Description

Technical Field

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

[0002] The safety of dam projects is not only directly related to the safety of the project's benefits, but also to the safety of people's lives and property, the balance of the ecological environment, and social stability and prosperity. Therefore, we need to attach great importance to emergency rescue work, develop efficient emergency rescue equipment, and safeguard the lives and property of the people.

[0003] Currently, the main methods for sealing dike breaches include throwing sandbags and stones, using wire mesh gabions, steel-wood composite structures, and sinking vehicles and boats. These methods require rescue personnel or construction machinery such as excavators to pile sandbags and other sealing materials at the breach. Under extreme conditions, these traditional methods, especially when lacking specific solutions, consume a large amount of manpower and resources, resulting in high costs and jeopardizing the safety of rescue personnel. Furthermore, because dikes are typically narrow and long linear structures, the rescue operation area is usually limited to the left and right sides of the breach, significantly reducing efficiency. Finally, current rescue operations largely rely on a "human wave" approach, using manual relays to transport sandbags and other sealing materials to the rescue site. In practice, individual physical limitations and other factors can compromise the continuity of the operation, ultimately severely impacting efficiency and personnel safety. In summary, current emergency rescue methods have significant drawbacks. These methods not only increase rescue time but also cause substantial economic losses, wasting valuable time and potentially endangering the lives of rescue personnel. Therefore, there is an urgent need to conduct research and development on dike emergency rescue equipment and develop new automated rescue equipment. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a fire rescue equipment and method for underwater emergency disaster reduction, which can rapidly form a large-area emergency rescue operation platform within the upstream range of a dike breach, greatly improving the efficiency of emergency rescue; at the same time, it can also be flexibly assembled to achieve the rescue of people who have fallen into the water and reduce the losses caused by underwater disasters.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A fire rescue device for underwater emergency disaster reduction includes a frustum structure, wherein the frustum structure is a regular hexagonal structure, and convex clamps and concave grooves are arranged sequentially and spaced apart along the six faces of the frustum structure.

[0007] A hollow rubber dam bag is provided at the bottom of the frustum structure.

[0008] A connecting column is provided at the center of the top of the frustum structure, a disc is provided on the connecting column, and a rolling belt device is provided on the disc;

[0009] The convex clamp is embedded in the concave groove, enabling the interconnection of multiple fire rescue devices and forming a rescue operation platform in the upstream area of ​​the breach.

[0010] Furthermore, the convex caliper includes a ladder structure, which is connected to the frustum structure via a connecting rod.

[0011] Furthermore, the concave groove includes a latch and an elastic compressible structure. The latch is vertically arranged in the groove inside the frustum structure, and the upper and lower latches are symmetrically arranged. The exposed end of the latch is a bevel, and the other end is connected to the frustum structure through the elastic compressible structure. A trapezoidal space matching the shape of the convex caliper is formed between the upper and lower latches. A groove for accommodating the convex caliper is provided on the inner side of the latch.

[0012] Furthermore, the inner wall of the groove on the frustum structure for accommodating the convex caliper is provided with magnetic material, and the convex caliper is made of iron.

[0013] Furthermore, the connecting column is liftable, and the top of the frustum structure is provided with a cavity to accommodate the disk.

[0014] Furthermore, the rolling belt device includes a flexible lightweight steel belt and rollers on both sides.

[0015] Furthermore, the truncated pyramid structure has an internal cavity for installing a remote mobile control system.

[0016] Furthermore, the front end of the rubber hollow dam bag is provided with an air inlet.

[0017] Furthermore, the rear end of the rubber hollow dam bag is provided with swing blades.

[0018] A fire rescue method applied to underwater emergency disaster reduction, specifically as follows:

[0019] The rescue technicians will put the fire and rescue equipment into the river in distress and operate the air pump to quickly inflate the dam bag at the bottom of the fire and rescue equipment to ensure that the pressure inside the dam bag is stable and that the fire and rescue equipment meets the prescribed requirements for stable floating of the load on the water surface before starting the fire and rescue equipment.

