Description

Technical Field

[0001] This invention relates to a flexible curtain device for rapid sealing of dike breaches, belonging to the field of flood control and emergency rescue technology. Background Technology

[0002] Emergency breach sealing of dikes is a crucial part of flood control. When a dike has already breached, the initial steps are usually to seal the breach at both ends to prevent further expansion, followed by filling the breach with sealing materials. However, sometimes high water levels, deep currents, and rapid flows mean that these emergency sealing measures take considerable time to become effective. Furthermore, the sealing work is relatively difficult, and improper execution can increase the weight on the dike, potentially causing it to collapse further. Therefore, a convenient and rapid breach sealing solution is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible curtain device for rapid sealing of dike breaches, which can quickly seal breaches when they occur, so as to facilitate further emergency rescue work.

[0004] The technical solution of the present invention is as follows:

[0005] A flexible curtain device for rapid sealing of dike breaches, characterized in that it comprises:

[0006] Several flexible curtain ribs are distributed in a fan-shaped interval;

[0007] The soft curtain is arranged along the distribution direction of the soft curtain ribs and fixed to them to form a fan-shaped structure;

[0008] Multiple pontoons are arranged at intervals and connected to the fan-shaped structure respectively;

[0009] The two pressure-bearing ends are fixed to the dikes on both sides of the breach and are connected to the left and right sides of the fan-shaped structure, respectively.

[0010] Using the above scheme, the entire device is fan-shaped, with the left and right sides fixed to the breached dike via pressure-bearing ends. The soft curtain extends laterally along the left and right sides of the fan-shaped structure and is arranged in the upper half of the soft curtain guide bars (i.e., the large arc end of the fan-shaped structure), while the lower half of the soft curtain guide bars (the small arc end of the fan-shaped structure) is in a cantilever state. When no emergency occurs, the entire device floats on the water surface under the action of the pontoons; when an emergency occurs, part of the pontoons detaches from the fan-shaped structure, and the large arc end of the entire fan-shaped structure flips downward, allowing the soft curtain to quickly seal the entire breach.

[0011] Furthermore, the fan-shaped structure also includes at least one arc-shaped metal frame, with both ends of the arc-shaped metal frame connected to two pressure-bearing ends respectively; the fan-shaped structure also includes at least one long chain, with both ends of the long chain connected to two pressure-bearing ends respectively; the long chain is arranged on the outside of the arc-shaped metal frame, and the long chain and the arc-shaped metal frame are distributed at the large arc end of the entire fan-shaped structure.

[0012] Using the above scheme, the long chain and the metal frame are arranged in an arc shape across the breach and are distributed at intervals. On the one hand, the arc-shaped metal frame has a certain toughness, which can strengthen the strength of the fan-shaped structure. On the other hand, when the water flow is rapid, the long chain can fluctuate irregularly to distribute the force and prevent the entire device from being damaged or deformed.

[0013] Furthermore, the soft curtain extends from the long chain to the arc-shaped metal frame, and the left and right sides of the soft curtain extend to the left and right sides of the fan-shaped structure, thus unfolding the entire soft curtain so that it can seal the breach in the event of an emergency.

[0014] Furthermore, the floats are divided into two groups. The first group of floats is arranged along the length of the arc-shaped metal frame and is evenly distributed between two adjacent soft curtain ribs. Similarly, the second group of floats is arranged along the length of the long chain and is evenly distributed between two adjacent soft curtain ribs. The even distribution of the floats ensures that the entire device can float on the water surface.

[0015] Furthermore, the first set of buoys is fixed to the arc-shaped metal frame, and the second set of buoys is connected to the fan-shaped structure via ropes. The ropes act as locking mechanisms, with one end fixed to a long chain of the fan-shaped structure and the other end having a slip buckle. The second set of buoys is threaded onto the corresponding ropes via rings, with the slip buckle located outside the ring to prevent it from slipping. The pull-out end of the slip buckle extends to the dike beside the breach.

[0016] Place the pull end of the rope loop on the dike, pull the pull end to open the loop, and loosen the rope. The ring of the second set of floats can slide down the rope with the water flow, causing the second set of floats to leave the entire device. Then the large arc end of the fan-shaped structure flips downward, that is, the long chain flips downward. However, the arc-shaped metal frame remains floating under the action of the first set of floats. At the same time, the soft curtain flips downward with the soft curtain channel to form a vertical interception state, quickly sealing the entire breach.

