[0007] Compared with existing technologies, the beneficial effects of this application include: the fire blanket is installed on the ceiling, which makes full use of the parking space and facilitates the direct extinguishing of parking space fires; the overall coverage method can quickly extinguish parking space fires without the need for multiple people to rush around, thus quickly eliminating the threat of parking lot fires and greatly ensuring the safety of car owners and the property and personal safety of the building.

[0008] As an improvement to the above technical solution, the lower edge of the cylindrical casing is provided with a circumferentially extending frame or a thickened skirt.

[0009] As an improvement to the above technical solution, it also includes at least two temporary pull-out strips. One end of the temporary pull-out strip is used to connect to the mounting frame, and the other end is connected to the upper end of the cylinder or the top cover plate. The temporary pull-out strip is used to control the top cover plate to sink relative to the cylinder with a lag. The temporary pull-out strip is provided with a narrowed section for being broken off by the cylinder when it expands and falls. The temporary pull-out strip is used to reduce the kinetic energy of the fire blanket's fall.

[0010] As an improvement to the above technical solution, the temporary pull-out strip is connected to the top cover piece via a snap fastener.

[0011] As an improvement to the above technical solution, the mounting frame is provided with a first wire bundle hole and a second wire bundle hole that are spaced apart vertically. The concentrated end of the multiple wires is used to pass through the first wire bundle hole and the second wire bundle hole.

The first hook is used to hook the first hook. The concentrated end of the support line is used to pass through the fire blanket to connect to the mounting frame when the fire blanket is not approaching the mounting frame. The outer ends of the multiple support lines are used to hook the first hook after the fire blanket approaches the mounting frame to support the fire blanket.

[0015] As an improvement to the above technical solution, a hanging plate is mounted on the upper end of the mounting bracket, and multiple hooks are arranged on the hanging plate along the circumference. The concentrated end of the support line is used to hook the corresponding hook.

[0016] As an improvement to the above technical solution, the mounting frame includes a ceiling bracket and a body frame that can be detachably connected to the ceiling bracket. The ceiling bracket is used to connect to the building structure with screws. A cavity is formed between the ceiling bracket and the body frame.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides a parking space fire extinguishing device, including a mounting frame 100, a fire blanket 200, support wires 300, a fire sensor, and a wire cutter. The mounting frame 100 is used to connect to the building structure above the parking space 500, such as the roof / ceiling, suspended ceiling, or canopy. The fire blanket 200 includes a cylindrical circumference 210 and a top cover 220. The cylindrical circumference 210 and / or the top cover 220 are provided with detection holes. Multiple support wires 300 are distributed circumferentially around the central axis of the fire blanket 200. The concentrated end 310 of the support wires 300 is used to pass through the wire hole 221 in the middle of the top cover 220 and then connect to the mounting frame 100. The outer connecting ends of the support wires 300... 320 is used to bypass the lower edge of the cylinder 210 and connect to the mounting bracket 100, so that the cylinder 210 supports the multiple support wires 300 in a retracted posture. The fire sensor is set on the mounting bracket 100 or the fire blanket 200. The fire sensor includes a smoke detector and an infrared sensor. The fire sensor is used to detect the fire information (i.e., smoke and temperature information, etc.) transmitted by the detection hole to determine whether there is a fire in the parking space 500. The wire cutter is set on the mounting bracket 100. The wire cutter is used to be triggered when the fire sensor detects the fire information to cut the multiple support wires 300 simultaneously. The fire blanket 200 is used to cover the parking space 500.

[0032] Reference Figure 1 , Figure 6 It is understandable that the size of the parking space 500 and the size of the fire blanket 200 are designed to correspond. When the fire blanket 200 ideally covers the parking space 500, the lower edge of the cylinder 210 is aligned with the parking space frame line 510.

[0033] Reference Figure 1 , Figure 3 and Figure 5In this invention, multiple support wires 300 are provided. One end of each support wire 300 is concentrated in the central area of ​​the fire blanket 200 (i.e., the wire hole 221 of the cover plate 220). Therefore, this end of the support wire 300 is called the concentrated end 310, and the other end is called the external connection end 320. The concentration of one end of the multiple support wires 300 corresponds to the central area of ​​the fire blanket 200, providing strong support for the lightweight cover plate 220 and facilitating the installation of the following flexible hose 223.

