[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-5 A fresh aquatic product preservation and transportation device, comprising:

[0033] Box 1, the top of box 1 is connected to box door 2 by hinge, the bottom of one side of box 1 is fixedly connected to external pump 3, the input end of external pump 3 is fixedly connected to external pipe 4, and the end of external pipe 4 away from external pump 3 extends into the interior of box 1.

[0034] The transfer pipe 5 is fixedly connected to the output end of the external pump 3. A return pipe 6 is fixedly connected to the top of one end of the tank 1. A temperature control component 7 is installed between the return pipe 6 and the transfer pipe 5. The temperature control component 7 is used to maintain the temperature of the liquid in the tank 1.

[0035] In this embodiment, a polarographic sensor 17 is fixedly connected to the bottom of the box 1, and an oxygen pump 18 is fixedly connected to the top of one side of the box 1. An oxygen supply pipe is fixedly connected to the output end of the oxygen pump 18, and one end of the oxygen supply pipe extends into the interior of the box 1.

[0036] More specifically, the polarographic sensor 17 is an electrochemical sensor that determines the concentration of dissolved oxygen by measuring the change in current between electrodes. Its main structure is as follows:

[0037] Working electrode: Made of inert materials such as platinum and gold, it participates in electrochemical reactions and is sensitive to changes in dissolved oxygen concentration.

[0038] Reference electrode: Made of a highly stable metallic material, it provides a stable reference potential for calibrating the potential of the working electrode.

[0039] Electrolyte: An electrolyte solution fills the area around the electrode, serving as a medium for ion conduction, enabling ion exchange between the working electrode and the reference electrode.

[0040] A breathable membrane: This membrane covers the surface of the working electrode and allows oxygen to pass through but not liquid, thus transferring dissolved oxygen from the water to the surface of the working electrode.

[0041] Circuitry: Includes power supply, signal amplifier, converter, etc., used to power the sensor and process the electrical signals output by the sensor.

[0042] Housing: Protects the sensor's structure and ensures its sealing and stability in underwater environments;

[0043] The principle is to apply a constant voltage between the working electrode and the reference electrode to polarize the working electrode. When dissolved oxygen in the water reaches the surface of the working electrode through the breathable membrane, the oxygen undergoes a reduction reaction on the electrode surface, generating an electric current. Since the current generated by the oxygen reduction reaction is proportional to the concentration of dissolved oxygen, the concentration of dissolved oxygen in the water can be calculated by measuring the magnitude of the current.

[0044] In summary, the polarographic sensor 17 is a mature existing technology, and will not be elaborated further here;

[0045] In this embodiment, a baffle is fixedly connected to one end of the external lead pipe 4 located inside the box 1;

[0046] More specifically, by setting up the baffle, when water is being pumped out of the external inlet pipe 4, it is possible to prevent the aquatic products inside the tank 1 from entering the external inlet pipe 4, thereby avoiding blockage of the external inlet pipe 4;

[0047] In this embodiment, the temperature control component 7 includes:

[0048] The flow control pipe 8 is fixedly connected to the end of the transmission pipe 5 away from the external pump 3. Both ends of the top of the flow control pipe 8 are fixedly connected to the transmission pipe 9. The top ends of the two transmission pipes 9 are fixedly connected to the merging pipe 10. The end of the return pipe 6 away from the box 1 is also connected to the middle of the merging pipe 10.

[0049] Temperature control box 11, a semiconductor cooling chip 12 is fixedly connected inside the temperature control box 11, and temperature conducting cylinders 13 are fixedly connected to both sides of the temperature control box 11. The ends of the two temperature conducting cylinders 13 away from the temperature control box 11 are respectively fixedly connected to the outside of the two transmission pipes 9.

[0050] A flow control component is assembled on the flow control tube 8 and is used to change the flow direction of the liquid inside the flow control tube 8.

