[0031] In some embodiments, fire extinguishing agent 31 uses water, adds certain amount of flame retardant in water;Or fire extinguishing agent is sand, directly covers on lithium ion battery, or fire extinguishing agent 31 uses chemical material, not limited here.

[0032] In some embodiments, fire extinguishing bag 3 can be installed at the top of storage cavity 2, or fire extinguishing bag 3 is installed on the side wall of storage cavity 2, and the flame of lithium ion battery can burn fire extinguishing bag 3 when burning, and the burned fire extinguishing agent 31 can flow from fire extinguishing bag 3 to lithium ion battery and extinguish the flame.

[0033] Fire extinguishing bag 3 is installed at the top of storage cavity 2, and fire extinguishing agent 31 directly falls on lithium ion battery;Fire extinguishing bag 3 is installed on the side wall of storage cavity 2, and fire extinguishing agent 31 flows to lithium ion battery from one side.

[0034] In some embodiments, fire extinguishing bag 3 is made of low-temperature combustible material.

[0035] In some embodiments, storage cavity 2 is arranged in cabinet 1 in the form of a checkered pattern.The cabinet 1 is welded or spliced by steel plates, and the steel plate material can avoid damage to the wall of the cabinet 1 when the lithium ion battery explodes and burns, and can block the spread of fire to other storage cavities 2.

[0036] In some embodiments, the storage cavities 2 are arranged in multiple layers in the cabinet 1, and each layer has multiple storage cavities 2, which can be designed according to the space of the factory building.

[0037] In some embodiments, the cabinet body 1 can be assembled by multiple storage cavities 2, which is convenient for assembly and transportation, and the number of storage cavities 2 can be limited according to the actual space of the factory building. The height and length of the cabinet body 1 can be limited to meet the installation in the position and reduce the waste of space.

[0038] In some embodiments, when storing lithium ion batteries, the lithium ion batteries are placed in the storage cavity 2 in depth, or only one lithium ion battery is placed in each storage cavity 2, so as to prevent the lithium ion batteries from being stacked in multiple layers and avoid the flame or explosion from damaging the fire extinguishing bag 3 when the bottom layer of lithium ion batteries burns.

[0039] In some embodiments, a fixing grid for fixing the lithium ion battery is arranged on the inner bottom wall of the storage cavity 2, the lithium ion battery is inserted into the fixing grid, and the lithium ion battery is fixed. The inner diameter of the fixing grid is equal to or greater than the outer diameter of the lithium ion battery. Alternatively, a flexible pad is arranged on the inner wall of the fixing grid to prevent the lithium ion battery from being scratched when inserted.

[0040] In some embodiments, the depth of the storage cavity 2 can be deeper, but the height of the storage cavity 2 is limited, because the lithium ion batteries can be placed in only one layer in the storage cavity 2, and the spacing between the lithium ion batteries and the fire extinguishing bag 3 is limited to ensure that the flame can burn the fire extinguishing bag 3 when the lithium ion battery burns.

[0041] The opening end of the cabinet body 1 is provided with a cabinet door 4 for sealing the cabinet body 1.

[0042] In some embodiments, the cabinet door 4 is installed at the opening end of the cabinet body 1, and the cabinet door 4 seals the storage cavity 2, so that the storage cavity 2 stores the lithium ion battery alone and does not communicate with other storage cavities 2, thereby avoiding the flame from causing serial combustion of the lithium ion batteries in other storage cavities 2 when the lithium ion battery self-ignites.

[0043] In some embodiments, when the cabinet door 4 is closed, the wall of the cabinet door 4 can contact the opening end of the cabinet body 1 and the outer wall of the opening end of the storage cavity 2.

[0044] A storage box 5 for placing the lithium ion battery is fixedly installed, slidably installed, movably installed or detachably installed in the storage cavity 2.

[0045] In some embodiments, the storage box 5 is installed on the inner bottom wall of the storage cavity 2, and the opening of the storage box 5 faces upward. When the lithium ion battery burns, the flame goes upward to avoid spreading to the surrounding, and at the same time, the extinguishing agent 31 directly falls into the storage box 5 after the fire extinguishing bag 3 is broken, and directly covers the lithium ion battery, thereby avoiding the loss of the extinguishing agent.

