[0015] An embodiment of the invention is described below. As can be understood from Fig. 1 to Fig. 4, in this embodiment, in an installation structure for an electric equipment storage box 1 into which an electric wire 41 is drawn from a utility pole 4, and an electric device 2 electrically connected to the electric equipment storage box 1, the electric equipment storage box 1 is supported by the utility pole 4 so as not to tip over, and the electric device 2 is also supported by the utility pole 4 so as not to tip over. Therefore, it is easy to prevent the electric equipment storage box 1 and the electric device 2 from tipping over.

[0016] The positional relationship between the electrical equipment storage box 1 and the electrical equipment 2 is preferably such that, in a plan view, the angle formed by the line connecting the center of gravity of the electrical equipment storage box 1 to the center of the utility pole 4 and the line connecting the center of gravity of the electrical equipment 2 to the center of the utility pole 4 is greater than 0 degrees and less than 360 degrees. In this way, the direction of the force supporting the electrical equipment storage box 1 and the direction of the force supporting the electrical equipment 2 are different, so that the magnitude of the force acting to tilt the utility pole 4 can be suppressed.

[0017] The installation structure on the utility pole 4 in the embodiment is for supporting the electric equipment storage box 1 and the electric equipment 2 on the utility pole 4, and includes a mounting base 5 for attaching to the utility pole 4, the electric equipment storage box 1, and the electric equipment 2. The mounting base 5 is not essential, but if the mounting base 5 on which the electric equipment storage box 1 is placed is configured to be fixed to the utility pole 4, the electric equipment storage box 1 can be supported from below regardless of the height at which the electric equipment storage box 1 is installed. Note that it is preferable that the mounting base 5 on which the electric equipment storage box 1 is placed and the mounting base 5 on which the electric equipment 2 is placed are fixed so as to sandwich the electric pole 4 between them.

[0018] The electrical equipment storage box 1 is a distribution board, switchboard, high-voltage power receiving equipment, etc., which draws in an electric wire 41 from a utility pole 4 and supplies power to a load. When the electrical equipment storage box 1 is a distribution board, switchboard, etc., the electric wire 41 is drawn from a pole-mounted transformer installed on the utility pole 4 into the electrical equipment storage box 1, and the wire is taken out from the electrical equipment storage box 1 to supply power to the load.

[0019] Furthermore, if the electrical device 2 is a generator, electricity generated by the generator can be drawn into the electrical equipment storage box 1, such as a distribution board or switchboard, and supplied to a load connected to an electric wire 41 extending from the electrical equipment storage box 1. If the electrical equipment storage box 1 is a high-voltage power receiving facility, a high-voltage cable can be drawn from the distribution line 41 on the utility pole 4, transformed, and then drawn out from the electrical equipment storage box 1 to supply power to a load.

[0020] The electric equipment storage box 1 is electrically connected to the electric equipment 2, and the electric equipment 2 is electrically connected to the electric equipment storage box 1 by supplying power from the electric equipment storage box 1 or by supplying power to the electric equipment storage box 1. Examples of the electric equipment 2 include a vehicle charging device, an air conditioner, a storage battery, a generator, and other items that are generally installed outdoors.

[0021] For example, if the electrical device 2 is a vehicle charging device, an air conditioner, or a storage battery, it is electrically connected as a load to the electrical device storage box 1, and therefore power is supplied from the electrical device storage box 1. Also, if it is a generator that generates power using renewable energy such as a solar power generation device or a wind power generation device, it is electrically connected as a power source for the electrical device storage box 1, and therefore can supply power to a load that is separately connected to the electrical device storage box 1.

[0022] The mounting base 5 fixed to the utility pole 4 is for placing the electric equipment storage box 1 and the electric equipment 2 on it. It is preferable to fix the electric equipment storage box 1 and the electric equipment 2 placed on the mounting base 5 to the utility pole 4 with a mounting bracket so that they do not fall over. The mounting bracket may have any structure, but for example, the mounting bracket may be formed by a mounting band 32 that surrounds the entire circumference of the utility pole 4 and a bracket main body 31 that is fixed to the electric equipment storage box 1 and the electric equipment 2.

