  However, in the past, a glass window was installed on the side of the facility containing the vaporizer equipment, and the vaporizer equipment was inspected through the glass window from the outside of the facility. The inside of the glass window was soiled by scattering, and algae sometimes adhered to the inside of the glass window.

  Therefore, even if patrol inspection was performed through the glass window from the outside of the facility, this glass window was dirty, and there was a situation where the indoor vaporizer equipment could not be seen well.

  In order to avoid such a situation, it is necessary for the worker to always clean the inside of the glass window, which is very troublesome and imposes a burden on the worker.

  Also, in order to facilitate the inspection work of the carburetor equipment from the outside of the facility, as shown in FIG. 5 and FIG. It is conceivable to install a water spray shielding plate, etc., but since a large amount of seawater scatters in the vaporizer equipment, a large amount of seawater scatters from the open part of the facility and circulates outside the facility. There is a problem that the worker who is inspecting the patrol gets soaked, and there is a risk that the worker may fall down due to the algae adhering to the floor.

  Therefore, the present invention was created in view of the existing circumstances as described above, and the internal equipment can be easily inspected from the outside of the facility, and the window portion can be easily cleaned from the outside of the facility. A further object is to provide a movable inspection window device that reliably prevents seawater from splashing outside the facility.
