MODE FOR CARRYING OUT THE INVENTION

[0009] A specific example of the electric equipment storage rack (hereinafter referred to as "the first rack") of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0010] In the following description, the terms "front", "rear", "left", "right", "upper", and "lower" may be used, but these directions are relative directions set for convenience of explanation. Also, "left" and "right" in each figure are directions in a front view.

[0011] [Overall Configuration] FIG. 1 is a perspective view showing the configuration of the first rack 100 according to an embodiment of the present disclosure. In FIG. 1, in addition to the first rack 100, another electric equipment storage rack (hereinafter referred to as "the second rack") 200 is shown.

[0012] As shown in FIG. 1, the internal space of the first rack 100 has a first space 11 and a second space 12. The first space 11 houses the storage battery 61. The second space 12 houses a server (an example of an electric device) 60A to which power is supplied from the storage battery 61. On the other hand, the second rack 200 does not have a space for housing the storage battery 61, and a server (an example of an electric device) 60B is housed inside.

[0013] Also, in a top view, the second rack 200 is arranged adjacent to one side in the left - right direction of the first rack 100. In the example shown in FIG. 1, the second rack 200 is adjacent to the left side of the first rack 100.

[0014] FIG. 2 is a perspective view showing the configuration of the left side surface of the first rack 100 and the right side surface of the second rack 200 shown in FIG. 1. In FIG. 2, the first rack 100 and the second rack 200 shown in FIG. 1 are shown separately. FIG. 3 is a perspective view showing the state of the first rack 100 shown in FIG. 1 as seen from the front - right side. In FIGS. 1 and 2, a state where the storage battery 61 is placed on all eight shelf portions 21 is illustrated, and in FIG. 3, as will be described later, a state where the storage battery 61 is placed on the six lower shelf portions 21 out of the eight shelf portions 21 is illustrated.

[0015] As shown in FIGS. 2 and 3, the first rack 100 includes a plurality of shelf portions 21 and mounting angles 22 on which the plurality of shelf portions 21 can be installed. Referring to FIG. 3, the mounting angles 22 include a front mounting angle 22A provided in the front inside the first rack 100 and a rear mounting angle 22B provided in the rear inside the first rack 100.

[0016] The front mounting angle 22A and the rear mounting angle 22B are positioned to the right or left of the center in the left-right direction of the first rack 100. In Figures 2 and 3, as an example, the front mounting angle 22A and the rear mounting angle 22B are positioned to the left of the center in the left-right direction. Specifically, the front mounting angle 22A and the rear mounting angle 22B are positioned at a predetermined distance to the left of the center in the left-right direction.

[0017] The shelf section 21 can accommodate one or more storage batteries 61 and extends in the front-rear direction, spanning between the front mounting angle 22A and the rear mounting angle 22B. The shelf section 21 is installed relative to the mounting angle 22 so as to be located on the side of the first rack 100 in the first space 11. In the example shown in Figures 2 and 3, the shelf section 21 is installed to the left of the mounting angle 22. That is, the shelf section 21 is positioned close to the left side of the first rack 100.

[0018] In other words, the left space of the two internal spaces of the first rack 100, which are bounded by a virtual plane along the front-to-back direction demarcated by the front mounting angle 22A and the rear mounting angle 22B, is the first space 11 where the shelf 21 is located. The right space of these two spaces is the second space 12 where the shelf 21 is not located and the server 60A is housed.

[0019] In this way, the server 60A and the battery 61 can be integrated into a single storage rack, thus reducing the space required for the storage rack compared to the case where separate storage racks are provided for the battery 61 and the server 60A.

[0020] Furthermore, as described above, the battery 61 can be mounted to the left of the first rack 100. Therefore, power from the battery 61 of the first rack 100 can be supplied not only to server 60A but also to server 60B housed in the second rack 200, which is adjacent to the left of the first rack 100.

[0021] More specifically, the multiple shelf sections 21 are arranged to be stacked vertically. For example, of the eight shelf sections 21 stacked vertically, each battery 61 placed on the upper four shelf sections 21 (the shelf sections 21 enclosed by the dashed-dotted line X1 in Figure 2) is connected to the server 60A shown in Figure 1. Also, for example, each battery 61 placed on the lower four shelf sections 21 (the shelf sections 21 enclosed by the dashed-dotted line X2 in Figure 2) is connected to the server 60B shown in Figure 1.

