Description

Technical Field

[0001] The present invention relates to the technical field of parking space fireproof curtains, and in particular to an automatic fireproof curtain device dedicated to new energy parking spaces. Background Art

[0002] Fire and spontaneous combustion issues in new energy vehicles (EVs) have attracted widespread attention, especially as they become more popular in the market. Most new energy vehicles use lithium-ion batteries. This type of battery has a high energy density, but if the battery is short-circuited, overcharged, over-discharged, or physically damaged, it may lead to a "thermal runaway" phenomenon, where the battery temperature rises sharply and eventually causes a fire. The battery management system (BMS) is responsible for monitoring and controlling the charge and discharge status of the battery. If the BMS fails, it may not be able to detect the abnormal state of the battery in time, causing the battery to overheat or short-circuit, which in turn causes spontaneous combustion. The battery pack may be damaged in a traffic accident or when the vehicle is hit by an external force. Lithium-ion batteries are very sensitive to physical damage, and if the internal structure of the battery is damaged, it may cause a short circuit and spontaneous combustion. Extreme ambient temperatures (such as high temperatures) increase the risk of battery spontaneous combustion.

[0003] The role of fire curtains on parking spaces is to provide a fire barrier, which is mainly used to delay the spread of fire and block the spread of flames and toxic fumes in the event of a fire. In particular, in the case of fires caused by new energy vehicles (such as electric vehicles) due to battery thermal runaway and other reasons, fire curtains can help protect surrounding vehicles and buildings. When a vehicle spontaneously ignites or catches fire, the fire curtain can be quickly deployed to form a barrier to prevent the flames from spreading to the surrounding area. This is particularly important for underground parking lots or dense parking lots, because the space between parking spaces is usually small and the fire can easily spread from one vehicle to other vehicles. Fire curtains can help suppress the high temperature of the fire and prevent the flames from directly contacting the surrounding vehicles or structures, thereby reducing the heat radiation damage caused by the fire and protecting the surfaces of neighboring vehicles and buildings. When a fire occurs, especially a fire in an electric vehicle battery, a large amount of toxic gases may be produced. Fire curtains can effectively block and delay the spread of these toxic fumes, providing valuable time for personnel evacuation and firefighters to rescue, and reducing the harm of smoke to the human body.

[0004] Fire curtains play a key role in protecting surrounding vehicles and buildings, slowing the spread of fire, reducing smoke diffusion and providing rescue time. It is an effective fire safety measure, especially suitable for confined spaces such as underground garages or large parking lots, helping to reduce the damage caused by fire risks.

[0005] During the spontaneous combustion of new energy vehicles, the chemical reaction in the battery may be accelerated, thereby increasing the risk of fire. Unqualified charging equipment or improper charging operations, especially long-term overcharging, may cause the battery temperature to be too high, thereby increasing the risk of fire in underground garages or other new energy vehicle parking spaces.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs an automatic fire protection curtain device dedicated to new energy parking spaces to solve the above technical problems. Summary of the invention

[0007] The technical purpose to be achieved by the present invention is to design an automatic fire protection curtain device specially used for new energy parking spaces. When a new energy vehicle spontaneously ignites due to charging or high outdoor temperature, an isolation zone is quickly formed, and the zone is covered with fire sand and continuously cooled by water spraying, thereby minimizing the loss.

[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0009] The automatic fire curtain device for new energy parking spaces is designed to effectively improve the safety of new energy vehicles in parking spaces. With the popularity of new energy vehicles, the risk of spontaneous combustion of electric vehicles due to battery problems has attracted widespread attention. Therefore, how to take quick measures to prevent the spread of fire when a fire occurs has become an important research topic.

[0010] The application parking space is designed as a standard parking space to meet common parking needs. Support columns are set at the four corners of the parking space to support the entire fire protection device. In the application scenario of the underground garage, the support columns can use the existing load-bearing beams, which not only saves installation costs but also reduces the occupation of underground space. In the ground parking lot, the additional steel structure support columns can provide the necessary stability and support. In addition, the existing charging piles can also be transformed into part of the support column, so that the fire protection device and the charging facilities can be integrated into the design and improve the efficiency of space utilization.

[0011] In addition to the basic supporting structure, the automatic fire curtain device also includes multiple functional components, namely, the isolation mechanism, the fire extinguishing mechanism, the water inlet pipe, the switch component and the rotating component. The coordinated work of these components can quickly respond to the fire and effectively contain the fire.

