Description

Technical Field

[0001] The invention relates to the technical field of escape devices, and in particular to an emergency escape device for personnel in response to dam-breaking floods. Background Art

[0002] Reservoirs are at risk of dam breaching in extreme environments such as earthquakes and heavy rainfall. Dam breach floods are short-lived and have strong impact, posing a great threat to densely populated areas such as villages, markets, and cities along the way, and seriously endangering the lives of the people. When a dam breach disaster occurs, although a certain degree of risk avoidance can be achieved by using an early warning system to send emergency notifications to the downstream, due to the extremely fast spread of floods, many people are still unable to evacuate in time even with early warnings, and face huge risks to their lives. Traditional flood control facilities, such as life-saving platforms, are often unable to effectively respond to the climbing effect of floods due to the extremely short avoidance time and limited platform height, and it is difficult to fully protect the lives of the people. Therefore, it is crucial to obtain an emergency risk avoidance device for dam breach floods with functions such as rapid deployment, impact resistance, and waterproofing.

[0003] The existing patent document CN115162817A discloses an underground temporary shelter system for defending against short-duration strong impacts of ground fluids, which includes an underground shelter room with emergency rescue supplies and shelter and escape exits, allowing people within the service radius to temporarily avoid dam-break flood disasters. However, this technology and most existing shelter devices require the shelter personnel to know the location of the shelter device and go to the shelter on their own. It still requires early warning to reserve evacuation time, and the personnel going to the shelter often need to overcome problems such as traffic jams on the way. It is difficult to deal with flood dam-break disasters that spread very quickly and cannot be warned in time or cleared by roads. Summary of the invention

[0004] In view of the defects of the prior art, the purpose of the present invention is to propose a new emergency evacuation device for personnel to deal with dam break floods. The device can be quickly deployed in a variety of flexible deployment methods and can be placed outdoors or inside buildings. There is no need for personnel to go to the shelter on their own.

[0024] The present invention is described in detail below in conjunction with the embodiments and drawings, but it should be understood that the embodiments and drawings are only used to exemplify the present invention and do not constitute any limitation on the protection scope of the present invention. All reasonable changes and combinations within the scope of the inventive concept of the present invention fall within the protection scope of the present invention.

[0025] See attached Figure 1-2According to the technical solution of the present invention, in some specific embodiments, the emergency escape device for personnel in response to dam-breaking floods of the present invention is spherical as a whole, including an outer structure, an inner structure and a connection structure connecting the outer structure and the inner structure, wherein the outer structure includes: a hollow outer sphere 1-1, a traction and fixing assembly located on the surface of the outer sphere 1-1, such as a plurality of hooks 1-3 fixed on the surface of the outer sphere 1-1 and a traction rope 1-2 connected to the hook 1-3, and a sliding sealing door entering the outer sphere 1-1, namely, an outer sliding sealing door 1-4; an inner The structure includes: a hollow inner sphere 3-1, living and safety facilities such as personnel seats 3-2 and emergency supplies 3-3 arranged in the inner sphere 3-1, and a sliding sealed door for entering the inner sphere 3-1, namely the inner sliding sealed door 3-4; the connection structure includes: a number of shock-absorbing springs evenly distributed between the outer sphere 1-1 and the inner sphere 3-1 and with both ends fixed to the inner surface of the outer sphere 1-1 and the outer surface of the inner sphere respectively, and a number of spherical counterweights such as solid iron balls 2-2 that are limited between the outer sphere 1-1 and the inner sphere 3-1 and can slide freely.

[0026] Through the above emergency evacuation device of the present invention, when a dam burst flood comes, the evacuees can open the sliding sealing door of the outer sphere and the sliding sealing door of the inner sphere in sequence, enter the inner sphere and close all the sealing doors in sequence, then find the oxygen supply equipment among the emergency supplies and open it, and finally, with the help of safety equipment, such as sitting on the personnel seat 3-2 equipped with a safety belt, wait for the dam burst flood to stop and for rescue workers to rescue them.

[0027] The emergency escape device can be fixed or towed by means of a traction fixing assembly such as a hook and a traction rope on the outer sphere, such as fixing the other end of the traction rope not connected to the hook on a building or open space, or when the emergency escape device is not fixed, the emergency escape device can be towed to a safe place by means of the other end of the traction rope.

