Description

Technical Field

[0001] The present invention relates to the technical field of firefighting and lifesaving equipment, and in particular to a method for preparing a fire blanket for a new energy vehicle. Background Art

[0002] With the increasing attention paid to environmental protection around the world, the new energy vehicle industry has developed rapidly. However, while new energy vehicles bring many advantages such as environmental protection and energy saving, they also face safety hazards that cannot be ignored, especially fire problems. The battery pack of new energy vehicles contains a large amount of electrical energy, which is very easy to cause fires in the case of thermal runaway, short circuit, collision, etc. of the battery. And because the battery fire burns quickly and at high temperatures, the large amount of toxic gases and heat released will not only cause serious damage to the vehicle, but also pose a huge threat to the life safety of the driver and passengers. At present, for new energy vehicle fires, traditional fire extinguishing methods such as dry powder fire extinguishers and carbon dioxide fire extinguishers have certain limitations in practical applications. Although dry powder fire extinguishers can suppress flames, it is difficult to fundamentally block the heat release of high-temperature battery fires, and after use, it will cause a certain degree of pollution and damage to vehicle equipment. Carbon dioxide fire extinguishers mainly extinguish fires by reducing oxygen concentration. For some electrical fires, the fire extinguishing effect is limited, and when used in a small space, it may cause suffocation. As an important fire-fighting tool, fire blankets have unique advantages in dealing with various fire scenes. However, most of the existing fire blankets are not specially designed for the special fire characteristics of new energy vehicles. Ordinary fire blankets cannot meet the needs of effectively extinguishing new energy vehicle fires in terms of high temperature resistance, heat insulation performance, and adaptability to the complex environment of new energy vehicles. Therefore, it has become an urgent problem to develop a fire blanket specifically suitable for new energy vehicles, which has efficient fire prevention and heat insulation performance, can quickly play a role when a new energy vehicle fire occurs, effectively control the spread of fire, and ensure the safety of personnel and vehicles.

[0003] The invention patent with application number 201410757962.1 discloses a method for making a glass fiber fire blanket and its coating, which uses a water-soluble mixture to coat the glass fiber base cloth by dipping, forming a dense layer of fire-retardant coating on the surface of the glass fiber base cloth, making the coated glass fiber fire blanket surface soft and airtight, isolating the flame from the air, thereby achieving the purpose of extinguishing the fire. At the same time, the present invention can also provide protection for personnel to escape and avoid the harm caused by the flame to the human body. When used as a fire curtain, it can also effectively prevent the spread of flames and has the characteristics of wide application.

[0004] The above technology can achieve the purpose of extinguishing fire by using fire-retardant coating and glass fiber in combination. However, if only a fire blanket composed of insulating coating and glass fiber is used to isolate oxygen from the burning vehicle to extinguish the fire, the fire extinguishing efficiency is relatively low. Therefore, a technology is needed to improve the efficiency of cooling and extinguishing fire when new energy vehicles catch fire. Summary of the invention

[0005] The present invention provides a method for preparing a fire extinguishing blanket for new energy vehicles, which can improve the fire extinguishing efficiency of new energy vehicles.

[0006] In order to solve the above technical problems, this application provides the following technical solutions: 1. A method for preparing a fire blanket for new energy vehicles, characterized in that it comprises the following steps: S1: Cut two pieces of basalt fiber cloth as the base according to the preset size; S2: coating the cut basalt fiber cloth with a coating; S3: planning the water hose laying area on the opposite sides of the two basalt fiber cloths; S4: After installing the basalt braided water hose on the water hose laying area, sew two pieces of basalt fiber cloth together; the basalt braided water hose is arranged between the two pieces of basalt fiber cloth; and a plurality of water leakage holes are arranged at intervals on the basalt braided water hose; S5: Perform hole opening treatment on the basalt fiber cloth covering the leaking hole.

[0007] The basic principle and beneficial effects of this scheme: This scheme selects basalt fiber cloth as the base material of the fire blanket, cuts off the basalt fiber cloth of the size that meets the specifications for use, then plans an area for installing the basalt braided water hose in the basalt fiber cloth, and then sews the basalt braided water hose between two pieces of basalt fiber cloth. The basalt braided water hose is provided with leakage holes at intervals. After the basalt fiber cloth is sewn, the prototype of the fire blanket is formed. After finding the position of each leakage hole in turn, cut the basalt fiber cloth covering it to expose the leakage hole, so that in the later stage of fire extinguishing, water can be passed through the basalt braided water hose, and the water will flow out from the leakage hole to cool down and extinguish the fire.

