Description

Technical Field

[0001] This invention relates to the field of pit mud detection technology, and in particular to a pit mud structure detection device and a pit mud structure detection method. Background Technology

[0002] As the base material for the fermentation of strong-aroma baijiu, cellar mud develops a complex microbial structure during long-term cultivation, providing a favorable growth environment for various microorganisms. To optimize the microbial environment in the fermentation pits, it is necessary to analyze and test the structure of the cellar mud; among these analyses, the porosity measurement of the cellar mud is an important aspect of this process.

[0003] Common methods for determining porosity include the ring sampler method and the hydrostatic bottle method. The ring sampler method uses a ring sampler of known volume to collect undisturbed soil, dries it, measures the volume of soil particles, and then calculates the pore volume and porosity using a formula. Its advantages are its intuitiveness and low cost. The hydrostatic bottle method measures the specific gravity and bulk density of soil particles, indirectly calculating porosity using a formula. Its advantage is also its simple equipment. However, both the ring sampler method and the hydrostatic bottle method have significant drawbacks. Firstly, both methods require destructive treatment of the soil sample before testing, which can damage the sample's structure and lead to errors in the results. Secondly, both methods have relatively low accuracy, further increasing the risk of errors in the test results.

[0004] Furthermore, when using sampling tubes or sampling boxes to sample and test pit mud, the mud is in a soft state at certain times, such as during the initial use of the pit or after a long period of brewing. Due to the soft nature of the mud, frequent movement during the sampling and placement at the testing location can easily cause deformation of the mud sample. This deformation can lead to errors in the test results and affect the accuracy of the testing. Summary of the Invention

The control parts abut against the corresponding force-receiving parts so that the rotation of the control parts drives the force-receiving parts to rotate the valve body.

[0010] As an improvement to the above solution, it also includes multiple movable parts that are movably arranged along the moving direction of the lifting platform. Each movable part corresponds to a blocking part and is used to abut against the corresponding blocking part. The movable part is configured to include a first state and a second state. When the movable part is in the first state, it moves away from the bottom wall to drive the petals to rotate so that the petals close relative to each other, and the control part abuts against the force-bearing part. When the movable part is in the second state, it moves towards the bottom wall to drive the petals to rotate so that the petals close relative to each other, and the control part abuts against the movable part.

[0011] As an improvement to the above solution: the receiving component further includes a guide groove, a rotating part, and a flexible drive part; both the guide groove and the rotating part are disposed on the moving part, the guide groove is located between the rotating part and the control part, and the end of the guide groove near the control part has a straight section; the flexible drive part is disposed in the guide groove, and the flexible drive part includes multiple drive units, which are rotatably connected, and each pair of adjacent drive units is provided with a shaft hole, the cross-section of the opposite ends of the two shaft holes is polygonal, the shaft hole is provided with a shaft body, the shaft body is disposed through the shaft hole, and the shaft body includes a limiting section, the cross-section of the limiting section is adapted to the polygonal end of the shaft hole; one end of the flexible drive part is rotatably connected to the rotating part, and the other end of the flexible drive part is connected to the control part; when the drive unit enters the straight section of the guide groove, the limiting section of the shaft body is disposed in the polygonal end of the two shaft holes.

[0014] This invention also discloses a method for detecting the structure of pit mud, employing the pit mud structure detection device described above. The detection component is an X-ray scanning device, with an emitting end for emitting X-rays and a receiving end for receiving X-rays. A pit mud sample is selected and placed on a receiving component, positioning the sample within the detection area of ​​the X-ray scanning device. The sample is then scanned using the X-ray scanning device to obtain a 3D image of its internal structure, acquiring the pore structure parameters. The obtained 3D image and pore structure parameters are then used to analyze the pit mud sample.

[0015] As an improvement to the above scheme, the pore structure parameters of the pit mud sample include soil porosity, pore compactness, connectivity, fractal dimension, and anisotropy.

[0016] The beneficial effects of this invention are: 1. This invention uses a pit mud structure detection device to test pit mud samples after sampling. After pit mud sampling, the pit mud sample can be directly placed in the receiving component, reducing the risk of pit mud collision and deformation during pit mud movement. The receiving component of this invention can expose the pit mud sample placed on the bottom wall by removing the cover and rotating the petal to separate it. During this process, the cover and petal will not directly contact the pit mud sample, and there is no need to move the pit mud sample, thereby effectively reducing the risk of pit mud sample deformation due to contact during the testing process.

