Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, and in particular to a bridge pile foundation scour detection device. Background Technology

[0002] In the underwater pile foundation area of ​​highway bridges, floods and torrents can be monitored in real time to measure the scouring depth of the riverbed around the pile foundation, preventing structural hazards caused by foundation exposure; in the river crossing section of railway bridges, scouring changes can be tracked during the flood season to ensure the safety of train passage; in the pile foundation area of ​​cross-sea bridges, tides and waves can be monitored to measure the scouring of the pile foundation, adapting to complex marine environments.

[0003] In existing technologies, some detection devices reflect the scour depth by connecting to the pier. In sonar detection technology, single-beam sonar can acquire vertical cross-sectional images of underwater structures, while multi-beam sonar can generate three-dimensional images to present the relevant conditions. There are also devices that combine climbing equipment, telescopic probes, and penetration resistance probes to detect the morphology of scour pits.

[0004] However, in actual use, it is impossible to achieve precise positioning. In complex riverbeds such as soft soil, gravel, and rock, the claw body is difficult to conform to the terrain, has insufficient grip, and is easily affected by water flow and floats and shifts. The traditional fixed structure slips significantly, causing the detection position to sway, data to be distorted, and monitoring stability to be unreliable. It is also difficult to adapt to diverse riverbed environments. In order to address the above problems, a bridge pile foundation scour detection device is proposed. Utility Model Content

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the connecting plate is moved by the telescopic rod, which in turn moves the connecting rod and the connecting plate, which in turn moves the follower rod and the gripper, so that the gripper body can fit into various riverbeds such as soft soil, sand, gravel and rock, adapt to complex terrain, enhance grip, resist water flow impact, prevent floating and displacement, solve the problem of traditional fixed structures being prone to slipping in complex riverbeds, ensure detection stability, and facilitate efficient monitoring.

[0035] The positioning mechanism includes a follower plate 7, which is a rectangular plate that can slide up and down inside the main control box 6. The follower plate 7 is externally slidably connected to the inside of the main control box 6. A positioning block 8, a square block structure, is fixedly connected to the outside of the follower plate 7 and is fixed to the bottom of the follower plate 7 for mounting positioning components. An infrared rangefinder 9, a square box structure, is fixedly connected to the outside of the positioning block 8 and is mounted on the side of the positioning block 8. The infrared rangefinder 9 can emit and receive infrared signals to measure distance. A telescopic rod 10 is fixedly connected inside the positioning block 8. The cylindrical rod body can extend and retract along the axial direction to change its length. Multiple connecting plates 11 are fixedly connected to the outside of the telescopic rod 10. Support components are fixedly connected to the outside of the connecting plates 11. Multiple grippers 15 are rotatably connected inside the positioning block 8. The grippers 15 are arc-shaped plate structures. One end is rotatably connected to the inside of the positioning block 8, and the other end can be tightened inward or opened outward. Multiple buffer components are fixedly connected inside the main control box 6. The support components include connecting rods 12. The connecting rods 12 are fixedly connected to the inside of the connecting plates 11. Connecting plates 13 are fixedly connected to the outside of the connecting rods 12.

[0036] The connecting plate 13 is a rectangular plate that can move synchronously with the connecting rod 12. Follower rods 14 are fixedly connected to the left and right sides of the connecting plate 13. The buffer assembly includes a support rod 16, which is a cylindrical rod that is vertically fixed inside the main control box 6. The outside of the support rod 16 is fixedly connected to the inside of the main control box 6. A buffer rod 17 is fixedly connected to the outside of the support rod 16. The buffer rod 17 is a cylindrical rod that is sleeved on the outside of the support rod 16 and can slide along the axial direction of the support rod 16. A buffer spring 18 is sleeved on the outside of the buffer rod 17. The buffer spring 18 is a spiral spring that is in an extended state in its natural state. A connecting block 19 is fixedly connected to the outside of the buffer spring 18. A monitoring sensor 20 is fixedly connected to the outside of the follower plate 7. The monitoring sensor 20 is a small columnar structure that is evenly distributed on the edge of the follower plate 7 and can detect parameters such as water flow speed and flushing depth.

[0037] Reference Figure 1 , Figure 3 and Figure 5 The adjustment mechanism includes a hollow plate 21, which is fixedly connected to the inside of the main control box 6. A rack plate 22 is slidably connected inside the hollow plate 21. The rack plate 22 is a rectangular plate with uniform toothed protrusions on one side surface. It can slide horizontally along the length direction inside the hollow plate 21. Slide grooves 23 are provided on the left and right sides of the hollow plate 21. The slide grooves 23 are rectangular grooves that run through the hollow plate 21 along its length direction. The width of the grooves matches the width of the follower block 24. The follower block 24 is fixedly connected to the outside of the rack plate 22. The follower block 24 is a square block structure that is vertically fixed to the two sides of the rack plate 22 and can move synchronously with the rack plate 22. A waterproof motor 25 is fixedly connected inside the main control box 6. The waterproof motor 25 is a cylindrical shell structure with its output shaft facing the rack plate 22. It can operate stably in an underwater environment. The follower block 24 is slidably connected to the outside of the slide groove 23.

[0038] When the rack plate 22 slides, the follower block 24 slides synchronously along the slide groove 23, guiding the movement of the rack plate 22. The drive end of the waterproof motor 25 is fixedly connected to a transmission rod 26. The transmission rod 26 is a cylindrical rod, one end of which is fixedly coaxially with the output shaft of the waterproof motor 25, and the other end extends toward the rack plate 22. A gear 27 is fixedly connected to the outside of the transmission rod 26. The gear 27 is a circular wheel with teeth that mesh with the tooth-like protrusions of the rack plate 22. It can rotate synchronously with the transmission rod 26 and drive the rack plate 22 to slide. Multiple main control boxes 6 are fixedly connected to the bottom of the support plate 5. The follower plate 7 is fixedly connected to the outside of the follower block 24. The top of the follower plate 7 is connected to the bottom of the rack plate 22. It can move synchronously along the follower block 24 under the drive of the rack plate 22, thereby adjusting the detection position of the monitoring sensor 20 and the infrared rangefinder 9.

[0039] Working principle: The positioning mechanism at the bottom of the main control box 6 is activated, causing the follower plate 7 to slide up and down inside the main control box 6, which in turn moves the positioning block 8 at the bottom of the follower plate 7. The infrared rangefinder 9 on the side of the positioning block 8 emits and receives infrared signals to measure the distance. At the same time, the telescopic rod 10 drives the connecting plate 11 to move, which in turn drives the connecting plate 13 to move synchronously through the connecting rod 12. This causes the follower rods 14 on the left and right sides of the connecting plate 13 to unfold to the sides and contact the riverbed. The arc-shaped plate-shaped claw 15 inside the positioning block 8 is rotated at one end and tightened inward at the other end, which works with the support components to achieve precise positioning.

[0040] The waterproof motor 25 drives the transmission rod 26 to rotate, which in turn drives the external gear 27 to rotate. This causes the gear 27 to mesh with the toothed protrusions of the rack plate 22 inside the hollow plate 21, pushing the rack plate 22 to slide along its length. This causes the rack plate 22 to drive the follower block 24 to move synchronously along the sliding grooves 23 on both sides of the hollow plate 21. The follower plate 7 moves with the follower block 24, thereby adjusting the detection position of the monitoring sensor 20 and the infrared rangefinder 9, and realizing comprehensive detection of the scour of the bridge pile foundation.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
