Description

Technical Field

[0001] This utility model relates to the field of geological disaster prevention and control technology, and in particular to a device for detecting the depth of cracks at potential geological disaster sites. Background Technology

[0002] In geological disaster prevention and control, detecting the depth of cracks at potential disaster sites is a crucial task. Accurately obtaining crack depth information helps assess the severity of potential disasters and provides key information for subsequent prevention and control measures.

[0003] Regarding equipment support, most existing testing equipment lacks effective support structures. When ground conditions are uneven, the equipment is difficult to place stably and is prone to shaking or even tipping over during testing, which not only affects the accuracy of the test data but may also damage the equipment. Even if some equipment is equipped with support structures, their operation is complex, requiring a significant amount of time and effort to deploy and adjust, and they cannot quickly adapt to different ground conditions, thus reducing the efficiency of testing work.

[0004] In addition, existing testing equipment is not convenient enough to adjust the height of the testing components, making it difficult to accurately adjust the testing components to the appropriate height, which limits the applicability of the equipment and brings many inconveniences to the testing process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing detection equipment, such as the lack of effective support structures and the inconvenience of adjusting the height of detection components. This invention proposes a crack depth detection device for potential geological hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for detecting the depth of cracks at potential geological disaster sites includes a support main board, an upper mounting plate fixedly connected to the top of the support main board, a fixed vertical plate fixedly connected to the top of the upper mounting plate, a strip-shaped groove on one side of the fixed vertical plate, multiple sliders slidably connected inside the strip-shaped groove, an L-shaped plate II, an L-shaped plate I and a fixed slide rail fixedly connected to one side of the sliders, a camera fixedly connected to one side of the L-shaped plate II, a supplementary light fixedly connected to one side of the L-shaped plate I, and a detection component provided on one side of the fixed slide rail.

[0008] Support components are provided on both sides of the supporting motherboard. The camera and fill light work together to capture and record the crack. The detection component detects the crack depth by ultrasonic reflection. The two methods complement each other to obtain accurate and comprehensive crack depth information.

[0009] In one possible design, the detection component includes a sliding sleeve plate slidably connected to one side of a fixed slide rail. An L-shaped plate III is fixedly connected to one side of the sliding sleeve plate, and a crack depth tester is fixedly connected to the bottom of the L-shaped plate III. The sliding sleeve plate slides along the fixed slide rail to adjust the position of the crack depth tester, thereby enabling multi-position monitoring of cracks.

[0010] In one possible design, the support assembly includes a U-shaped plate fixedly connected to one side of the support main board, with a rotating shaft rotatably connected inside the U-shaped plate. A support side plate is fixedly sleeved on the outer wall of the rotating shaft, and the support side plate can rotate and unfold around the rotating shaft to provide stable support when the ground is uneven.

[0011] In one possible design, the support side plate has a threaded hole inside, and a threaded rod is threadedly connected inside the threaded hole. An adjusting block is fixedly connected to the top of the threaded rod, and a frustum block is fixedly connected to the bottom of the threaded rod. Rotating the adjusting block causes the threaded rod to rotate, which in turn moves the frustum block up and down, thus adjusting the level of the device according to the terrain.

[0012] In one possible design, the bottom of the upper mounting plate has a circular groove and two rectangular holes. A rotating circular plate is rotatably connected inside the circular groove. A rotating lever is fixedly connected to the outer wall of the rotating circular plate. An inclined plate is fixedly connected to one side bottom of the rotating lever. A rubber block is fixedly connected to the bottom of the rotating lever. Rotating the rotating lever causes the inclined plate to move, thereby releasing or locking the braking state of the supporting side plate.

[0013] In one possible design, the L-shaped plate II, L-shaped plate I, and fixed slide rail are all provided with strip-shaped holes. The slider is internally threaded with a fixing screw. The fixing screw cooperates with the strip-shaped hole. Tightening the fixing screw fixes the slider in the strip-shaped groove to the required height, thereby adjusting the height of the detection component.

