Description

The present invention relates to a power device that has a housing that houses equipment related to power supply.

In recent years, the number of utility poles has been reduced by burying electric wires such as distribution lines underground. As a result, power equipment that houses equipment related to power supply, such as transformers, switches, and low-voltage branching devices, in a housing is being installed above ground.

For example, Patent Document 1 discloses that by installing additional equipment such as benches, planters, and information display panels on the housing box of an electric power device that is installed on the ground and houses a transformer, switchgear, etc., the electric power device can be made to blend in with its surroundings by being treated as the additional equipment.

On the other hand, when comparing the installation of a seat on the housing box of the power device with the installation of an information display panel (information transmission medium), the seat needs to be low enough that passersby can sit on it by bending their knees, whereas the information display panel needs to be high enough that passersby can see the contents of the information display panel at a glance without bending their back.

Therefore, there are conflicting height requirements when installing a seat and when installing an information display panel, making it difficult to install both a seat and an information display panel in one storage box. However, Patent Document 1 does not take into consideration installing both a seat and an information display panel in one storage box, and is therefore unable to solve this problem.

The present invention was made in consideration of these circumstances, and its purpose is to provide an electric power device that can accommodate both a seat and an information transmission medium in a housing that houses equipment related to power supply.

In the present invention, of the first and second parts, a display that displays information is attached to the top plate of the first part, which is relatively tall, to improve visibility, and a seat is attached to the top plate of the second part, which is relatively short, to improve convenience of use.

In the power device according to the present invention, the equipment includes a transformer, the first section houses a high-voltage section including equipment connected to the high-voltage side of the transformer, and the second section houses a low-voltage section including equipment connected to the low-voltage side of the transformer.

In the present invention, the high-pressure section is housed in the first section and the low-pressure section is housed in the second section, so that the first section and the second section can be made to have different heights from the ground.

The power device according to the present invention has a power supply unit provided on the top plate for supplying power from the low voltage unit to an external device.

In the present invention, the power supply unit is provided on the top plate of the housing, so that power can be supplied from the power device to various external devices that may be installed in the vicinity of the power device.

In the power device according to the present invention, the display attachment portion includes a mounting fixture that protrudes from the top plate of the housing and has a mounting hole for attaching the display.

In the present invention, the mounting fixture is used when mounting the display body on the top plate, making the mounting work of the display body easier.

In the power device according to the present invention, the base mounting portion protrudes from the top plate of the housing and includes a mounting protrusion for mounting the base.

The display body attachment section 13 is a part of the first top plate 4, and the display body attachment section 13 is provided with a mounting fixture 12 for attaching the display body P.

The mounting fixture 12 is, for example, an equal-leg angle iron or an unequal-leg angle iron. The mounting fixture 12 is provided along the edge at the center of both front-rear edges of the first top plate 4. One of the two sides of the mounting fixture 12 is parallel to the top surface of the first top plate 4 and is welded to the top surface of the first top plate 4, for example, and the other side is erected vertically from the first top plate 4. A screw hole 121 (mounting hole) is formed at each of the other two ends.

The second section 20 has a base attachment section 23 for attaching a base B (see FIG. 3) to the second top plate 5. The base attachment section 23 is a part of the second top plate 5, and is provided with an attachment protrusion 22 for attaching the base B.

The mounting protrusions 22 are, for example, stud bolts or stud bolts, and one end of the mounting protrusions 22 is screwed into a screw hole (not shown) formed in the second top plate 5, and protrudes from the upper surface of the second top plate 5. Two mounting protrusions 22 are protruding from the front edge of the second top plate 5, appropriately spaced apart in the left-right direction, and two more mounting protrusions 22 are protruding from each mounting protrusion 22 at the same interval in the front-rear direction.

The high-voltage section 30 is housed inside the first section 10. The low-voltage section 50 is housed inside the second section 20.

Figure 3 is an installation diagram showing the state in which the display body P and base body B are attached to the power device 100. The display body P and base body B are attached to the top plate 6 of the housing 1 installed on the ground. That is, the display body P is attached to the first top plate 4 of the first part 10, and the base body B is attached to the second top plate 5 of the second part 20.

The display body P is an information transmission medium that displays information such as guidance, advertisements, and notifications, and transmits the information to passersby passing near the power device 100. When the display body P is attached to the first top plate 4, for example, it has a roof-shaped plate portion P2 that has an inverted V-shape in vertical cross section, and side wall portions P1 that extend downward from each edge of the roof-shaped plate portion P2. Of the two inclined surfaces of the roof-shaped plate portion P2, the front inclined surface is provided with a display portion P3 on which information to be notified to passersby is displayed.

