Description

Technical Field

[0001] This invention relates to the field of dam detection equipment technology, specifically to a dam collapse detection device and detection method. Background Technology

[0002] As the core water-retaining structure of water conservancy projects, the safety and stability of dams are directly related to the safety of life and property of people downstream and regional economic development. During long-term operation, dams are susceptible to leakage, cracks, and deformation due to factors such as water erosion, soil seepage, and environmental erosion. If these issues are not detected and addressed in a timely manner, they will gradually develop into collapse accidents, causing catastrophic consequences. Therefore, installing dam collapse detection devices is of great significance for the safety protection of water conservancy projects. However, existing dam detection devices still have some problems in their use, as follows:

[0003] Existing dam collapse detection technologies largely rely on mature detection equipment such as radar and cameras, identifying potential hazards by collecting physical parameters of the dam body. For example, Chinese patent CN115343297A discloses a biomimetic visual cyclic detection device for dam integrity, which uses a self-propelled frame to drive a multi-directional visual detection mechanism and uses an image acquisition head to scan and collect images to detect dam damage. However, it relies too heavily on visual equipment, and its detection accuracy drops significantly in harsh environments such as heavy rain, fog, and nighttime, and it cannot detect potential seepage hazards inside the dam body. Chinese patent CN117191668A discloses a rapid quantitative method for the degree of seepage in earth-rock dams, which uses electromagnetic induction equipment in conjunction with chloride ion concentration monitoring equipment to identify seepage channels by detecting changes in the magnetic field. However, the effective signal is easily attenuated due to interference from cables and natural sources around the dam, and the stability of the electromagnetic sensor is significantly affected by soil moisture and temperature.

[0004] To avoid the drawbacks of sensor dependence, some existing technologies attempt to use mechanical structures for detection, but these have significant shortcomings: First, mechanical structures have limited functionality, only able to detect single hidden dangers in dam surface deformation or internal leakage, unable to pinpoint the location and direction of collapse, making it difficult to comprehensively predict collapse risks; second, the independent design of mechanical structures means that the detection and protection structures lack a linkage mechanism, so even if a hidden danger is detected, it can only be addressed manually through early warning, unable to proactively implement protection measures in the early stages of collapse to slow the accident's progress, resulting in a disconnect between detection and protection, and failing to effectively reduce disaster losses.

[0005] Therefore, we propose a dam collapse detection device and detection method. Summary of the Invention

[0011] In a preferred embodiment, the permeation drive assembly includes a housing with an inner chamber inside. A pressure sensor is disposed on the inner wall of the inner chamber. A limit ring is fixedly disposed on the lower outer side of the housing. A spring is fixedly installed inside the inner chamber. A rod is movably installed through the inner chamber. A drive gear is fixedly installed at the bottom end of the rod. Turbine blades are uniformly fixedly installed in a ring on the upper outer side of the housing.

[0012] In a preferred embodiment, the outer shell is embedded and fixedly installed within a fixed frame. The inner chamber has a rectangular cross-section, and the bottom opening of the inner chamber is smaller than the top opening. The limiting ring is rotatably connected to the fixed frame via a bearing. A pressure plate is provided at the top of the insertion rod, and the spring is located below the pressure plate at the top of the insertion rod and fits against it. The drive gear and the conversion assembly are detachably meshed. The inner chamber is positioned directly opposite the water inlet.

[0013] In a preferred embodiment, the internal conduction assembly includes a drive rod with a limiting protrusion embedded in its outer surface. A connecting collar is movably connected to the top of the drive rod, a trigger block is movably sleeved at the top of the drive rod, and a pull block is movably sleeved at the bottom of the drive rod. The drive rod is movably positioned in the middle of the tube body, and its bottom end is rotatably positioned at the bottom of the vertical groove. Both the upper and lower ends of the drive rod are provided with threaded grooves. The trigger block and the pull block are threadedly connected to the threaded grooves on the drive rod, respectively. The side of the pull block is fixedly connected to the sealing assembly, and the top of the trigger block is in contact with the bottom of the warning module. The trigger block and the pull block are respectively slidably inserted into the first limiting groove and the second limiting groove.

[0014] In a preferred embodiment, the conversion assembly includes a core ring with an inner groove on its inner wall. An upper toothed ring is fixedly mounted on the top end of the core ring, and a lower toothed ring is fixedly mounted on the bottom end of the core ring. The core ring is movably sleeved on the drive rod. The inner groove is located at the position of the limiting protrusion, and the diameter of the upper toothed ring is smaller than the diameter of the lower toothed ring.