[0034] Understandably, the fire blanket 200 is made of flame-retardant and high-temperature resistant materials and is as soft as a regular blanket. The circumference 210 is foldable and retractable. The fire blanket 200 can cover objects in a soft manner so as to quickly cover the fire source and isolate the oxygen supply, so that the fire can be extinguished quickly in a low oxygen content.

[0035] Fire blankets 200 can be made of fiberglass, or even coated with silicone, tin, or flame retardant layers (such as aluminum hydroxide). The thick coating ensures that the hardness of the fire blanket 200 is not significantly affected, while improving the airtightness of the fire blanket 200. These coatings can withstand 550-600℃ for a long time, and 1000℃ for a short time (a few minutes). The melting point is about 1200℃. It does not burn or melt when exposed to fire. It can be folded for easy and quick unfolding.

[0036] Fire blankets 200 can also be made of ceramic fibers, such as aluminosilicate ceramic fibers, with a long-term operating temperature of 1000–1260℃ and a short-term operating temperature of up to 1600℃, and a density of only 0.1–0.3 g / cm³. 3 It is lighter than fiberglass and has better heat insulation. In addition, the fire blanket 200 can also be woven from aramid fibers and other materials.

[0037] Wire cutters are scissors, guillotines, or cutters used to cut the multiple wire supports 300. Therefore, wire cutters can include a fixed blade, a moving blade, and a wire-cutting power component (motor, cylinder, hydraulic cylinder). The wire-cutting power component drives the moving blade to engage or cut the fixed blade to cut / sever / sever the multiple wire supports 300. Wire cutters can also include a rotary blade and a wire-cutting motor, with the motor driving the rotary blade to rotate and cut the multiple wire supports 300.

[0038] Maintain the wire cutters regularly to keep them clean and sharp.

[0039] Reference Figure 1 , Figure 3 It is understandable that the support wire 300 supports the fire blanket 200, but also keeps the support wire 300 taut, making it easier for the support wire 300 to be cut / chopped / severed; that is, the support wire 300 "supports" the fire blanket 200, and the fire blanket 200 "tauts" the support wire 300, and the two effects complement each other.

[0040] In fire detection, when the concentration of smoke particles is greater than or equal to the detection threshold, the smoke detector initially confirms the presence of a fire in parking space 500; when the infrared temperature detector is greater than or equal to the detection threshold of 60℃, or when the ambient temperature rises continuously within a time period T (e.g., within 1 minute), the infrared sensor (including the comparator) initially confirms the presence of a fire in parking space 500. Therefore, when both the smoke detector and the infrared sensor confirm the presence of a fire, the fire detection sensor confirms the actual presence of the fire, and both the smoke detector and the infrared sensor are activated, causing the power supply to the wire cutter to be activated, and the wire cutter to perform the wire cutting action (engaging / swinging, etc.).

[0041] Some configurations also include a controller, such as a common microcontroller or PLC. The fire sensor and the wire cutter are electrically connected to the controller, which receives the input from the fire sensor and outputs control signals to the wire cutter (i.e., controls the conduction of the wire cutter's power supply circuit).

[0042] Smoke detectors can use photoelectric sensors or ionization sensors. Smoke particles are typically 0.5-10 micrometers in size. Photoelectric sensors are more sensitive to larger particles (visible smoke particles, i.e., larger particles produced by smoldering) in the 0.5-10 micrometer range, while ionization sensors are sensitive to smaller particles. On the other hand, automobile exhaust is mainly CO, whose particles are typically smaller, 0.1-1 micrometer, primarily in the 0.1-0.5 micrometer range, which is 2-10 micrometers outside the sensitivity range of smoke detectors (both photoelectric and ionization sensors).

[0043] Furthermore, fires are typically accompanied by a sustained rise in ambient temperature, a characteristic not found in vehicle exhaust. Additionally, vehicle exhaust temperatures are ≤40℃, and the body temperature of a normal vehicle (even a recently parked vehicle) is ≤45℃. If the ignition sensor cannot detect a temperature change (or the detected value does not exceed the threshold), and the smoke particles are relatively small, the ignition sensor's triggering will be suppressed.

[0044] Regularly maintain the fire detection sensor and keep it clean.

[0045] On the other hand, one or more detection holes and one or more fire sensors are provided.