[0020] For the rescue of people who have fallen into the water, depending on the actual needs, one or more fire rescue equipment are spliced ​​together and transported to the disaster area to rescue the people who have fallen into the water;

[0021] For the rescue operation at the breach location, multiple fire rescue equipment were moved to the upstream of the embankment where the breach was located using a remote control system. After reaching the upstream, three fire rescue equipment were moved to the location near the embankment upstream of the breach, and the fire rescue equipment was connected in pairs and fixed to the edge of the embankment slope using binding equipment. Other fire rescue equipment was then connected by impact.

[0022] The connecting column is raised to a specified height and rotated to connect the rolling belt equipment to form multiple material transport channels.

[0023] The beneficial effects of this invention are:

[0024] 1) This invention rapidly forms a large-area emergency rescue operation platform within the upstream area of ​​a dike breach, increasing the working surface and greatly improving rescue efficiency, thus minimizing the rescue time.

[0025] 2) This invention can connect multiple rescue devices to rescue people who have fallen into the water, increasing the number of people rescued at one time and improving rescue efficiency;

[0026] 3) By setting a rotating disc and pulley on the top of the equipment, the present invention can form multiple material transportation channels on the working platform. Furthermore, by using the rolling pulley, it can achieve the purpose of transporting sandbags and disaster relief boulders from multiple directions upstream of the breach, thereby improving the efficiency of material transportation and disaster relief operations. It avoids the traditional rescue method that relies on "human wave tactics", thus reducing the potential threat to the lives of rescue personnel.

[0027] 4) By setting a convex caliper and a concave groove, and setting a magnetic material on the inner wall of the groove, the caliper can be quickly embedded into the concave groove under the action of magnetic force, thus realizing the rapid impact splicing of two devices.

[0028] 5) This invention has a regular hexagonal structure, which can simultaneously realize the splicing of multiple devices, thus improving the splicing speed;

[0029] 6) This invention achieves the convenient movement of the equipment by using a bottom-inflated rubber dam bag structure, allowing it to float on the water surface; Attached Figure Description

Detailed Implementation

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

[0037] When a levee breaches, the levee management department is the first to receive the emergency response notification. Upon receiving the notification, the traditional approach is for the flood control station to quickly organize soldiers and other rescue personnel to reach both sides of the levee where the breach occurred. They then relay pre-prepared sandbags from both sides of the levee to the breach location. Depending on the development of the breach, they choose to lay the sandbags in layers, throw in boulders, or submerge large rescue vehicles and machinery. This method is very time-consuming, and the excessive manpower involved poses a significant threat to the lives of the rescue personnel.

[0038] Given that dikes are typically narrow and elongated linear structures, the emergency repair work area is usually limited to the left and right sides of the breach, resulting in a narrow rescue operation area. Based on the characteristics of water flow inside and outside the breach during a dike breach and the actual conditions of the dike, it was found that after the breach forms, the water level fluctuations inside and outside the breach are relatively stable in a short period of time. The water level height near the breach is basically stable at a certain value. Furthermore, the upstream area of ​​the breach region has a wide and large usable range, which has not been effectively utilized in the current emergency repair operation.

[0039] Therefore, taking the increase of the emergency rescue operation area as its starting point, this invention proposes a fire rescue equipment and method for underwater emergency disaster reduction. Because a dike breach quickly forms a relatively stable breach area in its early stages, typically within a range of 0-30m, this invention, to improve equipment flexibility, sets the equipment size to approximately 5×5m. To create a stable emergency rescue operation platform in the upstream area of ​​the breach, the assembly of multiple devices increases the operating area.

[0040] like Figure 1 , 2 As shown, the present invention includes a frustum structure 10, which is a regular hexagonal structure, and convex clamps 11 and concave grooves 6 are arranged sequentially and spaced apart along the six faces of the frustum structure 10.

[0041] The bottom of the truncated pyramid structure 10 is equipped with a hollow rubber dam bag 9. The front end of the hollow rubber dam bag 9 has an inflation hole 8, and the rear end has a swing blade 7. The hollow rubber dam bag 9 is made of a common material used in hydraulic engineering, known for its high strength and flexibility. Before the equipment is put into use, the hollow rubber dam bag 9 is in a contracted and tightly wrapped state, laid flat at the bottom of the equipment. After the emergency equipment is put into use, air can be injected into the dam bag 9 through the inflation hole 8 at the front end. The inflated dam bag forms a thin-walled hollow structure similar to the bottom of a boat, allowing the equipment to float on the water surface. A fishtail-like swing blade 7 is installed at the rear of the dam bag. The swinging of the blade 7 allows the equipment to move quickly to any position on the water surface, enabling rapid and free movement of the equipment near the dike. This also provides a prerequisite for increasing the emergency response area later.