[0015] In a preferred embodiment, the sealing assembly includes a sealing plate, a pad is movably mounted on the bottom end of the sealing plate, a pull rope is fixedly mounted on the bottom end of the pad, the sealing plate is installed at an angle downwards on the water-facing side of the dam assembly, the pad is hinged to one rotating end of the bottom end of the sealing plate, and a return spring is embedded in the rotating connection.

[0016] A detection method for a dam collapse detection device, the specific detection method is as follows:

[0017] S1. Perform pre-setting of the structure and preliminary testing of the detection device;

[0018] S2. When a small-scale leak or collapse occurs, water will seep through the inlet hole into the pipe body. The seeping water will impact the turbine blades and push the insert rod to move, thereby compressing the spring. The turbine blades are driven to rotate, which in turn drives the drive gear to rotate. The insert rod will push the drive gear to mesh with the lower gear ring, which in turn drives the drive gear ring to rotate. This will drive the core ring to drive the drive rod to rotate, which will cause the pull block at the bottom to move upward, thereby pulling the pull rope and causing the sealing plate to rotate and fit against the side of the dam wall to block the river water flow and prevent it from entering the dam components.

[0019] S3. Personnel can determine whether an internal collapse or leak has occurred by checking whether the sealing plate is rotated downwards to fit properly.

[0020] S4. When a small-scale leak or collapse occurs, water will also seep through the inlet hole into the pipe body. At this time, the drive gear will rotate and push the drive gear to mesh with the upper gear ring, which will cause the internal transmission component to rotate as a whole, so that the upper trigger block moves to touch the bottom of the warning module to trigger the alarm, thereby reminding personnel to check.

[0021] The present invention has the following beneficial effects:

[0022] 1. The dam collapse detection device and method involves evenly inserting multiple detection sleeve assemblies inside the dam body components. An internal conduction component is movably installed inside each detection sleeve assembly. When localized seepage occurs within the dam body components, the leaking water enters the detection sleeve assembly, triggering the rotation of the seepage drive component. This, in turn, moves the lower pulling block, pulling and rotating the sealing component to fit against the water-facing side of the dam body component. This prevents water from the internal river channel from continuously seeping into the dam body component through cracks in the area where collapse is imminent. This allows for initial automatic detection and protection based on the seeping water, preventing continuous seepage from ultimately causing collapse. This demonstrates the automatic protection effect of the detection device.

[0023] 2. The dam collapse detection device and method utilize multiple permeation drive components evenly fitted onto the inner transmission component, with each component positioned directly opposite the water inlet on the pipe. When seepage and collapse occur within the dam component, the water flow impacts the permeation drive component, causing it to rotate. This rotation, in turn, drives the conversion component to rotate. When the seepage volume is small, the impact of the water flow only causes the permeation drive component to rotate in one direction, resulting in the structure on the bottom inner transmission component moving upwards. This pulls the sealing component to rotate and fit against the water-facing side of the dam component, achieving initial river flow isolation. However, when the seepage volume is large, it impacts the internal expansion and contraction of the permeation drive component, causing the conversion component to rotate in the opposite direction. This causes the structure on the inner transmission component to touch the fixed frame, triggering an alarm and ensuring rapid and effective detection. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The dam collapse detection device and detection method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-3 A dam collapse detection device includes a dam body component 1, a detection sleeve component 2 inserted into the dam body component 1, a fixed frame 3 fixedly installed inside the dam body component 1, a seepage drive component 4 fixedly installed on the fixed frame 3, an internal conduction component 5 installed inside the detection sleeve component 2, a conversion component 6 movably sleeved on the internal conduction component 5, a sealing component 7 fixedly connected to the internal conduction component 5, and an early warning module 8 fixedly installed at the top of the dam body component 1.

