Description

Technical Field

[0001] The invention relates to the technical field of fry transportation, and in particular to a silver pomfret stress response inhibition type transportation box. Background Art

[0002] Transporting silver pomfret fry is a skill-intensive operation requiring meticulous management. Due to their lack of hard scales, silver pomfret are less resilient to stress and are prone to mortality during transportation. This is especially true during the later stages of fry development, when hatchery-raised fry need to be transferred to offshore cages, often leading to high transport losses. This transfer process from land-based fry rearing centers to offshore aquaculture is highly specialized, requiring simultaneous assurance of three key elements: maintaining the physiological health of the fry, ensuring a stable transport environment, and ensuring efficient transport operations. Silver pomfret farming typically utilizes a step-by-step system of "indoor fry rearing followed by on-growing in offshore cages." This approach makes fry transportation an essential and crucial step in production.

[0003] To improve the survival rate of fry during transportation, the prior art has proposed many solutions. For example, the prior art KR102649266B1 is designed to maintain a stable growth environment for loaded live fish during long transportation processes such as export, thereby improving transportation quality. The live fish are quantitatively administered a mineral composition containing magnesium, calcium, and water stored internally from 48 to 72 hours before loading to unloading, thereby forming a stable ecological environment for the live fish through growth, non-specific biological defense activity, and stress suppression. Another example is the prior art KR1019930018812, which provides a transport box for transporting fish. The transport box includes: an air outlet hole mounted on a fixed transport box, a bubble pump for generating air bubbles for supplying oxygen to the fixed transport box, and a portable battery for supplying power to the bubble pump and compartment. However, the above prior art is not suitable for transporting silver pomfret fry. Silver pomfret transportation requires avoiding stress reactions. Its body surface lacks hard scales for protection and is sensitive to changes in dissolved oxygen and sudden temperature changes in the water. Summary of the Invention

[0004] The purpose of the present invention is to provide a stress-response-inhibiting transport box for silver pomfret, solve the problem of survival rate of high-value silver pomfret fry during transportation, optimize the physiological characteristics and behavioral habits of silver pomfret, stabilize the temperature and dissolved oxygen in the box, significantly improve the survival rate during transportation and reduce stress response.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solution: a silver pomfret stress response inhibition transport box.

[0006] A silver pomfret stress-suppressing transport box includes a second box body, a first pump body for conveying gas disposed outside the second box body, and at least two spaced-apart first aeration assemblies disposed within the second box body. The first aeration assembly includes a first aeration pipe disposed vertically within the second box body, the first pump body communicating with the first aeration pipe via a first conveying pipe, an aeration head disposed around the first aeration pipe, and a first filter plate disposed within the first aeration pipe that is movable along the axis of the first aeration pipe. The aeration head at the lower portion of the first aeration pipe is a microporous aeration head, while the aeration head at the upper portion of the first aeration pipe is a perforated aeration head. A first filter plate is disposed on at least one side of the first filter plate, and the first filter plate is connected to the first filter plate in an array arrangement.

[0007] The transport box of the present invention adopts an aeration scheme to supplement oxygen to the environment during transportation, and makes the water in the transport box flow, helping the water flow in the box to form a state similar to living water and drive the flow of oxygen inside the box, effectively reducing the stress response of silver pomfret fry during transportation and improving the survival rate. In the aeration scheme, the adjustable first filter plate moves along the axis of the first aeration pipe, intercepting impurities (such as fry excrement and mucus) in real time, reducing or avoiding blockage of the first aeration pipe, and ensuring long-term stable oxygen supply.