[0008] In this solution, a basalt braided water hose is installed on the fire blanket. When extinguishing a fire, the fire blanket is first covered on the burning new energy vehicle, and then water is passed into the basalt braided water hose, and the water in the hose flows out from the leaking holes. First, the fire blanket will isolate the contact between oxygen and the burning new energy vehicle, and can achieve flame retardancy. At the same time, due to the addition of a water source, the water flow can take away heat during the flow, and quickly take away the heat, which improves the efficiency of cooling and fire extinguishing.

[0009] In this solution, basalt fiber cloth and basalt braided hose are both environmentally friendly materials. Their production process has low energy consumption and little pollution. They will not release harmful substances during use. They are environmentally friendly and in line with the green development concept of new energy vehicles. Basalt fiber cloth has excellent high temperature resistance and can withstand the high temperature generated by new energy vehicle fires. It will not burn or melt due to high temperature, ensuring that the fire blanket can continue to play a role at the fire scene and provide reliable protection for fire fighting. Basalt fiber cloth and basalt braided hose have high mechanical strength and can withstand certain external impact and pulling. They are not easy to break. Even in complex fire scene environments, they can maintain the integrity and stability of the fire blanket and extend its service life. Basalt fiber cloth has good thermal insulation properties. When the fire blanket is covered on a new energy vehicle on fire, it can effectively prevent heat from being transferred to the surrounding environment, reduce the risk of fire spreading, and protect firefighters from high temperature damage, thereby improving the safety of fire fighting operations. After the fire is extinguished, the fire blanket is simply cleaned and inspected. If there is no damage, it can be put into use again, which improves the utilization rate of resources, reduces the dependence on disposable fire extinguishing materials, and has good economic efficiency. The fire blanket is not only suitable for extinguishing fires in new energy vehicles, but also can be used for fire protection in other similar flammable and explosive places. It has a broad market application prospect and can provide effective solutions for fire safety in different scenarios.

[0010] Further, the hole-making step in step S5 is: S51: Determine the location of the water leakage hole; S52: I-shaped holes are made in the basalt fiber cloth near the leaking hole: first, the leaking hole is determined as the center point, and a horizontal line is drawn on the basalt fiber cloth at a threshold distance upward and downward from the center point, and the two horizontal lines are parallel to the water flow direction of the basalt woven water hose; then, a vertical line is drawn on the basalt fiber cloth through the center point in sequence to the two horizontal lines, and the two horizontal lines and the vertical line form an I-shape; S53: folding the basalt fiber cloth divided on both sides of the vertical line, and fixing it on the uncut basalt fiber cloth; S54: Secondary coating of the cut locations on the basalt fiber cloth.

[0011] Furthermore, a water inlet joint is installed at the place where the basalt braided water hose in step S4 extends out of the basalt fiber cloth.

[0012] Furthermore, the divided basalt fiber cloth is rectangular, the water hose laying area in step S3 is distributed in a U-shape, the basalt woven water hose at the water inlet end of the water hose laying area extends to the short side of the basalt fiber cloth, and the water inlet joint is installed on the basalt woven water hose at the water inlet end, and the water inlet joint is fixedly connected to the basalt fiber cloth.

[0013] Beneficial effect: A consistent cutting and opening method is used to open holes at the location of the leaking hole. The incision is in the shape of an I, that is, cutting is performed on the basalt fiber cloth above and below the leaking hole. Two parallel horizontal lines are drawn first, and then a vertical line is drawn between the two horizontal lines. The vertical line passes through the center point. The two horizontal lines and the vertical line form an I-shape. The two pieces of basalt fiber cloth cut by the horizontal and vertical lines are folded and fixed on the uncut basalt fiber cloth, which can release the leaking hole. The basalt fiber cloth after I-shaped cutting is folded and fixed, which increases the thickness and layering of the fiber cloth in the leaking hole area, which is equivalent to forming a local reinforcement structure around the leaking hole, thereby improving the overall strength and deformation resistance of the fire blanket, so that it can better withstand heavy pressure and pulling force when covering fire extinguishing objects such as new energy vehicles, reduce the risk of damage caused by local uneven force, and extend the service life of the fire blanket. The U-shaped water hose layout area allows the water flow to be evenly distributed around the fire blanket. When the water flows into the basalt woven water hose from the water inlet joint, it can quickly flow along the four sides of the water hose and spray out evenly through each water leakage hole to form a full range of water mist or water flow coverage, effectively improving the cooling and fire extinguishing range and efficiency of the fire blanket, avoiding the problem of poor local fire extinguishing effect caused by uneven water flow distribution, and ensuring that the fire part of the entire new energy vehicle can be cooled and extinguished in a timely and effective manner.

