1. An uninterruptible power supply device comprising:
a housing having a rectangular parallelepiped shape;
a plurality of electric units accommodated in the housing; and
a fan unit disposed on an upper surface of the housing, wherein
the upper surface of the housing is provided with an opening from which at least one of the plurality of electric units is exposed,
the fan unit includes:
a fan,
a frame member having a rectangular outer shape and disposed on the upper surface of the housing to surround an outer circumference of the opening, and
a support member that supports the fan above the opening in a state in which the support member is fixed to the frame member,
wherein a gap is provided between a lower end of a first surface of the frame member and the upper surface of the housing,
wherein the uninterruptible power supply device further comprises:
a first blocking member connected to the first surface of the frame member to be slidable in a vertical direction, the first blocking member serving to block the gap in a state in which the first blocking member is in contact with the upper surface of the housing, and
at least one second blocking member inserted through the gap into the frame member to block the opening in a state in which the first blocking member is slid upward and the gap is exposed, and
wherein the at least one second blocking member includes a plurality of second blocking members,
the second blocking members are arranged side by side in an extending direction of the gap,
each of the second blocking members includes:
a blocking portion having a flat plate shape and serving to block a part of the opening,
a guide portion provided at a first end portion of the blocking portion in an extending direction of the blocking portion, and
a handle portion connected to the guide portion,
the first blocking member includes:
a fillet portion having a flat plate shape and protruding in a direction perpendicular to the first surface of the frame member, the fillet portion being provided with a plurality of through holes penetrating through the fillet portion in a thickness direction of the fillet portion, and
a plurality of guide screws inserted through respective ones of the through holes, and
the guide portion is provided with a guide groove for guiding the guide screws in an extending direction of the gap.
