Description

Automatic fireproof curtain device for new energy parking space TECHNICAL FIELD

[0001] The present application relates to the technical field of parking fireproof curtain, in particular to an automatic fireproof curtain device for new energy parking space. BACKGROUND

[0002] New energy vehicles (electric vehicles) have attracted widespread attention due to their fire and spontaneous combustion problems, especially as they become more popular in the market. New energy vehicles mostly use lithium-ion batteries. The energy density of such batteries is high, but if the battery is internally short-circuited, overcharged, over-discharged, or suffers physical damage, it may lead to a "thermal runaway" phenomenon, with the battery temperature rising sharply, eventually causing a fire. The battery management system (BMS) is responsible for monitoring and controlling the charging and discharging state of the battery. If the BMS fails, it may not be able to detect abnormal conditions of the battery in time, leading to overheating or short-circuiting of the battery, and further causing spontaneous combustion. In the event of a traffic accident or when a vehicle is hit by an external force, the battery pack may be damaged. 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 environmental temperatures (such as high temperatures) increase the risk of battery spontaneous combustion.

[0003] The role of the fireproof curtain on the parking space is to provide a fire barrier, mainly used to delay the spread of fire, block the spread of flames and toxic smoke in the event of a fire. Especially in the case of new energy vehicles (such as electric vehicles) causing fires due to battery thermal runaway, etc., the fireproof curtain can help protect surrounding vehicles and buildings. When a vehicle spontaneously combusts or catches fire, the fireproof curtain can quickly deploy to form a barrier, preventing the spread of flames to surrounding vehicles. This is particularly important for underground parking lots or densely packed parking lots, as the space between vehicles is usually small, and fires can easily spread from one vehicle to others. The fireproof curtain can help suppress the high temperature of the fire, avoiding direct contact of the flames with surrounding vehicles or structures, thereby reducing the heat radiation damage caused by the fire and protecting the surfaces of adjacent vehicles and buildings. When a fire occurs, especially when an electric vehicle battery catches fire, it may produce a large amount of toxic gas. The fireproof curtain can effectively block and delay the spread of these toxic fumes, providing valuable time for personnel evacuation and fire rescue personnel to rescue, reducing the harm of smoke to the human body.

[0004] The fireproof curtain plays a key role in protecting surrounding vehicles and buildings, slowing down the spread of fire, reducing smoke diffusion, and providing rescue time on the parking space. It is an effective fire safety measure, especially suitable for enclosed spaces such as underground garages or large parking lots, helping to reduce the damage caused by fire risk.

[0005] In the process of spontaneous combustion of new energy vehicles, the chemical reaction in the battery may accelerate, thereby increasing the risk of fire. Unqualified charging equipment or improper charging operation, especially long-time overcharging, may cause the battery temperature to be too high, thereby increasing the risk of fire in the underground garage or other scenarios of new energy vehicle parking spaces.

[0006] In view of the above, in order to overcome the above technical problems, the present application designs an automatic fireproof curtain device for new energy parking space, which solves the above technical problems.

[0007] SUMMARY

[0008] The technical purpose to be achieved by the present application is to design an automatic fireproof curtain device for new energy parking space, which can quickly form an isolation zone and cover it with fire-fighting sand and continuous water spraying cooling treatment when a new energy vehicle catches fire due to charging or high outdoor temperature, thereby minimizing the loss.

[0009] In order to achieve the above technical purpose, the present application provides the following technical scheme:

[0010] The automatic fireproof curtain device for new energy parking space aims to effectively improve the safety of new energy vehicles in parking spaces. With the popularity of new energy vehicles, the risk of electric vehicles catching fire due to battery problems has attracted widespread attention, therefore, how to quickly take measures when a fire occurs to prevent the spread of fire has become an important research topic.

[0011] The parking space is designed as a standard parking space to meet the common parking needs. The support columns are arranged at the four corners of the parking space to support the entire fireproof device. In the application scenario of underground garage, the support columns can utilize the existing load-bearing beams, which not only saves the installation cost, but also reduces the occupation of underground space. In the above-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 modified to become part of the support column, so that the fireproof device and the charging facility are integrated and designed to improve the space utilization efficiency.

