Description

Technical Field

[0001] This invention relates to the field of levee hazard detection technology, specifically to a levee hazard detection device that uses visual penetration and quantitative precision detection. Background Technology

[0002] As the core infrastructure of flood control engineering systems, the structural integrity of dikes is directly related to the flood control safety of the basin. However, during long-term operation, dikes are prone to hidden dangers such as cracks and voids due to factors such as changes in geological conditions, hydraulic effects, and construction defects. If these hidden dangers are not accurately identified and addressed, they may lead to major disasters such as dike breaches.

[0003] Currently, the detection of potential hazards in dikes mainly relies on geophysical exploration technologies such as ground-penetrating radar and high-density electrical resistivity tomography.

[0004] While such technologies can achieve rapid scanning over a wide area and delineate suspected hazard zones based on differences in the physical parameters of the medium, they have significant limitations: First, the detection results are primarily qualitative, making it difficult to accurately quantify the size, shape, and type of the hazard; second, they are prone to misinterpretation due to the complex geological conditions of the dike (such as uneven mud content and interlayer interference), leading to inaccurate hazard location. To verify suspected geophysical exploration areas, traditional methods often employ core drilling or excavation. The former has a limited sampling range and easily damages the structural integrity of the dike, while the latter is destructive, costly, inefficient, and unable to provide real-time, intuitive observation. Existing borehole endoscopes, while providing visual images, can only achieve visual recognition and lack synergistic analysis with mechanical parameters, making it difficult to comprehensively assess the stability and severity of the hazard. Therefore, there is an urgent need for a detection device that combines minimally invasiveness, quantification, and synergistic verification capabilities, particularly a precise, synergistic, and quantitative detection device for dike hazards. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-10 The present invention provides a technical solution: A visual-based, integrated, quantitative, and precise detection device for potential dike hazards, as shown in the instruction manual. Figure 1 As shown, it includes: The main body of the frame 1 is equipped with a sliding rail 2 and a fixing component at the bottom.

[0019] The power penetration assembly includes a loading platform 3, a hammering mechanism, a drill rod 4, and a connecting mechanism. The loading platform 3 is connected to the moving slide rail 2 and is equipped with a comprehensive control console. The comprehensive control console is used to control the operation of the rotating motor 7 and the hydraulic jack 13. The drill rod 4 is connected to the bottom of the loading platform 3. The hammering mechanism is used to hammer the drill rod 4, and the connecting mechanism is used to connect different drill rods 4 to each other.

[0020] The drill pipe 4 lifting assembly is located inside the movable slide rail 2. The drill pipe 4 lifting assembly is used to drive the loading platform 3 to move along the movable slide rail 2, thereby lifting the drill pipe 4.

[0021] The drive assembly is used to drive the hammering mechanism and the drill pipe 4 lifting assembly to work.

[0022] The fastening assembly includes an energy harvesting mechanism and a reinforcement mechanism. The energy harvesting mechanism is used to convert the vibration of the frame body 1 into air pressure for storage, and the reinforcement mechanism is used to reinforce the fastening assembly using the air pressure stored in the energy harvesting mechanism.

[0023] The image acquisition component includes a retractable mechanism and a camera mechanism. The retractable mechanism is used to adjust the height of the camera mechanism, and the camera mechanism is used to acquire images.

[0024] The fixing component includes a balance support leg 5 and a side support leg 6. The balance support leg 5 is located at the bottom of the frame body 1, and the side support leg 6 is connected to the side wall of the frame body 1. In this embodiment, the fixing component is also equipped with a level to detect the horizontal state of the device and ensure the accuracy and safety during operation.

