Description

Technical Field

[0001] The invention belongs to the technical field of emergency fire rescue facilities, and in particular relates to an emergency fire extinguishing device. Background Art

[0002] Firefighting solutions for industrial and everyday life have a growing variety of firefighting equipment and are becoming increasingly mature. However, most firefighting solutions require the use of fire trucks and other equipment. For example, high-rise building fires require high-lift fire trucks, while warehouses and small buildings primarily rely on tank fire trucks. While these firefighting solutions are effective, the time required from the moment a fire occurs to the arrival of the equipment and its deployment on-site until it meets operational standards is significant. For emergency rescue, time is of the essence. Generally, the sooner a fire is controlled, the shorter the extinguishing time and the higher the efficiency, which can prevent the spread of the fire and effectively minimize losses. In particular, with the increasing number of electric vehicles and battery-powered vehicles in recent years, these battery-powered vehicles can spontaneously ignite and ignite rapidly after a short circuit or collision. If fires are not effectively controlled immediately, they can lead to secondary hazards. Therefore, it is necessary to research suitable firefighting devices to quickly and conveniently carry out rescue operations and promptly control fires, thereby preventing the spread of fire and reducing secondary disasters. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes an emergency fire extinguishing device.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] An emergency fire extinguishing device includes a fire blanket body with an operating port. The fire blanket body includes an outer sheet and an inner sheet, which form a functional cavity at their edges. A plurality of channels communicating with the functional cavity are provided between the outer sheet and the inner sheet, each channel communicating with a liquid inlet provided on the outer sheet. A plug is detachably mounted on the operating port.

[0006] The outer piece is provided with an outer skirt at a position corresponding to the functional cavity, and the inner piece is provided with an inner skirt at a position corresponding to the functional cavity. The outer skirt includes a plurality of independent outer pieces, and adjacent two outer pieces are connected by an outer flexible connection portion. The inner skirt includes a plurality of independent inner pieces, and adjacent two inner pieces are connected by an inner flexible connection portion, and the inner flexible connection portion corresponds to the outer flexible connection portion one by one.

[0007] A counterweight is provided at the bottom of the functional cavity, and a flexible extension portion is provided at the lower part of the inner edge piece. The deformation direction of the flexible extension portion is stretching from the center of the fire blanket body to the edge. The deformation direction of the inner flexible connection portion and the outer flexible connection portion is stretching along the edge of the fire blanket body perpendicular to the deformation direction of the flexible extension portion.

[0008] Furthermore, each outer edge piece and each outer flexible connecting portion is an integrally formed structure, each inner edge piece and each inner flexible connecting portion is an integrally formed structure, the functional cavity is formed between the outer skirt and the inner skirt, and the main part of the outer piece and the main part of the inner piece are bonded or sewn to ensure the stability of the inner and outer layer structures of the fire blanket body.

[0009] Furthermore, a plurality of lifting rings are symmetrically provided on the outer plate, and a lifting rope is tied to the lifting rings.

[0010] Furthermore, the lifting ring is arranged on the main part of the outer piece near the outer skirt.

[0011] Furthermore, there are 3-5 lifting rings arranged.

[0012] Furthermore, the counterweight is in an arc-shaped structure that bends toward the outside of the fire blanket body.

[0013] Furthermore, the channels are evenly distributed around the center of the fire blanket body.

[0014] Furthermore, there are 8-20 channels.

[0015] The following provides a fire extinguishing method using the above device, comprising the following steps:

[0016] S1. Place the fire blanket with the inner sheet facing downward directly over the fire source. The counterweight, under its own weight, causes the edge of the fire blanket to touch the ground, and the inner and outer flexible connectors to deform adaptively to the undulations of the ground, ensuring that the fire blanket completely covers the burning object.

[0017] S2. Inject a counterweight liquid into the liquid inlet. After the counterweight liquid flows into the functional cavity along the channel, the flexible extension portion is completely in contact with the ground, ensuring that the fire blanket body isolates the burning object from the outside world, cuts off the contact between the fire source and the outside air, and prevents the fire from spreading.

[0018] S3. Use the operating port to spray the fire extinguishing agent under the fire blanket to achieve fire extinguishing operations in the enclosed space;

[0019] S4. After the fire is extinguished, remove the fire blanket directly.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The invention has a reasonable structural design, low operation difficulty, and excellent use effect. It can be used as a professional firefighting tool for fire brigades or as a regular firefighting equipment for families or social institutions. The fire blanket body completely covers the burning object, cutting off the contact between the fire source and the outside air. Since the fire blanket body isolates the burning object from the outside world, preventing the fire from spreading, it also isolates oxygen to the greatest extent, which is conducive to fire control and prevents re-ignition.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] An emergency fire extinguishing device, such as Figures 1 to 9 As shown, it includes a fire blanket body 2 provided with an operating port 1, and all components of the fire blanket body are made of fireproof materials (such as glass fiber fireproof cloth, fireproof silicone cloth or fireproof plastic coated cloth, etc.). The selection of fireproof materials is well known in the prior art and will not be repeated here. The fire blanket body includes an outer sheet 3 and an inner sheet 4, which form a functional cavity 5 at the edge; a number of channels 6 connected to the functional cavity are provided between the outer sheet and the inner sheet, and each channel is connected to a liquid inlet 7, which is provided on the outer sheet to ensure the integrity of the inner sheet and better fireproofing. It should be noted that the operating port and the liquid inlet do not have to be arranged in the center of the main part of the fire blanket body, and can be arranged near the middle of the main part of the fire blanket body according to actual conditions.

