In the traditional transportation method, in order to ensure the survival rate of fish, the fish and water can be placed in a sealed and oxygenated container for transportation through a sealed transportation method. Its characteristics are small size and convenient transportation. Generally, for adult fish transportation, it is not necessary to change water midway within 8 hours. The shipping seal is large and the survival rate is high. One oxygenation can keep the fry alive in the container for more than 20 hours. Specifically, plastic bag oxygenation and plastic barrel oxygenation and sealed transportation methods can be used.

[0080] The principle and advantages of multi-layer separated water circulation live fish preservation and transportation device:

[0081] The fish storage bag 21 is then pulled out of the U-shaped plate 11 and the sealing plate 23 is rotated upward to open the loading and unloading port 211, so that the fish can be loaded into the fish storage bag 22 from the loading and unloading port 211. The sealing plate 23 is then closed to push the storage box 21 into the inner side of the U-shaped plate 11. Finally, the sealing plate 23 is pressed against the outer side of the storage box 21 by sliding the locking rod 3 downward, so that the sealing plate 23 seals the loading and unloading port 211. At the same time, the storage box 21 can be pressed against the inner side of the U-shaped plate 11 to prevent the storage box 21 from loosening during transportation. At this time, the suction nozzle 232 on one side of the sealing plate 23 is in contact with the suction nozzle 232 on the outer side of the storage box 21. The liquid pipes 212 are aligned with each other and are squeezed and sealed by a sealing ring, and the liquid inlet hose 231 runs through the inside of the pipe sleeve 214. The pipe sleeve 214 limits the liquid inlet hose 231 at the bottom of the support plate 213, so that the output end of the liquid inlet hose 231 is located at the end of the fish storage bag 22 away from the loading and unloading port 211, and the bottom of the storage box 21 is tilted downward toward the loading and unloading port 211, so that impurities generated by the live fish during transportation can be concentrated near the liquid suction pipe 212 and sucked out, and the water inside the fish storage bag 22 can be purified by an external water circulation system; finally, the transport box 1 is hoisted by the lifting ring 7, and after hoisting, the water inlet diverter A114 and the water outlet manifold A115 outside the transport box 1 are connected to the water circulation system on the transport vehicle, so as to facilitate the connection of the fish storage bag 22 inside each transport box 1 to the external water circulation system.

[0082] The advantages are that each live fish can be stored separately through the fish storage bag 22 to prevent the live fish from being squeezed, lacking oxygen and bumped during transportation, and each fish storage bag 22 is oxygenated by water circulation, so the water quality can be purified while ensuring the survival rate of the live fish; at the same time, the fish storage bag 22 is indirectly sealed by the sealing plate 23 after the fish is loaded, thereby improving the sealing efficiency of the fish storage bag 22, and the sealing of the sealing plate 23 and the storage box 21 is completed by the locking rod 3, and the fish storage bag 22 is convenient to open and seal by sliding the locking rod 3 during loading and unloading, thereby improving work efficiency.

