For example, in Japanese Utility Model Publication No. 57-46360, a rotary base that can be remotely controlled is provided at the bottom of a closed container having a transparent observation window at the bottom, and a rotary mirror that can be horizontally rotated and tilted is installed on the rotary base. There is described a structure in which a wall surface light-projecting device is axially supported and a wall surface light-projecting device is provided below the image-forming mirror, and an image of the wall surface reflected on the image-forming mirror is taken by the image-taking device.

【0004】 この装置によると、炉壁全体の観測を簡単な操作で且つ容易に行うことができ るため、定期的な炉壁の点検、あるいは炉壁補修に先立っての損耗位置、損耗量 等の調査を確実に行うことができ、補修時期、補修内容を的確に把握することが できる。According to this apparatus, the observation of the entire furnace wall can be performed easily and easily. It is possible to conduct a reliable survey, and it is possible to accurately grasp the repair timing and repair details.

【実施例】【Example】

以下図面に示す実施例に基づいて本発明の特徴を具体的に説明する。 The features of the present invention will be specifically described below with reference to the embodiments shown in the drawings.

【0011】 図1は炉内観察装置の斜視図であり、装置本体1は略密閉状の容器として形成 され、これにカメラ等の制御用ケーブル配管、観察窓加熱用のケーブル、冷却ガ スの導入管等を内蔵した支持杆2が連設されている。また、本体1側面から突設 したフード1aに設けられた観察窓3は、透明度に優れた石英ガラス等の複数の 耐熱ガラスを組にして構成されている。FIG. 1 is a perspective view of an in-furnace observation apparatus, in which an apparatus main body 1 is formed as a substantially hermetically-sealed container, in which a cable for controlling a camera or the like, a cable for heating an observation window, and a cooling gas are installed. A support rod 2 having a built-in introduction pipe and the like is continuously provided. The observation window 3 provided on the hood 1a protruding from the side surface of the main body 1 is composed of a plurality of heat-resistant glasses such as quartz glass having excellent transparency.

【0012】 図2は装置本体1内部の概略を示す断面図であり、先端部には観察窓3を指向 するミラー4が取付けられ、さらにこのミラー4に映った炉内像を撮像する観察 手段としてのテレビカメラ5を備えている。テレビカメラ5には、図1に示す支 持杆2内の配線ケーブルによって、図示しない炉外のモニタに接続される。FIG. 2 is a cross-sectional view showing an outline of the inside of the apparatus main body 1. A mirror 4 that points the observation window 3 is attached to the tip portion, and an observation means for taking an image of the furnace reflected on the mirror 4 is provided. Is equipped with a television camera 5. The television camera 5 is connected to a monitor (not shown) outside the furnace by a wiring cable inside the supporting rod 2 shown in FIG.

【0013】 装置本体1内には、支持杆2内の導入管より冷却用ガスが導入され、本体1内 部の高熱に弱いテレビカメラ5等を冷却した後、観察窓3の外に設けた冷却気体 噴出孔6より炉内へ噴出される。A cooling gas is introduced into the main body 1 of the apparatus from an introduction pipe in the support rod 2, and the television camera 5 and the like, which are vulnerable to high heat inside the main body 1, are cooled and then provided outside the observation window 3. Cooling gas is jetted into the furnace through the jet holes 6.

【0014】 観察窓3には、図3の斜視図に示すように、電極9及び両電極9a,9aの間 に設けられた発熱線9bによって構成される加熱手段9が設けられおり、発熱線 9bに外部の電源9cから電気を供給することによって、観察窓3の外面を炉内 温度と同等あるいはこれよりも高温に維持することができる。その際発熱線9b は約1mm程度のニクロム線であるため、観察の支障となることはない。As shown in the perspective view of FIG. 3, the observation window 3 is provided with a heating means 9 composed of an electrode 9 and a heating wire 9b provided between the electrodes 9a and 9a. By supplying electricity to 9b from an external power source 9c, the outer surface of the observation window 3 can be maintained at a temperature equal to or higher than the temperature inside the furnace. At that time, since the heating wire 9b is a nichrome wire of about 1 mm, it does not hinder the observation.

【0015】 図4及び図5は、加熱手段の他の実施例を示し、図4の加熱手段10は、観察 窓3の外周部に帯状の発熱体10aを埋設したものであり、発熱線10aが画画 に全く写らないという特徴がある。10bは発熱体10aに接続された電源であ る。さらに図5の加熱手段11は加熱用ガスバーナで、複数の噴出孔11bを設 けたバーナー本体11aから噴出する炎によって、観察窓3の全面を均等に加熱 することができる。4 and 5 show another embodiment of the heating means. The heating means 10 of FIG. 4 is one in which a belt-shaped heating element 10a is embedded in the outer peripheral portion of the observation window 3 and the heating wire 10a is provided.
