Description

Technical Field

[0001] This utility model belongs to the technical field of fire extinguishing equipment, and specifically relates to a wall-mounted rapid fire extinguishing device for new energy vehicles. Background Technology

[0002] As a crucial component of green transportation, new energy vehicles' lithium-ion battery systems are characterized by rapid ignition, high combustion temperatures, and a significant risk of reignition during thermal runaway. Traditional fire extinguishing methods face multiple technical bottlenecks: conventional fire blankets, lacking a rigid support structure, are easily lifted by the high-pressure gas generated by battery thermal runaway, leading to extinguishing failure; fire hoses have blind spots, making it difficult to achieve rapid, three-dimensional fire suppression; open sprinkler systems consume large amounts of water, easily causing secondary flooding in enclosed spaces such as underground parking lots. Existing technologies, such as coverage-type fire extinguishing devices, generally suffer from poor structural stability, low extinguishing efficiency, and insufficient water resource utilization, failing to meet the unique fire extinguishing needs of new energy vehicles. Furthermore, existing devices lack adaptability to different parking scenarios, making rapid deployment difficult in narrow parking spaces or concentrated parking areas. How to construct a dedicated fire extinguishing system for new energy vehicles in parking spaces that combines rapid response, comprehensive coverage, and efficient water resource utilization has become a pressing technical challenge in this field. Utility Model Content

[0003] This utility model provides a wall-mounted rapid fire extinguishing device for new energy vehicles, which can quickly form a closed fire extinguishing space, improve fire extinguishing efficiency through immersion fire extinguishing, prevent battery reignition, and is particularly suitable for fire extinguishing problems of cars in parking lots.

[0004] A wall-mounted rapid fire extinguishing device for new energy vehicles includes a rotating and telescopic fire extinguishing hood. The hood comprises a U-shaped fire extinguishing hood with two or more U-shaped frames featuring hollow pipe structures. These frames connect to fire sprinklers and fire water connectors. The outermost edge of the U-shaped frame connects to the wall of the parking space. The outer perimeter of the U-shaped frame is covered with flame-retardant fabric. A water-blocking barrier surrounds the bottom of the fire extinguishing hood, allowing water from the fire sprinklers to accumulate between the barrier and the vehicle, forming a pool that immerses the vehicle. This wall-mounted rapid fire extinguishing device utilizes the U-shaped frame at the outermost edge of the fire extinguishing hood to achieve fixed-position, continuous fire prevention. For new energy vehicles in the corresponding parking spaces, a rapid and effective fire extinguishing method can be achieved through a rotating and pulling mechanism, providing comprehensive water extinguishing, air isolation extinguishing, and immersion extinguishing. Furthermore, it has minimal impact on the surrounding environment, avoiding secondary disasters.

[0005] The U-shaped frame is provided with a first water inlet at both ends. The first water inlet is connected to the hinge through a connecting pipe with a water inlet interface. The first U-shaped frame on the side of the hinge that contacts the ground is connected to a fire water connector. The outer pipe of the first U-shaped frame is connected to the first U-shaped water barrier, and the inner pipe of the first U-shaped frame is connected to the second U-shaped water barrier. The hinge connects two or more U-shaped frames and they are interconnected through pipes.

[0006] The U-shaped fire extinguishing cover has a folded state and an unfolded state. In the folded state, two or more U-shaped frames are attached to the wall. In the unfolded state, two or more U-shaped frames, together with the outer flame-retardant fabric, surround each other to form a closed semi-circular structure around the new energy vehicle and the top of the new energy vehicle.

[0007] The flame-retardant fabric has a pressure relief skylight on its side, and a cover curtain is provided on the outside of the pressure relief skylight.

[0008] A cylinder is connected between the outermost U-shaped frame and the first U-shaped frame. The cylinder controls the retracted or extended state of the U-shaped fire extinguishing cover.

[0009] The U-shaped skeletons of the two or more hollow pipe structures can rotate a maximum of 90 degrees relative to each other.

[0010] As can be seen from the above, the wall-mounted rapid fire extinguishing device for new energy vehicles provided in this application forms a three-dimensional water curtain by connecting fire nozzles through a hollow pipe frame, and the bottom water-blocking fence accumulates fire water to form a soaking water pool, which quickly covers the new energy vehicle and establishes a closed fire extinguishing space. It has the advantages of suppressing battery thermal runaway, preventing reignition, and improving water resource utilization. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-4 The specific implementation method further illustrates the technical solution of this patent.

