Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a dam breach repair system. Background Technology

[0002] A dam breach refers to the phenomenon where, due to various reasons such as flood impact, dam quality problems, or piping, the dam structure is damaged and can no longer hold back floodwaters, causing a large amount of water to gush out from the breach. After a dam breach, the floodwaters lose the restraint of the dam and overflow uncontrollably, inundating surrounding land, houses, farmland, etc., causing serious damage and threats to people's lives and property, infrastructure, and the ecological environment. It is a relatively serious natural disaster or water conservancy project accident.

[0003] After a dam breach, heavy materials such as sandbags, stones, and concrete blocks are typically used to quickly seal the breach, initially blocking both ends and gradually closing it towards the center. Excavators, bulldozers, and helicopters (for airdropping materials) are deployed to expedite the sealing process. However, during the sealing process, heavy materials like sandbags, stones, and concrete blocks, due to their insufficient weight, are easily washed away when placed at the breach, significantly reducing the efficiency of dam repair. Utility Model Content

[0004] In view of this, the present invention provides a dam breach repair system, which, by using fixing components, can effectively prevent flood control materials from being washed away and improve the efficiency of dam breach repair.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The dam breach repair system provided in this embodiment of the utility model includes:

[0050] The fixing component includes: a blocking structure 10 and a counterweight 20; the blocking structure 10 is made of woven metal mesh, which can be woven into a mesh or cage shape, etc. The first side of the blocking structure 10 is facing the direction of water inflow at the breach of the dam, and is used to block the loss of flood control materials so that the flood control materials can accumulate; the counterweight 20 is set at the bottom of the blocking structure 10, so that after the fixing component is thrown into the water, it can stand at the breach point by the weight of the bottom counterweight 20 and the blocking structure 10. The metal mesh has a certain degree of hardness, which helps to extend the service life of the fixing component;

[0051] The material conveying assembly 40 includes: a storage mechanism 41 and a conveying mechanism 42. The storage mechanism 41 is used to store flood control materials, including but not limited to sandbags, soil bags, stones or concrete blocks.

[0052] The receiving end of the conveying mechanism 42 is located at the discharge port of the storage mechanism, and the discharge end of the conveying mechanism 42 is located between the breach of the dam and the first side of the blocking structure 10.

[0053] In a specific application scenario, when a dam breaches, a fixing device is first placed at the breach. The device, under its own weight, secures itself to the breach opening. Then, the conveying mechanism 42 of the material conveying assembly 40 conveys flood control material between the breach opening and the first side of the blocking structure 10. The flood control material begins to sink under gravity, and the fixing device acts as a barrier, preventing it from flowing away with the water flow and accumulating. This allows the flood control material to accumulate at the breach opening, preventing it from widening and quickly sealing the breach, thus repairing the dam. Preferably, in one embodiment, as... Figures 1a-2c As shown, the blocking structure 10 is an isosceles trapezoidal frame that uses the side of the frame to block the impact of water entering through the breach, and the side and the bottom of the blocking structure 10 are set at an acute angle.

[0054] In one embodiment, the first side of the isosceles trapezoidal frame is positioned facing the water inlet of the dam breach to prevent the loss of flood control materials, and the first side of the isosceles trapezoidal frame and the bottom surface of the isosceles trapezoidal frame are set at an acute angle.

[0055] In the above technical solution, the isosceles trapezoidal frame is subjected to uniform force, and the counterweight 20 at the bottom prevents the fixing component from being knocked over by the water flow. It can better fix the flood control materials transported by the conveying mechanism 42 to the breach. At the same time, the first side of the isosceles trapezoidal frame blocks the impact of the water flow, which further helps to quickly block the breach.

[0056] Optimize the above technical solutions, such as Figure 1b and Figure 1c As shown, there are multiple counterweights 20, with two of the counterweights 20 respectively located on the bottom two sides of the isosceles trapezoidal frame. This arrangement ensures that the gravity on both sides of the fastener is the same, which helps the fastener maintain stability during the impact of water flow. Preferably, the two counterweights 20 have the same weight.

