[0045] The purpose of the present invention is to provide a device and method for detecting the surface water content of earthen heritage cultural relics, so as to solve the problems existing in the above related technologies, and minimize the external environmental interference and improve the accuracy of the detection results when detecting the surface water content of earthen heritage cultural relics.

[0046] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Embodiment 1

[0048] This embodiment provides a device for detecting the surface water content of earthen heritage cultural relics. Please refer to Figures 1-9 , which includes a support unit, a shielding unit 1, and a detection unit 2. Among them, the shielding unit 1 includes a shielding plate 6, and the shielding plate 6 is slidably connected to the support unit; the detection unit 2 includes a supporting component 17 and a detection component 16. The supporting component 17 includes a supporting bracket that can support the earthen heritage cultural relic, and the supporting bracket is slidably connected to the support unit; the detection component 16 includes a supporting element and a detector 20. The supporting element is located at the top of the supporting bracket and the relative position between the two can be adjusted. The supporting element and the supporting bracket enclose a cylindrical structure with an open top. The shielding plate 6 is located above the supporting element and can abut against the top of the supporting element to shield the opening of the cylindrical structure enclosed by the supporting element and the supporting bracket. The shielding plate 6, the supporting element, and the supporting bracket enclose a detection cavity; the detector 20 is slidably arranged on the supporting element to detect the earthen heritage cultural relic in the detection cavity.

[0049] The surface moisture content detection device for earthen heritage cultural relics of the present invention has a support bracket that can support the earthen heritage cultural relics to be detected. The support bracket can adjust its position relative to the support unit, facilitating the placement of the earthen heritage cultural relics. The support element is located at the top of the support bracket, and the two can form a cylindrical structure with an open top. The earthen heritage cultural relics are located inside the cylindrical structure. The relative position between the support element and the support bracket can be adjusted to meet the detection requirements of earthen heritage cultural relics of different specifications, and at the same time, the detector 20 on the support element can meet the detection distance requirements. After the earthen heritage cultural relics are placed, the baffle 6 blocks the opening of the cylindrical structure formed by the support element and the support bracket. The baffle 6, the support element, and the support bracket enclose a closed detection cavity, and the earthen heritage cultural relics are located inside the detection cavity for moisture content detection, minimizing the interference of the external environment on the detection and effectively improving the accuracy of the detection results. The support unit provides stable support for the shielding unit 1 and the detection unit 2. At the same time, the surface moisture content detection device for earthen heritage cultural relics of the present invention improves the convenience of detection operation and is conducive to improving the detection work efficiency.

[0050] Among them, the support bracket includes a support cross-block 28 and a placement rack 27 arranged on the support cross-block 28. The placement rack 27 can support the earthen heritage cultural relics. The support cross-block 28 can drive the placement rack 27 to slide up and down in the vertical direction to adjust the position of the placement rack 27, facilitating the placement of the earthen heritage cultural relics to be detected and adjusting the position to meet the detection requirements after the earthen heritage cultural relics are placed. In this specific embodiment, the placement rack 27 has an open-top structure, and the cross-sectional shape of the placement rack 27 in the horizontal direction is the same as that of the support element. The support element is a hollow structure and is slidably sleeved outside the placement rack 27, so that the support bracket and the support element can form a cylindrical structure with an open top, providing a guarantee for constructing a closed detection cavity. The sliding direction of the support element is parallel to the vertical direction. When the support element slides to abut against the support cross-block 28, it means that it has slid to the limit position. The relative sliding of the support element and the support bracket can adapt to the detection of different earthen heritage cultural relics, and at the same time ensure that the detector 20 arranged on the support element meets the detection distance requirements and ensures the normal operation of the detector 20. In practical applications, the support cross-block 28 and the placement rack 27 can be detachably connected, which is convenient for removing the placement rack 27 for cleaning and maintenance during application, providing convenience for subsequent detection work.

[0051] It should also be noted here that in this specific embodiment, the baffle 6 is a cylindrical structure with an open bottom. While blocking and closing the opening of the cylindrical structure formed by the support bracket and the support element, it provides a certain installation and activity space for the detection unit 2, ensuring that the detector 20 can smoothly carry out detection work and improving the adaptability of the detection device.

