A method of using a coal mine goaf surface subsidence detection device according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1, electrical connection: Move the inclinometer and align the upper end of the inclinometer with the threaded groove (707), then rotate the inclinometer along the threaded groove (707) to make a detachable connection between the inclinometer and the connector (706), and then make an electrical connection between the inclinometer and the cable (704). Step 2, initial clamping: move the inclinometer and place it between the two clamping plates (607). Then, drive the second hydraulic telescopic rod (602) to retract and slide through the second electric hydraulic cylinder (601), thereby driving the connecting plate (603) to move closer to the second electric hydraulic cylinder (601). Then, under the action of the connecting rod (605) rotating along the first connecting shaft (604), the connecting rod (605) rotating along the second connecting shaft (606), and the sliding action of the inner wall of the slot (608) and the inner wall of the through hole (508), the two clamping plates (607) can be driven to move closer to each other and clamp the inclinometer. Step 3, lateral positioning: The drive motor (201) drives the drive shaft (202) and drive wheel (203) to rotate, thereby driving the conveyor belt (204) to perform transmission under the combined action of the driven wheel (206) and driven shaft (205) rotating along the upper surface of the second support column (102). Then, under the sliding cooperation between the inner wall of the sliding hole (304) and the outer wall of the support rod (103), the slider (301) can be linearly and laterally positioned to the required position. Step 4, vertical positioning: the first servo motor (305) drives the first rotating shaft (306) to rotate, thereby driving the first rotating plate (307) to rotate, which in turn drives the second circumferential rotating assembly (4) and the inclinometer to be positioned directly above the inclinometer hole. Step 5, directional alignment: the second servo motor (401) drives the second rotating shaft (402) to rotate, thereby driving the second rotating plate (403) to rotate, and thus aligning the pulleys on both sides of the inclinometer with the grooves on the inner wall of the inclinometer hole; Step 6, vertical positioning: the first electric hydraulic cylinder (501) drives the first hydraulic telescopic rod (502) to extend and slide, thereby driving the bearing plate (503) to move linearly downward in the vertical direction under the cooperation of the outer wall of the limiting rod (504) and the inner wall of the limiting hole (505), which in turn drives the lower end of the inclinometer to initially fall into the inclinometer hole; Step 7, release: The second hydraulic telescopic rod (602) is extended and slid by the operation of the second electric hydraulic cylinder (601), which can drive the connecting plate (603) away from the second electric hydraulic cylinder (601). Then, under the action of the rotation of the connecting rod (605) along the first connecting shaft (604), the rotation of the connecting rod (605) along the second connecting shaft (606), and the sliding action of the inner wall of the slot (608) and the inner wall of the through hole (508), the two clamping plates (607) can be driven away from each other and released from the inclinometer. Step 8, drop and measure inclinometer. The third servo motor (701) drives the third shaft (702) to rotate counterclockwise, which in turn drives the reel (703) to rotate counterclockwise, which in turn drives the cable (704) to unwind. This allows the inclinometer to perform inclinometer operation along the inclinometer hole. At the same time, the inclinometer data generated by the inclinometer is transmitted wirelessly to the external data center after passing through the connector (706), cable (704) and wireless transmission module (705). Step nine, rising and resetting: the third servo motor (701) drives the third rotating shaft (702) to rotate clockwise, which in turn drives the wire wheel (703) to rotate clockwise, which in turn drives the cable (704) to wind up. This allows the inclinometer to rise along the inclinometer hole to the ground. Then, through the sequential operation of the clamping assembly (6), the linear lifting assembly (5), the linear drive assembly (2), the first circumferential rotation assembly (3), the second circumferential rotation assembly (4), the linear lifting assembly (5), the clamping assembly (6), and the inclinometer traction assembly (7), the inclinometer can complete the inclinometer measurement of other inclinometer holes in the area, thereby completing the automated detection operation of ground subsidence in the coal mine goaf.
