Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection facilities and equipment, specifically to a car fire extinguishing device. Background Technology
[0002] With the promotion and development of new energy vehicles, there are more and more new energy vehicles. However, the special structure of new energy vehicles has also led to an increase in spontaneous combustion. Due to the flammability and strong diffusion of the electrolyte in new energy vehicles, the release of oxygen intensifies the fire, and the complex ignition point accelerates the spread of the fire, fires in new energy vehicles can cause greater property damage than ordinary fires.
[0003] In enclosed and densely populated underground parking lots, spontaneous combustion can be detrimental to vehicles and buildings if fire trucks cannot reach them in time, endangering not only other vehicles and buildings but also posing a significant threat to lives. Therefore, finding a quick and efficient way to extinguish spontaneously combusting new energy vehicles has become an urgent problem to solve. Utility Model Content
[0004] To address the aforementioned problems, this utility model discloses a car fire extinguishing device. This device uses a closed structure composed of a cover and a curtain to enclose the burning car and uses a fire extinguishing agent to extinguish the fire inside the closed cover. It effectively isolates the fire source from the surrounding environment before extinguishing the fire, which is efficient, fast, and reduces property damage.
[0005] A car fire extinguishing device includes a folding frame, which is an inverted U-shaped structure with openings at the front and rear ends and connections at the sides and top. A cover is provided on the outside of the folding frame, and a retractable curtain is provided at the front opening of the folding frame. A transparent glass is provided at the rear end of the cover. The cover, the transparent glass, and the curtain form a sealed structure with an opening at the bottom.
[0006] Preferably, the bottom of the folding frame and the transparent glass, and the end of the curtain are all rotatably provided with ventable sealing seats. The sealing seats are shells with bottom openings, and the upper surface of the shells is provided with vent valves.
[0007] Preferably, the cover is provided with an air inlet, and an air inlet one-way valve is provided at the air inlet.
[0008] Preferably, an elastic sealing strip is provided at the joint between the cover and the curtain.
[0009] Preferably, the cover is further provided with an air outlet, and a filter device is provided at the air outlet.
[0010] Preferably, the lower part of the inner side of the cover is provided with retractable rollers.
[0011] Beneficial effects
[0012] This invention utilizes a folding frame, an external cover, transparent glass, and a curtain to form a closed structure with an opening at the bottom. A sealing seat secures the entire structure to the ground, completely isolating the burning vehicle from the outside environment. This creates an oxygen-deficient environment within the closed structure, preventing the fire from spreading further. Extinguishing agent is sprayed into the closed structure through an air inlet to extinguish the fire as quickly as possible. The transparent structure facilitates observation of the internal fire situation, allowing for timely assessment of the scene and prompt decision-making. Attached Figure Description

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0020] Example 1
[0021] This utility model discloses a method such as Figure 1-4The illustrated car fire extinguishing device includes a folding frame 1, which is an inverted U-shaped structure consisting of multiple rigid support rods hinged together. The frame has openings at the front and rear ends, and connections at the sides and top. The length of the inverted U-shape can be adjusted by rotating the support rods around their respective hinge points. It is in an extended state when used to isolate a burning car and can be folded into a shorter state when not in use. A cover 4, made of fire-resistant and high-temperature-resistant material, is installed outside the folding frame. A transparent glass 7 is installed at the rear end of the folding frame, allowing observation of the fire inside. A curtain 5, similar to a roller shutter, is installed at the front opening of the cover. When the car body needs to be covered, the curtain 5 can extend to the same height as the inverted U-shape. To improve the sealing performance of the entire device and completely isolate the car body from the outside, sealing seats 3 are installed at the lower ends of both the cover 4 and the curtain 5. These sealing seats are made of high-temperature-resistant and fire-resistant elastic material and are shell-shaped with an opening at the bottom. An exhaust valve is installed on the upper surface of the shell. There are two types of sealing seats 3. One type is installed longitudinally on the left and right sides of the bottom of the inverted U-shaped structure of the cover, sealing the bottom of the cover 4 to the ground on both sides. The other type is installed horizontally at the end of the curtain 5, sealing the curtain 5 to the ground on the front and rear sides of the bottom of the inverted U-shaped structure of the cover after the curtain 5 descends to the ground. Both the sealing seats at the bottom of the cover 4 and the sealing seats at the bottom of the curtain are horizontally rotatably connected to the corresponding structure (cover or curtain), and are normally open facing outwards. Figure 3-4 As shown, when it is necessary to use the fire extinguishing device to isolate the burning vehicle body from the outside world, rotate the sealing seat 3 90 degrees to the opening facing downwards, press the sealing seat 3 down, and the gas between the sealing seat shell and the ground is discharged from the exhaust valve. Under the action of atmospheric pressure, the sealing seat is adsorbed onto the ground, realizing the closed space formed by the cover 4 and the curtain 5 and the ground, so that the combustion source inside the fire extinguishing device is isolated from the outside world and extinguished in the absence of oxygen.
[0022] Example 2
[0023] To further expedite fire extinguishing, an air inlet 2 is provided on the side of the enclosure 4. Heptafluoropropane gas is introduced into the sealed fire extinguishing device through this air inlet 2 to extinguish the fire as quickly as possible. To prevent leakage, a one-way valve is installed at the air inlet 2, meaning that gas can only be introduced through this air inlet, and the internal gas cannot diffuse outward.
[0024] To improve sealing performance, the edges of the cover are designed with a horizontal U-shaped opening, with an elastic sealing strip installed at the opening. The two sides of the curtain are inserted into this elastic sealing strip. This elastic sealing strip is also made of fire-resistant and high-temperature resistant material.
[0025] In order to promptly remove the gases produced by combustion inside the fire extinguishing device, an air outlet is also provided on the cover 4. A filter device is installed at the air outlet to filter out the toxic gases and release only clean gases.
[0026] To facilitate the movement of the fire extinguishing device, a retractable roller 6 is provided on the lower inner side of the cover 4. The installation height of the roller is lower than the bottom height of the sealing seat 3 when the opening faces outward, but higher than the bottom height of the sealing seat 3 when the opening faces downward.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
