Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flood prevention equipment, in particular to a rapid plugging device for dam breach. BACKGROUND

[0002] Dam breach is a typical special rescue operation, and the repair time directly relates to the flood control safety of the downstream area. Once the breach occurs, the water flow will rapidly erode the riverbed and dam foundation, causing the mouth width to continuously expand. If it cannot be timely controlled, it may cause a larger range of breach. Therefore, rescue operations must be done in a hurry, and usually require completing the preliminary plugging within a few hours to stop the deterioration of the situation. The time pressure not only comes from the deterioration of hydrological conditions (such as rising water level and increasing flow rate), but also is limited by the extreme weather (such as heavy rain and strong wind) during the flood season, which further compresses the operation window and puts higher requirements on the efficiency of rescue.

[0003] In the process of repairing the breach, large mechanical equipment (such as a shovel truck and a excavator) is a key tool to improve the operation efficiency. The traditional method relies on these devices to complete multiple core links: material transportation and stacking: the shovel truck quickly transports sandbags, stone materials and other erosion prevention materials to the breach area, and stacks them layer by layer to form a temporary cofferdam to slow down the water flow; earthwork backfilling: the excavator is used to excavate the earth and stone materials on both sides of the embankment and directly backfill them to the inside of the breach to gradually narrow the mouth width; structure reinforcement: large equipment can cooperate with the sinking row, sinking ship and other processes to accurately place prefabricated components at the bottom of the breach to form a stable plugging foundation.

[0004] However, the efficiency of such operation is subject to many factors: first, the equipment needs to be opened into the operation area from the surrounding road or temporary road, and the ground in the breach area is often soft and steep due to water erosion, so the equipment has great difficulty in passing, and needs to be repaired or an operation platform needs to be built, which takes a long time; second, the operation radius of large machinery is limited, and it is difficult to operate directly in narrow or deep water areas, and needs to rely on auxiliary facilities (such as floating bridges and trestle roads) to expand the operation range, further prolonging the preparation time; in addition, the operation of the equipment needs to be coordinated with manual work, such as positioning erosion prevention materials and adjusting the stacking angle, which has a high coordination cost.

[0005] Although large equipment can significantly improve the engineering quantity of a single operation, its deployment and operation itself needs time accumulation. For example, it may take tens of minutes for a shovel truck to open from the gathering point to the breach site, and after the equipment is in place, it needs to be debugged and tested before it can enter the formal operation state. In the special rescue scene, this "preparation-operation" cycle may cause time waste, especially when the breach is in the rapid development stage, the lagging response of the equipment may miss the best intervention opportunity. Therefore, how to maximize the efficiency of the equipment within a limited time has become one of the core challenges of the traditional repair mode.

[0006] In summary, the special operation of repairing the dam breach is highly sensitive to time, and although large-scale mechanical equipment can improve operation efficiency, its deployment and operation still need to consider environmental adaptability and coordinated scheduling, which puts higher requirements on rescue organization.

DETAILED DESCRIPTION

[0085] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0086] Please refer to Figures 1-12 The present application provides a technical solution: a rapid plugging device for dam breach, comprising:

[0087] The counterweight base 1 is in isosceles trapezoidal structure, the bottom plate surface is uniformly distributed with pile mounting hole 11, the hole is provided with pile 5 cooperating with anchor system, the front end is symmetrically provided with connector 12;

[0088] The dynamic water blocking system 2 is composed of water blocking plate 21, steel wire rope 22 and intelligent locking assembly 23:

[0089] The lower end of the water-blocking plate 21 is movably connected to the center axis position of the upper surface of the counterweight base 1 through a hinge 211, and the top is fixedly installed with a ceiling point 212;

[0090] The upper end of the steel wire rope 22 is connected to the top center point of the water-blocking plate 21, and the lower end penetrates the curved corner passage 13 opened on the upper surface of the counterweight base 1;