[0051] In this embodiment, two one-way valves are provided on the confluence pipe 10, and the two one-way valves are located on both sides of the return pipe 6 respectively;

[0052] More specifically, by setting a one-way valve, the direction of liquid flow into the confluence pipe 10 can be controlled, so that the liquid can only flow to the return pipe 6;

[0053] Example 2:

[0054] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the flow control component includes:

[0055] A stabilization support 14 is fixedly connected to one end of the flow control tube 8. An electric push rod 15 is fixedly connected to the middle of the stabilization support 14. A flow control plate 16 is fixedly connected to the output end of the electric push rod 15, and the flow control plate 16 is located inside the flow control tube 8.

[0056] In this embodiment, multiple sealing grooves are provided on the outer side of the flow control plate 16, and an O-ring is fixedly connected inside each sealing groove.

[0057] More specifically, by setting the O-ring seal, the connection gap between the flow control plate 16 and the inner wall of the flow control tube 8 can be sealed to prevent uncontrollable flow of liquid in the flow control tube 8;

[0058] Furthermore, the O-ring can be made of rubber;

[0059] In this embodiment, a temperature sensor 19 is fixedly connected to the bottom of the box 1, and a PLC controller 20 is fixedly connected to one end of the box 1. The external pump 3, the semiconductor cooling chip 12, the electric push rod 15, the polarographic sensor 17, the oxygen pump 18 and the temperature sensor 19 are all electrically connected to the PLC controller 20.

[0060] More specifically, through the settings of the PLC controller 20, it is possible to centrally control the external pump 3, the semiconductor cooling chip 12, the electric push rod 15, the polarographic sensor 17, the oxygenation pump 18, and the temperature sensor 19, thereby ensuring the overall linkage.

[0061] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0062] Working principle: First, open the door 2 and place the fresh aquatic products inside the box 1. Add liquid and nutrients to the box 1 to support the survival of the aquatic products. Then close the door 2. During the transportation of aquatic products, the oxygen content of the liquid inside the box 1 is detected in real time by the polarographic sensor 17. When the oxygen content is insufficient, the oxygenation pump 18 is started to increase the oxygen content of the liquid inside the box 1 through the air supply pipe.

[0063] The temperature sensor 19 can detect the liquid temperature inside the chamber 1. When the temperature sensor 19 detects that the temperature inside the chamber 1 is too high, the electric push rod 15 is activated first to push the flow control plate 16 to move inside the flow control tube 8 until the flow control plate 16 reaches the side close to the heating end of the semiconductor cooling chip 12, thereby blocking the side of the flow control tube 8 close to the heating end of the semiconductor cooling chip 12. At the same time, the semiconductor cooling chip 12 is activated. The low temperature of the semiconductor cooling chip 12 during operation will be sent into the transmission tube 9 through one of the temperature conducting tubes 13. When the external pump 3 is activated to draw out the liquid in the chamber 1 through the external pipe 4 and send it into the cooled transmission tube 9 through the transmission tube 5 and the flow control tube 8, it can exchange heat with the transmission tube 9 to reduce the temperature of the liquid. The cooled liquid will enter the confluence tube 10 and finally return to the chamber 1 through the return tube 6.

[0064] When the internal temperature of the chamber 1 is too low, the semiconductor cooling chip 12 is activated. The high temperature generated by the semiconductor cooling chip 12 during operation will be conducted to another transmission tube 9 through another temperature conducting tube 13, causing the other transmission tube 9 to heat up. Then, the electric push rod 15 is activated, causing the flow control plate 16 to reach the side of the flow control tube 8 near the cooling end of the semiconductor cooling chip 12. The liquid that subsequently enters the flow control tube 8 will exchange heat with the transmission tube 9. The heated liquid will eventually return to the chamber 1 through the return pipe 6, thereby maintaining the liquid temperature inside the chamber 1 and preventing the aquatic products from losing their activity due to temperature differences.
