Description

Technical Field

[0001] This invention belongs to the field of soil gaseous water quantitative technology, specifically a soil gaseous water quantitative identification device and method. Background Technology

[0002] Early research on vadose zone water transport focused solely on liquid water due to limitations in experimental equipment and computational methods, neglecting gaseous water. However, with advancements in research and technology, the importance of gaseous water has become increasingly apparent. On one hand, related studies have deepened our understanding of the water cycle theory. The relative humidity in the vadose zone is near saturation, and the continuous conversion between gaseous and liquid water causes diurnal and seasonal variations in soil moisture content. The phase transition process also alters heat conduction and temperature distribution. On the other hand, gaseous water transport has significant impacts on engineering construction, agricultural production, and environmental protection. For example, in cold and arid regions, roadbed frost heave and cracking can occur due to gaseous water migration. During droughts, gaseous water is an important source of moisture for vegetation. However, current gaseous water resources are not being utilized rationally, mainly due to limited quantitative understanding. Gaseous water cannot be directly measured, and research relies heavily on simulation analysis. The lack of quantitative identification leads to uncertainty in subsequent research. Furthermore, existing research has not fully elucidated the changes in gaseous water flux in the root zone of vegetation and its support for root water absorption, resulting in a shallow understanding of its ecological functions. Currently, traditional soil gaseous water quantitative identification devices involve installing the identification component inside a housing, connecting the upper and lower housings together with wire, covering the housing surface with a mesh to prevent soil from entering, placing the device in a dug pit or inserting it into the soil, and then burying it with soil. After burying, water vapor in the soil passes through the pores on the housing surface, and the condensation component condenses the water vapor into water, which drips onto a high-precision balance for weighing. The electrical signal transmission component collects the data and transmits it to a data acquisition unit for easy observation by the operator. However, during the use of the above-mentioned device, especially during the fixing of the two shells, the existing technology requires the use of a lot of wire for fixing. Moreover, the wire fixing operation is extremely cumbersome. Workers need to use tools to wrap and tighten the wires one by one to ensure that each connection point is firm and reliable. This process is time-consuming and greatly reduces the fixing efficiency and the ease of device assembly. Summary of the Invention

Fixing mechanism one, which is installed on one side of the upper and lower housings; The fixing mechanism includes a threaded rod fixedly connected to the inside of the lower housing. A storage shell is threaded onto the surface of the threaded rod. Mounting shells are fixedly installed at both ends inside the storage shell. A rotating plate is rotatably connected inside the mounting shell. A gear is fixedly installed on one side of the rotating plate. Baffles are fixedly installed inside both the upper and lower housings. An insert block located inside the baffle is fixedly installed on the side of the rotating plate near the baffle. The drive component is located inside the mounting housing.

[0005] Preferably, the drive assembly includes an elastic element fixedly installed inside the mounting housing, a rack fixedly installed at one end of the elastic element, and a connecting block located outside the housing fixedly installed on one side of the rack.

[0006] Preferably, it further includes: The second fixing mechanism is disposed on the surface of the storage shell. The second fixing mechanism includes a connecting ring fixedly connected to the surface of the storage shell. Mounting plates are fixedly installed on both sides of the surface of the connecting ring. Spring airbags are fixedly installed on the side of the two mounting plates near the surface of the upper shell. A sealing shell is fixedly installed on the surface of the storage shell. A slider is slidably connected inside the sealing shell. The slider and the sealing shell are elastically connected by an elastic element. A clamping plate is fixedly installed on the side of the slider near the inside of the storage shell. The spring airbags and the sealing shell are connected by a connecting pipe.

[0007] Preferably, it further includes: A limiting component is provided on opposite sides of an upper housing and a lower housing. The limiting component includes a groove formed at the bottom end of the upper housing, and a limiting block located in the core of the groove is fixedly installed at the top end of the lower housing.

[0008] Preferably, the clamping plate has an arc-shaped design and a rough surface.

[0009] Preferably, the insert is circular, and there is a gap between the surface of the insert and the inner wall of the baffle.

[0010] Preferably, the elastic element has a telescopic rod inside, and both ends of the telescopic rod are fixedly connected to the mounting shell and the rack.

