[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] As Figure 1 - Figure 9 shown, a sample classification and storage device for environmental monitoring includes a storage box 1. A preparation structure 2 is installed at the top of the inner cavity of the storage box 1. A storage structure 3 is installed on the outer wall of the inner cavity of the storage box 1. The storage box 1 includes a box body 11. A classification module 12 is installed at the top of the box body 11. A placement opening 113 is opened at the top of the box body 11 and on one side of the classification module 12;

[0038] A temperature control module 13 is installed on the outer wall of the right side of the box body 11. A pick-up opening 112 is installed at the bottom of one outer wall of the box body 11. An auxiliary opening 111 is opened at the top of the box body 11;

[0039] On the outer wall at the bottom of the classification module 12 and at the top inside the box body 11, a scanner 121 is installed. On the top inside the box body 11 and on the lower surface of the placement opening 113, a hardened glass 15 is installed. On the top inside the box body 11 and on one side of the hardened glass 15, a first electric telescopic rod 16 is installed. At the bottom inside the box body 11, an inclined sponge 14 is installed.

[0040] The preparation structure 2 includes an auxiliary box 21. On the left side inside the auxiliary box 21, a second stepping motor 22 is installed. On the outer wall on the right side inside the auxiliary box 21, a first detection camera 23 is installed. At the driven end of the second stepping motor 22 and in the middle inside the auxiliary box 21, a first iron sheet conveyor belt 221 is installed. On the top of the first iron sheet conveyor belt 221, a placement rack 24 is provided.

[0041] Inside the placement rack 24, a sample test tube 243 is provided. At the bottom of the placement rack 24, a magnet 241 is installed. At the bottom of the magnet 241, a partition plate 242 is installed. On both sides of the magnet 241, limit frames 244 are installed.

[0042] It should be noted that in this embodiment, when classifying and storing samples, the samples are placed inside the placement rack 24, and then the samples are placed into the auxiliary opening 111. Then, when the first detection camera 23 detects the placement rack 24, the second stepping motor 22 is started to drive the first iron sheet conveyor belt 221 to drive, and the placement rack 24 is driven into the inner cavity of the hardened glass 15 and lands on the top of the plastic lining plate 163. At the same time, both sides of the limit frame 244 fall into the inside of the plastic lining plate 163. Then, the scanner 121 scans the bar code pasted on the outer wall of the sample test tube 243. The scanner 121 only has the functions of scanning and data transmission, and transmits the data to the classification module 12. Then, according to the data statistics of the classification module 12, the analysis is carried out, and then the classification is carried out to control other structures for storage. The scanner 121 usually uses a two-dimensional code or bar code scanner device and has the function of automatically scanning and transmitting information. And the temperature inside the box body 11 is controlled by the temperature control module 13. The detailed functions of the temperature control module 13 include:

[0043] Monitoring function, control function, data processing and display function, data recording and communication function, etc. In the conventional functional structure, it can be set as the following functional modes through the combination of common functional modules:

[0044] Temperature monitoring: The temperature control module 13 monitors the temperature change inside the storage box 1 in real time through a temperature sensor. For example, the DHT11 sensor can be used, which can measure both temperature and humidity and transmit the data to the controller for processing.

[0045] Humidity Monitoring: Some temperature control modules also have the function of humidity monitoring, which can obtain the humidity information inside the storage box in real time, so as to comprehensively consider the influence of temperature and humidity on sample preservation.

[0046] Heating Control: When the temperature inside storage box 1 is lower than the set value, the temperature control module 13 will automatically start the heater to increase the temperature inside the box, ensuring that the samples are stored in a suitable temperature environment.

[0047] Refrigeration Control: On the contrary, when the temperature is too high, the temperature control module 13 will control the refrigeration equipment (such as a fan or condenser) to work, reducing the temperature inside the box and maintaining temperature stability.

[0048] Ventilation Control: According to the temperature and humidity conditions, the temperature control module 13 can also control the opening or closing of the ventilation equipment to adjust the air circulation inside the box, preventing excessive humidity or uneven temperature.

[0049] Data Processing: The built-in controller (such as STM32) of the temperature control module 13 will process and analyze the temperature and humidity data collected by the sensors, and automatically adjust the working state of the heating or refrigeration equipment according to the preset algorithms and control strategies.

