Description

Technical Field

[0001] The present invention belongs to the technical field of underwater emergency rescue and disaster relief, and in particular relates to firefighting and rescue equipment and a method for underwater emergency disaster relief. Background Art

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

[0003] At present, the main means of plugging dike breaches are throwing sandbags and stones, wire mesh gabions, steel-wood composite frames, sinking vehicles and ships, etc. Rescue workers or construction machinery such as excavators need to stack sandbags and other plugging materials at the breach. Traditional plugging rescue methods under extreme conditions require a lot of manpower and material resources when there is a lack of targeted rescue methods. The rescue cost is high and the safety of rescue workers cannot be effectively guaranteed. In addition, since dikes are usually narrow and long linear structures, after the dike is in danger, the rescue operation surface is usually only on the left and right sides of the breach, and the rescue operation surface is narrow, which greatly reduces the rescue efficiency. Finally, most of the current rescue operation methods still need to use the "human sea tactics" to transport sandbags and other plugging materials to the rescue operation through manual relay. In the actual operation process, due to various reasons such as personal physical strength, the continuity of the rescue cannot be guaranteed, which will eventually seriously affect the rescue efficiency and personnel safety. In summary, the existing emergency rescue methods have major drawbacks. The emergency rescue methods will not only increase the rescue time, but also cause great economic losses. While delaying the precious rescue time, it may also endanger the lives of rescue personnel. Therefore, it is urgent to carry out research on embankment rescue equipment and develop new rescue automation equipment. Summary of the invention

DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with specific implementation modes.

[0037] When a breach occurs in a dike, the dike management department will first receive an emergency rescue notice. After receiving the notice, the traditional way of operation is that the flood control management station will quickly organize people's soldiers and other disaster relief personnel to arrive at both sides of the dike where the breach occurs, and transport the rescue sand and gravel bags prepared in advance on both sides of the dike to the breach location through relay. According to the development of the breach, the sand and gravel flood control bags are laid layer by layer, and boulders are thrown or large rescue vehicles and machinery are sunk. This method is very time-consuming, and too much manpower investment will pose a great threat to the lives and safety of rescue personnel.

[0038] As levees are usually narrow and long linear structures, the levee rescue operation surface is usually only on the left and right sides of the breach, which leads to the problem of a narrow rescue operation surface. Combined with the characteristics of water flow inside and outside the breach when the levee breaks and the actual situation of the levee, it is found that after the breach is formed, the water level fluctuations inside and outside the breach are relatively stable in a short period of time, and the water level height near the breach is basically stable at a certain value. In addition, the upstream of the breach area has a wide range and large area, which has not been effectively utilized in the current rescue operations.

[0039] Therefore, starting from increasing the rescue operation surface, the present invention proposes a fire rescue equipment and method for underwater emergency disaster reduction. Because the levee breach will quickly form a relatively stable breach range at the beginning of development, the range is often within the range of 0 to 30 meters. In order to improve the flexibility of the equipment, the present invention sets the equipment size to basically 5×5 meters, so as to form a stable rescue operation platform in the upstream area of ​​the breach, and achieve the purpose of increasing the operation surface by assembling multiple devices.

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

[0041] A rubber hollow dam bag 9 is arranged at the bottom of the prism structure 10, an inflation hole 8 is arranged at the front end of the rubber hollow dam bag 9, and a swinging blade 7 is arranged at the rear end of the rubber hollow dam bag 9. The material of the rubber hollow dam bag 9 is selected from the rubber dam bag material commonly used in water conservancy projects, which has the advantages of high strength and good flexibility; before the equipment is put into use, the rubber hollow dam bag 9 is in a shrunken and tightly wrapped state, and is laid flat on the bottom of the equipment; when the rescue equipment is put into use, the dam bag 9 can be inflated through the inflation hole 8 arranged at the front end of the dam bag 9, and the inflated dam bag will form a thin-walled hollow structure similar to the bottom structure of a ship, and the inflated equipment can float on the water surface; a blade 7 that can swing around an axis similar to a fish tail is installed at the tail position of the dam bag, and the swing of the blade 7 can drive the equipment to move quickly to any position on the water surface, so that the equipment can be quickly and freely moved near the embankment, and it also provides a precondition for increasing the rescue operation surface in the later stage;

