Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to an intelligent sprayable fireproof curtain device for new energy vehicles. Background Technology

[0002] With the transformation of the global energy structure and the increasing awareness of environmental protection, new energy vehicles, especially electric vehicles (EVs), are gradually becoming the mainstream means of transportation. Unlike traditional fuel vehicles, electric vehicles rely on power batteries for energy, and the improvement of charging infrastructure is a key factor in the widespread adoption of electric vehicles. Charging piles, as energy replenishment equipment for electric vehicles, function similarly to gas pumps at gas stations. They can be fixedly installed on the ground or walls and are widely used in public buildings (such as commercial buildings, shopping malls, public parking lots, etc.), residential parking lots, and dedicated charging stations.

[0003] However, with the surge in the number of electric vehicles, the vehicle density within charging stations is constantly increasing, leading to a growing fire safety risk. Fires involving new energy vehicles are typically caused by several main factors, including power battery failure, charging equipment malfunction, high temperatures, and improper operation. Currently, charging stations primarily rely on fire extinguishers, fire sprinkler systems, or manual firefighting measures to extinguish fires. However, traditional firefighting equipment suffers from shortcomings such as slow response times, insufficient localized fire suppression capabilities, and poor fire isolation capabilities.

[0004] To improve the fire safety of charging stations, there is an urgent need for a device that can respond quickly, extinguish fires accurately, and effectively isolate fire sources, so as to quickly control the fire when an electric vehicle fire occurs, prevent the fire from spreading further, and reduce casualties and property losses. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an intelligent sprayable fireproof curtain device for new energy vehicles, which addresses the above-mentioned deficiencies of the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A smart sprayable fireproof curtain device for new energy vehicles is constructed, including a canopy with multiple parking spaces under the canopy. It also includes an isolation device, a smoke detector, a spraying device, a support device, and a control device. The isolation device is fixed to the bottom of the canopy by the support device, and an isolation device is provided between two adjacent parking spaces.

[0008] The isolation device includes a crossbeam steel frame, a roller shutter tube, a drive motor, and a fireproof curtain. The roller shutter tube is rotatably connected to the bottom of the crossbeam steel frame. The fireproof curtain is wound around the roller shutter tube. The rotary motor is located on the outside of one end of the roller shutter tube and is used to drive the roller shutter tube to rotate. There are two smoke detectors, which are located on both sides of the crossbeam steel frame. The sprinkler device includes two water pipes located on both sides of the crossbeam steel frame and multiple sprinkler heads located on the water pipes. The water pipes are connected to a fire water source. The control device is used to receive signals from the smoke detectors and control the switching of the sprinkler heads and the rotation of the drive motor.

[0009] Preferably, the support device is a column fixed to the ground, one end of the crossbeam steel frame is fixed to the column with screws, and the other end is connected to the top of the column with a steel cable.

[0010] Preferably, the support device consists of two fixed plates fixed to the ceiling, and the two ends of the crossbeam steel frame are connected to the two fixed plates respectively through connecting rods.

[0011] Preferably, the bottom of the fireproof curtain is connected to a counterweight tube, and the counterweight tube has an adjustable counterweight block.

[0012] Preferably, it also includes magnetic strips and buffer devices installed on the ground, the positions of which correspond to the counterweight tube.

[0013] Preferably, the spray head is tilted downwards.

[0014] Preferably, the sprinkler head is an electrically adjustable sprinkler head, which includes a cooling sprinkler head and a fire extinguishing sprinkler head. The cooling sprinkler head uses fine water mist spraying, and the fire extinguishing sprinkler head uses high flow rate spraying.

[0015] Preferably, the crossbeam steel frame is provided with two support plates, and the two ends of the roller shutter tube are respectively rotatably connected to the two support plates, and the drive motor is mounted on either support plate.

[0016] Preferably, the water pipe is L-shaped, with the horizontal part of the L-shaped water pipe located on the crossbeam and the vertical part located on the column, and the control device is fixed to one side of the top of the column.

[0017] Preferably, the fixed plate is provided with an electric telescopic mechanism, the connecting rod is connected to the electric telescopic mechanism, and the electric telescopic mechanism is electrically connected to the control device.

[0018] The beneficial effects of this invention are as follows: During normal operation of the charging station, smoke detectors continuously monitor the air conditions between parking spaces. When a smoke detector detects an abnormal smoke concentration exceeding a set threshold, it immediately sends a fire signal to the control device. Upon receiving the alarm signal from the smoke detector, the control device starts the drive motor. The drive motor rotates the roller shutter, causing the fire curtain to fall between parking spaces, forming a physical isolation barrier to prevent the fire and dense smoke from spreading to adjacent parking spaces. Simultaneously, the control device sends a command to the sprinkler system to open the sprinkler heads on the water pipes. Fire water is sprayed through the water pipes to the area of ​​the burning vehicle, precisely extinguishing the fire. The sprinkler system continues to operate until the fire is effectively controlled. Based on the real-time monitoring data from the smoke detectors, the control device determines whether the fire is completely extinguished. When the smoke concentration returns to a safe range, the control device can send a command to stop the water spraying and simultaneously control the fire curtain to slowly roll back to the roller shutter, restoring the parking spaces to their normal state. If the fire continues or expands, the fire protection system can further link with external fire protection equipment, such as automatic alarms and smoke extraction systems, to enhance safety.