[0091] The intelligent locking assembly 23 is fixed to the mounting boss 14 in the middle of the side wall of the counterweight base 1, and clamps the end of the steel wire rope 22;

[0092] The buoyancy conversion assembly 3 includes inflatable airbags 31 symmetrically embedded on both sides of the counterweight base 1, and has gas release and water injection dual modes;

[0093] The modular docking mechanism 4 is arranged in the sliding groove 213 of the vertical edge of the water-blocking plate 21, and includes a slidable ball hinge connector 41;

[0094] Among them, the anchoring system, the dynamic water-blocking system 2 and the buoyancy conversion assembly 3 are linked through control logic to realize the integrated plugging process of floating positioning, sinking anchoring and self-adaptive water-blocking;

[0095] Specifically, the positioning pile 5 includes:

[0096] The telescopic sleeve 51 is composed of an outer sleeve 511 and an inner sleeve 512:

[0097] The lower end flange of the outer sleeve 511 is fixed to the positioning pile mounting hole 11 at the bottom of the counterweight base 1;

[0098] The inner sleeve 512 is coaxially sleeved in the inner cavity of the outer sleeve 511 and can move axially and telescopically;

[0099] The hydraulic locking cylinder 52 penetrates the pipe wall of the outer sleeve 511 and the inner sleeve 512 radially, and locks the relative position of the two;

[0100] The pile head 53 is connected to the bottom end of the inner sleeve 512 through a quick release interface, and the pile head 53 is a conical soil breaking head or a spiral blade head;

[0101] The positioning pile 5 is a key executive component of the cooperative anchoring system, and its overall structural design takes into account installation adaptability, anchoring reliability and operation flexibility. The positioning pile 5 specifically includes three main components: a telescopic sleeve 51, a hydraulic locking cylinder 52 and a pile head 53. The telescopic sleeve 51 is composed of an outer sleeve 511 and an inner sleeve 512. The lower end of the outer sleeve 511 is fixedly connected to the positioning pile mounting hole 11 at the bottom of the counterweight base 1 through a flange structure, thereby ensuring that the entire positioning pile 5 forms a stable mechanical connection foundation with the counterweight base 1. The inner sleeve 512 is coaxially sleeved in the inner cavity of the outer sleeve 511 and has the ability to move axially, so that the overall length of the positioning pile 5 can be dynamically adjusted according to the actual riverbed geological conditions or water depth, improving the applicability of the device in different breach environments. The hydraulic locking cylinder 52 is arranged radially through the pipe wall of the outer sleeve 511 and the inner sleeve 512. Its function is to reliably lock the relative position between the two. When the inner sleeve 512 is adjusted to the desired extended length, the hydraulic locking cylinder 52 is activated to rigidly fix the outer sleeve 511 and the inner sleeve 512 through internal hydraulic action, preventing axial slipping during subsequent piling or stress process, thereby ensuring the stability and safety of the anchoring process. The pile head 53 is connected to the bottom end of the inner sleeve 512 through a quick-release interface. Its structural form can be selected as a conical soil-breaking head or a spiral blade head. The conical soil-breaking head is suitable for relatively soft or medium-density strata, facilitating rapid penetration of surface silt or sand. The spiral blade head is more suitable for use when the anti-pulling capacity needs to be enhanced or when dealing with hard soil layers. The quick-release interface design facilitates quick replacement of different types of pile heads 53 according to the site conditions, significantly improving the operation efficiency and environmental adaptability of the device.