[0022] Furthermore, as shown in Figure 3, a fire extinguishing panel 23 is provided between the front mounting angle 22A and the rear mounting angle 22B, separating at least a portion of the boundary between the first space 11 and the second space 12. In the example shown in Figure 3, the fire extinguishing panel 23 is provided in the lower region of the boundary between the first space 11 and the second space 12, where the shelf portion 21 is installed. The fire extinguishing panel 23 has one or more mounting portions 28. A fire extinguishing device, which will be described later, is attached to the mounting portions 28. The detailed configuration of the fire extinguishing panel 23 will be described later.

[0023] Furthermore, as shown in Figure 2, the first rack 100 is further equipped with a side panel 24 provided on the side adjacent to the second rack 200 (the left side in the example shown in Figure 2). By separating the first rack 100 and the second rack 200 with the side panel 24 in this way, security can be enhanced and the seismic resistance of the first rack 100 can be improved.

[0024] The side panel 24 has an opening 25 through which connection lines 31 and 32, such as power supply lines from the battery 61, can be inserted. In the example shown in Figure 2, the opening 25 is formed such that, in a side view, the lower four of the eight stacked shelves 21 are exposed through the opening 25.

[0025] The position and size of the opening 25 are not limited to those shown in Figure 2. For example, the opening 25 may be formed such that all eight shelf sections 21 are exposed through the opening 25 in a side view.

[0026] Furthermore, as shown in Figure 2, the side of the second rack 200 that faces the first rack 100, i.e., the right side of the second rack 200, does not have a side panel. This reduces the number of parts. Alternatively, instead of providing a side panel 24 on the left side of the first rack 100, the side panel 24 could be provided on the right side of the second rack 200.

[0027] [Shelf configuration] (Configuration overview) Figures 4 and 5 are enlarged perspective views showing the configuration of the shelf section 21 shown in Figure 1. As shown in Figures 4 and 5, the shelf section 21 includes a plurality of mounting sections for placing the storage battery 61. More specifically, the shelf section 21 is composed of three plate members: an upper plate 41 and a lower plate 42 which are mounting sections, and a side plate 43 provided between the upper plate 41 and the lower plate 42, and has a roughly U-shaped cross-section.

[0028] The upper plate 41 and the lower plate 42 each extend in the front-rear direction and are attached to the front mounting angle 22A and the rear mounting angle 22B shown in Figure 3. The side plate 43 extends in the vertical direction and is attached so as to span between the front left support column (hereinafter referred to as the "first support column") 26 and the rear left support column (hereinafter referred to as the "second support column") 27 of the first rack 100 shown in Figure 3.

[0029] Thus, by having side plates 43 in addition to the upper plate 41 and lower plate 42 in the shelf section 21, the seismic resistance of the first rack 100 can be improved and the strength of the shelf section 21 can be increased. Furthermore, because there are two mounting plates on which the storage batteries 61 are placed, the number of storage batteries 61 that can be placed on one shelf section 21 can be increased, and the number of parts and the number of steps required to install the shelf section 21 can be reduced.

[0030] As shown in Figures 4 and 5, the top plate 41 has one or more top plate openings 45. The bottom plate 42 has one or more bottom plate openings 46. The side plate 43 has one or more side plate openings 47. In Figures 4 and 5, as an example, four top plate openings 45, four bottom plate openings 46, and three side plate openings 47 are formed.

[0031] Furthermore, each of the upper plate 41 and the lower plate 42 has a bent portion 48 extending downward at the end opposite to the side plate 43 (the right side in the examples shown in Figures 4 and 5). Also, a notch 44 is formed at the rear of the shelf portion 21. In other words, the length in the front-to-back direction of a portion of the upper plate 41 and the lower plate 42 is shorter than the length in the front-to-back direction of the side plate 43.

[0032] (Fitting of the shelf section with the first and second support columns) At the upper end of the side plate 43, a first upper groove 51 is formed near the front end, and a second upper groove 52 is formed near the rear end. At the lower end of the side plate 43, a first lower groove 53 is formed near the front end, and a second lower groove 54 is formed near the rear end.

