Description

[Technical Field]

[0001] The present invention relates to an assembled power receiving panel housing that houses a power distribution board. [Background technology]

[0002] The power distribution board, on which the integrating watt-hour meter and other devices are mounted, is housed in a power receiving panel housing. This power receiving panel housing is made of metal because it must be highly dustproof, weather-resistant, and strong. This metal power receiving panel housing is prone to rust due to wind and rain, and this rust can cause corrosion. If this corrosion progresses, rainwater can seep into the power receiving panel housing, which can cause a short circuit in the wiring. For this reason, if rust or corrosion occurs, it is necessary to replace the power receiving panel housing with a new one. Furthermore, Patent Document 1 discloses a switchboard whose housing can be disassembled when performing maintenance on devices inside the switchboard, and whose housing is strong.

Therefore, gaps 55a and 55b are provided between the bottom surface connecting portions 51c and 51d and the rear surface portion 20. When the power receiving panel housing 100 of this embodiment is assembled, the rear surface connecting portions 21a and 21b fit into the gaps 55a and 55b.

[0055] The bottom surface connecting portions 51a to 51d are provided with a plurality of screw holes 52 (52a to 52h). In this embodiment, for example, two screw holes 52a and 52b are provided in the bottom surface connecting portion 51a of the bottom surface portion 50a, and two screw holes 52c and 52d are provided in the bottom surface connecting portion 51b of the bottom surface portion 50a. Two screw holes 52e and 52f are provided in the bottom surface connecting portion 51c of the bottom surface portion 50b, and two screw holes 52g and 52h are provided in the bottom surface connecting portion 51d of the bottom surface portion 50b. However, the number and arrangement of the screw holes 52a to 52h are not limited to those shown in the figure and can be changed in various ways. Bolts 54a to 54h can be inserted into the screw holes 52a to 52h, respectively.

[0056] Nuts 53a to 53h are welded to the inside of the screw holes 52a to 52h of the bottom surface connecting portions 51a to 51d, respectively, although the nuts 53a to 53h do not necessarily have to be welded.

[0057] 11, when the power receiving panel housing 100 is assembled, the rear connecting portion 21b of the rear portion 20 is disposed in the gap 55b in the bottom connecting portion 51d of the bottom portion 50b. That is, the width of the gap 55b in the Y direction is approximately the length in the Y direction of the rear connecting portion 21b of the rear portion 20. Note that the width of the gap 55b in the Y direction may be equal to or greater than the length in the Y direction of the rear connecting portion 21b of the rear portion 20.

[0058] In the power receiving panel housing 100 of this embodiment, gaps 55a, 55b are formed by removing portions of bottom surface connecting portions 51c, 51d from the bottom surface portion 50b, but this is not limiting. For example, bottom surface connecting portions 51c, 51d may be extended without a gap to the rear surface portion 20, and the ends of rear surface connecting portions 21a, 21b on the bottom surface portion 50b side may be removed to form gaps, so that bottom surface connecting portions 51c, 51d and rear surface connecting portions 21a, 21b do not overlap during assembly. Alternatively, the ends of rear surface connecting portions 21a, 21b on the bottom surface portion 50b side may be cut obliquely, and the ends of bottom surface connecting portions 51c, 51d on the rear surface portion 20 side may be cut obliquely, so that the two do not overlap during assembly.

[0059] In this embodiment, the bottom surface portions 50a, 50b of the power receiving panel housing 100 are divided into two pieces in the Y direction to allow the cables connected to the power distribution board 200 to pass through, but this is not limiting. For example, the bottom surface portion 50 may be divided into three pieces in the X direction, with the cables sandwiched between the two divided portions. Alternatively, the bottom surface portion 50 may be formed from a single piece, with the holes for passing the cables extending to the rear surface portion 20 side and the gap between the cables and the rear surface portion 20 being filled with a filling material (for example, mesh, plastic, wood, etc.).

[0060] [7] Waterproof rubber tape 2, the power receiving panel housing 100 according to this embodiment may have waterproof rubber tapes 80 (80a to 80h), which can prevent rainwater and the like from entering the power receiving panel housing 100.

[0061] For example, the waterproof rubber tapes 80a to 80h may be provided between the side portion 30a and the rear connecting portion 21a, between the side portion 30b and the rear connecting portion 21b, between the front portion 10 and the side connecting portion 31a, between the front portion 10 and the side connecting portion 31b, between the bottom connecting portion 51a and the side portion 30a, between the bottom connecting portion 51b and the side portion 30b, between the bottom connecting portion 51c and the side portion 30a, and between the bottom connecting portion 51d and the side portion 30b.