[0102] Specifically, the cooperative anchoring system further includes a hydraulic piling driving assembly 6 integrated inside the counterweight base 1. The hydraulic piling driving assembly 6 includes:

[0103] A hydraulic impact hammer 61 vertically suspended above the positioning pile 5, with the hammer axis coinciding with the pile axis;

[0104] A pressure sensor 62 embedded in the center of the hammer head bottom surface of the hydraulic impact hammer 61;

[0105] An acoustic range finder 63 installed on the bottom surface of the counterweight base 1, with its probe facing the axis direction of the positioning pile 5;

[0106] The hydraulic pile driving assembly 6 is the core execution unit of the cooperative anchoring system. The structural design realizes the organic combination of precise pile driving and intelligent feedback. Specifically, it includes three key components: a hydraulic impact hammer 61, a pressure sensor 62, and a sonic range finder 63. The hydraulic impact hammer 61 serves as an execution mechanism and is vertically suspended above the positioning pile 5. The hammer head axis is strictly coincident with the pile body axis, ensuring that the impact force is accurately transmitted along the pile body axis, avoiding tilting or deviation of the pile body from the predetermined position due to eccentric impact. The impact hammer is driven by a hydraulic system, converting the pressure energy of hydraulic oil into mechanical impact energy to achieve efficient sinking of the positioning pile 5. The structural design of the hydraulic impact hammer 61 ensures stable cooperation with the positioning pile 5, ensuring the verticality and stability of the pile driving process. The pressure sensor 62 is embedded in the center of the hammer head bottom surface of the hydraulic impact hammer 61, used to monitor the impact force when the hammer head contacts the positioning pile 5. The sensor converts the impact force data into an electrical signal and feeds back to the control system, allowing the operator to accurately monitor the force value changes during pile driving, avoiding damage to the pile body due to excessive impact force or failure to reach the predetermined anchoring depth due to insufficient impact force. The precise monitoring function of the pressure sensor 62 is a key link in realizing intelligent control of the pile driving process, providing real-time basis for pressure regulation of the hydraulic system. The sonic range finder 63 is installed at the bottom of the counterweight base 1. Its probe is directly opposite the axis direction of the positioning pile 5, used to measure the distance between the positioning pile 5 and the riverbed surface in real time. The range finder accurately calculates the sinking depth of the positioning pile 5 by emitting and receiving sound wave signals, providing real-time depth feedback for the pile driving process. The precise measurement function of the sonic range finder 63 allows the operator to accurately determine whether the anchoring depth of the positioning pile 5 meets the design requirements, effectively avoiding the situation of insufficient anchoring due to insufficient depth or resource waste due to excessive depth. The three components work together to form a complete closed-loop control system. The hydraulic impact hammer 61 performs pile driving actions, the pressure sensor 62 monitors the impact force in real time, and the sonic range finder 63 monitors the pile driving depth in real time. The data of the three components are fed back to the control system together, realizing accurate control of the pile driving process. This design not only improves the pile driving efficiency, but also ensures that the positioning pile 5 can be firmly anchored in the riverbed, providing stable and reliable bottom support for the entire sealing structure, which is a key technical link to realize rapid sealing of dam breach.

[0107] The hydraulic pile driving drive assembly 6 in the device is indeed a high-precision, high-cost special equipment, which includes a hydraulic impact hammer 61, a pressure sensor 62 and a sonic range finder 63, and the three parts together constitute a closed-loop intelligent control system, which ensures the accuracy and reliability of the pile driving process. This precision control system is crucial in emergency rescue scenes such as dam breach, because the breach environment is complex and variable, and the anchoring accuracy is extremely high. Any deviation may lead to failure of plugging. However, in the daily repair work of the breach, the environment is relatively stable, the geological conditions are relatively clear, and the requirement for pile driving accuracy can be appropriately relaxed. A simple device can be used to achieve the pile driving function through a simple mechanical structure, without the need for complex sensors and intelligent control systems. This device has the advantages of simple structure, low manufacturing cost and convenient operation, and is especially suitable for use under normal construction conditions, greatly reducing the cost of equipment. Alternatively, the device itself can be relied on to sink by gravity.

[0108] Specifically, the intelligent locking assembly 23 comprises:

[0109] A hollow fixing cylinder 231 is welded to the wall mounting boss 14 on the side wall of the counterweight base 1.

