Description

Technical Field

[0001] This invention belongs to the field of underwater emergency rescue and disaster relief technology, specifically relating to a spiral-shell type fire rescue device and method for underwater emergency disaster reduction. Background Technology

[0002] Dikes are an effective means of flood control. However, some dikes suffer from problems such as poor foundation conditions, poor dike construction quality, and numerous pits and ponds behind the dikes due to a lack of formal surveying and design in their early stages. During high water levels, these dikes are prone to seepage, seepage, and piping on the back slope, requiring localized reinforcement. In severe cases, dike breaches may even occur, leading to flood overflow and causing significant losses to people's lives and property. While some traditional dike emergency repair methods exist to address these dike risks, they often have limitations and drawbacks in practical application. Dike emergency repairs are mostly conducted under extreme conditions such as torrential rains and floods, where the situation is complex and time is of the essence. Although the "blocking in front, draining behind" principle is followed, traditional methods may fail due to various factors, such as difficulty in determining the inlet location during "blocking in front," the risk of materials being washed away, the large and rapid development of piping during "draining behind," poor dike management, or the presence of cavities caused by biological activity. These situations can be broadly categorized into two types:

[0003] In situations where a dike is already at risk but a breach has not yet occurred, where seepage and overtopping have already occurred, traditional emergency repair methods often involve using sandbags and other emergency materials to cover and plug leaks on the upstream slope, or raising the dam crest or constructing a secondary dike to prevent an "initial breach" from forming at the weak point after the floodwaters overflow. This initial breach would rapidly expand and eventually cause a major flood disaster. However, before the dike overflows or breaches, there is still some resource allocation capacity behind the dike, and measures should be taken promptly to contain the danger. In reality, however, upstream slope leaks are often deeply buried underwater, making their location difficult to detect. Furthermore, the rapid current upstream often washes away the coverings or sandbags used for plugging. Temporary dikes built with sandbags are also vulnerable to damage due to the rapid rise in floodwaters compared to the slower rise of the secondary dike or the secondary dike crest. Therefore, the actual risk of emergency repairs remains significant.

[0004] When a dike breach has occurred and a breach has formed, breach-sealing techniques are the primary measure to address the breach. Traditional methods include throwing sandbags and stones, using gabions, steel-timber composite structures, and sinking vehicles or boats. However, for dike breaches under such extreme conditions, traditional breach-sealing methods, lacking specific emergency response strategies, require significant manpower and resources, resulting in substantial economic losses. Furthermore, breach-sealing requires on-site guidance from professionals. When the breach occurs in an area with dense dikes, emergency responders may be unable to analyze the situation and take appropriate measures in a timely manner, posing a significant threat to their personal safety.

[0005] In summary, while the modern dike emergency response system is relatively mature, in practice, dike emergencies are often highly dangerous and located in remote areas. Traditional emergency supplies are difficult to mobilize quickly, and relying on sheer manpower means that a large number of personnel cannot reach the disaster site rapidly. Furthermore, the lack of professional guidance and modern equipment forces the use of traditional methods. A significant gap exists between the development of modern technology and traditional emergency response methods, highlighting the urgent need to develop simple emergency rescue equipment that can be operated by non-professional personnel. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention provides a spiral-shell type fire rescue equipment and method for underwater emergency disaster reduction. When a breach has not yet formed, water pressure is used to press the water-retaining plate onto the upstream slope of the dike, which can quickly seal the leak in the dike. By splicing multiple devices, the equipment can be stabilized on the upstream side of the dike, and the water-retaining plate can be used to quickly seal the breach, thus improving the efficiency of emergency rescue.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A spiral-shell type fire rescue device for underwater emergency disaster reduction includes a mounting platform, which is a hollow rigid plate structure; the mounting platform has a through-type air inlet inside.

[0009] The bottom of the mounting platform is equipped with an inflatable rubber bag;

[0010] The top of the mounting platform is equipped with an expandable water baffle, which includes a bottom fixed water baffle tube, a middle wound water baffle tube, and a tail weighted steel bar. The bottom fixed water baffle tube is fixed to the top of the mounting platform. The middle wound water baffle tube is fixedly connected to the bottom fixed water baffle tube and is set on the top of the mounting platform by winding, forming a volute shape. The tail weighted steel bar is fixed to the end of the middle wound water baffle tube.

[0011] Furthermore, the platform is symmetrically provided with inflation holes inside, and the bottom of the inflation holes is connected to the inside of an inflatable rubber bag.

[0012] Furthermore, an air valve is provided at the inlet of the inflation port.

[0013] Furthermore, a slope fixing ring is provided on one long side of the mounting platform.

[0014] Furthermore, the slope fixing ring is set on one side opposite to the unfolding direction of the unfoldable baffle plate, with one ring at each of the left and right ends.

[0015] Furthermore, the mounting platform is provided with a latch and a slot on both sides of its long side.