[0012] In addition to the basic support structure, the automatic fireproof curtain device also includes multiple functional components, which are isolation mechanism, fire extinguishing mechanism, water inlet pipe, switch assembly and rotating component. The coordinated work of these components can quickly respond when a fire occurs and effectively control the fire.

[0013] Firstly, the isolation mechanism is an important part of the device, fixedly installed between the support columns. The isolation mechanism is long strip-shaped, and four isolation mechanisms together form a rectangular frame surrounding the parking space. When a fire occurs, the electromagnetic block in the isolation mechanism is powered on, the control block is automatically opened, and the internal rotating assembly is released. The gravity ball in the rotating assembly naturally falls after losing the control of the isolation mechanism, drives the curtain to quickly unfold, and isolates the parking space from the external environment. This design can effectively prevent the spread of flames and toxic smoke to surrounding vehicles or buildings, gain time for fire extinguishing, and protect the surrounding environment.

[0014] Secondly, the fire extinguishing mechanism is the core fire extinguishing equipment of the entire device, installed in the middle part of the isolation mechanism. The fire extinguishing mechanism is filled with fire sand inside, which can be directly poured on the new energy vehicle on fire through the built-in through hole. The fire sand has good fire retardant performance, can quickly cover the fire source, suppress the fire, and reduce the damage of the fire to the vehicle and surrounding facilities. This passive fire extinguishing method is especially suitable for the case of electric vehicle battery self-ignition, because the battery fire usually produces high temperature and toxic gas, and the fire sand can effectively isolate oxygen to prevent the fire from further expanding.

[0015] The water inlet pipe, as an auxiliary system of the fire extinguishing device, connects the support column and the fire extinguishing mechanism. Its role is to introduce water flow into the fire extinguishing mechanism to further enhance the fire extinguishing effect. The water flow can enter the fire extinguishing mechanism through the water inlet pipe and act 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 cope with various fire scenes.

[0016] The switch assembly is installed below the fire extinguishing mechanism and controls the release of fire sand. The switch assembly can be rotated by a certain angle by the water flow to open the release channel and pour the fire sand to the fire source. This automatic process reduces the complexity of human operation, ensures that the fire extinguishing program can be started at the first time when a fire occurs, and reduces the loss caused by the fire.

[0017] The gravity ball in the rotating assembly naturally falls after the control of the isolation mechanism is released, and drives the curtain body to unfold. This design ensures that the curtain can quickly cover the entire parking space and limit the fire within the parking space, avoiding the spread of the fire to other vehicles or facilities. This isolation method not only effectively controls the range of the fire, but also gains valuable time for the rescue of the fire personnel.

[0018] The isolation mechanism is a key part of the automatic fireproof curtain device, its structure includes fixed block, control cavity, electromagnetic block, support spring and control block. First, the fixed block is installed on the inside of the support column, a total of four fixed blocks, each fixed block is designed with a hollow groove below, which provides a foundation for the overall stability of the device and the accommodation of other components. The design of the hollow groove helps to reduce the weight while ensuring the structural strength.

[0019] The control cavity 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 cavity can keep the gravity ball stable and prevent unnecessary movement. The design of the gravity ball is part of the trigger mechanism in emergency situations to control the deployment of the curtain when a fire occurs, so the existence of the control cavity is crucial.

[0020] The electromagnetic block is a key element inside the control cavity, installed at the center of the control cavity. When a fire occurs, the system will issue an instruction, and the electromagnetic block will be powered on after receiving the signal, generating magnetism and further triggering subsequent fire protection operations. The electromagnetic block is powered on to release the gravity ball, allowing the protective curtain to deploy to isolate the fire source and effectively protect.

[0021] In addition, the support spring is located inside the control cavity, which provides support force 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, ensuring that the spring can support the gravity ball and keep it from falling under normal circumstances.

