Description

Technical Field

[0001] The invention relates to a water conservancy engineering technology, in particular to a bank breach sealing method. Background Art

[0002] Embankments are water-retaining structures used in rivers or reservoirs. In some downstream rivers, due to the accumulation of silt, the riverbed is raised, so embankments need to be set up on both sides of the river to prevent the river from overflowing. In the flood season, the impact of rising water levels can easily lead to breaches in river embankments, and river water overflows to form disasters, posing a great threat to the safety of life and property on both sides of the river. For flood control and disaster relief, sealing embankment breaches is the key. However, the flow velocity at the breach is relatively large compared to the flow velocity of the river, and traditional plugging and restoration methods are difficult to take root in areas with high flow velocities, resulting in poor plugging and restoration effects.

[0003] The existing method of sealing breaches in river banks generally involves placing submerged objects. Some reports of disaster relief have even used sinking ships and cars to seal breaches, but this method is costly and is only used in emergency situations. In more cases, the sealing objects are placed in gabions, but gabions are usually small in size, so they are easily washed away by high-speed water after being placed in the breach, resulting in poor sealing effect.

[0004] There are various methods for rescuing river bank breaches in the prior art. For example, the applicant has applied for patent CN107447728B, which has disclosed a river breach blocking method based on array rocket drilling anchors, and CN202310297994.7, which has disclosed an array-type river breach blocking structure. However, the existing breach rescue methods all rely on the use of blocking objects to block the water flow for breach blocking and rescue. The blocking objects are required to forcibly counteract the impact of the water flow, and their blocking effect is limited and cannot be adjusted accordingly. When the impact of the breach water flow is large, the blocking objects are often easily washed away by the water flow, and the blocking effect is poor. Summary of the invention

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a bank breach sealing method with better sealing effect, which can adjust the sealing effect accordingly according to the size of the water flow, and at the same time is conducive to the formation of the sealing structure and improves the construction efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A method for sealing a embankment breach, wherein sealing materials are added to the embankment breach to seal the breach. The method is characterized in that, while adding the sealing materials, a reverse jet of water is used in front of the water flow leaking from the breach to hinder the outflow of water, thereby reducing the flow rate and flow rate of the water flow leaking from the breach until the sealing is completed.

[0007] In this way, during the plugging process, the water flow is sprayed in front of the breach to slow down the velocity and flow of the breach water flow, so that the plugging material is less impacted by the water flow after being added, and the plugging material is prevented from being directly washed away by the water flow, which is more conducive to the plugging material quickly forming a plugging structure at the breach and completing the closure of the breach. Therefore, the breach plugging effect and the efficiency of the plugging project construction are better improved.

[0008] During implementation, the core of this method is to apply an airflow impact in the opposite direction to the breach water flow when sealing the breach, so as to reduce the impact force of the water flow and improve the sealing effect. Therefore, the specific method of adding the sealing material in this process can be various methods and means for breach sealing and rescue in the prior art, including but not limited to the two breach sealing methods for which the applicant has applied for patents in the background technology, and various conventional embankment breach rescue and sealing methods.

[0009] Furthermore, as an alternative method, a drone is used to suspend the fan in front of the breach water flow to achieve reverse jetting of the water flow. This has a simpler structure, more direct wind output, and greater wind force. The disadvantage is that the fan is heavy, the drone consumes more power and is easily limited by the drone power. In addition, the connection and layout of the fan transmission line are inconvenient, which can easily cause instability.

[0010] As another option, the wind turbine is set on the embankment, and the wind outlet of the wind turbine is connected to the wind outlet device with a flexible wind duct. The wind outlet device is suspended by a drone in front of the breach water flow to achieve reverse jet injection of the water flow. In this way, the drone has a lower carrying weight, is more flexible and convenient to use and adjust, and is not restricted by power transmission lines. The disadvantage is that the wind loss is large through the wind duct connection.

[0011] Furthermore, the method is implemented through a UAV-assisted breach sealing system based on wind power of a wind turbine, wherein the UAV-assisted breach sealing system based on wind power of a wind turbine comprises a wind turbine, wherein the upper end of the wind turbine is suspended under the UAV by a sling, and the two sides of the wind turbine are connected to load-bearing devices relatively fixed to the embankments on both sides of the breach, and a remote control module is installed on the wind turbine.

