【考案の詳細な説明】
本考案は高温度雰囲気内の観察に使用するイメ
ージガイド装置に関するものである。[Detailed Description of the Invention] The present invention relates to an image guide device used for observation in a high-temperature atmosphere.
溶鋼炉内、電気炉内をイメージガイドで観察す
るには、イメージガイド先端部を冷却することが
必要であり、このため、イメージガイド先端部を
冷却水流通管内に、冷却流通管先端からの入光を
可能にするように挿入することが考えられてい
る。 In order to observe the inside of a molten steel furnace or an electric furnace using an image guide, it is necessary to cool the tip of the image guide. The idea is to insert it in a way that allows light to pass through.
この場合、第１図に示すように、冷却水流通管
１′の先端に漏斗状マウス部１１′を設け、視角を
確保できる範囲内でイメージガイド２′の受光端
２１′を潜入させることが、受光端２１′の熱的保
護上、有利である。 In this case, as shown in FIG. 1, a funnel-shaped mouth part 11' is provided at the tip of the cooling water flow pipe 1', and the light-receiving end 21' of the image guide 2' can be inserted into the range within which a viewing angle can be secured. This is advantageous in terms of thermal protection of the light receiving end 21'.
しかしながら、マウス面に入射した熱線A′（赤
外線）が図に示すように、反射を繰り返えしてイ
メージガイド受光面に入射することを考慮すれ
ば、上記受光端の潜入距離がマウスのテーパ角の
ために制約されるといつた問題がある。 However, if we consider that the heat ray A' (infrared rays) incident on the mouse surface is reflected repeatedly and then enters the image guide light receiving surface as shown in the figure, the penetration distance of the light receiving end is the same as the taper of the mouse. There is a problem with being restricted due to corners.

とを特徴とするものである。 The high-temperature image guide device according to the present invention was devised focusing on the above-mentioned points, and includes a funnel-shaped mouth section provided at the tip of the cooling water flow pipe, and the bottom of the mouth section closed with a transparent plate. , the tip of the image guide is inserted into the cooling water flow pipe with its light-receiving end facing the transparent plate, and the mouse surface is formed into a step surface.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.

が、図に示すようにレンズ５を介して透光板から
離隔すれば、それだけ観察対象物の高熱から受光
端４１を有利に保護できる。 In FIG. 2, reference numeral 1 denotes a cooling water distribution pipe, which includes a cooling water outgoing passage 11 and a return passage 12.
2 is a funnel-shaped mouse fitting welded to the tip of the cooling pipe 1, and the mouse surface 21 is a stepped surface. 3
is a transparent plate that closes the bottom of the mouse portion, and it is desirable to use a heat-resistant quartz glass plate. 4
is an image guide, for example, a quartz-based image guide, the tip of which is inserted into the cooling water flow pipe 1, and the light receiving end 41 faces the transparent plate 3. The light-receiving end 41 may be brought into close contact with the light-transmitting plate 3, but if it is separated from the light-transmitting plate through the lens 5 as shown in the figure, the light-receiving end 41 is more advantageously protected from the high heat of the object to be observed. can.
第２図において、Ａは観察対象物からの熱線を
示しており、マウス面２１が階段状とされ、熱線
を真反対に反射する垂直面部分が存在するから、
第１図に示したようにマウス面に入射した熱線が
イメージガイド受光端に入射するのを充分に防止
できる。 In FIG. 2, A indicates the heat rays from the object to be observed, and since the mouse surface 21 is stepped and there is a vertical surface portion that reflects the heat rays in the opposite direction,
As shown in FIG. 1, the heat rays incident on the mouse surface can be sufficiently prevented from entering the image guide light receiving end.
本考案に係るイメージガイド装置は上述した通

できる。従つて、イメージガイドを高温度雰囲気
内の観察に安全に使用でき、かつ観察対象物の温
度領域を拡大できる利点がある。 The image guide device according to the present invention has the configuration as described above, and since the mouse surface of the funnel-shaped mouth portion at the tip of the cooling water flow pipe is a stepped surface, the heat rays incident on the mouse surface can be reflected in the opposite direction. The incident heat rays can be effectively prevented from entering the image guide light receiving section. Therefore, there is an advantage that the image guide can be safely used for observation in a high-temperature atmosphere, and the temperature range of the object to be observed can be expanded.