[0012] First of all, the isolation mechanism is an important part of the device and is fixedly installed between the support columns. The isolation mechanism is in the shape of a long strip, and four isolation mechanisms together form a rectangular frame that surrounds the parking space. When a fire occurs, the electromagnetic block in the isolation mechanism is energized, and the control block automatically opens, so that the internal rotating assembly is released. After losing the control of the isolation mechanism, the gravity ball in the rotating assembly will fall naturally, driving the curtain to unfold quickly, isolating the parking space from the external environment. This design can effectively prevent flames and toxic smoke from spreading to surrounding vehicles or buildings, buying time for fire extinguishing and protecting the surrounding environment.

[0013] Secondly, the fire extinguishing mechanism is the core fire extinguishing equipment of the entire device, which is installed in the middle part of the isolation mechanism. The interior of the fire extinguishing mechanism is filled with fire sand, which can be directly poured onto the new energy vehicle on fire through the built-in through hole. Fire sand has good flame retardant properties and can quickly cover the fire source, suppress the fire, and reduce the damage to the vehicle and surrounding facilities. This passive fire extinguishing method is particularly suitable for the spontaneous combustion of electric vehicle batteries, because battery fires usually produce high temperatures and toxic gases, and fire sand can effectively isolate oxygen and prevent the fire from further expanding.

[0014] As an auxiliary system of the fire extinguishing device, the water inlet pipe connects the support column and the fire extinguishing mechanism. Its function is to introduce water flow into the fire extinguishing mechanism to further enhance the fire extinguishing effect. Water flow can enter the fire extinguishing mechanism through the water inlet pipe and work together with the fire sand to quickly reduce the temperature of the fire source. This multi-level fire extinguishing design can take different measures according to different fire intensities and flexibly respond to various fire scenarios.

[0015] The switch assembly is installed under the fire extinguishing mechanism to control the release of the fire sand. The switch assembly can be rotated to a certain angle by the water flow, thereby opening the release channel and pouring the fire sand to the fire source. This automated process reduces the complexity of manual operation, ensuring that the fire extinguishing procedure can be started immediately when a fire occurs, reducing the losses caused by the fire.

[0016] After the isolation mechanism is released, the gravity ball in the rotating assembly will naturally fall down and drive the curtain body to unfold. This design ensures that the curtain can quickly cover the entire parking space, confining the fire within the parking space and preventing the fire from spreading to other vehicles or facilities. This isolation method not only effectively controls the scope of the fire, but also buys valuable time for firefighters to rescue.

[0017] The isolation mechanism is a key part of the automatic fire curtain device. Its structure includes a fixed block, a control chamber, an electromagnetic block, a support spring and a control block. First, the fixed block is installed on the inner side of the support column. There are four fixed blocks in total. A hollow groove is designed under each fixed block, which provides a basis for the overall stability of the device and the accommodation of other components. The design of the hollow groove helps to reduce weight while ensuring structural strength.

[0018] The control chamber is located at both ends of the fixed block. Its main function is to accommodate and control the gravity ball. Under normal circumstances, the control chamber can keep the gravity ball stable and prevent it from moving unnecessarily. The gravity ball is designed to be part of the trigger mechanism in an emergency to control the deployment of the curtain when a fire occurs, so the existence of the control chamber is crucial.

[0019] The electromagnetic block is a key component inside the control chamber and is installed in the center of the control chamber. When a fire occurs, the system will issue a command, and the electromagnetic block will be energized after receiving the signal, generating magnetism, further triggering subsequent fire prevention operations. After the electromagnetic block is energized, the gravity ball is released, causing the protective curtain to unfold and isolate the fire source, playing an effective protective role.

[0020] In addition, the support spring is located inside the control cavity to provide support for the control block. One end of the support spring is fixed inside the control cavity, and the other end is connected to the control block to ensure that the spring can support the gravity ball and keep it from falling under normal circumstances.

[0021] The control block is designed with a mirrored installation method, located inside the control chamber and connected to the support spring. Its function is to stabilize the gravity ball in the absence of a fire and prevent it from falling and triggering the curtain to unfold. This design ensures the safety of the system in non-emergency situations while ensuring a quick response in the event of a fire.

[0022] The electromagnetic block is controlled by the alarm device and will be energized to generate magnetism when a fire or a car catches fire. The bottom of the control block has magnetic material arranged opposite to the magnetic pole of the electromagnetic block, so that when a fire occurs, the electromagnetic block attracts the control block, compresses the support spring and releases the gravity ball.

[0023] The fire extinguishing mechanism is well designed and fully functional, including multiple components such as the mounting block, partition plate, through hole, water inlet channel and rotation hole. First of all, the mounting block adopts a double-layer structure, which not only improves stability but also simplifies the installation process. The lower part of the mounting block snaps into the inside of the isolation mechanism, making installation easier and facilitating future maintenance and the addition of fire sand to ensure that the system can work properly in the event of a fire.