[0012] In this way, when the system is used, the fan is hoisted to the front of the breach by the drone and adjusted to face the leaking water flow of the breach. Then the fan is remotely started to form a high-pressure air wall to block the water flow, cut off or reduce the flow rate and flow of the breach water flow. The fan recoil is borne by the load-bearing device and transferred to the embankments on both sides of the breach, so that the drone itself does not bear the fan recoil, ensuring the stability of the air wall. In this way, the system is used in conjunction with the rescue process of the embankment breach, which can slow down the impact of the water flow on the blocking object, greatly improve the effect and efficiency of the blocking, shorten the rescue time, and reduce the difficulty and danger of the rescue.

[0013] Furthermore, the sling is a sling rope, which is simpler and lighter.

[0014] Furthermore, the fan housing is rectangular, which makes it easier to splice and hang.

[0015] Furthermore, the fans are arranged in an array including at least one horizontal row, and the fans are fixed after being assembled. The upper surface of the top row of fans is connected to the drone through a suspension rope, and the two sides of each row of fans are connected to the load-bearing device. This makes it easier for the wind to blow out to form a wind curtain wall with sufficient area and strength to quickly eliminate the water potential of the breach and slow down the flow. This allows the solution to be flexibly adjusted according to the size of the breach, making it more suitable for implementation in cases where the breach width is larger.

[0016] Furthermore, at least one drone is connected to each wind turbine in the top row of wind turbines, so as to better ensure stability.

[0017] Furthermore, as a preferred embodiment, each fan is equipped with a battery as a power source for the fan, which can avoid wiring power supply and better ensure stability.

[0018] As another option, the wind turbine is connected to a power source installed on the embankment via wires. This can reduce the weight of the drone and extend the power supply time. During implementation, the wind turbine wires can be tied to the ropes in the load-bearing device to improve safety.

[0019] Furthermore, the load-bearing device includes a pull rope whose ends are connected to both sides of the fan, and also includes a embankment clamp that is clamped and fixed on the embankments on both sides of the breach, and the starting end of the pull rope is fixed on the embankment clamp. In this way, the embankment clamp is clamped and fixed on the embankment as a load-bearing basis, which facilitates the transfer of the recoil force of the fan's wind output to the embankment and ensures the stability of the fan when it is outputting wind.

[0020] Furthermore, the embankment clamp includes a clamp base located in the middle and a clamping body located at both ends of the clamp base. The clamp base and the clamping body are both long plate-like structures along the width direction of the embankment. One end of the clamping body is overlapped on the end of the clamp base and is connected to the clamp base in a sliding manner. A fixing structure for fixing after sliding is also provided between the end of the clamping body and the clamp base. The other end is folded downward by a leaf spring bent at ninety degrees and is clamped and fixed on the side wall of the embankment.

[0021] In this way, when installing, the clamp body is pulled apart along the clamp base so that the overall length of the clamp is adjusted to be consistent with the width of the embankment, and then the two ends can be fixed on the side wall of the embankment by means of the leaf spring. Because the side wall of the embankment is generally inclined at a certain angle, it is more convenient to open the leaf spring set at 90 degrees to achieve clamping, making it very convenient and quick to use, and it does not affect the normal use of the embankment to the greatest extent.

[0022] Furthermore, a sliding sleeve is fixedly provided upward on both sides of the clamp base in the width direction, and a slit is provided at the lower position inside the sliding sleeve. A sliding rod is fixedly provided upward on both sides of the clamping body in the width direction and slides in the sliding sleeve by means of the slit. The fixing structure includes at least one row of screw holes arranged along the length direction at the overlapping position of the clamping body and the clamp base, and also includes screws for fixing downward in the screw holes.

[0023] In this way, the sliding fit between the clamp body and the clamp base and the mutual fixation after the sliding fit are convenient, the structure is simple, the adjustment is quick, the fixation is reliable, and the main body of the clamp body and the clamp base is made to fit the embankment surface as much as possible without affecting the normal use of the embankment. The screws can be driven downward into the embankment surface, further improving the fixing effect of the embankment clamp.