[0033] Furthermore, a first opening 55 is formed near the front end of the side plate 43, connecting the first upper groove 51 and the first lower groove 53. Also, a second opening 56 is formed near the rear end of the side plate 43, connecting the second upper groove 52 and the second lower groove 54.

[0034] Then, with the shelf section 21 attached to the front mounting angle 22A and rear mounting angle 22B shown in Figure 3, a protrusion (not shown) provided vertically on the first support column 26 of the first rack 100 fits into the first upper groove 51, first opening 55, and first lower groove 53 of the shelf section 21 shown in Figure 4. Also, in this state, a protrusion (not shown) provided vertically on the second support column 27 of the first rack 100 fits into the second upper groove 52, second opening 56, and second lower groove 54 of the shelf section 21 shown in Figure 4.

[0035] The shelf 21 is then fixed to the first support column 26 by attaching fixing members such as screws to the holes 51a formed in the first upper groove 51 and the holes 53a formed in the first lower groove 53. The shelf 21 is also fixed to the second support column 27 by attaching fixing members such as screws to the holes 52a formed in the second upper groove 52 and the holes 54a formed in the second lower groove 54.

[0036] Furthermore, the upper plate 41 and lower plate 42 of the shelf section 21 are fixed to the front mounting angle 22A and the rear mounting angle 22B, for example, by fastening members such as screws. This allows the shelf section 21 to be stably attached to the first rack 100.

[0037] With the fixing members removed, the vertical position of the shelf 21 can be changed by sliding it vertically while it is fitted onto the first support column 26 and the second support column 27.

[0038] (Positional relationship between the shelf and the power outlet bar) Figure 6 is a perspective view of the first rack 100 shown in Figure 1, with multiple shelves 21 provided, as seen from the rear right side of the first rack 100. As shown in Figure 6, for example, a power outlet bar 63 extending in the vertical direction is provided on the rear side of the interior of the first rack 100.

[0039] As described above, since each shelf section 21 has a notch 44 (see Figure 5), when the first rack 100 has multiple shelf sections 21, a space is formed in the vertical direction near these multiple shelf sections 21. Therefore, the outlet bar 63 can be positioned so as to pass through this space. In other words, interference between the shelf sections 21 and the outlet bar 63 can be avoided, and the outlet bar 63 can be positioned near the storage battery 61.

[0040] Note that the notches 44 shown in Figure 5 are not limited to being formed at the rear of the upper plate 41 and lower plate 42, but may also be formed at the front of the upper plate 41 and lower plate 42, or on both the front and rear sides. If the notches 44 are formed on both the front and rear sides of the upper plate 41 and lower plate 42, the shelf section 21 can be used even if its top and bottom are reversed, thereby improving workability.

[0041] [Configuration of the fire extinguishing panel] (Configuration of the mounting section) Figures 7 and 8 are perspective views showing the configuration of the fire extinguishing panel 23 shown in Figure 3. Figure 7 shows the first rack 100 viewed from the front left, and Figure 8 shows the first rack 100 viewed from the front right.

[0042] As shown in Figures 7 and 8, a mounting portion 28 is formed on a part of the fire extinguishing panel 23 by press processing or the like, so as to protrude toward the second space 12. In the example shown in Figures 7 and 8, two mounting portions 28 extending in the vertical direction are formed on the fire extinguishing panel 23.

[0043] Furthermore, each mounting portion 28 has a space into which a fire extinguishing device 33 can be inserted. More specifically, as shown in Figure 8, an opening 29 is formed at the upper end of the mounting portion 28, and the fire extinguishing device 33 is inserted into the internal space of the mounting portion 28 through the opening 29. The length of the mounting portion 28 in the extending direction (vertical direction in the examples shown in Figures 7 and 8) is longer than, for example, the length of the fire extinguishing device 33.

[0044] The fire extinguishing device 33 has a cylindrical shape, for example, covered with a coating. When heat is applied, the coating melts, causing the fire extinguishing agent sealed inside the coating to be ejected. Therefore, if a fire breaks out in the battery 61 in the first space 11, the heat from the battery 61 will cause the fire extinguishing agent to be ejected from the fire extinguishing device 33, thus extinguishing the fire.

[0045] Furthermore, because the fire extinguishing device 33 extends vertically, a single fire extinguishing device 33 can quickly extinguish a fire regardless of which of the multiple stacked batteries 61 in the vertical direction the fire originates from. It is also possible to spray a fire extinguishing agent onto the multiple stacked batteries 61 in the vertical direction.