[0022] The control block is designed with a mirror image installation method, located inside the control cavity and connected to the support spring. Its role is to stabilize the gravity ball in the absence of fire and prevent it from falling to trigger the curtain deployment. This design ensures the safety of the system in non-emergency situations while ensuring rapid response in the event of a fire.

[0023] The electromagnetic block is controlled by the alarm device and will be powered on to generate magnetism when a fire or car fire occurs. The bottom of the control block has a magnetic material opposite the magnetic pole of the electromagnetic block, which allows the electromagnetic block to attract the control block and compress the support spring to release the gravity ball when a fire occurs.

[0024] The fire extinguishing mechanism is designed with a variety of components, including mounting block, partition plate, through hole, water inlet channel and rotating hole. First, 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 is connected to the inside of the isolation mechanism, making installation more convenient for future maintenance and fire sand addition, ensuring that the system can work normally in the event of a fire.

[0025] The partition plate is installed inside the mounting block to separate different functional areas, increasing the internal structural stability. The partition plate has through holes in the upper part, which allow the fire sand to pass through smoothly. When a fire occurs, the fire sand is poured into the burning area through these holes, effectively suppressing the fire.

[0026] The water inlet channel is located at the four corners of the mounting block and is connected to the water inlet pipe to ensure that the water flow can quickly enter the fire extinguishing mechanism to assist the fire sand in extinguishing the fire. The water inlet design enhances the fire extinguishing effect and adapts to various types of fires.

[0027] The rotating hole is located at the lower part of the mounting block and is used to install the rotating assembly. The rotating assembly is used 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 source.

[0028] The partition plate design is a key part of the fire extinguishing mechanism, which stores a certain amount of fire sand above. These fire sands play an important role in new energy vehicle fires. When a fire occurs, the fire sand is quickly poured into the fire source through the holes in the partition plate, covering the fire area. Fire sand can effectively reduce air exchange in the fire area, 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, as battery fires often involve intense chemical reactions and high temperatures, and fire sand can quickly cover and suppress these reactions.

[0029] The through holes on the partition plate are arranged in a rectangular array, allowing the fire sand to be evenly distributed and quickly cover the fire source. The hole diameter is designed to be 5 to 10 cm in diameter, which not only ensures that the fire sand can be poured quickly and in large quantities in a short time, but also avoids the problem of blockage caused by too small a hole diameter. Larger hole diameters not only improve the efficiency of fire extinguishing, but also ensure that the fire sand covers the fire area in the shortest time, maximizes the control of the fire, and prevents the spread of the fire.

[0030] The design of the fire extinguishing mechanism also includes a communication port, a water flow channel, and a water outlet. The coordinated action of these components further enhances the effectiveness of the fire extinguishing device. First, the communication port is located in the middle of the water inlet channel and is responsible for connecting the water inlet channel and the water 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, then be driven through the internal power impeller, and finally be evenly sprayed through the water outlet to extinguish the fire and cool the high-temperature area.

[0031] The design of the water flow channel is in a circular layout, which helps to distribute the water flow evenly and ensure that the water can effectively cover the fire source from all angles in the event of a fire. The circular structure of the water flow channel not only increases the coverage of the 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.

[0032] The sprinkler openings are regularly spaced at certain intervals below the water flow channel. This interval design ensures the uniformity of water flow and prevents some areas from losing control due to uneven sprinkling. The water flow is evenly sprayed through the sprinkler openings, not only quickly extinguishing the flames, but also reducing the temperature of the fire source area to prevent the fire from rekindling.

[0033] The design of the switch assembly is an integral part of the fire extinguishing mechanism, which mainly consists of a rotating shaft, a switch plate and a power impeller. These components work together precisely to enable the fire extinguishing system to respond quickly and start the fire extinguishing process when a fire occurs.

[0034] The rotating shaft is the core of the entire switch assembly, which is installed inside the fire extinguishing mechanism and is responsible for driving the operation of other components. The design of the rotating shaft adopts a structure with thick ends and a thin middle, which helps to improve the stability and efficiency of rotation. The thick ends provide stronger support and torque, while the thin middle reduces frictional resistance, making rotation smoother and more sensitive.

