DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage box for electrical equipment.

[0002]

2. Description of the Related Art In general, a storage box for electric equipment installed outdoors has a size such as a size of a bed of a truck for transporting the equipment, a weight limitation of a hanging crane at the time of installation, and a narrow or wide path for carrying in to an installation place. Due to restrictions, it can be divided into multiple parts.

[0003] A housing box of this electric equipment will be described with reference to FIGS. 9 and 10. Reference numerals 31, 32, and 33 denote boxes each having no left and right side plates. The three boxes 31, 32, and 33 are arranged side by side, and necessary electric equipment is disposed inside. 34,
35 and 36 are roof portions of the respective boxes 31, 32 and 33,
To improve the flow of rainwater, each box 31, 32, 33
The back side is inclined.

A convex portion 37 is provided on the roof portion 34 of the box body 31 on the box 32 side, and a convex portion 38 is also provided on the roof portion 35 side of the roof portion 35 of the box body 32 so as to face the convex portion 37. It is provided.

[0005] 39 is a box body 31 between the convex portions 37 and 38.
The cover 32 is provided so as to cover the protrusions 37 and 38 so that rainwater does not enter the inside 32, and is fixed to the protrusions 37 and 38 by bolts 40 and 41.

[0006] Although not shown, convex portions are also provided at opposing portions of the roof portions 35 and 36, and a cover 40 covers the convex portions.

In this conventional example, three boxes are described. However, four boxes are required depending on the size of electric equipment to be housed inside.
The number is increased to five, and the interval is also covered with a cover.

At the left and right ends of the connected boxes 31, 32, 33, walls (not shown) each having a convex portion are provided and covered with covers 42, 43.

[0009]

However, in the above-mentioned conventional construction, the work must be detached from the covers 39, 40, 42, 43 during the work of dividing and connecting with each of the boxes 31, 32, 33. A lot of man-hours were required.

The covers 39, 40, 42, 43
The operator has to climb the roofs 34, 35, 36 of the boxes 31, 32, 33 to perform the removal work, which is a high-altitude operation, which is a very dangerous operation.

Further, many bolts 40 and 41 must be tightened in order to attach the covers 39, 40, 42 and 43, thereby deteriorating the work quality on site.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a housing box for electrical equipment with improved workability.

[0013]

In order to achieve the above-mentioned object, a housing box for electric equipment according to the present invention comprises a plurality of box bodies having at least opposing side surfaces opened, and a box body for housing electric equipment therein. And a roof provided on the upper surface of the box main body in correspondence with each of the box bodies, and a convex portion is provided in a substantially vertical direction on one of the roof portions facing each of the roof portions. Is provided with a cover portion for covering the convex portion.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a convex portion provided on one roof portion and a cover portion provided on the other roof portion are present at opposing portions of adjacent roof portions. By means of the part and the cover part, intrusion of rainwater into the box body can be reduced.

Further, the projection and the cover can be attached at the same time when the roof is attached, so that the number of attachment steps can be reduced.

(Embodiment 1) Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS.

In FIG. 1, FIG. 2, FIG. 3, and FIG.
Numerals 2 and 3 are box-shaped boxes without side walls, and the three boxes 1, 2, and 3 are arranged side by side to create a space in which necessary electric equipment is arranged. .
Reference numerals 4, 5, and 6 denote roof portions of the boxes 1, 2, and 3, which are inclined to the rear sides of the boxes 1, 2, and 3 to improve the flow of rainwater.

Reference numeral 7 denotes a projection provided at the end of the roof 4 of the box 1 on the side of the box 2. Reference numeral 8 denotes a cover section provided at the end of the roof section 5 of the box body 2 on the side of the box body 1 and covering the projection 7 with a concave cross section.

Similarly, a convex portion is provided at the end of the roof 5 of the box 2 on the side of the box 3, and the cover 9 is provided at the end of the roof 6 of the box 3 at the side of the box 2. Covered with.

The height of the convex portion 7 and the cover portion 8 must be set so that the rainwater accumulated on the roof portion 4 and the rainwater that has fallen and scattered on the roof portion 4 do not exceed the height.

A side wall 10 is provided on the side of the box 1 opposite to the box 2, and the top of the side wall 10 is covered with a cover 11 of the roof 4. Furthermore, box 3
A side wall 12 is also provided on the side surface opposite to the box body 2. A cover portion 14 is provided on the top of the side wall 12 so as to cover the convex portion 13 of the roof portion 6.

Next, the operation at the time of installation in the above configuration will be described. First, box 1, 2,
3 are arranged side by side, and necessary electric equipment is installed in the space inside.

Next, the side wall 1 of the box 1 opposite to the side of the box 2
The roof 4 is attached to the box 1 with the cover 11 positioned so as to cover the top. Next, the cover part 8 is positioned so as to cover the convex part 7 of the roof part 4, and the roof part 5 is attached to the box body 2. Next, in the same way,
Is attached to the box 3, and finally, the side wall 12 is attached to the box 3 so that the cover 13 covers the projection 13 of the roof 6.

Similarly to the projection 21 and the cover 22, the roofs 19 and 20 are also provided with a projection and a cover.

The height of the rising portion 23 of the cover portion 22 is set so that the rainwater that has entered from between the roof portions 18 and 19 does not exceed the height of the cover portion 22 when the rainwater flows to the back due to the inclination of the cover 22 to the back. There is a need.

At this time, the lowermost end of the convex portion 21 is located higher than the uppermost end of the rising portion 23 by a distance f.

A side wall 24 is provided on the side of the box 18 opposite to the box 19, and the top of the side wall 24 covers a projection 25 provided at an end of the roof 18. A cover 26 having a concave cross section is provided. Furthermore, box 2
A side wall 27 is also provided on the side opposite to the side of the box 19 of FIG.
A convex portion 28 is also provided at the top of the side wall 27 so as to hang down.
The convex portion 28 is covered by a cover portion 29 provided at an end of the roof portion 20 so as to hang down.

Next, the operation at the time of installation in the above configuration will be described. First, the boxes 15, 16,
17 are arranged side by side, and necessary electrical equipment is installed in the space inside.

Next, the side wall 24 of the box 15 opposite to the box 16 is attached, and the roof 18 is attached to the box 15 so as to cover the cover 26. Next, the roof 19 is attached to the box 16 so as to cover the cover 22 of the roof 18.

As described above, when the roofs 18, 19, 20 and the side walls 24, 27 are attached to the respective boxes 15, 16, 17, the waterproof structure of the roofs 18, 19, 20 is attached at the same time. Can be reduced.

Next, a case where there is rain during use of the storage box will be described. The rainwater falls on the roof parts 18, 19, 20. The roof parts 18, 19, 20
Of the roof 18, 1
It hardly accumulates at 9 and 20, and flows down to the back side. At this time, the roof parts 18, 19, 20 and the side walls 24,
A part of the rainwater that has fallen in the vicinity of the opposing part of the container 27 tends to flow down into the inside of each of the boxes 15, 16, 17 from the gap between the opposing parts, but is blocked by the covers 22, 26, 29. . The rainwater received by the covers 22, 26, 29 flows down to the back of the boxes 15, 16, 17 due to the inclination of the covers 22, 26, 29.

[0038]

As described above, according to the present invention, it is possible to prevent rainwater from entering the inside of a storage box of an electrical facility that would cause a fatal injury with a very simple configuration, and it is possible to reduce the number of assembling steps. It has a great effect.
