Description

Technical Field

[0001] This utility model relates to the field of electric vehicle fire extinguishing technology, and in particular to a mobile, quick-assembly automatic sprinkler fire extinguishing device for electric vehicles. Background Technology

[0002] Currently, most electric vehicles are parked in parking lots or garages. Since most electric vehicles use lithium-ion batteries, when a battery cell overheats, it triggers a series of exothermic chemical reactions. If this heat cannot be dissipated in time, the battery temperature will rise rapidly, leading to thermal runaway. Thermal runaway in one battery cell can spread to adjacent cells, eventually causing the entire battery pack to catch fire, potentially igniting the undercarriage of the vehicle. This fire is difficult to extinguish because water spray cannot directly contact the fire source. Therefore, this type of fire extinguishing mechanism is designed to address such situations where fires are difficult to extinguish.

[0003] In existing technologies, some electric vehicle fire extinguishing mechanisms are typically of a fixed length. However, electric vehicles come in various models with different sizes, shapes, and battery layouts. When dealing with different models, it is necessary to replace the fire extinguishing mechanism with a different length and number of nozzles. This requires stockpiling multiple fire extinguishing mechanisms of different lengths and numbers of nozzles, which is extremely inconvenient to carry, increases procurement and storage costs, and reduces the flexibility of the fire extinguishing device. Therefore, to address the above shortcomings, a mobile and quick-assembly automatic sprinkler fire extinguishing device for electric vehicles is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mobile, quick-assembly automatic sprinkler fire extinguishing device for electric vehicles. This device aims to improve the existing technology, which requires the storage of multiple different fire extinguishing devices for different vehicle models, increasing procurement and storage costs and reducing the flexibility of fire extinguishing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile, quick-assembly type automatic sprinkler fire extinguishing device for electric vehicles, comprising two pipes and a water storage component for blocking water. A quick-connect water pipe plug is detachably connected to one side of each pipe. A nozzle is detachably connected to the left end of the left pipe. A water distributor is installed on the outside of the right pipe. A conversion assembly is detachably connected to the right end of the right pipe. A rotating quick connector is detachably connected to the right side of the conversion assembly. A water hose is fixedly connected to the right end of the rotating quick connector. A fire hydrant quick connector is fixedly connected to the right end of the water hose.

[0006] Furthermore, the water storage component includes a base plate, and a baffle plate is fixedly connected to the top of the base plate.

[0007] Furthermore, the adapter assembly can be configured as a standard quick-connect or a universal rotary connector.

[0008] This utility model has the following beneficial effects:

[0009] 1. In this utility model, the quick-connect plug for water pipes allows for pipe connection, enabling flexible assembly of pipe sections. Normally, the pipes can be stored in the box, and when in use, they can be quickly assembled using the quick-connect plug. The fire extinguishing device can be flexibly assembled with pipes and nozzles according to the size, shape, and battery layout of different electric vehicles, better adapting to the fire extinguishing needs of various vehicle models, improving the targeting and effectiveness of fire extinguishing, and thus increasing the overall flexibility of the device.

[0010] 2. In this utility model, the fire hose on the fire hydrant can be quickly connected via a quick-connect coupling, making location and water supply very convenient. A stable water supply can be obtained rapidly, significantly shortening preparation time and improving the timeliness of firefighting operations. During firefighting, placing a water deflector next to the vehicle prevents the sprayed water from flowing away, allowing for more efficient use of water resources for firefighting. The water can be submerged under the vehicle to achieve the purpose of extinguishing the fire. Attached Figure Description

[0015] 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.

[0016] Reference Figure 1 and Figure 2This utility model provides an embodiment of a mobile, quick-assembly automatic sprinkler fire extinguishing device for electric vehicles, comprising two pipes 1. These two pipes 1 are made of high-strength, corrosion-resistant materials to ensure a stable water flow during fire extinguishing. The surface of the pipes can be specially treated to have good wear resistance and impact resistance to adapt to various complex fire extinguishing environments. It also includes a water storage component for blocking water. Quick-connect water pipe plugs 2 are detachably connected to adjacent sides of the two pipes 1, enabling quick connection and disconnection between the pipes 1. A sprinkler head 5 is detachably connected to the left end of the left pipe 1, ensuring that the water flow effectively covers the fire source. A water distributor 3 is installed on the outside of the right pipe 1, which can precisely control the distribution of water flow to ensure that each pipe 1 receives sufficient water. The right end of the right-side pipe 1 is detachably connected to an adapter assembly 4. The adapter assembly 4 can be configured as a standard quick-connect fitting or a universal rotary joint. When the adapter assembly 4 is configured as a standard quick-connect fitting, the connection is quick and stable, suitable for situations where the baffle plate 10 is not required. It allows for a straight connection, quickly connecting the right-side pipe 1 to the rotary quick-connect fitting 6. When the baffle plate 10 is required, the adapter assembly 4 is configured as a universal rotary joint. This universal rotary joint offers high flexibility, allowing for curved connections, connecting from above the baffle plate 10.

[0017] The right side of the adapter assembly 4 is detachably connected to a rotating quick-connect fitting 6, which allows for multi-angle connections, facilitating the adjustment of the hose 7's position in different firefighting scenarios. The right end of the rotating quick-connect fitting 6 is fixedly connected to the hose 7, which can withstand significant water pressure, ensuring a stable water supply to the fire extinguishing device. The right end of the hose 7 is also fixedly connected to a fire hydrant quick connector 8, which quickly connects to the fire hose on the fire hydrant, providing a rapid and stable water supply, significantly reducing preparation time and improving the timeliness of firefighting operations. The water storage assembly includes a base plate 9, providing reliable support for the baffle plate 10. The top of the base plate 9 is fixedly connected to the baffle plate 10, which is of moderate height and effectively blocks water flow, preventing the sprayed water from flowing away and submerging the vehicle's chassis, thus making fuller use of water resources for firefighting and achieving efficient firefighting.

[0018] Working Principle: When faced with an electric vehicle fire, the required length and number of nozzles for the fire extinguishing device are first determined based on the specific size, shape, and battery layout of the electric vehicle. The segmented pipes 1 are retrieved from storage, and the various pipes 1 are quickly assembled and connected together using the quick-connect fittings 2. The nozzle 5 at the left end of the left pipe 1 is responsible for spraying water to extinguish the fire. The water distributor 3 on the outside of the right pipe 1 distributes the water flow, ensuring smooth water flow through the pipe. The adapter assembly 4 at the right end of the right pipe 1 is configured according to the actual situation. If the baffle 10 is not used, the adapter assembly 4 is set as a standard quick-connect fitting, allowing for a straight connection and quick connection of the right pipe 1 to the rotary quick-connect fitting 6. The water hose 7, fixedly connected to the right end of the rotary quick-connect fitting 6, is responsible for transporting water from a distance. The fire hydrant quick connector 8 at the right end of the water hose 7 can quickly connect to the fire hose on the fire hydrant, making location and water supply very convenient, thus quickly obtaining a stable water supply, significantly shortening preparation time and improving the timeliness of fire extinguishing operations. When the water deflector 10 is needed, the adapter assembly 4 is set as a universal swivel joint, which allows for a curved connection from above the water deflector 10. During firefighting, the base plate 9 of the water storage assembly is placed next to the car, and the water deflector 10 is erected, so that the water sprayed from the nozzle 5 will not flow away, and can submerge the car chassis, achieving the purpose of efficient firefighting.

[0019] 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.