[0016] A method for using a spiral-shell type fire rescue device for underwater emergency disaster reduction includes two scenarios: when a seepage channel has formed in the dike, when a breach has not yet formed in the dike, and when a breach has already occurred in the dike.

[0017] Furthermore, for situations where seepage channels have already formed in the dike but breaches have not yet occurred, the specific methods are as follows:

[0018] Place the fully inflated fire rescue equipment in the river channel, and use a rope to connect the slope fixing ring as a tow rope to quickly pull the fire rescue equipment to the upstream side of the location of the hazard; after determining the approximate location of the leak, fix the rope connected to the slope fixing ring to the embankment railing, so that the fire rescue equipment floats stably on the upstream water surface at the location of the embankment hazard.

[0019] Push the deployable baffle plate, which sinks underwater under the drag of the weighted steel bar at the tail. Under the action of water pressure, the deployed baffle plate covers the leak point of the dike. Open the air valve on the air hole to release the gas in the inflatable rubber bag, thus completing the task of plugging the seepage channel of the dike.

[0020] Furthermore, regarding the situation where a breach has already occurred in the dike, the specific methods are as follows:

[0021] In river sections with smooth flow and small water surface fluctuations, multiple spiral-shaped fire rescue devices are assembled using the clamps and slots on both sides of the spiral-shaped fire rescue device; the assembled fire rescue device is then connected to the slope fixing ring via a rope as a traction rope and dragged to the upstream slope side of the breach section.

[0022] The fire rescue equipment is fixed to the bank slope on one side of the upstream boundary of the river section using a slope fixing ring. At the same time, the rope on the other side of the slope fixing ring is released. Driven by the water flow, the fire rescue equipment rotates around the fixed side until it collides and contacts the levee on the downstream side of the breach.

[0023] The slope fixing ring on the downstream side of the breach is quickly secured to the downstream slope with ropes, so that the rescue equipment is fixed and floating on the water surface upstream of the breach; the deployable water baffle on each spiral-shaped fire rescue equipment is pushed out and deployed. The deployable water baffle sinks underwater under the drag of the weighted steel bar at the tail. Under the action of water pressure, the deployed water baffle covers the embankment slope; the air valve on the air inlet is opened to release the gas in the inflatable rubber bag.

[0024] The beneficial effects of this invention are:

[0025] 1) Before a breach forms, this invention uses water pressure to press the water-blocking plate onto the upstream slope of the dike, which can quickly seal the leak point of the dike. This effectively solves the problem that it is difficult to determine the location of the leak point in the early stage of seepage and that it is impossible to effectively seal the leak point. It increases the sealing area and the sealing rate.

[0026] 2) By splicing multiple devices together, the present invention can stabilize the equipment on the upstream side of the dike to form a long and narrow disaster relief platform. This addresses the problem that the length of the dike breach is large and a single device cannot be stabilized on the upstream side of the dike to complete the disaster relief task. Furthermore, the invention utilizes water-blocking plates to quickly seal the breach, increasing the space for emergency rescue operations and improving the efficiency of emergency rescue.

[0027] 3) The present invention, through the design of the spiral-shaped expandable baffle, allows the equipment to be placed on the device when not in use, reducing the volume of disaster relief equipment and materials, increasing the flexibility of the equipment, improving the ease of use of the equipment in disaster relief applications, and improving the efficiency of dike reinforcement and disaster relief.

[0028] 4) The present invention uses a fixing ring and a weighted steel bar at the tail of the top water-blocking panel to fix the unfolded water-blocking panel on the upstream slope of the dike. The water pressure is used to press the water-blocking panel to achieve the effect of effectively sealing the leak.

[0029] 5) By venting the gas inside the rubber bag, the bottom of the entire device is pressed tightly against the slope, increasing the contact area between the baffle plate and the slope. When a breach has not yet formed, it blocks the seepage channel and improves the sealing effect. When a breach has formed, it can seal the breach to the maximum extent, improve the sealing effect, and reduce the amount of manual work in the later stage. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in detail with reference to specific embodiments.

[0037] This invention uses water pressure to press a water-retaining plate onto the upstream slope of the dike before a breach forms, which can quickly seal the leak in the dike. By splicing multiple devices together, the equipment can be stabilized on the upstream side of the dike, and the water-retaining plate can be used to quickly seal the breach, thus improving the efficiency of emergency rescue.

[0038] like Figure 1 , 2 As shown, the spiral-shell type fire rescue equipment for underwater emergency disaster reduction of the present invention includes a mounting platform 1, which is a rectangular hollow rigid plate structure; the mounting platform 1 has vertical through-type inflation holes 8 inside, which are symmetrically arranged on both sides, and an air valve 7 is provided at the inlet of the inflation hole 8; an inflatable rubber bag 9 is provided at the bottom of the mounting platform 1; the bottom of the inflation hole 8 is connected to the inside of the inflatable rubber bag 9. When the equipment is needed for emergency rescue, it can be quickly inflated into the bag by relying on the inflation hole 8 reserved in the middle area. After inflation, the inflation hole 8 is sealed with the air valve 7, so that the equipment can float stably on the water surface.