[0052] To drive the reciprocating movement of the supporting bracket, the supporting component 17 further includes a driving hydraulic telescopic seat 29. The fixed end of the driving hydraulic telescopic seat 29 is connected to the supporting unit, and the movable end of the driving hydraulic telescopic seat 29 is connected to the bottom of the supporting cross block 28 to drive the reciprocating movement of the supporting bracket. The driving hydraulic telescopic seat 29 can adopt structures such as a hydraulic cylinder or an electric telescopic rod to drive the position adjustment of the supporting cross block 28 and the placement rack 27, which is convenient for placing the earthen site cultural relics and meets various detection requirements, improving the automation degree of the detection device. It should be explained here that when the driving hydraulic telescopic seat 29 is driven by hydraulic pressure, air pressure or electricity, the driving hydraulic telescopic seat 29 is connected to an external pressure source and a power source. External pressure workstations, external or built-in power supplies, etc. can be selected to ensure the smooth operation of the driving hydraulic telescopic seat 29. Selecting a suitable power source is a common means for those skilled in the art and will not be elaborated here.

[0053] Meanwhile, the supporting component 17 further includes a telescopic auxiliary mechanism 3. The telescopic auxiliary mechanism 3 includes a first telescopic docking hinge seat 33, a telescopic hydraulic follower rod 32, and a second telescopic docking hinge seat 31. The first telescopic docking hinge seat 33 is connected to the support unit. The fixed end of the telescopic hydraulic follower rod 32 is hinged to the first telescopic docking hinge seat 33, and the movable end of the telescopic hydraulic follower rod 32 is hinged to the second telescopic docking hinge seat 31. The second telescopic docking hinge seat 31 is connected to the support cross block 28. When the active hydraulic telescopic seat 29 drives the support cross block 28 to move in the vertical direction, the telescopic hydraulic follower rod 32 correspondingly makes a telescopic movement, and the telescopic hydraulic follower rod 32 rotates relative to the first telescopic docking hinge seat 33 and the second telescopic docking hinge seat 31 to achieve the purpose of assisting in driving the support cross block 28 to move in the vertical direction, while avoiding affecting the movement direction of the support cross block 28. When the active hydraulic telescopic seat 29 drives the support cross block 28 and the placement rack 27 to adjust their positions, the telescopic auxiliary mechanism 3 correspondingly acts to assist in supporting the support cross block 28 and the placement rack 27, ensuring that the support cross block 28 and the placement rack 27 can move smoothly in the vertical direction, providing an additional support for the smooth movement of the support cross block 28 and the placement rack 27, avoiding the support cross block 28 and the placement rack 27 from jamming and being unable to move, and improving the movement stability and reliability of the support cross block 28 and the placement rack 27. Among them, the telescopic hydraulic follower rod 32 can be selected from structures such as hydraulic cylinders or electric telescopic rods to meet different working conditions. In order to improve the uniform force distribution of the support cross block 28 and the placement rack 27, the number of the telescopic auxiliary mechanisms 3 is multiple groups. The telescopic auxiliary mechanisms 3 are arranged around the active hydraulic telescopic seat 29. In this specific embodiment, the number of the telescopic auxiliary mechanisms 3 is four groups, and the connection lines of the four groups of telescopic auxiliary mechanisms 3 form a rectangle. The active hydraulic telescopic seat 29 is arranged at the center of the rectangle formed by the four groups of telescopic auxiliary mechanisms 3 to improve the uniform force distribution of the support cross block 28 and the placement rack 27, thereby further improving the movement stability of the support cross block 28 and the placement rack 27; in other specific embodiments that can be realized by the present invention, the number and distribution of the telescopic auxiliary mechanisms 3 can also be adjusted according to the specific shapes and specifications of the support cross block 28 and the placement rack 27 to meet different specific working conditions, such as multiple groups of telescopic auxiliary mechanisms 3 being arranged in a circular array, etc.

