Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to a garage parking space fire water curtain sprinkler system and a control method thereof. Background Art

[0002] In recent years, with the increasing popularity of electric vehicles, fires caused by charging have become increasingly common. Because electric vehicles use large lithium-ion batteries with complex chemical compositions and voltages as high as 400V-800V, if impacts occur, a battery cell can short-circuit and heat up to dangerous levels, potentially triggering a domino effect. Other cells in the battery pack will experience the same process, with the high temperatures and combustion producing even more gases, including hydrogen and oxygen, creating a self-perpetuating cycle until the battery begins to explode and burn. Electric vehicle battery fires are extremely intense and difficult to extinguish. Each fire can leave the vehicle practically ablaze, akin to an airline crash—small in chance, but difficult to escape. Furthermore, electric vehicle fires can produce over 100 organic chemicals. Some of these gases, particularly hydrogen cyanide and carbon monoxide, are highly toxic. These gases burn at high temperatures and are difficult to cool. Extinguishing an electric vehicle fire can require over 10,000 liters of water. Traditional firefighting methods often make it difficult to access the batteries and apply cold water to the affected cells, making them difficult to effectively control.

[0003] The current fire protection system lacks a design specifically for electric vehicle charging scenarios and has the following difficulties and shortcomings: 1. Existing fire water curtain sprinkler systems are mostly used for fire separation in ordinary buildings. They mainly spray downward from the top of the parking space, with insufficient water coverage and limited cooling effect.

[0004] 2. In electric vehicle fires, especially in areas with dense charging piles, the fire can easily spread to adjacent parking spaces, causing the accident to expand. Traditional fire-fighting systems find it difficult to respond quickly and accurately control the fire.

[0005] 3. Currently, there is no fire-fighting system specifically designed for electric vehicle fire extinguishing on the market. Existing vehicle fire-fighting plans cannot be directly applied to electric vehicle charging scenarios, and there is a technical gap. Summary of the Invention

[0014] The bottom spray head is arranged on the spray fire extinguishing vehicle, and the main spray head, the side spray head and the bottom spray head form a three-dimensional water spraying network to ensure that the vehicle body can be covered by water spraying in multiple dimensions and the entire range, and the cooling effect is greatly improved, and the fire extinguishing efficiency is high.

The fire control host is linked with the smoke sensing alarm system to realize automatic response to the fire signal, and the fire control host supports automatic and manual switching.

[0020] Preferably, the electromagnetic valve control button can also be in the form of a touch screen button and is arranged on the operation interface of a multi-line control panel, and the corresponding main pipeline electromagnetic valve and branch pipeline electromagnetic valve are turned on or off by operating the operation interface of the multi-line control panel.

[0039] Example The embodiment of the present invention provides a parking space fire water curtain sprinkler system in a garage, comprising a main pipe connected to the fire pipe network of a building, which is arranged in the center of the upper part of each parking space partition in the garage, and extends from the main pipe to each parking space 3 (such as Figure 2 As shown), the branch pipe can be movably placed on the sprinkler fire truck 4 at the bottom of the vehicle (as shown Figure 3 The main pipeline, constructed of galvanized steel, is laid along the main route of the building's fire protection network. Branch pipelines branch off from the main pipeline, one corresponding to each parking space 3. Sprinkler trucks 4 are detachably connected to the garage's fire hydrants. The hydrants are equipped with dual-ended valves that can switch between two water supply lines. One end of the valve is connected to the main fire water supply system, and the other end is connected to the main pipeline. By switching the valve, the main fire water supply system and the garage parking space fire water curtain sprinkler system can be supplied independently or in conjunction with each other.