[0110] Two friction clamping plates 232 are suspended in parallel inside the hollow fixing cylinder 231, and a circular clamping channel is formed between them.

[0111] A bidirectional threaded rod 233 horizontally penetrates the threaded holes in the middle of the two friction clamping plates 232, and the screw threads at both ends are opposite in direction.

[0112] A micro motor 234 is fixed to the motor support 235 on the inner wall of the hollow fixing cylinder 231, and its output shaft is coaxially connected to the end of the bidirectional threaded rod 233.

[0113] A guide rod 236 is provided at each of the four corners of the friction clamping plate 232, and the distal end is fixedly installed on the inner wall of the hollow fixing cylinder 231.

[0114] The intelligent locking assembly 23 is a key executive component of the dynamic water blocking system 2, and its structural design realizes intelligent clamping and releasing of the steel wire rope 22, ensures that the water blocking plate 21 can be accurately positioned and controlled according to the needs of the plugging process, and the intelligent locking assembly 23 specifically includes five main components: a hollow fixing cylinder 231, two friction clamping plates 232, a bidirectional threaded rod 233, a micro motor 234 and a guide rod 236. The hollow fixing cylinder 231 is the main frame of the assembly, and the cylinder body is fixed on the mounting boss 14 of the side wall of the counterweight base 1 by welding, providing a stable installation foundation and protective shell for the entire locking mechanism. The fixing method ensures the structural reliability of the locking assembly 23 in a complex water flow environment. The two friction clamping plates 232 are suspended in parallel inside the hollow fixing cylinder 231, forming a circular clamping channel between them. The diameter of the channel is designed to match the outer diameter of the steel wire rope 22, ensuring that the steel wire rope 22 can be uniformly stressed during clamping and preventing the steel wire rope 22 from slipping or being damaged during the clamping process. The surface of the friction clamping plate 232 is usually covered with a material with a high friction coefficient, which enhances the clamping force and ensures that the steel wire rope 22 does not loosen under water flow impact. The bidirectional threaded rod 233 penetrates through the threaded holes in the middle of the two friction clamping plates 232 horizontally, and the screw threads at both ends are in opposite directions. When the bidirectional threaded rod 233 rotates, the two friction clamping plates 232 will move in opposite directions due to the difference in screw thread direction, thereby achieving opening and closing control of the clamping channel. This design allows the clamping and loosening actions to be synchronized and accurately executed. The micro motor 234 is fixed on the motor support 235 of the inner wall of the hollow fixing cylinder 231, and its output shaft is coaxially connected with the end of the bidirectional threaded rod 233. The micro motor 234 serves as a power source, accurately adjusts the rotation of the bidirectional threaded rod 233 by controlling its rotation direction and speed, and then controls the relative position of the friction clamping plate 232, achieving clamping or loosening operation of the steel wire rope 22. The guide rod 236 is respectively arranged at the four corners of the two friction clamping plates 232, and its end is fixedly installed on the inner wall of the hollow fixing cylinder 231. The guide rod 236 ensures that the friction clamping plate 232 remains parallel and stable during movement, preventing the plate body from shifting or shaking, and ensuring the stability and reliability of the clamping process. The five components work together to form a complete intelligent locking system. When the steel wire rope 22 needs to be clamped, the micro motor 234 drives the bidirectional threaded rod 233 to rotate, causing the two friction clamping plates 232 to move inward and clamp the steel wire rope 22. When the steel wire rope 22 needs to be loosened, the micro motor 234 drives the bidirectional threaded rod 233 in the opposite direction, causing the two friction clamping plates 232 to move outward and release the steel wire rope 22. The entire process is accurately controlled by the control system, achieving intelligent positioning and adjustment of the water blocking plate 21, ensuring that the plugging structure can adaptively adjust the water blocking effect according to the water flow conditions, which is a key technical link to realize rapid plugging of dam breach.

