[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0032] A soil sample storage device comprises a storage tube 1, wherein a plurality of hollow partitions 12 are arranged at the center of the storage tube 1 and are distributed at equal intervals, and a storage box 2 for containing soil samples is arranged between two adjacent hollow partitions 12, and the storage box 2 is slidably connected to the storage tube 1, and the bottom end of the storage box 2 is in contact with the top of the corresponding hollow partition 12 below it, and a gap for gas flow is left between the front and rear sides of the storage box 2 and the inner wall of the storage tube 1;

[0033] As a preferred embodiment of the present invention, the side wall of the storage cylinder 1 is provided with a plurality of groups of fixed blocks 15 distributed at equal intervals, and a single group of fixed blocks 15 is formed by two fixed blocks 15 distributed symmetrically, and the number of groups of fixed blocks 15 is consistent with the number of storage boxes 2 and corresponds one to one, and rectangular blocks 21 are provided on both the front and rear sides of the storage box 2 away from the end of the storage cylinder 1, and the rectangular blocks 21 are fixedly connected to the storage box 2 through springs 22, and the side walls of the fixed blocks 15 are provided with rectangular grooves slidably connected to the rectangular blocks 21;

[0034] Furthermore, the side wall of the storage box 2 is provided with a cylindrical groove that can accommodate the contractile spring 22 and the rectangular block 21. The two ends of the spring 22 are fixedly connected to the corresponding inner wall of the cylindrical groove end and the rectangular block 21 respectively. When the spring 22 is in a normal supporting state, the end of the rectangular block 21 away from the spring 22 passes through the corresponding rectangular groove and is flush with the side wall of the corresponding fixed block 15, so as to fix the position of the storage box 2.

[0035] A cavity 11 is provided between the inner wall and the outer wall of the storage tube 1. A semiconductor cooling sheet 3 is provided in the cavity 11 and near the top. A plurality of heat dissipation fins 31 are provided on the heat dissipation surface of the semiconductor cooling sheet 3. The ends of the heat dissipation fins 31 away from the semiconductor cooling sheet 3 pass through the storage tube 1 and extend to the outside. The heat dissipation fins 31 are cooled by the flow of external air, thereby improving the heat dissipation efficiency of the heat dissipation surface of the semiconductor cooling sheet 3 and improving the working efficiency of the cooling surface of the semiconductor cooling sheet 3.

[0036] A plurality of air holes 13 communicating with the interior of the cavity 11 are provided on the inner wall of the storage tube 1 near the bottom of the cavity 11, so that the cold air in the cavity 11 can sink into the center of the storage tube 1 through the air holes 13, thereby cooling the space in the center of the storage tube 1.

[0037] As a preferred embodiment of the present invention, a groove is provided inside the storage tube 1 and along the bottom of the bottommost hollow partition 12, and a fan blade 16 and a motor 17 are provided in the groove. The fan blade 16 is coaxially connected to the motor 17 through a rotating shaft. As is well known to those skilled in the art, after the motor 17 is powered, it drives the rotating shaft and the fan blade 16 to rotate, and then the gas passes through the holes on the hollow partition 12 at its top, thereby accelerating the gas flow rate in the space at the center of the storage tube 1, thereby improving the cooling efficiency of the gas in the space at the center of the storage tube 1.

[0038] As a preferred embodiment of the present invention, a temperature sensor 14 for detecting the temperature inside the storage cylinder 1 is provided on the inner wall of the top end of the storage cylinder 1, and a controller 5 for controlling the switch of the semiconductor cooling sheet 3 is provided inside and near the bottom end of the storage cylinder 1. When the temperature sensor 14 detects that the temperature at the center and near the top end of the storage cylinder 1 exceeds the value set by the controller 5, the controller 5 starts the semiconductor cooling sheet 3. When the temperature sensor 14 detects that the temperature at the center and near the top end of the storage cylinder 1 is lower than the value set by the controller 5, the controller 5 turns off the semiconductor cooling sheet 3.

[0039] Furthermore, the motor 17 is electrically connected to the controller 5 via a wire, so that the controller 5 can perform synchronous switching control on the motor 17 and the semiconductor cooling plate 3 .

[0040] As a preferred embodiment of the present invention, a storage slot for accommodating the controller 5 and the battery 4 is provided inside the storage tube 1 near the bottom. The controller 5, the motor 17 and the temperature sensor 14 are electrically connected to the battery 4 through wires, respectively, so that the controller 5, the motor 17 and the temperature sensor 14 can be powered by the battery 4 so that they can be used independently without the fixed socket, thereby improving the convenience of use.

[0041] When the soil sample storage device of the utility model is used, multiple soil samples or multiple soil samples of the same kind are placed in multiple storage boxes 2 respectively, and then the rectangular block 21 is pushed to move toward the side close to the storage box 2 and generate pressure on the spring 22. Then the spring 22 contracts after being stressed and is stored together with the corresponding rectangular block 21 into the corresponding cylindrical groove, so that the storage box 2 can move between the two corresponding fixed blocks 15. When the rectangular block 21 moves to correspond to the rectangular groove opened on the side wall of the fixed block 15, the rebound force of the spring 22 pushes the rectangular block 21 to move away from the storage box 2, so that the end of the rectangular block 21 away from the spring 22 passes through the corresponding rectangular groove to fix the position of the storage box 2.

[0042] Then, when the temperature sensor 14 detects that the temperature of the space at the center of the storage tube 1 is higher than the value set by the controller 5, the controller 5 starts the semiconductor refrigeration sheet 3 and the motor 17, so that the semiconductor refrigeration sheet 3 cools the inside of the cavity 11, and then the cold air sinks and enters the space at the center of the storage tube 1 through the air vent 13. At the same time, the fan blade 16 rotates to blow the cold air upward and accelerate the air flow in the space at the center of the storage tube 1, and then the gas passes through the holes on the hollow partition 12 and flows to reduce the temperature of the space at the center of the storage tube 1;

[0043] When the temperature sensor 14 detects that the temperature of the space at the center of the storage tube 1 is lower than the value set by the controller 5, the controller 5 disconnects the power supply of the semiconductor refrigeration plate 3 and the motor 17. It is worth noting that the storage tube 1 and the storage box 2 are both made of heat-insulating materials to reduce the impact of the external ambient temperature on the internal temperature of the storage tube 1.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
