A monitoring device applied to horizontal displacement refers to fig. 1, and comprises a frame body 1, a reference line 2, a wire clamping piece 3, a heavy hammer 4 and a base 5. A hanging piece 6 is arranged on the inner wall of the top of the frame body 1. The hanger 6 is provided with a support pulley 8. The base 5 is located between the wire clamp 3 and the support pulley 8. The base 5 is provided with a line pressing pulley 10. The lower edge of the line pressing pulley 10 is aligned with a limiting part of the line clamping member 3 for limiting the position of the reference line 2. The upper edge of the supporting pulley 8 is higher than the lower edge of the line pressing pulley 10. One end of the reference line 2 passes through the limiting part of the line clamping piece 3, and is connected with the heavy hammer 4 by sequentially passing through the line pressing pulley 10 and the supporting pulley 7. Four measuring rods 8 are arranged on the inner wall of the bottom of the frame body 1. The measuring rods 8 are connected with horizontal trays 9 which can slide up and down. The horizontal tray 9 is always kept parallel to the bottom of the frame body 1. The horizontal tray 9 is located right below the weight 4. Four measuring rods 8 are completely covered at the top of the frame body 1, so that rainwater is prevented from corroding the frame body. The outer wall of the measuring rod 8 is provided with a horizontal reading 87 from top to bottom. The reference line 2 is a steel wire rope made of steel wires.

Referring to fig. 2, one of the measuring rods 8 is provided with a rotary button 11 for driving the horizontal tray 9 to move up and down. A chute 81 with an opening at one side is arranged in the measuring rod 8 provided with the rotary button 11, and a screw 84 which rotates by itself is arranged in the chute 81. The upper end of the screw 84 is provided with a driven wheel 85. The output end of the rotary button 11 penetrates through the measuring rod 8 and is positioned in the sliding groove 81, and the output end of the rotary button 11 is connected with a driving wheel 86. The driving pulley 86 is engaged with the driven pulley 85. The screw 84 is rotatably connected with a base block 83, and the base block 83 is connected with the horizontal tray 9.

The slide rod 82 is slidably mounted with a base block 83. The base block 83 is connected to the horizontal tray 9.

When detecting the horizontal displacement of the hydraulic structure, first, the rotation button 11 is rotated to make the horizontal tray 9 slowly leave the weight 4, so that the weight 4 is completely in contact with the horizontal tray 9 without any force. After the datum line 2 is stably loaded, measuring horizontal displacement; after the measurement is completed, the rotating button 11 is rotated again to make the horizontal tray 9 slowly contact the weight 4 until the datum line 2 is in a completely relaxed state, and the reading of the measurement is finished. Generally, the tension wire method for each horizontal displacement of the hydraulic structure needs to perform two measurements to obtain an average value, so that the measurement process needs to be repeated twice, and after the final measurement is finished, the datum line 2 needs to be unloaded, so that the datum line 2 is in a loose state.