[0035] 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, acting as a barrier to prevent the release of fire sand in advance. The structural design of the switch plate ensures that it can tilt quickly when driven by the rotating shaft, releasing fire sand to cover the fire source and achieving the effect of extinguishing the fire.

[0036] 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, 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 water flow, 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.

[0037] Through this design, the water flow not only lowers the temperature during the extinguishing process, but also becomes the key power source to drive the switch assembly to start. With the tilting of the switch plate, the fire sand quickly pours through the holes of the partition plate onto the fire source, playing a role in isolating oxygen and suppressing flames. The entire process is driven by water flow, without the need for external energy, ensuring the efficiency and reliability of the system, especially in emergency situations, it can quickly start the fire extinguishing mechanism.

[0038] The power impeller is arranged in a spherical shape, and the radius of the power impeller and the radius of the water inlet channel are arranged to be consistent, so as to ensure the rotation efficiency of the power impeller, so that the switch assembly can release the fire-fighting sand faster.

[0039] The rotating assembly is a key component of the automatic fireproof curtain device, responsible for rapidly deploying the curtain to isolate the fire source when a fire occurs. The assembly consists of a rotating shaft, a curtain body, a buffer block, and a gravity ball. The design and cooperation of each component ensure efficient operation of the system.

[0040] Firstly, the rotating shaft is the core component of the rotating assembly, installed in the hollow groove of the fixed block. Its main function is to provide a stable rotating fulcrum, allowing the curtain body to quickly deploy in emergency situations. When the system is triggered, the rotating shaft begins to rotate, driving the curtain to release rapidly and form a protective isolation layer.

[0041] 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 maintain strength and play an isolation role in high-temperature fire environments. The softness of silicone rubber combined with the toughness of glass fiber allows the curtain to flexibly cover the surrounding area when it is deployed, while also having strong wear resistance and tear resistance, extending the service life of the curtain.

[0042] To ensure the stability and accuracy of the curtain deployment, the rotating assembly also includes a buffer block. The buffer block is installed at the outermost end of the curtain body and has a trapezoidal cross-section, designed to increase the stability of the curtain edge. When the curtain is rapidly deployed, the trapezoidal buffer block effectively disperses the impact force during deployment, preventing excessive vibration or damage to the curtain due to rapid deployment.

[0043] The gravity ball is installed at both ends of the buffer block and is made of high-density material, with a rubber layer on the outside. The main function of the gravity ball is to provide additional inertial force during curtain deployment, ensuring that the curtain can smoothly and quickly cover the fire area. The rubber layer design enhances the durability of the gravity ball and avoids hard impact on surrounding objects during curtain deployment.

[0044] The beneficial effects of the present invention are as follows:

[0045] 1. The core of this invention lies in its ability to rapidly activate fire extinguishing and protection measures in the immediate aftermath of a fire by incorporating an isolation mechanism and a rotating component. When the fire alarm is triggered, the electromagnetic block immediately receives the signal and is rapidly energized, generating magnetism and opening the control block. This extremely short reaction time ensures the system can respond quickly in the initial stages of a fire. As the control block opens, the gravity ball, having lost its support, falls freely. This mechanism is crucial because the fall of the gravity ball directly leads to the formation of an isolation zone. The design and placement of the gravity ball ensure that its descent triggers the unfolding of the curtain, forming an effective physical barrier that quickly isolates the fire source. The formation of this isolation zone immediately limits the spread of the fire, effectively preventing the flames from spreading to other cars in adjacent parking spaces and reducing the risk of fire spread. Through this design, this invention not only improves the response speed of fire extinguishing but also enhances the ability to control fires. In emergencies, the linkage between the isolation mechanism and the rotating component can significantly reduce the harm of the fire to the surrounding environment, providing greater safety for car owners and parking lots. This highly efficient fire-resistant design ensures a rapid response to sudden fires in critical moments, maximizing the protection of people's lives and property.