[0025] The hammering mechanism includes a rotary motor 7, a lifting head 8, a falling hammer 9, a limiting shaft 10, and a force transmission head 11. The rotary motor 7 drives the lifting head 8 to rotate, which is connected to the falling hammer 9. The lifting head 8 drives the falling hammer 9 to move along the limiting shaft 10. The limiting shaft 10 is coaxially connected to the force transmission head 11, which is connected to a drill rod 4. The connecting mechanism includes a connecting sleeve 401, which connects adjacent drill rods 4. A cone head 12 is connected to the bottom of the drill rod 4. The connecting sleeve 401 has an internal thread, and the ends of adjacent drill rods 4 have external threads that match the internal thread. The threaded connection achieves a stable connection between the drill rods 4, and facilitates the disassembly and replacement of drill rods 4 of different lengths or types to meet diverse detection needs. The cone head 12 is conical, and its surface is specially treated to have high hardness and wear resistance, which can effectively reduce resistance during penetration and smoothly enter the interior of the dike, providing accurate initial data for subsequent detection work.

[0026] The drill rod 4 lifting assembly includes a hydraulic jack 13 and a top support 14. The hydraulic jack 13 drives the top support 14 to move. When the top support 14 moves, it drives the loading platform 3 to move along the direction of the sliding rail 2, thereby realizing the lifting operation of the drill rod 4. The hydraulic jack 13 has stable power output characteristics and can accurately control the movement speed and lifting force of the top support 14 according to actual needs, ensuring that the drill rod 4 remains stable during the lifting process and avoiding interference with the detection work due to unstable lifting action. The bottom of the top support 14 and the loading platform 3 are not connected.

[0027] The drive assembly includes a generator 15 and a hydraulic press 16. The generator 15 supplies power to the hydraulic press 16, which is connected to the rotary motor 7 and the hydraulic jack 13 via pipelines. The hydraulic press 16 and the rotary motor 7 are connected by a hose (not shown in the accompanying drawings). The hydraulic press 16 provides power to the rotary motor 7 and the hydraulic jack 13. The hydraulic press 16 has efficient and stable power conversion capabilities, converting the electrical energy provided by the generator 15 into powerful hydraulic power, ensuring that the rotary motor 7 and the hydraulic jack 13 receive sufficient and stable power support. The hydraulic press 16 can precisely adjust the output hydraulic pressure and flow rate, so that the hammering force of the rotary motor 7 and the lifting force of the hydraulic jack 13 can be precisely controlled, thereby ensuring that the entire detection device can operate stably in different working scenarios.

[0028] The energy harvesting mechanism includes a connecting rod 17, a limiting ring 18, a linkage rod 19, a piston block 20, a cylinder 21, and an air tank 22. The connecting rod 17 is fixedly connected to the main body 1 of the frame and inserted into the balance support leg 5. One end of the connecting rod 17 is connected to the limiting ring 18. Several cylinders 21 are arranged around the limiting ring 18, and each cylinder 21 is movably connected to a piston block 20. The piston block 20 is connected to the inner wall of the balance support leg 5 through the linkage rod 19. The connecting rod 17 swings with the vibration of the main body 1, thereby driving the piston block 20 in the cylinder 21 to reciprocate. The movement of the piston block 20 in the cylinder 21 changes the air pressure in the cylinder 21, converting the mechanical energy generated by the vibration of the main body 1 into air pressure energy, which is stored in the air tank 22.

[0029] The reinforcement mechanism includes a one-way air inlet valve 23, a hydraulic cylinder 24, a pressure relief switch 25, an oil circuit piston 26, a pressure push rod 27, and a fastening block 28. The air tank 22 is connected to the hydraulic cylinder 24 through the one-way air inlet valve 23. The hydraulic cylinder 24 is equipped with an oil circuit piston 26. The pressure relief switch 25 is connected to the hydraulic cylinder 24. The pressure relief switch 25 is a push-to-open valve. By pressing the pressure relief switch 25, the air inside the hydraulic cylinder 24 is released, thereby causing the oil circuit piston 26 to reset. When the air pressure pushes the oil circuit piston 26 to move along the hydraulic cylinder 24, the hydraulic oil in the hydraulic cylinder 24 will flow into the pressure push rod 27. The pressure push rod 27 is arranged around the limit ring 18, and the pressure push rod 27 is connected to the fastening block 28.

