Description

Technical Field

[0001] The present invention belongs to the technical field of environmental monitoring equipment, and in particular relates to an ecological environment prediction device and a prediction method based on meteorological data simulation. Background Art

[0002] The carbon cycle can comprehensively reflect the response of ecosystems to climate change and the impact of human activities, and has therefore become an important part of global climate change research. Among them, the terrestrial vegetation carbon cycle is an important component of the carbon cycle, and NEP (net ecosystem productivity) is a key parameter to characterize vegetation activity. Its accurate estimation not only helps to measure the health of vegetation ecosystems, but also helps to quantitatively analyze the carbon sequestration status and potential of regional vegetation ecosystems.

[0003] When estimating NEP, it is necessary to comprehensively consider local vegetation types, soil conditions, and climatic conditions, and at the same time establish remote sensing models and soil respiration models. In combination with high-resolution remote sensing data and meteorological data, the spatiotemporal distribution pattern of NEP can be analyzed. When establishing the soil respiration model, staff are required to sample and analyze the local soil environment. In conventional technology, soil sampling usually uses a cylindrical sampling cylinder, which is inserted vertically into the ground to take cylindrical soil specimens. However, in actual implementation, as the sampling cylinder extends underground, it usually exerts downward pressure on the soil, causing the soil to settle in the vertical direction, resulting in a certain deviation between the soil column taken and reality. Especially when sampling relatively loose soil, due to the lack of constraint on the soil sample, it is easy to cause the soil layer to settle under the action of external force.

[0004] For example, a soil pollution monitoring device with patent publication number CN117288520B has been disclosed in the related art. In this patent, the soil is completely embedded in the sampling steel pipe by knocking the sampling steel pipe into the soil, ensuring that the original position of the soil at different depths does not change, thereby preventing the soil at different depths from mixing together; the vertical sampling method is adopted, which can complete soil sampling more quickly. When this device is used, it is easy to cause mutual influence between soil layers, and it is not convenient to use in areas with relatively soft soil.

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0049] like Figures 1 to 9 As shown, the ecological environment prediction device based on meteorological data simulation according to the present invention includes a drill tube 1 and a transverse extension mechanism. The drill tube 1 is used to open a sampling groove on the ground. In the present invention, the drill tube 1 is preferably a cylindrical hollow tube, which is driven by equipment or manpower to drill holes in the ground to facilitate sampling of underground soil. The transverse extension mechanism cooperates with the drill tube 1 to sample the soil on the inner wall of the sampling groove in the horizontal direction.

[0050] The lateral extension mechanism includes an extension tube 2, a lateral sampling box and a driving member;

[0051] The extension tube 2 is a hollow cylindrical structure. The extension tube 2 is detachably mounted on the bottom end of the drill tube 1. The extension tube 2 has the same shape as the drill tube 1. When sampling by horizontal extension, the drill tube 1 is taken out of the sampling slot and then the extension tube 2 is mounted under the drill tube 1 and carried and transported to the bottom of the sampling slot by the drill tube 1.

[0052] The side wall of the extension tube 2 is provided with a receiving groove 21, and the transverse sampling box is slidably installed in the receiving groove 21;

[0053] A driving member is installed in the extension tube 2, and the driving member is used to drive the transverse sampling box to sample toward the inner wall of the sampling groove.

[0054] When sampling underground soil, in order to prevent the soil sample from being vertically compressed and to prevent soils at different heights from mixing when the sampling trough is excavated, the present invention provides a transverse extension mechanism to perform transverse extension sampling on the side wall of the sampling trough to maintain the state of the soil sample;

[0055] Specifically, when sampling underground soil in a pre-selected area, the staff first uses the drill tube 1 to open a sampling groove on the ground, and then uses the drill tube 1 to transport the horizontal extension mechanism. When the transportation depth reaches the preset depth, the horizontal sampling box in the receiving groove 21 is driven with the help of a driving member, causing the horizontal sampling box to first move horizontally toward the inner wall of the sampling groove, and then reset and retract into the receiving groove 21. During the movement, the soil on the side wall of the sampling groove is collected and finally carried and transported to the ground by the drill tube 1 to complete the sampling operation.