[0062] The length in the Z direction of the waterproof rubber tapes 80a, 80b is approximately the same as the length in the Z direction of the rear connecting parts 21a, 21b. The length in the Y direction of the waterproof rubber tapes 80a, 80b is shorter than half the length in the protruding direction (Y direction) of the rear connecting parts 21a, 21b. The waterproof rubber tapes 80a, 80b are attached close to the base sides of the rear connecting parts 21a, 21b. When the waterproof rubber tapes 80a, 80b are attached to the rear connecting parts 21a, 21b, the screw holes 22 of the rear connecting parts 21a, 21b are not covered by the waterproof rubber tapes 80a, 80b and are exposed.

[0063] The Z-direction length of the waterproof rubber tapes 80c, 80d is approximately the same as the Z-direction length of the side connectors 31a, 31b. The X-direction length of the waterproof rubber tapes 80c, 80d is shorter than half the length of the side connectors 31a, 31b in the protruding direction (X-direction). The waterproof rubber tapes 80c, 80d are attached close to the base of the side connectors 31a, 31b. When the waterproof rubber tapes 80c, 80d are attached to the side connectors 31a, 31b, the screw holes 32 of the side connectors 31a, 31b are exposed and not covered by the waterproof rubber tapes 80c, 80d.

[0064] The length in the Y direction of the waterproof rubber tapes 80e to 80h is approximately the same as the length in the Y direction of the bottom surface connecting portions 51a to 51d. The length in the Z direction of the waterproof rubber tapes 80e to 80h is shorter than half the length in the protruding direction (Z direction) of the bottom surface connecting portions 51a to 51d. The waterproof rubber tapes 80e to 80h are attached close to the base sides of the bottom surface connecting portions 51a to 51d. When the waterproof rubber tapes 80e to 80h are attached to the bottom surface connecting portions 51a to 51d, the screw holes 52 of the bottom surface connecting portions 51a to 51d are not covered by the waterproof rubber tapes 80e to 80h and are exposed.

[0065] The waterproof rubber tapes 80a to 80h can prevent water and the like from seeping in through the connecting portions described above. However, the material is not limited to rubber tape and can be changed in various ways as long as it is a filler that can fill the gaps in the connecting portions, and may be caulking, for example.

[0066] In the power receiving panel housing 100 according to the present embodiment described above, bolts and nuts are used as detachable fasteners when assembling the front panel 10, rear panel 20, side panel 30a, 30b, top panel 40, and bottom panel 50a, 50b, but this is not limiting. For example, catch clips or the like may also be used as detachable fasteners.

[0067] In addition, in the power receiving panel housing 100 according to this embodiment, the rear surface 20, the side surfaces 30a and 30b, the top panel 40, and the bottom surfaces 50a and 50b are provided with connecting portions 21, 31, 41, and 51, respectively, but the positions at which the connecting portions are provided can be changed in various ways. For example, it is possible to provide the connecting portion on the front surface 10 and eliminate the connecting portions 31 on the side surfaces 30a and 30b.

[0068] Furthermore, in the power receiving panel housing 100 according to this embodiment, the connecting portions 21, 31, 41, 51 are formed integrally with the rear surface 20, the side surfaces 30a, 30b, the top panel 40, and the bottom surfaces 50a, 50b, respectively, but are not limited to this. For example, the rear surface 20, the side surfaces 30a, 30b, the top panel 40, and the bottom surfaces 50a, 50b may be formed without connecting portions like the front surface 10, and separately formed L-shaped mounting brackets may be attached to the corners of each surface with bolts or the like.

[0069] [8] Installation of power receiving panel enclosure 12(a) and 12(b) are schematic diagrams showing the state in which the receiving panel housing according to the embodiment of the present invention is installed on a concrete pole. The state in which the receiving panel housing according to the embodiment of the present invention is installed on a concrete pole will be described below.

[0070] 12(a) and 12(b), the power receiving panel housing 100 of this embodiment is installed on a concrete pole 301. In this case, the power receiving panel housing 100 is attached to, for example, a PM pole metal fitting 302 via bolts or the like in the screw holes 24 (24a to 24h) (see FIG. 4) in the rear surface part 20. Then, the power receiving panel housing 100 is attached to the concrete pole 301 by wrapping this metal fitting 302 around the concrete pole 301.

[0071] [9] How to assemble the power receiving panel case 13(a), 13(b) to 17(a) to 17(c) are diagrams for explaining a method for assembling a power receiving panel housing according to one embodiment of the present invention. The assembling method for a power receiving panel housing according to this embodiment will be described below.

[0073] 13(b), in the fixing portion 70 of the rear surface portion 20, the bolt 73 and the nut 74 are loosened, and the second fixing device 72 is removed from the first fixing device 71. In other words, only the first fixing device 71 is left on the rear surface portion 20.

[0074] Next, as shown in FIG. 14(a), the power distribution board 200 is placed on the first fixture 71 on the lower side of the rear surface portion 20, and the power distribution board 200 is moved toward the rear surface portion 20.

