Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for a monitor device or the like.

[0002]

2. Description of the Related Art Conventionally, in a storage case for storing a monitor device, etc., a closing body is assembled into a rectangular parallelepiped cylinder, and a sealing member such as copper or rubber material is interposed at a joint portion of the closing body which needs to be opened and closed. Was sealed. A monitor device built in such a case is installed in the vicinity of the hot finish rolling mill for monitoring, for example.

[0003]

If the above-mentioned storage case is installed under the environment of high temperature, dust, mist such as water and oil, the monitor device and the like stored therein may be damaged. For example, the environment installed to monitor the operating condition of the hot finish rolling mill is a place where the temperature is 60 to 70 degrees and the mist of the cutting oil used in the rolling mill is scattered. In this situation, the chemical contained in the cutting oil dissolves the copper or the rubber material of the seal member to cause the seal failure of the storage case, causing the monitor device to malfunction. In addition, since an incandescent bulb was used as the light source for illumination of the monitor device, if the storage case is installed in a place with severe vibration,
There was also the problem of causing the incandescent bulb to run out. Therefore, the present invention provides a storage case capable of protecting the monitor device and the like stored therein even under the environment of high temperature, dust, and mist.

[0004]

According to a first aspect of the present invention, there is provided a storage case for accommodating a monitor device or the like, wherein a cooling body is formed by a closing body and a covering body, and a fluid is introduced into the cooling chamber and the fluid is discharged from the cooling chamber. A discharge port for discharging is provided. Claim 2
The storage case of the monitor device or the like is provided with a purge groove over the joint between the closed bodies and introduces gas into the purge groove. In the storage case of the monitor device or the like according to claim 3, a cooling chamber is formed by the closing body and the covering body, a purge groove is provided over a joint portion between the closing bodies, and the cooling chamber and the purge groove are communicated with each other. A communication hole is provided to introduce gas into the cooling chamber. According to a fourth aspect of the present invention, there is provided a storage case for storing a monitor device including a camera body and a light source for illumination, wherein an optical fiber lamp is used as the light source for illumination.

[0005]

In the storage case of claim 1, since a fluid such as air or water flows through the cooling chamber and is discharged to the outside from the discharge port,
The inside of the case body can be cooled. In the storage case according to the second aspect, gas such as air or nitrogen introduced into the purge groove leaks from the gap of the joint portion while being exerted on the joint portion of the closing body, and is discharged to the outside. Therefore, without interposing a seal member at the joint of the closed body, moisture in the external environment,
It is possible to prevent dust, mist, and the like from entering the case body through the gap between the joints. In the storage case according to the third aspect, the gas introduced into the cooling chamber enters the purge groove from the cooling chamber through the communication hole, leaks from the purge groove through the gap of the joint portion, and is discharged to the outside. Therefore, the inside of the case main body can be cooled by the gas flowing through the cooling chamber, and the gas pressure acts on the joint through the purge groove. It is possible to prevent water, dust, mist, etc. from entering the case body through the gap between the joints. According to the present invention, since the optical fiber lamp is used as the light source for illumination, even if the storage case is installed in a vibrant environment, the number of failures is less than that in the case where the white-baked ball is used.

【Example】

(First Embodiment) A first embodiment of the present invention will be described with reference to the drawings. 1 is a plan sectional view of the storage case, FIG. 2 is a side sectional view taken along the line AA of FIG. 1, FIG. 3 is a front view taken along the line BB of FIG. 1, FIG. The case body is provided with a monitor device and the like inside the case body 1.
That is, the camera body 30 and its lens 31 are provided in the center of the case body 1, and the optical fiber lamps 33 serving as illumination light sources are provided on both sides of the camera body 30, respectively, and the camera cable 32 and the optical fiber cable 34 are provided. Is extended to the outside through the flexible hose 36. The optical fiber lamp 33 guides the light passing through the optical fiber cable 34 to a lamp of an illuminating section so that the light can be illuminated. Reference numeral 37 denotes a temperature detector mounted 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 controller (not shown) is used. To give an alarm.

The case body 1 is formed of each closed body made of a material such as a steel plate, and the closed bodies 1a to 1d have a rectangular parallelepiped tubular shape by welding or the like in order to minimize the seal portion (joint portion between the closed bodies). It is formed on the rear side closing body 1f
In order to allow the monitor device to be inspected, the cylindrical closing bodies (front surface, back surface, both side surfaces) 1a to 1d and screws 3 are fastened and detachable. On the other hand, the front closure 1e has a structure that can be opened and closed as described later. In addition, instead of interposing a seal member on each joint 2, instead of this,
A blow pipe 7 for introducing a gas such as air or nitrogen is laid inside the case body 1. Also, the tubular closing bodies 1a to 1
In d, cooling chambers 13a and 13b are formed by covering the outside with a coating 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, the partition plate 14 is provided to divide the cooling chamber into two parts, the front side and the rear side of the case body 1. The purge pipe 11 and the discharge port 16 are provided for each of the partitioned front cooling chamber 13a and rear cooling chamber 13b. The cooling chamber does not have to be provided in all the closing bodies, and may be formed corresponding to only the closing body 1a, for example.

A front closure (opening / closing lid) 1e 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 rotating shaft 22, and the piston 21 is connected to the air cylinder 20 via air pressure.
When the extension and forward movement is performed, the opening / closing lid 1e is correspondingly moved to the hinge 2
It is rotated about 3 and released (Fig. 4). On the other hand, when the piston 21 is moved back and forth to the air cylinder 20 via air pressure, the opening / closing lid 1e is rotated about the hinge 23 and closed. Reference numeral 24 is a detector such as a proximity switch provided facing the open / close lid 1e, and detects the open / closed state of the open / close lid 1e via the detector 24.

