[0026] Please refer to Figures 1-5 As shown in the figure, the present utility model is a freezing device for tuna freshness preservation, including a bottom plate 1 and a tank body 2 fixedly installed on the top of the bottom plate 1. A driving mechanism and a flipping mechanism are arranged on the bottom plate 1;

[0027] The driving mechanism includes a motor slot 3 opened on the top of the bottom plate 1. A motor 4 is fixedly installed on the bottom inner wall of the motor slot 3. A rotating shaft 5 is fixedly installed on the output shaft of the motor 4. The top end of the rotating shaft 5 extends into the tank body 2 and is rotationally connected with the tank body 2. A turntable 6 is fixedly installed at the top of the rotating shaft 5. A large gear 7 is fixedly sleeved on the outer wall of the rotating shaft 5.

[0028] Among them, as Figure 2 shown, a plurality of fixing plates 8 are fixedly installed on the top of the turntable 6. A plurality of limiting plates 9 are arranged on the top of the turntable 6. A plurality of springs 10 are fixedly installed on the sides of the plurality of fixing plates 8 and the plurality of limiting plates 9 close to each other respectively.

[0029] By setting to synchronously move three limiting plates 9 outwards first, during the process of the three limiting plates 9 moving outwards, the springs 10 will be compressed. Put the tuna between the three limiting plates 9. After placing it well, the three limiting plates 9 will move inwards under the push of the springs 10 to fix the tuna. Through the cooperation of the limiting plates 9 and the springs 10, tunas of different volumes can be fixed, which is beneficial to improving the practicability of the device.

[0030] Among them, as Figure 4 shown, a plurality of first fixing blocks 11 are arranged in the tank body 2. Outer freezing pipes 12 are respectively rotatably installed on the plurality of first fixing blocks 11. A plurality of spray heads 13 are respectively fixedly installed on the outer walls of the plurality of outer freezing pipes 12. The bottom ends of the plurality of outer freezing pipes 12 all extend out of the tank body 2 and are rotationally connected with the tank body 2. A plurality of small gears 14 are respectively fixedly sleeved on the outer walls of the plurality of outer freezing pipes 12. The small gears 14 are meshed with the large gear 7.

[0031] During the process of spraying cold air through the nozzle 13, the motor 4 can be started. The motor 4 drives the synchronous rotation of the rotating shaft 5, the large gear 7, and the tuna on the top of the turntable 6. Since the large gear 7 meshes with multiple small gears 14, the large gear 7 can drive the rotation of multiple small gears 14 when it rotates. As a result, during the rotation of multiple outer freezing tubes 12, the nozzles 13 thereon can be driven to spray cold air. By driving the turntable 6 and the outer freezing tubes 12 to rotate through the motor 4, the freezing efficiency of the tuna can be improved, and the freezing effect on the hidden parts due to the immobility of the tuna can be reduced.

[0032] As shown in Figure 4 the figure, inner freezing tubes 15 are respectively rotatably installed in several outer freezing tubes 12. A first connecting pipe 16 is fixedly installed at the bottom ends of several inner freezing tubes 15. A refrigerator 17 is fixedly installed on the top of the bottom plate 1. A second connecting pipe 18 is fixedly installed on the outer wall of the refrigerator 17. The end of the second connecting pipe 18 extends into the tank body 2 and is fixedly connected to the first connecting pipe 16.

[0033] During the refrigeration of the tuna, the refrigerator 17 can be started to generate cold air. The cold air is respectively delivered to multiple inner freezing tubes 15 through the second connecting pipe 18 and the first connecting pipe 16. Multiple inner freezing tubes 15 fill multiple outer freezing tubes 12, and multiple outer freezing tubes 12 spray cold air through the nozzles 13 on their outer walls.

[0034] As shown in Figure 5 the figure, the flipping mechanism includes two second fixing blocks 19 fixedly installed on the outer wall of the tank body 2. A top cover 20 is rotatably installed on the two second fixing blocks 19. A round rod 21 is fixedly installed on the top cover 20. A support plate 22 is fixedly installed on the outer wall of the tank body 2. A sliding rod 23 is fixedly installed on the top of the support plate 22.

[0035] When the tank body 2 needs to be opened, the hydraulic cylinder 26 is started to drive the slider 24 to descend in cooperation with the sliding rod 23. During the descent of the slider 24, the connecting rod 25 and the top cover 20 on the connecting rod 25 are driven to rotate through the two second fixing blocks 19.

[0036] As shown in Figure 3 the figure, a slider 24 is slidably installed on the outer wall of the sliding rod 23. A connecting rod 25 is rotatably installed on the outer walls of the slider 24 and the round rod 21. A hydraulic cylinder 26 is fixedly installed on the top of the support plate 22. The output shaft of the hydraulic cylinder 26 is fixedly connected to the slider 24. Several moving wheels 27 are rotatably installed at the bottom of the bottom plate 1.

[0037] By setting the hydraulic cylinder 26 to drive the top cover 20 to rotate, manpower can be saved and work efficiency can be improved.

[0038] A specific application of this embodiment is as follows: First, synchronously move three limit plates 9 outward. During the outward movement of the three limit plates 9, the spring 10 will be compressed. Place the tuna between the three limit plates 9. After placing it, the three limit plates 9 will move inward under the push of the spring 10 to fix the tuna. Through the cooperation of the limit plates 9 and the spring 10, tuna of different volumes can be fixed, which is beneficial to improving the practicability of the device. When refrigerating the tuna, the refrigerator 17 can be started to generate cold air. The cold air is respectively transported to multiple inner freezing pipes 15 through the second connecting pipe 18 and the first connecting pipe 16. The multiple inner freezing pipes 15 fill the multiple outer freezing pipes 12, and the multiple outer freezing pipes 12 spray cold air through the nozzles 13 on their outer walls. During the process of the nozzles 13 spraying cold air, the motor 4 can be started. The motor 4 will drive the rotating shaft 5, the large gear 7 and the tuna on the top of the turntable 6 to rotate synchronously. Since the large gear 7 meshes with multiple small gears 14, the large gear 7 can drive the multiple small gears 14 to rotate when it rotates. Thus, when the multiple outer freezing pipes 12 are rotating, the nozzles 13 thereon can be driven to spray cold air. By driving the turntable 6 and the outer freezing pipes 12 to rotate through the motor 4, the freezing efficiency of the tuna can be improved, and the freezing effect on the hidden parts can be reduced due to the immobility of the tuna. When the tank body 2 needs to be opened, start the hydraulic cylinder 26 to drive the slider 24 to descend in cooperation with the sliding rod 23. During the descent of the slider 24, the connecting rod 25 and the top cover 20 on the connecting rod 25 will rotate through the two second fixing blocks 19. By driving the top cover 20 to rotate through the hydraulic cylinder 26, manpower can be saved and the working efficiency can be improved.