[0042] A connecting column 14 is provided at the center of the top of the prism structure 10, on which a disc 3 is provided, and on which a rolling belt device 15 is provided, and the rolling belt device 15 includes a flexible light steel belt 1 and rollers 2 on both sides. The connecting column 14 can be raised and lowered, and a cavity 3 for accommodating the disc 3 is provided at the top of the prism structure 10. When the connecting column 14 descends, the disc 3 falls into the cavity 3. A cavity is provided inside the prism structure 10 for installing a remote mobile control system.

[0043] like Figure 3 , 4 As shown, the convex caliper 11 is embedded in the concave slot 6 to achieve the interconnection of multiple rescue equipment and form a rescue operation platform in the upstream area of ​​the breach. The convex caliper 11 includes a step structure, and the step structure is connected to the prism structure 10 through a connecting rod. The concave slot 6 includes a tongue 5 and an elastic compressible structure 4. In this embodiment, the elastic compressible structure 4 is a spring. The tongue 5 is vertically arranged in the inner groove of the prism structure 10, and the upper and lower tongues 5 are symmetrically arranged; the exposed end of the tongue 5 is an inclined surface, and the other end is connected to the prism structure 10 through the elastic compressible structure 4; the tongue 5 can be extended and retracted in the vertical direction; a trapezoidal space matching the outer shape of the convex caliper 11 is formed between the upper and lower tongues 5; a groove for accommodating the convex caliper 11 is arranged on the inner side of the tongue 5.

[0044] The inner wall of the groove for accommodating the male clamp 11 on the prism structure 10 is provided with magnetic material, and the male clamp 11 is made of iron. When the male clamp 11 is close to the female clamping slot 6, under the action of the magnetic material inside the clamping slot 6, the male clamp 11 enters between the two clamping tongues 5; the elastic compressible structure 4 is squeezed and deformed, the clamping tongue 5 retracts, the male clamp 11 enters the inside of the clamping slot 6, and is positioned by the clamping tongue 5.

[0045] The present invention also provides a firefighting and rescue method for underwater emergency disaster reduction, specifically:

[0046] The rescue technicians put the equipment into the distressed river and operate the air pump to quickly inflate the dam bag at the bottom of the equipment to ensure that the pressure inside the dam bag is stable and the equipment meets the requirements of the load floating stably on the water surface. Then, the remote control system is used to operate multiple rescue equipment to move to the upstream of the embankment where the breach is located;

[0047] For the rescue of people who fall into the water, according to actual needs, single or multiple rescue equipment can be spliced ​​to go to the disaster area to rescue the people who fall into the water; splicing multiple rescue equipment can increase the number of people rescued at a time and improve the rescue efficiency;

[0048] For the rescue of the breach, after reaching the upstream, three emergency rescue equipment will be moved to the upstream of the breach near the embankment, and the rescue equipment will be connected in pairs by ropes and other common binding equipment, fixed to the edge of the embankment slope, and other impact-connected inflatable embankment emergency rescue equipment will be operated to achieve connection through impact; finally, a stable emergency rescue operation platform will be formed in the upstream area of ​​the breach, and the assembly form is as follows: Figure 5 As shown;

[0049] The connecting column 14 is operated to rise to a specified height, and the rolling belt devices 15 are connected to each other by rotating the connecting column 14, so as to form multiple material transportation channels. Figure 5 As shown, in this embodiment, a trapezoidal working platform is formed to surround the breach; and 6 feeding ports are connected at the center of the working platform.

[0050] On the downstream side of the breach, a rescue operation platform can be formed in the same way. Rescue workers deliver disaster relief materials to the initial end of the belt, and the relief materials are transported to the upstream side of the breach through the belt conveyor and delivered into the water body. When the volume of rescue materials delivered in a short period of time is sufficient, the breach will gradually be blocked and closed over time. When the breach basically blocks the water flow, rescue officers and soldiers are organized to quickly block the breach position, ultimately achieving efficient, rapid, and unmanned modern flood prevention and rescue work.