[0056] It should be noted that, since the present invention adopts a lateral extension mechanism for soil sampling, although when the sampling groove is excavated, the vertical extension of the drill tube 1 will cause the soil on the inner wall of the sampling groove to be under pressure and to settle, but in the process of lateral extension, as the horizontal extension distance increases, the sampled soil is less affected by the extension of the drill tube 1, and since the lateral sampling box moves horizontally in the horizontal direction, the pressure level acts on the soil, and the soil is usually layered in the vertical direction. Therefore, when the lateral sampling box samples horizontally, the impact on multiple layers of soil is relatively small.

[0057] The transverse extension mechanism also includes a plurality of separators 22, which are all slidably installed in the transverse sampling box. The separators 22 are arranged at equal intervals in the vertical direction. The separators 22 are installed in the transverse sampling box and extend horizontally and transversely toward the inner wall of the sampling groove together with the transverse sampling box. The presence of multiple separators 22 separates the soil entering the transverse sampling box, further reducing the probability of mixing when sampling multiple layers of soil, especially when there are many voids in the soil. After part of the soil is cut and disturbed, small particles of soil can easily move to the voids below under the action of gravity, thereby causing the divided soil to settle in the vertical direction. The presence of the separators 22 can also utilize the separation effect to effectively reduce the mixing phenomenon caused by gravity after the soil enters the transverse sampling box. It should be noted that as the spacing between the separators 22 decreases and the thickness of the separators 22 decreases, the separators 22 can maintain the vertical stratification of the sampled soil better.

[0058] The transverse sampling box includes an end plate 23, a support column 24, a cutting piece 27 and a traction rope 28;

[0059] The end plates 23 are sheet-like structures. There are two end plates 23 and they are arranged horizontally and symmetrically. The support columns 24 are located between the end plates 23. The support columns 24 and the end plates 23 are fixedly connected. In the present invention, the end plates 23 are arranged horizontally for extending toward the inner wall of the sampling trough, while the support columns 24 are arranged vertically for connecting the two end plates 23. The support columns 24 are fixedly connected to the end of the end plates 23 away from the inner wall of the sampling trough. When the end plates 23 extend toward the inner wall of the sampling trough, the end plates 23 are gradually inserted into the soil until the support columns 24 fit the inner wall of the sampling trough.

[0060] The support column 24 is provided with a winding groove 25, in which a rotating rod 26 is rotatably mounted. One end of the cutting blade 27 is fixedly mounted on the rotating rod 26. In an initial state, the cutting blade 27 is wound and stored in the winding groove 25. In the present invention, the cutting blade 27 is composed of a sheet-like structure with a relatively small thickness, and the cutting blade 27 can be wound in the length direction. In the initial state, the cutting blade 27 is in a wound state.

[0061] A traction rope 28 is fixedly installed on the end of the cutting blade 27 away from the rotating rod 26, and a guide groove 29 is provided on the end plate 23. The traction rope 28 extends from the side of the end plate 23 away from the extension tube 2 to the guide groove 29. The traction rope 28 is connected to the driving member. The existence of the traction rope 28 is to pull the cutting blade 27. The traction rope 28 is used to pull the cutting blade 27, causing the cutting blade 27 to cut the soil.

[0062] The plurality of separators 22 are fixedly connected at one end facing the receiving slot 21 via a connecting plate, and the connecting plate is detachably fixedly connected to the supporting column 24 .

[0063] When sampling the inner wall of the sampling trough horizontally, the driving member first causes the support column 24 and the end plate 23 to move toward the inner wall of the sampling trough. At the same time, the partition plate 22 connected to the support column 24 through the connecting plate moves synchronously with the end plate 23. As the movement continues, the end plate 23 and the partition plate 22 gradually insert into the soil layer to realize vertical separation of the soil layer. When the movement distance of the end plate 23 reaches a preset value, the driving member stops driving the end plate 23 and pulls the traction rope 28 instead. Since the other end of the traction rope 28 is fixed on the cutting blade 27, and the traction rope The extension path 28 is along the periphery of the end plate 23. Therefore, when the traction rope 28 is pulled, the cutting blade 27 will be pulled to move synchronously, and the movement trajectory of the cutting blade 27 is along the outer edge of the end plate 23. As the cutting blade 27 continues to move, the soil entering the gap between the end plate 23 and the separator 22 will be cut and separated from the external soil. Finally, the cutting blade 27 will wrap the periphery of the end plate 23 and the separator 22. At this time, the driving member drives the end plate 23 again, causing the end plate 23, the separator 22 and the soil in the gap to move into the receiving groove 21 together, and be carried to the ground by the drill pipe 1 for inspection.

