Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically an emergency sealing device for the water inlet of a dam breach. Background Technology

[0002] In water conservancy projects, dikes are key infrastructure for flood control, water storage and water flow regulation. During long-term operation, dikes may develop through or semi-through seepage channels, or "holes," due to material aging, biological erosion or external damage. If not dealt with in time, these holes can easily lead to the erosion of the dike soil in a short period of time, resulting in catastrophic consequences such as dam failure.

[0003] Currently, the traditional methods for emergency sealing of water inlets in dam breaches mainly include the throwing method, which involves throwing large quantities of sandbags, quilts, stones, straw bales, and other materials near the water inlet to block the inlet or slow down the water flow through the accumulation of materials.

[0004] However, while traditional sealing methods are simple to operate, the use of materials such as sandbags, quilts, and straw bales is not only costly, but also difficult to fit tightly to the irregular outline of the leak. Furthermore, these traditional materials lack a fixing mechanism and are easily dispersed by the water flow, making them unreliable for effectively sealing the leak inlet. Utility Model Content

[0005] This utility model provides an emergency sealing device for the inlet of a dam breach. By inflating the airbag through an air supply pipe, the airbag expands and fits tightly against the irregular outline of the breach, thus quickly blocking the water flow. The airbag is mechanically fixed by the sealing plate, positioning tube, plug, and barbs. This solves the problems mentioned in the background art, such as the large consumption of traditional sealing materials, difficulty in tightly fitting the outline of the breach, lack of effective fixation, and unreliable sealing effect.

[0006] This utility model provides the following technical solution:

[0007] An emergency sealing device for a breach in a dam's inlet includes a sealing plate and an airbag fixedly connected to the sealing plate. The sealing plate is provided with an air passage component that works in conjunction with the airbag. Multiple positioning tubes are threaded onto the sealing plate. Each positioning tube has a plug installed at one end. The positioning tube has multiple sets of barbs and multiple sets of through holes. A driving component is provided inside the positioning tube to drive the barbs to slide along the through holes. The sliding direction of the through holes is perpendicular to the axis of the positioning tube.

[0008] As a preferred technical solution of this utility model, the air circuit component includes a one-way valve and an exhaust valve fixedly installed on the sealing plate. The exhaust end of the one-way valve and the air inlet end of the exhaust valve both extend into the airbag, and the air inlet end of the one-way valve is fixedly connected to an air supply pipe.

[0009] As a preferred technical solution of this utility model, the driving component includes a pressing rod threadedly connected to the positioning tube. A handwheel is fixedly connected to one end of the pressing rod outside the positioning tube. Multiple arc-shaped plates are connected inside the positioning tube through an elastic element. One end of the barb is fixedly connected to the arc-shaped plate. When the handwheel rotates, the end of the pressing rod inside the positioning tube slides over the surface of the arc-shaped plate.

[0010] As a preferred embodiment of this utility model, the elastic element includes multiple sets of springs fixedly installed on the inner wall of the positioning tube, and the arc-shaped plate is fixedly connected to the end of the spring away from the inner wall of the positioning tube.

[0011] As a preferred embodiment of this utility model, the number of barbs is 3-8 sets, and they are arranged in a ring at equal intervals on the circumference of the positioning tube.

[0012] As a preferred embodiment of this utility model, one end of the positioning tube is fixedly connected to a screw head, and the plug is threadedly connected to the screw head.

[0018] 1. In this emergency sealing device for the water inlet of a dam breach, air is supplied to the airbag through the air supply pipe, which expands and quickly covers the water inlet area and fits tightly to the irregular outline of the breach, thus achieving rapid blocking of water flow without the need for a large amount of sealing material, thereby improving the reliability and efficiency of dam emergency rescue.

[0019] 2. The emergency sealing device for the water inlet of the dam breach uses a sealing plate, positioning tube, plug, and barbs to mechanically fix the airbag, greatly improving its stability inside the breach and preventing it from being washed away by the water flow.

[0030] 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.

[0031] Example:

[0032] Reference Figures 1-7 An emergency sealing device for a dam breach inlet includes a sealing plate 1 and an airbag 2 fixedly connected to the sealing plate 1. The sealing plate 1 is equipped with an air passage component that works in conjunction with the airbag 2 to inflate or deflate. The airbag 2 includes an airtight layer 21, a reinforcing layer 22, and a protective layer 23. The reinforcing layer 22 is fixedly connected to one side of the airtight layer 21, and the protective layer 23 is fixedly connected to the side of the reinforcing layer 22 away from the airtight layer 21. The airtight layer 21 is made of butyl rubber, the reinforcing layer 22 is made of aramid fabric, and the protective layer 23 is made of thermoplastic polyurethane. The butyl rubber airtight layer 21 ensures that the airbag remains leak-free for extended periods under deep water pressure. The aramid fabric reinforcing layer 22 provides excellent tensile strength and burst resistance. The thermoplastic polyurethane protective layer 23 resists underwater sand and gravel friction and biological erosion. The cooperation of the airtight layer 21, the reinforcing layer 22, and the protective layer 23 ensures the effectiveness of the airbag 2. A sealing ring 9 is fixedly connected to one side of the sealing plate 1. The airbag 2 is located at the center of the sealing ring 9, which can improve the sealing performance of the device. Multiple positioning tubes 4 are threadedly connected to the sealing plate 1. The number of positioning tubes 4 is 3-6. This device takes 4 as an example and arranges them in a ring on the sealing plate 1. A plug 5 is installed at one end of the positioning tube 4. A screw head 51 is fixedly connected to one end of the positioning tube 4. The plug 5 is threaded onto the screw head 51. The plug 5 can be flexibly disassembled and assembled for maintenance and cleaning inside the positioning tube 4. Multiple sets of barbs 6 are provided on the positioning tube 4. The number of barbs 6 is 3-8 and they are arranged in a ring at equal intervals on the circumference of the positioning tube 4. This device takes 4 sets as an example to ensure the fixing effect of the airbag 2. Multiple sets of through holes 7 are opened through the positioning tube 4. The number of through holes 7 is the same as the number of barbs 6. A driving component is provided inside the positioning tube 4 to drive the barbs 6 to slide along the through holes 7. The sliding direction of the through holes 7 is perpendicular to the axis of the positioning tube 4.

[0033] Of course, in other embodiments, the air circuit includes a one-way valve 3 and an exhaust valve 32 fixedly installed on the sealing plate 1. The exhaust end of the one-way valve 3 and the air inlet end of the exhaust valve 32 both extend into the airbag 2. The air inlet end of the one-way valve 3 is fixedly connected to an air supply pipe 31. Here, the air inlet end of the air supply pipe 31 is connected to an air pump on the shore. The one-way valve 3 is used to allow the air source to enter the airbag 2 in one direction, while the exhaust valve 32 is provided to deflate the airbag 2.

[0034] Specifically, in use, professionals first put on diving equipment and fasten safety ropes, then dive into the water and seal the sealing plate 1 of this sealing device at the water inlet of the leak. Then, they notify the personnel on shore to supply air into the air supply pipe 31 through the air pump. The airflow in the air supply pipe 31 enters the airbag 2 through the one-way valve 3, causing the airbag 2 to inflate and expand inside the leak, quickly covering the water inlet area and closely fitting the irregular leak outline, thus achieving rapid blocking of water flow without consuming a large amount of sealing material, thereby improving the reliability and efficiency of emergency dam rescue.

[0035] The driving component includes a pressing rod 63 threadedly connected to the positioning tube 4. A handwheel 64 is fixedly connected to one end of the pressing rod 63 outside the positioning tube 4. Multiple arc-shaped plates 61 are connected inside the positioning tube 4 through elastic elements. The number of arc-shaped plates 61 is 3-8, and the device preferably has 4. One end of the barb 6 is fixedly connected to the arc-shaped plate 61. When the handwheel 64 is rotated, the end of the pressing rod 63 inside the positioning tube 4 slides over the surface of the arc-shaped plate 61. The elastic element includes multiple sets of springs 62 fixedly installed on the inner wall of the positioning tube 4. The number of springs 62 is 3-8, and the device preferably has 4. The arc-shaped plate 61 is fixedly connected to the end of the spring 62 away from the inner wall of the positioning tube 4. An anti-slip sleeve 8 is fixedly connected to the positioning tube 4. Anti-slip convex strips are fixedly connected to the surface of the anti-slip sleeve 8.

[0036] Specifically, after the airbag 2 inflates and fits tightly inside the hole, the anti-slip sleeve 8 can be rotated, which in turn drives the positioning tube 4 to rotate. Under the action of the thread, the plug 5 and the positioning tube 4 are deeply inserted into the soil of the dam. Then, the handwheel 64 and the squeezing rod 63 are rotated. Under the action of the thread, the squeezing rod 63 squeezes the arc plate 61 and drives the barb 6 to slide out along the through hole 7, so that the barb 6 is embedded in the soil in all directions to improve the anti-slip ability. Through the setting of the sealing plate 1, the positioning tube 4, the plug 5 and the barb 6, the airbag 2 can be mechanically fixed, which greatly improves its stability in the hole and prevents it from being washed away by the water flow. This achieves effective sealing of the water inlet of the hole and ensures the reliability of the sealing effect.