[0057] In another embodiment, such as Figures 2a-2c As shown, the blocking structure 10 is a right-angled trapezoidal frame;

[0058] The first side of the right-angled trapezoidal frame is designed to face the direction of water inflow at the breach of the dam, in order to prevent the loss of flood control materials, and the first side of the right-angled trapezoidal frame and the bottom surface of the right-angled trapezoidal frame are set at an acute angle.

[0059] In the above technical solution, the first side of the right-angled trapezoidal frame blocks the frontal impact of the water flow, effectively preventing the right-angled trapezoidal frame from tipping over. The second side of the right-angled trapezoidal frame supports the first side. The second side and the first side are arranged symmetrically, and the second side and the bottom are set at right angles.

[0060] Optimize the above technical solutions, such as Figure 2b and Figure 2c As shown, there are multiple counterweights 20, and two of the counterweights 20 have different weights. The heavier counterweight 20 is located at the bottom of the right-angled trapezoidal frame facing the water inlet of the dam breach, while the lighter counterweight 20 is located at the bottom of the right-angled trapezoidal frame away from the water inlet of the dam breach.

[0061] In the above technical solution, the heavier counterweight 20 can avoid the frontal impact of the water flow, effectively prevent the fixing component from tilting, and allow the flood control material to quickly block the breach.

[0062] In yet another embodiment, such as Figures 3a-3c As shown, the blocking structure 10 is a rectangular frame;

[0063] The first side of the rectangular frame is oriented towards the direction of water inflow at the breach of the dam, and is used to prevent the loss of flood control materials. The first side of the rectangular frame has a larger area than the side of the adjacent rectangular frame.

[0064] In the aforementioned technical solution, the large area of ​​the first side of the rectangular frame maximizes the blocking of the frontal impact of the water flow, which is conducive to quickly sealing the breach and preventing the breach from expanding.

[0065] Optimize the above technical solutions, such as Figure 3b and Figure 3c As shown, there are multiple counterweights 20, with two of them positioned on the bottom sides of the rectangular frame. This arrangement ensures that the weight on both sides of the fastener is equal, which helps the fastener remain stable during water flow impact and better secures the flood control materials, allowing them to quickly plug the breach. Preferably, the two counterweights 20 have equal weights.

[0066] In one embodiment, the metal mesh is at least one of reinforcing steel mesh or wire mesh; the reinforcing steel mesh or wire mesh is a standard component, which helps reduce costs, and the reinforcing steel mesh has high strength and corrosion resistance, which helps extend the service life of the metal mesh; it should be noted that the reinforcing steel mesh also has a certain weight, thus effectively preventing the fasteners from tipping over; it should also be noted that the wire mesh is lightweight, which is beneficial for the transportation of the embankment fasteners; and / or,

[0067] To increase the strength of the metal mesh, the metal mesh is a multi-layer mesh structure. Preferably, the steel mesh layer and the wire mesh can be arranged sequentially from the inside to the outside.

[0068] In one embodiment, the counterweight 20 and the blocking structure 10 are integrally formed; of course, the counterweight 20 and the blocking structure 10 can also be detachably installed. The bottom of the blocking structure 10 can be detachably installed with counterweights 20 of different weights. Both the counterweight 20 and the blocking structure 10 have a locking part to achieve detachable installation. The counterweight 20 is made of a high specific gravity metal, generally lead.

[0069] In one embodiment, the dam breach repair system further includes: a ship anchor and multiple anchoring ropes;

[0070] One end of the anchoring rope is connected to the counterweight 20 or the blocking structure 10, and the other end is connected to the ship's anchor. The ship's anchor and the anchoring rope fix the blocking structure 10 to prevent the fixing parts from being washed away by the water flow.

[0071] In one embodiment, such as Figure 4a and Figure 4b As shown, it also includes: a road and bridge structure 30 and a transport vehicle 50;

[0072] The road and bridge mechanism 30 includes: a hydraulic component 31 and a road and bridge assembly; the road and bridge assembly includes multiple road and bridge flat plates 32; wherein, the hydraulic component 31 is used for all-terrain balancing to keep the road and bridge flat plates 32 horizontally stable in rugged terrain;

[0073] Multiple road and bridge flat plates 32 are folded and connected in sequence so that the road and bridge assembly can have a folded state and a road and bridge state; wherein, a hydraulic component 31 is provided on the bottom surface of the road and bridge flat plate 32;