[0019] This invention utilizes smoke detectors to automatically detect fires, enabling a rapid response in the early stages of a fire, which is more efficient than manual detection and operation of fire extinguishers. The automatic sprinkler system directly targets the fire source, effectively reducing the risk of fire spread. The fire curtain automatically lowers during a fire, physically isolating the burning vehicle from surrounding vehicles, preventing the spread of flames and high temperatures to adjacent vehicles, thus reducing the risk of large-scale fires within charging stations. This device is suitable for high-density areas with concentrated new energy vehicles, such as charging stations, underground parking lots, and shopping mall parking areas, providing enhanced fire safety. The device is automatically controlled, reducing human intervention and improving the intelligence level of fire response. Traditional fire extinguishing methods rely on manual operation, while this device achieves automatic detection, automatic fire extinguishing, and automatic isolation, playing a greater role in sudden fires. Traditional fire sprinkler systems typically spray water over a large area, while this system uses precise localized spraying, effectively extinguishing only the point of ignition, reducing unnecessary water consumption, and avoiding water damage to vehicles and equipment in non-fire areas.

[0020] Therefore, the intelligent sprayable fireproof curtain device for new energy vehicles of this utility model can realize early detection, rapid isolation, precise fire extinguishing and intelligent control of fire, greatly improve the fire safety level of new energy vehicle charging stations and reduce property damage and personal injury.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The preferred embodiment of this utility model is an intelligent sprayable fireproof curtain device for new energy vehicles, such as... Figure 1 As shown, see reference Figure 2-3 The device includes a canopy with multiple parking spaces underneath. It is characterized by further including an isolation device 1, a smoke detector 2, a sprinkler device 3, a support device 4, and a control device 5. The isolation device 1 is fixed to the bottom of the canopy by the support device 4, and an isolation device 1 is provided between two adjacent parking spaces.

[0028] The isolation device 1 includes a crossbeam steel frame 11, a roller shutter tube 12, a drive motor 13, and a fireproof curtain 14. The roller shutter tube 12 is rotatably connected to the bottom of the crossbeam steel frame 11. The fireproof curtain 14 is wound around the roller shutter tube 12. The rotary motor is located on the outside of one end of the roller shutter tube 12 and is used to drive the roller shutter tube 12 to rotate. There are two smoke detectors 2, which are located on both sides of the crossbeam steel frame 11. The sprinkler device 3 includes two water pipes 31 located on both sides of the crossbeam steel frame 11 and multiple sprinkler heads 32 located on the water pipes 31. The water pipes 31 are connected to the fire water source. The control device 5 is used to receive the signal from the smoke detectors 2 and control the switching of the sprinkler heads 32 and the rotation of the drive motor 13.

[0029] During normal operation of the charging station, smoke detectors continuously monitor the air quality between parking spaces. When a smoke detector detects an abnormal smoke concentration exceeding a set threshold, it immediately sends a fire signal to the control device. Upon receiving the alarm signal, the control device activates the drive motor. The drive motor rotates the roller shutter, causing the fire curtain to descend between parking spaces, forming a physical barrier to prevent the fire and smoke from spreading to adjacent spaces. Simultaneously, the control device commands the sprinkler system to open the sprinkler heads on the water pipes. Fire water is sprayed through the pipes to the area of ​​the burning vehicle, precisely extinguishing the fire. The sprinkler system continues to operate until the fire is effectively controlled. Based on real-time monitoring data from the smoke detectors, the control device determines whether the fire is completely extinguished. When the smoke concentration returns to a safe range, the control device can send a command to stop the water spraying and simultaneously control the fire curtain to slowly retract back to the roller shutter, restoring the parking spaces to their normal state. If the fire continues or expands, the fire protection system can further link with external fire-fighting equipment, such as automatic alarms and smoke extraction systems, to enhance safety.

