Description

Technical Field

[0001] This utility model relates to the field of underwater bridge inspection technology, specifically to a comprehensive underwater pile foundation inspection device for bridges. Background Technology

[0002] Bridge pile foundations are the lowest part of a bridge in contact with the ground, and their performance has a crucial impact on the overall safety of the bridge. The underwater portion of bridge pile foundations is constantly subjected to erosion and water flow, often suffering more severe damage than the above-water portion. Because this damage is underwater, it is usually difficult to detect through routine inspections. Therefore, it is essential to regularly inspect underwater bridge pile foundations to comprehensively and accurately understand their safety status.

[0003] Currently, underwater bridge pile foundations are mainly inspected using methods such as diver observation, underwater robot inspection, and sonar inspection. Each method has its limitations. Diver observation requires personnel to dive underwater for close-up photography and exploration of the bridge pile foundations, making it highly susceptible to water quality, depth, and current speed, and demanding high levels of skill from the divers. While underwater robot inspection can examine bridge pile foundations in deeper waters, it struggles to hover at predetermined locations in turbulent conditions, hindering effective inspection. Furthermore, in complex underwater environments or when severe corrosion exposes reinforcing steel, the robot can easily become stuck. Sonar inspection is convenient and fast, but it is expensive, suffers from blind spots due to sound wave obstruction, and lacks the accuracy required for detecting cracks and other defects in bridge pile foundations. Additionally, the surface of underwater bridge pile foundations often harbors large amounts of algae and other aquatic organisms, which most inspection methods cannot clean, affecting subsequent inspection results. Therefore, the main problems in underwater pile foundation testing are limited underwater detection depth, inability to work properly in turbulent water or turbid water, underwater detection devices being easily stuck by exposed steel bars of bridge pile foundations, difficulty in achieving all-round, high-precision detection of pile foundation surfaces, and lack of equipment for cleaning pile foundation impurities.

[0038] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of the omnidirectional detection device for underwater bridge pile foundations.

[0039] Example 1

[0040] Combination Figures 1-8 As shown, this embodiment provides a comprehensive underwater pile foundation inspection device for bridges. The device adopts a double-layer layout, with the upper layer being a load-bearing and lifting device 1, and the lower layer being a multi-angle inspection device 2 and a cleaning device. The cleaning device is fixedly connected to the bottom of the multi-angle inspection device 2. The cleaning device includes multiple cleaning mechanisms 3, which are disposed at the bottom of the multi-angle inspection device 2.

[0041] The load-bearing and lifting device 1 is fixedly connected to the above-water part of the underwater pile foundation 4 of the bridge; the multi-angle detection device 2 and the cleaning device surround the wall of the underwater pile foundation 4 of the bridge to be inspected; the load-bearing and lifting device 1 drives the multi-angle detection device 2 and the cleaning device to move up and down along the axis of the underwater pile foundation 4 of the bridge.

[0042] During the descent of the multi-angle detection device 2 and the cleaning device, if the exposed steel bars of the pile foundation are encountered, the multi-angle detection device 2 can increase the distance between itself and the outer wall of the underwater pile foundation 4 to avoid being stuck. When the multi-angle detection device 2 drives the cleaning device to the required detection position of the underwater pile foundation 4, the cleaning device can clean the detection position. Then, the multi-angle detection device 2 reduces the distance between itself and the outer wall of the underwater pile foundation 4, thereby holding the underwater pile foundation 4 tightly to reduce the interference of water flow on the detection device. Finally, the multi-angle detection device 2 stops at the predetermined detection height to detect the underwater pile foundation.

[0043] Example 2

[0044] Combination Figures 1-8As shown, this embodiment provides a bridge underwater pile foundation all-round inspection device. The device adopts a double-layer layout. The upper layer is a load-bearing and lifting device 1, and the lower layer is a multi-angle inspection device 2 and a cleaning device. The cleaning device is fixedly connected to the bottom of the multi-angle inspection device 2. The cleaning device includes multiple cleaning mechanisms 3, which are equally spaced at the bottom of the multi-angle inspection device 2.

[0045] The load-bearing and lifting device 1 is fixedly connected to the above-water part of the underwater pile foundation 4 of the bridge by bolts 13; the multi-angle detection device 2 and the cleaning device surround the wall of the underwater pile foundation 4 of the bridge to be inspected; the load-bearing and lifting device 1 drives the multi-angle detection device 2 and the cleaning device to move up and down along the axis of the underwater pile foundation 4 of the bridge.

