Technical Field

[0001] This utility model relates to the field of fireproof isolation technology, and in particular to a vertical fireproof isolation device for parking spaces. Background Technology

[0002] Among existing fire prevention measures in parking lots, fixed firewalls have the problems of occupying a lot of space and having poor layout flexibility, making it difficult to adapt to different parking spaces; fire sprinkler systems are slow to respond to the initial fire situation of vehicles, especially new energy vehicle batteries, and cannot stop the horizontal spread of fire in time.

[0003] Traditional mobile isolation devices mostly use a single drive structure, which has defects such as slow deployment speed, unstable thrust, and easy tilting of the device, making it difficult to quickly form a closed isolation space, which makes adjacent parking spaces susceptible to damage. Therefore, a vertical fireproof isolation device for parking spaces is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 4 This utility model provides an embodiment of a vertical fireproof isolation device for parking spaces, comprising a frame 1, which serves as an overall supporting skeleton, and a base plate 3, which serves as a load-bearing drive system and isolation components, providing an installation reference and distributing the force on the device. Multiple load-bearing frames 4 are fixedly connected to the outside of the base plate 3, allowing for a "hidden" layout. A motor 5 is fixedly connected to the outside of the load-bearing frames 4, providing rotational power and serving as the core power source for the device's automation. A bolt shaft 6 is fixedly connected to the drive end of the motor 5, efficiently transmitting power via a helical drive. The bolt shaft 6 has a helical shape on its exterior, and a push plate 8 is rotatably connected to its exterior, converting the helical power into an unfolding force. The two ends of the push plate 8 are slidably connected to the interior of multiple adjacent grooves 7.

[0033] Both sides of the load-bearing frame 4 are provided with sliding grooves 7. These grooves are designed to prevent offset and jamming, ensuring the accuracy of linear motion. Rotating plates 9 are rotatably connected to both sides of the push plate 8. These rotating plates 9 form a four-bar linkage, distributing the force on the push plate 8. Rotating rods 10 are rotatably connected to the outside of every two rotating plates 19. These rotating rods 10 also form a four-bar linkage, distributing the force on the push plate 8. Rotating plates 11 are fixedly connected to both ends of each rotating rod 10. These rotating plates 11 also form a four-bar linkage. The four-bar linkage disperses the force on the push plate 8. One end of multiple rotating plates 11 is rotatably connected to the inside of the load-bearing frame 4. The inside of the frame 1 is fixedly connected to a roller shutter frame 12. The roller shutter frame 12 is designed to roll up and store the fireproof cloth 13, which is hidden and saves space when not in use. Multiple fireproof cloths 13 are rotatably connected to the outside of the roller shutter frame 12. The fireproof cloth 13 is designed to build a core isolation barrier that is fireproof, smokeproof, and wear-resistant. The fireproof cloth 13 can be rolled up and placed on the outside of the load-bearing frame 4. Fireproof components are fixedly connected to the outside of the fireproof cloth 13.

[0034] Reference Figure 1 , Figure 5 The fireproof component includes a flame-retardant layer 14, which is designed as the outermost layer, directly contacting external friction and initial flames. It delays the spread of fire by resisting high temperatures above 500°C and tear resistance. The flame-retardant layer 14 is made of fiberglass. One end of the flame-retardant layer 14 is fixedly connected to the outside of the fireproof cloth 13, and the other end of the flame-retardant layer 14 is fixedly connected to a smoke-proof layer 15. The smoke-proof layer 15 is designed to reflect heat radiation using the high reflectivity of aluminum foil (≥85%), reducing heat conduction to adjacent parking spaces and keeping the temperature of the unexposed surface ≤60°C. The smoke-proof layer 15 is made of composite aluminum foil.

[0035] One end of the smoke-proof layer 15 is fixedly connected to the fireproof layer 16. The fireproof layer 16 is designed as the core high-temperature resistant layer, which can withstand 1000℃ high temperature for a long time without burning, and withstand 1700℃ flame for a short time, such as battery thermal runaway. The fireproof layer 16 is made of high silica fiber cloth. The frame 1 is fixedly connected to the outside of the cross plate 2. The cross plate 2 is designed as a mechanical reinforcement: connecting the frame 1 and the base plate 3 to form an "X" shaped support structure, which enhances the overall rigidity of the device. One end of the cross plate 2 is fixedly connected to the outside of the base plate 3.

[0036] Working Principle: When smoke and temperature sensors detect a fire in the parking space, the control system triggers motor 5 to start, driving bolt shaft 6 to rotate. Since push plate 8 is threaded onto bolt shaft 6 and its ends are embedded in the grooves 7 of load-bearing frame 4, the rotational motion of bolt shaft 6 is converted into linear outward movement of push plate 8 along the axial direction. Rotating plates 9, hinged on both sides of push plate 8, swing synchronously, causing rotating rod 10 to translate laterally, causing rotating plates 11 at both ends to unfold outward around their hinge points with load-bearing frame 4, forming a four-bar linkage. This structure not only distributes the force on push plate 8 and prevents tilting, but also expands the effective pushing range through "swinging + translation." At this time, the fireproof cloth 13, pre-rolled outside the load-bearing frame 4, is rapidly laid flat and falls around the parking space from its rolled-up state under the direct pushing force of push plate 8 and the auxiliary force of the connecting rod. Because multiple load-bearing frames 4 are distributed along the four sides of the parking space, and each motor 5 operates synchronously, it ensures that the fireproof cloth 13 on all four sides unfolds simultaneously, forming a closed vertical isolation wall. Among them, the spiral structure of the bolt shaft 6 ensures the stability of the thrust, the slide groove 7 constrains the movement direction of the push plate 8, and the four-bar linkage optimizes the force. The three work together to achieve the rapid switching of the fireproof cloth 13 from "storage to isolation". With the help of mechanical linkage, the spread of fire is effectively blocked, taking into account both structural compactness and operational reliability.

[0037] When the fireproof cloth 13 is laid out flat by the push plate 8, the three-layer structure forms complementary protection: the fireproof layer 16, made of high-silica fiber cloth, directly resists open flames exceeding 1000℃, preventing flame penetration with its non-combustible properties and ensuring a fire resistance limit of ≥1 hour; the smoke-proof layer 15, made of composite aluminum foil, reflects heat radiation with high reflectivity, controlling the temperature of adjacent areas within 60℃, while also blocking the spread of toxic fumes through the sealing properties of the aluminum foil; the flame-retardant layer 14, made of glass fiber, not only assists in flame retardancy and slows down the fire, but also adapts to the mechanical deformation of "rolling-unrolling" through its wear-resistant properties, reducing damage and extending its lifespan. The three layers work together in a synergistic manner from high temperature resistance and smoke and heat insulation to wear resistance, allowing the fireproof cloth 13 to combine flexibility and durability when constructing a vertical barrier, effectively blocking the spread of fire.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