[0083] When loading fish, the preservation component 2 in the multi-layer partitioned water circulation live fish preservation and transportation device of the present application uses the electric push rod 41 to drive the locking rod 3 to move upward, first release the compression seal on the sealing plate 23, and then continue to rise the locking rod 3 to the fish loading state position, and pull the storage box 21 outward from the U-shaped layer plate 11 so that the roller 29 at the bottom of the storage box 21 rolls inside the wheel groove 14. At this time, there is no water inside the fish storage bag 22. When the roller 29 moves to the top of the lower groove 15, the roller 29 enters the lower groove 15 under the action of its own gravity, so that the storage box 21 is The loading and unloading opening 211 on one side of 21 rotates upward with the pin 13 as the center to form a certain elevation angle, and at this time, the blocking rod 233 on the outer side of the sealing plate 23 rotates upward and automatically opens under the obstruction of the locking rod 3, so as to facilitate the loading of fish. When loading fish, it is only necessary to put the fish head into the loading and unloading opening 211, and the live fish can slide into the fish storage bag 22 along the inclined downward direction, and there is no need to manually stuff the fish into the fish storage bag 22; when the fish is loaded, the loading and unloading opening 211 is pressed downward to disengage the roller 29 from the lower groove 15, and then the storage box 21 is pushed into the inner side of the U-shaped layer plate 11. At this time The sealing plate 23 rotates downward and resets under the action of its own gravity, and finally the sealing plate 23 and the storage box 21 are sealed by sliding the locking rod 3 downward; it should be noted that when the electric push rod 41 drives the locking rod 3 to be in the fish loading state, the electric push rod 41 pushes the vertical plate 42 to slide upward on the outside of the U-shaped layer plate 11 through the lifting plate 44, so that the vertical plate 42 drives the locking rod 3 to move upward, and when the locking rod 3 gradually moves away from the sealing plate 23 along the sliding hole A17, it drives the vertical plate 42 to move horizontally, and then the connecting plate 46 at the bottom of the vertical plate 42 moves horizontally on the outside of the sliding rod A442 , to ensure the stability of the vertical plate 42. At the same time, when the vertical plate 42 rises, it will drive the fixed support plate 48 on the outside to rise, so that the support plate 48 drives the sliding pin B49 to slide along the guide rail assembly 6 on the outside of the U-shaped layer plate 11. The V-shaped track 61 in the guide rail assembly 6 is horizontally set toward the slider 5, so that the sliding pin B49 can generate a pulling force on the connecting rod 410 when it moves upward from the bottom of the V-shaped track 61, and then the connecting rod 410 drives the horizontal wedge block 54 to move the slider 5 out of the lower groove 15, and then when the roller 29 moves to the top of the lower groove 15, the storage box 21 can meet the condition of forming an elevation angle.

[0084] It is worth mentioning that the above-mentioned fish loading method has the following advantages:

[0085] Advantage 1: when the electric push rod 41 drives the locking rod 3 to release the seal on the sealing plate 23, the locking rod 3 can be automatically located in the fish loading state, so that when the storage box 21 is pulled out, the sealing plate 23 can be automatically rotated upward to open, so as to facilitate the fish loading work, and will not affect the resetting action of the sealing plate 23.

[0086] Advantage 2: When the storage box 21 is pulled out a certain distance, the roller 29 will be pressed into the lower groove 15 by its own gravity. At this time, the center of gravity of the storage box 21 will shift and automatically rotate upward to form an elevation angle, so that the fish can be quickly loaded into the fish storage bag 22 when loading.

[0087] Advantage three: the elevation angle formed by the storage box 21 can prevent the fish already loaded from escaping from the fish storage bag 22 due to stress when loading fish into other fish storage bags 22. There is no need to load fish into several fish storage bags 22 simultaneously and check them individually, which brings convenience to the fish loading work.

[0088] When the transport box 1 in the multi-layer partitioned water circulation live fish preservation and transportation device of the present application is lifted and loaded onto a vehicle, the transport box 1 is lifted and loaded onto the transport equipment by the lifting equipment in cooperation with the lifting ring 7. When the lifting ring 7 pulls the lifting rope 71 upward, the lifting rope 71 drives the connecting block 72 to slide upward along the sliding hole C113. At this time, one of the lifting ropes 71 pulls the tooth plate 88 to slide upward on the inner side of the U-shaped layer plate 11, so that the tooth plate 88 drives the rotating shaft 85 to rotate through the gear 87, and then drives the reducing cam 86 on the outer side of the rotating shaft 85 to rotate toward the outer side of the slide plate 82. When the reducing cam 86 rotates, the outer diameter gradually increases, which generates an extrusion force on the slide plate 82, so that the slide plate 82 moves along the slide rod C81 toward the storage box 21. The outside is approaching, and the other side of the storage box 21 is blocked by the locking rod 3. When the slide plate 82 pushes the extrusion plate 84 to fit the outside of the storage box 21, the reducing cam 86 continues to rotate to compress the spring 83. When the connecting block 72 reaches the top of the sliding hole C113 and the tooth plate 88 reaches the top of the transport box 1, the lifting ring 7 drives the transport box 1 away from the ground; when the transport box 1 is placed on the transport vehicle, the reducing cam 86 is squeezed by the slide plate 82, and the friction between the two can be in a stable state, thereby clamping the storage box 21 on the inner side of the U-shaped layer plate 11, which can prevent the locking rod 3 from reducing the extrusion effect on the sealing plate 23 when it is worn, causing the storage box 21 to shake.

