Description

Technical Field

[0001] This utility model relates to the field of fire suppression and control blanket technology, specifically a fire suppression and control blanket for new energy vehicles. Background Technology

[0002] Fire blankets are specialized firefighting equipment designed specifically for the characteristics of battery fires in new energy vehicles. They are primarily used to suppress the spread of thermal runaway from the battery, block high-temperature radiation, and assist in fire suppression. When in use, if the battery pack has not experienced an explosion, the fire blanket is directly placed over it to suppress the fire, and combined with a water-based fire extinguisher for cooling, thus completing the fire suppression. However, existing fire blankets have some shortcomings, such as: Existing fire control blankets are mainly made of traditional fiberglass, which has low temperature resistance and small area, making them difficult to adapt to the complex on-site environment of new energy vehicles.

[0003] Therefore, we propose a fire control blanket for fire suppression in new energy vehicles to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a fire control blanket for fire suppression in new energy vehicles, in order to solve the problem mentioned in the background art that the fire control blankets currently on the market are made of traditional fiberglass, which have low temperature resistance and small area, making them difficult to adapt to the complex on-site environment of new energy vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire control blanket for fire suppression in new energy vehicles, comprising flame-retardant aramid and an aramid woven strip disposed on the outer side of the flame-retardant aramid; The flame-retardant aramid is connected to six sets of fire-control blanket composite layers on the inner side, and the composite layer includes fire-resistant carbon fiber cloth, and the bottom of the fire-resistant carbon fiber cloth is connected to heat-resistant carbon fiber cloth. The outer sides of the fire-resistant carbon fiber cloth and the heat-resistant carbon fiber cloth are connected and edged with the flame-retardant aramid, and the composite layers are connected by seams. The outer edge of the fire-control blanket composite layer is connected to the flame-retardant aramid. The flame-retardant aramid is edged with steel wire, and the steel wire is fixedly connected to the flame-retardant aramid, and the flame-retardant aramid is fixedly connected to the aramid braided tape.

[0006] By wrapping the edges of the fire control blanket composite layer with flame-retardant aramid, it is possible to prevent battery slurry from penetrating the inner layers of the fire-resistant carbon fiber cloth and heat-resistant carbon fiber cloth when covering the car battery, thus avoiding any impact. Furthermore, since the device consists of six sets of fire control blanket composite layers, it can cover a large area of ​​the car to extinguish the fire source. It can also release more than forty kinds of high-temperature combustion gases when the battery is burning, thereby lowering the temperature and suppressing the flames to extinguish them.

[0007] As a preferred technical solution of this utility model, the unit area mass of the fire control blanket composite layer is less than 700g / ㎡, and the oxygen index of the fire-resistant carbon fiber cloth and the heat-resistant carbon fiber cloth should not be less than 35.0%, and the resistance between the two sides of the fire control blanket composite layer is not less than 1MΩ. The fully unfolded shape of the fire control blanket composite layer is rectangular, and the length-to-width ratio is 9:6.

[0010] The above technical solution enables the connection between fire-resistant carbon fiber cloth and heat-resistant carbon fiber cloth to be more stable, thereby increasing the strength of the fire control blanket composite layer during sewing.

[0011] As a preferred technical solution of this utility model, a first steel wire mesh is provided on the top of the carbon fiber connecting layer, and the top of the first steel wire mesh is connected and attached to the fire-resistant carbon fiber cloth. A second steel wire mesh is provided at the bottom of the carbon fiber connecting layer, and the bottom of the second steel wire mesh is connected and attached to the heat-resistant carbon fiber cloth.

[0012] The above technical solution enables the first and second steel wire meshes to limit the refractory carbon fiber cloth and the heat-resistant carbon fiber cloth when they are unfolded, thereby preventing the refractory carbon fiber cloth and the heat-resistant carbon fiber cloth from tearing due to excessive force during unfolding.

[0013] As a preferred technical solution of this utility model, both the outer sides of the first wire mesh and the second wire mesh are provided with wire joints, and the fire control blanket composite layers can be connected through the wire joints when they are connected to each other. Furthermore, the first wire mesh and the second wire mesh are connected to the wire edging through the wire joints.

[0014] The above technical solution enables the fire control blanket composite layers to be connected internally via steel wire joints and then connected via seams, thereby increasing the strength of the connection between multiple fire control blanket composite layers.

[0015] As a preferred technical solution of this utility model, the flame-retardant aramid fiber has a fixed edge inside, and the fixed edge can be bonded and connected with the carbon fiber connecting layer.

[0016] The above technical solution enables flame-retardant aramid fibers to be connected through a fixed edge carbon fiber connecting layer, thereby increasing the stability of the flame-retardant aramid fibers when connected with the fire control blanket composite layer.

[0017] As a preferred technical solution of this utility model, a take-up roller is provided on the outside of the flame-retardant aramid, and a connecting roller is provided on the outside of the take-up roller. The connecting roller is fixedly connected to the aramid braided belt. A connecting belt is connected to the outside of the take-up roller, and a limiting suction cup is provided at the top of the connecting belt. A buckle is provided at the other end of the connecting belt. The connecting belt can be connected to the take-up roller through the buckle.

[0018] The above technical solution enables the equipment to be operated through the winding roller when winding or unwinding, and to be limited by the connecting belt, thereby preventing the equipment from deviating during use.

[0019] Compared with the prior art, the beneficial effects of this utility model are: by wrapping the edges of the fire control blanket composite layer with flame-retardant aramid, it can prevent the battery slurry from penetrating the inner layer of the fire-resistant carbon fiber cloth and heat-resistant carbon fiber cloth when covering the car battery, thus avoiding any impact. Furthermore, since the device consists of six sets of fire control blanket composite layers, it can cover a large area of ​​the car to extinguish the fire source, and can release more than forty kinds of high-temperature combustion gases when the battery is burning, thereby lowering the temperature and suppressing the flames to extinguish them. Furthermore, the carbon fiber connecting layer makes the connection between the fire-resistant carbon fiber cloth and the heat-resistant carbon fiber cloth more stable, thereby increasing the strength of the fire control blanket composite layer during sewing. Furthermore, by setting up the first and second wire meshes, the refractory carbon fiber cloth and the heat-resistant carbon fiber cloth can be limited by the first and second wire meshes when they are unfolded, thereby preventing the refractory carbon fiber cloth and the heat-resistant carbon fiber cloth from tearing due to excessive force when unfolded.

At the same time, more than forty kinds of gases from the battery fire source will also pass through the fire-resistant carbon fiber cloth 1 and the heat-resistant carbon fiber cloth 2 and be released, thereby preventing the battery fire source from continuing to burn gases.
