Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] A sample storage device for environmental monitoring, such as Figure 1-4 As shown, it includes a storage box 1, a plurality of support rods 4 are fixedly installed at the bottom end of the storage box 1, a plurality of placement boxes 2 are slidably installed in the storage box 1, the top surface of the placement box 2 is open, a box cover is hingedly installed on the top surface of the placement box 2, a temperature control component is slidably installed in the placement box 2, and a plurality of through holes 3 are opened at the bottom end of the storage box 1, and components in the temperature control component pass through the through holes 3. Figure 1 The dotted part is the liquid nitrogen delivery pipeline, a temperature sensor is installed in the placement box 2, and a display is installed on the outer surface of the box cover. The display displays the temperature. The box cover is opened, and the sampling carrier is placed in the placement box 2. Then the height of the temperature control component is adjusted up and down so that the sampling carrier completely enters the placement box 2. At the same time, the box cover blocks the top opening of the placement box 2. Then the placement box 2 is placed in the storage box 1, and the temperature control component passes through the through hole 3. When the temperature in the placement box 2 rises, the temperature control component is connected to the liquid nitrogen storage device through a pipeline. The liquid nitrogen storage device transports liquid nitrogen to the temperature control component, and then the temperature of the sampling carrier placed in the placement box 2 is controlled. During the temperature control process, the sample can be stored in the placement box 2 without contacting the outside world, and the length of the temperature control component exposed outside the storage box 1 can be used to know that the sample is stored in the placement box 2. There is no need to open it for inspection, and it can be stored for a long time. Moreover, the temperature in each placement box 2 can be adjusted according to the required temperature of the sample to meet the temperature control needs of different samples.

[0015] Specifically, the storage box 1 described in this embodiment is provided with a plurality of chutes 5 at the front and rear ends, the top of the chutes 5 is communicated with the outside, and the front and rear ends of the placement box 2 are respectively fixed with long strips 6, which can be inserted into the chutes 5. In the process of placing the placement box 2 into the storage box 1, the long strips 6 are inserted into the chutes 5, and then the placement box 2 is placed downward. With the cooperation of the chutes 5 and the long strips 6, the placement box 2 will not be offset during the placement process, which can avoid the tilting of the sampling carrier in the placement box 2 and prevent the sample from shaking out. In addition, through the cooperation of the chutes 5 and the long strips 6, the placement box 2 can also be limited to prevent the placement box 2 from moving.

[0016] Furthermore, the temperature adjustment component described in this embodiment includes: A moving box 7, wherein the moving box 7 is located in the placing box 2 and can slide in the placing box 2, a plurality of air outlets are provided at the top of the moving box 7, and an air inlet is provided at the bottom of the moving box 7; Screw holes, the screw holes are opened on the inner wall of the bottom end of the placement box 2; The top of the long tube 8 is movably connected to the bottom of the movable box 7, the top of the long tube 8 is connected to the inside of the air inlet, the bottom of the long tube 8 is used to disassemble and install the plug, the outer periphery of the long tube 8 is provided with an external thread, the long tube 8 can pass through the screw hole and cooperate with the screw hole thread.

[0017] When the temperature in the placement box 2 rises, the stopper is removed, the pipeline for transmitting liquid nitrogen is threadedly connected to the bottom end of the long tube 8, and then the liquid nitrogen is transported into the long tube 8. After the transportation is completed, the stopper is plugged into the bottom end of the long tube 8, and the liquid nitrogen is stored in the mobile box 7 and gradually discharged into the placement box 2 through the air outlet. The temperature of the sample is controlled in the closed placement box 2, and different volumes of liquid nitrogen are input according to the temperature control needs; rotating the long tube 8 can drive the mobile box 7 to move up and down in the placement box 2. For example, when the sampling carrier is just placed in the placement box 2, the bottom end of the sampling carrier contacts the top end of the mobile box 7, and does not block all the air outlets. The long tube 8 is rotated to make the mobile box 7 downward, and the sampling carrier gradually enters the placement box 2. When the sampling carrier completely enters the placement box 2, the rotation of the long tube 8 is stopped, and then the box cover is closed.

[0018] Furthermore, vertical rods 9 are fixedly installed on both sides of the outer wall of the top surface of the mobile box 7 described in this embodiment, and the two vertical rods 9 are fixedly connected by an annular sponge. The sampling carrier passes through the annular sponge, and the sampling carrier is auxiliaryly fixed by the sponge to prevent the sampling carrier from moving.

[0019] Usage process: open the box cover, place the sampling carrier into the placement box 2, the bottom end of the sampling carrier passes through the sponge and contacts with the top of the mobile box 7, then rotate the long tube 8, the mobile box 7 drives the sampling carrier to move downward, so that the sampling carrier completely enters the placement box 2, then close the box cover, and then place the placement box 2 into the storage box 1, so that the long block 6 is inserted into the slide groove 5, and the long tube 8 passes through the through hole 3, after the bottom end of the placement box 2 contacts the inner wall of the bottom end of the storage box 1, the placement box 2 is placed in the storage box 1, and the temperature sensor in the placement box 2 monitors the temperature change in the placement box 2 and transmits the information to the display on the top of the box cover. When the temperature rises, remove the plug, and the bottom end of the long tube 8 is connected to the liquid nitrogen delivery pipeline below through a pipeline, and the liquid nitrogen is delivered to the mobile box 7. After the delivery, plug the bottom end of the long tube 8 with the plug; Another installation method: When the sample needs to be stored for a long time, the placement box 2 is placed in the storage box 1, and the long tube 8 also passes through the through hole 3. The long tube 8 is directly connected to the liquid nitrogen delivery pipeline through a pipeline, and a solenoid valve is installed at the connection. When the temperature in the placement box 2 rises and the liquid nitrogen stock is already small, the controller controls the solenoid valve to open, and the liquid nitrogen enters the long tube 8. After a period of transportation, the controller controls the solenoid valve to close, and the temperature change in the placement box 2 is monitored by the temperature sensor.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
