[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fire blanket that incorporates a pressure relief mechanism located at a pressure relief port. This mechanism is movable relative to the pressure relief port to close or open it, thus addressing the problem in the prior art where, when fire blankets are used to extinguish fires, smoke tends to accumulate within the area covered by the blanket, potentially leading to secondary accidents such as explosions.

Detailed Implementation
[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0040] In the current firefighting field, fire blankets are typically placed over objects after they catch fire to prevent the fire from spreading. However, when the objects are electric vehicles, electric aircraft, or electric drones, the battery packs undergo continuous chemical reactions and thermal runaway, making the fire extinguishing time different from that of conventional objects. Especially with the frequent safety accidents involving new energy vehicles, using conventional fire blankets can cause a rapid increase in pressure within the blanket due to the large amount of gas generated by thermal runaway. The blanket cannot quickly depressurize to prevent an explosion caused by excessive pressure, thus failing to provide sustained suffocation and prevent reignition. The safety performance of traditional fire blankets needs improvement. It should be noted that the fire blanket described in this application is not only applicable to electrical equipment using new energy batteries but also to firefighting and rescue operations involving other types of fire-related objects.
[0041] refer to Figure 1-11The present solution provides a fire blanket 100, which includes a blanket body 1, a pressure relief port 11 that penetrates the blanket body 1, and a pressure relief mechanism 2, which is disposed at the pressure relief port 11 and can move movably relative to the pressure relief port 11 to close or open the pressure relief port 11. Understandably, in the existing technology, when the fire blanket 100 is used for fire extinguishing, it is placed over the object to prevent the fire from spreading further. However, if the fire blanket 100 is placed over the object before the fire is completely extinguished, smoke will accumulate and the air pressure inside the fire blanket 100 will increase, which may easily lead to secondary accidents or even explosions. This solution provides a pressure relief port 11 on the fire blanket 100 and a pressure relief mechanism 2 at the pressure relief port. The pressure relief mechanism 2 can move relative to the blanket body 1 to close or open the pressure relief port 11, thereby releasing the air pressure inside the fire blanket 100 in a targeted manner to reduce the concentration of smoke accumulation and prevent secondary accidents such as explosions.
[0042] It should be noted that the pressure relief mechanism 2 is made of high-temperature resistant and fireproof material, which can be inorganic compound material or polymer material, etc., and there is no specific limitation.
[0043] In some embodiments, at least a portion of the pressure relief mechanism 2 is fixedly connected to the blanket body 1, and the pressure relief mechanism 2 is configured to open or close the pressure relief port 11 under a preset pressure. Typically, the fire blanket 100 needs to be depressurized at smoke accumulation points. The preset opening pressure of the pressure relief mechanism 2 can be such that the safety pressure relief mechanism 2 opens when the pressure inside the fire blanket 100 exceeds a certain pressure value (e.g., 0.3MPa, 0.5MPa, 0.7MPa, 1MPa, etc., specifically designed according to the actual fire conditions of the fire-fighting equipment), and closes when the pressure falls below a certain value (e.g., 0.3MPa, 0.5MPa, 0.7MPa, 1MPa, etc., specifically designed according to the actual fire conditions of the fire-fighting equipment). This effectively ensures the continuous suffocation effect on the accident object. Specifically, this applies to fire extinguishing of new energy vehicles and relatively enclosed and narrow spaces such as roll-on / roll-off ships.
[0044] It should be noted that at least part of the pressure relief mechanism 2 is fixedly connected to the blanket body 1 using high-temperature resistant and fireproof materials, which can effectively prevent the connection from cracking in the event of an accident.
[0045] Specifically, the way in which at least a part of the pressure relief mechanism 2 is fixedly connected to the blanket body 1 can be an integral connection or a detachable fixed connection, or it can be an embedded connection; preferably, an embedded connection is adopted, in which the pressure relief mechanism 2 and the fire blanket 100 are embeddedly connected to effectively ensure the sealing of the connection. That is, the pressure relief mechanism 2 is embedded in the blanket body 1 of the fire blanket 100 and is set at the pressure relief port 11, which can ensure that the pressure relief port 11 can be effectively opened to relieve pressure when the internal pressure of the fire blanket 100 is working, without the possibility of premature pressure relief due to poor sealing performance between the pressure relief mechanism 2 and the blanket body 1.
[0046] refer to Figure 2-4 and Figure 7-10 The fire blanket 100 has a blanket body 1 including a first side 12 and a second side 13 arranged opposite to each other. The pressure relief mechanism 2 passes through the blanket body 1 and is disposed in the pressure relief port 11. The second side 13 is the side that covers the fire-fighting object, and the first side 12 is the other side that does not cover the fire-fighting object. When a large amount of smoke accumulates in the fire blanket 100, the pressure relief mechanism 2 opens in the direction of the first side outward to release the pressure in the fire blanket 100.