[0075] Next, as shown in Fig. 14(b), the second fixing device 72 is attached to the first fixing device 71 using a bolt 73 and a nut 74. As a result, the power distribution board 200 is sandwiched between the rear surface portion 20 and the fixing portion 70, and the power distribution board 200 is fixed. Note that the power distribution board 200 may be attached after the side surface portions 30a, 30b are attached to both sides of the rear surface portion 20 (Fig. 15(b)).

[0076] 15(a), waterproof rubber tapes 80a and 80b are attached to the rear connecting parts 21a and 21b of the rear part 20. At this time, the waterproof rubber tapes 80a and 80b are attached close to the bases of the rear connecting parts 21a and 21b so as not to cover the screw holes 22a to 22j of the rear connecting parts 21a and 21b.

[0077] Next, as shown in Figure 15(b), side surface portions 30a, 30b are attached to both sides of the rear surface portion 20.

At this stage, it is not necessary to tighten the bolts and nuts into the screw holes 22a and 34b and the screw holes 22f and 34f.

[0078] 16(a), waterproof rubber tapes 80c and 80d are attached to the side surface connecting portions 31a and 31b of the side surface portions 30a and 30b. At this time, the waterproof rubber tapes 80c and 80d are attached close to the bases of the side surface connecting portions 31a and 31b so as not to cover the screw holes 32a to 32j of the side surface connecting portions 31a and 31b.

[0079] 16(b), waterproof rubber tapes 80e-80h are attached to the bottom surface connecting portions 51a-51d of the bottom surface portions 50a, 50b. At this time, the waterproof rubber tapes 80e-80h are attached close to the bases of the bottom surface connecting portions 51a-51d so as not to cover the screw holes 52a-52h of the bottom surface connecting portions 51a-51d. The waterproof rubber tapes 80c and 80d and the waterproof rubber tapes 80e to 80h may be applied in the reverse order.

[0080] Then, the bottom portions 50a, 50b are attached to the side portions 30a, 30b. At this time, the bottom portions 50a, 50b are inserted so that the bottom connecting portions 51a-51d of the bottom portions 50a, 50b are inside the side portions 30a, 30b. Then, bolts 54a, 54b, 54e, 54f and nuts 53a, 53b, 53e, 53f are tightened into the screw holes 35a-35d of the side portion 30a and the screw holes 52a, 52b, 52e, 52f of the bottom connecting portions 51a, 51c. Similarly, bolts 54c, 54d, 54g, 54h and nuts 53c, 53d, 53g, 53h are fastened into the screw holes 35e to 35h of the side surface portion 30b and the screw holes 52c, 52d, 52g, 52h of the bottom surface connecting portions 51b, 51d.

[0081] 17(a), the front surface portion 10 is attached to the side surface portions 30a and 30b. At this time, bolts 12a to 12j and nuts 33a to 33j are tightened into the screw holes 11a to 11j of the front surface portion 10 and the screw holes 32a to 32j of the side surface connecting portions 31a and 31b.

[0082] 17(b), the top panel 40 is attached to the side panel portions 30a and 30b. At this time, bolts 43a to 43d and nuts 44a, 23a, 44b, and 23b are tightened into the screw holes 42a to 42d of the top panel 40, the screw holes 34a, 34b, 34g, and 34h of the side panel connecting portions 31a and 31b, and the screw holes 22a and 22f of the rear panel connecting portions 21a and 21b.

[0083] As a result of the above, the power receiving panel housing 100 having the assembled structure of this embodiment is completed as shown in FIG. 17(c).

[0084]

[10] How to replace the power receiving panel housing 18(a) to 18(c) to 22 are diagrams for explaining a method for replacing a conventional power receiving panel housing with a power receiving panel housing according to one embodiment of the present invention. The method for replacing the power receiving panel housing according to this embodiment will be described below.

[0085] 18(a), a conventional power receiving panel housing 300 is attached to a concrete pillar (not shown). First, the front door 310 of the conventional power receiving panel housing 300 is removed.

[0086] Next, as shown in FIG. 18(b), the protective pipe 202 of the external cable 201 is removed from the power distribution board 200 in the conventional power receiving panel casing 300.

[0087] 18(c), a part (shaded part) of the bottom surface 350 of the conventional power receiving panel casing 300 is cut off. When cutting, it is advisable to protect the power distribution board 200, the external cables 201, etc.

[0088] 19(a), the power distribution board 200 is removed from the conventional power receiving panel housing 300, and the power distribution board 200 is placed on the bottom surface portion 350. Then, a rope 400 or the like is hung on the power distribution board 200, and the power distribution board 200 is suspended by the rope 400.

[0089] Next, as shown in FIG. 19(b), with the power distribution board 200 suspended by the rope 400, the conventional power receiving panel casing 300 is detached from the concrete pillar (not shown) and removed.