[0064] The present invention realizes sampling of the inner wall of the sampling trough by adopting the end plate 23 and the separator 22 that move laterally, and cooperating with the cutting blade 27 that moves along the outer edge of the end plate 23. When sampling, it is first inserted horizontally into the soil layer to isolate the soil in layers to avoid mixing of multiple layers of soil. Then, the horizontal movement of the cutting blade 27 is used to separate the isolated layered soil, thereby reducing the difficulty of removing the soil. The cutting blade 27 cooperates with the end plate 23 and the separator 22 to realize spatial restriction of the soil, which can further reduce the occurrence of soil mixing during subsequent transportation.

[0065] As a preferred embodiment of the present invention, the horizontal sampling box also includes an intercepting plate 3, which is slidably installed between two adjacent end plates 23. The intercepting plate 3 is provided with a mounting groove 31 corresponding to the separator 22. The separator 22 is installed on the intercepting plate 3 through the mounting groove 31. The mounting groove 31 passes through the intercepting plate 3. An elastic layer is installed on the inner wall of the mounting groove 31. The separator 22 is slidably installed on the intercepting plate 3 through the mounting groove 31. A limiting frame 32 is fixedly installed at the opening of the receiving groove 21. In the initial state, the intercepting plate 3 cooperates with the limiting frame 32 to close the opening of the receiving groove 21. Due to the presence of the elastic layer, there is a certain resistance when relative movement is generated between the intercepting plate 3 and the separator 22. Before extending the horizontal extension mechanism into the sampling groove, the staff manually adjusts the position of the intercepting plate 3, so that the intercepting plate 3 cooperates with the limiting frame 32 to achieve The sealing of the opening of the receiving groove 21 can reduce the probability of the soil in the sampling groove entering the receiving groove 21 by itself during transportation. Then, when the end plate 23 and the partition 22 extend into the soil layer on the inner wall of the sampling groove, under the resistance of the partition 22 and the elastic layer, the intercepting plate 3 adheres to the soil layer on the inner wall of the sampling groove, effectively reducing the phenomenon of the soil layer falling off and peeling off. As the end plate 23 and the partition 22 are continuously inserted, the intercepting plate 3 is finally brought into contact with the connecting plate, and then the cutting blade 27 cuts the soil, and under the action of the driving member, the end plate 23 and the cutting blade 27 push the soil toward the receiving groove 21. At this time, the intercepting plate 3 extends deep into the receiving groove 21 by itself, and when the horizontal sampling box is taken out again outside the ground, the cutting blade 27 cooperates with the intercepting plate 3 to wrap the outer periphery of the end plate 23 and the partition 22, thereby effectively fixing the soil sample.

[0066] The separator 22 is fixedly installed with uniformly distributed reinforcing ribs in the width direction. The reinforcing ribs are used to increase the difficulty of deformation of the separator 22. The presence of the reinforcing ribs can extend the service life of the separator 22. The distribution of the reinforcing ribs and the spatial structure of the separator 22 increases the force that can be transmitted when the separator 22 is thin, making it easier for the separator 22 to extend into the soil.

[0067] As a preferred embodiment of the present invention, the cutting blade 27 is composed of a fiber membrane and a vertical plate. The vertical plate is fixedly installed on the fiber membrane. A plurality of the vertical plates are evenly arranged along the winding direction of the fiber membrane. The traction rope 28 is fixedly connected to the first vertical plate. The cutting blade 27 is composed of the vertical plate and the fiber membrane. On the one hand, the fiber membrane composed of high-strength fiber and membrane material has high strength and is not easy to be damaged. The distribution of the vertical plates enables the cutting blade 27 to be wound. The existence of the vertical plates is used to improve the strength of the cutting blade 27. When the vertical plates move with the traction rope 28, the thin sheet-like vertical plates made of high-strength metal material can cut the soil.