[0046] In practice, vehicles may not be parked perfectly centered, with parts of the vehicle's perimeter above the parking space frame 510. When the fire blanket 200 is lowered, certain sections of the cylinder 210 may slip down along the vehicle's perimeter. In some designs, to ensure the stability of the fire blanket 200's downward coverage and effectively guarantee complete coverage of the entire parking space 500 / the entire vehicle, refer to... Figure 1 , Figure 4 and Figure 5The lower edge of the cylindrical casing 210 is provided with a circumferentially extending frame or thickened skirt, such as a ceramic fiber frame with a diameter of φ10-20mm, to ensure fire resistance. It is slightly harder than the fire blanket 200, with a hardness similar to that of a rubber strip, so that the lower end of the cylindrical casing 210 can stably cover downwards in a frame posture, and the cylindrical casing 210 is not easily blocked. In addition, the frame material is also relatively lightweight and is not easy to damage vehicles.

[0047] In some designs, the lower end of the cylindrical circumference 210 is thickened compared to the upper end, such as by adding a thicker skirt, so that the cylindrical circumference 210 is less likely to be blocked and can stably cover the vehicle.

[0048] Ideally, it also includes a line-crossing detector, such as an ultrasonic sensor or a radar detector. The line-crossing detector is used to detect whether the parking space frame line 510 is obstructed by a vehicle, that is, to detect whether a vehicle is crossing or extending beyond the line. The line-crossing detector can be connected to a buzzing alarm, such as an alarm that reads "Vehicle crossing or extending beyond the line, at or beyond the effective range of the fire blanket 200".

[0049] In some settings, security guards patrol or record video surveillance, reminding car owners that "vehicles should not cross or extend beyond the line to avoid exceeding the protection range of the fire blanket 200"; and / or, relevant notices are posted near the parking space.

[0050] An understandable equivalent is that the multiple support wires 300 can directly support the fire blanket 200. Alternatively, the multiple support wires 300 can be connected at one end to the cantilever end of a support plate, with the other end of the support plate hinged to the mounting bracket 100 or the building structure. The support plate directly supports the cylindrical section 210 of the fire blanket 200, and the support wires 300 support the top cover 220. Disconnection of the support wires 300 releases the support plate, allowing the fire blanket 200 cylindrical section 210 to be released.

[0051] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments of this utility model, at least two temporary tension and release strips 400 are also included. One end of the temporary tension and release strip 400 is used to connect to the mounting bracket 100, and the other end is used to connect to the upper end of the cylinder 210 or the top cover 220. The temporary tension and release strip 400 is used to control the top cover 220 to sink relative to the cylinder 210 with a lag. The temporary tension and release strip 400 is provided with a narrowed section 410 for being pulled off by the cylinder 210 when it unfolds and falls. The narrowed section 410 is the stress concentration point of the temporary tension and release strip 400. The temporary tension and release strip 400 is used to reduce the kinetic energy of the fire blanket 200 falling.

[0052] Reference Figure 1 , Figure 4 and Figure 5The parking space fire suppression system includes fire response procedures, wire cutting and conduit placement procedures, energy reduction and lowering procedures, and parking space covering procedures. This system is also used to extinguish fires in parking spaces up to 500 square meters, quickly and quietly suppressing the blaze.

[0053] Fire response steps: When a parked vehicle and / or a charging vehicle in parking space 500 catches fire (smoldering or open flame), it generates smoke particles (mainly ≥1.5 micrometers, with a few 0.3-1.5 micrometers), and the ambient temperature continues to rise. The actual temperature of the fire generally exceeds 60°C. Therefore, the smoke detector and infrared sensor detect the fire and energize the wire cutter.

[0054] In the process of cutting the wire and releasing the tube, the wire cutter simultaneously cuts / chops / severs the multiple support wires 300, causing the tube circumference 210 to lose its support. The top cover 220 is temporarily suspended by the multiple temporary tension and release bars 400 (i.e., the multiple temporary tension and release bars 400 overcome the weight of the top cover 220). The tube circumference 210 falls downwards in a gradually unfolding manner, while the top cover 220 does not fall temporarily. After the tube circumference 210 is fully unfolded, it will continue to fall downwards.

