Description

Technical Field

[0001] The present invention relates to the field of fire-fighting equipment, and particularly to a fire-resistant fire extinguishing device and a method for using the same. Background Art

[0002] Motorcycles and electric motorcycles play an important role in modern transportation. According to relevant statistics, the ownership of motorcycles has been continuously increasing in recent years. Electric motorcycles, with their convenience and economy, are widely used in short-distance urban travel. However, such vehicles have certain fire risks. For traditional fuel motorcycles, their fuel systems are the key sources of fire hazards. During the storage and use of fuel, if leakage occurs and it encounters an open flame or a high-temperature component, it is extremely likely to cause a fire. For example, problems such as aging fuel pipes and loose joints may lead to fuel leakage. Electric motorcycles face the risk of battery fires. With the increasing use of electric motorcycles, battery fire incidents occur from time to time. On the one hand, some lithium batteries used in electric motorcycles may experience thermal runaway and then cause a fire under overcharging, short-circuiting, or high-temperature environments.

[0003] The invention patent with the application number 201710577512.8 discloses a high-quality fire blanket. The fire blanket is made of high-silica glass fiber cloth, and the high-silica glass fiber cloth is woven from high-silica glass fiber yarns. The preparation process of the high-silica glass fiber yarns is as follows: First, the glass fiber rovings are subjected to a process of unwinding and doubling to form glass fiber yarns. Then, the original yarns are subjected to acid leaching, cleaning treatment, pressurization, pressure holding, and pressure reduction cycle treatment, and finally, drying and heat setting treatment are carried out. The present invention has made special improvement treatments on the preparation process of the raw material components for preparing the fire blanket. The obtained high-silica glass fiber yarns have good wear resistance and a large specific surface area. The corresponding fire blanket can effectively adsorb sundries such as soot and dust in a fire, further improving the protection effect. At the same time, it has good strength, wear resistance, and other properties, and the overall service performance is better and the lifespan is longer.

[0004] The above technology has increased the fire extinguishing performance by improving the material of the fire blanket. However, the fire blanket is usually used when a fire breaks out. For example, when a motorcycle catches fire, the burning area may be relatively large and the fire may be relatively fierce. When a person covers the fire blanket, it is easy to be roasted by the flames escaping outside, resulting in personal injury, or the high temperature causes the fire blanket to slip out of the hand, missing the fire extinguishing opportunity. Therefore, there is a need for a technology to protect personnel when covering the fire blanket. Summary of the Invention

[0005] The present invention provides a fire-resistant fire extinguishing device and a method for using the same, which can protect the staff from injury when they cover the fire blanket.

[0006] To solve the above technical problems, the present application provides the following technical solution: A fire-resistant fire extinguishing device, comprising: Base: The base has two layers, and the material of the base is basalt fiber cloth made of basalt fiber material. The two layers of the base are fixedly connected; the base is rectangular; Silicone coating: Coated on the surface of the basalt fiber cloth; Traction ropes: There are two traction ropes, which are fixed on the short sides of the base; the two traction ropes are symmetrically arranged along the axis of the short side; First gas pipeline: Fixed on the short side of the base where the traction ropes are located; First nozzle: The first nozzle is opened at one end of the first gas pipeline away from the base. There are several first nozzles, and the first nozzles are oriented in the extending direction of the axis of the short side of the base; the first nozzles are symmetrically arranged along the axis of the short side of the base; Carbon dioxide chamber: Arranged between the two bases, used to generate carbon dioxide gas before laying, and transmit it to the first gas pipeline and spray out from the first nozzles.

[0007] Basic principle and beneficial effects of this solution: When a motorcycle catches fire, unfold the fire extinguishing blanket. Two workers each pull a traction rope to drag the fire extinguishing blanket to cover the motorcycle. The carbon dioxide generated in the carbon dioxide chamber is sprayed out from the first nozzles. Since the nozzles are oriented towards the flame area and the sprayed gas is carbon dioxide, it can inhibit the protruding flames and make the flames converge towards the center. When the workers drag the fire extinguishing blanket, there will be no external flames to harm the two workers on both sides. That is, while protecting the workers, it also reduces the obstacles during the process of covering the fire extinguishing blanket and improves the fire extinguishing efficiency.

[0008] Further, the basalt fiber cloth is made of basalt fiber yarn with a diameter of 9μm to 17μm and a linear density of 133tex to 233tex, and is woven by a plain weave, satin weave or twill weave; the areal density is 200g / m2 to 400g / m2.