[0024] The partition plate is installed inside the mounting block to separate different functional areas and increase the internal structural stability. Through holes are set on the upper part of the partition plate. The function of these holes is to allow fire sand to pass smoothly. When a fire occurs, the fire sand is poured into the burning area through these holes to effectively suppress the fire.

[0025] The water inlet channels are set at the four corners of the mounting block and connected to the water inlet pipe to ensure that water can quickly enter the fire extinguishing mechanism when a fire occurs to assist the fire sand fire extinguishing. The water inlet design enhances the fire extinguishing effect and adapts to a variety of fire types.

[0026] The swivel hole is located at the bottom of the mounting block and is used to install the swivel assembly. The function of the swivel assembly is to start the fire extinguishing process when a fire occurs, ensuring that the fire sand and water flow can be accurately poured into the fire area to quickly extinguish the fire.

[0027] The design of the partition is a key part of the fire extinguishing mechanism. A certain amount of fire sand is stored on it, which plays an important role in the event of a fire in a new energy vehicle. When a fire occurs, the fire sand is quickly poured to the source of the fire through the holes set on the partition, covering the burning part. The fire sand can effectively reduce the air exchange in the fire area, thereby cutting off the oxygen supply to the flames and slowing the spread of the fire. This is particularly effective for controlling electric vehicle battery fires, because battery fires are often accompanied by violent chemical reactions and high temperatures, and the fire sand can quickly cover and suppress these reactions.

[0028] The holes on the partitions are arranged in a rectangular array, so that the fire sand can be evenly distributed and quickly cover the fire source. The aperture size is designed to be 5 to 10 cm in diameter. This aperture value not only ensures that the fire sand can be quickly poured in large quantities in a short time, but also avoids the problem of blockage caused by too small apertures. The larger aperture design not only improves the efficiency of fire extinguishing, but also ensures that the fire sand covers the fire area in the shortest time, maximally controlling the fire and preventing the fire from spreading.

[0029] The design of the fire extinguishing mechanism also includes a connecting port, a sprinkler flow channel and a sprinkler port. The synergistic effect of these components further enhances the effectiveness of the fire extinguishing device. First, the connecting port is set in the middle of the water inlet channel, which is responsible for connecting the water inlet flow channel and the sprinkler flow channel. This design ensures that the water flow can flow smoothly during the fire extinguishing process, providing a reliable water supply for quickly extinguishing the fire source. The water flow must first enter the water inlet channel through the water inlet pipe, and then by pushing the internal power impeller, the water flow is driven through the connecting port into the sprinkler flow channel, and finally is evenly sprinkled through the sprinkler port to extinguish the fire and cool down the high-temperature area.

[0030] The sprinkler channel is designed in a circular layout, which helps to evenly distribute the water flow, ensuring that water can effectively cover the fire source from all angles when a fire occurs. The circular structure of the sprinkler channel not only improves the coverage of fire extinguishing, but also enhances the reliability of the entire fire extinguishing system. Even if the water flow in a certain area is blocked, other parts can still continue to sprinkle water to extinguish the fire.

[0031] The sprinkler ports are regularly opened at a certain distance below the sprinkler flow channel. This spacing design ensures the uniformity of the water flow and prevents fires from getting out of control due to uneven watering in certain areas. The water flows evenly through the sprinkler ports, which can not only quickly extinguish the flames, but also reduce the temperature of the fire source area to prevent the fire from reigniting.

[0032] The design of the switch assembly is an integral part of the fire extinguishing mechanism, which is mainly composed of a rotating shaft, a switch plate and a power impeller. These components work in precise coordination to enable the fire extinguishing system to respond quickly and initiate the fire extinguishing process when a fire occurs.

[0033] The rotating shaft is the core of the entire switch assembly. It is installed inside the fire extinguishing mechanism and is responsible for driving the operation of other components. The rotating shaft is designed with thick ends and thin middle structure. This special design helps to improve the stability and efficiency of rotation. The thick parts at both ends provide stronger support and torque, while the thin part in the middle reduces friction resistance, making the rotation smoother and more sensitive.

[0034] The switch plate is installed in the middle of the rotating shaft. When the system is not triggered, the switch plate is in a horizontal state, which plays the role of sealing the fire sand and preventing it from being released prematurely. The structural design of the switch plate ensures that it can tilt quickly when driven by the rotating shaft, releasing the fire sand to cover the fire source, thereby achieving the effect of extinguishing the fire.

