[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0028] Example: This application discloses a method for detecting bridge anti-collision piers, referring to... Figure 1 This includes the following steps: S1. Aerial photography by drones and high-resolution handheld cameras are used to conduct a comprehensive inspection of the appearance of the crash barriers, focusing on recording damaged areas and suspected impact marks. S2, multibeam echo sounding system and three-dimensional real-time sonar are used to accurately measure the spatial position of the crash barrier. At the same time, high-precision navigation is used for positioning and spatial position relationship map is drawn to ensure that the measurement accuracy reaches the centimeter level. S3, underwater exploration and high-frequency sonar are used to take pictures to conduct a comprehensive survey of the appearance of underwater steel pipe piles; S4. The detection device performs visual inspection of the crash barrier and conducts underwater investigation of the steel pipe piles under the tilted crash barrier. Divers use handheld high-frequency sonar to scan and locate any broken piles or abnormal deformations such as corners and wrinkles on the surface. S5. The testing device performs corrosion testing on the crash barrier. The tester uses a handheld cutting device to take samples from the broken pile, measure the thickness, and test the corrosion of the steel pipe pile.

[0029] This detection method combines multiple modern measurement techniques, allowing the detection results to corroborate and complement each other. Simultaneously, multi-source data fusion analysis leads to a more complete structural assessment of the crash barriers and a more accurate safety assessment. This effectively reduces errors during the detection process and improves the accuracy and precision of the results.

[0030] Reference Figure 1 The detection device includes a positioning component 1 and a detection component 2, which are divided into upper and lower layers. The positioning component 1 is located below the detection component 2. The positioning component 1 is used to clamp and position the crash barrier to be detected, effectively ensuring the stability of the detection component 2 during the detection process. After the positioning component 1 has positioned the crash barrier, the detection component 2 immediately begins to perform visual and corrosion inspections on the crash barrier. The positioning component 1 and the detection component 2 are integrally connected by a vertically placed connecting rod 3.

[0031] Specifically, refer to Figure 1 and Figure 2 The positioning component 1 includes a first clamp 11 and a second clamp 12. The first clamp 11 is used to clamp and position circular crash barriers, and the second clamp 12 is used to clamp and position square crash barriers. This allows the first clamp 11 and the second clamp 12 to clamp and position crash barriers of different structural shapes, thereby improving the overall adaptability of the positioning component 1 and facilitating safety inspection of crash barriers of different structural shapes. The first clamp 11 and the second clamp 12 are connected by a drive box 4. The drive box 4 contains a first drive component 5 and a second drive component 6. The first drive component 5 and the second drive component 6 are used to adjust the shape and size of the first clamp 11 and the second clamp 12, respectively. This allows the first clamp 11 and the second clamp 12 to adapt to crash barriers of different shapes and sizes, thereby improving the overall adaptability of the detection device. When faced with crash barriers of different shapes and sizes, there is no need to change the detection device, further improving the efficiency of the detection device in inspecting crash barriers.

[0032] At the same time, refer to Figure 1 and Figure 2The bottom of the drive box 4 is rotatably mounted with a base 7, and rotating the base 7 can adjust the position of the first clamp 11 and the second clamp 12.

[0033] Specifically, refer to Figure 1 and Figure 2 The detection component 2 includes a slide rail 21 and a sonar camera 22. The slide rail 21 is horizontally positioned above the drive box 4, and a connecting rod 3 is fixed between the slide rail 21 and the drive box 4, connecting the slide rail 21 and the drive box 4 into a single unit. The sonar camera 22 is slidably mounted on the slide rail 21. After the positioning component 1 positions the crash barrier, the sonar camera 22 slides on the slide rail 21 to complete the appearance and corrosion detection of the crash barrier. Specifically, the slide rail 21 has a semi-circular structure. When detecting the crash barrier, the two slide rails 21 are spliced ​​together as a single unit using corresponding clips to complete the detection of the crash barrier.

