary to adjust the position and intensity of the light, the controller 4 receives the operation command through the touch screen and starts the first motor 534. The output end of the first motor 534 drives the lead screw 532 to rotate. Since the lead screw 532 is threadedly connected to the slider 533 and the slider 533 slides in the guide rail 531, the rotation of the lead screw 532 causes the slider 533 to move horizontally along the guide rail 531, thereby driving the light assembly 54 fixed on the front of the slider 533 to move horizontally. In the light assembly 54, the connecting arm 541 moves with the slider 533, driving the top cover 542 and the supplementary light cover 5. 43. Cover or remove the top of the box 2. Under the control of the brightness control module, the light intensity and duration of the light lamp 544 in the supplementary light cover 543 can be adjusted as needed to meet the light requirements of the seedlings at different growth stages. At the same time, the oxygen pump 552 is started, and air is input into the air supply pipe 551 fixed in the middle of the inner side of the supplementary light cover 543. The air is evenly released into the water in the box 2 through the annular pipe 553 at the bottom of the air supply pipe 551 and the oxygen supply holes 554 arranged at equal intervals at the top, increasing the dissolved oxygen in the water and providing sufficient oxygen for the growth of the seedlings. The whole process realizes the coordinated operation of light regulation and oxygenation functions.

[0025] Please see Figures 1-6The reflux mechanism 3 includes a reflux pipe 31, a drive assembly 32, and a heating assembly 33. The reflux pipes 31 are arranged in a ring at equal intervals and fixedly installed on the outer surface of the housing 2. A rotating shaft 34 is rotatably connected inside the reflux pipe 31. The outer end of the rotating shaft 34 passes through the reflux pipe 31 and is fixedly installed with a bevel gear 36. The bevel gears 36 that are close to each other are meshed with each other. The drive assembly 32 is fixedly installed at one rear end of the base 1. The heating assembly 33 is located outside the reflux pipe 31. The input and output ends of the reflux pipe 31 are respectively connected to the corresponding positions inside the housing 2. The two sides are connected, and a conveying auger 37 is fixedly installed on the outer surface of the rotating shaft 34. The drive assembly 32 includes a connecting rod 321, which is fixedly installed on one end of the rear side of the base 1. A bracket 322 is fixedly installed on the outer end of the connecting rod 321, and an installation sleeve 323 is fixedly installed on the top of the bracket 322. A second motor 324 is fixedly installed on the inner side of the installation sleeve 323. The output end of the second motor 324 is fixedly connected to the outer side of a bevel gear 36. When this aquaculture seedling box is running, the reflux mechanism 3 works in concert through the drive assembly 32, the reflux pipe 31, and the heating assembly 33. When the second motor 324 is started, its output end drives the bevel gear 36 fixedly connected to it to rotate. Since the bevel gears 36 that are close to each other mesh with each other, the bevel gear 36 will drive the other bevel gears 36 to rotate synchronously, thereby causing the rotating shaft 34 to rotate in the return pipe 31. The conveying auger 37 fixed on the outer surface of the rotating shaft 34 will rotate accordingly, generating a pumping effect. The input end of the return pipe 31 draws water from one side of the tank 2. Under the action of the conveying auger 37, the water flows in the return pipe 31 and is sent back to the other side of the tank 2 from the output end, forming the water inside the tank 2. The circulating water helps the seedlings move, preventing localized clustering and promoting their exercise. It also helps to suspend and expel metabolic waste. During this process, the heating element 332 of the heating component 33 generates heat to heat the water in the return pipe 31. The outer casing 331 is made of heat-insulating material to reduce heat loss. The temperature sensor 333 monitors the water temperature in the tank 2 in real time and feeds the data back to the controller 4. The controller 4 adjusts the power of the heating element 332 according to the set temperature value to achieve precise control of the water temperature in the tank 2, ensuring a constant water temperature and creating a stable temperature environment for seedling growth.

[0026] Please see Figures 7-8The heating component 33 includes an outer sleeve 331, which is fixedly installed on the outer surface of the return pipe 31. The outer sleeve 331 is made of heat-insulating material, and an electric heating wire 332 is fixedly installed on the inner side of the outer sleeve 331. The inner side of the electric heating wire 332 is in close contact with the outer surface of the return pipe 31. The heating component 33 also includes a temperature sensor 333, which is fixedly installed on the lower side of the air supply pipe 551 inside the box 2. A ventilation window 10 is opened at the upper back of the box 2, and a protective net 11 is fixedly connected inside the ventilation window 10. During the operation of this aquaculture seedling box, the heating component 33 and the ventilation window 10 work together to ensure the stability of the environment inside the box. The temperature sensor 333 monitors the water temperature on the lower side of the air supply pipe 551 inside the box 2 in real time and transmits the data to the controller 4. When the water temperature is detected to be lower than the set value, the controller 4 controls the heating wire 332 to be energized. Since the inner side of the heating wire 332 is in contact with the outer surface of the return pipe 31, the heat generated directly heats the water circulating in the return pipe 31. The heated water flows back into the tank 2, thereby raising the water temperature inside the tank. The outer tube 331 is made of heat-insulating material, which can effectively reduce heat loss, improve heating efficiency and maintain stable water temperature. At the same time, the ventilation window 10 opened at the upper back of the tank 2 has an internal protective net 11 that can block the entry of external debris. The ventilation window 10 ensures the air circulation between the tank and the outside. On the one hand, it avoids abnormal air pressure caused by water circulation, oxygenation and other operations inside the tank. On the other hand, it ensures fresh air inside the tank, creates a good gas environment for the seedlings, and further ensures the healthy growth of the seedlings.

