Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-9 The experimental device for warming forest soil shown includes an infrared temperature sensor probe 1. One end of the infrared temperature sensor probe 1 is fixedly connected to a data cable 2. The end of the data cable 2 away from the infrared temperature sensor probe 1 is fixedly connected to an infrared temperature measuring instrument host 3. A vacuum heat insulation cover 4 is fitted over the infrared temperature sensor probe 1. The vacuum heat insulation cover 4 can effectively isolate external heat radiation and electromagnetic interference. Both ends of the vacuum heat insulation cover 4 are provided with disassembly and assembly mechanisms 5. The disassembly and assembly mechanisms 5 have the function of installing and disassembling the vacuum heat insulation cover 4. One of the disassembly and assembly mechanisms 5 is provided with a distance adjustment mechanism 6. The distance adjustment mechanism 6 can adjust the distance between the soil and the infrared temperature sensor probe 1. The bottom of the infrared temperature measuring instrument host 3 is provided with a wearing mechanism 7. The wearing mechanism 7 facilitates the wearing of the infrared temperature measuring instrument host 3. The purpose of soil warming experiments is to simulate and study the impact of global warming on ecosystems. The specific experimental setup involves laying a layer of parallel and evenly distributed heating cables 10 centimeters below the soil surface in each sample plot to ensure a uniform temperature increase across the entire plot. Simultaneously, the area around the cables is backfilled with the original soil to maintain the original soil structure and environmental conditions. The heating cables convert electrical energy into heat energy. Specifically, when current passes through a resistive material (such as a nickel-chromium alloy wire), the electrical energy is converted into heat energy due to the resistance. This process follows Joule's law, which states that the heat Q generated is proportional to the square of the current I², the resistance R, and the energizing time t, as expressed in the formula Q = I²Rt. The generated heat is transferred from the heating cable to the surrounding soil through thermal conduction, with heat flowing from the high-temperature area (heating cable) to the low-temperature area (surrounding soil) until thermal equilibrium is reached. To conduct this experiment, an infrared temperature sensor probe 1 is needed to detect the ambient temperature and feed the data back to the control system. The system precisely controls the soil temperature by adjusting the current and energizing time of the heating cable. Therefore, the infrared temperature sensor probe 1 is one of the essential experimental devices for timely adjustment of heating power and maintenance of the set temperature in forest soil warming experiments.

[0023] The disassembly / assembly mechanism 5 includes fixing rings 501, which provide an installation position. The inner sides of two fixing rings 501 are respectively fixedly connected to the outer ends of the vacuum heat insulation cover 4. Multiple mounting seats 502 are fixedly connected to both outer ends of the vacuum heat insulation cover 4, providing installation space. Mounting claws 503 are rotatably connected to the inner sides of each mounting seat 502. A pull plate 504 is fixedly connected to the outer side of the mounting claws 503. Pulling the pull plate 504 causes the mounting claws 503 to rotate. A push-pull rod 505 is rotatably connected to the inner side of the pull plate 504. The push-pull rod 505 can push the pull plate 504, causing the mounting claws 503 to engage with the end of the infrared temperature sensor probe 1, thus completing the installation of the vacuum heat insulation cover 4. Alternatively, the push-pull rod 505 can be used to pull the pull plate 504, causing the mounting claws 503 to open, thereby enabling... The vacuum heat shield 4 is slidable into the outside of the infrared temperature sensor probe 1. Sliding rings 506 are slidably connected to both ends of the vacuum heat shield 4. The sliding rings 506 provide the installation position. The ends of multiple push-pull rods 505 away from the pull plate 504 are respectively rotatably connected to the side of the two sliding rings 506 near the fixed ring 501. The outside of the sliding ring 506 is fixedly connected to the finger sleeve 507. The inside of the finger sleeve 507 is covered with a protective sleeve. The protective sleeve can protect the operator's fingers from being scratched. The two ends of the vacuum heat shield 4 are covered with reset springs 508. The reset springs 508 can drive the sliding ring 506 to move towards the fixed ring 501. One end of the reset spring 508 is fixedly connected to the end of the sliding ring 506 near the mounting base 502, and the other end of the reset spring 508 is fixedly connected to the end of the fixed ring 501 near the sliding ring 506. When installing the vacuum heat shield 4, first insert two fingers into the finger sleeve 507 and pull the finger sleeve 507 towards the center. This will move the sliding ring 506 towards the center, which will then stretch the return spring 508 and pull the push-pull rod 505 towards the center. The push-pull rod 505 will then rotate the pulling plate 504 towards the center of the vacuum heat shield 4, causing the mounting claw 503 to rotate towards the center and open. At this point, the vacuum heat shield 4 is placed over the infrared temperature sensor probe 1. Then, the sliding ring 506 is released. When the reset spring 508 is pulled, the sliding ring 506 slides towards the fixed ring 501, thereby allowing the push-pull rod 505 to push the pull plate 504 to rotate away from the center of the vacuum heat shield 4. This, in turn, causes the mounting claw 503 to rotate towards the center, and allows the mounting claw 503 to engage with the end of the infrared temperature sensor probe 1, thus completing the installation of the vacuum heat shield 4. When removing the vacuum heat shield 4, the finger sleeve 507 is pulled towards the center, causing the mounting claw 503 to open. At this time, the vacuum heat shield 4 can be slid out from the outside of the infrared temperature sensor probe 1.