[0046] 2. This invention effectively addresses the fire risk posed by lithium batteries, widely used in new energy vehicles, through its designed fire extinguishing and switching mechanisms. Due to the unique properties of lithium batteries, their high temperatures and chemical reactions during a fire can easily cause the fire to spread rapidly, endangering the safety of surrounding vehicles and personnel. Therefore, this invention employs a series of emergency measures to ensure rapid and effective fire control in the initial stages. Immediately upon the onset of a fire, the fire extinguishing mechanism first rapidly pours fire-fighting sand through a pre-set mechanism, quickly covering the burning lithium battery. The fire-fighting sand primarily isolates the air, cutting off the supply of oxygen to the flames and inhibiting the spread of the fire. This initial protective measure not only slows the fire but also effectively reduces the release of harmful gases caused by battery combustion, ensuring the safety of surrounding personnel. Subsequently, the switching mechanism precisely controls the water flow, continuously spraying water to cool the fire area. The addition of water rapidly lowers the temperature of the battery and the surrounding environment, further preventing the fire from spreading. Spraying water to cool down the lithium battery can not only effectively reduce its temperature and prevent the risk of secondary explosion caused by overheating, but also cool the surrounding flammable materials and reduce the possibility of another fire.

[0047] 3.The application combines the fire extinguishing mechanism and the isolation mechanism, first isolates and then continuously extinguishes the fire, realizes the rapid response and processing capacity for new energy vehicle fire, and the linkage mechanism of fire-fighting sand and water spraying 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 fireproof design fully considers the characteristics of new energy vehicles and provides an effective solution to safety hazards in daily use. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0059] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings and specific embodiments of the specification.

[0060] As shown in FIGS. 1-8, the automatic fireproof curtain device for new energy parking space aims to effectively improve the safety of new energy vehicles in parking spaces. With the popularity of new energy vehicles, the risk of electric vehicles catching fire due to battery problems has attracted widespread attention, therefore, how to take quick measures when a fire occurs to prevent the spread of fire has become an important research topic.

[0061] The application parking space 7 is designed as a standard parking space to meet common parking needs. The support column 6 is arranged at the four corners of the parking space and supports the entire fireproof device. In the application scenario of underground garage, the support column 6 can utilize the existing load-bearing beam, which not only saves installation cost, but also reduces the occupation of underground space. While in the aboveground 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 modified to become part of the support column 6, so that the fireproof device and charging facilities are integrated and designed to improve space utilization efficiency.

[0062] In addition to the basic support structure, the automatic fireproof curtain device also includes multiple functional components, namely the isolation mechanism 1, the fire extinguishing mechanism 2, the water inlet pipe 3, the switch assembly 4 and the rotating assembly 5. The coordinated work of these components can quickly respond to fire and effectively contain the fire.

[0063] Firstly, the isolation mechanism 1 is an important part 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 the four isolation mechanisms 1 together form a rectangular frame surrounding the parking space. When a fire occurs, the electromagnetic block 13 in the isolation mechanism 1 is powered on, and the control block 15 automatically opens, so that the internal rotating assembly 5 is released. The gravity ball 54 in the rotating assembly 5 will naturally fall after losing the control of the isolation mechanism 1, driving the curtain to quickly expand and isolate the parking space from the external environment. This design can effectively prevent the spread of flames and toxic smoke to surrounding vehicles or buildings, buying time for fire extinguishing and protecting the surrounding environment.

[0064] Secondly, the fire extinguishing mechanism 2 is the core fire extinguishing equipment of the entire device and is installed in the middle part of the isolation mechanism 1. The fire extinguishing mechanism 2 is filled with fire sand, which can be directly poured on the new energy vehicle on fire through the built-in through hole 23. The fire sand has good fire retardant performance and can quickly cover the fire source, suppress the fire and reduce the damage of the fire to the vehicle and surrounding facilities. This passive fire extinguishing method is particularly suitable for the case of electric vehicle battery fire, because the battery fire usually produces high temperature and toxic gas, and the fire sand can effectively isolate oxygen and prevent the fire from further expanding.