[0027] The operating principle and advantages of this invention are as follows: During overall operation, the base 1 provides stable support for the entire seedling box, the support frame 9 enhances the contact stability between the bottom of the base 1 and the ground, the box 2 is used to hold aquatic animal seedlings, and if it is necessary to separate the seedlings during use, they can be filtered out of the water through the seedling filter box 6 for easy cleaning and management. The controller 4 receives operation commands through the touch screen and controls the operation of each component. During use, when the lighting mechanism 5 is running, the electric push rod 52 can drive the displacement component 53 to rise and fall vertically, adjusting the height of the lighting component 54. During height adjustment, the first motor 534 can also drive the lead screw 532 to rotate, and the threaded engagement between the lead screw 532 and the slider 533 causes the slider 533 to move on the guide rail 531. The inner horizontal sliding causes the lighting component 54 to move horizontally, causing the top cover 542 to cover the top of the box 2. At this time, the lighting lamp 544 in the supplementary lighting cover 543 can adjust the light intensity and duration as needed under the action of the brightness control module to meet the light needs of different growth stages of aquatic animal seedlings. At the same time, the oxygen pump 552 inputs air into the air supply pipe 551, and releases tiny bubbles evenly into the water in the box 2 through the oxygen supply hole 554 on the annular pipe 553 to increase the dissolved oxygen in the water. When it is necessary to remove the seedlings, simply start the first motor 534 to drive the lead screw 532 to move the supplementary lighting cover 543 and the top cover 542 from the top of the box 2. At this time, the seedling filter box 6 can be removed from the inside of the box 2, and the seedlings can be quickly filtered and removed. During the cultivation process, the reflux mechanism 3 can be activated. When the reflux mechanism 3 is working, the second motor 324 drives the bevel gear 36 to rotate. The meshing bevel gear 36 drives the rotating shaft 34 and the conveying auger 37 on its outer surface to rotate inside the reflux pipe 31, causing the water in the reflux pipe 31 to flow. The input end of the reflux pipe 31 draws in water from one side of the tank 2, and after circulating through the reflux pipe 31, it is sent back to the other side of the tank 2 from the output end. The meshing transmission between each rotating shaft 34 through the bevel gear 36 can synchronously drive the conveying rotation inside each reflux pipe 31. Through the rotation of the conveying auger 37 inside each reflux pipe 31, the water inside the water tank can be pumped and pumped to form the tank. The water inside the tank 2 circulates. In the heating component 33, the heating wire 332 generates heat when energized, which heats the water in the return pipe 31. The insulation material of the outer casing 331 reduces heat loss. The temperature sensor 333 monitors the water temperature inside the tank 2 in real time and feeds the data back to the controller 4. The controller 4 adjusts the power of the heating wire 332 according to the set temperature value to keep the water temperature constant. This allows the device to maintain a suitable water temperature even in cold environments. In daily use, the water inside the tank 2 can be drained by opening the drain valve 8 for water replacement. The ventilation window 10, together with the protective net 11, ensures air circulation inside the tank 2 while preventing external debris from entering the tank 2. As can be seen, the device's lighting component 54 has lifting and horizontal displacement functions. The top cover 542 can be adjusted as needed, allowing for automatic opening of the top cover 542 from the top of the tank 2, facilitating quick access to the seedling filter box 6. Simultaneously, the brightness control module adjusts the light intensity and duration, simulating natural light rhythms to promote seedling metabolism, enhance their appetite and digestion, optimize seedling distribution, and prevent excessive phototaxis leading to oxygen deficiency or crowding, thus improving seedling health and survival rate. The oxygen supply component 55 distributes air evenly into the water as microbubbles through the air supply pipe 551 and the annular pipe 553, increasing the contact area between water and air and improving dissolved oxygen levels. Combined with the water circulation driven by the reflux mechanism 3, dissolved oxygen is evenly distributed within the tank 2, effectively solving the low oxygen problem at the bottom of the tank and reducing the risk of seedling suffocation due to oxygen deficiency during high-density farming. The reflux mechanism 3 also ensures the water within the tank 2 circulates. The water flow moves the seedlings, preventing them from clustering together. Simultaneously, the flowing water encourages the seedlings to swim and exercise, improving their activity and health. It also increases oxygen levels, maintains stable water quality, and reduces the stress and toxicity of deteriorating water conditions. The heating element 332 heats the water in the return pipe 31, and the temperature sensor 333 monitors the water temperature in real time and provides feedback for adjustment, keeping the water temperature in the chamber 2 constant. This eliminates localized temperature differences caused by stagnant water flow, reduces stress on the seedlings due to temperature changes, and creates a stable temperature environment for seedling growth. The base 1 and support frame 9 provide stable support, ensuring stable operation of the seedling box. The seedling filter box 6 facilitates the separation of seedlings from the water, making it easy to clean waste and observe seedling growth. The ventilation window 10 and protective net 11 ensure air circulation in the chamber 2, preventing interference from external debris and improving the safety and controllability of the seedling environment.