[0014] In this application, during use, the support motherboard can be placed directly near the crack. The depth of the crack can be captured by the camera and supplementary light above. The crack depth tester can detect the crack depth through ultrasonic wave reflection. The relative position of the crack depth tester can be adjusted by sliding the sliding plate on the side of the fixed slide rail, and multiple monitoring can be performed. The slider can be limited to a suitable height by fixing screws, thereby adjusting the height of the fixed slide rail, L-shaped plate II and L-shaped plate I, increasing the applicability of the device and facilitating the detection process.

[0015] When the ground conditions are not stable for the installation, the support side plates on both sides can be rotated and unfolded. First, the rotating lever needs to be rotated. Rotating the lever will cause the inclined plate and the rotating circular plate to rotate, allowing the inclined plate to move out of the gap between the U-shaped plate and the support side plate. At this point, the braking state of the support side plate is released, and the support side plate can be flipped flat. After flattening, rotate the rotating lever again, causing it to move above the support side plate and engage the rubber block inside the support side plate to brake it. After the support side plate is flipped, the adjusting block can be rotated. The adjusting block drives the threaded rod to rotate, and the threaded rod drives the frustum block to move up and down. This allows the device to be leveled according to the terrain, facilitating subsequent testing.

[0016] Beneficial effects: By combining a camera and a supplementary light, the crack depth can be captured and recorded. At the same time, a crack depth tester can be used to detect the crack depth through ultrasonic reflection. The two methods complement each other, which can obtain more accurate and comprehensive crack depth information and improve the reliability of the test results.

[0017] The sliding plate can slide on the side of the fixed slide rail, which can easily adjust the relative position of the crack depth tester, realize multi-position monitoring of cracks, expand the detection range, and obtain richer crack depth data.

[0018] When the ground is uneven, the support side plates on both sides can be rotated and unfolded. First, rotate the rotating lever to rotate the inclined plate and the rotating circular plate, causing the inclined plate to move out of the gap between the U-shaped plate and the support side plate, releasing the braking state of the support side plate, and then flipping it flat. After flattening, rotate the rotating lever again to make the rubber block engage inside the support side plate for braking. Then, by rotating the adjusting block, the threaded rod and the frustum block can be moved up and down, allowing the device to be leveled according to the terrain, ensuring the stability of the equipment under complex ground conditions. The operation process is simple and quick, improving the efficiency of the testing work.

[0019] By using the fixing screws in conjunction with the strip holes and strip grooves, the slider can be limited to a suitable height, thereby adjusting the height of the fixing slide rail, L-shaped plate II and L-shaped plate I, expanding the applicability of the device and facilitating the testing process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figure 1-7 The specific implementation method of a crack depth detection device for potential geological disaster sites is as follows:

[0030] The crack depth detection equipment for potential geological disaster sites mainly consists of a support main board 1, an upper mounting plate 17, a fixed vertical plate 8, a slider 14, an L-shaped plate II 7, an L-shaped plate I 6, a fixed slide rail 5, a camera 9, a supplementary light 10, detection components, and support components. Among them, the support main board 1, as the basic load-bearing component of the entire equipment, is made of high-strength aluminum alloy to ensure the structural stability and durability of the equipment in complex field environments.

[0031] A top mounting plate 17 is fixedly installed on the top of the main support plate 1. The top mounting plate 17 is made of engineering plastic, which is lightweight and high-strength. A fixed vertical plate 8 is fixedly installed on the top of the top mounting plate 17. A strip groove 15 is opened on one side of the fixed vertical plate 8, and three sliders 14 are slidably connected inside the strip groove 15. An L-shaped plate II 7, an L-shaped plate I 6, and a fixed slide rail 5 are respectively fixedly installed on one side of the three sliders 14. A camera 9 is fixedly installed on one side of the L-shaped plate II 7, and a supplementary light 10 is fixedly installed on one side of the L-shaped plate I 6. The camera 9 and the supplementary light 10 work together. In use, the main support plate 1 can be placed directly near the crack, and the depth of the crack can be photographed by the camera 9 and the supplementary light 10 to obtain intuitive image information of the crack, providing a basis for subsequent analysis.

