DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will now be described with reference to the accompanying drawings, in which the same or corresponding components are designated by the same reference numerals.

[0011] (First embodiment) Fig. 1 is a perspective view showing a fire extinguishing system including a battery mounting shelf according to a first embodiment of the present disclosure, Fig. 2 is a perspective view showing a battery unit.

[0012] As shown in FIG. 2, the battery unit 10 has a cell stack 12, a tray 14, a cover 16, and an extinguishing agent holding member 18. The cell stack 12 has a plurality of power storage cells arranged in one direction. The tray 14 supports the cell stack 12. The cover 16 houses the cell stack 12 together with the tray 14. The tray 14 and the cover 16 are made of, for example, metal. The extinguishing agent holding member 18 is a member capable of holding an extinguishing agent 20 (see FIG. 1). An example of the extinguishing agent holding member 18 is gypsum board. The battery unit 10 may be made of only the cell stack 12, or may be made of a single power storage cell.

[0013] As shown in FIG. 1, the fire extinguisher 1 includes a battery mounting shelf 100 and a fire extinguishing agent supply section 200.

[0014] The extinguishant supply unit 200 supplies or sprays an extinguishant 20 such as water. Examples of the extinguishant supply unit 200 include a sprinkler and a device that supplies an extinguishant by gravity or pump pressure by opening a valve. The extinguishant supply unit 200 is disposed above the battery mounting shelf 100. The extinguishant supply unit 200 supplies the extinguishant 20 downward.

[0015] The battery mounting shelf 100 is a shelf capable of mounting a plurality of battery units 10. The battery mounting shelf 100 has a plurality of support parts 110, a plurality of lateral guide plates 120, a plurality of vertical plates 130, and a fire extinguishing agent holding member 140. Each of the support parts 110, each of the lateral guide plates 120, and each of the vertical plates 130 is made of, for example, metal.

[0016] The multiple support parts 110 are arranged so as to be spaced apart in the vertical direction. Each support part 110 supports a battery unit 10. In the example shown in Fig. 1, the multiple support parts 110 are arranged so as to be three aligned in the horizontal direction and four in the vertical direction. In this embodiment, each support part 110 is formed in a flat plate shape. Each support part 110 is supported by four pillars.

[0017] Each of the support portions 110 has a mounting portion 112 and an opening h. In addition, in Fig. 1, the mounting portion 112 is indicated by a dashed line.

[0018] The placement portion 112 is a portion on which the battery unit 10 can be placed. The placement portion 112 is formed flat.

[0019] The opening h is a portion through which the extinguishing agent 20 flows. The opening h is configured as a through hole. The opening h is formed on the side of the mounting portion 112. Specifically, the opening h is formed on both sides of the mounting portion 112 in the lateral direction (horizontal direction). The opening h has a shape that extends long in the depth direction (direction perpendicular to both the vertical direction and the lateral direction).

[0020] Each lateral guide plate 120 guides the flow of the extinguishing agent 20 in a lateral direction. The "lateral direction" includes not only the horizontal direction but also a direction intersecting the horizontal within a range in which the extinguishing agent 20 can be guided. Each lateral guide plate 120 is disposed below each support portion 110. The lateral guide plate 120 has an edge portion 124a that causes the extinguishing agent 20, which has flowed down through the opening h in the support portion 110 located above the lateral guide plate 120, to flow down toward the placement portion 112 in the support portion 110 located below the lateral guide plate 120. The edge portion 124a is located vertically above the placement portion 112.

[0021] As shown in FIG. 1, the lateral guide plate 120 has a lateral guide plate body 122 and a moving plate 124.

[0022] The lateral guide plate body 122 is located below the opening h, and receives the extinguishing agent 20 that has flowed down through the opening h. The lateral guide plate body 122 is formed in a flat plate shape.

[0023] The moving plate 124 is movable laterally relative to the lateral guide plate body 122. For example, a guide pin may be fixed to the lateral guide plate body 122, and the moving plate 124 may have an insertion hole through which the guide pin is inserted and which extends laterally. The moving plate 124 includes an edge portion 124a.

[0024] Each vertical plate 130 partitions a pair of openings h adjacent to each other in the horizontal direction. Each vertical plate 130 is formed in a flat plate shape. Each vertical plate 130 supports a horizontal guide plate body 122.

[0025] The extinguishant holding member 140 is capable of holding the extinguishant 20. An example of the extinguishant holding member 140 is a gypsum board. The extinguishant holding member 140 may be provided on the lower surface of the support portion 110 or on the lower surface of the lateral guide plate 120. The extinguishant holding member 140 may also be provided on the surface of the vertical plate 130.

[0026] As described above, in the fire extinguisher 1 of this embodiment, when the extinguishing agent 20 is supplied from above the battery mounting shelf 100, the extinguishing agent 20 flows down through the opening h of the support part 110, is received by the lateral guide plate 120 and guided in the lateral direction, and flows down from the edge part 124a of the lateral guide plate 120 toward the mounting part 112 below, as shown by the arrow in Fig. 1. Therefore, a shortage of the supply of the extinguishing agent 20 downstream in the supply direction (downward, etc.) of the extinguishing agent 20 is suppressed.

[0027] Second embodiment Next, a battery mounting shelf 100 according to a second embodiment of the present disclosure will be described with reference to Fig. 3. Note that in the second embodiment, only the parts different from the first embodiment will be described, and the description of the same structure, action, and effect as the first embodiment will not be repeated.

[0028] In this embodiment, each support portion 110 is made up of four support pieces that support the corners of the bottom surface of the battery unit 10, and an opening h is defined between each pair of support pieces in the depth direction.

[0029] Moreover, the vertical plate 130 is formed in a mesh shape.

[0030] Third embodiment Next, a battery mounting shelf 100 according to a third embodiment of the present disclosure will be described with reference to Fig. 4. Note that in the third embodiment, only the parts different from the first embodiment will be described, and the description of the same structure, action, and effect as the first embodiment will not be repeated.

[0031] In this embodiment, the vertical plate 130 is omitted, and each lateral guide plate 120 is supported by a rear support plate 150. The rear support plate 150 stands upright from one end of the support portion 110 in the depth direction. The rear support plate 150 is formed in a flat plate shape. The lateral guide plate 120 is connected to an upper end of the rear support plate 150. The lateral guide plate 120 and the rear support plate 150 may be formed, for example, by bending a single metal plate.
