Description

[Detailed Description of the Invention] This invention relates to an assembly type package type outdoor power distribution board having a passage inside thereof, and particularly to the structure of a large door provided on the side wall thereof.

Generally, this type of outdoor switchboard requires a large door for carrying in when an indoor switchboard is installed inside. The door is curved on all four sides to provide insulation and increase rigidity, and has an inner panel on the inside.

FIG. 1 is an external perspective view showing the structure of the package type outdoor power distribution board of this invention. In this diagram,
1 shows a package type outdoor power distribution board, which is composed of a base assembly 2, a side wall assembly 3, and a roof assembly 4. 5
is the door for loading.

In addition, apart from the door 5 for carrying in, a person can perform maintenance and maintenance.
An entrance/exit door (not shown) for entering and exiting for inspection is provided on a part of the side wall, and the two doors are connected via the internal passage (not shown) inside the package type outdoor switchboard 1. There is.

First, the conventional structure of the door 5 will be explained with reference to FIG. Figure 2 is a partial sectional view corresponding to the cross section taken along line X-X in Figure 1, where 4A is the rising part of the roof board;
B is the roof truss. Door 5 has outer panel 5A
and an inner panel 6. Reference numeral 7 denotes a heat insulating material installed inside the door 5 and the outer wall of the outdoor switchboard 1.
8 is a gasket disposed around the door 5, and 9 is a flange for attaching the gasket 8. Reference numeral 10 denotes an eaves provided over almost the entire width of the door 5.

In the conventional example configured as described above, the effects of the eaves 10 and the seal 8 can normally prevent rainwater from entering, but in bad weather with strong winds, the upper ends of the roof truss 4B and the door 5 Rainwater accumulates and enters the interior through the contact portion of the packing 8 due to wind pressure. This is particularly likely to occur with the wide door 5. In addition, machining is required to attach the eaves 10, and the protruding eaves 10 often cause problems during transportation.

This invention has been made for the purpose of eliminating the above-mentioned drawbacks of the conventional technology.

In order to achieve the above object, this invention has a horizontal bent part at the upper end of the outer panel of the door provided separately from the entrance/exit door on the side wall of the outdoor switchboard, and the upper ends of the left and right ends of the door are partially cut out. A U-groove beam is disposed over the entire width of the door between the inside of the horizontal bent portion and the cutout portion of the left and right end bag bent portions, and forms an edge frame of the side wall opening. From the full width of the upper flange on the roof truss side to the horizontal bending part and U
A deflector plate is provided that extends outward in the middle of the groove beam and guides rainwater entering the U-groove beam from the gap between the vertical column and the upper end of the door, and at least the inside of the U-groove beam of the door and the left and right bag bending portions. It has a structure with a packing on the inside. An embodiment of this invention will be described below.

Figures 3 to 5 show an embodiment of this invention, and Figure 3 is a cross-sectional view taken along the line X-X of Figure 1;
Figure 4 is a perspective view of the main parts of the door, and Figure 5 is the Y-
It is a sectional view taken along the Y line. In these figures,
4A, 4B, 5, 5A, 6, 7, and 8 are respectively the same as those shown in FIG. is formed. A notch is partially provided above the left and right bag bent portions 5C. A U-groove beam 11 having a substantially U-shaped cross section is disposed in the partially cutout portion, that is, on the lower inner side of the horizontal bent portion 5B, and its both ends are joined to the left and right end bent portions 5C. In addition, the U groove beam 11
The upper end of the door 5 has a lower height on the side opposite to the outer panel 5A, and is configured to have a predetermined distance L from the horizontal bent portion 5C. 12 is the U-groove beam 11
This is an auxiliary plate welded to the lower side of the panel, and is used to fix the inner panel 6 with screws 13.