[0047] In some embodiments, a plurality of pressure relief ports 11 are provided on the blanket body 1. The plurality of pressure relief ports 11 are spaced apart on the blanket body 1. They can be arranged at equal intervals, or the number of pressure relief ports 11 can be set according to the actual use scenario and needs. At the same time, a plurality of pressure relief mechanisms 2 are also provided. The plurality of pressure relief mechanisms 2 are arranged one-to-one with the pressure relief ports 11 to achieve pressure relief at multiple locations. This effectively relieves the pressure of the smoke accumulated at high pressure locations when the fire blanket 100 is placed on the accident object and there are different internal pressures at different locations.
[0048] In some embodiments, the material of the blanket body 1 of the fire blanket 100 may include at least one of glass fiber, ceramic fiber, and silicone. It should be noted that the material of the blanket body 1 may be the same as the material of the pressure relief mechanism 2, so that the two can be better fitted together during processing.
[0049] In some embodiments, the shape of the pressure relief port 11 includes at least one of a circle, an ellipse, and a regular polygon. It should be noted that the shape of the pressure relief port 11 is not specifically limited; as a channel for pressure release, it only needs to be easy to manufacture. In particular, the shape of the pressure relief port 11 is generally adapted to the pressure relief mechanism 2 to facilitate a better connection between the two.
[0050] In some embodiments, the thickness of the fire blanket 100 is 0.5mm to 1.2mm; and / or, the height of the pressure relief mechanism 2 relative to the blanket body 1 is 3mm to 30mm. It should be noted that the thickness of the fire blanket 100 should not be too thick, to ensure that the weight of the fire blanket 100 is moderate, facilitating firefighters to carry out firefighting operations more easily; and the pressure relief mechanism 2 should release pressure outwards towards the first surface 12, such as... Figure 2 The pressure relief mechanism shown is set at a certain height relative to the blanket body 1 for better processing and installation. The height of the pressure relief mechanism 2 relative to the blanket body 1 is 3mm~30mm, which refers to the static height of the pressure relief mechanism 2 when it is not in operation. At the same time, the fire blanket 100 is also suitable for use on roll-on / roll-off ships transporting new energy vehicles. It should be able to operate in relatively narrow spaces, and the height of the pressure relief mechanism 2 should not be too high. The specific thickness of the fire blanket 100 and the height of the pressure relief mechanism 2 relative to the blanket body 1 can be designed according to actual needs.
[0051] Example 1
[0052] like Figure 2-6 As shown, in some embodiments, the pressure relief mechanism 2 includes: a mounting base 23, a pressure relief cover 21, and a telescopic member 22. The mounting base 23 is disposed at the pressure relief port 11 and connected to the blanket body 1. The pressure relief cover 21 is used to cover the mounting base 23 to cover the pressure relief port 11. One end of the telescopic member 22 is connected to the mounting base 23, and the other end of the telescopic member 22 is connected to the pressure relief cover 21 to realize the closure or opening of the pressure relief port 11 by the pressure relief cover 21.
[0053] Specifically, the pressure relief mechanism 2 is integrally fixedly connected to the blanket body 1 of the fire blanket 100 via the mounting base 23. The mounting base 23 is installed at the pressure relief port, and a pressure relief cover 21 is provided on the mounting base 23 facing the first surface 12. A telescopic member 22 is provided inside the mounting base 23. One end of the telescopic member 22 is connected to the pressure relief cover 21, and the other end of the telescopic member 22 is connected to the mounting base. The pressure relief cover 21 and the mounting base 23 are connected by the telescopic member 22, thereby achieving the sealing of the pressure relief port. It can be understood that when high-pressure smoke accumulates in the fire blanket 100, the high-pressure smoke opens the pressure relief cover 21 through the pressure relief port 11. When the pressure decreases, the pressure relief cover 21 closes.
[0054] In some embodiments, the mounting base 23 is provided with a pressure relief channel 236, which is connected to the pressure relief port 11. It can be understood that the mounting base 23 and the pressure relief port 11 together define the pressure relief channel 236, and the pressure relief cover 21 covering the mounting base 23 is equivalent to the pressure relief port 21 covering the pressure relief channel 236.
[0055] In some embodiments, the mounting base 23 includes: a receiving body 231, a first connecting portion 232 and a second connecting portion 234, wherein the receiving body 231 encloses and defines a receiving cavity; the first connecting portion 232 is connected to the receiving body 231; the second connecting portion 234 is connected to the first connecting portion 232 via a third connecting portion 235, and a connection port 233 is defined between the first connecting portion 232 and the second connecting portion 234; wherein the connection port 233 is used to connect to the blanket body 1.