[0032] A detection component for detecting crack depth is installed on one side of the fixed slide rail 5. The detection component includes a sliding sleeve 4 slidably connected to one side of the fixed slide rail 5, an L-shaped plate Ⅲ11 fixedly mounted on one side of the sliding sleeve 4, and a crack depth tester 3 fixedly mounted on the bottom of the L-shaped plate Ⅲ11. By sliding the sliding sleeve 4 along the side of the fixed slide rail 5, the relative position of the crack depth tester 3 can be adjusted for multiple monitoring operations. The crack depth tester 3 utilizes the principle of ultrasonic reflection, emitting ultrasonic waves into the crack and receiving the reflected waves. Based on information such as the time difference of the reflected waves, the crack depth is calculated, thereby achieving accurate detection of crack depth.

[0033] Support components for supporting the device are provided on both sides of the main support board 1. The support components include a U-shaped plate 26 fixedly installed on one side of the main support board 1, a rotating shaft 27 rotatably connected inside the U-shaped plate 26, and a support side plate 2 fixedly sleeved on the outer wall of the rotating shaft 27. When the ground conditions are not stable, the support side plates 2 on both sides can be rotated and unfolded. It is necessary to first rotate the rotating plate 23. A circular groove 25 is opened at the middle of the bottom of the upper mounting plate 17, and two rectangular holes 24 are centrally symmetrically opened on both sides. The two rectangular holes 24 are connected to the circular groove 25. A rotating circular plate 22 is rotatably connected inside the circular groove 25. Two centrally symmetrical rotating plates 23 are fixedly connected to the outer wall of the rotating circular plate 22. An inclined plate 20 is fixedly installed on the bottom of one side of the rotating plate 23, and a rubber block 21 is fixedly installed on the bottom of the rotating plate 23. When the rotary lever 23 is rotated, it causes the inclined plate 20 and the rotating circular plate 22 to rotate, thereby allowing the inclined plate 20 to move out of the gap between the U-shaped plate 26 and the supporting side plate 2. At this time, the braking state of the supporting side plate 2 is released, and the supporting side plate 2 can be flipped flat. After flattening, the rotary lever 23 is rotated again, causing it to move above the supporting side plate 2, and causing the rubber block 21 to engage inside the supporting side plate 2, thus braking the supporting side plate 2.

[0034] Two symmetrically arranged threaded holes 28 are provided inside the support side plate 28. The threaded rod 18 passes through the threaded holes 28. An adjusting block 16 is fixedly installed on the top of the threaded rod 18, and a frustum block 19 is fixedly installed on the bottom of the adjusting block 16. After the support side plate 2 is flipped, the adjusting block 16 can be rotated. The adjusting block 16 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the frustum block 19 to move up and down. This allows the device to be placed flat according to the terrain, facilitating subsequent testing and ensuring that the equipment can be placed stably under different ground conditions, thereby improving the accuracy of the test data.

[0035] This application can be used in the field of geological disaster hazards, or in other fields applicable to this application.

[0036] In another embodiment: Reference Figure 1-7 A crack depth detection device for geological disaster hazard points is disclosed. In the field of geological disaster hazard detection, L-shaped plates II 7, I 6, and the fixed slide rail 5 all have slotted holes 13 inside. A fixing screw 12 is threaded through the inside of the slider 14, and the fixing screw 12 engages with the slotted hole 13. One end of the fixing screw 12 abuts against the inner wall of one side of the slotted slide 15. The fixing screw 12 can limit the slider 14 to a suitable height, thereby adjusting the height of the fixed slide rail 5, L-shaped plates II 7 and I 6, increasing the applicability of the device, facilitating the detection process, and enabling the equipment to adapt to the needs of crack detection at different depths and locations.

[0037] This crack depth detection equipment for potential geological disaster sites solves the problems of limited functionality, restricted detection range, unstable support, and inconvenient adjustment of existing detection equipment by combining multiple detection methods, flexible adjustment of detection component positions, and a stable support structure. It can accurately and comprehensively obtain crack depth information of potential geological disaster sites, providing a reliable basis for geological disaster prevention and control.

[0038] The device also includes a microcontroller controller, which is electrically connected to the camera 9, the fill light 10, and the crack depth tester 3.

[0039] The sliding mating surfaces (such as the slider and the strip groove, the sliding sleeve and the fixed slide rail) and threaded mating surfaces (such as the threaded rod and the threaded hole) of this device need to be cleaned of dust and lubricated regularly to ensure the flexibility of component movement and the service life of the equipment.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the crack depth tester 3, camera 9 and supplementary light 10 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
