Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a water-filled automotive flame-retardant fire control blanket. Background Technology

[0002] In automotive fires, the confined interior space, highly flammable fuel, and rapid fire spread make firefighting and control extremely challenging. In the initial stages of a fire, rapid and effective fire control measures are crucial to preventing the accident from escalating. In recent years, fire blankets, as portable, non-electric emergency fire extinguishing devices, have been widely used in scenarios such as thermal runaway of new energy vehicle batteries and fires in small gasoline vehicles. They are typically made of high-temperature resistant, flame-retardant fiber materials and are manually applied to the battery pack, engine compartment, or other areas on fire in the vehicle. Their physical barrier function isolates the oxygen supply and inhibits the combustion reaction, thus achieving initial fire control.

[0003] Currently, traditional fire blankets extinguish fires by covering the fire source to isolate oxygen. However, these fire blankets only have the function of physically isolating oxygen and lack the ability to actively cool down. For vehicle fires that have entered the stage of intense combustion or have deep heat sources, the fire control effect is limited. Even if the surface flames are temporarily suppressed, the internal temperature may continue to rise, which can easily cause reignition or even explosion.

[0004] Therefore, there is an urgent need for a water-filled automotive flame-retardant blanket that integrates physical flame retardancy and internal water spraying. Utility Model Content

[0005] In order to overcome the shortcomings of traditional fire blankets that only have physical oxygen-barrier function but lack active cooling ability and cannot achieve continuous fire extinguishing operation, this utility model provides a water-filled automotive flame-retardant fire control blanket that integrates physical flame retardant covering and internal water spraying.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a water-filled automotive flame-retardant fire control blanket, comprising a fire control blanket body, wherein the fire control blanket body has a double-layer structure with a closed water storage cavity in the middle, and the inner surface of the fire control blanket body facing the fire source is provided with multiple through holes, the through holes connecting the water storage cavity to the outside, and one end of the fire control blanket body is provided with a water inlet pipe, the water inlet pipe being connected to the water storage cavity.

[0007] Furthermore, the fire control blanket body has reinforcing layers on both sides.

[0008] Furthermore, a corrugated expansion joint is provided at the inlet of the water inlet pipe.

[0009] Furthermore, the fire control blanket body has a first Velcro strip on both sides, a protective cloth on both sides, and a second Velcro strip on the side of the protective cloth facing the fire control blanket body.

[0010] Furthermore, the other end of the fire control blanket body is provided with a first storage rope and a second storage rope.

[0011] Furthermore, the first and second storage ropes are non-elastic high-strength webbing, and their lengths are adapted to the circumference of the fire control blanket after it is rolled up.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By covering the burning vehicle with the fire control blanket body, air is effectively isolated and combustion reaction is suppressed. At the same time, water is continuously injected into the internal water storage chamber through the water inlet pipe. The water is sprayed out evenly through the through holes on the inner surface and directly acts on the fire source for cooling and temperature reduction. This achieves the synergistic effect of oxygen isolation and flame retardancy and active water cooling, significantly improving fire extinguishing efficiency and effectively preventing reignition.

[0013] 2. By setting a Velcro strip structure on the surface of the fire control blanket, protective cloth can be selectively added to improve the resistance to extreme high temperature environments, and to achieve a flexible configuration of basic protection plus on-demand reinforcement to meet the usage requirements of different fire levels.

[0014] 3. The fire blanket has a non-elastic high-strength storage rope on the left end, which can be firmly tied after being rolled up. It is compact in size, easy to store and transport, and can be used with a special storage bag or wall-mounted bracket to improve daily management efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 A water-filled automotive flame-retardant fire control blanket includes a fire control blanket body 1, which has a double-layer structure with a closed water storage chamber 2 in the middle. Multiple through holes 3 are provided on the inner surface of the fire control blanket body 1 facing the fire source, connecting the water storage chamber 2 to the outside. A water inlet pipe 4 is provided at the right end of the fire control blanket body 1, connected to the water storage chamber 2 for connecting to an external water source to inject water into the water storage chamber 2. A corrugated expansion section 5 is provided at the inlet of the water inlet pipe 4 to enhance its bending adaptability and connection convenience, facilitating quick connection with external water supply equipment. Reinforcing layers 6 are provided on both sides of the fire control blanket body 1. The reinforcing layers 6 are made of high-temperature resistant, high-strength mesh fabric to improve water pressure resistance, prevent bulging or leakage of the water storage chamber 2 due to internal pressure, and enhance overall tear resistance and abrasion resistance, extending service life.

[0022] In the early stages of a fire, a fire blanket is quickly placed over the surface of the burning vehicle. Its high-temperature resistant material forms a sealed or semi-sealed space, cutting off the oxygen supply, inhibiting the spread of flames, and reducing the intensity of combustion. Subsequently, a fire water source is connected through the water inlet pipe 4, and high-pressure water is injected into the water storage chamber 2 inside the fire blanket. The water diffuses and is pressurized in the water storage chamber 2, and is evenly sprayed out from multiple through holes 3 on the inner surface, directly spraying onto the burning parts of the vehicle to achieve rapid cooling, cool the burning materials, and inhibit reignition. This achieves synergistic fire control through physical flame retardation and water spraying.

[0023] Example 2: Based on Example 1, please refer to... Figure 3 The fire control blanket body 1 is provided with a first Velcro strip 7 on both sides and a protective cloth 8 on both sides. The protective cloth 8 is made of higher-specification materials such as ceramic fiber composite cloth and metal reflective layer, which can effectively reflect radiant heat, delay heat conduction, and prevent the fire control blanket body 1 from overheating and being damaged. The protective cloth 8 is provided with a second Velcro strip 9 on the side facing the fire control blanket body 1.

[0024] When using the fire blanket, the protective cloth 8 is fixed to the surface of the fire blanket by aligning and bonding the first Velcro strip 7 and the second Velcro strip 9. The additional protective cloth 8 effectively reflects radiant heat and slows down heat conduction, thereby further improving the long-term high-temperature resistance and preventing heat penetration. In addition, the protective cloth 8 can be quickly removed by bonding and fixing it with the first Velcro strip 7 and the second Velcro strip 9, so it can be replaced separately after high temperature or contamination, reducing the maintenance cost of the fire blanket.

[0025] Please see Figure 4 The fire control blanket body 1 is provided with a first storage rope 10 and a second storage rope 11 at its left end. The first storage rope 10 and the second storage rope 11 are non-elastic high-strength webbing, and their lengths are adapted to the circumference of the fire control blanket after it is rolled up.

[0026] After the fire is extinguished or during routine storage, the fire blanket body 1 is rolled into a tube from the outside to the inside and tied in a circular manner using the first storage rope 10 and the second storage rope 11 set at the edge. This ensures that the fire blanket is compact in the stored state and can be quickly untied at the knot of the storage rope during subsequent use, allowing it to be unfolded in one second, thus meeting the needs of rapid response in fire emergencies.

[0027] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