[0017] 2. This invention uses X-ray scanning equipment to scan the pit mud sample and reconstructs the pore structure in three dimensions through grayscale images, thereby accurately obtaining the internal structure of the pit mud sample and improving the accuracy of the detection and analysis of the pit mud sample; and by observing the information of each cross section inside the pit mud sample, 2D and 3D analysis of the pit mud sample is performed, making the detection and analysis process more intuitive and convenient, and effectively improving the efficiency of detection and analysis.

Detailed Implementation

[0021] To facilitate understanding of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of this invention, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0023] like Figure 1 As shown, the silt structure testing device disclosed in this application includes a placement component and a testing component. The placement component includes a lifting platform 5, which is equipped with a receiving component 7. The testing component includes a base 1, a rotating seat 2, and a testing component. The rotating seat 2 is rotatably connected to the base 1, and its rotation axis is parallel to the movement direction of the lifting platform 5. The testing component is disposed on the rotating seat 2 and includes an emitting end 3 and a receiving end 4, which are arranged opposite to each other. The object to be tested is disposed between the emitting end 3 and the receiving end 4. The lifting platform 5 can be raised and lowered vertically, and the rotation axis of the rotating seat 2 can be parallel to the vertical direction. The emitting end 3 is used to emit X-rays, and the receiving end 4 is used to receive X-rays. The emitting end 3 and the receiving end 4 are technically mature products in the prior art, and their structure and working principle are well known to those skilled in the art, and will not be described in detail here. When performing testing work, the silt structure testing device disclosed in this application needs to be set up in a radiation shielding room to ensure that X-ray protection meets the standards.

[0024] When the rotating seat 2 rotates, the detection component can scan the pit mud sample from different angles. The sample is placed on the lifting platform 5, which moves during scanning, allowing the detection component to scan different sections of the pit mud sample to form a 3D image. The receiving component 7 is used to hold the pit mud sample to be tested. After sampling, the pit mud sample can be placed in the receiving component 7, reducing the risk of deformation due to collisions with external objects during the movement of the pit mud.

[0025] like Figure 1 As shown, a positioning ring 8 can be fixedly installed on the lifting platform 5. The positioning ring 8 is located below the receiving component 7 and the position of the receiving component 7 is positioned by the positioning ring 8.

[0026] like Figure 1 As shown, in some embodiments, the placement assembly further includes multiple lifting components 6, each lifting component 6 having a lifting end connected to the lifting platform 5. The lifting component 6 can be a hydraulic cylinder or an electric actuator; the structure and working principle of hydraulic cylinders and electric actuators are well known to those skilled in the art. The moving rod of the hydraulic cylinder or electric actuator forms the lifting end, enabling the lifting platform 5 to rise and fall.

[0027] like Figures 2 to 4 As shown, in some embodiments, the receiving component 7 includes a bottom wall 11, a plurality of valves 10, and a cover 9. The bottom wall 11 is used to place the object to be detected. The valves 10 are rotatable structures, and the plurality of valves 10 are arranged circumferentially around the bottom wall 11. The plurality of valves 10 form a peripheral wall on the outer side of the bottom wall 11, and the cover 9 is disposed on the top of the peripheral wall. When the plate 10 is rotated to close the plurality of valves 10, the bottom wall 11, the plurality of valves 10, and the cover 9 form a closed chamber.

[0028] In existing technologies, when sampling and testing pit mud using common encapsulation structures such as sampling tubes or sampling boxes, the pit mud sample needs to be removed from the encapsulation structure during testing. This can easily lead to contact with the pit mud sample, potentially causing interference. Specifically, when the pit mud sample is touched, it may deform. However, when using the pit mud structure testing device disclosed in this application to test pit mud, the cover 9 is removed, and the petals 10 are rotated to separate the multiple petals 10 relative to each other. At this time, the pit mud sample placed on the bottom wall 11 can be exposed. During this process, the cover 9 and petals 10 do not come into contact with the pit mud sample, and there is no need to move the pit mud sample on the bottom wall 11, reducing the risk of contact with the pit mud sample and causing deformation. Furthermore, rotating the petals 10 can fully open the bottom wall 11, allowing the pit mud sample to be fully exposed.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, the valve body 10 is separated by its rotation axis. The valve body 10 includes a force-receiving part 15 and a blocking part 14, and the rotation axis of the valve body 10 is perpendicular to the lifting direction of the lifting platform 5. The receiving assembly 7 also includes a moving part 16 and multiple control parts 17; the moving part 16 is movably connected to the bottom wall 11 along the lifting direction of the lifting platform 5. The control parts 17 are rotatably connected to the moving part 16, and their rotation axis extends along the lifting direction of the lifting platform 5. The control parts 17 are configured to abut against the force-receiving part 15 to drive the valve body 10 to rotate. The lifting direction of the lifting platform 5 is... Figure 3 and Figure 4 The direction of the Z-axis shown is vertical when the housing component 7 is installed on the lifting platform 5.