[0011] Preferably, a fixing hole is provided on one side of the mounting shell, and the surface of the connecting block is in contact with the inner wall of the fixing hole.

[0012] Preferably, one side of the mounting shell is chamfered, and the mounting shell is laterally symmetrical about the center of the storage shell.

[0013] A method for quantitative identification of soil gaseous water is as follows: S1: First, install the condenser assembly, high-precision balance, and electrical signal transmission assembly inside the upper and lower housings. Then, place the upper housing on top of the lower housing, and the limiting block smoothly enters the slide groove. Subsequently, push the lower housing... Figure 3 Moving in the direction of the arrow, the limiting block moves along the inside of the slide groove until it reaches one side of the slide groove of the T-shaped design and enters the interior of the T-shaped structure. At this time, the surface of the limiting block is in contact with the inner wall of the slide groove. By means of the friction generated by this close contact, the upper shell is initially fixed. S2: The mesh is fitted onto the surfaces of the upper and lower housings, and the opening and closing parts of the mesh are gathered together. The gathered mesh is then inserted into the storage shell. The storage shell can then be rotated and moved along the threaded surface of the threaded rod, gradually entering the interior of the upper and lower housings. The connecting block will contact the surface of the baffle and then retract into the installation shell. The retraction of the connecting block drives the rack to move and rotates the gear. The rotation of the gear causes the rotating plate and the insert to move closer to the surface of the baffle. Finally, the two inserts enter the interior of the two baffles respectively, achieving a stable fixation of the upper and lower housings. S3: At the same time, the storage shell drives the mesh part into the upper and lower shells, and at the same time drives the mounting plate and spring airbag to rotate and move. After the surface of the spring airbag comes into contact with the surface of the upper and lower shells, it is squeezed. The gas inside it passes through the connecting pipe into the sealing shell, and the air pressure increases, pushing the slider to move. During this process, the elastic element 2 is stretched. The slider drives the clamping plate to move towards the mesh surface inside the storage shell, and firmly fixes the mesh by squeezing. In addition, when the insert block enters the baffle, part of the mesh also enters, using a double fixing method to fix the mesh. S4: After fixing, put the upper and lower shells into the dug pit or insert them into the soil and bury them. After burying, the soil moisture passes through the mesh and vents into the interior of the upper shell. The condensation component condenses the moisture into water, and the high-precision balance weighs the water droplets. The electrical signal transmission component transmits the data to the data acquisition device, and the operator observes the data acquisition device to understand the soil moisture.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a rotating housing shell, which, due to its threaded connection to a threaded rod, moves along the threaded surface of the rod and enters the upper and lower housings. The housing shell drives the connecting block to move, during which the connecting block contacts the baffle surface and then retracts into the mounting shell. The connecting block drives the rack to move, and the rack presses against the elastic element. Because it meshes with the gear, it drives the gear to rotate. The gear then drives the rotating plate and the insert block to move closer to the baffle surface. The two insert blocks enter the two baffles respectively, fixing the upper and lower housings. The entire process, through rotating the housing shell, causes the connecting block to retract and drives the insert blocks into the baffles, eliminating the need for wire fixing, effectively improving fixing efficiency, and making device assembly more convenient. This invention utilizes a method of inserting a gathered mesh into a housing. The movement of the housing causes the mounting plate and spring airbag to rotate. The surface of the spring airbag contacts and is compressed against the surfaces of the upper and lower housings. The gas inside the airbag passes through a connecting pipe into the sealed housing, increasing the air pressure and pushing the slider. During this process, the elastic element is stretched, and the slider moves the clamping plate towards the mesh surface inside the housing, firmly fixing the mesh with compression. Simultaneously, when the insert block enters the baffle, part of the mesh enters as well, forming a double fixation, significantly improving the fixing effect. Finally, the housing is completely inserted into the upper and lower housings, further increasing the mesh tension and ensuring the mesh tightly adheres to the surfaces of the upper and lower housings. This effectively prevents the mesh from shifting when the device is inserted into the soil, enhancing the stability of the entire device. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 8 As shown, the present invention provides a soil gaseous water quantitative identification device, including an upper housing 100 and a lower housing 200, and further comprising: The mesh 800 is fitted inside the upper housing 100 and the lower housing 200; The identification component 300 is disposed inside the upper housing 100 and the lower housing 200. The identification component 300 includes a condensation component 301 fixedly connected inside the upper housing 100. A high-precision balance 302 and an electrical signal transmission component 303 are disposed inside the lower housing 200. A data acquisition device 304 is disposed outside the upper housing 100 and the lower housing 200. The electrical signal transmission component 303 is connected to the data acquisition device 304 via a cable. The fixing mechanism 400 is installed on one side of the upper housing 100 and the lower housing 200; The fixing mechanism 400 includes a threaded rod 401 fixedly connected to the inside of the lower housing 200. A receiving shell 402 is threadedly fitted on the surface of the threaded rod 401. Mounting shells 403 are fixedly installed at both ends inside the receiving shell 402. A rotating plate 404 is rotatably connected inside the mounting shell 403. A gear 405 is fixedly installed on one side of the rotating plate 404. A baffle 407 is fixedly installed inside both the upper housing 100 and the lower housing 200. An insert 406 located inside the baffle 407 is fixedly installed on the side of the rotating plate 404 near the baffle 407. The drive component 500 is located inside the mounting housing 403.

