[0040] Working principle: When using this device, place the stored fishery products inside the storage box 402. Then start the condenser 201 to receive gas through the intake pipe 202. After being cooled by the condenser 201, the cold air is transmitted through the cooling pipe 203 and sprayed on the inside of the storage box 1 through the cooling nozzle 205 to quickly cool the surface of the fishery products. Then, in cooperation with the cooler 304, water in the water tank 301 is pumped through the water pumping pipe 303 and cooled, and then transported through the water delivery pipe 305 to multiple shunt pipes 307. The valves 306 on the shunt pipes 307 control the water flow rate. The cooling water is injected into the storage box 402 through the water outlet pipe 308 to directly cool the fishery products and soak them for temperature reduction;

[0041] When discharging the water inside the storage box 402, it flows into the collection pipe 502 through the sewage pipe 501 and then falls into the collection box 504. The impurities in the discharged water are filtered by the filter screen 505. The electric slider 703 is driven to move by the electric guide rail 702. The electric slider 703 drives the brush 704 to slide and clean on the top of the filter screen 505 to clean the impurities on the surface of the filter screen 505. The cleaned waste falls into the sewage box 705 under the action of the brush 704, so that the impurities can be conveniently collected;

[0042] The temperature sensors and probes in the temperature sensing module collect the temperatures of each part in real time, and the analog signals are converted into digital signals through the analog-to-digital converter. Then the digital signals are received by the data processing module. After the microprocessor analyzes and calculates the data, control instructions are generated, so that the control module can adjust the operating state of the execution unit according to the instructions, accurately control the temperature environment of the cooling equipment, water cooling device, etc. Finally, the display and operation module real-time displays the temperature and equipment status through the touch unit and the interface, and supports the operator to set parameters. The whole system realizes precise temperature control and human-computer interaction, improving the freshness preservation effect of fishery products and the intelligent level of the system.