[0024] Furthermore, the inner surface of the clamping plate is also convexly provided with claw nails, so as to better assist in clamping and fixing the clamping plate and prevent it from sliding upwards.

[0025] Furthermore, a rope-pulling motor is fixedly arranged on the clamp base along the length direction, and a wire drum is installed on the output shaft of the rope-pulling motor. A plurality of winding posts with lower ends fixed on the clamp base are arranged in parallel at intervals along the width direction of the clamp base on the side of the wire drum facing the breach, and the end of the rope is zigzag around each winding post and then wound around the wire drum.

[0026] In this way, after the embankment clamp is installed, the pull rope can be released to an appropriate length through the pull rope motor and the wire drum in advance, and the fan can be transported to an appropriate position for blowing with the help of the drone. When the fan blows, the recoil force is transmitted to each winding column through the pull rope, and the winding column shares the force, thus protecting the pull rope motor.

[0027] Furthermore, the rope-pulling motor is a self-locking motor, which better ensures the stability of the rope when stopped.

[0028] As another option, the present method is implemented through a UAV-assisted breach sealing system based on duct wind power, wherein the UAV-assisted breach sealing system based on duct wind power includes a blower fixed on the embankments on both sides of the breach, the air outlet end of the blower is connected to a flexible air duct, the air outlet end of the air duct is installed on an air outlet device, the air outlet device is suspended under the UAV by a sling, and the two sides of the air outlet device are connected to load-bearing devices relatively fixed to the embankments on both sides of the breach.

[0029] In this way, when the system is used, the air outlet device is hoisted by the drone to the position in front of the breach facing the leaking water flow, and then the fan is started. The wind flows through the air duct to the front of the breach and blows out to form a high-pressure air wall to hinder the water flow, cut off or reduce the flow rate and flow of the breach. The recoil of the air outlet of the air duct is borne by the load-bearing device and transferred to the embankments on both sides of the breach, so that the drone itself does not bear the recoil of the air outlet, ensuring the stability of the air wall. In this way, the system is used in conjunction with the rescue process of the embankment breach, which can slow down the impact of the water flow on the blocking object, greatly improve the effect and efficiency of the blocking, shorten the rescue time, and reduce the difficulty and danger of the rescue.

[0030] Furthermore, the air outlet device includes an air duct mounting frame, the front end of the air duct mounting frame is provided with a vertically arranged rectangular air outlet frame, the upper and lower side panels of the air outlet frame are respectively provided with a slide groove that passes through up and down along the length direction, a sliding plate is respectively provided on the left and right sides of the air outlet frame, and a bolt is respectively fixedly provided with a bolt at the upper and lower ends of the sliding plate along the vertical direction, the bolt can be slidably fitted in the slide groove and pass through the slide groove, the part of the bolt passing through the slide groove is screwed with a nut to achieve fixation, and the two sides of the air outlet frame are connected to the draw rope of the load-bearing device; the middle part of the rear end of the air duct mounting frame is provided with a horizontally arranged air inlet tube, the outer end of the air inlet tube is fixedly connected to the air duct, the inner end of the air inlet tube is connected to the small diameter end of a pipe sleeve that is an integral trumpet-shaped, the pipe sleeve is made of (high) elastic material, the front end of the pipe sleeve is arranged in the air outlet frame, and the left and right sides are fit and fixed on the inner side surface of the sliding plate.

[0031] In this way, the air duct delivers the air flow to the air inlet, and then after being expanded by the pipe sleeve, it is blown out from between the two sliding plates in the air outlet frame to form a wind curtain air wall to block the water flow from the breach. The width of the air outlet can be adjusted according to the on-site conditions to match the width of the breach, thereby better ensuring the effect of blocking the water flow leaking from the breach.

[0032] Furthermore, the sliding plate is in an arc shape that bulges outwards on both sides as a whole, so that it can be better fitted and fixed with the pipe sleeve.

[0033] Furthermore, the sling is a sling rope, which is simpler and lighter.

