The battery mounting rack 100 includes a plurality of support portions 110, a plurality of lateral guide plates 120, a plurality of vertical plates 130, and a fire extinguisher holding member 140. Each support portion 110, each lateral guide plate 120, and each vertical plate 130 is made of metal, for example.

[0020] The plurality of support portions 110 are arranged in a manner spaced apart from each other in the vertical direction. Each support portion 110 supports the battery cell 10. Figure 1 In the example shown, the plurality of support parts 110 are arranged in three layers in the horizontal direction and in four layers in the vertical direction. In the present embodiment, each support part 110 is formed in a flat plate shape. Each support part 110 is supported by four pillars.

[0021] Each support portion 110 has a placement portion 112 and an opening h. Figure 1 In FIG. 1 , the placement portion 112 is indicated by a single-dot chain line.

[0022] The placement portion 112 is a portion on which the battery cell 10 can be placed. The placement portion 112 is formed flat.

[0023] The opening h is a portion for the fire extinguishing agent 20 to flow down. The opening h is composed of a through hole. The opening h is formed on the side of the loading portion 112. Specifically, the opening h is formed on both sides of the loading portion 112 in the lateral direction (horizontal direction). The opening h has a shape extending long in the depth direction (a direction orthogonal to both the up-down direction and the lateral direction).

[0024] Each lateral guide plate 120 guides the flow of the fire extinguishing agent 20 in the lateral direction. In addition, the "lateral direction" includes not only the horizontal direction but also the direction intersecting the horizontal direction within the range that the fire extinguishing agent 20 can be guided. Each lateral guide plate 120 is arranged below each support portion 110. The lateral guide plate 120 has an edge portion 124a, and the edge portion 124a allows the fire extinguishing agent 20 that flows down through the opening h of the support portion 110 located above the lateral guide plate 120 to flow down toward the placement portion 112 of the support portion 110 located below the lateral guide plate 120. The edge portion 124a is located vertically above the placement portion 112.

[0025] like Figure 1 As shown, the transverse guide plate 120 has a transverse guide plate body 122 and a moving plate 124 .

[0026] The lateral guide plate body 122 is located below the opening h, and receives the fire extinguishing agent 20 flowing down through the opening h. The lateral guide plate body 122 is formed in a flat plate shape.

[0027] The movable plate 124 can move relative to the lateral guide plate body 122 in the lateral direction. For example, a guide pin may be fixed to the lateral guide plate body 122, and an insertion hole may be provided in the movable plate 124. The insertion hole allows the guide pin to pass through and extends in the lateral direction. The movable plate 124 includes an edge portion 124a.

[0028] Each vertical plate 130 partitions a pair of openings h adjacent to each other in the lateral direction. Each vertical plate 130 is formed in a flat plate shape. Each vertical plate 130 supports the lateral guide plate body 122 .

[0029] The fire extinguisher holding member 140 can hold the fire extinguisher 20. A gypsum board or the like can be cited as the fire extinguisher holding member 140. The fire extinguisher holding member 140 can be provided on the lower surface of the support portion 110 or on the lower surface of the horizontal guide plate 120. In addition, the fire extinguisher holding member 140 can be provided on the surface of the vertical plate 130.

[0030] As described above, in the fire extinguishing device 1 of the present embodiment, when the fire extinguishing agent 20 is supplied from above the battery mounting rack 100, Figure 1 As shown by the middle arrow, after the fire extinguishing agent 20 flows down through the opening h of the support portion 110, it is received by the lateral guide plate 120 and guided in the lateral direction, and flows down from the edge portion 124a of the lateral guide plate 120 toward the lower placement portion 112. Thus, insufficient supply of the fire extinguishing agent 20 to the downstream side of the supply direction (downward, etc.) of the fire extinguishing agent 20 is suppressed.
