[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a road surface settlement monitoring device, including a base plate 1, a fixing rod 3 and a fixing screw 2 are fixedly arranged at the top and bottom center positions of the base plate 1 respectively, monitoring mechanisms are arranged on both sides of the bottom of the base plate 1 through movable plates 5, one end of the movable plate 5 is movably mounted on both sides of the top of the base plate 1 through a torsion spring rotating shaft, a mounting groove 6 is opened inside the movable plate 5, the monitoring mechanism includes a movable rod 7 and a sliding rod 8, the movable rod 7 is rotatably mounted inside the mounting groove 6 through an axle rod, and by rotating the movable plate 5, the movable plate 5 can drive the monitoring mechanism to rotate toward the position of the fixed rod 3 through the mounting groove 6, which can reduce the volume of the device and facilitate the storage and carrying of the device. By arranging the monitoring mechanisms on both sides, the monitoring range of the device can be improved, and the practicability is high.

[0022] In this embodiment, the movable rod 7 is a square rod, a sliding hole is opened inside the movable rod 7, the sliding rod 8 is slidably installed inside the sliding hole, the top and bottom ends of the sliding rod 8 are fixedly installed with fixed plates 10, and the fixed plates 10 are respectively arranged on the top and bottom ends of the movable rod 7. A scale 9 is opened on the outer wall of the top end of the sliding rod 8. The sliding rod 8 slides inside the movable rod 7 through the sliding hole, which is convenient for observing the downward movement of the sliding rod 8 and the scale 9, thereby monitoring the road surface settlement.

[0023] In this embodiment, a top plate 4 is fixedly installed on the top of the fixed rod 3, and a limiting mechanism is arranged inside the top plate 4. The limiting mechanism includes a limiting frame 11. The limiting frame 11 is in a "U" shape. Both ends of the limiting frame 11 are slidingly installed inside the top plate 4. A spring 12 is fixedly installed between the top of the top plate 4 and the limiting frame 11. The bottoms of both ends of the limiting frame 11 are arranged below the top plate 4. Under the pulling force of the spring 12, the bottom end of the limiting frame 11 can be blocked on the outside of the movable plate 5, so that the movable plate 5 and the monitoring mechanism can be folded and stored, thereby reducing the volume of the device.

[0024] When using the road surface settlement monitoring device, the device is inserted into the monitoring point on the road surface through the fixing screw 2, so that the bottom of the bottom plate 1 contacts the top of the road surface, and the device can be fixed, and the two ends of the limit frame 11 are pushed upward so that the top of the limit frame 11 moves out from the inside of the top plate 4, and the limit frame 11 is pulled upward, the limit frame 11 stretches the spring 12, and the two ends of the limit frame 11 move away from the two sides of the movable plate 5. The movable plate 5 rotates in the direction away from the fixed rod 3 under the torsion of the torsion spring shaft. At the same time, the movable plate 5 drives the movable rod 7 and the sliding rod 8 through the mounting groove 6. The movable plate 5 is in a state parallel to the road surface. A hole is dug in the road surface and the sliding rod 8 slides inside the movable rod 7 so that the bottom end of the scale 9 is aligned with the top of the movable rod 7. The bottom end of the sliding rod 8 is buried in the road surface through the fixing plate 10 or directly contacts the top of the road surface. By setting the movable rod 7 and the sliding rod 8, two points can be monitored at the same time, the monitoring range is large, and the settlement monitoring can be carried out by the device itself, without the need for additional equipment, and the practicability is high; when the road surface settles, the top height of the road surface drops, which will cause the sliding rod 8 and the scale 9 to move downward with the road surface, and the scale 9 corresponding to the top of the movable rod 7 changes, thereby monitoring the road surface settlement; by rotating the movable plate 5, the movable plate 5 drives the movable rod 7 and the sliding rod 8 through the mounting groove 6 and the shaft rod, so that the movable plate 5 and the monitoring mechanism are close to the fixed rod 3 and adjusted between the bottom plate 1 and the top plate 4, which can reduce the volume of the device and facilitate the carrying of the device; the limit frame 11 moves downward under the pulling force of the spring 12 and blocks the outside of the movable plate 5, so that the movable plate 5 can be limited and the stability of the movable plate 5 is improved.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
