[0002] Mining area refers to a coalfield or part of it that is uniformly planned and developed, including several mines or open-pit mines, with complete production processes, ground transportation, power supply, communication dispatching, production management and life service facilities. Its scope often depends on the scale of the ore deposit. Ground deformation in mining areas refers to the parts of high and steep terrain and landforms facing the sky. Due to mining activities on cliffs or at the foot of the mountain, the upper and lower mountains often crack and deform, and even collapse disasters occur. The characteristics of this type of collapse are that the cracks in the rock mass before the collapse and the rear edge boundary formed after the collapse often occur and develop along the original structural fracture surface or unloading fracture surface in the rock mass. The locations of common data acquisition equipment are mostly fixed, which makes multi-point monitoring inconvenient.

[0012] In addition, the present invention also provides a working method of a data acquisition device for monitoring surface deformation in a mining area, comprising the following steps: Step 1: When adjusting the height of both ends of the moving slide, remove the screws from the fastening holes and the inside of the threaded grooves to loosen the fixation of the lifting frame. At this time, the height of both ends of the moving slide can be adjusted by the equipment until the moving slide is adjusted to a suitable position and fixed with screws; Step 2: When detecting the deformation of the surface of the mining area, start the driving motor, and use the driving motor to drive the driving gear, the force gear, the driving shaft and the moving gear to rotate. At this time, the rotation of the moving gear will cooperate with the tooth groove, so that the moving frame moves along the moving slide, and the movement of the moving frame drives the collector to move.

When there is a distance between the bottom wall of the moving through hole and the moving slide, the threaded column is rotated to drive the upper block to move along the storage bin by the rotation of the threaded column. The inclined setting of the upper block can contact the bottom wall of the moving slide, thereby increasing the stability of the mobile frame when moving; Step 5. When the height of the wind-breaking frame needs to be adjusted, the threaded rod can be rotated to raise or lower the connecting frame, and the connecting frame can also be taken out through the outer convex groove.

The wind-breaking frame can break the wind when the collector moves, reduce the wind resistance of the collector when it moves, and improve the stability of the collector when it moves. The side slide rails and side sliders can not only further improve the stability of the mobile frame when it moves, but also share the weight pressure of the collector for the mobile frame, thereby increasing the load of the mobile frame; 2. The present invention adopts the arrangement of a mobile slide, a dispatching frame, a lifting slot and a work slot. When the surface of the mining area is rugged, the height of both ends of the mobile slide can be adjusted to adapt to the terrain of the mining area, thereby increasing the terrain adaptability of the equipment. The position of the lifting frame can be fixed by fastening holes and threaded grooves, and the height of the wind-breaking frame can be adjusted by threaded rods, so that the wind-breaking frame can be suitable for collectors of different lengths and models, so that collectors of different models can maintain good stability when in use; 3.

At this time, the upper top block will limit the movable through hole on the movable slide, so that the movable frame can move more smoothly. The difficulty of moving the movable frame can be reduced by arranging the driving motor. The speed change transmission can be formed by arranging the driving gear and the force-bearing gear, so that the power of the driving motor can more effectively drive the movable gear to rotate, thereby improving the moving efficiency of the movable frame.

[0019] Specific working process: the heights of both ends of the mobile slide 21 can be adjusted by the lifting and dispatching mechanism 3, the lifting frame 35 and the external plate 36. When detecting the surface deformation of the mining area, the driving mechanism 6 is used to drive the mobile gear 28 to rotate. At this time, the mobile gear 28 is meshed with the tooth groove 22, so that the mobile frame 23 moves along the mobile slide 21, and the movement of the mobile frame 23 drives the collector 24 to move.

9. A working method of a data acquisition device for monitoring ground deformation in a mining area applicable to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: When adjusting the height of the two ends of the movable slide (21), remove the screws from the fastening holes (34) and the inside of the threaded grooves, thereby loosening the fixation of the lifting frame (35). At this time, the height of the two ends of the movable slide (21) can be adjusted by using the equipment until the movable slide (21) is adjusted to a suitable position and fixed with screws; Step 2: When detecting the deformation of the surface of the mining area, the driving motor (61) is started, and the driving motor (61) is used to drive the driving gear (62), the force gear (64), the driving shaft (63) and the moving gear (28) to rotate. At this time, the rotation of the moving gear (28) will cooperate with the tooth groove (22), so that the moving frame (23) moves along the moving slide (21), and the movement of the moving frame (23) drives the collector (24) to move. The collector (24) is used to detect the deformation of the surface of the mining area, and when the moving frame (23) moves, the side slide block (27) will also move along the side slide rail (26); Step 3, the collector (24) includes a radar transmitting unit, a radar receiving unit and a processing unit, wherein the radar transmitting unit can transmit radar signals in real time when the mobile frame (23) moves, and the radar receiving unit can receive radar signals in real time, and then transmit the received radar signals to the processing unit for processing, and use the processing unit to draw the received radar signals into a three-dimensional topographic map, and record the three-dimensional topographic map data. When performing secondary mining area surface deformation monitoring, new radar signals will be received again, thereby generating new three-dimensional topographic map data. At this time, the processing unit will compare the three-dimensional topographic map data of the adjacent two sides to check the difference between the two three-dimensional topographic map data, and also has an interval comparison function, which can compare two three-dimensional topographic map data with a set interval time, and can also compare two three-dimensional topographic map data with a set number of intervals; Step 4: When the movable frame (23) and the collector (24) are moving, the wind-breaking frame (25) can be used to break the wind. When there is a distance between the bottom wall of the movable through hole and the movable slide (21), the threaded column (53) is rotated, and the rotation of the threaded column (53) is used to drive the upper top block (51) to move along the storage bin (52). The upper top block (51) is inclined so as to contact the bottom wall of the movable slide (21), thereby increasing the stability of the movable frame (23) when moving. Step 5: When the height of the wind-breaking frame (25) needs to be adjusted, the threaded rod (41) can be rotated, and the connecting frame (43) can be raised or lowered by the rotation of the threaded rod (41), and the connecting frame (43) can also be taken out through the outer convex groove (44).
