【Example】

(First Embodiment) A first embodiment of the present invention will be described with reference to the drawings. 1 is a cross-sectional plan view of the storage case, FIG. 2 is a side cross-sectional view taken along the line AA of FIG. 1, FIG. 3 is a front view taken along the line BB of FIG. 1, and FIG. In the case main body, a monitor device and the like are installed inside the case main body 1.
That is, a camera body 30 and its lens 31 are provided at the center of the case body 1, and an optical fiber lamp 33 serving as an illumination light source is provided on both sides of the camera body 30. Is extended outside through a flexible hose 36. The optical fiber lamp 33 guides light having passed through the optical fiber cable 34 to a lamp of an illumination unit so as to be illuminated. Reference numeral 37 denotes a temperature detector provided inside the case main body 1. When the temperature inside the case main body 1 detected by the temperature detector 37 exceeds a predetermined upper limit value, a control device (not shown) is used. Alarm.

The case main body 1 is formed of a closed body made of a material such as a steel plate. The closed bodies 1a to 1d are formed in a rectangular parallelepiped cylindrical shape by welding or the like in order to minimize a seal portion (joining portion between the closed bodies). And a rear closure 1f
In order to make the inspection of the monitor device possible, the cylindrical closures (front surface, back surface, both side surfaces) 1a to 1d and screws 3 are fixed to be detachable. On the other hand, the front closure 1e has a structure that can be opened and closed as described later. It should be noted that each joint 2 is not provided with a seal member,
A blow pipe 7 for introducing a gas such as air or nitrogen is laid inside the case body 1. In addition, cylindrical closures 1a to 1
In d, cooling chambers 13a and 13b are formed by covering the outside with a covering 12, and the cooling chambers 13a and 13b are formed.
Purge pipe 1 for introducing fluid such as air or water into 3b
1 is connected, and a discharge port 16 for discharging the fluid to the outside is provided. The cooling chambers may be formed independently of each other or may be communicated with each other. In this example, a partition plate 14 is provided to divide the cooling chamber into two parts, a front side and a rear side, of the case body 1. A purge pipe 11 and a discharge port 16 are provided for each of the partitioned front cooling chamber 13a and rear cooling chamber 13b. The cooling chambers need not be provided for all the closures, and may be formed, for example, only for the closures 1a.

A front closure (opening / closing lid) 1 e facing the lens 31 of the camera body 30 can be opened and closed via an air cylinder 20. That is, the opening / closing lid 1e is connected to the piston 21 of the air cylinder 20 via the rotation shaft 22, and the piston 21 is connected to the air cylinder 20 via air pressure.
Is extended, the opening / closing lid 1e is connected to the hinge 2
3 and is opened (FIG. 4). On the other hand, when the piston 21 is shortened and returned to the air cylinder 20 via the air pressure, the opening / closing lid 1e is rotated around the hinge 23 and closed. Reference numeral 24 denotes a detector such as a proximity switch provided to face the open / close lid 1e, and detects the open / close state of the open / close lid 1e via the detector 24.

In the tubular closures 1a and 1b, a curtain passage 5 is formed near the opening / closing lid 1e from the right end to the center and from the left end to the center in the front view of FIG. A number of outlets 6 communicating with the curtain passage 5 are provided at appropriate intervals. The curtain passage 5 is connected to a curtain pipe 4 for supplying a gas such as air or nitrogen. The outlets 6 may be directed in the vertical direction, but in this example, the outlets 6 are arranged so as to be slightly inclined outward of the case body 1.

Next, the operation of the storage case having the above structure will be described. First, when the monitor device is not operated, the opening / closing lid 1e is closed via the air cylinder 20. Then, air is supplied from the blow pipe 7 and the front cooling chamber 13a is supplied from the purge pipe 11 respectively.
When air is supplied to the rear cooling chamber 13b, the air from the blow pipe 7 is guided to the inside of the case main body 1, and the inside of the case body 1 is maintained at a higher pressure than the installation environment pressure (for example, atmospheric pressure). A part of the air in the case body 1 leaks to the outside at a low pressure from the gap between the joints 2 of the closing body. For this reason, the case body 1 can be sealed without interposing a sealing member in the joint 2. On the other hand, the purge pipe 1
The air guided from 1 flows through the front-side cooling chamber 13a and the rear-side cooling chamber 13b, and is discharged from each of the discharge ports 16, so that the inside of the case body 1 can be insulated and cooled.

