[0014] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0015] Embodiment 1 The present invention discloses a method as Figures 1-4The shown vehicle fire extinguishing device includes a folding frame 1, which is an inverted U-shaped structure with openings at the front and rear ends and connected at the sides and top, composed of multiple sections of rigid support rods hinged to each other. The length of the inverted U-shaped structure 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 vehicle and can be folded into a shorter state when stored idle. A cover 4 is provided outside the folding frame, and the cover is made of fire-resistant and high-temperature-resistant material. A transparent glass 7 is installed at the rear end of the folding frame, through which the internal fire situation can be observed. A curtain body 5 is provided at the front opening of the cover. The curtain body is similar to a rolling shutter door structure. When the vehicle body needs to be covered, the curtain body 5 can extend to a state equal in height to the inverted U-shaped structure. To improve the sealing performance of the entire device and completely isolate the vehicle body from the outside world, sealing seats 3 are installed at the lower ends of both the cover 4 and the curtain body 5. The sealing seats are made of high-temperature-resistant and fire-resistant elastic material. The sealing seat 3 is in the shape of a bottom-opening shell, and an exhaust valve is provided on the upper surface of the shell. There are two types of sealing seats 3. One type is longitudinally installed 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 the left and right sides. The other type is horizontally installed at the end of the curtain body 5, sealing the curtain body 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 body 5 descends to the ground. Whether it is the sealing seat at the bottom of the cover 4 or the sealing seat at the bottom of the curtain body, it is rotatably connected to the corresponding structure (cover or curtain body) in the horizontal direction and is normally in a state with the opening facing outwards. As Figures 3-4 shown, when the fire extinguishing device is needed to isolate the burning vehicle body from the outside world, the sealing seat 3 is rotated 90 degrees to the state with the opening facing downwards, and the sealing seat 3 is pressed downwards. The gas between the sealing seat shell and the ground is discharged from the exhaust valve, and the sealing seat is adsorbed on the ground under the action of atmospheric pressure, realizing the closed space formed by the cover 4 and the curtain body 5 and the ground, isolating the combustion source inside the fire extinguishing device from the outside world, and extinguishing the fire in an oxygen-deficient state.

[0016] Embodiment 2 To further quickly extinguish the fire, an air inlet 2 is provided on the side of the cover 4. Through the air inlet 2, heptafluoropropane gas is introduced into the sealed fire extinguishing device to extinguish the fire as soon as possible. To prevent leakage, an intake one-way valve is provided at the air inlet 2, that is, only gas can be introduced through this air inlet, and the internal gas cannot diffuse outwards.

[0017] To improve the sealing performance, the edge of the cover is designed in a horizontally placed U-shaped opening shape, and an elastic sealing strip is provided at the opening. The two sides of the curtain body are inserted into the elastic sealing strip. The elastic sealing strip is also selected from fire-resistant and high-temperature-resistant materials.

[0018] To timely discharge the gas generated after combustion inside the fire extinguishing device, an air outlet is also provided on the cover 4, and a filtering device is provided at the air outlet to filter and process the toxic gas and only discharge clean gas.

[0019] To facilitate the movement of the fire extinguishing device, a vertically telescopic roller 6 is provided at the lower part of the inner side of the cover 4. The installation height of the roller is lower than the bottom height of the sealing seat 3 when its opening faces outward but higher than the bottom height of the sealing seat 3 when its opening faces downward.

[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