[0024] The distance adjustment mechanism 6 includes multiple mounting cylinders 601, which provide installation space. The exteriors of the multiple mounting cylinders 601 are respectively fixedly connected to the exteriors of two fixing rings 501. A limiting sliding piece 602 is slidably connected inside the mounting cylinder 601, serving a limiting function. One end of the limiting sliding piece 602 is fixedly connected to a connecting movable rod 603, which can slide out of the interior of the mounting cylinder 601, thereby increasing the distance from the infrared output end of the infrared temperature sensor probe 1 to the forest soil. A return spring 604 is installed inside the mounting cylinder 601. Spring 604 can push the limiting sliding piece 602 to reset. Two fixed mounting bridges 605 are fixedly connected to the outside of the four mounting cylinders 601. The fixed mounting bridges 605 provide the mounting position. A mounting ring 606 is fixedly connected to the outside of the fixed mounting bridges 605, providing the mounting position. A fixed mounting rod 607 is fixedly connected to the inside of the mounting ring 606, providing the mounting position. A rotating connecting sleeve 608 is rotatably connected to the outside of the fixed mounting rod 607, serving a connecting function. A locking curved plate 609 is fixedly connected to the outside of the rotating connecting sleeve 608. The connecting sleeve 608 has a return torsion spring 610 inside, which can drive the rotating connecting sleeve 608 to return to its original position. Two mounting bridges 611 are fixedly connected to the outside of the four connecting movable rods 603. The mounting bridges 611 provide the installation position and connection conditions. A sliding locking rod 612 is fixedly connected to the outside of the mounting bridges 611, and the sliding locking rod 612 is slidably connected inside the mounting ring 606. An elastic pull rod 613 is fixedly connected between the outer walls of the two locking curved plates 609, and the elastic pull rod 613 can connect the two locking curved plates 609. A return spring 604 is sleeved on the connecting movable... Outside of rod 603, return torsion spring 610 is sleeved on the outside of fixed mounting rod 607. Multiple connecting movable rods 603 are fixedly connected by a cooperating ring 614. One end of return spring 604 is fixedly connected to the inside of mounting cylinder 601, and the other end of return spring 604 is fixedly connected to one end of limiting sliding plate 602. One end of return torsion spring 610 is fixedly connected to the inside of rotating connecting sleeve 608, and the other end of return torsion spring 610 is fixedly connected to the outside of fixed mounting rod 607. Positioning curved plate 609 is set inside mounting ring 606, and positioning curved plate 609 engages with the outside of sliding positioning rod 612. When increasing the distance between the infrared emitter of the infrared temperature sensor probe 1 and the forest soil, the elastic rod 613 is pulled away from the vacuum insulation cover 4, which causes the locking plate 609 to rotate away from the vacuum insulation cover 4. At this time, the inner side of the locking plate 609 is released from the outer side of the sliding locking rod 612, which pushes the sliding locking rod 612 away from the infrared temperature sensor probe 1. Then, through the installation of the connecting bridge 611, the connecting movable rod 603 and the limiting sliding piece 602 are moved away from the infrared temperature sensor probe 1. The limiting sliding piece 602 compresses the return spring 604, and the cooperating ring 614 drives the other connecting movable rods 603 to move away from the infrared temperature sensor probe 1. After the distance is adjusted, the elastic rod 613 is released. At this time, under the reaction force of the return torsion spring 610, the sliding rod 603 can be moved away from the infrared temperature sensor probe 1. The rotating connecting sleeve 608 rotates away from the elastic pull rod 613, which in turn drives the locking plate 609 to rotate, causing the locking plate 609 to re-engage with the outer wall of the sliding locking rod 612. This prevents the connecting movable rod 603 from resetting under the action of the return spring 604, thus completing the distance locking after adjustment. When the temperature detection is completed, or when it is necessary to readjust the distance from the output end of the infrared temperature sensor probe 1 to the soil, the elastic pull rod 613 is pulled again to release the locking plate 609 from the sliding locking rod 612. Then, under the elastic action of the return spring 604, the limiting sliding piece 602 moves towards the center of the vacuum insulation cover 4, which in turn drives more of the connecting movable rod 603 into the interior of the mounting cylinder 601. The cooperating ring 614 is pulled again or the sliding locking rod 612 is pushed to complete the distance from the forest soil to the output end of the infrared temperature sensor probe 1.

