[0013] Beneficial effects:

[0014] 1. The utility model can combine the fireproof cover with the fire truck through the arrangement of the fireproof cover, lifting assembly, telescopic arm, upper fixing frame and lower fixing frame. In case of fire, the fireproof cover can be used to isolate the burning car from surrounding cars or equipment conveniently and quickly to prevent the fire from spreading. In combination with the arrangement of the fire sprinkler, the open flame can be extinguished. At the same time, a water pool is formed in the fireproof cover to immerse the battery, cool the battery, and isolate oxygen to achieve the ultimate purpose of fire extinguishing. Compared with the existing water gun fire extinguishing method, it can improve the fire extinguishing efficiency, greatly save water resources, and can be operated remotely. The fire hood is operated without the need for firefighters to approach, which greatly improves the safety performance. The specific process is that when a car catches fire, the fire truck moves to the vicinity of the burning car, and the hydraulic system of the fire truck controls the telescopic arm to extend and retract and drive the fire hood toward the burning car. At the same time, the hydraulic system controls the two hydraulic rods to extend synchronously, so that enough space is formed inside the fire hood until the lower fixed frame at the lower end of the fire hood contacts the ground and forms a closed space. At this time, the fire hood completely wraps the burning car, and the fire sprinkler is manually opened to cool the inside of the fire hood and extinguish the open fire, and accumulate water to form a pool of water to immerse the burning battery.

[0015] 2. The utility model can further prevent the spread of fire by setting a whole circle of sandbags, reduce the loss of water in the pool, and increase the weight, effectively preventing the fireproof cover from being washed away by the water flow; the sandbag circle is located on the side of the lower fixing frame close to the car, and the bottom of the sandbag circle is lower than the bottom of the lower fixing frame, so that the fireproof cover can be further prevented from being washed away by the water flow by utilizing the blocking of the lower fixing frame and the gravity of the water itself. Specifically, at the beginning, the impact force of water on the sandbag circle will be blocked by the lower fixing frame. As the amount of water increases, when the water level is higher than the sandbag circle, the water above the sandbag circle will provide a downward force on the sandbag circle, and this force will increase as the amount of water increases; the fireproof cover can be supported by the auxiliary support frame, the impact resistance of the fireproof cover is improved, and the shape of the fireproof cover is effectively maintained.

[0016] 3. In the utility model, by means of the first bracket, the second bracket, the upper slider rail, the movable support and the hydraulic rod, the folding and unfolding of the fireproof cover can be realized conveniently and quickly, and the height of the fireproof cover can be adjusted to meet the use of cars of different heights. In addition, the overall thickness after folding can be ensured to be minimized, thereby reducing the space occupied by the fireproof cover on the fire truck; by means of the connecting rod, the two lifting components can be ensured to move synchronously.

[0017] 4. The utility model provides a vent hole to facilitate the discharge of gas inside the fireproof cover, achieving an automatic pressure relief effect. Combined with the setting of a one-way valve, it can prevent external oxygen from entering the fireproof cover while ensuring the discharge of gas.

[0018] 5. The utility model provides a drainage hole to facilitate the high-temperature water in the fireproof cover to flow out and lower the temperature. At the same time, it can reduce the pressure of water on the fireproof cover to prevent the fireproof cover from being expanded by water. In addition, combined with the setting of the installation height restriction, it can also ensure that the battery is completely immersed while preventing the car from becoming a water-soaked car.

