[0036] Specifically, the present embodiment is that the device is fixedly installed on the fixed column at the top of the archaeological site by means of the fixed pile foot 107. When the position of the camera 700 needs to be adjusted along the X-axis direction, the two X-axis travel motors 108 are started, and the output shafts of the two X-axis travel motors 108 act on the shockproof transmission component 300, and the X-axis travel gear 104 is driven to rotate through the shockproof transmission component 300, so that the X-axis travel gear 104 rolls along the top of the X-axis travel rack 103, and further drives the X-axis moving seat 102 to move. The X-axis moving seat 102 is connected to the X-axis linear slide block 106 through the sliding connection of the X-axis linear guide 105, and can move more stably. The Y-axis moving seat 202 moves through the shockproof transmission component 300 to drive the camera 700 to move along the X-axis direction, so as to adjust the X-axis position. When the position of the camera 700 needs to be adjusted along the Y-axis direction, the Y-axis travel motor 208 is started, and the output shaft of the Y-axis travel motor 208 acts on the shockproof transmission component 300, and the Y-axis travel gear 204 is driven to rotate through the shockproof transmission component 300, so that the Y-axis travel gear 204 rolls along the top of the Y-axis travel rack 203, and further drives the Y-axis moving seat 202 to move. The Y-axis moving seat 202 is connected to the Y-axis linear guide 205 and the Y-axis linear slider 206 through sliding, and can move more stably. The movement of the Y-axis moving seat 202 drives the camera 700 to move along the Y-axis direction through the shockproof transmission component 300, so as to adjust the Y-axis position. By applying adjustments to the camera 700 in the X-axis direction and the Y-axis direction, image data collection at various angles is performed.

[0037] Embodiment 2: The shockproof transmission component 300 includes a first bearing seat 301 fixedly mounted on the top of the X-axis moving seat 102 and the top of the Y-axis moving seat 202, a driven shaft 302 is rotatably mounted inside the first bearing seat 301, a clutch housing 303 is fixedly mounted on one end of the driven shaft 302, the X-axis travel gear 104 and the Y-axis travel gear 204 are both fixedly mounted on the outer wall of the clutch housing 303, the shockproof transmission component 300 also includes a second bearing seat 305 fixedly mounted on the top of the X-axis moving seat 102 and the top of the Y-axis moving seat 202, a hollow shaft 306 is rotatably mounted inside the second bearing seat 305, a hydraulic coupling housing 307 is fixedly mounted on one end of the hollow shaft 306 close to the driven shaft 302, and the inner wall of the hollow shaft 306 A central shaft 3012 is rotatably installed, and a pump wheel 3018 is fixedly installed at the end of the central shaft 3012. A hydraulic hole 308 is penetrated through the outer wall of the hydraulic coupling housing 307, and an elastic expansion ring 3010 is fixedly installed on the outer wall of the hydraulic coupling housing 307. The elastic expansion ring 3010 is connected with the inside of the hydraulic coupling housing 307 through the hydraulic hole 308. There are multiple hydraulic holes 308, and the multiple hydraulic holes 308 are distributed at equal angles. Oil gaskets 309 are fixedly installed inside the hydraulic holes 308. A driven friction ring 304 is fixedly installed on the inner wall of the clutch housing 303. An active friction ring 3011 is fixedly installed on the outer wall of the elastic expansion ring 3010, and there is a clearance fit between the active friction ring 3011 and the elastic expansion ring 3010.

[0038] The pump wheel 3018 is located inside the hydraulic coupling housing 307, the dustproof side cover 3017 is filled with oil, the first driven gear 3013 is fixedly installed on the end of the central shaft 3012 away from the pump wheel 3018, the second driven gear 3014 is fixedly installed on the outer wall of the end of the hollow shaft 306 away from the hydraulic coupling housing 307, the first driving gear 3015 and the second driving gear 3016 are fixedly installed on the output of the X-axis travel motor 108 and the Y-axis travel motor 208, the first driving gear 3015 is meshed with the first driven gear 3013, the second driving gear 3016 is meshed with the second driven gear 3014, the number of teeth of the first driving gear 3015 is greater than the number of teeth of the second driving gear 3016, and the number of teeth of the first driven gear 3013 is less than the number of teeth of the second driven gear 3014;