[0017] In existing technologies, fires caused by battery thermal runaway in new energy vehicles are characterized by rapid spread and a high risk of reignition. Traditional fire blankets are easily lifted by expanding gases in high-temperature environments, leading to insulation failure. Fire hoses are limited by their spray angle, making it difficult to cover the underside of the vehicle and concealed fire sources inside. Excessive water usage not only affects the structural safety of underground spaces but also causes secondary damage to surrounding vehicles. In one instance, an electric vehicle spontaneously combusted in an underground parking lot; because conventional firefighting equipment could not effectively control the fire vertically across the battery pack, several adjacent vehicles were damaged.

[0018] To address these issues, the R&D team recognized that fire control required simultaneous fulfillment of three requirements: three-dimensional coverage, continuous cooling, and water volume control. Initial attempts involved integrating a sprinkler system within the fire blanket, but the flexible material was found to easily deform and collapse at high temperatures. The team then shifted its design focus to combining a rigid support structure with a flexible flame-retardant layer. By analyzing the thermal airflow patterns during vehicle combustion, a pressure balancing mechanism was proposed at the top of the covering device to prevent internal pressure buildup. To address the issue of secondary reignition, an adjustable-height water-filled enclosure system was introduced to immerse the vehicle in water for fire suppression, primarily targeting the battery. This rapid cooling prevents deflagration and quickly controls the fire.

[0019] Therefore, this application proposes a wall-mounted rapid fire extinguishing device for new energy vehicles, including a U-shaped fire extinguishing cover that can rotate up to 90 degrees between each other. The U-shaped fire extinguishing cover includes two or more U-shaped frames 23 with hollow pipe structures. Both ends of the U-shaped frame 23 are provided with water inlets. The water inlets are connected to hinges 17 through connecting pipes with water inlet interfaces 25. The first U-shaped frame on the side of the hinge 17 in contact with the ground is connected to a fire water connector 19. The outer pipe of the first U-shaped frame is connected to a first U-shaped water-blocking fence 18, and the inner pipe of the first U-shaped frame is connected to a second U-shaped water-blocking fence 22. The water-blocking fence is composed of a water-filled rubber barrier, forming a ring-shaped water-retaining wall after being filled with water. The hinge 17 connects two or more U-shaped frames 23 to each other through pipes, and the outermost U-shaped frame 23 is connected to the wall 14 of the parking space.

[0020] The U-shaped frame refers to a U-shaped support structure made of hollow pipes, which can be made of aluminum alloy or carbon fiber. It transports fire water through internal channels to form a sprinkler system. The inlets are fluid entrances located at both ends of the frame, connecting to an external water source via connecting pipes for rapid water supply. The hinges are rotating connecting components, made of high-temperature resistant metal, that control the rotation, expansion, and contraction of the U-shaped frame. The first and second U-shaped water-blocking barriers are flexible water-blocking structures located on the outer and inner sides of the frame, respectively, used to prevent water spread and create a water storage area during firefighting. The wall connection structure refers to the installation method of fixing the edge frame to the parking space wall using bolts or clips, ensuring the stability and ease of use of the fire extinguishing device when deployed, enabling rapid firefighting of cars in the parking space.

[0021] Specifically, when a fire occurs in a new energy vehicle, the U-shaped fire extinguishing cover unfolds from the wall, with multiple U-shaped frames rotating to form a semi-circular enclosure covering the vehicle. Firefighting water enters the internal pipes of the frame through inlets and is sprayed evenly onto the vehicle surface from the nozzles. The outer first U-shaped water-blocking barrier and the inner second U-shaped water-blocking barrier work together to form a ring-shaped water storage area around the vehicle, continuously immersing the bottom of the vehicle. The U-shaped frames along the edges are supported by wall anchor points, ensuring the stability of the structure after unfolding. The interconnected pipe design between the multiple frames allows the water flow to be evenly distributed to each nozzle, avoiding insufficient water supply in localized areas.

[0022] Through the above technical solutions, this application can realize rapid three-dimensional fire fighting of new energy vehicles. The rotating and unfolding structure adapts to narrow parking spaces. The water storage fence design controls the range of water stains while ensuring the fire fighting effect. The pipe-connected skeleton system takes into account both structural strength and water flow distribution efficiency. The wall fixing method improves the impact resistance and stability of the U-shaped skeleton after unfolding. It can be reused.