[0042] A connecting column 14 is located at the center of the top of the frustum structure 10. A disc 3 is mounted on the connecting column 14, and a rolling belt device 15 is mounted on the disc 3. The rolling belt device 15 includes a flexible lightweight steel belt 1 and rollers 2 on both sides. The connecting column 14 is movable, and the top of the frustum structure 10 has a cavity 3 to accommodate the disc 3. When the connecting column 14 descends, the disc 3 falls into the cavity 3. The frustum structure 10 also has an internal cavity for installing a remote mobile control system.

[0043] like Figure 3 , 4 As shown, the convex caliper 11 is embedded in the concave caliper groove 6, enabling the interconnection of multiple rescue devices and forming a rescue operation platform in the upstream area of ​​the breach. The convex caliper 11 includes a ladder structure, which is connected to the frustum structure 10 via a connecting rod. The concave caliper groove 6 includes a latch 5 and an elastic compressible structure 4. In this embodiment, the elastic compressible structure 4 is a spring. The latch 5 is vertically arranged in the groove inside the frustum structure 10, with the upper and lower latches 5 symmetrically arranged. The exposed end of the latch 5 is a bevel, and the other end is connected to the frustum structure 10 via the elastic compressible structure 4. The latch 5 can extend and retract in the vertical direction. A trapezoidal space matching the shape of the convex caliper 11 is formed between the upper and lower latches 5. A groove for accommodating the convex caliper 11 is provided on the inner side of the latch 5.

[0044] The inner wall of the groove on the frustum structure 10 for accommodating the convex caliper 11 is provided with magnetic material, and the convex caliper 11 is made of iron. When the convex caliper 11 approaches the concave slot 6, under the action of the magnetic material inside the slot 6, the convex caliper 11 enters between the two latches 5; the elastic compressible structure 4 is squeezed and deformed, the latches 5 retract, the convex caliper 11 enters the slot 6, and is positioned by the latches 5.

[0045] This invention also provides a fire rescue method for underwater emergency disaster reduction, specifically:

[0046] Emergency rescue technicians deployed fire and rescue equipment into the distressed river and operated air pumps to quickly inflate the dam bags at the bottom of the equipment to ensure stable pressure inside the dam bags. Once the fire and rescue equipment met the required standard of stable floating of the load on the water surface, multiple fire and rescue devices were moved upstream of the breach location via a remote control system.

[0047] For the rescue of people who have fallen into the water, single or multiple fire rescue equipment can be combined and deployed to the disaster area to rescue the people who have fallen into the water, depending on the actual needs. Combining multiple fire rescue equipment can increase the number of people rescued at one time and improve the efficiency of the rescue.

[0048] For the rescue operation at the breach site, after reaching the upstream area, three fire rescue machines were moved to a position near the levee upstream of the breach. The machines were then connected in pairs using ropes and other common securing devices, and fixed to the edge of the levee slope. Other fire rescue machines were then used to achieve connection through impact. Ultimately, a stable emergency response platform was formed in the upstream area of ​​the breach, assembled as follows: Figure 5 As shown;

[0049] The connecting column 14 is raised to a designated height, and by rotating the connecting column 14, the rolling belt conveyors 15 are interconnected, forming multiple material transport channels. For example... Figure 5 As shown, in this embodiment, a trapezoidal working platform is formed to surround the breach; and six feeding ports are connected in the center of the working platform.

[0050] Downstream of the breach, a similar emergency response platform can be established. Rescue personnel deliver relief supplies to the initial end of a conveyor belt, which then transports the supplies upstream of the breach and into the water. When a sufficient volume of relief supplies has been delivered in a short period, the breach will gradually close over time. Once the breach is largely blocked, rescue personnel will quickly seal the remaining breach, ultimately achieving efficient, rapid, and unmanned modern flood control and rescue operations.