[0039] Specifically, in this embodiment, when the output shaft of the X-axis travel motor 108 drives the first driving gear 3015 and the second driving gear 3016 connected thereto to rotate, the second driving gear 3016 rotates to drive the second driven gear 3014 meshing therewith to rotate, and the second driven gear 3014 rotates to further drive the hydraulic coupling housing 307, the elastic expansion ring 3010 and the active friction ring 3011 to rotate together inside the clutch housing 303 through the hollow shaft 306. At the same time, the first driving gear 3015 rotates to drive the central shaft 3012 to rotate through the first driven gear 3013 meshing therewith, and the central shaft 3012 rotates to drive the pump wheel 3018 to rotate inside the hydraulic coupling housing 307. The number of teeth of the gear 3015 is greater than the number of teeth of the second driving gear 3016, so the rotation speed of the first driven gear 3013 is greater than the rotation speed of the second driven gear 3014, that is, the rotation speed of the pump wheel 3018 is greater than the rotation speed of the hydraulic coupling housing 307, and there is a speed difference between the pump wheel 3018 and the hydraulic coupling housing 307. Therefore, the first driven gear 3013 will stir the oil inside the hydraulic coupling housing 307 during the rotation process, and pump the oil through multiple hydraulic holes 308 to the inside of the elastic expansion ring 3010. It should be noted here that the inside of the elastic expansion ring 3010 is also provided with hydraulic pressure. Therefore, after the oil inside the hydraulic coupling housing 307 is pumped to the inside of the elastic expansion ring 3010, the oil inside the elastic expansion ring 3010 The pressure increases continuously, causing it to expand, driving the active friction ring 3011 to move toward the periphery, and gradually releasing from the driven friction ring 304. The friction force generated by the contact between the active friction ring 3011 and the driven friction ring 304 drives the driven friction ring 304 to rotate together with the clutch housing 303. The rotation of the clutch housing 303 drives the X-axis travel gear 104 to rotate, causing the X-axis travel gear 104 to roll along the top of the X-axis travel rack 103, further driving the X-axis moving seat 102 to move. The X-axis moving seat 102 is connected to the X-axis linear guide 105 and the X-axis linear slider 106 through a sliding connection, so that it can move more stably. The movement of the Y-axis moving seat 202 drives the camera 700 to move along the X-axis direction through the anti-vibration transmission component 300, realizing Regarding the adjustment of the X-axis position, it should be noted that, due to the small aperture of the hydraulic hole 308, the oil inside the hydraulic coupling housing 307 enters the elastic expansion ring 3010 at a slow speed through the hydraulic hole 308, which means that the elastic expansion ring 3010 is in a slow expansion process, and the friction between the active friction ring 3011 and the driven friction ring 304 becomes larger and larger as the elastic expansion ring 3010 expands. Therefore, the driving effect of the active friction ring 3011 on the driven friction ring 304 becomes more and more efficient. In other words, the speed of the driven friction ring 304 driven by the elastic expansion ring 3010 is gradually increased, so that when the active friction ring 3011 and the driven friction ring 304 are in contact at the beginning, due to the limited friction between the two,The driven friction ring 304 will not be driven to rotate at full speed together with the clutch housing 303 quickly, nor will the X-axis travel gear 104 be driven to rotate quickly through the clutch housing 303. Therefore, the rolling speed of the X-axis travel gear 104 along the top of the X-axis travel rack 103 is slowly increased, ensuring that the camera 700 will not have a large shake in the initial process of moving along the X-axis. Similarly, the output shaft of the Y-axis travel motor 208 drives the first driving gear 3015 and the second driving gear 3016 connected thereto to rotate, so that when the Y-axis of the camera 700 is adjusted, the camera 700 will not have a large shake in the initial process of moving, so as to obtain the best shooting results.

[0040] Furthermore, a dustproof side cover 3017 is fixedly installed on the outer wall of the hollow shaft 306. The dustproof side cover 3017 is located inside the clutch housing 303, and the outer wall of the dustproof side cover 3017 is rotatably connected to the inner wall of the clutch housing 303. The dustproof side cover 3017 is used to close the open side of the clutch housing 303 to prevent external dust from entering the interior of the clutch housing 303.

[0041] Furthermore, a plurality of ventilation grooves 3003 distributed at equal angles are provided on the side of the clutch housing 303. The ventilation grooves 3003 are located near the edge of the clutch housing 303. The ventilation grooves 3003 are provided in a spiral shape. As the clutch housing 303 rotates, the spirally provided ventilation grooves 3003 play a role in guiding wind, so that air can flow through the interior of the ventilation grooves 3003, taking away the heat generated by the friction between the active friction ring 3011 and the driven friction ring 304, thereby avoiding the driven friction ring 304 and the active friction ring 3011 from burning due to high temperature, and improving the service life of the device.