[0035] The power impeller is installed at both ends of the rotating shaft and plays a key driving role. The power impeller is located in the water flow channel. When a fire occurs, the water flows into the fire extinguishing system through the water inlet pipe, driving the power impeller to rotate. The impeller starts to rotate at high speed under the action of the water flow, and then drives the rotating shaft to rotate. This power transmission mechanism ensures the coordinated operation of the rotating shaft and the switch plate. When the rotating shaft rotates, the switch plate tilts from the horizontal state, opening the channel to release the fire sand.

[0036] Through this design, the water flow not only cools down during the fire extinguishing process, but also becomes the key power source to drive the switch assembly to start. As the switch plate tilts, the fire sand is quickly poured onto the fire source through the holes in the partition plate, which plays a role in isolating oxygen and suppressing flames. The entire process is driven by water flow and does not require external energy, ensuring the efficiency and reliability of the system, especially in emergency situations, the fire extinguishing mechanism can be quickly activated.

[0037] The power impeller is set to be spherical, and the radius value of the sphere and the radius value of the water inlet channel are set to be consistent, so as to ensure the rotation efficiency of the power impeller, so that the switch component can release the fire sand faster.

[0038] The rotating assembly is a key component of the automatic fire curtain device, responsible for quickly unfolding the curtain and isolating the fire source when a fire occurs. The assembly consists of several parts, including the rotating shaft, the curtain body, the buffer block and the gravity ball. The design and cooperation of each component ensures the efficient operation of the system.

[0039] First, the rotating shaft is the core component of the rotating assembly, which is installed in the hollow groove of the fixed block. Its main function is to provide a stable rotating fulcrum so that the curtain body can be quickly unfolded in an emergency. When the system is triggered, the rotating shaft starts to rotate, driving the curtain to be quickly released to form a protective isolation layer.

[0040] The curtain body is located outside the rotating shaft and is made of silicone rubber coated glass fiber cloth. This material combination has excellent high temperature resistance and flame retardant effect, ensuring that it can still maintain strength and play an isolation role in high temperature environments of fire. The softness of silicone rubber combined with the toughness of glass fiber enables the curtain to flexibly cover the parking space when unfolded, while also having strong wear resistance and tear resistance, extending the service life of the curtain.

[0041] In order to ensure smooth and accurate unfolding of the curtain, the rotating assembly is also designed with a buffer block. The buffer block is installed at the outermost end of the curtain body and has a trapezoidal cross-section. The purpose of the design is to increase the stability of the curtain edge. When the curtain is unfolded quickly, the trapezoidal buffer block can effectively disperse the impact force during the unfolding process, preventing the curtain from excessive vibration or damage due to too fast unfolding.

[0042] The gravity ball is installed at both ends of the buffer block. It is made of high-density material and its outer layer is wrapped with a rubber layer. The main function of the gravity ball is to provide additional inertia force during the curtain deployment process to ensure that the curtain can smoothly and quickly cover the fire area. The design of the rubber layer enhances the durability of the gravity ball and avoids hard impact on surrounding objects when the curtain is deployed.

[0043] The beneficial effects of the present invention are as follows:

[0044] 1. The core of the present invention is to quickly start fire extinguishing protection measures within the first time of fire by setting up an isolation mechanism and a rotating assembly. When the fire alarm is triggered, the electromagnetic block immediately receives the signal and quickly energizes, generates magnetism, and then opens the control block. This reaction time is extremely short, ensuring that the system can respond quickly in the initial fire stage. As the control block is opened, the gravity ball will fall freely after losing support. This mechanism is crucial because the fall of the gravity ball will directly lead to the formation of an isolation zone. The design and position arrangement of the gravity ball ensure that its falling process can trigger the unfolding of the curtain, forming an effective physical barrier to quickly isolate the fire source. The formation of this isolation zone can immediately limit the spread of the fire, thereby effectively preventing the flame from spreading to other cars in the adjacent parking spaces, reducing the risk of fire spreading. Through such a design, the present invention not only improves the reaction speed of fire extinguishing, but also enhances the ability to control fire. In an emergency, the linkage of the isolation mechanism and the rotating assembly can greatly reduce the harm of the fire to the surrounding environment, providing a safer guarantee for car owners and parking lots. This highly efficient fire protection design ensures that sudden fires can be responded to quickly at critical moments, protecting people's lives and property to the greatest extent.