[0017] Furthermore, the flexible curtain guide is fixedly connected to the long chain. When the long chain fluctuates with the water flow, it will not slide along the flexible curtain guide, ensuring the deployment of the flexible curtain. The flexible curtain guide is movably connected to the arc-shaped metal frame, allowing the flexible curtain guide to flip relative to the arc-shaped metal frame. After the second set of floats falls off, the flexible curtain guide can flip, that is, the large arc end of the fan-shaped structure flips downward, and the flexible curtain is in an intercepting state.

[0018] Furthermore, the pressure-bearing end is constructed using a matrix frame formed by connecting several horizontal and vertical bars. Each connection point of the horizontal and vertical bars is equipped with a connecting ring (the two ends of a long chain are directly connected to the corresponding connecting ring, and the two ends of the arc-shaped metal frame are connected to the corresponding connecting ring via short chains). The rectangular frame is equipped with fixing rings; fixing bolts are inserted into the corresponding fixing rings to secure the rectangular frame to the ground of the dike. The multiple connecting rings allow for adjustment of the installation position of this device on the dike according to actual conditions.

[0019] This invention is simple and reasonable, easy to manufacture, and can quickly seal breaches and reinforce dikes. After the water flow slows down or, depending on the situation, the breach can be reinforced with soil or further emergency work can be carried out. Attached Figure Description

[0028] Example 1

[0029] like Figure 1 , 2 As shown, a flexible curtain device for rapid sealing of dike breaches includes several flexible curtain guides 1, flexible curtains 2, multiple pontoons (first group of pontoons 3, second group of pontoons 4) and two pressure-bearing ends 5.

[0030] Several flexible curtain reinforcements are arranged horizontally in a fan shape and distributed laterally along the breach. The flexible curtains are arranged along the distribution direction of the flexible curtain reinforcements and are fixed to them to form a fan-shaped structure. The two pressure-bearing ends are fixed to the levees on both sides of the breach and connected to the two ends of the fan-shaped structure respectively.

[0031] The fan-shaped structure also includes an arc-shaped metal frame 15 (in this embodiment, an arc-shaped steel bar) and a long chain 14. The two ends of the arc-shaped metal frame are connected to two bearing ends, and the two ends of the long chain are also connected to two bearing ends. The long chain 14 is distributed laterally in an arc shape and is arranged outside the arc-shaped steel bar. The long chain and the arc-shaped steel bar are distributed at the large arc end of the entire fan-shaped structure. The soft curtain covers the large arc end of the fan-shaped structure and is fixedly connected to the long chain and the arc-shaped steel bar.

[0032] The first group of buoys 3 is arranged along the length of the arc-shaped steel bars, positioned between two adjacent flexible curtain bars, and fixed to the arc-shaped steel bars; similarly, the second group of buoys 4 is arranged along the length of the long chain, positioned between two adjacent flexible curtain bars, and connected to the fan-shaped structure by ropes 6.

[0033] like Figure 3 , 4 As shown, each second group of buoys corresponds to a rope. One end of rope 6 is fixed to a long chain, and the other end has a slipknot 6-1. The second group of buoys 4 are threaded onto the corresponding rope through a ring 7, and the slipknot of the rope is located outside the ring of the second group of buoys to prevent the ring from slipping off the end of the rope. Figure 5 As shown, the solid line represents the pull-out end 6-2 of the snap fastener; pulling it downwards will release the snap fastener.

[0034] like Figure 3 As shown, place the pull end 6-2 of the rope buckle on the dike, pull the pull end by hand to open the buckle, and release the rope. The ring of the second set of floats can slide down from the end of the rope with the water flow. The second set of floats leaves the entire device, while the first set of floats remains floating. At this time, the large arc end of the soft curtain rib flips downward, and the soft curtain flips accordingly to a vertical interception state, quickly sealing the entire breach.

[0035] The flexible curtain ribs are movably connected to the curved steel bars. After the second set of floats detaches, the flexible curtain ribs can rotate relative to the curved steel bars, allowing the large arc end of the fan-shaped structure to flip downwards. For example... Figure 7 As shown, the flexible curtain rib 1 is welded with a bracket 8, and the arc-shaped steel bar is welded with a support 9. The bracket is inserted into the groove of the support and is rotated by a pin.

[0036] Example 2

[0037] Based on Example 1, the pressure-bearing end 5 is formed by connecting several horizontal and vertical bars to form a matrix frame. The rectangular frame is equipped with fixing rings 10. The rectangular frame is fixed to the ground of the embankment by inserting fixing bolts into the corresponding fixing rings.

[0038] Each horizontal and vertical bar connection point is equipped with a connecting ring 11 for connection. The two ends of the long chain are directly connected to the corresponding connecting ring, and the two ends of the curved steel bar are connected to the corresponding connecting ring through short chains 12.