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

Next, the operation of the storage case having the above-described 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 side cooling chamber 13a is supplied from the purge pipe 11 respectively.
When air is supplied to the cooling chamber 13b on the rear side and the cooling chamber 13b on the rear side, the air from the blow pipe 7 is guided to the inside of the case body 1, and the inside is kept at a pressure higher than the pressure of the installation environment (for example, atmospheric pressure). A part of the air in the case body 1 leaks to the outside of the low pressure through the gap of the joint portion 2 of the closing body. Therefore, the case body 1 can be sealed without interposing a seal member on the joint portion 2. On the other hand, purge pipe 1
The air guided from 1 flows through the front side cooling chamber 13a and the rear side cooling chamber 13b, respectively, and is discharged from each discharge port 16. Therefore, the inside of the case body 1 can be insulated and cooled.

On the other hand, when the monitor device is operated, the opening / closing lid 1e is opened via the air cylinder 20. Then, in the same manner as described 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 introduced into the case body 1 in the same manner as described above, thereby joining the joint portion. 2, the air blown out from the case body 1 is released and released to the outside to replace the inside of the case body, and the inside of the case body is cooled, and the air flowing through the cooling chambers 13a and 13b is also used. The inside of the case body 1 is cooled. Further, the air from the curtain pipe 4 is closed by the upper and lower closures 1a, 1 respectively.
It passes through a curtain passage 5 provided in b and is blown out from a large number of outlets 6 to form an air curtain. For this reason, even if the opening / closing lid 1e is opened, the air curtain shuts off, so that it is possible to prevent moisture, dust, mist, and the like from entering the case body 1. Further, 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 vibrant environment, the situation will not occur as if the ball is burned out as compared with the case where a white-baked ball is used, and a failure will occur. Few. When a liquid such as water is used as the fluid to be supplied to 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 may be provided to allow the fluid to flow evenly through each of a and 13b.

(Second Embodiment) Next, 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 the different points will be described. In addition, in FIG. 5, members corresponding to those in FIG. 2 are denoted by the same reference numerals. In this embodiment, in addition to cooling the case body 1, the closing bodies 1a to 1d, 1e,
The purpose of the present invention is to enable sealing without interposing a seal member on the joint 2 of 1f. That is, a purge pipe 11 for introducing a gas such as air or nitrogen is connected to each of the front side cooling chamber 13a and the rear side cooling chamber 13b formed in the tubular closing bodies 1a to 1d, and each cooling chamber 13a,
13 b are communicated with the purge groove 15 via the communication holes 40. In addition, the purge groove 15 is formed over substantially the entire length of the joint portion 2 of the closing body, for example, the joint portion 2 of the upper surface closing body 1a and the rear surface closing body 1f as shown in a partial perspective view of the inside of FIG. It is provided across. A purge groove 15 is also provided in the joint portion 2 between the surfaces 1a to 1d of the tubular closing body and the front closing body (opening / closing lid) 1e.

Since the storage case of this embodiment has the above-mentioned structure, first, when the monitor device is not operated,
The opening / closing lid 1e is kept 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, the air pressure is applied to the joint portion 2 of the closing body through the purge groove 15, and the air leaks from the gap of the joint portion 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 side cooling chamber 13 a and the rear side cooling chamber 13 b, and further, the air is ejected from the joint portion 2 through the purge groove 15, so that the joint portion 2 can be cooled. The case body 1 can be sealed without interposing a seal member, and environmental moisture, dust, mist, etc. can be prevented from entering the inside of the case body 1 from the joint portion 2.

On the other hand, when the monitor device is operated, the opening / closing lid 1e is opened via the air cylinder 20. Then, the air is supplied from the blow pipe 7 and the curtain pipe 4, and the supply from the purge pipe 11 is stopped. Then, the air guided from the blow pipe 7 can cool and seal the inside of the case body 1, and the air from the curtain pipe 4 forms an air curtain, thereby Prevents leakage of moisture, dust, mist, etc. Incidentally, the reason why the supply from the purging pipe 11 is stopped when the opening / closing lid 1e is opened is to prevent a large amount of air from being discharged from the purge groove 15 at the opening portion. It is effective to introduce air from the purging pipe 11 only into 13b to cool the case body 1 and to seal the joint portion 2 between the tubular closing bodies 1a to 1d and the closing body on the rear surface 1f. However, when the operating time of the monitor device is short, air may be supplied also to the front side cooling chamber 13a to cool the entire case body 1.

In the storage case of the second embodiment, the cooling chamber 13 serves to cool the case body 1.
Although a and 13b are formed, when only the joint portion 2 of the closing body is sealed, the purging pipe 11 that directly introduces the gas into the purge groove 15 is provided without providing the cooling chambers 13a and 13b.
May be connected, and in this case, the purging pipe 11
Since the gas pressure from the above acts on the joint portion 2 via the purge groove 15, the case body 1 can be sealed without interposing a seal member on the joint portion 2. Needless to say, even in the case having the joint portion 2 having a shape different from that of the storage case, it is effective to provide the purge groove 15 in the joint portion to perform sealing.

[0016]

According to the storage case of the present invention, the inside of the case body is cooled by flowing a fluid into the cooling chamber.
It is possible to protect the stored monitor device. In addition, since the case body can be sealed by the purge groove provided at the joint portion without interposing a seal member at the joint portion, environmental dust,
It is possible to prevent the intrusion of water and mist and protect the stored monitor device and the like. Furthermore, by using an optical fiber lamp as a light source for illumination, even if the storage case is installed in a vibrant environment, there are few failures.