[0065] The water inlet pipe 3, as an auxiliary system of the fire extinguishing device, is connected to the support column 6 and the fire extinguishing mechanism 2. Its function is to introduce water flow into the fire extinguishing mechanism 2, further enhancing 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. This multi-level fire extinguishing design can take different measures according to different fire intensities, and flexibly cope with various fire scenes.

[0066] The switch assembly 4 is installed below the fire extinguishing mechanism 2, which controls the release of fire sand. The switch assembly 4 can be rotated by a certain angle by the water flow, thereby opening the release channel and dumping the fire sand to the fire source. This automatic process reduces the complexity of human operation, ensures that the fire extinguishing program can be started at the first time when the fire occurs, and reduces the loss caused by the fire.

[0067] The gravity ball 54 in the rotating assembly 5 will naturally fall after the isolation mechanism 1 is released, and drive the curtain body 52 to expand. This design ensures that the curtain can quickly cover the entire parking space, limiting the fire within the parking space and preventing the spread of fire to other vehicles or facilities. This isolation method not only effectively controls the scope of the fire, but also gains valuable time for the rescue of firefighters.

[0068] As shown in Figure 4, the isolation mechanism 1 is a key part of the automatic fireproof curtain device, and its structure includes fixed blocks 11, control cavities 12, electromagnetic blocks 13, support springs 14 and control blocks 15. First, the fixed blocks 11 are installed on the inside of the support column 6, and there are a total of four fixed blocks 11, each of which is designed with a hollow groove on the bottom, 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 the weight while ensuring the structural strength.

[0069] The control cavity 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 cavity 12 can keep the gravity ball 54 stable and prevent unnecessary movement. The design of the gravity ball 54 is part of the trigger mechanism in an emergency to control the expansion of the curtain when a fire occurs, so the existence of the control cavity 12 is crucial.

[0070] The electromagnetic block 13 is a key element inside the control cavity 12, installed at the center of the control cavity 12. When a fire occurs, the system will issue an instruction, and the electromagnetic block 13 will be powered after receiving the signal, generating magnetism and further triggering subsequent fire prevention operations. The electromagnetic block 13 is powered to release the gravity ball 54, so that the protective curtain is expanded to isolate the fire source, effectively protecting the fire source.

[0071] In addition, the support spring 14 is located inside the control cavity 12, which provides support force for the control block 15. One end of the support spring 14 is fixed inside the control cavity 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.

[0072] The control block 15 is designed with a mirror image installation method, located inside the control cavity 12 and connected to the support spring 14. Its role is to stabilize the gravity ball 54 in the absence of fire and prevent it from falling to trigger the curtain deployment. This design ensures the safety of the system in non-emergency situations, while ensuring rapid response in the event of a fire.

[0073] The electromagnetic block 13 is controlled by the alarm device and will be energized when a fire or vehicle self-ignition occurs, generating a magnetic field. The bottom of the control block 15 has magnetic material arranged opposite the magnetic poles of the electromagnetic block 13, allowing the electromagnetic block 13 to attract the control block 15, compress the support spring 14, and release the gravity ball 54 when a fire occurs.

[0074] As shown in Figures 5-6, the fire extinguishing mechanism 2 is designed with precision and comprehensive functionality, including installation block 21, partition plate 22, through hole 23, water inlet channel 24, and rotating hole 25. First, the installation block 21 adopts a double-layer structure, which not only improves stability but also simplifies the installation process. The lower part of the installation block 21 is connected to the inside of the isolation mechanism 1, making installation more convenient and facilitating future maintenance and addition of fire sand, ensuring that the system can work normally in the event of a fire.

[0075] The partition plate 22 is installed inside the installation block 21 to separate different functional areas, increasing the structural stability of the interior. Through holes 23 are provided on the upper part of the partition plate 22, which allow fire sand to pass through smoothly. When a fire occurs, fire sand is poured into the burning area through these holes, effectively suppressing the fire.

[0076] The water inlet channel 24 is located in the four corners of the installation 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, assisting the fire sand in extinguishing the fire. The design of the water inlet enhances the extinguishing effect and adapts to various types of fires.