[0068] As a preferred embodiment of the present invention, the driving member includes a push-pull plate 4, a transmission shaft 42, a transmission gear 43 and a winding wheel 51;

[0069] The end plate 23 facing the receiving slot 21 is fixedly mounted with a push-pull plate 4, and the push-pull plate 4 is provided with a tooth groove 41;

[0070] A transmission shaft 42 is rotatably mounted on the extension cylinder 2, and the transmission shaft 42 extends into the receiving groove 21. A transmission gear 43 is fixedly mounted on the transmission shaft 42, and the transmission gear 43 is meshed with the tooth groove 41.

[0071] The push-pull plate 4 is provided with a winding groove 5 at one end away from the end plate 23. A winding wheel 51 is rotatably installed in the winding groove 5. The top of the winding wheel 51 is designed in a gear shape. The winding wheel 51 is located at the end of the tooth groove 41. The traction rope 28 extends into the winding groove 5 through the guide groove 29, and the traction rope 28 is fixedly connected to the winding wheel 51.

[0072] A rubber wheel 52 is rotatably mounted on the extension tube 2. The rubber wheel 52 is in transmission connection with the transmission shaft 42. The rubber wheel 52 is frictionally driven by the inner cavity of the drill tube 1. The outer diameter of the rubber wheel 52 is slightly larger than the inner diameter of the drill tube 1. Therefore, when the rubber wheel 52 is inserted into the inner diameter of the drill tube 1, the rotation of the drill tube 1 can synchronously drive the rubber wheel 52 to rotate.

[0073] During the horizontal extension sampling, the drill barrel 1 drives the rubber wheel 52 to rotate, and the transmission causes the transmission shaft 42 to rotate, and the transmission shaft 42 drives the transmission gear 43, and the transmission gear 43 engages with the tooth groove 41, thereby pushing the push-pull plate 4 and the end plate 23 to move. With the linear motion of the push-pull plate 4, the transmission gear 43 gradually moves to the end of the tooth groove 41. When the transmission gear 43 is separated from the tooth groove 41, the drill barrel 1 drives the friction wheel and the transmission shaft 42 to reduce the rotation resistance, so as to convey the information that the horizontal horizontal movement of the end plate 23 is completed to the staff. At this time, the staff rotates the drill barrel 1 in the opposite direction. However, since the transmission gear 43 is separated from the tooth groove 41 at this time, the reverse rotation of the transmission gear 43 cannot drive the push-pull plate 4 to reset, and the winding wheel 51 at the end of the tooth groove 41 is driven by the transmission gear 43. When the wire wheel 51 rotates, the traction rope 28 is gradually tightened, and the traction rope 28 and the cutting blade 27 are gradually unfolded. During this process, when the cutting blade 27 is fully unfolded, the wire wheel 51 can no longer rotate, and the transmission gear 43 pushes the wire wheel 51 and the push-pull plate 4 to make a linear motion, so that the transmission gear 43 is engaged with the tooth groove 41 again. With the continuous rotation of the transmission gear 43, the horizontal sampling box is eventually reset to complete the sampling operation. After pulling the equipment to the ground and separating the drill barrel 1 from the rubber wheel 52, the staff manually rotates the rubber wheel 52 to move the horizontal sampling box out of the storage groove 21. Finally, after the staff places the horizontal sampling box horizontally, the connecting plate, intercepting plate 3 and separator 22 are disassembled to facilitate soil testing.

[0074] A method for predicting an ecological environment based on meteorological data simulation, the method comprising the following steps:

[0075] S1. Drill a sampling slot on the ground using a drill tube 1. After the sampling slot is drilled, install a transverse extension mechanism at the bottom end of the drill tube 1.

[0076] S2, the drill tube 1 carries the lateral extension mechanism to extend to the bottom of the sampling tank. After reaching the bottom, the drill tube 1 is driven to rotate, and after transmission, the rubber wheel 52, the transmission shaft 42, the driving member, and the lateral sampling box are driven in sequence;

[0077] S3. After the lateral sampling box samples the side wall of the sampling slot, the drill tube 1 is pulled to remove the lateral extension mechanism, and then the lateral extension mechanism is separated from the drill tube 1.

[0078] S4. Manually rotate the rubber wheel 52 to separate the horizontal sampling box from the extension tube 2. Then, place the horizontal sampling box horizontally, remove the intercepting plate 3 and the separator 22, and then test the soil sample.

[0079] S5. Combine soil data, topography and administrative division data, historical meteorological data, vegetation DNVI data, land cover type data, and future climate scenario data to establish an ecosystem process model to estimate future NEP.