[0034] Furthermore, a drone is connected upwards to the left and right sides of the upper end of the air outlet frame, and a drone is connected upwards to the upper end of the air inlet tube. This can better maintain the stability of the air outlet device.

[0035] Furthermore, the load-bearing device includes a pull rope whose ends are connected to both sides of the air outlet frame, and the starting end of the pull rope is connected to an anchoring device anchored in the riverbed inside the embankment on both sides of the breach.

[0036] In this way, because the air outlet device is at a height level with or slightly lower than the upper surface of the embankment when working, the other end of the pull rope is fixed to the riverbed inside the embankment by an anchoring device. The pull rope will fit the upper surface of the embankment and then be pulled outward to connect to the air outlet device. Therefore, most of the air outlet recoil will be borne by the embankment, and the anchoring device will be less stressed, which can better ensure stability. This solution is more suitable for implementation in cases where the breach width is relatively small.

[0037] Furthermore, the anchoring device is a rocket drilling anchor. The rocket drilling anchor is a patented product developed by the applicant and can better ensure the reliability of anchoring.

[0038] The present invention has the following innovations: 1. High-pressure air wall technology is used to quickly eliminate the water potential of the breach and slow down the flow. The powerful airflow of the high-pressure air wall is ejected at a very high speed and collides head-on with the turbulent water flow. Due to the compressibility and high energy transfer characteristics of the gas, the water flow speed can be greatly reduced at the moment of contact with the breach water flow, and the flow energy of the water is quickly consumed, thereby realizing rapid and effective control of the water potential of the breach. When a breach occurs, a powerful high-pressure airflow is generated through advanced compression technology. These airflows are ejected in a specific way, and a tight and powerful air curtain is instantly formed at the breach. This air curtain can directly act on the turbulent water flow and quickly eliminate the impact of the water potential. Its powerful thrust can effectively slow down the speed of the water flow and reduce the kinetic energy of the water, thereby making the turbulent water flow gentle. 2. The unique design of the high-pressure air wall enables it to adapt to breaches of different sizes and flow rates. By adjusting the pressure, injection speed and injection area of ​​the gas, the strength and range of action of the air wall can be accurately controlled. For larger breaches, multiple sets of high-pressure air wall devices can be used to work together to form a continuous and powerful protection belt to ensure that the water potential is fully and effectively contained.

[0039] In summary, this method can rely on wind flow to form a high-pressure air wall to block the water flow from the breach, can quickly eliminate the water potential of the breach, slow down the flow, and solve the problem of the difficulty of landing of conventional thrown objects caused by the high flow rate of river breaches. At the same time, the wind flow can be easily adjusted according to the water flow of the breach, so that it can be better used for blocking different breaches. The wind flow forms an air wall and cooperates with the addition of plugging materials to achieve breach blocking, which is conducive to the formation of the blocking structure and improves the efficiency of breach repair and blocking. Rapid, safe, economical and efficient breach blocking is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] Embodiment 1: A method for sealing a embankment breach, wherein sealing materials are added to the embankment breach to seal the breach. The method is characterized in that, while adding the sealing materials, a reverse jet of water is used in front of the breach to block the outflow of water, thereby reducing the velocity and flow of the breach water until the sealing is completed.

[0048] In this way, during the plugging process, the water flow is jetted directly in front of the breach to slow down the velocity and flow of the breach water flow, so that the impact of the water flow on the plugging material after it is added is reduced, and the plugging material is prevented from being directly washed away by the water flow, which is more conducive to the plugging material quickly forming a plugging structure at the breach and completing the closure of the breach. Therefore, the breach plugging effect and the efficiency of the plugging project construction are better improved. During implementation, the core of this method is to apply an airflow impact in the opposite direction to the breach water flow when the breach is plugged, so as to reduce the impact force of the water flow and improve the plugging effect. Therefore, the specific way of adding the plugging material in this process can be various ways and methods of breach plugging rescue in the prior art, including but not limited to the two breach plugging methods for which the applicant has applied for patents in the background technology, and various conventional embankment breach rescue plugging methods.