[0030] The winding and unwinding mechanism includes a cable reel 29, and the camera mechanism includes a camera 30. The cable reel 29 is mounted on the main frame 1 and is used to drive the camera 30 to move up and down. Both the cable reel 29 and the camera 30 are existing technologies. The cable reel 29 is used to achieve smooth lifting and lowering of the camera 30, thereby ensuring the clarity and stability of the images captured by the camera 30. In this embodiment, when used in actual use, the cable reel 29 needs to be equipped with a length positioning device to accurately control the lifting height of the camera 30 and meet the requirements for image acquisition position when detecting hazard in dikes at different depths.

[0031] Working principle: (1) When using the device, move it to a location on the dike where there is a suspected hidden danger, adjust the balance support leg 5, and use a level to make the main body 1 of the frame balanced. Then fix the balance support leg 5 with bolts. (2) Connect the hydraulic press 16 and the generator 15. After starting the generator 15, open the external frame switch door and start the integrated control console. Control the hydraulic jack 13 to lift the base of the loading platform 3 to the set height through the integrated control console. (3) Connect one end of the first drill rod 4 to the cone head 12 and the other end to the force transmission head 11. Then, make the cone head 12 at one end of the bottom drill rod 4 contact the ground, and connect the other end to the force transmission head 11 and the loading platform 3 by adjusting the height of the jack. (4) Start the rotating motor 7, and at the same time the hydraulic jack 13 quickly falls to the starting position. The integrated control console automatically records the number of hammer blows and the penetration depth. When the base of the loading platform 3 is 0.1 m away from the jack support 14, the rotating motor 7 automatically stops. (5) Start the hydraulic jack 13, lift the base of the loading platform 3, remove the force transmission head 11, and use the connecting sleeve 401 to connect the second drill rod 4 to the first drill rod 4. Connect the other end of the second drill rod 4 to the force transmission head 11, and repeat the above steps (4). (6) When the penetration depth exceeds the hazard location by 1.0 m, no more drill rods 4 are added, the penetration is stopped, the force transmission head 11 is fixed with the force transmission head 11 fastening plate, the hydraulic jack 13 is started, the loading platform 3 base is lifted, and the drill rods 4 are pulled out. The drill rods 4 are disassembled and pulled out one by one. (7) After the drill rod 4 is pulled out, rotate the main body 1 of the stand and adjust its extension length so that the camera 30 is aligned with the center of the borehole. Rotate the reel 29 so that the camera 30 falls into the bottom of the borehole. Start the recording and depth recording functions of the camera 30. Use the reel 29 to slowly lift the camera 30. The camera 30 records 360° of the borehole wall and captures images of potential hazards. (8) The bearing capacity of the foundation soil is determined by the number of hammer blows, and the type, location and size of the hidden danger are quantitatively assessed by video recording by camera 30 and image capture of hidden danger features; During steps (4) and (5), the main body 1 of the support frame will vibrate during the penetration and lifting of the drill rod 4. The cylinder of the energy capture mechanism will swing with the vibration of the main body 1 of the support frame, driving the piston block 20 in the cylinder 21 to reciprocate, converting the mechanical energy generated by the vibration of the main body 1 of the support frame into air pressure energy, and storing it in the air tank 22. The air pressure in the air tank 22 enters the hydraulic cylinder 24 through the one-way air inlet valve 23, pushing the oil circuit piston 26 to move along the hydraulic cylinder 24. The hydraulic oil in the hydraulic cylinder 24 flows into the pressure push rod 27. The pressure push rod 27 pushes the fastening block 28 to move towards the balance support leg 5 and applies pressure, enhancing the stability of the contact between the balance support leg 5 and the ground, and between the balance support leg 5 and the main body 1 of the support frame, preventing the device from shifting or shaking due to vibration.