[0030] like Figure 1 As shown, the support device 4 is a column 41 fixed to the ground. One end of the crossbeam steel frame 11 is fixed to the column 41 with screws, and the other end is connected to the top of the column 41 with a steel cable. The support device (4) adopts a combination of column and steel cable to provide stronger support and make the crossbeam steel frame more stable. The column is fixed to the ground to ensure that the entire fire curtain system does not shake due to external forces (such as wind pressure and vibration), and improves the safety and durability of long-term use. By connecting one end of the crossbeam steel frame to the top of the column with a steel cable, the weight and tension borne by the crossbeam can be distributed, avoiding deformation or damage due to long-term stress, and improving the durability of the device. This design reduces the structural requirements of the crossbeam, which can reduce material costs while ensuring sufficient strength. The installation process is more convenient by using screw fixing + steel cable tensioning, and it is easier to adjust and maintain compared to a fully welded structure. Since the charging station may be located outdoors or in a semi-open environment, wind or ground vibration may affect the stability of the equipment. The steel cables connecting the top of the columns form a triangular mechanical support structure, which effectively disperses external impact forces, improves the wind and earthquake resistance of the entire device, and ensures that the fire curtain can still descend normally and isolate the fire source in an emergency. The column structure does not hinder the layout of the sprinkler system, while providing sufficient load-bearing capacity, making the entire fire curtain device more compact and aesthetically pleasing. It balances structural stability, ease of construction, and environmental adaptability, ensuring long-term reliable operation of the device in various environments and improving the safety and service life of new energy vehicle charging stations.

[0031] like Figure 2As shown, a counterweight tube 15 is connected to the bottom of the fire curtain 14. The counterweight tube 15 provides a certain weight, making the fire curtain more stable during descent and preventing it from swaying or shifting due to slight wind or airflow, thus ensuring that it accurately covers the fire source and forms an effective physical isolation barrier. The counterweight tube applies pressure to the bottom of the fire curtain, making it fit closer to the ground, reducing the bottom gap, effectively preventing the spread of dense smoke, toxic gases, and heat radiation, and improving fire control. Since the fire curtain is easily affected by external forces during ascent and descent, the extra weight of the counterweight tube makes it roll up more neatly, avoiding problems such as wrinkles and tangles, reducing wear on mechanical parts (such as the roller shutter tube), and increasing service life.

[0032] In this embodiment, a ground magnetic lock can be used to improve sealing performance. Specifically, a magnetic strip or electromagnetic lock can be installed on the ground. When the fire curtain is fully deployed, the counterweight tube can be magnetically fixed, ensuring a tight fit between the fire curtain and the ground, further enhancing smoke prevention and heat insulation effects. Simultaneously, a sprinkler pipe or foam extinguishing device can be integrated inside the counterweight tube. When the fire curtain is deployed, extinguishing liquid can be sprayed simultaneously from the bottom, improving extinguishing efficiency, especially suitable for fires caused by battery thermal runaway.

[0033] Install buffer devices (such as rubber pads) at both ends of the counterweight tube or on the ground to reduce the impact force when the fire curtain lands, extend the equipment life, and reduce noise interference. The counterweight tube can have adjustable counterweight blocks to dynamically adjust the weight according to the length, material, or wind conditions of the fire curtain, ensuring the best drooping effect and making it suitable for charging stations in different scenarios.

[0034] like Figure 1-2 As shown, the sprinkler head 32 is tilted downwards. The downward tilt of the sprinkler head (32) allows for precise spraying of the extinguishing water towards the fire source, rather than horizontal diffusion or ineffective spraying. This ensures that the water flow can quickly soak the surface of the burning vehicle and the battery pack area, improving the fire extinguishing effect, especially providing better cooling for thermal runaway fires involving electric vehicle power batteries. The downward tilt arrangement concentrates the water flow, reducing waste of extinguishing fluid, improving the utilization rate of the fire extinguishing system, and simultaneously reducing the amount of water on the ground, minimizing secondary damage. The tilted spray helps form an efficient water curtain, blocking the spread of flames and heat radiation to adjacent parking spaces, further enhancing the fire isolation effect. Combined with the physical isolation effect of the fire curtain, it can effectively control the spread of fire and improve the safety of new energy vehicle charging stations.

[0035] In this embodiment, the sprinkler head can be electrically or mechanically adjustable in spray angle, dynamically adjusting the spray direction according to the location of the fire source and the combustion situation to improve the accuracy of fire extinguishing. Furthermore, a dual-mode sprinkler head (cooling sprinkler head + fire extinguishing sprinkler head) can be used, combining a fine water mist mode (cooling sprinkler head) and a high-flow-rate spray mode (fire extinguishing sprinkler head) to achieve staged fire extinguishing and improve safety. Different sprinkler heads (cooling sprinkler head + fire extinguishing sprinkler head) can be set at each adjacent sprinkler location, or a switchable sprinkler head can be set at each sprinkler location. When using the former, the control device first controls the fire extinguishing sprinkler head to spray at a high flow rate for fire extinguishing. After fire extinguishing, the fire extinguishing sprinkler head is closed, and the cooling sprinkler head sprays fine water mist to cool the flames and prevent reignition. If the latter is used, after fire extinguishing, the sprinkler head is switched via a switching valve (specifically a ball valve, which can close two sprinkler heads or open one of them) to cool the flames using the cooling sprinkler head.

