[0008] A specific example of the pedestal of the electrical equipment housing box of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0009] In the following description, terms such as "front", "rear", "left", "right", "upper", and "lower" may be used, but these directions are relative directions set for convenience of explanation. In each figure, "F" is "front", "B" is "rear", "L" is "left", "R" is "right", "U" is "upper", and "D" is "lower".

[0010] [Overall Configuration of Electrical Equipment Storage Box] FIG. 1 is a perspective view showing the overall configuration of an electrical equipment storage box 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the electrical equipment storage box 1 includes a box body 11 and a channel base (mount) 12. Inside the box body 11, electrical equipment (not shown) such as a small power receiving facility is accommodated. The small power receiving facility accommodated in the box body 11 is, for example, a step-down transformer panel, and its weight is about 1 t to about 2 t.

[0011] FIG. 2 is a perspective view showing the configuration of the channel base 12 shown in FIG. 1. As shown in FIG. 2, the channel base 12 has four side surfaces 21 and an upper surface 22, and the box body 11 shown in FIG. 1 is placed on the upper surface 22. Further, on each side surface 21, the parts 31 shown in FIG. 1 are detachably attached.

[0012] As shown in FIG. 1, the parts 31 include a wiring part 31A for wiring a duct 13 extending from the electrical equipment accommodated in the box body 11, and a fan part 31B for guiding air into the inside of the box body 11. For example, one or more cables wired from the electrical equipment are inserted through the duct 13.

[0013] [Configuration of Channel Base] (Insertion Hole into which Fork of Forklift is Inserted) Here, when moving the electrical equipment storage box 1 with electrical equipment such as a small power receiving facility accommodated in the box body 11, a forklift is used. Therefore, as shown in FIG. 2, the channel base 12 is formed with an insertion hole 24 into which the fork of the forklift is inserted when moving the electrical equipment storage box 1.

[0014] More specifically, each side surface 21 of the channel base 12 is formed with, for example, two insertion holes (insertion portions) 24 into which two forks of a forklift are respectively inserted. Each insertion hole 24 is, for example, horizontally long and rectangular in shape.

[0015] When the electric equipment housing box 1 is moved, the forks are inserted into the insertion holes 24 so that one of the four side surfaces 21 and the other side surface 21 facing the said side surface 21 are penetrated by the forks. In such a state, when the electric equipment housing box 1 is lifted by a forklift, the electric equipment housing box 1 can be stably moved.

[0016] (Attachment and detachment of wiring parts and fan parts) FIG. 3 is a perspective view showing a state in which the wiring parts 31A and the fan parts 31B are attached to the channel base 12 shown in FIG. 2. FIG. 4 is a perspective view of the state in which the wiring parts 31A and the fan parts 31B are attached to the channel base 12 shown in FIG. 3, as viewed from the front. FIG. 5 is a perspective view of the state in which the wiring parts 31A and the fan parts 31B are attached to the channel base 12 shown in FIG. 3, as viewed from the rear.

[0017] As shown in FIG. 3, after the electric equipment housing box 1 is moved, the insertion holes 24 function as attachment destinations for the parts 31. For example, the fan parts 31B are attached to one of the plurality of insertion holes 24, and the wiring parts 31A are attached to the other insertion holes 24.

[0018] The wiring part 31A is a rectangular plate member, and one or a plurality of wiring holes 32 through which the duct 13 shown in FIG. 1 can be inserted are formed near the center in the left - right direction. As an example, two wiring holes 32 are formed in the wiring part 31A shown in FIGS. 3 to 5. Also, the wiring part 31A is larger than the insertion hole 24 and is attached so as to block the insertion hole 24 from the outside.

[0019] The fan part 31B includes a rectangular plate member 43 larger than the insertion hole 24, and is attached so as to block the insertion hole 24 from the outside with the plate member 43.

[0020] More specifically, fastening part holes 33 (see FIG. 3) into which fastening parts 34 such as bolts (see FIG. 4) can be inserted are formed in each of the wiring part 31A and the plate member 43 of the fan part 31B. Further, as shown in FIG. 5, inside the side surface 21 of the channel base 12, a plurality of fastening part fixing members 35 such as nuts are welded to locations corresponding to the plurality of fastening part holes 33 around the insertion hole 24.

[0021] Therefore, an operator attaching the part 31 to the channel base 12 inserts the fastening part 34 into the fastening part fixing member 35 through the fastening part hole 33 with the part 31 abutted against the channel base 12 so as to cover the insertion hole 24 from the outside of the insertion hole 24. Thereby, the part 31 can be fixed to the channel base 12. Further, the operator can remove the part 31 from the channel base 12 by removing the fastening part 34 from the fastening part fixing member 35.