[0040] Multiple water curtain nozzles are set on the branch pipes and the sprinkler fire truck 4, and the multiple water curtain nozzles are symmetrically and evenly distributed relative to the vehicle body area. The spacing of the water curtain nozzles is adjusted according to the length and width of the parking space 3, so that the multiple water curtain nozzles are symmetrically and evenly distributed relative to the vehicle body area, ensuring that the water spray is evenly covered in the longitudinal and lateral areas of the vehicle body, improving the balance of the cooling effect. The sprinkler fire truck 4 can be hung sideways on the wall of the garage when there is no vehicle fire; when a vehicle fire occurs, it can be removed from the wall, pushed and pulled to the bottom space under the chassis of the vehicle on fire, connected to the fire hydrant, and the bottom of the vehicle is sprayed to ensure that there is no dead angle in the fire extinguishing coverage. Figure 1 As shown, the water curtain nozzle includes a main nozzle 1 installed above the parking space partition for downward spraying, a side nozzle 2 installed on the side of the parking space 3 for side spraying, and a bottom nozzle 5 installed on the top of the spray fire truck 4 for upward spraying; the spray angle of the side nozzle 2 is toward the center of the parking space 3. In this embodiment, the main nozzle 1 with a diameter of 4 is installed above each electric vehicle charging pile parking space 3 (such as Figure 1 As shown, side nozzles 2 are added to the sides of charging station parking spaces 3. Their spray angles are aimed directly at the center of parking space 3. This ensures that in the event of a fire, high-temperature areas (such as the vehicle engine) are preferentially covered, preventing the spread of fire to the edges of parking space 3 due to delayed nozzle response. The center of parking space 3 can be directly targeted at the core area of ​​the vehicle, quickly forming a water mist barrier to block the fire source. The bottom nozzles 5 installed on sprinkler truck 4 combine the main nozzle 1 with the side nozzles 2 and bottom nozzles 5 to form a three-dimensional "top, middle, and bottom" water spray network, ensuring multi-dimensional coverage of the vehicle body, significantly improving cooling effectiveness and achieving high fire extinguishing efficiency.

[0041] A control box is located near each parking zone, housing a solenoid valve control unit. A main pipeline solenoid valve controls the water curtain supply for the entire parking zone. Branch pipelines are equipped with branch pipeline solenoid valves, each connected to the solenoid valve control unit.

The control box is connected to the fire control unit in the central control room via signal cables. The fire control unit receives and processes fire signals and performs coordinated system control. The fire control unit is connected to the smoke alarm system and the garage parking fire water curtain sprinkler system. Upon receiving the fire signal from the smoke alarm system, the fire control unit generates a control signal and sends it to the control box, which then controls the garage parking fire water curtain sprinkler system based on the signal. The control box contains a mode switch button for switching between remote and manual control modes, which is connected to the fire control unit. The solenoid valve control unit includes solenoid valve control buttons, which are connected to the main pipeline solenoid valve and branch pipeline solenoid valve. The control box can be linked with the fire control panel, offering multiple control modes such as remote control and manual control. The fire control panel is linked with the smoke alarm system to automatically respond to fire signals, and the fire control panel supports both automatic and manual switching.

[0042] Drain valves are installed at the lowest points of the main and branch pipes. After extinguishing a fire, drain the remaining water from the main and branch pipes through the drain valves. The drain valve specifications match the corresponding main and branch pipes to ensure smooth drainage. The drain valves can also be used to drain remaining water from the main and branch pipes during system maintenance. When extinguishing a fire or performing scheduled maintenance, close the main and branch pipe solenoid valves, open the drain valves, and drain the remaining water from the main and branch pipes to ensure the pipes are dry, avoid water contamination, and prevent water accumulation from breeding bacteria or freezing and cracking in winter. Close the drain valves after maintenance is complete.

[0043] The embodiment of the present invention further provides a control method for a garage parking fire water curtain sprinkler system, which is applied to the above-mentioned garage parking fire water curtain sprinkler system, including: automatic mode, remote manual mode, and on-site manual mode, wherein the automatic mode includes: A1. Based on the fire signal, the main and branch water pipes of the corresponding parking partition are automatically opened in sequence, and the water curtain nozzles spray fire-fighting water into the parking partition; B1. After the fire is extinguished, manually shut off the water supply to the main and branch pipes in sequence to complete the fire extinguishing. In this embodiment, after the smoke alarm system detects a fire signal and confirms a fire, it switches the fire control unit to automatic mode, opens the main pipe solenoid valve and branch pipe solenoid valve of the corresponding parking space partition, activates the garage parking fire water curtain sprinkler system, and the main nozzle 1 and side nozzle 2 simultaneously spray water to form a fire separation and cooling effect. After the fire is extinguished, the main pipe solenoid valve and branch pipe solenoid valve of the corresponding parking space partition are manually closed, and the fire control unit is switched back to manual mode, completing the fire extinguishing.

