Since a pull rope is installed at the bottom of the cover plate, the pull rope passes through the inside of the pulley, so that when the cover plate is flipped, the movable mesh plate will be pulled by the pull rope and move toward one side inside the fixed mesh cage. When the movable mesh cage stops moving, the driving motor can be started again. The driving motor drives the movable tube and the lifting block to move upward through the screw rod. After the lifting block moves upward, the clamping block can move to the inside of the clamping slot. At this time, the lifting block can drive the movable mesh plate to move upward. At this time, the aquatic product inside the movable mesh plate will also move upward with the movable mesh plate to the upper part of the fresh-keeping box, and then the movable mesh plate can be pulled to move while the cover plate is opened, and then the aquatic product can be driven to rise through the movable mesh plate, thereby achieving the effect of facilitating the fishery product to be fished out.

[0022] Second: In the present invention, the movable tube can be driven to move up and down inside the fresh-keeping box through the lifting mechanism, and then the inner wall of the fresh-keeping box can be cleaned by the cleaning brush on the movable tube. While cleaning, the second water pump is started, and the second water pump generates suction above the inside of the movable tube through the second corrugated tube, and then the turbid water near the cleaning brush due to cleaning can be sucked into the inside of the movable tube through the water suction port, and the turbid water can be discharged from the inside of the filter box through the downpipe. The filter box can filter the water and then send it into the water storage tank for storage, so as to replenish the water when the water amount inside the fresh-keeping box is insufficient.

[0023] Third: In the present invention, when the movable tube moves up and down, the sliding sleeve moves on the spiral rod along with the movement of the movable tube, thereby driving the spiral rod to rotate, and the spiral rod drives the transmission shaft to rotate through the transmission bevel gear, and the transmission shaft drives the rotating shaft to rotate through the transmission bevel gear. The rotation of the rotating shaft can drive the stirring blade to rotate, and the rotation of the stirring blade can disperse the ice cubes floating on the water surface, so that the ice cubes dropped from the ice delivery tube can be dispersed to various places inside the fresh-keeping box, thereby ensuring the uniformity of the temperature inside the fresh-keeping box.

[0024] Fourthly: In the present invention, the filter element can filter the water sucked in by the first water pump, and filter out the feces and other substances of aquatic products in the water. By moving the block at the bottom of the mounting tube upward, one end of the mounting tube can be taken out from the inside of the filter tube. At this time, the filter tube can be moved upward to be removed from between the mounting tube and the water pumping pipe. At this time, the movable door can be opened, and then the filter tube can be taken out from the inside of the water storage tank, so as to facilitate the cleaning of the filter element.

At this time, the movable door 46 can be opened, and then the filter pipe 42 can be taken out from the inside of the water tank 2, so as to facilitate the cleaning of the filter element 43.

[0047] Specific implementation steps: aquatic products are placed inside the fresh-keeping box 1, and water is filled inside the fresh-keeping box 1. The ice maker 4 can make ice cubes, and then send them into the fresh-keeping box 1 through the ice delivery pipe 5, so that the water inside the fresh-keeping box 1 is in a low-temperature state, thereby reducing the metabolism of the aquatic products, thereby achieving a fresh-keeping effect on the aquatic products. The water inside the fresh-keeping box 1 can be sucked in by the first water pump 8, and then sent into the water through the movable pipe 10 and the water outlet 23, thereby accelerating the diffusion speed of oxygen inside the water, further increasing the fresh-keeping effect;

[0048] At the same time, through the setting of the lifting mechanism, when the aquatic products in the fresh-keeping box 1 are to be fished out, the screw rod 12 is first driven to rotate by the driving motor 11, and then the movable tube 10 and the lifting block 17 can be driven to move to a position below the height of the block 18 through the mounting block 13, and then the cover 3 can be flipped open. Since a pull rope 15 is installed at the bottom of the cover 3, the pull rope 15 passes through the inside of the pulley 14, so that when the cover 3 is flipped, the movable mesh plate 7 will be pulled by the pull rope 15 and move toward one side inside the fixed mesh cage 6. When the movable mesh cage 7 stops moving, the driving motor 11 can be started again. The driving motor 11 drives the movable tube 10 and the lifting block 17 to move upward through the screw rod 12. After the lifting block 17 moves upward, the block 18 can move to the inside of the card slot 19. At this time, the lifting block 17 can drive the movable mesh plate 7 to move upward. At this time, the aquatic products inside the movable mesh plate 7 will also move upward with the movable mesh plate 7 to the upper part of the fresh-keeping box 1, so as to facilitate the fish The aquatic products can be fished out.