[0045] 2. The present invention effectively responds to the fire risk of lithium batteries used in large quantities in new energy vehicles after catching fire through the designed fire extinguishing mechanism and switch mechanism. In view of the special properties of lithium batteries, when a fire occurs, its high temperature and chemical reaction easily cause the fire to spread rapidly, thereby endangering the safety of surrounding vehicles and personnel. Therefore, the present invention adopts a series of emergency measures to ensure that the fire can be quickly and effectively controlled in the early stage of the fire. At the first moment of the fire, the fire extinguishing mechanism first quickly dumps the fire sand through a preset mechanism, and this process can quickly cover the lithium battery on fire. The main function of the fire sand is to isolate the air, cut off the supply of flames and oxygen, and inhibit the spread of the flame. This preliminary protective measure can not only slow down the fire, but also effectively reduce the release of harmful gases caused by battery combustion, and ensure the safety of surrounding personnel. Next, the switch mechanism sprays water to cool the fire area continuously by precisely controlling the water flow. The addition of water flow can quickly reduce the temperature of the battery and the surrounding environment, further preventing the spread of the fire. Water spraying for cooling can not only effectively reduce the temperature of lithium batteries and prevent the risk of secondary explosion caused by overheating, but also cool the surrounding combustible materials and reduce the possibility of causing fire again.

[0046] 3. The present invention combines the fire extinguishing mechanism and the isolation mechanism to isolate first and then extinguish the fire continuously, thus realizing the rapid response and handling capability for new energy vehicle fires. The linkage mechanism of fire sand and water spray not only improves the efficiency of fire extinguishing, but also provides a solid safety guarantee for protecting new energy vehicles and the surrounding environment. This innovative fire protection design fully considers the characteristics of new energy vehicles and provides an effective solution to the safety hazards in daily use.

[0058] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] like Figure 1-8 As shown in the figure, the automatic fire curtain device for new energy parking spaces is designed to effectively improve the safety of new energy vehicles in parking spaces. With the popularity of new energy vehicles, the risk of spontaneous combustion of electric vehicles due to battery problems has attracted widespread attention. Therefore, how to take quick measures to prevent the spread of fire when a fire occurs has become an important research topic.

[0060] The application parking space 7 is designed as a standard parking space to meet common parking needs. Support columns 6 are set at the four corners of the parking space to support the entire fire protection device. In the application scenario of the underground garage, the support column 6 can use the existing load-bearing beams, which not only saves installation costs, but also reduces the occupation of underground space. In the ground parking lot, the additional steel structure support column 6 can provide the necessary stability and support. In addition, the existing charging pile can also be transformed into a part of the support column 6, so that the fire protection device and the charging facility can be integrated into the design to improve the efficiency of space utilization.

[0061] In addition to the basic supporting structure, the automatic fire curtain device also includes multiple functional components, namely, an isolation mechanism 1, a fire extinguishing mechanism 2, a water inlet pipe 3, a switch component 4 and a rotating component 5. The coordinated work of these components can quickly respond to a fire and effectively contain the fire.

[0062] First, the isolation mechanism 1 is an important component of the device and is fixedly installed between the support columns 6. The isolation mechanism 1 is in the shape of a long strip, and four isolation mechanisms 1 together form a rectangular frame that surrounds the parking space. When a fire occurs, the electromagnetic block 13 in the isolation mechanism 1 is energized, and the control block 15 automatically opens, so that the internal rotating assembly 5 is released. After losing the control of the isolation mechanism 1, the gravity ball 54 in the rotating assembly 5 will fall naturally, driving the curtain to unfold quickly, isolating the parking space from the external environment. This design can effectively prevent flames and toxic smoke from spreading to surrounding vehicles or buildings, buy time for fire fighting, and protect the surrounding environment.

[0063] Secondly, the fire extinguishing mechanism 2 is the core fire extinguishing equipment of the entire device, which is installed in the middle part of the isolation mechanism 1. The interior of the fire extinguishing mechanism 2 is filled with fire sand, which can be directly poured onto the new energy vehicle on fire through the built-in through hole 23. Fire sand has good flame retardant properties, can quickly cover the source of fire, suppress the fire, and reduce the damage caused by the fire to the vehicle and surrounding facilities. This passive fire extinguishing method is particularly suitable for the situation of spontaneous combustion of electric vehicle batteries, because battery fires usually produce high temperatures and toxic gases, and fire sand can effectively isolate oxygen and prevent the fire from further expanding.

[0064] The water inlet pipe 3, as an auxiliary system of the fire extinguishing device, connects the support column 6 and the fire extinguishing mechanism 2. Its function is to introduce water flow into the fire extinguishing mechanism 2 to further enhance the fire extinguishing effect. The water flow can enter the fire extinguishing mechanism 2 through the water inlet pipe 3 and work together with the fire sand to quickly reduce the temperature of the fire source. Such a multi-level fire extinguishing design can take different measures according to different fire intensities and flexibly respond to various fire scenarios.