[0008] In the process of gas passing through the first aeration pipe, the gas moves upward from the bottom of the first aeration pipe, and the first filter plate stays at the bottom of the first aeration pipe due to gravity in the absence of initial thrust. After the gas is input upward from the bottom of the first aeration pipe, it needs to pass through the first filter plate, and then push the first filter plate and be filtered when passing through the first filter plate and the first filter sheet. The water also needs to be filtered when passing through the first filter plate, so as to play a filtering and protective effect on the input port below the first aeration pipe, and in the process of the first filter plate being pushed upward by the airflow, the first filter plate can scrape and clean the inner wall of the first aeration pipe to keep the inside of the first aeration pipe clean. When the first filter plate is aerated inside the first aeration pipe, its upper and lower The airflow redistribution function is realized during movement: the displacement of the first filter plate can change the airflow effect in the first aeration pipe, which helps the upper aeration to produce larger bubbles and moderate water flow, and uses the flowing water flow to assist the heat dissipation of the upper water body. The formed flowing water body can help the dissolved oxygen in the box to move and reduce the waves in the upper water body of the transport box caused by shaking during transportation, thereby reducing the probability of wave-induced stress reaction of the fry. The lower layer of the first aeration pipe releases tiny bubbles to stably maintain the dissolved oxygen at the bottom (≥5mg / L), avoid the aggregation of fry due to lack of oxygen or the accumulation of metabolic waste, and ensure weak aeration in the lower layer to reduce the disturbance of low-temperature water body, thus forming a temperature gradient control with the upper water body, solving the problem of silver pomfret fry being sensitive to ambient temperature.

[0009] According to one embodiment of the present invention, the upper end of the first aeration tube is open and coaxially connected to the first sleeve, the end of the first sleeve is sealed, and the side of the first sleeve is surrounded by a first opening. The upper end of the first aeration tube is designed to naturally decelerate the airflow when entering the first sleeve, preventing the high-pressure airflow from directly impacting the fish school and achieving axial airflow buffering. The surrounding opening structure on the side of the first sleeve allows oxygen to enter the water body in a multi-directional and slow-release manner, forming a three-dimensional aeration network, ensuring uniform distribution of dissolved oxygen in the transport box, and helping to reduce waves in the water body above the transport box caused by shaking during transportation during the outward output process, forming a stable water environment, and reducing the stress swimming of the fry caused by violent water flow.

[0010] According to one embodiment of the present invention, a first sliding rod is disposed above the first filter plate. The first sliding rod has a circular plate at its end facing away from the first filter plate. The circular plate has a diameter less than or equal to the diameter of the first aeration tube. This circular plate is breathable, and the first sliding rod is used to control the range of movement of the first filter plate.

[0011] According to one embodiment of the present invention, the bottom of the first aeration tube has an inlet sealing plate with an opening that communicates with the first delivery tube. This opening precisely aligns with the first delivery tube, allowing airflow to enter perpendicularly along the axis of the first aeration tube. This avoids turbulent flow losses associated with traditional side-inlet systems and improves airflow efficiency.

[0012] According to one embodiment of the present invention, the outer wall of the first aeration tube has a support block, one end of the support block is connected to the first aeration tube, and the other end is connected to the second box body, which can position the first aeration tube in multiple directions to prevent the first aeration tube from being offset due to transportation bumps.

[0013] According to one embodiment of the present invention, a second aeration assembly is installed at the bottom of the second tank. Connected to the second aeration assembly via a first delivery pipe, this assembly forms a microbubble matrix at the bottom of the second tank. This dual-path aeration system works in tandem with the first aeration assembly to create a three-dimensional aeration network, minimizing the dissolved oxygen gradient found in traditional transport tanks. More importantly, dual-path aeration ensures more uniform water disturbance, reducing the risk of fish flocking in oxygen-rich areas.

[0014] According to one embodiment of the present invention, the second aeration assembly includes an aeration base plate connected to the first conveying pipe, the aeration base plate is provided with a first cylinder with an upper end opening, and the inner wall of the first cylinder is surrounded by a guide vane. A first rod body is provided in the first cylinder, one end of the first rod body is connected to the aeration base plate, and the other end is connected to a guide vane arranged parallel to the aeration base plate. The surface of the guide vane is provided with openings; the side of the guide vane is connected to a flexible strip. The guide vane is tilted at an angle of 45°. The spiral guide vane on the inner wall of the first cylinder is combined with the flexible strip to convert the airflow into a rotating upward vortex, which prolongs the bubble retention time. The opening design of the guide vane cuts large bubbles when the airflow passes through. The solution provided by the present invention eliminates the direct water flow generated by traditional aeration, and reduces the number of abnormal collisions between fish schools.

