Description

Technical Field

[0001] This utility model relates to the field of bridge pier detection technology, and more specifically, to a bridge pier scour detection device. Background Technology

[0002] More and more bridges are being built in geographical environments with undulating terrain and swift-flowing rivers. However, due to human factors such as over-development of hillsides and illegal sand and gravel mining, or natural factors such as rainstorms and floods, the actual embedment depth of the bridge piers in the riverbed changes, causing the free end of the pier to become longer. This reduces the effective friction area of ​​the pile foundation, resulting in insufficient foundation bearing capacity. This poses a serious threat to the safety of the bridge piers and abutments, and may even cause uneven settlement, tilting, or collapse of the bridge.

[0003] Chinese patent CN207570601U discloses a riverbed scour monitoring device for bridge piers, comprising a body, a walking mechanism, a moving part, a power supply device, a drive device, and a control system. This device enables the body to move freely within the monitoring area, is flexible and convenient, highly adaptable, expands the monitoring range, and reduces blind spots and loopholes in the monitoring process. However, the moving part structure in this patent does not have a dedicated mechanical arm structure for crossing railings, which is not conducive to detecting bridge piers with railings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-3 The present invention discloses a bridge pier scour detection device, comprising a mobile frame 1, an organism 2 at one end of the mobile frame 1, a hydraulic cylinder 11 at the other end of the mobile frame 1, a support frame 3 at the upper end of the hydraulic cylinder 11, a rotating frame 4 movably connected to the upper part of the support frame 3, an electric telescopic rod 5 movably connected to one end of the rotating frame 4, and a detection device 6 at the end of the electric telescopic rod 5.

[0022] Specifically, the body 2 is equipped with a microcontroller, a wireless transmission module, a drive controller, and a high-capacity lithium battery pack. The microcontroller is connected to the mobile frame 1, the rotating frame 4, the electric telescopic rod 5, the detection device 6, the wireless transmission module, the drive controller, and the high-capacity lithium battery pack, respectively, for controlling the operation of the device, data processing, and information transmission.

[0023] More specifically, the support frame 3 includes a base plate 31, side plates 32, and a worm gear 33. The worm gear 33 is fixedly connected between the side plates 32, and the lower end of the side plates 32 is fixedly connected to the base plate 31. The base plate 31 is fixedly connected to the output end of the hydraulic cylinder 11. The hydraulic cylinder 11 controls the overall up and down movement of the support frame 3, adjusting the overall height of the rotating frame 4. Sliding plates 41 are symmetrically arranged on both sides of the rotating frame 4. Sliding strips that are movably connected to the side plates 32 are provided on the sliding plates 41 to prevent the sliding plates 41 from colliding with the side plates. The side plate 32 is separated from the slide plate 41 by an arc-shaped limiting groove 321. The limiting groove 321 contacts the slide plate 41 through the arc surface. A worm gear 42 is movably connected inside the rotating frame 4. The worm gear 42 meshes with the worm wheel 33. A drive motor 43 is provided at one end of the worm gear 42. The drive motor 43 drives the worm gear 42 to rotate. The worm wheel 33 is a fixed structure. So the worm gear 42 rotates on its own axis and revolves around the central axis of the worm wheel 33, which drives the slide plate 41 to move along the side plate 32 and change the angle of the rotating frame 4.

[0024] Furthermore, a U-shaped frame 44 is fixedly connected to the surface of the rotating frame 4. One end of the U-shaped frame 44 is fixedly connected to the rotating frame 4, and the other end of the U-shaped frame 44 is movably connected to the hinge block 45. The hinge block 45 is movably connected to the electric telescopic rod 5. When the rotating frame 4 is in use, the U-shaped frame 44 is controlled to rotate to the opening facing downward. The U-shaped frame 44 crosses the bridge railing, and the bridge railing supports the U-shaped frame 44. With the support of the rotating frame 4 and the bridge railing, the position of the U-shaped frame 44 can be stabilized.

[0025] It is important to understand that the electric telescopic pole 5 is a waterproof telescopic pole. The end of the electric telescopic pole 5 connected to the hinge block 45 is fixedly connected to a handle 51. The handle 51 can be used to control the rotation of the electric telescopic pole 5 around the hinge block 45. Before use, the electric telescopic pole 5 is folded up and stored with one side resting on the rotating frame 4. After the rotating frame 4 rotates, the long end of the U-shaped frame 44 goes around to the outside of the bridge railing, and the electric telescopic pole 5 rests against the bridge railing. As the U-shaped frame 44 rotates, the electric telescopic pole 5 is slowly placed down, and the handle 51 is used to control the electric telescopic pole 5 to rotate downward around the hinge block 45. The electric telescopic pole 5 is set vertically under its own weight. Conversely, when storing the electric telescopic pole 5, the handle 51 is also used to control the storage of the electric telescopic pole 5.

[0026] In this embodiment, the detection device 6 includes a streamlined waterproof housing. Inside the housing are integrated a sonar detector, a pressure sensor, a turbidity sensor, and an inertial measurement unit. The top of the housing is connected to the electric telescopic rod 5 via a universal hinge, and the bottom of the housing serves as the sonar detection surface. Pressure sensing holes are located on the side walls of the housing. The pressure sensor assists in measuring water depth and cross-checks it with the riverbed depth measured by the sonar, improving the reliability of the scour depth data. The turbidity sensor determines water quality, providing a reference for interpreting sonar data. The inertial measurement unit can sense the verticality of the probe in real time, performing attitude compensation on the sonar data to ensure data accuracy.

[0027] Working process: After the device is in place, the microcontroller starts each action component sequentially according to the preset program. The hydraulic cylinder 11 extends, pushing the support frame 3 to rise as a whole, making its height exceed that of the bridge railing. The drive motor 43 is started, driving the worm gear 42 to rotate. While rotating on its own axis, the worm gear 42 revolves around the central axis of the worm wheel 33, thereby driving the entire rotating frame 4 and the U-shaped frame 44 on it to rotate slowly until the opening of the U-shaped frame 44 faces downward and crosses the bridge railing. At this time, the bridge railing is just supported within the U-shaped structure of the U-shaped frame 44. After the U-shaped frame 44 is in place, the operator controls the electric telescopic rod 5 to rotate around the hinge block 45. The device rotates downwards, causing it to approach a vertical position under its own weight. The microcontroller then activates the electric telescopic rod 5, extending it section by section to smoothly lower the end detection device 6 into the water under the bridge until it reaches the predetermined detection depth. Once the detection device 6 reaches the designated position, its internal sonar detector begins scanning the riverbed around the pier, acquiring point cloud data of the riverbed surface. The pressure sensor measures the water pressure at the current depth in real time and calculates the water depth data. The turbidity sensor monitors the turbidity of the water, and the inertial measurement unit monitors the attitude angle of the detection device 6 under the impact of the water flow in real time. All of this data is transmitted back to the microcontroller inside the machine body 2 in real time via cables. Through multi-sensor data fusion processing, a precise three-dimensional model of the scour pit around the pier and key information such as the maximum scour depth are finally generated.