[0044] Remote manual mode includes: A2. Use the remote operation interface to open the main water supply pipe for the corresponding parking partition, and use remote control to open the branch water supply pipe. The water curtain nozzle will spray fire extinguishing water to the parking partition. When the remote manual mode is adopted in this embodiment, the solenoid valve control button also includes a touch screen button, which is set on the operation interface of the multi-line control panel. By operating the operation interface of the multi-line control panel, the corresponding main pipeline solenoid valve and branch pipeline solenoid valve are opened or closed.

[0045] B2. After the fire is extinguished, the water supply to the main pipeline and branch pipelines is shut down in sequence through the remote operation interface to complete the fire extinguishing. In this embodiment, the main pipeline solenoid valve of the corresponding parking space partition is started; the control box is adjusted to the remote control state, and the corresponding branch pipeline solenoid valve is started; the garage parking space fire water curtain sprinkler system is turned on to perform fire extinguishing operations; after the fire extinguishing is completed, the corresponding main pipeline solenoid valve and branch pipeline solenoid valve are closed through the operation interface of the multi-line control panel.

Manually open the main and branch water pipes corresponding to the parking area in sequence, and spray fire-fighting water into the parking area through the water curtain nozzles; B3. After the fire is extinguished, shut off the water supply of the main pipeline and branch pipeline in turn through manual operation on site.

[0047] In this embodiment, press the start button of the main pipeline solenoid valve control button of the corresponding parking space partition to open the main pipeline water supply; press the start button of the corresponding branch pipeline solenoid valve control button to turn on the water curtain sprinkler of the corresponding parking space partition; after the fire extinguishing is completed, press the stop buttons of the main pipeline solenoid valve control button and the branch pipeline solenoid valve control button in sequence to close the garage parking space fire water curtain sprinkler system; open the drain valve of the pipeline to drain the remaining water, and then close the drain valve, and the garage parking space fire water curtain sprinkler system returns to standby mode.

[0048] The garage parking space fire water curtain sprinkler system and control method of this embodiment are optimized for the spatial characteristics of the charging pile parking space 3 and the fire characteristics of electric vehicles. Through the combination of main pipes, branch pipes and sprinkler fire fighting vehicles 4, main nozzles, side nozzles and bottom nozzles 5 are set, which can effectively cover the multi-dimensional full range of the vehicle body of the electric vehicle charging pile parking space 3, greatly improving the cooling effect, and realizing rapid disposal of the early stage of the fire through multi-dimensional control, rapid response, precise fire control, and prevention of fire spread. It is suitable for fire prevention and fire fighting in the electric vehicle charging area in the building, effectively improving the fire extinguishing efficiency and reducing the fire risk in the electric vehicle charging area.

[0049] The system construction and installation process of the garage parking fire water curtain sprinkler system of this embodiment is as follows: On the ceiling directly above the electric vehicle charging station parking space in a certain building, a main nozzle 1 is installed according to the 4-point size specification, and side nozzles 2 are installed on the front and rear sides of the parking space. The side nozzles 2 are angled toward the center of the parking space 3. The spacing between the nozzles is adjusted according to the length and width of the parking space 3 to ensure that the water spray covers the longitudinal and width areas of the vehicle body, forming a "top, middle and bottom" three-dimensional water spray area that covers the entire range of the vehicle body.

[0050] The main pipeline is made of galvanized steel pipe and is laid along the main road of the building's fire protection pipe network. The main pipeline is installed with a main pipeline solenoid valve; the branch pipeline corresponds to each parking space 3, extends from the main pipeline, and the branch pipeline is installed with an independent branch pipeline solenoid valve.