[0022] In this way, the insertion hole 24 into which the fork of the forklift is inserted is used as an attachment destination of the part 31 after the movement of the electric equipment housing box 1. For this reason, it is not necessary to form dedicated holes for wiring of the duct 13 and attachment of the fan, and the insertion hole 24 can be effectively utilized.

[0023] Further, with the configuration in which each insertion hole 24 is blocked from the outside by the part 31, the attachment work of the part 31 is easy, and foreign matters and the like can be prevented from entering the inside of the electric equipment housing box 1 from the insertion hole 24.

[0024] Note that after the movement of the electric equipment housing box 1, a plate member (not shown) having no hole may be attached to a part of the plurality of insertion holes 24 instead of the wiring part 31A or the fan part 31B.

[0025] In such a case, for example, the number of mounting pieces of the wiring parts 31A is determined according to the number of the ducts 13, and the above-described plate member can be mounted in the insertion holes 24 where the wiring parts 31A or the fan parts 31B cannot be mounted. Thereby, it is possible to avoid a state where there are unused wiring holes 32, and it is possible to prevent foreign matters and the like from entering the inside of the electric equipment housing box 1.

[0026] Further, the channel base 12 is not limited to a configuration in which the fastening member fixing member 35 is welded to the periphery of the insertion hole 24, and may be a configuration in which the fastening member fixing member 35 is not attached.

[0027] Further, each side surface 21 of the channel base 12 is not limited to a configuration in which two insertion holes 24 are formed, and for example, three or more insertion holes 24 may be formed.

[0028] Further, the channel base 12 is not limited to a configuration in which the insertion holes 24 are formed in all of the four side surfaces 21. For example, the insertion holes 24 may be formed only in two opposing side surfaces 21 out of the four side surfaces 21.

[0029] However, when the insertion holes 24 are formed in all of the four side surfaces 21, even if it is impossible to insert the fork due to reasons such as a part of the four side surfaces 21 being in contact with the wall, the fork can be inserted into the insertion holes 24 of the other side surfaces 21.

[0030] Further, when the insertion holes 24 are formed in all of the four side surfaces 21, since the degree of freedom of the mounting positions of the wiring parts 31A shown in FIG. 1 is high, it is easy to adjust the mounting positions of the wiring parts 31A in accordance with the wiring direction of the ducts 13. For this reason, a configuration in which the insertion holes 24 are formed in all of the four side surfaces 21 is preferable.

[0031] (Configuration of Fan Parts) FIG. 6 is a perspective view showing the detailed configuration of the fan part 31B shown in FIG. 3. As shown in FIG. 6, the fan part 31B includes one or more fans 41, a support part 42 that supports the fans 41, and a rectangular plate member 43. The fan part 31B shown in FIG. 6 includes, as an example, two fans 41.

[0032] The support part 42 has two protruding parts 44 that extend downward at both ends in the left - right direction, and the cross - section along the up - down direction is U - shaped. Also, as shown in FIG. 3, at the lower end of each insertion hole 24, two groove parts 25 into which the two protruding parts 44 shown in FIG. 6 are respectively inserted are formed.

[0033] Therefore, when an operator attaches the fan part 31B to the channel base 12, it is necessary to insert the support part 42 and the fan 41 into the inside of the channel base 12 while inserting the two protruding parts 44 into the two groove parts 25 respectively. In this way, since the groove part 25 into which the protruding part 44 is inserted when the fan part 31B is attached in the correct orientation is formed in the insertion hole 24, it is possible to prevent the fan part 31B from being attached to the channel base 12 in a state where the up - down direction is incorrect.

[0034] Note that all the groove parts 25 formed in each insertion hole 24 are blocked by the plate member 43 of the wiring part 31A or the fan part 31B shown in FIG. 3 after the movement of the electrical equipment housing box 1.

[0035] Also, as described above, by removing the fastening part 34 from the fastening part fixing member 35 shown in FIG. 5, the fan part 31B can be removed from the channel base 12. Therefore, maintenance work such as filter replacement of the fan 41 can be easily performed. In particular, small - sized power receiving equipment has a lower heat dissipation efficiency and a higher need for ventilation compared to large - sized electrical equipment. Therefore, the configuration that can easily perform maintenance work and achieve stable ventilation as described above is more effective in the electrical equipment housing box 1 that houses small - sized power receiving equipment.