[0023] When using a mounting bracket, for example, the bracket body 31 is fixed to the back or side of the electrical equipment storage box 1 or the electrical device 2 by screws or welding, and then the electrical equipment storage box 1 or the electrical device 2 is placed on the mounting base 5, and the mounting band 32 is passed through the bracket body 31 and then surrounded by the utility pole 4, and tightened to fix the electrical equipment storage box 1 or the electrical device 2 to the utility pole 4 via the mounting bracket.

[0024] It is preferable that the method of installing the electrical equipment storage box 1 and the electrical device 2 on the utility pole 4 comprises the steps of fixing the mounting base 5 to the utility pole 4 so as to sandwich the utility pole 4, placing the electrical equipment storage box 1, which pulls in the electric wires 41 from the utility pole 4, and the electrical device 2, which is electrically connected to the electrical equipment storage box 1, on the mounting base 5, and supporting the electrical equipment storage box 1 and the electrical device 2 on the utility pole to prevent them from falling over.

[0025] Here, a description will be given of some specific examples of the arrangement of the electric device storage box 1 and the electric device 2. In this description, the electric device 2 is assumed to be a vehicle charging device.

[0026] In the example shown in Fig. 1, a utility pole 4 is positioned between an electric equipment storage box 1 and an electric device 2. More specifically, the electric equipment storage box 1 and the electric device 2, which is a vehicle charging device, are installed in positions facing each other with the electric pole 4 at the center. In this example, a mounting base 5 is provided separately for each of the electric equipment storage box 1 and the electric device 2. The mounting base 5 in the embodiment has a cutout portion 51 that allows a portion of the electric pole 4 to be positioned inside. This cutout portion 51 allows a portion of the electric pole 4 to be positioned inside when the mounting base 5 is fixed to the electric pole 4.

[0027] The mounting base 5 preferably has an opening 52 through which the electric wires 41 can pass. If such an opening 52 is provided, the opening 52 can be used when inserting the electric wires 41 from the bottom surface of the electric equipment storage box 1 or the electric device 2 placed on the mounting base 5 toward the inside, making the wiring work easier.

[0028] 5, an opening 52 is formed in the end face of the mounting base 5 opposite the utility pole 4 side so as to be recessed toward the utility pole 4 side, making the mounting base 5 substantially U-shaped. Note that the mounting base 5 does not have to be limited to this shape, and as can be seen from FIG. 6, the mounting base 5 may not be provided with an opening 52 through which the electric wire 41 can pass.

[0029] The mounting base 5 of the embodiment has connection surfaces 53 on the left and right of the cutout portion 51 that can come into contact with other mounting bases 5. If the mounting bases 5 are connected to each other by bringing the connection surfaces 53 of adjacent mounting bases 5 into contact with each other, it becomes easier to prevent the mounting bases 5 from shifting in the horizontal direction.

[0030] 4 and 5, two mounting bases 5 having the same shape in a plan view are fixed to the utility pole 4, and the connection surfaces 53 located on the left and right of the cutout 51 are in contact with each other, so that the angle formed by the connection surfaces 53 located on the left and right of the cutout 51 is 180 degrees. An electrical equipment storage box 1 is placed on one mounting base 5, and an electrical device 2 is placed on the other mounting base 5. The two mounting bases 5 are configured to cover the entire circumference of the utility pole 4.

[0031] When fixing such a mounting base 5 to a utility pole 4, first, the mounting bases 5 are moved from both sides of the existing utility pole 4 in the radial direction of the utility pole 4, and the utility pole 4 is sandwiched between the mounting bases 5 so that parts of the utility pole 4 fit into the notches 51 of both mounting bases 5. Then, with the connection surfaces 53 of these mounting bases 5 connected, the mounting bases 5 are fixed to the utility pole 4.