[0065] The switch assembly 4 is installed under the fire extinguishing mechanism 2 to control the release of the fire sand. The switch assembly 4 can be rotated to a certain angle by the water flow, thereby opening the release channel and pouring the fire sand to the fire source. This automated process reduces the complexity of manual operation, ensures that the fire extinguishing procedure can be started immediately when a fire occurs, and reduces the losses caused by the fire.

[0066] After the isolation mechanism 1 is released from control, the gravity ball 54 in the rotating assembly 5 will naturally fall down and drive the curtain body 52 to unfold. This design ensures that the curtain can quickly cover the entire parking space, confining the fire within the parking space and preventing the fire from spreading to other vehicles or facilities. This isolation method not only effectively controls the scope of the fire, but also buys valuable time for firefighters to rescue.

[0067] like Figure 4As shown, the isolation mechanism 1 is a key part of the automatic fire curtain device, and its structure includes a fixed block 11, a control chamber 12, an electromagnetic block 13, a support spring 14 and a control block 15. First, the fixed block 11 is installed on the inner side of the support column 6. There are four fixed blocks 11 in total. A hollow groove is designed under each fixed block 11, which provides a basis for the overall stability of the device and the accommodation of other components. The design of the hollow groove helps to reduce weight while ensuring structural strength.

[0068] The control chamber 12 is located at both ends of the fixed block 11, and its main function is to accommodate and control the gravity ball 54. Under normal circumstances, the control chamber 12 can keep the gravity ball 54 stable and prevent it from moving unnecessarily. The gravity ball 54 is designed to be part of the trigger mechanism in an emergency to control the deployment of the curtain when a fire occurs, so the existence of the control chamber 12 is crucial.

[0069] The electromagnetic block 13 is a key component inside the control chamber 12 and is installed at the center of the control chamber 12. When a fire occurs, the system will issue a command, and the electromagnetic block 13 will be energized after receiving the signal, generating magnetism, and further triggering subsequent fire prevention operations. After the electromagnetic block 13 is energized, the gravity ball 54 is released, so that the protective curtain is unfolded to isolate the fire source, playing an effective protective role.

[0070] In addition, the support spring 14 is located inside the control chamber 12 to provide support for the control block 15. One end of the support spring 14 is fixed inside the control chamber 12, and the other end is connected to the control block 15, ensuring that the spring can support the gravity ball 54 under normal circumstances and keep it from falling.

[0071] The control block 15 is designed in a mirror-image installation manner, located inside the control chamber 12 and connected to the support spring 14. Its function is to stabilize the gravity ball 54 in the absence of a fire, preventing it from falling and triggering the curtain to unfold. This design ensures the safety of the system in non-emergency situations, while ensuring a quick response in the event of a fire.

[0072] The electromagnetic block 13 is controlled by the alarm device and will be energized to generate magnetism when a fire or a car spontaneously combusts. The bottom of the control block 15 has a magnetic material arranged with a magnetic pole opposite to that of the electromagnetic block 13, so that when a fire occurs, the electromagnetic block 13 attracts the control block 15, compresses the support spring 14, and then releases the gravity ball 54.

[0073] like Figure 5-6As shown, the fire extinguishing mechanism 2 is exquisitely designed and fully functional, including a plurality of components such as a mounting block 21, a partition plate 22, a through hole 23, a water inlet channel 24 and a rotating hole 25. First, the mounting block 21 adopts a double-layer structure, which not only improves stability but also simplifies the installation process. The lower part of the mounting block 21 is snap-fitted with the interior of the isolation mechanism 1, making the installation easier and facilitating future maintenance and the addition of fire sand, ensuring that the system can work normally in the event of a fire.

[0074] The partition plate 22 is installed inside the mounting block 21 to separate different functional areas and increase the internal structural stability. Through holes 23 are provided on the upper part of the partition plate 22 to allow fire sand to pass smoothly. When a fire occurs, the fire sand is poured into the burning area through these holes to effectively suppress the fire.

[0075] The water inlet channel 24 is arranged at the four corners of the mounting block 21 and is connected to the water inlet pipe 3 to ensure that water can quickly enter the fire extinguishing mechanism 2 when a fire occurs to assist the firefighting sand in extinguishing the fire. The water inlet design enhances the fire extinguishing effect and is suitable for various types of fires.

