[0002] Coal mine geological surveying is a crucial step in the coal mining process. It provides indispensable basic data for coal mine planning, design, production construction, and safe operation. Through precise measurement of coal mine geological conditions, parameters such as coal seam thickness, dip angle, and strike, as well as the distribution of geological structures such as faults and folds, can be accurately determined. This allows for the rational planning of roadway layout, determination of coal mining methods, and improvement of coal resource extraction efficiency.
[0003] However, all these instruments have a calibration problem, especially the deviation of angular displacement, which has a relatively large error each time it is used. Currently, the reset is done by manual correction or by calculating the difference, both of which are time-consuming and labor-intensive.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides an easily adjustable coal mine geological surveying device, such as... Figures 1 to 4 As shown, the device includes a foot-type frame 1. The upper surface of the foot-type frame 1 is provided with a mounting base 2 movably connected via a pivot. The lower surface of the mounting base 2 is provided with a hinge shaft. The mounting base 2 is movably connected to the foot-type frame 1 via the hinge shaft on its lower surface. A through hole is opened in the middle of the upper surface of the mounting base 2. A shaft connecting seat 3 is movably connected to the mounting base 2 through the through hole at the top. Upright plates 301 are provided on both sides of the upper surface of the shaft connecting seat 3. A nut 4 is passed through one side of the upright plate 301. One end of the nut 4 passes through the interior of the shaft connecting seat 3. A support frame 5 is fixedly installed on the upper surface of the shaft connecting seat 3 via one end of the nut 4. Both sides of the support frame 5 are provided with connection holes. The support frame 5 is fixedly connected to the nut 4 through the connection holes on both sides. A groove 501 is provided on one edge of the upper surface of the support frame 5. A collar 6 is movably connected inside the groove 501. An angle plate 7 is movably connected to the outer arc surface of the collar 6. A shaft hole 701 is provided on one side of the upper surface of the angle plate 7. An arc-shaped slide 702 is provided on the side of the angle plate 7 near the shaft hole 701. A rotating shaft 8 is connected through the inner arc surface of the shaft hole 701. One end of the rotating shaft 8 extends to the lower surface of the mounting base 2. A synchronous wheel 9 is fixedly installed on the outer arc surface of the rotating shaft 8.
[0026] When the angular displacement measuring device is placed on the rotating shaft 8 and begins to rotate, the connected angular displacement plate 7 will also rotate synchronously. The angular displacement plate 7 is equipped with an arc-shaped slide rail 702. The pin 10, which is locked within the arc-shaped slide rail 702, slides within the arc-shaped slide rail 702 as the angular displacement plate 7 rotates. Since the front end of the pin 10 is connected to the connecting rod 11, the connecting rod 11 will change its angle around the pin 10 as it slides within the arc-shaped slide rail 702. This change in the angle of the connecting rod 11 will then cause the connected threaded rod 13 to move, thus enabling the angular displacement function to perform all-round detection of the boundaries and morphology of geological structures. When detecting faults, by adjusting... The angular displacement and faulting of the rock strata on both sides of the fault are measured from different directions. During this process, the electronic vernier caliper 18 records relevant data in real time. When the angular displacement measuring device placed on the rotating shaft 8 completes its rotation and a reset operation is required, the change in the reading of the electronic vernier caliper 18 becomes the key basis for judging whether the reset is successful as the rotating shaft 8 gradually returns to its initial position. If the electronic reading of the electronic vernier caliper 18 eventually returns to zero, it indicates that the entire reset process is accurate and error-free, and the device has successfully returned to its initial state. This ensures that subsequent measurement work can be carried out under standard starting conditions, effectively guaranteeing the accuracy of the measurement data and the measurement process.
[0027] A pin 10 is movably engaged in the arc-shaped slide 702 on the upper surface of the corner plate 7. A connecting rod 11 is sleeved on the outer arc surface of the pin 10. A groove 111 is opened on one side of the outer arc surface of the connecting rod 11. A hole 112 is provided at the top of the outer arc surface of the connecting rod 11. The inner arc surface of the hole 112 is movably engaged with the pin 10. A thread is provided on one end face of the connecting rod 11. A kit 12 is movably connected to the connecting rod 11 through the thread on one side. A frame groove 121 is opened on the upper surface of the kit 12. A threaded rod 13 is threaded in the frame groove 121. A connecting ring 14 is threaded at one end of the threaded rod 13. A sampling sleeve 15 is provided on the lower surface of the connecting ring 14. A strip hole 16 is opened on the outer arc surface of the sampling sleeve 15. A shovel head 19 is provided at the bottom end of the sampling sleeve 15. A bulldozer 17 is slidably sleeved on the outer arc surface of the sampling sleeve 15. An electronic vernier caliper 18 is fixedly installed at the top of the rotating shaft 8.
[0028] When the threaded rod 13 moves downward, it pushes the shovel head 19 at one end of the sampling sleeve 15 into the soil. The sampling sleeve 15 and the threaded rod 13 are connected by threads. This design makes the sampling sleeve 15 easy to disassemble after sampling, facilitating subsequent sample processing and analysis. Multiple slotted holes 16 are provided along the length of the surface of the sampling sleeve 15. These slotted holes 16 play an important role in the sampling process. When the shovel head 19 is inserted into the soil and the soil enters the sampling sleeve 15, the slotted holes 16 can... The sampling sleeve 15 can expel air in time, effectively reducing air resistance and ensuring a smooth sampling process. At the same time, the sampling sleeve 15 is connected to a bulldozer 17, which is slidably connected to the sampling sleeve 15 through a strip hole 16. After sampling is completed, the soil inside the sampling sleeve 15 can be smoothly pushed out by pushing the bulldozer 17, which is convenient for collecting samples. In addition, the shovel head 19 at the bottom of the sampling sleeve 15 can easily cut into the soil, greatly improving the efficiency and success rate of soil sampling.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