[0046] In some embodiments, the extinguishing agent 31 is water, with flame-retardant materials added to the water, and the water flows into the storage box 5 to submerge the lithium-ion battery.

[0047] In some embodiments, the extinguishing agent 31 is sand, which flows into the storage box 5 and then covers and buries the lithium-ion battery to isolate it from the air.

[0048] In some embodiments, the shape of the storage box 5 is smaller than that of the storage cavity 2, or the length and width of the outer wall of the storage box 5 are equal to the length and width of the inner wall of the storage cavity 2.

[0049] In some embodiments, the height of the storage box 5 is less than or equal to half the height of the storage cavity 2, a fire extinguishing bag 3 is installed at the top of the storage cavity 2, and there is a certain gap between the fire extinguishing bag 3 and the top of the storage box 5. This gap is used to put the lithium-ion battery into the storage box 5.

[0050] like Figures 1 to 2 As shown, a support mechanism for fixing the fire extinguishing bag 3 inside the storage cavity 2 is installed.

[0051] In some embodiments, the support mechanism may support the bottom of the fire extinguishing bag 3, or fix the side of the fire extinguishing bag 3, or suspend the top of the fire extinguishing bag 3, etc.

[0052] The support mechanism includes a detachable or integrally molded fastener 6 installed on the inner wall of the storage cavity 2 and a grid plate 7 installed on the fastener 6, with the fire extinguishing bag 3 placed on the grid plate 7.

[0053] In some embodiments, two fasteners 6 are provided, and the two fasteners 6 are respectively installed on the inner walls on both sides of the storage cavity 2. A gap is provided between the grid plates 7 so that the flame can directly burn the fire extinguishing bag 3 and the fire extinguishing agent 31 can flow into the storage box 5 along the gap between the grid plates 7.

[0054] like Figure 3 As shown, the fireproof layer 11 is coated with fireproof paint on the walls surrounding the storage cavity 2; or the fireproof layer 11 is glued or integrally molded with fireproof material and installed on the walls surrounding the storage cavity 2.

[0055] In some embodiments, when a large fire occurs, the flames on the fireproof layer 11 can escape into other storage cavities 2 through gaps created by prolonged use.

[0056] The opening end of the cabinet door 4 or cabinet body 1 is fitted with a seal and mates with the opening end wall of multiple storage cavities 2.

[0057] In some embodiments, after the cabinet door 4 is closed, a sealing element seals the storage cavity 2. The shape and size of the sealing element are the same as the shape and size of the opening of the storage cavity 2, so that the individual storage cavities 2 are not connected.

[0058] The bottom of the cabinet body 1 is provided with sliding wheels.

[0059] In some embodiments, the sliding wheels facilitate the movement of the cabinet body 1, and the sliding wheels are provided with brakes, which are opened when the cabinet body 1 is not moved, so as to avoid the cabinet body 1 from being moved by accidental impact.

[0060] As shown in Figure 3 The wall around the storage cavity 2 is also provided with a heat insulation layer 32 for insulating heat propagation, which is attached or integrally formed.

[0061] In some embodiments, the heat insulation layer 32 prevents heat transfer when the lithium ion battery is on fire, so as to cause the lithium ion battery in other storage cavities 2 to be subjected to high temperature and cause self-ignition.

[0062] First, the fireproof layer 11 prevents the spread of fire, and then insulates high temperature, so as to prevent the high temperature from being transferred to the wall of the cabinet body 1 and then to the lithium ion battery in other storage cavities 2.

[0063] The lithium ion battery partition type explosion-proof storage cabinet will be further described below in combination with the use process.

[0064] When the lithium ion battery partition type explosion-proof storage cabinet is used: the lithium ion battery is stored in the storage box 5, and the cabinet door 4 is closed. When the lithium ion battery is on fire, the fire burns the fire extinguishing bag 3, or the lithium ion battery explodes and is cut by the fragments of the lithium ion battery, or the explosion shock wave breaks the fire extinguishing bag 3, and then the fire extinguishing agent 31 in the fire extinguishing bag 3 flows to the burning lithium ion battery to extinguish the fire.

[0065] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application patent; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