[0055] Assuming a height of 1.7-2 meters for a large SUV, the cylinder circumference 210 can be set to 2 meters. During the initial settling of the fire blanket 200 (the first 2 meters of drop), only the cylinder circumference 210 descends. Since the building height is generally 2.8-3.3 meters, in the initial stage of the settling, the cylinder circumference 210 begins its 1.3-meter drop (3.3 meters = building height - 2 meters vehicle height) at zero speed. This 1.3-meter drop allows the woven cylinder circumference 210 to acquire relatively low kinetic energy, but this energy is sufficient for the cylinder circumference 210 to begin covering the vehicle and is less likely to damage it. In the later stage of the initial settling (0.7 meters = 2-1.3 meters), the cylinder circumference 210 uses the kinetic energy gained in the initial stage to stably cover the vehicle, preventing it from stopping due to potential obstruction from the vehicle's exterior walls.

[0056] In rare high-rise, low-vehicle scenarios, such as low-slung sedans typically being 1.15-1.3 meters tall, lower than the 1.4-1.5 meters of regular sedans, and some buildings reaching 3.8 meters, the design of the 400mm temporary release strip at 2.7 meters (3.8-1.1 meters) above these sedans is particularly ingenious. On the other hand, the 210mm circumference is a relatively lightweight fiber component, and its descent is an unfolding process rather than ideal free fall. Furthermore, the kinetic energy gained at 2 meters is relatively small, which the vehicle's outer shell rigidity can easily withstand (see the vehicle's outer shell rigidity's resistance to wind resistance).

[0057] In the energy reduction and descent step, the cylinder 210, which is about to continue falling, uses its kinetic energy and the weight of the fire blanket to break the temporary tension release bar 400, allowing the top cover 220 to begin to sink. This allows the cylinder 210 to continue sinking after reducing or even eliminating the inertia of the fall, thus preventing the fire blanket 200 from gaining high energy with a fall distance of 3-3.8 meters, preventing the fire blanket 200 from damaging the vehicle (in high-rise and low-vehicle scenarios), and preventing the cylinder 210 from scraping the vehicle's outer wall at high speed.

[0058] Ideally, the inner side of the fire blanket 200 is coated with a tin layer or a flame retardant layer (such as aluminum hydroxide). When the cylinder 210 settles and wipes against the outer wall of the vehicle (i.e., when the vehicle is pressing on the wire or partially exposed), the cylinder 210 is less likely to scratch the vehicle.

[0059] In the parking space covering process, the lower end of the cylinder 210 touches the ground, and the fire blanket 200 and the ground (floor) together define a relatively enclosed space to extinguish a fire in parking space 500. This enclosed space is difficult to replenish with oxygen; combined with the oxygen consumption of smoke, the oxygen content inside the fire blanket 200 can be ≤2%, far lower than the oxygen content required for combustion (most fuels require ≥15%, gasoline ≥14%, and the most flammable hydrogen and white phosphorus require ≥5%). Furthermore, the top cover 220 gradually softens and adheres to the vehicle roof, and the cylinder 210 gradually softens and adheres to the surrounding vehicle, further extinguishing any potential fire. During this process, the enclosed space is further compressed, and the actual oxygen content becomes almost zero. It is understandable that when the fire blanket 200 softens and adheres to the vehicle, the detection holes, wiring holes 221, and the gaps where the fire blanket 200 touches the ground are designed to allow for air venting, ensuring that the fire blanket 200 remains softly attached to the vehicle. Deflating means that air / oxygen is not allowed to be added to the fire blanket 200.

[0060] Understandably, the cost of a parking space fire suppression system (total cost of mounting bracket 100, fire blanket 200, fire sensor, and wire cutter, etc.) reaches or even exceeds 400 yuan. In practice, the number of parking space fire suppression systems is designed according to the parking lot's budget. Parking space fire suppression systems are preferentially installed in tram parking spaces (500 spaces).

[0061] On the other hand, notices are posted at tram parking spaces 500, or at charging heads / boxes, requiring charging cables to be laid close to or nearly close to the ground across the parking space frame 510 to prevent the fire blanket 200 from being excessively raised. Furthermore, the fire blanket 200 is also used to fill its interior with foam extinguishing agent, which is used to cover the fire source and seal the gap between the fire blanket 200 and the ground.

