Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically an aerogel fireproof roller shutter system for underground parking garages of new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicles, an increasing number of fires are occurring in underground parking garages. The main reason is that the batteries of new energy vehicles are highly susceptible to thermal runaway, causing a rapid temperature rise and the release of combustible gases, ultimately leading to spontaneous combustion. Adjacent vehicles are easily ignited under the influence of high temperatures. While traditional fireproof roller shutters offer some fire protection, they easily lose strength and integrity at high temperatures and their temperature insulation effect is not significant. Therefore, developing a novel aerogel fireproof roller shutter system with excellent fire and explosion-proof performance and good temperature barrier capabilities is of great significance for improving fire safety in underground parking garages for new energy vehicles. Summary of the Invention

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides an aerogel fireproof roller shutter system specifically for underground parking garages of new energy vehicles, the structure of which is as follows: Figure 2 As shown. This system is mainly used in underground parking garages for new energy vehicles. Addressing the characteristics of spontaneous combustion fires in new energy electric vehicles, an intelligent and highly reliable fireproof roller shutter system has been designed. The specific implementation method of the system is as follows:

[0032] The system includes an aerogel fireproof roller shutter frame 1, a roller 2, a processor 3, a drive unit 4, a smoke detector 5, a heat detector 6, a fireproof roller shutter limiting device 7, and an aerogel fireproof roller shutter 8.

[0033] The aerogel fireproof roller shutter frame 1 is made of high-strength steel and has undergone surface fireproofing treatment. The frame has internal space reserved for installing the roller shaft 2, drive unit 4, and stop device 7. Sealing strips are provided at the top and bottom of the frame to enhance the sealing performance of the roller shutter.

[0034] A roller 2 is installed inside the frame 1 and fixed at both ends by bearings. An aerogel fireproof roller shutter 8 is wound around the roller 2 and meshes with the gear motor of the drive device 4 via gears. The rotation of the roller 2 is controlled by the drive device 4 to open and close the roller shutter.

[0035] Processor 3, the control core of the system, is installed on the outside of frame 1. Processor 3 receives signals from smoke detector 5 and heat detector 6, and analyzes the fire signals using a built-in algorithm. When a fire is confirmed, processor 3 sends a command to drive unit 4 to initiate the closing procedure of the roller shutter door.

[0036] The drive unit 4, consisting of a geared motor, is fixed to the outside of the frame 1. The output end of the geared motor passes through the frame 1 and meshes with the gear of the roller 2. The drive unit 4 drives the roller 2 to rotate according to the instructions of the processor 3, thereby realizing the opening and closing of the roller shutter door.

[0037] Smoke detector 5 and heat detector 6 are mounted on the sides of frame 1. Smoke detector 5 detects smoke signals generated by a fire, and heat detector 6 detects temperature changes generated by a fire. Their combined use improves the accuracy and reliability of fire detection.

[0038] The fireproof roller shutter has a stopping device 7 installed at the bottom of the frame 1. When the roller shutter descends to the ground, the insulating rubber 71 of the stopping device 7 contacts the ground and triggers a stopping signal. The gate valve blade 73 changes from the closed state to the open state, sending a feedback signal to the drive device 4 to stop the roller shutter.

[0039] The aerogel fireproof roller shutter 8 comprises a flame-retardant coating 81, a support layer 82, a buffer layer 83, and an aerogel insulation layer 84. The aerogel insulation layer 84 is located in the middle, with buffer layers 83 on both sides of the aerogel insulation layer 84. The support layer 82 is located outside the buffer layers 83, and the flame-retardant coating 81 is located outside the support layer 82. The surface of the flame-retardant coating 81 is covered with aerogel felt, which has excellent heat insulation performance and limiting oxygen content. When closed, the roller shutter can effectively isolate fire sources and smoke, providing better protection for personnel evacuation and fire fighting.

[0040] Power system and user interface

[0041] To ensure the system operates normally during power outages due to fires, this invention employs a storage battery as a backup power source. The following is the power system and user interface:

[0042] The power system includes a main power supply and a backup power supply. The main power supply is supplied by AC mains power, and the backup power supply is supplied by a battery. When the AC mains power fails, the battery automatically switches to supply power to the system, ensuring the normal operation of key components such as the smoke detector 5, the heat detector 6, the processor 3, and the drive unit 4.

[0043] The user interface, including a display screen, buttons, and a touchscreen, is mounted on the outside of frame 1. Operators can use the touchscreen to start and stop the aerogel fireproof roller shutter and alarm. The display screen shows the system's operating status and fire alarm information in real time.

[0044] Fire detection and linkage control

[0045] This invention ensures the accuracy and timeliness of fire detection through a dual detection mechanism using a smoke detector 5 and a heat detector 6. The following are specific implementation methods for fire detection and linkage control:

[0046] When a fire occurs, smoke detector 5 immediately emits a smoke signal and transmits it to processor 3. Upon receiving the smoke signal, processor 3 sends a detection command to heat detector 6. Heat detector 6 collects temperature data and transmits it back to processor 3. Processor 3 confirms the occurrence of a fire by comprehensively analyzing the smoke signal and temperature data.