[0046] Furthermore, the fire extinguishing device 33 may need to be replaced if its expiration date has passed. In such cases, the fire extinguishing device 33 can be removed by pinching it out through the opening 29 of the mounting portion 28, allowing for replacement of only the fire extinguishing device 33 without removing the fire extinguishing panel 23. Additionally, a string or similar device for removal may be provided at the upper end of the fire extinguishing device 33.

[0047] (Positional relationship between the shelf and the fire extinguishing device) Figure 9 is a horizontal cross-sectional view taken along the line IX-IX shown in Figure 8. Figure 10 is a vertical cross-sectional view taken along the line XX shown in Figure 8. As shown in Figure 10, when the fire extinguishing device 33 is inserted into the mounting portion 28, at least a portion of the fire extinguishing device 33 on the side facing the first space 11 is exposed to the first space 11.

[0048] Furthermore, as shown in Figures 9 and 10, when the fire extinguishing device 33 is inserted into the mounting portion 28, it contacts the bent portions 48 of the upper plate 41 and lower plate 42 provided on each shelf portion 21. This prevents the fire extinguishing device 33 from falling off the mounting portion 28 without the need for fixing brackets or the like. In addition, because the fire extinguishing device 33 contacts the bent portions 48 of the shelf portion 21, if a fire breaks out in the storage battery 61 (see Figure 3), heat can be effectively transferred to the fire extinguishing device 33 via the bent portions 48 of the shelf portion 21.

[0049] The cross-section of the mounting portion 28 is not limited to the shape shown in Figure 9, and may be circular or other shapes. Furthermore, the mounting portion 28 may be a separate component from the fire extinguishing panel 23. For example, a fitting having a hat-shaped or L-shaped form may be attached to the fire extinguishing panel 23 as the mounting portion 28 by welding or screwing.

[0050] Figure 11 is a vertical cross-sectional view showing a modified example of the mounting portion 28 shown in Figure 8. For example, as shown in Figure 11, the bottom surface 28a of the mounting portion 28 may be bent at an obtuse angle. In this configuration, the fire extinguishing device 33 receives a force that causes it to tilt toward the shelf portion 21 by contacting the bottom surface 28a. This allows the fire extinguishing device 33 to more reliably come into contact with the bent portion 48 of each shelf portion 21.

[0051] Figure 12 is a vertical cross-sectional view showing a modified example of the bent portion 48 of the shelf section 21 shown in Figure 10. For example, among a plurality of shelf sections 21 stacked vertically (see Figure 7), the bottom plate 42 of the lowest shelf section 21 may have a bent portion 48 that is bent at an obtuse angle, as shown in Figure 12. In this configuration, the fire extinguishing device 33 receives a force that causes it to tilt toward the shelf section 21 by contacting the bent portion 48. Therefore, similar to the configuration shown in Figure 11, the fire extinguishing device 33 and the bent portion 48 of each shelf section 21 can be made to contact more reliably.

[0052] [Differentiation] (Variations in the placement of fire extinguishing panels) Figure 13 is a perspective view showing a modified mounting position of the fire extinguishing device 33. Figure 13 shows the first rack 100 viewed from the rear right side. In the example shown in Figure 7 above, the fire extinguishing device 33 is provided on the right side of the shelf 21 within the first space 11, with the fire extinguishing panel 23 installed thereon. However, the location where the fire extinguishing device 33 is installed is not limited to the right side of the shelf 21, but may be installed in one or more locations within the first space 11, such as the left side, front, and rear of the shelf 21.

[0053] For example, as shown in Figure 13, the fire extinguishing panel 23 may have a configuration that includes a fire extinguishing panel 23A located to the right of the shelf 21 and a fire extinguishing panel 23B located behind the shelf 21. In such a case, for example, mounting portions 28 can be provided on both the fire extinguishing panel 23A and the fire extinguishing panel 23B, and a fire extinguishing device 33 can be attached to each mounting portion 28.

[0054] Furthermore, it is preferable that the bent portion 48 (see Figure 5) of the shelf portion 21 be provided at the end in the direction in which the fire extinguishing device 33 is attached. For example, as shown in Figure 13, when the fire extinguishing device 33 is attached to the right side and rear of the shelf portion 21, it is preferable that the bent portion 48 be provided at both the right end and the rear end of the upper plate 41 and lower plate 42 (see Figure 5) of the shelf portion 21.