[0050] Data Display: The current temperature and humidity values, as well as information such as the set temperature range, are displayed in real time through a display screen (such as an LCD), facilitating the user to intuitively understand the environmental conditions inside the storage box.

[0051] Data Recording: The temperature control module 13 can record the temperature and humidity change data over a period of time, which can be used for subsequent analysis and statistics to help the user understand the stability of the storage environment.

[0052] Communication Function: It has the ability to communicate with a host computer or other devices. For example, through an RS485 interface or Modbus-RTU protocol, the temperature and humidity data are transmitted to an external system to achieve remote monitoring and management.

[0053] Alarm Function: When the temperature or humidity inside storage box 1 exceeds the set safety range, the temperature control module 13 will emit an audible and visual alarm signal to remind the user to take timely measures to ensure the safety of the samples.

[0054] Energy-saving Mode: In some cases, the temperature control module 13 can enter the energy-saving mode, automatically adjusting the power of the heating or refrigeration equipment according to actual needs, reducing energy consumption while ensuring the basic stability of the storage environment.

[0055] An operating table 161 is installed on the outer wall of the bottom of the first electric telescopic rod 16. A first stepping motor 164 is installed on the outer wall of the top of the operating table 161. One end of the bottom of the first stepping motor 164 is driven and a second gear 1641 is installed on the lower surface of the operating table 161. A third gear 1642 is installed at the bottom of the second gear 1641. A chain 1643 is engaged with the outer wall of the second gear 1641. A fourth gear 1644 is engaged with the inner side of the chain 1643. One end of the bottom of the first electric telescopic rod 16 is rotatably connected to two rotating columns 162. A plastic lining plate 163 is fixedly connected to the outer walls of the two rotating columns 162. A first gear 1621 is engaged with the outer wall of the third gear 1642. The inner side of the first gear 1621 is fixedly sleeved with the outer wall of the right rotating column 162.

[0056] It should be noted that in this embodiment, the data collection of the barcode is simplified by the classification module 12, and the first electric telescopic rod 16 is controlled. When the first electric telescopic rod 16 is started, the first iron sheet conveyor belt 221 does not operate. Then, the first electric telescopic rod 16 is used to drive the placement rack 24 to descend to the upper surface of the second iron sheet conveyor belt 331, and the magnet 241 magnetically attracts the upper surface of the second iron sheet conveyor belt 331 through the isolation plate 242. Then, the first stepping motor 164 is started. One end of the bottom of the first stepping motor 164 drives the second gear 1641 to rotate, and at the same time drives the third gear 1642 to rotate. When the second gear 1641 rotates, it is engaged with the chain 1643, so that the inner side of the chain 1643 is engaged with the outer wall of the fourth gear 1644, and the left rotating column 162 is driven to rotate. At the same time, the outer wall of the third gear 1642 is directly engaged with the outer wall of the first gear 1621, driving the right rotating column 162 to rotate, so as to control the plastic lining plate 163 installed on the outer walls of the left and right rotating columns 162 to rotate and disengage from the inner side of the limit frame 244. Then, the first electric telescopic rod 16 is controlled to drive the plastic lining plate 163 to rise and reset.

[0057] The storage structure 3 includes a storage plate 31. On one side of the top of the storage plate 31, a third stepping motor 33 is installed. One end of the third stepping motor 33 for transmission is installed with a second iron sheet conveyor belt 331. At the top of the inner cavity of the storage plate 31, a fourth stepping motor 332 is installed. One end of the fourth stepping motor 332 for transmission is installed with a third iron sheet conveyor belt 333. On the left side of the top of the storage plate 31, an electric push rod 32 is installed. At the top of the electric push rod 32, a second detection camera 321 is installed. An emission port 36 is opened at the top of the storage plate 31. Inside the emission port 36, a fifth stepping motor 34 is installed. One end of the fifth stepping motor 34 for transmission on one side is installed with a rotating frame 341. Inside the rotating frame 341, a rubber roller 342 is rotatably connected. At the top of the fifth stepping motor 34, an installation box 35 is installed. Inside the top of the installation box 35, a second electric telescopic rod 351 is installed. One end of the second electric telescopic rod 351 is installed with a baffle 352.

