Since the adjacent baffles 9 are sleeved with the threaded rod 10, the baffles 9 will move along the axial direction of the threaded rod 10, and the rollers 16 on both sides of the multiple baffles 9 roll in the grooves 8 of the connecting block 7 to ensure that the baffles 9 move smoothly. Under the push of the adjacent baffles 9 and the action of gravity, the multiple baffles 9 move downward, and finally the top of the fish box 1 is completely opened to facilitate the loading of live fish. When the fish box 1 needs to be closed to prevent the live fish from escaping, the driving motor 11 is operated in reverse , so that the threaded rod 10 rotates in the opposite direction, and under the pull of the adjacent baffles 9, the other baffles 9 are driven to move toward the top of the fish box 1, until all the baffles 9 are tightly fitted with the top of the fish box 1, completing the closure of the top. The partition net 15 is used to separate the space inside the fish box 1, so as to facilitate the management of different types or batches of live fish. The size of the layered area can be adjusted according to the number of different types of live fish. The bottom of the partition net 15 is inserted into the corresponding two clamping blocks 21 to achieve positioning, and then the connecting column 14 is pulled upward to move it upward, so that the bottom of the connecting column 14 is flush with the bottom of the fixing plate 12. At this time, the spring 23 located in the fixing block 13 is in a squeezed state, and then The top of the partition net 15 is located under the corresponding two fixing plates 12. After the connecting column 14 is loosened, the spring 23 is reset, thereby driving the connecting column 14 to be inserted into the connecting hole 22 one by one, and finally the partition net 15 is fixed. A dissolved oxygen sensor 19 and a temperature sensor 20 are installed inside the fish tank 1 to monitor the dissolved oxygen content and temperature in the water quality in the tank in real time. The two sensors transmit the collected data to the PLC controller 18, and the PLC controller 18 analyzes the received data. When it is found that the dissolved oxygen is insufficient or the temperature is abnormal, the PLC controller 18 will automatically control the oxygenator 17 to work, and inject oxygen into the fish tank 1 to adjust The dissolved oxygen content is adjusted to maintain a suitable water quality environment and ensure the healthy survival of live fish. When the live fish needs to be transferred out of the fish carrying box 1, the operator can open the box door 5 on one side of the fish carrying box 1. The design of the box door 5 and the bottom of the transfer port 6 are snap-fitted and connected to facilitate quick opening and closing. Through the transfer port 6, the live fish can be transferred from the fish carrying box 1 using corresponding tools or equipment. The universal wheels 2 at the bottom of the fish carrying box 1 enable the entire device to be easily moved, and it is more convenient to transfer within the warehouse or between different locations.