[0009] Further, the carbon dioxide chamber includes a first chamber and a second chamber. In the second chamber; the second chamber is airtight, and dilute hydrochloric acid is provided in the second chamber. Limestone is placed in the first chamber. A diaphragm is provided between the first chamber and the second chamber. The first chamber is connected with a transmission pipe, and the other end of the transmission pipe is connected with an air duct, and the air duct is connected with the first gas pipeline through a first conduit.

[0010] Beneficial effects: The carbon dioxide chamber is initially arranged inside the base of the fire extinguishing blanket. When it is activated at the fire scene, that is, when dilute hydrochloric acid and limestone are mixed, a large amount of carbon dioxide gas will be generated. The carbon dioxide gas is sprayed out from the first nozzles, which can help the workers clear the flames on the way forward and prevent accidental injuries.

[0011] Further, the air duct is parallel to the axis of the short side of the base, and the air duct is sewn between two bases. The air duct is also connected to a second air duct, and the other end of the second air duct is connected to a plurality of second air pipes; the second air pipes are parallel to the long side of the base and are arranged at intervals on the base; a plurality of second nozzles are provided on the second air pipes.

[0012] Beneficial effects: The setting of the second nozzles enables more positions on the fire extinguishing blanket to eject carbon dioxide gas. The generation of carbon dioxide can not only control the fire, but also, when the second nozzles are located above the fire extinguishing blanket (the lower side of the fire extinguishing blanket is the side directly in contact with the flame), when the carbon dioxide is ejected from the second nozzles, it will also push the fire extinguishing blanket towards the flame, that is, it can strengthen the adhesion of the fire extinguishing blanket to the motorcycle on fire, reduce the probability of the spread of the flame, and at the same time, the carbon dioxide ejected from the second nozzles will also move along the fire extinguishing blanket towards the ground, preventing gaps from appearing on the fire extinguishing blanket, so that air can enter the motorcycle through the gaps on the fire extinguishing blanket, allowing the sparks to obtain oxygen for combustion, that is, blocking the entry of oxygen.

[0013] Further, a valve block is slidably connected in the air duct, and the connection position of the air conveying pipe and the air duct is located between the connection position of the first air duct and the air duct and the connection position of the second air duct and the air duct; when the valve block is in the initial position, the air conveying pipe and the first air duct are connected; when the valve block is in the terminal position, the air conveying pipe and the second air duct are connected; a pull rope is further included, one end of the pull rope is fixed to the valve block, and the other end extends out of the air duct and is integrated on the traction rope; the pull rope is used to pull the valve block from the initial position to the terminal position.

[0014] Beneficial effects: When covering the fire extinguishing blanket, controlling the carbon dioxide to be ejected from the first nozzle can help the staff clear the flames on the way forward. After covering, the valve body is controlled to move through the pull rope, closing the communication channel of the carbon dioxide at the first nozzle and opening the communication channel of the second nozzle, so that the carbon dioxide is only ejected from the second nozzle, reducing the loss of carbon dioxide.

[0015] Further, a spring is further included, one end of the spring is fixed to the end of the valve block away from the stretching direction, and the other end of the spring is fixed to the inner wall of the air duct. The spring is used to keep the valve block in the starting position when it is not affected by external forces.

[0016] Beneficial effects: Prevent the pull rope from being accidentally touched and causing the valve block to be misaligned.

[0017] Further, a valve is provided on the diaphragm. When the valve is opened, the dilute hydrochloric acid located in the second chamber enters the first chamber through the valve.

[0018] Further, a plurality of folding areas for folding the fire extinguishing blanket during storage are provided between the two short sides of the base, and the second air delivery pipe is sewn in the folding areas.

[0019] Further, the base is made of basalt fiber material, and the first air guide pipe, the second air guide pipe, the first air delivery pipe, and the second air delivery pipe are all pipes made of basalt fiber material.

[0020] A method for using a fire-resistant fire extinguishing device includes the following steps: S1: Fold the prepared fire extinguishing blanket with the folding area as the crease for standby; S2: Transport the folded fire extinguishing blanket to the fire extinguishing area. Two people each pull a long side of the base, unfold the fire extinguishing blanket, and then open the valve on the diaphragm so that the dilute hydrochloric acid in the second chamber flows into the first chamber to react with the limestone; S3: Two workers respectively drag a traction rope and move from both sides of the fire to cover the vehicle on fire; S4: After covering, the two workers continue to stretch the pull rope integrated in the traction rope to lift the valve block to the end position.