[0055] (Variations in the configuration of the fire extinguishing panel) Figure 14 is a perspective view showing a modified configuration of the fire extinguishing panel 23. Figure 14 shows the first rack 100 viewed from the front left. The height of the fire extinguishing panel 23 may be adjustable depending on the number of shelves 21 installed on the first rack 100 and the number of storage batteries 61 housed in the first rack 100. For example, instead of having one fire extinguishing panel 23 as shown in Figure 7, the first rack 100 may have multiple fire extinguishing panels 23C extending in the front-to-back direction, as shown in Figure 14.

[0056] Each fire extinguishing panel 23C has a height corresponding to, for example, the height of an individual shelf 21. Therefore, the number and location of the fire extinguishing panels 23C can be changed according to the number and location of shelves 21 installed in the first rack 100, or the number and location of batteries 61 stored in the first rack 100. In the example shown in Figure 14, batteries 61 are placed on eight shelves 21. In such a case, for example, eight fire extinguishing panels 23C are provided to match the height of eight shelves 21.

[0057] Furthermore, each fire extinguishing panel 23C has, for example, a mounting portion 28 that extends in the front-rear direction, and an opening 30 is formed at the front or rear end (the front end in the example shown in Figure 14) into which the fire extinguishing device 33 can be inserted. Therefore, the fire extinguishing device 33 can be inserted from the opening 30 of the fire extinguishing panel 23C into the internal space of the mounting portion 28. In this way, by providing the fire extinguishing device 33 extending in the front-rear direction in each fire extinguishing panel 23C, if a fire breaks out in the storage battery 61, the fire extinguishing agent of the fire extinguishing device 33 provided in conjunction with the storage battery 61 can be effectively sprayed.

[0058] The first rack 100 is not limited to a configuration with one fire extinguishing panel 23 as shown in Figure 7, or a configuration with multiple fire extinguishing panels 23C extending in the front-to-back direction as shown in Figure 14. For example, it may also be configured with multiple fire extinguishing panels 23 extending in the up-to-down direction.

[0059] (Modified example of the bent section of the shelf) Figures 15 and 16 are vertical cross-sectional views showing modified configurations of the shelf section 21. The bent portion 48 in the upper plate 41 of the shelf section 21 shown in Figure 10 above is bent downward from the end of the upper plate 41. However, the bent portion 48 is not limited to this shape, and may have a shape that bends upward from the end of the upper plate 41, for example, as shown in Figure 15.

[0060] Furthermore, the bent portion 48 may also have an inclined surface 49 that slopes downward at the end opposite to the upper plate 41 (the upper end in the example shown in Figure 15). When the bent portion 48 has such an inclined surface 49, the fire extinguishing device 33 can be easily moved downward while contacting the inclined surface 49 of each shelf portion 21 when it is installed. Note that the bent portion 48 having the same shape as the upper plate 41 shown in Figure 15 may be provided not only on the upper plate 41 but also on the lower plate 42.

[0061] Furthermore, the inclined surface 49 of the bent portion 48 may be provided to slope downward at the end of the upper plate 41, for example, as shown in Figure 16. In this configuration, similar to the configuration shown in Figure 15, the fire extinguishing device 33 can be easily moved downward while contacting the inclined surface 49 of each shelf portion 21 when it is installed. Moreover, not only the upper plate 41, but also the lower plate 42 may be provided with a bent portion 48 having the same shape as the upper plate 41 shown in Figure 16.

[0062] As described above, the first rack 100 according to this embodiment is An electrical equipment storage rack capable of housing a server 60A, A mounting angle 22 is provided inside the first rack 100, It comprises a number of shelf sections 21 on which a battery 61 that supplies power to the server 60A is mounted on a mounting angle 22, Multiple shelf sections 21 are arranged to be stacked vertically. The internal space of the first rack 100 is A shelf section 21 is arranged in a first space 11 capable of housing a storage battery 61, The shelf section 21 is not provided, and there is a second space 12 capable of housing the server 60A, Within the first space 11, a fire extinguishing device 33 containing a fire extinguishing agent is provided at at least one location on the side, front, or rear of the shelf section 21.