[0049] In this embodiment, a drone is used to suspend the fan to the front of the breach water flow to achieve reverse jet injection of the water flow. This has a simpler structure, more direct wind output, and greater wind force. The disadvantage is that the fan is heavy, the drone consumes more power and is easily limited by the drone power. In addition, the connection and layout of the fan transmission line are inconvenient, which can easily cause instability.

[0050] Specifically, this embodiment is implemented by a UAV-assisted breach sealing system based on wind power of a wind turbine, see Figure 1-Figure 4As shown, the UAV-assisted breach sealing system based on wind power of a wind turbine includes a wind turbine 1, the upper end of which is suspended under a UAV 2 by a sling, and both sides of the wind turbine 1 are connected to load-bearing devices relatively fixed to the embankments on both sides of the breach, and a remote control module is installed on the wind turbine 1.

[0051] In this way, when the system is used, the fan is hoisted to the front of the breach by the drone and adjusted to face the leaking water flow of the breach. Then the fan is remotely started to form a high-pressure air wall to block the water flow, cut off or reduce the flow rate and flow of the breach water flow. The fan recoil is borne by the load-bearing device and transferred to the embankments on both sides of the breach, so that the drone itself does not bear the fan recoil, ensuring the stability of the air wall. In this way, the system is used in conjunction with the rescue process of the embankment breach, which can slow down the impact of the water flow on the blocking object, greatly improve the effect and efficiency of the blocking, shorten the rescue time, and reduce the difficulty and danger of the rescue.

[0052] Wherein, described sling is sling rope 3. This is simpler and lighter.

[0053] The housing of the fan 1 is rectangular, which makes it easier to splice and hang.

[0054] The fan 1 is an array arrangement including at least one horizontal row, and the fans are fixed after being assembled. The upper surface of the top row of fans is connected to the drone 2 upward through the suspension rope 3, and the two sides of each row of fans are connected to the load-bearing device. This makes it easier for the wind to blow out to form a wind curtain wall with sufficient area and strength, so as to quickly eliminate the water potential of the breach and slow down the flow. This allows the scheme to be flexibly adjusted according to the size of the breach, making it more suitable for implementation in cases where the breach width is larger.

[0055] Among them, at least one drone is connected above each fan in the top row of fans 1. This can better ensure stability.

[0056] During implementation, as an optional method, each fan 1 is equipped with a battery as a fan power source, which can avoid wiring power supply and better ensure stability.

[0057] During implementation, as another optional method, the wind turbine 1 is connected to a power source installed on the embankment through an electric wire. This can reduce the weight of the drone and extend the power supply time. During implementation, the wind turbine wire can be bound and connected to the pull rope in the load-bearing device to improve safety.

[0058] The load-bearing device includes a pull rope 4 whose ends are connected to both sides of the fan, and also includes a embankment clamp that is clamped and fixed on the embankments on both sides of the breach, and the starting end of the pull rope 4 is fixed on the embankment clamp. In this way, the embankment clamp is clamped and fixed on the embankment as a load-bearing basis, which facilitates the transfer of the recoil force of the fan to the embankment and ensures the stability of the fan when it is discharging air.

[0059] Among them, the embankment clamp includes a clamp base 5 located in the middle and a clamping body 6 located at both ends of the clamp base. The clamp base 5 and the clamping body 6 are both long plate-like structures along the width direction of the embankment. One end of the clamping body 6 is overlapped on the end of the clamp base and is connected to the clamp base by sliding cooperation. A fixing structure for fixing after sliding is also provided between the end of the clamping body 6 and the clamp base 5. The other end is folded downward by a leaf spring 7 bent at ninety degrees and is provided with a clamping plate 8 and clamped and fixed on the side wall of the embankment.

[0060] In this way, when installing, the clamp body is pulled apart along the clamp base so that the overall length of the clamp is adjusted to be consistent with the width of the embankment, and then the two ends can be fixed on the side wall of the embankment by means of the leaf spring. Because the side wall of the embankment is generally inclined at a certain angle, it is more convenient to open the leaf spring set at 90 degrees to achieve clamping, making it very convenient and quick to use, and it does not affect the normal use of the embankment to the greatest extent.