[0054] Specifically, the detection component 16 further includes a support fixing base plate 23, a lifting adjustment rod 24, and a docking fixing connecting block 25. The support fixing base plate 23 is connected to the support cross block 28. The length of the lifting adjustment rod 24 can be adjusted. The fixed end of the lifting adjustment rod 24 is connected to the support fixing base plate 23, and the movable end of the lifting adjustment rod 24 is connected to the docking fixing connecting block 25. The docking fixing connecting block 25 is connected to the support component. By adjusting the distance between the support component, the support cross block 28, and the placement rack 27, the working distance of the detector 20 disposed on the support component can be adjusted to ensure that the detector 20 can detect the water content of the earthen site cultural relics. The lifting adjustment rod 24 of the present invention is parallel to the vertical direction. The lifting adjustment rod 24 makes a telescopic movement, which can drive the docking fixing connecting block 25 to move in the vertical direction, and further drive the support component connected to the docking fixing connecting block 25 to be adjusted in the vertical direction. In practical applications, in order to improve the uniform stress of the support component, multiple groups of lifting adjustment rods 24 can be provided to ensure the stable movement of the support component. In addition, the lifting adjustment rod 24 can be selected with a hydraulic drive or an electric drive structure according to different working conditions. In the detection unit 2 of the present invention, the heights of the support bracket and the support component can both be adjusted, greatly improving the adaptability of the detection unit 2 to earthen site cultural relics of different specifications, while ensuring the normal operation of the detector 20, and improving the flexibility and reliability of the detection device.

[0055] In this specific embodiment, the support component includes a support plate 19, a track plate 22, and a displacement slider 21. The support plate 19 is a ring-shaped frame structure. The support plate 19 can cover the outside of the placement rack 27 and form a closed detection cavity with the placement rack 27 and the shielding plate 6. In this specific embodiment, the support plate 19 is a rectangular frame structure. The cross-sectional shapes of the placement rack 27 and the shielding plate 6 are both rectangles matching the support plate 19, and the detection cavity formed by the three is a cuboid cavity. In practical applications, the shape of the support plate 19 can also be adjusted according to actual detection requirements, such as being set as a circular ring-shaped frame structure or a hollow prismatic structure layer, etc. The cross-sectional shape of the placement rack 27 matches the shape of the support plate 19, and the shielding plate 6 can be selected with a matching shape or other shapes with a larger area that can cover the opening of the support plate 19 (the opening of the support plate 19, that is, the top opening of the cylindrical structure formed by the support plate 19 and the placement rack 27). The track plate 22 is connected to the support plate 19. The displacement slider 21 is slidably disposed on the track plate 22. The sliding direction of the displacement slider 21 is parallel to the horizontal direction. The detector 20 is disposed on the displacement slider 21. The track plate 22 and the displacement slider 21 provide a stable installation foundation for the detector 20 and enable the detector 20 to adjust its position in the horizontal direction to meet the requirements for detecting the water content on the surface of earthen site cultural relics.

[0056] More specifically, the detection unit 2 further includes a detection driver and a detection lead screw 18. The output end of the detection driver is connected to the detection lead screw 18. The detection lead screw 18 is rotatably connected to the support plate 19. The detection lead screw 18 is threadedly connected to the displacement slider 21. The detection lead screw 18 is arranged parallel to the track plate 22. The detection driver drives the detection lead screw 18 to rotate, and then drives the displacement slider that is threadedly connected to it to slide reciprocally, driving the detector 20 to adjust the detection position. The track plate 22 provides guidance for the reciprocal sliding of the displacement slider 21, ensuring the accuracy of the reciprocal movement of the displacement slider 21, and further improving the displacement adjustment accuracy of the detector 20. Among them, the detection driver can be selected as a motor, using a lead screw structure to transmit power, with high transmission accuracy, effectively ensuring the movement reliability of the displacement slider 21; in other specific implementation manners that can be realized in the present invention, the detection driver can also use other transmission structures to drive the displacement slider 21 to move, such as a gear transmission mechanism, a belt transmission mechanism, etc., to meet different working conditions.