[0063] In this case, if the fire extinguishing device 33 is installed on the top plate, and a fire breaks out in a battery 61 placed on one of the lower shelves 21 of the multiple shelves stacked vertically, the fire extinguishing agent from the fire extinguishing device 33 will have difficulty reaching the battery 61. Furthermore, even if heat reaches the fire extinguishing device 33 and the fire extinguishing agent is ejected, it will be obstructed by the battery 61 and shelves 21 placed higher up, making it difficult for the fire extinguishing agent to reach the burning battery 61.

[0064] In contrast, with the above configuration, the fire extinguishing agent from the fire extinguishing device 33 can easily reach any of the multiple shelves 21 stacked vertically, regardless of which battery 61 is placed on. Therefore, fire extinguishing can be carried out quickly.

[0065] Furthermore, the first rack 100 according to this embodiment further includes a fire extinguishing panel 23 provided in at least one location within the first space 11, such as the right side, left side, front, or rear of the shelf section 21. The fire extinguishing panel 23 has a mounting portion 28 to which the fire extinguishing device 33 is attached.

[0066] With this configuration, even fire extinguishing devices 33 that are difficult to stand on their own, such as cylindrical fire extinguishing devices 33, can be stably placed in the first space 11.

[0067] Furthermore, in the first rack 100 according to this embodiment, The mounting portion 28 extends in the vertical direction and has a space into which the fire extinguishing device 33 can be inserted.

[0068] This configuration allows for a more stable placement of the fire extinguishing device 33. Furthermore, since the fire extinguishing device 33 can be attached to the fire extinguishing panel 23 by inserting it into the mounting portion 28, the installation and replacement of the fire extinguishing device 33 can be easily performed.

[0069] Furthermore, in the first rack 100 according to this embodiment, The fire extinguishing device 33 is located on the side of the shelf section 21, at the boundary between the first space 11 and the second space 12.

[0070] With this configuration, the fire extinguishing panel 23 can be used as a partition plate to separate the first space 11 and the second space 12.

[0071] Furthermore, in the first rack 100 according to this embodiment, The shelf section 21 has a mounting section (upper plate 41 and lower plate 42) on which the storage battery 61 is placed. The fire extinguishing device 33 is in contact with the mounting portion of each shelf section 21.

[0072] With this configuration, even if, for example, at least a portion of the fire extinguishing device 33 is exposed to the shelf 21 side so that a fire from the battery 61 can easily reach it, the fire extinguishing device 33 can be prevented from falling off towards the shelf 21 side. In addition, if a fire breaks out from the battery 61, the heat from the fire in the battery 61 can be effectively transferred to the fire extinguishing device 33 via the mounting portion of the shelf 21.

[0073] Furthermore, in the first rack 100 according to this embodiment, The mounting portion of the shelf 21 has a bent portion 48 at the end in the direction in which the fire extinguishing device 33 is installed. The fire extinguishing device 33 is in contact with the bent portion 48 of each shelf section 21.

[0074] This configuration allows for a larger contact surface between the shelf 21 and the fire extinguishing device 33, thereby more reliably preventing the fire extinguishing device 33 from falling off. Furthermore, it allows for more effective transfer of heat generated by a fire originating from the battery 61 to the fire extinguishing device 33.

[0075] Furthermore, in the first rack 100 according to this embodiment, The fire extinguishing device 33 is positioned in the first space 11 by moving downward while contacting the bent portion 48 of each shelf 21. The bent portion 48 has an inclined surface 49 that slopes downward.

[0076] This configuration makes it possible to easily install the fire extinguishing device 33 by moving it downward while bringing it into contact with the inclined surface 49 of each shelf section 21.

[0077] Furthermore, the first rack 100 according to a modified example of this embodiment is further, It comprises multiple fire extinguishing panels 23C having mounting portions 28 extending in the front-to-back or left-to-right direction, A fire extinguishing device 33 is attached to the mounting portion 28 of each fire extinguishing panel 23C. Each of the multiple fire extinguishing panels 23C is installed in a location corresponding to one of the multiple shelf sections 21.

[0078] With this configuration, for example, the number and location of the fire extinguishing panels 23C can be adjusted according to the number and location of the shelves 21 on which the storage batteries 61 are placed.