[0037] Typically, the channels are evenly distributed around the center of the fire blanket body. There are 8 to 20 channels. A plug is detachably installed on the operating port. When the operating port needs to be used, the plug can be removed. In a further improved solution, a one-way valve can be installed on the operating port to allow the fire extinguishing agent to be injected inward without the fire source overflowing, which is highly safe and has a good use effect. It should be pointed out that the reason why the functional cavity is designed as a closed smaller cavity at the edge of the fire blanket body, rather than being directly open to the main structure of the inner and outer sheets, is mainly to ensure that the balancing liquid 18 entering the liquid inlet can be quickly filled into the functional cavity, and the balancing liquid flows adaptively inside the functional cavity according to the terrain, can reach balance more quickly, and rely on gravity to compact the flexible extension part, so that the edge of the fire blanket body fits the ground, effectively solving the problem of poor fit between ordinary fire blankets and the ground and low operating efficiency during use.

[0038] An outer skirt is provided at the position of the outer piece corresponding to the functional cavity, and an inner skirt is provided at the position of the inner piece corresponding to the functional cavity. The outer skirt includes several independent outer pieces 8, and adjacent two outer pieces are connected by an outer flexible connection part 9. The inner skirt includes several independent inner pieces 13, and adjacent two inner pieces are connected by an inner flexible connection part 14. The inner flexible connection part corresponds to the outer flexible connection part one by one, which is more conducive to the coordinated deformation of the inner skirt and the outer skirt, better adapting to changes in terrain and improving the fit between the fire blanket body and the ground.

[0039] A counterweight 10 is provided at the bottom of the functional cavity, and a flexible extension 11 is provided at the lower portion of the inner edge sheet. The flexible extension 11 deforms from the center of the fire blanket body toward the edge. The inner and outer flexible connectors deform along the edge of the fire blanket body, perpendicular to the direction of deformation of the flexible extension. For example, the flexible extension and the flexible connector can both be made into pleated structures, with deformation achieved through pleated stretching. Therefore, the flexible extension, flexible connector, outer sheet body, inner sheet body, outer edge sheet, and inner edge sheet can be integrally formed from the same material, requiring only indentations or creases to be made in the flexible extension and connector.

[0040] Each outer edge piece and each outer flexible connecting portion is an integrally formed structure, and each inner edge piece and each inner flexible connecting portion is an integrally formed structure. That is, a functional cavity is formed between the outer skirt and the inner skirt. The main portion of the outer piece and the main portion of the inner piece are bonded or sewn together to ensure the stability of the inner and outer layer structures of the fire blanket body.

[0041] In an optional embodiment, several lifting rings are symmetrically provided on the outer piece, and a lifting rope 12 is tied to the lifting ring. The fire blanket body can be lifted by the lifting rope with the help of a drone or other external tools, so that the fire extinguishing device can be directly placed on the fire object, with little limitation in use and higher safety. Preferably, the lifting ring is arranged on the main part of the outer piece near the outer skirt. When the fire blanket body is lifted, the overall stability is good and the shape of the skirt is not affected. Usually, 3-5 lifting rings are arranged. For example, when the fire blanket body is rectangular or square, the lifting rings are respectively arranged at the four corners of the fire blanket body, and lifting ropes are respectively provided on the lifting rings at the four corners of the fire blanket body.

[0042] The aforementioned counterweight features an arc-shaped structure that curves outward from the fire blanket body. This ensures that, under the influence of its own weight, the edge of the fire blanket body can touch the ground and maintain stability, meeting basic firefighting requirements. Even if the edge of the fire blanket body does not fully contact the ground, for more demanding firefighting requirements, counterweight liquid can be injected through the channel. The counterweight liquid flowing into the functional cavity will deform the flexible extension section and make it conform to the ground.

[0043] It should be noted that the weighting liquid can be water or a fluid fire extinguishing agent or other non-combustible liquid that can flow smoothly into the functional cavity. Of course, the weighting liquid can also be poured before the fire blanket body is laid on the fire. Since the functional cavity is a connected cavity, it can adaptively flow after the fire blanket body is laid on the fire, and play a very good weighting effect, so that the flexible extension part can be deformed and stably fit the ground, so that the fire blanket body and the ground are better sealed. In addition, the flexible connection part can be adaptively deformed, that is, the inner edge piece and / or the outer edge piece can change the distance and angle between each other, and the edge part of the fire blanket body can adaptively change shape according to the terrain around the fire, ensuring that the fire blanket body and the surface around the fire are reliably fitted, thereby making the interior of the fire blanket body approximately closed, which is more conducive to fire extinguishing.