[0047] Upon confirmation of a fire, processor 3 sends a command to drive unit 4 to initiate the closing procedure of the roller shutter door. Simultaneously, processor 3 can also be linked with other fire-fighting equipment such as alarms and smoke exhaust fans to form a complete fire protection system.

[0048] Design and performance of aerogel fireproof roller shutters

[0049] The aerogel fireproof roller shutter 8 is one of the core components of this utility model, and its design and performance directly affect the fireproof effect of the system. The following are specific implementation methods for the design and performance of the aerogel fireproof roller shutter:

[0050] Application of aerogel mats

[0051] The aerogel fireproof roller shutter 8 has an aerogel felt covering its surface, which has excellent thermal insulation properties and a limiting oxygen content. The aerogel felt can effectively isolate the heat generated by the fire source and slow down the rate of heat diffusion.

[0052] Fire resistance

[0053] Aerogel fireproof roller shutters 8 can maintain good structural stability in high-temperature environments, and their fire resistance time can reach several hours, providing sufficient time for personnel evacuation and firefighting.

[0054] Smoke isolation function

[0055] Aerogel fireproof roller shutter 8 can effectively isolate the spread of smoke when closed, reducing the harm of smoke to people.

[0056] Working principle of fireproof roller shutter limiting device:

[0057] The fireproof roller shutter stopping device 7 is an important component of this utility model. Its function is to trigger a stop signal when the roller shutter door descends to the ground. The following is a detailed implementation of the working principle of the stopping device:

[0058] 1. Triggering Mechanism

[0059] When a fire occurs, the aerogel fireproof roller shutter 8 begins to descend. When the roller shutter door descends to the ground, the insulating rubber 71 of the limiting stop device 7 contacts the ground and triggers the limiting stop signal.

[0060] 2. Signal Feedback

[0061] After the stop signal is triggered, the gate valve blade 73 changes from the closed state to the open state and transmits a feedback signal to the drive unit 4. Upon receiving the feedback signal, the drive unit 4 stops the roller shutter door from descending.

[0062] 3. Reliability Design

[0063] The limiting device 7 uses a sealing strip made of highly elastic rubber material, which can work stably under different ground conditions. At the same time, the gate valve blade 73 adopts a normally closed contact switch design to ensure the reliability of signal feedback.

[0064] The system also includes a smoke guiding structure, which is disposed on the top of the aerogel fireproof roller shutter frame 1 to guide smoke to diffuse in a designated direction.

[0065] Specifically, a smoke guiding structure is a device used to guide the diffusion of smoke generated by a fire in a specific direction, typically installed at the top or side of a fire-resistant roller shutter system. Its design purpose is to reduce the interference of smoke with personnel evacuation and firefighting operations through reasonable airflow guidance during a fire. The following are the specific design details of a smoke guiding structure:

[0066] The smoke guiding structure includes:

[0067] Deflector: The core component of the smoke guiding structure is the deflector, which is usually made of high-temperature resistant materials (such as stainless steel or fire-retardant plastic). The deflector is designed with an angle or arc to effectively change the direction of smoke flow.

[0068] Exhaust vent: An exhaust vent is connected to the end of the deflector. This vent typically leads to the garage's ventilation opening or a safe area. The exhaust vent design needs to consider wind speed and smoke concentration to ensure rapid smoke removal.

[0069] Sensors and Controllers: The smoke guiding structure is also equipped with smoke sensors and controllers for real-time monitoring of smoke concentration and flow direction. The controller can adjust the angle of the guide vanes based on the signals from the smoke sensors to optimize the smoke guiding effect.

[0070] The smoke guiding structure works on the principles of aerodynamics and thermal convection. When a fire occurs, the smoke produced by combustion rises with the hot airflow and is guided towards the exhaust port by the deflector.

[0071] The system also includes an emergency start module, which is connected to the processor 3 and automatically switches to the backup power supply when the main power supply fails.

[0072] Specifically, the emergency start module includes:

[0073] Backup Power Supply: The core of the emergency start module is the backup power supply, which typically uses high-performance batteries or supercapacitors. The backup power supply needs to have high capacity and rapid discharge capability to meet the energy needs of the fireproof roller shutter system in emergency situations.

[0074] Power switching circuit: The module includes an internal power switching circuit that can quickly switch to backup power when the main power supply fails. The switching circuit adopts a high-reliability design to ensure that power switching is completed in milliseconds.

[0075] Detection and protection circuits: The emergency start module is also equipped with a power detection circuit and an overvoltage / undervoltage protection circuit to ensure that the backup power supply operates within the normal operating range.

[0076] The emergency start module operates based on real-time monitoring of the main power supply status and a rapid switching mechanism. The following is its specific workflow:

[0077] 1. Main power monitoring: The power detection circuit inside the module monitors the status of the main power supply (such as voltage, current and other parameters) in real time.

[0078] 2. Power failure detection: When the main power supply fails or the voltage is abnormal, the detection circuit immediately transmits a signal to the controller.

[0079] 3. Rapid switching: After receiving a power failure signal, the controller immediately starts the backup power supply and switches the system load to the backup power supply through the power switching circuit.

[0080] 4. Continuous Power Supply: The backup power supply provides a continuous power supply to the fireproof roller shutter system, ensuring that the roller shutter doors can be opened or closed normally.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