[0036] Compared with existing technologies, this application, by uniformly inserting multiple detection sleeve assemblies 2 inside the dam body component 1, and movably installing an internal conduction assembly 5 inside the detection sleeve assembly 2, allows water to seep into the detection sleeve assembly 2 when local leakage occurs in the dam body component 1. This triggers the rotation of the seepage drive assembly 4, which in turn moves the lower pulling block 55, pulling and rotating the sealing assembly 7 to fit the water-facing side of the dam body component 1. This prevents water from the internal river channel from continuously flowing into the dam body component 1 through cracks in the area where collapse is imminent. This allows for initial automatic detection and protection based on the seeping water, preventing the dam body component 1 from collapsing due to continuous seepage. This demonstrates the automatic protection effect of the detection device. Furthermore, by uniformly inserting multiple... The permeation drive component 4 is positioned directly opposite the inlet hole 24 on the pipe body 21. When seepage and collapse occur inside the dam body component 1, the water flow will impact the permeation drive component 4 to rotate. The rotation of the permeation drive component 4 will then drive the conversion component 6 to rotate. When the seepage volume is small, the impact of the water flow will only drive the permeation drive component 4 to drive the conversion component 6 to rotate in one direction, thereby causing the structure on the inner conduction component 5 at the bottom to move upward, pulling the sealing component 7 to rotate and fit against the water-facing surface on the outside of the dam body component 1 to achieve initial river flow isolation. When the seepage volume is large, it will impact the internal expansion and contraction of the permeation drive component 4, thereby causing the conversion component 6 to rotate in the opposite direction. This will cause the structure on the inner conduction component 5 to touch the fixed frame 3, thereby triggering the fixed frame 3 to realize an alarm, thus achieving rapid and effective detection.

[0037] Please see Figure 1-2 A dam collapse detection device includes a dam body component 1, which includes a dam wall 11. The dam wall 11 is divided into a water-facing side and a water-repellent side. An external groove 12 is provided on the water-facing side. A vertical groove 13 is provided inside the dam wall 11. A drainage groove 14 is provided at the bottom end of the vertical groove 13.

[0038] In this embodiment, it should be noted that the outer groove 12 and the vertical groove 13 are positioned in a one-to-one correspondence. The vertical groove 13 is evenly distributed laterally inside the dam wall 11. The drainage groove 14 is opened laterally towards the back water side of the dam wall 11. The detection sleeve assembly 2 is inserted and fixedly installed in the vertical groove 13. In this way, when there is a possibility of leakage or collapse of the dam body, water seepage will occur. The seeping water will flow into the interior of the dam wall 11. In particular, the water flow inside the river channel is more likely to seep in under the action of huge water flow pressure. The seeping water will pass through the detection sleeve assembly 2 and enter it. This will drive the internal structure to operate, so that the sealing assembly 7 can seal the water-facing side of the dam wall 11 in time, preventing too much water from seeping into it, thereby reducing the speed of dam collapse.

[0039] Please see Figure 1-3 A dam collapse detection device includes a detection sleeve assembly 2, which includes a tube body 21. A first limiting straight groove 22 is symmetrically fixedly installed at the top of the inner end of the tube body 21, and a second limiting straight groove 23 is symmetrically fixedly installed at the bottom of the inner end of the tube body 21. Water inlet holes 24 are evenly opened on the tube body 21.

[0040] In this embodiment, it should be noted that the pipe body 21 is fixedly inserted into the vertical groove 13, and the second limiting straight groove 23 extends out of the bottom end of the pipe body 21 and is fixedly installed in the vertical groove 13. The upper and lower ends of the inner conduction component 5 are respectively slidably limited inside the first limiting straight groove 22 and the second limiting straight groove 23. In this way, when the collapse of the dam wall 11 occurs, the infiltrated water will pass through the water inlet hole 24 and impact the rotation of the infiltration drive component 4, thereby driving the conversion component 6 to rotate. This can drive the inner conduction component 5. When the infiltrated water pressure is small, it will drive the lower structure of the inner conduction component 5 to move upward, thereby driving the sealing component 7 to seal the water-facing side of the dam wall 11 to prevent excessive infiltration and collapse that could cause the dam to be washed away. When the infiltrated water pressure is large, it will drive the upper structure of the inner conduction component 5 to move upward, thereby triggering the fixed frame 3 to issue an early warning, so as to realize the detection and early warning function of the detection device.

[0041] Please see Figure 6-8 A dam collapse detection device includes a permeation drive assembly 4, which includes an outer shell 41. An inner chamber 42 is opened inside the outer shell 41. A pressure sensor is installed on the inner wall of the inner chamber 42. A limit ring 43 is fixedly installed on the lower outer side of the outer shell 41. A spring 44 is fixedly installed inside the inner chamber 42. A rod 45 is movably installed through the inner chamber 42. A drive gear 46 is fixedly installed at the bottom end of the rod 45. Turbine blades 47 are evenly fixedly installed in a ring on the upper outer side of the outer shell 41.