[0116] Ball hinge movable seat 42 is embedded in sliding groove 213 of side wall of water stop plate 21 through sliding block 421;

[0117] First movable ball 43 is nested in ball socket of ball hinge movable seat 42;

[0118] Connecting rod 44 is vertically fixed at one end to outer surface of first movable ball 43, rod body penetrates through sealing sleeve 214 at end of sliding groove 213, and the other end is fixed with second movable ball 45;

[0119] Spring clamping unit 46 automatically locks position of ball hinge movable seat 42 in sliding groove 213;

[0120] Specifically, spring clamping unit 46 comprises:

[0121] Compression spring 461 is fixed at bottom end to bottom surface of hidden groove 422 at top of sliding block 421;

[0123] Side wall of sliding groove 213 is provided with arc-shaped positioning groove 215 matched with arc-shaped clamping head 463;

[0124] The modular docking mechanism 4, as a key connecting component of the dynamic water-blocking system 2, is designed to enable rapid, flexible docking and adaptive locking of modules on both sides of the water-blocking plate 21. Specifically, it comprises four main components: a ball-joint movable seat 42, a first movable ball 43, a connecting rod 44, and a spring-loaded locking unit 46. The ball-joint movable seat 42 is embedded in the groove 213 on the side wall of the water-blocking plate 21 via a slider 421, allowing it to slide linearly along the groove 213. This structural design ensures the stable installation and flexible movement of the modular docking mechanism 4 on the side wall of the water-blocking plate 21, providing... The modular expansion of the water-blocking plate 21 provides basic support. The first movable ball 43 is nested in the ball socket of the ball hinge seat 42, forming a ball hinge connection structure. This ball hinge connection allows the water-blocking plate 21 to be adjusted in multiple directions, enabling it to adapt to water flow impacts from different directions, thereby achieving adaptive adjustment of the water-blocking effect. It also facilitates staggered docking of multiple docking units. The ball socket structure design ensures that the first movable ball 43 can rotate freely 360 degrees within the ball hinge seat 42, improving its responsiveness to changes in water flow. One end of the connecting rod 44 is vertically fixed to the first movable ball 43. 3. On the outer surface, the rod body passes through the sealing sleeve 214 at the end of the slide groove 213, and the other end is fixed with the second movable ball 45. The connecting rod 44 serves as the core connecting component of the modular docking mechanism 4, forming a complete water-blocking structure. The sealing sleeve 214 ensures the sealing of the connecting rod 44 at the end of the slide groove 213, preventing water leakage from the connection point and maintaining the complete water-blocking effect of the water-blocking plate 21. The second movable ball 45 is fixed to the other end of the connecting rod 44, providing a connection point for the modular docking of the water-blocking plate on the other side, enabling the water-blocking plate 21 to achieve multi-module combination and expansion. The second movable ball 45 uses clamps to connect the water-blocking plates on both sides. The modules of plate 21 are connected, and the spring locking unit 46 automatically locks the position of the ball joint movable seat 42 in the slide groove 213. Its structure includes a compression spring 461, a locking block 462 and an arc-shaped locking connector 463. When the ball joint movable seat 42 moves to a specific position in the slide groove 213, the arc-shaped locking connector 463 cooperates with the arc-shaped positioning groove 215 on the side wall of the slide groove 213, and the compression spring 461 achieves automatic locking. This locking mechanism enables the water blocking plate 21 to maintain a stable position under the impact of water flow, prevents the module position from shifting due to the impact of water flow, and ensures the reliability and stability of the water blocking structure.

[0126] The inflatable airbags 31 are symmetrically arranged on both sides of the counterweight base 1;

[0127] Gas release assembly 32 includes:

[0128] The deflation channel 321 has an air inlet connected to the inner cavity of the inflatable airbag 31 and an air outlet connected to the air pump 322.

[0129] An electromagnetic control valve 323 is installed on the air release passage 321.