[0015] According to one embodiment of the present invention, a first box body is disposed outside a second box body; a filler block is disposed between the second box body and the first box body. A filler block is disposed between the second box lid of the second box body and the first box lid of the first box body. The filler block is made of a deformable material and fills the gap between the second box body and the first box body. The present invention utilizes a double-box and flexible filler composite structure, significantly improving environmental stability and fry survival rate during transportation through the dual optimization of dynamic buffering and temperature isolation. The double-layer box body combined with the filler block structure delays the transmission of external temperature fluctuations by up to 10%.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the transport box of the present invention adopts an aeration scheme to supplement oxygen to the environment during transportation, and makes the water in the transport box flow, helping the water flow in the box to form a state similar to living water and drive the flow of oxygen inside the box, effectively reducing the stress response of silver pomfret fry during transportation and improving the survival rate.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0032] Example 1:

[0033] Attached picture Figure 1 -Attached Figure 8 As shown, the present invention provides a transport box for suppressing the stress response of silver pomfret. The transport box of the present invention comprises a second housing 20, a first pump body 40 for conveying gas disposed externally therefrom, and at least two spaced-apart first aeration assemblies 30 disposed within the second housing 20. The first aeration assembly 30 includes a first aeration tube 31 vertically disposed within the second housing 20. The first pump body 40 communicates with the first aeration tube 31 via a first delivery pipe 41. An aeration head 32 is disposed around the outside of the first aeration tube 31 and communicates with the interior thereof. The first aeration tube 31 includes a first filter plate 361, which is movable along the axis of the first aeration tube 31. The aeration head 32 at the lower portion of the first aeration tube 31 is a microporous aeration head, while the aeration head 32 at the upper portion of the first aeration tube 31 is a perforated aeration head. At least one side of the first filter plate 361 includes a first filter disc 36, which is arranged in an array and connected to the first filter disc 36.

[0034] The transport box of the present invention adopts an aeration scheme to supplement oxygen to the environment during transportation, and to form a flowing state of water in the transport box, thereby helping the water flow in the box to form a state similar to living water and driving the flow of oxygen inside the box, effectively reducing the stress response of silver pomfret fry during transportation and improving the survival rate. In the aeration scheme, the adjustable first filter plate 361 moves along the axis of the first aeration tube 31, intercepting impurities (such as fry excrement and mucus) in real time, reducing or avoiding blockage of the first aeration tube 31, and ensuring long-term stable oxygen supply.

[0035] When the gas passes through the first aeration pipe 31 and moves upward from the bottom of the first aeration pipe 31, the first filter plate 361 stays at the bottom of the first aeration pipe 31 due to gravity in the absence of an initial thrust. After the gas is input upward from the bottom of the first aeration pipe 31, it needs to pass through the first filter plate 361, which pushes the first filter plate 361 upward and is filtered when passing through the first filter plate 361 and the first filter sheet 36. The water also needs to be filtered when passing through the first filter plate 361, so as to have a filtering protection effect on the input port below the first aeration pipe 31. In addition, when the first filter plate 361 is pushed upward by the airflow, the first filter plate 361 can scrape and clean the inner wall of the first aeration pipe 31 to keep the inside of the first aeration pipe 31 clean. The first filter plate 361 is at the During aeration within an aeration tube 31, its upward and downward movement redistributes airflow. The displacement of the first filter plate 361 alters the airflow within the first aeration tube 31, contributing to the generation of larger bubbles and moderate water flow in the upper aeration layer. The flowing water assists in heat dissipation in the upper water layer, and the resulting flowing water reduces damage caused by wall collisions or sinking to the bottom due to static conditions. It also reduces waves in the upper water layer of the transport box caused by shaking during transportation, thereby reducing the probability of wave-induced stress reactions in the fry. The lower layer of the first aeration tube 31 releases tiny bubbles, maintaining stable dissolved oxygen levels (≥5 mg / L) at the bottom, preventing the aggregation of fry due to lack of oxygen or the accumulation of metabolic waste. It also ensures weak aeration in the lower layer, reducing disturbances in the low-temperature water. This creates a temperature gradient with the upper water layer, addressing the temperature sensitivity of silver pomfret fry.

