Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle fire prevention and control, and specifically relates to an isolation device for automobile fires. Background Technology

[0002] Traditional vehicle fire prevention technologies commonly employ methods such as vehicle-mounted fire extinguishers, automatic sprinkler systems, and fire blankets. However, these methods have significant limitations: vehicle-mounted fire extinguishers have limited capacity and are only suitable for small initial fires, making it difficult to control large-scale fires; automatic sprinkler systems typically rely on fixed installations and cannot flexibly respond to fires involving moving vehicles; and while fire blankets can provide localized flame retardancy, their coverage area is limited, and they lack effective flame guiding and cooling mechanisms, making them difficult to operate in parking lots and hindering the spread of fire.

[0003] Furthermore, existing technologies generally lack rapid deployment capabilities, making it difficult to quickly establish effective isolation in emergencies, thus increasing the risk of fire spread. Especially in high-temperature, rapidly spreading fire scenarios such as electric vehicle battery fires, traditional methods often fail to provide sufficient heat insulation and fire extinguishing effectiveness, posing significant safety hazards.

[0004] To address the aforementioned issues, this patent proposes a vehicle fire prevention and control device that can respond quickly, isolate efficiently, and also has fire extinguishing capabilities. When a car catches fire, this device can be quickly moved to cover the burning vehicle, achieving precise fire control. Multiple products of this patent can also be used to cover unburned vehicles in the flame propagation path, blocking the flame spread path and achieving the effect of fire isolation, thereby overcoming the shortcomings of existing vehicle fire prevention and control technologies. Utility Model Content

[0005] The purpose of this invention is to provide an isolation device for automobile fires, in order to solve the problem mentioned in the background art that traditional vehicle fire prevention and control lacks rapid deployment capabilities and is difficult to quickly form an effective isolation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an isolation device for automobile fires, comprising a fixed frame, with multiple movable display stands arranged on the outside of the fixed frame, and the interior of each movable display stand being hollow. Locking wheels are fixedly connected to the two rear corners of the lower end of the fixed frame, and the locking wheels are composed of locking locks and swivel wheels. Moving wheels are arranged at the two front corners of the lower end of the fixed frame. The fixed frame and the multiple movable display stands are covered with fireproof covers.

[0007] Preferably, the fireproof cover is made of ceramic fiber cotton, and creases are provided between the fixed frame and the movable display frame, as well as between two adjacent movable display frames.

[0008] Preferably, the fireproof cover has multiple guide holes on its top, and the upper left and right sides of the movable wheel are fixedly connected to limit frames, with a limit shaft fixedly connected between the two limit frames.

[0009] Preferably, the limiting shaft passes through the fixed frame and multiple movable display stands, and both the fixed frame and the movable display stands rotate around the limiting shaft. Limiting pins are provided at both the left and right ends of the fixed frame and the movable display stands.

[0010] Preferably, all of the limiting pins pass through the inside of the limiting shaft, and all of the movable display frames located between the fixed frame and the outermost movable display frame have multiple fire extinguishing nozzles connected to the inner wall of the end away from the limiting shaft.

[0012] Compared with the prior art, this utility model provides an isolation device for automobile fires, which has the following beneficial effects:

[0013] 1. This utility model adopts a combination design of a fixed frame and multiple sets of movable display racks. Through a linkage mechanism, it can be quickly unfolded and folded, thereby unfolding the fireproof cover into a semi-cylindrical isolation space to isolate the burning vehicle. The semi-cylindrical fireproof cover has a stable structure, a large coverage area, and can adapt to different vehicle sizes. It is also easy to store and reuse. The fireproof cover is made of ceramic fiber cotton material, which has excellent high temperature resistance and can effectively block flames and high temperatures, prevent the fire from spreading out of the device or prevent external flames from igniting the vehicle inside the device. The device forms a fire isolation wall, thereby blocking the path of fire spread.

[0014] 2. The fireproof cover of this utility model has a guide hole on the top, which uses the chimney effect to guide the flames and high-temperature airflow upward, reducing the risk of lateral spread. At the same time, it is combined with the fire extinguishing nozzle integrated inside the movable display stand to spray, thereby accurately extinguishing the fire on the burning vehicle and quickly cooling it down.

[0015] 3. The nozzle of this utility model faces the high-temperature area at the top of the fireproof cover, which not only improves the fire extinguishing efficiency and safety, but also reduces the impact of heat radiation from the surrounding environment, prevents flames from accumulating in the confined space, and enhances fire control capabilities.