[0089] It is worth mentioning that the above hoisting method has the following advantages:

[0090] Advantage 1: The entire weight of the transport box 1 during hoisting is used to trigger the squeezing action of the squeezing assembly 8, so that the squeezing assembly 8 can further press the storage box 21 after it is installed to prevent the storage box 21 from shaking.

[0091] Advantage two, when pulling out the storage box 21, the energy stored in the squeezing assembly 8 will be released through the spring 83, which has a certain boosting effect on the storage box 21, making it convenient to pull out the storage box 21 when unloading the fish.

[0092] Advantage three, when the spring 83 releases its elastic force, the slide plate 82 and the squeeze plate 84 are in a relaxed state. At this time, the tooth plate 88 slides downward and resets under the action of its own gravity, and then drives the variable diameter cam 86 to automatically reverse and reset, so that the slide plate 82 and the squeeze plate 84 do not cause resistance when the storage box 21 is pushed in, so as to be used continuously and repeatedly.

[0093] When the fish is unloaded, the preservation component 2 in the multi-layer separated water circulation live fish preservation and transportation device of the present application pushes the locking rod 3 to the uppermost position, i.e., the position of the fish unloading state, through the electric push rod 41; at this time, the locking rod 3 will pass the position of the fish loading state, and then will pull the slider 5 out from the inner side of the lower groove 15. In order to facilitate the storage box 21 to be pulled out a greater length, when the locking rod 3 continues to rise after passing the fish loading position, the support plate 48 drives the sliding pin B49 to continue to move upward to the fish unloading state, and at the same time, the lifting plate 44 starts to push the U-shaped plate 47 to move upward, so that the U-shaped plate 47 drives the vertical wedge block 53 to push the slider 5 into the lower groove 15, and at the same time, the V-shaped track 61 guides the sliding pin B49 to push the connecting rod 410, so that the connecting rod 410 pushes the horizontal wedge block 54 to reset and release the restriction on the slider 5, so as to ensure that the slider 5 is unloaded When the fish is unloaded, it can automatically slide to the inner side of the lower groove 15, and then the storage box 21 is pulled out. At this time, the roller 29 passes the top of the lower groove 15 through the slider 5. When the roller 29 moves to the end of the wheel groove 14, the pin 13 and the roller 29 are closest to each other. Under the effect of the overall center of gravity offset of the storage box 21, the storage box 21 is forced to rotate downward around the pin 13 to form a depression angle. At this time, the locking rod 3 does not contact the blocking rod 233, so that the sealing plate 23 automatically opens under the action of its own gravity, and then the fish in the fish storage bag 22 is quickly unloaded; it should be noted that during the fish unloading process, the fish storage bag 22 is supported by the support plate 213, and the support plate 213 is arranged along the length direction of the fish storage bag 22 to prevent the fish from entering and exiting the fish storage bag 22. The twisting deviation of the fish storage bag 22 itself affects the loading and unloading efficiency.

[0094] It is worth mentioning that the above installation method has the following advantages:

[0095] Advantage 1: When unloading fish, the electric push rod 41 drives the locking rod 3 to be located at the highest point, preventing the locking rod 3 from blocking the storage box 21 and making it impossible to pull out the fish for unloading, and at the same time releasing the seal of the sealing plate 23.

[0096] Advantage two, when the locking rod 3 moves to the uppermost position, the locking rod 3 can drive the slider 5 to automatically slide into the lower groove 15, so that it is more labor-saving when pulling out the subsequent storage box 21. There is no need to adjust the state of the slider 5 separately when unloading the fish. Only the height of the locking rod 3 needs to be controlled, which makes the operation more convenient.

[0097] Advantage three, when the storage box 21 drives the roller 29 to move to the end of the wheel groove 14, the storage box 21 can automatically rotate downward around the pin 13 to form a depression angle due to the offset of its own center of gravity, so as to facilitate the unloading of the live fish inside the fish storage bag 22. There is no need to take out the live fish one by one, thereby improving the efficiency of fish unloading.