In the display body P, two mounting through holes P4 corresponding to the screw holes 121 of the mounting fixture 12 are formed in each of the front and rear portions of the side wall portion P1.
When installing, the display body P is positioned so that the front mounting fixture 12 and the rear mounting fixture 12 face the inner surfaces of the front and rear portions of the side wall portion P1, respectively, and with the screw hole 121 of the mounting fixture 12 and the mounting through hole P4 of the display body P aligned, a bolt S is inserted through the mounting through hole P4 and screwed into the screw hole 121.

The seat B has a bench shape with a backrest and two legs B1 made of strip-shaped metal plates bent into a U-shape. As shown in the right diagram of Figure 3, the seat B is attached to the second tabletop 5 toward the front.

When the base body B is attached to the second tabletop 5, the two legs B1 are arranged side by side in the left-right direction. Each leg B1 has a parallel portion that is parallel to the upper surface of the second tabletop 5 and extends in the front-rear direction, and upright portions that rise vertically from both ends of the parallel portion. Each parallel portion has two through holes (not shown) formed therein that correspond to the mounting protrusions 22 of the base body mounting portion 23.
The seat body B is attached to the seat body attachment part 23 by inserting the attachment projection 22 into the through hole of the leg part B1 and screwing a nut onto the other end of the attachment projection 22. Passersby can sit on the seat body B and rest.

The above description has been given with an example in which the seat body B has a backrest and legs B1, but this is not limiting. The seat body B may be configured to have only a seat surface, without having a backrest and legs B1.

As described above, the power device 100 of the first embodiment can attach both the display body P and the seat body B to the housing 1, and has the mounting fixture 12 and mounting protrusions 22, making it easy to attach the display body P and the seat body B. In addition, since the display body P and the seat body B are installed on the housing 1, it is possible to prevent the aesthetic appearance of the sidewalk from being marred by treating them as the display body P and the seat body B, and since the power device 100 serves as a seat and an information transmission medium in addition to its original role, the sidewalk can be used efficiently.

As described above, the power device 100 has the high-voltage section 30, which requires a large storage space due to the large volume of each device involved and the large number of devices, located in the first section 10, and the low-voltage section 50, which does not require a large storage space, located in the second section 20. This makes it possible to provide the first section 10 and the second section 20, which are of different heights, in one housing 1, and satisfies the conflicting height requirements of the seat and the information transmission medium.

In other words, the display body P as an information transmission medium needs to be high enough that passersby can see the contents of the display part P3 at a glance without bending over, and the seat body B as a seat needs to be low enough that passersby can bend their knees and sit on it. Therefore, in the power device 100 of embodiment 1, the display body P is attached to the first part 10, which is tall, to improve the visibility of the display body P, and the seat body B is provided to the second part 20, which is shorter than the first part 10, to improve convenience of use. Therefore, it is possible to combine the roles of a seat and an information transmission medium, which have different height requirements.

Furthermore, in the power device 100 of the first embodiment, the four mounting protrusions 22 are arranged near the front of the second tabletop 5 so that the seat B can be attached near the front of the second tabletop 5. Therefore, the seat B is attached to the front edge of the second tabletop 5, making it easy for passersby to sit on it.

If necessary, the transformer 40 can be partially buried underground to prevent the height of the second section 20 from increasing.

Therefore, use of the power supply unit 60 is not impeded.

The power supply unit 60 is connected to the terminal board 51 of the low voltage unit 50, and receives power supply via the terminal board 51. That is, the terminal board 51 has a plurality of terminals 511 to which low voltage cables are connected, and one end of an electric wire 61 is connected to any one of the terminals 511, and the other end of the electric wire 61 is connected to the power supply unit 60. A through hole (not shown) is formed in the second top plate 5, and the electric wire 61 connects the power supply unit 60 to the terminal 511 of the terminal board 51 through the through hole.

The power unit 100 of the second embodiment has such a configuration and can supply power to various electrical devices that may be installed in the vicinity of the power unit 100. For example, a lighting device L (external device) may be connected to the power supply unit 60 so that the lighting device L illuminates the display unit P3 of the display unit P or the seat body B. Also, a mobile phone base station may be installed on the second tabletop 5 at a position that does not interfere with the seat body mounting portion 23 and the power supply unit 60, and power may be supplied from the power supply unit 60 to the mobile phone base station.

The power supply unit 60 is provided at a position on the second top plate 5 that does not interfere with the base mounting portion 23, so that in addition to the display body P and base body B, the power supply unit 60 can be mounted on one housing 1, allowing the housing 1 to be used effectively.