[0042] In this embodiment, it should be noted that the outer shell 41 is embedded and fixedly installed within the fixed frame 3. The inner chamber 42 has a rectangular cross-section, and the bottom opening of the inner chamber 42 is smaller than the top opening. The limiting ring 43 is rotatably connected to the fixed frame 3 via a bearing. A pressure plate is provided at the top of the insertion rod 45, and the spring 44 is located below the pressure plate at the top of the insertion rod 45 and fits against it. The drive gear 46 and the conversion component 6 are detachably meshed. The inner chamber 42 is positioned directly opposite the water inlet 24. In the event of a leak, water pressure will enter the pipe 21 through the water inlet 24. Some of the water will impact the turbine blades 47, causing the outer shell 41 to rotate. At the same time, the impact force of the water entering will synchronously compress the spring 44, thereby causing the drive gear 46 to reach a position where it can mesh with the conversion component 6. This will drive the drive gear 46 to drive the conversion component 6 to rotate, and the conversion component 6 will drive the inner transmission component 5 to rotate to provide auxiliary protection for the corresponding structure, ensuring the effectiveness of the detection structure.

[0043] Please see Figure 1-5 A dam collapse detection device includes an inner transmission component 5, which includes a drive rod 51. A limiting protrusion 52 is embedded in the outer side of the drive rod 51. A connecting collar 53 is movably connected above the top of the drive rod 51. A trigger block 54 is movably sleeved at the top of the drive rod 51. A pulling block 55 is movably sleeved at the bottom of the drive rod 51.

[0044] In this embodiment, it should be noted that the drive rod 51 is movably positioned in the middle of the pipe body 21, and its bottom end is rotatably positioned in the bottom of the vertical groove 13. Both the upper and lower ends of the drive rod 51 are provided with threaded grooves. The trigger block 54 and the pull block 55 are threadedly connected to the threaded grooves on the drive rod 51, respectively. The side of the pull block 55 is fixedly connected to the sealing component 7, and the top end of the trigger block 54 is abutting against the bottom end of the early warning module 8. The trigger block 54 and the pull block 55 are respectively limited and movably inserted into the first limiting straight groove 22 and the second limiting straight groove 23 and slidably positioned. In this way, when the permeation drive component 4 is driven to rotate by the water flow, and then the drive rod 51 is driven to rotate through the conversion component 6, the direction of rotation will determine whether to drive the trigger block 54 or the pull block 55, and thus automatically determine the severity of the possible collapse. In a more serious case, the early warning module 8 will be triggered to issue an alarm, while in a less serious case, the sealing component 7 will be triggered to attach downward to the dam component 1 to block the water flow in the river channel and prevent it from permeating into the dam component 1 and aggravating the collapse.

[0045] Please see Figure 1-6 A dam collapse detection device includes a conversion component 6, which includes a core ring 61. An inner groove 62 is provided on the inner wall of the core ring 61. An upper toothed ring 63 is fixedly installed at the top of the core ring 61, and a lower toothed ring 64 is fixedly installed at the bottom of the core ring 61.

[0046] In this embodiment, it should be noted that the core ring 61 is movably sleeved on the drive rod 51, the inner groove 62 is located at the position of the limiting protrusion 52, and the diameter of the upper toothed ring 63 is smaller than the diameter of the lower toothed ring 64. In this way, when the permeation drive assembly 4 is driven to rotate by the water flow, it will be compressed. According to the amount of compression, the upper toothed ring 63 or the lower toothed ring 64 will be driven to rotate accordingly, thereby realizing the forward or reverse rotation of the entire conversion assembly 6. This allows for automatic differentiation of whether the current permeation situation is severe, demonstrating the automatic detection effect of the detection device.

[0047] Please see Figure 2-9 A dam collapse detection device includes a sealing component 7, which includes a sealing plate 71. A pad 72 is movably installed at the bottom end of the sealing plate 71, and a pull rope 73 is fixedly installed at the bottom end of the pad 72.

