Detailed Implementation
[0024] Example: A high-precision leveling instrument with automatic leveling for geological surveying, such as... Figure 1-7 As shown, the system includes support legs 1, connecting plates 2, rotating plates 3, handles 4, support frames 5, a level instrument 6, a control panel 601, an inclination sensor 7, a first gear 8, a dual-axis motor 9, a second gear 10, a stepper motor 11, a third gear 12, and a gear ring 13. The tops of the three support legs 1 are rotatably connected to the connecting plates 2, and the tops of the connecting plates 2 are rotatably connected to the rotating plates 3. Handles 4 are welded to the left and right sides of the top of the rotating plates 3, and support frames 5 are welded to the left and right sides of the top of the rotating plates 3. Two support frames 5 are located between corresponding handles 4. A level instrument 6 is rotatably connected to the upper part of the support frames 5, and the control panel is bolted to the center of the top of the level instrument 6. 601. Inclination sensors 7 are bolted to the middle of the left and right sides of the level instrument 6. First gears 8 are keyed to the lower left and right sides of the level instrument 6. A dual-axis motor 9 is bolted to the middle of the top of the rotating disk 3. The two output shafts of the dual-axis motor 9 are keyed to the second gears 10. The first gear 8 and the second gear 10 mesh with each other. A stepper motor 11 is bolted to the right side of the front of the connecting disk 2. The output shaft of the stepper motor 11 is keyed to the third gear 12. A gear ring 13 is welded to the lower periphery of the rotating disk 3. The third gear 12 and the gear ring 13 mesh with each other. The control panel 601 is electrically connected to the two inclination sensors 7, the dual-axis motor 9, and the stepper motor 11.
[0025] When operators need to use this device to assist in geological surveying, firstly, the device is placed on the site to be measured using the support leg 1. Then, the level instrument 6 is started to begin measurement. If the device is accidentally bumped and tilted during the measurement process, the two tilt sensors 7 can detect the tilt angles in the vertical and horizontal directions respectively. When vertical rotation is detected, one of the tilt sensors 7 will detect the vertical tilt angle and direction of the level instrument 6 and send the data to the control panel 601. Subsequently, the control panel 601 will control the dual-axis motor 9, which will drive... The second gear 10 rotates in the opposite direction and angle. At this time, the second gear 10 will mesh with the first gear 8, driving the level 6 to rotate in the opposite direction, thereby completing the vertical correction. When the horizontal direction rotates, another tilt sensor 7 will detect the horizontal tilt angle and direction of the level 6 and send the data to the control panel 601. The control panel 601 will control the stepper motor 11 to drive the third gear 12 to rotate in the corresponding direction and angle. At this time, the third gear 12 will mesh with the gear ring 13, and the gear ring 13 will drive the rotating disk 3 to rotate synchronously, thereby completing the horizontal correction.
[0026] like Figure 1 , Figure 4 and Figure 6 As shown, it also includes a threaded post 14 and a support platform 15. The threaded post 14 is welded to the middle of the bottom of the rotating disk 3. The threaded post 14 passes through the connecting disk 2. The support platform 15 is threadedly connected to the lower part of the threaded post 14. The support platform 15 is located at the bottom of the connecting disk 2.
[0027] When the support leg 1 is not needed, the support platform 15 can be rotated counterclockwise so that the support platform 15 is no longer threaded with the threaded post 14. At this time, the corresponding parts can be pulled upward by pulling the handle 4 upward. At this time, the third gear 12 will disengage from the gear ring 13. After pulling upward until the threaded post 14 is out of the range of the connecting plate 2, the support platform 15 can be rotated clockwise to reset and can be removed from the support leg 1.
[0028] like Figure 4 As shown, it also includes spikes 16. Multiple spikes 16 are glued together in a circular array at the bottom of the support platform 15. The spikes 16 are made of rubber and are used to enhance grip and prevent damage to the ground.
[0029] When the device needs to be placed in a confined space, the disassembled device can be lifted to the target location using the handle 4. When placed on soil, the ground spikes 16 can be inserted downwards into the soil to secure it.
[0030] like Figure 5As shown, it also includes ball bearings 17. Multiple ball bearings 17 are rotatably connected in a circular array on the top periphery of the connecting disk 2. The bottom periphery of the rotating disk 3 has a groove corresponding to the ball bearings 17.
[0031] like Figure 6 and 7 As shown, it also includes an annular piece 18. The annular piece 18 is embedded in the middle of the bottom of the connecting disk 2 and rotatedly connected. The annular piece 18 is located between the connecting disk 2 and the support platform 15, and the support platform 15 abuts against the annular piece 18.
[0032] When the device performs horizontal angle correction, the slide rail will slide into contact with the ball 17 during the rotation of the rotating disk 3, reducing the friction between the rotating disk 3 and the connecting disk 2. At the same time, the annular plate 18 will also rotate together due to the friction of the rotating support platform 15, reducing the friction between the connecting disk 2 and the support platform 15.