[0046] In this embodiment, combined with Figure 2 As shown, the load-bearing and lifting device 1 includes a load-bearing ring 11, a lifting device 12, bolt 13, hinge 14, and bolt 15. The load-bearing ring 11 is formed by splicing two semi-circular arc segments, which are connected by hinge 14 and bolt 15 respectively. The two semi-circular rings can rotate around the hinge 14 to open and close the load-bearing ring 11. Multiple bolts 13 are evenly spaced along the inner side of the load-bearing ring 11, and each bolt 13 penetrates... At least two bolts 13 are installed on the load-bearing ring 11. By tightening the bolts 13, the distance between the inner wall of the load-bearing ring 11 and the outer wall of the underwater pile foundation 4 of the bridge can be adjusted so that the end of the bolt 13 is in close contact with the outer wall of the underwater pile foundation 4 of the bridge, so as to adapt to the underwater pile foundation 4 of different diameters and achieve anchoring on the pile foundation surface; multiple lifting devices 12 are installed at equal intervals along the outer side of the load-bearing ring 11, and the number of lifting devices 12 is at least two.

[0047] In this embodiment, combined with Figure 3 As shown, the lifting device 12 includes a motor 121, a gear set 122, a lifting rope 123, a rotating rod 124, and a fixing device 125.

The rotating rod 124 is bolted to the lower part of the load-bearing ring 11 via bolts on the fixing device 125. The output shaft of the motor 121 is rotatably connected to the rotating rod 124 via the gear set 122. The lifting rope 123 is wound around the rotating rod 124. The lifting device 12 is connected to the multi-angle detection device 2 via the lifting rope 123. The motor 121 drives the gear set 122 to rotate the rotating rod 124, thereby raising and lowering the lifting rope 123, allowing the lifted multi-angle detection device 2 to reach the predetermined detection position of the underwater pile foundation 4 of the bridge.

[0048] In a further optimized embodiment, the gear set 122 includes a driving gear and a driven gear. The output shaft of the motor 121 is fixedly connected to the driving gear in the gear set 122, and one end of the rotating rod 124 is fixedly connected to the driven gear. Through the meshing transmission between the gears in the gear set 122, the motor drives the rotating rod 124 to rotate around its own axis. Since the lifting rope 123 is wound around the surface of the rotating rod 124, as the rotating rod 124 rotates, it drives the lifting rope 123 to be retracted and extended.

[0049] In this embodiment, combined with Figure 4 As shown, the multi-angle detection device 2 includes a detection ring 25, a hydraulic telescopic system 21, a sliding camera system 22, and a positioning ring 24. The detection ring 25 maintains a certain distance from the outer wall of the underwater bridge pile foundation 4. The detection ring 25 includes multiple arc-shaped hollow carriers 251 and telescopic plates 252. The arc-shaped hollow carriers 251 are connected by telescopic plates 252. The arc-shaped hollow carriers 251 are segmented hollow structures. Each arc-shaped hollow carrier 251 has a matching hydraulic telescopic system 21 inside its cavity. The hydraulic telescopic system 21 is connected to the telescopic plate 252 to adjust the length of the exposed section of the telescopic plate 252. Multiple positioning rings 24 are evenly spaced on the upper surface, and each positioning ring 24 is connected to a corresponding lifting device 12 via a lifting rope 123. Multiple sliding camera systems 22 are evenly spaced on the inner side of the detection ring 25. Multiple positioning rods 23 are evenly spaced along the circumference of the detection ring 25. Each positioning rod 23 has an external thread on its body and can rotate along the internal thread of the detection ring 25 to accommodate piles of different diameters. Each positioning rod 23 has a movable wheel 231 connected to its end. The end of the positioning rod 23 is connected to the movable wheel 231 via a horizontal metal rotating rod, and the movable wheel 231 can slide up or down along the surface of the pile.