[0090] 19(c), the rear part 20 of the power receiving panel housing 100 of this embodiment is installed on a concrete pillar (not shown). At this time, the wiring of the power distribution board 200 is not disconnected from the external wiring, and the power distribution board 200 remains suspended by the rope 400, so there is no power outage.

[0091] Next, as shown in FIG. 20(a), the power distribution board 200 suspended by the rope 400 is placed on the first fixture 71 at the bottom of the rear part 20 of the power receiving panel housing 100 of this embodiment.

[0092] 20(b), the rope 400 suspending the power distribution board 200 is removed, and the power distribution board 200 is fixed to the rear portion 20 using the fixing parts 70. Thereafter, waterproof rubber tapes 80a and 80b are attached to the rear connecting parts 21a and 21b of the rear portion 20. Then, the side portions 30a and 30b are attached to the rear connecting parts 21a and 21b.

[0093] 21(a), holes 56a to 56d for fixing the protective pipe 202 are opened at the boundary between the bottom surface portions 50a and 50b. Thereafter, the bottom surface connecting portions 51a to 51d of the bottom surface portions 50a and 50b are attached to the side surface portions 30a and 30b. At this time, the external cable 201 is passed through the holes 56a to 56d.

[0094] 21(b), the protective pipe 202 is fixed in the holes 56a to 56d of the bottom surface portions 50a and 50b, and the wiring of the power distribution board 200 is arranged. Thereafter, waterproof rubber tapes 80c and 80d are attached to the side surface connecting portions 31a and 31b of the side surface portions 30a and 30b.

[0095] Next, as shown in Fig. 22, the front surface portion 10 is attached to the side surface connecting portions 31a and 31b of the side surface portions 30a and 30b. Thereafter, the top panel connecting portion 41 of the top panel portion 40 is attached so as to cover the front surface portion 10, the back surface portion 20, and the side surface portions 30a and 30b.

[0096] After the receiving panel housing 100 of this embodiment has been installed, if rust occurs in part or all of the receiving panel housing 100 and it becomes necessary to replace the receiving panel housing 100, the work is carried out as follows.

[0097] When part of the power receiving panel housing 100 needs to be replaced, only the corroded part can be removed and replaced. For example, if the top panel 40 is corroded, the bolts 43a to 43d of the top panel 40 can be removed and replaced with a new top panel.

[0098] When the entire power receiving panel housing 100 needs to be replaced, the work basically proceeds in the steps from Figures 18(a) to 18(c) to Figure 22, but there is no need to remove the front door 310 of the conventional power receiving panel housing 300 or to cut off part of the bottom surface 350 (the shaded portion). In other words, because the power receiving panel housing 100 of this embodiment can be disassembled, the dismantling work of the conventional power receiving panel housing 300 can be omitted, and disassembly and replacement can be performed using only bolts, making replacement easy.

[0099]

[11] Effects The power receiving panel housing 100 according to this embodiment is comprised of a front panel 10, a rear panel 20, side panels 30a and 30b, a top panel 40, and bottom panels 50a and 50b. Each of the front panel 10, rear panel 20, side panels 30a and 30b, top panel 40, and bottom panels 50a and 50b has a removable assembly structure. Therefore, if a portion of the power receiving panel housing 100 deteriorates due to rust or other reasons, only the deteriorated part can be replaced. This eliminates the need to replace the entire housing, as with the conventional power receiving panel housing 300, which is integrally formed by welding. This allows for easy part replacement, shortens work time, reduces the number of discarded parts, and reduces disposal costs.

[0100] Furthermore, when replacing a conventional power receiving panel housing 300, the power receiving panel housing 300 cannot be disassembled, so the internal wiring must be disconnected from the external wiring. This conventionally resulted in power outages during the replacement process. In contrast, the power receiving panel housing 100 of this embodiment can be disassembled and reassembled into its front panel 10, rear panel 20, side panels 30a and 30b, top panel 40, and bottom panel 50a and 50b. In other words, the power receiving panel housing 100 can be assembled around the power distribution board 200 suspended by the rope 400 without interfering with the external wiring. Therefore, there is no need to disconnect the wiring of the power distribution board 200 from the external wiring during the replacement process. This allows for a stable supply of electricity during the replacement process, and the power receiving panel housing 300 can be replaced without causing a power outage.

[0101] In particular, in the power receiving panel housing 100 according to this embodiment, the bottom surface portions 50a, 50b are separated into two pieces, and external wiring is passed through the holes 56a to 56d. Therefore, during replacement work, the two bottom surface portions 50a, 50b can be disassembled or assembled while the external wiring remains connected. Furthermore, when assembling the power receiving panel housing 300, the absence of the front surface portion 10 and the top panel portion 40 makes it easy to hang the power distribution board 200 with the rope 400, thereby improving work efficiency.

[0102] Although the embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