[0077] The rotating hole 25 is located in the lower part of the installation block 21 and is used to install the rotating assembly 5. The role of the rotating assembly 5 is to start the fire extinguishing process when a fire occurs, ensuring that fire sand and water flow can be accurately poured into the fire area to quickly extinguish the source of the fire.

[0078] The design of the partition plate 22 is a key part of the fire extinguishing mechanism 2, which stores a certain amount of fire sand above it. These fire sands play an important role when a new energy vehicle catches fire. When a fire occurs, the fire sand quickly pours through the holes on the partition plate 22 to the fire source, covering the part where the fire breaks out. Fire sand can effectively reduce air exchange in the fire area, thereby cutting off the oxygen supply of the flame and slowing down the spread of the fire. This is particularly effective for controlling electric vehicle battery fires, as battery fires are often accompanied by intense chemical reactions and high temperatures, and fire sand can quickly cover and suppress these reactions.

[0079] The through holes 23 on the partition plate 22 are arranged in a rectangular array, allowing the fire sand to be evenly distributed and quickly cover the fire source. The hole diameter is designed to be 5 to 10 cm in diameter, which not only ensures that the fire sand pours quickly and in large quantities in a short time, but also avoids the problem of blockage that may occur with smaller hole diameters. Larger hole diameters not only improve the efficiency of fire extinguishing, but also ensure that the fire sand covers the fire area in the shortest time, maximizes the control of the fire, and prevents the spread of the fire.

[0080] The design of the fire extinguishing mechanism 2 also includes the communication port 26, the water flow channel 27 and the water outlet 28, which work together to further enhance the effectiveness of the fire extinguishing device. First, the communication port 26 is located in the middle of the water inlet channel 24, responsible for connecting the water inlet channel and the water flow 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, then be driven through the communication port 26 into the water flow channel 27 by the internal power impeller 43, and finally be evenly sprayed out through the water outlet 28 to extinguish the fire and cool the high-temperature area.

[0081] The water flow channel 27 is designed in a ring shape, which helps to evenly distribute the water flow and ensure that the water can effectively cover the fire source from all angles when a fire occurs. The ring-shaped structure of the water flow channel 27 not only improves the coverage of the 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 spray water to extinguish the fire.

[0082] The water outlet 28 is regularly opened under the water flow channel 27 at a certain distance. This interval design ensures the uniformity of the water flow, preventing some areas from losing control due to uneven water spraying. The water flow is evenly sprayed through the water outlet 28, which not only quickly extinguishes the flame, but also lowers the temperature of the fire area to prevent the fire from reigniting.

[0083] As shown in Figure 7, the design of the switch assembly 4 is an integral 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 together precisely to enable the fire extinguishing system to respond quickly and start the fire extinguishing process when a fire occurs.

[0084] The rotating shaft 41 is the core of the entire switch assembly 4, which 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 a thin middle, which helps to improve the stability and efficiency of rotation. The thick ends provide stronger support and torque, while the thin middle reduces frictional resistance, making rotation smoother and more sensitive.

[0085] 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 closing the fire sand, preventing it from being released prematurely. The structural design of the switch plate 42 ensures that it can tilt quickly when driven by the rotating shaft 41, releasing the fire sand covering the fire source, thereby achieving the effect of extinguishing the fire.

[0086] The power impeller 43 is installed at both ends of the rotating shaft 41, playing a key driving role. The power impeller 43 is located in the water flow channel. When a fire occurs, water flows through the water inlet pipe 3 into the fire extinguishing system, pushing the power impeller 43 to rotate. The impeller starts to rotate at high speed under the action of 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.

[0087] Through this design, the water flow not only cools down during the extinguishing process, but also becomes the key power source to drive the switch assembly 4 to start. With the tilting of the switch plate 42, the fire sand quickly pours through the holes of the partition plate 22 onto the fire source, playing a role in isolating oxygen and suppressing the flame. The entire process is driven by water flow, without the need for external energy, ensuring the efficiency and reliability of the system, especially in emergency situations, which can quickly start the fire extinguishing mechanism.