[0034] Specifically, the first clamp 11 has a curved arc-shaped structure for clamping the crash barrier. When clamping and positioning a circular crash barrier, two sets of first clamps 11 are used. The first drive assembly 5 adjusts the overall curvature of the first clamp 11 to accommodate crash barriers of different shapes and sizes. The second clamp 12 consists of two symmetrically arranged plates. When clamping and positioning a square crash barrier, two sets of second clamps 12 are used. The second drive assembly 6 adjusts the distance between the two rectangular plates of the second clamp 12 to accommodate crash barriers of different shapes and sizes.

[0035] Specifically, when clamping and positioning the corresponding crash barriers, after the two first clamps 11 or the two second clamps 12 are positioned, they are connected as a whole by corresponding buckles and bandages. After the crash barriers are inspected, the buckles and bandages can be released.

[0036] Specifically, refer to Figure 1 and Figure 2 The drive box 4 contains a first drive gear 8, a first rack 9, a second rack 10, and a first drive motor 13. The first drive motor 13 is fixed inside the drive box 4. The first drive gear 8 is connected to the first drive motor 13. The first drive gear 8 is vertically mounted and rotates using the first drive motor 13. The first rack 9 and the second rack 10 are both horizontally positioned and distributed on the upper and lower sides of the first drive gear 8. During rotation, the first drive gear 8 meshes with the first rack 9 and the second rack 10.

[0037] The first rack 9 and the second rack 10 are respectively connected to the first drive assembly 5 and the second drive assembly 6. The first rack 9 and the second rack 10 drive the first drive assembly 5 and the second drive assembly 6 respectively to adjust the shape and size of the first clamp 11 and the second clamp 12.

[0038] The first drive gear 8 has a smooth portion on one side and a toothed portion on the other side. When the toothed portion of the first drive gear 8 meshes with the first rack 9, the first drive gear 8 drives the first rack 9 to slide in the horizontal direction; when the toothed portion of the first drive gear 8 meshes with the second rack 10, the first drive gear 8 drives the second rack 10 to slide in the horizontal direction.

[0039] Specifically, refer to Figure 1 and Figure 2 The first drive assembly 5 includes a first drive plate 51, a drive rod 52, and a connector 53. The first drive plate 51 is vertically arranged, and its side wall is integrally connected to the first rack 9. The drive rod 52 is horizontally arranged, with one end integrally connected to the first drive plate 51 and the other end integrally connected to the connector 53. The connector 53 is located inside the first clamp 11, with the end of the drive rod 52 penetrating through the first clamp 11 and integrally connected to the connector 53. The end of the connector 53 away from the drive rod 52 is connected to the inner wall of the first clamp 11.

[0040] When adjusting the curvature of the first clamp 11, the first rack 9 drives the first drive plate 51 and the drive rod 52 to slide away from the first clamp 11. During the sliding process, the drive rod 52 drives the connector 53 to slide synchronously. During the sliding process, the connector 53 pulls the first clamp 11, and the curvature of the first clamp 11 is adjusted by the pulling force of the connector 53.

[0041] In this embodiment, both the connector 53 and the first clamp 11 are made of elastic material, which facilitates the deformation of the connector 53 and the first clamp 11.

[0042] Specifically, refer to Figure 1 and Figure 2 The second drive assembly 6 includes a second drive plate 61, a drive member 62, and two connecting plates 63. The second drive plate 61 is vertically arranged, and its sidewall is integrally connected to the second rack 10. The drive member 62 is horizontally arranged and welded to the sidewall of the second drive plate 61. The two connecting plates 63 are respectively connected to the two plates of the second clamp 12. The drive member 62 is used to drive the two connecting plates 63 to slide in a direction away from each other. During the sliding process, the two connecting plates 63 synchronously drive the two plates of the second clamp 12 to slide, thereby enabling the second clamp 12 to clamp and position anti-collision blocks of different sizes.

[0043] Specifically, refer to Figure 2 and Figure 3 Both ends of the driving component 62 are integrally formed with wedges 14, and the end of the connecting plate 63 near the driving component 62 is wedge-shaped, with the wedges 14 and the corresponding connecting plates 63 engaging in a wedge-shaped fit. During the sliding process of the driving component 62 driven by the second driving plate 61, the wedges 14 at both ends of the driving component 62 and the corresponding connecting plates 63 engage in a wedge-shaped fit, thereby causing the two connecting plates 63 to slide in a direction away from each other, thus enabling the second clamp 12 to clamp and position anti-collision blocks of different sizes.