[0019] like Figure 5 , Figure 6 and Figure 7 As shown, the drive assembly 500 includes an elastic member 501 fixedly installed inside the mounting housing 403. A rack 502 is fixedly installed at one end of the elastic member 501, and a connecting block 503 located outside the housing 402 is fixedly installed on one side of the rack 502.

[0020] Using the above scheme: The operator installs the condenser assembly 301, the high-precision balance 302, and the electrical signal transmission assembly 303 inside the upper housing 100 and the lower housing 200, and then assembles the upper housing 100 and the lower housing 200 together. Then, the receiving shell 402 is rotated. Since the receiving shell 402 is threadedly connected to the threaded rod 401, the receiving shell 402 will move along the threads on the surface of the threaded rod 401, and then the receiving shell 402 will enter the interior of the upper housing 100 and the lower housing 200. Next, the receiving shell 402 will drive the connecting block 503 to move. During this movement... During the process, it will move against the surface of the baffle 407, and then the connecting block 503 will retract into the interior of the mounting shell 403. The connecting block 503 will drive the rack 502 to move. When the rack 502 moves, it will squeeze the elastic element 501, and the rack 502 will mesh with the gear 405. Then, when the rack 502 moves, it will drive the gear 405 to rotate. The gear 405 will drive the rotating plate 404 and the insert block 406 towards the surface of the baffle 407. Then, the two insert blocks 406 will enter the interior of the two baffles 407 respectively, thereby fixing the upper shell 100 and the lower shell 200 together. After fixing, the mesh 800 is placed over the surfaces of the upper shell 100 and lower shell 200 to prevent soil from entering the interior of the upper shell 100 and lower shell 200 during the burial process. Then, the upper shell 100 and lower shell 200 are placed into the dug pit or inserted into the soil and buried with soil. After burial, moisture in the soil will pass through the mesh 800 and the vent 305 into the interior of the upper shell 100. The top of the vent 305 is equipped with an inclined baffle to prevent rainwater from entering the interior of the upper shell 100 and lower shell 200 along the vent 305. The condensation component 301 can then condense the moisture into water, which will drip onto the surface of the high-precision balance 302. Weighing is performed, and the electrical signal transmission component 303 transmits the data to the data acquisition unit 304 for operator observation. After identification, the solenoid valve inside the high-precision balance 302 is opened. The top of the high-precision balance 302 is designed with a slope, so the water at the top of the high-precision balance 302 will enter the solenoid valve along the slope and drain to the outside of the upper housing 100 and the lower housing 200 for easy identification in the next operation. Finally, by rotating the storage shell 402, the connecting block 503 contacts the baffle 407 and retracts into the mounting shell 403. Then, the insert block 406 is driven into the baffle 407, thereby fixing the upper housing 100 and the lower housing 200 together, avoiding the use of wire for fixing and improving fixing efficiency.