[0130] The water injection system 33 comprises:

[0131] A water injection passage 331 is provided with a water inlet at the bottom of the counterweight base 1 and a water outlet connected to the inner cavity of the inflatable air bag 31.

[0132] A water injection control valve 332 is installed on the water injection passage 331.

[0133] A water pump 333 is connected to the water inlet of the water injection passage 331.

[0134] The gas release assembly 32 and the water injection control valve 332 are linked to execute the conversion of the inflatable air bag 31 into a water-filled counterweight tank.

[0135] Specifically, the buoyancy conversion assembly 3 further comprises:

[0136] Wing bearing frames 34 are symmetrically arranged on both sides of the counterweight base 1 and are formed by welding longitudinal main beams 341 and transverse support beams 342 to form a grid structure.

[0137] The inflatable air bag 31 is embedded in the grid unit of the wing bearing frame 34.

[0138] An air bag positioning structure 35 comprises:

[0139] A hemispherical positioning protrusion 351 is arranged on the inner wall of the wing bearing frame 34.

[0140] A positioning groove 352 is arranged on the outer surface of the air bag and matches the hemispherical positioning protrusion 351.

[0141] The buoyancy conversion assembly 3 is a key functional module of the sealing structure, and its design realizes efficient cooperation of buoyancy adjustment and weight conversion. The assembly not only includes the inflatable air bag 31, the gas release assembly 32 and the water injection system 33, but also particularly integrates the wing bearing frame 34 and the air bag positioning structure 35 to optimize the overall performance and reliability. The wing bearing frame 34 is symmetrically arranged on both sides of the weight base 1 and is formed into a grid structure by welding the longitudinal main beam 341 and the transverse support beam 342. The frame serves as a support carrier of the inflatable air bag 31, and the grid structure provides uniform support points to ensure that the inflatable air bag 31 maintains stable shape during inflation or water injection, avoiding local stress concentration or structural deformation. The welding connection of the longitudinal main beam 341 and the transverse support beam 342 enhances the overall rigidity of the frame, enabling it to effectively withstand water flow impact and internal pressure changes of the air bag, while providing a precise installation and positioning basis for the inflatable air bag 31. The inflatable air bag 31 is embedded in the grid unit of the wing bearing frame 34, and this embedding method forms a close integrated structure of the air bag and the frame. The fixed position of the air bag is accurately controlled by the air bag positioning structure 35, ensuring that the air bag does not shift or fall off during operation, thereby ensuring the stability of buoyancy conversion. The air bag positioning structure 35 includes the hemispherical positioning protrusion 351 arranged on the inner wall of the wing bearing frame 34 and the positioning groove 352 arranged on the outer surface of the air bag. The matching design of the hemispherical positioning protrusion 351 and the positioning groove 352 enables the air bag to be accurately embedded in the specified grid unit of the wing bearing frame 34 and always maintain a stable position during air bag inflation or water injection. This positioning mechanism effectively prevents the air bag from shaking or deviating under water flow impact, improving the accuracy and reliability of buoyancy conversion. The gas release assembly 32 and the water injection system 33 are linked to realize the function conversion of the inflatable air bag 31: the air release channel 321 in the gas release assembly 32 is connected to the inner cavity of the inflatable air bag 31, and the electromagnetic control valve 323 controls gas release; the water inlet of the water injection channel 331 in the water injection system 33 is arranged at the bottom of the weight base 1, and the water injection control valve 332 and the water pump 333 work cooperatively to inject water into the air bag. When floating positioning is needed, the gas release assembly 32 is opened, and the air bag is inflated to float up. When sinking anchoring is needed, the water injection system 33 is started, and the air bag is converted into a weight water tank. The linkage of the gas release assembly 32 and the water injection control valve 332 ensures the synchronization and safety of state switching, avoiding instability or failure of the air bag during conversion. In summary, the cooperative design of the wing bearing frame 34 and the air bag positioning structure 35 provides a stable and reliable installation and positioning basis for the inflatable air bag 31; the linkage mechanism of the gas release assembly 32 and the water injection system 33 realizes automatic control of buoyancy conversion, and the three work together to enable the buoyancy conversion assembly 3 to efficiently complete the whole process of floating positioning, sinking anchoring and weight conversion.