[0057] Furthermore, the shielding unit 1 further includes a shielding driver 10, a shielding lead screw 12, a first docking link 13, and an adapter seat 14. The shielding driver 10 is arranged on the support unit. The output end of the shielding driver 10 is connected to one end of the shielding lead screw 12. The other end of the shielding lead screw 12 is rotatably connected to the adapter seat 14. The rotation axis of the shielding lead screw 12 is parallel to the vertical direction. The adapter seat 14 is connected to the support unit. The first docking link 13 is threadedly connected to the shielding lead screw 12. The first docking link 13 is connected to the shielding plate 6. The shielding driver 10 can be selected in the form of a combination of a motor and a reducer 11. The shielding driver 10 drives the shielding lead screw 12 to rotate, and then drives the first docking link 13 that is threadedly engaged with the shielding lead screw 12 to move reciprocally in the vertical direction, so as to achieve the purpose of driving the shielding plate 6 to move by using the first docking link 13, enabling the shielding plate 6 to move to the top of the support plate 19, and finally enclosing a closed detection cavity. The adapter seat 14 provides stable support for the shielding lead screw 12, ensuring the smooth rotation of the shielding lead screw 12. In practical applications, a bearing can be provided between the adapter seat 14 and the end of the shielding lead screw 12 to ensure the rotation reliability of the shielding lead screw 12. In addition, the specific structure of the transmission mechanism can be adjusted according to the actual working conditions, such as selecting a sprocket transmission mechanism, a belt transmission mechanism, etc., to ensure that the shielding driver 10 can drive the shielding plate 6 to move.

[0058] In order to further improve the movement reliability of the baffle 6, the shielding unit 1 further includes a cooperating guide rod 35 and a second docking link 34. The cooperating guide rod 35 is connected to the support unit. The second docking link 34 is slidably connected to the cooperating guide rod 35. The reciprocating sliding direction of the second docking link 34 is parallel to the rotation axis of the shielding lead screw 12. The second docking link 34 is connected to the baffle 6. The second docking link 34 and the first docking link 13 are symmetrically arranged on both sides of the baffle 6 with the midline of the baffle 6 as the axis. While the shielding lead screw 12 cooperates with the first docking link 13 to drive the baffle 6 to move, the second docking link 34 reciprocally slides along the cooperating guide rod 35 to provide support for the baffle 6. The second docking link 34 and the first docking link 13 are symmetrically arranged, ensuring the uniform stress of the baffle 6 and improving the smoothness of the reciprocating movement of the baffle 6. In this specific embodiment, the cooperating guide rod 35 is a cylindrical rod. The second docking link 34 has a through hole adapted to the cooperating guide rod 35. The second docking link 34 is slidably sleeved outside the cooperating guide rod 35, playing a guiding role for the reciprocating movement of the baffle 6. In practical applications, the cooperating guide rod 35 can also be set as a prismatic structure. While the cooperating guide rod 35 and the second docking link 34 cooperate for guiding, the rotation of the second docking link 34 is avoided, further improving the movement reliability of the baffle 6.

[0059] Correspondingly, the shielding unit 1 further includes a shielding auxiliary mechanism 4. The shielding auxiliary mechanism 4 includes a first shielding docking hinge seat 9, a shielding hydraulic follower rod 8, and a second shielding docking hinge seat 7. The first shielding docking hinge seat 9 is connected to the support unit. The fixed end of the shielding hydraulic follower rod 8 is hinged to the first shielding docking hinge seat 9. The movable end of the shielding hydraulic follower rod 8 is hinged to the second shielding docking hinge seat 7. The second shielding docking hinge seat 7 is connected to the baffle 6. The number of the shielding auxiliary mechanisms 4 is two groups. The two groups of shielding auxiliary mechanisms 4 are symmetrically arranged on both sides of the baffle 6 with the midline of the baffle 6 as the axis. When the shielding driver 10 drives the baffle 6 to reciprocate in the vertical direction, the shielding hydraulic follower rod 8 makes a telescopic movement and rotates relative to the first shielding docking hinge seat 9 and the second shielding docking hinge seat 7 to achieve the purpose of assisting the movement of the baffle 6, further improving the movement stability and reliability of the baffle 6, and at the same time improving the uniform stress of the baffle 6. Similarly, the shielding hydraulic follower rod 8 can select structures such as a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod.

[0060] It should also be noted that the support unit includes an installation plate 30, a first limit back plate 15 and a second limit back plate 26 provided on the installation plate 30. The active hydraulic telescopic seat 29 is provided on the installation plate 30. The first limit back plate 15 is perpendicular to the installation plate 30 and the two form an L-shaped structure. The second limit back plate 26 is connected to the first limit back plate 15. The shielding plate 6 is slidably connected to the first limit back plate 15. The shielding driver 10 is fixed on the first limit back plate 15 to drive the shielding plate 6 to reciprocate. The bearing bracket is slidably provided above the installation plate 30. The first shielding docking hinge seat 9 is fixed behind the first limit back plate 15. The first limit back plate 15 and the second limit back plate 26 cooperate to limit the support cross block 28, the placement rack 27, the support plate 19 and the shielding plate 6, so that the device can successfully construct a detection cavity, reduce the interference and influence of the external environment on the detection, and improve the accuracy of the detection result.