[0044] In an optional embodiment, if Figure 4As shown, the length of the inner flexible connection part (extending along the edge of the fire blanket body toward the center of the fire blanket body) is smaller than the length of the outer flexible connection part (extending along the edge of the fire blanket body toward the center of the fire blanket body). Generally, the inner flexible connection part is 1 / 2-4 / 5 of the length of the outer flexible connection part, and the flexible extension part is designed at the connection position between the inner flexible connection part and the inner sheet main body part 19. With such a structural design, the inner and outer flexible connection parts and the flexible extension part cooperate with each other. That is to say, even if the edge of the fire blanket body is not fully in contact with the ground during the laying of the fire blanket body, then after the balancing liquid is injected, when a certain part (such as the flexible extension part) is deformed, it will also drive the other parts (inner flexible connection part, outer flexible connection part) to deform adaptively, which can bring about better performance, ensure the stable fit between the edge of the fire blanket body and the ground, and isolate the outer diameter air to the maximum extent.

[0045] A fire extinguishing method using the above device comprises the following steps:

[0046] S1. Place the fire blanket with the inner sheet facing downward directly over the fire source. The counterweight, under its own weight, causes the edge of the fire blanket to touch the ground, and the inner and outer flexible connectors to deform adaptively to the undulations of the ground, ensuring that the fire blanket completely covers the burning object.

[0047] S2. Inject a weighted liquid into the liquid inlet. After the weighted liquid flows into the functional cavity along the channel, the flexible extension portion is completely in contact with the ground, ensuring that the fire blanket body isolates the burning object from the outside world, cuts off the contact between the fire source and the outside air, prevents the fire from spreading, and isolates oxygen to the greatest extent, making it easier to extinguish the fire and prevent it from re-igniting.

[0048] S3. Use the operating port to spray the fire extinguishing agent under the fire blanket to achieve fire extinguishing operations in the enclosed space;

[0049] S4. After the fire is extinguished, remove the fire blanket directly.

[0050] In an optional embodiment, the inner surface of the inner sheet is provided with a plurality of active fire extinguishing components. Specifically, a plurality of independent storage bags 15 are provided on the inner surface of the inner sheet, and an outer bag body 16 is wrapped around the outside of each storage bag. The storage bag is filled with explosive gas, and the outer bag body is filled with fire extinguishing medium. The storage bag and the outer bag body are both made of fragile and non-fireproof materials. When the flame contacts the outer bag body, the outer bag body and the storage bag quickly rupture, and the explosive gas in the storage bag produces a slight explosion, splashing the fire extinguishing medium in the outer bag body. For example, the amount of fire extinguishing medium filled is 1 / 8-1 / 4 of the total volume of the cavity between the outer bag body and the storage bag, and the amount of explosive gas filled in the storage bag does not exceed 15ml. The fire extinguishing medium is made of dry powder, fine sand or sand, and the explosive gas is made of hydrogen or carbon monoxide. Such a design can ensure that the impact generated by the explosion of the explosive gas in the storage bag has a good effect of "blowing out" the flame. At the same time, the fire extinguishing medium will also have an impact on the flame at the moment of explosion to achieve the effect of extinguishing the flame. Combined with the ability of the fire blanket body to isolate the external environment, this fire extinguishing device has better fire extinguishing ability. Common fires in daily life can be effectively controlled or even completely extinguished by using this fire extinguishing device without additional fire extinguishing facilities.

[0051] In a further improved solution, Figure 7 and Figure 8 As shown, the storage bag and the outer bag body are both made of stretchable flexible materials or flexible structures (such as similar to flexible extension parts), and a counterweight ball 17 is provided in the storage bag. When the fire blanket body is laid, the counterweight ball stretches the storage bag due to its own weight, causing the counterweight ball to suspend. The fire extinguishing medium in the outer bag body is closer to the fire source, which not only makes it easier to trigger the explosive gas in the storage bag to produce a slight explosion, but also, the fire extinguishing medium is closer to the fire source, and the fire extinguishing medium is better dispersed on the surface or even the inside of the burning object. When the storage bag explodes, the splashing fire extinguishing medium produces a better fire extinguishing effect.

[0052] The invention has a reasonable structural design, low operation difficulty, and excellent use effect. It can be used as a professional firefighting tool for fire brigades or as a regular firefighting equipment for families or social institutions. The fire blanket body completely covers the burning object, cutting off the contact between the fire source and the outside air. Since the fire blanket body isolates the burning object from the outside world, preventing the fire from spreading, it also isolates oxygen to the greatest extent, which is conducive to fire control and prevents re-ignition.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