[0058] It should be noted that in this embodiment, when it falls onto the upper surface of the second iron sheet conveyor belt 331 and the third stepping motor 33 is started, when one end of the third stepping motor 33 for transmission drives the second iron sheet conveyor belt 331 to move to the classification area, and according to the data detected by the background, the second detection camera 321 of the corresponding line is started. Moreover, when the second detection camera 321 of the corresponding line detects the placement rack 24, the data is transmitted to the background. Then, the background starts the electric push rod 32, and one end of the electric push rod 32 is used to push the outer wall of one side of the placement rack 24, so that the placement rack 24 enters the upper surface of the third iron sheet conveyor belt 333 of the corresponding line. At the same time, the second electric telescopic rod 351 inside the top of the installation box 35 in the classification area is started in advance, so that one end of the second electric telescopic rod 351 pushes the baffle 352 to extend out. When the third iron sheet conveyor belt 333 moves the placement rack 24 to the inside of the baffle 352, the baffle 352 is extended and retracted by the second electric telescopic rod 351 to bring the placement rack 24 onto the upper surface of the rotating frame 341, and it slides to the inside of the emission port 36 through the rubber roller 342, thus realizing storage. When taking out, the required sample is also selected by operating the classification module 12. By starting the fifth stepping motor 34, the outer wall on the left side of the rotating frame 341 is rotated towards the inside of the emission port 36, so as to expand the gap at the bottom of the placement rack 24 leading to the inside of the emission port 36. When the rotating frame 341 rotates to 90° vertically inside the emission port 36, it means that the emission port 36 is completely opened, so that the bottom of the placement rack 24 falls from the inside of the emission port 36 onto the upper surface of the inclined sponge 14, and then it is taken from the entrance of the picking port 112.

[0059] The working principle of the present invention is as follows: when classifying and storing samples, the samples are placed inside the placement rack 24 and then placed in the auxiliary port 111. The placement rack 24 is detected by the first detection camera 23, and then the second stepper motor 22 is started to drive the first iron conveyor belt 221 to drive the placement rack 24 into the inner cavity of the hardened glass 15 and fall on the top of the plastic lining plate 163. At the same time, the two sides of the limit rack 244 fall into the inner side of the plastic lining plate 163. Then, the scanner 121 scans the stripe code on the outer wall of the sample test tube 243. The scanner 121 only has scanning and data transmission functions, and transmits the data to the classification module 12. Then, according to the data counted by the classification module 12, it is analyzed and classified and controlled to other structures for storage. The temperature control module 13 is used to control the temperature in the inner cavity of the box body 11.

[0060] The data collection of the bar code is simplified by the classification module 12, and the No. 1 electric telescopic rod 16 is controlled. When the No. 1 electric telescopic rod 16 is started, the No. 1 iron conveyor belt 221 will not run. Then the No. 1 electric telescopic rod 16 is used to drive the placement rack 24 to descend to the upper surface of the No. 2 iron conveyor belt 331, and the magnet 241 is magnetically attracted to the upper surface of the No. 2 iron conveyor belt 331 through the isolation plate 242. Then the No. 1 stepper motor 164 is started, and the No. 2 gear 1641 is driven to rotate by one end of the bottom transmission of the No. 1 stepper motor 164, and the No. 3 gear 1642 is driven to rotate at the same time. When the second gear 1641 rotates, it meshes with the chain 1643, so that the inner side of the chain 1643 meshes with the outer wall of the fourth gear 1644, and drives the left rotating column 162 to rotate. At the same time, the outer wall of the third gear 1642 directly meshes with the outer wall of the first gear 1621, driving the right rotating column 162 to rotate, so that the plastic lining plates 163 installed on the outer walls of the rotating columns 162 on the left and right sides are controlled to rotate and disengage from the inner side of the limit frame 244, and then control the first electric telescopic rod 16 to drive the plastic lining plate 163 to rise and reset;