[0036] The first aeration tube 31 has an open top and is coaxially connected to a first sleeve 34. The first sleeve 34 is sealed at its end, and first openings 38 are arranged around its sides. The open top of the first aeration tube 31 naturally decelerates airflow upon entering the first sleeve 34, preventing high-pressure airflow from directly impacting the fish and providing axial airflow buffering. The surrounding openings on the sides of the first sleeve 34 allow oxygen to enter the water in a multi-directional, slow-release manner, forming a three-dimensional aeration network. This ensures uniform dissolved oxygen distribution within the transport box and helps reduce ripples in the water above the transport box caused by swaying during transport. This creates a stable water environment and reduces stressful swimming caused by intense currents on the fry.

[0037] A first sliding rod 35 is positioned above the first filter plate 361. The end of the first sliding rod 35 facing away from the first filter plate 361 comprises a circular plate whose diameter is less than or equal to the diameter of the first aeration tube 31. This circular plate is breathable, and the first sliding rod 35 controls the range of movement of the first filter plate 361.

[0038] The first aeration tube 31 has an inlet sealing plate 37 at its bottom, which has an opening that communicates with the first delivery tube 41. A support block 33 is provided on the outer wall of the first aeration tube 31. The opening of the inlet sealing plate 37 precisely aligns with the first delivery tube 41, allowing airflow to be input vertically along the axis of the first aeration tube 31, avoiding turbulent losses caused by traditional side air intake and improving airflow utilization.

[0039] One end of the support block 33 is connected to the first aeration pipe 31 , and the other end of the support block 33 is connected to the second box 20 , which can position the first aeration pipe 31 in multiple directions to prevent the first aeration pipe 31 from being offset due to transportation bumps.

[0040] A second aeration assembly 60 is positioned at the bottom of the second housing 20 and connected to the second aeration assembly 60 via the first delivery pipe 41. This creates a microbubble matrix at the bottom of the second housing 20 and works in conjunction with the first aeration assembly 30 to provide a dual-path aeration system. The second aeration assembly 60 and the first aeration assembly 30 work together to form a three-dimensional aeration network, minimizing the dissolved oxygen gradient found in traditional transport boxes. This dual-path aeration system ensures more uniform water disturbance, reducing the risk of fish flocking in oxygen-rich areas.

[0041] The second aeration assembly 60 includes an aeration base plate 61 connected to the first conveying pipe 41. The aeration base plate 61 is provided with a first cylinder 62 with an open upper end, and a guide plate 64 is arranged around the inner wall of the first cylinder 62. A first rod body is provided in the first cylinder 62, one end of the first rod body is connected to the aeration base plate 61, and the other end is connected to a guide plate 63 arranged parallel to the aeration base plate 61. The surface of the guide plate 63 is provided with openings; the side of the guide plate 63 is connected to a flexible strip. The guide plate is arranged at an angle, in this embodiment, the angle is 45°. The spiral guide plate on the inner wall of the first cylinder 62 is combined with the flexible strip to convert the airflow into a rotating and rising vortex, which prolongs the bubble retention time. The opening design of the guide plate cuts large bubbles when the airflow passes through. The solution provided by the present invention eliminates the direct water flow generated by traditional aeration and reduces the number of abnormal collisions between fish schools.