[0061] Furthermore, the shielding unit 1 further includes a position detector 5, and the position detector 5 can detect whether the detector 20 is within the detection distance range. The position detector 5 can detect the position of the displacement slider 21 to achieve the purpose of detecting the position of the detector 20, ensure the smooth progress of the detection process, and improve the working reliability of the detection device. In practical applications, the position detector 5 can be a position sensor, a distance sensor or other types of sensors. In addition, multiple position detectors 5 can be provided. When the displacement slider 21 slides to the limit position, the position detector 5 can issue an alarm to prompt the detection personnel. It should be explained here that the specific structure and working principle of the position detector 5 are common means for those skilled in the art and will not be elaborated here.

[0062] In this specific embodiment, the detector 20 is a hyperspectral imager, and the hyperspectral imager can scan the earthen site cultural relics to detect the water content on the surface of the earthen site cultural relics.

[0063] When the soil heritage cultural relic surface water content detection device of the present invention is in use, the user controls the active hydraulic telescopic seat 29 to move downward, so that the active hydraulic telescopic seat 29 drives the placement rack 27 and the support cross block 28 to reach the bottommost position. The soil heritage cultural relics to be detected are placed on the placement rack 27. At this time, the four corners of the support cross block 28 are supported by the telescopic hydraulic driven rods 32, the second telescopic docking hinge seats 31, and the first telescopic docking hinge seats 33 to ensure the connection stability of the placement rack 27 and the support cross block 28. Then, the user controls the active hydraulic telescopic seat 29 to extend, so that the active hydraulic telescopic seat 29 drives the placement rack 27 and the support cross block 28 to reach a suitable position. At this time, the telescopic hydraulic driven rods 32 extend accordingly. At the same time, the telescopic hydraulic driven rods 32 can be adjusted in angle through the second telescopic docking hinge seats 31 and the first telescopic docking hinge seats 33 to cooperate in the movement support work of the support cross block 28. The side end of the support cross block 28 is fixed to the support fixed bottom plate 23. Then, the user controls the lifting adjustment rod 24 to operate, so that the lifting adjustment rod 24 drives the docking fixed connecting block 25 and the support plate 19 to move downward, so that the support plate 19 is aligned and limited with the support cross block 28. Then, the shielding driver 10 is started, and the shielding screw rod 12 is controlled to rotate through the reducer 11. The shielding screw rod 12 can drive the first docking connecting rod 13 to move, so that the first docking connecting rod 13 drives the shielding plate 6 to move. At this time, the shielding plate 6 can reach the upper end of the support plate 19. At the same time, the in-place detector 5 performs position induction and alarm work. When the shielding plate 6 moves, the shielding hydraulic driven rod 8 can follow the telescopic adjustment at this time. At the same time, the shielding hydraulic driven rod 8 can also cooperate in angle regulation through the hinged connection of the second shielding docking hinge seat 7 and the first shielding docking hinge seat 9 to prevent jamming. Then, the detection driver drives the detection screw rod 18 to rotate, so that the displacement slider 21 moves on the track plate 22, changing the position of the detector 20, so that the detector 20 scans the soil heritage cultural relics on the placement rack 27 to perform the water content detection work and complete the work.

[0064] The soil heritage cultural relic surface water content detection device of the present invention effectively reduces the interference and influence of the external environment on the detection result by constructing a closed detection cavity, improving the detection accuracy. Moreover, the detection device of the present invention has a compact structure and convenient operation, improving the work efficiency of the soil heritage cultural relic surface water content detection.

[0074] In the method for detecting the surface moisture content of earthen heritage cultural relics of the present invention, the earthen heritage cultural relic is arranged in a closed detection cavity for detection, which minimizes the interference and influence of the external environment on the detection and improves the accuracy of the detection result.

[0075] In practical applications, when using the method for detecting the surface moisture content of earthen heritage cultural relics of the present invention to detect the surface moisture content of earthen heritage cultural relics, it includes the following operating steps:
