A new energy vehicle transports fire closed suppression device

Abstract

This invention discloses a fire-sealing and suppression device for transporting new energy vehicles. A flexible fireproof isolation covering component encloses the vehicle in a sealed protective space, and a tightening sealing component is used to seal the flexible fireproof isolation covering component. With the above solution, this invention can achieve all-round sealing of a single transport new energy vehicle. After a single vehicle experiences thermal runaway and catches fire, the open flame and high-temperature smoke are completely sealed within the cavity due to the presence of the flexible fireproof isolation covering component, or are discharged to a safe area by the exhaust pipe, preventing them from spreading and igniting surrounding vehicles. This fundamentally solves the core industry pain point of chain combustion during mass transportation.

Description

Technical Field

[0001] This invention belongs to the field of fire protection and security technology for new energy vehicle transportation. Specifically, it relates to a fire suppression device for vehicle-mounted fire early warning and thermal runaway suppression scenarios that can be widely used in the mass transportation of new energy vehicles by land and water. Background Technology

[0002] With the rapid development of the new energy vehicle industry, bulk container transportation of new energy vehicles has become the mainstream logistics model. As the core energy storage component of new energy vehicles, power batteries are highly susceptible to thermal runaway during long-distance transportation due to factors such as bumps and vibrations, changes in ambient temperature and humidity, micro-defects in the batteries themselves, and compression and friction. This can lead to spontaneous combustion, fires, or even explosions. Lithium battery fires are characterized by their high degree of concealment, rapid chain-like spread of thermal runaway, high reignition rate, and highly toxic fumes. Conventional firefighting methods are insufficient to completely extinguish them. Once a single vehicle catches fire, it can easily ignite multiple surrounding vehicles, causing significant property damage and safety accidents. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fire suppression, cooling and fire cut-off device for new energy vehicle transportation. This device solves the technical problems of existing transportation fire prevention devices lacking independent sealed protection space, poor chain fire suppression, and inability to adapt to batch vehicle transportation. It achieves the technical effect of independent, fully enclosed, sealed fire isolation for a single vehicle and preventing chain combustion and reignition.

[0004] To achieve the above objectives, the present invention provides a fire-sealing and suppression device for transporting new energy vehicles, comprising a flexible fireproof isolation covering component and a tightening and sealing component thereof. The flexible fireproof isolation covering component covers the vehicle in a sealed protective space, and the tightening and sealing component is used to seal the flexible fireproof isolation covering component. The flexible fireproof isolation covering component consists of a bottom portion for parking the vehicle and an upwardly foldable portion.

[0005] The flexible fireproof isolation covering component adopts a three-layer integrated hot-pressed composite structure without pinholes. From the outside to the inside, it consists of a wear-resistant and tear-resistant ceramic outer layer, an aerogel fire-resistant and heat-insulating middle layer, and a smooth flame-retardant protective inner layer. The three-layer structure is integrally hot-pressed and formed by high-temperature flame-retardant adhesive film, without seam needle holes or smoke penetration channels.

[0006] The flexible fireproof isolation covering component is equipped with a smoke exhaust duct, and a flame cut-off device is installed on the smoke exhaust duct.

[0007] The tightening and sealing assembly is located above the vehicle and includes a tightening base, a winch drive structure, a traction tightening rope, and a manual strap locking structure; the traction tightening rope is arranged at the edge of the folded portion of the flexible fireproof isolation covering assembly.

[0008] Compared with the prior art, the present invention has the following outstanding substantive features and significant progress: 1. This invention adopts a rollable multi-layer flexible fireproof covering structure, which can achieve all-round sealing of a single transport new energy vehicle. In the case of batch transportation, it forms an independent fireproof isolation cavity. After a single vehicle is thermally runaway and catches fire, the open flame and high temperature smoke are completely sealed in the cavity due to the presence of the flexible fireproof isolation covering component, or are discharged to a safe area by the exhaust pipe, and will not spread and ignite surrounding vehicles. This solves the core pain point of chain combustion in batch transportation from the root.

[0009] 2. Multi-layered composite flexible structure, balancing protection and reusability. The coating component of this invention adopts a three-layer composite structure of outer wear-resistant, middle fire-resistant, and inner scratch-resistant layers, solving the problems of traditional refractory materials being brittle, not resistant to bending, easily damaged, and easily scratching the vehicle body. It can be repeatedly rolled up and stored, and reused, significantly reducing transportation and safety costs, while perfectly protecting the vehicle paint.

[0010] 3. Compact structure, strong adaptability, and easy to popularize. This invention has a small storage volume when stored and can be rolled up for storage, without occupying transportation space; it is easy to install, simple to operate, and requires no daily maintenance. It is suitable for various new energy vehicles in land and water transportation scenarios, and has extremely high promotional value. Attached Figure Description

[0013] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0014] like Figure 1 and Figure 2The present invention discloses a fire-sealing and suppression device for transporting new energy vehicles, comprising a flexible fireproof isolation covering component 1 and a tightening and sealing component 3 thereof. The multi-layer flexible fireproof isolation covering component 1 is the core isolation and protection structure of this device, consisting of a bottom portion 11 for vehicle parking and an upwardly foldable portion 12 forming a flexible bag structure. The foldable portion 12 can be folded around the bottom portion 11. The multi-layer flexible fireproof isolation covering component 1 can be freely rolled up and stored, and during normal transportation and storage, it is rolled into a cylindrical shape, occupying minimal space. Figure 2 As shown, multiple traction tightening ropes 13 are evenly arranged around the upper edge of the multi-layer flexible fireproof isolation covering component 1. The ends of all traction tightening ropes 13 are uniformly connected to the hook position of the top hoisting drive structure 3. The hoisting drive structure 3 is automatically triggered to work, quickly pulling all the tightening ropes upwards simultaneously, causing the flexible covering bag's folded portion 12 to fold upwards as a whole, completely covering the entire vehicle. After automatically tightening to the desired position, workers can use the straps 5 to tie the flexible covering bag tightly and seal it, forming a completely sealed independent fireproof cavity. like Figure 3 The multi-layer flexible fireproof isolation covering component 1 shown adopts a three-layer composite structure design. The outermost layer is a flame-retardant and wear-resistant layer 1a, which is a wear-resistant and tear-resistant ceramicized outer layer made of aramid fiber and high-silica fiber blended fabric. The entire fabric surface is impregnated with a nano-ceramicized flame-retardant coating. At room temperature, it has high flexibility, high wear resistance, and tear resistance, and can withstand repeated bending, winding, and pulling. Under high-temperature conditions, the surface coating rapidly ceramicizes and cures, forming a dense and hard ceramic protective layer that seals the fabric weave pores. It can block open flame burning above 800℃ and high-temperature smoke penetration, while resisting external impact and friction damage. It has high strength tear resistance, wear resistance, and aging resistance, and can withstand... Damage from bumps and friction during transportation; the middle layer is a fire-resistant intermediate layer 1b, which uses an aerogel fire-resistant and heat-insulating intermediate layer as the core fire-resistant and heat-insulating layer. It adopts a glass fiber-based aerogel composite felt structure, forming a micron-level closed microporous structure inside. It utilizes the principle of microporous air heat insulation to significantly block heat conduction; the intermediate layer material has the characteristics of thermal expansion and carbonization, and quickly forms a dense carbonized barrier layer at high temperatures, further blocking the penetration of heat radiation and achieving long-term heat insulation and fireproofing; the innermost layer is a smooth flame-retardant inner layer 1c, with a flat and smooth surface, which can effectively avoid scratching the vehicle paint during the wrapping and tightening process, taking into account both fireproof performance and vehicle protection needs, and solving the defects of traditional fire-resistant cloth that is not resistant to folding, easily damaged, and easily damages vehicles.

[0015] like Figure 1 As shown, the multi-layer flexible fireproof isolation covering component 1 is connected to the flue gas duct, which can quickly extract the high-temperature flue gas and toxic flammable gas in the sealed covering cavity to a safe area. A flame cut-off device is installed on the flue gas duct. The structure of the flame cut-off device is known. The flame cut-off device can extinguish the open flame in the high-temperature flue gas.

[0016] In use, the rolled-up multi-layer flexible fireproof isolation covering component 1 is laid flat in the parking area, with the folded portion 12 stacked around the bottom portion 11. When the vehicle drives onto the bottom portion 11, the ends of the traction tightening ropes 4 are all connected to the hook position of the top winch drive structure 3. When the passive fire detection linkage drive component 6 detects thermal runaway or fire in the vehicle, it automatically triggers the winch drive structure 3 to work, quickly pulling all the tightening ropes upwards simultaneously, causing the flexible covering bag to fold upwards and the top aperture to shrink rapidly, completely covering the entire vehicle. After automatic tightening, workers can manually tighten and seal the bag along the stepped surface of the disc-type tightening base 2 using the straps 32, forming a completely sealed independent fireproof cavity.

[0017] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