[0021] like Figure 8 As shown, it also includes: The second fixing mechanism 600 is disposed on the surface of the storage shell 402. The second fixing mechanism 600 includes a connecting ring 601 fixedly connected to the surface of the storage shell 402. Mounting plates 602 are fixedly installed on both sides of the surface of the connecting ring 601. Spring airbags 603 are fixedly installed on the side of the two mounting plates 602 near the surface of the upper shell 100. A sealing shell 604 is fixedly installed on the surface of the storage shell 402. A slider 605 is slidably connected inside the sealing shell 604. The slider 605 and the sealing shell 604 are elastically connected by an elastic element 606. A clamping plate 607 is fixedly installed on the side of the slider 605 near the inside of the storage shell 402. The spring airbag 603 and the sealing shell 604 are connected by a connecting pipe 608.

[0022] Using the above solution: Through the design of the fixing mechanism 600, after the mesh 800 is fitted inside the upper housing 100 and the lower housing 200, the opening and closing parts of the mesh 800 can be gathered together, and the gathered mesh 800 can be inserted into the storage shell 402. Then, the storage shell 402 can be rotated to move it. During the rotation of the storage shell 402, the storage shell 402 will drive a part of the mesh 800 into the upper housing 100 and the lower housing 200. The storage shell 402 will also drive the mounting plate 602 and the spring airbag 603 to rotate and move. Then, the surface of the spring airbag 603 will come into contact with the surfaces of the upper housing 100 and the lower housing 200, and the spring airbag 603 will be compressed. Then, the gas inside the spring airbag 603 will pass through the connecting pipe 608 into the sealing shell 604. With the injection of gas, the air pressure inside the sealing shell 604 increases, which will push the slider 605. During the movement of slider 605, elastic element 606 is stretched, and slider 605 drives clamping plate 607 to move towards the surface of mesh 800 inside housing 402. Subsequently, slider 605 drives clamping plate 607 to move towards the surface of mesh 800 inside housing 402, using compression to firmly fix mesh 800 inside housing 402. In addition, during the process of inserting block 406 into baffle 407, part of mesh 800 will also enter baffle 407. This double fixing method greatly improves the fixing effect. Finally, housing 402 is completely inserted into upper housing 100 and lower housing 200, further increasing the tension of mesh 800, so that mesh 800 can tightly adhere to the surface of upper housing 100 and lower housing 200, preventing the position of mesh 800 from shifting during insertion into the soil, and improving the stability of the entire device.

[0023] like Figure 3 As shown, it also includes: The limiting component 700 is located on the opposite side of the upper housing 100 and the lower housing 200. The limiting component 700 includes a groove 701 formed at the bottom of the upper housing 100, and a limiting block 702 located in the core of the groove 701 is fixedly installed at the top of the lower housing 200.

[0024] Using the above solution: Through the design of the limiting component 700, during the process of placing the upper housing 100 on top of the lower housing 200, the limiting block 702 will enter the slide groove 701, and then the lower housing 200 can be pushed to press down. Figure 3 Move in the direction of the arrow, and then the limiting block 702 will move along the inside of the slide groove 701. Then the limiting block 702 will move to one side of the T-shaped slide groove 701 and enter the interior of the T-shaped limiting block 702. Then the surface of the limiting block 702 will fit against the inner wall of the slide groove 701, thereby initially fixing the upper housing 100.

[0025] like Figure 8 As shown, the clamping plate 607 has an arc-shaped design and a rough surface.

[0026] The above solution is adopted: through the design of the clamp 607, since the clamp 607 is arc-shaped and the surface of the clamp 607 is rough, the friction between the clamp and the mesh 800 can be increased, thereby improving its fixing effect.

[0027] like Figure 7 As shown, the insert 406 is circular, and there is a gap between the surface of the insert 406 and the inner wall of the baffle 407. The elastic element 501 is equipped with a telescopic rod, and both ends of the telescopic rod are fixedly connected to the mounting shell 403 and the rack 502.

