[0039] Example 1:

[0040] like Figures 1-5 As shown, a portable flame-retardant and heat-insulating fire-fighting device includes a rigid frame 1 and a flame-retardant and heat-insulating device 2.

[0041] Rigid frame 1 is a rigid frame. The rigid frame can be a metal or non-metal frame structure.

[0042] Flame-retardant heat insulation device 2 is a flame-retardant heat insulation board. The flame-retardant heat insulation board is made of flame-retardant heat insulation materials, such as color-coated steel rock wool board, which consists of iron sheet wrapped around a rock wool core. Lithium batteries can reach temperatures as high as 1200℃ during combustion; rock wool can withstand temperatures up to 1200℃. Rock wool color-coated steel board is currently a mass-produced building material. Iron has a melting point close to 2000℃. Using rock wool color-coated steel board ensures that the heat insulation board remains undamaged and undeformed under the high temperatures of lithium battery combustion. At the same time, the iron sheet has a certain degree of toughness to prevent damage from the impact of a battery explosion.

[0043] A pushing device 5 is provided on the side end of the rigid frame 1. The pushing device 5 can be a pushing rod. The pushing rod can be made of metal or non-metal. The pushing rod is connected to the rigid frame by welding, riveting, bolting, or other methods; the pushing rod can stably withstand external forces and realize convenient movement of the rigid frame.

[0044] The rigid frame 1 includes a support part 11 and a limiting part 12; the limiting part 12 is fixedly provided at the upper end of the support part 11. The lower end of the flame-retardant heat insulation board is located at the upper end of the support part 11, and the upper end of the flame-retardant heat insulation board is matched and located inside the limiting part 12.

[0045] The support part 11 only needs to have the function of supporting the flame-retardant heat insulation board.

[0046] For example, the support part 11 can be a bottom frame plate.

[0047] The limiting part 12 can limit the position of the two sides of the flame-retardant heat insulation board and prevent the flame-retardant heat insulation board from tipping over on the rigid frame 1.

[0048] For example, the limiting part 12 can be a side frame plate, in which case the flame-retardant heat insulation plate is confined inside the side frame plate.

[0049] For example, the limiting part 12 can be a side frame plate with a limiting groove, and the flame-retardant heat insulation plate is matched and set inside the limiting groove.

[0050] In this embodiment, as Figure 1 As shown, the support part 11 adopts a bottom frame plate; in this embodiment, the limiting part 12 adopts a side frame plate; in this embodiment, the flame-retardant heat insulation plate is placed on the upper end of the bottom frame plate, and the two sides of the flame-retardant heat insulation plate are limited by the side frame plate to prevent the flame-retardant heat insulation plate from tipping over.

[0051] A moving device is provided at the bottom end of the rigid frame 1.

[0052] The mobile device only needs to have mobility functionality.

[0053] For example, the moving device can use a wheel fixing plate 3 and a wheel assembly 4; wheel fixing plates 3 are fixed on both sides of the rigid frame 1, and wheel assemblies 4 are provided at the lower end of the wheel fixing plates. At this time, the rigid frame 1 is manually pushed to the designated position by the pushing device 5 to push the wheel assembly.

[0054] For example, the mobile device can employ a wheel fixing plate 3, a wheel assembly 4, a power module, and a control module. Wheel fixing plates are fixed to both sides of the rigid frame 1, and a wheel assembly is located at the lower end of each wheel fixing plate. The power module is connected to the wheel assembly, and the power module is connected to the control module. The power module provides power for the movement of the wheel assembly. The control module controls the power module and has the capability to receive radio or wired signals to control the power output of the power device. In this way, the rigid frame 1 achieves automatic movement to the designated position through the power module and control module, saving time and effort.

[0055] In this embodiment, the mobile device uses wheel fixing plates 3 and wheel assemblies 4; wheel fixing plates 3 are fixed on both sides of the rigid frame 1. One wheel assembly 4 is provided at the lower end of one wheel fixing plate 3, and two wheel assemblies 4 are provided at the lower end of the other wheel fixing plate 3; one wheel assembly 4 is located on the front side of the rigid frame, and the other two wheel assemblies 4 are located on the rear side of the rigid frame. The rigid frame 1 is manually pushed by the pushing device 5 to allow the front side of the rigid frame to quickly insert into the gap between adjacent electric vehicles for effective isolation.

[0056] Wheel 5 can be made of metal or non-metal materials.

[0057] Working principle: When a two-wheeled electric vehicle catches fire, the front side of this rigid frame is quickly inserted into the gap between the adjacent burning electric vehicle and the unburned electric vehicle, which effectively isolates, insulates, and retards the fire. It can not only conveniently and quickly isolate the burning two-wheeled electric bicycle to avoid damage to surrounding items, but also has a light weight, a stable and compact structure, is easy to use, has a low cost, and is easy to install and maintain.

The flame-retardant heat insulation board is made of flame-retardant heat insulation materials, such as color-coated steel rock wool board, which consists of iron sheet wrapped around a rock wool core. Lithium batteries can reach temperatures as high as 1200℃ during combustion; rock wool can withstand temperatures up to 1200℃. Rock wool color-coated steel board is currently a mass-produced building material. Iron has a melting point close to 2000℃. Using rock wool color-coated steel board ensures that the heat insulation board remains undamaged and undeformed under the high temperatures of lithium battery combustion.

[0064] The first support part 13 only needs to have the function of supporting the flame-retardant heat insulation board.

[0065] For example, the first support portion 13 can be a bottom frame plate.

[0066] The first limiting part 14 and the second limiting part 15 only need to limit the positions of the two flame-retardant heat insulation boards on both sides and prevent the two flame-retardant heat insulation boards from tipping over on the rigid frame 1.

[0067] For example, the first limiting part 14 can be a first side frame plate, and the second limiting part 15 can be a second side frame plate. In this case, the upper end of one flame-retardant heat insulation plate is limited inside the first side frame plate, and the upper end of the other flame-retardant heat insulation plate is limited inside the second side frame plate.

[0068] In this embodiment, as Figures 6-9 As shown, the first support part 13 adopts a bottom frame plate; the first limiting part 14 adopts a first side frame plate; and the second limiting part 15 adopts a second side frame plate.