[0142] Specifically, the water blocking plate 21 includes:

[0143] A flexible water-blocking film 216 is coated on the outer surface of the water-blocking plate 21;

[0144] A deformable support skeleton 217 is embedded in the interior of the water-blocking plate 21, and the wing part bears the frame 34 and is attached to the inner side of the flexible water-blocking film 216;

[0145] The deformable support skeleton 217 restricts the deformation range of the flexible water-blocking film 216, and the two cooperatively form an adaptive water-blocking curved surface in response to the water flow pressure;

[0146] Specifically, the flexible water-blocking film 216 is composed of an aramid fiber anti-puncture layer on the water-facing surface;

[0147] The deformable support skeleton 217 is a gas-filled tube skeleton 2171, and the tube body intersection nodes are covered with metal reinforcing sheets 2172;

[0148] The gas inlet of the gas-filled tube skeleton 2171 is connected to the internal gas source distributor 36 in the counterweight base 1 through a hose 37, and the gas source distributor 36 is in communication with the gas pump outlet of the buoyancy conversion assembly 3;

[0149] The water-blocking plate 21 as the core executive component of the dynamic water-blocking system 2 realizes the self-adaptive adjustment of the water-blocking effect through the structural design, which specifically includes two key components of the flexible water-blocking film 216 and the deformable support skeleton 217. The flexible water-blocking film 216 is coated on the outer surface of the water-blocking plate 21 and is the outer layer of protection directly contacted by the water flow. The film is made of high-flexibility and low-permeability polymer materials and has excellent water-blocking performance, which can effectively block the water flow through the water-blocking plate. The flexible water-blocking film 216 includes components such as high-density polyethylene, low-density polyethylene, or polyvinyl chloride, and has a very low permeability coefficient, ensuring that the water-blocking effect reaches more than 99%. The surface of the flexible water-blocking film 216 is also compounded with an aramid fiber anti-puncture layer to enhance its anti-puncture performance and prevent sharp objects in the water flow from damaging the water-blocking effect. The deformable support skeleton 217 is embedded in the interior of the water-blocking plate 21 and works cooperatively with the flexible water-blocking film 216. The skeleton adopts the structure of the inflatable pipe frame 2171, and the pipe body intersection nodes are coated with metal reinforcing sheets 2172 to form an internal framework with elasticity and supporting force. This structure can moderately deform under stress while maintaining the integrity of the overall structure, similar to the wrapping of elastic fibers, so that the skeleton can disperse stress to the entire network when stressed, avoiding local cracking. The wing bearing frame 34 is attached to the inner side of the flexible water-blocking film 216 and is part of the buoyancy conversion assembly 3. It forms a close fit with the inner side of the flexible water-blocking film 216 and provides additional support and stability for the water-blocking plate 21. The grid structure design of the wing bearing frame 34 cooperates with the flexible water-blocking film 216, allowing the water-blocking plate 21 to bear stress uniformly when subjected to water flow pressure. The cooperative action of the deformable support skeleton 217 and the flexible water-blocking film 216 is the core function of the water-blocking plate 21. When the water flow impacts the water-blocking plate 21, the deformable support skeleton 217 restricts the deformation range of the flexible water-blocking film 216 to prevent it from deforming excessively or being damaged. At the same time, both respond to water flow pressure, allowing the water-blocking plate 21 to automatically adjust its shape according to the size and direction of the water flow pressure, forming a self-adaptive water-blocking surface. This self-adaptive feature allows the water-blocking plate 21 to maintain optimal water-blocking effect under different water flow conditions, avoiding the local pressure concentration or water-blocking failure that may occur with traditional rigid water-blocking plates. Through the cooperative work of flexible materials and deformable skeletons, dynamic adjustment of the water-blocking effect is achieved. Compared with traditional rigid water-blocking plates, this flexible design not only improves the water-blocking efficiency but also enhances the adaptability of the water-blocking plate 21 to complex water flow environments. In summary, the cooperative design of the flexible water-blocking film 216 and the deformable support skeleton 217 allows the water-blocking plate 21 to automatically adjust its shape according to the water flow pressure, forming a self-adaptive water-blocking surface, effectively improving the efficiency and reliability of dam breach plugging.