[0032] The structure for fixing the mounting base 5 to the utility pole 4 is not particularly limited, but the mounting bases 5 may be fixed to each other to be fixed to the utility pole 4, or each mounting base 5 may be fixed to the utility pole 4 using a mounting bracket such as a mounting band. When fixing multiple mounting bases 5 to the utility pole 4, the multiple mounting bases 5 may be fixed together.

[0033] 2, the mounting base 5 can be exemplified by fixing the mounting base 5 to the utility pole 4 at a position slightly higher than the ground surface. In this way, the space below the mounting base 5 can be used as a wiring space for the electric equipment storage box 1 and the electric device 2. When used in this way, it is preferable to provide the mounting base 5 with an opening 52 through which the wiring can be inserted.

[0034] 7, the mounting base 5 may be provided so as to contact the ground surface. By installing the mounting base 5 on the ground surface, it becomes unnecessary to consider the load applied to the mounting base 5 from the electrical equipment storage box 1 or the electrical equipment 2, and therefore the structure for fixing the mounting base 5 to the utility pole 4 can be simplified. In this case, it is preferable to provide an opening 52 in the mounting base 5 and use the height of the mounting base 5 between the ground surface and the electrical equipment storage box 1 or the electrical equipment 2 as a storage space for the electric wires 41 continuing to the electrical equipment storage box 1 or the electrical equipment 2.

[0035] 8, the height of the mounting base 5 on which the electric device storage box 1 is placed and the height of the mounting base 5 on which the electric device 2 is placed may be different. Of the electric device storage box 1 and the electric device 2, the heavier one may be placed at a lower position, and if the electric device 2 is an electric device that requires operation such as a vehicle charging device, the electric device 2 may be placed at a lower position. To make this possible, it is preferable to arrange the electric device storage box 1 so that the height of the bottom surface of the box 1 is different from the height of the bottom surface of the electric device 2.

[0036] In the embodiment, each mounting base 5 is fixed using a mounting bracket such as a mounting band 32. In the example shown in Fig. 8, a leg 54 is provided at the end of the mounting base 5 opposite the utility pole 4, but this is not essential. However, if the mounting base 5 is provided with the leg 54, the weight of the electrical equipment storage box 1 and the electrical device 2 can be distributed to the leg 54 side even if the mounting base 5 is fixed to the utility pole 4 at a position slightly higher than the ground surface, and therefore the fixing structure of the mounting base 5 to the utility pole 4 can be simplified.

[0037] Incidentally, in the example shown in Fig. 1 etc., the electrical equipment storage box 1 and the electrical equipment 2 are installed with their back faces facing the utility pole 4, but taking into consideration the size and layout of the installation location, the electrical equipment storage box 1 and the electrical equipment 2 may be arranged with their sides facing the utility pole 4 (see Fig. 9). By orienting the electrical equipment storage box 1 and the electrical equipment 2 in the same direction, work on the electrical equipment storage box 1 and the electrical equipment 2 can be performed more efficiently, for example during maintenance.

[0038] In the examples so far, two mounting bases 5 are fixed to one utility pole 4, but the number of mounting bases 5 attached to one utility pole 4 does not have to be limited to two. As can be seen from Figs. 10 to 12, three mounting bases 5 may be fixed to the utility pole 4. The example shown in Fig. 10 shows a structure in which three electrical equipment storage boxes 1 and three electrical devices 2 are installed on three mounting bases 5 attached so that their extending directions are different in a plan view. The height of the mounting bases 5 may be in contact with the ground surface as in the above-mentioned examples, or may be different.

[0039] In this example as well, the mounting base 5 has a cutout portion 51 and an opening 52. In the example shown in Figures 8 to 10, the angle between the connection surfaces 53 located on both the left and right sides of the cutout portion 51 is set to 120 degrees so that the utility pole 4 is surrounded by three mounting bases 5 having approximately the same shape in a plan view.

