[0017] The following will be combined with specific embodiments and appendix Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0018] A device for observing the horizontal displacement of a dam 6 comprises an observation base 1 and a centering base 2 respectively arranged on both sides of the dam, and a plurality of measuring bases 3 arranged on the dam. In the initial setting state of the device, the measuring base 3, the observation base 1 and the centering base 2 need to be fixed on the same straight line. The observation base 1 is fixed on one side of the dam, and the observation base 1 needs to be deeply buried to prevent it from moving. A centering base 2 is fixed on the other side of the gate pier, and the centering base 2 is also deeply buried to prevent it from moving. A measuring base 3 is fixed on the gate pier where the line connecting the centering base 2 and the observation base 1 passes. An observation device 6 is fixedly connected to the seat 1, and a fixed target 4 is fixedly connected to the centering base 2. The observation device 6 can aim at the fixed target 4 and emit a visible laser beam to align with the fixed target 4, which can be used as a reference. If the gate pier moves, the moving direction and distance of the gate pier can be measured based on this reference. The judgment of the direction and distance requires the help of a mobile target 5 detachably connected to the measuring base 3. In the initial state, when the mobile target 5 is assembled to any observation device 6, the laser beam is facing the center position of the mobile target 5. When the mobile target 5 is reassembled after a period of time, it can be clearly displayed on the mobile target 5.

[0019] Preferably, the observation device 6 includes a base 61, which is a cylindrical structure. The base 61 is fixedly connected to the observation base 1, and an adjusting device 63 is rotatably connected to the base 61. The adjusting device 63 includes a U-shaped rotating frame 611. The bottom end of the U-shaped rotating frame 611 is provided with a cylindrical slot for rotatably connecting to the cylindrical base 61, and the U-shaped rotating frame 611 will be damped when it rotates relative to the base 61. The damping-related settings are existing technologies and are not repeated here. Through holes are correspondingly provided on the two arms of the U-shaped rotating frame 611, and a rotating frame 612 is rotatably connected in the through holes. The two ends of the rotating frame 612 are rotatably connected in the through holes. A telescope 613 is fixedly connected to the middle part of the rotating frame 612, and a laser emitter 62 is fixedly connected to the telescope 613. The telescope 613 and the laser emitter 62 are arranged parallel to each other, and the line of sight of the telescope 613 is parallel to the direction of the laser emitted by the laser emitter 62. , the laser landing point of the laser emitter 62 can be observed through the telescope 613, and an adjusting gear set 632 is also provided in the U-shaped rotating frame 611. The end of the rotating frame 612 located in the support arm of the U-shaped rotating frame 611 is fixedly connected to a fixed gear 631, and the fixed gear 631 is meshed with the adjusting gear set 632. The adjusting gear set 632 is a prior art. An adjusting knob 633 is rotatably connected to the support arm of the U-shaped rotating frame 611, and the adjusting knob 633 is meshed with the adjusting gear set 632. The adjusting gear set 632 adjusts the transmission speed of the adjusting knob 633 so that the rotation of the adjusting knob 633 can fine-tune the rotation of the rotating frame 612, which is convenient for reducing the difficulty of alignment when fine-tuning the laser emitter 62. One end of the adjusting knob 633 is a gear structure, which is meshed with the adjusting gear set 632, and the end is located in the support arm of the U-shaped rotating frame 611, and the other end extends out of the support arm of the U-shaped rotating frame 611, which is convenient for rotation operation.

[0020] Preferably, the fixed target mark 4 on the centering base 2 is in the shape of a plate, and a center guide pattern is drawn on the fixed target mark 4 to facilitate the observer to align the laser with the center position of the fixed target mark 4.

[0021] Preferably, a guide block 31 is provided on the top surface of the measuring base 3, and the guide block 31 is fixedly connected to the top surface of the measuring base 3. The movable target 5 includes a movable base 51, and a guide groove 52 is provided on the bottom surface of the movable base 51 corresponding to the guide block 31, which is used for the sliding connection between the movable target 5 and the measuring base 3. A limit block 32 is fixedly provided at the end of the guide block 31 to limit the movable target 5 so that it can be fixed to the same position each time it is connected. A reference plate 53 is fixedly connected to the movable base 51, and a two-dimensional coordinate reference system is drawn on the reference plate 53, which can facilitate reading when the laser point falls on any position of the reference plate 53, so that the results can be recorded.

[0022] Instructions for use: First, an observation base 1 and a centering base 2 are set on both sides of the dam, and an observation device 6 is set on the observation base. A fixed target 4 is set on the centering base 2, and then the laser emitter 62 is adjusted to track the center of the fixed target 4 through the adjustment device 63. Then, the measuring base 3 is fixed according to the path of the laser beam, so that when the mobile target 5 is assembled on any measuring base 3, the laser beam is located at the center of the mobile target 5. Then, observation is performed once every six months or a year. During the observation, the adjustment device 63 in the observation device 6 needs to be recalibrated, and the telescope 613 is used to align the laser beam with the center of the fixed target 4. Then, the mobile target 5 is assembled on the observation base 1 in turn, and the relative position of the laser beam on the reference sign 53 is recorded. The displacement distance of the gate pier can be obtained. Because the mobile target 5 is assembled manually and then the user stands on the side of the mobile target 5 for close observation, the observation result is more accurate and the error is small.