[0062] Compared with the prior art, the beneficial effects of this application include: the fire blanket 200 is installed on the ceiling, which makes full use of the parking space 500 space and facilitates the direct extinguishing of the fire in the parking space 500; by covering the entire space, the fire in the parking space 500 can be extinguished more quickly without the need for multiple people to rush around, thus quickly eliminating the threat of fire in the parking lot and greatly ensuring the safety of car owners and the property and personal safety of the building.

[0063] Ideally, the fire sensor is connected to an alarm, which is suitable for sound and light alarms to detect the presence of a fire, facilitating on-site personnel to begin evacuation, firefighting, and / or rescue, and enabling parking lot security to respond quickly.

[0064] In the optimal design, with the temporary release strip 400 combined with the tube 210, the tube 210 is divided into a front lobe and a rear lobe. Both the front and rear lobes are integrally formed with the top cover 220 at their upper ends. The front and rear lobes partially overlap, so that the tube 210 forms a closed tube when covered. The tube 210 is divided into two lobes, which allows personnel inside the train to still open the doors after the fire blanket 200 covers the train. That is, when the doors are opened, the front lobe and / or the rear lobe can be lifted, allowing personnel inside the train to escape. On the other hand, after the fire in the car 500 is extinguished, it is convenient for on-site personnel to temporarily lift the front lobe and / or the rear lobe to check whether anyone is inside the car.

[0065] In the process of cutting the thread and releasing the tube, the pulling of the release strip 400 is temporarily slowed down to allow the front and back petals to unfold and form a closed tube 210, which is then dropped in the form of the tube 210.

[0066] In some embodiments of this utility model, the cylindrical circumference 210 is divided into a front lobe and a rear lobe. Correspondingly, the circulation channel 211 is essentially divided into two sections, and each section is connected to the transition channel 222 through different branch channels 224.

[0067] Reference Figure 1 , Figures 3 to 5 In some embodiments of this utility model, the mounting bracket 100 is provided with a first bundle hole 121b and a second bundle hole distributed vertically at intervals. The concentrated end 310 of the multiple support wires 300 is used to pass through the first bundle hole 121b and the second bundle hole. A taut multi-strand rope 330 is formed between the first bundle hole 121b and the second bundle hole. The wire cutter is suitable for cutting the multi-strand rope 330, effectively solving the problem of synchronous cutting and synchronous quick cutting of the multiple support wires 300. In the fire protection installation step, after the multiple support wires 300 are fixed, they support the fire blanket 200, and a multi-strand rope 330 composed of the multiple support wires 300 is formed between the first bundle hole 121b and the second bundle hole. In the wire cutting and drum release step, the wire cutter intermittently / cuts / severs the multi-strand rope 330, so that the multiple support wires 300 release the fire blanket 200 synchronously and quickly, and the drum circumference 210 unfolds in an orderly / flat manner. (Refer to...) Figure 1 , Figures 3 to 6The hanging plate 121 and the main body frame 120 are respectively provided with a first wire bundle hole 121b and a second wire bundle hole, and the upper end face of the main body frame 120 is used to arrange wire cutters.

[0068] Reference Figure 3 To make the illustration clearer, the central end 310 of part of the support line 300 is omitted from the display.

[0069] Reference Figure 1 , Figures 3 to 5 In some embodiments of this utility model, the mounting bracket 100 is provided with a source connector 150 for connecting the extinguishing agent, and the central area of ​​the cover plate 220 is provided with a transfer channel 222. The transfer channel 222 is connected to a hose 223, such as a snake tube, a throat tube, or a corrugated tube. The hose 223 is used to connect to the source connector 150 through a quick connector. The fire blanket 200 is provided with a plurality of branch channels 224 distributed around the circumference of the transfer channel 222. The branch channels 224 are connected to the transfer channel 222 and are provided with a first discharge hole that discharges the extinguishing agent toward the inside of the fire blanket 200. The parking space fire-fighting method also includes a spray fire-fighting step. When the fire blanket 200 covers the parking space 500, the foam extinguishing agent source connected to the starter connector 150, such as a high-pressure foam extinguishing agent storage tank or a foam fire extinguisher, is activated. The first discharge hole of the diversion channel 224 discharges the foam extinguishing agent, which covers the vehicle to further ensure fire extinguishing. The gap between the lower end of the foam extinguishing agent sealing cylinder 210 and the ground is sealed. In the energy reduction and lowering step, when the top cover 220 settles, the hose 223 extends.