[0040] However, when using the mounting base 5 of this type, it is not necessary to use three mounting bases 5 as a set. For example, as can be seen from Figs. 13 and 14, only two mounting bases 5 may be used so that the angle between the directions in which the mounting bases 5 extend is 120 degrees. By installing the mounting bases 5 so that they form an angle of 120 degrees, the electrical equipment storage box 1 and the electrical equipment 2 can be moved to one side, so that the electrical equipment storage box 1 and the electrical equipment 2 can be installed even on a utility pole 4 installed close to a wall. Of course, the two mounting bases 5 may be fixed to the utility pole 4 at a distance from each other.

[0041] As can be seen from Figures 15 to 17, four mounting bases 5 may be fixed to one utility pole 4. The example shown in Figure 15 shows a structure in which four electrical equipment storage boxes 1 and four electrical devices 2 are installed on four mounting bases 5 that are attached so that their extending directions are different in a plan view. The height of the mounting bases 5 may be in contact with the ground surface as in the example described above, or may be different.

[0042] In this example as well, the mounting base 5 has a cutout portion 51 and an opening 52. In this example, the angle between the connection surfaces 53 located on both the left and right sides of the cutout portion 51 is 90 degrees so that the utility pole 4 is surrounded by four mounting bases 5 having approximately the same shape in a plan view.

[0043] Even in the case of mounting bases 5 of this type, it is not necessary to use four of them as a set. For example, as can be seen from Figs. 18 and 19, only two mounting bases 5 may be used so that the angle between the directions in which the mounting bases 5 extend is 90 degrees. By installing the mounting bases 5 at a 90-degree angle, the electrical equipment storage box 1 and the electrical equipment 2 can be moved to one side, so that the electrical equipment storage box 1 and the electrical equipment 2 can be installed even on a utility pole 4 installed close to a wall. Of course, the two mounting bases 5 may be fixed to the utility pole 4 at a distance from each other.

[0044] In the above example, the angles formed by the connection surfaces 53 located on both the left and right sides of the notch 51 of the mounting base 5 are 180 degrees, 120 degrees, and 90 degrees, but the angles are not limited to these and can be any angle. For example, the angle formed by the connection surfaces 53 located on both the left and right sides of the notch 51 of the mounting base 5 may be 72 degrees, with five mounting bases 5 covering the entire circumference of the utility pole 4, or may be 60 degrees, with six mounting bases 5 covering the entire circumference of the utility pole 4. In addition, it is not necessary to assume that multiple mounting bases 5 of the same shape will cover the entire circumference of the utility pole 4, and the angle may be 150 degrees, for example.

[0045] In the examples described so far, a plurality of mounting bases 5 having approximately the same shape in plan view are fixed to a single utility pole 4 for the electrical equipment storage box 1 and the electrical equipment 2, but it is not necessary to be limited to such an example, and for example, mounting bases 5 of different sizes or mounting bases 5 having different angles between the left and right connection surfaces 53 of the cutout portion 51 may be used. In this case, it is preferable to determine the size and shape of the mounting base 5 in accordance with the size of the electrical equipment storage box 1 and the electrical equipment 2 to be placed.

[0046] In the above examples, a plurality of mounting bases 5 are provided to mount the electric device storage box 1 and the electric device 2 on separate mounting bases 5, but a plurality of electric device storage boxes 1 and electric devices 2 may be mounted on one mounting base 5. For example, in the example shown in FIG. 20, the mounting bases 5 of the example shown in FIG. 17 are connected to each other. In this case, the electric pole 4 is sandwiched between two mounting bases 5 of the same shape in a plan view, but the electric pole 4 may be covered by combining one mounting base 5 of the example shown in FIG. 17 connected to three mounting bases 5. Of course, the present invention is not limited to such an example, and various shapes of mounting bases 5 may be used.

[0047] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be embodied in various forms. [Explanation of symbols]