[0030] like Figure 3 and Figure 4 As shown, the force-bearing portion 15 of the petal 10 is located near the center of the bottom wall 11, and the shielding portion 14 of the petal 10 forms the peripheral wall of the petal 10. The control portion 17 can move from top to bottom to apply pressure to the force-bearing portion 15. When the control portion 17 rotates, it can expand or contract relative to the moving portion 16. When the control portion 17 is adjusted to the appropriate position, it can contact the force-bearing portion 15. When the control portion 17 applies force to the force-bearing portion 15, the petal 10 can close, and the mud sample can be protected within the chamber formed by the receiving component 7. Conversely, when the control portion 17 no longer contacts the force-bearing portion 15, the shielding portion 14 of the petal 10 can separate, allowing the mud sample to be exposed.

[0031] Furthermore, the bottom wall 11 may be provided with a locking structure, which can be used to unlock or lock the position of the moving part 16. There are many mature locking structures in the prior art, and those skilled in the art can choose the appropriate type. In the technical solution of this application, it will not be described in detail here.

[0032] like Figure 3 and Figure 4 As shown, in some embodiments, the bottom wall 11 is movably provided with a movable part 18 along the lifting direction of the lifting platform 5, and the movable part 18 is used to abut against the blocking part 14. The moving part 16 is configured to include a first state and a second state; when the moving part 16 is in the first state, the moving part 16 moves away from the bottom wall 11 to drive the plurality of petals 10 to close, and the control part 17 abuts against the force receiving part 15; when the moving part 16 is in the second state, the moving part 16 moves towards the bottom wall 11 to drive the plurality of petals 10 to close, and the control part 17 abuts against the movable part 18. The movable part 18 can abut against the bottom of the blocking part 14. Specifically, when the moving part 16 is in the first state, the moving part 16 can move downward, and the moving part 16 drives the control part 17 to apply force to the force receiving part 15, so that the petals 10 can close. When the moving part 16 is in the second state, the moving part 16 can move upward, and the moving part 16 drives the control part 17 to apply force to the blocking part, so that the petal 10 can close.

[0033] During transportation, the receiving component 7 can be fixed in two ways: suspension or clamping. The first and second states of the moving part 16 ensure that the receiving component 7 improves the sealing effect of the petals 10 under different fixing methods, thus enhancing the protection of the pit mud sample during transportation. Specifically, when the moving part 16 is in the first state, the receiving component 7 can be fixed under pressure. The moving part 16 can partially extend out of the cover 9. When fixing the receiving component 7, it can be fixed by clamping the bottom wall 11 and the cover 9. At this time, the moving part 16 can bear force, and the control part 17 can remain against the force-bearing part 15, thereby ensuring that the multiple petals 10 remain in a closed state at all times. When the moving part 16 is in the second state, the receiving component 7 can be fixed by suspension, that is, the receiving component 7 is in a suspended state during the movement. The part of the moving part 16 that extends out of the cover 9 can be provided with a hanging ring as a suspension end. At this time, under the gravity of the receiving component 7 itself, the control part 17 can apply force to the moving part 18. The moving part 18 acts on the blocking part 14, so that the multiple petals 10 can be in a closed state.

[0034] like Figure 5As shown, in some embodiments, the receiving component 7 further includes a guide groove 20, a rotating part 19, and a flexible driving part. The guide groove 20 is disposed on the moving part 16, the rotating part 19 is disposed on the moving part 16, and the guide groove 20 is disposed between the rotating part 19 and the control part 17. The side of the guide groove 20 closest to the control part 17 is a straight segment. The flexible driving part is disposed on the guide groove 20, and the guide groove 20 serves to guide the flexible driving part. The flexible drive unit includes multiple drive units 21, which are rotatably connected in sequence. Each pair of adjacent drive units 21 has a shaft hole, and the cross-section of the opposite ends of the two shaft holes is polygonal. A shaft body 22 is provided in each shaft hole, and the shaft body 22 passes through the shaft hole. The shaft body 22 includes a limiting section 27, the cross-section of which is adapted to the polygonal end of the shaft hole. One end of the flexible drive unit is rotatably connected to the rotating part 19, and the other end is connected to the control part 17. The flexible drive unit is configured such that when the drive unit 21 enters a straight section, the limiting section 27 of the shaft body 22 is located within the polygonal end of the two shaft holes. The flexible drive unit is connected to the rotating part 19. By reasonably setting the relative position of the guide groove 20 and the rotating part 19, the flexible drive unit can be driven to move within the guide groove 20 by rotating the rotating part 19.