[0070] Understandably, quick couplings, as common knowledge, can be applied to different media in various fields, such as air, oil, and water. A quick coupling includes a first end and a second end that detachably snaps onto the first end. A quick coupling is a connector that allows for the connection or disconnection of pipelines without tools. Although on-site safety is paramount and vehicle safety secondary when a vehicle catches fire, foam extinguishing agents have a low water content and are less likely to damage the vehicle. Furthermore, the source connector 150 connects to the extinguishing agent via a solenoid valve. After the fire blanket 200 releases the extinguishing agent for a certain period, such as 2 minutes, if the fire sensor no longer detects a fire, the solenoid valve shuts off the continued output of the foam extinguishing agent.

[0071] In this invention, the source connector 150 and the hose 223 are respectively provided with the first end and the second end. Because the fire blanket 200 itself is a foldable soft body similar to a blanket, after the fire blanket 200 is installed, the second end can be grasped by the top cover 220 to allow the second end to be inserted into or removed from the first end. Of course, after the fire blanket 200 settles to extinguish the fire, the fire blanket 200 moves away from the source connector 150, at which point the first end and the second end can be more easily separated.

[0072] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this utility model, the lower edge of the cylindrical casing 210 is provided with a circumferentially extending annular channel 211. The annular channel 211 is connected to the transfer channel 222 through the branch channel 224. The annular channel 211 is provided with a plurality of second discharge holes distributed at intervals along its axial direction. The second discharge holes are adapted to discharge the extinguishing agent to the inside of the cylindrical casing 210.

[0073] In some configurations, the control frame is essentially a circulation channel 211, and the control frame is embedded in the lower edge of the cylinder 210, that is, the outer wall of the control frame is bonded with refractory fiber.

[0074] In some configurations, there is no surrounding frame, and a circulation channel 211 is provided at the lower edge of the cylindrical circumference 210, which is essentially a thickening of the lower edge of the cylindrical circumference 210; that is, there can be a thickened skirt with a circulation channel 211.

[0075] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments of this utility model, the mounting frame 100 is provided with a first hook 122, and the outer end 320 of the support line 300 is provided with a second hook 321. The first hook 122 is used to hook the first hook 122. The concentrated end 310 of the support line 300 is used to pass through the fire blanket 200 to connect to the mounting frame 100 when the fire blanket 200 is not approaching the mounting frame 100. The outer end 320 of the multiple support lines 300 is used to hook the first hook 122 after the fire blanket 200 approaches the mounting frame 100 to support the fire blanket 200, effectively solving the problem of convenient installation of the large object, the fire blanket 200. Specifically, in the fire protection installation process, before fixing the mounting bracket 100, the fire blanket 200 is not brought close to the mounting bracket 100. The concentrated end 310 of the support wire 300 is passed upward through the fire blanket 200 and connected to the mounting bracket 100. Then, while keeping the concentrated end 310 of the support wire 300 through the blanket and connected to the bracket (while keeping the support wire 300 drooping), the mounting bracket 100 is fixed. Then, the fire blanket 200 is brought close to the mounting bracket 100, and the outer connection end 320 of the support wire 300 is hooked onto the mounting bracket 100.

[0076] Understandably, the final actual length of the support line 300 is determined by cutting or extending the support line 300 according to the result of "supporting the fire blanket 200". Cutting can be done by cutting the line and then attaching a second hook 321, or by tying a knot to shorten the line.

[0077] Furthermore, during the fire protection installation process, after the support cable 300 is connected, the temporary release bar 400 is hooked onto the mounting bracket 100. When normally disassembling and inspecting the parking space fire extinguishing device, first release the connection between the temporary release bar 400 and the mounting bracket 100, and then release the connection between the external connection end 320 of the support cable 300 and the mounting bracket 100.

[0078] Reference Figure 1 , Figures 3 to 5 In some embodiments of this utility model, a hanging plate 121 is mounted on the upper end of the mounting bracket 100. The hanging plate 121 has multiple hooks 121a arranged circumferentially, and the concentrated end 310 of the support line 300 is used to hook the corresponding hooks 121a. During the fire protection installation process, the concentrated end 310 of the support line 300 is provided with a ring, which is used to hook the hanging plate 121, facilitating quick and easy fixation of the concentrated end 310 of the support line 300. After the concentrated end 310 of the support line 300 hooks onto the mounting bracket 100, the mounting bracket 100 can be fixed and the fire blanket 200 moved upwards while maintaining the suspension of the support line 300.