On the other hand, when operating the monitor device, the opening / closing lid 1e is opened via the air cylinder 20. Then, similarly to the above, when air is supplied from the blow pipe 7 and the purge pipe 11 and air is supplied from the curtain pipe 4, the air is guided into the case body 1 as described above, thereby joining the joints. 2, the air blown out of the case body 1 is released and released to the outside to be replaced to cool the inside of the case body, and the air flowing into the cooling chambers 13a and 13b is also used. The inside of case body 1 is cooled. Air from the curtain pipe 4 is closed by the upper and lower closing bodies 1a, 1a, respectively.
The air curtain is blown out from a number of air outlets 6 through a curtain passage 5 formed in b. For this reason, even if the opening / closing lid 1 e is in the open state, it is shut off by the air curtain, so that it is possible to prevent moisture, dust, mist and the like from entering the case body 1. In addition, since the optical fiber lamp 33 is used as a light source for illumination of the monitor device, even if the storage case is installed in a vibrating environment, there is no breakage of the ball as compared with the case of using a white burnt ball, and a failure occurs. Few. When a liquid such as water is used as a fluid to be supplied to each of the cooling chambers 13 and 13b, a tube or the like may be connected to the discharge port 16 to collect the liquid.
A baffle plate can also be provided to allow the fluid to flow evenly in each of a and 13b.

(Second Embodiment) FIG. 5 is a side sectional view showing another storage case, which has substantially the same structure as that of the first embodiment, and only different points will be described. In FIG. 5, members corresponding to those in FIG. 2 are denoted by the same reference numerals, and in this embodiment, the case body 1 is cooled and the closures 1 a to 1 d, 1 e,
The purpose is to enable sealing without interposing a seal member at the joint 2 of 1f. That is, a purge pipe 11 for introducing a gas such as air or nitrogen is connected to the front-side cooling chamber 13a and the rear-side cooling chamber 13b formed in the cylindrical closures 1a to 1d, respectively.
Reference numerals 13b communicate with the purge grooves 15 through the communication holes 40, respectively. The purge groove 15 extends over substantially the entire length of the joint 2 of the closing body, for example, as shown in a partial perspective view of the inside of FIG. It is provided over. A purge groove 15 is also provided in the joint 2 between each of the surfaces 1a to 1d of the tubular closure and the front closure (open / close lid) 1e.

Since the storage case of this embodiment has the above-described configuration, first, when the monitor device is not operated,
The opening / closing lid 1e is closed via the air cylinder 20. When air is supplied from the purging pipe 11, the air from the purging pipe 11 flows through the front cooling chamber 13a and the rear cooling chamber 13b, respectively, and the purge groove 1
5 while applying air pressure to the joint 2 of the closed body via the purge groove 15, leaks from the gap of the joint 2 and is discharged to the outside. Therefore, the inside of the case body 1 can be cooled by the air flowing through the front cooling chamber 13a and the rear cooling chamber 13b, and the air is blown out from the joint 2 through the purge groove 15, so that the joint 2 is The case main body 1 can be sealed without interposing a sealing member, and it is possible to prevent environmental moisture, dust, mist, and the like from entering the case main body 1 from the joint 2.

On the other hand, when operating the monitor device, the opening / closing lid 1e is opened via the air cylinder 20. Then, air is supplied from the blow pipe 7 and the curtain pipe 4, and the supply from the purge pipe 11 is stopped. Then, cooling and sealing of the inside of the case body 1 can be performed by the air guided from the blow pipe 7, and the air from the curtain pipe 4 forms an air curtain, so that the inside of the case body 1 is formed. To prevent moisture, dust, mist, etc. from leaking into The reason why the supply from the purge pipe 11 is stopped when the opening / closing lid 1e is opened is to prevent a large amount of air from being released from the purge groove 15 at the open position. It is effective to introduce air from the purge pipe 11 only to the space 13b to cool the case body 1 and to seal the joint 2 between the cylindrical closures 1a to 1d and the closure on the rear surface 1f. If the operation time of the monitor device is short, air may be supplied to the front cooling chamber 13a to cool the entire case body 1.

In the storage case of the second embodiment, the cooling chamber 13 is used for cooling the case body 1.
a and 13b are formed, but when only the joint 2 of the closed body is sealed, the purge pipe 11 for directly introducing the gas into the purge groove 15 without providing the cooling chambers 13a and 13b.
May be connected. In this case, the purge pipe 11
Since the pressure of the gas acts on the joint 2 via the purge groove 15, the case body 1 can be sealed without interposing a seal member in the joint 2. It is needless to say that it is effective to provide a purge groove 15 in such a joint and seal it even in a case having a joint 2 having a different shape from the storage case.