[0035] The cross-sectional shape of the opposite ends of the shaft holes of the two drive units 21 can be quadrilateral. The cross-sectional shape of the limiting section 27 of the shaft body 22 can also be quadrilateral, allowing them to fit together. The shaft body 22 enables the two adjacent drive units 21 to be rotatably connected. When the limiting section 27 of the shaft body 22 is in the shaft hole of one drive unit 21, the two drive units 21 can rotate relative to each other. When the limiting section 27 of the shaft body 22 is in both shaft holes, the two drive units 21 cannot rotate relative to each other. When the flexible drive unit moves, causing the drive unit 21 to enter the straight section, the limiting section 27 of the shaft body 22 is located in the polygonal ends of the two shaft holes, meaning that the two drive units 21 cannot rotate relative to each other. At this time, the control unit 17 can be moved by the flexible drive unit. The connection structure between the flexible drive unit and the control unit 17 can be selected from existing structures. For example, the control unit 17 can be provided with a through groove extending radially along its rotation circumference, and the drive unit 21 closest to the control unit 17 passes through the through groove.

[0036] The advantages of this embodiment are as follows: First, the flexible drive unit can deform before entering the straight segment, facilitating a reasonable arrangement of its position. This allows the flexible drive unit to be set as long as possible, enabling it to drive the control unit 17 to rotate over a wider range of angles. This ensures that the control unit 17 can contact the force-bearing part 15 or the moving part 18 respectively, while also allowing the control unit 17 to be fully housed within the moving part 16, reducing the space occupied by the moving part 16 and the control unit 17. Consequently, the moving part 16 can move above or below the rotation axis of the valve body 10. Second, by increasing the rotation angle range of the control unit 17 through the flexible drive unit, the lever effect generated by the control unit 17 can be increased, allowing the control unit 17 to drive the valve body 10 to rotate with less effort. Furthermore, the rotation of the rotating part 19 to drive the flexible drive unit to move facilitates the simultaneous movement of multiple flexible drive units and saves operating space.

[0037] like Figure 5 and Figure 6 As shown, in some other embodiments, between two adjacent drive units 21, the cross-sectional shape of the entire shaft hole of one of the drive units 21 is polygonal. Before the limiting section 27 of the shaft body 22 is inserted into the drive unit 21, the cylindrical section of the shaft body 22 is in clearance fit with the shaft hole of the drive unit 21. This can reduce the wear of the shaft body 22 and make the relative rotation of the two drive units 21 more flexible. When the limiting section 27 of the shaft body 22 is in the shaft holes of both drive units 21 at the same time, the clearance between them can be eliminated.

[0038] like Figure 2 As shown, in some embodiments, the cover 9 is provided with a connecting portion 12, which is detachably connected to the bottom wall 11. The connecting portion 12 has a hollow structure, and an extension portion 13 is provided inside the connecting portion 12. The extension portion 13 is detachably connected to the rotating portion 19. The connecting portion 12 can be threaded to the bottom wall 11, so that the cover 9 can be fixed to the bottom wall 11 through the connecting portion 12. The specific structure of the detachable connection between the extension portion 13 and the rotating portion 19 can be selected from existing structures. When the extension portion 13 is connected to the rotating portion 19, the rotating portion 19 can be rotated through the extension portion 13, and the moving portion 16 can be moved through the extension portion 13, which facilitates the control of the valve body 10. The extension portion 13 is disposed inside the connecting portion 12, so that the outer peripheral wall of the connecting portion 12, the valve body 10, the bottom wall 11, and the cover 9 can form a closed chamber. It should be noted that in the aforementioned embodiment where the receiving component 7 is fixed by suspension, the hanging ring can be provided on the extension 13. When suspending, the rotation of the receiving component 7 should be restricted to prevent the extension 13 from rotating, thereby causing the rotating part 19 to rotate.