[0042] The first box 10 is located outside the second box 20; a filler block 22 is provided between the second box 20 and the first box 10. A filler block 22 is located between the second box cover 21 of the second box 20 and the first box cover 11 of the first box 10. The filler block 22 is made of a deformable material and fills the gap between the second box 20 and the first box 10. The present invention utilizes a dual-box and flexible filler composite structure, significantly improving environmental stability and fry survival rate during transportation through the dual optimization of dynamic buffering and temperature isolation. The double-layer box structure combined with the filler block 22 delays the transmission of external temperature fluctuations by up to 10%.

[0043] Example 2:

[0044] In this embodiment, see the attached Figure 4 -Attached Figure 6 As shown, the first sleeve 34 is positioned relative to the opening at the end of the first aeration tube 31, allowing the medium flowing from the first aeration tube 31 to enter the interior of the first sleeve 34. The other end of the first sleeve 34 is sealed, typically in a dome-shaped structure. A connector is provided at this dome structure, which abuts or plugs into the second housing 21 of the second housing 20 above. A sealing ring is placed at the connection with the second housing 21 to prevent loosening. This defines the position of the first sleeve 34 relative to the second housing 21, and indirectly defines the position of the first aeration tube 31, ensuring its vertical position during transportation. The dome structure at the upper end of the first sleeve 34 plugs into the housing cover, and combined with the connection scheme between the bottom opening and the first sleeve 34, ensures the vertical stability of the first aeration tube 31 during transportation.

[0045] A first connecting rod 39 is provided on the outside of the first sleeve 34 and the first aeration tube 31. One end of the first connecting rod 39 is hingedly connected to the outer wall of the first aeration tube 31, allowing the first connecting rod 39 to rotate relative to the outer wall of the first aeration tube 31. A clip is provided on the outer wall of the first sleeve 34, and the end of the first connecting rod 39 has a bent plate structure that engages with the clip on the outer wall of the first sleeve 34. Rotation of the first connecting rod 39 relative to the first aeration tube 31 causes the bent plate structure to engage or disengage with the clip. Multiple first connecting rods 39 are provided on the outer wall of the first aeration tube 31, allowing for assembly and disassembly of the first sleeve 34 and the first aeration tube 31 through a multi-point connection. This design of the first connecting rods 39 enables simultaneous locking of the first sleeve 34 and the first aeration tube 31 at multiple points.

[0046] Example 3:

[0047] This embodiment is based on the embodiment 1, and further optimizes the solution as follows: Figure 1 , Attachment Figure 2 As shown, the first box body 10 is arranged outside the second box body 20. The structure and shape of the first box body 10 are consistent with the second box body 20, and the size is larger than the second box body 20. The first box body 10 is arranged outside the second box body 20 to form protection and heat preservation.

[0048] The protective measures are as follows: the outer wall of the first box body 10 has an anti-collision strip 16, which increases the friction effect of adjacent components on the adjacent first box body 10. When there is a need to transport tens of thousands of fish fry in a single trip, multiple transport boxes need to be used. Adjacent transport boxes may be scratched during transportation. The anti-collision strip 16 reduces or avoids scratches, and the fixation of the transport boxes on the vehicle needs to be checked repeatedly.

[0049] The first box 10 has two side panels 13 that can be opened and closed. One side of the side panel 13 has a hinged portion connected to the first box 10. The two side panels 13 form an opening and closing door. When the side panels 13 are open, the second box 20 can be removed from the side of the first box 10. The first box 10 has a strip groove on the side, and a baffle 12 is installed outside the strip groove. During transportation, it is necessary to monitor environmental parameters within the transport box, such as sensors. The relevant circuits enter the first box 10 through the strip groove and then enter the second box 20 in turn to connect with the corresponding electrical components. The baffle 12 and the strip groove provide regularity and protection for the circuits.