[0076] The rotating hole 25 is located at the lower part of the mounting block 21 and is used to install the rotating assembly 5. The function of the rotating assembly 5 is to start the fire extinguishing process when a fire occurs, to ensure that the fire sand and water flow can be accurately poured into the fire area and quickly extinguish the fire source.

[0077] The design of the partition plate 22 is a key part of the fire extinguishing mechanism 2. A certain amount of fire sand is stored on it, which plays an important role when a fire occurs in a new energy vehicle. When a fire occurs, the fire sand is quickly poured to the fire source through the holes set on the partition plate 22 to cover the burning part. The fire sand can effectively reduce the air exchange in the fire area, thereby cutting off the oxygen supply to the flame and slowing down the spread of the fire. This is particularly effective for controlling electric vehicle battery fires, because battery fires are often accompanied by violent chemical reactions and high temperatures, and the fire sand can quickly cover and suppress these reactions.

[0078] The through holes 23 on the partition plate 22 are arranged in a rectangular array so that the firefighting sand can be evenly distributed and quickly cover the fire source. The aperture size is designed to be 5 to 10 cm in diameter. Such an aperture value not only ensures that the firefighting sand can be quickly poured in large quantities in a short time, but also avoids the problem of blockage caused by too small an aperture. The larger aperture design not only improves the efficiency of fire extinguishing, but also ensures that the firefighting sand covers the fire area in the shortest time, controls the fire to the maximum extent, and prevents the fire from spreading.

[0079] The design of the fire extinguishing mechanism 2 also includes a connecting port 26, a water sprinkling channel 27 and a water sprinkling port 28. The synergistic effect of these components further enhances the effect of the fire extinguishing device. First, the connecting port 26 is set in the middle of the water inlet channel 24, responsible for connecting the water inlet channel and the water sprinkling channel 27. This design ensures that the water flow can flow smoothly during the fire extinguishing process, providing a reliable water supply for quickly extinguishing the fire source. The water flow must first enter the water inlet channel 24 through the water inlet pipe 3, and then by pushing the internal power impeller 43, the water flow is driven through the connecting port 26 into the water sprinkling channel 27, and finally is evenly sprinkled through the water sprinkling port 28 to extinguish the fire and cool down the high temperature area.

[0080] The sprinkler flow channel 27 is designed in a ring layout, which helps to evenly distribute the water flow, ensuring that water can effectively cover the fire source from all angles when a fire occurs. The ring structure of the sprinkler flow channel 27 not only improves the coverage of fire extinguishing, but also enhances the reliability of the entire fire extinguishing system. Even if the water flow in a certain area is blocked, other parts can still continue to sprinkle water to extinguish the fire.

[0081] The sprinkler ports 28 are regularly arranged at a certain distance below the sprinkler flow channel 27. Such a spacing design ensures the uniformity of the water flow and prevents fires from getting out of control due to uneven watering in certain areas. The water flow is evenly sprinkled through the sprinkler ports 28, which can not only quickly extinguish the flames, but also reduce the temperature of the fire source area to prevent the fire from reigniting.

[0082] like Figure 7 As shown, the design of the switch assembly 4 is an indispensable part of the fire extinguishing mechanism 2, which is mainly composed of a rotating shaft 41, a switch plate 42 and a power impeller 43. These components work in precise coordination so that the fire extinguishing system can respond quickly and start the fire extinguishing process when a fire occurs.

[0083] The rotating shaft 41 is the core of the entire switch assembly 4. It is installed inside the fire extinguishing mechanism 2 and is responsible for driving the operation of other components. The design of the rotating shaft 41 adopts a structure with thick ends and thin middle. This special design helps to improve the stability and efficiency of rotation. The thick parts at both ends provide stronger support and torque, while the thin part in the middle reduces friction resistance, making the rotation smoother and more sensitive.

[0084] The switch plate 42 is installed in the middle of the rotating shaft 41. When the system is not triggered, the switch plate 42 is in a horizontal state, which plays a role in sealing the fire sand and preventing it from being released in advance. The structural design of the switch plate 42 ensures that it can be quickly tilted when driven by the rotating shaft 41, releasing the fire sand to cover the fire source, thereby achieving the effect of extinguishing the fire.

[0085] The power impeller 43 is installed at both ends of the rotating shaft 41 and plays a key driving role. The power impeller 43 is located in the channel of the water flow. When a fire occurs, the water flows into the fire extinguishing system through the water inlet pipe 3, driving the power impeller 43 to rotate. The impeller starts to rotate at a high speed under the action of the water flow, and then drives the rotating shaft 41 to rotate. This power transmission mechanism ensures the coordinated operation of the rotating shaft 41 and the switch plate 42. When the rotating shaft 41 rotates, the switch plate 42 tilts from the horizontal state, opening the channel to release the fire sand.

