Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrimp larvae temporary rearing technology, and in particular to a mobile shrimp larvae temporary rearing box. Background Technology
[0002] Shrimp larvae are small shrimp that have just hatched, typically only a few millimeters long, representing the earliest stage of shrimp growth. Shrimp larvae are generally divided into marine and freshwater larvae, each adapted to different aquatic environments. Marine shrimp larvae mainly include prawns, tiger prawns, and grass prawns, adapted to high salinity and high water temperature environments; freshwater shrimp larvae include crayfish, swamp crayfish, and river shrimp, adapted to freshwater environments.
[0003] During shrimp larvae rearing, transfer operations are frequently required, such as transferring from hatching ponds to rearing ponds or from one rearing site to another. The transfer of shrimp larvae typically involves removing them from their current environment, placing them in transport containers, transporting them to the target location, and finally placing them in the new rearing environment. This process necessitates ensuring the survival rate and health of the shrimp larvae during the transfer.
[0004] However, during the transportation of shrimp larvae, the container is subjected to ground vibrations as it moves, causing the water inside the container to shake constantly. This can lead to the shrimp larvae colliding with the inner wall of the container and getting injured, affecting their health or even their survival, resulting in losses. Utility Model Content

[0027] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.
[0028] See Figures 1 to 6 This utility model provides a mobile shrimp larvae rearing box, including a box body 2, a base 1, and a vibration damping mechanism. Multiple vibration damping mechanisms are arranged opposite each other on both sides of the bottom of the box body 2. The box body 2 is connected to the top surface of the base 1 through these mechanisms. The top of the box body 2 is open and has a detachable top plate 3. A flexible net bag 18 is suspended from the bottom surface of the top plate 3. The net bag 18 has an inverted pyramidal structure with its four sides inclined to the inner wall of the box body 2. A conical portion is provided at its bottom, and a connecting pipe 23 is connected to the conical portion. 3 extends out of the bottom surface of the box 2 and is connected to a discharge pipe 24. The discharge pipe 24 is located on the bottom surface of the base 1 and is equipped with a discharge valve 25. At least four hanging ropes 19 are arranged circumferentially around the bottom edge of the net bag 18. The ends of the hanging ropes 19 are connected to magnetic blocks 20. An iron sheet 29 is pre-embedded in the bottom of the box 2. The magnetic blocks 20 are magnetically connected to the pre-embedded iron sheet 29. The top plate 3 is provided with an openable cover plate 5. A vent box is provided on the top of the cover plate 5. The vent box is used to connect the air inside and outside the box 2.
[0029] When transferring shrimp larvae using a temporary holding box, first open the cover 5 and place the shrimp larvae and aquaculture water into the box 2. The shrimp larvae are placed inside the net bag 18. At this time, the magnetic block 20 at the end of the hanging rope 19 is attracted to the top surface of the iron plate 29. The flexible net bag 18 separates the shrimp larvae from the four inner walls of the box 2. The net bag 18 can reduce the shaking of the aquaculture water during the movement of the box 2, and at the same time prevent the shrimp larvae from colliding with the inner walls of the box 2, thereby reducing the risk of injury to the shrimp larvae. During transportation, the vibration damping mechanism can buffer the vibration of the road surface, reduce bumps, and facilitate the smooth movement of the box 2, reducing the loss of shrimp larvae.
[0030] Once the shrimp larvae rearing box reaches its destination, the discharge valve 25 is opened. The four sides of the flexible net bag 18 are inclined against the inner wall of the box body 2. The conical part of the net bag 18 has an inclined angle, using gravity to guide the shrimp larvae to gather towards the connecting pipe 23. The shrimp larvae and the culture water are concentrated at the bottom of the conical part of the net bag 18 and discharged through the connecting pipe 23, which facilitates the discharge of all shrimp larvae and prevents shrimp larvae from remaining in the net bag 18. After the shrimp larvae discharge is completed, the top plate 3 can be raised, and the hanging rope 19 pulls the magnetic block 20, separating the magnetic block 20 from the iron plate 29. As the connecting pipe 23 extends, it is easy to clean the bottom of the net bag 18. The operation is simple and convenient.
[0031] Preferably, the vibration damping mechanism includes a support plate 10, a slide rod 8, and a helical spring 9. The multiple support plates 10 are arranged opposite each other on both sides of the housing 2. The slide rod 8 is correspondingly arranged on the top surface of the base 1 below the support plate 10. The slide rod 8 and the support plate 10 are slidably connected. The helical spring 9 is sleeved on the slide rod 8 and located between the support plate 10 and the base 1.