[0025] The wearing mechanism 7 includes a mounting base 701, which provides an installation position. The top of the mounting base 701 is fixedly connected to the bottom of the infrared temperature measuring instrument main unit 3. Fixed connecting rods 702 are fixedly connected to the inner sides of both ends of the mounting base 701, which provides the position. A rotating sleeve 703 is rotatably connected to the outside of the fixed connecting rod 702. The rotating sleeve 703 has a connecting function. A wearing torsion spring 705 is provided inside the rotating sleeve 703. A wearing rotating plate 704 is fixedly connected to the outside of the rotating sleeve 703. One end of the wearing torsion spring 705 is fixedly connected to the inside of the rotating sleeve 703, and the other end of the wearing torsion spring 705 is fixedly connected to the outside of the fixed connecting rod 702. The wearing torsion spring 705 is sleeved on the outside of the fixed connecting rod 702. A rubber pad is provided on the inner side of the wearing rotating plate 704.

[0026] Working principle: When installing the vacuum heat shield 4, first insert two fingers into the finger sleeve 507 and pull the finger sleeve 507 towards the center. This will cause the sliding ring 506 to move towards the center, which will then stretch the return spring 508 and pull the push-pull rod 505 towards the center. The push-pull rod 505 will then rotate the pull plate 504 towards the center of the vacuum heat shield 4, causing the mounting claw 503 to rotate towards the center and open. At this point, the vacuum heat shield 4 is placed over the infrared temperature sensor probe 1. Then, the sliding ring 506 is released. 6. When the reset spring 508 is pulled, the sliding ring 506 is driven to slide towards the fixed ring 501, so that the push-pull rod 505 can push the pull plate 504 to rotate away from the center of the vacuum heat shield 4, which in turn drives the mounting claw 503 to rotate towards the center, and the mounting claw 503 can engage with the end of the infrared temperature sensor probe 1, thus completing the installation of the vacuum heat shield 4. When removing the vacuum heat shield 4, the finger sleeve 507 is pulled towards the center, and the mounting claw 503 is opened, so that the vacuum heat shield 4 can slide out from the outside of the infrared temperature sensor probe 1. When increasing the distance between the infrared emitter of the infrared temperature sensor probe 1 and the forest soil, the elastic rod 613 is pulled away from the vacuum insulation cover 4, which causes the locking plate 609 to rotate away from the vacuum insulation cover 4. At this time, the inner side of the locking plate 609 is released from the outer side of the sliding locking rod 612, which pushes the sliding locking rod 612 away from the infrared temperature sensor probe 1. Then, through the installation of the connecting bridge 611, the connecting movable rod 603 and the limiting sliding piece 602 are moved away from the infrared temperature sensor probe 1. The limiting sliding piece 602 compresses the return spring 604, and the cooperating ring 614 drives the other connecting movable rods 603 to move away from the infrared temperature sensor probe 1. After the distance is adjusted, the elastic rod 613 is released. At this time, under the reaction force of the return torsion spring 610, the sliding rod 603 can be moved away from the infrared temperature sensor probe 1. The rotating connecting sleeve 608 rotates away from the elastic pull rod 613, which in turn drives the locking plate 609 to rotate, so that the locking plate 609 re-engages with the outer wall of the sliding locking rod 612, thereby preventing the connecting movable rod 603 from resetting under the action of the return spring 604. At this time, the distance is locked after adjustment. When the temperature detection is completed, or when it is necessary to readjust the distance from the output end of the infrared temperature sensor probe 1 to the soil, the elastic pull rod 613 is pulled again to release the locking plate 609 from the sliding locking rod 612. Then, under the elastic action of the return spring 604, the limiting sliding piece 602 moves towards the middle of the vacuum insulation cover 4, which in turn drives more of the connecting movable rod 603 into the interior of the mounting cylinder 601. The cooperating ring 614 is pulled again or the sliding locking rod 612 is pushed to complete the distance from the forest soil to the output end of the infrared temperature sensor probe 1. When the infrared temperature measuring instrument main unit 3 is inconvenient to hold, the wearing rotating plate 704 can be opened outwards, which will drive the rotating sleeve 703 to rotate and compress the wearing torsion spring 705. At this time, the two wearing rotating plates 704 are placed outside the operator's arm. When the wearing rotating plates 704 are released, the rotating sleeve 703 is reset under the reaction force of the wearing torsion spring 705, which in turn drives the wearing rotating plates 704 to reset. This allows the two wearing rotating plates 704 to be clamped on the arm, thus completing the wearing of the infrared temperature measuring instrument main unit 3. This makes it convenient to use when it is inconvenient to hold the infrared temperature measuring instrument main unit 3, improving the practicality of the infrared temperature measuring instrument main unit 3.