A heat material 7 is installed inside the outer panel 5A and the inner panel 6. The packing 8 is attached all around the door inside the U-groove beam 11 and the bag bent portion 5C. 14 is an upper flange. 15 is a deflection plate with a Z-shaped cross section, the upward vertical side 15A is welded to the upper flange 14, and the horizontal side 15B is connected to the horizontal bent portion 5.
B and the U-groove beam 11 extend outwardly, and the downward vertical side 15C is disposed above the U-groove beam 11. 16 is a screw that fixes the roof truss 4B to the upper flange 14. Reference numeral 17 denotes a vertical column constituting the edge frame of the side wall opening. The width of the deflection plate 15 is made equal to the inner dimension between the vertical columns 17, 17. The vertical column 17 is made of square pipe steel, and is connected to both side wall panels 3A with bolts 22 using anchor nuts 21 caulked to the sides of the vertical column. 18 is a vertical flange welded to the vertical column 17. Numeral 19 is a bolt member for fixing the door 5 to each flange 14, 18 on the inside.
20 is a hinge. 23 is a sealing member installed between the vertical column 17 and the side wall panel 3A. Reference numeral 24 indicates the end of the horizontal bent portion 5B formed at the upper end of the outer panel 5A of the door 5 and the upper flange 1.
This is a second gasket provided between the deflection plate 15 attached to the deflection plate 4 and the deflection plate 15, if necessary.

The door 5 for carrying in is constructed so that a person can enter the outdoor switchboard 1 through an entrance/exit door (not shown) formed separately from the door 5 and remove the bolts 19 from the inside passage side, similar to the conventional example described above. If you do this, you can open the switchboard outward using the hinge 20,
This door 5 is opened to carry in or take out large objects such as indoor switchboards.

In addition, since the height of the indoor switchboard carried into the outdoor switchboard 1 is large, it is desirable that the height of the side wall opening is as large as possible. However, there are restrictions due to the configuration of the falling portion 4A of the roof board. Therefore, in such a case, for example, the falling portion 4A and the roof truss 4B may be
Either the vertical dimension of the upper flange 14 is made as short as possible, or the upper flange 14 is
and attach it to the roof truss 4B using screws 16.
The upper flange 14 and the deflection plate 15 can be removed inwardly when the indoor switchboard is carried in, and the height of the side wall opening can be increased.

Since it is not the purpose of this invention to increase the height of the side wall opening in this way, either of the above two methods may be used depending on the relative relationship with the height dimension of the indoor switchboard to be brought in. Or both.
Further, other measures may be taken as necessary, and it is clear that this invention does not necessarily require the above-mentioned configuration to enlarge the side wall opening.

The upper flange 14 and the vertical flange 18 are the third
As shown in the diagram, each can be divided so that the bottom and top ends are in close contact with each other. Further, if necessary, a removable silicone sealant or the like may be applied to the seam to improve waterproofness. Further, when opening the door 5, it is necessary to remove the bolt 19, but this is done infrequently and does not pose a problem. Rather, it serves to increase the strength of the side wall by tightening the bolts. Furthermore, the lower end of the door can have a structure in which a gasket is disposed between the lower flange and the inner surface of the door, as in the conventional case.

According to the above configuration, the horizontal bent portion 5B formed at the upper end of the vertical column 17 and the outer panel 5A forming the edge frame of the side wall opening.
Rainwater entering through the gap reaches the upper side of the deflection plate 15 and is guided into the U-groove beam 11 along the downward vertical side 15C. The U-groove beam 11 plays the role of a gutter and drains rainwater to both left and right ends. Further, by arranging the second gasket 24 on the upward vertical side 15A of the deflection plate 15, it is possible to reduce the amount of rainwater that enters the U-groove beam 11, and to prevent rainwater from entering the interior through the contact surface of the gasket 8 even in strong winds. can be prevented.

Since the eaves 10 (Fig. 2) are not required,
No processing is required for the falling portion 4A of the roof board. This is advantageous in terms of manufacturing because the same roof configuration can be achieved regardless of whether the door 5 is included or not. Also,
Since there is no eaves 10, there will be no hindrance during transportation.

In the conventional one, the packing 8 is provided on the flange 9 side, so removing the upper flange 14 or the lower flange (not shown) would result in the packing 8 being separated, but according to this invention, the packing Since 8 is provided on the door side, the upper flange 14 and the lower flange can be relatively easily removed.

According to this invention, it is possible to create a structure that does not allow rainwater to enter the interior even in strong winds, so it can be applied to a package-type outdoor power distribution board with internal insulation and a wide door. A certain effect was obtained.