[0042] Embodiment 3: A fixed pile seat 400 is fixedly installed at one end of the Y-axis moving seat 202 away from the Y-axis walking motor 208, an adjusting rod 500 is inserted inside the fixed pile seat 400, a lifting ear 600 is fixedly installed at the bottom of the adjusting rod 500, a camera 700 is fixedly installed at the bottom of the lifting ear 600, a fastening bolt 800 is screwed on the outer wall of the fixed pile seat 400, and the end of the fastening bolt 800 abuts against the outer wall of the adjusting rod 500;

[0043] Specifically, the present embodiment uses the fixed pile seat 400 to fix and limit the adjusting rod 500 and the lifting ear 600 to ensure the stability of the camera 700, and by loosening the fastening bolt 800, the adjusting rod 500 can be slid up and down along the inner wall of the fixed pile seat 400 to adjust the height of the camera 700, and after the height adjustment of the camera 700 is completed, the adjusting rod 500 can be locked by tightening it, so that the height of the camera 700 will not change.

[0044] In this scheme, a rail-type archaeological image acquisition device based on the principle of photogrammetry is fixedly installed on a fixed column at the top of the archaeological site by means of a fixed foot 107 when working;

[0045] When the position of the camera 700 needs to be adjusted along the X-axis direction, the two X-axis travel motors 108 are started, and the output shafts of the two X-axis travel motors 108 drive the first driving gear 3015 and the second driving gear 3016 connected thereto to rotate, and the second driving gear 3016 rotates to drive the second driven gear 3014 meshed therewith to rotate, and the second driven gear 3014 rotates to further drive the hydraulic coupling housing 307, the elastic expansion ring 3010 and the active friction ring 3011 to rotate together inside the clutch housing 303 through the hollow shaft 306, and at the same time, the first driving gear 3015 rotates to drive the central shaft 3012 to rotate through the first driven gear 3013 meshed therewith, and the central shaft 3012 rotates to drive the pump wheel 3014 to rotate. 018 rotates inside the hydraulic coupling housing 307. Since the number of teeth of the first driving gear 3015 is greater than the number of teeth of the second driving gear 3016, the rotation speed of the first driven gear 3013 is greater than the rotation speed of the second driven gear 3014. In other words, the rotation speed of the pump wheel 3018 is greater than the rotation speed of the hydraulic coupling housing 307. There is a speed difference between the pump wheel 3018 and the hydraulic coupling housing 307. Therefore, the first driven gear 3013 will stir the oil inside the hydraulic coupling housing 307 during the rotation process, and pump the oil through multiple hydraulic holes 308 to the inside of the elastic expansion ring 3010. It should be noted here that the inside of the elastic expansion ring 3010 is also provided with hydraulic pressure, so the oil inside the hydraulic coupling housing 307 is pumped to the elastic expansion ring. After the inside of 3010 is moved, the oil pressure inside the elastic expansion ring 3010 continues to increase, causing it to expand, driving the active friction ring 3011 to move toward the periphery, and gradually releasing from the driven friction ring 304. The friction force generated by the contact between the active friction ring 3011 and the driven friction ring 304 drives the driven friction ring 304 to rotate together with the clutch housing 303. The rotation of the clutch housing 303 drives the X-axis travel gear 104 to rotate, so that the X-axis travel gear 104 rolls along the top of the X-axis travel rack 103, further driving the X-axis moving seat 102 to move. The X-axis moving seat 102 is connected to the X-axis linear guide 105 and the X-axis linear slider 106 through a sliding connection, and can move more stably. The movement of the Y-axis moving seat 202 is driven by the anti-vibration transmission component 300. The camera 700 moves along the X-axis direction to adjust the X-axis position. It should be noted that, due to the small aperture of the hydraulic hole 308, the oil inside the hydraulic coupling housing 307 enters the elastic expansion ring 3010 through the hydraulic hole 308 at a slow speed, which means that the elastic expansion ring 3010 is in a slow expansion process. The friction between the active friction ring 3011 and the driven friction ring 304 increases with the expansion of the elastic expansion ring 3010. Therefore, the driving effect of the active friction ring 3011 on the driven friction ring 304 becomes more and more efficient. In other words, the speed of the driven friction ring 304 driven by the elastic expansion ring 3010 is gradually increased, so that when the active friction ring 3011 and the driven friction ring 304 are in contact at the beginning,Since the friction between the two is limited, the driven friction ring 304 will not be driven to rotate at full speed together with the clutch housing 303, and the X-axis travel gear 104 will not be driven to rotate quickly through the clutch housing 303. Therefore, the rolling speed of the X-axis travel gear 104 along the top of the X-axis travel rack 103 is slowly increased, ensuring that the camera 700 will not have a large shake during the initial movement along the X-axis;