[0086] Through this design, the water flow not only cools down during the fire extinguishing process, but also becomes the key power source for driving the switch assembly 4 to start. As the switch plate 42 tilts, the fire sand is quickly poured onto the fire source through the holes of the partition plate 22, which plays a role in isolating oxygen and suppressing flames. The entire process is driven by water flow and does not require external energy, ensuring the efficiency and reliability of the system, especially in emergency situations, the fire extinguishing mechanism can be quickly started.

[0087] The power impeller 43 is set to be spherical, and the radius of the sphere is set to be consistent with the radius of the water inlet channel 24, so as to ensure the rotation efficiency of the power impeller 43, so that the switch assembly 4 can release the fire sand faster.

[0088] like Figure 8 As shown, the rotating assembly 5 is a key component of the automatic fireproof curtain device, which is responsible for quickly unfolding the curtain and isolating the fire source when a fire occurs. The assembly consists of a rotating shaft 51, a curtain body 52, a buffer block 53 and a gravity ball 54. The design and cooperation of each component ensures the efficient operation of the system.

[0089] The rotating shaft 51 is the core component of the rotating assembly 5 and is installed in the hollow groove of the fixed block 11. Its main function is to provide a stable rotating fulcrum so that the curtain body 52 can be quickly deployed in an emergency. When the system is triggered, the rotating shaft 51 starts to rotate, driving the curtain to be quickly released to form a protective isolation layer.

[0090] The curtain body 52 is located outside the rotating shaft 51, and its material is silicone rubber coated glass fiber cloth. This material combination has excellent high temperature resistance and flame retardant effect, ensuring that it can still maintain strength and play an isolation role in a high temperature environment of a fire. The softness of silicone rubber combined with the toughness of glass fiber enables the curtain to flexibly cover the parking space when unfolded, and at the same time has strong wear resistance and tear resistance, extending the service life of the curtain.

[0091] In order to ensure smooth and accurate unfolding of the curtain, the rotating assembly 5 is also designed with a buffer block 53. The buffer block 53 is installed at the outermost end of the curtain body 52 and has a trapezoidal cross section. The purpose of the design is to increase the stability of the edge of the curtain. When the curtain is unfolded quickly, the trapezoidal buffer block 53 can effectively disperse the impact force during the unfolding process, preventing the curtain from excessive vibration or damage due to too fast unfolding.

[0092] The gravity ball 54 is installed at both ends of the buffer block 53 and is made of high-density material with a rubber layer wrapped around its outer layer. The main function of the gravity ball 54 is to provide additional inertial force during the unfolding of the curtain to ensure that the curtain can smoothly and quickly cover the fire area. The design of the rubber layer enhances the durability of the gravity ball 54 and avoids hard impact on surrounding objects when the curtain is unfolded.

[0093] During the working process of the present invention, the new energy vehicle is parked in the application parking space 7. Once a spontaneous combustion occurs,

[0094] The smoke alarm and the fire alarm immediately sound an alarm, and the alarm device controls the electromagnetic block 13 to be energized to generate magnetism, so that the battery block attracts the control block 15 to overcome the elastic force of the support spring 14 and shrink, and the gravity ball 54 can fall freely;

[0095] During the rapid fall of the gravity ball 54, the curtain body 52 is driven to fall, and the rebound is reduced by the buffering effect of the buffer block 53, and the accuracy of the falling position is ensured. Thus, the four rotating components 5 operate simultaneously to isolate the parking space 7, which reduces air circulation on the one hand and prevents the fire from spreading further on the other hand.

[0096] The water inlet pipe 3 quickly transports water or liquid fire extinguishing agent under the action of the water pump. The water enters the water inlet channel 24 through the water inlet pipe 3 and drives the power impeller 43 to rotate. Then, the water enters the annular water sprinkling channel 27 through the connecting port 26 and is finally sprayed from the water sprinkling port 28 onto the new energy vehicle on fire to cool down and extinguish the fire.

[0097] The rotation of the power impeller 43 causes the switch plate 42 to tilt, thereby preventing the fire sand inside the mounting plate from being dumped onto the new energy vehicle through the through hole 23. In this process, the setting of the partition plate 22 plays a role in evenly dumping the fire sand to obtain a better fire extinguishing effect. If the partition plate 22 is not provided, since the water flow line has a fixed route, the fire sand will be dumped preferentially from a place close to the water inlet channel 24, resulting in a poor fire extinguishing effect.

Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope consistent with the principles and novel features disclosed herein.