[0036] like Figure 1-2 As shown, the crossbeam steel frame 11 is provided with two support plates 15, and the two ends of the roller shutter tube 12 are respectively rotatably connected to the two support plates 15. The drive motor 13 is set on any of the support plates.

[0037] like Figure 1-2 As shown, the water pipe 31 is L-shaped, with the horizontal part of the L-shaped water pipe 31 located on the crossbeam and the vertical part located on the column 41. The control device 5 is fixed to one side of the top of the column 41. The horizontal part of the water pipe and the vertical part of the water pipe are connected by elbows.

[0038] Another preferred embodiment of this utility model is, for example... Figure 4 As shown, the difference between this embodiment and the previous embodiment is that the support device 4 consists of two fixed plates 42 fixed on the ceiling, and the two ends of the crossbeam steel frame 11 are connected to the two fixed plates 42 respectively through connecting rods.

[0039] Two fixed plates secure the two ends of the crossbeam steel frame to the ceiling, reducing the space occupied by the frame compared to column support, while improving the overall structural stability. The ceiling-fixed method effectively reduces the impact of external forces (such as wind pressure and vibration) on the crossbeam steel frame, making it particularly suitable for locations with strong seismic or vibration environments, such as high-rise parking lots and underground parking lots. Since the two fixed plates are suspended from the ceiling, there is no need for columns on the ground, avoiding the occupation of parking spaces or charging areas, making vehicle entry and exit smoother, and improving the space utilization of the charging station. It is suitable for narrow charging areas or high-traffic parking lots, preventing the support structure from blocking parking spaces, affecting charging operations, or facilitating personnel evacuation in emergencies. It is particularly suitable for locations with complex ground conditions or where columns cannot be installed, such as underground parking lots, concrete floors, or areas with existing paved tiles, without damaging the ground structure, reducing installation costs and construction difficulty. The two fixed plates can be designed with adjustable lengths to adapt to ceilings of different heights, improving installation flexibility. Ground-mounted columns may be deformed or damaged by external impacts (such as vehicle collisions or daily wear and tear), while the two fixed plates (42) suspended installation avoids these problems and improves the durability of the device. During equipment maintenance, there is no need to disassemble the ground structure; only adjustments or replacements are required at the ceiling, reducing maintenance difficulty. The ceiling-fixed + rod-suspended method allows the fire curtain to form a more uniform and tighter fire barrier when lowered, reducing side gaps and preventing smoke diffusion.

[0040] An electric telescopic mechanism can be integrated into the two fixed plates. This mechanism connects to a connecting rod, allowing for height adjustment of the isolation device. The position of the fire curtain can be adjusted according to vehicle height or fire conditions in different environments, improving adaptability. Additionally, buffer springs or damping devices are added to the two fixed plates to enhance seismic performance, making it suitable for high-rise buildings or earthquake-prone areas, preventing damage or misalignment of the crossbeams due to structural vibrations.

[0041] In summary, the support device uses two fixed plates to fix it to the ceiling, which makes the structure more stable, reduces the ground space occupation, lowers maintenance costs, and improves the sealing and fire safety of the fire curtain. At the same time, it can be expanded by combining intelligent adjustment, shock absorption, modular design and other technologies to further improve adaptability and service life.

[0042] This invention utilizes smoke detectors to automatically detect fires, enabling the system to respond rapidly in the early stages of a fire, making it more efficient than manual detection and operation of fire extinguishers. The automatic sprinkler system directly targets the fire source, effectively reducing the risk of fire spread. The fire curtain automatically lowers during a fire, physically isolating the burning vehicle from surrounding vehicles, preventing the spread of flames and high temperatures to adjacent vehicles, thus reducing the risk of large-scale fires within charging stations. This device is suitable for high-density areas with concentrated new energy vehicles, such as charging stations, underground parking lots, and shopping mall parking areas, providing enhanced fire safety. The device is automatically controlled, reducing manual intervention and improving the intelligence level of fire response. Traditional fire extinguishing methods rely on manual operation, while this device achieves automatic detection, automatic fire extinguishing, and automatic isolation, playing a greater role in sudden fires. Traditional fire sprinkler systems typically spray water over a large area, while this invention uses localized, precise spraying, effectively extinguishing only the point of ignition, reducing unnecessary water consumption, and avoiding water damage to vehicles and equipment in non-fired areas.

[0043] Therefore, the intelligent sprayable fireproof curtain device for new energy vehicles of this utility model can realize early detection, rapid isolation, precise fire extinguishing and intelligent control of fire, greatly improve the fire safety level of new energy vehicle charging stations and reduce property damage and personal injury.

[0044] It should be understood that this utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
