[0002] A smart laboratory based on Internet of Things (IoT) technology is a modern laboratory system that deeply integrates the concept of IoT with the laboratory environment. It achieves interconnectivity among various elements by installing sensors and network-connected devices on various equipment, instruments, samples, and environmental monitoring points within the laboratory. Through IoT-based on-site sampling devices, it can accurately record temperature and humidity data in real time at the moment of sampling, storing and transmitting this data along with the sample data.

After the device is started, its sensors will monitor the temperature and humidity of the sampling environment in real time and compare them with the preset thresholds.

[0004] In existing technologies, some smart laboratory on-site sampling devices based on IoT technology require aligning the mounting base or bracket of the humidity collector with the pre-drilled mounting holes, inserting screws through the mounting holes on the base or bracket, and then using a screwdriver or electric screwdriver to screw the screws into the mounting holes. This complex operation increases the time cost of installation. Therefore, to address the above shortcomings, a smart laboratory on-site sampling device based on IoT technology is proposed to solve the aforementioned problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart laboratory on-site sampling device based on Internet of Things (IoT) technology includes a support box and multiple temperature and humidity collectors. A square plate is fixedly connected inside the support box. A drive assembly for driving subsequent components to rotate is fixedly connected to the top side of the square plate. Rotating plates are rotatably connected to the top four sides of the drive assembly. Limit frames are slidably connected to the outside of the rotating plates. Two push rods are slidably connected to the top of the rotating plates. A push plate is fixedly connected to the adjacent side of each pair of push rods. Two positioning posts are slidably connected inside each pair of push plates. Springs are sleeved on the outside of the positioning posts. Multiple hook-shaped plates are fixedly connected to the bottom side of the temperature and humidity collectors.

[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes a cylinder, the bottom side of which is fixedly connected to the top side of the square plate, and the drive end of the cylinder is fixedly connected to a transmission plate.

[0012] As a further description of the above technical solution:

[0013] The limiting frame is fixedly connected to two limiting posts on the outside. The transmission plate is rotatably connected to one end of a plurality of rotating plates on all four sides. The outside of each pair of limiting posts is rotatably connected to the top of the support box on all four sides.

[0014] As a further description of the above technical solution:

[0015] The bottom side of the temperature and humidity collector is in contact with the top side of the rotating plate, and the outer sides of each pair of push plates are fixedly connected to the inner wall of the top of the rotating plate.

[0016] As a further description of the above technical solution:

[0017] The push plate is externally slidably connected to the outside of the two hook plates, and the adjacent side of each pair of push plates is fixedly connected to the distant end of the two springs respectively;

As the transmission plate slides, the temperature and humidity sensor on the rotating plate unfolds, thereby expanding its sampling range. Simultaneously, it drives the square plate to slide upwards. This causes the square plate and its upper drive assembly, temperature and humidity sensor, and other components to move up and down within the support box, adjusting the height of the sampling device to accommodate temperature and humidity sampling needs at different heights.

[0037] 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.

[0038] Reference Figures 1 to 3 This utility model provides an embodiment of a smart laboratory on-site sampling device based on Internet of Things (IoT) technology, comprising a support box 1 and multiple temperature and humidity collectors 13. The support box 1 serves as the external protection and load-bearing structure for the entire sampling device. A top plate 3 is fixedly connected to the top side of the support box 1, protecting the internal components and preventing dust and debris from falling in. A square plate 4 is fixedly connected inside the support box 1, forming a horizontal support platform. A drive mechanism for subsequent components to slide up and down is fixedly connected to the top side of the square plate 4. The drive mechanism includes a cylinder 5, a common and reliable linear drive device, whose bottom side is fixedly connected to the top side of the square plate 4, with welding ensuring the connection's strength and stability. A transmission plate 6 is fixedly connected to the drive end of the cylinder 5, enabling precise linear reciprocating motion under the drive of the cylinder 5, providing power and motion conversion for the rotation of subsequent components.

[0039] Reference Figures 3 to 5The drive assembly has rotating plates 7 rotatably connected to its top four sides. The transmission plate 6 is rotatably connected to the adjacent ends of multiple rotating plates 7, allowing the linear motion of the transmission plate 6 to be converted into the rotational motion of the rotating plates 7. The bottom side of the temperature and humidity sensor 13 contacts the top side of the rotating plates 7, ensuring that the motion of the rotating plates 7 is accurately transmitted to the temperature and humidity sensor 13. A limit frame 8 is slidably connected to the outside of the rotating plates 7, precisely limiting and constraining the rotation range and trajectory of the rotating plates 7. Two push rods 9 are slidably connected to the top of the rotating plates 7, allowing the push rods 9 to slide stably due to the constraint of the rotating plates 7. A push plate 10 is fixedly connected to the adjacent side of every two push rods 9, transmitting the sliding force to the push plate 10 through the push rods 9.