[0036] As described above, the channel base 12 according to the present embodiment is a channel base on which the box body 11 of the electrical equipment storage box 1 is placed, and has four side surfaces 21. Further, insertion holes 24 into which the forks of a forklift used when moving the electrical equipment storage box 1 are respectively inserted are formed in at least two opposing side surfaces 21 among the four side surfaces 21. After the electrical equipment storage box 1 is moved, the wiring parts 31A can be attached to and detached from the insertion holes 24.

[0037] In this way, the insertion holes 24 into which the forks of the forklift are inserted are formed, and after the electrical equipment storage box 1 is moved, the insertion holes 24 are used as the attachment destinations of the wiring parts 31A, so that the insertion holes 24 can be effectively utilized.

[0038] Further, in the channel base 12 of the electrical equipment storage box 1 according to the present embodiment, a fan part 31B provided with a fan 41 for guiding air into the inside of the box body 11 can be attached to and detached from the insertion holes 24.

[0039] With such a configuration, it is not necessary to secure a dedicated space for attaching the fan part 31B, and the insertion holes 24 can be effectively utilized. Further, since the fan part 31B can be removed from the channel base 12, maintenance such as filter replacement of the fan provided in the fan part 31B can be easily performed.

[0040] Further, in the channel base 12 of the electrical equipment storage box 1 according to the present embodiment, the fan part 31B includes a fan 41 and a support part 42 that supports the fan 41. Further, when the support part 42 and the fan 41 are inserted into the channel base 12 from the insertion holes 24, the fan part 31B is attached to the channel base 12. Further, the support part 42 has a protruding part 44, and a groove part 25 into which the protruding part 44 is inserted when the fan part 31B is attached in the correct orientation is formed in the insertion hole 24.

[0041] With such a configuration, it is possible to prevent the fan part 31B from being attached to the channel base 12 in a state where the vertical direction is incorrect.

[0042] Further, in the channel base 12 of the electric equipment housing box 1 according to the present embodiment, insertion holes 24 are formed in all of the four side surfaces 21.

[0043] With such a configuration, for example, even when it is not possible to insert the fork due to reasons such as a part of the four side surfaces 21 being in contact with the wall, the fork can be inserted into the insertion holes 24 of the other side surfaces 21. In addition, since the degree of freedom in the attachment position of the wiring part 31A is high, it is easy to adjust the attachment position of the wiring part 31A according to the wiring direction of the duct 13 extending from the electric equipment.

[0044] Further, in the channel base 12 of the electric equipment housing box 1 according to the present embodiment, the insertion hole 24 is a rectangular hole. The wiring part 31A is a rectangular plate in which a wiring hole 32 is formed, and is larger than the insertion hole 24. Then, the wiring part 31A is attached to the insertion hole 24 so as to block the insertion hole 24 from the outside.

[0045] With such a configuration, the work of attaching the wiring part 31A to the channel base 12 is easy, and it is possible to prevent foreign matters and the like from entering the inside of the electric equipment housing box 1 from the insertion hole 24.

[0046] [Modification Example] FIG. 7 is a perspective view showing the configuration of a channel base (girder) 112 according to a modification of the embodiment of the present disclosure. FIG. 8 is a perspective view showing a state in which the wiring part 31A and the fan part 31B are attached to the channel base 112 shown in FIG. 7.

[0047] As shown in FIGS. 7 and 8, in the channel base 112 according to the modified example, a notch (insertion part) 124 is formed instead of the insertion hole 24 shown in FIG. 2. In the notch 124, the part 31 shown in FIG. 1 is detachably attached in the same manner as the insertion hole 24 of the channel base 12 shown in FIG. 2. In such a configuration, the notch 124 is wider in the vertical direction compared to the insertion hole 24 of the channel base 12 shown in FIG. 2. Therefore, it is easy to insert the fork of the forklift into the channel base 112.

[0048] On the other hand, in the channel base 12 in which the insertion hole 24 is formed as shown in FIG. 2, higher strength can be ensured compared to the channel base 112 shown in FIG. 7.

[0049] As described above, the embodiments of the present disclosure have been described. Needless to say, the technical scope of the present disclosure should not be construed as being limited by the description of the embodiments. The present embodiment is merely an example, and it is understood by those skilled in the art that various modifications of the embodiments are possible within the scope of the invention described in the claims. The technical scope of the present disclosure should be determined based on the scope of the invention described in the claims and its equivalent scope.
