Apparatus and method for automated maintenance

An apparatus for automated maintenance, adapted to maintain an airtight equipment, the airtight equipment comprising a casing which forms an accommodation space and is adapted to accommodate an equipment component in the accommodation space, the apparatus for automated maintenance comprising:

• an automated maintenance machine that stores and transports the equipment component;
• an enclosure, connected to the automated maintenance machine, the enclosure forming an enclosure space, the enclosure selectively connected to the airtight equipment via an enclosure opening, such that the enclosure space is in communication with the accommodation space and forms airtightness wherein:
• the enclosure comprises a maintenance door, and the maintenance door and the enclosure opening are arranged on two different sides;
• and
• in response to a motion signal, the automated maintenance machine drives with the connected enclosure to a position near the airtight equipment;
• and
• a robotic arm, disposed in the enclosure space, the robotic arm adapted to enter the accommodation space to maintain or replace the equipment component, the robotic arm further adapted to enter the automated maintenance machine to take or place the equipment component.