[0051] Drain valves are installed at the lowest points of the main and branch pipes, and the valve specifications match the corresponding main and branch pipes to ensure smooth drainage.

[0052] The double-head valve of the fire hydrant is improved in design. One end of the double-head valve is connected to the main fire water supply, and the other end is connected to the main pipeline. The valve switching of the double-head valve can realize independent or linked water supply between the main fire water supply and the fire water curtain sprinkler system of the garage parking space.

[0053] A control box is installed near each partition. The control box is equipped with a power switch, a mode switch button for switching remote control / manual mode, and a solenoid valve control button. The control box and the fire host in the central control room are connected by a multi-line control panel and signal cables.

[0054] The fire host is connected to the smoke alarm system and the garage parking fire water curtain sprinkler system respectively. After the fire host receives the fire signal from the smoke alarm system, it generates a control signal and sends it to the control box. The control box controls the spraying of the garage parking fire water curtain sprinkler system according to the control signal, thereby realizing the reception, processing and system linkage control of the fire signal.

[0055] The system testing and optimization process of the garage parking fire water curtain sprinkler system of this embodiment is as follows: Water spray coverage test: Simulate the parking position of an electric vehicle, start the fire water curtain sprinkler system of the garage parking space, adjust the angle and spacing of the main nozzle 1 and the side nozzle 2, and ensure that the top and sides of the vehicle body and the area within 1 meter around the charging pile are fully covered without blind spots.

[0056] Response time test: In automatic mode, the smoke alarm is triggered and the time from the fire host receiving the signal to the water curtain nozzle discharging water is recorded, which is required to be no more than 30 seconds; in remote manual mode, the time from the fire host operation in the central control room to the nozzle discharging water is no more than 15 seconds, meeting emergency fire extinguishing needs.

[0057] Solenoid valve reliability test: The main pipeline solenoid valve and branch pipeline solenoid valve are tested for 100 switching cycles to ensure that there is no sticking or leakage. The main pipeline solenoid valve and branch pipeline solenoid valve are tightly sealed when closed and the water flows smoothly when opened.

[0058] Linkage function test: Simulate a fire scenario and test the linkage logic between the fire host in automatic state and the smoke alarm, the garage parking fire water curtain sprinkler system, and the fire pump, and verify the system's backup power switching and manual emergency operation functions under abnormal conditions such as power outages and signal transmission failures.

[0059] In an actual application scenario of a certain building, the garage parking fire water curtain sprinkler system is deployed in 32 electric vehicle charging pile parking spaces. The specific operation process is as follows: When a fire occurs in the charging pile parking space 3, the smoke alarm system is triggered, the fire host automatically switches to automatic state, immediately opens the main pipe solenoid valve and branch pipe solenoid valve of the corresponding partition, and starts the fire water curtain sprinkler system of the garage parking space. The main nozzle 1 and the side nozzle 2 spray water at the same time, forming a water wall to prevent the spread of fire and cool the burning vehicle.

[0060] If the automatic system does not respond, the corresponding solenoid valve can be remotely started from the central control room through the multi-line control panel, or the on-site personnel can switch the control box to manual mode and press the start button to start the fire water curtain sprinkler system for the garage parking space.

[0061] When fire extinguishing is completed or regular maintenance is performed, first close the solenoid valves of the main pipeline and branch pipeline, open the drain valve to drain the remaining water in the pipe to prevent water accumulation in the pipe from breeding bacteria or freezing and cracking in winter. After maintenance is completed, close the drain valve and restore the system to standby mode.

[0062] Through the implementation of the standardized installation process, refined testing and optimization, and standardized operational procedures, this garage parking fire water curtain sprinkler system can achieve efficient and reliable fire prevention and control in electric vehicle charging station parking spaces. Practical application has proven that this garage parking fire water curtain sprinkler system can control a fire within one minute of its initial stage, effectively preventing the fire from spreading to adjacent parking spaces, thus meeting fire safety requirements.