[0088] The power impeller 43 is designed as a spherical shape, and the radius of the spherical shape is set to be consistent with the radius of the water inlet channel 24, to ensure the efficiency of the power impeller 43 rotation, so that the switch assembly 4 can release the fire sand more quickly.

[0089] As shown in Figure 8, the rotating assembly 5 is a key component of the automatic fire curtain device, responsible for quickly deploying the curtain to isolate the fire source when a fire occurs. This assembly is composed of a rotating shaft 51, a curtain body 52, a buffer block 53 and a gravity ball 54, etc. The design and cooperation of each component ensure the efficient operation of the system.

[0090] The rotating shaft 51 is the core component of the rotating assembly 5, installed in the hollow groove of the fixed block 11. Its main role is to provide a stable rotating fulcrum, so that the curtain body 52 can be quickly deployed in emergency situations. When the system is triggered, the rotating shaft 51 begins to rotate, driving the curtain to be quickly released, forming a protective isolation layer.

[0091] The curtain body 52 is located outside the rotating shaft 51, and its material is a glass fiber cloth coated with silicone rubber. This combination of materials has excellent high-temperature resistance and flame retardant effect, ensuring that it can maintain strength and play an isolation role in a high-temperature fire environment. The softness of silicone rubber combined with the toughness of glass fiber makes the curtain flexible when it is deployed to cover around the parking space, while also having strong wear resistance and tear resistance, prolonging the service life of the curtain.

[0092] To ensure the smoothness and accuracy of the curtain deployment, the rotating assembly 5 also designs a buffer block 53. The buffer block 53 is installed at the outermost end of the curtain body 52, with a trapezoidal cross-section, designed to increase the stability of the curtain edge. When the curtain is quickly deployed, the trapezoidal buffer block 53 can effectively disperse the impact force during deployment, preventing excessive vibration or damage to the curtain due to rapid deployment.

[0093] The gravity balls 54 are installed at both ends of the buffer block 53, made of high-density material, with a rubber layer wrapped around the outside. The main function of the gravity balls 54 is to provide additional inertial force during the deployment of the curtain, ensuring that the curtain can smoothly and quickly cover the fire area. The design of the rubber layer enhances the durability of the gravity balls 54 and avoids hard impact on surrounding objects when the curtain is deployed.

[0094] In the working process of the application, the new energy vehicle is parked on the application parking space 7. Once a spontaneous combustion fire occurs,

[0095] The smoke alarm and fire alarm immediately send out an alarm, the alarm device controls the electromagnetic block 13 to generate magnetism, so that the battery block attracts the control block 15 to overcome the elastic force of the supporting spring 14 to contract, and the gravity ball 54 can freely fall;

[0096] During the rapid falling of the gravity ball 54, the curtain body 52 is also brought down, and the buffer effect of the buffer block 53 reduces the rebound and ensures the accuracy of the falling position. As a result, the four rotating assemblies 5 operate simultaneously to isolate the application parking space 7, reducing air circulation on the one hand and avoiding the spread of the fire on the other hand;

[0097] The water inlet pipe 3 rapidly transports water or liquid fire extinguishing agent under the action of the control pump. The water enters the water inlet channel 24 through the water inlet pipe 3 and drives the power impeller 43 to rotate, and then enters the annular water spraying flow channel 27 through the connecting port 26, and finally is sprayed on the new energy vehicle on fire from the water spraying port 28 for cooling and fire extinguishing.

[0098] The rotation of the power impeller 43 causes the switch plate 42 to tilt, thereby preventing the fire-fighting sand inside the mounting plate from being poured on the new energy vehicle through the hole 23. In this process, the setting of the partition plate 22 plays a role in uniformly pouring the fire-fighting sand to achieve better fire extinguishing effect. If the partition plate 22 is not set, the fire-fighting sand will be poured preferentially from the place close to the water inlet channel 24 due to the fixed route of the water flow, resulting in poor fire extinguishing effect.