[0044] Furthermore, referring to Figure 2 and Figure 3 Both connecting plates 63 are equipped with a return spring 15 on the side that is far apart from each other, and the return spring 15 is used to assist the second clamp 12 in resetting.

[0045] Specifically, refer to Figure 1 and Figure 4 A second drive motor 16 is installed on the side wall of the slide rail 21. The second drive motor 16 is covered by a corresponding waterproof cover. A second drive gear 17 is connected to the top of the second drive motor 16 in a horizontal direction. A toothed ring 18 is installed inside the slide rail 21 along its circumference. The side wall of the toothed ring 18 is toothed. The second drive gear 17 and the toothed ring 18 are meshed and connected. The sonar camera 22 is installed on the top of the toothed ring 18.

[0046] Specifically, when inspecting the crash barrier, the second drive motor 16 drives the second drive gear 17 to rotate. During the rotation of the second drive gear 17, it meshes with the gear ring 18 and drives the gear ring 18 to rotate. The gear ring 18 drives the sonar camera 22 to rotate on the slide rail 21, thereby completing the appearance and corrosion inspection of the crash barrier.

[0047] The implementation principle of the bridge anti-collision pier detection method in this application embodiment is as follows: S1. Aerial photography by drones and high-resolution handheld cameras are used to conduct a comprehensive inspection of the appearance of the crash barriers, focusing on recording damaged areas and suspected impact marks. S2, multibeam echo sounding system and three-dimensional real-time sonar are used to accurately measure the spatial position of the crash barrier. At the same time, high-precision navigation is used for positioning and spatial position relationship map is drawn to ensure that the measurement accuracy reaches the centimeter level. S3, underwater exploration and high-frequency sonar are used to take pictures to conduct a comprehensive survey of the appearance of underwater steel pipe piles; S4. The detection device performs visual inspection of the crash barrier and conducts underwater investigation of the steel pipe piles under the tilted crash barrier. Divers use handheld high-frequency sonar to scan and locate any broken piles or abnormal deformations such as corners and wrinkles on the surface. S5. The testing device performs corrosion testing on the crash barrier. The tester uses a handheld cutting device to take samples from the broken pile, measure the thickness, and test the corrosion of the steel pipe pile.

[0048] This detection method combines multiple modern measurement techniques, allowing the detection results to corroborate and complement each other. Simultaneously, multi-source data fusion analysis leads to a more complete structural assessment of the crash barriers and a more accurate safety assessment. This effectively reduces errors during the detection process and improves the accuracy and precision of the results.

[0049] The testing device includes a positioning component 1 and a testing component 2, which are divided into upper and lower layers. The positioning component 1 is located below the testing component 2. The positioning component 1 is used to clamp and position the crash barrier to be tested, effectively ensuring the stability of the testing component 2 during the testing process. After the positioning component 1 positions the crash barrier, the testing component 2 immediately begins to perform visual and corrosion inspections on the crash barrier. The positioning component 1 and the testing component 2 are integrally connected by a vertically placed connecting rod 3.

[0050] Specifically, the positioning component 1 includes a first clamp 11 and a second clamp 12. The first clamp 11 is used to clamp and position circular crash barriers, and the second clamp 12 is used to clamp and position square crash barriers. This allows the first clamp 11 and the second clamp 12 to clamp and position crash barriers of different structural shapes, thereby improving the overall adaptability of the positioning component 1 and facilitating safety inspection of crash barriers of different structural shapes. The first clamp 11 and the second clamp 12 are connected by a drive box 4. The drive box 4 contains a first drive component 5 and a second drive component 6. The first drive component 5 and the second drive component 6 are used to adjust the shape and size of the first clamp 11 and the second clamp 12, respectively. This allows the first clamp 11 and the second clamp 12 to adapt to crash barriers of different shapes and sizes, thereby improving the overall adaptability of the detection device. When faced with crash barriers of different shapes and sizes, there is no need to change the detection device, further improving the efficiency of the detection device in inspecting crash barriers.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