[0050] In a further optimized embodiment, combined with Figure 5As shown, the hydraulic telescopic system 21 includes a hydraulic cylinder 211, a piston rod 212, a rotating shaft 213, a pulley 214, a slide rail 215, and a rubber baffle 216. The hydraulic cylinder 211 is fixedly installed inside the cavity of the arc-shaped hollow carrier 251. One end of the piston rod 212 is movably connected to the hydraulic cylinder 213, and the other end of the piston rod 212 is fixedly connected to the telescopic plate 252 via the rotating shaft 213. The slide rail 215 is installed on both sides of the inner wall of the cavity of the arc-shaped hollow carrier 251, and its arrangement matches the movement trajectory of the telescopic plate 252. The telescopic plate 252 is slidably connected to the slide rail 215 via the pulley 214. By driving the telescopic plate 252 along the slide rail 215 to reciprocate inside the cavity through the hydraulic cylinder 211, the length of the exposed section of the telescopic plate 252 can be adjusted, thereby making the overall diameter of the multi-angle detection device 2 adjustable. During testing, reducing the diameter of the multi-angle detection device 2 allows it to grip the underwater bridge pile foundation 4, minimizing interference from water flow. When encountering exposed rebar on the pile foundation, increasing the diameter of the multi-angle detection device 2 allows it to cross the exposed rebar area, preventing it from being stuck. A rubber baffle 216 is installed at the end of the slide rail 215, serving as a barrier and protective element.

[0051] In this implementation, combined with Figure 6 and Figure 7 As shown, the sliding camera system 22 includes a fisheye camera 222, a camera distance adjustment mechanism, and a camera angle adjustment mechanism. The fisheye camera 222 is mounted on the camera distance adjustment mechanism, which is connected to the camera angle adjustment mechanism. The camera angle adjustment mechanism is fixedly connected to the inner side of the detection ring 25.

[0052] In a further optimized embodiment, the camera distance adjustment mechanism includes an upper mounting platform 228 and a linear motor 226. The linear motor 226 is disposed inside the upper mounting platform 228, and one end of the fisheye camera 222 extends into the upper mounting platform 228 and is connected to the output end of the linear motor 226. By driving the fisheye camera 222 to reciprocate on the upper mounting platform 228 via the linear motor 226, the distance between the fisheye camera 222 and the detection position of the underwater bridge pile foundation 4 can be precisely adjusted, allowing it to approach the underwater bridge pile foundation 4 for clearer and more intuitive detection.

[0053] In a further optimized embodiment, the camera angle adjustment mechanism includes a slide rail 221, a drive assembly 223, a rubber baffle 224, pulleys 225, a rotating connecting bolt 227, and a lower sliding platform 229.

The drive assembly 223 includes a small motor and a propeller located inside the lower sliding platform 229. By starting the small motor, the propeller is driven to rotate, causing the pulleys 225 to drive the fisheye camera 222 to move back and forth along the slide rail 221, thereby realizing all-round detection of the underwater pile foundation 4 of the bridge. This device surrounds the underwater pile foundation 4 of the bridge with multiple fisheye cameras 222 distributed at equal intervals. Each fisheye camera 222 can slide along the slide rail 226 to adjust the observation angle and get close to the pile foundation for close observation, thereby realizing all-round, multi-angle, and high-precision detection of the underwater pile foundation 4 of the bridge.

[0054] In this implementation, combined with Figure 8 As shown, the cleaning mechanism 3 includes a mounting bracket 31, a fixing bolt 32, a rotating rod 33, an angle adjustment mechanism 34, and a cleaning plate 35.

The rotating rod 33 is connected to the inside of the mounting bracket 31 by the fixing bolt 32. The rotation angle of the rotating rod 33 around the central axis of the fixing bolt 32 is adjusted by turning the fixing bolt 32, thereby adjusting the up and down rotation angle of the rotating rod. The end of the rotating rod 33 is fixedly connected to the cleaning plate 35 by the angle adjustment mechanism 34. The cleaning plate 35 can be designed as a long arc to surround the outer wall of the underwater pile foundation 4 of the bridge, so as to achieve thorough cleaning of the outer wall of the underwater pile foundation 4 of the bridge.

[0055] In a further optimized embodiment, combined with Figure 8 As shown, the angle adjustment mechanism 34 includes a clamping column 341, a rotating shaft, a clamping assembly 342, and a clamping knob 343, wherein the rotating shaft is located in... Figure 8 As shown in the diagram, the clamping assembly 342 is connected to the protruding part of the cleaning plate 35 via a rotating shaft.