[0079] In some embodiments of this utility model, the temporary release strip 400 is connected to the top cover 220 via snaps, similar to snaps commonly used in clothing. The snaps are easy to press and pull apart, and the combined force of multiple snaps is sufficient to secure the top cover 220. Therefore, in this utility model, the temporary release strip 400 is easy to replace and disassemble, and the fire blanket 200 can be reused multiple times, requiring only the replacement of the temporary release strip 400 each time.

[0080] The upper end of the temporary release strip 400 is hooked onto the mounting bracket 100, and the lower end is connected to the fire blanket 200 via snap fasteners.

[0081] In practice, the parking spaces 500 are compact, and the fire extinguishing devices for each parking space are also arranged compactly. Therefore, each fire extinguishing device can only be installed below it and then raised to the ceiling. In addition, the mounting bracket 100 needs to reserve a certain space in the cavity 140 to install wire cutters, fire extinguishing agent supply pipes, and mounting plates 121, etc.; in addition, the central end 310 of the cable 300 needs to pass through the cavity 140 and connect to the structure inside the cavity 140.

[0082] To address the ease of fixing the centralized terminal 310 of the cable 300, and other related issues, refer to... Figure 1 , Figure 4 and Figure 5In some embodiments of this utility model, the mounting frame 100 includes a ceiling bracket 110 and a detachable main frame 120 connecting the ceiling bracket 110. The ceiling bracket 110 is used for screw connection to the building structure, such as the most common wall expansion screws. A cavity 140 is formed between the ceiling bracket 110 and the main frame 120. The cavity 140 is provided with the concentrated end 310 of the cable 300 and the wire cutter. In this utility model, the ceiling bracket 110 and the main frame 120 are detachable, which facilitates the first fixing of the ceiling bracket 110 to the suspended ceiling. The ceiling bracket 110 is unloaded and easy to install. Then, after the concentrated end 310 of the cable 300, the wire cutter and other components are installed on the upper end of the main frame 120, the main frame 120 and its components are integrally fixed to the ceiling bracket 110, thus solving the installation problem of the concentrated end 310 of the cable 300, the wire cutter and other components.

[0083] Reference Figure 1 , Figures 3 to 6 The main frame 120 is equipped with a hanging plate 121. The hanging plate 121 is provided with a first wire harness hole 121b. The multi-strand rope 330 between the first wire harness hole 121b and the second wire harness hole is the multi-strand rope 330 between the main frame 120 and the hanging plate 121.

[0084] Reference Figure 1 , Figure 4 and Figure 5 Furthermore, the main frame 120 is a hollow plate. The multiple support lines 300 are used to align the concentrated end 310 with the parking space frame line 510 when the mounting frame 100 is not disassembled. This allows the hollow holes of the main frame 120 to allow workers to mark the drilling points on the building structure, i.e., the marking points for the wall holes into which the expansion screws are inserted.

[0085] The parking space fire protection method includes a fire protection installation step prior to the fire response step. When the main frame 120 and the ceiling frame 110 are connected as a whole, for example, when they are connected by only three or four screws, the outer end 320 of the multiple support wires 300 is connected to the main frame 120, and the concentrated end 310 of the multiple support wires 300 is not connected to the main frame 120 and hangs down, so that the multiple support wires 300 are plumb and correspond to the parking space frame line 510. Then, according to the mounting holes of the ceiling frame 110, the drilling points are drawn on the building structure, or according to the rectangular distribution frame corresponding to the plumb of the multiple support wires 300, the parking space 500 is drawn.

[0086] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this utility model, the mounting bracket 100 includes at least two sets of fasteners 130 arranged in different horizontal directions. Figure 1 , Figure 4 and Figure 5The system is equipped with a set of fasteners arranged in the front-to-back direction and a set of fasteners arranged in the left-to-right direction. During the fire protection installation process, each set of fasteners 130 is used to fasten the ceiling bracket 110 in a facing manner. The main frame 120 is used to connect the fasteners 130 with screws. By setting at least two sets of fasteners 130 in different directions, the front-to-back and left-to-right movement of the main frame 120 can be restricted, and the main frame 120 can have strong installation stability.

[0087] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