[0014] Furthermore, it also includes a traction rope, which is symmetrically fixed on the same short side of the basalt fiber cloth.

[0015] Beneficial effect: It is convenient to drag the fire blanket when extinguishing a fire, so that the fire blanket can be quickly covered on the new energy vehicle.

[0016] Furthermore, in step S4, after a leaking hole is opened on the basalt braided water hose, an iron ring buckle is used to fix the leaking hole, and an airbag is also provided on the iron ring buckle. The bag body of the airbag is arranged on the outside of the basalt braided water hose, and the air port of the airbag is fixed at one end of the iron ring buckle on the inner side of the basalt braided water hose. The space inside the basalt braided water hose and the airbag is connected, and the connection between the basalt braided water hose and the airbag is sealed.

[0017] Beneficial effect: With the setting of the airbag, after ventilation, the airbag will be blocked between the basalt fiber cloth and the basalt fiber hose. The expansion point of the airbag is the center point, that is, the location of the leak can be quickly determined. There is no need to determine the location of the leak by touching the basalt fiber cloth as before. This solution can quickly and accurately determine the location of the leak. At the same time, due to the spacing of the airbag, the basalt fiber cloth and the basalt woven hose are separated. When cutting the basalt fiber cloth, it can prevent the knife from scratching the basalt woven hose after cutting the basalt fiber cloth, causing leakage during subsequent use. And because after the basalt fiber cloth is cut, there will be some sharp edges and burrs at the cutting position due to the material of the fiber cloth. When the hand touches it directly, there will be a pricking feeling on the hand; when the cutting position is indirectly contacted by the airbag, hand injuries can be avoided.

[0018] Furthermore, in step S5, before opening holes in the basalt fiber cloth, gas is introduced through the water inlet joints at the two short sides of the basalt fiber cloth or through the water inlet joint on one side that is blocked, so that the airbag expands.

[0019] Furthermore, at least two thresholds are set for the amount of gas introduced into the basalt woven water hose. When the amount of gas introduced reaches the first threshold, the center point is determined by the raised point on the basalt fiber cloth, and an I-shaped hole is opened near the center point. After the hole opening is completed, glue is applied to the side of the basalt fiber cloth divided on both sides of the vertical line to be folded away from the basalt woven water hose, and then gas is continuously introduced into the basalt woven water hose to the second threshold, so that the airbag expands to the maximum value, and the airbag abuts the divided basalt fiber cloth and makes it close to the uncut basalt fiber cloth.

[0020] Beneficial effects: At the first threshold, the airbag will form a space between the basalt fiber cloth and the basalt fiber hose, which is convenient for cutting and can also prevent the airbag from expanding too much. When cutting, the airbag is cut. After the two horizontal lines are cut, the vertical lines are cut with scissors, and then glue is applied to the cut basalt fiber cloth. Then the gas volume is increased to the second threshold, and the airbag expands to the maximum. The two cut basalt fiber cloths are attached to the uncut basalt fiber cloth, and the airbag will continue to press the cut basalt fiber cloth to facilitate the solidification and hardening of the glue. After the glue solidifies, the airbag is reduced to the gas volume of the first threshold, and then the incision position of the basalt fiber cloth and the exposed part of the cut basalt braided water hose are sprayed with paint, which can not only improve the fireproof performance, but also cover the burr part to prevent it from hurting the hand. It will not cause injuries to workers or users when leaving the factory and in subsequent use, and will not affect the firefighting process. At the same time, due to the presence of the airbag, the connection between the basalt woven water hose and the outside world is blocked. When spraying, it can prevent the paint from entering the basalt woven water hose through the leakage holes, and it can also prevent the leakage holes from being blocked.

[0021] Further, after the glue solidifies, the amount of gas in the basalt woven water hose is reduced to a first threshold value, and then the cutting position is sprayed with paint and then leveled; after the leveling is completed, the air bag is removed.

[0022] Furthermore, the method further comprises step S6: folding and packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As attached Figure 5As shown, an air bag 82 is fixed on each iron ring buckle 81. Before opening a hole in the basalt fiber cloth 5, gas is introduced through the water inlet joints at the two short sides of the basalt fiber cloth 5 or the water inlet joints on one side that are blocked from the water inlet joints on the other side, so that the air bag 82 expands, and the basalt braided water hose will also expand synchronously.