[0028] The connection structure of the emergency shelter has both adaptive shock absorption and buffering effects, wherein the shock absorbing spring can be used to absorb the impact of the flood on the emergency shelter and reduce the shock. When the emergency shelter is impacted by a flood or collides with an obstacle and tilts, the spherical counterweight can automatically slide to a lower position due to its own gravity, and maintain the center of gravity of the entire emergency shelter, especially its inner structure, at a lower position. That is, it can maintain the center of gravity of the shelter at a lower position through the principle of center of gravity stability, so that when the emergency shelter is subjected to external force (such as flood water impact), the center of gravity of the shelter will automatically return to the lowest point, so that the device can be restored to an upright position, protecting the people taking shelter inside the device from the impact of the flood water.

[0029] In order to improve the space utilization rate of the emergency shelter, the emergency supplies 3-3 such as medicines, food, warm clothes, etc. in the inner sphere 3-1 can be arranged in the gap between the seats 3-2.

[0030] Furthermore, the personnel seat includes a safety belt to reduce the harm caused by collision.

[0031] Furthermore, a solid iron counterweight may be provided under the seat to maintain a stable center of gravity.

[0032] Furthermore, the spaces between the seats are used to store emergency supplies, such as medicines, food, warm clothing, etc.

[0033] In some preferred embodiments, the spherical counterweight is disposed in a limiting groove, and the limiting groove is opened on the inner surface of the outer sphere 1-1 and is recessed outward and / or on the outer surface of the inner sphere 3-1 and is recessed inward.

[0034] In some preferred embodiments, the outer sphere 1-1 includes three material layers, namely a transparent silicone layer on the outer surface, a polyurethane transparent coating on the inner surface, and a polycarbonate layer therebetween.

[0035] In some preferred embodiments, the inner sphere 3-1 includes three material layers, namely a transparent silicone layer on the inner surface, a polyurethane transparent coating on the outer surface, and a polycarbonate layer therebetween.

[0036] In the above two preferred embodiments, the outer sphere 1-1 and the inner sphere 3-1 are both designed with multi-layer protective materials, which are mainly polycarbonate, and are added with transparent silicone material that can absorb impact, and polyurethane transparent coating that improves wear resistance and impact resistance. Under the above material structure, the outer sphere 1-1 and the inner sphere 3-1 are almost transparent, which is convenient for rescue personnel to detect the evacuees and / or observe the status of the evacuees and carry out rescue.

[0037] Example 1

[0038] The emergency escape device of the present invention is set in a depression of a building or an outdoor space to simulate the situation that when a dam-breaking flood is about to come, the escapers enter the emergency escape device as follows:

[0039] Assume that the weight of the emergency evacuee is W h 60kg, additional total weight (weight of other facilities of emergency escape device except the mass of sphere material) W o 50kg;

[0040] The radius of the outer sphere R outer =1m, the material thickness of the outer sphere is t outer =0.05m, inner radius of the outer sphere router =0.95m, the radius of the inner sphere R inner =0.8m, the material thickness of the inner sphere is t inner =0.05m, inner radius of the inner sphere r inner =0.75m; then the volume of the outer sphere Outer sphere material volume Volume of inner sphere material Polycarbonate material density ρ pc =1200kg / m 3 , then the weight of polycarbonate material W pc =ρ pc (V outer +V inner )=1193kg, therefore, the unloaded weight of the device is W total =W pc +W o =1243kg, device no-load gravity F weight =W total g = 12181.4N;

[0041] The density of water is ρ water =1000kg / m 3 , gravitational acceleration g = 9.81 m / S 2 Calculate the buoyancy when half of the shelter is submerged in water.

[0042] Then the device surplus weight F = F buoyancy -F weight =8362N, then the maximum number of people that can be sheltered in the device is Considering the oxygen reserve and volume of the device, it is recommended that m=2.

[0043] Example 2

[0044] Based on Example 1, the impact of the flood on the device when the dam-breaking flood is about to come is simulated as follows:

[0045] (1) General:

[0046] Flood velocity V = 5m / s;

[0047] Outer sphere surface area

[0048] The flood impact force

[0049] Flood Pressure

[0050] Impact strength of polycarbonate material Ppc =70000000N / m 2 , P impact< P pc ,Therefore, the device can effectively resist the impact of floods.

[0051] (2) Extreme situation: (only the outer surface of the device is directly impacted by the flood, and the flood flow rate is much higher than the normal situation)

[0052] Flood velocity V = 100 m / s;

[0053] Outer sphere positive surface area

[0054] The flood impact force

[0055] Flood Pressure

[0056] Impact strength of polycarbonate material P pc =70000000N / m 2 , P impact< P pc , so in extreme cases, the device can still effectively resist the impact of floods.

[0057] The above embodiments are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
