[0001] The utility model relates to the field of water conservancy detection, in particular to a multi-angle crack detection device for water conservancy detection. Background Technique

[0002] Water conservancy detection generally refers to the quality detection of water conservancy projects. It is an inspection carried out by water conservancy project quality inspection units on physical buildings of water conservancy projects according to relevant national laws, regulations and standards. To ensure the safety of water conservancy project buildings such as dams and sluice gates, it is necessary to regularly check whether cracks occur.

[0003] In water conservancy projects, cracks in buildings are important hidden dangers affecting the safe operation of the projects. The existence of cracks will not only reduce the bearing capacity of the buildings, but may also cause serious problems such as leakage and structural damage. However, there are many deficiencies in the existing water conservancy crack detection devices. Traditional water conservancy crack detection devices mostly detect at fixed angles and are difficult to detect the complex structures of water conservancy facilities in all directions. For example, when detecting cracks in the dam body of a dam, for cracks in different positions, traditional equipment cannot directly detect them, and it is necessary to climb manually or use auxiliary tools to adjust the position, which is dangerous and inefficient. For this reason, we propose a multi-angle crack detection device for water conservancy detection to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , in the present utility model, a multi-angle crack detection device for water conservancy detection includes a square base 1. A horizontal adjustment member 5 is fixedly installed inside the square base 1. The upper surface of the horizontal adjustment member 5 is fixedly connected to a rotating member 3. The horizontal adjustment member 5 includes a rotating motor 501 fixedly installed on the inner wall of the square base 1. The output end of the rotating motor 501 is fixedly connected to a long lead screw 502. A nut plate 503 is threadedly connected to the outer surface of the long lead screw 502. The top end of the nut plate 503 penetrates through the square base 1 and is fixedly connected to the bottom surface of the rotating member 3. A square opening adapted to the nut plate 503 is formed on the upper surface of the square base 1. Two guiding grooves 6 are formed on the upper surface of the square base 1. A sliding support block 7 is slidably connected to the inside of each guiding groove 6. The top end of each sliding support block 7 is fixedly connected to the bottom surface of the rotating member 3. A transmission mechanism is composed of the rotating motor 501, the long lead screw 502, and the nut plate 503 of the horizontal adjustment member 5. The rotating motor 501 drives the long lead screw 502 to rotate, causing the nut plate 503 to move horizontally on the square base 1, thereby driving the rotating member 3 and the detection probe module 10 to adjust their positions in the horizontal direction, expanding the detection range, and enabling the detection of cracks at different horizontal positions of water conservancy facilities. Example: When detecting cracks in the bottom slab of a large sluice, since the bottom slab area is large, the horizontal adjustment member 5 is started. The rotating motor 501 drives the long lead screw 502 to rotate, and the nut plate 503 moves horizontally along the square opening, driving the rotating member 3 and the detection probe module 10 to move horizontally above the sluice bottom slab, and sequentially detecting different areas of the bottom slab to ensure full coverage of the entire detection area. The cooperation between the guiding groove 6 and the sliding support block 7 provides guidance and stable support for the horizontal movement of the rotating member 3, preventing the rotating member 3 from shifting or shaking during the movement, ensuring the accuracy and stability of the horizontal movement of the detection probe module 10, improving the detection accuracy, keeping the detection probe stable, and ensuring clear crack images and accurate measurement data.

[0026] The rotating member 3 includes a circular base 31. The inner walls of the circular base 31 are respectively fixedly connected with a driving motor 35 and an annular slide rail 32. A sliding support 33 is rotatably connected inside the annular slide rail 32. The top end of the sliding support 33 is fixedly connected with a connecting plate 34. The upper surface of the connecting plate 34 is fixedly connected with a support cylinder 4. The output end of the driving motor 35 is fixedly connected with a cross connecting rod 36, and the outer surface of the cross connecting rod 36 is fixedly connected with the inner wall of the sliding support 33. The inner bottom wall of the support cylinder 4 is fixedly installed with an electric push rod 8. The output end of the electric push rod 8 is fixedly connected with a cylinder 9. The top end of the cylinder 9 is fixedly installed with a detection probe module 10, constructing the core structure of the multi-angle crack detection device. The horizontal adjustment member 5 realizes the position adjustment in the horizontal direction, the rotating member 3 completes the rotation angle adjustment, and the electric push rod 8 and the cylinder 9 realize the vertical direction adjustment. The cooperation of each component enables the detection probe module 10 to adjust the position and angle in multiple dimensions, meeting the detection requirements of different parts of water conservancy facilities. Example: When detecting cracks, start the rotating motor 501 of the horizontal adjustment member 5 to drive the long lead screw 502 to rotate, so that the nut plate 503 pushes the rotating member 3 to move horizontally to a suitable position. Then start the driving motor 35, and the cross connecting rod 36 drives the sliding support 33 to rotate on the annular slide rail 32, adjusting the detection probe module 10 to an angle opposite to the crack. Finally, start the electric push rod 8 to push the cylinder 9 up or down, so that the detection probe module 10 approaches the crack for detection.