[0061] Among them, a sliding sleeve 9 is fixed upward on both sides of the clamp base 5 in the width direction, and a slit is provided at the lower position inside the sliding sleeve 9. A sliding rod 10 is fixed upward on both sides of the width direction of the clamping body and slides in the sliding sleeve by means of the slit. The fixing structure includes at least one row of screw holes arranged along the length direction at the overlapping position of the clamping body and the clamp base, and also includes screws 12 for fixing downward in the screw holes.

[0062] In this way, the sliding fit between the clamp body and the clamp base and the mutual fixation after the sliding fit are convenient, the structure is simple, the adjustment is quick, the fixation is reliable, and the main body of the clamp body and the clamp base is made to fit the embankment surface as much as possible without affecting the normal use of the embankment. The screws can be driven downward into the embankment surface, further improving the fixing effect of the embankment clamp.

[0063] Among them, the inner surface of the clamping plate 8 is also convexly provided with claw nails 13. This better assists in clamping and fixing the clamping plate to avoid sliding upwards.

[0064] Among them, a rope-pulling motor 14 is fixedly arranged on the clamp base 5 along the length direction, and a wire drum 15 is installed on the output shaft of the rope-pulling motor 14. The wire drum 15 faces the breach and has multiple winding posts 16 whose lower ends are fixed on the clamp base and are arranged in parallel at intervals along the width direction of the clamp base. The end of the pull rope 4 is wound around each winding post 16 in a zigzag manner and is connected to the wire drum.

[0065] In this way, after the embankment clamp is installed, the pull rope can be released to an appropriate length through the pull rope motor and the wire drum in advance, and the fan can be transported to an appropriate position for blowing with the help of the drone. When the fan blows, the recoil force is transmitted to each winding column through the pull rope, shared by the winding column and transmitted to the embankment through the clamp base, thus protecting the pull rope motor.

[0066] Wherein, the rope-pulling motor 14 is a self-locking motor, which better ensures the stability of the rope when stopping.

[0067] Implementation 2: The difference between Implementation 2 and Implementation 1 is that in this method, the fan is set on the embankment, the outlet end of the fan is connected to the outlet device with a flexible air duct, and the outlet device is suspended by a drone to the front of the breach water flow to achieve reverse jetting of the water flow. In this way, the drone has a lower carrying weight, is more flexible and convenient to use and adjust, and is not restricted by power transmission lines. The disadvantage is that the wind loss is large through the air duct connection.

[0068] Specifically, this embodiment is implemented by a UAV-assisted breach sealing system based on wind power of the air duct, see Figure 5 and Figure 6 The UAV-assisted breach sealing system based on duct wind force includes a blower 21 fixed on the embankments on both sides of the breach, the air outlet end of the blower 21 is connected to a flexible air duct 22, the air outlet end of the air duct 22 is installed on an air outlet device, the air outlet device is suspended under the UAV 23 by a sling, and the two sides of the air outlet device are connected to the load-bearing devices relatively fixed on the embankments on both sides of the breach.

[0069] In this way, when the system is used, the air outlet device is hoisted by the drone to the position in front of the breach facing the leaking water flow, and then the fan is started. The wind flows through the air duct to the front of the breach and blows out to form a high-pressure air wall to hinder the water flow, cut off or reduce the flow rate and flow of the breach. The recoil of the air outlet of the air duct is borne by the load-bearing device and transferred to the embankments on both sides of the breach, so that the drone itself does not bear the recoil of the air outlet, ensuring the stability of the air wall. In this way, the system is used in conjunction with the rescue process of the embankment breach, which can slow down the impact of the water flow on the blocking object, greatly improve the effect and efficiency of the blocking, shorten the rescue time, and reduce the difficulty and danger of the rescue.