[0028] The above solution employs the following: The design of the insert 406, being circular, reduces friction with the mesh 800, preventing damage to the mesh 800 when it is inserted into the baffle 407. Furthermore, a gap exists between the surface of the insert 406 and the inner wall of the baffle 407, facilitating the mesh 800's entry into the baffle 407. The design of the elastic element 501, with its internal telescopic rod, extends during the stretching of the mounting housing 403, limiting the movement direction of the rack 502 while simultaneously restricting the elastic element 501.

[0029] like Figure 6 and Figure 7 As shown, a fixing hole is provided on one side of the mounting shell 403, and the surface of the connecting block 503 fits against the inner wall of the fixing hole. One side of the mounting shell 403 is chamfered, and the mounting shell 403 is symmetrical about the center of the storage shell 402.

[0030] The above solution is adopted as follows: Through the design of the mounting shell 403 and the connecting block 503, since a fixing hole is opened on one side of the mounting shell 403, the connecting block 503 will slide inside the fixing hole. Since the surface of the connecting block 503 fits against the inner wall of the fixing hole, the connecting block 503 can be limited. Through the design of the mounting shell 403, since the mounting shell 403 is chamfered, the resistance between the mounting shell 403 and the mesh 800 can be reduced during the insertion of the mesh 800, thus preventing the mounting shell 403 from blocking the entry of the mesh 800.

[0031] like Figures 1 to 8 As shown, a method for quantitative identification of soil gaseous water is as follows: S1: First, install the condenser assembly 301, the high-precision balance 302, and the electrical signal transmission assembly 303 inside the upper housing 100 and the lower housing 200. Then, place the upper housing 100 on top of the lower housing 200, and the limiting block 702 smoothly enters the slide groove 701. Subsequently, push the lower housing 200 to press... Figure 3 Moving in the direction of the arrow, during this process, the limiting block 702 moves along the inside of the slide groove 701 until it reaches one side of the slide groove 701 with the T-shaped design and enters the interior of the T-shaped structure. At this time, the surface of the limiting block 702 is in contact with the inner wall of the slide groove 701. By means of the friction generated by this close contact, the upper shell 100 is initially fixed. S2: The mesh 800 is fitted onto the surfaces of the upper housing 100 and the lower housing 200, and the opening and closing parts of the mesh 800 are gathered together. The gathered mesh 800 is then inserted into the storage shell 402. The storage shell 402 can then be rotated and moved along the threaded surface of the threaded rod 401, gradually entering the interior of the upper housing 100 and the lower housing 200. The connecting block 503 will contact the surface of the baffle 407 and then retract into the interior of the mounting shell 403. The retraction of the connecting block 503 drives the rack 502 to move and drives the gear 405 to rotate. The rotation of the gear 405 causes the rotating plate 404 and the insert 406 to move closer to the surface of the baffle 407. Finally, the two inserts 406 enter the interiors of the two baffles 407 respectively, thus achieving a stable fixation of the upper housing 100 and the lower housing 200. S3: At the same time, the storage shell 402 drives the mesh 800 to partially enter the upper shell 100 and lower shell 200, and at the same time drives the mounting plate 602 and spring airbag 603 to rotate and move. After the surface of the spring airbag 603 contacts the surface of the upper shell 100 and lower shell 200, it is squeezed. The gas inside it passes through the connecting pipe 608 and enters the sealing shell 604. The increased air pressure pushes the slider 605 to move. During this process, the elastic element 606 is stretched. The slider 605 drives the clamping plate 607 to move towards the surface of the mesh 800 in the storage shell 402, and firmly fixes the mesh 800 by compression. In addition, when the insert block 406 enters the baffle 407, part of the mesh 800 also enters. The mesh 800 is fixed by a double fixing method. S4: After fixing, put the upper shell 100 and the lower shell 200 into the dug pit or insert them into the soil and bury them. After burying, the soil moisture passes through the mesh 800 and the vent 305 and enters the interior of the upper shell 100. The condensation component 301 condenses the moisture into water, and the high-precision balance 302 weighs the water droplets. The electrical signal transmission component 303 transmits the data to the data acquisition device 304. The operator observes the data acquisition device 304 to understand the soil moisture.