[0150] Working principle: The device realizes the rapid plugging and self-adaptive adjustment of dam breaches by integrating functions such as buoyancy conversion, dynamic water-blocking, intelligent locking, and modular connection. Its working principle is based on the following core logic:

[0151] Buoyancy and counterweight conversion: The device is floated and positioned by inflating the inflatable air bag 31, and after water injection, it is converted into a counterweight water tank to increase the sinking force, and cooperates with the positioning pile 5 to complete the bottom anchoring;

[0152] Dynamic water blocking adjustment: The flexible water blocking membrane 216 cooperates with the deformable support skeleton 217 to form a self-adaptive water blocking surface in response to water flow pressure;

[0153] Intelligent linkage control: Through the hydraulic pile driving assembly 6, the intelligent locking assembly 23 and the modular docking mechanism 4, anchoring, angle adjustment and multi-device cooperation are realized;

[0154] Modular expansion: Through the modular docking mechanism 4, multiple devices are connected in parallel, and the staggered connection adapts to long-distance breaches, while intercepting and throwing repair materials.

[0155] The specific working process is as follows:

[0156] Deployment phase:

[0157] The device is towed by a ship from upstream to the breach location, and relies on the inflatable air bag 31 to provide buoyancy to maintain a floating state;

[0158] Slowly approach the breach through the rope traction device, and adjust the position to the target area.

[0159] Sinking and anchoring phase:

[0160] Start the gas release assembly 32, the electromagnetic control valve 323 is opened, and the gas in the inflatable air bag 31 is released;

[0161] The water injection system 33 is started, and the water pump 333 injects water into the air bag through the water injection channel 331, so that it is converted into a counterweight water tank, increasing the weight of the device;

[0162] The device sinks to the riverbed under the action of gravity, the positioning pile 5 is inserted into the riverbed, and the hydraulic pile driving assembly 6 further tamps the pile body through the hydraulic impact hammer 61, completing anchoring.

[0163] Water blocking structure deployment phase:

[0164] The steel wire rope 22 is released after the ship traction force is removed, and the isosceles trapezoidal structure of the counterweight base 1 guides the water flow to form an arched flow;

[0165] The unmanned aerial vehicle and other high-altitude equipment pull the top hanging point 212 of the water blocking plate 21 to make the water blocking plate 21 flip around the hinge 211;

[0166] The water flow force and the lifting force work together to make the flexible water-blocking film 216 and the support framework 217 deform to form a blocking angle. The intelligent locking assembly 23 drives the bidirectional threaded rod 233 through the micro motor 234 to make the friction clamping plate 232 clamp the steel wire rope 22, thereby fixing the angle of the water-blocking plate 21.

[0167] Multi-device cooperation and breach repair stage:

[0168] For a longer breach, multiple devices are connected through the modular docking mechanism 4. The spherical hinge movable seat 42 moves along the sliding groove 213, and the arc-shaped clamping head 463 of the spring clamping unit 46 is embedded in the arc-shaped positioning groove 215. The second movable ball 45 is quickly locked through the clamping hoop;

[0169] The modular docking mechanism 4 is only used for connection and throwing object interception structure and does not directly block water. The upstream side of the breach is thrown by an unmanned aerial vehicle or a mechanical arm.

[0170] The thrown object is intercepted and fixed by the modular docking mechanism 4, gradually filling the breach, and completing the rapid repair.