[0027] The detection probe module 10 includes a support frame 111 fixedly installed at the top end of the cylinder 9. The inner walls of the support frame 111 are respectively fixedly installed with a high-definition camera 112 and a laser distance sensor 113. The front surface of the square base 1 is respectively fixedly installed with a data acquisition and processing module 14 and a display 15. The high-definition camera 112 in the detection probe module 10 can clearly capture the crack image, and the laser distance sensor 113 can accurately measure parameters such as the width and depth of the crack. The data acquisition and processing module 14 collects and processes the detection data in real time, and the display 15 intuitively displays the detection results, providing accurate and comprehensive crack information for the detection personnel, facilitating the analysis and evaluation of the safety status of water conservancy facilities. Among them, the high-definition camera 112 is used to obtain the image information of the crack. A high-resolution industrial camera is adopted, and the resolution can reach 4K, which can clearly capture the surface morphology of the crack. The laser distance sensor 113 is used to measure the width of the crack. By emitting a laser beam to both sides of the crack, the crack width is calculated according to the reflection time, and the measurement accuracy can reach 0.01 mm.

[0028] A plurality of moving wheels 2 are fixedly installed on the bottom surface of the square base 1. Two of the moving wheels 2 are universal wheels and are equipped with braking mechanisms, and the other two are guide wheels. The moving wheels 2 are installed on the bottom surface of the square base 1, enabling the detection device to move easily at the site of water conservancy facilities, facilitating the inspectors to quickly transport the device to different detection locations, reducing the manual handling burden, and improving the flexibility and efficiency of the detection work. Two sliding frames 13 are fixedly connected to the outer surface of the cylinder 9. Two long convex strips 12 are fixedly connected to the inner wall of the support cylinder 4, and the long convex strips 12 are slidably connected to the sliding frames 13. The sliding connection between the long convex strips 12 and the sliding frames 13 provides guidance for the up and down movement of the cylinder 9, ensuring that the cylinder 9 rises and falls smoothly under the push of the electric push rod 8, enabling the detection probe module 10 to accurately reach the detection position, avoiding detection errors caused by shaking, and improving the reliability of the detection. A limiting ring 11 is fixedly connected to the outer surface of the cylinder 9, and the limiting ring 11 is located inside the support cylinder 4. The limiting ring 11 is installed on the outer surface of the cylinder 9 and inside the support cylinder 4, which can limit the movement range of the cylinder 9, prevent the electric push rod 8 from pushing the cylinder 9 to rise or fall excessively, avoid damage to the detection probe module 10 due to exceeding the reasonable position, and at the same time ensure that the detection probe is within the appropriate working range, ensuring the safe and stable progress of the detection work.

[0029] The working principle of the present utility model is:

[0030] When detecting cracks, the device can be moved to the use position. The rotary motor 501 can be started to drive the long lead screw 502 to rotate, so that under the action of the thread, it can drive the nut plate 503, the rotating member 3 and the support cylinder 4 to move horizontally. Then, according to the position of the crack to be detected, the drive motor 35 can be started to drive the cross link 36 and the sliding support 33 to rotate in the annular slide rail 32, so that when the sliding support 33 rotates, it drives the connecting plate 34 and the support cylinder 4 to rotate. When the support cylinder 4 rotates, it can drive the detection probe module 10 to rotate. After adjusting it to the appropriate orientation, the electric push rod 8 can be started to operate to push the cylinder 9 up and down. After adjusting the cylinder 9 and the detection probe module 10 to the appropriate positions, the high-definition camera 112 can clearly capture the crack image, and the laser ranging sensor 113 can accurately measure parameters such as the width and depth of the crack. The data acquisition and processing module 14 collects and processes the detection data in real time, and the display 15 intuitively displays the detection results, providing accurate and comprehensive crack information for the inspectors.