[0040] Each pair of push plates 10 is externally fixedly connected to the inner wall of the top of the rotating plate 7. The rotating plate 7 restricts the stable sliding of the push plates 10. Two positioning posts 11 are internally slidably connected to each pair of push plates 10, providing precise guidance and positioning for their sliding movement. Springs 12 are sleeved on the outside of the positioning posts 11, ensuring uniform force distribution. The adjacent sides of each pair of push plates 10 are fixedly connected to the distant ends of the two springs 12. As the push plates 10 slide, they compress the springs 12, allowing them to store elastic potential energy and thus provide a counterforce to the push plates 10 for resetting. Multiple hook-shaped plates 14 are fixedly connected to the bottom of the temperature and humidity collector 13. The cooperation between the hook-shaped plates 14 and the push plates 10 enables quick installation and removal of the temperature and humidity collector 13 on the rotating plate 7. Analyzing experimental processes in a smart laboratory using IoT technology requires specific temperature and humidity environments. The temperature and humidity collector 13 can monitor the environment in real time to ensure that the experimental environment meets the requirements. In environmental monitoring experiments, long-term recording of temperature and humidity data can be used to assess the health of ecosystems. For example, in a smart laboratory using IoT technology, changes in temperature and humidity can affect the survival of wetland plants and animals. Data recording and analysis by the data logger can reveal the stability of the wetland environment, providing a basis for wetland protection. The push plate 10 is externally slidably connected to the outside of two hook-shaped plates 14, and the push plate 10 engages and fixes the hook-shaped plates 14.

[0041] Reference Figure 1 and Figure 6A limiting box 15 is slidably connected to the inner wall of the support box 1, allowing the limiting box 15 to slide stably. A base plate 2 is fixedly connected to the bottom side of the limiting box 15, providing stable bottom support for the entire sampling device. The bottom side of the support box 1 contacts the top side of the base plate 2, ensuring the structural integrity and stability of the entire device. A power assembly for driving the rotation of subsequent components is fixedly connected to the top of the limiting box 15. The power assembly includes a motor 16, which provides the drive source. The motor 16 is externally fixedly connected to the inner wall of the top of the limiting box 15 and fixed by welding, enabling the motor 16 to operate stably. A rotating shaft 17 is fixedly connected to the drive end of the motor 16, transmitting the force from the drive end of the motor 16 to subsequent components. A gear 18 is externally fixedly connected to the power assembly, serving as an intermediate component for power transmission and motion conversion.

[0042] The external shaft 17 is fixedly connected to the inner wall of the gear 18, ensuring that the power of the motor 16 can be accurately transmitted to the gear 18. A rack 19 is slidably connected to the inner wall of the limiting box 15, allowing the rack 19 to slide stably. The gear 18 and rack 19 are meshed, with the rack 19 sliding up and down due to the rotation of the gear 18. The top side of the rack 19 is fixedly connected to the bottom side of the square plate 4, allowing the movement of the rack 19 to be accurately transmitted to the square plate 4, enabling the square plate 4 to slide up and down. The limiting box 15 has an internal cavity 20, providing installation and protection space for components such as the motor 16 and gear 18. Two limiting posts 21 are fixedly connected to the external side of the limiting frame 8, restricting its rotation. Each pair of limiting posts 21 is rotatably connected to the top perimeter of the support box 1, allowing the limiting frame 8 to perform stable circular motion at the top of the support box 1.

[0043] Working principle: First, the drive cylinder 5 pushes the transmission plate 6 upward by driving its drive end, thereby pushing the rotating plate 7 to slide. Under the restriction of the limit frame 8, the rotating plate 7 converts the sliding force into the rotational force. As the transmission plate 6 slides, the temperature and humidity collector 13 on the rotating plate 7 unfolds, thereby expanding the collection range of the temperature and humidity collector 13. When installing the temperature and humidity collector 13, the two push rods 9 inside the rotating plate 7 are pressed and slid to the same side, thereby pushing the push plate 10 to slide and compress the spring 12. This allows the spring 12 to store elastic potential energy, which then applies a force in the opposite direction to the push plate 10 to reset it. As the push plate 10 slides, it slides until it is no longer engaged with the hook plate 14, at which point the temperature and humidity collector 13 can be quickly removed. Conversely, when installing the temperature and humidity collector 13, the hook plate 14 on the temperature and humidity collector 13 abuts against the push plate 10, allowing the push plate 10 to slide and compress the spring 12. This continues until the hook plate 14 slides until it is no longer abutting against the push plate 10. At this point, the spring 12 will reset and abut against the push plate 10 to lock the hook plate 14, thus completing the quick installation of the temperature and humidity collector 13 and saving time and costs.

[0044] Furthermore, the drive motor 16 drives the rotating shaft 17 to rotate, which in turn drives the gear 18 to rotate. The gear 18 drives the meshing rack 19 to slide upwards. This, in turn, drives the square plate 4 to slide upwards. Thus, the square plate 4 and the drive assembly, temperature and humidity collector 13, and other components above it move up and down within the support box 1, thereby adjusting the height of the sampling device to meet the temperature and humidity sampling requirements at different heights.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