[0046] When the position of the camera 700 needs to be adjusted along the Y-axis direction, the Y-axis travel motor 208 is started, and the output shaft of the Y-axis travel motor 208 drives the first driving gear 3015 and the second driving gear 3016 connected thereto to rotate, and the second driving gear 3016 rotates to drive the second driven gear 3014 meshed therewith to rotate, and the second driven gear 3014 rotates to further drive the hydraulic coupling housing 307, the elastic expansion ring 3010 and the active friction ring 3011 to rotate together inside the clutch housing 303 through the hollow shaft 306, and at the same time, the first driving gear 3015 rotates to drive the central shaft 3012 to rotate through the first driven gear 3013 meshed therewith, and the central shaft 3012 rotates to drive the pump wheel 30 18 rotates inside the hydraulic coupling housing 307. Since the number of teeth of the first driving gear 3015 is greater than the number of teeth of the second driving gear 3016, the rotation speed of the first driven gear 3013 is greater than the rotation speed of the second driven gear 3014. In other words, the rotation speed of the pump wheel 3018 is greater than the rotation speed of the hydraulic coupling housing 307. There is a speed difference between the pump wheel 3018 and the hydraulic coupling housing 307. Therefore, the first driven gear 3013 stirs the oil inside the hydraulic coupling housing 307 during rotation, and pumps the oil to the inside of the elastic expansion ring 3010 through the multiple hydraulic holes 308. It should be noted here that the inside of the elastic expansion ring 3010 is also provided with hydraulic pressure, so the oil inside the hydraulic coupling housing 307 is pumped to the elastic expansion ring 3 010, the internal oil pressure of the elastic expansion ring 3010 continues to increase, causing it to expand, driving the active friction ring 3011 to move toward the periphery, and gradually releasing from the driven friction ring 304. The friction force generated by the contact between the active friction ring 3011 and the driven friction ring 304 drives the driven friction ring 304 to rotate together with the clutch housing 303. The rotation of the clutch housing 303 drives the Y-axis travel gear 204 to rotate, so that the Y-axis travel gear 204 rolls along the top of the Y-axis travel rack 203, further driving the Y-axis moving seat 202 to move. The Y-axis moving seat 202 is connected to the Y-axis linear guide 205 and the Y-axis linear slider 206 through a sliding connection, so that it can move more stably. The movement of the Y-axis moving seat 202 is driven by the anti-vibration transmission component 300. The camera 700 moves along the Y-axis direction to adjust the Y-axis position. It should be noted that, due to the small aperture of the hydraulic hole 308, the oil inside the hydraulic coupling housing 307 enters the elastic expansion ring 3010 through the hydraulic hole 308 at a slow speed, which means that the elastic expansion ring 3010 is in a slow expansion process. The friction between the active friction ring 3011 and the driven friction ring 304 increases with the expansion of the elastic expansion ring 3010. Therefore, the driving effect of the active friction ring 3011 on the driven friction ring 304 becomes more and more efficient. In other words, the rotation speed of the driven friction ring 304 driven by the elastic expansion ring 3010 is gradually increased, so that when the active friction ring 3011 and the driven friction ring 304 are in contact at the beginning,Due to the limited friction between the two, the driven friction ring 304 will not be driven to rotate at full speed together with the clutch housing 303 quickly, and the Y-axis travel gear 204 will not be driven to rotate quickly through the clutch housing 303. Therefore, the rolling speed of the Y-axis travel gear 204 along the top of the Y-axis travel rack 203 is slowly increased, ensuring that there will be no large jitter in the initial process of the camera 700 moving along the Y-axis, so as to obtain the best shooting results. By applying adjustments to the X-axis direction and the Y-axis direction to the camera 700, image data collection at various angles is performed. It should be additionally explained that the camera 700 of the present device is internally integrated with an image processing module and a data storage module. The image processing module The module is used to pre-process and post-process the images taken by the digital camera, including denoising, contrast enhancement, color correction, etc., to improve the quality and readability of the image. At the same time, the image processing module can also stitch and synthesize images, seamlessly stitching multiple images into a complete panoramic image to meet the user's shooting needs for a wide range of scenes. The data storage module is responsible for storing and managing the processed image data. The module can support multiple storage formats, such as JPEG, TIFF, etc., and can select appropriate storage paths and naming rules according to user needs. In addition, the data storage module also has data backup and recovery functions to ensure the security and reliability of the shooting data. ,