[0032] The vibration damping mechanism is used to buffer the vibration of the box 2. When the temporary holding box is moved, when the support plate 10 is vibrated, the helical spring 9 can undergo elastic deformation to absorb and store vibration energy, thereby effectively reducing the vibration amplitude transmitted to the shrimp larvae temporary holding box, reducing the impact on the box 2, and facilitating the transfer of shrimp larvae.
[0033] Preferably, the assembly also includes a cylinder 11, a piston 12, an intake pipe 13, a one-way valve 14, a two-way valve 15, and an exhaust pipe 16. The cylinder 11 is located on the top surface of the support plate 10. The piston 12 is slidably disposed within the cylinder 11. The slide rod 8 is connected to the bottom surface of the piston 12. The intake pipe 13 and the exhaust pipe 16 are located on the top of the cylinder 11. The one-way valve 14 is located on the intake pipe 13. The two-way valve 15 is located on the exhaust pipe 16. The exhaust pipe 16 extends into the bottom of the housing 2. The portion of the exhaust pipe 16 located inside the housing 2 has multiple exhaust holes 17.
[0034] When the holding box is moved, the box 2 will bounce. When the box 2 is impacted and jumps upward, the slide rod 8 drives the piston 12 to move downward relative to the cylinder 11. The cylinder 11 generates negative pressure. External air flows into the cylinder 11 through the air inlet pipe 13 and one-way valve 14. When the box 2 descends, it will compress the helical spring 9. The slide rod 8 drives the piston 12 to move upward relative to the cylinder 11. The piston 12 squeezes the air in the cylinder 11, and the air pressure increases. One-way valve 15 opens, and air enters the air outlet pipe 16 from the cylinder 11 and is discharged through the air outlet 17. Bubbles are generated at the bottom of the box and float upward, increasing the oxygen content in the aquaculture water and improving the survival rate of shrimp larvae.
[0035] Preferably, the vent box includes a housing 6 and a partition 28. The top of the cover plate 5 is provided with a vent hole 7. The lower end of the housing 6 is open and covers the vent hole 7. The partition 28 is provided on one side of the inner wall of the housing 6, and its other end is at a certain distance from the inner wall of the housing 6. The top of the housing 6 is provided with a vent hole 27, which is located above the partition 28.
[0036] During the movement of the temporary holding tank, the water inside the tank will shake, and air will continuously spray out from the air outlet 17 on the air outlet pipe 16, generating bubbles at the bottom of the tank and continuously floating upwards, forming foam on the liquid surface. After the foam accumulates, it will enter the inner cavity of the shell 6 through the first air outlet 7. After being blocked by the partition 28, the foam will burst, and the breeding water will flow back into the tank 2 along the partition 28. The air will flow out to the outside through the second air outlet 27, preventing the foam from overflowing and reducing the loss of breeding water.
[0037] Preferably, the system also includes a support rod 21 and a roller 22, wherein the support rod 21 is disposed on the bottom surface of the base 1 and the roller 22 is disposed at the bottom of the support rod 21.
[0038] When the temporary care box needs to be moved, the rollers 22 allow it to slide easily on various surfaces, whether it is a smooth concrete surface or a rough dirt surface, enabling quick and smooth movement and improving operational flexibility.
[0039] Preferably, a push-pull handle 26 is also included, which is disposed opposite to the side of the base 1.
[0040] When the holding box is moved, the operator can move the heavy object more easily by pushing and pulling the handle 26. Especially when the holding box is full of shrimp larvae and water, its weight is large. The operator can use the method of pulling in front and pushing in the back, which can more effectively distribute and reduce the physical burden during the handling.
[0041] Preferably, the top plate 3 has handles 4 on both sides of its top surface.
[0042] The handle 4 provides a point of leverage for the operator, who can easily lift the top plate 3 through the handle 4 to clean the inside of the box 2, thus facilitating the maintenance of the temporary holding box.
[0043] Preferably, it also includes T-shaped locking posts 30, a plurality of T-shaped locking posts 30 being rotatably disposed on the top surface of the housing 2, the top plate 3 being provided with a through groove 31, and the T-shaped locking posts 30 being inserted into the through groove 31 and then rotated to lock.
[0044] When it is necessary to assemble and fix the top plate 3 and the housing 2, first rotate the T-shaped locking post 30 so that the length direction of the head of the T-shaped locking post 30 is aligned with the length direction of the through groove 31. Then, place the top plate 3 vertically downward on top of the housing 2 using the handle 4. After inserting the T-shaped locking post 30 into the through groove 31, rotate it 90°. The length of the T-shaped locking post 30 is greater than the width of the through groove 31, thus achieving locking. When it is necessary to remove the top plate 3, simply rotate the T-shaped locking post 30 90° so that the length direction of the head of the T-shaped locking post 30 is aligned with the length direction of the through groove 31, and lift the top plate 3 vertically upward to remove it. The locking and disassembly process is relatively simple and quick.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
