[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] During water level monitoring, the floating plate naturally falls under the action of gravity, and the floating plate is laterally limited under the action of the first slide bar. The floating plate floats when it contacts the water surface in the dam body. The floating plate can float adaptively with the change of water level. The change of water level is monitored by the liquid level sensor at the bottom of the floating plate, which is convenient and fast.

[0013] During settlement monitoring, the cross plate is located on the top surface of the dam body. When the dam body settles, the cross plate drops under the action of gravity. Since the weight of the cross plate is greater than the elastic force of the reset spring, the card slot on the side wall of the cross plate squeezes the end inclined surface of the card column, and the card column slides in the side tube and squeezes the reset spring. The card column drives the movable rod to slide horizontally in the fixed plate, and the other end of the movable rod moves horizontally above the moving plate.

[0014] When monitoring different positions of the dam body, the threaded rod is rotated, and when the movable plate moves against the inclined surface of the end of the movable rod, the movable plate continues to move upward, pushing the movable rod upward and sliding upward in the movable groove of the side wall of the inner cylinder, so that the clamping column is stuck in the clamping groove of the side wall of the second slide rod and cannot move. The second slide rod drives the bottom cross plate to separate from the top surface of the dam body, and the outer cylinder drives the connecting rod and the positioning column to move upward synchronously, and the positioning column moves out of the positioning groove at the top of the slide rail, thereby completing the adjustment of monitoring of different positions of the dam body.

A reset spring 22 located on the outside of the movable rod 20 is fixedly connected between the fixing plate 21 and the clamping column 18.

A positioning column 27 penetrating into the top of the slide rail 5 is fixedly connected to the end of the connecting rod 26. A movable groove slidably matched with the connecting rod 26 and the positioning column 27 is provided inside the box body 7. Positioning grooves 28 matching with the bottom of the positioning column 27 are provided at equal intervals at the top of the slide rail 5.

[0027] The ends of the clamping column 18 and the movable rod 20 are both arranged as inclined structures, and the side wall of the inner cylinder 15 is provided with a sliding groove which is slidably matched with the movable rod 20 .

[0028] The adjustment assembly includes a threaded rod 23 rotatably connected to the top of the support plate 9, the threaded rod 23 is located at the inner center of the inner cylinder 15, and the movable rod 20 is located on one side of the threaded rod 23, the top of the threaded rod 23 extends to the top of the outer cylinder 16, and the outer wall of the threaded rod 23 is located at the bottom of the movable rod 20 and is provided with a movable disk 24 threadedly matched with it, and the top of the support plate 9 is fixedly connected to a limit rod 25 that slides with the movable disk 24.

[0029] Working principle: When using the dam settlement monitoring device, first, the fixed base 4 is always fixed on the top of the base 1. When monitoring the water level, the floating plate 11 falls naturally under the action of gravity, and the floating plate 11 is laterally limited under the action of the first slide bar 10. The floating plate 11 floats when it contacts the water surface in the dam body 3. The floating plate 11 can float adaptively with the change of the water level, and the change of the water level is monitored by the liquid level sensor 12 at the bottom of the floating plate 11;

[0030] When monitoring the settlement of the dam body 3, the cross plate 14 is located on the top surface of the dam body 3. When the dam body 3 settles, the cross plate 14 drops under the action of gravity. Since the weight of the cross plate 14 is greater than the elastic force of the reset spring 22, the card slot 19 on the side wall of the cross plate 14 squeezes the end inclined surface of the card column 18, and the card column 18 slides in the side tube 17 and squeezes the reset spring 22. The card column 18 drives the movable rod 20 to slide horizontally in the fixed plate 21, and the other end of the movable rod 20 moves horizontally above the movable plate 24. The cross plate 14 drives the second slide bar 13 to slide longitudinally in the support plate 9, so that the displacement change of the cross plate 14 is observed through the scale bar on the outer wall of the second slide bar 13, and the data of the settlement of the dam body 3 is obtained;

[0031] When it is necessary to monitor different positions of the dam body 3, the threaded rod 23 is rotated, and the threaded rod 23 drives the movable plate 24 to move longitudinally. The movable plate 24 slides on the outer wall of the limit rod 25 to limit the position. When the movable plate 24 moves to resist the inclined surface at the end of the movable rod 20, the movable plate 24 continues to move upward, pushing the movable rod 20 to move upward and slide upward in the movable groove of the side wall of the inner cylinder 15. The movable rod 20 is limited at this time, so that the clamping column 18 is stuck in the clamping groove 19 of the side wall of the second slide bar 13 and cannot move. Therefore, the movable rod 20 moves upward, the second slide bar 13, the side cylinder 17 and the outer cylinder 16 move upward synchronously, and the second slide bar 13 drives the bottom cross plate 14 to separate from the top surface of the dam body 3. At the same time, the outer cylinder 16 drives the connecting rod 26, the positioning column 18 and the outer cylinder 16 to move upward. 27 moves up synchronously, and the positioning column 27 moves out of the positioning groove 28 on the top of the slide rail 5. At this time, the box body 7 can be pushed, and the box body 7 slides on the outside of the slide rail 5 through the sliding member 6 to move, and the pulley 8 at the bottom of the box body 7 rolls on the top of the fixed base 4 to reduce the resistance. Since the cross plate 14 is separated from the top surface of the dam body 3, the floating plate 11 floats on the water surface, so that the resistance of the box body 7 is small when it moves. After the box body 7 moves to the specified position, the threaded rod 23 is rotated in the opposite direction, and the floating plate 11 floats on the water surface under the action of buoyancy, and the cross plate 14 contacts the top surface of the dam body 3 again under the action of gravity for monitoring, and the positioning column 27 is reset and snapped into the corresponding positioning groove 28 on the top of the slide rail 5, thereby completing the adjustment of the monitoring of different positions of the dam body 3.
