[0002] Coal mine geological survey is one of the key links to ensure the safety and effective mining of coal mines. During the coal mine geological survey process, it is very important to keep the measuring instrument level, because geological instruments are usually very sensitive to slight changes in terrain and geological conditions, and the horizontal state of the instrument directly affects the accuracy of the measurement results. At the same time, it is necessary to prevent the measuring instrument from being damaged by falling rocks.

[0003] Patent publication number "CN219866950U" discloses "a special safety protection frame for coal mine geological survey, including an outer cylinder, the outer side of the outer cylinder is provided with limit grooves at equal intervals, and a movable plate is slidably installed inside the outer cylinder, and the outer edge of the movable plate is fixed with brackets slidably connected to the limit grooves at equal intervals. The fixing bolts are turned to remove the ground plug from the storage slot, and the ground plug and the bracket are maintained in a vertical state. The pad is pushed by the fixing bolts so that the pad is inserted into the stable slot. The stability of the pad when connected to the stable slot is improved by the fixing bolts. Under the setting of the storage slot, the ground plug can be conveniently stored after use to avoid its tip affecting the use, thereby improving the safety performance of the equipment."

[0004] When the current protective frame is installed in a coal mine tunnel, the ground in the coal mine tunnel may be uneven, which may cause the measuring device to tilt, so that errors may occur in the data measured by the measuring device. Utility Model Content