[0050] The first housing 10 has an opening at the top, allowing the second housing 20 to be placed in and removed. A corresponding first lid 11 is located on top of the first housing 10, with a rubber strip 17 between the first lid 11 and the second housing 10 filling the gap. A light-transmitting panel 15 is located on the side of the first housing 10, allowing the second housing 20 to be observed from within. The second housing 20 is typically made of acrylic or tempered glass, providing a light-transmitting effect. Two first slots 14 are located horizontally at the bottom of the first housing 10 for use with a forklift.

[0051] The first delivery pipe 41 of the first pump body 40 can pass through the first tank body 10 and the second tank body 20 in sequence and communicate with the first aeration assembly 30 and the second aeration assembly 60 respectively.

[0052] Example 3:

[0053] This embodiment is based on the embodiment 1, and further optimizes the solution as follows: Figure 1 , Attachment Figure 9 -Attached Figure 11As shown, a second pump body 50 is provided outside the first box body 10 and the second box body 20, and one end of the second pump body 50 is connected to a second delivery pipe 51, which can pass through the first box body 10 and the second box body 20 in sequence and the end thereof is arranged inside the second box body 20, and the end of the second delivery pipe 51 is connected to an inlet sleeve 54 located in the second box body 20 through an extension pipe body 52. The inlet sleeve 54 is a conical sleeve structure, and a groove is arranged around its side to allow the medium to move in the direction of the slotted box extension pipe body 52. The sleeve 54 is provided with a bending plate 53, which has a horizontal plate. The horizontal plate is parallel to the axis of the inlet sleeve 54 and is arranged above the inlet sleeve 54, with a distance between the two. The horizontal plate has an extended bent plate structure at the end away from the inlet of the extended tube body 52. The extended bent plate structure has an angle relative to the horizontal plate and is arranged adjacent to the inlet sleeve 54. The horizontal plate has a vertical plate connected to the inlet sleeve 54 near the inlet end of the extended tube body 52. The vertical plate has a bent plate body below, which has an inclined angle relative to the axis of the inlet sleeve 54. The conical structure of the inlet sleeve 54 (preferably a cone angle of 35° in this embodiment) increases the water flow velocity. At the same time, a spiral flow field is formed under the guidance of the extended bent plate structure of the bending plate 53, which improves the efficiency of impurity capture. The transition zone formed by the extended bent plate structure and the inlet sleeve 54 in the direction of the inlet sleeve 54 allows the fry to escape for 0.5-1 seconds after sensing the change in flow velocity, forming a fluid buffer zone to prevent the fry from being discharged or being damaged during sewage discharge.

[0054] A circular hole is opened in the middle of the vertical plate, which is installed corresponding to the extension tube 52 and can allow fluid to enter the extension tube 52 through the circular hole after passing through the slot of the inlet sleeve 54. The edge of the inlet sleeve 54 has an extended mounting plate for bolting with the vertical plate.

[0055] Example 4:

[0056] This embodiment provides a further optimization scheme based on the scheme of Example 1. Optical dissolved oxygen sensors are respectively installed in the upper, middle and lower layers of the second box 20 to monitor dissolved oxygen (DO). The optical dissolved oxygen sensor has a range of 0-20 mg / L and an accuracy of ±0.1 mg / L. Platinum resistance temperature sensors (PT100) with a range of 0-40°C and an accuracy of ±0.1°C are installed in the upper and lower areas of the second box 20 to monitor water temperature. Glass electrode pH sensors with a range of 6-9 pH and an accuracy of ±0.1 pH are installed in the upper and lower areas of the second box 20 to monitor pH value. An infrared CO2 sensor with a range of 0-1000 ppm and an accuracy of ±10 ppm is installed in the top area of the second box 20 to monitor carbon dioxide (CO2). Whether to place a flow meter in the box is determined based on transportation requirements. The data acquisition method is that the sensor node transmits wirelessly to the main controller via RS485 or LoRa. The PLC or embedded controller processes the data in real time and triggers an emergency action: dissolved oxygen is too low → start aeration.