[0074] When the road and bridge mechanism is in the folded state, the road and bridge flatbeds 32 are stacked sequentially from bottom to top, with the bottom road and bridge flatbed 32 placed on the transport vehicle 50; when the road and bridge mechanism is in the road and bridge state, the road and bridge flatbeds 32 are connected end to end to form a road and bridge passage for vehicles, wherein the hydraulic components 31 are used to support the bottom surface of the road and bridge flatbeds 32; preferably, there are three road and bridge flatbeds 32, and two hydraulic components 31 are provided on the bottom surface of the road and bridge flatbeds 32, and the transport vehicle 50 is a multi-axle chassis vehicle.

[0075] In the above technical solution, when the road and bridge mechanism is in the folded state, the bottom road and bridge flatbed 32 is mounted on the transport vehicle 50. This facilitates the transport of the road and bridge components using the transport vehicle 50. Depending on the specific location of the dam breach, the components can be transported to the breach site. After reaching the breach site, the road and bridge flatbeds 32 can be quickly connected end-to-end to form a road and bridge passage for vehicles (such as standard rescue vehicles) to pass quickly. It should be noted that when the road and bridge mechanism is in the road and bridge state, all loads are borne by the hydraulic components 31; the frame of the transport vehicle 50 does not bear any load. It should also be noted that the road and bridge components can be flatbed, scissor, or telescopic, etc.

[0076] Optimize the above technical solutions, such as Figure 5a and Figure 5b As shown, the transport vehicle 50 can also carry the storage mechanism 41 and / or the conveying mechanism 42 to travel or be fixed on the road and bridge passage. Specifically, the storage mechanism 41 is a storage bin, and the conveying mechanism 42 is a telescopic belt conveyor. In operation, when a dam breach occurs, the road and bridge platform 32 and hydraulic components 31 of the road and bridge mechanism 30 are used to quickly form a road and bridge passage for vehicles. Then, the transport vehicle 50 carrying the storage mechanism 41 and the transport vehicle 50 carrying the conveying mechanism 42 use the road and bridge passage to reach the breached dam. The flood control material conveyed by the conveying mechanism 42 is used to seal the breach. Compared with the existing technology (where the transport vehicle 50 travels slowly due to poor road conditions at the breach, delaying the sealing opportunity), this solution can quickly seal the breach by coordinating the transport vehicle 50, the road and bridge passage, and the material conveying components, and avoids the need for large machinery (such as bulldozers or excavators used for road repair), which helps to save the cost of sealing the breach.

[0077] Further optimization of the above technical solution allows the telescopic belt conveyor to be adjusted arbitrarily according to the distance between the storage bin and the breach. The receiving end of the telescopic belt conveyor is a base with a funnel-shaped material collection port and a discharge port. Similar to a fire ladder, it is equipped with a hydraulic lifting platform. After unfolding, the position of the discharge port can be adjusted by rotating with the base to achieve flexible conveying.

[0078] In one embodiment, the top surface of the barrier structure 10 has an opening for inserting flood control material.

[0079] In one embodiment, the dam breach repair system further includes: a powered barge, a central control console, a gyroscope, and engineering equipment components. The powered barge serves as a water-land transfer station, cooperating with the road and bridge components. The gyroscope is connected to the central control console, and the gyroscope detects the hydraulic components 31, transmitting the detected information to the central control console. The central control console displays the flatness of the road and bridge flat plates 32 when the road and bridge mechanism is in road and bridge mode, so that the flatness of the road and bridge flat plates 32 can be adjusted at any time using the hydraulic components 31. The engineering equipment components include lifting equipment, excavating equipment, robotic arms, etc. This system is used to implement an emergency repair plan for dam breaches.

All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features.

[0081] The following is a further description of this solution with reference to specific embodiments:

[0082] This technical solution also has the following advantages:

[0083] I. Solving the problem of material transportation. Although materials can be transported through channels on dams or by water or air, transportation efficiency and speed will be greatly reduced in cases of rugged terrain and unpaved roads.

[0084] Second, address the problem of ineffective sealing of breaches in dikes due to rapid water flow and strong scouring force.

[0085] Third, develop standardized emergency sealing plans to reduce the time and economic costs of dike breach relief.