[0056] Specifically, such as Figure 5-6 As shown, the mounting base 23 is provided with a receiving body 231, a first connecting part 232, a third connecting part 235 and a second connecting part 234 in sequence from top to bottom. The middle of these four parts defines a pressure relief channel 236. A connection port 233 is defined between the first connecting part 232, the third connecting part 235 and the second connecting part 234. The connection port 233 is used to connect with the blanket body 1. Specifically, the cross-section of the connection port 233 can be a groove structure. The blanket body 1 is connected in the groove structure to achieve a fixed connection with the pressure relief mechanism 2.
[0057] In some embodiments, the shape of the third connecting portion 235 of the mounting base 23 is adapted to the shape of the pressure relief port 11. It is understood that the connecting port 233 is sleeved on the pressure relief port 11 and fixedly connected to the blanket body 1, thereby fixing the mounting base 2311. Specific fixed connection methods include, but are not limited to, interlocking connection, braided connection, etc.
[0058] In some embodiments, the receiving body 231 encloses and defines a receiving cavity, which communicates with the pressure relief port 11. The receiving cavity has an opening, and a pressure relief cover 21 covers the opening. A mounting portion 2311 is provided at the bottom of the receiving cavity for connecting to the telescopic member 22. The receiving cavity is used to accommodate the telescopic member 22. Specifically, the mounting portion 2311, which serves as part of the pressure relief channel 236 within the receiving cavity, has a stepped structure at its bottom. The upper surface of the mounting portion 2311 is used to connect to the telescopic member 22, and the receiving cavity is used to accommodate the telescopic member 22.
[0059] In some embodiments, the telescopic member 22 includes a spring. Specifically, one end of the spring connects to the pressure relief cover 21, and the other end connects to the mounting portion 2311 of the mounting base 23. Specifically, the pressure relief cover 21 can be a circular, elliptical, or polygonal structure. The pressure relief cover 21 effectively seals the opening of the receiving cavity. The spring's initial state within the receiving cavity can be either a stretched state or a free state (designed according to the specific pressure relief capacity). Figure 3As shown, when the pressure inside the fire blanket 100 accumulates, the pressure relief cover 21 is forced open by the pressure, thereby relieving the pressure accumulated inside the fire blanket 100. After the pressure inside the fire blanket 100 is released, the pressure relief cover 21 is pulled back under the action of the spring, thereby closing the opening of the receiving cavity.
[0060] In other embodiments, the telescopic member 22 includes a telescopic structure such as a tension spring or torsion spring that stores capacity and releases it under certain conditions; the specific type is not limited.
[0061] Example 2
[0062] In some other alternative embodiments, such as Figure 7-10 As shown, the pressure relief mechanism 2 includes a fire extinguishing patch, which covers the pressure relief port 11. A portion of the fire extinguishing patch is fixedly connected to the blanket body 1, while another portion is adhesively connected to the blanket body 1. It can be understood that the pressure relief mechanism 2 is a semi-enclosed structure; one part is fixedly connected to the blanket body 1, while the other part is adhesively connected to the blanket body 1. Specifically, the pressure relief mechanism 2 includes a Velcro strap connected to the fire extinguishing patch. When high-pressure smoke accumulates inside the fire blanket 100, the Velcro strap attached to the fire extinguishing patch, which is then opened by the expansion of the high-pressure gas inside the fire blanket 100, thus achieving pressure relief.
[0063] In some embodiments, the pressure relief mechanism 2 is a semi-enclosed structure, and the fire extinguishing patch is designed as a polygonal structure, such as a quadrilateral structure. Two opposite sides of the fire extinguishing patch are fixedly connected to the fire blanket 100, and the other two opposite sides of the fire extinguishing patch are bonded to the blanket body 1 by means of high-temperature resistant Velcro. The fire extinguishing patch covers the pressure relief port 11, which can be the first surface 12 of the blanket body 1. When the pressure inside the fire blanket 100 accumulates, the Velcro edge is expanded and opened, thereby achieving the effect of pressure relief. When the pressure decreases to a certain value, the Velcro is bonded to the blanket body 1 of the fire blanket 100, forming a relatively suffocating environment, thereby achieving the effect of preventing reignition.
[0064] Example 3
[0065] In some embodiments, a fire-fighting device 300 is provided, such as Figure 11 As shown, the fire-fighting device 300 includes a fire blanket 100; specifically, the fire blanket 100 is part of the fire-fighting device 300, which also includes a traction mechanism (not shown in the figure). The traction mechanism is connected to the fire blanket 100 and is used to store the fire blanket after the fire is extinguished.
[0066] In other embodiments, the fire-fighting device 300 also includes a fire extinguishing agent, which works together with the fire blanket 100 to achieve better fire extinguishing of objects involved in fire accidents.
[0067] In summary, by integrating a pressure relief mechanism 2 into the existing fire blanket, the air pressure inside the fire blanket 100 is released in a targeted manner to reduce the concentration of smoke accumulation, thereby preventing secondary accidents such as explosions. This greatly improves the stability and safety of the fire blanket 100 operation and enhances its performance.
