BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure of an outdoor installation case when an information communication device or the like is installed outdoors, and in particular, for installing a device for generating gas such as a battery therein, This is effective when it is necessary to prevent the ingress of dust and rainwater into the interior without preventing the gas from being exhausted when the housing cannot be completely sealed because it is necessary to exhaust the gas to the outside. The present invention relates to a waterproof structure of an outdoor installation case.

[0002]

2. Description of the Related Art Conventionally, when a battery is mounted in an outdoor installation case as a backup for an internal mounting device at the time of a power failure, as shown in FIG. Side wall surface portion 2
2, the cut-and-raised hole 23 is provided, and the drainage hole 26 is provided at the side wall surface portion 22 where the bottom floor 25 of the battery chamber 27 abuts.

This is because the installed battery 29 generates a large amount of hydrogen gas when the battery 29 is hot or overcharged, and if the concentration exceeds 4%, there is a danger of explosion. It is possible to discharge gas and prevent rainwater from entering.

[0004]

However, according to the conventional waterproof structure for the outdoor installation housing, the hydrogen gas generated from the battery 29 mounted in the outdoor installation housing is
It is possible to discharge the hydrogen gas from the battery chamber 27 to the outside and keep the hydrogen gas concentration below 4% which is the explosion hazardous concentration.
On the other hand, it is not possible to prevent rainwater and dust from entering during wind and rain, which leads to an accident such as a short-circuit of the battery 29, and a structure that prevents rainwater and dust from entering during wind and rain without preventing the discharge of hydrogen gas. Was required.

The present invention has been made in view of the above problems, and its object is to prevent dust and rainwater from entering the inside without preventing the discharge of gas. An object of the present invention is to provide a waterproof structure for an outdoor installation case that can prevent an accident such as a short circuit of mounted equipment.

[0006]

In order to achieve the above object, a waterproof structure for an outdoor installation according to the invention of claim 1 has a hole covered with an eaves-like portion in a side wall portion of a cabinet body. In addition to providing a large number of punching metals, a punching metal is provided inside the side wall surface portion, and a waterproof wall having a large number of holes covered with an eaves-like portion is arranged inside the punching metal.

With such a structure, even if some rainwater enters through the hole covered by the eaves provided on the side wall surface of the cabinet body during wind and rain, it is blocked by the waterproof wall provided inside, The punching metal does not extend to the internal mounting equipment, and the punching metal provided inside the side wall surface prevents fallen leaves, dust, etc. from entering the inside and prevents accidents such as short-circuiting of the internal mounting equipment. . Further, it becomes possible to discharge the gas generated from the internally mounted device to the outside.

In order to achieve the above object, the waterproof structure of the outdoor installation housing according to the invention of claim 2 is the waterproof structure of the outdoor installation housing according to claim 1, wherein the inside of the cabinet body is The battery compartment is separated from the equipment mounting part and the isolation wall, and the bottom floor of the battery compartment is inclined to one side wall surface side, and a drain hole is provided at the side wall surface portion where the bottom floor contacts. It was

With such a construction, not only the same operation as that of the above-mentioned invention of the first aspect can be achieved, but also during wind and rain, a certain amount is provided from the hole covered by the eaves-shaped portion provided on the side wall surface portion of the cabinet body. Even if rainwater enters, this rainwater can be discharged to the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of an outdoor installation housing provided with the waterproof structure of the present invention, and FIG. 2 is a sectional view taken along line XX of FIG.

The outdoor installation according to the present invention comprises a cabinet body 1, which is on the left side.
Right wall surface portion (side wall surface portion) 1A, 1B, upper and lower wall surface portion 1C,
1D and a rear wall surface portion 1E, which is a housing structure having an open front surface. In the front opening 1E of the cabinet body 1, a left door 3 provided with a peep window 5 and a left handle 6A and a right door 4 provided with a right handle 6B are provided so as to be able to open in a double-door manner. That is, the left door 3
Has its left edge 3a attached to the left edge 1a of the front opening 1E via a hinge (not shown).
Has its left edge 4a attached to the right edge (not shown) of the front opening 1E via a hinge (not shown).

The left wall surface 1A of the cabinet body 1 is provided with a plurality of cut and raised holes A formed by forming a plurality of cut and raised holes 12 in a row in the vertical direction at predetermined intervals. These cut-and-raised holes 12 are covered with an eaves-shaped portion 12A made of a cut-and-raised piece and have a rainwater intrusion-preventing hole structure (holes covered with the eaves-shaped portion). Further, the punching metal 13 is fixed to the inner surface of the left wall surface portion 1A of the cabinet body 1, and the hole portion 13A of the punching metal 13 is cut and raised to overlap the hole 12. Therefore, the large number of cut-and-raised holes 12 provided in the left wall surface portion 1A of the cabinet body 1 serve to prevent rainwater from entering the inside, and the inner punching metal 13 is free from dust and leaves. It has a role to prevent from getting inside.

Further, the inside of the cabinet main body 1 is formed into a battery chamber 7 which is separated by a device mounting portion 17 and an isolation wall 17A, and a bottom floor 15 of the battery chamber 7 is formed.

Is covered with an eaves-shaped cut-and-raised piece 14A and has a rainwater intrusion-preventing hole structure, which prevents infiltration of rainwater during wind and rain.

Next, in the outdoor installation case constructed as described above, hydrogen gas is generated from the battery 9, and particularly when the battery 9 is in a high temperature state or an overcharged state, the amount of hydrogen gas generated increases, There is a danger of reaching an explosive concentration of 4%. Since the waterproof wall 14 is provided with cut-and-raised holes 14-1, hydrogen gas generated from the battery 9 passes through the cut-and-raised holes 14-1 and through the hole 13A of the punching metal 13, Further, since the hydrogen gas is discharged to the outside through the cut-and-raised hole 12 provided in the left wall surface portion 1A of the cabinet body 1, it is possible to keep the hydrogen gas concentration in the battery chamber 7 below the explosion dangerous concentration.

According to the above-mentioned embodiment, even if a certain amount of rainwater enters through the cut-and-raised hole 12 provided in the left wall surface portion 1A of the cabinet body 1 in the case of wind and rain, the waterproof wall provided therein is provided. The punching metal 13 is blocked by 14 and does not extend to the internal mounting equipment. The punching metal 13 provided inside the left wall surface portion 1A prevents fallen leaves, dust and the like from entering the inside, and prevents the internal mounting equipment from being short-circuited. Accidents can be prevented. Further, it becomes possible to discharge the gas generated from the internally mounted device to the outside.

The bottom floor 15 of the battery compartment 7 is
By inclining to the left wall surface portion 1A side and providing the drainage hole 16 in the portion of the left wall surface portion 1A with which the bottom floor 15 abuts,
During rainy weather, even if some rainwater enters through the cut-and-raised hole 12 provided in the left wall surface portion 1A of the cabinet body 1, this rainwater can be discharged to the outside.