[0019] 6. In the utility model, by setting a temperature sensor, the temperature value in the fireproof cover can be monitored in real time, which is convenient for controlling the on and off of the fire sprinkler, and the fire extinguishing situation can also be confirmed by the temperature change; by setting the fire extinguishing bomb, the fire can be suppressed when the temperature reaches the bursting temperature of the fire extinguishing bomb. Specifically, when the temperature is lower than the bursting temperature, the fire is only cooled and extinguished by the fire sprinkler. When the fire sprinkler cannot effectively suppress the fire, the temperature in the fireproof cover will continue to rise. When the bursting temperature of the fire extinguishing bomb is reached, the fire extinguishing bomb will burst. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The utility model provides a mobile intelligent fire extinguishing device for automobiles, such as Figures 1 to 3As shown, it includes a fireproof cover 1 and a fire sprinkler 2. The material of the fireproof cover 1 can be glass fiber silicone coated cloth. The bottom of the fireproof cover 1 is provided with an opening. The lower end of the fireproof cover 1 is provided with a lower fixing frame 3, and the upper end is provided with an upper fixing frame 4. The upper fixing frame 4 and the lower fixing frame 3 are both made of high temperature resistant metal materials. The fire sprinkler 2 is installed in the fireproof cover 1. The fire sprinkler 2 is connected to the water tank of the fire truck through a water pipe, and its control switch is located in the cab. The fire sprinkler 2 can be provided in plurality and can be installed on the top of the fireproof cover 1 and on the lower fixing frames 3 at the bottom of the left and right sides. When in use, the open fire above the car can be extinguished through the top fire sprinkler 2. The fire sprinklers 2 on both sides can directly extinguish the open flame on the battery. It also includes two lifting components 5 and a telescopic arm 6. The two lifting components 5 are arranged on both sides of the fireproof cover 1, and the bottom of the lifting component 5 is movably connected to the lower fixed frame 3, and the top is movably connected to the upper fixed frame 4. The fireproof cover 1 is driven by the two lifting components 5 to move down and fold on the lower fixed frame 3 or move up and unfold to form a closed space for placing the car. In order to improve the high temperature resistance, a hard fireproof board can be added to the top of the closed space, that is, the inner top of the fireproof cover 1. The telescopic arm 6 is located between the two lifting components 5, and the two ends of the telescopic arm 6 are respectively connected to the lower fixed frame 3 and the fire truck.

[0033] In this embodiment, the fireproof cover 1 can be combined with the fire truck by arranging the fireproof cover 1, the lifting assembly 5, the telescopic arm 6, the upper fixing frame 4 and the lower fixing frame 3. In addition, when a fire occurs, the fireproof cover 1 can be used to conveniently and quickly isolate the burning car from the surrounding cars or equipment to prevent the fire from spreading. In combination with the arrangement of the fire sprinkler 2, the open flame can be extinguished. At the same time, a water pool is formed in the fireproof cover 1 to immerse the battery, cool the battery, and isolate oxygen to achieve the ultimate purpose of fire extinguishing. Compared with the existing water gun fire extinguishing method, it can improve the fire extinguishing efficiency and greatly save water resources. At the same time, it can be operated at a long distance without any need for water spray. The fire-fighting personnel need to be close to each other, which greatly improves the safety performance. The specific process is that when a car catches fire, the fire truck moves to the vicinity of the burning car, and controls the telescopic arm 6 to extend and retract through the hydraulic system of the fire truck, and drives the fireproof cover 1 to cover the burning car. At the same time, the hydraulic system of the fire truck controls the two hydraulic rods 55 to extend synchronously, so that enough space is formed inside the fireproof cover 1, until the lower fixing frame 3 at the lower end of the fireproof cover 1 contacts the ground and forms a closed space. At this time, the fireproof cover 1 completely wraps the burning car, and the fire sprinkler 2 is manually opened to cool the inside of the fireproof cover 1 and extinguish the open fire, and accumulate water to form a pool of water to immerse the burning battery.

[0034] In the present invention, preferably, Figure 1 , Figure 2As shown, a sandbag circle 7 is further provided at the lower end of the fireproof cover 1.

In addition, the weight can be increased, and the fireproof cover 1 can be effectively prevented from being washed away by the water flow. By setting up the sandbag enclosure 7 on the side of the lower fixing frame 3 close to the car, and the bottom of the sandbag enclosure 7 is lower than the bottom of the lower fixing frame 3, the blocking of the lower fixing frame 3 and the gravity of the water itself can be utilized to further prevent the fireproof cover 1 from being washed away by the water flow. Specifically, at the beginning, the impact force of water on the sandbag enclosure 7 will be blocked by the lower fixing frame 3. As the amount of water increases, when the water level is higher than the sandbag enclosure 7, the water above the sandbag enclosure 7 will provide a downward force on the sandbag enclosure 7, and this force will increase as the amount of water increases.

[0036] In the present invention, preferably, Figure 1 , Figure 2 As shown, the fireproof cover 1 is also provided with an auxiliary support frame 12, which is sleeved on the outside of the fireproof cover 1 and is located between the lower fixing frame 3 and the upper fixing frame 4.