[0070] The air outlet device includes an air duct mounting frame 24, the front end of which is provided with a vertically arranged rectangular air outlet frame 25, and the upper and lower side panels of the air outlet frame 25 are respectively provided with a slide groove 26 that passes through from top to bottom along the length direction, and a sliding plate 27 is respectively provided on the left and right sides of the air outlet frame, and a bolt 28 is respectively fixedly provided at the upper and lower ends of the sliding plate along the vertical direction, and the bolt can be slidably fitted in the slide groove and pass through the slide groove 26, and the part of the bolt passing through the slide groove is screwed with a nut to achieve fixation, and the two sides of the air outlet frame 25 are connected to the pull rope 29 of the load-bearing device; the middle part of the rear end of the air duct mounting frame 24 is provided with a horizontally arranged air inlet tube 30, the outer end of the air inlet tube 30 is fixedly connected to the air duct 22, and the inner end of the air inlet tube 30 is connected to the small diameter end of a tube sleeve 31 that is an integral trumpet-shaped, and the tube sleeve 31 is made of (high) elastic material, and the front end of the tube sleeve 31 is arranged in the air outlet frame 25 and the left and right sides are fixed on the inner side of the sliding plate 27.

[0071] In this way, the air duct delivers the air flow to the air inlet, and then after being expanded by the pipe sleeve, it is blown out from between the two sliding plates in the air outlet frame to form a wind curtain air wall to block the water flow from the breach. The width of the air outlet can be adjusted according to the on-site conditions to match the width of the breach, thereby better ensuring the effect of blocking the water flow leaking from the breach.

[0072] The sliding plate 27 is in an arc shape that bulges outwards on both sides as a whole, so that it can be better fitted and fixed with the pipe sleeve.

[0073] Wherein, described sling is sling 32. This is simpler and lighter.

[0074] Among them, the left and right sides of the upper end of the air outlet frame are each connected upward with a drone 23, and the upper end of the air inlet tube is connected upward with a drone. In this way, the stability of the air outlet device can be better maintained.

[0075] The load-bearing device includes a pull rope 29 whose ends are connected to both sides of the air outlet frame, and the starting end of the pull rope is connected to an anchoring device 33 anchored in the riverbed inside the embankment on both sides of the breach.

[0076] In this way, because the air outlet device is at a height level with or slightly lower than the upper surface of the embankment when working, the other end of the pull rope is fixed to the riverbed inside the embankment by an anchoring device. The pull rope will fit the upper surface of the embankment and then be pulled outward to connect to the air outlet device. Therefore, most of the air outlet recoil will be borne by the embankment, and the anchoring device will be less stressed, which can better ensure stability. This solution is more suitable for implementation in cases where the breach width is relatively small.

[0077] The anchoring device 33 is a rocket drilling anchor, which is a patented product developed by the applicant and can better ensure the reliability of anchoring.

[0078] Implementation method three: Implementation method three is substantially the same as implementation method one, with the only difference being that the load-bearing device used in this implementation method is the same as that used in implementation method two, and the rest of the parts remain consistent with implementation method one.

[0079] Implementation method 4: Implementation method 4 is substantially the same as implementation method 2, with the only difference being that the load-bearing device used in this implementation method is the same as that in implementation method 1, and the rest of the parts remain consistent with implementation method 2.

[0080] Embodiment 5: Embodiment 5 is similar to Embodiment 2, except that a compressed gas tank or a gas liquefied tank is used instead of a blower as the gas source. In this case, the impact force generated by the airflow is greater and easier to control.

[0081] When implemented, the present invention has the following application prospects: 1. Flood prevention and disaster reduction: When an emergency disaster such as a river breach occurs, the method can effectively slow down the water flow speed, reduce the impact force of the flood, buy precious time for subsequent rescue and blocking of the breach, and reduce the loss of life and property caused by the flood. Compared with traditional flood control methods, high-pressure gas walls have significant advantages. They have an extremely fast response speed and can be quickly deployed and play a role in a short period of time, buying precious time for rescue. Secondly, the operation of high-pressure gas walls is relatively simple and does not require a large amount of manpower and complex equipment preparation, which reduces the difficulty of operation and labor costs. Furthermore, since it uses gas as a working medium, it will not cause additional pollution and damage to the environment, which meets the requirements of sustainable development. 2 Maintenance of water conservancy projects: It helps to control the water flow when local damage or failure occurs in water conservancy projects, and facilitates the maintenance and reinforcement of the project.