[0039] like Figure 5As shown, in some embodiments, the receiving component 7 further includes a drive ring 23 and a plurality of abutment portions 24. The drive ring 23 is rotatably connected to the moving part 16, and the rotation axis of the drive ring 23 extends along the lifting direction of the lifting platform 5. The abutment portions 24 are movably connected to the drive ring 23 along the axial direction of the drive ring 23. The plurality of abutment portions 24 are spaced apart from the plurality of control parts 17 on the drive ring 23. The moving part 16 is provided with a guide slope 26, and the abutment portions 24 abut against the guide slope 26. Between two adjacent control parts 17, when the drive ring 23 is configured to rotate forward, the abutment portion 24 is disposed at the bottom of one of the guide grooves 20; when the drive ring 23 is configured to rotate in the reverse direction, the abutment portion 24 is disposed at the top of the other guide groove 20. The forward rotation direction of the drive ring 23 can be clockwise or counterclockwise; correspondingly, the reverse rotation direction of the drive ring 23 can be counterclockwise or clockwise.

[0040] When the drive ring 23 rotates, it can move the abutment part 24, which abuts against the guide slope 26. As the drive ring 23 moves, the abutment part 24 can move along the axial direction of the drive ring 23, allowing its position to be adjusted. For example, between two adjacent guide grooves 20, when the drive ring 23 rotates clockwise, the abutment part 24 moves to the bottom of one guide groove 20; when the drive ring 23 rotates counterclockwise, the abutment part 24 can move to the top of the other guide groove 20.

[0041] like Figure 5 and Figure 6 As shown, the axial direction of the shaft 22 can extend along the lifting direction of the lifting platform 5. The abutment part 24 is used for the shaft 22 to abut against, so as to drive the shaft 22 to move. When the abutment part 24 is located at the bottom of the guide groove 20, the limiting section 27 of the shaft 22 is in the shaft hole of the two drive units 21, and the two drive units 21 cannot rotate relative to each other. When the abutment part 24 is located at the top of the guide groove 20, the limiting section 27 of the shaft 22 is in one drive unit 21, and at this time the two drive units 21 can rotate relative to each other.

[0042] like Figure 5 As shown, the abutment part 24 may be provided with a limit ring 25 to limit the distance that the abutment part 24 moves away from the moving part 16. The guide groove 20 may be provided with a notch so that the shaft 22 can extend out of the guide groove 20, and the shaft 22 and the notch cooperate to improve the movement accuracy of the drive unit 21 when it moves along the guide groove 20.

[0043] The advantages of this embodiment are that by driving the abutment part 24 to move via the drive ring 23, and then driving the shaft 22 to move via the abutment part 24, multiple abutment parts 24 can be driven to move simultaneously. Furthermore, the force on the multiple abutment parts 24 can be evenly distributed, reducing the risk of excessive wear on the abutment parts 24. Additionally, an abutment part 24 can be alternately positioned at the top or bottom of the guide groove 20, preventing excessive wear caused by a single point of force on the abutment part 24. Simultaneously, stress concentration between the abutment part 24 and the drive ring 23 can be eliminated.

[0044] This invention also discloses a method for detecting the structure of pit mud using the aforementioned pit mud structure detection device. An X-ray scanning device is used as the detection component, with the emitting end 3 for emitting X-rays and the receiving end 4 for receiving X-rays. When detecting the pit mud structure, a pit mud sample is selected and placed on the receiving component 7, ensuring the sample is within the detection area of ​​the X-ray scanning device. The sample is then scanned using the X-ray scanning device to obtain a 3D image of its internal structure, acquiring the pore structure parameters. The obtained 3D image and pore structure parameters are then used to analyze the pit mud sample.

[0045] The pore structure parameters of the pit mud samples include soil porosity, pore compaction, connectivity, fractal dimension, and anisotropy. Soil porosity provides habitat for microorganisms in the pit mud and affects gas exchange and water transport, thus determining the overall fermentation performance. Pore compaction regulates the efficiency and sustainability of fermentation by influencing the structural stability and microbial protection capabilities of the pit mud. Fractal dimension is an indicator that quantifies the complexity of the pit mud pore structure; its value is closely related to microbial diversity and the degree of pit mud aging. Anisotropy describes the differences in the pit mud pore structure in different directions; these differences affect the uniformity of the distribution of substances and microorganisms, ultimately impacting the fermentation effect of the pit.

[0046] By analyzing soil porosity, pore density, connectivity, fractal dimension, and anisotropy, traditional, experience-based fermentation pit management is transformed into precise control based on pore structure science. This provides guidance for optimizing the microbial environment within the pit, significantly improving fermentation efficiency and the stability of the final wine quality, and extending the lifespan of the fermentation pit. Taking soil porosity as an example, those skilled in the art can set a standard range; if the soil porosity falls within this range, the pore structure parameters of the pit mud sample meet the requirements in that aspect. Similarly, other parameters can be analyzed in the same way.

[0047] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