[0023] This application further proposes that the U-shaped fire extinguishing cover is divided into a folded state and an unfolded state. In the folded state, two or more U-shaped frames 23 are attached to the wall 14. In the unfolded state, two or more U-shaped frames 23, together with the outer flame-retardant fabric 15, surround each other to form a closed semi-circular structure around the new energy vehicle 8 and the top of the new energy vehicle 8. The flame-retardant fabric 15 has a skylight 20 on the side and a cover curtain 21 on the outside of the skylight 20.

[0024] The U-shaped frame refers to a U-shaped support structure made of hollow pipes, which can be made of aluminum alloy or carbon fiber. The flame-retardant fabric is a fireproof material covering the outside of the frame, used to isolate flames and guide water flow. The skylight is a ventilation opening on the side of the flame-retardant fabric, used to balance internal air pressure. The skylight cover is a flexible curtain covering the outside of the skylight, used to regulate ventilation. The wall connection refers to fixing the outermost U-shaped frame to the parking space wall, which can be achieved using expansion bolts or welded brackets, ensuring controllable deployment direction.

[0025] Specifically, when a fire occurs in a new energy vehicle, the U-shaped fire extinguishing cover switches from a retracted state to an extended state. Multiple U-shaped frames extend outwards, causing the flame-retardant fabric to form a semi-circular enveloping structure. The flame-retardant fabric completely covers the top and sides of the vehicle, while the bottom is protected by a water-resistant barrier to collect fire-fighting water and create a soaking environment. After the sunroof is extended, its opening and closing can be adjusted using a cover curtain, which can both release high-temperature gases to prevent excessive internal pressure and maintain the airtightness required for fire suppression.

[0026] Compared to existing technologies, traditional fire blankets are easily blown away by fire due to the lack of a fixed support structure and cannot form a three-dimensional enclosure. This solution, however, achieves all-round coverage of the vehicle through wall anchoring and frame linkage. In existing technologies, direct spraying of fire-fighting water can easily lead to blind spots due to angle limitations. This solution, through a semi-enclosed structure combined with bottom water storage, ensures that the water flow evenly covers the vehicle body, reducing fire-fighting blind spots.

[0027] Through the above technical solution, this application solves the problems of inadequate coverage and high-temperature gas lifting the fire extinguishing device during the fire extinguishing process of new energy vehicles. It quickly forms a three-dimensional isolation space through a semi-enclosed structure, and effectively inhibits reignition by water immersion. At the same time, the wall-fixed design improves the reliability of device deployment and reduces external environmental interference.

[0028] This application further proposes that a cylinder 16 is connected between the outermost U-shaped frame 23 and the first U-shaped frame, and the cylinder 16 controls the retracted or extended state of the U-shaped fire extinguishing cover. A cylinder is a linear actuator that drives the movement of the U-shaped fire extinguishing cover, such as a telescopic cylinder driven by pneumatic or hydraulic pressure, and the extension range of the frame is adjusted by controlling the extension length of the cylinder.

[0029] Specifically, in its folded state, the U-shaped fire extinguishing hood has multiple U-shaped frames that fit against the wall to minimize space occupation. When fire extinguishing is triggered, a cylinder pushes the U-shaped frames outward, forming a semi-circular enclosure around the new energy vehicle. During this process, fire-fighting water is introduced into the hollow pipe through the inlet via a connecting pipe. The water flows through the first and second U-shaped water-blocking barriers to form a water storage barrier, while the nozzles spray the extinguishing agent onto the vehicle from inside the frame. The wall connection design ensures the stability of the unfolded frame, preventing structural displacement due to water flow impact or high temperatures.

[0030] Compared to existing technologies, current fire extinguishing devices mostly rely on manual deployment of fire extinguishing covers. Their deployment speed is limited by the operator's reaction time, and they lack fixed support, making them susceptible to being washed away by water flow. This solution achieves automated deployment through cylinder drive, and the wall-mounted fixing method significantly improves structural stability. Furthermore, the hollow frame combined with the water-blocking barrier allows for precise control of the water storage area, reducing the impact of fire water diffusion on the surrounding environment.

[0031] Through the above technical solution, this application solves the problems of low deployment efficiency and poor stability of traditional fire extinguishing covers. By mechanically driving and fixing it to the wall, it ensures that the fire extinguishing cover can quickly form a closed fire extinguishing space under high temperature or water flow impact, reducing the risk of reignition and reducing water waste.

[0032] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