[0061] By falling onto the upper surface of the second iron sheet conveyor belt 331 and starting the third stepping motor 33, when the end driven by the third stepping motor 33 drives the second iron sheet conveyor belt 331 to move to the sorting area, and according to the data detected by the background, the second detection camera 321 of the corresponding line is started. Moreover, when the second detection camera 321 of the corresponding line detects the placement rack 24, the data is transmitted to the background. Then, the electric push rod 32 is started through the background. One end of the electric push rod 32 is used to push the outer wall of one side of the placement rack 24, so that the placement rack 24 enters the upper surface of the third iron sheet conveyor belt 333 of the corresponding line. At the same time, the second electric telescopic rod 351 inside the top of the installation box 35 in the sorting area is started in advance, so that one end of the second electric telescopic rod 351 pushes the baffle 352 to extend the baffle 352. When the third iron sheet conveyor belt 333 moves the placement rack 24 to the inside of the baffle 352, the baffle 352 is telescoped by the second electric telescopic rod 351 to bring the placement rack 24 onto the upper surface of the rotating frame 341, and it slides to the inside of the discharge port 36 through the rubber roller 342, thus realizing storage. When taking out, the required sample is also selected by operating the sorting module 12. By starting the electric push rod 32, the outer wall on the left side of the rotating frame 341 is driven to rotate towards the inside of the discharge port 36, so as to expand the gap at the bottom of the placement rack 24 leading to the inside of the discharge port 36. When the rotating frame 341 rotates to 90° vertically inside the fifth stepping motor 34, it means that the discharge port 36 is fully opened, so that the bottom of the placement rack 24 falls from the inside of the discharge port 36 onto the upper surface of the inclined sponge 14, and then it is taken from the entrance of the picking port 112.

On one side of the top of the storage board (31), a third stepping motor (33) is installed. At the driven end of the third stepping motor (33), a second iron sheet conveyor belt (331) is installed. At the top of the inner cavity of the storage board (31), a fourth stepping motor (332) is installed. At the driven end of the fourth stepping motor (332), a third iron sheet conveyor belt (333) is installed; On the left side of the top of the storage board (31), an electric push rod (32) is installed. At the top of the electric push rod (32), a second detection camera (321) is installed; By falling onto the upper surface of the second iron sheet conveyor belt (331), start the third stepping motor (33). When the driven end of the third stepping motor (33) drives the second iron sheet conveyor belt (331) to move to the classification area, and according to the data detected by the background, start the second detection camera (321) of the corresponding line. Moreover, when the second detection camera (321) of the corresponding line detects the placement rack (24), transmit the data to the background. Then, through the background, start the electric push rod (32), and use one end of the electric push rod (32) to push the outer wall of one side of the placement rack (24) to make the placement rack (24) enter the upper surface of the third iron sheet conveyor belt (333) of the corresponding line.

3. The sample classification and storage device for environmental monitoring according to claim 2, wherein: On the top of the storage board (31), a discharge port (36) is opened. Inside the discharge port (36), a fifth stepping motor (34) is installed; At the driven end on one side of the fifth stepping motor (34), a rotating frame (341) is installed. Inside the rotating frame (341), a rubber roller (342) is rotatably connected; On the top of the fifth stepping motor (34), an installation box (35) is installed. Inside the top of the installation box (35), a second electric telescopic rod (351) is installed. At one end of the second electric telescopic rod (351), a baffle (352) is installed; Start the second electric telescopic rod (351) inside the top of the installation box (35), so that one end of the second electric telescopic rod (351) pushes the baffle (352) to extend the baffle (352). When the third iron sheet conveyor belt (333) moves the placement rack (24) to the inside of the baffle (352), then extend and retract the baffle (352) through the second electric telescopic rod (351) to bring the placement rack (24) onto the upper surface of the rotating rack (341) and slide it to the inside of the discharge port (36) through the rubber roller (342), thus achieving storage; When taking out, select the required sample by operating the classification module (12). By starting the fifth stepper motor (34), drive the outer wall on the left side of the rotating rack (341) to rotate towards the inside of the discharge port (36), so as to expand the gap at the bottom of the placement rack (24) leading to the inside of the discharge port (36). When the rotating rack (341) rotates to 90° vertically inside the discharge port (36), it means that the discharge port (36) is fully opened, so that the bottom of the placement rack (24) falls from the inside of the discharge port (36) onto the upper surface of the inclined sponge (14), and then is taken from the entrance of the pickup port (112).