[0048] In this embodiment, it should be noted that the sealing plate 71 is installed tilted downwards on the water-facing side of the dam assembly 1. The pad 72 is hinged to the bottom rotating end of the sealing plate 71, and a reset coil spring is embedded in the rotating connection. In this way, when water seeps into the collapsed position, it will enter the inside of the pipe 21, thereby driving the trigger block 54 to move upwards. This will cause the pull rope 73 to pull the pad 72 and simultaneously drive the sealing plate 71 to fit and cover the dam assembly 1, thereby preventing excessive leakage of water from the river into the dam assembly 1 and increasing the collapse process, thus ensuring the automatic protection effect of the detection device.

[0049] A detection method for a dam collapse detection device, the specific detection method is as follows:

[0050] S1. Perform pre-setting of the structure and preliminary testing of the detection device;

[0051] S2. When a small-scale leak or collapse occurs, water will seep through the inlet hole 24 into the pipe body 21. The seeping water will impact the turbine blades 47 and push the insert rod 45 to move, thereby compressing the spring 44. The turbine blades 47 are driven to rotate, which drives the drive gear 46 to rotate. The insert rod 45 will push the drive gear 46 to mesh with the lower gear ring 64, which in turn drives the drive gear 46 to drive the lower gear ring 64 to rotate, which in turn drives the core ring 61 to drive the drive rod 51 to rotate. This will cause the pull block 55 set at the bottom to move upward, which will pull the pull rope 73 to drive the sealing plate 71 to rotate and fit against the side of the dam wall 11 to block the river water flow and prevent it from entering the dam body component 1.

[0052] S3. Personnel can determine whether internal collapse and leakage have occurred by checking whether the sealing plate 71 is rotated downwards and fits properly.

[0053] S4. When a small-scale leak or collapse occurs, water will also seep through the inlet hole 24 into the pipe body 21. At this time, the drive gear 46 will rotate and engage with the upper gear ring 63, which will cause the inner transmission component 5 to rotate as a whole, so that the upper trigger block 54 moves to touch the bottom of the warning module 8 to trigger the alarm, thereby reminding personnel to check.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The dam collapse detection device according to claim 1, characterized in that: The conversion component (6) includes a core ring (61), an inner groove (62) is provided on the inner wall of the core ring (61), an upper toothed ring (63) is fixedly installed at the top of the core ring (61), a lower toothed ring (64) is fixedly installed at the bottom of the core ring (61), the core ring (61) is movably sleeved on the drive rod (51), the inner groove (62) is located at the position of the limiting protrusion (52), and the diameter of the upper toothed ring (63) is smaller than the diameter of the lower toothed ring (64).

9. The dam collapse detection device according to claim 1, characterized in that: The sealing assembly (7) includes a sealing plate (71), a pad (72) is movably installed at the bottom end of the sealing plate (71), a pull rope (73) is fixedly installed at the bottom end of the pad (72), the sealing plate (71) is installed at an angle downward on the water-facing side of the dam assembly (1), the pad (72) is hinged to the rotating end of the bottom end of the sealing plate (71), and a return coil spring is embedded in the rotating connection.

10. The detection method of the dam collapse detection device according to any one of claims 1-9, characterized in that, The specific testing methods are as follows: S1. Perform pre-setting of the structure and preliminary testing of the detection device; S2. When a small-scale leak or collapse occurs, water will seep through the inlet hole (24) into the pipe body (21). The seeping water will impact the turbine blades (47) and push the insert rod (45) to move, thereby compressing the spring (44). The turbine blades (47) are driven to rotate, which drives the drive gear (46) to rotate. The insert rod (45) will push the drive gear (46) to mesh with the lower gear ring (64), which in turn drives the drive gear (46) to rotate the lower gear ring (64), which in turn drives the core ring (61) to drive the drive rod (51) to rotate. This will cause the pull block (55) set at the bottom to move upward, which in turn pulls the pull rope (73) to drive the sealing plate (71) to rotate and fit against the side of the dam wall (11) to block the river water flow and prevent it from entering the dam body component (1). S3. Personnel can determine whether internal collapse and leakage have occurred by checking whether the sealing plate (71) is rotated downwards and fits properly. S4. When a small-scale leak or collapse occurs, the water will also seep through the inlet hole (24) into the pipe body (21). At this time, the drive gear (46) will rotate and push the drive gear (46) to mesh with the upper gear ring (63), which will drive the inner transmission component (5) to flip as a whole, so that the upper trigger block (54) moves to touch the bottom of the warning module (8) to trigger the alarm, thereby reminding personnel to check.
