持たせるような構造とシステムにより上記問題点を解決
しようとするものである。Traditionally used indirect viewing devices include television cameras, borescopes, periscopes, and fiberscopes, but due to the materials of the components, it is difficult to use them at high temperatures, and the objective lens cannot be used in a steam atmosphere. There is a possibility that steam may condense in the area, resulting in poor visibility. Also, it cannot be used in a corrosive atmosphere. Therefore, an attempt is made to solve the above-mentioned problems by using a structure and system that covers the indirect viewing device with clean gas and provides a cooling function 9 with a function of isolating it from the surrounding atmosphere.
本発明の実施例を第１図により説明する。An embodiment of the present invention will be described with reference to FIG.
高温液体２や高温蒸気３を包含する容器１の内部雰囲気

プ等の間接目視装置を使用する。In order to observe the object to be inspected 4 in the internal atmosphere of the container 1 containing the high-temperature liquid 2 and high-temperature steam 3, an indirect visual device such as a camera or a fiber scope is used.
この間接目視装置は単体では高温に耐えることができな
いだめ、冷却機能を持たせる必要がある。This indirect visual inspection device cannot withstand high temperatures on its own, so it needs to be equipped with a cooling function.

ド１０を取りつける。In the present invention, the objective lens section 6 and the cable 7 of the indirect viewing device are
is housed in a tube 5, and a cooling gas 9 is flowed through the annulus between the tube 5, the objective lens section 6, and the cable 7 to prevent the objective lens section and the cable from being exposed to high temperatures. Furthermore, in order to reduce the amount of cooling gas required, the cylinder 5 is provided with a heat insulating function, and a flexible material is used to improve workability. Further, a spacer 11 is provided between the tube 5 and the indirect viewing device to ensure cooling as uniformly as possible, as shown in FIG. Since the objective lens section 6 is kept at a low temperature, when it comes into contact with the surrounding high temperature steam 3,
Condensation may form and reduce visibility. For this reason, a hood 10 is attached to the tip of the cylinder 5 in order to completely cover the objective lens section 6 with cooling gas.
本実施例によれば、従来から使用されている間接目視装
