Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] A vegetable cold chain storage and preservation device, such as Figures 1-6 As shown, the system includes a cabinet 1, placement frames 2, partitions 201, cabinet doors 3, temperature controllers 4, water tanks 5, water inlet pipes 51, connecting pipes 6, water pumps 7, nozzles 8, connecting pipes 13, drain pipes 14, connecting frames 15, collection frames 16, and a temperature display 17. Four placement frames 2 are connected inside the cabinet 1. The bottom of each placement frame 2 is sloped, with the left side of the bottom of each frame higher than the right. Two partitions 201 are fixedly connected inside each placement frame 2, with the partitions spaced vertically. Cabinet doors 3 are hinged to the front of each placement frame 2, and a temperature display 17 is fixedly connected to the front of each cabinet door 3. Four temperature controllers 4 are fixedly connected to the rear of the cabinet 1, each extending into its corresponding placement frame 2. A water tank 5 is fixedly connected to the left side of the cabinet 1, and the top of the water tank 5 is fixedly connected to... The system is equipped with an inlet pipe 51 and a water pump 7. The water tank 5 is connected to the pumping end of the water pump 7, and the drain end of the water pump 7 is fixedly connected to a connecting pipe 6. All connecting pipes 6 extend into the placement frame 2. The part of the connecting pipe 6 extending into the placement frame 2 is rotatably connected to four nozzles 8. The nozzles 8 are located between the partition net 201 and the placement frame 2 and between the partition net 201 and the partition net 201, so that water can be sprayed on the upper and lower sides of the vegetables for preservation. All right sides of the placement frame 2 are fixedly connected to a through pipe 13. All through pipes 13 extend out of the cabinet 1. The right end of the through pipe 13 is fixedly connected to the same drain pipe 14. All right sides of the cabinet 1 are fixedly connected to a connecting frame 15. A collection frame 16 is slidably connected inside the connecting frame 15. The drain pipe 14 is fixedly connected to the connecting frame 15. The temperature display 17 is electrically connected to the temperature controller 4.

[0022] Temperature display 17 can detect and display the temperature inside the placement box 2 in real time. When the temperature inside the placement box 2 is too high, the temperature inside the placement box 2 is lowered by temperature controller 4. When the temperature inside the placement box 2 is too low, the temperature inside the placement box 2 is raised by temperature controller 4. Each temperature display 17 and temperature controller 4 detects and controls the temperature inside a single placement box 2, so that different kinds of vegetables can be placed in different placement boxes 2 to meet the specific temperature requirements of different vegetables. When vegetables need to be stored in this preservation device, water is injected into the water tank 5 through the water inlet pipe 51, the cabinet door 3 is opened, the vegetables are placed on the partition net 201, the water pump 7 draws the water in the water tank 5 into the connecting pipe 6, and the water then enters the nozzle 8 through the connecting pipe 6. The nozzle 8 sprays water to preserve the vegetables. Excess water passes through the partition net 201 and falls to the bottom of the placement box 2. The water flows along the slope of the bottom of the placement box 2 into the through pipe 13, and then into the drain pipe 14. Finally, it is stored in the collection box 16 for easy reuse of the water.

[0023] like Figures 2-5As shown, the system also includes gears 9, connecting plates 10, cylinders 11, and racks 12. A connecting plate 10 is fixedly connected to the inner left wall of the cabinet 1. A cylinder 11 is fixedly connected to the side of the connecting plate 10 away from the placement frame 2. Two racks 12 are slidably connected to both sides of the connecting plate 10. Each rack 12 is fixedly connected to the piston rod of the cylinder 11. Gears 9 are fixedly connected to the end of the nozzle 8 away from the placement frame 2, and each gear 9 meshes with a rack 12. When the nozzle 8 sprays water onto the vegetables, the piston rod of the cylinder 11 drives the rack 12 upwards. The meshing of the gears 9 and rack 12 causes the nozzle 8 to rotate. The piston rod of the cylinder 11 then drives the rack 12 downwards, causing the nozzle 8 to reverse direction. This allows for multi-angle water spraying onto the vegetables, ensuring the surface is evenly covered with water and improving the efficiency of water spraying for freshness preservation.