[0039] A slope fixing ring 2 is installed on one long side of the platform 1. The slope fixing ring 2 is located on the side opposite to the unfolding direction of the unfoldable water-retaining plate 6, with one ring at each of the left and right ends. The slope fixing ring 2 is used to bind the disaster relief equipment to the edge of the embankment slope.

[0040] The platform 1 is equipped with a deployable baffle 6 at its top. The deployable baffle 6 includes a bottom fixed baffle tube 3, a middle wound baffle tube 4, and a tail weighted steel rod 5. The bottom fixed baffle tube 3 is fixed to the top of the platform 1. The middle wound baffle tube 4 is fixedly connected to the bottom fixed baffle tube 3 and is set on the top of the platform 1 by winding, forming a volute shape. The tail weighted steel rod 5 is fixed to the end of the middle wound baffle tube 4. The platform 1 has a latch 10 and a slot 11 on both sides of its long side. The latch 10 and the slot 11 are embeddedly connected for splicing multiple devices.

[0041] The present invention relates to the method of using a spiral-shell type fire rescue device for underwater emergency disaster reduction, including two scenarios: when a seepage channel has formed in the dike, when a breach has not yet formed in the dike, and when a breach has already occurred in the dike.

[0042] 1) In the early stages of discovering a dike breach, it is often due to seepage channels forming on the upstream side of the dike, making it impossible to accurately pinpoint the leak point. Furthermore, the rapid currents at the breach location can easily wash away emergency supplies. This invention addresses situations where seepage channels have already formed but a breach has not yet occurred. The specific method is as follows:

[0043] Inflate the inflatable rubber bag 9 at the bottom of the equipment, place the inflated fire rescue equipment in the river, and use the rope to connect the slope fixing ring 2 as a towing rope to quickly pull the fire rescue equipment to the upstream side of the location of the hazard; after determining the approximate location of the leak, fix the rope connecting the slope fixing ring 2 to the fixed equipment such as the embankment slope railing, so that the fire rescue equipment floats stably on the upstream water surface at the location of the embankment hazard;

[0044] like Figure 5 As shown, the deployable water-blocking plate 6 is pushed, and dragged underwater by the weighted steel rod 5 at the tail, the deployable water-blocking plate 6 sinks under the water pressure. Under the action of water pressure, the deployed water-blocking plate tightly presses against the leak point of the dike, blocking the seepage channel. The air valve 7 on the air inlet 8 is opened to release the gas in the inflatable rubber bag 9, completing the task of sealing the seepage channel of the dike. By releasing the gas in the rubber bag, the bottom of the entire device is made to fit tightly against the slope, increasing the contact area between the water-blocking plate and the slope, and improving the sealing effect.

[0045] 2) In situations where dike breaches have occurred and large gaps have formed, considering that these breaches will rapidly expand and that a single piece of equipment lacks a fixed anchor point on the slope, making it impossible for the equipment to remain stable on the upstream side of the dike, this invention employs a multi-equipment assembly and joint operation disaster relief method. The specific method is as follows:

[0046] like Figure 3 , 4 As shown, in river sections with smooth flow and small water surface fluctuations, multiple spiral-shaped fire rescue devices can be assembled through the clamps 10 and slots 11 on both sides of the spiral-shaped fire rescue device to form a joint application device; the assembled fire rescue device is then connected to the slope fixing ring 2 as a traction rope and dragged to the upstream slope side of the breach section.

[0047] The fire rescue equipment is fixed to the bank slope on one side of the upstream boundary of the river section using the slope fixing ring 2. At the same time, the rope on the other side of the slope fixing ring 2 is released. Driven by the water flow, the fire rescue equipment rotates around the fixed side until it collides and contacts the levee on the downstream side of the breach.

[0048] The slope fixing ring 2 on the downstream side of the breach is quickly secured to the downstream slope with ropes, so that the rescue equipment is fixed and floating on the water surface upstream of the breach; the deployable water baffle 6 on each spiral-shaped fire rescue equipment is pushed and deployed. The deployable water baffle 6 is dragged underwater by the tail-weighted steel rod 5. Under the action of water pressure, the deployed water baffle tightly covers the embankment slope; the air valve 7 on the air inlet 8 is opened to release the gas in the inflatable rubber bag 9; by releasing the gas in the rubber bag, the bottom of the entire equipment is pressed tightly against the slope, increasing the contact area between the water baffle and the slope, improving the sealing effect, and reducing the amount of manual work in the later stage.

[0049] The specific number of linked devices in the combined application system is determined by the length of the breach, and should generally be two times the length of a single device longer than the breach length. The combined application system can be stably fixed on the upstream side of the breach, solving the problems of traditional disaster relief operations being limited to local platforms on both sides of the breach, resulting in limited space, low efficiency, and easy waste of valuable rescue time in the early stages of the breach. It increases the rescue operation space and shortens the rescue operation time.

[0050] In the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