[0016] 4. The fireproof cover of this utility model has creases between the fixed frame and the display frame, which can be quickly folded and stored. At the same time, the bottom of the device is equipped with lockable casters and movable wheels, which can be quickly deployed to the fire scene and kept stable by the locking mechanism. This not only improves the emergency response speed, but also ensures that it can be quickly deployed and fixed in place when a fire occurs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-6The illustrated isolation device for vehicle fires includes a fixed frame 1, with multiple movable display stands 2 externally mounted on the fixed frame 1. Each movable display stand 2 is hollow internally. Locking wheels 3, consisting of locking locks and swivel wheels, are fixedly connected to the two rear corners of the lower end of the fixed frame 1. Movable wheels 4 are located at the two front corners of the lower end of the fixed frame 1. The fixed frame 1 and the multiple movable display stands 2 are covered by a fireproof cover 5 made of ceramic fiber cotton. In the event of a vehicle fire, the fireproof cover 5 is activated by two locking wheels... Wheel 3 and two movable wheels 4 push the fire isolation device to the fire scene, and push the fixed frame 1 and multiple movable display frames 2 to the outside of the vehicle. Then, the locking wheel 3 is locked to the universal wheel of the locking wheel 3 by the locking lock, so that the fire isolation device is fixed to the outside of the vehicle. Then, the fireproof cover 5 is unfolded by multiple movable display frames 2, so that the fireproof cover 5 completely wraps the vehicle inside. Since the fireproof cover 5 is made of ceramic fiber cotton, it has a good heat insulation effect, thereby isolating the vehicle where the fire occurs and preventing the fire from spreading.

[0026] Furthermore, the top of the fireproof cover 5 is provided with multiple guide holes 6. The upper left and right sides of the moving wheels 4 are fixedly connected to limit frames 7. The two limit frames 7 are fixedly connected to a limit shaft 8. The limit shaft 8 passes through the inside of the fixed frame 1 and multiple movable display frames 2. The left and right ends of the fixed frame 1 and the movable display frames 2 are provided with limit pins 9. The multiple limit pins 9 all pass through the inside of the limit shaft 8. During the unfolding of the fireproof cover 5, since the fixed frame 1 and the multiple movable display frames 2 are connected to each other through the two limit shafts 8 on both sides, and the position between them and the two limit shafts 8 is restricted by the multiple limit pins 9, and the fixed frame 1 and the movable display frames 2 rotate around the limit shaft 8, the fixed frame 1 and the movable display frames 2 can unfold the fireproof cover 5 into a semi-cylindrical shape, so that there is enough space inside the fireproof cover 5 to wrap the vehicle inside, and the flames and high temperatures are guided to the top of the fireproof cover 5 through the cylindrical inner wall, and then guided and discharged through the multiple guide holes 6 to prevent the fire from spreading to the outside.

[0027] Among them, multiple fire extinguishing nozzles 10 are connected to the inner wall of the multiple movable display frames 2 located between the fixed frame 1 and the outermost movable display frame 2, away from the limiting shaft 8. The opening direction of the multiple fire extinguishing nozzles 10 is pointing towards the limiting shaft 8. The left end of the multiple movable display frames 2 located between the fixed frame 1 and the outermost movable display frame 2, near the limiting shaft 8, is connected to the connecting pipe head 11, and the multiple connecting pipe heads 11 are connected to the external water pipe. When the fireproof cover 5 completely covers the vehicle, the flames and high temperature are guided to the top of the fireproof cover 5 through the multiple connecting pipe heads 11. Since the multiple fire extinguishing nozzles 10 are located on the upper side of the fireproof cover 5 after the fireproof cover 5 is unfolded, and are connected to the external water pipe through the multiple hollow movable display frames 2 and the multiple connecting pipe heads 11, the multiple fire extinguishing nozzles 10 can spray water into the fireproof cover 5 and extinguish the flames guided to the top of the fireproof cover 5 through the sprayed water, cool down the high temperature, and thus quickly control the fire.

[0028] In addition, after the fire is extinguished, the fireproof cover 5 is retracted again using multiple movable display stands 2. Since the fireproof cover 5 has creases between the fixed frame 1 and the movable display stand 2, as well as between two adjacent movable display stands 2, the fireproof cover 5 can be easily folded between the fixed frame 1 and the movable display stand 2, as well as between two adjacent movable display stands 2. This prevents the fireproof cover 5 from being too thick or too hard to fold, thereby improving the efficiency of the fire isolation device in unfolding and retracting, and ensuring a rapid response when a vehicle fire occurs.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
